When air enters the air inlet 2, the wind pressure pushes the second filter 301 to move backward. After the air enters, the elastic telescopic rod 1 302 pushes the second filter 301 to reset. During the reset process, the first protrusion 306 and the second protrusion 307 move and knock to generate vibration, which shakes off the dust on the second filter 301. The interior of the box 1 is fixedly connected to the hydraulic tank 1 303. The piston at one end of the hydraulic tank 1 303 is slidably connected to the hydraulic rod 1 304. The other end of the hydraulic rod 1 304 is fixedly connected to the second filter 301. The second filter 301 is slidably connected to the top of the storage box 6. One side of the filter screen 2 301 is fixedly connected with a dust cover 601. After the air intake is completed, the dust cover 601 is pushed open by the filter screen 2 301, and the dust that is shaken off enters the storage box 6 through the dust cover 601. The piston at one end of the hydraulic tank 1 303 close to the inner side of the filter screen 1 201 is slidably connected to the hydraulic rod 2 310. The end of the hydraulic rod 2 310 passes through and is rotatably connected to the rotating rod 1 311. The outer side of the rotating rod 1 311 is rotatably connected to the cylinder brush 308. The cylinder brush 308 contacts the inner surface of the filter screen 1 201. The cylinder brush 308 rotates to brush the dust on the filter screen 1 201 down into the storage box 6.

At the same time, during the filtration process, it is ensured that the dust inside the storage box 6 will not be blown up again and attached to the filter net, thereby solving the problem of complicated and tedious cleaning operations, and thus achieving the effect of unobstructed filter net and convenient dust removal and recovery.

[0027] When the above-mentioned equipment is used in practice, during the production process of hydroxypropyl methylcellulose, when the air inlet 2 starts to take in air, the hydroxypropyl methylcellulose dust in the air enters the air inlet 2 and is filtered for the first time through the filter 1 201. The wind pressure presses the filter 2 301 to slide backward, and the filter 2 301 slides backward to pull the dust cover 601 to close the storage box 6. The filter 2 301 pushes the hydraulic rod 1 304 to enter the hydraulic tank 1 303. The hydraulic rod 2 310 extends from the inner end of the hydraulic tank 1 303 close to the filter 1 201. The hydraulic rod 2 310 moves downward, driving the gear 312 to rotate on the rack 309. The rotation of the gear 312 drives the rotating rod 1 311 to rotate and move downward at the same time. The rotation of the rotating rod 1 311 drives the barrel brush 308 to rotate. The barrel brush 308 rotates and moves downward at the same time to clean the filter 1 201 for the first time. When the air intake ends and the wind pressure disappears, the elastic telescopic rod 1 302 pushes the filter 2 301 to reset. At the same time, the filter 2 301 pushes the dust cover 601 to open the storage box 6. During the reset process, the protrusion 1 306 and the protrusion 2 307 move and knock to generate vibration, which shakes off the dust on the filter 2 301, and the fallen dust enters the storage box 6. The filter 2 301 pulls the hydraulic rod 1 304 to extend the hydraulic tank 1 303. The hydraulic tank 1 303 is close to the inner end of the filter 1 201 and retracts the hydraulic rod 2 310. The hydraulic rod 2 310 moves upward, driving the gear 312 to rotate in the opposite direction on the rack 309. The rotation of the gear 312 drives the rotating rod 1 311 to rotate and move upward at the same time. The rotation of the rotating rod 1 311 drives the cylindrical brush 308 to rotate. The cylindrical brush 308 rotates and moves upward at the same time to clean the filter 1 201 for the second time.

The pawl 412 is hinged on the inner side of the rotating ring 402, and the movable side of the pawl 412 is fixedly connected to the inner side of the rotating ring 402 by the elastic telescopic rod 2 413. When the ratchet 404 rotates forward, the pawl 412 cannot buckle the ratchet 404. When the ratchet 404 rotates reversely, the pawl 412 clamps the ratchet 404 to make the rotating ring 402 start to rotate. The top of the bracket 401 is fixedly connected to the hydraulic tank 2 406. The piston on the inner side of the hydraulic tank 2 406 near the cylinder brush 308 is slidably connected to the hydraulic rod 3 407.

The bottom end of the support plate 410 is rotatably connected to the roller 411. The roller 411 contacts the outer side of the ring body of the rotating ring 402. The outer side of the ring body of the rotating ring 402 is provided with an arc-shaped notch. When the bracket 401 is located at the top of the cylinder brush 308, the roller 411 is located at the arc-shaped notch. When the rotating ring 402 starts to rotate When the cylinder 401 is in motion, the roller 411 starts to roll from the arc-shaped notch along the contour of the rotating ring 402, pushing the hydraulic rod 408 to retract the hydraulic tank 2 406. By setting the cylinder brush cleaning device 4 and cooperating with the dust removal device 3, the cylinder brush 308 can be cleaned after each cleaning of the filter screen 201, ensuring that the dust of hydroxypropyl methylcellulose will not adhere to the cylinder brush 308 and solidify and clump, resulting in a decrease in the cleaning ability of the cylinder brush 308, thereby solving the problem of the cleaning ability of the cylinder brush 308 being destroyed by the dust of hydroxypropyl methylcellulose, thereby solving the problem of the cleaning ability of the cylinder brush 308 being destroyed by the dust of hydroxypropyl methylcellulose, thereby solving the effect of ensuring the cleaning ability of the cylinder brush 308.

[0029] When the above-mentioned equipment is used in a specific manner, during the production process of hydroxypropyl methylcellulose, when the air inlet 2 starts to flow in, the hydroxypropyl methylcellulose dust in the air enters the air inlet 2 and is filtered for the first time through the filter screen 1 201. The wind pressure presses the filter screen 2 301 to slide backward, and the filter screen 2 301 slides backward to pull the dust cover 601 to close the storage box 6. The filter screen 2 301 pushes the hydraulic rod 1 304 to enter the hydraulic bin 1 303. The hydraulic bin 1 303 extends the hydraulic rod 2 310 at one end near the inner side of the filter screen 1 201. The hydraulic rod 2 310 moves downward, driving the gear 312 to rotate on the rack 309. The rotation of the gear 312 drives the rotating rod 1 311 to rotate and move downward at the same time. The rotation of the rotating rod 1 311 drives the cylinder brush 308 to rotate, and the cylinder brush 30 8 rotates and moves downward at the same time to clean the filter 201 for the first time.

The rotating rod 2 403 rotates in the limiting ring 415. The rotation of the rotating rod 2 403 drives the ratchet 404 to rotate forward. The ratchet 404 pushes the pawl 412, and the elastic telescopic rod 2 413 pushes the pawl 412 to reset. When the air intake ends and the wind pressure disappears, the elastic telescopic rod 1 302 pushes the filter 2 301 to reset. At the same time, the filter 2 301 pushes the dust cover 601 to open the storage box 6. During the reset process, the protrusion 1 306 and the protrusion 2 307 move and knock to generate vibration, which shakes off the dust on the filter 2 301, and the fallen dust enters In the storage box 6, the filter screen 2 301 pulls the hydraulic rod 1 304 to extend out of the hydraulic bin 1 303. The hydraulic bin 1 303 retracts the hydraulic rod 2 310 near the inner end of the filter screen 1 201. The hydraulic rod 2 310 moves upward, driving the gear 312 to rotate in the opposite direction on the rack 309. The rotation of the gear 312 drives the rotating rod 1 311 to rotate and move upward at the same time. The rotating rod 1 311 rotates and drives the barrel brush 308 to rotate. The barrel brush 308 rotates and moves upward at the same time to clean the filter screen 1 201 for the second time. At the same time, the hydraulic rod 2 310 drives the bracket 401 to move upward, and the rotating rod 1 311 drives the rotating rod 2 403 to rotate through the transmission belt 405.

By setting up the stirring device 5 and cooperating with the dust removal device 3, the dust removal device 3 drives the stirring device 5 to stir the water tank 502 during operation, and guides the dust into the water body through the air flow. At the same time, stirring avoids the deposition of dust in the water tank 502, thereby solving the problem of dust deposition in the water tank 502, and then achieving the effect of ensuring smooth water flow in the water tank 502 and cleaning the interior of the box body 1.

[0031] When the above-mentioned equipment is used in a specific manner, during the production process of hydroxypropyl methylcellulose, when the air inlet 2 starts to flow in, the hydroxypropyl methylcellulose dust in the air enters the air inlet 2 and is filtered for the first time through the filter screen 1 201. The wind pressure presses the filter screen 2 301 to slide backward, and the filter screen 2 301 slides backward to pull the dust cover 601 to close the storage box 6. The filter screen 2 301 pushes the hydraulic rod 1 304 to enter the hydraulic bin 1 303. The hydraulic bin 1 303 is close to the end of the support platform 505 to push out the hydraulic rod 5 506. The hydraulic rod 506 pushes the stirring rod 504 to make a circular motion in the water tank 502, and the water tank The foreign matter deposited in 502 is removed, and the air enters the second layer of the box body 1 through the air inlet 1 313, and enters the third layer of the box body 1 from the air inlet 2 507 through the filter cartridge 501. When the air intake ends and the wind pressure disappears, the elastic telescopic rod 1 302 pushes the filter screen 2 301 to reset, and the filter screen 2 301 pulls the hydraulic rod 1 304 out of the hydraulic bin 1 303. At the same time, the hydraulic rod 506 is retracted into the hydraulic bin 1 303. The hydraulic rod 506 drives the stirring rod 504 to reset, and at the same time, the stirring generates airflow to assist in guiding the dust into the water tank 502. The mixed fluid in the water tank 502 flows out of the box body 1 through the water outlet 503.
