Description

Technical Field

[0001] The present application relates to the field of air filter devices, and in particular to a high-throughput self-cleaning air filter device. Background Art

[0002] The self-cleaning air filter uses multiple filter cartridges to filter dust in the air. However, the filtered dust will adhere to the filter cartridge, which will cause a layer of dust to form on the outer wall of the filter cartridge, thereby affecting the speed at which the air passes through the filter cartridge, thereby affecting the effect of the filter cartridge in filtering the air.

[0003] In the relevant technical field, some technical solutions adopt a back-blowing device in the filter cartridge, which blows out air to blow away the dust on the outer wall of the filter cartridge from the inside to the outside. However, after the back-blowing device blows away the dust, it is difficult to collect the dust in time, causing the filter cartridge to be quickly covered with dust again. Moreover, during back-blowing, the air is blown out from multiple filter holes on the filter cartridge. Then, the dust on the filter cartridge is only blown away at the filter holes, and the dust between the filter holes is difficult to be blown away. As a result, there is still a layer of dust on the outer wall of the filter cartridge. The dust in one place is blown away to form a depression, and the dust in the rest of the parts is easily filled in, making it difficult to ensure a good back-blowing effect. Utility Model Content

[0050] Workflow:

[0051] The air outlet 13 is connected to an external pipeline, and a pump body is arranged on the pipeline, so that the airflow passes through the air inlet 11, the filter chamber 12 and the air outlet 13 in sequence. When the gas passes through the filter chamber 12, the gas contacts the filter cartridge 3, so that the filter cartridge 3 filters the dust in the air, and the clean air is discharged to the outside through the filter chamber 12 and the air outlet 13.

[0052] After the filter cartridge 3 is used for a long time, dust will adhere to the outer surface of the filter cartridge 3, which will reduce the efficiency of air passing through the filter cartridge, thereby affecting the air circulation speed and the air filtering effect.

[0053] During use, the first drive motor 61 drives the first drive screw 62 to rotate, and the first drive screw 62 drives the support plate 64 to move through the first drive nut 63. The second drive motor 65 drives the second drive screw 66 to rotate, and the second drive screw 66 drives the sealing shell 41 to move through the second drive nut 67. The sealing shell 41 moves synchronously with the support plate 64.

[0054] First, the sealing shell 41 and the support plate 64 are moved to a row of filter cartridges 3, and then the lifting drive member 7 drives the connecting member 8 to move close to the filter cartridge 3 until the end of the connecting member 8 abuts against the mounting plate 2, so that the plurality of filter cartridges 3 are all located in the guide channel 81, and then the electric push rod 48 drives the push plate 42 to move downward, and the push plate 42 drives the first connecting pipe 43 to move downward, so that the first connecting pipe drives the first sealing plate 47 and the second sealing plate 49 to move to the inside of the filter cartridge 3, and the first sealing plate 47 and the second sealing plate 49 abut against the inner wall of the filter cartridge 3. Then the first air pump 46 blows air outward from the first connecting pipe 43 through the air inlet pipe 45, so that air is blown outward from the lower part of the first connecting pipe 43, and air is blown outward from the through hole between the first sealing plate 47 and the second sealing plate 49, so that the through hole between the first sealing plate 47 and the second sealing plate 49 can back-blow and clean the side wall of the filter cartridge 3, and the blowing force of the air blowing outward is increased by reducing the air space, thereby increasing the back-blow effect. As a result, the dust on the filter cartridge 3 will be blown into the guide channel 81 and will be sucked away by the fourth connecting pipe 55 in the guide channel 81 and sucked into the dust collection box 51, thereby achieving dust collection.

[0055] After collection, the air pump 911 inflates the multiple flexible bags 9 through multiple inflation tubes 912 until the flexible bags 9 contact the outer wall of the filter cartridge 3, and then the lifting drive 7 moves the support plate 64 and the connecting member 8 downward, so that the flexible bags 9 also move downward. The flexible bags 9 move down and leave the filter cartridge 3, thereby enabling the flexible bags to clean the filter cartridge 3 by physical contact, and to clean the dust on the outer wall of the filter cartridge 3 that has not been blown back down.
