Description
Technical field
The utility model relates to mine bastard coal separation equipment, is particularly useful for the direct sorting of down-hole, mine coarse coal and gangue.
Background technology
The separation of bastard coal all is to carry out on ground at present, and the sorting mode has picking, wet concentration, selection by winnowing, gamma ray sorting.Picking: be soon, from ribbon conveyer mixing coal, pick the bulk spoil with hand by artificial usefulness.Its condition of work is very arduous, efficient is low, easily causes and falsely drops, leaks choosing, and potential safety hazard is big.Wet concentration: be to utilize coal different with the proportion of spoil, separate coal and spoil by buoyancy of water, separating effect is better.But its apparatus expensive, complex process, required place is big, uses difficulty in the down-hole.Selection by winnowing: utilize coal different, produce coal and spoil, be applicable to the area of water resource poorness by the buoyancy separation of wind with the density of spoil.Its investment is big, floor space greatly outside, dust-reclamiing mill is bigger, treatment effect is undesirable, the incompatibility subsurface environment.Gamma ray bastard coal sorting: be to adopt gamma ray identification coal and spoil, produce the different signals of telecommunication according to gamma ray in that coal is different with attenuation in the spoil, by the FEEDBACK CONTROL executing agency of the signal of telecommunication, executing agency changes the movement locus of spoil, thereby reaches the purpose that bastard coal separates.But its system complex, sorting capability is little, and the radiation hidden danger of radioactive source often has water or coal slime in the on-the-spot raw coal, and coal cinder, spoil surface are covered by coal slime, causes the difficulty in the identification.Along with the raising day by day of mining mechanization degree, sneaking into bulk spoil amount in the coal increases gradually, in aboveground sorting, causes environmental pollution, takies the farmland.As be used in the backfill in goaf, and will mix coal and transport to ground by the down-hole, the spoil that sub-elects is transported the down-hole back from ground again, and both wastes of manpower are uneconomical again, cause secondary pollution.Therefore, how the direct sorting of carrying out bastard coal in the down-hole is the problem that current urgent need solves.
The utility model content
The purpose of this utility model is according to the problem that exists in the prior art, and a kind of compact conformation is provided, and size is little, easy accessibility, the mine bastard coal separation equipment that directly carries out the sorting of bulk bastard coal in the down-hole.
Mine bastard coal separation equipment of the present utility model, it is combined by screening crusher, forward type belt conveyer, screening machine, the breaking seperator of selection and rear-mounted belt conveyer; Wherein: the forward type belt conveyer is obliquely installed, and its low side links to each other with screening crusher, and high-end the inlet with screening machine joined; Rear-mounted belt conveyer continues below forward type belt conveyer high-end; Select breaking seperator to be located at the afterbody of screening machine, select the afterbody of breaking seperator to be provided with the spoil transporter; Screening machine, the breaking seperator of selection and spoil transporter ride over the top of rear-mounted belt conveyer; All motor all adopt fire-proof motor.
Height h≤the 3.8m of described screening machine; The breaking seperator of described selection is located at the impeller that knocks bastard coal of spiral sieve plate top by the spiral sieve plate, and the axle and the shaft coupling of impeller rotation constitute.
Mine bastard coal separation equipment of the present utility model, condition and situation according to the down-hole, mine, a plurality of equipment are organically combined, by the breaking seperator of custom-designed selection, the bulk bastard coal is directly carried out separating of coal and gangue in the down-hole, make the bulk spoil not go out well, can be directly used in the filling in goaf.Not only solved a large amount of transportation problem, saved ground and piled up floor space, avoid expenses such as surface subsidence, environmental improvement, the backfill for the down-hole simultaneously provides a large amount of raw materials.Can reduce freight, ground piles up floor space, avoids surface subsidence, reduces the pollution of environment, expenses such as environmental improvement, save the down-hole of spoil, aboveground freight volume, this method is skillfully constructed, its facility compact, size is little, easy accessibility, good separating effect has practicality widely in this area.

Fig. 2 is the vertical view of Fig. 1.
Among the figure: the 1-screening crusher, 2-forward type belt conveyer, 3-screening machine, 4-are selected breaking seperator, the rear-mounted belt conveyer of 5-, 6-spoil transporter.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Mine bastard coal separation equipment shown in Figure 1, constitute by screening crusher 1, forward type belt conveyer 2, screening machine 3, the breaking seperator 4 of selection, rear-mounted belt conveyer 5 and spoil transporter 6, all motor all adopt fire-proof motor, forward type belt conveyer 2 is obliquely installed, low side is connected with screening crusher 1, the rear-mounted belt conveyer 5 of high-end below continued access, screening machine 3 is located on the rear-mounted belt conveyer 5, its screen box is connected on the end opening place of forward type belt conveyer 2, the height h≤3.8m of screening machine 3.Screening machine 3 rear portions are provided with selects breaking seperator 4, select breaking seperator 4 to have spoil transporter 6, select breaking seperator 4 by the spiral sieve plate, knock a plurality of impellers of coal and gangue, the axle and the shaft coupling of impeller rotation constitute, a plurality of impellers are arranged side by side, select the motor front end of breaking seperator 4 that the frequency converter of controlling its rotating speed is housed, drive the driving shaft rotation by shaft coupling, driving shaft connects the impeller rotation by key, when the bastard coal mixture enters when selecting breaking seperator 4 by the baffle plate that is located at its both sides, impacted 2 to 4 times by the impeller of its rotation, coal is broken into pieces, and the spoil that is not crashed to pieces flows to the rear end and enters spoil transporter 6.
The course of work: coal that underground mining is come out and gangue mixed material are sent into screening crusher 1 and are carried out preliminary fragmentation, by forward type belt conveyer 2 material is sent into screening machine 3 then and carry out material screening, fall into through the mixing coal less than 50mm of screening machine 3 screening and enter rear-mounted belt conveyor 5 under the sieve and send into the down-hole coal bunker; Then enter in the breaking seperator 4 of selection greater than 50mm mixing coal, rotary blade in selecting breaking seperator 4 knocks bulk mixing coal is carried out cracking and sorting, broken coal less than 50mm, fall into rear-mounted belt conveyor 5 by the spiral sieve plate of selecting breaking seperator 4 and send into the down-hole coal bunker, the spoil of not broken into pieces gets rid of to backboard under the active force of middle impeller helical rotation, and falling into spoil transporter 6, to send into waste bin standby.
