Buried glass fiber reinforced plastic double-wall oil storage tank monitored through liquid medium and preparing method of buried glass fiber reinforced plastic double-wall oil storage tank

Abstract

The invention discloses a preparing method of the buried glass fiber reinforced plastic double-wall oil storage tank monitored through a liquid medium. The glass fiber reinforced plastic double-wall oil storage tank comprises an inner tank body (1), an outer tank body (2) and a hollow layer (3). Three-dimensional hollow fabric is adhered to the outer wall of the inner tank body (1) and the inner wall of the outer tank body (2), so that the hollow layer (3) is formed. A solid reinforced rib (4), a water storage tank (5) communicated with the hollow layer (3), an inlet (6) and a lug (7) are arranged on the outer wall of the outer tank body (2). According to the buried glass fiber reinforced plastic double-wall oil storage tank, tensile modulus and mechanical strength are high, corrosion resistant performance and seepage resistant performance are good, petroleum products can be monitored online in real time, safety performance is high, weight is light and service life is long. The preparing method of the buried glass fiber reinforced plastic double-wall oil storage tank is reasonable in technology design and strong in maneuverability. Compared with the prior art of a female die and injection forming technology, the preparing method of the buried glass fiber reinforced plastic double-wall oil storage tank can greatly improve structure strength of a tank body, reduce device investment and raw material cost, save labor and improve production efficiency.

Description

technical field [0001] The invention relates to an oil storage tank, in particular to a buried FRP double-wall oil storage tank which is used in a gas station and is monitored by a liquid medium, and a preparation method thereof. Background technique [0002] With the rapid development of my country's automobile industry, the number of automobile gas stations is increasing day by day. In my country, oil storage tanks in gas stations generally adopt horizontal steel structures. Due to the influence of surrounding humid environment, stray current, oil erosion and other factors, the tank body is easily corroded. Corrosion not only greatly shortens the service life of the storage tank, but more seriously, it may cause the leakage of refined oil. Once refined oil leaks, it will not only cause serious pollution to the soil and groundwater resources that human beings depend on for survival, but also seriously threaten human health. [0003] The use of FRP double-wall oil storage ...

AI Technical Summary

Problems solved by technology

[0004] At present, the preparation process of FRP double-wall oil storage tanks is mainly made by the process of female mold and injection molding. Not only the equipment investment is large, the preparation process is complicated, a large number of workers are required, and the preparation efficiency is very low. Moreover, because the reinforcement material is chopped fiber, The tensile modulus and mechanical strength of the product are low, and the strength of the tank needs to be increased by increasing the wall thickness, resulting in increased material consumption and high cost
