Description

Technical Field

[0001] This utility model relates to the field of mineral sorting technology, and more specifically to a device for improving the flotation of coarse-grained minerals. Background Technology

[0002] During mineral processing tests, coarse particle flotation faces multiple challenges. Coarse particles have large mass and high inertia, making them difficult to capture by air bubbles (low probability of collision). Coarse particles settle quickly and tend to accumulate at the bottom of the flotation cell, leading to the "sanding" problem. Traditional laboratory flotation machines struggle to maintain uniform suspension, easily causing the loss of coarse target minerals in the tailings.

[0003] Currently, traditional laboratory flotation devices primarily use mechanical agitation or aeration devices in the flotation cell to draw air into the slurry. Under the action of flotation reagents, the slurry generates a large number of microbubbles, and the target mineral particles float to the surface after mineralization on the bubble surface. The main drawbacks of traditional laboratory flotation devices are: the turbulent flow field generated by high-speed agitation often causes coarse mineral particles to detach, making effective recovery difficult; and the bubbles do not adhere well enough to coarse mineral particles, leading to desorption and limiting their applicability. Utility Model Content

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other. Example 1

[0020] An apparatus for improving the flotation of coarse-grained minerals, as shown below. Figure 1-5 As shown, the system includes a tank body 1 with a feed inlet 2 at the top, through which mineral slurry enters the tank body 1. A fixed column 3 is fixedly connected to the top wall of the tank body 1, and a flow guiding component 4 is rotatably connected to the fixed column 3. The flow guiding component 4 guides and disperses the mineral slurry entering the tank body 1, increasing the contact opportunity between the minerals and flotation reagents. A filter port 5 is provided on one side of the tank body 1, with a filter screen 6 fixed thereon. The filter screen 6 filters coarse mineral particles while allowing small particles to pass through. A collection cylinder 7 is connected to the filter port 5, and the collection cylinder is connected to the input end of a peristaltic pump 8 via a pipe. A pressure chamber 9 is provided at the bottom of the tank body 1, and the output end of the peristaltic pump 8 is connected to the pressure chamber 9 via a pipe. This design allows a portion of the slurry filtered by the filter screen 6 to be pumped to the pressure chamber 9 by the peristaltic pump 8, achieving slurry circulation within the tank body 1. Inside the tank 1, below the flow guiding assembly 4, there is a fixed upward flow distribution plate 10. The upward flow distribution plate 10 has evenly distributed flow diversion holes 11. On the one hand, the upward flow distribution plate 10 can make the fluid rising from the pressurization chamber 9 evenly distributed. On the other hand, it can make the liquid flowing into the pressurization chamber 9 pressurized and rise, increasing the mixing uniformity of the liquid inside the tank 1, thereby improving the flotation effect. A slag-separating port 21 is provided on the lower outer side of the tank body 1. A slag-separating membrane 22 is fixed inside the slag-separating port 21. The slag-separating port 21 is used to discharge excess liquid in the tank body 1, and the slag-separating membrane 22 can prevent the discharge of minerals. A reagent addition tank 23 is installed between the peristaltic pump 8 and the pressure chamber 9, which contains flotation reagents. The peristaltic pump 8 and the reagent addition tank 23 enable the circulation of slurry and the timely addition of flotation reagents, thereby further improving the flotation effect.

[0021] The flow guiding assembly 4 includes a rotating platform 12, which is inverted conical in shape. This shape facilitates the dispersion of mineral slurry on the surface of the rotating platform 12. The rotating platform 12 is rotatably connected to the fixed column 3. Flow guiding plates 13 are evenly distributed on the outer side of the rotating platform 12 and are inclined on the outer surface of the rotating platform 12. When the mineral slurry impacts the flow guiding plates 13, it pushes the rotating platform 12 to rotate. At the same time, the flow guiding plates 13 further disperse the slurry, improving the flotation effect. Limiting rings 14 are fixedly connected to the fixed column 3 at the upper and lower ends of the rotating platform 12. The limiting rings 14 are used to prevent axial displacement of the rotating platform 12 during rotation.

[0022] As a preferred embodiment, the inner side of the tank body 1 is also vertically fixed with evenly distributed guide vanes 15, which can guide the flow direction of the fluid in the tank body 1, so that the fluid forms an orderly circulation in the tank body 1 and improves the flotation efficiency.

[0023] An air inlet pipe 16 is fixed inside the tank body 1 between the upflow distribution plate 10 and the flow guiding assembly 4. The air inlet pipe 16 is evenly distributed with air inlet heads 17, which are used to introduce air into the tank body 1 to generate bubbles, provide bubble carriers for mineral flotation, and further improve the flotation effect.

[0024] The pressurization chamber 9 is equipped with a pressurization motor 18, and the output end of the pressurization motor 18 is fixedly connected to an impeller 19. The pressurization motor 18 drives the impeller 19 to rotate, pressurizing the fluid entering the pressurization chamber 9 so that it can enter the tank 1 through the rising flow distribution plate 10 at a certain pressure.

[0025] An overflow port 20 is provided on the upper outer side of the tank body 1 for discharging the concentrate foam obtained by flotation. Example 2

[0026] As a further improvement to the above embodiments, the following technical solutions are provided: Figure 1 As shown, in order to achieve unidirectional upward flow of liquid in the pressurization chamber 9 and avoid liquid backflow, a one-way valve 24 is installed on the pipeline between the medicine addition tank 23 and the pressurization chamber 9. Example 3

[0027] As a further improvement to the above embodiments, the following technical solutions are provided: Figure 2 As shown, in order to facilitate the disassembly of the pressurization chamber 9 and the regular cleaning and maintenance of the interior of the pressurization chamber 9, the pressurization chamber 9 is threadedly connected to the bottom of the tank body 1.
