Multi-stage filtering split type air filter and working method thereof

Abstract

The invention provides a multi-stage filtering split type air filter and a working method thereof, and relates to the technical field of air cleaners. The multi-stage filtering split type air filter comprises a filter body, the filter body comprises a filter shell, and two compressible filter element assemblies which are oppositely distributed are contained in an inner cavity of the filter shell; and each filter element assembly is composed of a plurality of filter element layers capable of elastically stretching out and drawing back in the length direction of the filter shell, a pressure applying assembly capable of intermittently applying pressure in one direction is arranged between every two adjacent filter element assemblies, each pressure applying assembly comprises a pressure applying plate capable of reciprocating in the length direction of the filter shell, and the pressure applying plates make elastic contact with the filter element assemblies. The filter element assemblies are compressed and recovered to drive the filter element layer to move, so that the filter element layers can be cleaned, dust attached to the surfaces of the filter element layers is reduced, the filter element layers are cleaned, and the cleaning effect of the filter element layers is improved.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to a multi-stage filter split air filter and a working method of the multi-stage filter split air filter. Background technique [0002] An air filter is a filter, also known as an air filter cartridge or an air filter element. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operating rooms and various precision operating rooms. [0003] After the existing air filter is used for a long time, a large amount of dust particles will be filtered out on the filter core layer. If these dust particles continue to adhere to the core layer, the filtering effect of the core layer will be reduced, the service life will be reduced, and the dust will fall off. Then it will fly around inside the filter, reducing air quality and practicality. Contents of the invention [0004] Aiming at the deficiencies of the prio...

Problems solved by technology

[0003] After the existing air filter has been used for a long time, a large amount of dust will be filtered out on the filter core layer. If these dust chips continue to adhere to the core layer , will reduce the filtering effect of the core layer and reduce the service life, and after falling off, it will fly randomly inside the filter, reducing air quality and reducing practicability
