Energy-gathering ultrasonic scrubbing device, and intensive desliming system for argillaceous sandstone uranium ore

Abstract

An energy-gathering ultrasonic scrubbing device includes a scrubbing cylinder, a reverse stirring system, an energy-gathering ultrasonic vibrator and a slurry storage tank. The reverse stirring system is located inside the scrubbing cylinder. It includes a rotating shaft and at least four layers of reverse stirring blade structures arranged in an axial direction of the rotating shaft. Each layer of reverse stirring blade structure includes several blades arranged in a circumferential direction of the rotating shaft. Inclination directions of blades of two adjacent layers relative to the rotating shaft are opposite. The energy-gathering ultrasonic vibrator includes an ultrasonic transducer and an energy-gathering vibration transmitting rod. The ultrasonic transducer is fixed outside of the scrubbing cylinder. The energy-gathering vibration transmitting rod is connected to the ultrasonic transducer and located inside the scrubbing cylinder. A discharge port of an overflow residue discharge pipe is directly guided to the slurry storage tank.
