[0002] Coal is a very important energy source and an important raw material for the metallurgical and chemical industries. During the clean coal processing, the coal needs to be washed through a coal washing device. The higher the gangue content of the clean coal, the higher the ash content of the clean coal, and the lower the recovery rate; the lower the gangue content of the clean coal, the higher the clean coal recovery rate. Therefore, during the clean coal processing, the coal will be washed through a coal washing device to reduce the gangue content of the clean coal.
[0003] At present, during the processing of clean coal, the coal is usually washed by a coal washing device. When the coal washing device is washing the coal, the drop plate and the square wetting box above the cone will block the rotation force of the suspension and destroy the air column above, thereby reducing the coal washing effect of the coal washing device. Therefore, a device is needed to reduce the gangue content of the clean coal. By adding a self-cleaning cylindrical barrel body, the rotation height and stirring force of the suspension can be increased to form a higher air column, so as to avoid that the less space above the cone will reduce the effect of coal washing. At the same time, the round tube barrel body has a self-cleaning structure to prevent the coal mixture from sticking to its inner wall for a long time and agglomerating, which is inconvenient to clean. The coal washing effect of the coal washing device is improved and the cleanliness of the inner wall of the cylindrical barrel is ensured. Utility Model Content
