Pressure relief type explosion-proof tank

Abstract

The invention discloses a pressure relief type explosion-proof tank, which comprises a tank body and a tank bottom, wherein a cover plate with cover plate pressure relief holes is arranged on the top of the tank body; the tank body consists of an inner cylinder and an outer cylinder; the outer cylinder consists of an outer cylinder wall and an outer cylinder buffer layer arranged in the outer cylinder wall; the tank bottom is provided with an outer cylinder wall bottom plate; a buffering base plate is arranged on the upper part of the outer cylinder wall bottom plate, on the inner side of the outer cylinder buffer layer and on the lower part of the inner cylinder; outer cylinder wall pressure relief holes are formed on the outer cylinder wall bottom plate; the inner cylinder consists of an inner cylinder wall and an inner cylinder buffer layer in the inner cylinder wall; a buffering lining plate is arranged on the lower part of the cover plate and on an inner side of the inner cylinder buffer layer; the buffering lining plate and the buffering base plate are made of porous foam metals; the inner cylinder buffer layer and the outer cylinder buffer layer are made of closed pore foam metals; and the thickness of the buffering base plate is greater than that of the buffering lining plate. By the explosion-proof tank, fragments produced through explosion can be prevented from flying out of the tank so as not to damage surrounding equipment and crowd, the internal pressure of the tank body can be reduced through pressure relief, and the safety performance of the explosion-proof tank is improved.

Description

technical field [0001] The invention relates to a metal explosion-proof tank, in particular to a pressure relief type explosion-proof tank. Background technique [0002] The existing metal explosion-proof tank has the problem of bulky structure and lack of flexibility, which limits its application range. The Chinese utility model patent ZL200920033823.9 discloses a weak explosion-proof tank with a foam metal sandwich. The inner and outer panels of the tank body The space is filled with metal foam to solve the problem of bulky structure of the existing explosion-proof tank, but the explosion-proof tank disclosed in the utility model patent has no cover plate, and debris such as metal fragments generated by the explosion will damage surrounding equipment and people. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a pressure relief explosion-proof tank, which can not ...
