Description

Crushing type coal-gangue separation equipment

Technical field

A kind of crushing type coal-gangue separation equipment is the utility model is related to, belongs to coal field.

Background technology

Traditional bastard coal method for separating master has played sorting and wet cleaning method.Sorting is manually visually observed from motion Coal Cao finds out spoil, and the personnel that need to be played are more, and labor intensity is big, it is close with spoil color in coal and folder mud band sand when easily go out Situations such as now leakage is selected, falsely dropped, operating efficiency is low.Wet cleaning method is to realize to divide in liquid medium Cao with spoil proportion difference using coal Choosing, its required production cycle is long, equipment is expensive, complex process, and can cause water resource waste and pollution.

The content of the invention

The present invention provides a kind of crushing type coal-gangue separation equipment, solves the separation problem of coal and gangue in coal.

To achieve the above object, the technical solution adopted in the utility model is：

Crushing type coal-gangue separation equipment, it is characterized in that, including surface is provided with the roller of filter screen, the outer peripheral face of roller sets covering The firmly collecting box of drum strainer structure, the bottom of collecting box is funnel-form coal cinder collection port, and the inside of roller sets flight, spiral Drum inside is fixed in the outward flange of piece, and the middle part of flight is hollow out, and hollow out sets crushing shaft in the middle part of flight, and the one of crushing shaft Set hammer week, flight adjacent bit installs riser, and flight is fixed at riser both ends, and the height of riser is less than flight Width.

Preferably, the both ends of the roller are provided with external toothing, external toothing is provided with the support gear of multigroup engagement, supports tooth Wheel is driven by motor.

Further preferred, the feed end of the roller is provided with feed chute, and feed chute bottom is engraved in the middle part of flight Empty position gos deep into inside flight, and the discharge end of roller sets spoil collection port, and the lower passage of collection port sets multigroup be arranged in parallel Buffer bar, collection port lower passage outlet sets conveyer belt.

A step is preferred from now on, and the spoil collection port sets be vertically arranged shelter from roller discharge end middle and lower part outer ring Baffle plate, the crushing shaft is connected to crushing motor in roller discharge end through baffle plate.

The utility model has the advantage of：Underground bastard coal separation production process Cao is severe by condition of work, and space is small, behaviour It is inconvenient to make, and easily induces the production accident such as coal dust and gas explosion so that the broken choosing machinery of in general is difficult to select suitable underground The broken of gangue is integrated, is not required to additionally assemble screening mechanism, this equipment body by implement, this equipment with screening operation Product greatly reduces compared to original crushing and screening separate design, is easy to the disengaging mine of equipment；Internal structure is simple, and auxiliary is set Standby few, underground removes and installs facility, is easy to detection and maintenance, and environmental suitability is strong；Realize that crushing function works by jump bit Reliability is big, and multiple crush can improve breaking capacity, reduce plant capacity, reduce production cost.

Reference：

The external toothing 9 of 1 roller, 2 collecting box, 3 collection port, 4 flight, 5 crushing shaft, 6 hammer, 7 riser 8 supports the motor 11 of gear 10 The baffle plate 16 of 14 conveyer belt of feed chute 12 gangue collection port, 13 buffer bar 15 crushes motor.

Embodiment

The utility model is a kind of by raw coal is broken and coal and the equipment of gangue separation, and this equipment is by the broken of gangue It is broken to be integrated with screening operation, it is not required to additionally assemble screening mechanism, this equipment volume is set compared to original crushing and screening separation Meter greatly reduces, and is easy to the disengaging mine of equipment.

Structure of the present utility model, a kind of crushing type coal-gangue separation equipment, it is characterized in that, including surface be provided with filter screen rolling Cylinder 1, the outer peripheral face of roller 1 set the collecting box 2 for covering the filter structure of roller 1, and the bottom of collecting box 2 is collected for funnel-form coal cinder Mouth 3, the inside of roller 1 set flight 4, and the inner side of roller 1 is fixed in the outward flange of flight 4, and the middle part of flight 4 is hollow out, The middle part hollow out of flight 4 sets crushing shaft 5, and crushing shaft 5 sets hammer 6 for one week, and the adjacent bit of flight 4 installs riser 7, riser Flight 4 is fixed at 7 both ends, and the height of riser 7 is less than the width of flight 4.

The both ends of roller 1 are provided with external toothing 8, and external toothing 8 is provided with the support gear 9 of multigroup engagement, and support gear 9 is by motor 10 drivings.

The feed end of roller 1 is provided with feed chute 11, and spiral shell is goed deep into the bottom of feed chute 11 from the middle part hollow out position of flight 4 Inside blade 4, the discharge end of roller 1 sets spoil collection port 12, and the lower passage of collection port 3 sets multigroup buffer bar be arrangeding in parallel 13, the lower passage outlet of collection port 3 sets conveyer belt 14.

Spoil collection port 12 sets the baffle plate 15 for sheltering from the discharge end middle and lower part outer ring of roller 1 being vertically arranged, the powder Broken axle 5 is connected to through baffle plate 15 in the discharge end of roller 1 and crushes motor 16.

Rolling letter 1 and crushing shaft 5 drive by outside fire-proof motor to be rotated, roll simple 1 surface uniformly dispersing sieve aperture so that by Broken coal grain is sifted out, and gangue is admitted to the simple Cao of rolling from feed chute 11, and transmission is carried forward under the promotion of flight 4, The elevated lifting of plate 7 is reversely rotated with rolling letter 1 to rolling letter top and free-falling, hammer 6 and produced using rotation at a high speed afterwards Impulsive force to being crushed to the gangue by falling, the relatively low coal cinder of hardness falls on the simple bottom of rolling after being broken, through rolling letter On sieve aperture discharge, and leftover materials then from flight continue to driving front carry out next round impact grinding, so through excessively take turns The impact of hammer, coal grain is sifted out by the sieve aperture in rolling letter, and bulk gangue is then discharged by discharging opening, falls into spoil collection port 12.Riser occurs in pairs with hammer, can be designed to 2 pairs or 3 pairs according to need to actually play.Slowly operating transmits material for rolling letter And hammer runs at high speed the material that is slided from riser of impact in the opposite direction, tune can be passed through for the coal cinder of different hardness The rotating speed for saving hammer adjusts impact dynamics to meet that different broken play is asked.A diameter of 50 mm of sieve aperture or so, such 1 seat The equal ＜ 50mm of coal grain diameter gone out.

The broken of gangue is integrated by this equipment with screening operation, is not required to additionally assemble screening mechanism, this equipment body Product greatly reduces compared to original crushing and screening separate design, is easy to the disengaging mine of equipment；Internal structure is simple, and auxiliary is set Standby few, underground removes and installs facility, is easy to detection and maintenance, and environmental suitability is strong；Realize that crushing function works by jump bit Reliability is big, and multiple crush can improve breaking capacity, reduce plant capacity, reduce production cost.
