Abstract

The utility model provides a sieve plate with an anti-break function, which is composed of transverse and vertical sieve bars, an anti-break plate, an anti-break beam and a sieve frame, wherein, the transverse and the vertical sieve bars are welded vertically into a rectangle sieve plate and fixed on the sieve frame together with the anti-break beam, and the anti-break beam is arranged below the sieve plate. Because the existence of the anti-break beam, the vibration on the sieve bars can be buffered, and the breaking of sieve bars due to long-time vibration can be prevented. Consequently, the service life of the sieve plate can be increased by 3-5 times, and the machine stop and the production stop which are caused by maintenance can be reduced. Thereby, the utility model has the advantages of easy installation, long service life, high production efficiency and maintenance cost decrease.

Description

Sieve plate with anti-break function

The utility model relates to the wash coaling equipment in a kind of colliery, especially a kind of anti-disconnected wedge wire screen plate on the reciprocating sieve.

The wedge wire screen plate that uses on the reciprocating sieve is to be welded by horizontal grating and perpendicular grating at present, and in use, sieve plate is owing to being in vibrating state for a long time, so horizontal grating is easy to fracture in the centre and scrap.

The purpose of this utility model provides a kind of wedge wire screen plate that prevents that horizontal grating from fractureing.

The purpose of this utility model realizes in the following manner, i.e. anti-disconnected plate of welding in the middle of every horizontal grating, and the anti-disconnected plate of each piece all is pressed on the anti-disconnected beam reaches with these vibrations that alleviate horizontal grating and to prevent the purpose that fractures.

Figure of description 1 is a sieve plate sectional view of the present utility model;

Figure of description 2 is a sieve plate cross-sectional view of the present utility model;

Figure of description 3 is a sieve plate bottom view of the present utility model.

With reference to Figure of description sieve plate of the present utility model is explained;

Anti-disconnected its parts of wedge wire screen plate of the present utility model comprise horizontal grating (2), perpendicular grating (1), the anti-plate (3) that breaks, anti-disconnected beam and screen frame (unit) (4) etc., and perpendicular grating (1) forms the rectangle sieve plate with anti-disconnected with the mutual vertical welding of horizontal grating (2) together Beam together is fixed on the screen frame (unit) (4), and anti-disconnected beam is positioned at the below of sieve plate.

All level is welded with an anti-disconnected plate (3) in the centre of every horizontal grating (2), and its plane and the anti-beam that breaks contact.Anti-disconnected beam is made up of steel plate bar (5) and rubber strip (6), and steel plate bar embedding (5) is among rubber strip (6), and the two ends solid welding of steel plate bar (5) is on screen frame (unit) (4).

Embodiment:

Anti-disconnected wedge wire screen plate system bar of the present utility model is very easy to the anti-disconnected plate of promptly burn-oning in the middle of horizontal grating, installing anti-disconnected beam below the sieve plate and allowing rubber strip withstand on the plane of each anti-disconnected plate, most of weight owing to sieve plate during use all is pressed on the anti-disconnected beam, under the cushioning effect of rubber strip, eliminate the vibrations of horizontal sieve plate, prolong the service life of sieve plate so can prevent the fracture of the horizontal grating of sieve plate effectively.

By using proof, anti-disconnected wedge wire screen plate of the present utility model is compared its life-span and is improved 3～5 times with original sieve plate, and can greatly reduce the stopping production that causes because of maintenance, and therefore having raising output easy to use, characteristics such as the long service life that reduces production costs have good use value.

Claims
