Description

Technical Field

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

[0002] A wet magnetic separator is a device that uses a magnetic system made of permanent magnet materials to perform wet magnetic separation. In this type of magnetic separator, the strong magnetic field generated by the permanent magnet system can effectively separate magnetic ore particles or other materials. The term "wet" means that water is required during its operation, and the separation of materials is usually carried out in a suspension. Permanent magnet wet magnetic separators are commonly used in the mining and metallurgical industries to separate magnetic minerals, such as iron ore, from ores. Compared to traditional wet magnetic separators, permanent magnet wet magnetic separators typically have stronger magnetic force, higher separation efficiency, and more stable performance. These devices play an important role in the mining and metallurgical industries.

[0003] In the existing technology, the slurry is directly fed into the tank, and then the magnetic minerals in the slurry are separated by a magnetic separator. However, in actual use, the slurry does not have a dispersing function after entering the tank. The magnetic minerals in the slurry are easily mixed with impurities, making them difficult to be adsorbed by the magnetic separator. At the same time, the separated magnetic minerals are prone to contain impurities, which affects the beneficiation effect. Therefore, there is room for improvement. Utility Model Content

[0004] This invention provides a wet magnetic separator for mineral processing to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model provides a wet magnetic separator for mineral processing, comprising a housing and a magnetic separator drum. The housing is hollow inside, with a discharge port on one side and a drain port on the other side. A feed box is located at the top of the housing. The magnetic separator drum is rotatably disposed inside the housing, and a drive mechanism for rotating the magnetic separator drum is located at one end of the housing exterior. A feed inlet is located in the middle of the feed box, and a discharge pipe is located at the bottom of the feed box, positioned above the magnetic separator drum on the side closest to the drain port.

[0006] Preferably, the magnetic separator is provided with baffles at both ends, and the discharge pipe is located between the baffles at both ends of the magnetic separator.

[0007] Preferably, the discharge port is provided with a scraper that conforms to the surface of the magnetic separator, and baffles are provided on both sides of the scraper.

[0008] Preferably, a stirring shaft is rotatably installed inside the feeding box, and several stirring rods are evenly installed on the stirring shaft. One end of the stirring shaft is rotatably extended to the outside of the feeding box and is connected to a motor via a belt. The motor is installed at the upper part of one end of the feeding box.

[0009] The beneficial effects of adopting the above technical solutions are:

[0010] 1. The stirring shaft is driven by a motor to rotate inside the feed box, thereby stirring the slurry fed into the feed box, so that the magnetic minerals are separated from the impurities more thoroughly, which facilitates the subsequent beneficiation work of the magnetic separator.

[0011] 2. By setting baffles at both ends of the magnetic separator, the slurry can be guided, thereby improving the working efficiency of the magnetic separator. Attached Figure Description

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0019] like Figure 1-3 In this embodiment, a wet magnetic separator for mineral processing includes a housing 1 and a magnetic separator 2. The housing 1 is hollow inside, with a discharge port 11 on one side and a drain port 12 on the other side. A feed box 3 is provided on the top of the housing 1. The magnetic separator 2 is rotatably disposed inside the housing 1, and a drive mechanism 21 for driving the magnetic separator 2 to rotate is provided at one end of the outer side of the housing 1. A feed port 31 is provided in the upper middle part of the feed box 3, and a discharge pipe 32 is provided at the bottom of the feed box 3. The discharge pipe 32 is located above the magnetic separator 2 on the side near the drain port 12.

[0020] Through the above technical solution, the slurry is fed into the feed box 3 through the feed inlet 31. The slurry is then stirred in the feed box 3 to make the magnetic minerals and impurities more thoroughly separated. The slurry is then fed into the magnetic separator 2 inside the shell 1 through the discharge pipe 32. The magnetic separator 2 is driven to rotate by the drive mechanism 21 to perform mineral beneficiation. The selected magnetic minerals are discharged through the discharge outlet 11 in the shell 1, and the slurry after the magnetic minerals are selected is discharged from the drain outlet 12, thus completing the mineral beneficiation work.

[0021] Preferably, the magnetic separator 2 is provided with baffles 22 at both ends, and the discharge pipe 32 is located between the baffles 22 at both ends of the magnetic separator 2.

[0022] Through the above technical solution, the baffle plate 22 can guide the slurry fed into the discharge pipe 32, preventing the slurry from rushing into both sides of the magnetic separator 2, thereby improving the stability and efficiency of the magnetic separator 2 during mineral processing.

[0023] Preferably, the top of the discharge port 11 is provided with a discharge spray pipe 111 and a scraper 112 that fits the surface of the magnetic separator 2, and baffles 113 are provided on both sides of the scraper 112.

[0024] Through the above technical solution, the unloading nozzle 111 sprays water in conjunction with the scraper 112 to unload the magnetic minerals adsorbed on the surface of the magnetic separator 2, so that the magnetic minerals are discharged along the surface of the scraper 112.

[0025] Preferably, a stirring shaft 33 is rotatably installed inside the feed box 3, and several stirring rods 34 are installed at equal intervals on the stirring shaft 33. One end of the stirring shaft 33 is rotatably extended to the outside of the feed box 3 and is connected to a motor 35 via a belt. The motor 35 is installed on the upper part of one end of the feed box 3.

[0026] Through the above technical solution, the slurry in the feed box 3 is driven by the motor 35 to make the stirring shaft 33 rotate in the feed box 3. The stirring shaft 33 drives the stirring rod 34 to rotate, thereby stirring and dispersing the slurry in the feed box 3, so that the magnetic minerals and impurities in the slurry are separated more thoroughly, thereby improving the efficiency and effect of subsequent mineral processing.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
