DEVICE FOR AERATION OF LIQUIDS (VERSIONS)

摘要

FIELD: aeration of liquids, including those containing suspensions; biological cleaning of sewage; floatation units; fishing industry. SUBSTANCE: proposed device has chamber made from cylindrical shell and provided with bottom and cover; it has form of hollow truncated cone with holes over generatrix and vertex directed to pump inlet; its narrowing portion is provided with cylindrical conical inlet branch pipe for connection of pump with water basin or reservoir. Mixing unit is made in form of conical shell with long slots located at angle relative to generatrices and terminating in taper fairing with turbine blades. According to second version, end of fairing of mixing unit has no turbine blades and is directly connected with rotor of bladed pump by means of rigid movable compensating coupling. EFFECT: enhanced efficiency. 6 cl, 6 dwg
