Abstract

The invention provides a method for repairing a drive disk of a coal mill and a repair system for the drive disk of a coal mill, and relates to the technical field of repairing a coal mill. The method for repairing the drive disc of the coal mill includes the following repair steps: removing the outer sealing assembly of the coal mill; using a welding torch device to weld and fill the worn grooves on the outer surface of the drive disc in the coal mill to obtain a filled weld pile, and the filled weld pile Protrude the outer circular surface; use a milling device to mill the filler weld deposit until the outer wall surface of the filler weld deposit is consistent with the outer circular surface; reinstall the outer seal assembly. The coal mill drive disc repair system is used for the above-mentioned coal mill drive disc repair method. In the method for repairing the drive plate of the coal mill, the disassembly and assembly process has low requirements on operators, high repair safety, short repair construction period and low consumption of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of coal mill repair, in particular to a coal mill drive disk repair method and a coal mill drive disk repair system. Background technique [0002] Thermal power plants mainly generate electricity by burning coal. Specifically, coal pulverizers are used to grind the coal blocks into pulverized coal, and the pulverized coal is transported to the burner to burn and generate electricity; in the process of grinding the pulverized coal by the coal pulverizer, the obtained pebble coal is processed by pulverized coal. The coal bunker is discharged. However, due to the gap between the stone coal bunker and the drive plate, the stone coal can easily enter the gap and cause wear on the outer surface of the drive plate, forming an irregular annular groove on the outer surface of the drive plate. A corresponding gap is formed between the disc and the sealing assembly, and the coal powder can be directly discharged to the...
