A magnetic separation device

Abstract

This utility model discloses a magnetic separation device, belonging to the field of mining equipment. It includes a shell, a material input structure, a transmission mechanism, a vibrating motor, a magnetic separation drum, a material output structure, a support frame, a drive motor, and a transmission mechanism. The vibrating motor drives the transmission mechanism to vibrate, and materials not adsorbed by the magnetic separation drum and materials adsorbed by the magnetic separation drum are respectively output through two material output structures. In this magnetic separation device, after entering the shell, the material first falls onto the transmission mechanism, then rolls around through the transmission, and then undergoes magnetic separation through the magnetic separation drum. This increases the contact area between the material and the magnetic separation drum, avoids repeated magnetic separation, and improves the efficiency of magnetic separation. Furthermore, the vibration motor drives the transmission mechanism to vibrate, increasing the collision intensity between the material falling into the transmission mechanism and the mechanism, reducing the possibility of material accumulation, and allowing the material to fully pass through the magnetic separation drum for magnetic separation.

Description

Technical Field

[0001] This utility model relates to the field of mining equipment, and in particular to a magnetic separation device. Background Technology

[0002] The process of converting tailings sand into tailings powder involves steps such as slurry preparation, flotation, dewatering and washing, drying, magnetic separation, and grinding. Magnetic separation equipment is a common type of separation equipment in tailings treatment, which separates various minerals based on whether they can be attracted by magnetism.

[0003] In existing technologies, such as the dry magnetic separator for tailings disclosed in Chinese Patent Publication No. CN118237165A, there is a main shell with two support plates fixedly connected to the bottom of the shell, and a support platform fixedly connected to the bottom of the two support plates. A feed inlet is located at the top of the shell. In actual magnetic separation processes, due to the limited size of the feed inlet for tailings, the tailings are often difficult to disperse after entering the magnetic separator. This makes it difficult for the magnetic separator drum to fully separate the tailings during the rolling magnetic separation process. Furthermore, the presence of a certain amount of mud in the tailings, which has a certain moisture content, can also cause some tailings to clump together. Summary of the Invention

[0004] This invention provides a magnetic separation device, which aims to solve the problem in the prior art where tailings accumulate at the feed inlet during the tailings magnetic separation process, affecting the tailings magnetic separation effect.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0039] Refer to the accompanying drawings in the instruction manual, such as Figures 1-8 As shown, a magnetic separation device,

[0040] The device includes an outer shell 1, which is divided into a first box 11 and a second box 12. The first box 11 is fixed to the second box 12 in a horizontal direction. The side connecting the first box 11 and the second box 12 is not covered, so that the first box 11 and the second box 12 are connected and the material in the first box 11 can enter the second box 12.

[0041] Specifically, such as Figure 4 , Figure 8As shown, the magnetic separator also includes a material input structure 2, which includes a vertically arranged feed pipe 21 and a first trapezoidal funnel 22 fixed to the bottom of the feed pipe 21. The first trapezoidal funnel 22 is located inside the first housing 11. The first trapezoidal funnel 22 is wider at the top and narrower at the bottom, allowing material to diffuse outwards after passing through it, preventing material accumulation. The feed pipe 21 extends beyond the top of the first housing 11. A first flange 23 is fixedly installed on the outer ring of the top of the feed pipe 21. An external feeding pipe can be connected to the feed pipe 21 via the first flange 23. Material first passes through the external feeding pipe and then enters the first housing 11 through the feed pipe 21. This detachable connection facilitates material supply. A second flange 24 is fixedly installed at the connection between the feed pipe 21 and the top of the first housing 11 by welding. The second flange 24 can be bolted to the first housing 11, thus limiting and fixing the feed pipe 21 within the first housing 11.

[0042] Specifically, such as Figures 1-5 As shown, where Figure 2 The dashed line represents a schematic diagram of the material support plate 31 and the first base plate 34 being blocked in the side view of the transmission mechanism 3. The magnetic separator also includes a transmission mechanism 3, which is located inside the first housing 11 and below the first trapezoidal funnel 22 in the material conveying structure 2. The transmission mechanism 3 includes an inclined material support plate 31, a vertically arranged first baffle 32, a second baffle 33, a first base plate 34, and a second base plate 35. One side of the material support plate 31 is directly fixed to one side of the first base plate 34, and the other side of the material support plate 31 and the other side of the first base plate 34 are respectively fixed to the two ends of the first baffle 32, forming an angle between the material support plate 31 and the first base plate 34, and forming a right triangle with the first baffle 32. There are two second baffles 33, fixed to both sides of the material support plate 31 and the first base plate 34 respectively. Material flowing through the feed pipe 21 and the first trapezoidal funnel 22 falls onto the receiving plate 31 and collides with it. Then, on the inclined receiving plate 31, the material rolls downwards due to its own gravity. Simultaneously, second baffles 33 on both sides prevent the material from falling laterally outside the conveying mechanism 3. The second base plate 35 is located below the first base plate 34, and multiple support columns 36 are fixedly installed between the second base plate 35 and the first base plate 34.

[0043] Furthermore, such as Figure 3 As shown, multiple wavy protrusions 37 are provided on the upper surface of the material support plate 31. By providing the protrusions 37, the collision frequency and degree between the material and the material support plate 31 can be increased, thereby avoiding material aggregation and paving the way for the subsequent magnetic separation process. The wavy shape of the protrusions 37 increases their length and curvature, which is beneficial to the collision effect between the material and the protrusions 37, thereby further reducing material aggregation.

[0044] Specifically, such as Figure 4 , Figure 5 As shown, the magnetic separator also includes a vibrating motor 4. Vibrating screen springs 41 are provided on both sides of the vibrating motor 4. A connecting plate 42 is fixedly provided above the vibrating screen springs 41. A connecting stud 43 is fixedly provided in the middle of the connecting plate 42. The connecting stud 43 passes through the second base plate 35. Two nuts 44 are respectively provided at the connection between the connecting stud 43 and the second base plate 35. The two nuts 44 limit the second base plate 35, so that the second base plate 35 and the transmission mechanism 3 on it vibrate with the vibrating motor 4, which increases the collision degree of the material falling on the receiving plate 31 and further reduces the accumulation of material.

[0045] Specifically, such as Figure 6 As shown, the magnetic separation equipment also includes a magnetic separation drum 5, with a rotating shaft 51 running through its center. The rotating shaft 51 drives the magnetic separation drum 5 to rotate. The magnetic separation drum 5 is a common existing device in the field of mineral processing. The magnets inside the magnetic separation drum 5 are electromagnets, and their magnetic control is achieved by an external power supply and circuit. Both ends of the rotating shaft 51 extend outward after passing through the second housing 12, and a bearing 52 is installed between the rotating shaft 51 and the second housing 12.

[0046] The rotating shaft 51 is a stepped shaft, and a transmission component 54 is provided at one end of the rotating shaft 51. The transmission component 54 rotates synchronously with the rotating shaft 51. Optionally, the transmission component 54 and the rotating shaft 51 are connected by a key; or the transmission component 54 and the rotating shaft 51 are interference fit. A stop 53 is fixedly provided at the other end of the rotating shaft 51 to limit the rotating shaft 51 from moving excessively to the left during rotation.

[0047] Specifically, such as Figure 8 As shown, the magnetic separator also includes a support frame 7, a drive motor 8, and a transmission mechanism 9. The support frame 7 can be formed by welding and fixing multiple profiles. A mounting plate for fixing the drive motor 8 is welded onto the support frame 7. The drive motor 8 can be a servo motor. The drive motor 8 drives the transmission component 54 to rotate through the transmission mechanism 9, which in turn drives the rotating shaft 51 to rotate. A reducer can be added as needed to increase the torque output of the drive motor 8. The transmission mechanism 9 can be a transmission belt, specifically a toothed transmission belt. In this case, a driving synchronous pulley is synchronously rotated on the output shaft of the drive motor 8, and the transmission component 54 is a driven synchronous pulley. Alternatively, the transmission mechanism 9 can be a chain, with a driving sprocket synchronously rotated on the output shaft of the drive motor 8, and the transmission component 54 is a driven sprocket.

[0048] Specifically, such as Figure 7 , Figure 8As shown, the magnetic separator also includes a material output structure 6, which comprises a first discharge pipe 61 and a second discharge pipe 63 connected to the second housing 12. A second trapezoidal funnel 63 and a third trapezoidal funnel 64 are fixedly installed at the bottom of the first discharge pipe 61 and the second discharge pipe 63. Materials not adsorbed by the magnetic separator drum 5, as well as materials adsorbed by the magnetic separator drum 5, are respectively output through the first discharge pipe 61 and the second discharge pipe 63 and collected by an external collection device. The position of the material output structure 6 within the second housing 12 can be preset according to experimental and actual needs to meet different magnetic separation requirements.

[0049] Based on the above, the magnetic separation process for materials is as follows:

[0050] The material to be magnetically separated enters the first box 11 through the feed pipe 21 of the material input structure 2 and the first trapezoidal funnel 22 from the external feeding pipe, and falls onto the support plate 31 in the transmission mechanism 3. Under the action of the vibration motor 4, the material falling on the support plate 31 vibrates on the support plate 3. Due to the inclined support plate 31, the material moves downward while vibrating up and down, under the influence of its own gravity, until it leaves the support plate 31 and enters the second box 12.

[0051] The material entering the second chamber 12 is affected by the rotating magnetic separator 5. Some of the magnetically adsorbed material is adsorbed onto the magnetic separator 5, while the non-magnetically adsorbed material falls into the first discharge pipe 61 in the material output structure 6 and is collected after leaving the magnetic separator. The material adsorbed on the magnetic separator 5 falls into the second discharge pipe 62 in the material output structure 6 after the magnetic separator 5 loses its magnetism and is collected after leaving the magnetic separator, thus completing the magnetic separation process of the material.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
