GRAVITY SPEEDBRAKE FOR FALLING SOLID DOMESTIC WASTE IN REFUSE CHUTE OF HIGH-RISE BUILDING Russian patent published in 2004 - IPC

FIELD: municipal engineering. SUBSTANCE: speed-brake is arranged along refuse chute well axis and formed as diaphragm rotatably attached to axles. Speed-brake has counterweights. Refuse chute well comprises loading flaps. Speed-brake has rectangular body with inner dimension equal to refuse chute well diameter. Diaphragm axles are located in body depressions. Diaphragms are identical to each other and displaced from one another along body height. Each diaphragm is made as row of spaced apart conical corrugated fingers. Length of each finger is less than refuse chute well radius. Lower part of hollow body connected with refuse chute well has conical inserts. EFFECT: possibility of chute adaptability to high-rise building, increased operational efficiency, possibility of cleaning device usage, noise reduction, simplified construction, improved working capacity. 4 cl, 5 dwg
