Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work fall within the scope of the utility model.

[0022] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a kiln ventilation device of gas uniform distribution, including kiln body 1, ventilation pipe 2 and even division board 3, the outer side of the kiln body 1 is provided with shelter cover 101, the upper side of the kiln body 1 is provided with ventilation pipe 2;

[0023] The shunt pipe 201 of two sides of the ventilation pipe 2 is connected symmetrically, and the bottom of two shunt pipes 201 is connected with kiln body 1 by gas guide pipe 202, the even division board 3 is plugged in the inside of the ventilation pipe 2, and the side of even division board 3 is connected with even division cylinder 301, the side of even division cylinder 301 away from even division board 3 is provided with air inlet fan 302, the outer side of air inlet fan 302 is connected with outer connecting ring 304 by connecting rod 303;

[0024] The outer connecting ring 304 and the kiln body 1 are each connected to a connecting lug 305 on the side adjacent to each other, and a connecting bolt 306 is inserted into the connecting lug 305. The equalizing cylinder 301 is frustum shaped, and the side with the larger opening of the equalizing cylinder 301 is close to the air intake fan 302. The side with the smaller opening of the equalizing cylinder 301 is connected to the equalizing plate 3. The outer connecting ring 304 has symmetrical insertion slots 401 inside, and each of the two insertion slots 401 has an insertion block 402 inserted inside. Both insertion blocks 402 are connected to the outer connecting ring 304 by locking bolts 403. The adjacent side of the two insertion blocks 402 is connected to the air intake protective cover 4.

[0025] In specific implementation, in order to avoid uneven and unstable gas filling into the kiln body 1, when gas is introduced, the air intake fan 302 installed inside the outer connecting ring 304 through the connecting rod 303 is activated. The air intake fan 302 drives the fan blades to rotate, and the outside air is introduced into the equalization cylinder 301 through the air intake protective cover 4. After contacting the equalization cylinder 301 and removing the dust inside the air, it contacts the equalization plate 3 on one side of the equalization cylinder 301 for uniform dispersion. At this time, the gas that has been uniformly dispersed inside the ventilation pipe 2 can be introduced into the kiln body 1 for use through the diversion pipe 201 and the air guide pipe 202.

[0026] The frustum-shaped distribution cylinder 301 increases the contact area with air, thereby improving air handling efficiency. The connecting lug 305 and connecting bolt 306 are used for the installation connection of the outer connecting ring 304 and the kiln body 1. The air inlet protective cover 4 is used to protect the air inlet fan 302 and prevent accidental contact. The insertion slot 401, insertion block 402 and locking bolt 403 are used for the installation connection of the air inlet protective cover 4. This kiln ventilation device with uniform gas distribution can evenly send the outside gas into the kiln body 1 from both sides of the kiln body 1 after dust removal and then evenly distribute it, resulting in better combustion effect.

[0027] See Figure 3 and Figure 4 It is known that a flue duct 5 is connected to the upper side of the kiln body 1. The upper side of the flue duct 5 is connected to the heat exchange cylinder 502 through a connecting pipe 501. The outer side of the heat exchange cylinder 502 is connected to the ventilation pipe 2. The outer side of the connecting pipe 501 is inserted into the ventilation pipe 2.

[0028] In specific implementation, in order to further improve the combustion-supporting effect of air and improve the utilization of the temperature inside the kiln body 1, the heat exchange cylinder 502 and the connecting pipe 501 are installed inside the ventilation pipe 2. In use, the gas discharged from the inside of the kiln body 1 is sequentially introduced into the connecting pipe 501 and the heat exchange cylinder 502 inside the ventilation pipe 2 through the smoke exhaust cylinder 5. At this time, the heat of the gas is conducted to the inside of the ventilation pipe 2 through the connecting pipe 501 and the heat exchange cylinder 502, preheats the gas entering the inside of the ventilation pipe 2, improves the activity of oxygen molecules in the gas, and then sends the preheated gas into the inside of the kiln body 1 through the shunt pipe 201 and the air guide pipe 202 for combustion-supporting. The gas uniformly distributed kiln ventilation device can preheat the air outside and then introduce it into the inside of the kiln body 1 for use, which can further enhance the combustion-supporting effect.

[0029] In summary, when the gas uniformly distributed kiln ventilation device is used, the air inlet fan 302 is started to drive the fan blades to rotate, the air outside is introduced into the inside of the uniform distribution cylinder 301 through the air inlet protective cover 4, contacts the uniform distribution cylinder 301, contacts the uniform distribution plate 3 after removing the dust in the air, is uniformly dispersed, exchanges heat with the flue gas discharged from the inside of the connecting pipe 501 and the heat exchange cylinder 502, and is introduced into the inside of the kiln body 1 through the shunt pipe 201 and the air guide pipe 202 for use.
