Abstract
The utility model belongs to the technical field of ball mills, and particularly relates to a feed port sealing device for a ball mill, which comprises a feed liner, a feed end cover, a lifting ring, an end liner, a feed pipe and a gland bush. The feed port sealing device is characterized in that a sealing flange is arranged on the outer side of the gland bush; a sealing rubber ring is arranged between the gland bush and the sealing flange; a gusset plate is fixedly connected with the outer side of the feed pipe; a screw rod sheathed with a screw nut, a backing plate and a spring passes through the gusset plate to connect the sealing flange, an oil groove is formed on the inner side of the sealing flange, and an oil filler hole is formed on the outer side of the sealing flange. The feed port sealing device can prevent leakage of ore slurry, effectively prevent the ore slurry in an overflow ball mill from flowing back into a mine, remarkably reduce shutdown servicing and failure handling time, and remarkably improve the production efficiency of the ball mill.
Description
Technical field
The utility model belongs to the ball mill technical field, particularly a kind of ball mill charging aperture sealing device.
Background technology
Ball mill, it is a kind of grinding attachment that China is widely used in the ore dressing plant, material and milling medium all are to be fed by charging aperture, enter ball mill barrel inside through giving the ore deposit sleeve, do all body rotation carrying out grinding operations in ball mill barrel, sealing device originally adopts rubber seal to seal, because ball mill is to belong to continuous running operation, the time is long slightly, the rubber seal wear and aging, cause producing the slit between gland and the charging aperture, cause ore pulp to ooze out between the slit.In case occur leaking the ore deposit phenomenon, the fastening method of can only taking to stop is handled, and has influenced the operating efficiency of equipment, and then influences concentrate output.
Summary of the invention
The purpose of this utility model provides a kind of ball mill charging aperture sealing device, effectively the ball mill charging aperture is sealed, and prevents the seepage of ore pulp, reduce to stop handles fault time, for the continous-stable operation of equipment provides assurance.
The purpose of this utility model realizes by following technical proposals:
A kind of ball mill charging aperture sealing device of the present utility model, comprise charging lining, charging end cap, drop handle, aside-liner, feed pipe, gland, it is characterized in that being provided with sealing flange in the described gland outside, O-ring seal is located between described gland and the sealing flange, the described feed pipe outside is fixedly connected with gusset, the screw rod that is with nut, backing plate, spring passes gusset and is connected with sealing flange, and there is oil groove the sealing flange inboard, and there is oil filler point in the outside.
Described gusset is 4-8.
Described oil filler point and oil groove are 4-8 pairs.
The utility model has the advantages that: can prevent the seepage of ore pulp, prevent the generation of the overflowball mill ore pulp phenomenon of falling the ore deposit effectively, reduce the time of parking maintenance and handling failure greatly, can significantly improve the production efficiency of ball mill.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
A kind of ball mill charging aperture sealing device of the present utility model, comprise charging lining 4, charging end cap 3, drop handle 1, aside-liner 2, feed pipe 9, gland 5, it is characterized in that being provided with sealing flange 11 in described gland 5 outsides, O-ring seal 10 is located between described gland 5 and the sealing flange 11, described feed pipe 9 outsides are fixedly connected with gusset 13, the screw rod 14 that is with nut 8, backing plate 12, spring 7 passes gusset 13 and is connected with sealing flange 11, there is oil groove 15 sealing flange 11 inboards, and there is oil filler point 6 in the outside.
Described gusset 13 is 4-8.
Described oil filler point 6 and oil groove 15 are 4-8 pairs.
During making, on ball mill charging lining 4, add gland 5, and it is good with bolting, gland 5 needs retrofit with sealing flange 11 contact-making surfaces, with gusset 13 welding feed pipes 9 outsides, the screw rod 14 that is with nut 8, backing plate 12, spring 7 passes gusset 13 and is connected with sealing flange 11, and O-ring seal 10 is added between gland 5 and the sealing flange 11.After feed pipe 9 and feed leak be connected and fixed, adjust nut 8, backing plate 12 compresses spring 7, and sealing flange 11 and gland 5 are compressed, ore pulp just can not ooze out.
Ball mill was used the glycerine rifle to inject an amount of glycerine by oil filler point 6 to sealing flange 11, and can be guaranteed the sealing of overflowball mill to the ore deposit end in operation process in per about 4 hours.
