Description

Technical Field

[0001] The utility model belongs to the technical field of ore magnetic separation, and in particular relates to a rotating spiral magnetic field magnetic separator used for ore mining. Background Art

[0002] A magnetic separator is a device that uses magnetic force to separate magnetic and non-magnetic components from a material. It is widely used in mining, recycling, chemicals, food processing, and other industries requiring material separation. It is particularly important in the mining of ores containing magnetic minerals.

[0003] For example, the patent with the patent publication number CN2825113Y and the publication date of October 11, 2006, discloses a concentration magnetic separator. In the traditional drum magnetic separator, the ore passes through the material box quickly. The short process from the inlet to the outlet causes the ore to stay in the magnetic field for a short time. Some magnetic particles may not have enough time to be completely attracted by the magnetic force and effectively separated, which will reduce the magnetic separation efficiency and concentrate grade.

[0004] In view of the shortcomings of the above-mentioned prior art, a rotating spiral magnetic field magnetic separator for ore mining is designed to overcome the shortcomings of the prior art and improve the magnetic separation path and time. Utility Model Content

[0007] Preferably, the adsorption component includes a second magnetic system, which is connected to the upper left part of the frame, and the magnetic angle notch of the second magnetic system faces away from the magnetic angle notch of the first magnetic system. The upper left part of the frame is rotatably provided with a second transmission shaft driven by an external power source, and the second transmission shaft is connected to a second roller surrounding the second magnetic system, and the second roller is close to the magnetic angle notch of the first magnetic system.

[0008] Preferably, a servo motor is also included. The servo motor is installed on the frame. The output shaft of the servo motor is connected to the transmission shaft one. The servo motor drives the transmission shaft one instead of the external power source. The rear end of the transmission shaft one and the rear end of the transmission shaft two are both connected with spur gears. The two spur gears are meshed with each other, and the transmission of the spur gears replaces the external power source to drive the transmission shaft two.

[0009] Preferably, a spray pipe is further included. The upper right part of the frame is provided with the spray pipe, and the spray port of the spray pipe faces the drum one.

[0010] Preferably, a support block is further included. The support block is provided on the upper left part of the frame.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0023] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0024] A rotating spiral magnetic field separator for ore mining, such as Figure 1-Figure 5As shown, it includes a frame 1, a material box 2 is connected to the frame 1, and the front and rear ends of the material box 2 respectively have an upward feeding port 20 and a downward discharging port 21, the ore to be magnetically separated is added to the material box 2 through the feeding port 20, and the ore in the material box 2 that has been magnetically separated is discharged from the discharging port 21, and a magnetic system 31 is connected to the material box 2, and a transmission shaft 32 driven by an external power source is provided on the material box 2, and a roller 33 surrounding the magnetic system 31 is connected to the transmission shaft 32, and the roller 33 is driven to rotate by the transmission shaft 32, so that the magnetic particles in the ore in the material box 2 are magnetically separated and adsorbed on the roller 33, and the outer side of the roller 33 is connected to a spiral blade 34 that contacts and cooperates with the inner side of the material box 2, and the rotation of the roller 33 will drive the spiral blade 34 to rotate, and the spiral blade 34 is suitable for transporting the ore at the feeding port 20 of the material box 2 backward to the discharging port 21 of the material box 2 by rotation, so as to increase the moving distance of the ore and avoid The phenomenon that the ore is discharged immediately after being added to the material box 2 occurs, which increases the magnetic separation distance of the ore and increases the time the ore stays in the magnetic field, so that there is enough time for the magnetic particles in the ore to be completely attracted by the magnetic force and effectively separated, eliminating the steps of repeated magnetic separation for two or more times, ensuring the magnetic separation efficiency and concentrate grade, and an opening is opened on the upper side of the middle part of the material box 2 between the feed port 20 and the discharge port 21, and the magnetic angle notch of the magnetic system 31 faces the opening of the material box 2. An adsorption component for adsorbing magnetic particles is provided on the frame 1, and the adsorption component is close to the magnetic angle notch of the magnetic system 31. When the roller 33 drives the magnetically attracted magnetic particles to rotate to the magnetic angle notch of the magnetic system 31, the magnetic particles will gradually separate from the roller 33 due to the weakening of the magnetism. At this time, the magnetic particles are also located at the opening of the material box 2, so that the adsorption component can be controlled to adsorb the detached magnetic particles from the opening of the material box 2, thereby completing the magnetic separation operation.

[0025] like Figure 2 and Figure 5 As shown, the adsorption component includes a magnetic system 41, and the upper left part of the frame 1 is connected to the magnetic system 41. The magnetic angle notch of the magnetic system 41 is facing away from the magnetic angle notch of the magnetic system 31. The upper left part of the frame 1 is rotatably provided with a transmission shaft 42 driven by an external power source. The transmission shaft 42 is connected to a roller 43 surrounding the magnetic system 41. The roller 43 is close to the magnetic angle notch of the magnetic system 31. The magnetic system 41 will magnetically attract the magnetic particles that have separated from the roller 33 to the roller 43 through the opening on the material box 2. When the roller 43 drives the magnetically attracted magnetic particles to rotate to the magnetic angle notch of the magnetic system 41, the magnetically selected magnetic particles are completely discharged, thereby avoiding the accidental adsorption of non-magnetic particles on the roller 33 by magnetic attraction.

[0026] like Figure 4 and Figure 6As shown, a servo motor 51 is also included. The servo motor 51 is installed on the frame 1. The output shaft of the servo motor 51 is connected to the transmission shaft 1 32. The servo motor 51 drives the transmission shaft 1 32 instead of the external power source. The rear end of the transmission shaft 1 32 and the rear end of the transmission shaft 2 42 are both connected with a spur gear 52. The two spur gears 52 are meshed with each other. The transmission of the spur gear 52 replaces the external power source to drive the transmission shaft 2 42. In this way, when the roller 1 33 rotates clockwise, the roller 2 43 will automatically and synchronously rotate counterclockwise.

[0027] like Figure 1 As shown, a spray pipe 7 is also included. The spray pipe 7 is provided on the upper right part of the frame 1. The spray port of the spray pipe 7 faces the drum 33. The spray pipe 7 sprays water onto the drum 33, thereby enabling water washing and magnetic separation operations.

[0028] like Figure 1 and Figure 7 As shown, a support block 61 is provided on the upper left part of the frame 1. A pressure roller 62 is rotatably provided on the support block 61 and is located directly above the second roller 43. A gap is left between the pressure roller 62 and the second roller 43 for the magnetic particles to pass through. The pressure roller 62 will press away the magnetic particles magnetically attracted on the second roller 43 to filter out the moisture.

[0029] like Figure 1 and Figure 7 As shown, a screw 63 is also included. The support block 61 is slidably arranged on the frame 1. The frame 1 is rotatably provided with a screw 63 threadedly connected to the support block 61. The screw 63 is rotated to drive the support block 61 to drive the pressure roller 62 to rise and fall, thereby adjusting the gap between the pressure roller 62 and the roller 43, thereby adapting to the operation of filtering out moisture from magnetic particles of different sizes, and having strong adaptability.

[0030] Obviously, the embodiments described above are only part of the embodiments of the present invention, rather than all of the embodiments. They only express the preferred implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention.

[0031] It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, they can also make several modifications, increases and decreases in quantity, improvements and substitutions. Therefore, based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
