Manufacturing process for high-strength double-layer oil storage tank

Abstract

The invention discloses a manufacturing process for a high-strength double-layer oil storage tank. The process comprises the steps of preparing of an inner tank body and two seal heads, splicing, preparing of a middle layer and preparing of an outer-layer tank body and tank mouth hole accessories; and an inner-layer tank body and the two seal heads are manufactured through dies, and are spliced toform the inner tank body, and then the steps of preparing of the middle layer, preparing and bonding of reinforcing ribs and preparing of the outer-layer tank body and the tank mouth hole accessoriesare carried out to obtain the double-layer oil storage tank. The oil storage tank is made of high-strength glass fiber reinforced plastic, and a glass fiber material is arranged between an outer structure layer and an inner structure layer of a tank body wall. According to the process, an anti-impact plate is arranged on the inner surface of a tank body, so that the inner wall of the storage tankis not prone to damage; the plurality of reinforcing ribs are arranged in the oil storage tank body, so that the pressure-bearing capacity of the tank body is greatly improved, and the storage tank is not prone to deformation when being used for a long time after being buried; the seal heads of the tank body adopt two split seal head body structures, so that the pressure bearing capacity of the oil tank is further improved, the evaporation loss of an oil liquid can be effectively reduced, and the leakage of the oil liquid is prevented; and according to the high-strength double-layer oil storage tank, the sealing effect is good, the service life is long, and the safety is higher.

Description

technical field [0001] The invention relates to the technical field of oil storage tanks, in particular to a manufacturing process of a high-strength double-layer oil storage tank. Background technique [0002] At present, the oil storage tanks used in gas stations are generally double-layer oil storage tanks. The double-layer oil tanks are usually composed of inner steel plates and outer high-strength, corrosion-resistant glass fiber shells. Their service life is that of ordinary single-layer oil tanks. 5-10 times of that, it can be used safely for 30 years. This type of double-layer oil tank can also be used in chemical industry, printing and dyeing, ink and other industries to store liquid materials. [0003] Existing double-layer oil tanks are usually buried underground, and the tank body is easily deformed after long-term use, especially in the middle section of the tank body, which may cause leakage of the tank body, which may cause environmental pollution or endanger...

AI Technical Summary

Problems solved by technology

The pressure bearing capacity of the existing oil tank head is often not ideal, resulting in poor sealing of the head, which is also easy to cause oil leakage and evaporation, reducing the safety and storage capacity of the double-layer oil storage tank
