A spring is provided between the front side of the contact plate and the rear side of the connector, and the waste gas containing dust is input into the ash hopper through the air inlet. The large particles of dust in the waste gas fall under the influence of gravity and adhere to the ash hopper, while the small particles of dust float upward into the filter box together with the waste gas. The small particles of dust contact the filter bag and are filtered to the surface of the filter bag, and the filtered gas floats into the clean room through the filter bag and the fixed porous plate, and then is discharged through the exhaust port. At this time, the air inlet and exhaust port are closed, and then the electromagnetic pulse valve is opened. The pulse is sprayed into the clean room and the filter box through the injection pipe. The filter bag is agitated by the pulse, thereby shaking off the dust adhering to its surface.When all the dust falls into the ash hopper, the ash discharger is turned on, and the ash discharger discharges the dust out of the device, opens the cover, and starts the first linear motor. The first linear motor drives the movable seat to move forward or backward, and the movable seat drives the blowing pipe to move. When the movable seat is in contact with the inner wall of the clean room, it stops moving.

The lifting rod is fixedly connected to the lower surface of the movable porous plate by screws, the cross connecting rod is fixedly connected to the bottom end of the lifting rod, and the scraping frame is fixedly connected to one end of the cross connecting rod close to the inner wall of the filter box.

When the movable porous plate rises, it drives the lifting rod to rise, the lifting rod drives the cross connecting rod to rise, the cross connecting rod drives the scraper frame to rise, the scraper frame scrapes the dust adhering to the inner wall of the filter box, and when the scraper frame moves upward, it drives the L-shaped connecting plate to move upward, the L-shaped connecting plate drives the first rotating rod and the second rotating rod to move upward, the first rotating rod and the second rotating rod drive the roller to move upward, the roller contacts the inner wall of the filter box to generate friction and then rolls, the rolling of the roller drives the first rotating rod and the second rotating rod to rotate, and the first rotating rod and the second rotating rod then drive the cleaning roller When the cleaning roller rotates, it contacts the upper surface of the scraper frame and sweeps the dust accumulated on the upper surface of the scraper frame into the ash hopper. When the movable porous plate descends, it drives the cross connecting rod to descend, and the cross connecting rod drives the scraper frame to descend. The scraper frame drives the first rotating rod and the second rotating rod to descend through the L-shaped connecting plate, and the first rotating rod and the second rotating rod drive the roller and the cleaning roller to descend.

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 is affected by gravity and quickly passes through the chip discharge device of the ash discharger. When the cross-link moves downward, it drives the transmission frame downward, and the transmission frame drives the L-shaped transmission rod downward, and the L-shaped transmission rod drives the U-shaped sponge downward and absorbs the water stains on the ash hopper. When the U-shaped sponge moves downward, it is resisted by the inclined surface of the ash hopper, thereby driving the L-shaped transmission rod to extend out of the transmission frame and stretch the elastic telescopic rod, so that the U-shaped sponge can continue to descend to the bottom of the ash hopper. When the cross-link drives the transmission frame to rise, the elastic reset effect of the elastic telescopic rod drives the L-shaped transmission rod to slide and shrink into the transmission frame, so that the U-shaped sponge is always in contact with the inner wall of the ash hopper.

[0025] Working principle: Dust-containing exhaust gas is input into the ash hopper 2 through the air inlet 3. Large dust particles in the exhaust gas fall due to gravity and adhere to the ash hopper 2, while small dust particles float upward into the filter box 1 together with the exhaust 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. At this time, the air inlet 3 and the exhaust port 9 are closed, and then the electromagnetic pulse valve 8 is opened. The pulse is sprayed into the clean room 6 and the filter box 1 through the blowing pipe 103. The filter bag 1011 is affected by the pulse and agitated, thereby shaking off the dust adhering to its surface. When all the dust falls into the ash hopper 2, the ash discharger 4 is opened. The dust discharge device is opened, the cover 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 movable seat 101 is in contact with the inner wall of the clean room 6, it stops moving. At this time, the blowing pipe 103 moves from above the movable porous plate 105 to above the partition 5, and when the movable seat 101 moves, the connecting hose 102 is elastically deformed by the pulling of the movable seat 101. The second linear motor 104 is started. The second linear motor 104 drives the movable porous plate 105 to rise, and the movable porous plate 105 drives the filter bag frame 109 and the filter bag 1011 to rise. When the movable porous plate 105 rises to the top of the clean room 6, the movable porous plate 105 and the second linear motor 104 are connected. The linear motor 104 is disassembled, which makes it convenient for the staff to take out the movable porous plate 105 and the filter bag 1011 for cleaning, thereby improving the convenience of the staff in cleaning the device. After the movable porous plate 105 is taken out of the clean room 6, the staff pulls the pull plate 1017 forward, and the pull plate 1017 drives the slide bar 1014 to slide forward in the connecting piece 1013, and the slide bar 1014 drives the contact plate 1015 to move forward, and the contact plate 1015 drives the card shaft 1016 to move forward and be pulled out from the through hole opened in the trapezoidal card block 1012, so that the card shaft 1016 and the trapezoidal card block 1012 are separated.

After cleaning the filter bag 1011, the filter bag 1011 and the mounting ring 1010 are put on the filter bag frame 109 again and moved upward. The mounting ring 1010 drives the trapezoidal clamping block 1012 to insert into the movable porous plate 105. At this time, the inclined surface of the trapezoidal clamping block 1012 contacts the arc surface of the clamping shaft 1016. The trapezoidal clamping block 1012 pushes the clamping shaft 1016 forward through the guidance of the inclined surface. The clamping shaft 1016 drives the contact plate 1015 to move forward and squeeze the spring. When the mounting ring 1010 and the movable porous plate 105 are fitted together, the through hole on the trapezoidal clamping block 1012 is just aligned with the clamping shaft 1016.At this time, the elastic return effect of the spring drives the clamping shaft 1016 to move backward through the contact plate 1015 and insert it into the through hole to lock the mounting ring 1010 and the movable porous plate 105, thereby quickly completing the installation and further improving the convenience of use of the device.

When the scraper frame 113 moves upward, it drives the L-shaped connecting plate 114 to move upward, and the L-shaped connecting plate 114 drives the first rotating rod 115 and the second rotating rod 116 to move upward, and the first rotating rod 115 and the second rotating rod 116 drive the roller 118 to move upward, and the roller 118 contacts the inner wall of the filter box 1 to generate friction and then rolls, and the roller 118 drives the first rotating rod 115 and the second rotating rod 116 to rotate, and the first rotating rod 115 and the second rotating rod 116 then drive the cleaning roller 117 to rotate When the cleaning roller 117 rotates, it contacts the upper surface of the scraping frame 113 and sweeps the dust accumulated on the upper surface of the scraping frame 113 into the ash hopper 2, thereby improving the cleaning effect of the scraping frame 113. When the movable porous plate 105 descends, it drives the cross connecting rod 112 to descend, and the cross connecting rod 112 drives the scraping frame 113 to descend. The scraping frame 113 drives the first rotating rod 115 and the second rotating rod 116 to descend through the L-shaped connecting plate 114. The first rotating rod 115 and the second rotating rod 116 then drive the roller 118 and the cleaning roller 117 to descend. 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.

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 the 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 and the inner surface of the transmission frame 124 are slidingly connected. The circumferential surface of the U-shaped sponge 127 contacts the inner wall of the ash hopper 2. 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, further improving the cleaning effect of the ash hopper 2.

[0029] 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 then 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 stretching 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, thereby making the U-shaped sponge 127 always fit with the inner wall of the ash hopper 2, further improving the cleaning effect of the ash hopper 2.
