Problems solved by technology

However, buried oil storage tanks also have many defects. The tank body is prone to corrosion if it is buried underground for a long time. The premise is that there must be a safe distance for placing oil storage tanks on the ground. For gas stations in cities, such a safe distance is usually not available, so that the corroded oil storage tanks cannot be successfully removed from the ground. get up

Embodiment Construction

[0024] See figure 1 , a modified buried oil storage tank, has a steel tank body 1, the inner wall of the tank body 1 is provided with a bottom layer 2 formed by laminating fiber cloth and spraying resin and solidified at the same time, and an intermediate layer 3 is arranged on the inner wall of the bottom layer 2 , the middle layer 3 is a three-dimensional spaced one-piece fabric woven with glass fiber as a whole, which is a hollow structure formed by resin compounding. The inner wall of the middle layer 3 is provided with a surface layer 4 which is formed by laminating fiber cloth and spraying resin at the same time. The surface layer 4 A surface protection layer 5 made of electrostatic resin is provided on the inner wall of the body. Wherein, the middle layer 3 is connected with a leak-proof detection system, and the leak-proof detection system includes two conduits drawn from the middle layer 3, an inflation valve 6 installed on one of the conduits and used to fill the mid...

Abstract

The invention provides a transformed buried oil storage tank and a transforming method thereof. The oil storage tank is provided with a steel tank body. A bottom layer, which is formed by laminating fiber cloth, spraying resin and curing the resin, is arranged on the inner wall of the tank body. A middle layer is arranged on the inner wall of the bottom layer. The middle layer adopts a hollow structure, which is formed by compounding 3-D spacer fabrics, woven integrally from glass fiber, through resin. The surface layer, which is formed by laminating fiber cloth, spraying resin, and curing the resin, is arranged on the inner wall of the middle layer. The surface protection layer made of electrostatic resin is arranged on the inner wall of the surface layer. The transforming method comprises the following specific steps of S1, clearing the oil storage tank; S2, spraying bonding resin; S3, preparing the bottom layer of the oil storage tank; S4, preparing the middle layer of the oil storage tank; S5, preparing the surface layer of the oil storage tank; S6, preparing the protection layer on the surface of the oil storage tank; and S7, mounting a leakage detection system. The oil storage tank has high corrosion resistance and wear resistance, and the service life is long; and the transforming method is simple and flexible, and the service life of the oil storage tank is prolonged.

Description

technical field [0001] The invention relates to the technical field of oil chemical containers, in particular to a modified buried oil storage tank and a modified method thereof. Background technique [0002] At present, the storage tanks in most gas stations are buried. Because they are buried underground, they have the characteristics of not occupying the surface area and good explosion-proof effects. However, buried oil storage tanks also have many defects. The tank body is prone to corrosion if it is buried underground for a long time. The premise is that there must be a safe distance for placing oil storage tanks on the ground. For gas stations in cities, such a safe distance is usually not available, so that the corroded oil storage tanks cannot be successfully removed from the ground. get up. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, provide a modified ...
