Description

A kind of coal washery is used for the raw coal vibrating screen of media coal separation

Technical field

The utility model belongs to colliery manufacture field, more specifically, the utility model is related to a kind of coal washery and is used to be situated between The raw coal vibrating screen of matter coal separation.

Background technology

Coal washery uses media coal separation mostly at present, is directly over belt from ground production system coal is transported to vibrating screen to fall Coal point, conveyer belt is unloaded coal a little has 2.6 meters of height to coal dropping point, and the direct flushing vibration sieve of coal stream, it is vibrating screen that vibrating screen, which connects coal point, Sieve, easily causes the damage of vibrating screen mesh；If inspection is not in place, there is more damage in sieve, causes Coal Quality Decline, shadow Ring coal quality；It is laid with using the sieve plate of damage is double-deck, and the loss of coal can be caused, and while filter screen is replaced, is existed Some potential safety problems.

Utility model content

Technical problem to be solved in the utility model is to provide that a kind of coal washery is easily changeable, original for media coal separation Coal vibrating screen.

To achieve these goals, the technical solution that the utility model is taken is：A kind of coal washery is used for media coal separation Raw coal vibrating screen, including filtering screen frames, the filtering screen frames include filter screen, the filter screen and surface water horizontal line Sieves base of frame is located in the first inclined at acute angles, top is equipped with surface water horizontal line in the second inclined at acute angles at the top of filter screen Filter plate, the filter surface are equipped with multiple equally distributed through holes, and second acute angle is more than the inclination angle of the first acute angle Degree, filter plate are located at the correspondence position of raw coal release position.

A kind of coal washery disclosed in the utility model is used for the raw coal vibrating screen of media coal separation, and the filtering screen frames include Crossbeam, the crossbeam are located at the backboard front of filtering screen frames, and filter plate top fold is equipped with fixed plate, and the fixed plate passes through Fixing screws are fixed in the backboard of filtering screen frames.

A kind of coal washery disclosed in the utility model is used for the raw coal vibrating screen of media coal separation, and first acute angle is 30 ° ~50 °, second acute angle is 55 °~75 °.

A kind of coal washery disclosed in the utility model is used for the raw coal vibrating screen of media coal separation, the sieves base of frame Equipped with roller, the roller is symmetrically arranged at the both sides of sieves base of frame, and the roller of both sides is connected by wheel shaft, the roller bearing Rolling is connected to sieves base of frame.

Using the technical program, part stainless steel mesh is replaced with wear-resisting filter plate with holes is made by oneself, with raw coal sieve crossbeam into Row is fixed, and raw coal vibrating screen is directly washed away for coal during buffer conveyor coal breakage, extends the service life of filter screen, passes through To the Optimal improvements of filter screen, the direct impact force of the anti-coal stream of sieve is strengthened, while expands the area of coal dropping point, Impact force when disperseing to connect coal, reduces the damaged condition of filter screen to greatest extent, extends the service life of filter screen, no Master Cost has only been saved, while has improved coal quality, has added benefit, has reduced the security threat for frequently replacing screen belt, It ensure that the safety in production of coal washery.

Below with reference to drawings and examples, the utility model is described in detail.

Brief description of the drawings

The content expressed by each width attached drawing of this specification and the mark in figure are briefly described below：

Fig. 1 is the schematic diagram for the raw coal vibrating screen that a kind of coal washery of the utility model is used for media coal separation；
