Description

Technical Field

[0001] This utility model relates to the field of magnetic separator mineral processing technology, and in particular to a high-precision wet magnetic separator. Background Technology

[0002] In the process of separating magnetic minerals, wet magnetic separators are usually used to effectively separate iron minerals from gangue minerals by utilizing the differences in the strength of the magnetic properties of the minerals, thereby improving the grade of iron concentrate. However, problems such as fine ore particle size, dense coexistence of magnetic minerals and gangue minerals, excessively high pulp concentration, or excessively high flow rate may occur during mineral separation. Traditional wet magnetic separators may result in low concentrate grade and poor separation effect. As the core equipment for iron ore beneficiation, the technological advancement of wet magnetic separators is directly related to the utilization efficiency and economic benefits of iron ore resources. It is an indispensable key link in modern mineral processing technology. Therefore, a high-precision wet magnetic separator is provided. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4 A high-precision wet magnetic separator includes a body 1. A ore collection trough 6 is located on one side of the bottom of the body 1, and a concentrate trough 7 is located on the other side of the bottom of the body 1. A first support rod 12 is fixed to the inner wall of the body 1 above the ore collection trough 6, and a first roller 4 is sleeved on the outside of the first support rod 12. A second support rod 14 is fixed to the inner wall of the body 1 above the concentrate trough 7, and a second roller 5 is sleeved on the outside of the second support rod 14. A first servo motor 8 and a second servo motor 9 are installed on one side of the outer wall of the body 1. The output end of the first servo motor 8 is connected to one end of the first roller 4, and the output end of the second servo motor 9 is connected to one end of the second roller 5. Next, first magnets 13 are evenly spaced on one side of the bottom of the outer wall of the first support rod 12, and second magnets 15 are evenly spaced on one side of the top of the outer wall of the second support rod 14. A feeding component is fixed on one side of the inner wall of the machine body 1, and a tailings collection component is provided at the bottom of the feeding component. A first spray pipe 18 is installed on the top of the machine body 1 above the part between the first roller 4 and the second roller 5, and a second spray pipe 19 is provided on the top of the machine body 1 above the second roller 5. Spray nozzles are evenly spaced on both the first spray pipe 18 and the second spray pipe 19, and one end of both the first spray pipe 18 and the second spray pipe 19 is connected to a water supply pipe.

[0021] The first support rod 12 is connected to the first roller 4 by a bearing, and the second support rod 14 is connected to the second roller 5 by a bearing.

[0022] The feeding assembly includes a feeding box 2 fixed to the top of the inner wall of the machine body 1 and located on one side of the first roller 4. The bottom of the feeding box 2 is set to be open. The inner wall of the feeding box 2 is fixed with a filter screen 3 by bolts.

[0023] The tailings collection assembly includes a partition 17 fixed to the inner wall of the body 1 and located on one side of the lower end of the feeding box 2. A tailings trough 10 is fixed in the middle of the partition 17, and the bottom end of the tailings trough 10 extends to the outside of the body 1. The length of the tailings trough 10 is less than the length of the partition 17.

[0024] The minerals are fed into the feeding box 2, where they first pass through a filter screen 3 to remove large particles of impurities, preventing them from entering the machine body 1 and causing blockages and equipment wear. The first servo motor 8 drives the first drum 4 to rotate, and the second servo motor 9 drives the second drum 5 to rotate. When the minerals come into contact with the first drum 4, the magnetic material is attracted by the first magnet 13 and adheres to the surface of the first drum 4. As the first drum 4 rotates, the magnetic material gradually moves upwards, while the non-magnetic material is carried into the tailings trough 10 by the water flow. After the magnetic material rises to the position of the first magnet 13, it is washed by the first spray pipe 18. The magnetic minerals are dispersed and fall off under the action of the impact water flow. The second drum 5 then performs secondary recovery of the scattered magnetic material and removes the gangue minerals to achieve the purpose of fine selection. The removed minerals fall back into the feed liquid surface and flow into the tailings tank 10 with the water flow. The fine minerals adhere to the surface of the second drum 5 and fall into the concentrate tank 7 in the position where there is no second magnet 15 as the second drum 5 rotates.

[0025] Example 2 is an optimization based on Example 1, specifically:

[0026] Valves 11 are installed at the bottom of the ore collection trough 6, the bottom of the concentrate trough 7, and the bottom of the tailings trough 10. Support legs 16 are installed at the bottom of the machine body 1. During the magnetic separation process, the three valves 11 are opened respectively to control the flow rate.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
