The cleaning liquid quickly absorbs the dust adhering to the ash hopper, and then the ash discharger is turned on. The cleaning liquid mixed with the dust quickly passes through the chip discharge device of the ash discharger under the influence of gravity. When the cross-link moves downward, it drives the transmission frame downward, and the transmission frame drives the L-shaped transmission rod downward. The L-shaped transmission rod then drives the U-shaped sponge downward and absorbs the water stains on the ash hopper.

The large dust particles in the waste gas fall due to gravity and adhere to the ash hopper 2, while the small dust particles float upward into the filter box 1 together with the waste gas. The small dust particles come into contact with the filter bag 1011 and are filtered to the surface of the filter bag. The filtered gas floats into the clean room 6 through the filter bag 1011 and the fixed porous plate 106, and then is discharged from the device through the exhaust port 9.

The pulse is sprayed into the clean room 6 and the filter box 1 through the injection pipe 103. The filter bag 1011 is agitated by the pulse, thereby shaking off the dust adhering to its surface. After all the dust falls into the ash hopper 2, the ash discharger 4 is opened. The dust discharge device is opened, the cover plate 7 is started, and the first linear motor 10 is started. The first linear motor 10 drives the movable seat 101 to move forward or backward, and the movable seat 101 drives the blowing pipe 103 to move.

When the roller 118 descends, it still contacts and rolls with the inner wall of the filter box 1, thereby driving the cleaning roller 117 to rotate again through the first rotating rod 115 and the second rotating rod 116. When the cleaning roller 117 rotates, it contacts the inner wall of the filter box 1 and sweeps away the dust that the scraping frame 113 has not been completely scraped off, thereby further improving the cleaning effect.

[0018] See also Figure 1-Figure 10On the basis of the above embodiment, in another embodiment of the present invention, the rapid ash discharge device 12 includes a fixed plate 121, a water pump 122, and an atomizing nozzle 123. The fixed plate 121 is fixedly connected to the right side of the filter box 1, the water pump 122 is fixedly connected to the upper surface of the fixed plate 121, and the atomizing nozzle 123 is fixedly connected to the left side of the water pump 122. The cleaning liquid quickly absorbs the dust adhering to the ash hopper 2, and then the ash discharger 4 is turned on. The cleaning liquid mixed with the dust is quickly discharged from the device through the ash discharger 4 under the influence of gravity, thereby improving the ash discharge efficiency of the device. The rapid ash discharge device 12 also includes a transmission frame 124, an elastic telescopic rod 125, an L-shaped transmission rod 126, and a U-shaped sponge 127. The transmission frame 124 is fixedly connected to the lower side of the cross connecting rod 112 The surface, the elastic telescopic rod 125 is fixedly connected to the inner surface of the transmission frame 124, the L-shaped transmission rod 126 is fixedly connected to one end of the elastic telescopic rod 125 close to the lifting rod 111, and the U-shaped sponge 127 is fixedly connected to the bottom end of the L-shaped transmission rod 126. The atomizing nozzle 123 penetrates into the interior of the filter box 1 from the right side of the filter box 1, and the L-shaped transmission rod 126 is slidably connected to the inner surface of the transmission frame 124. The circumferential surface of the U-shaped sponge 127 contacts the inner wall of the ash hopper 2, and the U-shaped sponge 127 moves downward and absorbs the water stains on the ash hopper 2, thereby improving the cleaning effect of the ash hopper 2. The L-shaped transmission rod 126 slides and shrinks into the transmission frame 124, so that the U-shaped sponge 127 is always in contact with the inner wall of the ash hopper 2, thereby further improving the cleaning effect of the ash hopper 2.

[0019] Working principle: After the gas is discharged from the clean room 6, the water pump 122 is started, and the water pump 122 draws the cleaning liquid into the atomizing nozzle 123, and the atomizing nozzle 123 sprays the cleaning liquid to the bottom of the filter box 1 and the ash hopper 2. The cleaning liquid quickly absorbs the dust adhering to the ash hopper 2, and then the ash discharger 4 is turned on. The cleaning liquid mixed with the dust is quickly discharged from the device through the ash discharger 4 under the influence of gravity, which improves the ash discharge efficiency of the device. When the cross link 112 moves downward, it drives the transmission frame 124 to move downward, and the transmission frame 124 drives the L-shaped transmission rod 126 to move downward, and the L-shaped transmission rod 126 drives the U-shaped sponge 127 to move downward. The U-shaped sponge 127 moves and absorbs the water stains on the ash hopper 2, thereby improving the cleaning effect of the ash hopper 2. When the U-shaped sponge 127 moves downward, it is resisted by the inclined surface of the ash hopper 2, thereby driving the L-shaped transmission rod 126 to extend out of the transmission frame 124 and stretch the elastic telescopic rod 125, so that the U-shaped sponge 127 can continue to descend to the bottom of the ash hopper 2. When the cross connecting rod 112 drives the transmission frame 124 to rise, the elastic reset effect of the elastic telescopic rod 125 drives the L-shaped transmission rod 126 to slide and shrink into the transmission frame 124, so that the U-shaped sponge 127 is always in contact with the inner wall of the ash hopper 2, further improving the cleaning effect of the ash hopper 2.
