Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wet magnetic separators, in particular to a wet magnetic separator. BACKGROUND

[0002] The wet magnetic separator is a device for separating minerals in a liquid medium by using the difference in magnetism. It separates the magnetic minerals from the non-magnetic minerals by attracting the magnetic minerals to the surface of the magnetic cylinder. It is mainly used for the beneficiation and purification of magnetic minerals such as iron ore and manganese ore, as well as for the removal of iron from coal, non-metallic minerals, wastewater treatment, etc.

[0003] The existing wet magnetic separator has some shortcomings in use, mainly in the following aspects:

[0004] First, non-magnetic substances are mixed. Specifically, during the operation of the wet magnetic separator, the permanent magnets inside the magnetic cylinder continuously generate a strong magnetic field. When the surface of the magnetic cylinder passes through a liquid medium containing magnetic and non-magnetic substances, the magnets inside the magnetic cylinder quickly attract the magnetic substances to the surface of the magnetic cylinder due to their magnetic properties. This adsorption process is very fast due to the strong magnetic force on the magnetic particles. Due to the dense distribution of solid particles in the ore slurry, some non-magnetic particles are small in size and physically adhere to the magnetic particles, so some non-magnetic substances will be mixed with the adsorbed magnetic substances and attached to the surface of the magnetic cylinder. These mixed non-magnetic impurities will dilute the purity of the magnetic substances, thereby affecting the magnetic separation effect of the magnetic minerals.

[0005] Second, the separation process of magnetic minerals is complicated. Specifically, magnetic minerals can be divided into different grades according to their magnetic strength, such as strong, medium and weak. Different grades of minerals have different values and uses in subsequent processing and utilization. Therefore, after preliminary magnetic separation, the magnetic minerals need to be accurately graded. In the actual beneficiation process, the magnetic minerals are first subjected to rough screening by the wet magnetic separator to remove most of the non-magnetic impurities. Then, these rough screened magnetic minerals need to be transferred to a dedicated separator for fine grading. This connection process involves multiple links of collection, transfer and supporting control operations, which lengthens the overall process from rough screening to grading of magnetic minerals, thereby making the separation process of magnetic minerals complicated.

[0006] In summary, the existing technology has obvious disadvantages and defects in actual use, so it needs to be improved. SUMMARY

[0007] To solve the problems in the prior art, the present application provides a wet magnetic separator that can effectively remove non-magnetic minerals mixed in the magnetic minerals during the magnetic separation process of the magnetic minerals in the liquid medium, significantly solving the problem of non-magnetic mineral mixing, thereby greatly improving the overall purity of the magnetic minerals.

[0020] Compared with the prior art, the present application has the following beneficial effects:

[0021] 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.

[0022] 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 9When the lower part of the discharge groove is opened, the upper magnet is separated from the partition plate and the adsorption of the magnetic material is released, at the same time, the external water source is discharged through the water outlet hole and the surface of the partition plate is washed, the magnetic material is discharged through the discharge groove to the outside for collection, the above discharge operation is repeated and the distance between the upper magnet and the magnetic material in the material collecting groove is controlled to realize the separation of magnetic materials with different magnetic strengths, in the process of completing the magnetic separation and discharging the magnetic minerals, the wet-type magnetic separator can realize the fine separation of the magnetic minerals, integrates the traditional multi-stage process into one step, greatly simplifies the separation process and significantly improves the separation efficiency;

[0023] 3. In the process of cleaning the non-magnetic material mixed in the magnetic material in the upper material collecting groove, the top end of the material box penetrates through the insertion groove and is inserted into the material collecting groove below the inner drum, and the above-mentioned adsorption operation of the magnetic material in the liquid medium is repeated to complete the adsorption of the next batch of magnetic material;

[0024] 4. In the process of adsorbing the magnetic material in the material box, the stirring blade can stir the liquid medium in the material box, so that the magnetic material in the liquid medium can be better adsorbed. BRIEF DESCRIPTION OF DRAWINGS

[0046] The top of the material box 2 and the bottom of the fixed box 6 are in an arc shape, the upper magnet 23, the lower magnet 37 and the partition plate 22 are in an arc shape.

[0047] The working principle of the device is as follows:

[0048] The lifting telescopic cylinder 16 drives the material box 2 to move upwards, the top end of the material box 2 penetrates through the slot 19 and is inserted into the material collecting groove 36 and abuts against the inner roller 31, at this time, the top opening of the material box 2 is closed by the inner roller 31, the liquid medium can be added or discharged into the material box 2 through the feeding 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 filled with the liquid medium, the first built-in telescopic cylinder 39 drives the lower lower magnet 37 to move downwards until the lower magnet 37 contacts the inner roller 31, the driving motor 15 drives the stirring blade 42 to rotate and agitates the liquid medium, under the adsorption of the lower magnet 37, the magnetic substances in the liquid medium are adsorbed into the lower material collecting groove 36, after a certain amount of magnetic substances are accumulated in the material collecting groove 36, the discharge valve 17 discharges part of the liquid medium to lower the liquid level in the material box 2, the material box 2 is reset and withdrawn from the outer roller 3, the second servo motor 11 drives the inner roller 31 to rotate by 180°, the material collecting grooves 36 on the upper side and the lower side are exchanged, the lower lower magnet 37 on the upper side moves downwards to release the adsorption of the magnetic substances in the material collecting groove 36, and the control telescopic cylinder 26 drives the partition plate 22 to move downwards to the lowest position (such as Figure 6As 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.

[0049] 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.

[0050] In the process of cleaning the non-magnetic materials mixed in the magnetic materials in the upper collecting tank 36, the hopper 2 is inserted into the collecting tank 36 below the inner drum 31 through the insertion slot 19, and the above-mentioned adsorption operation of the magnetic materials in the liquid medium is repeated to complete the adsorption of the next batch of magnetic materials.

[0051] In the process of adsorbing the magnetic materials in the hopper 2, the stirring blade 42 can stir the liquid medium in the hopper 2, so that the magnetic materials in the liquid medium can be better adsorbed.

[0052] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the description of the present application.
