Description

[0001] The invention relates to the technical field of ore dressing devices, and in particular to a combined medium box. Background Art

[0002] The medium box is a key component of the vertical ring high gradient magnetic separator. It plays an important role in sorting and transporting magnetic minerals in the production process. During operation, when the medium box runs to the magnetic field feeding area, the slurry passes through the ore seam of the medium box. At this time, the magnetic medium of the medium box senses the magnetic field, adsorbs the magnetic minerals in the slurry, and the non-magnetic minerals flow out through the ore seam. As the rotating ring rotates, the medium box that adsorbs the magnetic minerals passes through the magnetic field area and enters the unloading area. The magnetic medium is demagnetized, and the unloading water washes away the magnetic minerals on the medium box, and the cycle repeats. From the working state of the medium box, it can be seen that this component must not only have a good slurry passing capacity, but also have the characteristics of not being easy to block and easy to clean; at the same time, the medium box circulates in the magnetic field area and the non-magnetic field area, and is repeatedly stretched by magnetic force, and must also have sufficient tensile strength.

[0030] See also Figures 1 to 7 , shown is a combined media box in an embodiment of the present invention, including a box body 10, a media stack assembly 20 for magnetic separation arranged in the box body 10, and a pressure rod 30 arranged at the top of the box body 10, the box body 10 includes a frame 11 composed of four flat plates and a support member 12 arranged at the bottom of the frame 11, the support member 12 is composed of a plurality of staggered support rods so that the support member 12 has a hollow structure, and both ends of the support rod are connected to the frame 11, the media stack assembly 20 includes a plurality of stacked media stacks 21, the media stack 21 includes a support plate 211 and a magnetic steel wire 212 arranged on the support plate 211, and an installation groove 13 adapted to the pressure rod 30 is provided on the top of the box body 10, so that the pressure rod 30 is embedded in the installation groove 13 to fix the media stack assembly 20 in the box body 10.

[0031] It can be understood that by setting the box body 10 and setting the medium stack assembly 20 in the box body 10, when magnetic separation is performed, the mineral water passes through the medium stack assembly 20 and flows out from the hollow support member at the bottom of the box body 10, and the magnetic separation effect is achieved through the medium stack 21 to adsorb the magnetic minerals on the medium stack 21. Specifically, by setting the pressure rod 30 to cooperate with the mounting groove 13 on the box body 10, the medium stack assembly 20 is fixed in the box body 10, and then magnetic separation is performed through the medium stack assembly 20. Since the pressure rod 30 is detachably connected to the box body 10, the medium stack assembly 20 can be taken out of the box body 10 for cleaning after magnetic separation, which greatly reduces the difficulty of cleaning. In addition, the detachable connection method makes it possible to clean the box body. The medium stack 21 in the box body 10 is replaced, the medium stack 21 after magnetic separation is cleaned to obtain magnetic materials, and the medium stack 21 for magnetic separation is placed in the box body 10 for magnetic separation, which greatly improves the work efficiency. Due to the detachable modular design, it is not necessary to replace the entire medium box when it is partially damaged, which avoids material waste and reduces the cost of parts replacement. In addition, the medium stack assembly 20 is composed of multiple medium stacks 21 stacked together, so that when performing magnetic separation, different single medium stacks 21 can be made of different materials according to needs, and then a composite medium stack 21 composed of a combination of multiple magnetic conductive materials can be configured to meet the needs of different minerals for media, greatly improving the versatility and application prospects of the medium box. Therefore, the present invention solves the problem that the medium box in the prior art is difficult to maintain and difficult to clean after being blocked.

[0032] Specifically, the medium stack 21 includes a plurality of support plates 211 arranged in parallel, and a connection hole adapted to the magnetic steel wire 212 is provided on the support plate 211, and the connection hole is arranged in parallel on the support plate 211, and a plurality of magnetic steels are connected to the outer support plate 211 at both ends by passing through the connection hole, so as to form a parallel magnetic network between the plurality of support plates 211. In the specific implementation, at least two support plates 211 arranged in parallel are included, and a plurality of magnetic steel wires 212 are arranged in parallel between the two support plates 211 by opening a connection hole on the support plate 211. More specifically, the magnetic steel wire 212 is arranged perpendicular to the support plate 211, so that a plurality of layers of magnetic network are distributed between the two support plates 211 to improve the magnetic separation efficiency of the mineral water. In addition, a plurality of support plates 211 can be arranged, and by setting a plurality of support plates 211, it is avoided that when a large medium stack 21 is set, the magnetic steel wire 212 constituting the magnetic network is too long, and the force is too large to exceed the material limit, thereby affecting the service life of the magnetic steel wire 212.

[0033] In addition, the medium stack 21 includes a plurality of support plates 211 connected end to end to form a rectangular enclosure, and a plurality of fixing holes 213 are provided on the support plate 211. The plurality of fixing holes 213 are oriented in the same direction and form a certain angle with the long side of the enclosure. The two ends of the plurality of magnetic conductive steel wires 212 are connected to the enclosure through the fixing holes 213 to form a parallel and obliquely arranged magnetic conductive network in the enclosure. In addition, in addition to setting the vertically distributed magnetic conductive steel wires 212, obliquely distributed magnetic conductive steel wires 212 can also be set. Relative to the vertically distributed magnetic conductive steel wires 212, the obliquely arranged magnetic conductive steel wires 212 are more suitable for the medium stack 21 with a smaller size. The obliquely arranged magnetic conductive steel wires 212 can achieve more magnetic field density, i.e., magnetic field effect, by setting a smaller number of magnetic conductive steel wires 212. Relative to the vertically arranged magnetic conductive steel wires 212, the number of magnetic conductive steel wires 212 used is less, and the cost is lower. In addition, the small number reduces the production difficulty of the medium stack 21.

[0034] Specifically, the medium stack assembly 20 includes a plurality of medium stacks 21, and the magnetic conductive nets of adjacent medium stacks 21 have different inclination angles. In a specific implementation, the medium stack assembly 20 can be provided with a plurality of medium stacks 21 of different materials to improve the application range of the medium box. In addition, by tilting the magnetic conductive wire 212, and then setting the inclination angles of the magnetic conductive wire 212 of adjacent medium stacks 21 to be different, under the same space and magnetic field environment, the path of part of the mineral water flowing in the medium box is longer, that is, the residence time is longer, so as to enhance the magnetic separation effect of the medium stack 21, and then enhance the overall effect of the magnetic separation of the medium box, without the need to add more magnetic conductive wires 212 or the number or volume of the medium stack assembly 20. The medium stack 21 includes a plurality of magnetic conductive wires 212 to form a magnetic conductive net, and a plurality of magnetic conductive nets are stacked and fixed in the box body 10. In a specific implementation, a finished magnetic conductive net can also be used, by cutting the magnetic conductive net into a desired shape.

[0035] In addition, the pressure rod 30 includes a first pressure rod portion 31 and a second pressure rod portion 32. The first pressure rod portion 31 has a screw portion 33 extending outward from one side close to the second pressure rod portion 32. The second pressure rod portion 32 is provided with a screw hole 34 adapted to the screw portion 33, so that the length of the pressure rod 30 can be adjusted. By setting the pressure rod 30 into the first pressure rod portion 31 and the second pressure rod portion 32, and by the screw portion 33 and the screw hole 34, the first pressure rod portion 31 and the second pressure rod portion 32 can be close to or away from each other, so that the pressure rod 30 can be embedded in the installation groove 13 to fix the medium stack assembly 20, so that the medium stack assembly 20 is stably located in the box body 10, and the magnetic separation function is smoothly realized.

[0036] Specifically, a cylindrical portion 35 adapted to the mounting groove 13 is extended outward from opposite sides of the first pressing rod portion 31 and the second pressing rod portion 32, and the diameter of the cylindrical portion 35 is smaller than the diameter of the pressing rod 30. In a specific implementation, the cylindrical portions 35 provided on both sides of the pressing rod 30 are adapted to the mounting groove 13, so that the pressing rod 30 is embedded in the mounting groove 13 to limit the medium stack 21.

[0037] By way of example but not limitation, in some optional embodiments, a triangular limiting portion 36 and a cylindrical positioning portion 37 are respectively extended outwardly from opposite sides of the first pressing rod portion 31 and the second pressing rod portion 32, a mounting groove 13 adapted to the limiting portion 36 and the positioning portion 37 is provided on the box body 10, and a protrusion 38 is provided on the outer side of the second pressing rod portion 32. In specific implementation, in order to ensure that the medium stack assembly 20 composed of multiple medium stacks 21 can be accommodated, the box body 10 is usually set larger, that is, it can accommodate two or more medium stacks 21, and due to the use requirements and the detachable property of the medium stack assembly 20, it may be faced with a situation where fewer medium stacks 21 are required, that is, only two or one medium stack 21 is required, and in order to ensure the stable operation of the medium stack 21, the pressing rod 30 is still required to press the medium stack 21, so the mounting groove 13 is also provided on the inner side of the box body 10 to cooperate with the pressing rod 30 to adapt to the situation of different numbers of medium stacks 21. In addition, in order to ensure the magnetic separation effect of mineral water, the installation groove 13 cannot penetrate the box body 10 to prevent the mineral water from flowing out of the box body 10 from the installation groove 13, affecting the magnetic separation efficiency of the medium box. In addition, compared with the pressure rod 30 set at the top of the box body 10, the mineral water or slurry can be made to flow into the medium pile 21 from between the pressure rods 30 by adjusting the water inlet direction. When the number of medium piles 21 is small, the pressure rod 30 set in the box body 10 is inevitably affected by the impact of the mineral water or slurry. The pressure rod 30 is limited by the rotation of the first pressure rod part 31 and the second pressure rod part 32. Therefore, under the impact, the first pressure rod part 31 and the second pressure rod part 32 may rotate relative to each other, so that the length of the pressure rod 30 is shortened and separated from the installation groove 13. Therefore, by respectively providing a three-shaped limiting portion 36 and a cylindrical positioning portion 37, when in use, the limiting portion 36 is first inserted into the mounting groove 13 on one side, and the second pressure rod portion 32 is rotated by the protrusion 38 to make the pressure rod 30 longer, thereby making the positioning portion 37 embedded in the mounting groove 13. Since the protrusion 38 is provided, the length of the pressure rod 30 or the pitch of the screw portion 33 can be reasonably set so that after the pressure rod 30 is assembled, the protrusion 38 is located at a specific side or bottom, and then when the mineral water or slurry impacts, the action on the protrusion 38 will only make the pressure rod 30 extend longer, or under the impact of the pressure rod 30, the protrusion 38 rotates in the opposite direction from the bottom to the side, and then because the protrusion 38 is easier to withstand force than the main body of the pressure rod 30, it returns to the bottom under the impact, thereby avoiding the situation where the pressure rod 30 is separated from the mounting groove 13. In addition, by reasonably setting the pitch of the screw portion 33, the displacement of the second pressure rod portion 32 relative to the first pressure rod portion 31 after one rotation can be smaller, and there is no need to limit the position of the protrusion 38. Under the action of impact, the protrusion 38 will only rotate by an angle less than one circle, and it is impossible for the pressure rod 30 to disengage from the mounting groove 13.

[0038] Specifically, a positioning block 214 is extended outward from the top of the support plate 211, and the bottom of the support portion is recessed inward to form a positioning groove 215 adapted to the positioning block 214. In addition, by providing the positioning block 214 and the positioning groove 215 to cooperate, the vector dielectric stack 21 can be quickly assembled and positioned to form the dielectric stack assembly 20 under the cooperation of the two, thereby ensuring the stability and uniformity of the magnetic field distribution.

[0039] In addition, the positioning block 214 is located on the support plate 211 at the width position of the enclosure, and the positioning block 214 is also provided with a mounting groove 13. By providing the mounting groove 13 on the positioning block 214, specifically, when the medium stack 21 needs to be cleaned and disassembled, the pressure rod 30 can be assembled on the medium stack 21 through the cooperation between the pressure rod 30 and the mounting groove 13, and then the medium stack 21 can be lifted by grabbing the pressure rod 30, which greatly reduces the difficulty of disassembling the medium stack 21.

[0040] Specifically, an ear plate 40 is provided on the outer side of the top of the box body 10, and a semicircular hole 41 is provided on the outer side of the ear plate 40. Specifically, by providing a large ear plate 40 on the outer side of the box body 10 and providing a semicircular hole 41 on the ear plate 40, the box body 10 is fixed at a preset position by fixing bolts and the semicircular hole 41, and the large ear plate 40 made of steel bars has a larger force-bearing surface, thereby improving the strength of the medium box ear plate 40 and reducing the risk of tearing of the frame 11 box side plate.

[0041] In summary, a combined media box in the above-mentioned embodiment of the present invention, by setting a box body 10 and setting the media stack assembly 20 in the box body 10, allows the mineral water to pass through the media stack assembly 20 and flow out from the hollow support at the bottom of the box body 10 during magnetic separation, and achieves the effect of magnetic separation through the media stack 21 to adsorb the magnetic minerals on the media stack 21. Specifically, by setting a pressure rod 30 to cooperate with the mounting groove 13 on the box body 10, the media stack assembly 20 is fixed in the box body 10, and then magnetic separation is performed through the media stack assembly 20. Since the pressure rod 30 is detachably connected to the box body 10, the media stack assembly 20 can be taken out of the box body 10 for cleaning after magnetic separation, which greatly reduces the difficulty of cleaning. In addition, the detachably connected The method makes it possible to replace the medium stack 21 in the box body 10, clean the medium stack 21 after magnetic separation to obtain magnetic materials, and place the medium stack 21 for magnetic separation in the box body 10 for magnetic separation, which greatly improves the work efficiency. Due to the detachable modular design, it is not necessary to replace the entire medium box in the event of local damage, thus avoiding material waste and reducing the cost of parts replacement. In addition, the medium stack assembly 20 is composed of a plurality of medium stacks 21 stacked together, so that when performing magnetic separation, different single medium stacks 21 can be made of different materials according to needs, and then a composite medium stack 21 composed of a combination of multiple magnetic conductive materials can be configured, thereby meeting the needs of different minerals for the medium, greatly improving the versatility and application prospects of the medium box. Therefore, the present invention solves the problem that the medium box in the prior art is difficult to maintain and difficult to clean after being blocked.

[0042] In addition, the present invention also provides a method for preparing a medium box, which is used to prepare the above-mentioned combined medium box. Specifically, the frame 11 box: steel plates are selected and welded into a rectangular frame 11 box, a cross-shaped grid is welded at the bottom of the frame 11 box, and concentric holes are drilled on the steel plates on the top short sides for installing the pressure rod 30; a large ear plate 40 is set on the top of the frame 11 box, and is fully welded on both sides of the top long side. Single medium stack 21: steel plates are selected and drilled, and magnetic steel rods are passed through and then fully welded, and polished to a preset size. The combined medium box can use multiple single medium stacks 21 to form a combined medium stack 21. Pressure rod 30: steel rods are selected, cut to the required size, and holes are drilled or polished on both sides. When in use, the single medium stack 21 is placed in the frame 11 box to form a combined medium stack 21, and the medium stack 21 is fixed with a pressure rod 30 to form a combined medium box.
