Abstract
The utility model discloses a slurry-leakage-prevention ball mill which comprises a material intake end and a material discharge end; the material intake end or the material discharge end comprises a material intake and discharge bush (1) and a material intake and discharge end cover hollow shaft (3) sleeved in the bush; a linkage screw (2) is linked with the material intake and discharge end cover hollow shaft (3) and the material intake and discharge bush (1); and a tight contact part is arranged in front and back of the material intake and discharge end cover hollow shaft (3) and the material intake and discharge bush (1) respectively. The slurry-leakage-prevention ball mill provided by the utility model has the beneficial effects that suspension can not be generated, alternating bending moment in circulation and reciprocating is prevented for a linkage bolt, and a conical surface is in 'moving fit' without a clearance; the slurry-leakage-prevention ball mill has good and reliable seal performance, is convenient to mount and dismount, effectively prevents the phenomena of slurry leakage and bolt breaking, and protects and prolongs the service life of a plurality of main key components of the ball mill.
Description
Technical field
The utility model relates to ball mill, relates in particular to input and output material lining and the junction sealing of input and output material end cap quill shaft of ball mill.
Background technology
Ball mill is widely used in the ore dressing plant, cement plant in mine etc. need to be to the enterprise of ore deposit rock dust breakdown mill, and ball mill serviceability rate and the rate of starting are to determine enterprise's continuous production, complete one of key of production task.The general volume of ball mill is large, equipment heavy, the maintenance difficulty, and recondition expense is larger.Due to rotatablely moving of ball mill, make various molecules very even to the cutting grinding of mating surface, the water in ore pulp is transported the good various molecules of cutting grinding timely.Again and again, in cylindrical shell, the cut grinding in the gap of mating surface is increasing, cause at last the input and output material lining to be in vacant state, be suspended on the flange of input and output material end cap quill shaft, attachment bolt is pulled on distortion and is even ruptured under the effect of the alternation moment of flexure that moves in circles, make connecting flange lose airtight effect, passage is thoroughly opened, and the spillage phenomenon produces thereupon.The ore pulp that spills not only has a strong impact on the board health, more brings Safety production questions.
The utility model content
The purpose of this utility model is the problem that solves ball mill leakage slurry, and a kind of mortar leakage prevention ball mill is provided.
For achieving the above object, the mortar leakage prevention ball mill that the utility model provides, comprise feed end and discharge end, feed end or discharge end comprise the input and output material lining and are sleeved on the interior input and output material end cap quill shaft of lining, connect screw joints input and output material end cap quill shaft and input and output material lining, be respectively equipped with close contact section before and after input and output material end cap quill shaft and input and output material lining, it is characterized in that the close contact section of described input and output material lining and input and output material end cap quill shaft is that taper seat contacts.
" fiting property " of the conical surface is strong, can not produce suspension, so just makes attachment bolt avoid the alternation moment of flexure that moves in circles, and still " movingly " of band gap not of the conical surface, good seal performance and reliably, dismounting is very convenient.
The beneficial effect that the utility model adopts is: adopted that spillage and Broken bolt phenomenon have obtained eradicating thoroughly after this structure.Some crucial critical pieces to ball mill have played the effect that protection is lengthened the life; promote the production of security civilization, improved the platform effect of ball mill and the stability of ore-dressing technique index, alleviated maintenance personal's labour intensity; reduce the consumption of the energy and spare part, promoted the economic benefit of enterprise.
Description of drawings
Fig. 1 is the utility model mortar leakage prevention feeding of ball mill end schematic diagram.
Fig. 2 is the utility model mortar leakage prevention discharging end of ball mill schematic diagram
Shown in figure: 1. input and output material lining, 2. attachment bolt, 3. input and output material end cap quill shaft.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, the present embodiment mortar leakage prevention ball mill, it comprises feed end input and output material lining 1 and is sleeved on the interior input and output material end cap quill shaft 3 of lining, connect screw 2 and connect input and output material end cap quill shaft 3 and input and output material lining 1, input and output material end cap quill shaft 3 and input and output material lining 1 front and back are respectively equipped with close contact section, and the close contact section of input and output material lining and input and output material end cap quill shaft is that taper seat contacts.After adopting this structure, " fiting property " that can bring into play the conical surface is strong, can not produce suspension, so just make attachment bolt avoid the alternation moment of flexure that moves in circles, and still " movingly " of band gap not of the conical surface, good seal performance and reliable, dismounting is very convenient.
As shown in Figure 2, discharge end is also done same improvement, plays same effect.
