Mesh bag free corrugated filter board

Abstract

The invention discloses a mesh bag free corrugated filter board. The mesh bag free corrugated filter board is prepared from 316L stainless steel material, and is designed to be a fan-shaped plate; thefan-shaped plate is uniformly provided with a plurality of phi 0.8mm pores, the distance between adjacent pores is controlled to be 1.6mm, the surface of the fan-shaped plate is provided with wave shaped patterns, the vertical distance of a wave peak to a corresponding wave bottom of the wave patterns on the surface of the fan-shaped plate is controlled to be 8 to 12mm, the distance between eachpair of adjacent wave peaks is controlled to be 32 to 40mm, the peripheral arc corresponding central angle of the fan-shaped plate is controlled to be 15 to 25 DEG. According to the mesh bag free corrugated filter board, the surface of the mesh bag free corrugated filter board is provided with a sieve plate with the phi 0.8mm pores with a pore distance of 1.6mm, so that a technical problem that filtering function can be achieved only through providing the fan-shaped plate with a mesh bag is solved, and increased cost and influences on production caused by changing of the mesh bags are avoided. According to the mesh bag free corrugated filter board, compared with a filter board with a mesh bag, when the disc diameter is the same, the filtering area is increased by 20% or larger, and the production capacity is increased by 20% or larger.

Description

technical field [0001] The invention relates to the field of papermaking machinery, in particular to a bagless corrugated filter plate for a disc filter. Background technique [0002] After years of research and innovation, the disc filter used in the papermaking industry has gradually changed from the original mesh bag type to the fan-shaped plate type without mesh bag. The main component of the fan-shaped plate is the corrugated filter plate without mesh bag, which has been widely used. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a kind of corrugated filter plate without mesh bag, which solves the technical problem that the filter function can only be realized by setting mesh bag on the fan-shaped plate, and overcomes the difficulty of replacing the mesh bag. Incurred costs and problems affecting production. [0004] In order to solve the above technical problems, the present invention adopts the following...

Problems solved by technology

[0003] The technical problem to be solved in the present invention is to provide a kind of corrugated filter plate without mesh bag, which solves the technical problem that the filter function can only be realized by setting mesh bag on the fan-shaped plate, and overcomes the difficulty of replacing the mesh bag. Incurred costs and problems affecting production

[0005] The present invention adopts the above-mentioned technical solution of the corrugated filter plate without mesh bag, which is made of a sieve plate with Φ0.8mm holes on the surface and a hole spacing of 1.6mm, which solves the technical problem that the filter function can only be realized by setting mesh bags on the fan-shaped plate. It overcomes the cost of replacing the mesh bag and the problem of affecting production. Using this kind of corrugated filter plate without mesh bag, the filter area increases by more than 20% compared with the case of using the mesh bag under the condition of the same disc diameter. Can increase production capacity by more than 20%
