Adjustable Dynamic Rotary Separator for Coal Mills

Abstract

The invention relates to a coal powder separator, in particular to an adjustable dynamic rotary separator for a coal mill. The adjustable dynamic rotary separator is characterized in that a distributor is arranged at the lower portion of a driving portion, the interior of the driving portion is connected with a hollow shaft, the lower portion of the distributor is connected with a shell cover plate, the hollow shaft is connected with a guide cone, and moving blades are arranged on the guide cone; a coal dropping pipe is arranged inside the guide cone and connected with a ceramic liner; the upper end of a stationary blade shaft is a hexagonal prism, an elastic cylindrical pin penetrates through the stationary blade shaft and then limits a pointer disc, and the other end of the stationary blade shaft penetrates through a shell cover plate hole and then is fixedly connected through a bolt penetrating through stationary blades. Finer coal powder can be separated out from coal powder through the separator. The separator has the advantages of increasing the capacity of the mill, and improving the coal powder uniformity, thereby improving the boiler combustion efficiency and lowering the unburned carbon in flue dust, and therefore the purposes of improving the coal powder fineness and uniformity indexes, finally improving the boiler combustion efficiency and lowering the unburned carbon in flue dust are achieved.

Description

technical field [0001] The invention relates to a pulverized coal separator, in particular to an adjustable dynamic rotary separator for a coal pulverizer. Background technique [0002] After searching and searching by the National Patent Office, it is found that there is an authorized announcement number CN203875010, which is called a high-efficiency dynamic separator. Its structural characteristics are: static blades and multi-exit distributor structure, which cannot effectively separate coarse and fine powder. . As the fineness of pulverized coal increases, the output of the coal mill decreases, and the rate of decrease in output is far greater than the rate of increase in fineness, and the structure is complex. Contents of the invention [0003] The object of the present invention is to provide an adjustable dynamic rotary separator for coal mills with simple structure, low cost, simple operation and convenient maintenance, which can effectively separate coarse and fi...
