Description

Technical Field

[0001] This utility model relates to the field of tailing magnetic separator technology, and more specifically, to a tailing magnetic separator for ore processing. Background Technology

[0002] Iron ore is a very important mineral material. In order to extract iron ore from the ore during mining, magnetic separators are used to separate the iron ore. The magnetic properties are used to separate the iron ore impurities from the ore, and then the ore can be recycled.

[0003] A search revealed that invention patent CN115672547A discloses an ore magnetic separator, comprising a housing. A crushing box is located on the upper part of one side of the housing, and ore outlet and iron ore outlet 1 are respectively located on the lower two sides of the housing. An iron ore outlet 2 is located on the lower part of the other side of the housing. A primary magnetic separation component is located inside one side of the housing. A conveying component is located inside the housing next to the primary magnetic separation component, and a feeding component is located above the conveying component inside the housing. A feeding drive component corresponding to the feeding component is located on the upper part of the housing. This ore magnetic separator, by setting up a primary magnetic separation component and a secondary magnetic separation component, can perform dual magnetic separation of the ore. Compared with traditional magnetic separators, this magnetic separator achieves a more thorough magnetic separation effect on the ore, reducing waste. However, the aforementioned patent has the following shortcomings: Although the combination of the magnetic block and the roller can perform some screening of iron ore, there is a certain space between the roller and the conveyor belt, which causes some ordinary ore to fall onto the guide plate. Furthermore, when using an electromagnetic plate to screen iron ore, the uncontrollable shape of the iron ore can lead to the inclusion of ordinary ore, affecting the screening quality. When the baffle moves downwards, ore accumulates on the conveyor belt. If the baffle does not obstruct the ore, the accumulated ore will fall onto the electromagnetic plate for screening all at once, also affecting the ore screening quality. Therefore, we propose a tailings magnetic separator for ore processing. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a tailing magnetic separator for ore processing.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A tailings magnetic separator for ore processing includes a housing with discharge troughs on both sides. A discharge hopper is fixedly fitted to the bottom of the housing. Receiving boxes are fixedly connected to both sides of the housing, with the bottom ends of the two receiving boxes connected to the top of the inner cavity of the discharge hopper. Two conveyor frames are fixedly connected to one end of the housing. Conveying rollers are rotatably connected between the two conveyor frames and the inner cavity of the housing. A conveyor belt is driven between the two conveying rollers. A first motor is fixedly installed on the side of the housing, with its output shaft connected to one end of a conveyor roller shaft. A crushing mechanism is provided on the top of the housing. A vibration mechanism is provided in the inner cavity of the housing. A second motor is fixedly installed on the top surface of the housing, with its output shaft extending into the inner cavity of the housing and fixedly connected to a rotating disk. The two sides of the rotating disk extend through the discharge troughs to the top of the receiving boxes. Two arc-shaped electromagnets are fixedly installed on the top surface of the inner cavity of the housing and the inner cavity of the rotating disk, with the bottom surfaces of the two arc-shaped electromagnets fitting against the bottom surface of the inner cavity of the rotating disk.

[0007] As a preferred embodiment of this utility model, the vibration mechanism includes a mounting base fixedly connected to the inner cavity of the box, the mounting base penetrating the inner side of the conveyor belt, a plurality of dual-axis motors fixedly mounted on the top surface of the mounting base, two output shafts of the dual-axis motors respectively fixedly connected to rotating rods, and a plurality of push rods fixedly connected to the side of the rotating rods.

[0008] As a preferred embodiment of this utility model, the crushing mechanism includes a crushing box fixedly sleeved on the top of the housing, two crushing rollers rotatably connected to the inner cavity of the crushing box, and two third motors fixedly installed on the side of the crushing box. The output shafts of the two third motors are respectively connected to one end of the rotating shaft of the two crushing rollers.

[0009] As a preferred embodiment of this utility model, a control panel is fixedly installed on the bottom surface of the box.

[0010] In a preferred embodiment of this utility model, the side of the conveyor belt is fitted to the inner wall of the box.

[0011] As a preferred embodiment of this utility model, the bottom surface of the box is fixedly connected with multiple support legs.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) In this utility model, a conveyor belt is used to transport the ore, and a second motor is used to drive the rotating disk to rotate. When the ore on the conveyor belt moves to the bottom of the arc electromagnet, the attraction force of the arc electromagnet is used to attract the iron ore in the ore to the bottom surface of the rotating disk. When the rotating disk rotates, it drives the iron ore below the rotating disk to rotate synchronously. When the iron ore below the rotating disk moves to the top of the receiving box, the iron ore falls into the receiving box and is discharged from the discharge hopper, thus realizing the function of continuous magnetic separation of iron ore in the ore. At the same time, the two arc electromagnets can perform two magnetic separations on the ore to ensure the quality of the magnetic separation of the ore.

[0014] (2) In this utility model, by using the combination of a dual-shaft motor, a rotating rod and a push rod, when the conveyor belt transports the ore, the dual-shaft motor drives the rotating rod and the push rod to rotate, and the push rod pushes the upper part of the conveyor belt to vibrate, so as to disperse the ore transported on the conveyor belt and ensure the quality of magnetic separation of the ore.

[0026] Example:

[0027] Please see Figure 1-6A tailings magnetic separator for ore processing includes a housing 1, with discharge chutes 2 on both sides of the housing 1. A discharge hopper 3 is fixedly fitted to the bottom of the housing 1. Receiving boxes 4 are fixedly connected to both sides of the housing 1, with the bottom ends of the two receiving boxes 4 connected to the top of the inner cavity of the discharge hopper 3. Two conveyor frames 7 are fixedly connected to one end of the housing 1. Conveying rollers 5 are rotatably connected between the two conveyor frames 7 and the inner cavity of the housing 1. A conveyor belt 6 is drively connected between the two conveyor rollers 5. A first motor 8 is fixedly installed on the side of the housing 1. The first motor 8... The output shaft is connected to one end of the shaft of a conveying roller 5. A crushing mechanism 11 is provided on the top of the box 1. A vibration mechanism 9 is provided in the inner cavity of the box 1. A second motor 12 is fixedly installed on the top surface of the box 1. The output shaft of the second motor 12 extends into the inner cavity of the box 1 and is fixedly connected to a rotating disk 13. The two sides of the rotating disk 13 extend through the discharge chute 2 to the top of the receiving box 4. Two arc-shaped electromagnets 14 are fixedly installed on the top surface of the inner cavity of the box 1 and the inner cavity of the rotating disk 13. The bottom surfaces of the two arc-shaped electromagnets 14 are in contact with the bottom surface of the inner cavity of the rotating disk 13.

[0028] In this embodiment, the attraction of the arc-shaped electromagnet 14 is used to make the iron ore adhere to the bottom surface of the rotating disk 13. At the same time, when the second motor 12 drives the rotating disk 13 to rotate, the iron ore below the rotating disk 13 rotates synchronously. When the iron ore below the rotating disk 13 moves to the top of the receiving box 4, the area above the rotating disk 13 is in the area without the arc-shaped electromagnet 14, and the iron ore falls into the receiving box 4.

[0029] For details, please refer to Figure 2 and Figure 6 The vibration mechanism 9 includes a mounting base 10 fixedly connected to the inner cavity of the housing 1. The mounting base 10 passes through the inner side of the conveyor belt 6. Multiple dual-axis motors 15 are fixedly installed on the top surface of the mounting base 10. Two output shafts of the dual-axis motors 15 are respectively fixedly connected to rotating rods 16. Multiple push rods 17 are fixedly connected to the side of the rotating rods 16.

[0030] In this embodiment, a dual-axis motor 15 drives the rotating rod 16 and the push rod 17 to rotate. The push rod 17 can push the top of the conveyor belt 6 to vibrate and disperse the ore conveyed on the conveyor belt 6, so as to ensure that the arc electromagnet 14 can adsorb and screen the iron ore in the ore.

[0031] For details, please refer to Figure 1 and Figure 5 The crushing mechanism 11 includes a crushing box 20 fixedly sleeved on the top of the box body 1. Two crushing rollers 21 are rotatably connected to the inner cavity of the crushing box 20. Two third motors 22 are fixedly installed on the side of the crushing box 20. The output shafts of the two third motors 22 are respectively connected to one end of the rotating shaft of the two crushing rollers 21.

[0032] In this embodiment, the end faces of the two crushing rollers 21 are in contact with the inner wall of the crushing box 20 to ensure that the two crushing rollers 21 can crush the ore.

[0033] For details, please refer to Figure 1 A control panel 19 is fixedly installed on the bottom surface of the housing 1.

[0034] In this embodiment, the control panel 19 is electrically connected to the arc electromagnet 14, the first motor 8, the second motor 12, and the third motor 22, respectively, and the control panel 19 is used to control the arc electromagnet 14, the first motor 8, the second motor 12, and the third motor 22.

[0035] For details, please refer to Figure 1 and Figure 2 The side of the conveyor belt 6 is in contact with the inner wall of the box 1.

[0036] In this embodiment, the inner wall of the box 1 is used to limit the side of the conveyor belt 6 to prevent the ore from falling off the side of the conveyor belt 6.

[0037] For details, please refer to Figure 1 The bottom surface of the box 1 is fixedly connected with multiple support legs 18.

[0038] In this embodiment, multiple support legs 18 are used to support the box 1.

[0039] Working principle: In operation, firstly, the two third motors 22 are started, driving the two crushing rollers 21 to move inward. Then, the first motor 8 is started, driving one conveyor roller 5 to rotate clockwise. The conveyor roller 5 then drives the conveyor belt 6 to rotate clockwise. Additionally, the second motor 12 is started, driving the rotating disk 13 to rotate. The ore to be magnetically separated is then placed into the inner cavity of the crushing box 20. The two crushing rollers 21 crush the ore, and the crushed ore falls onto the conveyor belt 6. The conveyor belt 6 moves the ore. Next, the arc-shaped electromagnet 14 is energized, causing its bottom surface to generate magnetic attraction. When the ore on the conveyor belt 6 moves below the arc-shaped electromagnet 14, the iron ore in the ore is attracted to the area below the arc-shaped electromagnet 14. On the bottom surface of the rotating disk 13, as the rotating disk 13 rotates, the iron ore below the rotating disk 13 moves synchronously. When the iron ore below the rotating disk 13 moves above the receiving box 4, the area above the rotating disk 13 is without the arc electromagnet 14. The iron ore falls into the receiving box 4. At the same time, the rotating disk 13 below the arc electromagnet 14 continues to attract iron ore. Finally, multiple dual-shaft motors 15 are started to drive multiple rotating rods 16 and multiple push rods 17. The push rods 17 push the upper part of the conveyor belt 6, causing the ore on the conveyor belt 6 to vibrate, so that the ore is dispersed, and the iron ore in the ore can be attracted to the rotating disk 13 below the arc electromagnet 14.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
