Washable and reusable air filter element

Abstract

The invention discloses a washable and reusable air filter element. According to the technical scheme, the washable and reusable air filter element comprises an upper end cap and a lower end cap, wherein a skeleton is arranged between the upper end cap and the lower end cap; a composite filter layer is fixed on the outer side of the skeleton; and a sealing ring for sealing the composite filter layer is arranged above the upper end cap. The filtering efficiency of the air filter element is obviously higher than that of paper air filter element, the initial resistance of the air filter element is obviously lower than that of the paper air filter element, the air filter element can be reused after being cleaned, and the service life of the air filter element is far greater than that of the paper air filter element.

Description

technical field [0001] The invention relates to an air filter element, in particular to a washable and reusable air filter element suitable for air filtration in the mechanical field. Background technique [0002] At present, domestic automobile engine air filter elements, construction machinery air filter elements, air compressor air filter elements, gas generator set air filter elements, self-cleaning air filter elements and other cylindrical air filter elements mostly use wood pulp fiber filter paper, which is not easy to clean when the dust clogging reaches the service life Or it cannot be cleaned at all, consuming a large amount of tree resources, resulting in a great waste of resources. Under the environment with increasing pressure on environmental protection, there is an urgent need for a filter element that does not use wood pulp fiber filter paper and can be used for repeated cleaning. Fill the gap in the market. [0003] However, the existing patents "A Nano-wash...

Problems solved by technology

[0002] At present, domestic automobile engine air filter elements, construction machinery air filter elements, air compressor air filter elements, gas generator set air filter elements, self-cleaning air filter elements and other cylindrical air filter elements mostly use wood pulp fiber filter paper, which is not easy to clean when the dust clogging reaches the service life Or it cannot be cleaned at all, consuming a large amount of tree resources, resulting in a great waste of resources. Under the environment with increasing pressure on environmental protection, there is an urgent need for a filter element that does not use wood pulp fiber filter paper and can be used for repeated cleaning. Fill the gap in the market

[0003] However, the existing patents "A Nano-washing Air Filter Element" (Authorized Announcement No. CN206299486V) and "A Nanofiber Coated Super-hydrophobic Self-cleaning Air Filter Element and Manufacturing Method" (Application Announcement No. CN106377948A) etc., the above-mentioned technologies are still It is necessary to use wood pulp fiber filter paper as the base material, and it is impossible to clean the front and back of the filter layer with water or the front and back blowing of compressed air, and the processing technology of the above-mentioned patent is complicated, and it is not easy to mass-produce and use
