[0018] Example

[0019] This embodiment provides a mine air door through the wall belt control air leakage device, please refer to Figure 1 , as follows:

[0020] The air leakage control device includes: a windshield frame 2, which is fixedly installed on both sides of the wind wall by expansion bolts 7, an upper notch 21 is opened on the upper side of the windshield frame 2, and a lower notch 22 is opened on the lower side of the windshield frame 2; an arc-shaped windshield plate 1, which is fixedly installed on the windshield frame 2 by hinges 8 and the arc-shaped windshield plate 1 covers the upper notch 21 of the windshield frame 2; a straight roller 3, which is installed below the lower notch 22 of the windshield frame 2, and a lower conveyor belt 4 is installed on the straight roller 3; a U-shaped roller 5, which is installed below the upper notch 21 of the windshield frame 2, and an upper conveyor belt 9 is installed on the U-shaped roller 5.

[0021] Furthermore, the windshield frame 2 is formed by welding a combination of channel steel and steel plates.

[0022] Furthermore, the upper notch 21 of the windshield frame 2 is in a U-shaped structure and the lower notch 22 of the windshield frame 2 is in a rectangular structure.

[0023] Furthermore, a flame-retardant belt windshield curtain is provided around the arc-shaped windshield.

[0024] Specifically, the windshield frame 2 of the utility model is fixedly installed on both sides of the wind wall by expansion bolts 7, and an upper notch 21 (gangue passage) and a lower notch 22 are respectively opened on the windshield frame 2. A curved windshield plate 1 is provided on the windshield frame 2, which is made of steel plate cut according to a certain size. The curved windshield plate 1 is fixedly installed on the windshield frame 2 by hinges 8, and the curved windshield plate 1 covers the upper notch 21 on the windshield frame 2. Channel steels are provided on the windshield frame 2 at the left and right ends of the curved windshield plate 1, so that the curved windshield plate 1 can only be flipped outward; the curved windshield plate 1 is adapted to the curvature of the upper belt surface of the upper conveyor belt 9, and a flame-retardant belt windshield curtain 6 is arranged around the curved windshield plate 1 to further reduce air leakage, and the upper belt surface of the upper conveyor belt 9 passes through the space on the lower side of the curved windshield plate 1;

[0025] A U-shaped roller 5 is fixedly installed on the lower surface of the upper conveyor belt 9. By setting the U-shaped roller 5, the lower surface of the upper conveyor belt 9 can smoothly pass through the upper notch 21. The U-shaped roller 5 can be fixed to the device through a support plate, or a separate support frame can be provided;

[0026] When the gangue is transported out from the upper slot 21, the arc-shaped wind shield 1 automatically opens; when there is no gangue to be transported, the arc-shaped wind shield 1 automatically falls down, closing the gangue channel in time to block the wind flow, thereby effectively controlling the air leakage. In the early stage, the wind curtain modified from the old flame-retardant belt was used to control the wind, and the air leakage reached 1100m 3 / min, resulting in serious waste of fresh air flow; after processing and manufacturing the air door through-wall belt control air leakage device, the air leakage volume was reduced to 280m 3 / min, greatly reducing the air leakage in the mine.

[0027] A lower notch 22 for the lower conveyor belt 4 to pass through is provided below the windshield frame 2. The straight roller 3 is located on the lower side of the lower belt surface of the lower conveyor belt 4. The straight roller 3 can be fixed to the device through a support plate, or a support frame can be provided separately. By providing the straight roller 3, the lower belt surface of the lower conveyor belt 4 can pass through the lower belt space straightly to reduce wear. In this way, the belt space can also be designed to be smaller in size, further reducing air leakage. The air leakage of the belt wall hole can be effectively controlled and reduced to ensure that the ventilation system is stable and reliable.
