At present, the flotation machines used in the beneficiation operation include JJF type flotation machines, KYF type flotation machines, and BF type flotation machines, which are mainly used to remove harmful elements such as fluorine and sulfur in iron ore. After the three-reverse flotation equipment is updated, the lubrication method of the scraper of the flotation machine changes from the original water lubrication to glycerol lubrication, and the post needs to be filled regularly. The existing problems are as follows: the existing filling method is to pick up glycerol with a wooden board and smear it on the shaft bearing, which is inconvenient to operate. In addition, when adding oil, it is necessary to stop the operation of the scraper and exchange for a power-off sign, which takes a long time and has low efficiency. Stopping the scraper also has a certain impact on the flotation operation index, which is not conducive to the stable and smooth progress of the production process.

[0003] In view of the above factors, a lubricating oil adding device for a scraper shaft bearing of a flotation machine is provided, which can effectively improve the operation efficiency of the post. The oil adding time can be reduced by more than two hours, the convenience of operation is improved, the safety risk is reduced, and the influence on the flotation operation caused by stopping the scraper operation for oil injection of the scraper is eliminated.
