Description

Technical Field

[0001] This utility model relates to the field of flotation technology, specifically to a mineralization cell and flotation equipment. Background Technology

[0002] Flotation is a widely used mineral processing method. In flotation equipment, the slurry is fed into a mechanically agitated chamber within the tank, where it is mechanically stirred and air is supplied. Target particles in the slurry selectively adhere to the air bubbles, forming mineralized bubbles to achieve mineralization. These mineralized bubbles rise to the surface, while other particles not attached to the bubbles are discharged from the bottom of the tank with the slurry, thus achieving mineral separation. However, the mechanically agitated chamber structure in related technologies suffers from unreasonable design, resulting in poor mineralization and low flotation efficiency. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, this utility model proposes a mineralization tank with improved mineralization effect.

[0005] This utility model embodiment also proposes a flotation device.

[0006] The mineralization tank of this utility model embodiment has a mechanical stirring chamber. The bottom of the mineralization tank is provided with an inlet for supplying slurry into the mechanical stirring chamber, and the top of the mineralization tank is provided with an outlet for discharging the slurry after mechanical stirring and mineralization. The mechanical stirring chamber is spherical or ellipsoidal.

[0007] According to an embodiment of the present invention, in a mineralization tank, slurry is introduced into the tank from bottom to top through an inlet. The slurry is mechanically agitated in a mechanical stirring chamber, forming mineralization bubbles, which are then discharged from the tank through an outlet. Because the mechanical stirring chamber is spherically or ellipsoidally shaped, the slurry and bubbles can tumble and surge multiple times along the inner wall of the tank, enhancing the turbulence effect and reducing weak mineralization zones within the mechanical stirring chamber. Therefore, the mineralization tank of this embodiment can enhance the mineralization effect.

[0008] In some embodiments, the mechanical stirring chamber is spherical, and the slurry outlet is located above the center of the sphere in the mechanical stirring chamber.

[0009] In some embodiments, the mechanical stirring chamber is ellipsoidal, the minor axis of the mechanical stirring chamber extends along the vertical direction of the mineralization tank, the major axis of the mechanical stirring chamber extends along the horizontal direction of the mineralization tank, and the slurry outlet is located above the major axis of the mechanical stirring chamber.

[0010] In some embodiments, the mechanical stirring chamber is spherical, and the slurry outlet is located below the center of the sphere in the mechanical stirring chamber.

[0011] In some embodiments, the mechanical stirring chamber is ellipsoidal, the minor axis of the mechanical stirring chamber extends along the vertical direction of the mineralization tank, the major axis of the mechanical stirring chamber extends along the horizontal direction of the mineralization tank, and the slurry outlet is located below the major axis of the mechanical stirring chamber.

[0012] In some embodiments, the mechanical stirring chamber is provided with a plurality of turbulence-enhancing plates, which are arranged at intervals along the circumference of the mechanical stirring chamber and are in contact with the inner wall of the mechanical stirring chamber.

[0013] The flotation equipment of this utility model includes a mineralization tank, which is the mineralization tank described in any one of the embodiments of this utility model; a tank body, wherein the mineralization tank is disposed in the tank body; a rotor assembly, wherein the rotor assembly includes a rotating shaft and a rotor, the lower end of the rotating shaft extends into the mechanical stirring chamber, the rotor is located in the mechanical stirring chamber, the rotor is installed at the lower end of the rotating shaft and is driven to rotate by the rotating shaft to stir the slurry in the mechanical stirring chamber; and a driving device, wherein the driving device is disposed above the tank body and connected to the rotating shaft to drive the rotating shaft to rotate.

[0014] The flotation equipment of this invention introduces slurry into the mineralization tank from bottom to top through the inlet. The slurry generates mineralization bubbles under the mechanical stirring action of the rotor, and these bubbles are discharged through the outlet. Because the mechanical stirring chamber is spherically or ellipsoidally shaped, the slurry can be repeatedly turbulent and agitated along the inner wall of the mineralization tank, enhancing the turbulence effect and reducing weak mineralization zones within the stirring chamber. Therefore, the flotation equipment of this invention can enhance the mineralization effect.

[0015] In some embodiments, the tank body has a lower region, an upper region, and a connecting region. The lower region is located below the mineralization tank, the upper region is located above the mineralization tank, and the connecting region is located between the outer peripheral wall of the mineralization tank and the inner peripheral wall of the tank body. Mineralization bubbles in the slurry discharged from the mechanical stirring chamber enter the upper region, and slurry containing other particles enters the lower region through the connecting region and is discharged from the lower region.

[0016] In some embodiments, the flotation equipment further includes an aeration device. The tank has an upper region and a column separation region. The upper region is located above the mineralization tank. The column separation region includes a lower region and a connecting region. The lower region is located below the mineralization tank. The connecting region is located between the outer peripheral wall of the mineralization tank and the inner peripheral wall of the tank. The aeration device is connected to the lower region and is used to aerate the lower region to perform column separation on the slurry entering the column separation region from the mechanical stirring chamber.

[0017] In some embodiments, the rotor includes a disk and a plurality of blades. The disk is mounted on the lower end of the rotating shaft.

[0031] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] The following is a reference appendix. Figures 1 to 7 This invention describes a mineralization cell 1 and a flotation device having the mineralization cell 1, according to embodiments of the present invention.

[0033] like Figures 1 to 4 As shown, the mineralization tank 1 of this utility model embodiment has a mechanical stirring chamber 13. The bottom of the mineralization tank 1 is provided with an inlet 11 for supplying slurry into the mechanical stirring chamber 13, and the top of the mineralization tank 1 is provided with an outlet 12 for discharging the slurry after mechanical stirring and mineralization. The mechanical stirring chamber 13 is spherical or ellipsoidal.

[0034] According to the mineralization tank 1 of this utility model embodiment, slurry is introduced into the mineralization tank 1 from bottom to top through the slurry inlet 11. The slurry can be mechanically stirred in the mechanical stirring chamber 13 to form mineralization bubbles, which can be discharged from the slurry outlet 12. Since the mechanical stirring chamber 13 is spherically or ellipsoidally shaped, the slurry can be repeatedly turbulent and agitated along the inner wall of the mineralization tank 1, thereby enhancing the turbulence effect of the slurry and reducing weak mineralization zones within the mechanical stirring chamber 13. Therefore, the mineralization tank 1 of this utility model embodiment can enhance the mineralization effect. It is understood that mineralization air is supplied to the mechanical stirring chamber during the mineralization process to form bubbles.

[0035] It is understandable that, such as Figure 2 As shown, the "spherical notch" refers to cutting off a portion of the upper part of a sphere, forming a slurry outlet 12 at the upper end. Within the longitudinal section of the spherical notch mechanical stirring chamber 13, the outline of the mechanical stirring chamber 13 is a perfectly circular outline with its upper end flush. For example... Figure 4 As shown, "ellipsoidal defect" means that a part of the upper part of the ellipsoid is cut off, and the upper end forms the slurry outlet 12.

[0036] Preferably, such as Figure 3 As shown, the mechanical stirring chamber 13 is spherical, and the slurry outlet 12 is located above the center O1 of the sphere in the mechanical stirring chamber 13. In this embodiment of the present invention, the mineralization tank 1, by configuring the mechanical stirring chamber 13 as described above, forms a relatively enclosed, confined space. This allows a portion of the upward-flowing slurry to be repeatedly mechanically stirred within the mechanical stirring chamber 13, thereby extending the time for reflection, rectification, and turbulence of the slurry within the mechanical stirring chamber 13. This increases the contact time, contact frequency, and impact frequency between bubbles and target particles, thereby improving the mineralization and flotation effects.

[0037] Preferably, such as Figure 4 As shown, the mechanical stirring chamber 13 is ellipsoidal in shape. The minor axis L2 of the mechanical stirring chamber 13 extends along the vertical direction of the mineralization tank 1, and the major axis L1 of the mechanical stirring chamber 13 extends along the horizontal direction of the mineralization tank 1. The slurry outlet 12 is located above the major axis of the mechanical stirring chamber 13. By setting the mechanical stirring chamber 13 to the above structure in the mineralization tank 1 of this embodiment, the mechanical stirring chamber is formed into a relatively closed confined space, so that a portion of the upward-flowing slurry can be deflected back into the mechanical stirring chamber 13 and repeatedly mechanically stirred. This prolongs the time for the slurry to reflect, rectify, and churn within the mechanical stirring chamber 13, thereby increasing the contact time, number of contacts, and number of impacts between bubbles and target particles, thus improving the mineralization and flotation effects.

[0038] In other examples, the mechanical stirring chamber 13 is spherical, and the slurry outlet 12 is located below the center O1 of the sphere in the mechanical stirring chamber 13. By configuring the mechanical stirring chamber 13 with the above-described structure, the mineralization tank 1 of this embodiment of the present invention is advantageous in reducing the probability of other particles (non-target mineral particles and / or tailings particles) depositing in the mechanical stirring chamber 13, and is also convenient for the processing and manufacturing of the mineralization tank 1, which is beneficial for improving the large-scale design of the mineralization tank 1.

[0039] In other examples, the mechanical stirring chamber 13 is ellipsoidal, with its minor axis extending vertically along the mineralization tank 1 and its major axis extending horizontally along the mineralization tank 1. The slurry outlet 12 is located below the major axis of the mechanical stirring chamber 13. By configuring the mechanical stirring chamber 13 in the above-described structure, the mineralization tank 1 of this embodiment of the present invention helps to reduce the probability of other particles (non-target mineral particles and / or tailings particles) depositing in the mechanical stirring chamber 13, and facilitates the processing and manufacturing of the mineralization tank 1, thereby improving the large-scale design of the mineralization tank 1.

[0040] In some embodiments, such as Figure 2As shown, the mechanical stirring chamber 13 is equipped with multiple turbulence-enhancing plates 14, which are arranged at intervals along the circumference of the mechanical stirring chamber 13 and are in contact with the inner wall of the mechanical stirring chamber 13. It can be understood that a rotor 22 for stirring the slurry is installed inside the mechanical stirring chamber 13, and the multiple turbulence-enhancing plates 14 are arranged around the rotor 22. When the rotor 22 rotates, due to the circumferential arrangement of the multiple turbulence-enhancing plates 14, the slurry flowing circumferentially within the mechanical stirring chamber 13 is stopped and collided with by the multiple turbulence-enhancing plates 14, thereby improving the turbulence effect of the slurry within the mechanical stirring chamber 13 and thus improving the mineralization effect.

[0041] Optionally, such as Figure 3 and Figure 4 As shown, a cover plate 31 is provided on the upper side of the mineralization tank 1. The cover plate 31 is located above the slurry outlet 12 and has a gap between it and the top surface of the mineralization tank 1. Alternatively, the cover plate 31 is installed on the top surface of the mineralization tank 1 to cover the slurry outlet 12, and the cover plate 31 has a cover plate through hole 311. The cover plate 31 and the mineralization tank 1 define a relatively enclosed mineralization area including the mechanical stirring chamber 13. The gap and / or the cover plate through hole 311 constitute a slurry outlet channel for discharging slurry from the mechanical stirring chamber 13. This prolongs the time for the slurry to reflect, rectify, and churn within the mechanical stirring chamber 13, thereby increasing the contact time, contact, and impact frequency between bubbles and target particles, thus improving the mineralization and flotation effect, and consequently increasing the mineralization and flotation efficiency of the mineralization tank 1.

[0042] like Figure 1 As shown, the flotation equipment of this utility model includes: a mineralization tank 1, a tank body 4, a rotor assembly 2, and a drive device (not shown). The mineralization tank 1 is the mineralization tank 1 of this utility model. The mineralization tank 1 is disposed inside the tank body 4. The rotor assembly 2 includes a rotating shaft 21 and a rotor 22. The lower end of the rotating shaft 21 extends into the mechanical stirring chamber 13. The rotor 22 is located inside the mechanical stirring chamber 13. The rotor 22 is installed at the lower end of the rotating shaft 21 and is driven to rotate by the rotating shaft 21 to stir the slurry in the mechanical stirring chamber 13. The drive device is disposed above the tank body 4 and connected to the rotating shaft 21 to drive the rotating shaft 21 to rotate.

[0043] The flotation equipment of this embodiment of the invention introduces slurry into the mineralization tank 1 from bottom to top through the slurry inlet 11. The slurry generates mineralization bubbles under the mechanical stirring action of the rotor 22, and these bubbles are discharged through the slurry outlet 12. Because the mechanical stirring chamber 13 is spherically or ellipsoidally shaped, the slurry can be repeatedly turbulent and agitated along the inner wall of the mineralization tank 1, enhancing the turbulence effect and reducing weak mineralization zones within the mechanical stirring chamber 13. Therefore, the flotation equipment of this embodiment of the invention can enhance the mineralization effect.

[0044] Specifically, the drive unit (not shown) can be a combination of a drive motor and a pulley assembly, i.e., the drive motor drives the pulley assembly to rotate, and the pulley assembly drives the rotating shaft 21 to rotate synchronously.

[0045] like Figure 1 As shown, the bottom of the tank 4 can be any shape such as conical (funnel-shaped), pyramidal, or wedge-shaped to guide the tailings and thus improve the efficiency of tailings being discharged from the discharge port 43.

[0046] In some embodiments, such as Figure 1 and Figure 7 As shown, the rotating shaft 21 is provided with a gas supply channel 211 for supplying gas to the mechanical stirring chamber 13. It can be understood that the gas in the mechanical stirring chamber 13 can be supplied through the gas supply channel 211 in the rotating shaft 21. Thus, the rotating shaft 21 can both drive the rotor 22 to rotate and provide mineralizing gas to the mechanical stirring chamber 13. Moreover, the structure is compact and the number of parts used is reduced.

[0047] In other examples, mineralizing gas can also be introduced into the mechanical stirring chamber 13 through a pipeline at the slurry inlet 11 of the mineralizing tank 1, or the gas can be introduced into the mechanical stirring chamber 13 by self-priming through the feed pipe 32.

[0048] In some embodiments, such as Figure 1 As shown, the tank 4 has a lower region 411, an upper region 42, and a connecting region 412. The lower region 411 is located below the mineralization tank 1, the upper region 42 is located above the mineralization tank 1, and the connecting region 412 is located between the outer peripheral wall of the mineralization tank 1 and the inner peripheral wall of the tank 4. Mineralization bubbles in the slurry discharged from the mechanical stirring chamber 13 enter the upper region 42, and the slurry containing other particles enters the lower region 411 through the connecting region 412 and is discharged from the lower region 411.

[0049] It is understood that the flotation equipment of this utility model embodiment can be used as a flotation equipment for mechanical stirring mineralization. When the flotation equipment is working, the mineralized bubbles in the slurry discharged from the mechanical stirring chamber 13 enter the upper region 42, and the slurry containing other particles (i.e., tailings) directly enters the lower region 411 through the connecting region 412 and is discharged from the discharge port 43 at the bottom of the tank 4.

[0050] In some embodiments, such as Figure 1As shown, the flotation equipment also includes an aeration device 5. The tank 4 has an upper region 42 and a column separation region 41. The upper region 42 is located above the mineralization tank 1. The column separation region 41 includes a lower region 411 and a connecting region 412. The lower region 411 is located below the mineralization tank 1. The connecting region 412 is located between the outer peripheral wall of the mineralization tank 1 and the inner peripheral wall of the tank 4. The aeration device 5 is connected to the lower region 411 and is used to aerate the lower region 411 to perform column separation on the slurry entering the column separation region 41 from the mechanical stirring chamber 13.

[0051] In this flotation device, mineralized bubbles flow out from the outlet 12 of the mineralization tank 1 and rise to the upper region 42. Other particles not attached to the bubbles can flow out from the outlet 12 of the mineralization tank 1 and, under the action of gravity, enter the lower region 411 through the connecting region 412. Under the action of the aeration device 5, column separation can be carried out in the lower region 411. After column separation, the mineralized bubbles flow upward to the upper region 42 through the connecting region 412. The tailings fall to the bottom of the tank 4 under the action of gravity and are discharged from the discharge port 43. It can be understood that the flotation equipment of this embodiment uses mechanical stirring combined with column separation to mineralize the bubbles, so as to improve the mineralization and flotation effect of the flotation equipment.

[0052] In some embodiments, such as Figure 7 As shown, the rotor 22 includes a disk 222 and multiple blades 223. The disk 222 is mounted on the lower end of the rotating shaft 21. The multiple blades 223 are spaced apart along the circumference of the disk 222 on its outer periphery. In the longitudinal section of the rotor 22, the outline of the outer surface of the blades 223 includes a vertical section 2234 and an arc-shaped section 2235. The upper end of the arc-shaped section 2235 is connected to the lower section of the vertical section 2234 and gradually extends inward. Thus, when the rotor 22 rotates, the stirred slurry area flips upward along the arc-shaped section 2235. By setting the blades 223 to the above structure, the flotation equipment of this embodiment can improve the turbulence effect of the slurry in the mechanical stirring chamber 13, enhance the capture effect of bubbles on target particles, enhance the intensity of internal slurry circulation, and improve the energy utilization rate of the impeller rotation.

[0053] Optionally, such as Figure 7 As shown, the blade 223 has a perforated hole 2233 extending along its thickness direction. By designing the blade 223 of the flotation device in this embodiment of the invention as a perforated structure, it is easier to generate microbubbles when the impeller rotates, resulting in better mixing of the slurry and bubbles, which is more conducive to the mineralization of fine-grained minerals.

[0054] For example, the perforated hole 2233 can be a strip hole or a round hole. The strip hole can extend obliquely, horizontally, or vertically. There can be multiple perforated holes 2233, which are arranged discretely.

[0055] Optionally, such as Figure 7 As shown, the rotor 22 is provided with an air supply channel 211 for supplying gas to the mechanical stirring chamber 13, the wheel 222 is provided with an air jet channel 2220, and the outer circumferential surface of the wheel 222 is provided with an air jet hole. The air jet channel 2220 is connected to the air supply channel 211 and the air jet hole, so that the mineralizing gas diffuses to the periphery of the mechanical stirring chamber 13, thereby improving the mixing degree of the slurry and the air bubbles and improving the mineralization effect of the flotation equipment.

[0056] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the rotor 22 is in the form of an impeller. The impeller includes a hub 221, a disk 222, a top plate 224, a bottom plate 225, and blades 223. The blades 223 include upper blades 2231 and lower blades 2232. The hub 221 is mounted on the lower end of the rotating shaft 21. The disk 222, top plate 224, and bottom plate 225 are mounted on the hub 221, with the disk 222 located between the top plate 224 and the bottom plate 225. There are multiple upper blades 2231 and multiple lower blades 2232. Multiple upper blades 2231 are located between the upper surface of the disk 222 and the top plate 224 and are arranged at intervals along the circumference of the disk 222. Multiple lower blades 2232 are located between the lower surface of the disk 222 and the disk 222 and are arranged at intervals along the circumference of the disk 222. The upper blades 2231 and lower blades 2232 are either one-to-one corresponding or staggered along the circumference of the disk 222. Preferably, the upper blade 2231 and the lower blade 2232 are staggered, that is, the upper blade 2231 and the lower blade 2232 are not aligned with each other along the axial direction of the impeller.

[0057] When the impeller rotates, the upper blade 2231 on the upper side of the impeller 222 and the lower blade 2232 on the lower side of the impeller 222 rotate simultaneously. On the one hand, this can enhance the impeller's suction capacity (the ability to draw slurry from the inlet 11 into the mechanical stirring chamber 13). On the other hand, it can enhance the intensity of internal slurry circulation, improve the mineralization effect, and enhance the selectivity in the flotation process.

[0058] For example, the upper blade 2231 and the lower blade 2232 are arranged radially, with the number of both upper blade 2231 and lower blade 2232 ranging from 4 to 16, and are evenly distributed. It should be noted that the number of upper blade 2231 and lower blade 2232 may be equal or unequal, and this embodiment of the present invention does not limit this.

[0059] Since the upper blade 2231 is located between the upper surface of the impeller 222 and the top plate 224, and the lower blade 2232 is located between the lower surface of the impeller 222 and the impeller 222, the intensity of the internal slurry circulation can be further enhanced, the energy utilization rate of the impeller rotation can be improved, and the effect of bubbles capturing target particles can be enhanced, thereby enhancing the selectivity in the flotation process.

[0060] For example, the outer periphery of the top plate 224 is substantially the same in size as the outer periphery formed by the plurality of upper blades 2231. The outer periphery of the bottom plate 225 is substantially the same in size as the outer periphery formed by the plurality of lower blades 2232.
