Adjustable spiral blanking device for vertical mill

Abstract

The invention provides an adjustable spiral blanking device for a vertical mill. The adjustable spiral blanking device comprises an blanking tube and also comprises a guide pipe, wherein a lower connecting flange is arranged at the upper end of the guide pipe, a plurality of long arc-shaped holes are formed in the lower connecting flange, an upper connecting flange is arranged at the bottom end ofthe blanking tube, and the lower connecting flange and the upper connecting flange are fixedly connected through bolts penetrating through the long arc-shaped holes; a spiral guide plate is arrangedon the inner side wall of the guide pipe, and the spiral guide plate extends into the lower end of the inner part from the upper end of the inner part of the guide pipe. The adjustable spiral blankingdevice provided by the invention solves the material deviation problem of the blanking device as a result of flushing, the single-sided wear of the blanking device is reduced, the nonuniformity of wear of a polishing roller is reduced, the service life of the blanking device is prolonged, and the reliability of the vertical mill is improved and the operating stability of the vertical mill is improved. Meanwhile, the guide pipe can be adjusted rotatably, and the mounting angle of the guide pipe can be adjusted rotatably through the long holes of the connecting flanges according to the actual operation and wear conditions of the vertical mill, so that the optimum using effect is obtained, and the adjustable spiral blanking device is simple and convenient to use.

Description

technical field [0001] The invention relates to the technical field of grinding equipment, in particular to an adjustable screw feeding device for a vertical mill. Background technique [0002] As a main grinding equipment, the vertical mill has been widely used in grinding raw materials, cement, coal powder, slag and steel slag. [0003] The lower part of the existing vertical mill blanking device is a circular tube made of wear-resistant material, and the material is sent into the blanking tube through elevators, feeding belts and other equipment, and then enters the vertical mill for grinding. When the feeding belt feeding is not aligned with the vertical mill feeding tube, the material will be unevenly distributed on the grinding table, which will cause uneven wear of the grinding rollers on the grinding table and increase the maintenance cost of the vertical mill. In addition, when the vertical mill is designed as a combination of inclined pipe and vertical pipe for fe...
