[0029] The filter cartridge 1 is symmetrically provided with a slide groove 301, and the filter cartridge 1 is slidably connected with a partition 302 through the slide groove 301. A top cover 303 is clamped at the top of the partition 302 corresponding to the top position of the filter cartridge 1. A sleeve 304 is rotatably connected to the outside of the top cover 303. A packing cylinder 305 is clamped at both ends of the partition 302 corresponding to the internal position of the filter cartridge 1. A grid plate 306 is clamped at the top of the packing cylinder 305. A protrusion 307 is symmetrically clamped at one side of the top of the grid plate 306. The inside of the protrusion 307 The plug rod 308 is movably connected, and a pull plate 309 is clamped at one end of the plug rod 308, and a tension spring 310 is clamped at the outer position of the plug rod 308 between the pull plate 309 and the protrusion 307. Positioning holes 311 are opened at both ends of the partition plate 302 corresponding to the outer position of the plug rod 308. In order to facilitate disassembly and replacement, a filter screen is clamped at the bottom of the inner wall of the stuffing cylinder 305, and one end of the plug rod 308 is embedded in the positioning hole 311. The inner wall of the sleeve 304 is connected to the outer side of the filter cylinder 1 through a threaded connection;

[0030] A flow regulating mechanism 4 is provided at the bottom of the filter cartridge 1, and the flow regulating mechanism 4 includes a rotating drum 401, a lifting rod 402, a sealing plate 403, a clamping block 404, a driven gear 405, an adjusting rod 406 and a driving gear 407;

[0031] The bottom end of the filter cartridge 1 is rotatably connected to a rotating drum 401, and the inner wall of the rotating drum 401 is connected to a lifting rod 402 through a thread, and a sealing plate 403 is clamped on the top of the lifting rod 402, and a clamping block 404 is clamped on the outer side of the sealing plate 403 at a position corresponding to the inner side of the slide groove 301, and a driven gear 405 is fixedly sleeved on the outer side of the rotating drum 401, and an adjusting rod 406 is rotatably connected to the inner wall of the filter cartridge 1 corresponding to the top position of the driven gear 405, and a driving gear 407 is clamped on one end of the adjusting rod 406. In order to facilitate the adjustment of the time the gas stays in the filter cartridge 1, the outer side of the sealing plate 403 fits the inner wall of the filter cartridge 1, and the driven gear 405 and the driving gear 407 are both bevel gears, and the driven gear 405 and the driving gear 407 are meshed with each other;
