Description

Technical Field

[0001] The utility model belongs to the technical field of mobile docking of polytetrafluoroethylene storage tanks, in particular to an end docking mechanism of a steel-lined polytetrafluoroethylene storage tank. Background Art

[0002] A storage tank is a tank used to store various chemical substances. However, some chemical substances are highly corrosive and will corrode the inner wall of the tank, which will not only pollute the stored chemical substances but also reduce the service life of the tank. People can effectively solve the above problems by adding corrosion-resistant PTFE plate lining to the inner wall of the tank.

[0003] Most of the existing PTFE storage tank docking uses a sling to lift a part of the PTFE storage tank for mobile docking. The lifting process with the sling will cause shaking, and the docking position needs to be constantly adjusted during the docking process, which increases the difficulty of the work and wastes a lot of time. There are also certain safety hazards in the process of lifting and moving with the sling. Utility Model Content
