Embodiment Construction

[0011] as attached figure 1 , 2 As shown, first install the coal retaining plate 2 on both sides of the belt conveyor frame 1 and between the upper and lower belts 4 and 6, the lower end of the coal retaining plate 2 is slightly inclined inwardly, and the upper end of the coal retaining plate 2 is about 200mm higher than the upper belt 4. About 10mm away from the edge of the upper belt 4, the lower end of the coal retaining plate 2 does not touch the upper surface of the lower belt 6, each coal retaining plate 2 is connected with a flexible rubber plate 11, the flexible rubber plate 11 is in contact with the upper surface of the lower belt 6, and rests on the lower belt 6; on the frame at the front 30 meters of the tail, below the upper belt 4, a coal sprinkling collection baffle 3 is installed in the vertical direction, and the lower edge of the coal sprinkling collection baffle 3 is slightly away from the lower belt 6 surface, and the coal sprinkling is collected The instal...

Abstract

The invention relates to an automatic cleaning method of sprinkled coal in belt conveyance, which comprises the following steps of: firstly installing a coal blocking plate between an upper belt and a lower belt at both sides of the frame of a belt conveyor, installing a sprinkled coal collecting baffle plate in the vertical direction on the frame in front of the tail of the belt conveyor, building a coal falling bin on the ground below the sprinkled coal collecting baffle plate, installing a coal level sensor inside, and connecting a scraper conveyor between the coal falling bin and a coaling hopper; and when the coal level height reaches a set point, starting the scraper conveyor for conveyance, and when a bin level is low, stopping the scraper conveyor, repeatedly circulating, conveying the slipped coal to the upper belt, and entering a coal flow system to finish the whole cleaning process. The method effectively reduces the belt deviation and the equipment abrasion caused by coal sprinkling, saves the maintenance cost, lightens the labor intensity, improves the equipment conveying capacity, greatly reduces the belt replacing investment and solves the difficult problems that cargos with small adhesive force can not be conveyed by a belt and the coal is sprinkled on the belt.

Description

technical field [0001] The invention relates to an automatic cleaning method for belt-sprinkled coal, in particular to a method for automatically cleaning and recovering belt-sprinkled coal, returning to the upper belt and transporting to a coal bunker. Background technique [0002] As the most widely used transportation equipment in the underground production system of coal mines, belts have the advantages of large transportation capacity, long transportation distance, energy saving and small crushing effect on coal. Gangue transportation has all been carried by belts, but with the increase in the application of belts, the limitations of belt transportation have also become prominent. When the coal with high water content is transported and the inclination of the belt is large, the coal will slide and fall off on the roadway or the belt roller, causing The deviation of the belt and the excessive coal spraying in the roadway seriously threaten the normal operation of the equ...
