Liu Dazhi turned his gaze and turned to Li Ruoyu again, seeing Li Ruoyu thinking on the side, he asked with a smile: "Comrade Xiao Li, do you have any new ideas?" Let's hear it! ”

Li Ruoyu no longer hides at this time, if he can make the ready-mixed concrete industry in Shanghai and even the whole country develop faster and better, he doesn't mind being high-profile, after all, Li Ruoyu plans to start his own ready-mixed concrete enterprise soon, so he met Liu Dazhi's gaze and said without humility or arrogance: "Okay, I'll talk about my immature ideas." The mixing building you see now is a kind of concrete mixing building that we have introduced from Germany, although at present, it is still okay. However, if we want to say that the development of concrete batching plant in the future must be in the direction of microcomputer control automation, this kind of batching plant is still in the way of manual metering control, and it will definitely lag behind in the future. Therefore, the newly built batching plant can boldly adopt the method of microcomputer automatic control, which can not only improve the production speed, but also improve the accuracy of measurement, so as to better control the quality of concrete. ”

When Liu Dazhi heard this, he immediately became interested, and he asked curiously: "Oh, I didn't expect Comrade Xiao Li to have such a deep understanding of the mixing building!" However, is microcomputer control really feasible? Now there are manufacturers in the world that can produce this kind of mixing building? ”

The rest of the people were also curious waiting for Li Ruoyu to answer, after all, most people in this era don't even know what a microcomputer is, let alone use a microcomputer to realize the automated production of the mixing building. Even Liu Yulong, the chief engineer of Huhai No. 1 Construction Mixing Plant, an authority in the Huhai concrete industry, heard of the microcomputer-controlled mixing building for the first time. He was also thinking, where did Li Ruoyu know about this kind of microcomputer and the microcomputer-controlled mixing building?

Li Ruoyu said calmly: "The core of the so-called automated concrete mixing plant is a microelectronic computer and PLC automatic programming control device. With these two equipment, it is possible to realize the automatic control of all the equipment in the mixing building. This is the most advanced science and technology in the world at present, of course, at present, microelectronic computers are developing relatively rapidly abroad, and we do not have the ability to develop microelectronic computers in China, so it is not surprising that everyone does not know. After installing a set of specially designed automation control software for concrete mixing plant on the microcomputer, the computer system can send various instructions to the PLC, and the PLC can then transmit the electrical signal to the relevant equipment, so as to realize the automatic control. For example, we input the commonly used concrete mix into the microcomputer automatic control software, and you can call out a certain concrete mix ratio that needs to be produced at any time during production, and then enter the number and number of discs produced by the car, so that you can automatically produce this car of concrete. All kinds of raw materials can be measured at the same time, and the control signal output by the software will realize the automatic opening and closing of the door of the silo, so that a high measurement accuracy can be achieved. Under normal circumstances, the operator only needs to call up the mix ratio, input the car number and square quantity and other parameters, and then execute the task of the car, and then a qiē is carried out automatically, the operator has to do just to observe whether there is an abnormal situation, and how the working performance of the concrete is, if the concrete slump is small, you can manually add water, and you can deduct water if it is large. It's that simple. ”

As soon as Li Ruoyu's words fell, everyone present was shocked on the spot. Such an advanced automated production of concrete mixing building, they have never heard of it, let alone explain the truth, although they do not understand too much how this automatic mixing building realizes automatic production, but its application prospect really shocked the people present! You must know that ready-mixed concrete is still a new thing in China, that is, people in the industry think that it is just a very extensive simple processing, and how can they think that concrete production can be automated with high technology. However, Li Ruoyu said that the microcomputer control automation mixing building, its production efficiency is not generally high, if that is the case, I am afraid that it is a 120 production line, which can produce more than 1,000 cubic meters of concrete in a day, at least more than five times that of the current manual control.

Liu Dazhi said happily: "Comrade Xiao Li, what you said is really an eye-opener for us!" I didn't expect that our Huhai Yijian mixing plant is still a place of Crouching Tiger, Hidden Dragon! It's just that this kind of automatic mixing building you are talking about, where is it sold? ”

Everyone looked at Li Ruoyu expectantly, yes, this kind of automatic mixing building is so good, but I haven't heard of any country that has this kind of mixing building for sale!

Li Ruoyu smiled and said: "Secretary Liu, I don't know too well if there is such a microcomputer-controlled automatic mixing building for sale abroad." But we can put forward this demand to foreign large-scale concrete machinery manufacturers, I believe that with the strength of those large-scale concrete machinery manufacturers, it is completely possible to make this kind of concrete mixing building. In addition, we don't have to rely completely on foreign countries, we can cooperate with our domestic construction machinery manufacturers and units such as the Institute of Computer Science of Shuimu University or the School of Microelectronics of Fuming University to build an automated concrete mixing building with our Chinese characteristics. I believe that in the future, the market of concrete machinery in China is very large, and those manufacturers will not see the business opportunities here. ”

Hearing Li Ruoyu say this, Liu Dazhi and Cheng Nantong are slamming their thighs, Li Ruoyu's words make them have a feeling of enlightenment or sudden opening, yes, if they can seize such an opportunity to make China's concrete construction machinery and ready-mixed concrete industry walk in the forefront of the world, then they will become the greatest contributors in the history of China's concrete development, and it is not in vain that they have served as the leaders of the Huhai Construction Engineering Administration for so many years, and even, they are thinking that if they really achieve the goal that Li Ruoyu said, then their official career will be smoother! In the Huhai Construction Engineering Administration for many years, although they have managed the Huhai construction industry in an orderly manner, but there is no breakthrough contribution, so they are always thinking about making a little contribution to the Huhai construction industry and even the national construction industry in their lifetime.

Liu Dazhi and Cheng Nantong glanced at each other, and they both saw a great hope in each other's eyes. Liu Dazhi said loudly: "Good, good, good!" Comrade Xiao Li, you have taught all of us a lesson today, and it seems that our vision is still too backward and outdated. I think we should all learn from Comrade Xiao Li, and to do our construction industry, especially the concrete industry, we must be as good at thinking and innovative as Comrade Xiao Li, so that our cause can do better! We can't see that our concrete industry is very profitable now, and we are satisfied with the status quo, we have to look further and plan for the future of our ready-mixed concrete industry as soon as possible. ”

Fan Baogen also felt that there was light on his face, after all, Li Ruoyu was his subordinate, and he was highly appreciated by Secretary Liu, and he also felt deeply honored. Fan Baogen patted Li Ruoyu's shoulder beside him and said happily: "Ruoyu, you spoke so well today!" Let's talk about what equipment can be improved in our mixing building, so that everyone can open their eyes. ”

Li Ruoyu thought for a while and said: "First of all, our aggregate conveying equipment needs to be changed, and the current design of the dragline type is difficult to adapt to the material needs of the future automated production mixing building. This kind of dragline feeder has low feeding efficiency and slow speed. So I think in the future, we can use the whole belt conveyor, for example, after the sand and gravel ship docks, use the grab to put the sand and gravel directly into a small hopper, and connect the belt conveyor below, so that it can be transported to our aggregate storage warehouse for storage. Then, from the aggregate storage warehouse to the aggregate bin of the mixing building, you can use the loader to load the material, you can also set up an underground tunnel below the aggregate warehouse, and the same belt conveyor is used, and the microcomputer automatic control is used to regularly supplement the aggregate to the aggregate bin at the top of the tower mixing building, and each of the aggregate silos at the top can hold two or three hundred tons of materials. The latter way production efficiency will be higher, because the aggregate is regularly supplemented, as long as the material level reaches the lower limit, it will be automatically replenished, that is to say, there are more than two or three hundred tons of aggregate in the top aggregate bin at any time, and then when measuring, the aggregate will be directly put into the aggregate scale from the aggregate bin above, so that the time waiting for the conveying of the intermediate belt is not passed, and the time of measurement is greatly saved. ”

As soon as Li Ruoyu's words were finished, everyone was extremely shocked, they were wondering why they hadn't thought of it? It is true that the design of the mixing building is too backward, for example, the aggregate must be measured, and then loaded into a hopper, and pulled to the top of the mixer by using a slide rail, which not only waits for a long time, but also the hopper can not be too big, and it can be loaded with two or three tons at a time, and the efficiency is naturally much worse.

Cheng Nantong laughed and said: "Comrade Xiao Li, I don't know how you got there, but after I listened to it, I feel that your thinking is very correct!" No matter what position you work in, you must learn more and think more, so that you can be like Comrade Xiao Li and apply all the knowledge you have learned in practice, which is innovation! Only by continuous innovation can our construction industry maintain its vitality, develop better and faster, and make our contribution to the construction of our country. Today to Huhai a construction mixing plant, it is really a harvest, on behalf of the Huhai Construction Engineering Administration, thank you, Comrade Xiao Li! I hope you will continue to give full play to your wisdom and talents in your position, and we will definitely reuse outstanding young talents like you! ”

Hearing Cheng Nantong's words, everyone understood that this Li Ruoyu would soon soar into the sky! Especially Zhou Jing, now he really feels that he is at the end of the road, not only did he not suppress this unusual subordinate, but also let himself show his appearance in front of his superiors, he also knew that his manager might be at the end of his life, and he didn't know if he could keep this iron rice bowl! Now his resentment towards Li Ruoyu is even deeper, if it weren't for Li Ruoyu, he would definitely be reused by the leadership, and even continue to move towards the peak of his career. But now, it's all over.
