Description
Technical Field
The utility model relates to a grinding roller technical field especially relates to a coal pulverizer's exempting from to add hot type grinding roller device.
Background
The grinding roller is used as a key part of the vertical mill, and because the components of the material to be milled are complex and often contain some hard impurities, such as stones, iron blocks and the like, the grinding roller is easy to cause serious abrasion in the long-term milling process; at present, grinding roller and grinding roller seat adopt interference fit's mode to carry out fixed connection usually among the grinding roller device of domestic medium speed coal pulverizer, and the grinding roller structure of this kind of connected mode need adopt the heating form when the dismouting, not only leads to the fact the grinding roller to warp easily, influences the organizational performance on grinding roller wear-resisting alloy layer, and the dismouting in-process technical degree of difficulty is great moreover, dismouting inefficiency.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defect of difficult disassembly and assembly in the prior art and providing a heating-free grinding roller device of a coal mill.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the heating-free grinding roller device of the coal grinding machine comprises a grinding roller mounting seat, a grinding roller is mounted on the extension of the grinding roller mounting seat, a plurality of front limiting bolts are mounted on the front side of the grinding roller mounting seat in a threaded manner, the front limiting bolts are uniformly distributed around the grinding roller mounting seat, the front limiting bolts penetrate through the grinding roller mounting seat and are in threaded connection with the grinding roller, a plurality of rear limiting bolts are mounted on the rear side of the grinding roller mounting seat in a threaded manner, the rear limiting bolts are uniformly distributed around the grinding roller mounting seat, and the rear limiting bolts penetrate through the grinding roller mounting seat and are in threaded connection with the grinding roller; the center position of grinding roller mount pad is seted up the centre bore, the inboard fixed mounting of centre bore has the positioning disk.
Preferably, the front limit bolts and the rear limit bolts have the same shape and structure, and the number of the front limit bolts and the number of the rear limit bolts are the same.
The utility model provides a pair of coal pulverizer exempt from to add hot type grinding roller device, beneficial effect lies in: the grinding roller and the grinding roller mounting seat are fixed through the front limiting bolt and the rear limiting bolt, when the grinding roller and the grinding roller mounting seat are mounted and dismounted, the grinding roller and the grinding roller mounting seat can be dismounted only by tightly rotating or loosening the front limiting bolt and the rear limiting bolt, the operation is simple, and the practicability is high
