DEVICE FOR REACTIVE CERAMIC AND CONCRETE BLOCKS PRESSING Russian patent published in 2006 - IPC B28B3/00 

FIELD: building, particularly production hollow ceramic and concrete blocks by pressing operation with the use of reactive jet.

SUBSTANCE: device comprises cylindrical vertical body, feeding bunker connected to cylindrical body top, transversal hollow beams having gas cavities in upper beam parts and air cavities in lower beam parts. Void formers are suspended to beams. Air pipes are inserted in void former cavities and in body wall cavities. Gas pipes communicated with gas collectors extend along axes thereof. Vertical air and gas channels are formed in body walls and in void formers. The channels are communicated with body and void formed cavities and with collector. Upper channel parts are connected with rounded cavities provided with nozzles. The nozzles extend downwards at acute angles to combustion chamber axis. Cavities formed by body walls and void formers define combustion chamber, which has grid shape in plane. Upper part of the combustion chamber communicates with feeding bunker provided with lattice metering valve. Lower part of the combustion chamber comprises exhaust nozzle having baffle plate for gas suspended to the exhaust nozzles. Vibrators and vertical lifting means are connected to body walls.

EFFECT: extended technological capabilities and reduced costs of block production.
