Problems solved by technology

[0002] The sieve plate used for coal water slurry filtration is generally a single-layer filter. If the mesh is too small, the sieve plate is easy to block and the filtration speed is slow. If the mesh is too large, the residual particles in the coal water slurry will be relatively large, which will affect the water quality. Coal slurry quality

Abstract

The invention discloses a sieve plate. The sieve plate comprises a first filter plate and a second filter plate. The first filter plate is disposed above the second filter plate with a distance between the first filter plate and the second filter plate being 1-2 cm. The right ends of the first and second filter plates are connected through a connecting plate and the left ends of the first and second filter plates are connected through a connecting plate. The first filter plate is provided with first filter holes which are inverted cone type filter holes. The second filter plate is provided with second filter holes which are cone type filter holes. The hole diameter of the upper ends of the second filter holes is smaller than the hole diameter of the lower ends of the first filter holes. The first filter plate removes large particles in coal water slurry and the hole diameter of the upper ends is large, so that large particles are stopped and small particles flows rapidly into the lower second filter plate. The filter holes on the upper end of the second filter plate are small and can further filter the coal water slurry.

Description

technical field [0001] The invention relates to a sieve plate, in particular to a sieve plate used for a coal-water slurry vibrating screen. Background technique [0002] The sieve plate used for coal water slurry filtration is generally a single-layer filter. If the mesh is too small, the sieve plate is easy to block and the filtration speed is slow. If the mesh is too large, the residual particles in the coal water slurry will be relatively large, which will affect the water quality. coal slurry quality. Contents of the invention [0003] The invention relates to a sieve plate, which can ensure the filtration speed and the quality of coal-water slurry. [0004] To achieve this purpose, the structure adopted in the present invention is: a sieve plate, comprising a first filter plate and a second filter plate, the first filter plate is arranged above the second filter plate, the first filter plate and the second filter plate The plates are parallel to each other, the two...
