Non-central blanking type solid shaft transmission pulverized coal separator and use method

Abstract

The invention discloses a non-central blanking solid shaft transmission pulverized coal separator and a using method, the non-central blanking solid shaft transmission pulverized coal separator comprises a solid shaft transmission device, an upper shell and a lower shell, and the solid shaft transmission device is arranged on the upper shell; the upper side part of the solid shaft transmission device is arranged above the upper shell; the lower side part of the solid shaft transmission device is arranged in the upper shell; the upper shell and the lower shell can be tightly butted and fixedly connected; a rotor is arranged below the solid shaft transmission device; and static blades are arranged on the outer side of the rotor. The structure is simple, and sealing is reliable. For a dynamic separator matched with non-central blanking powder manufacturing equipment, hollow shaft transmission is simplified into solid shaft transmission, so that the transmission structure is simplified, the number of parts is reduced, and the production cost is reduced; all parts of the separator are designed in a modularized mode, installation and maintenance are convenient, the solid shaft transmission separator is small in occupied space, powder pipe butt joint in a transformation project is simple, the workload is small, the bearing sealing mode is reliable, and the sealing air demand quantity is small.

Description

technical field [0001] The invention belongs to the technical field of pulverized coal separation, and in particular relates to a non-center-blanking solid-shaft driven pulverized coal separator and a use method thereof. Background technique [0002] At present, in the application of electric power, steel, cement and other industries, the common coal mills have the following types: steel ball mills, which are low-speed coal mills, such as MTZ, etc.; double-inlet and double-outlet steel ball mills, which are low-speed coal mills Coal mills such as BBD, etc.; bowl-type coal mills, which are medium-speed coal mills, such as RP, HP, etc.; wheel-type coal mills, which are medium-speed coal mills, such as ZGM, MPS, MBF, etc.; ball ring mills The coal machine is a medium-speed coal mill, such as ZQM, etc.; the medium-speed coal mill is basically a central drop, and raw coal and other materials are dropped from the coal drop pipe in the center of the separator into the grinding area...

AI Technical Summary

Problems solved by technology

The central hollow shaft takes up a lot of space, which leads to an increase in the pitch circle of the powder outlet. It is difficult to connect the powder outlet pipe in the renovation project. The corners or elbows formed by the powder pipe are easily worn and increase the flow resistance of the air powder.
