Problems solved by technology

[0002] Existing oil storage tanks generally adopt a double-layer arrangement of an outer shell and an inner shell, wherein the outer shell is made of glass fiber reinforced plastic, and the inner shell is made of steel, so that the inner shell has a reinforced support, while the outer shell has an insulating effect. However, because the inner shell is made of steel, its weight is greatly increased, which affects handling and installation, and its corrosion resistance is poor and its life is short
[0003] At the same time, there is a gap between the outer shell and the inner shell in the oil storage tank to detect whether there is any liquid leakage in the inner shell, but this gap makes the outer shell and the inner shell not connected, affecting both The strength between, that is, it is easy to deform the outer shell or the inner shell, and its leak detection is not accurate

Embodiment Construction

[0021] Examples, see e.g. Figures 1 to 3 As shown, a double-layer FRP oil storage tank 3DFF tank structure includes a tank body 1, the tank body 1 includes an outer shell 11 and an inner shell 12, the inner shell 12 is placed in the outer shell 11, and the inner shell 12 A flexible conductive layer 2 is fixed on the inner wall of the inner casing 12, and a reinforcing rib structure is fixed on the inner wall of the inner casing 12. There is a gap cavity between the outer casing 11 and the inner casing 12, and a gap layer 13 is provided in the gap cavity.

[0022] The outer casing 11 has a first through hole 111 and a second through hole 112, and the inner casing 12 has a first manhole 121 and a second manhole 122, and the first manhole 121 and the second manhole 122 extend respectively. Out of the first through hole 111 and the second through hole 112 , a detection tube 14 is connected to the outer casing 11 , and the detection tube 14 communicates with the gap cavity.

Abstract

The invention discloses a 3DFF tank structure used for a double-layer oil storage tank made by glass fiber reinforced plastics. The 3DFF tank structure comprises a tank body (1) including an outer shell (11) and an inner shell (12). The inner shell (12) is put inside of the outer shell (11). The 3DFF tank structure is characterized in that a flexible conductive layer (2) is fixed on an inner wall of the inner shell (12); a reinforced rib structure is further fixed on the inner wall of the inner shell (12); and a clearance cavity is arranged between the outer shell (11) and the inner shell (12) and provided with a clearance layer (13). The a 3DFF tank structure used for a double-layer oil storage tank made by glass fiber reinforced plastics is simple in structure, low in weight, high in strength, fine in corrosion resistance, stable in structure and long in service lifetime.

Description

Technical field: [0001] The invention relates to the technical field of oil storage tanks, in particular to a 3DFF tank structure of a double-layer glass fiber reinforced plastic oil storage tank. Background technique: [0002] Existing oil storage tanks generally adopt a double-layer arrangement of an outer shell and an inner shell, wherein the outer shell is made of glass fiber reinforced plastic, and the inner shell is made of steel, so that the inner shell has a reinforced support, while the outer shell has an insulating effect. However, since the inner shell is made of steel, its weight is greatly increased, which affects handling and installation, and its corrosion resistance is poor and its life is short. [0003] At the same time, there is a gap between the outer shell and the inner shell in the oil storage tank to detect whether there is any liquid leakage in the inner shell, but this gap makes the outer shell and the inner shell not connected, affecting both The s...
