Technical Field

[0001] The present invention relates to the technical field of magnetic separation devices, in particular to a multi-layer superconducting magnetic separation device with multiple columns of separation cavities and a screening method. Background Art

[0002] Superconducting magnetic separation device is a strong magnetic field magnetic separation device that uses superconductor to wind magnetic coils. Since Bennetts invented the superconducting magnetic separation device in 1970, the United States, Britain, Germany and other countries have also carried out research and development of superconducting magnetic separation devices and have put them into industrial application. Superconducting magnetic separation devices are generally divided into two categories: open gradient superconducting magnetic separation devices and high gradient superconducting magnetic separation devices.

[0003] The existing ores are complex in types and contain linear materials with different precisions, which makes it impossible to distinguish between high-precision ores and low-precision ores. The utilization rate of the ore is reduced, resulting in a waste of resources. Therefore, a superconducting magnetic separation device and screening method are needed to solve the above problems. Summary of the invention

[0007] The box body serves as an installation base and is used to connect the feed port, the transmission device and the dumping device. The ore is put into the box body through the feed port. Different types of ores are screened by setting up several groups of layer transmission devices. Different ores are collected by setting up several groups of dumping devices. The ore is directly collected by setting the dumping device below the transmission device.

[0008] Furthermore, the feed inlet includes two inclined plates, the cross-sectional area of ​​the lower end of the feed inlet is smaller than the cross-sectional area of ​​the upper end, and the feed inlet is fastened to the top of the box body.

[0009] The feed port is used to feed ore. The feed port is set so that the lower cross-sectional area is smaller than the upper cross-sectional area to prevent ore from splashing, causing casualties and resource loss. The feed port is set in the middle of the box body, close to the active transmission wheel, to effectively prevent the ore from falling directly onto the second conveyor belt from the gap, causing the ore to directly enter the storage chamber, resulting in confusion in the ore category and containing non-magnetic ore, causing resource loss in the subsequent process of refining magnetic materials.

The end of the conveying stroke of the pouring device is facing the storage chamber, and the screened ores can be directly collected in columns. The box body is provided with multiple layers of magnetic separation chambers, and the magnetic force gradually increases from top to bottom. Small-volume and weak-magnetic ores are screened out through the first layer of magnetic separation chambers, and the unselected large-volume and strong-magnetic ores or non-magnetic ores fall into the next layer under the action of gravity. Through the setting of multiple layers of magnetic separation chambers, ores with different magnetism, different volumes, and different precisions are screened, and the non-magnetic ores fall into the waste chamber facing the end of the conveying stroke of the bottom transmission device 3 under the action of gravity, making full use of ore resources and simplifying the subsequent refining work.

[0012] Furthermore, the transmission device includes a first transmission wheel group, a first conveyor belt and a first motor. The first motor and the magnetic selection chamber are tightly connected, the output end of the first motor and the first transmission wheel group are rotationally connected, the first transmission wheel group and the magnetic selection chamber are rotationally connected, and the first conveyor belt is sleeved on the outer ring of the first transmission wheel group.

The second conveyor belt and the second transmission wheel group are arranged below the scraping mechanism, so that the second conveyor belt directly transports the scraped ore to the storage chamber connected to the magnetic separation chamber.

[0016] Furthermore, the first transmission wheel group includes an active transmission wheel, a driven transmission wheel and a fixed shaft, the first motor and the active transmission wheel are tightly connected, the fixed shaft and the active transmission wheel are tightly connected, the fixed shaft and the driven transmission wheel are tightly connected, the active transmission wheel and the driven transmission wheel are tiltedly arranged, the active transmission wheel is located at the high end, and the driven transmission wheel is located at the low end, the first conveyor belt is mounted on the outer rings of the active transmission wheel and the driven transmission wheel, and the feeding direction of the first conveyor belt is from the high end to the low end.

[0017] The first motor outputs torque to the active transmission wheel, causing the active transmission wheel to rotate. The active transmission wheel outputs torque to the given shaft, and the given shaft outputs torque to the driven transmission wheel, thereby driving the driven transmission wheel to rotate. The active transmission wheel is set at the high end to make the conveying process of the first conveyor belt smoother and reduce the impact of the falling ore on the conveying process of the first conveyor belt. The inclined setting of the active transmission wheel and the driven transmission wheel can screen out the ore that cannot be adsorbed.

[0018] Furthermore, the first conveyor belt is composed of a plurality of magnetic rods, which are hingedly connected. The magnetic rods are semi-cylindrical, with arc shapes facing outwards, and the magnetic forces of the magnetic rods increase from top to bottom.

[0033] The box body 2 serves as an installation base and is used to connect the feed port 1, the transmission device 3 and the dumping device 4. The ore is put into the box body 2 through the feed port 1. Different types of ores are screened by setting up several groups of layer transmission devices 3.

[0035] The feed port 1 is used to put in ore, and the feed port 1 is set so that the lower cross-sectional area is smaller than the upper cross-sectional area to prevent ore splashing, causing casualties and resource loss. The feed port 1 is set in the middle of the box body 2, close to the active transmission wheel 311, to effectively prevent the ore from falling directly from the gap onto the second conveyor belt 43, causing the ore to directly enter the storage chamber 22, causing the ore category to be confused and contain non-magnetic ore, causing resource loss in the subsequent process of refining magnetic materials.

[0036] like Figure 1-2As shown, the box body 2 is provided with a magnetic separation chamber 21, a storage chamber 22 and a waste chamber 23. There are several magnetic separation chambers 21, and the several groups of magnetic separation chambers 21 are arranged in sequence from top to bottom. A storage chamber 22 is provided on one side of the magnetic separation chamber 21, and a waste chamber 23 is provided on one side of the bottom magnetic separation chamber 21.

Through the setting of the multi-layer magnetic separation chamber 21, ores with different magnetism, different volumes and different precisions are screened, and the non-magnetic ores fall into the waste chamber 23 at the end of the conveying stroke of the bottom transmission device 3 due to gravity, which makes full use of the ore resources and simplifies the subsequent refining work.

[0038] like Figure 1-2 As shown, the transmission device 3 includes a first transmission wheel group 31, a first conveyor belt 32 and a first motor 33. The first motor 33 is firmly connected to the magnetic separation chamber 21. The output end of the first motor 33 is rotatably connected to the first transmission wheel group 31. The first transmission wheel group 31 is rotatably connected to the magnetic separation chamber 21. The first conveyor belt 32 is sleeved on the outer ring of the first transmission wheel group 31.

[0039] The first motor 33 is installed and fixed through the magnetic separation chamber 21. The first motor 33 is used to output torque to drive the first transmission wheel group 31 to transmit. The first transmission wheel group 31 is supported by double-end rotation through the wall of the magnetic separation chamber 21, thereby driving the first conveyor belt 32 to transmit. When the ore falls on the first conveyor belt 32, the ore is driven forward to facilitate the transportation and magnetic separation of the ore.

[0040] like Figure 1-2As shown, the material pouring device 4 includes a scraping mechanism 41, a second transmission wheel group 42, a second conveyor belt 43 and a second motor 44. The scraping mechanism 41 is tightly connected to the magnetic separation chamber 21, the second motor 44 is tightly connected to the magnetic separation chamber 21, the output end of the second motor 44 is tightly connected to the second transmission wheel group 42, the second conveyor belt 43 is sleeved on the outer ring of the second transmission wheel group 42, and the feeding direction of the second conveyor belt 43 is from the magnetic selection chamber 21 to the receiving chamber 22.

[0041] The unloading device 4 is used to recycle and summarize different types of ores. The scraping mechanism 41 is used to scrape off the ore adsorbed on the first conveyor belt 32. The second motor 44 serves as a power source to drive the second transmission wheel group 42 to rotate. The second transmission wheel group 42 drives the second conveyor belt 43 to rotate. The second conveyor belt 43 and the second transmission wheel group 42 are arranged below the scraping mechanism 41, so that the second conveyor belt 43 directly transports the scraped ore to the storage chamber 22 connected to the magnetic separation chamber 21.

[0042] like Figure 2-Figure 3 As shown, the first transmission wheel group 31 includes a driving transmission wheel 311, a driven transmission wheel 312 and a fixed shaft 313, the first motor 33 and the driving transmission wheel 311 are tightly connected, the fixed shaft 313 and the driving transmission wheel 311 are tightly connected, the fixed shaft 313 and the driven transmission wheel 312 are tightly connected, the driving transmission wheel 311 and the driven transmission wheel 312 are tilted, the driving transmission wheel 311 is located at the high end, and the driven transmission wheel 312 is located at the low end, the first conveyor belt 32 is sleeved on the outer rings of the driving transmission wheel 311 and the driven transmission wheel 312, and the feeding direction of the first conveyor belt 32 is from the high end to the low end.

[0043] The first motor 33 outputs torque to the active transmission wheel 311, so that the active transmission wheel 311 rotates. The active transmission wheel 311 outputs torque to the fixed shaft 313, and the fixed shaft 313 outputs torque to the driven transmission wheel 312, thereby driving the driven transmission wheel 312 to rotate. The active transmission wheel 311 is set at the high end to make the conveying process of the first conveyor belt 32 smoother and reduce the impact of the falling ore on the conveying process of the first conveyor belt 32. The active transmission wheel 311 and the driven transmission wheel 312 are tilted to screen out the ore that cannot be adsorbed.

[0044] like Figure 2-Figure 3 As shown, the first conveyor belt 32 is composed of a plurality of magnetic rods 321, which are hingedly connected. The magnetic rods 321 are semi-cylindrical, and the arc shape of the magnetic rods 321 faces outward. The magnetic force of the magnetic rods 321 increases from top to bottom.

[0045] The magnetic rod 321 is mainly used to absorb magnetic ores. Several magnetic rods 321 are connected by hinges to form a complete first conveyor belt 32, which can be flexibly rotated on the first transmission wheel set 31. The gradual increase of the magnetic rods 321 can screen out ores with weak to strong magnetism.

[0046] like Figure 2-Figure 3 As shown, the scraping mechanism 41 includes a scraper 411 and a connecting rod 412 . The connecting rod 412 and the magnetic separation chamber 21 are tightly connected. The scraper 411 and the connecting rod 412 are tightly connected.

[0047] The scraping mechanism 41 is arranged on one side of the active transmission wheel 311. The scraper 411 is used to scrape off the ore adsorbed on the magnetic rod 321. The connecting rod 412 is used to fix the scraper 411. The scraper 411 is made of a non-magnetic and compact material to prevent the scraper 411 from being adsorbed on the ore and the scraper 411 from breaking.

[0048] like Figure 1 to Figure 5 As shown, a screening method of a multi-layer superconducting magnetic separation device having multiple columns of separation cavities comprises the following steps:

[0049] 1. The ore enters the magnetic separation chamber 21 through the feed port 1;

[0050] 2. The box body 2 is provided with a multi-layer magnetic separation chamber 21. The first conveyor belt 32 is firmly connected to the magnetic separation chamber 21. The first conveyor belt 32 is composed of a plurality of magnetic rods 321 connected by hinges. The magnetic force of the magnetic rods 321 is gradually set from top to bottom to screen the ore in layers.

[0051] The ore enters the magnetic separation chamber 21 from the feed port 1 and falls on the first conveyor belt 32. The magnetic ore is adsorbed on the magnetic rod 321 of the first conveyor belt 32. The ore with no magnetism or very weak magnetism and the ore with large volume and strong magnetism that cannot be adsorbed fall into the next layer due to gravity. The magnetic force of the multi-layer magnetic separation chamber 21 gradually increases from top to bottom. Ores with different magnetism, different volumes and different precisions are adsorbed on the magnetic rods 321 of different layers. The ore with no magnetism or very weak magnetism finally falls into the waste chamber 23 due to gravity.

[0052] 3. The box body 2 is provided with multiple rows of storage chambers 22. The scraping mechanism 41 and the magnetic separation chamber 21 are tightly connected. The scraping mechanism 41 is used to collect the ore in columns.

[0053] The ore enters the magnetic separation chamber 21 from the feed port 1 and falls on the first conveyor belt 32. The magnetic ore is adsorbed on the magnetic rod 321 of the first conveyor belt 32. When the ore is transported to the end of the active transmission wheel 311, it is scraped off by the scraper 411 in the scraping mechanism 41. The scraped ore falls on the second conveyor belt 43 and is transported to the storage chamber 22 connected to the magnetic separation chamber 21. The ores magnetically selected from different layers are transported to the storage chambers 22 in different columns.

[0054] 4. After multi-layer magnetic separation and multi-column storage, the remaining waste falls into the waste cavity 23 of the lowest layer.

[0055] The working principle of the present invention is as follows: during magnetic separation, the ore entering from the feed port 1 enters the magnetic separation chamber 21 under the action of gravity and falls on the first conveyor belt 32. The first motor 33 provides power to drive the first transmission wheel group 31 to rotate. The first transmission wheel group 31 drives the first conveyor belt 32 to rotate. The first transmission wheel group 31 is placed obliquely, the active transmission wheel 311 is located at the high end, and the driven transmission wheel 312 is located at the low end. The first conveyor belt 32 is sleeved on the outer rings of the active transmission wheel 311 and the driven transmission wheel 312. The feeding direction of the first conveyor belt 32 is from the high end to the low end. The magnetic ore is adsorbed on the magnetic rod 321 of the first conveyor belt 32. The ore that is not magnetic or has extremely weak magnetism and the ore that is large in size and has strong magnetism and cannot be adsorbed fall into the next layer of the magnetic separation chamber 21 under the action of gravity, and the magnetic separation chamber 21 is filled with the magnetic material. It is arranged into several layers and the magnetic force gradually increases from top to bottom. The magnetic force of the magnetic stick 321 on the first conveyor belt 32 of different layers is changed to realize the process of gradually increasing the magnetic force from top to bottom, and ores of different volumes, different magnetic properties and different precisions are screened out. The magnetic ores adsorbed on the magnetic stick 321 are scraped off by the scraper 411, and the scraped ores fall on the second conveyor belt 43. The second conveyor belt 43 is sleeved on the outer ring of the second transmission wheel group 42, and the second motor 44 provides power to drive the second transmission wheel group 42 to rotate, and the second transmission wheel group 42 drives the second conveyor belt 43 to rotate. The feeding direction is from the magnetic separation chamber 21 to the storage chamber 22. The ores screened out from different layers are finally transported to the storage chambers 22 corresponding to different columns, and the ores with no magnetism or very weak magnetism finally fall into the waste chamber 23 due to gravity.
