[0002] The dust removal device usually has a relatively fixed air inlet port, which remains unchanged after the equipment is installed. In order to ensure effective dust filtration, the dust removal device itself is designed to have a certain thickness. With the passage of time, the filter near the air inlet port will gradually be clogged due to rapid dust accumulation, and the pores will be filled with a large amount of dust, which directly leads to a significant decrease in filtration efficiency. The filter that can efficiently intercept dust particles is partially clogged, which greatly reduces the overall filtration effect of the dust removal device on air dust. The filter cannot continuously, stably and comprehensively filter the incoming air with high quality, so the entire filter needs to be replaced in advance, causing great waste of resources. Moreover, when replacing the filter, the existing heating and dust removal device needs to be disassembled before the corresponding operation can be performed. During the disassembly period, the ventilation device loses its dust filtration function and cannot continue to purify the incoming air, thereby failing to ensure the ventilation quality. SUMMARY

[0005] Among them, the top end of the rotation rod is fixedly connected with a top plate, and the dust removal pad is attached to the inner wall of the ventilation box.

[0006] Among them, the front slide plate is fixedly connected with a support frame on one side, and a push plate is slidably connected between the front slide plate and the support frame. One end of the push plate is fixedly connected with an adjusting rod, and the adjusting rod is slidably connected with the back slide plate.
