The setting of the hexagonal knob 18 can be controlled to rotate by a wrench.

[0028] A choke blade 11 is fixedly connected to the choke shaft 10. The worm groove 17 on the transmission shaft 13 and the worm wheel 14 can realize the rotation of the choke shaft 10, and then realize the adjustment of the angle of the choke blade 11, and realize the control of the air outlet angle. A plurality of load-bearing columns 12 for support are arranged between adjacent choke shafts 10. The load-bearing columns 12 are flush with the upper surface of the circular frame 9, which can realize the flow of people and the transportation of goods above.

[0032] When the present invention is in use, the exhaust system provides a wind source through a high-power blower 5 arranged on a wall panel 2 on one side of the factory building. The high-power blower 5 will transport the wind force on the outside of the factory building into the factory building, and transport the air from the air outlet 3 arranged on the bottom plate 1. The wind force will be transported upward from the cover plate assembly arranged at the opening above the air outlet duct 3, so that the wind force can directly carry out the excess heat generated by the internal combustion engine from bottom to top quickly, which is in line with the heat overflow process, thereby preventing the heat from being retained in the factory building for a long time and causing the temperature in the factory building to rise. Moreover, the entire factory building can be arranged in this way to achieve rapid heat dissipation in multiple positions of the factory building. Compared with the existing horizontal heat dissipation, heat dissipation from all sides can achieve a faster and more effective heat dissipation effect.

The worm groove 17 on the transmission shaft 13 and the worm wheel disc 14 will realize the rotation of the choke shaft 10, and then the angle of the choke blade 11 can be adjusted to realize the control of the air outlet angle, so that the two air outlet channels 3 can simultaneously centrally supply air to the heat source for heat dissipation, so that it can evaporate quickly upwards, avoiding heat drift and causing the temperature of the factory to rise;

[0034] The coal in the plant that uses coal to generate electricity is very easy to fall to the ground. The design of the present invention makes the ground consist of a hollow cover plate, so that the coal that falls on the ground will fall into the air outlet channel, and the inclined air outlet channel 3 can be used to collect the coal that falls inside. The coal will fall on the transmission belt 21, and the inclined scraping inclined plate 22 on the transmission belt 21 will effectively prevent the wind from driving the coal to move. The coal will move between the two scraping inclined plates 22 under the action of gravity, and the wind will not affect the coal, avoiding pollution of the plant air. After collection, the driving motor 20 can be used to control the rotating shaft 19 to realize the movement of the transmission belt 21. The transmission belt 21 will realize the transportation of the coal on it to the side of the collection vehicle 25 during the movement, thereby achieving the effect of coal collection.
