[0032] Working principle explanation:

[0033] The pre-filtered exhaust air from the hot chamber enters the filter box 1 through the inlet pipe 4 and is filtered by the filter element 10. The air then exits through the outlet pipe 5, producing gas that meets the specified standards. It is worth noting that when the filter element 10 needs to be replaced, the first mechanical lock 21 is opened and the first box door 20 is opened. The new filter element 10 and its mounting bracket 11 are pushed into the mounting box 2. After closing the first box door 20, the first electric telescopic rod 6 is activated. The first electric telescopic rod 6 drives the first top block 7 to move, pushing the new mounting bracket 11 and filter box 10 upwards. The new mounting bracket 11 and filter box 10 push the mounting bracket 11 and filter box 10 that need to be replaced upwards. The first limiting block 14 is forced to retract into the first sliding groove 12 and compresses the first spring 13. The second limiting block 18 is forced to retract into the first... The second slide groove 16 compresses the second spring 17, and the mounting bracket 11 and filter box 10 that need to be replaced are replaced by the new mounting bracket 11 and filter box 10. At this time, the first limiting block 14 and the second limiting block 18 match the first limiting groove 15 and the second limiting groove 19 on the new mounting bracket 11, respectively. Under the action of gravity, the first limiting block 14 and the second limiting block 18, the new mounting bracket 11 and filter box 10 are installed. The second mechanical lock 23 is opened and the second box door 22 is opened. The second electric telescopic rod 8 is activated to make the second top block 9 move and push out the mounting bracket 11 and filter box 10 that need to be replaced placed on the new mounting bracket 11 and filter box 10. This disassembly and assembly method is completely unattended, ensuring the safety of the operator.

[0034] Preferably, the first door 20 is equipped with a sealing strip. This structural design makes the first door 20 have a better sealing effect.

[0035] Preferably, the second door 22 is equipped with a sealing strip. This structural design makes the second door 22 have a better sealing effect.

[0036] Preferably, the first limiting block 14 is equipped with a rubber pad. This structural design reduces frictional damage to the first limiting block 14 and extends the service life of the equipment.

[0037] Preferably, the second limiting block 18 is equipped with a rubber pad. This structural design reduces frictional damage to the second limiting block 18 and extends the service life of the equipment.
