Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mineral flotation, in particular to a rough mineral flotation device. Background Art
[0002] With the development of industry, the demand for various mineral resources is increasing. Many minerals exist in the form of complex ores, among which useful minerals are often closely symbiotic with gangue minerals. In order to effectively separate and enrich useful minerals, appropriate mineral processing methods are needed. Flotation, as an effective mineral separation method, has a development history of more than a century. The principle of mineral flotation is mainly based on the differences in the physical and chemical properties of the mineral surface. By adding specific flotation agents, the target minerals are selectively attached to the bubbles and rise to the surface of the mineral mixture with the bubbles to form a foam layer, thereby achieving separation from the gangue minerals.
[0003] In the mineral processing process, rougher flotation is typically the first step, designed to quickly separate the majority of useful minerals from gangue minerals to improve the efficiency of subsequent concentration operations. However, during daily production, heavier particles in the mineral mixture tend to settle at the bottom of the rougher flotation unit. Over time, the effective volume within the unit decreases, resulting in a decrease in flotation capacity and lower efficiency per unit time. Frequent cleaning of the rougher flotation unit inevitably impacts normal production progress. Utility Model Content
[0004] In order to overcome the deficiencies of the above-mentioned prior art, the utility model provides a rough mineral flotation device, which solves the technical problem that during the use of the rough flotation device, heavier particles in the mineral mixture will be deposited at the bottom of the flotation device, causing the effective volume in the flotation device to become smaller, the flotation amount of the flotation device to become less per unit time, and the efficiency to become lower.

The cylinder 1 is provided with a cavity 10, the bottom plate 2 is tiltedly arranged at the cavity 10, and extends radially along the cylinder 1 to the inner wall of the cylinder 1. A heating component 3 is provided in the cavity 10, and the heating component 3 is detachably suspended on the cylinder 1. An injection component 4 is provided on the outer wall of the cylinder 1, and the injection component 4 includes: an injection outlet 40, the injection outlet 50, and the injection outlet 50. The outlet 40 extends into the cavity 10 and is arranged facing the highest point of the inclination of the bottom plate 2. The drain port 5 is arranged on the side wall of the cylinder 1. The drain port 5 is arranged higher than the lowest point of the inclination of the bottom plate 2. The upper end of the cylinder 1 is radially extended outward to provide an overflow groove 6. The bottom of the overflow groove 6 is arranged lower than the upper opening of the cylinder 1. The bottom of the overflow groove 6 is provided with an overflow hole 60. The overflow hole 60 is used for the outflow of the upper reaction solution in the cylinder 1. A stirring component 7 is provided in the cylinder 1. The stirring component 7 is used to stir the reaction solution in the cylinder 1.
[0025] Based on the above structure, the principle of the mineral rough flotation device is as follows: the mineral mixture is injected into the chamber 10 at a preset flow rate through the liquid injection component 4, the stirring component 7 is in the open state, used to stir the mineral mixture to prevent the stirred mineral mixture from settling in the cylinder 1, and at the same time cooperates with the heating component 3 to make the mineral mixture heated more fully; the valve (not shown) on the discharge port 5 is in the closed state, when the liquid level in the chamber 10 is higher than the working liquid level of the heating component 3, the heating component 3 starts to work to the preset temperature, heats the mineral mixture, makes the reaction more complete and intense, During the reaction, a large amount of foam (carrying useful minerals) floats on the surface of the mineral mixture. When the liquid level in cylinder 1 exceeds the bottom of overflow tank 6, the foam (carrying useful minerals) is discharged from cylinder 1 through overflow hole 60, and the lower layer of reaction solution (gangue minerals and impurities) is discharged from cylinder 1 through drain port 5. The bottom plate 2 is tilted within cylinder 1. This design promotes the flow of the mineral mixture within cylinder 1 and facilitates the discharge of the lower layer of reaction solution.

The first connecting tube 43 and the second connecting tube 44 are connected to the bottom and the middle of the first injection tube 41 and the second injection tube 42 respectively. The liquid injection assembly 4 is used to inject the mineral mixture into the cylinder 1. The first liquid injection pipe 41 and the second liquid injection pipe 42 form a U-shaped pipe structure. When the mineral mixture is injected into the cylinder 1 through the liquid injection port 420 on the second liquid injection pipe 42, if the pressure difference between the liquid injection port 420 and the liquid injection outlet 40 is too large, it will cause damage to the first liquid injection pipe 41 or the second liquid injection pipe 42. The design of the first connecting pipe 43 and the second connecting pipe 44 allows liquid to flow in the pipe, so that the pressure in the first liquid injection pipe 41 and the second liquid injection pipe 42 is balanced, thereby preventing damage to the first liquid injection pipe 41 or the second liquid injection pipe 42. The first connecting tube 43 includes: a pair of L-shaped connecting tubes 431, the pair of L-shaped connecting tubes 431 are arranged opposite to each other, and the two ends of the pair of L-shaped connecting tubes 431 are respectively connected to the bottom of the first injection tube 41 and the second injection tube 42 through flanges; the second connecting tube 44 includes: a pair of connecting tubes 441, one end of the pair of connecting tubes 441 is respectively connected to the first injection tube 41 and the second injection tube 42, and the pair of connecting tubes 441 are axially connected.
