Description

Technical Field

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

[0002] Steel-lined PTFE storage tanks are important storage containers in today's industry. They give full play to the advantages of perfectly combining the high strength and hardness characteristics of steel with the superior physical and chemical properties of PTFE sheets, solving the problem of corrosion resistance of most storage tanks and becoming the mainstay of modern corrosion-resistant containers.

[0003] The prior art discloses a corrosion-resistant steel-lined PTFE storage tank with a publication number of CN220466415U, comprising an inner barrel and an outer barrel, wherein a buffer mechanism is provided between the inner barrel and the outer barrel, wherein the buffer mechanism comprises a mounting ring fixedly mounted on the outer peripheral wall of the inner barrel, wherein four reinforcing rods are fixedly mounted on the outer peripheral wall of the mounting ring, and four buffer rods are fixedly mounted between the four reinforcing rods. The corrosion-resistant steel-lined PTFE storage tank, through the functions of the mounting ring, the reinforcing rods and the buffer rods, not only reinforces the connection between the inner barrel and the outer barrel, but also buffers a certain impact force, thereby reducing the impact of the impact force on the inner barrel. The sponge filling plate is clamped between the inner barrel and the outer barrel, and when subjected to collision and impact, the sponge filling plate will absorb most of the collision and impact force, thereby improving the storage safety of the steel-lined PTFE storage tank.

[0004] The above-mentioned anti-corrosion steel-lined PTFE storage tank improves the corrosion resistance of the steel-lined PTFE storage tank through the effect of the anti-corrosion layer, and then achieves cushioning through the added sponge filling parts. However, the single sponge pad cushioning method will be flattened after long-term use, resulting in a deterioration in the protection effect, and it is easy to be damaged and affect storage. The effect during use is not good, and this needs to be improved. Utility Model Content
