Abstract

The utility model relates to a screen cloth which is provided with a screen cloth plate. The screen cloth plate is provided with a plurality of V-shaped conical surfaces and a plurality of screen cloth meshes in an aligned-array-type mode. Edges of the screen cloth meshes are intersecting line cambered surfaces which are arranged on the V-shaped conical surfaces.

Description

A kind of screen cloth

Technical field

The utility model relates to a kind of single-shaft shredder and tears up the screen cloth that the film rear film filters, its be specifically related to a kind of in equal aperture the more reliable screen cloth smoothly of broken film punishment in advance.

Background technology

At present, as shown in Figure 1, structural representation for existing screen cloth, it ' is made of with sieve screen apertures 2 ' sieve plate smooth surface 1, sieve screen apertures 2 ' is generally circular port, diamond hole and cruciform vent, in film crushing equipment manufacture of environmental protection industry, screen cloth has become requisite vitals, but the putty with regard to screen cloth, get stuck, the correlation techniques such as bridging but do not have larger development for many years always, even change in a large number the size and shape of sieve screen apertures, also exist following problem: diamond hole, it is more smooth and easy that the cruciform vent screen cloth is crossed elongated film material than circular port screen cloth, output also can be suitable raising, but the film after the fragmentation is unrestrained with random form, still has the possibility of bridging putty.Add the large aperture and be the effective ways that solve putty, but after strengthening mesh size, whether broken film quality (broken film size) is up to standard also is a unknown number.Nowadays the nearly all sieve plate surface of the screen cloth in this field still is the plane putty, does not also carry out improved from the sieve plate surface.So be badly in need of now addressing the above problem.

Summary of the invention

For the problems referred to above, the purpose of this utility model propose a kind of use reliable, punishment in advance is smooth and easy, the screen cloth of good looking appearance.

Technical solution of the present utility model is as follows:

A kind of screen cloth, it is provided with a sieve plate, described sieve plate is provided with a plurality of sieve screen apertures, on the described sieve plate array be provided with many V-type conical surfaces, the edge of described sieve screen apertures is the intersection cambered surface, described intersection cambered surface is located on the V-type conical surface.

Owing to having adopted the appeal technical scheme, a kind of screen cloth of the utility model is realized processing by a kind of simple technique, reduced greatly the possibility of broken film bridging putty, and its technique is simple, and handling ease is suitable for extensive popularization.

Description of drawings

Fig. 1 is the overall structure schematic diagram of existing screen cloth.

Fig. 2 is the structural representation of a kind of screen cloth of the utility model.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in detail.

As shown in Figure 2, be the structural representation of a kind of screen cloth of the utility model, it is provided with a sieve plate 1, and array is provided with many V-type conical surfaces 2 and a plurality of sieve screen apertures 3 on the described sieve plate 1, the edge of described sieve screen apertures 3 is intersection cambered surface 4, and described intersection cambered surface 4 is located on the V-type conical surface 2.

When a kind of screen cloth of processing the utility model, at first sieve plate tubing is cut into required arcuate shape, only need after the punching workpiece is placed the enterprising driving processing of lathe, car becomes the shape of the utility model screen cloth to get final product.

A kind of screen cloth of the utility model does not change the shape and size of sieve screen apertures 2 under the prerequisite that the up to standard or broken film size of broken film quality meets the demands, only need to change the thickness of sieve plate 1, carry out again the car V-shape conical surface 3 of array on sieve plate 1 surface, make screen cloth 1 plate surface be non-smooth flat, and be the V-shape conical surface 3 and intersection cambered surface 4, even this V-shape conical surface 3 runs into the bridging putty with intersection cambered surface 4, shape behind its putty also can be V font windrow, the windrow of this shape is because the little at an upper portion thereof weight of contact area on the putty of bottom and sieve plate surface when reaching certain, can automatically be pressed in the sieve screen apertures because conducting oneself with dignity, secondly the rotor blade of single-shaft shredder also is V-shape, and V-shape conical surface engagement lucky and screen cloth has also greatly reduced the possibility of broken film bridging like this when the rotor rotation is broken.

The utility model is only illustrated explanation with above-described embodiment; the structure of each parts, setting position and connection thereof all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.

Claims (1)

1. screen cloth, it is provided with a sieve plate, described sieve plate is provided with a plurality of sieve screen apertures, it is characterized in that: on the described sieve plate array be provided with many V-type conical surfaces, the edge of described sieve screen apertures is the intersection cambered surface, described intersection cambered surface is located on the V-type conical surface.
