Description
Technical Field
The utility model relates to a high pressure grinding roller field, specific high pressure grinding roller roll surface subdivision structure that says so.
Background
With the wide application of the high-pressure roller mill in various fields, the problems of abrasion of the roller surface of the high-pressure roller mill and the increase of the maintenance cost caused by the replacement of the wear-resistant roller body are gradually valued by people. The roller surface of the existing high-pressure roller mill is made of materials with higher hardness in order to ensure the service life of the roller surface, the material characteristics and the structural shape of the roller surface are determined, and the roller surface has the defects of higher production and processing cost, low material utilization rate, incapability of being installed by using larger interference when the roller surface is installed, easy generation of cracks and even breakage after the edge of a key groove is stressed and the like. And the production and manufacturing period of the whole roll surface is longer, and spare parts occupy more funds. The field replacement is also complicated and the downtime is long.
The utility model discloses a novel high pressure roller mill roll surface subdivision structure just can be fine this problem of solution, and the better wear-resisting steel sheet of wear resistance can be selected to the subdivision roll surface that mentions here as first-selected material, and its material stable in structure is convenient for process, and material utilization is high. The split structure of the roll surface is more convenient for independent replacement of parts with serious abrasion after the roll surface is abraded, and the split roll surface has the characteristics of simple processing, short manufacturing period, convenience in field assembly and disassembly and the like.
Disclosure of Invention
The utility model aims at providing a high pressure roller mill roll surface subdivision structure has solved that the production and processing cost is higher, material utilization is low, the roll surface can not use great magnitude of interference to install when the installation, produce defects such as crackle or fracture easily even behind the edge department atress of keyway.
The utility model adopts the technical proposal that: the utility model provides a high pressure roller mill roll surface subdivision structure, it is including flower type axle and subdivision roll surface, its technical essential is: the pattern shaft is provided with a slide rail along the axial direction, the surface of the split roller is provided with a groove corresponding to the slide rail on the pattern shaft, the slide rail is of a dovetail structure, the dovetail slide rail is tightly attached to the groove on the surface of the split roller, and the surface of the split roller is arranged outside the pattern shaft through the slide rail and is fixedly connected with the pattern shaft through a pressing plate and a bolt.
The utility model has the advantages and beneficial effects that: the method has the advantages of shortening the processing period of the wear-resistant roller body of the high-pressure roller mill, reducing the processing cost, shortening the replacement time and reducing the use cost of a user on the premise of being equivalent to the service life of the roller body of the existing high-pressure roller mill.

the drawings illustrate the following: 1. The method comprises the following steps of (1) a pattern shaft, 2, a split roller surface, 3, a pressing plate, 4 and bolts.
The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, but the following examples are merely illustrative of the present invention and do not represent the scope of the present invention as defined in the claims.
Detailed Description
Shown by figure 1, figure 2, figure 3, figure 4, the utility model relates to a high pressure roller mill roll surface subdivision structure, it is including flower type axle 1 and subdivision roll surface 2, wherein: the pattern shaft is provided with a slide rail along the axial direction, the surface of the split roller is provided with a groove corresponding to the slide rail on the pattern shaft, the slide rail is of a dovetail structure, the dovetail slide rail is tightly attached to the groove on the surface of the split roller, and the surface of the split roller is arranged outside the pattern shaft through the slide rail and is fixedly connected with the bolt 4 through the pressing plate 3.
Furthermore, the number of the slide rails arranged on the flower-shaped shaft is one.
Further, the slide rails arranged on the patterned shaft can be uniformly or non-uniformly arranged in the circumferential direction of the shaft.
Furthermore, the slide rail arranged on the patterned shaft can be directly machined on the shaft or can be installed after parts are machined.
Furthermore, the surface of the split roller is made of wear-resistant materials, such as wear-resistant steel plates and wear-resistant cast iron.
Further, the split roller surfaces can be divided into a plurality of blocks according to the angle and the number of the slide rails arranged on the pattern shaft, wherein each split roller surface is independent.
Furthermore, each pressure plate is fixed with a split roller surface through four bolts.
The first embodiment is as follows: in the present embodiment, six dovetail-shaped slide rails are uniformly arranged on the patterned shaft 1 along the circumferential direction of the shaft along the axial direction. On the outside of the pattern shaft 1, the roll surface is set to six split roll surfaces 2 which are split evenly, depending on the position of the slide rail. The surface 2 of the splitting roller is provided with a groove corresponding to the upper sliding rail of the patterned shaft 1. The dovetail-shaped slide rail is tightly attached to the groove of the split roller surface 2, so that the split roller surface 2 is prevented from displacement when the flower-shaped shaft 1 rotates.
When the split roller type roller mill is installed, the plurality of split roller surfaces 2 are installed outside the patterned shaft 1 according to the width of the roller surface of the high-pressure roller mill, and the split roller surfaces are tightly pressed by the pressing plate 3 and the bolts 4, so that the installation can be completed. In the use process, if one or more independent split roller surfaces 2 are abraded greatly, only the pressing plate 3 and the bolts 4 need to be detached, and the new split roller surfaces 2 can be replaced.
One or more split roller surfaces are arranged on the split roller surface according to the width of the roller surface of the high-pressure roller mill, and after the split roller surface is installed, the end surface is pressed by a pressing plate. The split roller surfaces can be divided into a plurality of parts according to the angles and the number of the sliding rails arranged on the patterned shaft, wherein each split roller surface is independent, and when one or more split roller surfaces are abraded, the split roller surfaces can be independently replaced.
