Abstract

The invention provides a cleanable filter which comprises an outer frame and a filter element, a filter channel is formed in the middle of the outer frame, an air inlet and an air outlet are formed intwo sides of the outer frame, the filter element comprises filter paper, a microporous membrane is arranged on the side, corresponding to the air inlet, of the filter paper, and a fixing strip is arranged on the side, corresponding to the air outlet, of the filter paper; the microporous membrane can block dust particles in the air outside the filter paper, so that the dust particles are preventedfrom invading the filter paper to influence the filtering effect; meanwhile, the microporous membrane has excellent waterproof and breathable properties, so that the filter element has the characteristic of cleanability, and the microporous membrane has a protection effect on the filter paper, so that the working efficiency of the filter after cleaning is basically not reduced; the fixing strip is arranged on the side, corresponding to the air outlet, of the filter paper, so that the supporting and fixing effects on the filter paper are guaranteed, and the dust containing effect is enhanced as no fixing strip is arranged on the side, corresponding to the air inlet, of the filter paper; and the filter element and the outer frame are of a detachable structure, the filter element can be repeatedly used after cleaned, the service life of the filter can be prolonged, and the replacement cost is reduced.

Description

technical field [0001] The invention relates to the field of filter equipment, in particular to a washable filter. Background technique [0002] With the continuous improvement of environmental requirements for products such as electronics and semiconductors, more and more air purification equipment has appeared. Among these air purification equipment, most of them need to use filters to remove dust from the air. The existing filters It is mainly divided into filters with clapboards and filters without clapboards. Compared with filters with clapboards, filters without clapboards have the advantages of small size, light weight, easy installation, stable efficiency, and uniform wind speed. The uniformity of dust holding prolongs the service life, so it is widely used in clean workshops with high environmental requirements. However, the filter element of the existing filter without partitions is generally disposable, cannot be cleaned and reused, has a short service life, and ...
