Vertical coal bunker breakage-proof delamination cushioning device

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 toslid 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 endof 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 thespiral 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 [0001] The invention relates to an auxiliary conveying device in an anthracite coal mining coal storage bunker, in particular to a vertical coal bunker anti-fragmentation layered buffer device applicable both underground and above the mine. Background technique [0002] With the increasing shortage of energy in the world and the development of energy and chemical industry, the demand for lump carbon (coal) with relative granularity is growing rapidly. As a coal production enterprise, reducing the damage rate of coal has obvious economic benefits. In the usual coal mine production, in order to adjust the output and export, there are storage and transportation coal bunkers both underground and above the mine. The depth of the coal bunker can be as high as about 30 meters. The lump carbon in the coal bunker is severely damaged, and the lump carbon is reduced from the original 60% to about 20% through the transportation in the bin, seriously affecting the economi...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problem that the anti-shattering conveying device in the existing coal bunker cannot be adjusted due to the angle of the spiral chute: 1. Coal accumulates in the chute during coal chute and cannot be discharged into the bottom of the bunker; The coal slid out of the chute in the middle, and fell directly into the bottom of the bunker, causing lumps of coal to be broken, which could not prevent the coal from breaking, and the spiral chute was not easy to reinforce in the limited space of the coal bunker, and it was difficult to withstand the huge pressure in the coal bunker. Provides a vertical coal bunker anti-fragmentation layered buffer device
