Example Embodiment

[0070] Example 1 A single-machine flotation device

[0071] figure 1 Shown is a single-machine flotation device for realizing a single-machine flotation method, including an ultrasonic dispersion device 39 , a helical rotor flotation device 30 , a tailings diversion device 18 and a liquid cleaning device 12 . The cleaning liquid 9 is injected into the floating pulp 21 in the area below the liquid level 8 of the flotation chamber through the cleaning liquid outlet 15 provided on the outer wall of the lower converging hollow cone 13; More than one spiral channel 19 on the inner wall of the chamber wall 27 is enriched and settled, and ultrasonic flotation is continuously carried out during the spiral flow to the tailings outlet 22 .

[0072] It can be seen that the lower converging hollow cone 13 of the liquid cleaning device 12 rotating at a slow speed forms a swirl force in the same direction as the rotating direction of the ore pulp 21 after the floating, and strengthens th...

Example Embodiment

[0077] Embodiment 2 Another stand-alone flotation device

[0078] figure 2 Shown is another single-machine flotation device for realizing a single-machine flotation method, including an ultrasonic dispersion device 39 , a helical rotor flotation device 30 , a tailings diversion device 18 and a liquid cleaning device 40 . It can be seen that its technical principle and working process are the same as those of the first embodiment. The difference is that the cleaning liquid 9 is injected into the floated pulp 21 in the area below the liquid level 8 of the flotation chamber through at least one cleaning liquid outlet 42 provided outside the outer wall of the lower converging hollow cone 41 .

[0079] The advantage of this chemical liquid cleaning device 40 is that the cleaning chemical liquid 9 can be injected into the floated ore slurry 21 by means of a pump spray, so as to enhance the diffusion effect of the cleaning chemical liquid 9 .

Abstract

The invention provides a one-machine flotation method and a device. The device comprises a flotation cavity; a tailings shunting device is arranged on the inner wall surface of the flotation cavity, and comprises more than one spiral channel; an ultrasonic generation device is arranged on the outer wall surface of the flotation cavity; a spiral rotor floating device is arranged at the bottom of the flotation cavity; ore pulp enters into the flotation cavity, and then accomplishes the bubble formation process and the mineralization processes through the spiral rotor floating device synchronously to produce floated ore pulp; floated ore pulp upwards unidirectionally flows in the flotation cavity in a spiral flow state under the guidance of the spiral flow inertia force provided by a spiral rotor to form mineralized bubbles to be discharged from a mineralized bubble outlet; and finally, the flotation process is finished. In the invention, the tailings shunting device is adopted to achieve the continuous scavenging process to outflowing tailings; an ultrasonic dispersion device, the spiral rotor floating device, the tailings shunting device and a liquid medicine cleaning device jointly form a one-machine flotation flow, so that the bubble formation and mineralization effects are fully improved, and the separation of the mineralized bubble from the tailings particles is fully improved with a high efficiency.

Description

Technical field [0001] The invention relates to a flotation method and device, in particular to a single-machine flotation method and device for synchronously completing continuous sweeping and continuous beneficiation in a flotation machine, and belongs to the technical field of flotation. Background technique [0002] The well-known flotation process is completed by using more than one flotation machine to form a multi-machine flotation system. Each flotation machine performs flotation on the incoming ore slurry to produce a concentrate slurry and a tailings slurry. In the closed-circuit flotation mode, the tailings slurry flows into the flotation system of the current stage step by step, and the flotation machine is installed behind it for sweeping, until the final tailings are produced; Be refined until the final concentrate is produced. In the open-circuit flotation mode, the tailings slurry flows into the flotation system of the current stage step by step, and then t...
