Example Embodiment

[0010] In order to further describe the technical solution of the present invention, a detailed description will be given below in conjunction with the accompanying drawings and embodiments of the specification.

[0011] In the present invention, a layer of elastic support grids are attached to the upper and lower sides of the plate filter membrane, which are folded into an arc-shaped folded filter membrane 3 with a folding machine, and the two ends of the folded filter membrane are bonded together to form a cylindrical shape. , Use the inner layer of stainless steel mesh 2 and the outer layer of stainless steel mesh 4 to fix the folded filter membrane 3, and finally use the filter element to fix the head 1 to seal and fix the top and bottom ends of the cylindrical folded filter membrane 3, as shown in Figure 1. The cylindrical pleated filter element shown. If it is normal temperature water filtration, use glass mesh as the supporting grid; if the water temperature is higher than ...

Abstract

The invention provides a production method of a high filtration flux folded filter core, and belongs to the technology field of water treatment. The production method comprises the following steps: a layer of elastic supporting grid is respectively attached to the two side surfaces of a plate type filter film, a folding machine is used for folding the filter film into an arc-shaped filter film, the both ends of the filter film are bonded together to form a shape of cylinder, an inner layer of stainless steel net and an outer layer of stainless steel net are used for reinforcing and shaping the filter film, a filter core fixed seal is finally used for sealing and fixing the top end and the bottom end of the cylindrical filter film, thereby making the cylindrical folded filter core. The elastic roles of the supporting grids can fold the filter film into the shape of arc, thereby avoiding dead angles caused by the prior folding shape and greatly increasing the filtration flux of the filter film.

Description

Technical field: [0001] The invention relates to a water treatment device, in particular to a method for making a folded filter element with high filtration flux. Background technique: [0002] At present, most of the filter elements used for water treatment at home and abroad are folded cartridge filters, which can be divided into polymer membrane filter elements and metal membrane filter elements according to the material of the filter element. Among them, the folded shapes of the folded filter element are: pleated shape, W corrugated shape, zigzag shape, corrugated shape, etc., and the common point is that they all have an angular structure. The problem with these folded filter elements during use is that when the filter element is used for water treatment for a long time, pollutants will gather at the folded corners of the filter membrane, making the filter membrane easily polluted and causing a decrease in the filtration flux; These folded shapes will make the effectiv...
