Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to a self-cleaning air filter. Background Art

[0002] Air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It purifies the low-dust air and sends it into the room to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room. It is usually used in biopharmaceuticals, hospitals, airport terminals, human settlements and other places. The general ventilation filter has a wider range of uses. The microelectronics industry, coating industry and food and beverage industry all have needs. In other words, the filter is only a means to achieve the goal of cleanliness. In the existing aerodynamic devices, there are two types of systems used to purify the air filled with fine particles. One is dynamic, that is, self-cleaning, and the other is static without self-cleaning function.

[0003] However, most of the existing air filters do not have a self-cleaning function. Since the air filters absorb impurities in the air for a long time, the filter components often adhere to more impurities. If these impurities cannot be cleaned in time, the use effect of the air filter will be reduced. When the filter components inside the air filter need to be cleaned, the filter components are usually required to be cleaned and maintained by staff on a regular basis, which increases manpower and material costs, reduces the use effect of the air filter, and is inconvenient to use.

[0004] Therefore, those skilled in the art provide a self-cleaning air filter to solve the problems raised in the above background technology. Utility Model Content

[0022] The inner wall of the dust collection shell 201 is fixedly connected with a dust collection filter plate 211, the upper surface and the left side of the outer shell 1 are respectively movably hinged with a first sealing door 202 and a second sealing door 203, the inner wall of the outer shell 1 is fixedly connected with a support plate 210, the upper surface of the support plate 210 is respectively fixedly connected with two vacuum pumps 205 and two blowing pumps 208, the front of the outer shell 1 is movably hinged with an inspection door 3, the front of the inspection door 3 is fixedly connected with a pulling handle 4, through the inspection door 3 and the pulling handle 4, the interior of the outer shell 1 can be easily inspected, thereby increasing the use effect.

[0023] The output end of each vacuum pump 205 and the output end of the blowing pump 208 are respectively fixedly connected with an exhaust pipe 207 and an exhaust pipe 209. The end of each vacuum pipe 207 away from the vacuum pump 205 passes through the dust suction shell 201 and extends to the interior of the dust suction shell 201. The outer surface of each vacuum pump 205 is fixedly connected with a base 7. The bottom surface of each base 7 is fixedly connected to the upper surface of the support plate 210. Through the base 7, it is convenient to further increase the connection of the vacuum pump 205 to prevent shaking.

[0024] The bottom end of each blowing pipe 209 passes through the support plate 210 and extends to the bottom of the support plate 210. The outer surfaces of the two exhaust pipes 207 are fixedly connected to two connecting plates 8. The upper surface of each connecting plate 8 is fixedly connected to the bottom surface of the support plate 210. Through the connecting plate 8, the stability of the exhaust pipe 207 can be conveniently ensured, effectively increasing the stabilization effect.

[0025] The bottom ends of the two blowing pipes 209 are fixedly connected to a sealing shell 212, and the bottom surface of the sealing shell 212 is fixedly connected to a number of identical air outlet heads 213.

[0026] The working principle of the utility model is as follows: when in use, the suction pump 205 and the blowing pump 208 are connected to the power supply. When it is necessary to filter the air dust through the air filter, the air inside the dust suction shell 201 is first extracted by the cooperation of the suction pump 205 and the suction pipe 207. The suction force extracts the air through the dust suction filter plate 211 and the dust suction shell 201. The impurities and dust in the air are filtered and adsorbed by the dust suction filter plate 211, and the dust in the air is effectively filtered. When it is necessary to clean the dust suction filter plate 211, the air pump 208 and the blowing pipe 209 are first used to discharge the extracted air into the sealed shell 212. When the air inside the sealed shell 212 is squeezed to a certain extent, the air is discharged through the bottom air outlet 213. The dust on the surface of the dust filter plate 211 is directly dry-blown through the air outlet head 213. The air blown by the air outlet head 213 can blow off the dust impurities adhered to the surface of the dust filter plate 211, and the impurities on the surface of the dust filter plate 211 are effectively self-cleaned. Most air filters do not have a self-cleaning function, and the filter components need to be cleaned and maintained regularly by staff, which increases manpower and material costs and reduces the use effect of the air filter. If it is necessary to deeply clean the impurities on the surface of the dust filter plate 211, the first sealing door 202 and the second sealing door 203 are directly opened, and the dust filter plate 211 is directly flushed with an external water source. The flushed impurities flow to the bottom of the outer shell 1 through the dust collecting plate 206, thereby increasing the cleaning effect.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
