Abstract
The utility model provides a sealing device for a ball mill, comprising an end cover and a lining connected with the end cover by a flange. The sealing device is characterized in that the contacting surface of the end cover and the lining is provided with a sealing ring. In the utility model, the sealing ring is arranged between the contacting surfaces of the end cover and the lining of the ball mill and the sealing ring is compacted by adjusting the quantity of the washers at the flange connecting part of the end cover and the lining, therefore, the sealing effect of the ball mill can be improved greatly, the pulp can be prevented from entering the hollow chamber between the end cover and the lining; the service life of the end cover and the lining can be improved, and the production cost can be reduced.
Description
Technical field
The utility model relates to a kind of sealing device, relates in particular to a kind of ball mill by wet process sealing device.
Background technology
At present, commercially available ball mill by wet process is to be connected with the lining flange by end cap to seal, and being connected to hard connection the between the contact-making surface of end cap and lining, owing in the ball mill by wet process large quantity of moisture is arranged, therefore, often there is slip between the contact-making surface of described end cap and lining, to spill, enters the cavity between end cap and the lining, slip enters behind this cavity can corrosion end cap and lining, causes when changing after the liner wear because of corrosion and slip block to be difficult to dismounting.
The utility model content:
The purpose of this utility model is to provide a kind of ball mill sealing device of good seal performance.
The purpose of this utility model is achieved in that a kind of ball mill sealing device, comprise end cap with described end cap by the lining that flange is connected, it is characterized in that: the contact-making surface of described end cap and described lining is provided with sealing ring.
In order to improve sealing effectiveness, above-mentioned sealing ring circumferentially is arranged in the annular seal groove at contact-making surface place of described end cover of ball mill and described lining.
For reliable operation, above-mentioned seal groove is arranged on the cylindrical wall of the inner round wall of above-mentioned end cap and above-mentioned lining.
For the gap and convenient installation that reduce end cap and lining, above-mentioned contact-making surface is the conical surface.
In order further to improve sealing effectiveness, above-mentioned sealing ring is a flexible seal ring, and described sealing ring material can be selected according to grinding material character.
In order to compress sealing ring, the flange connections of above-mentioned end cap and above-mentioned lining is provided with pad, determines pad quantity according to the actual measurement size during installation, and sealing ring is compressed.
The utility model has following beneficial effect, the utility model is provided with sealing ring between the contact-making surface of end cover of ball mill and described lining, and the pad quantity of the flange connections by adjusting end cap and above-mentioned lining compresses sealing ring, increased substantially the ball mill sealing effectiveness, can avoid slip to enter cavity between end cap and the lining, improve the service life of end cap and lining, reduced production cost.
Description of drawings
Accompanying drawing 1 is the utility model example structure schematic diagram.
