EXPLOSION-PROOF CHAMBER Russian patent published in 2019 - IPC F42D5/45 F42B39/14 

FIELD: security means.

SUBSTANCE: invention relates to safety during transportation, elimination and experimental development of explosive devices with energy release of up to 70 kg TNTE, which can contain environmentally hazardous highly toxic substances. Explosion-proof chamber comprises a cylindrical housing consisting of a central section and two side sections, the latter being made of two coaxially arranged metal pipes, the space between which in the side sections is filled with foam concrete. Inner pipe of side sections is reinforced from inside with rings and cones, between which ribs are arranged. Two flat two-layer bottoms with loading holes, consisting of inner and outer plates, tightly rigidly connected to each other, having holes for installation of passage elements of operational purpose, covered from inside with armored hoods. Each loading hole with neck is tightly closed from inside with a convex power metal cover, pivotally connected to the bottom plate, in the closed position can be rigidly fixed from the outer side of the plate. Outside loading opening with neck is closed tightly by cover. Antipolisheck protection is made in the form of grid layers and is located on internal cylindrical surface of side sections and convex power metal covers. Longitudinal beam with carriage is installed longitudinally in upper part of chamber cavity. Central section is made of two coaxial metal tubes with a gap. Inner pipe is supported by perforated rings, into which cylindrical insert is rigidly installed, consisting of two coaxially located metal pipes, space between which is filled with concrete. Insert pipes are interconnected by rings. Between internal pipe of central section of housing and cylindrical surface of insert there is a gap, minimum value of which exceeds value of maximum deformation of insert at action of explosive load on it. Inside cylindrical surface of insert is lined with anti-fragmentation protection, made in form of layers of mesh.

EFFECT: design of the explosion-proof chamber of a wide range of applications capable of withstanding the explosion of explosive devices with energy release of up to 70 kg TNTE, which can contain environmentally hazardous highly toxic substances, while ensuring reliable localization of explosion products without ingress of them into the environment in hazardous concentrations.
