Chapter Ninety-Two: Building a Windmill

Back at Yaogang, Zhang Zhimu organized another meeting of the cadres. The first topic of the meeting was the takeover of the smelter. First of all, it was determined that Li Dong would be specifically responsible for the overall work of the smelter, and Lu Chengxiang would send two people who knew the new bookkeeping method to do the accounting room. Li Dong wanted Li Yunhe to go to the smelting factory with him, but Zhang Zhimu did not agree. Zhang Zhimu said: "Li Yunhe is still of great use here. This Xiurong smelting plant is only our first smelter, and there will be a second and third one in the future. Li Dong went to take over the smelting plant this time, and he should bring a few more young and literate people with him, and pay attention to cultivating people. Our business also needs more management talents. Li Dong only had one to two years to straighten out the management of the smelter. When a successor is formed, he must be withdrawn. We have more to do. ”

Li Dong said: "I brought some people, such a big factory, still have to use the original people." There's a lot of talent there. Find a way to get them to come back to their hearts. Hearing Li Dong say this, Zhang Zhimu was very happy, he knew that Li Dong was a person who could make great things, knew the key points of the matter, and knew how to deal with it.

Zhang Zhimu said: "Now things are going in a few steps. First, we first prepare our own personnel and set the management personnel. The guards were first led by Liu Yun and brought the more than 500 cavalry there, and the places where they lived were all ready-made. The second step is for Lu Chengxiang to bring all your people to help Li Dong do a good job of counting and taking over the original accounts and property, and he must find out all the family resources of the smelter and do not omit anything. The financial personnel of the smelter can be appropriately increased. Then follow our bookkeeping method and re-establish the accounts. It is also necessary to train the former bookkeepers. Establish a sound financial system, and Li Dong must cooperate with this. Li Dong must take the lead in abiding by financial discipline. ”

Li Dong said: "Mr. Zhang rest assured, in the past, all levels of the smelter were greedy for ink by all means, and I will never allow such a thing to happen again." ”

Zhang Zhimu said: "Okay. The third point is that we need to make a large investment in the smelter, and we will build several steel-making furnaces next to the original iron-making furnaces, so that a lot of iron can be directly made into steel. In order to improve the efficiency of ironmaking and the quality of steelmaking. We have to build coke ovens, and with coke we can make better steel. The by-industry brought by coking is even more incredible. In the future, the production of horse-drawn carriages will gradually be moved to the vicinity of the smelter, and a production plant specializing in the production of horse-drawn carriages will be established. In this way, it can be centrally managed, and the steel plate can be transported directly to the factory nearby. ”

The workers' dormitories and other living facilities of the smelter should also be greatly improved. Lu Qi's asbestos blended fabric should be woven as soon as possible, and the furnace workers will wear protective clothing in the future. There should also be fireproof gloves and fireproof shoes. Masks must be distributed to workers, and in short, we have to build a brand new smelter. We will treat the workers there as our brothers, and the workers will treat us as relatives.

Lu Chengxiang said: "Don't worry about anything else, we must pay close attention to this matter of cultivating people." I don't think I'll have to wait, now I can have more than 40 people here, let's start a class first. Zhang Zhimu said: "Okay, let's start now, you arrange the course." I'll talk about arithmetic, and Mr. Lu Bingyi will arrange people in the text class. Courses such as accounting and commodities will be taught by Mr. Lu himself. When I have time, Mr. Yan also wants to talk about horses to the students. ”

Li Yunhe said: "I am also preparing to open a manufacturing class, and the company will arrange people to take other courses." There are some courses that Lu Qi and I can take. ”

Zhang Zhimu said that it was great, so that we could slowly cultivate talents. As for talents, we should cultivate them ourselves, and we should also recruit talents from outside, and we should also find some other talented people.

After the meeting, Li Yunhe stopped Zhang Zhimu and said, "The windmill parts are ready, just wait for you to come back and install it." As soon as Zhang Zhimu heard it: "Then what are you waiting for, let's go install it now." ”

Zhang Zhimu saw that the processed leaves had been painted with white paint, and the tips of the leaves were painted red. The connecting base of the fixed blade is six feet in diameter, and the mortise and tenon structure connected to the blade is also machined. Because Zhang Zhimu knows that with such a huge blade, the centrifugal force that rotates is amazing, and if the blade is not fixed, it will be very unsafe. Therefore, this connecting base is specially selected by Zhang Zhimu for processing several pieces of hardwood, and after installing the blades, it is necessary to wrap a few steel bars around the base.

The six-zhang high cement tower is definitely a huge monster on this kiln post, Zhang Zhimu looked at the workers who were painting the tower white on the scaffolding, and said to Li Yunhe, when the wind turbines are installed, the scaffolding will be removed. The problem is that it's always windy here, and it's going to take a bit of effort to hang these three big guys up. Li Yunhe said: "I have discussed with Lu Qi and them, as long as a few poles are fixed on the top of the tower, this guy can be hoisted, and as long as a few ropes are tied below, he is not afraid of the wind." Zhang Zhimu entered the tower through a small door at the bottom of the tower and saw that the vertical shaft and the bevel gear for transmission had been installed. Li Yunhe said: "This vertical axis is made of a whole log, and it takes a lot of effort to process it. The whole piece of wood is spun and turned into a thick cylinder with a knife. Now it sits on the upper and lower two thrust bearings. ”

Out of the tower, Zhang Zhimu told Li Yunhe that the most important thing was to lift the frame of the windmill first, then install the tail rudder, and finally hang the blades. Now that the paint on the blades has dried, immediately install the three blades on the base, and after installation, you will also pour glue between the gaps in the mortise and tenon joints, and it is best to nail it with steel tape so that it is not connected more strongly. And the copper wire of the lightning rod must not be entangled in the blades. Today, I will move the windmill up, install it on that thrust bearing, and install the wind rudder as well. Tomorrow I will install the blades and let the glue between the blades and the base dry overnight.

This windmill frame sits on the thrust bearing at the top of the tower, and the cylinder below sits right into the inner hole of the thrust bearing. The rotating shaft connecting the blades is mounted transversely on the windmill, and the rudder is mounted at the rear of the windmill. A bevel gear is mounted on this shaft, and this bevel gear is just in line with the bevel gear at the top of the vertical shaft, and this shaft is rotated by the fan blades to transfer power to the vertical shaft.

Waiting for Lu Qi and others to fix the wooden poles on the top of the tower, the hoisting work began. Through the pulley tied to the wooden pole at the top of the tower, there are twenty people on the ground to pull the rope, and pull the windmill to the scaffolding at the top of the tower, and the people on the top of the tower use the method of rolling wood to push the windmill to the top of the tower little by little. The people around him worked together, and they sat firmly on the thrust bearing. Then Lu Qi personally adjusted the contact distance of the umbrella bearing, and then fixed the umbrella bearing, and the windmill frame was installed. Then it's much easier to install the tail rudder. Zhang Zhimu told Lu Qi that the places where the bearings are easy to enter the ash must be sealed with oil seals. This so-called oil seal is made of felt and oil, mainly to keep out dust. Li Yunhe and a few workers are installing the blades on the blade base, which takes up too much space. In his previous life, Zhang Zhimu knew that the blades of a 30-kilowatt wind turbine were only six or seven meters long, but Zhang Zhimu knew that the shape of the blades was a high-tech problem, and the efficiency of his blades and rotation mechanism would be very low, and it was impossible to compare. However, if it is used to carry water, it is not a problem to be fast or slow. I just don't know how the two bearings dissipate heat when the wind speed is fast. We'll see when the time comes.

Wu Jinfeng (Wu Shan's father), the kiln director of the cylinder kiln, drove a carriage to pull a large cylinder and two cylinder pipes to report the good news. The two tubes are one foot thick, three feet and five feet long, respectively.

The kiln was opened today, and as soon as the temperature dropped, he brought things in. Zhang Zhimu touched the still warm vat and said: "Congratulations on your good start, today you can let the workers drink some wine and add two dishes to everyone to celebrate." I'll visit you all when I have time. At this time, the cadres of the kiln gang also came to congratulate Wu Jinfeng. For a while, Wu Jinfeng was overwhelmed. This is an honest man, originally thought that he himself was an outsider, although Zhang Zhimu gave him the position of kiln chief, but he never asked about other things in the kiln, and he was a very inconspicuous figure in the kiln. I didn't expect that I was so valued by everyone today, and I was very happy.

The congratulatory people dispersed, and Zhang Zhimu took Wu Jinfeng to his office. On the drawing, he drew a few sketches for Wu Jinfeng with a pencil. One is a kind of jar, with a big belly and a small mouth, with double handles, and the mouth should have a lid that can be tightly covered; One is a large bathtub and sink, both of which are modeled after those of previous lives.

Because the coke is about to be made, these large jars can be used to hold kerosene, gasoline and other things that have been diverted. In the future, chemical equipment and sulfuric acid will be used.

Zhang Zhimu asked Wu Jinfeng to burn some more cylinder pipes with an inner diameter of five inches. Because in some places, the water supply does not need such a thick pipe. The smelting plant that is about to be taken over has many facilities to be renovated, and this water supply and discharge must be solved first.

The next day, the wind was a little strong in the morning, so Zhang Zhimu didn't let everyone lift the blades. By noon the wind had suddenly subsided and had almost stopped. Zhang Zhimuxin said: "God takes care of me." "Ordered everyone to lift the blades immediately, and as soon as more than 20 people exerted their strength, the blades were hoisted. At this time, Zhang Zhimu personally participated in the installation of the blades at the top of the tower, and after the blades were hoisted, several people on the top of the tower tied the blades with ropes and pulled them to the shaft of the windmill, and Lu Qi personally screwed the fixing screws one by one. These screws were made by Li Yunhe himself, and the screws and screw mothers were tried and matched very well below, so on top, the installation was also very smooth. After the blades were installed, a round red hood was fastened to the head of the windmill axle, so as to make the windward resistance less and look good. Since the scaffolding has not been removed, the blades of the wind turbine are still tied to the ground with ropes, so that the windmill cannot rotate yet.

Then it's time to start removing the scaffolding layer by layer. If you come up in the future, you will have to pass through the steel ladder in the tower.

When all the scaffolding was removed, Zhang Zhimu let go of the rope that bolted the blades. At this time, the wind is very small, and the blades have not yet turned. Zhang Zhimu said: "You don't need to look at it, go back to eat first." ”

But before Zhang Zhimu's meal was finished, Xiaoqing and Xiaohu ran in and shouted to Zhang Zhimu: "It's turned around." Zhang Zhimu hurriedly finished the rest of the meal and followed the children outside. I saw that the windmill was really slowly turning. White towers, white leaves, the tips of the leaves are red, and the center of the leaves is buttoned with a red cap. It looks very beautiful, and when you come to the bottom of the tower, you can hear the whirring sound of the blades turning and the squeak of the gears. Zhang Zhimu asked people to turn the wheels on the rotating shaft of the ground and connect them with the wheels on the shaft of the waterwheel. As soon as the belt was tightened, the waterwheel turned, and the water lifted by the waterwheel flowed into a wooden trough, and flowed down the trough to the pool that was plastered with cement inside and out.

All the people in the kiln gang came out to see this incredible windmill. This windmill is like magic, and even passers-by stop on the side of the road and look at it for a long time before turning back and leaving. It only took half a day, and after an extra night, the pool was about to be full. However, Zhang Zhimu looked into the well, and the water level had hardly changed, and Zhang Zhimu said to Chen Yufeng: "We have drilled a sacred well." The flow of water from this well is sufficient for us. When your ground is level, water it all over it. My rubber grass needs to be planted first. ”

Chen Yufeng said: "Today, the cylinder pipe of the cylinder kiln can be pulled over, first the main channel is paved with the cylinder pipe, and the joints are sealed with putty composed of tung oil and lime, and then you can put water to water the ground." It seems that the hillside land that has not been harvested for ten years has just made you watered the ground. As long as we do not suffer from the locust plague, next year's grain from these dozens of lands will be enough for us to eat. When the earth is level, there are at least seventy inclinations. A yield of 200 catties per mu is terrible. ”

Zhang Zhimu said: "There is a locust plague, as long as it is not a locust, I have a way." Do you remember that I bought so many chickens, ducks and geese in Xuzhou? When I was ready to have locusts, I put them in the field and let these chickens and ducks go and destroy them. But if it's a locust, there's no way to do it. ”

Seeing Li Yunhe and Lu Bingyi coming over together, Zhang Zhimu said to the two that the two of them had to work hard to design a set of pipe network diagrams for the tap water and sewerage of the entire kiln. We use our burned cylinder pipe for the sewer pipe, and steel pipe for the water supply. The water and sewer pipes should be separated from the heating pipes. Let's make the faucets out of copper, and I'll get rubber out again in a few moments, and the women have already got a lot of rubber grass. This way the faucet will not leak. There must be a sewer under every faucet so that you don't get mud everywhere.

The two of them went to do it at once. Zhang Zhimu returned to his office and began to design the bathhouse. With tap water, you can use the waste heat from the iron furnace to heat the tap water for bathing.

The bathhouse designed by Zhang Zhimu is completely in accordance with the model of the previous life, divided into two major parts of the woman, and the bath is also divided into hot and warm water, and the most important thing is to install a shower that can adjust the flow of hot and cold water by itself to control the water temperature. There is no way, and now the shower head has to be made of copper. The bath is made of terrazzo, and it is much more convenient to have cement. The drainage ditch under the bath was also covered with an iron grate. In order to make it easier for night shift workers to take a bath, oil lamps are also installed in the baths. In this way, those workers can take a shower and change into normal clothes after work.

Zhang Zhimu was designing a bathhouse here, and Li Yunhe ran in again and said, "The pool is about to be full, and the water will flow out if you release it again." What to do?"

Zhang Zhimu said: "Go and bring out one of your lathes, and I will try to use it to bring the lathe." Li Yunhe hurriedly arranged for someone to disassemble the lathe, lift it under the fan, and assemble it again.

This time, I connected the belt that drove the waterwheel to the lathe. As soon as the belt is tightened, the lathe slowly rotates, and the speed is getting faster and faster. Li Yunhe said that this is much stronger than that of the cow, fast and stable. The faster the machining, the higher the accuracy. Li Yunhe stopped the lathe, stuck a steel rod, and tightened the belt, after the lathe rotated steadily, Li Yunhe tried to use the turning knife to enter the knife little by little, only to see sparks splashing, and the steel rod was processed brightly. Stop the lathe, remove the steel rod, let it dry for a while and touch it with your hands, the steel bar is very smooth.

Zhang Zhimu said to Li Yunhe: "You press me two thin steel plates that are as thick as a saw blade and make a circular saw blade." Then give it a try here. At night, when the windmill is not in use, people must go up to the tower and move the direction of the blades away from the windward side. This can protect the blades, otherwise it is easy to fly when the wind is strong, causing damage to the blades. ”

Li Yunhe said: "I will arrange someone to be in charge of this windmill. ”

Zhang Zhimu said: "I'll give you a size, you help me car a few steel pipes and steel rods, require the steel rod to be inserted in the steel pipe is just right, smeared with oil can slide freely, and when the steel pipe is inserted into the steel pipe, one end of the steel pipe is blocked, and the steel rod is not good to pull out as the best." ”

The inner diameter of the steel pipe designed by Zhang Zhimu is three points and the outer diameter is six points. The length is a foot; The outer diameter of the steel rod is three points, and the length is also one foot. This is ready to be made as a mercury thermometer.

Hearing the thermometer, Li Yunhe and the others didn't understand.

Zhang Zhimu said to them seriously: "We all know that boiling water is very hot, and when it freezes, it is very cold. That's the temperature difference. Also, it's hot right now, and it's cold in winter. It is also different in temperature. So how much difference is there? We have to have a standard so that we can compare. Usually we set the temperature at which the water freezes to zero degrees and the temperature at which the water boils to 100 degrees. This interval between zero and 100 degrees is divided into 100 intervals, and one interval is one degree. All we're going to do today is a thermometer. This thermometer is made using the principle of thermal expansion and cold contraction. Everyone knows that when the iron is red, it will be a little bigger than when it was not red. When it was cold, it retracted. This is called thermal expansion and cold contraction. In fact, many objects have thermal expansion and cold contraction. The mercury we want to use is the obvious substance of thermal expansion and cold contraction. ”

Li Yunhe asked: "How can mercury and steel pipes measure temperature?" ”

Zhang Zhimu said: "I want to insert half of the steel rod into the steel pipe, fill the empty steel pipe with mercury, and seal this end of the steel pipe with screws. Then put it up and put it in ice water, because the temperature of the water is 0 degrees. At this time, we carve a mark on the bar, and this mark is the zero mark. Then we put the thermometer in boiling water, and when the mercury expands when it heats up, it pushes the steel rod out. At this point, we carve a mark on the steel rod. This is the position of 100 degrees. From the position of zero degrees to the position of 100 degrees, we divide it equally by one hundred, and we all carve traces on the steel rods. In this way, we will know what the temperature is when the steel rod shows any traces. ”

Li Yunhe said: "Then I understand. What about sub-zero? Zhang Zhimu said, according to how long it is to continue to carve down, you will know, and it is the same for more than 100 degrees.

Lu Qi asked again: "If the mercury flies less, it's not allowed." "Zhang Zhimu is right, so your steel rods and steel pipes must be processed with high precision. Moreover, it needs to be verified after a while. When not in use, be sure to put it in a bamboo tube, and put some sulfur powder in the bamboo tube. Because mercury is very toxic, but sulfur powder can absorb mercury, so this thing must be put together with sulfur powder. Later, when we have glass, it will be good to make a sealed thermometer. Remember, if you find that there is a mercury leakage, you must use sulfur powder to absorb it in time, otherwise it will be very harmful.
