Abstract

The utility model discloses a multi-layer vibrating screen mesh, comprising a first screen plate, a second screen plate and a third screen plate which are placed in an overlapped way, the surface of each screen plate is provided with screen holes, the hole diameters of the screen holes in the surface of each screen plate are gradually reduced from one end of the screen plate to the other end of the screen plate, and the hole diameters of the screen holes at the corresponding positions of the first screen plate, the second screen plate and the third screen plate are gradually reduced from top to bottom. The multi-layer vibrating screen mesh disclosed by the utility model has the advantages of being simple in structure, obvious in screening effect and convenient to clean, reducing the production cost while prolonging the service life and improving the screening efficiency.

Description

The multilayer vibration screen

Technical field

The utility model relates to the vibration screening machinery field, relates in particular to a kind of multilayer vibration screen of simple and durable.

Background technology

Mineral grain classification generally finished by vibratory sieve.

Because the number of plies of the screen cloth that adopts of vibratory sieve is relevant with the granularity requirements of stock grading, so how much a stage material of the routine maximum of accounting had a direct relation during the disposal ability of vibratory sieve was formed with material.Thicker material moves at screen cloth, has directly influenced vibratory sieve volume disposal ability and screening efficiency, therefore, needs to adopt the multilayer screen cloth to come the layering screening.

Summary of the invention

The purpose of this utility model is to provide the multilayer vibration screen that a kind of screening effect is obvious, be convenient to clear up, improve screening efficiency.

To achieve these goals, the multilayer vibration screen that the utility model provides comprises: first sieve plate of overlapped placement, second sieve plate and the 3rd sieve plate, every sieve plate surface is distributed with sieve aperture, the pore size of every sieve plate surface sieve aperture dwindles gradually from an end to the other end of sieve plate, and the screen-aperture of first sieve plate, second sieve plate and the 3rd sieve plate corresponding position dwindles from top to bottom gradually.

In some embodiments, sieve aperture is that circular, rhombus or other are irregularly shaped.

Multilayer vibration screen of the present utility model, simple in structure, screening effect obviously, be convenient to cleaning, when improving its practical life-span, reduced production cost, improved screening efficiency.

Description of drawings

Fig. 1 is the structural representation of the multilayer vibration screen of a kind of embodiment of the utility model;

Fig. 2 is the structural representation of first sieve plate in this multilayer vibration screen shown in Figure 1.

The specific embodiment

Come the utility model is described in further detail explanation below in conjunction with drawings and the specific embodiments.

Fig. 1 and Fig. 2 have schematically shown the multilayer vibration screen according to a kind of embodiment of the utility model.As shown in the figure, multilayer vibration screen of the present utility model comprises: first sieve plate 10 of overlapped placement, second sieve plate 20 and the 3rd sieve plate 30, the first sieve plates 10, second sieve plate 20 and the 3rd sieve plate 30 adopt steel plate to make.

First sieve plate 10, second sieve plate 20 and the 3rd sieve plate 30 surfaces are distributed with first sieve aperture 101, second sieve aperture and the 3rd sieve aperture respectively.First sieve aperture 101, second sieve aperture and the 3rd sieve aperture can be various geometries such as circle, ellipse, polygon, the sieve aperture shape of same sieve plate is identical, in this embodiment of the utility model, first sieve aperture 101, second sieve aperture and the 3rd sieve aperture are circle.

As shown in the figure, the pore size of every sieve plate surface sieve aperture dwindles gradually from an end to the other end of sieve plate, and the screen-aperture of first sieve plate 10, second sieve plate 20 and the 3rd sieve plate 30 corresponding positions dwindles from top to bottom gradually.

Claims

1. multilayer vibration screen, it is characterized in that, comprise: first sieve plate (10) of overlapped placement, second sieve plate (20) and the 3rd sieve plate (30), every sieve plate surface is distributed with sieve aperture, the pore size of every sieve plate surface sieve aperture dwindles gradually from an end to the other end of sieve plate, and the screen-aperture of described first sieve plate (10), second sieve plate (20) and the 3rd sieve plate (30) corresponding position dwindles from top to bottom gradually.

2. multilayer vibration screen according to claim 1 is characterized in that, described sieve aperture is that circular, rhombus or other are irregularly shaped.
