Description

Technical Field

[0001] The present invention relates to the technical field of ore dressing equipment, and particularly relates to a flotation device for recovering crude copper concentrate powder. Background Art

[0002] In the process of copper ore mining and subsequent processing, the recovery of crude copper concentrate powder is crucial for improving the utilization rate of copper resources and reducing production costs. Traditional flotation devices have many defects when dealing with crude copper concentrate powder. For example, the foam generated during the flotation process has poor fluidity and is difficult to carry the crude copper concentrate powder to the discharge port. Moreover, the energy-saving design in traditional flotation devices is not good, and it is difficult to recover the waste heat of the tailings, resulting in waste of heat energy. Therefore, a flotation device for recovering crude copper concentrate powder is provided now. Summary of the Invention

The upper-layer bubbles are blown by a fan to move towards the refined copper discharge nozzle, which improves the fluidity of the bubbles. The ultrasonic generator generates high-frequency electrical signals, and the transducer converts the high-frequency electrical signals into mechanical vibrations, thereby driving the defoaming plate to vibrate and eliminate the nearby bubbles. Finally, the refined copper concentrate powder is discharged from the refined copper discharge nozzle, thus improving the recovery efficiency of the refined copper concentrate powder. The waste heat of the pulp is absorbed by the fluid in the heat exchange coil to realize heat recovery and reduce heat waste, overcoming the deficiencies of the prior art.

[0026] The defoaming component includes a defoaming plate 25 arranged at the refined copper discharge nozzle 4. The upper end of the defoaming plate 25 is connected to a top plate 13. An ultrasonic generator 15 and a transducer 14 are fixed to the upper end of the top plate 13. Support springs 27 are fixedly connected between the two sides of the defoaming plate 25 and the inner walls of the two sides of the refined copper discharge nozzle 4 respectively.

[0027] Through holes 26 are arranged equidistantly on the defoaming plate 25. A gap is reserved between the lower end of the defoaming plate 25 and the bottom end of the refined copper discharge nozzle 4.

[0028] A retaining ring 16 is arranged at the bottom end of the flotation cell 2, and the top end of the retaining ring 16 is located above the bottom end of the defoaming plate 25.

[0029] The stirring component includes a servo motor 22 fixed to the outer wall of the bottom of the flotation column body 1. The output end of the servo motor 22 extends into the flotation column body 1 and is connected to a rotating shaft 23. A spiral blade 24 is fixed to the outer wall of the rotating shaft 23.

[0030] The circulation component includes a pumping pipe 9 connected to the bottom of the flotation column body 1. One end of the pumping pipe 9 is connected to the pumping end of a pump body 8, and the discharging end of the pump body 8 is connected to a discharging pipe 7.

[0031] The foaming component includes a microbubble generator 11 connected to one end of the discharging pipe 7. The discharging end of the microbubble generator 11 is connected to a feeding pipe. One end of the feeding pipe is connected above the bottom of the flotation column body 1. An electromagnetic valve 12 is installed at the air inlet end of the microbubble generator 11. One end of the electromagnetic valve 12 is connected to an air inlet pipe 6, and one end of the air inlet pipe 6 is externally connected to an air compressor.

The heat exchange coil 21 absorbs the heat of the flotation column body 1, and the fluid is used to take away the heat absorbed by the heat exchange coil 21, thereby realizing heat recovery, reducing heat waste, and indirectly reducing production costs.
