Abstract

The utility model relates to a grinding-roll sealing device, which is arranged at a grinding-roll bearing side, the grinding-roll bearing side is provided with sealing rings. The sealing rings comprise three sealing rings, the first sealing ring is arranged at middle; and the second sealing ring is arranged at right of the first sealing ring, that is, near to the grinding-roll bearing; the third sealing ring is arranged at left of the first sealing ring, that is, far away from the grinding-roll bearing. The grinding-roll sealing device is applied to grinding-roll sealing of the vertical roller mill; adoption of the grinding-roll sealing device improves sealing capacity of the grinding-roll, and improves grinding efficiency of the vertical roller mill, frequent shutdown processing caused by frequent replacement of the sealing ring due to wear and tear is avoided, and the service life of the machine set is extended, operation rate of the machine set is increased.

Description

The grinding roller sealing device
Technical field
The utility model relates to vertical roll grinder, particularly a kind of grinding roller sealing device in the vertical roll grinder.
Background technology
Grinding roller is housed in the vertical roll grinder, and vertical roll grinder is used for rolling pulverizing by abrasive material.
The following structure of the general employing of grinding roller sealing device in the at present domestic and international vertical roll grinder: in grinding roller bearing side two sealing rings are installed,, are prevented oil leak so that grinding roller bearing side is sealed.
The shortcoming of said structure is that leakage efficiency is low; because dust is big in the vertical roll grinder; first sealing ring is worn very soon; when first ring wear when can't stop dust; dust invades second sealing ring; second sealing ring begins to be worn, and when causing leakage of oil until the sealing of second sealing ring is inoperative, this just shuts down and handles.
The utility model content
Task of the present utility model provides a kind of improved grinding roller sealing device, and it has solved the low problem of existing grinding roller sealing device leakage efficiency.
Technical solution of the present utility model is as follows:
A kind of grinding roller sealing device, it is installed in grinding roller bearing side, in grinding roller bearing side sealing ring is housed, described sealing ring is three sealing rings, first sealing ring is placed in the centre position, and second sealing ring is placed in the right side of first sealing ring, promptly is adjacent to the grinding roller bearing, the 3rd sealing ring is placed in the left side of first sealing ring, promptly is away from the grinding roller bearing.
The installation direction of described first sealing ring and second sealing ring is for installing in the same way.
The installation direction of described the 3rd sealing ring and first sealing ring is oppositely to install.
Described the 3rd sealing ring is made by the high material of anti-wear performance.
Grinding roller sealing device of the present utility model is applicable to the grinding roller sealing of vertical roll grinder.Adopt grinding roller sealing device of the present utility model, improved the grinding roller sealability, improved the mill efficiency of vertical roll grinder simultaneously; avoided needing frequent replacing after being worn because of sealing ring; cause regular shutdown to be handled, prolonged unit service life, improved the unit operation rate.
Description of drawings
Accompanying drawing is the structural representation of a kind of grinding roller sealing device of the present utility model.
Number in the figure:
1 is first sealing ring, and 2 is second sealing ring, and 3 is the 3rd sealing ring, and 4 is the grinding roller bearing.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Referring to accompanying drawing, a kind of grinding roller sealing device of the present utility model is installed in grinding roller bearing 4 sides, in grinding roller bearing 4 sides several sealing rings is housed.
Specifically, these sealing rings are three sealing rings, and it is to lay like this that these three sealing rings are positioned at grinding roller bearing 4 sides:
First sealing ring 1 is placed in the centre position; Second sealing ring 2 is placed in the right side of first sealing ring 1, promptly is adjacent to grinding roller bearing 4; The 3rd sealing ring 3 is placed in the left side of first sealing ring 1, promptly is away from grinding roller bearing 4, and is just far away slightly apart from grinding roller bearing 4.
As shown in FIG., the installation direction of first sealing ring 1 and second sealing ring 2 is for installing in the same way.The installation direction of the 3rd sealing ring 3 and first sealing ring 1 is oppositely to install, and promptly installs " back-to-back ".
The 3rd sealing ring 3 is to be made by anti-wear performance height and long material of life-span.
Grinding roller sealing device of the present utility model adopts three sealing rings that the grinding roller bearing is sealed, and has improved the grinding roller sealing means thus, has improved the grinding roller sealability.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
