[0021] The outer side of the connecting rod is slidably connected to the inner wall of the limiting block.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pulling the rod, the filter slides within the thin shell, compressing the spring and causing the baffle to disengage the plug-in block from the filter screen. The L-shaped blocking block, due to gravity, slides back into the thin shell to prevent reset, allowing the filter screen to be removed for maintenance and cleaning. During installation, the new filter screen is placed in place, and the L-shaped blocking block is pulled up. The spring force causes the plug-in block to insert into the filter screen and secure it. Dust-laden gas passes through the filter screen, with dust remaining on the left side. The purified gas passes through the duct and is pressurized by the fan before being discharged from the outlet pipe. This allows for convenient filter screen replacement and maintenance, maintaining good filtration performance, reducing the amount of dust entering the fan, lowering the risk of wear on fan components, extending the fan's normal operating time, and ensuring the efficient and stable operation of the entire dust removal device.

[0024] 2. In this utility model, when the motor is started, the output end of the motor drives the turntable to rotate. The rotating shaft on the outer edge of the turntable pushes the hollow shell that is slidably connected to it to move. The hollow shell drives the rubber striking plate to move through two connecting rods. As the turntable continues to rotate, the rubber striking plate periodically hits the outside of the dust outlet, which effectively solves the problem of dust accumulating near the dust outlet due to adhesion, caking and other reasons, thus hindering normal dust discharge.

[0039] Working principle: When dust is generated during the addition of wear-resistant filler for automotive coatings, the dust-laden gas is introduced into the dust collector 2 through the dust inlet pipe 3, which is fixedly connected to the left side of the dust collector 2. At this time, the fan 14, which is fixed to the top of the support frame 1 by the base 27, is started. The fan 14 generates suction, which guides the dust-laden gas from the dust collector 2 to the right and into the protective box 4, where it is filtered through the filter screen 5.

[0040] When filter screen 5 needs to be removed, pull rod 11. Pull rod 11 slides inside thin shell 6, compressing spring 10 and causing baffle 9 to move away from protective box 4 until plug block 12 is completely disengaged from filter screen 5. At the same time, under the action of gravity, L-shaped blocking block 8 slides from L-shaped block 7 into thin shell 6, preventing baffle 9 and plug block 12 from moving under the action of spring 10, so that plug block 12 can be reinserted into filter screen 5. At this time, filter screen 5 can be removed for maintenance or cleaning. When installing, after placing the new filter screen 5 in place, first pull upwards. The L-shaped blocking block 8, under the elastic force of the spring 10, resets the baffle 9, causing the plug-in block 12 to be inserted into the filter screen 5, thus fixing the filter screen 5. When the dust-laden gas passes through the filter screen 5, the dust is intercepted on the left side of the filter screen 5. The purified gas passes through the air guide pipe 13, is pressurized by the fan 14, and is discharged from the air outlet pipe 15. This enables convenient replacement and maintenance of the filter screen 5, maintains good filtration performance, reduces the amount of dust entering the fan 14, reduces the risk of wear on the fan 14 components, extends the normal operating time of the fan 14, and maintains the efficient and stable operation of the entire dust removal device.

[0041] When dust discharge is required, the valve 16 on the outside of the dust outlet 17 is opened, the motor 18 is started, and the output end of the motor 18 drives the turntable 19 to rotate. The rotating shaft 20 on the outer edge of the turntable 19 pushes the hollow shell 21 that is slidably connected to it to move. The hollow shell 21 drives the rubber striking plate 23 to move through two connecting rods 22. As the turntable 19 continues to rotate, the rubber striking plate 23 periodically hits the outside of the dust outlet 17, which effectively solves the problem of dust accumulating near the dust outlet 17 due to adhesion, caking and other reasons, thus hindering normal dust discharge. The dust finally falls into the dust bin 26 below for collection.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
