Description
Technical field
The utility model relates to a kind of grinding roller dust guard.
Background technology
Coal pulverizer is by coal crusher and wears into the machinery of coal dust, and it is the important auxiliary equipment of coal-powder boiler, and at key positions such as its grinding rollers, bearing must, at high dust pollution, ensure under the adverse circumstances of the lack of lubrication that high temperature low speed causes to run.In this case, the performance of bearing and stability just concern the stable operation of whole equipment.Extend bearing service life to greatest extent, also just mean the power generating ratio time, thus improve equipment job performance, the waste in the manpower avoiding unnecessary maintenance down to bring and material resources.Grinding roller position entirety is positioned at coal pulverizer chamber, in working order surround by high temperature coal dust.Pulverized coal particle is very thin, if the sealing of grinding roller is slightly abnormal, very easily enters into bearing grinding roller by bad sealing inner.Existing sealing is gluey air bag dust seal, and because grinding roller work can produce very high temperature, temperature can change or destroy the shape of air bag, dust is caused to fall in bearing, tie down bearing, so air bag needs change once half a day, cause the increase of cost.Due to Roller of Coal Grinder many employings flooding system lubrication, lubricating oil just changes once a period of time.Once coal dust enters grinding roller inside, grinding roller inside will be rested within a very long time, become the abrasive particle raceway of bearing and rolling element being caused to additional wear.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and provide a kind of simple and ingenious structure, good dustproof effect, the dust-proof time is long, and repair and replacement number of times is few, and cost of investment is low, decreases a kind of grinding roller dust guard that labour drops into.
The purpose of this utility model is achieved through the following technical solutions: a kind of grinding roller dust guard, comprise grinding roller, base and axis, base is provided with axis, and axis break-through grinding roller is connected with base, axis is provided with dust cover, dust cover inwall is provided with the first dividing plate, bearing is provided with between grinding roller and axis, grinding roller is provided with dust-proof clamping plate, dust-proof clamping plate are provided with second partition, and second partition is arranged on below dust cover, graphite packing is provided with between first dividing plate and second partition, grinding roller bottom is provided with two annular locating nub, base top is provided with two ring-type detents, and annular locating nub is placed in ring-type detent just.
Further improvement of the utility model is: axis maintains static, and grinding roller is moved by bearing and annular locating nub.
Further improvement of the utility model is: two ring-type detents have the same center of circle.
The utility model compared with prior art has the following advantages:
This vibrational power flow is simply ingenious, owing to using graphite packing, there is seal lubrication effect, can not because of the high temperature produced in plant equipment production process rapid deformation, maintenance time can from before within one day, become two weeks maintain and replace once, and good seal performance, cost of investment is low, maintenance labour less investment, good dustproof effect, the dust-proof time is elongated.
accompanying drawing illustrates:
Fig. 1 is elevational schematic view of the present utility model;
Fig. 2 is base plane schematic diagram of the present utility model;
Number in the figure: 1-grinding roller, 2-axis, 3-dust cover, 4-first dividing plate, 5-bearing, the dust-proof clamping plate of 6-, 7-second partition, 8-graphite packing, 9-base, 10-annular locating nub, 11-ring-type detent.
detailed description of the invention:
in order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 and Fig. 2 shows a kind of embodiment of a kind of grinding roller of the utility model dust guard, described a kind of grinding roller dust guard comprises grinding roller 1, base 9 and axis 2, base 9 is provided with axis 2, and axis 2 break-through grinding roller 1 is connected with base 9, axis 2 is provided with dust cover 3, dust cover 3 inwall is provided with the first dividing plate 4, bearing 5 is provided with between grinding roller 1 and axis 2, grinding roller 1 is provided with dust-proof clamping plate 6, dust-proof clamping plate 6 are provided with second partition 7, and second partition 7 is arranged on below dust cover 3, graphite packing 8 is provided with between first dividing plate 4 and second partition 7, grinding roller 1 bottom is provided with two annular locating nub 10, base 9 top is provided with two ring-type detents 11, and annular locating nub 10 is placed in ring-type detent 11 just, axis 2 maintains static, grinding roller 1 is moved by bearing 5 and annular locating nub 10, article two, ring-type detent 11 has the same center of circle, this vibrational power flow is simply ingenious, good dustproof effect.
Owing to being provided with graphite packing 8 between the first dividing plate 4 and second partition 7, graphite packing 8 good airproof performance, also there is lubricity simultaneously, can not produce because of plant equipment the high temperature caused and cause distortion, thus avoid dust and drop in bearing 5, avoid the damage of bearing 5, thus improve production efficiency.
Because graphite packing 8 in use can tail off, so need two weeks to change once, the air bag adopted before comparing is changed once half a day, and cost of investment reduces, and maintain and replace labour reduces.
