[0002] Pulse jet bag filter is a high-efficiency dry dust removal device. When removing dust from the air, if the air humidity is high, the dust on the surface of the filter bag is easily hardened and caked. In this case, it is often necessary to use compressed air to back-blow and beat the filter bag or replace it directly. The existing treatment methods require disassembly of the machine, which is time-consuming and labor-intensive. In addition, manual operation is required in a dusty space, which can easily affect the health of workers. Utility Model Content

[0005] The beneficial effects of this utility model are as follows: the drive motor drives the sliding plate to reciprocate through the slider, which can beat the filter bag body. The vibration motor drives the protective cover to vibrate, and the protective cover transmits the vibration to the sliding plate and the arc plate, thereby driving the filter bag body to vibrate. This method does not require disassembly and does not require manual operation, thus ensuring the efficiency and effect of filter bag dust removal.
[0006] To facilitate the lead screw driving the slider:
[0007] As a further improvement to the above technical solution: the number of lead screws is two, and the two lead screws are connected by a timing belt.
[0008] The beneficial effect of this improvement is that the timing belt can make the two lead screws rotate synchronously, which facilitates the sliding of the slider and the sliding plate.
[0009] To facilitate the sliding plate pushing the arc-shaped plate into contact with the filter bag body:
[0010] As a further improvement to the above technical solution: the sliding plate and the dust collection box are arranged in parallel to each other.
[0011] The beneficial effect of this improvement is that the parallel arrangement allows the sliding plate to slide smoothly under the drive of the lead screw and the slider.
[0012] To facilitate the shrinkage of the curved plate:
[0013] As a further improvement to the above technical solution: the plug-in rod and the sliding plate are connected by a plug-in connection.
[0014] The beneficial effects of this improvement are: the plug-in connection can compress the helical spring by the plug-in rod, thereby reducing the damage to the filter bag body caused by the arc plate and ensuring the normal use of the filter bag body.
[0015] As a further improvement to the above technical solution: a flexible gasket is bonded to the inner side of the arc-shaped plate.
[0016] The beneficial effect of this improvement is that the flexible gasket can effectively reduce the compressive strength of the arc plate on the filter bag body.
[0017] To reduce contamination of the lead screw:
[0018] As a further improvement to the above technical solution: the protective cover and the dust collection box are arranged in parallel to each other.
[0019] The beneficial effect of this improvement is that the parallel arrangement of the protective covers can provide comprehensive and reliable protection for the lead screw.
[0020] To avoid dust accumulation:
[0021] As a further improvement to the above technical solution: the top of the protective cover is inclined.
[0022] The beneficial effect of this improvement is that the inclined protective cover allows dust on the top of the cover to slide off, thereby reducing dust accumulation on the top of the cover.
[0023] To facilitate vibration of the protective cover:
[0024] As a further improvement to the above technical solution: the guide rod and the second helical spring are arranged with their axes coincident.
[0025] The beneficial effects of this improvement are: the vibration motor drives the protective cover to vibrate, and the guide rod, in conjunction with the helical spring, can assist the vibration of the protective cover while also limiting its movement. Attached Figure Description
