Abstract
The utility model discloses a medium speed pulverizer grinding roller protector, including setting up the skeleton oil blanket lag on the skeleton oil blanket of grinding roller and setting up in the sealing ring lag in the grinding roller sealing ring and the roller support sealing ring outside. Compared with the prior art, the utility model the advantage lie in: the improved medium-speed coal mill has the advantages that the improved medium-speed coal mill is improved in original design, low in improvement cost, capable of being manufactured by utilizing waste pipes and plates, simple to implement, short in construction period, free of any influence and side effect on operation of the coal mill, capable of prolonging service lives of a sealing ring of the grinding roller and a framework oil seal, reducing consumption of spare parts and fault frequency of the coal mill, simultaneously capable of reducing consumption of lubricating oil and common electricity rate, and capable of saving a large amount of economic cost.
Description
Technical Field
The utility model relates to a coal pulverizer protection technical field specifically indicates a medium speed coal pulverizer grinding roller protector.
Background
The grinding roller sealing form of the medium-speed coal mill is that the framework oil seal is sealed, the outer side of the medium-speed coal mill is provided with a grinding roller sealing ring and a roller support sealing ring, the grinding roller sealing ring and the roller support sealing ring are in lap joint (1mm clearance) to form a sealing cavity, and sealing air is introduced into the grinding roller sealing ring and plays a role in protecting the framework oil seal by isolating air-powder mixture. Because the grinding roller sealing ring and the framework sealing ring are washed by the air-powder mixture and the sealing air for a long time, the sealing ring is seriously blown and damaged, the gap is enlarged, the sealing air fails, and further the direct particles of the air-powder mixture are in contact with the framework oil seal to damage the framework oil seal, so that the lubricating oil fails, the grinding roller bearing is locked, if the roller sleeve cannot be found in time, the roller sleeve is cracked, and the overhaul period is long.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem mentioned in the background art, providing a medium speed pulverizer grinding roller protector.
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a medium speed pulverizer grinding roller protector, is including setting up the skeleton oil blanket lag on the skeleton oil blanket of grinding roller and setting up in the sealing ring lag in the grinding roller sealing ring and the roller support sealing ring outside.
As a preferred scheme, the framework oil seal protective sleeve is a waste pipe or a waste plate.
As a preferred scheme, the sealing ring protecting sleeve is a waste pipe or a waste plate.
Compared with the prior art, the utility model the advantage lie in: the improved medium-speed coal mill has the advantages that the improved medium-speed coal mill is improved in original design, low in improvement cost, capable of being manufactured by utilizing waste pipes and plates, simple to implement, short in construction period, free of any influence and side effect on operation of the coal mill, capable of prolonging service lives of a sealing ring of the grinding roller and a framework oil seal, reducing consumption of spare parts and fault frequency of the coal mill, simultaneously capable of reducing consumption of lubricating oil and common electricity rate, and capable of saving a large amount of economic cost.
Drawings
Fig. 1 is the utility model relates to a medium speed pulverizer grinding roller protector's schematic structure diagram.
As shown in the figure: 1. framework oil seal, 2, framework oil seal lag, 3, grinding roller sealing ring, 4, roller support sealing ring, 5, sealing ring lag, 6, grinding roller, 7, grinding roller support.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Example 1
With reference to the attached drawing 1, the grinding roller protection device for the medium-speed coal mill comprises a framework oil seal protection sleeve 2 arranged on a framework oil seal 1 of a grinding roller 6 and a sealing ring protection sleeve 5 arranged on the outer sides of a grinding roller sealing ring 3 and a roller support sealing ring 4.
The framework oil seal protective sleeve 2 is a waste pipe.
The sealing ring protecting sleeve 5 is a waste pipe.
Example 2
With reference to the attached drawing 1, the grinding roller protection device for the medium-speed coal mill comprises a framework oil seal protection sleeve 2 arranged on a framework oil seal 1 of a grinding roller 6 and a sealing ring protection sleeve 5 arranged on the outer sides of a grinding roller sealing ring 3 and a roller support sealing ring 4.

Example 3
With reference to the attached drawing 1, the grinding roller protection device for the medium-speed coal mill comprises a framework oil seal protection sleeve 2 arranged on a framework oil seal 1 of a grinding roller 6 and a sealing ring protection sleeve 5 arranged on the outer sides of a grinding roller sealing ring 3 and a roller support sealing ring 4.
The framework oil seal protective sleeve 2 is a waste pipe.
The sealing ring protecting sleeve 5 is made of waste plates.
Example 4
With reference to the attached drawing 1, the grinding roller protection device for the medium-speed coal mill comprises a framework oil seal protection sleeve 2 arranged on a framework oil seal 1 of a grinding roller 6 and a sealing ring protection sleeve 5 arranged on the outer sides of a grinding roller sealing ring 3 and a roller support sealing ring 4.
The framework oil seal protective sleeve 2 is made of waste plates.
The sealing ring protecting sleeve 5 is a waste pipe.
The design that this scheme was mainly made according to the long period operation of coal pulverizer to each spare part of grinding roller erode a series of serious problems that produce, its original design is not comprehensive enough, long-term to aspects such as grinding roller spare part wearing and tearing, spare part consumption and maintenance. According to the scheme, the framework oil seal protective sleeve 2 is arranged on the framework oil seal 1 of the grinding roller 6, so that the framework oil seal can be effectively prevented from being directly washed away by the air-powder mixture when the blowing clearance between the grinding roller sealing ring 3 and the roller bracket sealing ring 4 is enlarged; set up sealing ring lag 5 to the grinding roller sealing ring 3 and the 4 outsides of roller support sealing ring, prevent that the wind powder mixture from directly scouring away grinding roller sealing ring 3 and roller support sealing ring 4, extension grinding roller sealing ring 3 and roller support sealing ring 4 life and operating duration.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
