Filter element and manufacturing method thereof

Abstract

The invention discloses a filter element and a manufacturing method thereof. The filter element comprising a filter element body, wherein the filter element body comprises a framework fiber layer; a rough filtration fiber layer is arranged on the inner side of the framework fiber layer; an adsorption fiber layer is arranged on the inner side of the rough filtration fiber layer; a refined filtration fiber layer is arranged on the inner side of the adsorption fiber layer; a first fixing plate and a second fixing plate are arranged on the two sides of the two ends of the filter element body correspondingly. Locking plates are fixedly connected to the two ends of the first fixing plate and the two ends of the second fixing plate correspondingly. A locking rod is inserted between the two locking plates; a connecting rod is fixedly connected to the outer side walls of the first fixing plate and the second fixing plate; a threaded rod is inserted into the connecting rod in threaded mode, oneend of the threaded rod is rotationally connected with a positioning plate, and one side of the positioning plate abuts against the outer wall of the filter element body; collapse and deformation arenot likely to happen, the filtering precision is high, activated carbon fibers can effectively kill bacteria, the purifying effect is improved, the filter element is stable in the using process, and the filtering effect is improved.

Description

technical field [0001] The invention relates to the field of filter-related products, in particular to a filter element and a manufacturing method thereof. Background technique [0002] The filter element is the heart of the filter, as the name implies, it is the filter element. The main principle of the filter element is also the main principle of the filter. It is the purification equipment needed to purify the original ecological resources and reuse the resources. The filter element is generally used in oil filtration, water filtration, air filtration and other filtration industries. Removing a small amount of impurities in the filter medium can protect the normal operation of the equipment or the cleanliness of the air. When the fluid passes through the filter element with a certain precision in the filter, the impurities are blocked, and the clean fluid flows out through the filter element. [0003] However, the existing filter elements are heavy in weight and high in ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing filter elements are heavy in weight and high in cost because they are formed by single radial winding after melting of single-component fibers, the fiber bonding is very loose, the gaps between the activated carbon fibers are large, and the adsorption efficiency of toxic substances is low. The fixed stability is not high, which affects the service life and has certain defects
