Embodiment Construction

[0044] Combine below Figures 1 to 3 The given examples further illustrate the present invention, but the examples do not constitute any limitation to the present invention.

[0045] A kind of novel metal film filter material described in this embodiment, see Figures 1 to 3 , with 321 stainless steel wire mesh 1 as the material, the metal mesh is superimposed by 8 layers, vacuum sintered, and the meshes of each layer of the sintered mesh of the metal film mesh superimposed structure are interlaced to form a uniform structure of the metal film filter material.

[0046] The pre-filtration water inlet channel 2 of the metal film filter material is placed at the lower end of the metal film filter material, and the filtered water outlet channel 3 is located on the right side of the metal film filter material.

[0047] The metal film protective net 4 is placed on the periphery of the metal film filter material.

[0048] The metal film layer 5 is fixed by the metal film fixing end...

Abstract

The invention relates to a water filtration filter material, in particular to a novel metal film filter material and a preparation method and application thereof. The novel metal film filter material is made of stainless steel wire meshes, the wire meshes are subjected to multilayer overlaying and vacuum sintering, mesh holes of all layers of a metal film mesh overlay structure sintered mesh are mutually staggered, and the metal film filter material with the uniform structure is formed. According to the novel metal film filter material and the preparation method and application thereof, the problems that a traditional sewage filtration filter material cannot conduct effective filtering separation on low molecular weight organic matter, tiny suspended solids and objects with small particle sizes, and water subjected to conventional treatment cannot meet the water quality index requirement of state stratum reinjection water, inland exterior drainage and drinking water of residents are solved. The metal film filter material is widely applied to fine filtering equipment, high in grain boundary corrosion resistance requirement, of wild outdoor machines in chemical, coal and petroleum industries or heat-resistant parts of building materials and parts difficult in heat treatment and fine filtering equipment of the drinking water of the residents.

Description

technical field [0001] The invention relates to a filter material for water filtration, in particular to a novel metal film filter material and its preparation method and application. Background technique [0002] At present, the filtration treatment of sewage and drinking water is roughly divided into two stages: one is the conventional treatment stage of sewage and drinking water, namely: the primary filtration stage and the secondary filtration stage of sewage and drinking water, and the primary and secondary filtration stages are also called coarse Filtration stage; the second is the stage of fine filtration of sewage and drinking water, namely: three stages of filtration of sewage and drinking water. The filter media in the conventional filtration stage of sewage and drinking water generally use pebble filter media, anthracite filter media, walnut shell filter media, modified fiber ball filter media, fiber bundle filter media, quartz sand filter media, walnut shell + mo...
