Description

Technical Field

[0001] The utility model relates to the technical field of ore dressing devices, in particular to an iron ore magnetic separation device. Background Art

[0002] Iron ore magnetic separation is a method of mineral separation that uses the magnetic difference between iron ore and gangue to improve the grade of iron ore for subsequent processing and application. The principle is that magnetic minerals in iron ore (such as magnetite) will be magnetized under the action of the magnetic field and attracted to the magnetic poles of the magnetic separator, while non-magnetic or weakly magnetic minerals (such as quartz, feldspar, etc.) will not be magnetized, thereby achieving separation.

[0003] The utility model patent with authorization announcement number CN 221245604 U discloses an iron ore magnetic separation device. This solution rotates the rotating plate to drive the electromagnets at both ends to rotate above the conveyor belt and the feed belt. After magnetic separation, the iron ore magnetically attracted from the conveyor belt can be conveniently transported to the feed belt through rotation. The two electromagnets operate alternately to achieve non-stop ore separation.

[0004] However, one end of the rotating plate has magnetically attracted the ore and there is a gap during the rotation adjustment process where ore dressing cannot continue, but the conveyor belt is still conveying ore at this time. Therefore, some ore will continue to be conveyed in the gap where ore dressing cannot be carried out, resulting in omissions. Simply increasing the number of such devices will increase the cost, making it difficult to meet usage needs. Utility Model Content

[0005] The purpose of this utility model is to provide an iron ore magnetic separation device to address the above-mentioned shortcomings and to achieve continuous magnetic separation of iron ore without stopping the machine.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: an iron ore magnetic separation device, comprising:

[0007] A magnetic separation cylinder and a power device, wherein the magnetic separation cylinder includes a cylindrical magnetic separation section, which is composed of a plurality of arc-shaped electromagnetic plates and connecting plates connected to each other, and the power device is used to drive the magnetic separation cylinder to rotate;

[0008] a power supply assembly for supplying power to the remaining electromagnetic plates other than those rotating to the upper side of the magnetic separation cylinder, so that the corresponding electromagnetic plates magnetically attract the iron ore in the magnetic separation cylinder and cause the iron ore on the electromagnetic plates rotating to the upper side of the magnetic separation cylinder to fall;

[0009] The spiral blade is arranged on the inner wall of the magnetic separation cylinder. When the magnetic separation cylinder rotates, the spiral blade is driven to rotate, so as to transport the residual material to the output end;

[0010] The transport device is used to transport the falling iron ore and the remaining material output from the magnetic separation cylinder separately.

[0011] Furthermore, the magnetic separation cylinder also includes mounting sections arranged on both sides of the magnetic separation section and having a cylindrical shape. A support is rotatably provided on each of the mounting sections. The power equipment is arranged on the corresponding support. The power equipment includes a ring gear arranged on the corresponding mounting section, a motor arranged on the support, and a gear arranged at the moving end of the motor. The gear is engaged with the ring gear. When the motor is working, the gear rotates to drive the ring gear and the magnetic separation cylinder to rotate synchronously.

[0012] Furthermore, the mounting section is rotatably provided with a rolling wheel in contact with the support.

[0013] Furthermore, the magnetic selection section also includes a power-on ring arranged on the magnetic selection section, the power-on ring is annular, and is provided with a plurality of power-on ends distributed in a ring and corresponding one to one with each of the electromagnetic plates. The power supply component includes a conductive ring in a ring shape with a missing top, and the power-on ring is located inside the conductive ring, so that the corresponding power-on ends are electrically connected to the conductive ring.

[0014] Furthermore, the transportation device includes a first conveying platform and a second conveying platform. The first conveying platform is located inside the magnetic separation cylinder, and is used to carry the iron ore that falls after magnetic attraction and transport it to its output end. The width of the electromagnetic plate is smaller than the width of the first conveying platform. The second conveying platform is located inside and outside the magnetic separation cylinder, and is used to carry the residual material output by the magnetic separation cylinder and transport it to its output end. The second conveying platform is provided with a bracket extending outside the magnetic separation cylinder.

[0015] Furthermore, the second conveyor platform is provided with a driving device for driving it to move, and a transmission belt group is provided at the moving ends of the first conveyor platform and the second conveyor platform. The transmission belt group includes two transmission wheels and a transmission belt provided on the two transmission wheels and transmitting to each other, wherein one of the transmission wheels is provided at the moving end of the first conveyor platform, and the other transmission wheel is provided at the moving end of the second conveyor platform.

[0016] The beneficial effects of the present invention are as follows:

[0017] The utility model controls the rotation of the magnetic separation cylinder through a power device, and the spiral blades also rotate synchronously, thereby driving the ore located inside the magnetic separation cylinder to be transported toward the output end of the magnetic separation cylinder. During this process, the power supply component cooperates with the external power supply to power the corresponding electromagnetic plate, so that the iron ore that can be magnetically attracted is adsorbed on the corresponding electromagnetic plate. As the magnetic separation cylinder continues to rotate, the remaining material in the ore that cannot be magnetically attracted will be directly transmitted out. During this process, the electromagnetic plate rotated to the upper side of the magnetic separation cylinder will change from the original power-on state to the power-off state, and it will lose its magnetic attraction ability, so that the iron ore originally magnetically attracted by the electromagnetic plate will fall down and fall onto the transportation device. The transportation device will separately transport the iron ore and the remaining material output by the magnetic separation cylinder. This method can perform uninterrupted magnetic attraction, which is convenient for practical use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-4The utility model discloses an iron ore magnetic separation device, including a magnetic separation cylinder, a power device 8 and a power supply assembly. The magnetic separation cylinder includes a magnetic separation section 2 with a cylindrical appearance. The magnetic separation section 2 is composed of a plurality of arc-shaped electromagnetic plates 21 and connecting plates 22 connected to each other. The power device 8 is used to drive the magnetic separation cylinder to rotate. When in use, unmagnetically separated ore is put into the magnetic separation cylinder from the input end.

[0026] In one embodiment, the power supply assembly is used to power the remaining electromagnetic plates 21 other than those rotated to the upper side of the magnetic separation cylinder, so that the corresponding electromagnetic plates 21 magnetically attract the iron ore in the magnetic separation cylinder and cause the iron ore on the electromagnetic plates 21 rotated to the upper side of the magnetic separation cylinder to fall. A spiral blade 5 is installed on the inner wall of the magnetic separation cylinder. When the magnetic separation cylinder rotates, the spiral blade 5 is driven to rotate to transport the residual material to the output end. The device also includes a transport device 6, which is used to separately transport the falling iron ore and the residual material output by the magnetic separation cylinder.

[0027] In the specific implementation, the rotation of the magnetic separation cylinder is controlled by the power equipment 8, and the spiral blade 5 will also rotate synchronously, thereby driving the ore located inside the magnetic separation cylinder to be transported toward the output end of the magnetic separation cylinder. During this process, the power supply component cooperates with the external power supply to power the corresponding electromagnetic plate 21, so that the iron ore that can be magnetically attracted is adsorbed on the corresponding electromagnetic plate 21. As the magnetic separation cylinder continues to rotate, the residual material in the ore that cannot be magnetically attracted will be directly transmitted out. During this process, the electromagnetic plate 21 rotated to the upper side of the magnetic separation cylinder will change from the original power-on state to the power-off state, and it loses its magnetic attraction ability, so that the iron ore originally magnetically attracted by the electromagnetic plate 21 will fall down and fall on the transportation device 6. The transportation device 6 will transport the iron ore and the residual material output by the magnetic separation cylinder separately. This method can perform uninterrupted magnetic mineral separation, which is convenient for practical use.

[0028] It should be noted that when pouring unmagnetized ore into the magnetic separation cylinder, the amount poured cannot exceed the width of the spiral blade 5. This design is to prevent excessive ore from being poured in and affecting its normal transportation and magnetic separation capabilities.

[0029] In one embodiment, the magnetic separation cylinder also includes mounting sections 1 installed on both sides of the magnetic separation section 2 and having a cylindrical shape. A support 3 is rotatably installed on each mounting section 1, and a power device 8 is arranged on the corresponding support 3. The power device 8 includes a ring gear (not shown in the figure) installed on the corresponding mounting section 1, a motor installed on the support 3, and a gear (not shown in the figure) arranged at the moving end of the motor, and the gear is meshed with the ring gear.

[0030] In a specific implementation, the support 3 is placed on a mounting surface (such as the ground), and is used to support the magnetic separation cylinder without affecting its rotation. When the motor is working, it drives the gear to rotate, and the gear is used to drive the ring gear and the magnetic separation cylinder to rotate synchronously.

[0031] In one embodiment, a rolling wheel that is rotatably provided on the mounting section 1 and contacts the support 3 .

[0032] With this design, when the mounting section 1 rotates, the rolling wheel is in continuous contact with the support 3, so that the entire magnetic separation cylinder rotates more stably and smoothly.

[0033] In one embodiment, the magnetic selection section 2 also includes a power ring 23 installed on the magnetic selection section 2. The power ring 23 is annular and has multiple power ends 24 distributed in an annular shape and corresponding one to one with each electromagnetic plate 21. The power supply component includes a conductive ring 4 in an annular shape with a missing top. The power ring 23 is located inside the conductive ring 4, so that the corresponding power ends 24 are electrically connected to the conductive ring 4.

[0034] In a specific implementation, the conductive ring 4 is connected to an external power supply, thereby connecting the corresponding powered end 24 on the powered ring 23 located therein and the corresponding electromagnetic plate 21 to power on. After the above-mentioned electromagnetic plate 21 is powered on, it will have magnetic force, thereby being able to magnetically attract iron ore. However, there is a missing portion on the top of the conductive ring 4, which corresponds to one of the electromagnetic plates 21. Therefore, during the continuous rotation of the magnetic separation section 2, there will always be an electromagnetic plate 21 that is not powered, thereby changing from having magnetic attraction ability to having no magnetic attraction ability. Therefore, the iron ore originally magnetically attracted by the electromagnetic plate 21 will fall naturally. This method can effectively separate iron ore and residual material, and has high separation efficiency, which is convenient for practical use.

[0035] In one embodiment, the transportation device 6 includes a first conveying platform 61 and a second conveying platform 62. The first conveying platform 61 is located inside the magnetic separation cylinder, and is used to carry the iron ore that falls after magnetic attraction and transport it to its output end. The width of the electromagnetic plate 21 is smaller than the width of the first conveying platform 61. The second conveying platform 62 is located inside and outside the magnetic separation cylinder, and is used to carry the residual material output by the magnetic separation cylinder and transport it to its output end. The second conveying platform 62 is provided with a bracket 7 extending outside the magnetic separation cylinder.

[0036] Such a design enables the naturally falling iron ore to fall onto the first conveyor platform 61, while the remaining material after separation will fall onto the second conveyor platform 62. The first conveyor platform 61 and the second conveyor platform 62 can transport them to the desired location. The first conveyor platform 61 and the second conveyor platform 62 mentioned above are both roller conveyors with conveyor belts, and this equipment is common knowledge in this field. Therefore, the specific structural composition and working principle will not be described in detail in this article.

[0037] In one embodiment, the second conveyor platform 62 is provided with a driving device for driving it to move, and the driving device may be a motor device. A transmission belt group 63 is provided at the moving ends of the first conveyor platform 61 and the second conveyor platform 62. The transmission belt group 63 includes two transmission wheels and a transmission belt provided on the two transmission wheels and coordinated with the transmission wheels.

[0038] In a specific implementation, one of the transmission wheels is arranged at the moving end of the first conveyor platform 61 (one of the rollers), and the other transmission wheel is arranged at the moving end of the second conveyor platform 62 (one of the rollers). Therefore, when the driving device drives the second conveyor platform 62 to work, it cooperates with the transmission belt group 63 to enable the first conveyor platform 61 to work at the same time, thereby completing the conveying task.

[0039] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] In addition, "plurality" means two or more.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
