A kind of preparation technology of 3dff oil tank

Abstract

The invention relates to a 3DFF oil tank and a preparation process thereof. The oil tank comprises a tank body (1); the tank body (1) includes an outer shell (1.1), and an inner shell (1.2) sleeved with the outer shell (1.1); a gap layer (1.3) is formed between the outer shell (1.1) and the inner shell (1.2); a first lining layer (2.1) is arranged on the inner wall of the inner shell (1.2), and is provided with a second lining layer (2.2); an electric conducting layer (3) is arranged on the second lining layer (2.2); a lifting lug (1.4) is inserted in the tank body (1); a connecting block is rotationally positioned on one end, inserted in a cavity of the tank body (1), of the lifting lug (1.4); and a sealing pad is arranged on one surface, contacted with a reinforcing ring (4), of the connecting block. According to the 3DFF oil tank and the preparation process thereof, the oil tank is light in weight, excellent in corrosion resistance and excellent in sealing effect.

Description

technical field [0001] The invention relates to an oil tank, in particular to a double-layer oil tank using 3D material as an interlayer and a production and preparation process of the oil tank, belonging to the technical field of oil tanks. Background technique [0002] At present, the general oil tank adopts a double-layer structure, the inner shell is made of steel, and the outer shell is an insulating and anti-corrosion layer. The two layers are connected and supported by 3D structural materials, and the 3D structural material layer can be Use a leak detector for leak detection; [0003] However, in actual use, it is found that the above-mentioned structure has the following disadvantages: ①Because the material of the inner shell is steel, the entire oil tank is not only heavy, which affects handling and installation, but also has poor corrosion resistance (this is because in In an ultra-low sulfur environment, some microorganisms grow rapidly and produce acetic acid, w...

Problems solved by technology

[0003] However, in actual use, it is found that the above-mentioned structure has the following disadvantages: ①Because the material of the inner shell is steel, the entire oil tank is not only heavy, which affects handling and installation, but also has poor corrosion resistance (this is because in In an ultra-low sulfur environment, some microorganisms grow rapidly and produce acetic acid, which corrodes the steel shell), so the life of conventional steel oil tanks is short; The lifting lugs of the head are directly screwed on the shell, so that oil leakage is prone to occur at the connection part, which affects its use effect and safety performance; ③The connection sealing effect of the head connection is poor, and leakage is easy to occur; therefore, there is an urgent need for a A completely new structure of the oil tank or its preparation process to solve the above defects
