A Portable Shotcrete Dust Removal Device Used in Coal Mine Roadway

Abstract

The invention discloses a portable spraying and dedusting device used in a coal mine roadway, which includes a vehicle frame, a dust removal and filtering device, a storage barrel and a connection and fixing structure. The vehicle frame, the second rotating disc, the connection groove, the connection plug The block and connection fixing structure can realize the assembly of the dust removal device, which is convenient for carrying and transportation during construction work, and brings convenience when working at different construction sites, facilitates the work of the staff, and improves work efficiency ;The collected dust and impurities can be well collected and stored through the set dust removal filter device and storage barrel, and it is very convenient for the centralized discharge and treatment of dust, which improves the efficiency of dust removal work; through the set of the first rotating disk and the second Two rotating disks and a dust suction cover can carry out multi-angle and multi-directional dust removal work during the dust removal work process, and the work is more flexible, and the dust removal work can be carried out according to the actual working conditions.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a portable spraying dust removal device used in coal mine roadways. Background technique [0002] Shotcrete machine is a new type of high-efficiency spraying machine, mainly through the rotor concrete sprayer, cement slurry mixer, extrusion cement slurry pump, electrical control box, discharge elbow, air system, mixing device, spray gun, It is composed of frame and other parts, and is mainly suitable for the concrete spraying operation of 5m*5m cross-section roadway. The cement slurry from the mud pump is mixed with the sand and quick-setting agent sprayed out by the jet machine in the mixer, and then transported by the delivery pipe. The spraying operation is carried out after the mixture is sent to the spray gun. [0003] During the spraying operation, a large amount of cement dust will be generated, which has multiple hazards: polluting the workplace, endangeri...

AI Technical Summary

Problems solved by technology

[0003] During the spraying operation, a large amount of cement dust will be generated, which has multiple hazards: polluting the workplace, endangering human health, causing occupational diseases; accelerating mechanical wear and shortening the service life of precision instruments; reducing the visibility of the workplace and increasing the occurrence of industrial accidents; Affect the line of sight, and even cause vision loss; therefore, it is very important to carry out relevant dust removal treatment when spraying grouting for developing roadways in coal mines
