Problems solved by technology

[0006] In the traditional method of manufacturing the sealing layer of the planar hollow fiber membrane, the casting mold is composed of the end of the cylindrical shell of the filter element and the movable sealing cover. materials; secondly, the traditional method of making filter elements needs to seal the sealing ends of multiple hollow fiber membranes, which requires a lot of manual work and is not convenient for large-scale production
In addition, in the filter element made by the traditional method, the hollow fiber membrane tubes are distributed unevenly and irregularly on the surface of the water-producing end; the traditional filter element manufacturing method is also not suitable for manufacturing the sealing layer of the hollow fiber membrane filter element with a three-dimensional structure

Embodiment Construction

[0028] A method for manufacturing a sealing layer of a hollow fiber membrane filter element with a three-dimensional structure, the sealing layer (1) is cast from an adhesive material, and the opening ends of a plurality of hollow fiber membranes (2) pass through the sealing layer from the outer surface of the sealing layer To its inner surface, take the manufacture of a cylindrical three-dimensional sealing layer as an example, including the following steps:

[0029] (1) Make a casting mold. First make a mold (9) whose inner cavity is a cuboid, such as image 3 As shown, the length of the inner hollow cuboid is the perimeter of the cylindrical sealing layer, the width is the height of the sealing layer, and the height is the thickness of the sealing layer. Several through holes (10) are evenly distributed on the bottom of the mold. The horizontal serial number of the through holes is Dn, and the vertical serial number is Gn. The diameter of the through hole is smaller than ...

Abstract

The invention discloses a making method of a hollow fiber membrane filter element sealing layer with a three-dimensional structure. The sealing layer is formed by casting a bonding material, and opening ends of a plurality of hollow fiber membrane filaments penetrate through the sealing layer from the outer surface of the sealing layer to the inner surface of the sealing layer. The making method is characterized by comprising the following steps: casting the bonding material in a mould to form a planar hollow fiber membrane sealing layer; coiling and jointing one or more planar hollow fiber membrane sealing layers to form a three-dimensional hollow fiber membrane sealing layer. The making method has the advantages of reducing the labor capacity, saving the cost, increasing the efficiency and facilitating the large-scale production.

Description

technical field [0001] The invention relates to the manufacture of a hollow fiber membrane filter element, in particular to a method for manufacturing a sealing layer of the hollow fiber membrane filter element. Background technique [0002] Membrane separation technology is a separation technology widely used in the separation, concentration and purification of solutions or gaseous substances. The membrane wall is densely covered with micropores, the stock solution passes through one side of the membrane under a certain pressure, the solvent and small molecular solutes pass through the membrane wall to become the filtrate, and the macromolecular solutes are retained by the membrane to achieve the purpose of material separation and concentration. In the water purification industry, the technology of using hollow fiber membranes to make filter elements to filter and purify water quality is widely used. [0003] There are two types of known hollow fiber membrane filter elemen...
