Description

Technical Field

[0001] The utility model relates to the technical field of coal transportation, in particular to a buffer dust removal device for a coal dropping point of a belt conveyor. Background Art

[0002] Coal is a solid combustible mineral that is gradually formed by ancient plants buried underground and undergoing complex biochemical and physicochemical changes. Coal is hailed as black gold and food for industry. It has been one of the main energy sources used by the human world since the 18th century. Since the 21st century, although the value of coal is not as high as before, it has been one of the indispensable sources of energy for our production and life for a long time. The supply of coal is also related to the stability of the development of our country's industry and even all aspects of society as a whole.

[0003] A buffer dust removal device for a coal dropping point of a belt conveyor with the publication number CN220033025U comprises a bracket plate, one end of the side surface of the bracket plate is fixedly connected to a buffer assembly, the middle part of the side surface of the bracket plate is fixedly connected to a sprinkler assembly, both ends of the side surface of the bracket plate are fixedly connected to rollers, both sides of the bracket plate are fixedly connected to support rods, one end of the support rods is fixedly connected to a connecting plate, one side of the connecting plate is fixedly connected to a scraper plate, the buffer assembly comprises a box frame fixedly connected to the bracket plate, and the inner side wall of the box frame is fixedly connected to a support rod plate. The buffer dust removal device at the coal dropping point of the belt conveyor can effectively reduce the impact of coal blocks on the conveyor belt through the arrangement of buffer components and water sprinkling components, thereby extending the practical life of the conveyor belt. The water sprinkling component can effectively reduce the dust generated by coal blocks during transportation, thereby avoiding the impact of dust on surrounding personnel and machinery. However, the buffer dust removal device at the coal dropping point of the above-mentioned belt conveyor has a poor buffering effect due to its relatively simple structure. The single spring and support rod plate are easy to bounce repeatedly when in contact with the coal, causing the coal to be shaken up a second time, aggravating the dust raising. At the same time, water sprinkling for dust removal will still raise the scattered dust after it dries. If water sprinkling is continued, the surrounding soil will become soft and affect newcomers passing by. At the same time, the coal slag powder in the later stage still needs to be collected a second time, which is relatively cumbersome. Therefore, it is necessary to provide a new buffer dust removal device at the coal dropping point of the belt conveyor to solve the above-mentioned technical problems. Utility Model Content
