HEAT-TRANSFER DEVICE WITH RIGID DRIVE FOR CONTACT CORE MOVING IN ORBIT Russian patent published in 2000 - IPC

FIELD: heat-transfer devices for evaporation, distillation, freezing or cooling of liquids. SUBSTANCE: heat- transfer device for continuous treatment of liquid has a reliable mechanical drive for a number of vertical contact cores, each located in a vertical heat-transfer pipe. Each core freely stays on its lower end, and it is sufficiently flexible to tightly contact with the pipe inner surface as it moves in orbit. The contact core is set in motion by the planetary drive directly through two horizontal plates being apart from each other in vertical, which engage the cores in holes freely enclosing them, that serve as outlets for liquid running out from the drive plate. The motor rotates the drive shaft connected at least to one drive plate through at least one eccentric crank. Each plate may represent an oppositely located pair of plates with separate eccentric drives shifted in phase by 180 deg. relative to each other to ensure self-balancing. A plate of another shape represents a rigid round ring with a wire netting attached to it, in which bushings are secured for engagement of the core. Distribution of liquid may be also accomplished from the water source, held between the fixed plate and upper drive plate, with liquid fed to each pipe under gravity through the inlet opening of the respective size in the pipe upper end. For isolation of the heat-transfer process use is made of various seals for transmission of torque through a container without any use of standard seals for rotating parts. EFFECT: reduced power consumption and improved sealing of liquid treated in heat- transfer devices used for evaporation, distillation, cooling and freezing. 15 cl, 10 dwg
