METHOD AND DEVICE FOR SEPARATION OF FIBROUS INCLUSIONS FROM PRODUCTS OF MILLING OF WORN-OUT TIRES Russian patent published in 2003 - IPC

FIELD: processing of depreciated mechanical rubber goods, in particular, conveyer belts and the most large-capacity type of mechanical rubber goods-worn-out automobile tires. SUBSTANCE: separation of fibrous inclusions from rubber-textile mixes is accomplished on a sectional concave with sieves of 3.8 mm and 1.25 mm, installed at an angle to the horizon for oscillatory motions with an amplitude of 1-6 mm and frequency of 1500-3000 l/s and under action of an ascending air stream for extraction of textile fiber. The mix is delivered by a layer of 1 to 15 mm thick. The stage of sieving os preceded by the stage of sintering of textile fiber to the size of sinters exceeding the dimensions of the sieve hole, in the section of sintering in the form of a continuous surface, before the upper sieve positioned directly under the loading pipe connection. The device for producing the ascending air stream consists of an intake hood positioned past the area of sieving below along the concave, and intake windows with an adjustable section area, made in the form of holes in the side walls of the sections under the section of fiber sintering. The extent of the section of sieving of the first sieve as 1 to 4. EFFECT: enhanced quality of separation of the rubber-textile mix. 8 cl, 1 dwg
