The working principle of the invention is as follows: when the cleaning device is used, firstly, the exhaust fan 12 is started, waste generated during garbage incineration is led into the dust removal box 1 through the air inlet pipe 5, large-particle dust falls due to gravity before entering the dust removal box 1 and is gathered at the dust collection hopper 2, small-particle dust passes through the dust collection filter bag 7 along with exhaust gas, under the action of the dust collection filter bag 7, the dust is blocked outside the dust collection filter bag 7, gas passes through the dust collection filter bag 7 and enters the cleaning box 4, at the moment, under the action of the exhaust fan 12, the exhaust port 1003 of the cleaning device 10 drives the rotary pipe 1004 and the filter plate 1005 in the cleaning chamber to rotate due to negative pressure, the rotating filter plate 1005 is in contact with the exhaust gas entering the cleaning box 1001 through the air inlet 1002, at the moment, toxic and harmful gas in the exhaust gas is absorbed by the filter plate 1005, the exhaust gas absorbed by the exhaust fan 12, when the filter plate 1005 rotates to the upper side of the cleaning tank 1006, the filter plate 1005 is under the action of gravity, and is not limited by the diameter of the cleaning chamber, the sliding plate 53, the sliding groove 52, so that the sliding plate 53 extends, the whole cleaning device can be led into the cleaning tank 1006, when the sliding plate 1006 is extended and the cleaning tank 1006, the cleaning tank 1006 is easily drawn into the 10053, and the 10053, the cleaning tank 1006, the 10053, the 100cleaning tank 1006 is easily carried out, the 10053, the 10021, the 100cleaning tank 1006 is easily, the 10053, the 10021 is easily absorbed by the cleaning tank, the sliding plate 1006, the cleaning tank, the 1002, the 10021, the 1002, the 10021, at this time, the length of the filter plate 1005 is restored to the original shape, and the filter plate 1005 is repeatedly used, and each time the filter plate 1005 adsorbs and filters the toxic and harmful gas in the exhaust gas, the filter plate 1005 is a clean cleaning liquid, so that the adsorption and filtration effects on the toxic and harmful gas in the exhaust gas are better;
when more dust adheres to the outer side of the dust removal filter bag 7, the dust removal filter bag 7 needs to be cleaned, at the moment, the controller is used for controlling the pulse valve to be opened, so that high-pressure gas in the high-pressure gas tank 601 enters the dust removal filter bag 7 under the action of the ash removal pipeline 602 and the pulse pipeline 603, at the moment, the gas pressure in the dust removal filter bag 7 is instantly increased, and the dust on the outer side of the dust removal filter bag 7 is cleaned while the dust removal filter bag 7 expands;
at the moment, when the pulse gas reaches the bottom end of the dust removal filter bag 7, the gas quantity and the flow rate of the pulse gas are obviously reduced compared with other parts of the dust removal filter bag 7, and at the moment, the pulse gas can drive the vibration device at the bottom to enable the vibration device at the bottom of the bag cage 8 to vibrate and clean dust at the bottom of the dust removal filter bag 7, so that the dust at the bottom of the dust removal filter bag 7 can also be cleaned;
in the first embodiment, the pulse gas drives the vibration plate 94 to vibrate, the vibration plate 94 which vibrates collides with the bottom of the dust removal filter bag 7, and further cleans dust adhered to the bottom of the dust removal filter bag 7, and meanwhile, the first shaking spring 92 is continuously shaken, so that the first shaking spring 92 is continuously converted between elastic potential energy and kinetic energy, the number of times of collision between the vibration plate 94 and the dust removal filter bag 7 is increased, and the dust cleaning effect is improved;
in the second embodiment, the first gas gathering hopper 901 is used for gathering pulse gas, at this time, the gathered pulse gas enters the interior of the vibration hammer 904 through the first gas outlet pipe 902, so that the vibration hammer 904 vibrates and collides with the bottom of the dedusting filter bag 7, and the effect of vibration dedusting is achieved, meanwhile, under the action of the second shaking spring 906, continuous conversion between elastic potential energy and kinetic energy can be performed, the number of times of collision between the vibration hammer 904 and the dedusting filter bag 7 is increased, and the dust removal effect is improved;
in the third embodiment, the second gas gathering hopper 9-1 is used for gathering pulse gas, at the moment, the gathered pulse gas enters the interior of the vibrating rubber ball 9-3 through the second gas outlet pipe 9-2, so that the vibrating rubber ball 9-3 expands, the expanded vibrating rubber ball 9-3 is in contact with the bottom of the dust removal filter bag 7 and supports the bottom of the dust removal filter bag 7, at the moment, the bottom of the dust removal filter bag 7 is under the action of larger tension, dust is cleaned, and meanwhile, gas can be blown out of the dust removal filter bag 7 through the arranged second gas blowing holes 9-4, so that the cleaning effect on the dust at the bottom of the dust removal filter bag 7 is improved;
finally, the dust removed by the dust collector is collected at the dust collection hopper 2 and discharged through the dust discharge port 3.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
