Explosion-proof special gas holder

Abstract

The utility model relates to the technical field of industrial gas storage and control equipment, in particular to an explosion-proof special gas holder which comprises a holder body which is of a double-layer explosion-proof structure composed of an outer protection cavity and an inner explosion-proof cavity. A placement mechanism is arranged in the middle of the outer protection cavity, an inner container is arranged below the placement mechanism, and the inner explosion-proof cavity is formed in the inner container; a vertical moving mechanism is arranged between the placing mechanism and the inner explosion-proof cavity, and the top of the cabinet body is integrated with an explosion-proof machine top; the placing mechanism comprises a fixing plate, a first connecting rod, a second connecting rod, a first telescopic cylinder, a placing frame and a limiting rod; two-stage protection is formed through the outer protection cavity and the inner anti-explosion cavity, compared with a traditional single-layer structure, the explosion shock wave peak pressure is greatly reduced, a first telescopic air cylinder of the containing mechanism drives a second connecting rod to drive a containing frame to be pushed outwards, a gas cylinder is stably moved out to an operation area of the outer protection cavity through the containing frame, and the gas cylinder is convenient to assemble, disassemble and replace.
