Abstract
The invention relates to an auxiliary delivery device for an anthracite coal mining and storing bin, in particular to a vertical coal bin tatter prevention hierarchical buffer device which is applied to both underground and above ground. The invention solves the problems of the present coal bin tatter prevention delivery device during the transportation of spiral gradient that the coal is easy to slid out of a chute and fall into the bottom of the bin directly to cause the block charcoal crushing, the spiral chute is uneasy to be reinforced in the limited space of the coal bin and bear the large pressure in the coal bin, and etc. The vertical coal bin tatter prevention hierarchical buffer device includes a fixing stent which is reinforced above the coal bin and a spiral chute. The top end of the spiral chute is fixedly connected with the fixing stent through a fixing axis. The internal bending part of the spiral chute is equipped with a plurality of coal gaps. The outer lateral of the spiral chute is equipped with a plurality of connection earrings which are fixedly connected with and fixing stents through fixing rods. The invention is provided with reasonable structure and is applied to the warehousing storage and transportation of mine block coal. The invention greatly lowers the coal crushing rate and is applied to the anthracite coal mines with high requirement for the block coal rate.
Description
Technical field
The present invention relates to the auxiliary conveying appliance in the coal stone coal mining coal store, specifically is a kind of down-hole, the aboveground vertical coal bunker breakage-proof delamination cushioning device that all is suitable for.
Background technology
Along with the development of the in short supply day by day and derived energy chemical of world energy sources, very fast to piece charcoal (coal) demand growth with relative granularity, the breakage rate that reduces coal as coal production enterprise has tangible economic benefit.In the common Coal Production is to adjust output and outward transport, down-hole and the aboveground accumulating coal bunker that all disposes, coal bunker deeply can be up to 30 meters about, when coal is carried in coal bunker through load-transfer device, because huge drop causes the piece charcoal badly broken that falls in the coal bunker, the piece charcoal is carried in the storehouse by original 60% and is reduced to about 20%, has a strong impact on economic benefit of enterprises.As the patent No. is that 01225591.2 Chinese patent discloses " a kind of spiral of vertical coal bunker slip device for coal ", the basic spiral chute that adopts is arranged formation slide device for coal around the center fixation shaft alignment, because its spiral slide coal export structure is limit, the little then coal of chute angle that spiral slips can not be discharged in chute.If transfer the chute angle big then coal centnifugal force in the downslide process in chute can not finely be controlled, coal is gone out again outside the groove halfway, coal can not be sent at the bottom of the storehouse, and be caused the breakage of piece charcoal, does not have piece charcoal shatter prevention effect; The Chinese patent of the patent No. 99211918.9 disclosed " spiral of speed limiting is transferred feedway " for another example, it belongs to exsert ruggedized construction, chute links through reinforcing member and bulkhead, because the down-hole coal bunker with taking to move and build temporarily, is scarcely done permanent maintenance, the pressure that is limited to the down-hole coal bunker is big, the coal bunker mouth is about 2,3 meters, reach 20-30 rice deeply again, thereby the down-hole coal bunker can utilize the space limited, its this structure is difficult to application in practice.
Summary of the invention
The present invention and exists in order to solve breakage-proof feedway in the existing coal bunker because the angle of its spiral chute can't be adjusted: one, coal is piled up in chute in the coal slipping, and can not enter at the bottom of the storehouse; Two, coal skids off outside the chute midway at the slide coal, and cause the fragmentation of piece charcoal at the bottom of directly falling into the storehouse, can not play the coal shatter prevention effect, and spiral chute is difficult for reinforcing, being difficult to bear in the coal bunker problems such as immense pressure in the limited space of coal bunker, and a kind of vertical coal bunker breakage-proof delamination cushioning device is provided.
The present invention adopts following technical scheme to realize: vertical coal bunker breakage-proof delamination cushioning device, comprise and add fixed support, the spiral chute that is fixed in the coal bunker top, the spiral chute top is connected and fixed by anchor shaft and fixed support, and the interior crook of spiral chute has several gap that produces coal; The spiral chute outside is provided with the connection earrings that several are connected and fixed by fixed link and fixed support; The anchor shaft upper end is fixed on the fixed support with fastener.
Coal is delivered to the coal bunker bottom downwards along spiral chute, and coal is in course of conveying, because under the effect of centnifugal force and gravity, coal can stride across the gap that produces coal under effect of inertia, slide downwards smoothly; Form heap taper dump in the coal bunker bottom, the coal of carrying continues along sending under the spiral chute, pile up in the chute of locating above dump, so far, coal produces coal gap via crook in the spiral chute of this accumulation place top, directly fall within on the dump, and slide to the coal bunker bottom along the slope of dump, and cover layer by layer on the dump, make heap taper dump height continue to increase along spiral chute, until filling coal bunker, improved the block coal rate in the whole transportation process; Avoided existing spiral chute in use, coal has taken place, and caused via the load-transfer device of coal bunker feeding mouth at the bottom of coal that coal bunker is carried directly falls into the storehouse outside by chute, not having buffer action along the phenomenon of piling up in the chute; Perhaps excessive because of the chute spiral angle, coal is too fast along rolling speed in the chute, and the coal that causes slipping is gone out outside the groove midway, does not have the breakage-proof purpose of piece charcoal, the breakage rate height.
Compared with prior art, the present invention crook in spiral chute is provided with several gap that produces coal, can not pile up and to cause spiral chute unavailable, or coal is being skidded off outside the chute carrying in the way along groove, cause the situation of piece charcoal fragmentation to occur at the bottom of directly falling into the storehouse owing to the coal on the chute; And the present invention mainly by anchor shaft, fixed link, fixed support and coal bunker upper fixed, easily reinforces in the space content that coal bunker is limited; Be convenient to install and maintenance, the present invention is rational in infrastructure, is applicable to the accumulating of putting in storage of colliery lump coal, has reduced the coal crushing rate widely, is particularly useful for the demanding coal stone of lump coal rate colliery is used.
