In groove B on sealing ring one side.
Described overflowball mill or the sealing structure of the feed forced water of rod mill, set in the inner barrel of ball mill
There is a rubber slab, the rubber slab is in contact setting with the inclined-plane of sealing ring another side.
Described overflowball mill or the sealing structure of the feed forced water of rod mill, in the oblique of sealing ring another side
Face is provided with groove A, and lubricating grease is provided with groove A.
Described overflowball mill or the sealing structure of the feed forced water of rod mill, on sealing ring along the circumferential direction
Multiple apopores are interval with, it is circumferentially spaced provided with multiple screwed holes in the side of apopore, in the another of apopore
Side is circumferentially spaced to be provided with multiple top wire holes.
Described overflowball mill or the sealing structure of the feed forced water of rod mill, described multiple screwed holes are with entering
Water lines are connected.
By adopting the above-described technical solution, the present invention has the advantages that：
1st, it is of the invention by being provided with waterproof sealing between the side of sealing ring and feed bend pipe, and will by bolt assembly
Sealing clamp is fixed on sealing ring, prevents the sealed ring of ore pulp with being revealed in the gap of feed bend pipe.
2nd, the present invention by the sealing ring that is fixed on feed bend pipe with grinding machine together with both rubber slabs for rotating compress,
When rubber slab weares and teares, sealing ring is adjusted by jackscrew, makes rubber slab be adjacent to sealing ring all the time to strengthen sealing effectiveness.
3rd, the present invention sets lubricating grease by being provided with depression on the inclined-plane of sealing ring, and in depression and on inclined-plane,
Lubrication is played, the degree of wear of rubber slab is reduced.
4th, the present invention on sealing ring by setting apopore and screwed hole, and screwed hole is connected with inlet pipeline, due to
Water enters to have more less, therefore forms hydraulic pressure in sealing ring, can prevent that ore pulp is excessive and is forced to push back inner barrel.
