The invention provides an effective
slurry thick and stable discharging device and method and belongs to the technical field of
flocculation settling. The device comprises a cabin body,
transducer carrier tubes, sound / ultrasonic transducers, a digital controller, a rotation driving device, a mixing
helix tube, a flocculant tube, an overflow
pipe, a barretter, a carrier tube stabilizer and a sand outlet, wherein the
transducer carrier tubes are arranged inside the cabin body, the rotation drive device is arranged at the upper end of the cabin body, and thus a rotation blind-less scanning systemis formed; the sound / ultrasonic transducers are respectively arranged at a
settling section, a thickening section and a discharging section in each
transducer carrier tube to form a
sound field destabilization granulating active region, a
sound field resonant draining thickening active region and a
sound field excitation liquefying
discharge active region respectively, and are connected with thesound / ultrasonic transducers through transducer connecting wires; the mixing
helix tube is connected with the flocculant tube and is communicated with the barretter. The device has simple structure and process, and can realize quickly thick and stable discharging of
slurry.
