Abstract
A down-hole breaking and sieving coal gangue separator comprises a housing, a material inlet and a coal gangue outlet. An impact breaking hammer is provided below a material inlet hopper in the housing. An inner wall of housing at the rotation direction side of the impact breaking hammer is provided with an impact plate. A rotary type material pulling wheel is provided at the coal gangue outlet side in the housing. A bottom frame in the housing is obliquely provided an elastic rod sieve which is corresponding with the positions of the rotary type material pulling wheel and the impact breaking hammer. Two sides of the elastic rod sieve are arc-shaped. A bracket at the outer lower part of the bottom frame is respectively provided with the following components: an explosion-preventing motor which drives a material pulling transmission device, and an explosion-preventing adjustable speed motor which drives a breaking transmission device. The down-hole breaking and sieving coal gangue separator can directly separate the coal gangue underground so the large coal gangues are not conveyed out from the hole and can be directly used for filling the goaf. The down-hole breaking and sieving coal gangue separator has the following advantages: reduced transportation cost, reduced occupation of ground land, ground subsidence prevention, reduced expenditure for environment improvement, reduced environment pollution, saved down-hole and up-hole transportation amount of goal gangue, simple and compact device, convenient detachment and good separation effect.
Description
Technical field
The utility model relates to the crushing and screening gangue separator, especially a kind of crushing type gangue separator that directly applies to colliery underground lump and gangue sorting.
Background technology
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.Present coal separates with gangue, and common method for separating has selection by winnowing, the gamma ray sorting, and the jigging sorting, sorting heavily is situated between.Wherein: selection by winnowing is to utilize coal different with spoil density, produces coal and spoil by the buoyancy separation of wind, is applicable to the area of water resource poorness.Its investment is big, and floor space is big, and dust-reclamiing mill is bigger, and treatment effect is undesirable, is not suitable for the down-hole and uses.The sorting of gamma ray bastard coal is to adopt gamma rays 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, change the movement locus of spoil, thereby the experiment bastard coal separates.Its system complex, sorting capability is little, and the radiation hidden danger of radioactive source often contains water or coal slime in the on-the-spot raw coal, and coal cinder spoil surface is covered by coal slime, causes the difficulty in the identification.The jigging sorting is to make the coal in the raw coal go up lower leaf because of density is different with spoil to the pulsation medium that utilizes vertical alternation below the selected upper limit then (general water) the feed coal primary fragmentation earlier, finally realizes the separation of the two.This technological process to contain the cash amount in the raw coal be not very big and spoil hardness is medium, be difficult for argillization in to contain the cash raw coal more suitable.But also there are shortcomings such as sharpness of separation is low, unstable product quality, the impurity band coal losses is big, coal washing efficient is low.Simultaneously because the down-hole use greatly again of complex process equipment volume.The sorting that heavily is situated between is that the buoyancy size of utilizing solid to be subjected in liquid medium equals it and arranges weight with the volume medium, density is sunk among the medium greater than the solid particle of Media density, and density swims on the medium less than the solid particle of Media density, realizes the separation of two kinds of solid particles.Major defect is that process system complexity, equipment attrition are serious, investment is big, production cost is high.And its complicated technology makes that also the sink float cash at all can't be in down-hole application.
