DEVICE FOR HEATING MATERIALS Russian patent published in 1994 - IPC

FIELD: transport. SUBSTANCE: device has gantry frame, induction heater, mechanism for moving induction heater and movable heating modules. Gantry frame is attached to the base. Frame of induction heater has П-shaped design and is formed by horizontal and two vertical sections. Any section has magnetic circuit, frame and winding. Any movable heating module is formed by frame, attached to the frame of magnetic circuit and electromagnetic screen. Electromagnetic screens are fixed onto vertical sections of frame of induction heater. Frames of movable modules are disposed symmetrically about longitudinal axis of frame of induction heater. Any module is kinematically connected with base and is mounted for rotation in vertical surface and fixation in end positions. Windings of vertical sections of induction heater are connected one to another in parallel, they are connected in series with winding of horizontal section of the heater. Magnetic circuit and electromagnetic screen of any movable module are mounted for interaction (with one its end) with lower edge of magnetic circuit and electromagnetic screen of corresponding vertical section of heater. EFFECT: improved efficiency of operation. 12 cl, 6 dwg
