Description

Technical Field

[0001] The utility model relates to the technical field of coal processing, in particular to a conveying device for coal washing and processing. Background Technique

[0002] Coal is an important energy source and industrial raw material with extensive applications. Through chemical processing, thousands of chemical products can be produced from coal. In power plants, coal combustion generates steam, and the steam drives a turbine generator to generate electricity. Although coal has certain impacts on the environment and health, such as air pollution and greenhouse gas emissions, under the current technical and economic conditions, coal remains an indispensable energy source.

[0003] Most of the currently used conveying devices do not have the function of cleaning residues themselves. Since coal residues remain on the surface of the conveyor belt for a long time and accumulate continuously, it eventually leads to difficult cleaning. At the same time, coal contains acidic components. If not cleaned in time, it will reduce the service life of the conveyor belt and is prone to form coal dust accumulation. When the coal dust accumulates to a certain extent, it is easy to form a combustible mixture, increasing the risk of fire. Content of the Utility Model

Next, when the transmission belt 132 rotates, the second belt pulley 133 can be driven to rotate. When the second belt pulley 133 rotates, the connecting rod 134 can be driven to rotate. Then, when the connecting rod 134 rotates, the first meshing gear set 135 can be rotated. Then, when the first meshing gear set 135 rotates, the transmission rod 136 can be driven to rotate. When the transmission rod 136 rotates, the second meshing gear set 137 can be driven to rotate. When the second meshing gear set 137 rotates, the rotating rod 15 can be rotated. Next, when the rotating rod 15 rotates, the sponge sleeve 16 can be driven to rotate.
