Description

Technical Field

[0001] This invention relates to the field of wet magnetic separator technology, specifically a wet magnetic separator. Background Technology

[0002] A wet magnetic separator is a device that uses magnetic differences to separate minerals in a liquid medium. It separates magnetic minerals by attracting them to the surface of a magnetic drum using magnetic force. It is mainly used for the beneficiation and purification of magnetic minerals such as iron ore and manganese ore, as well as for iron removal from coal and non-metallic minerals, and wastewater treatment.

[0003] Existing wet magnetic separators have gradually revealed shortcomings during use, mainly in the following aspects: First, there is the inclusion of non-magnetic substances. Specifically, during the operation of a wet magnetic separator, the permanent magnet inside the magnetic drum continuously generates a strong magnetic field. When the surface of the magnetic drum passes through a liquid medium containing both magnetic and non-magnetic substances, the magnet inside the drum quickly adsorbs the magnetic substances onto the surface of the drum due to its magnetism. This adsorption process is extremely fast due to the strong force of the magnetic field on the magnetic particles. Because the solid particles in the slurry are densely distributed, and some non-magnetic particles are small in size and physically adhere to the magnetic particles, some non-magnetic substances will be mixed in with the adsorbed magnetic substances and adhere to the surface of the magnetic drum. These mixed non-magnetic impurities will dilute the purity of the magnetic substances, thereby affecting the magnetic separation effect on magnetic minerals.

[0004] Secondly, the magnetic mineral sorting process is cumbersome. Specifically, magnetic minerals can be classified into different grades such as strong magnetic, medium magnetic, and weak magnetic based on their differences in magnetic strength. Minerals of different magnetic grades have different values ​​and uses in subsequent processing and utilization. Therefore, after preliminary magnetic separation, magnetic minerals need to undergo precise grade sorting. In the actual mineral processing flow, magnetic minerals first undergo coarse screening using a wet magnetic separator to remove most of the non-magnetic impurities. Subsequently, these coarsely screened magnetic minerals need to be transferred to a dedicated sorting machine for fine grade sorting. This process involves multiple stages of collection, transfer, and supporting control operations, which lengthens the overall process from coarse screening to grade sorting of magnetic minerals, thus making the magnetic mineral sorting process cumbersome.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a wet magnetic separator that can effectively remove non-magnetic minerals mixed in with magnetic minerals in a liquid medium during the magnetic separation process, significantly solving the problem of non-magnetic mineral inclusions and thus greatly improving the overall purity of magnetic minerals. This wet magnetic separator can simultaneously achieve fine separation of magnetic minerals while completing magnetic separation and discharging them outwards. It integrates the traditional multi-stage process into one step, greatly simplifying the separation process and significantly improving the separation efficiency.

[0007] To address the above problems, the present invention provides the following technical solution: A wet magnetic separator includes a base, an outer roller rotatably mounted on the top of the base, and an inner roller rotatably mounted inside the outer roller, in frictional contact with it. Two material collection troughs are evenly distributed on the outer wall of the inner roller. Waste discharge troughs are connected to both sides of the material collection troughs inside the inner roller, with one end of each waste discharge trough penetrating the inner roller. Several sealing plates are vertically slidable inside the inner roller, with one end extending into the waste discharge trough and in frictional contact with the inner roller. Two lower mounting plates are evenly distributed inside the inner roller and moved radially therefrom. Lower magnets are fixedly mounted on the lower mounting plates. An insert is provided through the lower outer wall of the outer roller. The outer roller has a fixed box that extends through it. Inside the fixed box, an upper mounting plate and a partition are vertically slidably arranged and in frictional contact with it. An upper magnet is fixedly installed at the bottom of the upper mounting plate. The fixed box has several drainage holes on its inner wall and several water outlet holes on its other inner wall. A discharge trough extends through the end of the fixed box and a baffle that slides through the discharge trough. One end of the outer roller has several connecting grooves. The outer wall of the outer roller has several waste discharge channels that communicate with the connecting grooves. A material box is vertically lifted and lowered below the outer roller.

[0008] As an optimized solution, the material box is equipped with a drive shaft that rotates inside, and a number of stirring blades are fixed on the outer wall of the drive shaft. The upper end and the bottom of the material box are respectively connected to a feed pipe and a discharge valve.

[0009] As an optimized solution, a drive motor is fixedly installed at the end of the material box, the output shaft of the drive motor is fixedly connected to the drive shaft, and a plurality of lifting and telescopic cylinders are fixedly installed on the top of the base, with the telescopic ends of the lifting and telescopic cylinders fixedly connected to the material box.

[0010] As an optimized solution, an inner support plate is fixedly provided on the inner wall of the inner roller. Several inner fixed plates, a first built-in telescopic cylinder and a second built-in telescopic cylinder are fixedly provided on the top and bottom of the inner support plate. The closing plate is slidably connected to the inner fixed plate. One end of the closing plate is flush with the inner wall of the material collection trough. The telescopic end of the first built-in telescopic cylinder is fixedly connected to the lower mounting plate. The telescopic end of the second built-in telescopic cylinder is fixedly connected to the closing plate.

[0011] As an optimized solution, the fixed box is equipped with a water flow channel and two water passage channels inside. The drain hole is connected to the water passage channel, and the water outlet is connected to the water flow channel. Both the water passage channel and the water flow channel are connected to an external water source through water pipes.

[0012] As an optimized solution, a number of drive telescopic cylinders and control telescopic cylinders are fixedly installed on the top of the fixed box. The telescopic end of the drive telescopic cylinder is fixedly connected to the upper mounting plate, and the telescopic end of the control telescopic cylinder passes through the upper mounting plate and the upper magnet and is fixedly connected to the partition.

[0013] As an optimized solution, a number of electrically controlled telescopic cylinders are fixedly installed at the end of the fixed box, and the telescopic ends of the electrically controlled telescopic cylinders are fixedly connected to the baffle.

[0014] As an optimized solution, the base is fixedly provided with a first support plate and a second support plate on both sides of the outer roller. The outer roller is fixedly provided with a through-hole rotating cylinder at both ends. The rotating cylinder passes through the first support plate and is rotatably connected to the first support plate. The inner roller is fixedly provided with a rotating shaft at both ends. One end of the rotating shaft passes through the rotating cylinder and is rotatably connected to the second support plate. The rotating shaft is rotatably connected to the rotating cylinder.

[0015] As an optimized solution, a first servo motor is fixedly installed at the end of one of the first support plates. The output shaft of the first servo motor passes through the first support plate and is rotatably connected to the first support plate. Gears are fixedly fitted on both the output shaft of the first servo motor and the outer wall of the rotating cylinder. The two gears mesh with each other. A second servo motor is fixedly installed at the end of one of the second support plates. The output shaft of the second servo motor is fixedly connected to the rotating shaft.

[0016] As an optimized solution, the top of the material bin and the bottom of the fixed box are both arc-shaped structures, and the upper magnet, lower magnet and partition are all arc-shaped.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The lifting telescopic cylinder moves the material box upwards, and the top of the material box passes through the slot and inserts into the collection trough, abutting against the inner roller. At this time, the top opening of the material box is closed by the inner roller. Liquid medium can be added or discharged into the material box through the feed pipe and discharge valve. When the top opening of the material box is closed by the inner roller, the inside of the material box is full of liquid medium. The first built-in telescopic cylinder moves the lower magnet downwards until the lower magnet contacts the inner roller. The drive motor drives the stirring blades to rotate, thereby agitating the liquid medium. Under the attraction of the lower magnet, the magnetic material in the liquid medium is attracted to the collection trough below. After a certain amount of magnetic material accumulates in the collection trough, the discharge valve discharges part of the liquid medium, causing the liquid level inside the material box to drop. The material box resets and exits the outer roller. The second servo motor drives the inner roller to rotate 180°, and the upper and lower collection troughs are swapped. The lower magnet located at the top moves downwards, thereby releasing the attraction of magnetic material in the collection trough. The telescopic cylinder controls the partition to move downwards to the lowest position (e.g., Figure 6 As shown), at this point, the bottom of the partition is flush with the inner wall of the outer roller. The drive telescopic cylinder moves the upper magnet downwards until it contacts the partition. The magnetic material in the upper collection trough is attracted to the bottom of the partition. Then, the partition and the upper magnet move upwards synchronously to the preset throwing height. Then, the upper magnet quickly moves upwards to reset and separate from the partition, thereby releasing the attraction of the material at the bottom of the partition. The material falls into the collection trough, creating a tumbling effect. The relative position of the material changes, and then the partition and the upper magnet re-attract the material in the collection trough and raise it again to the preset throwing height (as shown). Figure 8 As shown in the figure, some non-magnetic materials remain inside the collection trough. At this time, the second built-in telescopic cylinder drives the sealing plate to slide downward. The collection trough above is connected to the waste discharge trough. External water is discharged through the drainage hole, thereby flushing the non-magnetic materials in the collection trough above. The non-magnetic materials are discharged to the outside for collection through the waste discharge trough, the connecting trough and the waste discharge channel. The above process of screening non-magnetic materials is repeated to remove non-magnetic materials mixed in with magnetic materials. This wet magnetic separator can effectively remove non-magnetic minerals mixed in with magnetic minerals in the process of magnetic separation of magnetic minerals in liquid media, which significantly solves the problem of non-magnetic mineral inclusions, thereby greatly improving the overall purity of magnetic minerals. 2. After the non-magnetic materials are removed, the partition moves downward to its lowest position, driving the telescopic cylinder to move the upper magnet downward to the first sorting height. At this time, the upper magnet is far from the magnetic materials in the upper collection trough. The magnetic materials with high magnetic strength in the collection trough are attracted to the bottom of the partition. Then, the partition moves upward until it contacts the upper magnet and moves together with the upper magnet to the discharge height (at this time, the partition is above the water outlet). The first servo motor drives the outer roller and the fixed box to rotate 90° (e.g., Figure 9As shown in the figure, at this time, the lower part of the discharge tank is opened, the upper magnet separates from the partition and releases the adsorption of magnetic materials. At the same time, the external water source is discharged through the water outlet and washes the surface of the partition. The magnetic materials are discharged to the outside through the discharge tank for collection. By repeating the above discharge operation and controlling the distance between the upper magnet and the magnetic materials in the collection tank, the magnetic materials with different magnetic intensities can be separated. In the process of completing magnetic separation and discharging magnetic minerals to the outside, this wet magnetic separator can simultaneously achieve fine separation of magnetic minerals, integrating the traditional multi-stage process into one step, greatly simplifying the separation process and significantly improving the separation efficiency. 3. During the process of cleaning the non-magnetic substances mixed in with the magnetic substances in the upper collection trough, the top of the material box passes through the slot and is inserted into the collection trough below the inner roller. The above adsorption operation of magnetic substances in the liquid medium is repeated to complete the adsorption of the next batch of magnetic substances. 4. During the adsorption process of magnetic materials in the material tank, the stirring blades can agitate the liquid medium in the material tank, thereby enabling the magnetic materials in the liquid medium to be better adsorbed.

[0029] The base 1 is fixedly provided with a first support plate 13 and a second support plate 14 on both sides of the outer roller 3. The outer roller 3 is fixedly provided with a through rotating cylinder 9 at both ends. The rotating cylinder 9 passes through the first support plate 13 and is rotatably connected to the first support plate 13. The inner roller 31 is fixedly provided with a rotating shaft 10 at both ends. One end of the rotating shaft 10 passes through the rotating cylinder 9 and is rotatably connected to the second support plate 14.

[0030] One of the first support plates 13 has a first servo motor 12 fixedly mounted at its end.

[0031] The top of the material bin 2 and the bottom of the fixed box 6 are both arc-shaped structures, and the upper magnet 23, the lower magnet 37 and the partition 22 are all arc-shaped.

[0032] The working principle of this device is as follows: The lifting telescopic cylinder 16 drives the material box 2 to move upward. The top of the material box 2 passes through the slot 19 and inserts into the collection trough 36, abutting against the inner roller 31. At this time, the top opening of the material box 2 is closed by the inner roller 31. Liquid medium can be added to or discharged into the material box 2 through the feed pipe 18 and the discharge valve 17. When the top opening of the material box 2 is closed by the inner roller 31, the inside of the material box 2 is full of liquid medium. The first built-in telescopic cylinder 39 drives the lower magnet 37 to move downward until the lower magnet 37 contacts the inner roller 31. The drive motor 15 drives the stirring blade 42 to rotate, thereby stirring the liquid. The medium is agitated, and under the attraction of the lower magnet 37, the magnetic material in the liquid medium is attracted to the lower collection tank 36. After a certain amount of magnetic material accumulates in the collection tank 36, the discharge valve 17 discharges part of the liquid medium, causing the liquid level inside the tank 2 to drop. The tank 2 resets and exits the outer roller 3. The second servo motor 11 drives the inner roller 31 to rotate 180°, and the upper and lower collection tanks 36 are switched. The lower magnet 37, located at the top, moves downward to release the attraction of the magnetic material in the collection tank 36. The telescopic cylinder 26 controls the partition 22 to move downward to the lowest position (e.g., Figure 6 As shown), at this time, the bottom of the partition 22 is flush with the inner wall of the outer roller 3. The drive telescopic cylinder 25 drives the upper magnet 23 to move downwards until it contacts the partition 22. The magnetic material in the upper collection trough 36 is attracted to the bottom of the partition 22. Then, the partition 22 and the upper magnet 23 move upwards synchronously to the preset throwing height. Then, the upper magnet 23 moves upwards quickly to reset and separate from the partition 22, thereby releasing the attraction of the material at the bottom of the partition 22. The material falls into the collection trough 36, forming a tumbling effect. The relative position of the material changes. Then, the partition 22 and the upper magnet 23 re-attract the material in the collection trough 36 and raise it again to the preset throwing height (as shown). Figure 8 As shown), some non-magnetic materials remain inside the collection trough 36. At this time, the second built-in telescopic cylinder 40 drives the sealing plate 35 to slide downward. The collection trough 36 located above is connected to the waste discharge trough 34. External water is discharged through the drain hole 30, thereby flushing the non-magnetic materials in the collection trough 36 above. The non-magnetic materials are discharged to the outside for collection through the waste discharge trough 34, the connecting trough 20 and the waste discharge channel 21. The above process of screening non-magnetic materials is repeated to remove non-magnetic materials mixed in with magnetic materials. This wet magnetic separator can effectively remove non-magnetic minerals mixed in with magnetic minerals in the process of magnetic separation of magnetic minerals in liquid media, which significantly solves the problem of non-magnetic mineral inclusions, thereby greatly improving the overall purity of magnetic minerals. After the non-magnetic material is removed, the partition 22 moves downward to its lowest position, driving the telescopic cylinder 25 to move the upper magnet 23 downward to the first sorting height. At this time, the upper magnet 23 is far from the magnetic material in the upper collection trough 36, and the magnetic material with high magnetic strength in the collection trough 36 is attracted to the bottom of the partition 22. Then, the partition 22 moves upward until it contacts the upper magnet 23 and moves together with the upper magnet 23 to the discharge height (at this time, the partition 22 is above the water outlet 27). The first servo motor 12 drives the outer roller 3 and the fixed box 6 to rotate 90° (e.g., Figure 9 As shown), at this time, the lower part of the discharge tank 7 is opened, the upper magnet 23 separates from the partition plate 22 and releases the adsorption of magnetic materials. At the same time, external water is discharged through the water outlet 27 and washes the surface of the partition plate 22. Magnetic materials are discharged to the outside through the discharge tank 7 for collection. The above discharge operation is repeated and the distance between the upper magnet 23 and the magnetic materials in the collection tank 36 is controlled to achieve the separation of magnetic materials with different magnetic intensities. In the process of completing magnetic separation and discharging magnetic minerals to the outside, this wet magnetic separator can simultaneously achieve fine separation of magnetic minerals, integrating the traditional multi-stage process into one step, greatly simplifying the separation process and significantly improving the separation efficiency. During the process of cleaning the non-magnetic substances mixed in the magnetic material in the upper collection trough 36, the top of the material box 2 passes through the slot 19 and is inserted into the collection trough 36 below the inner roller 31. The above adsorption operation of magnetic substances in the liquid medium is repeated to complete the adsorption of the next batch of magnetic substances. During the adsorption process of magnetic materials in the material tank 2, the stirring blades 42 can agitate the liquid medium in the material tank 2, thereby enabling the magnetic materials in the liquid medium to be better adsorbed.
