Dual sealing device for feeding of ball mill

Abstract

The invention provides a dual sealing device for feeding of a ball mill, which is applied in the technical field of large-scale ball mills. The sealing device comprises an inlet pipe, an auxiliary mounting beam, connecting bolts, a compressing snap ring, compressing angle sealing rubber, an adjusting bolt, a mounting flange, an inner wear resistant rubber slab, an outer wear resistant rubber slab, a compressing plate, a compressing plate bolt, a mounting flange bolt and a feeding bushing. The invention is characterized in that: the dual sealing device for feeding of a ball mill is formed by assembling the auxiliary mounting beam, the mounting flange, the inner wear resistant rubber slab, the compressing plate, the outer wear resistant rubber slab and the compressing angle sealing rubber; during installation, the mounting flange is fixed on the inlet pipe through the auxiliary mounting beam, the compressing angle sealing rubber is fixed on a feeding pipe through the compressing snap ring, one side of the compressing angle sealing rubber parallelly contacts with the inner wear resistant rubber slab, and the other side of the compressing angle sealing rubber contacts with a slope of the outer wear resistant rubber slab. According to the invention, the movable compressing angle sealing rubber, the twofold contacted inner and outer wear resistant rubber slabs and the detachable auxiliary mounting beam are utilized in the dual sealing device; therefore, the advantages of convenient installation, simple adjusting and improvement of work environment for sealing members are obtained.

Description

technical field [0001] The invention relates to a mechanical sealing device for a feed end of a wet grid type ball mill or a wet overflow type ball mill in the technical field of large ball mills. Background technique [0002] At present, there is relative sliding between the feed pipe and the feed port of the ball mill during production and use, and slurry leakage is common, resulting in a bad operating environment. The main cause of slurry leakage is that the rotating seal is in direct contact with the unclean surface of the stationary feeding pipe, causing serious wear of the seal, and it is difficult to adjust after a small amount of wear; this sealing method leads to frequent replacement and affects work efficiency. Therefore, researching and developing a kind of ball mill feeding double sealing device is a new subject to be solved urgently always.
