Description
Technical field
The present invention relates to a kind of bastard coal separation equipment, especially a kind of percussive bastard coal crushing and screening separation device that is applicable under the coal mine.
Background technology
The raising day by day of mining mechanization degree, along with the output increase of coal, the spoil amount of required separation also increases thereupon, owing to, easily cause environmental pollution in aboveground sorting, and the land occupation resource, increase cost.Begun at present to adopt in the down-hole and carried out the bastard coal separation,, reduced and pollute to reduce cost; Common down-hole gangue separating method has: artificial separation, gamma ray sorting, the sorting of fluid pressure type bastard coal etc., wherein: artificial separation: 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.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, 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.Its system complex, sorting capability is little, and there is radiation hidden danger in 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.The late at night screening test machine of fluid pressure type coal: this testing machine crushing process is complicated, adopts hydraulic pressure as broken power source, though adjustable in pressure, complex structure, and need special queueing mechanism with coal and spoil piece block-by-block pressurization sorting, production capacity is little.
The bastard coal underground separation is an indispensable link in the Coal Production process, particularly emphasizes to carry out friendly environment production now, realizes that it is particularly important that this production link seems under the prerequisite of sustainable development.Separate spoil in the down-hole, to goaf filling can reduce freight, ground is piled up the soil and is accounted for expenses such as expense, surface subsidence, environmental improvement, reduces the pollution of environment, saves the down-hole of spoil, aboveground freight volume.But there is not comparatively suitable processing method at present both at home and abroad,
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of simple in structure, efficiency of separation height, the percussive bastard coal crushing and screening separation device of good separation effect.
Technical scheme: percussive bastard coal crushing and screening separation device of the present invention, comprise underframe, the drive unit of forming by motor and double output shaft gear-box that is provided with on the underframe, by the front and back running roller of drive unit transmission and the conveyer belt of hauling by the front and back running roller, be located at the feed well at conveyer belt rear portion, the speed of service of described conveyer belt is 6～15m/s, on conveyer belt, be provided with consistent with its traffic direction, the material pressing belt that velocity magnitude equates, the anterior discharging opening of conveyer belt is provided with a breaker outward, breaker and discharging opening are spaced a distance, and discharging opening is provided with the sieve plate that separates the bulk spoil with below between the breaker.
The crushing shell that the horizontal vertical pivot angle that described breaker is articulated as one by front and back two bracing frames with front and back two bracing frames is adjustable constitutes; Described breaker and discharging opening distance at interval is 1～2m; The horizontal vertical pivot angle of described crushing shell is 0～10 °.
Beneficial effect: the present invention adopts the mode that high-speed transfer raw coal and crushing shell clash into mutually to separate coal and spoil, is particularly useful for need not offering special underground chambers or tunnel in the narrow and small tunnel of down-hole.Its power of motor is selected 30kw for use, and the material size scope is 50～100mm; Discharging-material size: coal 0～50mm, spoil 50～100mm; Disposal ability is 300 tons/hour.Advantage is: the stroke speed of material can be adjusted, and obtaining different impulsive forces, the bastard coal of different hardness is separated.Because the effect of material pressing belt, can make material obtain the impact velocity of the highest 15m/s stably.Broken and screening function is integrated in one, and crushing shell is connected with the equal bolt of sieve plate, is fixed on the underframe, and it is convenient to change.Solved a large amount of transportation problem, saved a large amount of farmlands, the backfill for the down-hole simultaneously provides a large amount of raw materials.It is simple in structure, efficiency of separation height, and good separation effect has practicality widely.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A view among Fig. 1.
Among the figure: feed well-1, conveyer belt-2, material pressing belt-3, crushing shell-4, sieve plate-5, drive unit-6, underframe-7.
The specific embodiment
Below in conjunction with in the accompanying drawing one embodiment of the present of invention being further described:
Percussive bastard coal crushing and screening separation device of the present invention, by will be by feed well 1, conveyer belt 2, material pressing belt 3, breaker, sieve plate 5 and drive unit 6 constitute.Drive unit 6 is made up of motor and double output shaft gear-box, running roller before and after drive unit 6 transmissions, conveyer belt 2 by the haul of front and back running roller, the speed of service of conveyer belt 2 is 6～15m/s, be equipped with consistent on the conveyer belt 2 with its traffic direction, the material pressing belt 3 that velocity magnitude equates, the rear portion of conveyer belt 2 is provided with the feed well 1 that places in the protective cover, conveyer belt 2 anterior discharging openings are provided with a breaker outward, breaker is about 1～2m apart from the discharging opening position, the crushing shell 4 that the horizontal vertical pivot angle that breaker is articulated as one by front and back two bracing frames with front and back two bracing frames is adjustable constitutes, and the horizontal vertical pivot angle of crushing shell 4 is 0～10 °.Conveyer belt 2 is located on the underframe 7 with drive unit 6, and the discharging opening at conveyer belt 2 rear portions is provided with the sieve plate 5 that separates the bulk spoil with the below between the breaker.
During work, raw coal is slipped on the conveyer belt 2 that the speed of service is 6～15m/s by feed well 1, the speed of service is adjustable, conveyer belt 2 drives material and impacts preposition crushing shell 4 with high-speed straight-line, being provided with material pressing belt 3 above the conveyer belt of carrying at a high speed 2, is in order to prevent that material from beating or slide the drive unit drive that conveyer belt 2 and material pressing belt 3 are made up of a motor and double output shaft gear-box in the high speed course of conveying, guarantee two belts to the operation of crushing shell direction, and velocity magnitude equates.Under the drive of motor, penetrate at a high speed, clash into mutually, thereby the coal in the raw coal is separated with spoil with crushing shell raw coal is sent to discharging opening fast with uniform velocity.Motor can be adjusted transporting velocity by frequency converter, so that material obtains different stroke speeds.The bastard coal mixture is during with the high-speed impact crushing shell, because the nonhomogeneous hardness of bastard coal, in the speed of service is under the material impact velocity situation of 6～15m/s, impulsive force makes the lower coarse coal percentage of damage of hardness bigger, and the higher bulk spoil percentage of damage of hardness is lower, and after the material behind the bump fell into sieve plate, broken coal saw through sieve aperture and falls into fortune coal belt, be that broken spoil flows into the spoil conveyer belt on the sieve, coal is separated with spoil.
