[0031] A large amount of dust is generated during the operation of the belt sander. The friction between the sanding belt and the processed material is the main reason for the generation of dust. The particles on the surface are ground down to form dust. Its composition depends on the nature of the processed material. Dust has a wide range of particle size distribution, ranging from larger particles to tiny inhalable particles. Tiny particles are more likely to be suspended in the air and inhaled by the human body. In order to protect human health and prevent the problem of air pollution caused by suspended dust, a dust removal device is needed to collect and process the dust to solve the problem of dust diffusion and human inhalation. Existing dust removal equipment usually uses a filter element to filter the dust in the air. Since dust easily adheres to the filter element, long-term use will cause the filter element to be blocked, thereby affecting the filtering effect; therefore, a dust removal device that can clean the dust on the filter element is needed.

[0033] In the examples of this application, refer to Figures 1 to 6 The above-mentioned cartridge dust collector includes: a rectangular box body 1, the lower end of the box body 1 is supported on the ground by two rectangular plate-shaped support members 2, the support member 2 is fixedly connected to the box body 1, and a first partition 110 and a second partition 120 are horizontally arranged in the box body 1, the first partition 110 and the second partition 120 are both sealed and fixedly connected to the inner wall of the box body 1, and the first partition 110 and the second partition 120 divide the box body 1 into three spaces, which are an exhaust space 3, a blowing space 4, and a filtering space 5 from top to bottom, wherein the exhaust space 3 is used to discharge filtered air, the blowing space 4 is used to accommodate the blowing assembly, and the filtering space 5 is used to filter dust in the air.

[0034] refer to Figure 1 and Figure 2An air inlet 130 is provided on the side of the box body 1 corresponding to the filter space 5, and the air inlet 130 is connected to an air inlet pipe, and the other end of the air inlet pipe is connected to a dust collecting structure for collecting dust and transporting it to the filter space 5 through the air inlet pipe. An air outlet 140 is provided on the side of the box body 1 corresponding to the exhaust space 3 for discharging the filtered and dust-removed air into the outside air. The air outlet 140 can also be connected to an air outlet pipe, and the other end of the air outlet pipe is connected to a designated position for discharging air to the designated position.

[0035] refer to Figure 2 and Figure 4 A plurality of filter cartridges 510 are arranged in the filter space 5, and the filter cartridges 510 can filter dust and irritating odors in the air. The plurality of filter cartridges 510 are evenly distributed in a matrix, and the axis of the filter cartridge 510 is arranged perpendicularly to the second partition plate 120. The filter cartridge 510 is arranged as a cylindrical structure with one end open, and the open end of the filter cartridge 510 is rotatably mounted on the second partition plate 120 through a bearing, and a first through hole is provided on the second partition plate 120 corresponding to the filter cartridge 510, so that the blowing space 4 is communicated with the filter cartridge 510, so that the air filtered by the filter cartridge can enter the blowing space.

[0036] refer to Figure 2 A guide plate 520 is arranged in the filter space 5 between the air inlet 130 and the filter cartridge 510. The guide plate 520 is arranged vertically with the second partition plate 120. Three side surfaces of the guide plate 520 are fixedly connected to the second partition plate 120 and the inner wall of the box body 1 respectively. There is a certain distance between the lower side surface of the guide plate 520 and the box body 1 for air to pass through, so that the air passing through the air inlet can enter the filter space through the distance on the lower side of the guide plate. The design of the guide plate can prevent the air from directly impacting the filter cartridge.

[0037] refer to Figure 2 and Figure 4 A blowing assembly is provided in the blowing space 4, and the blowing assembly is used to clean the dust adhering to the filter cartridge 510. An ash hopper 530 is provided at the lower end of the filter space 5 for collecting dust. The ash hopper 530 is sealed and fixedly connected to the inner wall of the box body 1. An ash bucket 540 is provided at the lower end of the ash hopper 530. The ash bucket 540 is detachably connected to the ash hopper 530 through a snap-on structure. The ash bucket 540 is communicated with the filter space 5 through the ash hopper 530. When the blowing assembly cleans the filter cartridge 510, the dust on the filter cartridge 510 will fall into the ash bucket 540 through the ash hopper 530.

[0038] refer to Figure 1 and Figure 2A plurality of universal wheels 541 are installed on the bottom surface of the ash bucket 540 to facilitate the movement of the ash bucket. A hand-held portion 542 is installed on the side of the ash bucket 540. When the dust in the ash bucket 540 is full, the ash bucket 540 can be separated from the ash hopper 530 by opening the snap structure, and then the ash bucket 540 can be pulled by the hand-held portion to move, which facilitates the transportation of dust.

[0039] refer to Figure 2 and Figure 4 A fan 310 and a motor 320 are provided in the exhaust space 3. The fan 310 is fixedly mounted on the first partition plate 110. A second through hole is provided on the first partition plate 110 corresponding to the air inlet of the fan 310, so that the fan 310 is communicated with the blowing space 4. The air outlet of the fan 310 is communicated with the exhaust space 3, so that the fan 310 can suck the air in the blowing space 4 and discharge it into the exhaust space 3. The motor 320 is fixedly mounted on the outer casing of the fan 310, and the output shaft of the motor 320 is connected to the input shaft of the fan, so that the motor 320 can drive the fan 310 to operate.

[0040] refer to Figure 3 and Figure 4 The blowing assembly includes a pulse solenoid valve 401. The pulse solenoid valves 401 are arranged at the openings of the filter cartridge 510 in the blowing space 4. An air bag 402 is arranged between the pulse solenoid valves 401 in the blowing space 4. The air bag 402 is used to store compressed air. The air bag 402 is fixedly installed on the second partition plate 120. The pulse solenoid valves 401 are connected to the air bag 402 through pipes 403. The air bag 402 is connected to the air supply equipment through an air pressure pipe. The air supply equipment is used to transport the compressed air to the air bag 402 through the air pressure pipe. When the pulse solenoid valve 401 is started, the pulse solenoid valve 401 will spray the compressed gas into the filter cartridge 510, thereby blowing the dust adhered to the surface of the filter cartridge 510 into the ash hopper 530 below.

[0041] refer to Figure 5 and Figure 6 An airflow guiding assembly is arranged in the filter cartridge 510, and the airflow guiding assembly includes a conical diverter block 511, which is coaxially arranged with the corresponding filter cartridge 510, and the end with a smaller diameter of the diverter block 511 faces the opening of the filter cartridge 510. When the pulse solenoid valve 401 blows air to the filter cartridge 510, the diverter block can disperse the gathered airflow to the surroundings, and the dispersed airflow will blow to the side wall of the filter cartridge 510, thereby blowing off the dust on the side wall of the filter cartridge.

[0042] refer to Figure 5 and Figure 6, a plurality of spiral blades 512 are arranged on the side of the diverter block 511, and the plurality of blades 512 are evenly distributed around the diverter block 511. The blades 512 and the diverter block 511 are integrally formed. Each blade 512 is fixedly connected to the inner wall of the corresponding filter cartridge 510 by a connecting block 513, that is, a plurality of circumferentially evenly distributed connecting blocks 513 fix the blades 512 and the diverter block 511 in the corresponding filter cartridge 510. When the pulse solenoid valve 401 is pressed against the filter cartridge 510, the blades 512 and the diverter block 511 are fixedly installed in the corresponding filter cartridge 510. When blowing, the rapidly blown airflow will impact the diverter block 511 and the spiral blades 512. Under the blowing of the airflow, the blades 512 will drive the corresponding filter cartridge to rotate rapidly through the connecting block 513. The rapidly rotating filter cartridge will separate the adhered dust from the filter cartridge through the centrifugal force. At the same time, since the diameter of the diverter block increases from top to bottom, combined with the setting of the spiral blades, the effect of gathering the airflow can be increased, so that the airflow has a greater impact force to rush to the side wall of the filter cartridge, further increasing the dust removal effect.

[0043] refer to Figure 5 A vertical brush 6 is arranged on the outside of the filter cartridge 510, one end of the brush 6 is fixedly mounted on the second partition plate 120, the bristles of the brush 6 are in contact with the outer side surface of the corresponding filter cartridge 510, and when the filter cartridge 510 rotates, the brush 6 can further brush off the dust on the outer surface of the filter cartridge 510.

[0044] refer to Figure 1 A plurality of inspection ports are provided on the outside of the box body 1, and cover plates 7 are arranged outside the inspection ports. The cover plates 7 are sealed and fixedly mounted on the box body 1 by screws, so that it is convenient to repair and replace the parts inside the box body through the inspection ports.

[0045] In summary, when the device is used, the motor 320 is started, and the motor 320 drives the fan 310 to operate. Under the action of the fan 310, the air with dust will enter the filter space 5 through the air inlet pipe and the air inlet 130. Under the filtering action of the filter cartridge 510, the dust in the air will adhere to the outer surface of the filter cartridge 510, and the air will enter the blowing space 4 through the filter cartridge 510, and then enter the exhaust air through the fan 310. Finally, the filtered air will be discharged to the outside air through the exhaust port; when the pulse solenoid valve 401 is opened, the compressed air in the air bag 402 will pass through the pulse solenoid valve 401. The solenoid valve 401 blows toward the corresponding filter cartridge 510, and the diverter block 511 and the blades 512 can disperse the gathered airflow to the surroundings. The dispersed airflow will blow toward the side wall of the filter cartridge 510, thereby blowing off the dust on the side wall of the filter cartridge 510. At the same time, under the blowing of the airflow, the blades 512 will drive the corresponding filter cartridge 510 to rotate rapidly through the connecting block 513. The rapidly rotating filter cartridge 510 will generate centrifugal force to further separate the adhered dust from the filter cartridge 510. Finally, due to the rotation of the filter cartridge 510, the brush 6 can also brush the outermost layer of dust from the filter cartridge 510 into the ash hopper 530.

[0046] The technical solution of the present application is to arrange filter cartridges, fans and other structures in the box body so that the dusty air from the outside can enter the box body, and is filtered through the filter cartridges under the action of the fan, and finally the filtered air can be discharged back into the outside air. The arrangement of the blowing component can automatically clean the dust adhering to the filter cartridge, thereby ensuring that the filter cartridge has a better filtering effect and extending the service life of the filter cartridge.
