AGITATING DEVICE

摘要

PURPOSE:To reduce driving power cost by providing a guide cylinder provided with slit holes to the inside of a cylindrical vessel and providing agitating vanes in proximity to the outside wall of the guide cylinder. CONSTITUTION:The liquid in the vessel 1 rises on the outer side of the guide cylinder 3 and the flow falling down on the inner side is generated by rotation of the helical ribbon vanes as a revolving shaft 8 revolves in a direction 21 in the full liquid state in which the liquid level exists at the position upper than the top end of the guide cylinder 3. The liquid is circulated to the inner side of the guide cylinder 3 from the slits 5 provided to the guide cylinder 3 even if the liquid level falls below the top end of the guide cylinder 3 when there is a fluctration in the volume of the liquid to be controlled. The inside wall surface 2 of the vessel 1 and the outside wall surface 29 of the guide cylinder 3 act as heat transfer surfaces and since the ribbon vanes 4 rotate in proximity to the heat transfer surfaces, the film coefft. of heat transfer of the heat transfer surfaces is greatly improved. The temp. control is improved in this way.
