Dynamic and static ring sealing retainer structure of coal mill

Abstract

The utility model provides a coal mill dynamic and static ring sealing retainer structure, which relates to the technical field of coal mills and comprises a coal mill cylinder wall, a support plate is fixedly mounted on the outer surface wall of the coal mill cylinder wall, and a group of holes I are formed in the outer surface wall of the coal mill cylinder wall. According to the utility model, lubricating oil in the liquid storage tank can be sprayed out through a group of spray pipes through the operation of the water pump, and the spray pipes adopt conical structures, so that the lubricating oil can better enter the joint of the movable ring and the static ring, the friction surfaces between the movable ring and the static ring can be fully lubricated, and the abrasion caused by insufficient local lubrication is reduced; a group of spray pipes are uniformly distributed above the joint of the movable ring and the static ring, so that lubricating oil is uniformly distributed between the movable ring and the static ring, uniform lubrication of the movable ring and the static ring is ensured, abrasion between the movable ring and the static ring is reduced, the sealing performance of the sealing retainer is enhanced, and the leakage risk is reduced; and meanwhile, a weight sensor can timely inform a worker to supplement the lubricating oil when the lubricating oil in the liquid storage tank is too little.
