Description
Technical field
The utility model belongs to Solid Waste Treatment and Resources and utilizes apparatus field, be particularly related to a kind of breaker for coal gangues automation selection, be specifically related to gangue after fragmentation, sub-elect wherein containing the higher component of coal, to realize the recycling of gangue.
Background technology
More than 1500 of the existing hillocks in state-owned colliery, the whole nation, accumulating amount is more than 3,000,000,000 tons.A large amount of stackings of gangue, not only cover soil, influence ecological environment, spoil leaching water will pollute surrounding soil and underground water, and in gangue, contain certain combustible, in suitable condition, issue and be conigenous combustion, the pernicious gas pollutant atmospheres such as discharge sulfur dioxide, nitrogen oxide, oxycarbide and flue dust, affect the healthy of Residents in Mining Area.
And will turn waste into wealth, first must gangue is broken, and then sorting utilization.Traditional disintegrating machine is consistent to the crushing effect of each composition of gangue, and this has also caused the finished product after fragmentation can not or be difficult to sorting, so make the value of finished product not high, economic benefit is hard to carry on.Although there is subsidy policy in country to the processing of gangue, because actual profit is on the low side, rare enterprise participation, causes the utilization of resources value of gangue to be underestimated, and then makes China because the environmental pollution that gangue causes constantly aggravates.
Gangue is by containing the coal component that coal is higher and forming containing the lower spoil component of coal, and the hardness of coal component is much lower compared with spoil component.Therefore can utilize suitable device that gangue is carried out to selective crushing, make the spoil component that in gangue, hardness is large keep coal component complete and that hardness is little to be completely broken or fragmentation substantially, and then utilize sieve using granularity little, calorific value is high containing coal component screening out as fuel used to generate electricity, the spoil component that remaining granularity is large, calorific value is low can be used as construction material.Like this, both realize the value of gangue, reduced again the pollution that its bulk deposition causes.
Summary of the invention
The purpose of this utility model is in order to solve the problem of above-mentioned existing apparatus existence and to improve problem of environmental pollution, and provide, a kind of crushing efficiency is high, the breaker for coal gangues automation selection of failure rate is low.
A kind of breaker for coal gangues automation selection, comprise outer cover, feeding-distribution device, some deflectors, batch mixing pan, support, it is characterized in that: outer cover is fixed on support, outer cover top is provided with charging aperture, the bottom of outer cover is provided with discharging opening, and the middle part of outer cover is eddy current storehouse; Feeding-distribution device is arranged in charging aperture and eddy current storehouse, and the top of feeding-distribution device is umbrella-shaped structure, the top of feeding-distribution device is provided with charging hole, the gangue of coming in from charging aperture can be to umbrella-shaped structure through the top of feeding-distribution device dispersed, feeding-distribution device middle part is the storage feed bin of gangue, and batch mixing pan is arranged on the below of feeding-distribution device; Some deflectors are arranged on respectively below the umbrella-shaped structure of feeding-distribution device and are fixed on outer cover.This device can be optionally broken by the coal component in gangue, and keep the integrality of spoil component, makes it reach sorting requirement.
A flow control valve is installed in the bottom of described feeding-distribution device.
Described batch mixing pan is by gear component controls rotating speed, can regulate the speed that throws away of rotating speed and the gangue of batch mixing pan.
Breaker for coal gangues automation selection of the present utility model, gangue is from charging aperture access to plant, umbrella-shaped structure effect through feeding-distribution device is divided into two parts by gangue, and a part is glided and final landing by umbrella-shaped structure guiding, and another part directly falls to the feed bin at feeding-distribution device middle part.The gangue of landing bumps against with deflector after the segment distance that glides, and after bumping against, the direction of motion changes, no longer vertical drop, and its velocity vector produces a minute vector at centripetal direction.Gangue in feed bin enters the batch mixing pan of rotation through flow control valve, and because the effect of centrifugal force is thrown out of, its direction upwarps, and bumps with the gangue through deflector changed course.Because the speed of the gangue being thrown out of is larger, after two-part gangue collision, outwards continue motion final arrival in eddy current storehouse, form eddy current and continue to occur collision mutually.Due to this collision of twice shock that is all " stone-crash-stone ", therefore broken is all the coal component that hardness is lower, the spoil component that hardness is larger seldom can be crashed, and then coal component is made a distinction with spoil component on granule size, makes sorting become easy.Gangue completes after fragmentation due to the reduction of speed, and centrifugal force is not enough to support its continuation to stay in eddy current storehouse, thereby landing is to below discharging opening.
The above-mentioned breaker for coal gangues automation selection, wherein: feeding-distribution device top is umbrella-shaped structure, can the gangue of coming in from charging aperture is dispersed, be conducive to improve possibility and the efficiency that two parts gangue clashes into.
The above-mentioned breaker for coal gangues automation selection, wherein: the bottom of feeding-distribution device is provided with flow control valve, controls the ratio that is thrown out of gangue and dropping coal spoil, can regulate the composition proportion of composing in finished product.
The above-mentioned breaker for coal gangues automation selection, wherein: the batch mixing pan that can convert rotary speed can throw away gangue with different speed by specific direction, can adjust best stroke speed, and then regulate the composition proportion of composing in finished product.
The above-mentioned breaker for coal gangues automation selection, wherein: deflector is arranged on below the umbrella-shaped structure of feeding-distribution device, it can change the direction of motion of dropping coal spoil, can with the crashing of the gangue generation smaller angle being thrown out of, improve collision efficiency, contribute to realize allowing two parts gangue having bumped form eddy current in its storehouse simultaneously.
Compared with prior art, from above technology, traditional breaker can only carry out simple broken work to the utility model, and each component of finished product is owing to not distinguishing in granularity, so the sorting of finished product becomes extremely difficult.The utility model device has the component sorting function of gangue, and assorting room is simple, and it is high a lot of that the gangue finished product of each component simultaneously sorting out more traditional crusher in crushing in value is wanted.The crumbling method of this device is that the collision of " stone-crash-stone " is broken, and in shattering process, the gangue outer cover of contact device not substantially, therefore, compares with traditional breaker, and the device course of work of the present utility model is comparatively stable, and rate of breakdown is lower.
