Description
Technical field
The invention belongs to Solid Waste Treatment and Resources and utilize apparatus field, particularly 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 contain certain combustible in gangue, issue and be conigenous combustion in suitable condition, 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, at first must be by the gangue fragmentation, and then the 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 the 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, cause the utilization of resources value of gangue to be underestimated, and then make China because the environmental pollution that gangue causes constantly aggravates.
Gangue forms by the coal component higher containing coal with containing the lower spoil component of coal, and the hardness of coal component is much lower than the spoil component.Therefore can utilize suitable device that gangue is carried out to selective crushing, make spoil component that in gangue, hardness is large keep complete and coal component that hardness is little is completely broken or substantially broken, and then utilize sieve granularity is little, calorific value is high containing the 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
Purpose of the present invention is for the problem that solves above-mentioned existing apparatus and exist and 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, and the 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 the 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, the 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 by the coal component fragmentation in gangue, and keeps the integrality of spoil component, makes it reach the 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 invention, gangue is from the 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 the 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 the deflector changed course.Because the speed of the gangue be thrown out of is larger, outwards continue motion final arrival in the eddy current storehouse after two-part gangue collision, 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 makes the coal component make a distinction with the 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 the eddy current storehouse, thereby landing is to the 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 equipped 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 be thrown out of, improve collision efficiency, contribute to realize allowing two parts gangue bumped form eddy current in its storehouse simultaneously.
Compared with prior art, from above technology, traditional breaker can only carry out simple broken work in the present invention, and each component of finished product is owing to not distinguished on granularity, so the sorting of finished product becomes extremely difficult.Apparatus of the present invention have 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 sorted out more traditional crusher in crushing on value is wanted.The crumbling method of this device is the collision fragmentation of " stone-crash-stone ", and in shattering process, the gangue outer cover of contact device not substantially, therefore, compare with traditional breaker, and the device course of work of the present invention is comparatively stable, and rate of breakdown is lower.
