Description

Technical Field

[0001] The invention relates to the technical field of magnetic separation equipment, in particular to a medium immersion type magnetic separator. Background Art

[0002] Wet magnetic separators are commonly used iron ore equipment (iron ore magnetic separators) and manganese ore equipment (manganese ore magnetic separators). They are mainstream strong magnetic separators and mineral processing equipment. Wet permanent magnetic drum magnetic separators: Wet permanent magnetic drum magnetic separators are a type of magnetic separator commonly used in iron ore beneficiation plants. They are suitable for the separation of strong magnetic minerals. Wet permanent magnetic drum magnetic separators are divided into three types according to the tank structure: downstream, countercurrent, and semi-countercurrent. In addition to being used as separation equipment in magnetic separation plants, wet permanent magnetic drum magnetic separators are also used as pre-filtration concentration equipment to replace magnetic dehydration tanks. There are many types of strong magnetic field magnetic separators.

[0003] However, when the existing vertical wet magnetic separator completes the magnetic separation process, the slurry generally flows directly along the slurry trough through the magnetic separator and then completes the magnetic separation. However, the slurry has a higher flow rate under the action of gravity, and after the medium component completes the magnetic separation in the slurry, it needs to be moved outside the magnetic field to perform iron removal operations. Therefore, a large amount of slurry is directly discharged without undergoing magnetic separation, thereby causing the undesirable production phenomenon of low magnetic separation efficiency of the magnetic separator. Summary of the invention

[0004] The object of the present invention is to provide a medium immersion magnetic separator, which can keep the medium component immersed in the slurry so as to improve the magnetic separation efficiency and magnetic separation effect of the medium component, and can timely adjust the flow of the slurry through the flow regulating component, and has the advantage of low production cost.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a medium immersion magnetic separator, comprising a frame, a magnetic component is provided on the frame, a slurry groove is provided in the magnetic component for allowing the slurry to flow out naturally, a medium component that can reciprocate in the slurry groove is passed through the slurry groove, a flushing area is provided on the side of the slurry groove for flushing the medium component, and a flow regulating component is connected to the slurry groove for controlling the outflow of the slurry and keeping the medium component immersed in the slurry.

[0006] By adopting the above technical solution, when the flow regulating component is in an open state, the slurry after magnetic separation can flow out of the flow regulating component; when the flow regulating component is in a closed state, the flow regulating component can fill the inside of the slurry tank with slurry, so that the medium component can be kept immersed in the slurry, so as to improve the magnetic separation efficiency and magnetic separation effect of the medium component. The user can also adjust the flow of the slurry in time through the flow regulating component, so that the slurry does not flow too fast while the flow rate is kept flowing out, so as to improve the magnetic separation efficiency and adjustability of the equipment.

[0007] A further configuration of the present invention is that the flow regulating assembly includes a first flow regulating plate fixed in the slurry groove, and a second flow regulating plate that can slide relative to the first flow regulating plate, the first flow regulating plate is provided with a plurality of first through holes connected to the slurry groove, the second flow regulating plate is provided with a plurality of second through holes that can be connected to the first through holes, and when the second flow regulating plate slides relative to the first flow regulating plate, the first through holes and the second through holes are connected in an interlaced manner.

[0008] A further configuration of the present invention is that a slide groove is provided in the slurry groove and is adjacent to the side of the first flow regulating plate, and a first opening connected to the second through hole is provided on the slide groove; the first flow regulating plate is fixedly provided on the notch of the slurry groove, and the second flow regulating plate is slidably connected in the slide groove.

[0009] By adopting the above technical scheme, since there is a spacing between two adjacent second through holes, when the second flow regulating plate is moved, the spacing will control the flow degree of the first through hole as the second flow regulating plate moves, thereby realizing the flow regulation function of the slurry; and the flow regulating component of this scheme is designed for magnetic separation equipment, and the flow regulating component of this scheme can select the first flow regulating plate and the second flow regulating plate of different areas according to the area of ​​the slurry outlet of the slurry trough, and the scheme has a simple structure, is easy to process and produce, and has low processing cost and good economic benefits; secondly, the scheme can realize the slurry flow regulation only by moving the second flow regulating plate, and does not need to involve too many other complex structures, which can effectively reduce the production and manufacturing costs of the equipment.

[0010] According to a further configuration of the present invention, a spacing between two adjacent first through holes is smaller than a spacing between two adjacent second through holes.

[0011] By adopting the above technical solution, the second flow regulating plate can completely close the first through hole on the first flow regulating plate, so that the slurry stays in the slurry groove, thereby facilitating the improvement of the adjustment range of the flow regulating component.

[0012] According to a further configuration of the present invention, a first linear drive device is disposed on the frame, and a movable end of the first linear drive device is connected to the second flow regulating plate.

[0013] By adopting the above technical solution, the relative position of the second flow regulating plate and the first flow regulating plate is controlled by the first linear drive device, so as to improve the automation and accuracy of flow control.

[0014] According to a further configuration of the present invention, the frame is provided with a pulp inlet pipe connected to the pulp tank input end, and a pulp outlet pipe connected to the pulp tank output end; the flushing area is provided with a nozzle for flushing minerals on the medium component, and a collection plate for collecting flushing products.

[0015] According to a further configuration of the present invention, the number of the magnetic members is at least two, and a second linear drive device is provided between two adjacent magnetic members, a fixed end of the second linear drive device is provided on the frame, and a movable end of the second linear drive device is simultaneously connected to two adjacent medium components.

[0016] By adopting the above technical solution, two adjacent magnetic members can extend or retract the medium assembly through the same second linear drive device, so as to improve the utilization rate of the second linear drive device and further reduce the production and manufacturing costs of the device.

[0017] According to a further configuration of the present invention, the number of the flushing zones is at least two and the flushing zones are respectively arranged on both sides of the slurry tank along the axial direction of movement of the medium component.

[0018] According to a further configuration of the present invention, along the moving axis of the medium component, the axial length of the medium component is greater than the axial length of the magnetic component.

[0019] According to a further configuration of the present invention, a guide rail group extending along the moving axis of the medium component and passing through the magnetic member is disposed on the frame, and the medium component is slidably connected to the guide rail group via a slider.

[0020] By adopting the above technical solution, since the axial length of the medium component is greater than the axial length of the magnetic part, a part of the medium component can always be located inside the magnetic part (i.e., a part of the medium component is located inside the magnetic part for magnetic separation), while the other part is located in the cleaning area for cleaning, so that the medium component can always be in the working state of magnetic separation and cleaning, so as to improve the magnetic separation efficiency of the slurry. At least two flushing areas can facilitate further improving the magnetic separation efficiency.

[0021] First, the first linear drive device moves the second flow regulating plate until it is in a closed state with the first flow regulating plate, and then the slurry to be magnetically separated is input into the slurry tank through the slurry inlet pipe until the medium component is completely immersed in the slurry. At this time, the medium component completes magnetic separation under the action of the magnetic field of the magnetic component; then, the second linear drive device drives the first part of the medium component to move to the nearest flushing area, and then, under the action of the nozzle, a large amount of minerals and water attached to the medium component fall into the collection plate, and at the same time, the second part of the medium component also enters the slurry tank for magnetic separation; similarly, the second linear drive device then drives the second part of the medium component to move to another flushing area and perform a flushing process, and at the same time, the first part of the medium component also enters the slurry tank again for magnetic separation, and the above actions are repeated in this way, so that the device can maintain magnetic separation action; during the magnetic separation process, the user can adjust the flow rate of the slurry by adjusting the flow regulating component according to actual needs, so as to improve the magnetic separation efficiency of the equipment.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. The medium components can be kept immersed in the slurry to improve the magnetic separation efficiency and effect of the medium components;

[0024] 2. The flow rate of the slurry can be adjusted in time through the flow regulating component, and the magnetic separation efficiency and adjustability of the equipment can be improved;

[0025] 3. The production cost of this equipment is low and has good economic benefits;

[0026] 4. The medium components can be kept in the working state of magnetic separation and cleaning to improve the magnetic separation efficiency of the slurry.

[0027] In general, the present invention can keep the medium component immersed in the slurry, so as to improve the magnetic separation efficiency and magnetic separation effect of the medium component, and the flow rate of the slurry can be timely adjusted by the flow regulating component, and the production cost is low.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0036] Embodiment 1:

[0037] A medium immersion magnetic separator, such as Figures 1 to 5 As shown, the machine comprises a frame 1, on which a magnetic component 2 is provided, in which a slurry groove 3 is provided for allowing the slurry to flow out naturally, in which a medium component 4 which can reciprocate in the slurry groove 3 is passed, a flushing area 5 for flushing the medium component 4 is provided on the side of the slurry groove 3, and in which a flow regulating component 6 which keeps the medium component 4 immersed in the slurry is connected.

[0038] The slurry tank 3 includes a slurry inlet and a slurry outlet, and the slurry outlet and the slurry inlet are arranged in the vertical direction to enable the slurry to flow naturally downward along the inner wall of the slurry tank 3 under the action of gravity, and the flow regulating component 6 is arranged on the slurry outlet. In this embodiment, the magnetic component 2 can be a magnetic field composed of two permanent magnets or a magnetic field composed of two electromagnets. The magnetic component 2 is two plate-shaped permanent magnets or electromagnets with a spacing in the middle, and the slurry tank 3 is arranged within the spacing, the slurry inlet is located at the top of the magnetic component 2, the slurry outlet is located at the bottom of the magnetic component 2, and the medium component 4 is located on both sides of the horizontal opening of the magnetic component 2.

[0039] By adopting the above technical solution, when the flow regulating component 6 is in an open state, the slurry after magnetic separation can flow out of the flow regulating component 6; when the flow regulating component 6 is in a closed state, the flow regulating component 6 can allow the slurry to fill the inside of the slurry tank 3, so that the medium component 4 can be kept immersed in the slurry, so as to improve the magnetic separation efficiency and magnetic separation effect of the medium component 4. The user can also adjust the flow rate of the slurry in time through the flow regulating component 6, so that the slurry does not flow too fast while the flow rate is kept flowing out, so as to improve the magnetic separation efficiency and adjustability of the equipment.

[0040] like Figure 4 and Figure 5 As shown, the flow regulating assembly 6 includes a first flow regulating plate 61 fixed in the slurry tank 3, and a second flow regulating plate 62 that can slide relative to the first flow regulating plate 61. The first flow regulating plate 61 is provided with a plurality of first through holes 7 that are connected to the slurry tank 3, and the second flow regulating plate 62 is provided with a plurality of second through holes 8 that can be connected to the first through holes 7. When the second flow regulating plate 62 slides relative to the first flow regulating plate 61, the first through holes 7 and the second through holes 8 are connected in an alternating manner.

[0041] In this embodiment, both the first through hole 7 and the second through hole 8 are keyway-type through holes. Figure 4 The medium component 4 is omitted in the figure, see Figure 6 .

[0042] A slide groove 9 is provided in the slurry groove 3 and is adjacent to the first flow regulating plate 61. The slide groove 9 is provided with a first opening 10 which is connected to the second through hole 8. The first flow regulating plate 61 is fixedly provided on the notch of the slurry groove 3, and the second flow regulating plate 62 is slidably connected in the slide groove 9.

[0043] By adopting the above technical scheme, since there is a spacing between two adjacent second through holes 8, when the second flow regulating plate 62 is moved, the spacing will control the flow degree of the first through hole 7 as the second flow regulating plate 62 moves, thereby realizing the flow regulation function of the slurry; and the flow regulating component 6 of this scheme is designed for magnetic separation equipment. The flow regulating component 6 of this scheme can select the first flow regulating plate 61 and the second flow regulating plate 62 of different areas according to the area of ​​the slurry outlet of the slurry tank 3, and the scheme has a simple structure, is easy to process and produce, and has low processing cost and good economic benefits; secondly, the scheme can realize the slurry flow regulation only by moving the second flow regulating plate 62, and does not need to involve too many other complex structures, which can effectively reduce the production and manufacturing costs of the equipment.

[0044] The spacing between two adjacent first through holes 7 is smaller than the spacing between two adjacent second through holes 8. By adopting the above technical solution, the second flow regulating plate 62 can completely close the first through holes 7 on the first flow regulating plate 61, so that the slurry stays in the slurry tank 3, thereby facilitating the improvement of the adjustment range of the flow regulating component 6.

[0045] The frame 1 is provided with a first linear drive device 11, and the movable end of the first linear drive device 11 is connected to the second flow regulating plate 62. By adopting the above technical solution, the relative position of the second flow regulating plate 62 and the first flow regulating plate 61 is controlled by the first linear drive device 11, so as to improve the automation and accuracy of flow control.

[0046] The frame 1 is provided with a slurry inlet pipe 12 connected to the input end of the slurry tank 3, and a slurry outlet pipe 13 connected to the output end of the slurry tank 3; the flushing area 5 is provided with a nozzle 14 for flushing the minerals on the medium component 4, and a collection plate 51 for collecting the flushed product. The number of magnetic parts 2 is at least two, and a second linear drive device 16 is provided between two adjacent magnetic parts 2, the fixed end of the second linear drive device 16 is provided on the frame 1, and the movable end of the second linear drive device 16 is connected to two adjacent medium components 4 at the same time. By adopting the above technical solution, two adjacent magnetic parts 2 can be extended into or extended out of the medium component 4 through the same second linear drive device 16, so as to improve the utilization rate of the second linear drive device 16, thereby facilitating the reduction of the production and manufacturing costs of the device.

[0047] There are at least two flushing zones, which are respectively arranged on both sides of the slurry tank 3 along the moving axial direction of the medium component 4. Along the moving axial direction of the medium component 4, the axial length of the medium component 4 is greater than the axial length of the magnetic component 2. The frame 1 is provided with a guide rail group 17 extending along the moving axial direction of the medium component 4 and passing through the magnetic component 2, and the medium component 4 is slidably connected to the guide rail group 17 through a slider 18.

[0048] By adopting the above technical solution, since the axial length of the medium component 4 is greater than the axial length of the magnetic member 2, a part of the medium component 4 can always be located inside the magnetic member 2 (i.e., a part of the medium component 4 is located in the magnetic member 2 for magnetic separation), while the other part is located in the cleaning area for cleaning, so that the medium component 4 can always be in the working state of magnetic separation and cleaning, so as to improve the magnetic separation efficiency of the slurry. At least two flushing areas can facilitate further improving the magnetic separation efficiency.

[0049] First, the first linear drive device 11 moves the second flow regulating plate 62 until it is in a closed state with the first flow regulating plate 61, and then the slurry to be magnetically separated is input into the slurry tank 3 through the slurry inlet pipe 12 until the medium component 4 is completely immersed in the slurry. At this time, the medium component 4 completes the magnetic separation under the action of the magnetic field of the magnetic member 2; then, the second linear drive device 16 drives the first part of the medium component 4 to move to the nearest flushing area 5, and then, under the action of the nozzle 14, a large amount of minerals and water attached to the medium component 4 fall into the collecting plate 51, and at the same time, the second part of the medium component 4 also enters the slurry tank 3 for magnetic separation; similarly, the second linear drive device 16 drives the second part of the medium component 4 to move to another flushing area 5 and perform the flushing process, and at the same time, the first part of the medium component 4 also enters the slurry tank 3 again for magnetic separation, and the above actions are repeated in this way, so that the device can maintain the magnetic separation action; during the magnetic separation process, the user can adjust the flow rate of the slurry by adjusting the flow regulating component 6 according to actual needs, so as to improve the magnetic separation efficiency of the equipment.

[0050] Embodiment 2:

[0051] The difference between this embodiment and the first embodiment is that a flow regulating component 6 is connected to the slurry tank 3 and is used to control the outflow of slurry and keep the medium component 4 immersed in the slurry. By controlling the flow regulating component 6 so that the slurry in the slurry tank 3 flows in and out naturally, the medium component 4 can be kept immersed in the slurry, thereby facilitating the improvement of the efficiency of magnetic separation.
