DEVICE FOR REWORKING OIL-CONTAINING WASTES (VERSIONS) AND LOADING AND UNLOADING BINS FOR THIS DEVICE Russian patent published in 2004 - IPC

FIELD: reworking of wastes of metallurgical and metalworking processes. SUBSTANCE: proposed device includes hermetic transportation pipe mounted inside furnace at rotation around its axis and connected with drive, as well as loading and unloading bins. Inlet and outlet of said transportation pipe are communicated respectively with loading and unloading bins. Transportation pipe is provided with helical fins in form of separate helical spiral on its inner surface for reciprocating motion of material. Flat fins in form of blades are rigidly mounted between helical fins on inner surface of transportation pipe. Flat surfaces of blades are oriented in way of rotation of transportation pipe for entrapping material during rotation of pipe. Blades are located at angle relative to generatrix of transportation pipe and are inclined towards motion of material. At area of conjugation of blades with inner surface of transportation pipe are deflected from vertical towards tangent in side opposite to direction of rotation of transportation pipe. According to second version, transportation pipe is inclined and translational motion of material is caused by gravitational forces. EFFECT: improved quality of reworking of wastes; simplified construction. 7 cl, 7 dwg 8
