Air filter plate manufactured by sand and method for manufacturing filter plate through sand

Abstract

The invention discloses an air filter material plate synthesized by sand and a method for manufacturing the filter material plate through sand. The filter material plate is used for filtering fluid to be filtered and comprises a filter body. The filter material body is formed by pressing sand. The manufacturing method comprises the steps that 1, sand is heated to be at the preset temperature; 2, a binding agent is prepared, the sand and the binding agent are proportionally mixed according to different filter requirements, and a mixture is formed; 3, the mixture is placed in a mold and pressed; 4, the mixture is stopped from being pressed after the mixture is cooled, and a filter material body is formed; 5, the filter material body is placed at the position where fluid to be filtered passes to be used as the filter material plate. The manufactured filter material plate can be used for various environments and devices needing air filtration, the air filtration effect is not affected by air dust and haze concentration, the air filtration effect is better compared with any filter material on the current national market, adsorption blockage is avoided, cyclic regeneration utilization is achieved, and social environment garbage pollution is completely eradicated.

Description

technical field [0001] The invention relates to the technical field of air filtration, in particular to a method for using natural sand to synthesize an air filter material board and using sand to manufacture a filter board. Background technique [0002] At present, most of the air filter materials used at home and abroad are filter materials such as mineral wool, fiber weft synthesis, and metal mesh. This technology fills the blank of filter materials made of sand in the world and at home, and is a new type of filter material that is energy-saving, environmentally friendly, pollution-free, recyclable and reusable. [0003] Prior art Chinese patent CN101185818A discloses an air filter material, which is an air filter material formed by laminating the air inflow layer and the air outflow layer. Its average flow pore size is 20-40 μm, and the minimum pore size is 204-3.8 μm And the maximum pore size is below 80μm, and the air inflow layer has a fiber content of 55-100g / m 2 T...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that most of the filter materials in the prior art are composed of fibers and wefts, the filter effect is not good, and the filter material is easily blocked by the filtered fluid filtrate, and it is not easy to clean or clean after the blockage. The technical problems of increasing the energy consumption of the filtering equipment, short service
