Description
Technical Field
The utility model relates to the technical field of grinding rollers of coal mills, in particular to a long-service-life grinding roller seat lining plate.
Background
The bowl-type medium speed coal mill can be divided into four parts from bottom to top along the height direction: the device comprises a driving device, a grinding part, a drying and separating space and a coal dust separating and distributing device; the working process is as follows: the grinding disc or the grinding ring is driven by a motor to rotate through a speed reducing device and a vertically arranged main shaft; raw coal enters the surfaces of two groups of grinding pieces which move relatively through a coal dropping pipe, is extruded and ground under the action of a compacting force, and is crushed into coal dust.
In the prior art, the grinding roller seat lining plate of the coal mill consists of a protection plate made of Q255 and an installation connection plate in a welded mode, and has the advantages of poor wear resistance, short service life, frequent replacement of worn grinding roller seat lining plates, low running efficiency of the coal mill, unreasonable installation mode, great influence on safe running of the coal mill, frequent replacement, large workload and high maintenance cost.
Disclosure of Invention
The utility model aims to provide a long-service-life grinding roller seat lining plate, which is convenient to install and is wear-resistant.
The technical aim of the utility model is realized by the following technical scheme: the utility model provides a high life grinds roller seat welt, includes grinds roller seat welt, grinds semicircular tubular structure of roller seat welt, grinds the top of roller seat welt evenly to be provided with a plurality of perpendicular to grinds the connecting plate of roller seat welt inside wall, the lateral wall of grinding roller seat welt is multistage sandwich structure.
The setting through adopting the connecting plate can be more convenient when the installation, need not dismantle too much coal pulverizer part just can change the grinding roller seat lining board, and the connecting plate that perpendicular grinding roller seat lining board set up can make the laminating need the guard surface of protection after the installation of grinding roller seat lining board.
The utility model is further provided with: the lining plate of the grinding roller seat is of a multi-layer sandwich structure and comprises a wear-resistant layer, a filling layer and an inner lining layer from outside to inside.
The wear resistance can be timely improved by adopting the multi-layer sandwich structure.
The utility model is further provided with: the surface hardness of the wear layer should be greater than 58HRC.
The use of a predetermined Rockwell hardness of the wear layer ensures that the service time of each grinding roller base liner is approximately the same.
The utility model is further provided with: the wear-resistant layer is a composite steel plate.
The cost can be reduced by adopting the arrangement of the clad steel plates.
The utility model is further provided with: the filling layer is powdery filler.
In order to better protect the machine body, the operator can be better reminded of the damage point of the roller seat lining plate by adopting the setting of the filling layer.
The utility model is further provided with: the protection angle of the grinding roller seat lining plate is 180 degrees.
The protection surface of the traditional grinding roller seat lining plate is too small, and the protection of the traditional grinding roller seat lining plate can be more uniform by adopting 180-degree large-range protection.
In summary, the utility model has the following beneficial effects: the setting through adopting the connecting plate can be more convenient when the installation, need not dismantle too much coal pulverizer part just can change the grinding roller seat lining board, and the connecting plate that perpendicular grinding roller seat lining board set up can make the laminating need the guard surface of protection after the installation of grinding roller seat lining board.

Detailed Description
The utility model is described in further detail below with reference to fig. 1-3.
Examples
In the prior art, the grinding roller seat lining plate of the coal mill consists of a protection plate made of Q255 and an installation connection plate in a welded mode, and has the advantages of poor wear resistance, short service life, frequent replacement of worn grinding roller seat lining plates, low running efficiency of the coal mill, unreasonable installation mode, great influence on safe running of the coal mill, frequent replacement, large workload and high maintenance cost.
After installation, the protection effect on the grinding roller seat is poor because the installation angle of the lining plate is unreasonable.
As shown in fig. 1 and 2, the long-service-life grinding roller seat lining plate comprises a grinding roller seat lining plate 1 and a grinding roller seat lining plate 1, wherein the grinding roller seat lining plate 1 mainly protects one side of a grinding roller seat, which is easy to grind, and reduces production abrasion cost.
In order to be more attached to the outer structure of the grinding roller seat, the whole grinding roller seat lining plate 1 is of a semicircular tubular structure.
In order to enable the installation angle between the grinding roller seat lining plate 1 and the grinding roller seat to be more attached after installation, the top of the grinding roller seat lining plate 1 is uniformly provided with a plurality of connecting plates 2 perpendicular to the inner side wall of the grinding roller seat lining plate 1, so that the grinding roller seat lining plate 1 can be fixed after installation to form a parallel or flat attaching effect with the grinding roller seat.
As preferable: in order to ensure that the situation of edge tilting and the like of partial instruments can occur during installation, the inner side angle of the connecting plate 2 and the grinding roller seat lining plate 1 is an acute angle, so that the grinding roller seat lining plate 1 can be ensured to be clung to a grinding roller seat after being fixed so as to achieve a good protection effect.
As preferable: in order to ensure that a user can be reminded when the grinding roller seat lining plate 1 is worn to a safety line, the grinding roller seat lining plate 1 is of a multi-layer sandwich structure and comprises a wear-resistant layer 3, a filling layer and an inner liner layer from outside to inside.
The wear-resistant layer 3 and the inner liner may be made of a composite material, for example: clad steel plates, clad metal materials, and the like.
In order to ensure weather resistance in the use process, the surface hardness of the wear-resistant layer 3 should be greater than or equal to 58HRC, and the roller seat lining plate 1 can be ensured not to be replaced too frequently in the use process after the arrangement.
As preferable: in order to remind the filling user that the lining plate is used at the position of the safety line, the filling layer is powdery filling, and when the lining plate is worn excessively, the user can intuitively see the wearing condition.
The protection angle of the grinding roller seat lining plate 1 is 180 DEG
The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
