Abstract

The invention provides a coal mill driving disc repairing method and a coal mill driving disc repairing system, and relates to the technical field of coal mill repairing. The coal mill driving disc repairing method comprises the following repairing steps of dismounting an outer sealing component of a coal mill; using a welding gun device to weld and fill an abrasion groove in the outer circle faceof a driving disc in the coal mill to obtain a filling welding pile, wherein the filling welding pile protrudes out of the outer circle face; milling the filling welding pile by using a milling device until the outer wall surface of the filling welding pile is consistent with the outer circular surface; and reassembling the outer sealing component. The coal mill driving disc repairing system is used for carrying out the coal mill driving disc repairing method. According to the coal mill driving disc repairing method, the requirement for operators in the disassembling and assembling process islow, repairing safety is high, the repairing construction period is short, and manpower and material resource consumption is low.

Description

technical field [0001] The invention relates to the technical field of coal mill repair, in particular to a method for repairing a coal mill drive disc and a coal mill drive disc repair system. Background technique [0002] Thermal power plants mainly use coal to generate electricity. Specifically, coal pulverizers need to be used to grind coal into pulverized coal, and the pulverized coal is transported to the burner for combustion to generate electricity. However, due to the gap between the coal bunker and the transmission disk, the stone coal can easily enter the gap and cause wear on the outer surface of the transmission disk, forming irregular annular grooves on the outer surface of the transmission disk. A gap is correspondingly formed between the disc and the sealing assembly, through which the pulverized coal can be directly discharged to the outside, causing pollution to the workshop environment. [0003] In the prior art, after the transmission disc is worn out, t...
