US12455152 - Intrinsic-safety explosive disposal and protection device and using method therefor

An intrinsic-safety explosive disposal and protection device is incapable of causing secondary damage itself during excessive explosion or extreme conditions and capable of realizing efficient absorption for energy from explosion shock waves. The device includes an explosion-proof top cover, a support plate, an explosion-proof material filling layer and an explosion-proof drum; the explosion-proof drum is of a drum body structure having openings in two ends; the explosion-proof top cover is disposed on a top opening of the explosion-proof drum; the support plate is supported inside the explosion-proof drum, a height of the support plate in the explosion-proof drum is adjustable, and an area located below the support plate in the explosion-proof drum is a placing area for the explosive. An explosion-proof material is filled between the support plate in the explosion-proof drum and the explosion-proof top cover to form the filling layer. Use of the device is also provided.
