Automatic feeding and dust removing integrating equipment of concrete pump for mine

Abstract

The invention discloses automatic feeding and dust removing integrating equipment of a concrete pump for mine and relates to matched feeding and dust removing integrating equipment for a novel gob-side entry retaining filling technique. The automatic feeding and dust removing integrating equipment of the concrete pump for mine comprises a stand, a primary belt type conveyor, a vibrating sieve, a secondary belt type conveyor, a filling pump and a wet type vibrating string dust remover; a group of dust-proof covers is arranged above each of the primary belt type conveyor and secondary belt type conveyor, each group of dust-proof covers comprises two segments of rectangular sealing dust-proof covers and one segment of organic glass dust-proof cover, the two segments of rectangular sealing dust-proof covers are respectively connected with the stand, the organic glass dust-proof cover is hinged to the stand through a hinge, the organic glass dust-proof cover is arranged between the two segments of rectangular sealing dust-proof covers, a sealing ring is arranged between each segment of rectangular sealing dust-proof cover and the organic glass dust-proof cover, and the organic glass dust-proof cover is connected with a handle. The automatic feeding and dust removing integrating equipment of the concrete pump for mine is capable of preventing dust diffusion, the material bag transportation situation in the belt type conveyors can be observed through the organic glass dust-proof covers, and dust in the belt type conveyors can be cleaned conveniently.

Description

technical field [0001] The invention relates to an integrated integrated equipment for material feeding and dust removal which is matched with a new filling process of gob-side retaining entry, and is applied to the filling process in underground coal mines. Background technique [0002] In order to recover the security coal pillars left in the goaf and maximize the utilization of resources, a new technology of retaining roadways along gobs was developed and achieved success. At present, it is gradually being popularized and promoted to major production mines. However, in this process, the work intensity is high and a large amount of dust is generated when manually dumping the filling material on the belt conveyor, which pollutes the underground working environment of the coal mine, affects safe production, and endangers the health of workers. [0003] There are also some automatic feeding and dust removal equipment at present, but there are the following defects: 1. There ...

AI Technical Summary

Problems solved by technology

However, in this process, the work intensity is high and a large amount of dust is generated when manually dumping the filler on the belt conveyor, which pollutes the working environment of the coal mine, affects safe production, and endangers the health of workers.

[0003] At present, there are also some automatic feeding and dust removal equipment, but there are the following defects: 1. There is a lot of dust when feeding

2. It is impossible to know the distance between the material package on the belt conveyor

3. The conveying efficiency of the first-level belt conveyor cannot be improved. When the material bag enters the vibrating screen, the speed of the first-level belt conveyor cannot be controlled when it is overweight, and the first-level belt conveyor cannot be controlled when the weight is not up to the limit. speed

4. The conveying efficiency of the secondary belt conveyor cannot be improved

5. It cannot be automatically adjusted according to the size of the dust, resulting in poor dust control effect or waste

6. It is easy to generate dust at the vibrating screen, and it is also easy to generate dust when it enters the secondary belt conveyor from the vibrating screen

7. The dust removal pressure of the wet vibrating wire dust collector is high, which affects the dust removal effect
