Description

Technical Field

[0001] This application relates to the field of sorting technology, and in particular to a sorting device. Background Technology

[0002] Heavy minerals are a collective term for minerals with a specific gravity greater than 2.9, including hematite, magnetite, zircon, etc., and most heavy minerals are magnetic. In the pretreatment process of heavy mineral separation, it is necessary to separate heavy minerals from other low-density minerals. Related technologies typically employ manual separation or vibratory separation to separate heavy minerals from other low-density minerals. Manual separation generally involves manually shaking a washing pan containing minerals, using centrifugal force to sieve out the low-density minerals from the pan. Vibratory separation typically involves setting multiple baffles at intervals on an inclined plane, and using a shaking table to evenly shake the minerals on the inclined plane. The low-density minerals are carried away by the water flow, while the heavy minerals are blocked by the baffles and settle.

[0003] However, manual sorting is time-consuming, labor-intensive, and inefficient; the sorting effect of vibration sorting is not good and it cannot effectively remove some low-density minerals. Further screening under a manual microscope is required later, which is a cumbersome process; both of these methods require water flow and drying after mineral sorting, making the sorting process complicated and inefficient.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] See Figure 1 This application provides a sorting device. Optionally, the sorting device is used to sort minerals, that is, to sort samples as minerals.

[0025] For example, the sorting device includes a feed member 100, a first collector 200, a second collector 300, an air separator 500, and a magnetic separator 600. The feed member 100 is used to input the sorting sample, which falls from the discharge end 111 of the feed member 100 to form a falling path. At least a portion of the second collector 300 is located on the falling path, and the first collector 200 is located on one side of the falling path. The second collector 300 is arranged vertically below the first collector 200. The air separator 500 is arranged on the side of the falling path away from the first collector 200 and is used to blow light sand minerals in the sorting sample into the first collector 200. The magnetic separator 600 is arranged below the second collector 300 and is used to adsorb magnetic minerals in the sorting sample into the second collector 300 by its own magnetic force.

[0026] It is understandable that when the sample falls from the discharge end 111 of the feeder 100, on the one hand, the air separator 500 can blow the light sand minerals in the sample into the first collector 200, while the heavy sand minerals in the sample fall into the second collector 300 under their own gravity, thus achieving the purpose of separation. On the other hand, most heavy sand minerals are magnetic, and the magnetic separator 600 can also adsorb the magnetic heavy sand minerals in the sample into the second collector 300 through its own magnetic force. That is to say, the separation device in this application can achieve separation through both air force and magnetic force, which can improve the separation effect; the separation device is easy to operate and does not require drying, washing, and re-drying of the sample, simplifying the separation steps and improving the separation efficiency. Moreover, the separation device in this embodiment can also be used to separate mixtures including heavy sand minerals and magnetic minerals, broadening the application scenarios.

[0027] The following example illustrates the process: “The sorted samples include both light and heavy minerals, and all magnetic minerals are heavy minerals.”

[0028] Alternatively, in some embodiments, see Figure 1 and Figure 2 The first collecting component 200 includes a first feeding end 211, and the air outlet of the air separator 500 is located below the first feeding end 211, with the air outlet of the air separator 500 facing the first feeding end 211.

[0029] Understandably, the air outlet of the air separator 500 is located below the first feed end 211. When the air separator 500 blows the light sand minerals of the sorted sample to the first feed end 211 during the falling process, it needs to overcome the gravity of the light sand minerals. By controlling the air force of the air separator 500, the light sand minerals and heavy sand minerals can be separated to ensure the sorting effect.

[0030] Optionally, in some embodiments, the first collecting member 200 includes a first conveying mechanism, and a first feeding end 211 is disposed on the first conveying mechanism.

[0031] Optionally, the first conveying mechanism includes a first conveyor belt 210 and a first drive wheel 220. One end of the first conveyor belt 210 is a first feed end 211, and the first drive wheel 220 is connected to the first conveyor belt 210 to drive the first conveyor belt 210 to convey the light sand minerals at the first feed end 211. Optionally, the first conveyor belt 210 is inclined, and the first feed end 211 of the first conveyor belt 210 is lower than the first discharge end.

[0032] The air separator 500 blows the light sand minerals in the sorted sample to the first feed end 211, and outputs the sorted light sand minerals via the first conveyor belt 210 for further collection. It is understood that collecting the light sand minerals output from the first conveyor belt 210 does not affect the collection of the sorted light sand minerals at the first feed end 211; that is, sorting and collection can be carried out simultaneously, which can improve sorting efficiency and is also beneficial for sorting a larger number of samples.

[0033] Optionally, in some embodiments, the second collector 300 includes a second feed end 311 located on the falling path. With the second feed end 311 on the falling path, heavy minerals in the sorted sample can fall from the discharge end 111 of the feed member 100 to the second feed end 311, thereby collecting the heavy minerals in the sorted sample.

[0034] Optionally, in some embodiments, the second collecting member 300 includes a second conveying mechanism, a second feeding end 311 is disposed on the second conveying mechanism, and a magnetic separator 600 is disposed directly below the second feeding end 311.

[0035] Optionally, the second conveying mechanism includes a second conveyor belt 310 and a second drive wheel 320. One end of the second conveyor belt 310 is a second feed end 311, and the second drive wheel 320 is connected to the second conveyor belt 310 to drive the second conveyor belt 310 to convey the heavy sand minerals at the second feed end 311. Optionally, the second conveyor belt 310 is inclined, and the second feed end 311 of the second conveyor belt 310 is lower than the second discharge end. Optionally, the second conveyor belt 310 is parallel to the first conveyor belt 210.

[0036] The heavy minerals in the sorted sample fall to the second feed end 311 under the influence of their own gravity and the magnetic force of the magnetic separator 600. They are then output via the second conveyor belt 310 for further collection. It is understood that collecting the heavy minerals output from the second conveyor belt 310 does not affect the collection of the sorted heavy minerals at the second feed end 311; that is, sorting and collection can be performed simultaneously, improving sorting efficiency and facilitating the sorting of a larger number of samples. The magnetic separator 600 is positioned directly below the second feed end 311, which allows the magnetic force of the magnetic separator 600 to be superimposed with the gravity of the heavy minerals, enhancing the sorting effect.

[0037] Of course, the first collecting component 200 and the second collecting component 300 can also be collecting components such as hoppers, and no specific restrictions are made here.

[0038] Optionally, in some embodiments, the first collection member 200 includes a first conveying mechanism, and the second collection member 300 includes a second conveying mechanism, both of which are provided with a stop 400. The stop 400 is used to prevent light sand minerals in the first collection member 200 or heavy sand minerals in the second collection member 300 from falling out.

[0039] For example, the baffle 400 is a baffle plate. The first conveyor belt 210 is provided with multiple baffle plates at intervals along its length, and the second conveyor belt 310 is also provided with multiple baffle plates at intervals along its length. The number of baffle plates on the first conveyor belt 210 and the second conveyor belt 310, as well as the spacing between two adjacent baffle plates, can be set according to actual needs, and no specific restrictions are imposed here.

[0040] It is understandable that the first feed end 211 of the first conveyor belt 210 is lower than the first discharge end, and the second feed end 311 of the second conveyor belt 310 is lower than the second discharge end. Therefore, the conveying direction of the first conveyor belt 210 and the second conveyor belt 310 is from low to high. By setting multiple baffles at intervals along the length of the first conveyor belt 210 and the second conveyor belt 310, it is possible to prevent light sand minerals on the first conveyor belt 210 and heavy sand minerals on the second conveyor belt 310 from falling off during the conveying process.

[0041] Optionally, baffles may also be provided on both sides of the first conveyor belt 210 and both sides of the second conveyor belt 310, without specific restrictions.

[0042] Optionally, in some embodiments, the feed member 100 includes a third conveying mechanism, and the discharge end 111 of the feed member 100 is disposed on the third conveying mechanism.

[0043] For example, the third conveying mechanism includes a third conveyor belt 110 and a third drive wheel 120. One end of the third conveyor belt 110 is the discharge end 111 of the feed member 100. The third drive wheel 120 is connected to the third conveyor belt 110 to drive the third conveyor belt 110 to convey the sorted samples. Optionally, the third conveyor belt 110 is inclined, and the discharge end 111 of the third conveyor belt 110 is lower than the feed end. Optionally, the third conveyor belt 110 is also provided with multiple baffles at intervals along its length. The number of baffles on the third conveyor belt 110 and the spacing between two adjacent baffles can be set according to actual needs and are not specifically limited here.

[0044] It is understandable that the discharge end 111 of the third conveyor belt 110 is lower than the feed end. Therefore, the conveying direction of the third conveyor belt 110 is from high to low. By setting multiple baffles at intervals along the length of the third conveyor belt 110, the sorted samples on the third conveyor belt 110 can be prevented from falling during the conveying process.

[0045] Alternatively, in some embodiments, see Figure 1 The sorting device also includes a housing 710, which has a receiving cavity. The feed component 100, the first collecting component 200, the second collecting component 300, the air separator 500, and the magnetic separator 600 are all disposed in the receiving cavity.

[0046] For example, the first collector 200 is fixed in the receiving cavity by a first bracket 810, the bottom of the first bracket 810 being connected to the first collector 200, and the top of the first bracket 810 being connected to the top wall of the receiving cavity. The second collector 300 is fixed in the receiving cavity by a second bracket 820, the top of the second bracket 820 being connected to the second collector 300, and the bottom of the second bracket 820 being connected to the bottom wall of the receiving cavity. The feeder 100 is fixed in the receiving cavity by a third bracket 830, the top of the third bracket 830 being connected to the top wall of the outer casing 710, and the bottom of the third bracket 830 being connected to the feeder 100.

[0047] Optionally, two of each of the first bracket 810, the second bracket 820, and the third bracket 830 are provided. It is understood that the specific number and location of the first bracket 810, the second bracket 820, and the third bracket 830 can be set according to actual needs, and no specific restrictions are imposed here.

[0048] Alternatively, in some embodiments, see Figure 3 The outer casing 710 is provided with a wind power knob 720 and a magnetic knob 730. The wind power knob 720 is electrically connected to the wind selector 500, and the magnetic knob 730 is electrically connected to the magnetic selector 600.

[0049] Optionally, see Figure 2 The air separator 500 includes a blower 510 and an air duct 520. One end of the air duct 520 is connected to the blower 510, and the other end of the air duct 520 is provided with an air outlet. Optionally, a wind power knob 720 is electrically connected to the blower 510. By rotating the wind power knob 720, the wind power of the blower 510 can be adjusted, thereby enabling the separation of minerals of different masses in the sample.

[0050] Optionally, the blower 510 is fixed at the bottom of the accommodating cavity, and the sorting device also includes a fourth bracket 840, which is used to fix the air duct 520, thereby ensuring the stability of the airflow direction of the air outlet of the air duct 520.

[0051] Optionally, see Figure 3The housing 710 is also provided with an air inlet 713 and an air outlet 714. The air inlet 713 corresponds to the position of the blower 510 to allow air to enter the blower 510. Optionally, the air inlet 713 is located at the lower left corner of the front side wall of the housing 710, and the air outlet 714 is located at the upper right corner of the right side wall of the housing 710. It is understood that the specific positions of the air inlet 713 and the air outlet 714 can be adjusted according to actual needs, and no specific restrictions are imposed here.

[0052] Optionally, the sorting device also includes a power supply, and the magnetic separator 600 includes an electromagnet electrically connected to the power supply. A magnetic knob 730 is electrically connected to the electromagnet. By rotating the magnetic knob 730, the magnetic force of the electromagnet can be adjusted, thereby enabling the sorting of minerals with different magnetic flux in the sample.

[0053] Optionally, the housing 710 is also equipped with a first display screen and a second display screen. The first display screen is electrically connected to the blower 510 and is used to display the wind force value of the blower 510. The second display screen is electrically connected to the electromagnet and is used to display the magnetic force value of the electromagnet. Optionally, the blower 510, the first power wheel 220, the second power wheel 320, the third power wheel 120, the first display screen, and the second display screen are also electrically connected to a power source.

[0054] Optionally, the housing 710 is also provided with a power switch 740 and a timer 750. The power switch 740 is electrically connected to the power supply to control the power supply to turn on and off. The timer 750 is also connected to the power supply to perform timed control of the power supply, thereby controlling the sorting time.

[0055] For example, the wind knob 720, the magnetic knob 730, the power switch 740, the timer 750, the first display screen and the second display screen are all disposed on the front outer side wall of the housing 710.

[0056] Optionally, in some embodiments, the housing 710 is provided with an inlet 711 and an outlet 712, the inlet end of the feed member 100 is connected to the inlet 711, the first collector 200 includes a first outlet end, the second collector 300 includes a second outlet end, and both the first outlet end and the second outlet end are connected to the outlet 712.

[0057] For example, the feed inlet 711 is located on the left side wall of the housing 710, and the discharge outlet 712 is located on the right side wall of the housing 710. The first discharge end is located at the end of the first conveyor belt 210 away from the first feed end 211, the second discharge end is located at the end of the second conveyor belt 310 away from the second feed end 311, and the feed end of the feeder 100 is located at the end of the third conveyor belt 110 away from the discharge end 111.

[0058] For example, this application embodiment also provides a method of using a sorting device, including the following steps: turning on the power switch 740 to start the operation of the feed member 100, the first collector 200, the second collector 300, the air separator 500 and the magnetic separator 600.

[0059] Rotate the wind force knob 720 to adjust the wind force of the wind selector 500 to the first preset value, rotate the magnetic force knob 730 to adjust the magnetic force of the magnetic selector 600 to the second preset value, and use the timer 750 to preset the sorting time.

[0060] The sorted sample with a particle size of 0.063mm-0.25mm is fed into the feed unit 100 through the feed inlet 711. The sorted sample falls from the discharge end 111 of the feed unit 100. The air separator 500 blows the light sand minerals (such as quartz, mica, feldspar, etc.) in the sorted sample into the first collection unit 200, while the heavy sand minerals (such as hematite, magnetite, barite, etc.) in the sorted sample fall into the second collection unit 300 under the action of their own gravity and the magnetic force of the magnetic separator 600, until the preset sorting time ends.

[0061] The separated heavy and light minerals are collected separately, and then the purity of the heavy and light minerals is visually estimated under a microscope. The separation is considered complete when the purity reaches 98% or higher.
