Hinge filtering component and filtering system

Abstract

The invention discloses a hinge filtering component and a filtering system. The hinge filtering component comprises an outer cylinder, an inner cylinder and a filtering layer, wherein a filtering material is folded into a corrugated layer encircling the exterior of the inner cylinder, thereby forming the filtering layer; the filtering material is composed of two layers of soft filtering net frames and a filtering film or filtering cloth clamped between the two layers of the soft filtering net frames; and all waved hinges of the filtering material are tightly wound on the inner cylinder along a same direction. The filtering system comprises the hinge filtering component. Two filtering modes of positive filtering and negative filtering can be realized by the hinge filtering component provided by the invention. The two filtering modes are alternatively used, so that a stressed direction of the filtering layer is variable. The positive filtering and the negative filtering are realized, so that a film-blocked phenomenon or an irrecoverable film deformation problem caused by long-term filtering along a same direction is avoided. In the filtering system provided by the invention, a process of halting and connecting an external water source is unnecessary and a backwash operation is simple.

Description

technical field [0001] The invention relates to a separator assembly, in particular to a flap filter assembly, and also to a filter system. Background technique [0002] With the continuous revolution of industry and the continuous improvement of living standards, the implementation of sustainable development strategy, the requirements for humanistic and ecological environment are getting higher and higher. Therefore, saving water resources, sanitation water and reducing water pollution are the primary strategic issues of the contemporary era, so it can solve industrial problems. The useful and effective filtration of sewage, domestic water, and industrial production water is an eternal research topic. Currently existing filtration devices mainly include membrane separation devices, vacuum drum filters, belt filters, plate and frame filters, and media filters. [0003] The membrane separation device uses the membrane as the separation medium. When there is a certain driving...

Problems solved by technology

[0011] Chinese Patent No. 200910258565.9 discloses a cylindrical filter assembly. All concentrated water layers and the inner cylinder are connected end to end in the order from outside to inside. The outer cylinder is provided with a concentrated water inlet, and the inner cylinder is provided with a concentrated water filter. At the outlet, the concentrated water flow channel is very long, and the filtration efficiency is lower as the concentrated water flows, which affects the overall filtration efficiency

It can only filter in one direction, and the filter can only use ordinary materials for support and turbulence

In particular, the sealing process at both ends of the filter assembly is difficult and easy to leak
