Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a metal powder sintered felt filter material. Background Art

[0002] A metal powder filter element is made by pressing multiple layers of metal mesh, with metal powder filled between the metal meshes to form a porous metal filter material with three-dimensional random channels. The metal powder filter element has the characteristics of large pore size, high filtration accuracy, high flow rate and high corrosion resistance. Metal felt is made of various metal fibers or wires and has a fine pore structure with intricate threads. It can be used in fields such as air filtration and liquid filtration. Existing filtering devices generally only use one filter material, that is, a metal powder filter element and a metal felt are used separately. Both metal powder filter elements and metal felt have certain advantages and disadvantages. For example, the advantage of the metal powder filter element is that it can effectively separate liquid and solid phases while ensuring high flux and long service life. However, its disadvantage is that its structure is relatively loose and prone to chipping, requiring regular replacement. The advantage of metal felt is that it has high filtration accuracy and good filtration performance, and can effectively filter impurities such as tiny particles and microorganisms. However, its disadvantage is that the filtration flux is small and the filter pores are easily blocked by large particles. Therefore, it is difficult to combine metal powder filter elements and metal felt in the current market. To this end, a metal powder sintered felt filter material is proposed to solve the above problems. Utility Model Content
