Description

Technical Field

[0001] This utility model relates to the field of magnetic separation device technology, and in particular to a dry magnetic separation device. Background Technology

[0002] In the field of mineral processing and beneficiation, dry magnetic separators are commonly used to separate and enrich minerals with different magnetic properties, thereby improving ore grade or recovering valuable mineral components. In the field of material separation and purification, dry magnetic separators are also used to remove magnetic impurities from raw materials, improving product quality and performance.

[0003] Currently, existing dry magnetic separators can separate larger particles, but they are less effective at separating fine magnetic and non-magnetic particles. Utility Model Content

[0004] The purpose of this invention is to provide a dry magnetic separator that can improve the separation effect of fine magnetic particles and non-magnetic particles.

[0005] To achieve the above objectives, this utility model provides a dry magnetic separator, comprising:

[0006] A support frame is provided with a first conveying roller and a second conveying roller arranged sequentially along a first direction. Both the first and second conveying rollers extend along a second direction. A conveyor belt is connected to the first and second conveying rollers. The upper tangent points of the first and second conveying rollers rotate toward the first direction. The first conveying roller is a magnetic roller.

[0007] An air blowing assembly, wherein the air blowing port of the air blowing assembly faces the side of the first conveying roller away from the second conveying roller and is on a plane parallel to a third direction, and the orthographic projection of the air blowing port is within the orthographic projection of the first conveying roller;

[0008] A collection component, which is mounted on the bracket, has an upward-facing first opening located below the air inlet and the first conveying roller;

[0009] The discharge component is mounted on the bracket and has an upward-facing second opening located below the second conveying roller.

[0010] The first direction, the second direction, and the third direction are perpendicular to each other.

[0011] Preferably, the air blowing assembly includes:

[0012] Gas generator;

[0013] A powder feeder, wherein the powder feeder is provided with the air blowing port;

[0014] A gas supply pipe, the two ends of which are respectively connected to the gas generator and the powder feeder;

[0015] The material feeder is connected to the air supply pipe at its bottom.

[0016] Preferably, the powder feeder extends outward from both ends in the second direction along the first direction.

[0017] Preferably, the feeder is funnel-shaped.

[0018] Preferably, the two side walls of the discharge member in the first direction gradually extend inward along the third direction, the discharge member has a discharge port on the side wall in the second direction, and the bottom wall of the discharge member gradually extends downward along the second direction to the discharge port.

[0019] Preferably, the shape of the collecting element is an inverted cone.

[0020] Preferably, it further includes:

[0021] A drive assembly connected to the second conveying roller, the drive assembly being used to drive the second conveying roller to rotate.

[0022] Preferably, the drive assembly includes a motor and a belt, the output shaft of the motor extending in a second direction, and the belt wound around the output shaft of the motor and the roller shaft of the second conveying roller.

[0023] Preferably, the motor is mounted on the bracket.

[0024] Preferably, the support includes:

[0025] A first frame extends along the first direction and the second direction, a first conveying roller and a second conveying roller are mounted on the top of the first frame, and the collecting element and the discharging element are mounted on the bottom of the first frame.

[0026] A second frame is parallel to the first frame and is connected below the first frame. The motor is mounted on the second frame.

[0027] Preferably, the collecting component is installed on the first frame, and the discharging component is installed on the first frame.

[0028] Compared with the prior art, the dry magnetic separation device of this utility model has the following advantages:

[0029] The material is blown out through the air outlet of the air blowing assembly. Since the air outlet faces the side of the first conveyor roller away from the second conveyor roller and is on a plane parallel to the third direction, the orthographic projection of the air outlet is within the orthographic projection of the first conveyor roller. Therefore, the blown material can contact the conveyor belt on the side of the first conveyor roller away from the second conveyor roller in the first direction.

[0030] Because the first conveyor roller is a magnetic roller, magnetic particles are attracted to the conveyor belt there due to magnetic attraction. Since the upper tangent points of the first and second conveyor rollers rotate in the first direction, the conveyor belt connecting the tops of the first and second conveyor rollers moves along the first direction, and the magnetic particles gradually reach the second conveyor roller along with it. Due to gravity, the magnetic particles fall into the second opening of the discharge component below the second conveyor roller. Non-magnetic particles, after impacting the conveyor belt at the first conveyor roller, do not experience magnetic attraction and therefore fall into the air inlet and the first opening of the collection component below the first conveyor roller due to gravity.

[0031] In this application, under the action of a gaseous medium, magnetic agglomerates of different particle sizes and densities disperse due to different forces. Combining the structural relationship of the air nozzle, magnetic roller and conveyor belt, magnetic particles and non-magnetic particles are separated, and the separation effect of fine magnetic particles and non-magnetic particles is better.

[0038] like Figure 1-2 As shown, a dry magnetic separator according to an embodiment of the present invention includes: a support 1, an air blowing assembly 5, a collecting component 6, and a discharging component 7;

[0039] A first conveyor roller 2 and a second conveyor roller 3 are sequentially arranged on the support 1 along the first direction X. Both the first conveyor roller 2 and the second conveyor roller 3 extend along the second direction Y. A conveyor belt 4 is connected to the first conveyor roller 2 and the second conveyor roller 3. The upper tangent point of the first conveyor roller 2 and the second conveyor roller 3 rotates toward the first direction X. The first conveyor roller 2 is a magnetic roller.

[0040] The air blowing port 51 of the air blowing assembly 5 faces the side of the first conveying roller 2 away from the second conveying roller 3, and on a plane parallel to the third direction Z, the orthographic projection of the air blowing port 51 is within the orthographic projection of the first conveying roller 2.

[0041] The collecting component 6 is mounted on the bracket 1. The collecting component 6 has an upward first opening 61, which is located below the air blowing port 51 and the first conveying roller 2.

[0042] The discharge component 7 is installed on the bracket 1. The discharge component 7 has an upward second opening 71, which is located below the second conveying roller 3.

[0043] Among them, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0044] It should be noted that when the material is blown out through the air outlet 51 of the air blowing assembly 5, since the air outlet 51 faces the side of the first conveyor roller 2 away from the second conveyor roller 3 and is on a plane parallel to the third direction Z, the orthographic projection of the air outlet 51 is within the orthographic projection of the first conveyor roller 2. Therefore, the blown material can contact the conveyor belt 4 on the side of the first conveyor roller 2 away from the second conveyor roller 3 in the first direction X.

[0045] Since the first conveyor roller 2 is a magnetic roller, the magnetic particles will be attracted to the conveyor belt 4 at that location due to magnetic attraction. As the upper tangent points of the first conveyor roller 2 and the second conveyor roller 3 rotate in the first direction X, the conveyor belt 4 connecting the tops of the first conveyor roller 2 and the second conveyor roller 3 moves along the first direction X. The magnetic particles also gradually reach the second conveyor roller 3 along with the conveyor belt 4. Due to gravity, the magnetic particles fall into the second opening 71 of the discharge part 7 below the second conveyor roller 3. Non-magnetic particles, after hitting the conveyor belt 4 at the first conveyor roller 2, fall into the air inlet 51 and the first opening 61 of the collection part 6 below the first conveyor roller 2 due to the lack of magnetic attraction.

[0046] In this application, under the action of a gaseous medium, magnetic agglomerates of different particle sizes and densities disperse due to different forces. Combined with the structural relationship of the air nozzle, magnetic roller and conveyor belt 4, magnetic particles and non-magnetic particles are separated, and the separation effect of fine magnetic particles and non-magnetic particles is better.

[0047] In this embodiment, the blowing assembly 5 further includes: a gas generator 52, a powder feeder 53, an air supply pipe 54, and a feeding component 55;

[0048] The powder feeder 53 is equipped with an air inlet 51, and the two ends of the air supply pipe 54 are respectively connected to the gas generator 52 and the powder feeder 53. The bottom of the material feeder 55 is connected to the air supply pipe 54.

[0049] It should be noted that when the material is placed into the feeding part 55, the gas generator 52 transmits gas to the gas supply pipe 54, and the gas blows the material from the gas supply pipe 54 to the powder feeder 53, and the powder feeder 53 blows the material out.

[0050] In this embodiment, the powder feeder 53 further extends outward from both ends in the second direction Y along the first direction X.

[0051] It should be noted that the two ends of the powder feeder 53 in the second direction Y gradually extend outward along the first direction X, so as to blow the material in the air supply pipe 54 out of the powder feeder 53 more evenly.

[0052] In this embodiment, the feeder 55 is further shaped as a funnel.

[0053] It should be noted that the feeding component 55 is funnel-shaped, with a larger opening at the top for easy material placement and a smaller opening at the bottom to collect and transport the material into the air supply pipe 54.

[0054] In this embodiment, the two side walls of the discharge member 7 in the first direction X gradually extend inward along the third direction Z, the discharge member 7 has a discharge port 72 on the side wall in the second direction Y, and the bottom wall of the discharge member 7 gradually extends downward along the second direction Y to the discharge port 72.

[0055] It should be noted that the two side walls of the discharge component 7 in the first direction X gradually extend inward along the third direction Z, so that the magnetic particles falling onto the discharge component 7 can gather on the bottom wall of the discharge component 7. The bottom wall of the discharge component 7 gradually extends downward along the second direction Y to the discharge port 72, so that the magnetic particles can be discharged from the discharge port 72 along the inclined bottom wall.

[0056] In this embodiment, the collecting element 6 is further shaped as an inverted cone.

[0057] It should be noted that the shape of the collector 6 is an inverted cone, so that non-magnetic particles entering from the first opening 61 can slide down the inner wall of the collector 6 and accumulate at the bottom of the collector 6.

[0058] In this embodiment, it further includes a drive component 8, which is connected to the second conveying roller 3 and is used to drive the second conveying roller 3 to rotate.

[0059] It should be noted that by driving the second conveyor roller 3 to rotate through the drive component 8, thereby driving the first conveyor roller 2 to rotate and the conveyor belt 4 to move, the first conveyor roller 2, the second conveyor roller 3 and the conveyor belt 4 can be started synchronously, making the conveying structure simpler.

[0060] In this embodiment, the drive assembly 8 further includes a motor 81 and a belt 82. The output shaft of the motor 81 extends along the second direction Y, and the belt 82 is wound around the output shaft of the motor 81 and the roller shaft of the second conveying roller 3.

[0061] It should be noted that the motor 81 drives the output shaft to rotate, thereby driving the belt 82 to move, which in turn drives the roller shaft of the second conveyor roller 3 to rotate. The power transmission of the output shaft can be gently transmitted to the second conveyor roller 3 through the belt 82, effectively buffering the impact load.

[0062] In this embodiment, the motor 81 is further mounted on the bracket 1.

[0063] It should be noted that the motor 81 is mounted on the bracket 1, so when the bracket 1 moves, the motor 81 can move along with it.

[0064] In this embodiment, the support 1 further includes: a first frame 11 and a second frame 12; the first frame 11 extends along a first direction X and a second direction Y, a first conveying roller 2 and a second conveying roller 3 are installed on the top of the first frame 11, and a collecting component 6 and a discharging component 7 are installed on the bottom of the first frame 11; the second frame 12 is parallel to the first frame 11 and is connected below the first frame 11, and a motor 81 is installed on the second frame 12.

[0065] It should be noted that the first conveying roller 2 and the second conveying roller 3 are installed on the top of the first frame 11, and the collecting component 6 and the discharging component 7 are installed at the bottom of the first frame 11, so that the particles passing through the first conveying roller 2 and the second conveying roller 3 can fall into the collecting component 6 or the discharging component 7 as soon as possible.

[0066] The motor 81 is mounted on the second frame 12 below the first frame 11, which saves space.

[0067] The first frame 11 is a rectangular frame formed by connecting four support rods end to end, and the second frame 12 is a rectangular frame formed by connecting four support rods end to end.

[0068] The working process of this utility model is as follows: the material is blown out through the air outlet 51 of the air blowing assembly 5. Since the air outlet 51 faces the side of the first conveying roller 2 away from the second conveying roller 3 and is on a plane parallel to the third direction Z, the orthographic projection of the air outlet 51 is within the orthographic projection of the first conveying roller 2. Therefore, the blown material can contact the conveyor belt 4 of the first conveying roller 2 on the side away from the second conveying roller 3 in the first direction X.

[0069] Since the first conveyor roller 2 is a magnetic roller, the magnetic particles will be attracted to the conveyor belt 4 at that location due to magnetic attraction. As the upper tangent points of the first conveyor roller 2 and the second conveyor roller 3 rotate in the first direction X, the conveyor belt 4 connecting the tops of the first conveyor roller 2 and the second conveyor roller 3 moves along the first direction X. The magnetic particles also gradually reach the second conveyor roller 3 along with the conveyor belt 4. Due to gravity, the magnetic particles fall into the second opening 71 of the discharge part 7 below the second conveyor roller 3. Non-magnetic particles, after hitting the conveyor belt 4 at the first conveyor roller 2, fall into the air inlet 51 and the first opening 61 of the collection part 6 below the first conveyor roller 2 due to the lack of magnetic attraction.

[0070] In summary, this utility model provides a dry magnetic separator that can improve the separation effect of fine magnetic particles and non-magnetic particles.

[0071] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
