DEVICE FOR HEATING INSPISSATED AND SOLIDIFIED OIL PRODUCTS IN TANK CARS Russian patent published in 2004 - IPC

FIELD: emptying railway tank cars holding inspissated and solidified viscous oil products. SUBSTANCE: device that can be used for emptying tank cars at washing-and-steaming stations, thermal power stations, and other enterprises where tank cars holding mentioned materials are to be emptied has microwave module as well as rigidly coupled to the latter transmitting line incorporating straight waveguide and waveguide bend, shielding cover with ferrule, plates with slots and pipe-receiving holes, and radiator in the form of directional antenna tilted to inspissated or solidified oil product surface; novelty is that microwave module is rigidly connected through circulator to transmitting line provided with additional straight waveguide mounted between waveguide bend and shielding cover; round top flange of waveguide bend has T-shaped diametric slot to receive heads of bracing bolts uniformly disposed over circumference and hole for their driving in slot; round bottom flange of waveguide bend has holes to receive bracing bolts, and self-alignment joint of flanges has stepped plane; additional straight waveguide as well as shielding cover and radiator rigidly coupled with the latter are free to turn relative to waveguide bend upon loosening nuts on bracing bolts and can be locked in two diametrically opposite positions with aid of locking member that has dowel pin, spring, angle piece with slit, plate, and two locating holes. EFFECT: enhanced effectiveness of heating inspissated oil products in tank cars; reduced labor consumption, enhanced safety. 1 cl, 4 dwg
