Referring to fig. 5 and 6, when the dust-containing gas is discharged into the dust removing chamber 13, the dust-containing gas may have a certain impact on the surface of the filter cartridge 51 located at the upper portion, and the filtering load of the surface of the filter cartridge 51 located at the upper portion is also greater than that of the surface of the filter cartridge 51 located at the lower portion, so that the filter cartridge 51 may be easily damaged locally. When high-pressure air is introduced into the inner cavity of the filter cartridge 51 to clean the filter cartridge 51, the second control valve 46 opens the driving branch pipe 44, the driving branch pipe 44 fills part of the high-pressure air into the airflow cavity 533, the second baffle 535 rotates towards the direction close to the first baffle 534 under the action of the air pressure, and the return spring 536 is compressed; second baffle 535 drives rotatory drain pan 532 and rotates, and rotatory drain pan 532 drives through first elasticity centre gripping subassembly 2 and strains a 51 rotation, not only can play certain deashing effect to straining the dust on the cartridge 51 to make and strain a 51 and can take place to rotate and trade the face, make and strain a 51 and be located the bottom originally global rotate to upper portion, with full play strain a 51 whole filtering quality of section, improve and strain a 51 life, and can play certain vibration cleaning effect to straining the dust on 51 surface.
Referring to fig. 5, in order to ensure the stability when the base 53 drives the filter cartridge 51 to rotate, the outer wall of the support rod 541 is provided with a limit groove 542 along the length direction thereof, the inner wall of the filter cartridge 51 is fixed with a limit block 511 adapted to each limit groove 542, and the limit block 511 is located in the limit groove 542.

The implementation principle of the down-flow type filter cartridge dust remover in the embodiment of the application is as follows: when the dust-containing gas enters the housing 1 through the gas inlet 15, dust in the gas is deposited on the surface of the filter cartridge 51, and the purified gas penetrates the filter cartridge 51 to enter the inner cavity of the filter cartridge 51, then flows into the breather chamber 14 and is discharged from the gas outlet 16. When the surface dust on the filter cartridge 51 is more, high-pressure air is introduced into the inner cavity of the filter cartridge 51 through the ash removal blowback mechanism 4, and the high-pressure air passes through the filter cartridge 51 from inside to outside to remove the dust attached to the outer surface of the filter element. Meanwhile, under the impact of the high-pressure gas, the first spring 21 and the second spring 31 of the filter cartridge 51 are elastically deformed, so that the filter cartridge 51 can reciprocate along the length direction of the support rod group 54, and then the dust on the inner surface and the outer surface of the filter cartridge 51 can be shaken off, thereby realizing the effective combination of the high-pressure gas back-blowing dust removal and the mechanical vibration dust removal, and improving the dust removal effect on the filter cartridge 51.
The scraping plates 55 on the support rod group 54 slide in the direction away from the partition 17 under the pressure of the high-pressure gas to scrape and clean the dust on the inner wall of the filter cartridge 51, and when the high-pressure gas is discharged out of the filter cartridge 51 in a back blowing manner, the high-pressure gas slides to the initial position under the action of the self-weight of the high-pressure gas. After the filter cartridge 51 has been in operation for a period of time, the operator can activate the second control valve 46 to drive the branch pipe 44 to fill a part of the high-pressure air into the airflow chamber 533, and the second baffle 535 is rotated by the air pressure in a direction approaching the first baffle 534 and compresses the return spring 536; the second baffle 535 drives the rotary bottom case 532 to rotate, and the rotary bottom case 532 drives the filter cartridge 51 to rotate through the first elastic clamping component 2, so that the filter cartridge 51 originally located at the bottom of the peripheral surface rotates to the upper part, the overall filtering performance of the filter cartridge 51 is fully exerted, and the service life of the filter cartridge 51 is prolonged.
