When the filter bag is in an air-wet environment, dust is adhered to the surface of the filter bag 201 and hardened due to moisture, when the filter bag is difficult to clean only by pulse airflow, the gravity sensor 102 recognizes the gravity change of the filter bag frame 2, when the fact that the gravity increased by the hardening of the dust of the filter bag frame 2 exceeds a normal range is recognized, the gravity sensor 102 regulates the extending distance of the electric push rod 103, the electric push rod 103 drives the push block 104 to descend, the inclined surface of the outer wall of the push block 104 is tightly attached to the vibration plate 405, the vibration plate 405 is pressed when the push block 104 descends, the position of the vibration plate 405 is regulated, then a motor is started to drive the threaded rod 4 to rotate, the threaded rod 4 drives the movable seat 401 to vertically move in the rotating process, the two cleaning plates 402 slidably arranged on the outer wall of the movable seat 401 synchronously move downwards, the cleaning plates 402 are tightly attached to the outer wall of the vibration plate 405 in a wave design, and simultaneously continuously press the second spring 403, the cleaning plates 402 reciprocate in the horizontal direction under the action of the elastic force of the second spring 403, and the brush 402 mounted on the inner wall of the mouth 404 moves along with the cleaning plates 402, so that the filter bag 201 is cleaned up again, and the filter bag 201 is cleaned in a good state and has good ventilation performance;
when the threaded rod 4 rotates, the second rotating disc 503 installed at the bottom end of the threaded rod rotates synchronously, the rotating block 504 is installed at the edge of the outer wall of the second rotating disc 503, the rotating block 504 is rotationally connected with the dust-proof baffle 5, when the rotating block 504 moves circumferentially along with the second rotating disc 503, the dust-proof baffle 5 is pushed to vibrate in the inner cavity of the limiting plate 501, the shaken-off dust can be more smoothly led into the dust-collecting hopper 101, the dust collecting efficiency is improved, the inclined dust-proof baffle 5 can shield pulse airflow in the vibration process, the possibility that the pulse airflow rushes into the dust-collecting hopper 101 to cause secondary dust emission is reduced, and the integral dust-collecting effect of the dust remover 1 is improved.
In the description of the present invention, unless otherwise indicated, the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", etc., refer to the orientation or positional relationship as indicated on the drawings, which are well known to those skilled in the art, merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. In the description of the present invention, unless explicitly stated and limited otherwise, the terms "connected" and "connected" are to be construed broadly, and for example, they may be fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
