A method for repairing the main shaft of a mixer

Abstract

The invention discloses a method for repairing the main shaft of a mixer, which belongs to the technical field of pellet mixers. The method for repairing the main shaft of the mixer includes the following steps: polishing the part of the main shaft to be repaired to see the light, then cleaning it with a cleaning agent, configuring a repairing agent, adding a reinforcing agent to the repairing agent, and then repairing the main shaft through the repairing agent added with the reinforcing agent. The part to be repaired is laid and filled to form a repaired layer, and the repaired layer is cured. When the curing strength of the repaired layer reaches 80%, the cylinder is sleeved on the repaired layer, so that the cylinder and the unrepaired part of the main shaft form a non-wear There is a gap between the cylinder and the repair layer of the main shaft in the state, and the length of the cylinder is consistent with the length of the part of the main shaft to be repaired. Inject a reinforcing agent into the gap and keep it warm for 24 hours at a temperature of 15-25°C. Hours, the repair is complete. The method for repairing the main shaft of the mixing machine of the invention can quickly repair the worn main shaft of the mixing machine, improve the maintenance efficiency, shorten the maintenance time, and reduce the maintenance cost.

Description

technical field [0001] The invention relates to the technical field of pellet mixers, in particular to a method for repairing the main shaft of a mixer. Background technique [0002] The mixer is an important equipment commonly used in the sintering pellet industry. Its function is to mix different materials evenly for the next process. Whether it can run normally directly affects the stable production of the entire production line. The pellet mixer has been used for more than three years. Due to the wear, erosion and corrosion of materials, the shaft diameter at both ends has changed from 285 mm to 175 mm at one end, and 145 mm at the other end. Continue to use it. Hazard of shaft breakage and production stoppage. [0003] In the existing technology, the hidden dangers of use are eliminated by replacing the worn spindle, and the working performance of the equipment is restored. However, this requires re-ordering the spindle, which requires a long waiting period. The const...
