Glass fiber reinforced plastic double-deck oil tank and manufacture technology thereof

Abstract

The invention relates to a glass fiber reinforced plastic double-deck oil tank which comprises an oil tank main body, a leakage detector and a transportation and installation annular support structure, wherein an oil inlet is formed in the top of the oil tank main body; the oil tank main body comprises a steel tank body at the inner layer, the steel tank body comprises a middle steel plate, side steel plates and a seal steel plate, and the middle steel plate, side steel plates and seal steel plate are fixedly connected for forming a closed cavity; a middle interlayer is covered at the periphery of the steel tank body, a glass fiber reinforced plastic outsourcing layer is arranged at the periphery of the middle interlayer, and the glass fiber reinforced plastic outsourcing layer comprises a first RTM region, a second RTM region, a third RTM region, a fourth RTM region and a fifth RTM region. The steel tank body adopts socket type, overlap joint type for connecting tank body steel plates, double-deck welding ensures connection reliability and airtightness, and the operation is convenient and fast; a vacuum pressure detection method is sensitive and timely; the glass fiber reinforced plastic outsourcing layer adopts RTM manufacture technology, the strengthening rib is integrated with the tank body for avoiding bubble residue of outer shell of the tank body and ensuring structure strength and stability.

Description

technical field [0001] The invention relates to a container for storing and transporting articles or materials, in particular to a glass fiber reinforced plastic double-layer oil tank and its manufacturing process. Background technique [0002] At present, single-layer iron storage tanks are widely used in chemical, printing and dyeing, ink, gas stations and other underground storage tanks. When single-layer iron storage tanks store chemical solvents, petroleum and other flammable, explosive or toxic substances, due to Hazardous chemicals and toxic substances have factors such as physical corrosion and electrolytic corrosion. Ordinary single-layer iron oil tanks leak after being corroded. Once leakage occurs, it will bring serious consequences of environmental pollution or underground water resources. Moreover, since the single-layer iron oil tank is buried underground all the year round and is corroded by groundwater and electrolytic corrosion, the quality and service life ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a glass fiber reinforced plastic double-layer oil tank, which solves the problems of the existing double-layer oil tank that inner reinforcement needs to be carried out in a limited space, interlayer detection is not sensitive enough, the outer tank has many bubbles, and is not beautiful enough
