Abstract
A separating machine for selective crushing and separating of coal and gangue comprises: a spiral screen plate formed by combining a plurality of screw rod assemblies disposed on one end of an underframe; gears in mutual transmission which are arranged between a plurality of screw rod assemblies. A power installation for rotating the plurality of screw rod is connected with the spiral screen plate by a coupler. A plurality of impact impellers fixed on a transmission shaft along the direction of the screw rod is provided above the spiral screen plate. The transmission shaft of each impact impeller is supported in a bearing seat of a housing and connected with an explosion proof motor disposed on the other end of the underframe by the coupler. The separating machine can separate the coal and the gangue underground, make bulk gangue directly fill a gob area without being discharged from mine, which not only save the costs for transport, ground land occupation, preventing surface subsidence, environmental treatment and the like, but also can reduce environmental pollution and save transport capacity of the gangue both in surface and underground. The invention has advantages of simple and compact equipment, convenience for assembling and disassembling, good separation effect, and extensive practicality.
Description
Technical field
The present invention relates to select crushing type gangue separator, be particularly useful for the sorting of down-hole, mine coarse coal and gangue.
Background technology
Coal separates with gangue, and common method for separating has artificial hand selection, wet concentration, selection by winnowing, gamma ray sorting.
1) artificial hand selection: mainly be that personnel selection is watched, from ribbon conveyer mixing coal, pick the bulk spoil with hand.Its condition of work is very arduous, efficient is low, easily causes and falsely drops, leaks choosing, and potential safety hazard is big.
2) wet concentration: utilize coal different with the proportion of gangue, separate coal and spoil by buoyancy of water, separating effect is better.But its apparatus expensive, complex process, required place is big, and a large amount of water are deposited nowhere in the down-hole.Therefore use difficulty in the down-hole.
3) 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.
4) gamma ray bastard coal separator: 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, FEEDBACK CONTROL executing agency by the signal of telecommunication, executing agency changes the movement locus of spoil, thereby reaches the purpose that bastard coal separates.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, and above-mentioned several coal preparation methods all are to carry out on ground, its equipment overall structure complexity, floor space is big, involves great expense, and is difficult in maintenance, contaminated environment, the cost height is not suitable for the down-hole.
Summary of the invention
According to the problem that exists in the prior art, the purpose of this invention is to provide a kind of simple in structurely, volume is little, and easy accessibility is applicable to the selection crushing type gangue separator of down-hole.
Selection crushing type gangue separator of the present invention, be provided with the spiral sieve plate that is arranged in a combination by many screw rods at underframe one end, be provided with the gear of mutual transmission between the screw rod of many permutation and combination, the spiral sieve plate is connected with the power set that many screw rods are rotated by shaft coupling; Spiral sieve plate top is provided with a plurality of impact impellers that are fixed on power transmission shaft on consistent with the screw rod direction, and the cardan-shaft suspension that impacts impeller is in the bearing block of housing, and this power transmission shaft is connected with the flame-proof electric motor that is located at the underframe other end by shaft coupling.
The power set of described spiral sieve plate are made of with the decelerator that links to each other by shaft coupling flame-proof electric motor; Blade on the described impact impeller is provided with a plurality of teeth along direction of rotation one side, and its blade can be 2～4.
The bastard coal underground separation is an indispensable link in the Coal Production process, particularly emphasizes to carry out green environment production at present, realizes that it is particularly important that this production link seems under the prerequisite of sustainable development.Selection crushing type gangue separator of the present invention, to directly carry out separating of coal and gangue greater than the bulk bastard coal of 50mm in the down-hole, make the bulk spoil not go out well, can be directly used in the filling in goaf, not only reduce freight, saving ground land seizure, prevent expenses such as surface subsidence, saving environmental improvement, minimizing is to the pollution of environment, and save under the waste shaft, aboveground freight volume.Its equipment is simple, compact, and size is little, easy accessibility, and good separating effect has practicality widely in the present technique field.

Fig. 1 is a structural front view of the present invention.
Fig. 2 is a structure side view of the present invention.
Fig. 3 is a structure vertical view of the present invention.
Among the figure: the 1-underframe, the 2-housing, 3-spiral sieve plate, 4-impacts impeller, and 5,8, the 10-shaft coupling, 6, the 7-flame-proof electric motor, the 9-decelerator.
The specific embodiment
The invention will be further described below in conjunction with the embodiment in the accompanying drawing:
Selection crushing type gangue separator of the present invention mainly is made of with the impeller that is located at spiral sieve plate 3 tops the spiral sieve plate 3 that is located on the underframe 1.Spiral sieve plate 3 is arranged in a combination by many screw rods, be provided with the gear of mutual transmission between the screw rod of many permutation and combination, spiral sieve plate 3 is connected with the power set that many screw rods are rotated by shaft coupling 10, and power set are made of with the decelerator 9 that links to each other by shaft coupling 8 flame-proof electric motor 7.Spiral sieve plate 3 is slowed down by decelerator 9 by flame-proof electric motor 7, drives spiral sieve plate central screw shaft and rotates, and central screw shaft connects the screw rod rotation of gear driven both sides by key, thereby realizes screening and conveying.Spiral sieve plate 3 tops are provided with a plurality of impact impellers 4 that are fixed on power transmission shaft on consistent with the screw rod direction, and the blade that impacts on the impeller 4 is provided with a plurality of teeth along direction of rotation one side, and its blade can be 2～4.The cardan-shaft suspension that impacts impeller 4 is in the bearing block of housing 2, and this power transmission shaft is connected with the flame-proof electric motor 6 that is located at underframe 1 other end by shaft coupling 5.Motor 6 rotates by the impact impeller 4 that shaft coupling 5 drives on the driving shaft, when the bastard coal mixed material enters seperator, the impact impeller 4 that is configured rotating speed in advance impacts 2～4 times, coal is broken and spoil is not broken, when the bastard coal that impacted dropped on the spiral sieve plate 3, by the 3 rotation screenings of spiral sieve plate, the broken fritter coal cinder of crossing fell into sieve down, the bulk spoil that is not broken is stayed on the compass screen surface, is transported to discharging opening by rotary screw.
