Chapter 139: Distribution

I can't go back tonight, so Li Lian burned the potatoes by the fire pond, Su You mixed some spicy rice oil, Sichuan pepper, salt powder, dipped in the potatoes, and chatted with Li Laohan and Li Dazhuan while eating.

Zhuo tube well is the big eye on the top, the big eye on the upper casing to isolate fresh water, and then the small eye on the lower halogen.

The halogen-producing eye is corroded by brine over the years, or the stratum changes, and sometimes the cave wall collapses, which is called "collapse".

The collapse will cause the rock to fill the halogen hole, making it impossible to absorb the brine.

Sometimes some tools fall into the well, or other man-made blockages, which are called "piles", which can also lead to the inability to draw brine.

Now several people are discussing how to eliminate these faults, as well as what processes and tools are needed to repair deep wells.

Li Laohan believed more and more that Su You had been taught by the Yanguan family, and all kinds of ingenuity made the questions he thought about every day be answered one by one, and gradually even Li Dazhuan was speechless, and it became Li Laohan asked questions and Su You answered.

In addition to this, there are many crafts.

Li Laohan also listed the family heirloom craft, and Su oil inspired each other and referenced.

The brine is drawn with a single-angle car or float, connected to the cylinder, and the brine is drawn out of the well.

Su Dongpo later recorded: "The difference between the bamboo and the small one goes in and out of the well as a bucket, there is no bottom and the top of it, hangs the ripe skin for a few inches, enters and exits the water, and the air opens and closes from breathing, and a tube causes several buckets of water." ”

Cooked skin is a one-way valve at the bottom of the bamboo tube that is placed in the tube. When entering the well, it is washed away by the well water, the brine is injected, and when it is lifted, it is pressed by the brine in the cylinder, and the bottom of the cylinder is sealed, and the brine can be extracted from hundreds of meters underground.

However, Dahongjing and Wulongjing are both self-blowing wells, and it will take hundreds of years to use this equipment. Now it can only be used as a technical reserve for other wells to be developed in the future.

The well brine is turbid, generally concentrated at 7 to 10 degrees, and the salinity of such brine is low, which will lead to high fuel costs.

In order to increase the concentration of brine, it is necessary to dry brine, and the equipment includes support frames, dams and other facilities.

The dam is generally 60 meters long and 20 meters wide. The stakes are generally about 30 meters long and 5 meters high. The structure is like a figure-eight shape, with a wooden bucket, and the support frame is covered with bamboo trees, and the top is made of a "heavenly boat".

The heavenly ship is ten meters long, one meter high, and fifteen meters wide, and the heavenly ship is placed in the middle of the top end of the support frame, and the bottom of the heavenly ship has an empty bamboo tube that stretches out to both ends of the support frame and is as long as the support frame, and the bamboo tube is drilled with irregular small eyes.

On one side of the bracket there is a cart like an isosceles triangle dome, six meters high and five meters in diameter, worn by a transverse axis. Bamboo tubes are attached to the outer ring of the waist bottom, each about 30 to 50 centimeters long. And install a wooden board on the inner ring of the waist bottom, and people walk around on the board to promote the rotation of the garden cover, and the brine after the first sun-drying in the ship-shaped pit of the dam is transported to the heavenly boat through the small bamboo tube on the cover, and then dispersed through the small eye of the long bamboo tube connected from the bottom of the heavenly boat, and then input to the filter cylinder for filtration.

However, the equipment of the cylinder car was abandoned by Su You and the water lifting cylinder was used instead.

The water cylinder is a car water device designed by using an equidistant spiral, made of leather and bamboo tube, which can be driven by wind power, similar to the Archimedes cylinder commonly used in small water conservancy projects in later generations, which is more labor-saving and efficient than the cylinder car.

After the filter cylinder filters out the sediment and impurities contained in the brine that increases the concentration for the first time, it can be used to fry salt in the central and western Sichuan areas.

However, in order to further improve the concentration and save firepower, Su oil creatively introduced the secondary concentration process.

"Splashing the stove and printing the stove", popular in the east of Sichuan in the later generations, is to soak the brine into the mud ball of the salt stove through the splashing of the stove, and increase the concentration through evaporation.

"Yin" is a Sichuan dialect, which has the meaning of watering and infiltration.

This is also a scientific application of heat exchange escape energy, using the stove as a dragon stove, with a long stove chamber with five salt pots on the top, and in the middle and on both sides, there are also fire chambers and fire channels containing earth balls.

When the temperature of the furnace rises to a certain level, the soil balls on both sides are burned hot, and the salt workers pour brine on them while boiling the salt.

The crisp void in the soil ball greatly increases the evaporation area, and the high temperature in the furnace will cause the water to evaporate quickly, while the salt remains inside and outside the soil ball.

The earth balls are piled up in the form of high in the front and low in the back to make it easier for the salt workers to carry the bucket and splash it.

After a period of time, the salt in the soil ball is saturated, and a saline soil is formed.

After the soil ball full of salt is taken out, it is finely broken into small pieces by the processing hammer, and poured into the front pool of the brine pool, and the concentrated brine drawn from the original brine pond is poured on the salt soil, and the brine absorbs the salt in the salt soil, and the concentration is increased again, and the concentrated brine that is close to saturation is prepared.

The concentrated brine flows into the rear pool through a notch or hole. The rear tank is also a secondary filtration and sedimentation tank, and the brine after that is then stored in a large concentrated brine tank through the pipeline.

Suyou is ready to boil salt with honeycomb coal, and the honeycomb coal burns the remaining cinder body, which has the most reasonable evaporation structure, and even saves the effort of making soil balls.

After the brine is drenched, the cinder can be brewed with clean water and can also be turned into a refractory brick material. It's all about being multi-purpose, and there's no waste.

The place where the salt is fried is called the stove room, and it is commonly known as "field fire". The stove room is generally 25 meters long and 15 meters wide, and the structure is a small green tile house with wooden buckets.

The front part of the stove room is the dragon stove for frying salt, two stoves side by side, a total of ten cauldrons, eight in front are salt pots, and two in the back are warm water pots.

A pot of warm water is used to warm the brine to further increase the concentration of the brine, and a salt pot is used to fry into salt.

The temperature of the dragon stove is high before and then low, after sending the concentrated brine to the warm water pot to increase the concentration, the brine will be moved to the front pot in order with the increase of salt, until the first salt pot at the fire door is boiled into salt, which can use the fire to the extreme.

The brine is gradually turned into salt in a salt pan at high temperatures. In order to make the salt white and the particles crystalline, it is necessary to go through the process of removing impurities, that is, adding soap horn and soybean milk to the frying salt. At the same time, the gallbladder can be used to make bean curd, tofu, and treat leather.

In the second half, there are many processes like this, which even Li Laohan doesn't know.

Behind the pot of warm water is a salt kang, which is rectangular and made of slate stones, about eight meters long and two meters wide.

After the salt in the salt pit accumulates to a certain extent, the stove craftsman scoops the salt with moisture into the salt warehouse, filters out the excess water, and then pinches the salt in the warehouse to the kang above the horizontal dispersed flue behind the dragon stove, and uses the remaining heat carried by the smoke exhaust to dry all the water, that is, table salt.

In this way, fuel efficiency is maximized.

Due to the different methods of decocting salt, the salt products of the new salt well are divided into two types: flower salt and ba salt.

Flower salt is a loose grain salt made by crystallization, fishing, washing, and drying; It belongs to the fine product of snow salt.

Ba salt is a lumpy salt made by boiling the brine in the pot, but even so, because of the impurity removal process, the quality is higher than that of Ningxia green salt.

Flower salt is popular with the Song people, and Ba salt is popular with the Erlin Department because it is easy to carry.

At this point, the single-well salt production process was completed.

However, there is a problem, many wellheads are opened in remote places, and the scattered transportation of firewood and coal will increase the transportation cost, so it is better to operate in a large-scale centralized manner.

The solution is to arrange the brine pipeline.

The bamboo tube pipeline that transports brine is connected like a roller coaster, and the longest can stretch for nearly ten miles, and the brine is transported to the salt refining field from each wellhead for unified refining.

This salt field can be said to be the culmination of the wisdom of many ancients in later generations, and when the scale is up, there will be tens of thousands of people working in this area, which is almost a large industrial base in the modern sense, and can be regarded as one of the highest industrial achievements before the machine revolution.

And these people are almost the first batch of skilled workers in the world's history of large-scale industrial bases.

No one can imagine that the blueprint for the layout of a large industrial base is in this crude bamboo-walled thatched hut, with a bright and extinguished fire pit, one old and one young, while gnawing on rough potatoes, chatting and slowly sketching and taking shape.

It was already late at night, and Su You and Yi lay on the bamboo bed, falling into a deep sleep.

Li Laohan covered him with the only quilt at home, and the grandfather planned to stay up all night by the fire.

Li Dazhuan looked at Su You: "How big a heart does the little young master have in his chest?" It's not a family's business, it's ...... This is a big deal that covers the entire Sichuan Gorge and the four roads. ”

Li Lianzhu looked at the fire pond: "What the little young master often tells us is that the self-cultivation Qi family governs the country and the world, and also says that it is up to the top, to get the middle, to take the middle, and to get the bottom." ”

Li Laohan asked softly, "Good baby, what does the young master mean by this?" ”
