[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. A self-cleaning assembly is provided. Under the limiting guidance of the guide rod, the dust exhaust pipe is driven to rise by the lifting motor, and the dust collecting hopper is driven to rotate by the servo motor, so that the fixed head is embedded in the corresponding fixed hole ear, and the filter cartridge core is magnetically fixed by the fixed magnetic ring. The dust exhaust pipe and the filter cartridge core are driven to descend by the servo motor and the lifting motor, and the electric magnetic ring is energized to connect the discharge pipe with the corresponding input pipe and the dust exhaust pipe. At this time, the high-pressure gas flows through the gas main pipe, the branch gas box, the inner nozzle and the inner nozzle hole in sequence. The high-pressure gas impacts the inner wall of the filter cartridge core to blow away the dust. At the same time, the high-pressure gas quickly flows through the inside of the dust exhaust pipe, and the fallen dust passes through the dust collecting hopper into the inside of the dust exhaust pipe and is discharged from the discharge pipe with the air flow to collect the dust and protect the working environment on site. At the same time, the servo motor drives the filter cartridge core to rotate continuously, so that the gas sprayed from the inner nozzle hole can fully act on the inner wall of the filter cartridge core, increase the action area of ​​the gas sprayed from the inner nozzle hole, and achieve better cleaning effect.

[0024] When the filter cartridge needs to be washed, the water main pipe is connected to the branch air box by controlling the electric control valve. Clean water flows through the water main pipe and the branch air box in turn into the inner nozzle and finally sprays out from the inner spray hole. The servo motor drives the filter cartridge to rotate continuously. The water sprayed from the inner spray hole acts more fully on the filter cartridge. There is no need to remove the filter cartridge manually for cleaning. The operation is convenient and the labor cost is reduced.

[0025] By controlling the dust exhaust pipe to be connected with a row of filter cartridges, when the connected filter cartridges are cleaned, other filter cartridges can continue to filter the air. When one row of filter cartridges is cleaned, the lifting motor cooperates with the electric slide rail to drive the dust exhaust pipe to move and clean the remaining rows one by one. There is no need to shut down the entire device to clean the filter cartridges, and the working continuity is good.

[0026] When the filter cartridge needs to be replaced, the fixed head is docked with the fixed hole ear by controlling the lifting motor, electric slide rail and servo motor, and the filter cartridges in each row are removed one by one. After removal, the filter cartridges are manually removed from the top of the support ring and replaced with new ones. The lifting motor, electric slide rail and servo motor are then controlled to replace the new filter cartridges back to their original positions. The filter cartridges are easy to disassemble and assemble.

[0027] 2. An enhanced drying component is provided. Under the connection and driving action of the driving wheel, the driven wheel and the driving toothed belt, the rotating motor can drive the inner nozzle and the filter cartridge core to rotate, and cooperate with the rotation of the filter cartridge core to make the gas ejected from the inner nozzle hole act on the inner wall of the filter cartridge core faster and better, so that the cleaning effect is better and the speed is faster. At the same time, the high-pressure air pressure flows through the heating tank, the external spray main pipe, the conveying branch pipe, the connecting branch pipe, the connecting ring box, and the connecting hole in turn to enter the ventilation ring box, and finally flows into the outer nozzle and is ejected from the outer nozzle. The ejected gas impacts the outside of the filter cartridge core. Under the impact of the airflow, most of the dust remaining in the filter cartridge core enters the filter cartridge core and finally falls into the dust exhaust pipe, thereby improving the cleaning quality. At the same time, under the connection and driving action of the linkage rod, the swinging electric push rod drives the swinging rod to move back and forth, thereby driving the ventilation ring box and the outer nozzle to rotate back and forth, so that the gas ejected from the outer nozzle hole fully acts on the outside of the filter cartridge core, increasing the effective area of ​​the outer nozzle hole, and further improving the cleaning quality.

[0028] When the filter cartridge is washed with water, the servo motor can also drive the filter cartridge to rotate faster, and most of the water will be thrown out under the action of centrifugal force. The thrown water falls on the top of the isolation plate, and under the guidance of the water inlet, the water on the top of the isolation plate flows through the water inlet and the water inlet into the water receiving box. After centrifugal dehydration is completed, the electric control valve is controlled to connect the gas main pipe with the branch gas box, and the inner heating wire and the outer heating wire are in operation. The heated air pressure is sprayed out from the inner spray hole and the outer spray hole, and the rotating motor drives the inner nozzle to rotate, and the swinging electric push rod drives the outer nozzle to swing. The hot air acts on the inside and outside of the filter cartridge at the same time, and the filter cartridge is quickly dried. There is no need for manual disassembly and cleaning before drying. The work continuity is higher and the cleaning speed is faster.

[0029] To sum up, in the self-cleaning assembly, the high-pressure gas enters the inner nozzle through the gas main pipe and the branch gas box in turn, and is sprayed out from the inner spray hole to blow off the dust adsorbed on the inner wall of the filter tube core, thereby strengthening the drying component. The rotating motor can drive the inner nozzle to rotate, so that the inner nozzle has a cleaning function as well as a drying function. The equipment is more integrated, and there is no need to use a separate drying equipment for drying, thereby reducing the equipment's footprint. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] The working principle and use process of the present invention are as follows: when filtering the air, the exhaust fan 328 is started. Under the guidance of the exhaust fan 328, the external air first enters the inside of the protective mesh plate 201 through the outside of the protective mesh plate 201 on the four sides of the top of the device base 1. The protective mesh plate 201 performs preliminary filtration on the external air to filter out larger impurities floating in the air, and then flows through the bottom of the filter cartridge 226 to enter the inside of the filter cartridge 226, and then passes through the side wall of the filter cartridge 226 and the side wall of the exhaust hole 236 in turn to enter the space between the top of the stable partition 233 and the sealing box 203, and finally flows through the filter cartridge box 326 and is discharged from the exhaust end of the exhaust fan 328. The air is filtered three times, and the filtering effect is good.

[0062] When the filter cartridge 226 needs to be cleaned, the lifting motor 209 drives the lifting screw 208 to rotate. Under the limiting guidance of the guide rod 206, the lifting motor 209 drives the dust exhaust pipe 210 to rise, the driving gear 223 meshes with the driven gear ring 221, and the servo motor 222 drives the dust collecting hopper 217 to rotate. In coordination with the rise of the dust exhaust pipe 210, the fixed head 220 is embedded in the corresponding fixed hole ear 228. At this time, the top surface of the support ring 218 fits with the bottom surface of the sealing iron pipe 227, and the fixed magnetic ring 219 magnetically fixes the sealing iron pipe 227. Under the action of the magnetic force, the filter cartridge 226 can be more stably fixed on the top of the support ring 218. The servo motor 222 drives the filter cartridge 226 to rotate. The male support ear 229 is moved out from the female support ear 225, and then the lifting motor 209 drives the dust exhaust pipe 210 to descend, and the filter cartridge 226 follows and descends stably. When the docking magnetic rings 212 at both ends of the dust exhaust pipe 210 move to the position of the adjacent electric magnetic ring 215, the lifting motor 209 stops running, and the electric magnetic ring 215 is energized to connect the discharge pipe 214 with the corresponding input pipe 213 and the dust exhaust pipe 210. At the same time, the stabilizing electric push rod 234 drives the stabilizing partition plate 233 to descend, so that the rotating ball 235 is embedded in the ball groove 231. The ball groove 231 limits the rotating ball 235. When the servo motor 222 drives the filter cartridge 226 to rotate, the filter cartridge 226 can rotate stably.

[0063] At this time, the external air pump connected to the gas main pipe 243 is started, and the high-pressure gas enters the inner nozzle 238 through the gas main pipe 243 and the branch gas box 237 in turn, and is finally ejected from the inner nozzle hole 239. The ejected high-pressure gas impacts the inner wall of the filter cartridge 226, and blows off the dust adsorbed on the inner wall of the filter cartridge 226. At the same time, the external air pump connected to the input pipe 213 is started, and the high-pressure gas flows through the input pipe 213 and the dust exhaust pipe 210 in turn, and is finally discharged from the other end of the exhaust pipe 214. The high-pressure gas quickly flows through the dust exhaust pipe 210. According to the Bernoulli principle, the pressure inside the dust exhaust pipe 210 is lower than the pressure inside the connected filter cartridge 226. The fallen dust passes through the dust receiving hopper 217 and enters the dust exhaust pipe 210, and is finally discharged from the exhaust pipe 214 with the airflow. The exhaust pipe 214 is connected to an external collection device to collect the dust.

[0064] At the same time, the servo motor 222 drives the filter cartridge 226 to rotate continuously, so that the gas ejected from the inner spray hole 239 can fully act on the inner wall of the filter cartridge 226, increasing the effective area of ​​the gas ejected from the inner spray hole 239 and achieving a better cleaning effect. At the same time, the rotating motor 318 is started, and under the connected driving action of the driving wheel 319, the driven wheel 320 and the driving toothed belt 321, the rotating motor 318 drives the inner nozzle 238 to rotate in the opposite direction of the filter cartridge 226. The rotation of the inner nozzle 238 cooperates with the rotation of the filter cartridge 226, so that the gas ejected from the inner spray hole 239 can act on the inner wall of the filter cartridge 226 faster and better, achieving a better cleaning effect and a faster speed. At the same time, the external air pump connected to the heating tank 310 is started, and the high-pressure air pressure flows through the heating tank 310, the external spray main pipe 309, the conveying branch pipe 308 and the connecting branch pipe in turn. The tube 307 enters the interior of the connecting ring box 306, then flows through the connecting hole 305 into the interior of the ventilation ring box 302, and finally flows into the interior of the outer nozzle 303 and is ejected from the outer nozzle hole 304. The ejected gas impacts the outer side of the filter cartridge 226. Under the impact of the airflow, most of the dust remaining in the filter cartridge 226 enters the interior of the filter cartridge 226 and finally falls into the dust exhaust pipe 210, thereby improving the cleaning quality. At the same time, under the connection and driving action of the linkage rod 314, the swinging electric push rod 315 drives the swinging rod 312 to move back and forth, and the swinging teeth 313 mesh with the outer nozzle gear ring 301. The swinging electric push rod 315 drives the ventilation ring box 302 and the outer nozzle 303 to rotate back and forth, so that the gas ejected from the outer nozzle hole 304 fully acts on the outer side of the filter cartridge 226, thereby increasing the effective area of ​​the outer nozzle hole 304 and further improving the cleaning quality.

[0065] When the dust inside the filter cartridge 226 is dirty and the impact airflow cleaning effect is poor, the filter cartridge 226 needs to be washed with water, and the electric control valve 241 is controlled to connect the water main pipe 242 with the branch air box 237, and the external water pump is started. Clean water flows through the water main pipe 242 and the branch air box 237 in turn into the inner nozzle 238, and finally sprays out from the inner spray hole 239. The sprayed water acts on the filter cartridge 226. At the same time, the servo motor 222 drives the filter cartridge 226 to rotate continuously, and the rotating motor 318 drives the inner nozzle 238 and the filter cartridge 226 rotates in the opposite direction, and the water sprayed from the inner spray hole 239 acts more fully on the filter cartridge 226. A part of the sewage produced by cleaning flows through the dust collecting hopper 217 into the dust exhaust pipe 210 and is discharged from the discharge pipe 214. The other part of the water falls on the top of the isolation plate 202. Under the guidance of the water guide groove 322, the water on the top of the isolation plate 202 flows through the water guide groove 322 and the water receiving port 323 into the water receiving box 324 and is finally discharged from the drain pipe 325. There is no need to manually remove the filter cartridge 226 for cleaning, thereby reducing labor costs.

[0066] The dust exhaust pipe 210 is connected to a row of filter cartridges 226. When the connected filter cartridges 226 are cleaned, the other filter cartridges 226 can continue to filter the air. When the cleaning of one row of filter cartridges 226 is completed, the lifting motor 209 cooperates with the electric slide rail 204 to drive the dust exhaust pipe 210 to move and clean the remaining rows one by one. There is no need to shut down the entire device to clean the filter cartridges 226, and the working continuity is good.

[0067] When the filter cartridge 226 is washed with water, the servo motor 222 drives the filter cartridge 226 to rotate faster. Under the action of centrifugal force, most of the water inside the filter cartridge 226 is thrown out, and the thrown out water falls on the top of the isolation plate 202. Under the guidance of the water guide groove 322, the water on the top of the isolation plate 202 flows through the water guide groove 322 and the water receiving port 323 into the water receiving box 324, and is finally discharged from the drain pipe 325. After the centrifugal dehydration is completed, the electric control valve 241 is controlled to connect the gas main pipe 243 with the branch gas pipe 244. The box 237 is connected, the inner heating wire 317 and the outer heating wire 311 are in operation, the external air pump is started, and the heated air pressure is ejected from the inner spray hole 239 and the outer spray hole 304, and the inner spray pipe 238 is driven to rotate by the rotating motor 318, and the outer spray pipe 303 is driven to swing by the swinging electric push rod 315, and the hot air acts on the inner and outer sides of the filter cartridge 226 at the same time, and the filter cartridge 226 is quickly dried. After manual disassembly and cleaning, it is no longer necessary to use a drying device alone for drying, which has higher working continuity and faster cleaning speed;

[0068] When the filter cartridge 226 needs to be replaced, the fixed head 220 is docked with the fixed hole ear 228 by controlling the lifting motor 209, the electric slide rail 204 and the servo motor 222, and the filter cartridge 226 of each row is removed one by one. After removal, the filter cartridge 226 is manually removed from the top of the support ring 218 and replaced with a new filter cartridge 226. The lifting motor 209, the electric slide rail 204 and the servo motor 222 are then controlled to replace the new filter cartridge 226 back to its original position. The filter cartridge 226 is easy to disassemble and assemble.
