I really don't want to be a rebel [infrastructure]

Cheng Jingwei didn't expect that Luo Shixing had already thought so long-term, and started planning to make money from the rich households in Beidai County!

He couldn't laugh or cry and said, "How much money do those people have?"

Luo Shixing tried hard to persuade: "Lack of money is money. You can't stop making money just because they have less money. They don't have much money, and we don't have any money!"

Speaking of this, Luo Shixing felt a little sad. It seemed that the two of them were living a prosperous life, but one could count that most of the things they had were basic living supplies!

He didn't have any money at all, not to mention deposits, he didn't even have pocket money, and he had to barter to buy anything. Although the local customs were like this, Luo Shixing always felt a little uneasy.

What's more, even if they have some supplies now, these are at most enough to meet their basic living needs, and they can barely maintain food and clothing. Luo Shixing will even plan the New Year's goods from now on, or they won't have enough for the New Year by accident. It's miserable to think about food for New Year's Eve dinner!

The more detailed counting is even more sad: the clothes are sent by Alezhen, the food is given by Alezhen, and the house is built for them by Alezhen sent slaves.

Once Ale really takes these back, the two of them...of course they won't starve to death, but they don't have the current living conditions either.

Hey, Mao Mao is anxious, and Cheng Jingwei still doesn't understand Mao Mao's anxiety!

Cheng Jingwei was keenly aware of Luo Shixing's uneasiness, and found that this uneasiness came from Ale's true attitude. He was immediately relieved, it's okay, the little lynx is not too stupid, and he didn't naively think that Ale would really supply them unconditionally all the time .

Alezhen's kindness to them now requires them to repay, and even wants them to repay more.

In fact, it's not that he can't make money, it's just that the basic conditions have not been met yet, but since Luo Shixing has this idea, let him go.

Cheng Jingwei hurriedly said: "It's because I didn't think carefully. You can do whatever you want, but do you want to fire more mud bricks? Will it be enough?"

Luo Shixing said: "Let's take a look after I finish the calculation, I guess it won't be too much difference."

Even though he said he could do it in one step, he didn't plan to build a brick kiln that was too big. How many people are there in the whole Beidai County, and how many people can afford bricks?

If it is too big, it will waste manpower and material resources. What's more, if you need more in the future, you should find a place to build it. Anyway, there is plenty of open space. With the first experience, it is not very difficult to build again, but the only need to build more brick kilns The entanglement is probably the fuel problem.

I'll talk about this later. According to the dense vegetation, there will be no problem for a while. If it doesn't work, just remember to cut down the tree and replant it.

After Cheng Jingwei heard this, he stopped talking and told Luo Shixing not to run around and left.

Luo Shixing made a face at his figure, this guy still treats him like a child!

After he finished making faces, he continued to write and draw on a clay tablet.

There are actually many types of brick kilns, such as tunnel kilns, air-drying rotary kilns, artificial drying chamber rotary kilns, multi-channel rotary kilns, straight-line rotary kilns, single-channel rotary kilns, and Luo Shixing. The most advanced before but not many. mobile tunnel brick kiln.

Each of these brick kilns has its own characteristics. Among them, the air-drying rotary kiln has always been used more, because the requirements for various values ​​are relatively low, that is to say, as long as the technical content required for this kind of kiln is not high, but there are also brick kilns. A very big disadvantage is that it is greatly affected by the climate. It is basically impossible to produce bricks in the rainy season, and the required drying area is too large.

These two shortcomings have already made Luo Shixing give up this kind of brick kiln. There is a dry season and a rainy season in Jiaozhou, and the rainy season will last for a long time. When the rainy season comes, the brick kiln will shut down.

What's more, the required drying space is still very large. They do not lack space, but there are many animals in the mountains. If the bricks need to be dried in the open air, manual guards are needed. If the guards are not in place, the batch of bricks may be destroyed.

So this is not acceptable, and the artificial drying room rotary kiln performs drying and roasting separately. This is an advanced version of the air-drying rotary kiln. Because it is dried in a drying room, production can also be carried out during the rainy season, but The problem is that the moisture drainage layout of the drying room is very critical. Once the layout is not good, the drying room will not achieve the effect, but it is prone to problems.

But most of the time in Jiaozhou, the air is humid and dehumidified... This is too difficult, give up!

The remaining brick kilns also have their own shortcomings, or they have requirements for the hardness and water content of the bricks. This is a single-channel rotary kiln.

Otherwise, Luo Shixing only knows the name but has not seen the corresponding information. This is a straight wheel kiln.

In fact, the straight rotary kiln is said to be the simplest in structure, but the problem is that when Luo Shixing looked at the relevant materials back then, he only mentioned this part in one sentence, unlike other rotary kilns who analyzed the difficulty of construction and their advantages and disadvantages.

So he really doesn't know how to do this, and there is no time for him to study it now, so he can only build one he knows.

As for the mobile tunnel kiln, don’t even think about it. That kind of kiln is to let the brick kiln move without moving the tunnel car, in order to save the cost of the kiln car, which is basically impossible to realize now.

So Luo Shixing finally decided to build a tunnel kiln, which is like an assembly line factory for later generations.

The opening is responsible for sending bricks into the kiln, and then there is a pre-tropical zone with a lower temperature in front, and the dry bricks are first placed in the pre-tropical zone for firing for a period of time.

Among them, the pre-tropical zone also needs to design the smoke exhaust pipes and chimneys, followed by the firing zone behind. What this place needs is good air transportation.

If it is directly made into a closed space, the fuel lacks oxygen and is prone to insufficient combustion, so the temperature will not increase.

Therefore, this place needs to set up the delivery port for the first air delivery. Since it is the first air delivery, there will be a second delivery of air.

However, the delivery port for the second air supply is between the outlet of the cooling zone at the back. There are openings on both sides of the brick kiln to deliver air, so that the air forms convection and will run to the firing zone.

Then there is the exit of the kiln car. After the bricks go out from the exit, they are finished products.

Simply put, a long factory building is divided into three parts.

After the division, the next thing to pay attention to is the arrangement of the combustion device. Generally, there are three types of combustion devices, top heating, bottom heating and side heating.

Generally, side heating is more commonly used, and both top and bottom require more troublesome production methods.

Luo Shixing naturally chose the simplest one. The heating method on the side means that the width of the brick kiln has to be expanded, because in addition to side heating, there is also a place for the kiln car.

The kiln car needs rails, because no one will control the kiln car from entering to exiting. The temperature inside the brick kiln is more than 1000 degrees. I am afraid that it will directly turn into water vapor when people enter, except for cooling the kiln. Luo Shixing didn't intend to let anyone get too close to the brick kiln.

In this case, if there is no rail kiln car, there is no way to enter and exit smoothly.

It's just that the setting of this track is also a bit troublesome. At the beginning, his mind was all in the form of train tracks.

But the problem is that they don't have that much metal. Luo Shixing made a special inspection when he went to Beidai County before, and found that there are not many metal products in the entire county, and most of the frames are all made of wood.

Obviously, this is due to the local smelting level. As for the local mining of metals, he has never learned about it and does not know.

In fact, there are many mountains here, and there should be rich mineral resources, but I don't know if they can be mined.

Of course, whether the mining is good or not is not something that Luo Shixing needs to worry about now, because even if the mining is good, he can't really mine and smelt it now!

For the matter of the track, he was really worried from the beginning to the end, until Cheng Jingwei came back, he was still thinking about how to make the track.

Do you want to use mud?But the mud is not strong enough. The top of the kiln car is full of bricks, so it must be very heavy. If the mud falls down a few times, the track inside will fail.

If there is a problem with the track, the brick kiln needs to stop the fire and wait for the inside to cool down before going in for repairs.

However, once the fire in the brick kiln is stopped, the loss will be too great. It is equivalent to re-burning the temperature inside the brick kiln from the natural temperature after the repair, which will waste a lot of fuel. Classes require manpower.

When Cheng Jingwei came back, he saw the little lynx sitting on a small bamboo chair, with his legs dangling, and his chin resting on the table, frowning with an unhappy look on his face.

He went over to look at the tablet and asked, "What is this? Are you in trouble?"

When Luo Shixing faced Wei Siwen and A Lezhen, he still had the feeling of these stupid adults, but when facing Cheng Jingwei, he never had the kind of contempt that occurred because the other party's knowledge was not as good as his.

He turned his head, looked at Cheng Jingwei with his head resting on one hand, and explained the problems he had encountered so far.

After hearing this, Cheng Jingwei was a little surprised: "The track that protrudes from the ground? Where did you see this kind of track? Why do you use this kind of track?"

Luo Shixing was slightly taken aback: "Huh?"

Cheng Jingwei said: "Do you want to follow the track of the Qin Dynasty?"

Luo Shixing thought about it for a while before he remembered that in the Qin Dynasty, there had actually been tracks similar to railroad tracks, but at that time such tracks were all made of wood.

However, it is impossible to use wood in a brick kiln. The temperature inside is so high that any wood that goes in will be burned into carbon.

After Cheng Jingwei found out, he also sat next to Luo Shixing and said, "Then what kind of sunken track should we use?"

Sag track?Luo Shixing looked puzzled, and Cheng Jingwei simply drew two lines on the clay board and said, "I think so, and then the wheels are placed within this track."

Anyway, what they need is that the kiln car does not run off-track, and they don't require the track to look good, and it doesn't matter what form it is.

Luo Shixing realized in an instant that the track Cheng Jingwei said was more similar to the track used in later generations of furniture. The wheels were on the door panel, while the track grooves were on the cabinet body, and the wheels were always placed in it to roll back and forth.

This... seems like I can really try it.

Luo Shixing happily blew a kiss to Cheng Jingwei and said, "We Ah Wei are so smart, I even forgot about this, okay, this is solved!"

Although his actions were relatively bold, Cheng Jingwei was still relatively calm.

After all, the atmosphere of Datang is open, and both of them are boys.

Luo Shixing is easy to go crazy when he is happy, he is used to it.

After Luo Shixing recorded the track on the clay board, Cheng Jingwei asked suspiciously: "In this case, no one can enter the brick kiln, how can the car enter?"

Luo Shixing simply said: "Make a special kiln car, and the buckets are connected. At the entrance and exit, people are arranged to push in, and at the exit, people are arranged to drag it out."

In this way, the two places are exerting force, and the cars inside are linked, so they will naturally go out one by one.

It was the only solution he could think of.

In the later generations, most of the solutions are actually solved by machines. For example, the flue has an exhaust fan, and the air inlet has a blower, and then the kiln car inside is automatically moved in and out at a set time.

However, Luo Shixing doesn't have any of them now, so he can only replace them with manpower.

Therefore, the tunnel kiln he involved is actually slightly smaller than the tunnel kiln of later generations. Firstly, it does not require such a large output, and secondly, it is necessary to consider whether human carts will not work.

Cheng Jingwei sat beside him and read what he wrote with interest, and Luo Shixing said without raising his head: "Those are just superficial things, and I haven't counted a lot of data."

Cheng Jingwei imitated his appearance and asked, "What is it?"

Luo Shixing pointed at the schematic diagram above and said: "For example, the effective height, the length of the tunnel and the length of each belt, these must be calculated."

Cheng Jingwei asked curiously: "I can understand other things, what is this effective height?"

Luo Shixing said: "This refers to the maximum height from the platform plane to the inner lining of the vault."

Cheng Jingwei asked casually: "Does this also require precise calculation?"

Luo Shixing nodded seriously and said, "Of course, this involves the efficiency of the brick kiln and the demand for internal combustion fuel."

Then Cheng Jingwei saw that Luo Shixing had written a bunch of categories on the clay board, such as the size of the section, the structure of the kiln roof, and the structure of the kiln wall, all of which were left blank.

Cheng Jingwei felt dizzy just looking at it for a while, and Luo Shixing needed more accurate calculations besides these.

He looked at it and suddenly asked, "What word did you write? It looks so strange."

When speaking, Cheng Jingwei was a little hesitant, because those things didn't look like words at all, but Luo Shixing's writing was so smooth, it looked like the kind he used often, and Cheng Jingwei wondered if it was because he was good at reading. Not enough, so I haven't seen it.

Luo Shixing slapped Cheng Jingwei irritably when his thoughts were interrupted: "Hey, don't make trouble for now, wait until I finish this calculation."

Cheng Jingwei wasn't angry either, just sat beside him and waited quietly, and then he wrote more fancy symbols that surprised Cheng Jingwei.

After he finished writing, Cheng Jingwei asked Cheng Jingwei to repeat the question just now.

After hearing this, Luo Shixing looked at the symbols of addition, subtraction, multiplication, and division as well as Arabic numerals on the clay tablet, and fell into deep thought.

This... how should he explain it?
