Description

Technical Field

[0001] This utility model belongs to the field of flotation machine bolt fixing technology, specifically relating to a screw anti-corrosion device applied to the bottom of a flotation machine. Background Technology

[0002] During the maintenance of the flotation machine, because the flotation machine is immersed in the slurry for a long time, the mineral particles are relatively coarse and the slurry is corrosive, which causes wear and corrosion on the screws. This makes them difficult to disassemble during maintenance, and severe wear can even cause the screws to fall off.

[0003] In view of the above factors, a screw anti-corrosion device is provided for use at the bottom of the flotation machine, which can reduce the corrosion and wear of the screws at the bottom of the flotation tank. Utility Model Content

[0011] The corrosion-resistant fastener is fitted into a recessed positioning hole and engages with the end of the fixing screw.

[0012] Furthermore, the receiving part on the screw positioning seat is inserted into the screw mounting position on the flotation tank body;

[0013] The inner wall of the receiving part is provided with an internal thread that mates with the fixing screw.

[0014] Furthermore, the anti-corrosion fastener includes an outer shell, and an adsorption component is fixedly disposed inside the outer shell. The adsorption component includes a rubber layer and a strong magnet wrapped by the rubber layer.
