[0026] The present application is directed to the existing CN202022169115.7 a coal mine safety ventilation device structure is complex, can't realize the filtration of mine dust, therefore the ventilation filtration effect needs to be improved. The filter plate is installed on the back of the window frame, the filter plate has double-layer dust filtering function, which can effectively filter the influence of mine dust. Figures 6-7As shown, the dust filter plate is used for filtering mine dust, and the dust filter plate is clamped on the back of the window frame. The dust filter plate 5 comprises a plate frame 51 and a dust filter screen embedded in the plate frame. The window frame is provided with clamping plates 6 arranged in an up-down manner. In the embodiment, four clamping plates are arranged. Threaded columns 61 are arranged on the back of the clamping plate. The plate frame is provided with through holes 62, and four through holes are arranged. The threaded columns pass through the through holes and are fixed by fixing nuts 63. The dust filter plate is clamped on the back of the window frame, which does not affect the opening or closing of the louver blades. According to the filtering needs of coal mine dust particles, the dust filter screen is arranged. The dust filter screen comprises a first dust filter screen 52 and a second dust filter screen 53. The first dust filter screen is embedded in the front of the plate frame, and the second dust filter screen is embedded in the back of the plate frame. The first dust filter screen and the second dust filter screen are uniformly arranged with dust filter holes. The diameter of the dust filter holes arranged in the first dust filter screen is greater than the diameter of the dust filter holes arranged in the second dust filter screen. The first dust filter screen is used for filtering larger mine dust, and the second dust filter screen is used for filtering smaller mine dust. The effective filtering of different mine dust is realized, and the dust filter plate can be conveniently disassembled and cleaned.

[0027] Working principle: The mining staff operates the bevel gear transmission mechanism, manually operates the transmission bevel gear to drive the meshed main bevel gear to rotate clockwise or counterclockwise, thereby driving the louver blades to open or close. Since the louver blades are driven by the belts, the louver blades are opened or closed together, and the opening and closing angle is determined, and the transmission bevel gear is locked on the connecting column by the locking nut, so that the transmission bevel gear is rotated and fixed.

[0028] Since the dust filter plate is clamped on the back of the window frame, the mine dust of the opened ventilation can be effectively filtered, and the air mine dust pollution is reduced.

[0029] It should be noted that the above preferred embodiment is only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and it cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application should be covered within the protection scope of the present application.
