Abstract
A sealing device for a dismounting hole of a mill liner plate comprises a bolt (2), a spacer (3), a gasket (4), a nut (5) and a rubber plug (6), wherein an outer diameter of the rubber plug is smaller than or equal to an inner diameter of the dismounting hole, the rubber plug is arranged in the dismounting hole, and the bolt penetrates through the middle of the rubber plug, a flat head part of the bolt is arranged in the dismounting hole, and a thread part of the bolt is arranged outside the dismounting hole, the spacer and the gasket are sleeved through the thread part of the bolt in sequence, and then the nut is screwed on the thread part of the bolt to make the spacer tightly press the rubber plug. The dismounting hole is arranged on an end cover (7) for dismounting a liner plate (1), when the nut is screwed up, the rubber plug is expanded by a pressure of the spacer and the flat head part of the bolt, and the expanded rubber plug generates an enough frictional force in the dismounting hole to implement a sealing effect, thereby ore pulps can be prevented from being thrown out. The sealing device disclosed by the utility model can be reused, and can reduce an environment pollution of a work site; proved by a practice, the utility model is a reliable sealing device.
Description
Technical field
The utility model technical field of sealing technology, especially a kind of sealing device that is used for the lining board of grinder removal hole.
Background technology
Along with the maximization of grinding machine, be installed on the large-sized grinding mill barrel liner plate or and end cap increasing, more and more heavier, the monolithic weight of some liner plate has reached 1.5 ~ 5 tons, reaches as high as 7.5 tons, thus the dismounting of liner plate assembling become more and more difficult.
In order to solve large-sized grinder liner plate dismounting assembling difficult problem, just the back side end caps of liner plate leaves removal hole at certain faying face place of end cap and liner plate, and end cap or connect with cylindrical shell or be exactly cylindrical shell itself, by this removal hole and by external force liner plate is destroyed, thereby improved the running rate of large-sized grinder with the time that reduces the rebush plate.
Because thereby the existence of removal hole makes ore pulp be thrown out of the outer working site environment that pollutes of cylindrical shell easily.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of sealing device that is used for the lining board of grinder removal hole, the sealing device has excellent sealing effect, and installation and dismounting are all very convenient, and main is can solve ore pulp can not be thrown out of outside the cylindrical shell to improve the working site environment.
For achieving the above object, the utility model adopts following technical scheme:
A kind of sealing device that is used for the lining board of grinder removal hole comprises bolt, pad, packing ring, nut and rubber stopper, the internal diameter of the external diameter≤removal hole of rubber stopper wherein, rubber stopper is placed in the removal hole, run through a bolt at the rubber stopper middle part, the butt end of bolt places in the removal hole, the threaded portion of bolt places outside the removal hole, overlaps Upper gasket and packing ring successively by the threaded portion of bolt, then nut is screwed in the threaded portion of bolt so that pad compresses rubber stopper.
Owing to adopted technical scheme as mentioned above, the utility model produces following good effect:
1, it is rational in infrastructure, simple for sealing device of the present utility model, and the processing buying is convenient, and the installing/dismounting facility is safe and reliable.
2, sealing device of the present utility model can effectively solve ore pulp and is thrown out of outside the cylindrical shell, thereby reduces the contaminated situation of working site environment.
3, sealing device of the present utility model can be reused, and is a kind of reliable sealing device through facts have proved.
Description of drawings
Fig. 1 is a structural profile view of the present utility model.
Among Fig. 1: the 1-liner plate; The 2-bolt; The 3-pad; The 4-packing ring; The 5-nut; The 6-rubber stopper; The 7-end cap.
The specific embodiment
The lining board of grinder removal hole as shown in Figure 1, though be referred to as liner plate 1 removal hole, this removal hole be arranged on the end cap 7 or be arranged on the cylindrical shell quantity of this removal hole more than one but several.Sealing device of the present utility model is used on this removal hole.
In conjunction with Fig. 1, the sealing device that the utility model is used for the lining board of grinder removal hole comprises bolt 2, pad 3, packing ring 4, nut 5 and rubber stopper 6.
The internal diameter of the external diameter≤removal hole of rubber stopper 6, in other words the external diameter of rubber stopper 6 is more smaller than the internal diameter of removal hole, rubber stopper 6 is placed in the removal hole, run through a bolt 2 at rubber stopper 6 middle parts, the butt end of bolt 2 places in the removal hole, the threaded portion of bolt 2 places outside the removal hole, overlaps Upper gasket 3 and packing ring 4 successively by the threaded portion of bolt 2, then nut 5 is screwed in the threaded portion of bolt 2 so that pad 3 compresses rubber stopper 6.
During installation bolt 2 packed in the rubber stopper 6, the rubber stopper 6 that bolt 2 will be housed is then packed in the removal hole, adds pad 3, packing ring 4 and nut 5 and gets final product according to certain moment fastening nut 5.When fastening nut 5, by the pressure of pad 3 and bolt 2 butt ends rubber stopper 6 is swollen, the rubber stopper 6 that swells produces enough frictional force in removal hole, thereby plays sealing function, prevents that ore pulp is thrown out of.
When unclamping nut 5, the frictional force between rubber stopper 6 and the removal hole disappears, and whole sealing device can be taken out.
Because bolt 2 has butt end, so tighten and when unclamping nut 5, bolt 2 can not spin.
Sealing device of the present utility model can be reused, and is a kind of reliable sealing device through facts have proved, reduces the contaminated situation of working site environment.
Claims (1)
1. sealing device that is used for the lining board of grinder removal hole, the sealing device comprises bolt (2), pad (3), packing ring (4), nut (5) and rubber stopper (6), it is characterized in that: the internal diameter of the external diameter≤removal hole of rubber stopper (6), rubber (6) is plugged in removal hole, run through a bolt (2) at rubber stopper (6) middle part, the butt end of bolt (2) places in the removal hole, the threaded portion of bolt (2) places outside the removal hole, overlap Upper gasket (3) and packing ring (4) successively by the threaded portion of bolt (2), then nut (5) is screwed in the threaded portion of bolt (2) so that pad (3) compresses rubber stopper (6).
