Description
Technical Field
The utility model relates to a coal pulverizer welt technical field especially relates to a coal pulverizer welt convenient to equipment.
Background
At present, the well-known liner plate bolt sealing structures on the cylinder body and the end covers at two sides of the coal mill comprise a drum-shaped rubber sealing ring, a cup-shaped steel gasket, a liner plate bolt, a nut and the like. The cup-shaped gasket transmits the axial pressing force of the nut to the drum-shaped rubber sealing ring, and sealing is formed between the coal mill cylinder and the lining plate bolt, so that coal water slurry leakage is prevented. However, with the increase of the running time of the coal mill, the phenomenon of coal water slurry leakage at the bolt holes of the lining plate of the cylinder body can occur due to the inevitable plastic deformation of the rubber material, and when the lining plate is replaced, the bolt sealing structure is damaged, so that time and labor are wasted during the disassembly.
