Abstract
The utility model discloses a sealing structure of a wet type ball grinding machine. The sealing structure comprises an end cover and a material inlet lining connected with the end cover, wherein the outer circular surface of the inner end part of the lining is matched with an inner hole of the end cover; the outer circular surface is in clearance fit with the inner hole; the lining is provided with a lining bayonet; the end cover is provided with an end cover bayonet; an axial clearance is formed between the lining bayonet and the end cover bayonet; a sealing ring is arranged in the axial clearance; the surface roughness of the part, matched with the sealing ring, of each of the lining and the end cover is better than the surface roughness of the part, in clearance fit with the sealing ring. The sealing structure of the wet type ball grinding machine is reliable in structural sealing performance, convenient to mount and dismount and long in service life; leakage of slurry can be effectively prevented, and the maintenance cost and the labor intensity are reduced.
Description
Technical field
The utility model relates to ball-grinding machine technical field, relates in particular to the hermetically-sealed construction of the wet ball mill sealing between a kind of end cap and bushing for feeding.
Background technology
Wet ball mill is because grinding machine inside is slurries; so often can be at the local spillage of bushing for feeding afterbody and end cap cooperation; the structure generally adopting in prior art is to seal with 10 × 10 × 13200 asbestos packing; the problem that this hermetically-sealed construction exists is that sealing effectiveness is poor, easily reveal at sealing position; there is the dismounting at sealing position after revealing and change very inconvenience; increase labour intensity and maintenance cost, also affected the production efficiency of ball mill.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of hermetically-sealed construction of wet ball mill is provided; The utility model sealing structure dependable performance, installation, convenient disassembly, long service life, effectively prevents the leakage of slurries, has reduced maintenance cost and labour intensity.
To achieve these goals, the utility model adopts following technical scheme:
A hermetically-sealed construction for wet ball mill, the bushing for feeding that comprises end cap, is connected with end cap, the periphery of described lining inner end coordinates with the endoporus of end cap, and described periphery and endoporus are matched in clearance, form movable sealing.Described lining is provided with lining seam, and end cap is provided with end cap seam, between described lining seam and end cap seam, is provided with end play, between described end play, is provided with sealing ring.
Described matched in clearance is movable sealing.
Described sealing ring is O RunddichtringO.
Described O RunddichtringO is provided with multiple vertically side by side.
The beneficial effects of the utility model:
1. the utility model adopts end cap and lining matched in clearance, forms movable sealing.And easy accessibility, mating surface can not be damaged, when assembling, O RunddichtringO is filled in the gap of end cap and lining successively, play sealing function by axial grip and the close distortion of O type.
2. the utility model has adopted three O RunddichtringOs, and sealing property is better, and its sealing replacement cycle is obviously elongated; install and change easy; ball mill, because the shutdown number of times that spillage problem causes obviously reduces, has improved the production efficiency of ball mill, has reduced maintenance cost and labour intensity.
3. periphery and endoporus are matched in clearance, lining and end cap are being better than the roughness at matched in clearance place with the roughness of sealing ring cooperation place, the machining accuracy and the processing capacity that reduce matched in clearance place, reduce production costs and the amount of labour, ensures that the sealing of sealing ring cooperation position is good simultaneously.
Brief description of the drawings
Fig. 1 is structural representation after the utility model is installed;
Fig. 2 is the partial enlarged drawing at the I place of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As Fig. 1, a kind of hermetically-sealed construction of wet ball mill, comprise end cap, the bushing for feeding 1 being connected with end cap, the periphery 11 of described lining 1 inner end coordinates with the endoporus 31 of end cap 3, described periphery 11 is matched in clearance with endoporus 31, described lining 1 is provided with lining seam 12, end cap is provided with end cap seam 32, between described lining seam 12 and end cap seam 32, be provided with end play 13, between described end play 13, be provided with sealing ring 2, lining 1 and end cap 3 are being better than the roughness at matched in clearance place with the roughness of sealing ring cooperation place, to reduce the machining accuracy at matched in clearance place, reduce production costs and the amount of labour, ensure the sealing of sealing station simultaneously.
Described matched in clearance is movable sealing.
Described sealing ring is O RunddichtringO.
Described O RunddichtringO is provided with multiple side by side.In the present invention, O RunddichtringO is provided with 3 vertically side by side.
Between the flange of lining 1 outer end and the outer face of end cap 3, be provided with sealing gasket, flange is connected by screw 14 with end cap 3.
End cap 3 and lining 1 inner end are matched in clearance, form movable sealing, and easy accessibility, mating surface do not receive damage, in the time that end cap 3 and lining 1 assemble, three O RunddichtringOs are filled in the gap of end cap and lining successively, played sealing function by axial grip and the close distortion of O type.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection domain of the present utility model.
Claims (5)
