Abstract

The utility model relates to a gangue crushing device, which belongs to the field of crushing mechanical devices. The utility model is characterized in that a novel crushing device is formed by that a vertical shaft type crushing mode and a hammer-type crushing mode are combined. The device solves the defect that originally, only a hammer-type crushing device is used for processing gangue with low efficiency, large device investment, frequent device maintenance and high energy consumption. The utility model is especially suitable for gangue crushing before bricks are made in brick-making enterprises with the gangue.

Description

A kind of gangue disintegrating apparatus

The utility model relates to a kind of gangue disintegrating apparatus, in particular for before the making coal gangue brick colliery powder being broken to the gangue disintegrating apparatus that meets the brickmaking requirement.

The diameter of the gangue pellet that the processing colliery wastes brick is used generally is below 2 millimeters; generally be to use hammer mill with the used equipment of broken gangue before the making coal gangue brick now; the characteristics of hammer mill are that himself has screen cloth; the satisfactory material of particle size after cracking can be discharged at any time; the material that granularity does not reach requirement needs in disintegrating machine broken repeatedly till its granularity meets the requirements; hammer mill also exists many defectives; major defect is that tup damages soon; grating is changed frequent; crushing efficiency is lower, needs frequent shutdown maintain and replace accessory, at a medium scale gangue brick field; need to install many hammer mills; wherein half equipment uses, second half maintenance of equipment, and exchange in eight hours is once; and many disintegrating machines use equipment investment bigger simultaneously; general power is big, the energy consumption height, and maintenance cost is big; it is more to take service worker, and service worker labour intensity is bigger.

The purpose of this utility model is to provide a kind of equipment investment few, and energy consumption is low, does not need frequent maintenance and the high gangue disintegrating apparatus of crushing efficiency.

The utility model is realized in the following manner.

A kind of gangue disintegrating apparatus, form by the hammer crushing device, a side that it is characterized in that said hammer crushing device is provided with installing rack, above installing rack, be provided with the vertical shaft breaker, be provided with vibratory sieve in the installing rack below the vertical shaft breaker, the coarse fodder outlet usefulness chute of vibratory sieve is connected with the charge door of hammer crushing device, the coarse fodder outlet of vibratory sieve is positioned at the top of hammer crushing device charge door, and the below of vibratory sieve and hammer crushing device is communicated with the aging bunker of its below respectively.

The said gangue disintegrating apparatus of the utility model is characterized in that between vertical shaft breaker and vibratory sieve, between vibratory sieve fines outlet and the aging bunker, all is communicated with the sealing bag sealing between the outlet of vibratory sieve coarse fodder and the chute.

Because the ratio of reduction of vertical shaft breaker is more much bigger than the ratio of reduction of hammer crushing device, thereby most of gangue is crushed to the brickmaking desired particle size and falls into aging bunker by screen cloth in the vertical shaft breaker, remaining defective coarse fodder granularity also significantly reduces, and enter the hammer crushing device through chute, owing to enter the material of hammer crushing device is material broken through vertical shaft breaker one-level and through sieving, these raw meal particle sizes are little, quantity is few, therefore the tup of hammer mill and the wearing and tearing of screen cloth slow down greatly, its service life and maintenance cycle prolong greatly, production efficiency improves a lot, the working ability of such cover gangue disintegrating apparatus can surpass the working ability of 3 to 5 hammer mills, and its used power and energy consumption reduce at double, and the also corresponding minimizing of maintenance of equipment work amount is a lot.

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing is a kind of structural representation of gangue disintegrating apparatus.

A kind of gangue disintegrating apparatus, comprise hammer crushing device 7, vertical shaft breaker 1, vibratory sieve 10 and installing rack 3, installing rack 3 is positioned at a side of hammer crushing device 7, the vertical shaft breaker is installed in the top of installing rack 3, its blanking port is communicated with by sealing bag 2 with the charge door of the vibratory sieve 10 that is positioned at installing rack 3, the fines outlet 9 of vibratory sieve 10 is communicated with aging bunker by sealing bag 8, the coarse fodder outlet 4 of vibratory sieve 10 is positioned at the least significant end of vibration screen and is higher than the chute 6 of hammer crushing device 7 tops, be communicated with sealing bag 5 between coarse fodder outlet 4 and the chute 6, be provided with screen cloth in the hammer crushing device 7, the fines outlet of its below is communicated with aging bunker.

The gangue disintegrating apparatus is when work, the gangue coarse fodder adds from the top of vertical shaft breaker 1, material after the 1 one-level fragmentation of vertical shaft breaker sieves by the vibratory sieve 10 that gravity falls into its below, granularity meets the requirements of material and falls into aging bunker by screen cloth and sealing bag 8, granularity does not reach the coarse fodder of requirement along screen cloth, enter hammer crushing device 7 by coarse fodder outlet 4 and chute 6, coarse fodder falls into aging bunker from the bottom of breaker 7 after the two-stage crushing raw meal particle size reaches requirement in hammer crushing device 7.This gangue disintegrating apparatus respectively installs connecting portion the sealing bag sealing, can prevent flour dust overflow, improves working environment.

Claims

1, a kind of gangue disintegrating apparatus, form by the hammer crushing device, a side that it is characterized in that said hammer crushing device is provided with installing rack, the vertical shaft breaker is installed above installing rack, be provided with vibratory sieve in the installing rack below the vertical shaft breaker, the coarse fodder outlet of vibratory sieve connects with the charge door of hammer crushing device with chute, the coarse fodder outlet of vibratory sieve is positioned at the top of hammer crushing device charge door, and vibratory sieve and hammer crushing apparatus lower part are not communicated with the aging bunker of its below.

2, according to the said gangue disintegrating apparatus of claim 1, it is characterized in that between vertical shaft fractionation plant and the vibratory sieve, between vibratory sieve fines outlet and the aging bunker, all be communicated with between the outlet of vibratory sieve coarse fodder and the chute with the sealing bag sealing.
