Description

Technical Field

[0001] This utility model relates to the field of magnetic separation technology for mineral powder, specifically a magnetic separation and filtration device for mineral powder. Background Technology

[0002] Magnetic separation of mineral powder is a method that uses magnetic force to separate magnetic substances in mineral powder. It has broad application prospects in mineral purification, resource recovery and environmental protection. Its advantages such as high efficiency, environmental protection and strong adaptability have led to the widespread promotion and application of magnetic separation technology in the field of mineral processing.

[0003] Magnetic substances in mineral powder can be classified according to the strength of their magnetism into: strongly magnetic minerals, moderately magnetic minerals, weakly magnetic minerals, and non-magnetic minerals.

[0004] However, existing magnetic separation devices for mineral powder generally use permanent magnets as the main magnetic separator. Their magnetic force cannot be adjusted or changed, and they can only screen minerals that are magnetic and non-magnetic, but cannot screen and classify minerals with different magnetic strengths.

[0005] To solve this technical problem, this utility model proposes a magnetic separation and filtration device for mineral powder. Utility Model Content

[0006] The purpose of this invention is to provide a magnetic separation and filtration device for mineral powder to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mineral powder magnetic separation and filtration device, comprising a housing, a constraint ring at the upper end of the housing, a rotating wheel inside the constraint ring, a magnetic transmission belt at the outer end of the rotating wheel, the magnetic transmission belt comprising a magnetic layer composed of electro-permanent magnet rods, a distribution box at the side end of the constraint ring, a strong electric strip, a medium electric strip, and a weak electric strip inside the distribution box, the magnetic layer being slidably connected to the strong electric strip, the medium electric strip, and the weak electric strip, and a partition plate fixedly connected inside the housing, the partition plate dividing the inside of the housing into a strong magnetic mineral chamber, a medium magnetic mineral chamber, and a weak magnetic mineral chamber.

[0008] Preferably, a support column is fixedly connected to the lower end of the housing, a sealing shell is connected to the constraint ring side end opposite the distribution box, a rotating wheel is rotatably connected to the inner side of the sealing shell, the magnetic transmission belt includes an outer layer, the outer surface of the outer layer is smooth, the outer layer is located outside the magnetic layer and fixedly connected to it, a rubber strip is fixedly connected to the outer end of the outer layer, and the rubber strip is slidably connected to the inner wall of the constraint ring.

[0009] Preferably, a motor is fixedly connected to the side end of the rotating wheel, the magnetic transmission belt includes an inner layer, the inner layer is located inside the magnetic layer and fixedly connected thereto, the inner layer is rotatably connected to the rotating wheel, and both the outer layer and the inner layer are made of non-magnetic materials.

[0010] Preferably, the high-voltage strip, the medium-voltage strip, and the low-voltage strip all carry current, with the current of the high-voltage strip being greater than that of the medium-voltage strip, and the current of the medium-voltage strip being greater than that of the low-voltage strip.

[0011] Preferably, the medium-magnetic strip is located at the upper end of the weak magnetic mineral chamber, the weak-magnetic strip is located at the upper end of the medium magnetic mineral chamber, the strong magnetic mineral chamber is located at the side end of the medium magnetic mineral chamber, and discharge ports are provided at the lower ends of the strong magnetic mineral chamber, the medium magnetic mineral chamber, and the weak magnetic mineral chamber.

[0012] Preferably, a ash discharge pipe is fixedly connected to the side end of the constraint ring, a cleaning roller is provided inside the ash discharge pipe, the cleaning roller is in contact with the outer surface of the magnetic transmission belt, and a motor is fixedly connected to the side end of the cleaning roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, strong, medium, and weak electric strips are arranged on the side of the magnetic transmission belt. Based on the principle that the greater the current passed through an electro-permanent magnet, the magnetic force of the magnetic transmission belt is the greatest compared to the medium and weak electric strips. The magnetic force of the magnetic transmission belt in the strong electric strip section is also the greatest compared to the medium and weak electric strip sections. By designing the magnitude of the current, minerals with different magnetic properties can be collected into different mineral chambers. This solves the problem that existing mineral powder magnetic separation devices can only screen minerals with magnetic and non-magnetic properties, and cannot screen and classify minerals with different magnetic intensities.

[0015] In this invention, a cleaning roller is provided. Starting the motor at its side can drive the cleaning roller to rotate, thereby cleaning the outer surface of the magnetic transmission belt, removing the minerals adhering to its surface and pushing them into the ash discharge pipe. This cleans the magnetic transmission belt and prevents excessive mineral powder from adhering to its outer end, which would affect its magnetic efficiency and quality. Attached Figure Description

Detailed Implementation

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a magnetic separation and filtration device for mineral powder, including a housing 1, a constraint ring 2 at the upper end of the housing 1, a rotating wheel 3 inside the constraint ring 2, a motor fixedly connected to the side end of the rotating wheel 3, and a magnetic transmission belt 4 at the outer end of the rotating wheel 3. The rotating wheel 3 can drive the magnetic transmission belt 4 to rotate, thereby moving the mineral powder to be screened. The magnetic transmission belt 4 includes a magnetic layer 5, which is composed of electro-permanent magnet rods 6. When the electro-permanent magnet rods 6 are energized, they will generate magnetic force, and the greater the input current, the greater the magnetic force. The magnetic transmission belt 4 includes an outer layer 15, the outer surface of which is smooth, thereby reducing the adhesion of mineral powder. The outer layer 15 is located at the outer end of the magnetic layer 5 and is fixedly connected to it. A rubber strip 16 is fixedly connected to the outer end of the outer layer 15. The rubber strip 16 is slidably connected to the inner wall of the constraint ring 2, so as to prevent the mineral powder on the magnetic transmission belt 4 from entering the constraint ring 2. The magnetic transmission belt 4 includes an inner layer 17, which is located at the inner end of the magnetic layer 5 and is fixedly connected to it. The inner layer 17 is rotatably connected to the rotating wheel 3. The inner layer 17 is used to protect the magnetic layer 5 and prevent it from being damaged by the rotating wheel 3. The outer layer 15 and the inner layer 17 are both made of non-magnetic materials, so the magnetic force generated by the magnetic layer 5 will not affect the outer layer 15 and the inner layer 17, thereby better screening the mineral powder.

[0023] A distribution box 7 is provided on the side end of the constraint ring 2. A sealing shell is connected to the side end of the constraint ring 2 opposite to the distribution box 7. A rotating wheel 3 is rotatably connected inside the sealing shell. A high-voltage strip 8, a medium-voltage strip 9, and a low-voltage strip 10 are provided inside the distribution box 7. The distribution box 7 inputs current to the high-voltage strip 8, the medium-voltage strip 9, and the low-voltage strip 10. The current of the high-voltage strip 8 is greater than the current of the medium-voltage strip 9, and the current of the medium-voltage strip 9 is greater than the current of the low-voltage strip 10. The magnetic layer 5 is slidably connected to the high-voltage strip 8, the medium-voltage strip 9, and the low-voltage strip 10. Thus, the permanent magnet rod 6 in contact with the strips will have magnetic force, and its magnetic force will change depending on the strip it is in contact with.

[0024] A partition plate 11 is fixedly connected inside the housing 1, dividing the housing 1 into a strong magnetic mineral chamber 12, a medium magnetic mineral chamber 13, and a weak magnetic mineral chamber 14. A medium electric strip 9 is located at the upper end of the weak magnetic mineral chamber 14, a weak electric strip 10 is located at the upper end of the medium magnetic mineral chamber 13, and the strong magnetic mineral chamber 12 is located at the side end of the medium magnetic mineral chamber 13. Discharge ports are provided at the lower ends of the strong magnetic mineral chamber 12, the medium magnetic mineral chamber 13, and the weak magnetic mineral chamber 14. A support column is fixedly connected to the lower end of the housing 1. The support column is used to support and fix the device and also provides discharge space for the discharge ports of each mineral chamber.

[0025] A dust discharge pipe 18 is fixedly connected to the side end of the constraint ring 2. A cleaning roller 19 is installed inside the dust discharge pipe 18. The cleaning roller 19 is in contact with the outer surface of the magnetic transmission belt 4. A motor is fixedly connected to the side end of the cleaning roller 19. The motor can drive the cleaning roller 19 to rotate, thereby cleaning the outer surface of the magnetic transmission belt 4. The dust that is cleaned will fly into the dust discharge pipe 18 under the action of the centrifugal force of the rotating cleaning roller 19, and finally be discharged from the dust discharge pipe 18.

[0026] The rotating wheel 3 is driven to rotate by the motor on its side, which in turn drives the magnetic transmission belt 4 to rotate, evenly distributing the mineral powder onto the magnetic transmission belt 4. The electro-permanent magnet rod 6 of the strong electric bar 8 section has magnetic force that can attract all magnetic minerals onto the magnetic transmission belt 4. As the magnetic transmission belt 4 rotates, non-magnetic minerals will fall directly from the side of the magnetic transmission belt 4 under the action of gravity, while magnetic minerals will be attracted to the magnetic transmission belt 4 and continue to move with it. The electro-permanent magnet rod 6 located in the middle electric bar 9 section changes current. The current decreases again, weakening the magnetic force. At this point, the weakly magnetic minerals will fall and fall into the weakly magnetic mineral chamber 14. The current in the electro-permanent magnet rod 6 located in the weak current strip 10 decreases again, and the magnetic force weakens again. At this point, the medium magnetic minerals will fall and fall into the medium magnetic mineral chamber 13. Then, the electro-permanent magnet rod 6 that leaves the weak current strip 10 will no longer be energized, thus losing its magnetic force. As a result, all the remaining magnetic minerals on the magnetic transmission belt 4 will fall and fall into the strong magnetic mineral chamber 12. In this way, the mineral powder can be classified and collected according to the strength of its magnetic properties.
