Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bearing seats, and in particular relates to a sand prevention mechanism for a bearing seat of a shot blasting elevator. Background Art
[0002] When the PAA line (shot blasting line) is in production, the lifting motor needs to keep running to transport the steel sand from the bottom to the top of the blasting head. The lifting belt in the lifting bin is fixed on the lifting shaft, and the two sides of the shaft are bearing seats. The inside of the bearing seat is exposed to the bin filled with steel sand. Due to the gap between the bearing installation and operation inside the bearing seat, over time, the steel sand will enter the bearing and wear the bearing. When the bearing seat is worn and cannot rotate normally, it begins to rub against the installed shaft. Eventually, the bearing seat and the shaft are all worn, causing long-term equipment downtime and waste of replacement costs. Therefore, a sand prevention mechanism for the bearing seat of a shot blasting elevator is proposed. Summary of the invention
