ANTI-EXPLOSION PANEL WITH ADDITIONAL DAMPER Russian patent published in 2018 - IPC E04B1/92 

FIELD: methods of explosion protection.

SUBSTANCE: invention relates to protective devices used in explosive and radioactive facilities, such as easy detachable panels and roofs, blast guards and shields, pressure relief valves. Anti-explosion panel with an additional damper contains a metal armored frame with a metal armored shell and a filler-lead, has four fixed pipe-supports in the ends, and in the cover of the explosive object, four supporting rods are rigidly fixed, which are telescopically inserted into the fixed pipe-supports of the panel and are provided with sheet stops arranged in the upper part, and the filler is made in the form of a spherical or arbitrary shape of crumbs of different diameters, and for fixing the limit position of the panel to the ends of the supporting elastic rods with stop sheets, a damping element is attached to damping the impact loads of the panel against the stop sheets, and it is attached oppositely to the panel and is directed to its side and is made in the form of a three-dimensional body with an internal cavity and surfaces equidistant to the surfaces of the panel, while its internal cavity is filled with an air-lead disperse system, the lead being made in the form of a crumb of a spherical shape, and between the damping element, attached oppositely to the panel, and a metal frame with armored metal skin on the support rods are installed bushings from a rapidly disintegrating material, for example, glass of the "triplex" type. To the damping element opposite panel, on the side of the metal frame, an additional damper is attached, made in the form of a conical rubber-cord elastic shell filled with polyurethane.

EFFECT: higher reliability of explosion-resistant device operation during emergency explosion at the facility, and ensured return of these device to the original position after explosion.
