Double-layer oil storage tank

Abstract

The invention discloses a double-layer oil storage tank which comprises a tank body and manholes formed in the circumferential surface of the upper end of the side face of the tank body. The tank body comprises an inner tank part, an outer tank part and a middle layer. The surface of the middle layer is of a convex-concave structure. The middle layer is arranged in the space between the inner tank part and the outer tank part. The double-layer oil storage tank has the beneficial effects that by designing and applying the middle layer with different thicknesses, the volume of the interlayer space can be controllable; the middle layer is good in fitting performance, sealing performance, heat reflection and thermal conductivity, and therefore the situations of temperature rise and uneven temperature distribution caused by thermal radiation of the oil storage tank can be effectively relieved; when oil leaks, the leaked oil can be detected in time, and a detection signal is transmitted to a remote alarm and a remote monitoring station in time, so that measures are taken for preventing excessive leakage of the oil storage tank and reducing losses; the overall structural strength of the outer tank part is high, in this way, the external load of the oil storage tank can be resisted effectively, and stress concentration is avoided.

Description

Technical field [0001] The invention relates to the technical field of liquid storage containers, in particular to a double-layer oil storage tank. Background technique [0002] With the popularization of automobiles in my country, the number of oil storage tanks in industrial and mining enterprises and gas stations is increasing. But at the same time, the leakage problem of oil storage tanks has become more and more common, and double-layer oil storage tanks with an intermediate layer structure have emerged. The double-layer oil storage tank is a double-layer oil tank composed of an inner tank and an outer tank. The tank body is composed of a straight cylinder and hemispherical heads located at both ends of the straight cylinder. There are voids, and materials such as resin are filled in the voids as an intermediate layer. Double-layer oil storage tanks can play a double protective role and can better avoid leakage problems. [0003] The patent number CN201020686208.0 discloses...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the oil tank has no interlayer volume or the interlayer volume is very small, and the interlayer volume of the oil tank cannot be changed. In the event of a tank leakage accident, the alarm cannot be reported in time; the material design of the middle layer is unreasonable, and the sealing of the sandwich structure between the inner tank and the outer tank mainly depends on the resin in the inner and outer tanks, resulting in uneven heating of the tank body and failure Rapid heat conduction, even causing oil tank leakage when the construction process is unstable; the inner wall of the inner shell of the oil tank adopts a reinforced rib structure, which makes the overall structural strength of the oil tank lower and prone to stress concentration
