Abstract
The utility model relates to a rubber gasket for assembling a mill liner. The rubber gasket is a hollow cylindrical rubber gasket of which two ends are thick and the intermediate section is thin, wherein the sections of two hollow thick end sockets are triangular; the two hollow thick end sockets are connected and combined into a whole by a hollow cylinder of which the intermediate section is thin; the two hollow thick end sockets and the hollow cylinder of which the intermediate section is thin share the same smooth inner cylindrical surface, and thus the inserting of bolts is facilitated; during mounting, a bolt head and a nut collar are respectively pressed on the hollow thick end sockets at two ends of the hollow cylindrical rubber gasket; and when the liner is assembled in a mill cylinder, the rubber gasket disclosed by the utility model can play roles of sealing, buffering and protecting.
Description
Technical field
The utility model relates to a kind of rubber gasket, particularly a kind of rubber gasket of assembling lining board of grinder.
Background technology
Grinding machine is the main production equipments to ore deposit rock dust breakdown mill such as mine ore dressing factory, cement plant, and the grinding machine serviceability rate is the key of decision enterprise production continuity, completion production task with the rate of starting.The general volume of grinding machine is big, equipment heavy, the maintenance difficulty, and recondition expense is also bigger.The milling medium of filling is steel ball or rod iron in the grinding machine; Along with the grinding machine rotation produces impact, abrasive action to the ore deposit rock, reach the purpose of comminution of minerals, the while also produces greater impact and wearing and tearing to the protection liner plate of grinding mill barrel and liner; Make lining-plate bolt loosening, cause cylindrical shell to leak the ore deposit; Loosening liner plate and grinding mill barrel produce friction and damage; Loosening simultaneously lining-plate bolt and grinding mill barrel bolt hole form extrusion abrasion; Make bolt hole produce distortion and enlarge, become ellipse or long flat, aggravated liner plate loosening leakage ore deposit and cylindrical shell is produced bigger friction to damage by circle; Serious hourglass goes out ore pulp and gets into drive disk assemblies such as gear, causes that vitals damages, brings out the substantial equipment accident.From taking precautions against, require often to shut down fastening or change bolt, but the equipment that influences starts rate and enterprise production benefit.
Summary of the invention
The technical problem that the utility model will solve provides a kind of rubber gasket of assembling lining board of grinder, is mainly used in mine rod mill, ball mill etc. and the various seal protection that is in the bolted parts of load weight, operating condition difference.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of rubber gasket of assembling lining board of grinder is the hollow cylindrical rubber gasket that two ends are thick, the stage casing is thin; The section of two hollow butt end heads is a triangle, and the thin hollow cylinder in stage casing is combined into one two hollow butt end heads connections.The inner chamber of the hollow cylinder that said two hollow butt end heads and stage casing are thin has same smooth inner cylinder face, is convenient to insert connecting bolt; Connecting bolt head and nut collar thereof are pressed in respectively on the hollow butt end head at hollow cylindrical rubber gasket two ends.The hollow butt end head at two ends is formed inside and outside two cover sealings, has improved leakage performance, and two-sided cushioning effect is played at two of bolt, reduces or avoids bolt looseness; The hollow rubber cylinder has been isolated bolt hole and bolt, can avoid bolt and bolt hole directly to push, rubbing makes bolt hole distortion, thereby causes the loosening and ore pulp of lining board of grinder to leak.
The beneficial effect of the utility model is: grinding machine is played sealing, buffering, three kinds of effects of protection;
1. on sealing property, it is interior anti-changing outer blocking up, and original grinding mill barrel shell that is placed on is pressed outer stifled leak-proof manner by nut, changes into the interior sealing of active and prevents seepage.
2. the hollow butt end head at sealing gasket two plays two-sided cushioning effect to bolt two, reduces or avoids bolt looseness.
3. protection grinding mill barrel and bolt hole can better alleviate milling medium and hit the impulsive force of liner plate to cylindrical shell; The hollow rubber cylinder contains bolt, has isolated bolt hole and bolt, and protection cylindrical shell and lining-plate bolt hole avoid bolt and bolt hole directly to push, rubbing is out of shape bolt hole.Significantly reduce grinding machine and leak the influence to equipment such as ore deposit because of liner plate is loosening, for the equipment dependability of keep the safety in production, carry out production strictly in line with rules and regulations, improve, serviceability rate, prolongation service life of equipment have been created condition, thus the production of promotion enterprise, the raising of economic benefit.
4. the utility model also can be used for other various seal protections that are in the bolted parts of load weight, operating condition difference.

The specific embodiment
Embodiment 1Shown in Fig. 1-3: a kind of rubber gasket of assembling lining board of grinder; The rubber gasket of lining board of grinder is the hollow cylindrical rubber gasket 4 that two ends are thick, the stage casing is thin; The section of two hollow butt end heads 1 is a triangle, and the thin hollow cylinder 2 in stage casing is combined into one two hollow butt end heads 1 connections; Inserting bolt 7 is convenient on the total same smooth face of cylinder 3 of inner chamber of the hollow cylinder 2 that two hollow butt end heads 1 and stage casing are thin.
Embodiment 2As shown in Figure 4: a kind of installation method of rubber gasket of embodiment 1 said assembling lining board of grinder, comprising aligns cooperates the lining board of grinder 5 and grinding mill barrel 6 that processes bolt mounting holes:
[1] lining board of grinder 5 block-by-block handlings is entered predetermined installation site in the grinding mill barrel 6, both bolt mounting holes position alignment; Between the bolt hole of lining board of grinder 5 and grinding mill barrel 6 and the bolt 7, leave the fit clearance that hollow cylindrical rubber gasket 4 is installed; Pack soft hollow cylindrical rubber gasket 4 in the bolt mounting holes of lining board of grinder 5 and the alignment of position, grinding mill barrel 6 hole into, and smooth-going expansion.
[2] from lining board of grinder 5 one sides, bolt 7 is inserted the hollow cylindrical rubber gasket 4 that installs, pass grinding mill barrel 6 backs and install and fastening nut, bolt head and nut collar are pressed in respectively on the hollow butt end head 1 at hollow cylindrical rubber gasket 4 two ends.The hollow butt end head 1 at two ends is formed inside and outside two cover sealings, has improved leakage performance, and two-sided cushioning effect is played at two of bolt 7, reduces or avoids bolt looseness; The hollow rubber cylinder has been isolated bolt hole and bolt 7, can avoid bolt 7 and bolt hole directly to push, rubbing makes the bolt hole distortion, thereby causes the loosening and ore pulp of lining board of grinder 5 to leak.
