Description

Technical Field

[0001] This utility model relates to the field of crude selenium magnetic separation technology, and more specifically, it relates to a magnetic separator for crude selenium separation with anti-clogging function. Background Technology

[0002] In the electrolytic refining process of metals, the metal in the anode dissolves in the electrolyte, while difficult-to-dissolve impurities and precious metals are deposited below the anode plate, forming anode slime. Anode slime is typically rich in precious metals (such as gold and silver), less precious metals (such as selenium and tellurium), and other impurity elements (such as iron, nickel, and lead). Because anode slime contains high-value elements, it requires a series of separation and extraction processes to recover its valuable components.

[0003] In the anode slime treatment process, the extraction of crude selenium is a crucial step in the separation and recovery process. Crude selenium can be obtained from anode slime through chemical leaching or thermal treatment. However, the initially extracted crude selenium often contains a certain amount of impurities, with iron compounds being the most common. The presence of these iron compounds affects the purity of subsequent selenium refining, reducing product quality. Therefore, further purification of the crude selenium is necessary to remove iron impurities.

[0004] In existing technologies, methods such as chemical precipitation and solvent extraction are commonly used to remove iron impurities. However, these methods often suffer from problems such as complex processes, high consumption of chemical reagents, and environmental pollution. Magnetic separation technology has become a more ideal removal method due to the characteristics of iron impurities. Iron and its compounds are mostly magnetic, while selenium and precious metals are usually non-magnetic or weakly magnetic. Therefore, magnetic separation can effectively separate iron compounds, thereby improving the purity of selenium and optimizing subsequent refining processes. Although magnetic separation technology can be used to separate magnetic components from crude selenium, it is prone to agglomeration during storage and processing, forming hard clumps. This agglomeration may be caused by factors such as humidity, oxidation reactions, or electrostatic adsorption. During magnetic separation, agglomerated crude selenium not only obstructs, jams, or even blocks the material flow inside the magnetic separator, but also affects the magnetic separation effect, making it difficult to extract the magnetic components encased within the agglomerates, thus reducing magnetic separation efficiency. Therefore, how to prevent or eliminate agglomeration before magnetic separation and improve the extraction rate of magnetic substances is an urgent problem to be solved in the application of crude selenium magnetic separation technology.

[0005] Therefore, based on the above problems, this application proposes a magnetic separator for crude selenium separation with anti-clogging function. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a magnetic separator for crude selenium separation with anti-clogging function.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A magnetic separator for separating crude selenium with anti-clogging function includes a magnetic separation component for magnetic separation of crude selenium, and a feeding component is provided on the top of the magnetic separation component for crushing agglomerated crude selenium.

[0009] The magnetic separation component includes a mounting frame, on which a rotating drum is mounted. A baffle plate and a magnetic material outlet are mounted on the mounting frame. The baffle plate and the magnetic material outlet are arranged opposite to the two sides of the rotating drum. The magnetic material outlet is used to discharge magnetic material. A material placement chamber is provided at the bottom of the baffle plate. The material placement chamber is used to receive non-magnetic material.

[0010] The present invention is further configured such that: the rotating barrel is configured as a hollow cylindrical structure, a permanent magnet is installed at the center of the rotating barrel, and a rotating component is installed at the same position as the permanent magnet.

[0011] The present invention is further configured such that: the rotating component passes through the side wall of the rotating barrel, and one end of the rotating component is connected to a drive motor.

[0012] The present invention is further configured such that: the baffle plate is arranged vertically, and the baffle plate is spaced apart from the rotating drum by a certain distance; the magnetic material outlet is inclined.

[0013] The present invention is further configured such that: the feeding assembly includes a support frame installed on the top of the mounting frame, and a mounting plate is provided on the support frame, the mounting plate being arranged in a horizontal direction.

[0014] The present invention is further configured such that: a feeding drive and a crushing trough are installed on the top of the mounting plate; the crushing trough is configured as a cuboid with a cavity in the middle; two sets of through holes are opened through the crushing trough; and a feeding trough is provided on the top of the crushing trough.

[0017] The present invention is further configured such that: several sets of crushing parts are sleeved on the two sets of crushing rollers, wherein the crushing parts on the two sets of crushing rollers are arranged alternately.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application pre-treats crude selenium through a feeding assembly, ensuring uniform particle size and sufficient magnetic field effect during magnetic separation, thereby improving separation accuracy. The staggered arrangement of the crushing components prevents material accumulation, improves material throughput, and reduces equipment maintenance frequency. The crushing rollers are driven by gears, and this gear transmission mechanism ensures synchronous rotation of the crushing rollers, improving the overall stability and service life of the equipment.

[0020] 2. The magnetic separator generates a stable magnetic field through permanent magnets within the rotating drum, achieving efficient magnetic separation. This ensures precise adsorption and smooth discharge of magnetic materials, preventing accumulation that could affect sorting efficiency. The rationally designed baffles effectively prevent non-magnetic materials from entering the magnetic material outlet, improving the purity of the magnetic materials. The material feeding chamber features an arc-shaped design, allowing non-magnetic materials to slide smoothly and preventing blockages. Its large internal space can accommodate more non-magnetic materials, reducing operational obstacles caused by accumulation. Attached Figure Description

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] Example 1, please refer to Figures 1-7 The present invention provides the following technical solution:

[0033] Specifically, it refers to a magnetic separator for separating crude selenium with anti-clogging function, including a magnetic separation component 1. The magnetic separation component 1 is mainly used to efficiently separate magnetic and non-magnetic substances in crude selenium. A feeding component 2 is provided on the top of the magnetic separation component 1. The feeding component 2 is used to uniformly feed the raw crude selenium into the magnetic separation component 1 and pre-treat the crude selenium before it enters the magnetic separation component 1 to improve the magnetic separation efficiency. The crushed crude selenium then enters the magnetic separation component 1 for magnetic separation, thus avoiding the blockage of the magnetic separation component 1 by agglomerated crude selenium.

[0034] See Figure 4 The magnetic separator 1 includes a mounting frame 11 on which a rotating drum 12 is mounted. The rotating drum 12 has a hollow cylindrical structure and is designed with appropriate dimensions to allow for the separation of sufficient material while ensuring uniform magnetic field coverage throughout the drum's interior. A permanent magnet 121 is mounted at the center of the rotating drum 12, enabling the magnetic material to be efficiently adsorbed onto the outer wall of the drum 12 and rotate with it. A rotating element 122 passes through the side wall of the rotating drum 12 and is fixed to it, with one end connected to a drive motor 16. When the drive motor 16 starts, the rotating element 122 drives the rotating drum 12 to rotate along its central axis, causing the magnetic material adsorbed on the drum wall to move with the drum and ultimately be discharged to the magnetic material outlet 14.

[0035] See Figures 1-4A baffle plate 13 is vertically mounted on the mounting frame 11 and spaced a distance from the rotating drum 12. Its function is to prevent coarse selenium falling from the feed assembly 2 into the rotating drum 12 from spilling onto the outside of the equipment. A material receiving chamber 131 is provided at the bottom of the baffle plate 13, specifically for receiving non-magnetic materials. A non-magnetic material outlet 15 is provided through the bottom of the material receiving chamber 131 for discharging non-magnetic materials. When non-magnetic materials cannot be attracted by the rotating drum 12, they will fall into the material receiving chamber 131 and be discharged through the non-magnetic material outlet 15.

[0036] See Figure 3 The material placement chamber 131 is designed as an arc-shaped cavity. Its arc shape allows non-magnetic materials to slide off from the arc edge, avoiding congestion. Furthermore, the material placement chamber 131 has a large internal space, which can accommodate a large amount of non-magnetic materials, thus avoiding blockage caused by excessive non-magnetic materials.

[0037] On the other side of the rotating drum 12, there is a magnetic material outlet 14. The magnetic material outlet 14 has a downward-sloping bucket-shaped structure, and a baffle is provided at the top. The baffle is a sheet-like structure with a certain curvature and fits into the corresponding position of the rotating drum 12. When the material rotates counterclockwise with the rotating drum 12 to the bottom of the baffle, the non-magnetic material has already fallen into the feeding chamber 131 due to gravity in the previous section. At this time, the remaining material is all magnetic material. When the magnetic material rotates to the baffle, it is blocked by the baffle and cannot continue to move forward. Therefore, it falls into the magnetic material outlet 14 and is discharged through the outlet.

[0038] See Figure 5 The feeding assembly 2 includes a support frame 21, which is fixedly mounted on the top of the mounting frame 11 to provide stable support. A mounting plate 22 is mounted above it, extending horizontally to ensure the overall stability of the feeding assembly 2 and to provide a mounting platform for the feeding drive 24 and the crushing trough 25. A feeding trough 23 is provided on the top of the mounting plate 22 for supplying material to the crushing trough 25. The feeding trough 23 is a hollow structure with a large top opening. The design of the feeding trough 23 ensures uniform material flow, preventing blockages or accumulation and ensuring the continuity of the crushing process.

[0039] The top of the mounting plate 22 is equipped with a feed drive 24 and a crushing trough 25. The crushing trough 25 is a cuboid structure with a cavity in the middle, which is used to accommodate the incoming material and crush it through the internal crushing rollers 26 and crushing components 27. Two sets of through holes are opened through the crushing trough 25 to fix the crushing rollers 26, allowing them to rotate freely and crush the material. Two sets of crushing rollers 26 are installed at the through holes of the crushing trough 25, and one end of the crushing rollers 26 is connected to the feed drive 24.

[0040] The feed drive 24 drives the two sets of crushing rollers 26 to rotate, thus crushing the material. The feed drive 24 includes a mounting block 241 for fixing the drive unit. Its output end is equipped with a first gear 242, which is sleeved on the outer wall of the first set of crushing rollers 26. The first gear 242 meshes with a second gear 243, which is sleeved on the outer wall of the second set of crushing rollers 26. This gear transmission structure ensures that the two sets of crushing rollers 26 rotate synchronously, thereby achieving a more efficient material crushing process.

[0041] See Figure 6 , Figure 7 Two sets of crushing rollers 26 are installed at the through holes of the crushing trough 25 to crush larger particles of material, making their particle size more uniform. Each set of crushing rollers 26 is fitted with crushing elements 27, which are made of high-hardness material. The staggered arrangement of the crushing elements 27 ensures that the material does not accumulate during the crushing process, improves the crushing uniformity, and makes the material particle size meet the requirements of the magnetic separation component 1.

[0042] Specifically, when crude selenium enters the feed trough 23, it then enters the crushing trough 25 through the feed trough 23. The feed drive 24 is started, which drives the first gear 242 to rotate. The first gear 242 meshes with the second gear 243, which drives the second gear 243 to rotate. The first gear 242 drives a set of crushing rollers 26 connected to it to rotate. The second gear 243 drives a set of crushing rollers 26 connected to it to rotate. The crushing parts 27 on the two sets of crushing rollers 26 rotate alternately to crush the crude selenium. After crushing, the crude selenium then enters the magnetic separation component 1 for magnetic separation.

[0043] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
