The utility model aims to solve the technical problem that to the defect that prior art exists, a wet mill feed seal structure of stifled thick liquid of multilayer segmentation is provided.
In order to solve the technical problem, the utility model provides a feeding sealing structure of a wet mill, which comprises a feeding chute, a sleeve, a gland, a lip seal, a retainer ring, a sealing ring, round rubber and a feeding bushing, wherein the feeding bushing and the gland are arranged on the sleeve to form a sealing cavity, and the round rubber is arranged between the sleeve and the feeding bushing to form a first seal; a sealing ring is arranged between the sleeve and the feeding lining to form a second seal; lip seals and check rings are arranged among the gland, the sleeve and the feeding bush to form a third seal; when the mill normally starts, the feeding chute, the sleeve, the sealing ring and the round rubber are static relative to the mill, and the lip-shaped seal, the retaining ring, the feeding lining and the end cover rotate together.
The first sealing middle round rubber, the sleeve and the feeding bushing are tightly matched together.
And the sleeve and the sealing ring are in interference fit in the second seal, and a gap exists between the sealing ring and the feeding bushing.
The third seal is characterized in that the gland is in interference fit with the feeding bushing, the lip seal is in interference fit with the gland, and the check ring is in interference fit with the feeding bushing; the gland, feed bushing and lip seal rotate with the barrel.
The feeding chute is welded with the sleeve. And the surface roughness of the outer surface of the sleeve is Ra0.8.
The clearance between the retainer ring and the sleeve is 3 mm.
A gap exists between the sealing ring and the feeding lining, and the sealing ring can be used for sealing between the feeding chute and the feeding lining; but also reduce the abrasion of the sealing ring.
Has the advantages that: the utility model discloses the effectual hourglass thick liquid phenomenon that frequently appears in the solution wet mill operation process has practiced thrift manufacturing cost, has improved the performance of enterprises.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partially enlarged view of the sealing portion.
The utility model provides a wet mill feeding sealing structure, which comprises a feeding chute 1, a sleeve 2, a gland 3, a lip seal 4, a retainer ring 5, a sealing ring 6, a round rubber 7 and a feeding bush 8, wherein the feeding bush 8 and the gland 3 are arranged on the sleeve 2 to form a sealing cavity, and the round rubber 7 is arranged between the sleeve 2 and the feeding bush 8 to form a first sealing; a sealing ring 6 is arranged between the sleeve 2 and the feeding bush 8 to form a second seal; a lip seal 4 and a retainer ring 5 are arranged among the gland 3, the sleeve 2 and the feeding bush 8 to form a third seal; when the mill normally starts, the feeding chute 1, the sleeve 2, the sealing ring 6 and the round rubber 7 are static relative to the mill, and the lip seal 4, the check ring 5 and the feeding lining 8 rotate together with the end cover.
The first sealing is formed by tightly matching the round rubber 7, the sleeve 2 and the feeding bushing 8 together and is used for sealing the feeding chute 1 and the feeding bushing 8.
And the sleeve 2 and the sealing ring 6 are in interference fit in the second seal, and a gap exists between the sealing ring 6 and the feeding bushing 8.
In the third seal, the gland 3 is in interference fit with the feeding bushing 8, and the lip seal 4 is in interference fit with the gland 3 and is used for sealing between the feeding chute 1 and the feeding bushing 8; the retainer ring 5 and the feeding bush 8 are in interference fit; the gland 3, feed bushing 8 and lip seal 4 will rotate with the barrel.
The feeding chute 11 and the sleeve 2 are welded together, and the surface roughness of the outer surface of the sleeve 2 is Ra0.8.
The clearance between the retainer ring 5 and the sleeve 2 is 3mm, and the retainer ring is used for sealing between the feeding chute 1 and the feeding lining 8.
A gap exists between the sealing ring 6 and the feeding lining 8, and the sealing ring can be used for sealing between the feeding chute and the feeding lining; but also reduce the abrasion of the sealing ring.
When the grinder normally operates, slurry can enter the barrel along the feeding chute 1, and when the slurry in the barrel is higher than the lowest part of the inner diameter of the feeding chute 1, the slurry can flow outwards along the gap between the feeding chute 1 and the feeding lining 8. The round rubber 7, the sleeve 2 and the feeding bushing 8 are in close contact to form a first seal, the surface roughness of the outer surface of the sleeve 2 is Ra0.8, the lower the surface roughness is, the better the sealing effect is, and the longer the service life of the round rubber 7 is.
The tight contact between sleeve 2, sealing washer 6 and the feeding bush 8 forms the second and seals, is interference fit between sleeve 2 and the sealing washer 6, and is gapped between sealing washer 6 and the feeding bush 8, can prevent that the wearing and tearing sealing washer 6 when feeding bush 8 rotates, can play sealed effect again.
Through the three sealing structures, the slurry leakage phenomenon frequently occurring in the operation process of the wet mill can be effectively solved, the production cost is saved, and the enterprise benefit is improved.
The above embodiments of the present invention are merely examples, not the only ones, and all changes within the scope of the present invention or the same range of the present invention are all surrounded by the present invention.
