Description
Technical Field
The utility model belongs to the technical field of the environmental protection, concretely relates to belt conveyor dust collector.
Background
In the production processes of ore mining and transportation, ore processing and ironmaking and steelmaking, the belt conveyer is widely applied to conveying of block-shaped or powder-shaped materials.
Dust is generated in the process of conveying materials by the belt conveyor. The cleaning device or the dust removing device of the existing belt conveyer is divided into two types: (1) The cleaning device of the belt conveyer is mainly divided into a fixed scraper sweeper, a rotary rolling brush sweeper, a fixed scraper and a high-pressure nozzle sweeper and is used for cleaning materials attached to the lower surface and the upper surface of a return belt of a machine head of the belt conveyer; (2) The belt conveyor dust removal device mainly comprises a dust removal box body, a fan and a nozzle, and dust generated by coal dust on the upper portion of a belt conveyor in a coal conveying process is removed in a nozzle water spraying mode.
The fixed scraper sweeper scrapes off materials or dust attached to the surface of the belt through the friction effect of the flexible or rigid scraper and the surface of the belt, and except that the materials or dust generated at the unloading position of the belt conveyor head can fall into the material groove, the dust or material part generated by the scraper sweepers positioned at other mounting positions falls into the ground right below the fixed scraper sweeper or part of the fixed scraper sweeper is dissipated into the air.
The rotary rolling brush cleaner is arranged below the belt of the belt conveyor, and materials or dust attached to the surface of the belt are cleaned through rolling friction between the rolling brush and the surface of the belt. The removed material or dust partly falls to the ground and partly escapes to the air.
The fixed brush cleaner is arranged under the belt of the belt conveyor, and materials or dust attached to the surface of the belt are cleaned through friction between the brush and the surface of the belt. The cleaned material or dust falls into the ash bucket right below the sweeper partially, falls into the ground partially and escapes into the air partially. Dust in the ash bucket of the fixed brush cleaner is cleaned in a manual mode.
The fixed scraper and high-pressure nozzle cleaner firstly sprays high-pressure water or gas through the scraper and then the high-pressure nozzle to perform blowing, and then cleans materials or dust attached to the surface of the belt through the scraper. The cleaned material or dust falls partly to the ground and partly escapes to the air under the action of the high-pressure medium.
The belt conveyor dust remover mainly comprises a closed guide chute, a water spray head, a fan and a sewage collecting pipe, is arranged on the upper part of the belt conveyor, and is suitable for the field of coal dust removal. The dust generated in the process of conveying coal by a belt on the upper part of a belt conveyor is removed in a mode of spraying water in a closed guide chute by a water spray head.
After the belt conveyor runs for a period of time, the surface of the belt is abraded and even dimpled, and a part of materials or dust is attached to the concave surface of the belt.
The fixed scraper sweeper cannot effectively remove fine dust or materials on the surface of the belt or in the concave surface of the belt because the contact surface of the fixed scraper sweeper is locally peeled off and has a pit. The fine dust or material on the lower surface of the return belt at the lower part of the belt conveyor is dissipated to the surrounding air along the length direction of the belt in the running process of the belt, so that air dust pollution is caused, and the occupational health of post personnel is harmed.
In the friction cleaning process of the rotary rolling brush cleaner and the surface of the belt, part of dust escapes to the surrounding air along the length direction of the belt, so that air dust pollution is caused, and the post occupational health is harmed. The rotary rolling brush cleaner generates obvious air dust pollution, so the rotary rolling brush cleaner is rarely applied in production practice.
In the friction cleaning process of the fixed brush cleaner and the surface of the belt, part of dust is dissipated to the surrounding air along the length direction of the belt, so that air dust pollution is caused, and the post occupational health is harmed.
When the fixed scraper and the high-pressure nozzle cleaner operate, dust attached to the surface of the belt escapes to the surrounding air under the sweeping action of high-pressure air, so that air dust pollution is caused, and the post occupational health is harmed.
The belt conveyor dust remover is only suitable for the belt conveyor to convey coal and can only remove coal dust generated by an upper belt. The dust remover for the belt conveyor does not consider dust generated on the lower surface of a return belt at the lower part of the belt conveyor.
Along with the increasingly strict management of environment protection on unorganized emission, the belt gallery is gradually changed from the original semi-open type to the fully-closed type, and the phenomenon of air dust pollution caused by the return belt at the lower part of the belt conveyor is increasingly obvious.
