Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a novel plastic-lined anti-corrosion tank. Background Art

[0002] A storage tank is a tank used to store materials. Conventional storage tanks do not have an inner lining. When corrosive materials are stored, the materials will corrode the inside of the tank, reducing the service life of the tank.

[0003] The existing anti-corrosion lining pasted inside the storage tank can effectively prevent the corrosion of corrosive materials to the storage tank and increase the service life of the storage tank. The anti-corrosion lining installed by pasting cannot work well after the anti-corrosion lining has been used for a period of time. When the anti-corrosion lining needs to be replaced, it is inconvenient to replace it. In addition, due to the lack of a sealing structure in the connection between the storage tank and the upper cover, foreign matter can easily enter the steel storage tank body and affect the material in the steel storage tank. In view of the above problems, the inventor proposes a new type of plastic-lined anti-corrosion tank to solve the above problems. Utility Model Content
