Three water-powered mills, three different functions.

The first one connected is the continuous machine-operated bucket invented by Du Yu, Dangyang Hou of the Western Jin Dynasty. "Book of Jin" records, "Today people make waterwheels with axles that can be several feet long and run through horizontal logs, intersecting like spears."

"The water stirs the wheel, and then the crossbars between the shafts hit the tips of the rows of buckets, and they fall together to pound them, which is the machine bucket."

It uses a large water wheel to drive the wheel axle. The wheel axle is equipped with a row of staggered dials. The dials then move the rice milling rod, causing several rice milling heads to continuously pound rice one after another.

Kelongli's machine-operated mill has eight dials on the wheel, corresponding to four mill nests on one side. It can process grain at the same time, and can also be used to grind clay, spices, and ores.

The second mill is connected to a relatively complex machine and water wheel.

This thing was actually invented on the basis of the water wheel soil mill. By changing its shaft head device, it can have the three functions of grinding flour, hulling rice, and grinding rice.

First, there is a large vertical water wheel driven by water power. A gear is installed on the extended axle, and it forms a gear set with two other gears.

The paddle on the shaft can drive the tiller rod to make the tiller head reciprocate up and down to pound rice.

One of the gear sets is a flat wheel, and the shaft where the flat wheel is located is equipped with a grinding wheel. The surface can be ground with a stone grinding wheel. If it is replaced with a soil grinding wheel, the shell can be removed.

It should not be underestimated. It is recorded in "Book of Agriculture": "The three things of a water wheel are called the water wheel axis, which can do three things: grinding, hulling, and grinding. At first, a water mill was set up to turn wheat into flour, as usual;

Make a round trough on the outer circumference of the mill. If you want to harvest rice, just use the head of the water wheel shaft to easily grind and place rice hullers. Once you have obtained rice, remove the rice hullers and place it for grinding. The dry rice mill will be ground along the trough to get mature rice."

"One opportunity and three things are always ready, flexible and able to be connected, comprehensive but not lacking, simple and essential, a living method that is sincere and convenient for the people, and a hidden opportunity for creation."

One machine per day can process three thousand kilograms of rice!

The third mill is Su You's own invention of the oil press.

This thing has never appeared in ancient China because it uses a ball screw that was not available in ancient times.

The screw press has already been used when making mustard, but now there are balls carefully selected with a micrometer. They are added between the screw and the nut, and rolling friction is used instead of sliding friction, and the ordinary screw is transformed into a screw press.

Became a ball screw.

The screw converts rotary motion into linear motion. The outer profile of the nut is gear-shaped, and is rotated by the gear box, causing the screw to move forward or backward in a straight line, pushing the metal tablet to squeeze the material. This is a screw press.

After cleaning, crushing, softening, embryo rolling, steaming, frying, pressing, and filtering the seeds, soybean oil, sesame oil, camellia oil, and mixed oil can be obtained.

It can also be used to press sugar cane or compress powder to make compressed feed and compressed food.

The above are food, and the other one is production materials, very important tung oil.

Compared with stamping, screw pressing is slower, but more precise and stable, so it can also press metals with soft texture and high processing technology, such as exquisite coins.

In Kelong, it is impossible to collect coins, but there is no problem with the exquisite sword tangs, scabbard decorations, and some door and window accessories.

In the sword processing industry, metal decoration is a professional craft, and blade making is two categories.

If the Shi family wants to make huge profits from the Dali sword, of course they have to make great efforts in these aspects.

The children just followed suit. Su You's slogan for the children was that one day, they should be able to use mechanical methods to mass-produce products to the level that only Shijia Seiko can achieve.

Of course, this is pie in the sky, but that doesn’t mean there is no hope at all.

For example, with the emergence of abrasive paste, children can now use wheel belt equipment and abrasive paste to achieve the level of metal surface treatment that Shijia grinders achieved before.

But the problem is that the grinders in Shijia Ironworks also use abrasive paste, and the level of precision work has also gone up. The gap is still a gap, and it is getting wider, but it is difficult for laymen to see it.

With brass with good sealing performance, standard parts of bolts and nuts, micrometers, springs, steel sheets, and water glass precision casting technology...With these various technological and technological advancements, Su You took Liu Sihe

Zhang Sheng came up with something simple but not simple, the butt-type hard-sealed ball valve.

A ball valve is a valve that uses a metal ball with a hole as the opening and closing component, driven by the valve stem, to rotate around the axis of the ball valve.

Its function is to regulate and control fluids.

In fact, it is a key component inside the faucet. However, compared with the industrial mass production of faucets, this thing needs to be finely ground by hand. Because there is no rubber, the steel sealing ring and the brass valve core must be tightly combined to achieve perfection.

sealing effect.

After all, it is still a fitter job. Several team leaders can take the children to complete other tasks, but this key part is not done well. Currently, only Shi Fu is competent.

But with this thing, Suyou is as beautiful as heaven.

Not only are the pig pens, chicken sheds, and greenhouses available, but the first luxury item in Su's house is a washroom and bathroom.

Only then did Su You think about whether it was time to start working on cement.

Industrial production of cement requires a converter, which is almost impossible.

However, in later generations, there were still many small workshops in rural areas that used small vertical kilns to burn cement, using local methods. Like small paper mills, they were among the most severe targets for environmental protection.

There are three types of clay cement that Guangsu Oil knows: slag cement and alumina cement.

Clay cement is the weakest, with clay and broken pottery powder as the main materials.

Slag cement is good, mainly composed of coal ash and ironmaking slag, and the composition of the finished product is close to the formula of ordinary Portland cement.

Aluminum cement is made from bauxite and fragments of scrapped jade porcelain as raw materials, which are crushed and fired. Therefore, the cement produced has certain characteristics of alumina cement, that is, fast solidification and high strength.

For example, cement made entirely from white porcelain fragments is as white as jade and can be used as white cement for decorative joints. However, just like porcelain production, iron contamination during processing must be prevented to prevent the white from turning into red.

The three materials are burned and are called clinker. Lime and gypsum are also added as ingredients to form cement.

Regardless of the production material, there are so many Sitong stores nowadays.

The broken ceramics from Shijia's porcelain workshop, the slag from Shijia's furnace, and the cinders from the mausoleum are almost piled up into a mountain.

In view of this situation, Su You decided that for the environmental protection cause of the Song Dynasty, a cement workshop must be built.

It sounds very ridiculous, but today's natural environment in the Song Dynasty can actually easily dilute the gas and water pollution emitted by Meishan's quasi-industrial industry. Therefore, Meishan's environmental problem is really a waste accumulation problem.

Turning these waste residues into usable things and consuming them can indeed solve most of Meishan's current environmental problems.

There is no room for reasoning.

The advantages of the above three types of cement are good water resistance, good acid and alkali corrosion resistance, easy and simple production, and can be applied to water and underground projects and buildings with acid and alkali corrosion.

But the intensity is low, so there is no need to worry about high-rise buildings.

But pools, fish ponds, bathing ponds, the basic parts of houses...

There are also urinals, septic tanks, toilets, pig pens, pig troughs, livestock troughs, silage tanks, feed tanks, millstones...

In short, it is completely sufficient for today's Kelonli.

Disadvantages include poor frost resistance, slow solidification speed, and prone to dry shrinkage cracks, so maintenance work is very important during use, and the cycle is very long, almost a month.

When pouring beams, columns and slabs, their grades must be determined in advance, and then the concrete should be prepared according to the design strength.

Fortunately, this is in Meishan, and there is also an old artifact called Glauber's Salt.

Dissolve the Glauber's Salt in hot water and mix thoroughly. Then mix the Glauber's Salt solution with the mortar or concrete, which can greatly speed up the solidification speed.

Just do it and get the lab process out first.
