Abstract

The utility model discloses a sieve sheet of a grinder. The sieve sheet comprises a sieve sheet body, wherein the sieve sheet body is in step-shaped distribution, side ribs are arranged at the two sides of the sieve sheet body, the side ribs are vertical to the sieve sheet body, and convex ribs are fixed between the side ribs. Sieve meshes are arranged at a plurality of planes, therefore, the sieved material does not easily block the sieve meshes; the convex ribs are arranged between the side ribs, therefore, the sieve sheet is easy to pull out from the fixing devices arranged at the two sides of the sieve sheet; moreover, the sieve surface is not easy to collapse, thereby greatly improving the sieving efficiency.

Description

Pulverizer sieve sheet

Technical field

The utility model relates to a kind of screening plant, particularly relates to a kind of pulverizer sieve sheet.

Background technology

The sieve sheet that uses now generally all is in one plane; Have certain sieve aperture according to specific putting in order, the problem that such sieve plate exists, the one, percent opening is lower; The material that is sized in addition sticks into sieve aperture easily; Stop up sieve aperture, influence screening efficiency, this type problem is more outstanding in bentonite is pulverized; In the design of sieve aperture,, cause bentonite in sieve aperture, to stop up so more easily because sieve aperture two ends size is consistent.In addition, the limit muscle of sieve sheet is equal with compass screen surface, in bentonite pulverizing process, because load is prone to from its both sides fixture extraction the sieve sheet, causes the compass screen surface waist that collapses, and influences its result of use.

Summary of the invention

The purpose of the utility model provides a kind of sieve plate of difficult obstruction sieve aperture, solves the unreasonable technical problem of bringing because of the sieve chip architecture, and its structure is fixed, and improves service efficiency.

To achieve these goals, the technical scheme that the utility model adopts is: a kind of pulverizer sieve sheet comprises sieve sheet body; Said sieve sheet body is step-like distribution; Be provided with the limit muscle in sieve sheet body both sides, the limit muscle is vertical with sieve sheet body, is fixed with convex tendon between the muscle of limit.

As preferably, be uniformly distributed with round sieve and bar shaped screen hole on the sieve sheet body, and adjacent two row's sieve aperture dislocation are arranged.

As preferably, said sieve aperture is the little conical through-hole of the big end of an end, and the small end hole face of sieve aperture is a working face.

Compared with prior art, the advantage of the utility model is: sieve aperture is arranged in a plurality of planes, and the material that is sized is difficult for stopping up sieve aperture; Be provided with convex tendon between the muscle of limit, thereby make the sieve sheet be difficult for extracting out from its both sides fixture, compass screen surface is difficult for the waist that collapses, and has improved screening efficiency greatly.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the cross-sectional structure sketch map of conical through-hole among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Consult Fig. 1, Fig. 2, a kind of pulverizer sieve sheet comprises sieve sheet body 1, and said sieve sheet body 1 is step-like distribution, is provided with limit muscle 2 in sieve sheet body 1 both sides, and limit muscle 2 is vertical with sieve sheet body 1, is fixed with convex tendon 3 between the limit muscle 2; Be uniformly distributed with round sieve and bar shaped screen hole on the sieve sheet body 1, and adjacent two row's sieve aperture dislocation are arranged; Said sieve aperture is the little conical through-hole 4 of the big end of an end, and the small end hole face of sieve aperture is a working face.

The described sieve sheet of the utility model body 1 is step-like, and sieve aperture is distributed on the Different Plane, the sieve aperture interlaced arrangement; In bentonitic screening process; When bentonite snapped in sieve aperture, through the vibration of sieve sheet body 1, bentonite just can go out to eject from sieve aperture; Can avoid stopping up sieve aperture, improve the screening efficiency of screening plant; Be provided with convex tendon 3 between the limit muscle 2, thereby make sieve sheet body 1 be difficult for extracting out from its both sides fixture, compass screen surface is difficult for the waist that collapses, and guarantees safe in utilization.

Claims

1. a pulverizer sieve sheet comprises sieve sheet body, and it is characterized in that: said sieve sheet body is step-like distribution, is provided with the limit muscle in sieve sheet body both sides, and the limit muscle is vertical with sieve sheet body, is fixed with convex tendon between the muscle of limit.

2. based on the described pulverizer sieve of claim 1 sheet, it is characterized in that: be uniformly distributed with round sieve and bar shaped screen hole on the sieve sheet body, and adjacent two row's sieve aperture dislocation are arranged.
