Infrastructure: I survive in troubled times

Chapter 239 Bellows (four more)
"This can be done! But the direction of Xishan is not good. The terrain is high, and there must be a waterwheel to draw water." Cao Huaimin said after thinking seriously.

"Then let's make a waterwheel." Hong Lianshuo smiled and nodded.

"Okay!" Cao Huaimin replied with a smile.

"Are we making shovels and pickaxes all of wood?" Hong Lianshuo asked Cao Huaimin, "Use wood to melt the damaged weapons into molten iron."

"That's right! Why don't you use wood? The way to burn fire is to use wood." Cao Huaimin blinked at her and said, "What are your thoughts on Mrs. Hong?"

"No, no?" Hong Lianshuo shook his head slightly when he heard the words.

Now that there is no coal, it is not so easy to find coal mines, and even if you find coal mines, digging coal is hard work, and you will not be able to dig coal for a while.

Hong Lianshuo's eyes wandered slightly, and suddenly he remembered and said, "Is there any support for burning the fire?"

"Combustion?" Cao Huaimin scratched his head and looked at her puzzled, "Can you be more specific?"

"Is that so?" Hong Lianshuo thought about it seriously and said, "I just don't like the fire, so I blew into the stove's eyes." He pursed his lips and said, "How do you say something." He patted his thigh and smiled, " When I think about it, I don't know anything about blowing fire with a rolling pin!"

Cao Huaimin finally understood, smiled and said, "Now there is no need to blow fire with bamboo pipes. It's like a blacksmith uses a leather bag to blow wind and smelt iron. This kind of leather bag is thin at both ends and bulges in the middle..."

"I know." Hong Lianshuo nodded clearly, "Squeeze."

"Yes, yes!" Cao Huaimin said with a smile.

"Is there nothing else?" Hong Lianshuo asked, looking at him hopefully.

"No." Cao Huaimin looked at her with black eyes and said, "This skin-sac wind has been around since the Spring and Autumn Period and the Warring States Period. It is also known as a windbag made of cowhide; the original refers to the mouth-blown wind instrument, and the blacksmith also called them the loser. Wind pipe. The technology of iron smelting in the Han Dynasty has been greatly developed, which is closely related to the improvement of the power of Chu.”

Hearing this, Hong Lianshuo frowned slightly and said, "This is too tiring! I have to keep squeezing my hands."

Cao Huaimin was stunned when he heard the words, and then smiled, "There are people stepping on it. Besides, I'm used to it, so I can't say I'm tired."

Hong Lianshuo stroked his forehead, this bellows has no pattern, how should grandma's be remodeled?

Wait a minute, bladder blast improvements?Hong Lianshuo looked at Cao Huaimin with a green light in his eyes and said, "Can't this blower be improved?"

"Uh..." Cao Huaimin pursed her lips and said, "I'm not sure about this, I'll draw it for you!" Then he put the water on the small square wooden table, "It has 3 A wooden ring, two circular plates, covered with leather. Open the tuo, the air enters the tuo through the intake valve; compress the tuo, and the air in the tuo enters the air supply pipe through the exhaust valve, And finally into the smelting furnace."

Hong Lianshuo looked at him with sparkling eyes, and the corners of his eyes and brows were full of smiles, which could be improved, "This skin pouch is one-way, can it be changed to two-way?" With his index finger dipped in water, he drew it and said, "And the animal skin pouches It’s hard to find, but it’s made of wood! You can make as many as you want, and you can go to thousands of households.”

Cao Huaimin twisted his beard and stared at the blowing machine she painted, "You are like what Lao Tzu described: between heaven and earth, is it still swaying? It is empty but not yielding, and it is more and more out when it moves."

Hong Lianshuo was stunned for a moment, then nodded hastily, "Mmmm! The more it pushes and pulls, the greater the air volume it gives. Isn't the space between heaven and earth just like a bellows? Although it is empty, it will not be exhausted."

What Hong Lianshuo painted was actually a bellows, a stove made of bricks and a bellows next to it, which was used by every family in later generations for cooking.

After filling the pot with water, light the firewood and put it into the stove mouth, pull the bellows with the right hand, and add the firewood with the left hand.

A bellows consists of a rectangular box with air inlets at each end: when the box is pulled out by hand, air is drawn in from the far side; when it is pushed in, air is drawn in from the near side.In both inward and outward processes, air is drawn into the box; in both cases, the compressed air is pushed into the side chamber, where it is discharged through the exhaust port.

"You can ask a carpenter to make it and try it." Cao Huaimin nodded with a flash of light in his eyes.

"It's better to hurry up, we blacksmiths need it the most, Wen..." Hong Lianshuo slammed on the brakes, swallowed the duo, and pursed his lips, "It's easier to strike iron when the heat is hot."

"I'll go after I draw the pattern." Cao Huaimin said immediately after hearing the words.

"Can't we go now?" Hong Lianshuo looked at him eagerly and said, "Isn't there a pattern like this?"

"You can't be in a hurry! Look at this pattern and it's done." Cao Huaimin looked at her in a hurry with his smiling black eyes. The watermark pattern on the small wooden table had been blown dry by the wind.

"I'm too impatient." Hong Lianshuo smiled embarrassedly.

"I'm also anxious. If it can be as good as we expected, it will be a huge improvement for iron smelting." Cao Huaimin said, "I will focus on doing it as soon as possible Okay, this is so important."

"Hmm!" Hong Lianshuo nodded again and again, "Call me when you're done."

"Let's see the effect together?" Cao Huaimin said with a smile, and bowed to her, "I'm going in to draw a pattern."

"I'll leave without delaying you." Hong Lianshuo cupped his hands, put down his son and left.

"We're leaving too." Han Yanhu and the others stood up and cupped their hands.

Cao Huaimin watched them leave, then turned around and went back to the house, where he continued to draw the house, just waiting for the red bricks to be ready to build the house.

Several kilns are burning bricks day and night, and it should be soon.

"Nan Zheng, I'm talking about ancient times today. I listened to the tail, and I saw that you are quite well-organized. This wooden board has been used." Han Zhuhu looked at him with a smile on his lips and said, "The two sides of Chu and Han above. It's clearly written."

"Hey! Stop talking, this face has already been lost." Lin Nanzheng said embarrassedly, stroking his forehead, and said embarrassingly, "I have never been so embarrassed in my life."

"What's going on?" Chen Zhongyuan looked at him curiously with big copper bell-like eyes and said, "Nanzheng teaches brothers to write, but be patient and teach them well."

"Yeah! After reading and writing this, the brothers memorized a lot of words." Si Xi said with a slobber, "There are very few mistakes, and I eat a lot of chicken thighs."

"Hehe..." Everyone laughed.

Chen Zhongyuan looked at Lin Nanzheng with a puzzled look in his eyes and asked, "What's wrong with talking about the ancients?"

"You are familiar with history books." Han Yanhu tilted his head slightly and looked at him and said briskly, "This shouldn't be difficult for you!"
