Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, specifically to a flotation machine for mineral processing with desulfurization effect. Background Technology

[0002] Flotation machine is short for flotation mineral processing machine. It refers to mechanical equipment that completes the flotation process. In the flotation machine, after the slurry is treated with reagents, it is stirred and aerated, so that some mineral particles are selectively fixed on the air bubbles and float to the surface of the slurry to be scraped off to form a froth product. The rest remain in the slurry, so as to achieve the purpose of separating minerals.

[0003] In some existing mineral processing flotation machines, traditional desulfurization flotation processes typically involve adding a large amount of depressant at once. However, this method of adding depressant results in a fixed dosing point, which prevents the depressant from diffusing throughout the entire flotation machine. This leads to situations where the depressant concentration in localized areas is too high or too low. Simultaneously, some sulfur minerals fail to maintain floatability due to insufficient contact with the depressant, rising with the froth and contaminating the concentrate, resulting in incomplete desulfurization. Therefore, we propose a mineral processing flotation machine with desulfurization capabilities to address these issues. Utility Model Content

[0013] Compared with the prior art, this utility model provides a flotation machine for mineral processing with desulfurization effect, which has the following beneficial effects:

[0014] 1. This desulfurization flotation machine for mineral processing, through the cooperation of the first gear, the second gear, the rotating ring connecting inclined tube, and the feed inlet, enables the rotating ring and the connecting inclined tube to perform continuous circular motion. This allows the inhibitor output from the storage tank to be periodically added to different positions inside the flotation machine through the feed inlets at different locations. This effectively ensures that the inhibitor diffuses rapidly and is evenly distributed in the slurry, effectively avoiding incomplete sulfide inhibition in local areas due to insufficient inhibitor concentration, thereby improving the desulfurization effect and concentrate quality.

This desulfurization flotation machine for mineral processing, through the coordination between the motor, stirring shaft, transmission mechanism, first gear and second gear, etc., allows the device to simultaneously complete the two functions of slurry stirring and circumferential addition of inhibitors with only one motor. There is no need to configure a separate power source for the dosing of reagents. The structure is compact, the energy consumption is low, and it effectively prevents the reagents from being too concentrated or too diluted in some places, thus reducing production costs.

[0027] A discharge pipe 11 is provided on the lower surface of the storage box 10. A rotating flange 12 is provided between the discharge pipe 11 and the connecting inclined pipe 5. The discharge pipe 11 and the connecting inclined pipe 5 are connected through the rotating flange 12. A solenoid valve 13 is also provided on the discharge pipe 11. The solenoid valve 13 facilitates the control of the discharge efficiency of the discharge pipe 11 and the opening and closing of the discharge pipe 11, thereby improving the automation level of the device.

[0028] The upper end face of the storage tank 10 is provided with a feed pipe 14 that communicates with the inside of the storage tank 10.

Several stirring blades 17 are fixedly connected to the outside of the stirring shaft 16. The upper end of the stirring shaft 16 rotatably penetrates into the interior of the cavity 7. A motor 18 is fixedly connected to the upper surface of the cover plate 2. The output shaft of the motor 18 rotatably penetrates into the interior of the cover plate 2 and is fixedly connected to the upper end of the stirring shaft 16 via a coupling. By starting the motor 18 through an external controller, the stirring shaft 16 can be driven to rotate, thereby driving the stirring blades 17 to stir and mix the materials inside the flotation machine body 1, ensuring the desulfurization effect.

[0030] Among them, the motor 18 is matched with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail.

[0031] The transmission assembly includes a first support shaft 19, which is rotatably connected inside the cavity 7. A first gear 20 is fixedly sleeved on the outside of the first support shaft 19. A communicating groove 21, which communicates with the rotating groove 3, is opened on the inner wall of the cavity 7.

[0033] The cavity 7 is equipped with a transmission mechanism 25, which includes two synchronous pulleys and a synchronous belt. The two synchronous pulleys are respectively fixedly sleeved on the outside of the stirring shaft 16 and the first support shaft 19.

[0034] In the above embodiments, the flotation machine body 1 is also equipped with a feeding hopper and support legs. Since these are all existing technologies, they will not be described in detail here.

[0035] Working principle:

[0036] When in use, the flotation machine for mineral processing with desulfurization effect can drive the stirring shaft 16 to rotate by starting the motor 18 through the external controller, thereby driving the stirring blades 17 to stir and mix the material inside the flotation machine body 1, ensuring the desulfurization effect.

[0037] In addition, when the stirring shaft 16 rotates, the transmission mechanism 25 can stably drive the first support shaft 19 to rotate by means of the synchronous pulley and synchronous belt. The rotation of the first support shaft 19 can drive the rotation of the first gear 20, and the rotation of the first gear 20 can drive the rotation of the second gear 23. The rotation of the second gear 23 and the engagement of the tooth groove 24 can drive the rotating ring 4 to rotate slowly. The rotation of the rotating ring 4 can drive the connecting inclined tube 5 to perform circumferential motion with the rotating flange 12 as the connection point, so as to facilitate the subsequent material feeding through the feeding port 6 at different positions.

[0038] At the same time, the staff can open the solenoid valve 13 set on the outside of the discharge pipe 11. The inhibitor inside the storage tank 10 will enter the interior of the connecting inclined pipe 5 through the discharge pipe 11 and the rotating flange 12. When the connecting inclined pipe 5 is connected to any discharge port 6, the material can be added into the interior of the flotation machine body 1 through the discharge port 6, thereby ensuring the uniformity of inhibitor input and effectively avoiding local concentrations that are too high or too low.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
