Preferably, it is connected by helicitic texture between the water injection pipe and the first seal.
Preferably, the aperture of the flushing hole is 4-8mm.
Advantageous effect
The friction portion on drag ring and the second seal in the present invention on the first seal together constitutes mill feeding bend pipe
Annular dynamic seal between grinding mill barrel drag ring in the present invention and rubs relative to mill feeding bend pipe and grinding mill barrel
Wiping portion is taper and cooperates, to avoid the slurry in grinding mill barrel to leak outside in the rotation process of grinding mill barrel.
In a preferred embodiment of the invention, drag ring uses ceramic material, friction portion to use abrasive rubber material
Material makes so that friction is small between drag ring and friction portion, extends the service life of the present invention.Friction portion can pass through
Its elastic property fills up the gap between drag ring, it is ensured that sealing performance of the invention.It is spaced and sets on the first seal
There are multiple flushing holes, the slurry that can avoid splashing in grinding mill barrel flows between drag ring and friction portion and causes to damage, to
Further improve the service life of the present invention.

Specific implementation mode
As shown in Figure 1, a kind of water sealing device for large-sized mining grinding mill feed end of the present invention, including fixed setting
The first seal 4 in 6 periphery of mill feeding bend pipe and the second seal 1 for being fixed at 3 inner circumferential of grinding mill barrel, first is close
Envelope body 4 and the second seal 1 are all made of the making of abrasive rubber material.During mill running, the first seal 4 with grinding machine into
Expect that bend pipe 6 is stationary, the second seal 1 is rotated with grinding mill barrel 3, is formed between the first seal 4 and the second seal 1
The dynamic sealing of annular, to avoid the slurry leakage in cylinder.
First seal 4 is fixed by clip 5 and mill feeding bend pipe 6, and one is internally provided with along mill in the first seal 4
6 circumferentially distributed stainless steel insert 8 of machine feeding bent pipe forms a cavity 401 in the inside of skeleton 8, and the first seal 4 is to vulcanize
Mode include being fixed on the periphery of skeleton 8, so that the first seal 4 and skeleton 8 is securely fixed.First seal 4 is far from grinding machine
The side of cylinder 3 is equipped with the water injection pipe 7 being connected to cavity 401, is lived using helicitic texture between water injection pipe 7 and the first seal 4
Dynamic connection, increases the fixing device of water injection pipe 7 on the screw thread mouth of the first seal 4, to be damaged when water injection pipe 7 being avoided to move
Helicitic texture.
Outer rim of first seal 4 close to the side of grinding mill barrel 3 is set as taper, in the first seal 4 close to grinding machine
The small end of 3 side of cylinder is simultaneously equipped with multiple flushing holes 402 being connected to cavity 401 along the circumferentially-spaced of the first seal 4, rinses
The aperture in hole 402 is 4-8mm.It is set along the circumferential direction of the first seal 4 in big end of first seal 4 close to 3 side of grinding mill barrel
There is mounting groove, be fixed with drag ring 9 by way of being embedded in mounting groove, and keeps the outer rim of drag ring 9 and first close
Taper outer rim of the body 4 close to 3 side of grinding mill barrel is sealed concordantly to be arranged.Drag ring 9 in the present embodiment uses ceramic material,
Purpose is to reduce the frictional force coordinated with the second seal 1, the other wear-resisting and smooth material such as organic glass can also be used
Material.
Second seal 1 includes interconnecting piece 101 for being fixedly connected with grinding mill barrel 3 and for being connect with drag ring 9
Cooperation is touched to form the friction portion 102 of annular dynamic seal.Interconnecting piece 101 is fixedly connected by multiple bolts 2 with grinding mill barrel 3.
The inner edge in friction portion 102 is set as taper corresponding with the outer rim taper of the first seal 4 so that friction portion 102 and friction
It is in close contact between ring 9, arrives sealing purpose.
In the installation process of the present invention, second seal 1 is fixed by bolt 2 first with grinding mill barrel 3, then will
First seal 4 is set in mill feeding bend pipe 6 on the straight section of grinding mill barrel 3, and to the first seal 4 along mill feeding
The direction that bend pipe 6 is axially facing grinding mill barrel 3 applies certain axial force so that and drag ring 9 and friction portion 102 are in close contact,
Form annular taper sealing.First seal 4 can finally be fixed by clip 5, completes installation.Due to the second seal 1
It is made of abrasive rubber material, there is certain elasticity, in addition to the gap between friction portion 102 and drag ring 9 can be filled up
Other than the effect for ensureing sealing, a little shortcoming of mill feeding bend pipe 6 and 3 concentricity of grinding mill barrel also can avoid so that this hair
Bright installation process or adjustment process is extremely convenient and quick.The friction portion 102 of the present invention increases wear-resisting amount using processing is thickened.
After the abrasion to a certain degree of friction portion 102, clip 5 can be unclamped, the first seal 4 is continued towards the second seal
1 direction applies axial force, you can so that being fitted closely again between drag ring 9 and friction portion 102, and then improves the present invention's
The utilization rate of service life and material.
