Coal mine guniting dust removal equipment

Abstract

The invention discloses coal mine guniting dust removal equipment, which comprises a transport vehicle, a spraying device, a spraying device and a dust removal device, the guniting mechanism comprises a storage tank arranged on the transport vehicle, one side of the bottom of the storage tank is communicated with a guniting pipe, and a guniting head is arranged at the end of the guniting pipe; the dust removal mechanism comprises a collecting pipe, the collecting pipe is connected to the outer ring of the guniting pipe in a sleeving mode, a collecting cover is arranged at the end, close to the guniting head, of the collecting pipe, a collecting hole is formed in the outer ring of the collecting cover, the collecting hole communicates with an inner cavity of the collecting cover, and the other end of the collecting pipe is connected with a collecting and filtering mechanism; the collecting holes are formed in the outer side of the collecting cover, the collecting holes in the outer side absorb dust splashed on the outer ring, the situation that the collecting device is close to the guniting head and absorbs splashed cement together is avoided, blocking of the guniting holes is avoided, cement flying dust is better absorbed, and diffusion is avoided.

Description

Technical field [0001] The present invention relates to the field of coal mine technology, in particular to a coal mine slurry dust removal equipment. Background [0002] Sprayer is a new type of efficient spraying machinery, mainly through the rotor type concrete sprayer, cement slurry mixer, extrusion type cement slurry pump, electrical control box, discharge elbow, pneumatic system, mixing device, spray gun, frame and other parts of the composition, mainly suitable for the concrete spraying operation of the cross-sectional roadway, the cement slurry from the mud pump and the sand and gravel sprayed by the sprayer, the quick-setting agent is mixed in the mixer, and then the mixture is sent to the spray gun by the conveyor pipe for spraying operations, and a large amount of cement dust will be generated when the spraying operation is carried out. Pollute the working environment, causing certain harm to the human body, the existing dust removal equipment is usually in the end of ...

Problems solved by technology

[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 mainly used for the concrete spraying operation of the 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 the mixed material is transported by the conveying pipe. After being sent to the spray gun for spraying operation, a large amount of cement dust will be generated during the spraying operation, which will pollute the working environment and cause certain harm to the human body. The existing dust removal equipment is usually equipped with a dust suction port on the outer ring of the end of the spray pipe , to absorb the generated dust, but in the process of use, it will absorb the splashed cement together, which is easy to cause blockage
