Abstract

The utility model relates to an improvement of the structure of a sieving machine. The utility model comprises a shell. The shell is provided with an upper feeding mouth, a lateral outlet and a bottom outlet. The key point of the structure is that a roller grizzly, which is composed of a driving chain wheel, a driven chain wheel and a chain, is arranged inside the shell. The shaft of the driving chain wheel is connected with a motor by means of a belt pulley. The shaft of the chain is provided with a screen. The outer side of the shell is provided with a transverse vibrating motor. The utility model has characteristics of good sieving effect and simple structure.

Description

The whirling vibration sieve

The utility model relates to the improvement of screening machine structure.

At used screening machines of industry such as metallurgy, chemical industry, electric power, coal, building materials, its screen cloth mostly is oblique and fixedly installs at present, and screen cloth carries out the screening of material with vertical vibration, its shortcoming is that screen cloth easily stops up, therefore, screening effect is unsatisfactory, and easily produces the heap of material on screen cloth.

The purpose of this utility model just provides a kind of whirling vibration sieve with fine screening effect.

The purpose of this utility model is achieved in that the utility model comprises housing, have top charging aperture, side outlet, outlet at bottom on the housing, its structural feature is to be provided with the drum screen that is made of drive sprocket, driven sprocket, chain in housing, the axle of drive sprocket links to each other with motor by belt pulley, and the axle of chain is provided with screen cloth; The arranged outside of housing has the oscillation crosswise motor.

Major advantage of the present utility model:

1, screening effect is good:

Because the axle of the utility model chain is provided with screen cloth, just makes material not stop to screen in the rotary course at screen cloth; And screen cloth can be around the axle turnover panel, and promptly screen cloth does not stop to obtain cleaning, and screen cloth just is difficult for stopping up, and therefore just can improve screening effect greatly, the also more difficult phenomenon that produces the heap material on screen cloth;

2, simple in structure:

The utility model main member be chain and on screen cloth, motor, its member is simple, be easy to make, and is easy to popularize.

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

Fig. 2 is A-A cutaway view of Fig. 1;

Fig. 3 is the I place enlarged drawing of Fig. 1.

Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:

The utility model comprises housing 1, have top charging aperture 8, side outlet 12, outlet at bottom 2 on the housing 1, be provided with the drum screen 3 that constitutes by drive sprocket 4, driven sprocket 11, chain 7 in the housing 1, the axle 5 of drive sprocket 4 links to each other with motor 14 by belt pulley 13, and the axle 10 of chain 7 is provided with screen cloth 9; The arranged outside of housing 1 has oscillation crosswise motor 15.

In order further to improve the effect of cleaning screen cloth 9, brush roll 6 can be set in the side of drive sprocket 4.

Two cover drum screens 3 up and down also can be set, to adapt to the needs of different user.

Narrate a course of action of the present utility model below:

Material enters drum screen 3 by top charging aperture 8, after screen cloth 9 (oscillation crosswise motor 15 vibrates simultaneously) screening, enters into outlet at bottom 2, and the material that is not fallen by sieve does not then move on, discharges along side outlet 12; When material is discharged from side outlet 12, screen cloth 9 is rolling downwards with driven sprocket 11, and 9 of screen clothes rotate around axle 10, in vertical state, screen cloth 9 (oscillation crosswise motor 15 vibrates it simultaneously) is gone up residual material and is freely fallen because of weight, and screen cloth obtains clearing up 9 this moments; When screen cloth 9 moves on, when walking around drive sprocket 4, brush roll 6 also can further be cleared up screen cloth 9.

Claims

1, the whirling vibration sieve comprises housing (1), have top charging aperture (8), side outlet (12), outlet at bottom (2) on the housing (1), it is characterized in that being provided with in the housing (1) drum screen (3) that constitutes by drive sprocket (4), driven sprocket (11), chain (7), the axle (5) of drive sprocket (4) links to each other by the same motor of belt pulley (13) (14), and the axle (10) of chain (7) is provided with screen cloth (9); The arranged outside of housing (1) has oscillation crosswise motor (15).

2, whirling vibration sieve according to claim 1 is characterized in that the outside of drive sprocket (4) is respectively arranged with brush roll (6).
