Abstract

The utility model relates to a high-efficiency sieve bend, which comprises a sieve bend body 1, a protecting sieve 2 and a bottom sieve plate 3. The high-efficiency sieve bend is characterized in that the protecting sieve 2 with larger sieve holes is additionally arranged on the bottom sieve plate 3, fine particles, media and coal slime, whose sizes are smaller than those of the sieve holes, can contact with the bottom sieve plate 3 better under the action of sieving of the protecting sieve 2, and thereby technological effect of the sieve bend is improved. Meanwhile, large particles with size larger than the sieve holes of the protecting sieve 2 cannot directly contact with the bottom sieve plate 3, and accordingly, the service life of the sieve bend is prolonged.

Description

A kind of efficient sieve bend

Affiliated technical field

The utility model relates to a kind of efficient sieve bend, a kind of sieve bend that has the two superimposed screen cloth of more specifically saying so.

Background technology

The sieve bend that uses is the individual layer screen cloth at present, and in use compass screen surface weares and teares easily, not only reduces the service life of sieve bend, and reduces the technological effect of its use.And by sieve bend being provided with the bigger protection screen cloth of upper strata sieve aperture; just can play a good protection to the bottom sieve plate; simultaneously because the filtration of upper strata protection screen cloth; making can better the contact bottom layer sieve plate less than fine grained, medium and the black water of upper strata screen mesh, thereby improves the technological effect that sieve bend is handled.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure and longer service life, the better efficient sieve bend of technological effect.

The purpose of this utility model can realize in the following manner: a kind of efficient sieve bend; comprise sieve bend material receiving box and double-deck screen cloth; it is characterized in that: on the bottom sieve plate of sieve bend, add the bigger catch net of one deck sieve aperture, increase the service life of sieve bend, improve the technological effect of sieve bend.

The utility model compared with prior art has following advantage: increase the bigger protection screen cloth of one deck sieve aperture on sieve bend bottom sieve plate, making can better the contact bottom layer sieve plate less than fine grained, medium and the black water of upper strata screen mesh, reduce the resistance of the saturating sieve of fine grained, medium and black water, thereby reach the purpose of improving the sieve bend technological effect; Particle greater than upper strata protection screen mesh size then can not directly touch the bottom sieve plate, improves the sieve bend purpose in service life thereby reach.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

As follows with reference to accompanying drawing: a kind of efficient sieve bend, this sieve bend comprise sieve bend body (1), protection screen cloth (2), bottom sieve plate (3).It is characterized in that: locate to set up the bigger protection screen cloth (2) of one deck sieve aperture at bottom sieve plate (3), filtration by protection screen cloth (2), make fine grained, medium and black water can better touch bottom sieve plate (3), thereby improve the technological effect of sieve bend less than the upper strata sieve aperture; Simultaneously because greater than the direct contact bottom layer sieve plate (3) of the bulky grain of protection screen cloth (2) screen size, thereby reach the purpose in service life of raising sieve bend.

Claims

1. efficient sieve bend, this sieve bend comprise sieve bend body (1), protection screen cloth (2), bottom sieve plate (3); It is characterized in that: locate to set up the bigger protection screen cloth (2) of one deck sieve aperture at bottom sieve plate (3).
