Abstract
The dry coal separator as one medium-free coal separator includes raw coal bin, raw coal belt conveyor, raw coal chute, coal hopper, lump coal chute, coal gangue belt conveyor, upper and lower chutes, belt conveyor, crusher and refined coal belt conveyor. It includes also vibration sieve and the raw coal belt conveyor is installed in front of the vibration sieve with the coal outlet over the vibration sieve being connected to the vibration sieve through the raw coal chute. The present invention has the advantages of saving water, simple equipment and low coal separating cost.
Description
The present invention relates to a kind of dry coal separator, it belongs to a kind of no medium cleaning unit.
Owing to contain a large amount of impurity and ashes in the raw coal, thereby had a strong impact on the use value of raw coal.For improving the quality of raw coal, people adopt now has the cleaning unit of medium that raw coal is carried out washing.Owing to have the medium cleaning unit to carry out washing to raw coal, so this equipment exists shortcomings such as waste water resource, equipment complexity, coal washing cost height with a large amount of water.
The purpose of this invention is to provide a kind of simple and low dry coal separator of coal separation cost of water resource, device structure of saving.
Task of the present invention is achieved in that this dry coal separator comprises run coal bin, the raw coal belt conveyor, the raw coal chute, connect coal bunker, the lump coal chute, low speed dirt extraction belt conveyor, last chute, following chute, belt conveyor, pulverizer and cleaned coal belt conveyor, wherein it also comprises the mesh reciprocating sieve, the raw coal belt conveyor is contained in the front of mesh reciprocating sieve, its coal exit is located at the top of mesh reciprocating sieve and links to each other with the mesh reciprocating sieve by the raw coal chute, connect the below that coal bunker is located at the mesh reciprocating sieve, low speed dirt extraction belt conveyor is located at the back of mesh reciprocating sieve, its coal-feeding end is located at the below of mesh reciprocating sieve sieve plate and links to each other with the mesh reciprocating sieve by the lump coal chute, belt conveyor is located at the below of low speed dirt extraction belt conveyor, its coal-feeding end be located at connect coal bunker below, the coal exit of low speed dirt extraction belt conveyor and belt conveyor all is located at the top of pulverizer and links to each other with pulverizer with following chute by last chute, and the cleaned coal belt conveyor is located at the below of pulverizer.
The mesh aperture of above-mentioned mesh reciprocating sieve is the 10-30 millimeter.
Above-mentioned mesh reciprocating sieve can also replace with rotary screen.
Because the present invention has adopted technique scheme, therefore compare with background technology, have following advantage:
1, save water resource: the aqueous medium coal separation needs a large amount of waters, and one ton of cleaned coal of every production needs 0.5 ton of water consumption, and therefore coal separation of the present invention water not can save water resource;
2, equipment is simple: the present invention adds a mesh reciprocating sieve by four belt conveyors to constitute, and it is simple in structure, easy to use;
3, the coal separation cost is low: because the present invention can the near coal-mine coal separation in the colliery, both can save near coal-mine freight charges to coal preparation plant, therefore the coal slime loss of anhydrous medium coal separation again can improve the utilization rate of coal resources, has reduced the coal separation cost.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, it comprises run coal bin 1 dry coal separator among this embodiment, raw coal belt conveyor 2, raw coal chute 3, connect coal bunker 5, lump coal chute 6, low speed dirt extraction belt conveyor 7, last chute 9, following chute 10, belt conveyor 8, pulverizer 11 and cleaned coal belt conveyor 12, wherein it comprises that also being provided with the mesh aperture is 15 millimeters mesh reciprocating sieve 4, raw coal belt conveyor 2 is contained in the front of mesh reciprocating sieve 4, its coal exit is located at the top of mesh reciprocating sieve 4 and links to each other with mesh reciprocating sieve 4 by raw coal chute 3, and the coal-feeding end of raw coal belt conveyor 2 is located at the below of run coal bin 1; Connect the below that coal bunker 5 is located at mesh reciprocating sieve 4, the cleaned coal that collection screen is good; Low speed dirt extraction belt conveyor 7 is located at the back of mesh reciprocating sieve 4, and its coal-feeding end is located at the below of mesh reciprocating sieve 4 sieve plates and links to each other with mesh reciprocating sieve 4 by lump coal chute 6; Belt conveyor 8 is located at the below of low speed dirt extraction belt conveyor 7, its coal-feeding end be located at connect coal bunker 5 below, the coal exit of low speed dirt extraction belt conveyor 7 and belt conveyor 8 all is located at the top of pulverizer 11 and links to each other with pulverizer 11 with following chute 10 by last chute 9, cleaned coal belt conveyor 12 is located at the below of pulverizer 11, and the cleaned coal of choosing is delivered in the cleaned coal storehouse.
The mesh aperture of above-mentioned mesh reciprocating sieve 4 can also be selected in the scope according to the 10-30 millimeter that do not coexist that contains spoil in the coal.
Above-mentioned mesh reciprocating sieve 4 can also replace with rotary screen.
Operation principle of the present invention is: when the raw coal of exploiting out after run coal bin, raw coal belt conveyor are delivered to the mesh reciprocating sieve, the mesh reciprocating sieve will be sent in the low speed dirt extraction belt conveyer greater than the lump coal and the spoil in mesh aperture, in the running of low speed dirt extraction belt conveyor, manually spoil is sent, reach the purpose that the spoil in the raw coal, pyrites are removed, come out to enter the pulverizer and pulverize after the cleaned coal belt conveyor is sent in the cleaned coal storehouse from connecing coal bunker with lump coal through belt conveyor less than the raw coal in mesh aperture.
