LINE FOR MAKING BRICKS Russian patent published in 1994 - IPC

FIELD: brick pressing. SUBSTANCE: line has a hopper, mounted on a frame, and a press-mold, having thrust wall; end wall, movable relative to the thrust wall and a punch, and lateral walls, mounted with possibility of displacement in a horizontal plane relative to the end wall in opposite directions and with possibility of engagement with this wall. The end wall has pins, normally secured to it and arranged in holes of eyelets of the punch; replaceable limiters are arranged in holes of the frame rests. Springs are mounted on the pins between the limiters and the eyelets. The punch, connected with the movable end wall, is arranged in guides for horizontal motion. The end wall and the thrust wall are provided by flexible blinds. Between the hopper and the press mold a gate valve with drive unit is mounted; a shutter with drive unit is mounted between the press-mold and a mechanism for discharging pressed bricks. The shutter has a traverse bar. A conveyer has endless belts, embracing guiding pulleys, between which a descendible platform is mounted. A mechanism for drawing apart the lateral walls is in the form of wedges with tie rods, which may move relative the traverse bar with the aid of springs, set on the tie rods. The frame has mutually normal guiding grooves; the lateral walls have carriers and holes; the carriers are placed in the guiding grooves, and the wedges are placed in the holes and in the guiding grooves. Firing furnace is joined by a plate-like conveyer with the above mentioned conveyer. The pulleys and drums for the endless belt are mounted on a common shaft; transporting surfaces of the endless belt conveyer and of the plate-type conveyer are placed on the same level in a horizontal plane at a place of their joining together. Clay mixer with the hopper is connected with a rotary drying chamber with the aid of an intermediate chamber, containing a member for loosening the clay. The clay mixer and the rotary drying chamber are mounted with inclination over the firing furnace. A ventilator for supplying heat transfer agent into the rotary drying chamber, connected with an exhaust pipe of the firing furnace, is mounted at side of the clay disintegrator. EFFECT: enhanced quality of bricks. 12 cl, 10 dwg
