Folding filter element for tap water treatment

Abstract

The invention relates to a folding filter element for tap water treatment. The folding filter element comprises a telescopic cylinder. An end cover is arranged at the top end of the telescopic cylinder, and a base is arranged at the bottom end of the telescopic cylinder. A water outlet is formed in the axial lead position of the end cover. A water inlet is formed in the base. A cylindrical telescopic filter element is arranged in the telescopic cylinder. A cylindrical folding filter element is arranged in the telescopic filter element, and the folding filter element is of a wave structure capable of stretching and retracting in the axial direction. A PES film is arranged between the telescopic filter element and the folding filter element. The top end of the folding filter element is detachably and fixedly connected to the end cover, and the bottom end of the folding filter element is detachably and fixedly connected to the base. The top end of the telescopic filter element is detachably and fixedly connected to the end cover, and the bottom end of the telescopic filter element is detachably and fixedly connected to the base. The water inlet is formed in the outer side of the telescopic filter element, and the water outlet is formed in the inner side of the folding filter element. The required length of the folding filter element can be effectively adjusted, and different use requirements can be met.

Description

technical field [0001] The invention relates to a filter element for water treatment, in particular to a folded filter element for tap water treatment. Background technique [0002] The microporous membrane pleated filter element is mainly characterized by high retention rate, high flow rate, low pressure difference and wide chemical compatibility; the production process adopts unique hot-melt welding processing technology, without any adhesives, and no foreign matter is released. Widely used, but the length of the current pleated filter element is fixed and cannot be adjusted. It needs corresponding space to match its length for installation, and the length cannot be adjusted according to the actual situation of the user. The use has limitations. Contents of the invention [0003] Aiming at the existing deficiencies, the invention provides a folded filter element for tap water treatment. [0004] The technical solution adopted by the present invention to solve the techni...
