This design not only ensures the stability of the sealing plate during the exhaust gas treatment process and prevents exhaust gas leakage, but also provides convenience for daily maintenance and replacement of the filter element. When the filter element needs to be replaced, the operator only needs to twist the hand-tightening bolt to disengage it from the corresponding hole on the dust removal box, and then the sealing plate together with the filter frame and the filter element can be easily removed from the dust removal box.

Their main function is to cooperate with the hand-tightening bolts to achieve a stable installation of the sealing plate. When the hand-tightening bolts are tightened, their ends will naturally be inserted into the inner sides of the limiting holes. This insertion method not only enhances the connection strength between the bolts and the dust collector box, but also prevents the bolts from loosening or falling off during use. In this way, the sealing plate can be more stably fixed to the front of the dust collector box, thereby ensuring the sealing and safety during the exhaust gas treatment process. At the same time, the design of the limiting holes also takes into account the convenience of operation.

When the exhaust gas passes through the filter cartridge, the wind wheel rotates due to the action of wind pressure, thereby driving the entire rotating shaft to rotate. This design cleverly utilizes the power of the exhaust gas itself and does not require an external power supply. It is both energy-saving and environmentally friendly. The rear end of the rotating shaft penetrates the dustproof screen and is fixedly installed with a turntable. The turntable is fixedly connected to the cleaning assembly. When the rotating shaft rotates, the turntable also rotates accordingly, thereby driving the cleaning assembly to clean the dustproof screen. This linkage mechanism ensures the synchronous movement of the cleaning assembly and the wind wheel, thereby realizing real-time and efficient cleaning of the dustproof screen.

At the same time, the structure of the mounting frame is stable and can withstand the damage caused during the cleaning process. Various forces ensure long-term stable operation. On the inner side of each mounting frame, limit springs are fixedly installed at equal intervals. The setting of the limit springs not only allows the brush plate to move freely within a certain range to adapt to the uneven surface of the dust screen, but also provides sufficient elastic force to ensure that the brush plate fits tightly against the dust screen to achieve effective cleaning. The brush plate is the part of the cleaning component that directly contacts the dust screen, and its front side fits against the back of the dust screen. When the power component drives the turntable to rotate, the brush plate rotates accordingly, and uses the bristles on its surface to scrape and clean the dust screen.

[0014] As a preferred technical solution, support rods are fixedly installed at equal intervals on the back of the brush plate, and the rear ends of the support rods penetrate the mounting frame. Support rods are fixedly installed at equal intervals on the back of the brush plate. These support rods not only enhance the structural strength of the brush plate, but also ensure the stability of the brush plate during rotation.

When installing, simply reinsert the slide rod into the slide slot. This design makes the device very convenient when replacing the filter element, and the overall practicality is strong, which is easy to promote and apply, and meets the user's dual needs for efficient purification and convenient maintenance;

[0017] Second, by setting up a filtering mechanism, the device can use a vacuum pump to pump exhaust gas, and the exhaust gas enters the dust removal box through the suction hopper and the filter cylinder. The wind pressure drives the wind wheel to rotate, and then drives the mounting frame and the brush plate to rotate, automatically cleaning the dust on the dustproof screen.

When the filter element 55 is saturated with adsorption and needs to be replaced, the hand-tightened bolt 58 on the fixing plate 57 can be twisted. The end of the hand-tightened bolt 58 is disengaged from the limiting hole 59, and the slide bar 53 can be pulled out from the inner side of the slide groove 52, which is convenient for the device to quickly replace and remove the filter element 55. When installing, it is only necessary to reinsert the slide bar 53 into the interior of the slide groove 52, so that the device as a whole can be quickly disassembled and replaced with the filter element 55, making the overall replacement and disassembly of the device more convenient, and the overall practicality is strong, and it is worthy of promotion and application.

[0034] By setting the filtering mechanism 6, the device can, during use, pump the exhaust gas from the outside through the operation of the vacuum pump 7, and the exhaust gas enters the interior of the dust removal box 3 through the suction hopper 63 and the filter cartridge 61, and circulates in the interior of the filter cartridge 61 in stages, and the wind pressure can drive the wind wheel 642 to rotate, and the wind wheel 642 drives the rotating shaft 641 to drive the rotating disk 643 to rotate, and the rotating disk 643 can assist in driving the mounting frame 651 to rotate, and the rotation of the mounting frame 651 can drive the brush plate 653 to rotate, and the dustproof screen 62 can be cleaned by the rotation of the brush plate 653, and the cleaned dust falls back into the interior of the collecting bucket 66. When cleaning is required, it only needs to twist open the sealing screw cover 67 for disassembly and assembly. It can be seen that during use, the device uses the wind wheel 642 to replace the motor in the prior art for driving. During cleaning, it only needs to rely on the wind pressure generated by the vacuum pump 7 for automatic cleaning. No external power supply is required for cleaning and dust prevention, and the use cost can be significantly reduced, thereby improving the overall dustproof performance of the device and facilitating the use of the device.
