Tensionable linear sieve

Abstract

The invention discloses a tensioning type linear sieve plate belonging to the field of vibratory screening machinery and overcoming the defects of low aperture ratio, poorer elasticity, easiness in pore blockage and the like of the traditional sieve plate. A sieve plate frame comprises a left sieve plate frame and a right sieve plate frame which are fastened together through a tensioning connecting device; two ends of the sieve plate frame are provided with grating fixing beams; the middle of the sieve plate frame is provided with a grating supporting beam, and a supporting positioning strip is arranged on the grating supporting beam; and a grating is a linear grating, one end of the linear grating is locked through a locking member and sequentially fixed on the grating fixing beam at twoends of the sieve plate frame in a reciprocating manner, the middle of the linear grating is arranged on the supporting positioning strip on the grating supporting beam, and the other end of the linear grating is locked through the locking member. The sieve plate disclosed by the invention has the characteristics of high aperture ratio, good elasticity, high sieve-penetrating ratio, difficulty inpore blockage and convenience for tensioning, replacing and maintaining, and is especially suitable for sieving wet and sticky fine particular materials.

Description

technical field [0001] The invention belongs to the field of vibrating screening machinery, and mainly relates to a tensionable linear sieve plate which has high porosity and good elasticity and is suitable for screening viscous and wet fine particle materials. Background technique [0002] The sieve plate is the main screening part of the vibrating screen, and its performance directly affects the processing capacity of the vibrating screen and the screening effect of materials. At present, the screening of viscous and wet fine particle materials is an urgent problem to be solved in the screening industry. Because the sticky and wet fine particle materials are bonded to each other or attached to the screen under the action of water and clay, it is difficult to loosen. The fine sieve holes will be gradually blocked, which will reduce the effective sieving area of ​​the vibrating screen, resulting in the deterioration of the sieving process and a sharp drop in sieving efficie...

AI Technical Summary

Problems solved by technology

The fine sieve holes will be gradually blocked, reducing the effective sieving area of ​​the vibrating screen, resulting in deterioration of the sieving process and a sharp drop in sieving efficiency

At present, sieve plates for screening such materials, such as elastic rod sieve plates, movable rod sieve plates, comb-teeth sieve plates, self-cleaning bar sieve plates and stepped sieve plates, etc., all have the disadvantages that the sieve holes are not too small and the opening rate is low. Disadvantages such as low, poor elasticity of the sieve plate and easy plugging
