Description

Technical Field

[0001] This invention belongs to the technical field of gold ore refining, and more specifically, relates to an ultra-large intelligent leaching adsorption tank. Background Technology

[0002] As the core equipment in the whole-mud cyanidation carbon-in-pulp gold beneficiation process, the performance of the leaching adsorption tank directly affects the metal recovery rate, energy consumption level and production economy. In recent years, with the expansion of mineral resource development and the improvement of mineral processing capacity, the large-scale leaching adsorption tank has become an industry development trend.

[0003] Existing technologies, such as patent document CN119971878A, describe a large double-impeller leaching mixing tank, relating to the field of gold ore leaching mixing tank technology. The tank includes a transmission unit, a bridge unit, a mixing unit, and a tank body. The transmission unit includes a motor, a high-speed coupling, a reducer, a low-speed coupling, a frame, and bearing supports. The bearing supports include a main shaft, a bearing housing, a thrust bearing, an upper self-aligning roller bearing, an upper pressure cap, a lower self-aligning roller bearing, a lower pressure cap, and a half-coupling. The mixing unit includes an upper shaft, a lower shaft, an upper hub, a lower hub, and blades. A shaft end fixing device is provided at the center of the bottom of the tank body. An air-filling device is provided at the bottom of the tank body. This invention patent is used for gold ore slurry leaching operations. It has a large processing capacity, stable ore flow, and uniform slurry mixing. Air is introduced into the slurry through a special aeration device, resulting in a large aeration volume. The structure is simple, and the air is evenly dispersed by the blade agitation, which can effectively improve the leaching rate. However, the existing large double-impeller leaching mixing tank technology still has the following defects: 1. In the existing technology, since only the existing equipment uses traditional single stirring shaft stirring, the stirring range is limited, which makes it easy for the ultra-large tank to have stirring dead corners, making it difficult to mix the slurry evenly, and the material does not have sufficient contact with the leaching agent and adsorbent. At the same time, the single-shaft stirring mode is difficult to flexibly adapt to different stages of the slurry, such as strong mixing in the early stage of leaching and gentle contact in the later stage of adsorption, resulting in low leaching and adsorption efficiency and high equipment operation and maintenance costs. 2. In the existing technology, since the slurry often contains mineral particles of varying hardness, these particles will continuously scour the surface of the impeller during the stirring process, causing the impeller to wear easily, resulting in a decrease in stirring efficiency. The slurry cannot be fully and uniformly mixed, which in turn affects the leaching and adsorption effect and reduces the extraction rate of useful components.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an ultra-large intelligent leaching adsorption tank in order to achieve a more practical purpose. Summary of the Invention

[0011] A further technical solution: The protective sleeve is fixed to the bottom end of the cable tray by bolts, and the bottom end of the protective sleeve has a slot that matches the moving trajectory of the driven shaft.

[0012] A further technical solution: A ball bearing is installed between the connecting frame and the rotating sleeve, and the connecting frame forms a rotating structure with the rotating sleeve through the ball bearing.

This realizes the reciprocating stirring function of the device, which allows the slurry to form a more complex flow field in the tank, improves the contact efficiency between the slurry and the reagent and gold-loaded carbon, and avoids slurry stratification caused by unidirectional stirring, thereby improving the leaching and adsorption effect to a certain extent. The present invention discloses an ultra-large intelligent leaching adsorption tank, which uses a microporous gas distributor to efficiently disperse gas into the slurry through stirring negative pressure. At the same time, the swept-back variable cross-section airfoil structure and the gradually changing inclination angle and width of the blades generate strong axial flow to drive the slurry circulation. This realizes the uniform mixing and mass transfer function of the gas-liquid-solid three phases of the device, which to a certain extent ensures that the slurry, reagents and gold-loaded carbon are in full contact, thereby improving the leaching adsorption efficiency.

[0022] As attached Figure 1 To be continued Figure 7 As shown: This invention provides an ultra-large intelligent leaching adsorption tank, including a tank body 1, Slurry discharge port 2 is located on one side of the bottom end of tank 1 and is used for slurry discharge and system maintenance; The cable tray 3 is fixed to the top of the trough 1, and the top of the cable tray 3 is covered and fixed with a partition frame 4. The reducer 6 is fixed to the top of the partition frame 4, and a drive motor 5 is installed on one side of the top of the reducer 6, with the output shaft end connected to the input shaft end of the reducer 6. The main shaft 12 is fixed to the output shaft end of the reducer 6, and the bottom end of the main shaft 12 is rotatably connected to the support seat 13 connected to the groove 1. The connecting sleeve 14 is fixed on the outside of the main shaft 12. A microporous gas distributor 15 is welded and fixed on the outer wall of the connecting sleeve 14. A blade 8 is fixed on one side of the microporous gas distributor 15. Sensor assembly 11 is installed on one side inside the tank 1; The multi-stage stirring structure 7 is located on the outside of the main shaft 12 and is used to stir the dead-angle area in the tank 1. The oscillating structure 9 is located at the bottom of the partition frame 4 and is used to expand the mixing range of the multi-stage mixing structure 7.

[0023] In this embodiment, when the drive motor 5 starts, its output shaft drives the reducer 6 to run, so that the reducer 6 drives the main shaft 12 to rotate through the output shaft. At the same time, the main shaft 12 rotates stably under the support of the support seat 13, and drives the blade 8 to rotate through the connecting sleeve 14, pushing the slurry to circulate up and down. The baffle 10 changes the flow direction of the slurry to enhance the turbulence and prevent the slurry from swirling. When it is necessary to discharge the slurry or perform maintenance, the discharge port 2 is opened, and the slurry is discharged from there. The cable tray 3 and the partition frame 4 provide a safe operating space for equipment inspection and maintenance.

[0024] Preferably, the multi-stage stirring structure 7 includes a rotating sleeve 707 sleeved on the outer side of the top of the main shaft 12 and connected to the partition frame 4. The bottom of the outer side of the rotating sleeve 707 is rotatably connected to a connecting frame 706. The inner sides of both ends of the connecting frame 706 are rotatably connected to a driven shaft 703. A stirring blade 702 is fixed on the outer side wall of the driven shaft 703. A first driven transmission pulley 705 is fixed on the top of the outer side of the driven shaft 703. A first transmission pulley 708 is fixed on the outer side of the main shaft 12. A first belt 704 is sleeved on the outer side of the first driven transmission pulley 705 and contacts the first transmission pulley 708. A protective sleeve 701 connected to the bridge frame 3 is sleeved on the outer side of the connecting frame 706.

[0025] In this embodiment, the main shaft 12 drives the driven shaft 703 to rotate via the first transmission pulley 708, the first belt 704 and the first driven transmission pulley 705, so that the stirring blades 702 stir the area near the edge of the tank 1, thereby eliminating the stirring dead zone to a certain extent.

[0026] Preferably, the swing structure 9 includes a bearing seat 904 fixed to one side of the bottom end of the partition frame 4. A rotating shaft 903 is rotatably connected inside the bearing seat 904. A crank 902 is fixed to the bottom end of the rotating shaft 903. A swing arm 901 is rotatably connected to one side of the bottom end of the crank 902. A slide rod 908 is rotatably connected to the side of the bottom end of the swing arm 901 away from the crank 902. A moving groove 909 is provided on one side inside the connecting frame 706. A second driven transmission pulley 905 is fixed to the outside of the rotating shaft 903. A second transmission pulley 907 is fixed to the outside of the top end of the main shaft 12. A second belt 906 that contacts the second driven transmission pulley 905 is sleeved on the outside of the second transmission pulley 907.

[0027] In this embodiment, the main shaft 12 drives the rotating shaft 903 to rotate, causing the crank 902 to pull the connecting frame 706 to swing left and right through the swing arm 901 and the slide rod 908. At the same time, the driven shaft 703 swings accordingly, which to a certain extent widens the stirring range of the stirring blade 702 and further improves the uniformity of the slurry mixing.

[0028] Preferably, the blade 8 has a swept-back variable cross-section airfoil structure, and the inclination angle and width of the blade 8 gradually change radially. The surface of the blade 8 is coated with a highly wear-resistant tungsten carbide coating.

[0029] In this embodiment, the swept-back variable cross-section airfoil structure and the radially gradual design of the inclination angle and width can adapt to the flow field requirements of different areas in the tank, enhance the axial circulation capability and reduce turbulent shear force, and reduce the wear of particles on the blade 8 to a certain extent. The high wear-resistant tungsten carbide coating can improve the wear resistance of the blade 8 in the high-concentration slurry environment and extend its service life.

[0030] Preferably, there are two sets of driven shafts 703, which are symmetrically distributed on the axis of the main shaft 12.

[0031] In this embodiment, two sets of driven shafts 703 are symmetrically distributed on the axis of the main shaft 12, which can synchronously stir the two sides of the tank 1, complementing the stirring effect of the main shaft 12, reducing the uneven flow field caused by unilateral stirring, eliminating stirring dead corners to a certain extent, and improving the overall mixing effect of the slurry.

[0032] Preferably, the protective sleeve 701 is fixed to the bottom end of the cable tray 3 by bolts, and the bottom end of the protective sleeve 701 is provided with a slot that matches the moving trajectory of the driven shaft 703.

[0033] In this embodiment, the slot of the protective sleeve 701 is adapted to the movement trajectory of the driven shaft 703, which can both prevent slurry from entering the transmission component and provide space for the driven shaft 703 to move.

[0034] Preferably, a ball bearing is installed between the connecting frame 706 and the rotating sleeve 707, and the connecting frame 706 and the rotating sleeve 707 form a rotating structure through the ball bearing.

[0035] In this embodiment, the ball bearing between the connecting frame 706 and the rotating sleeve 707 forms a rotating structure, reducing frictional resistance during relative motion, allowing the connecting frame 706 to swing more smoothly, and reducing energy loss to a certain extent.

[0036] Preferably, the diameter of the second driven transmission pulley 905 is larger than the diameter of the second transmission pulley 907, and the second belt 906 is sleeved on the outside of the rotating sleeve 707 and contacts the second driven transmission pulley 905.

[0037] In this embodiment, the diameter of the second driven transmission pulley 905 is larger than that of the second transmission pulley 907. When driven by the second belt 906, the rotation speed of the rotating shaft 903 can be reduced. In conjunction with the transmission on the outside of the rotating sleeve 707, the oscillating structure 9 runs more smoothly and to a certain extent avoids the stirring blade 702 from oscillating too fast.

[0038] Preferably, the internal width of the movable groove 909 matches the diameter of the slide bar 908, and the slide bar 908 and the movable groove 909 form a sliding structure.

[0039] In this embodiment, the internal width of the moving groove 909 matches the diameter of the slide bar 908, which can prevent the slide bar 908 from swaying radially when moving. By sliding the slide bar 908 in the moving groove 909, the swing of the swing arm 901 can be converted into the swing power of the connecting frame 706, so that the stirring range of the driven shaft 703 expands according to the preset trajectory, which improves the uniformity of slurry mixing to a certain extent, while reducing wear between structures.

[0040] Preferably, baffles 10 are fixed on the inner sidewall of the tank 1, and the baffles 10 are arranged in a ring at equal intervals on the inner sidewall of the tank 1.

[0041] In this embodiment, the baffles 10 on the inner wall of the tank 1 are arranged in a ring at equal intervals, which can change the direction of the slurry rotation, enhance the degree of turbulence, prevent the slurry from forming eddies by rotating synchronously with the main shaft 12, and improve the contact efficiency between the slurry and the reagent.

[0042] The specific method of using this invention is as follows: The slurry, mixed minerals, reagents, and gold-loaded carbon are introduced into the tank 1. When the drive motor 5 starts, its output shaft drives the reducer 6, causing the reducer 6 to drive the main shaft 12 to rotate via its output shaft. Simultaneously, the main shaft 12 rotates stably under the support of the support base 13, driving the connecting sleeve 14 to rotate. Then, the microporous gas distributor 15 on the outside of the connecting sleeve 14 rotates with it, utilizing the negative pressure effect generated by stirring to efficiently disperse the gas into the slurry. At the same time, the impeller 8 on the outside of the connecting sleeve 14 also rotates accordingly. Rotation: Due to the swept-back variable cross-section airfoil structure of blade 8 and the gradual change of inclination and width along the radial direction, it generates strong axial flow during rotation, which drives the slurry to circulate up and down. The high wear-resistant tungsten carbide coating on the surface of blade 8 reduces the wear of slurry particles to a certain extent. The baffle 10 changes the slurry flow direction to enhance the degree of turbulence and prevent the slurry from swirling. When it is necessary to discharge slurry or perform maintenance, the discharge port 2 is opened and the slurry is discharged from there. The cable tray 3 and the partition frame 4 provide a safe operating space for equipment inspection and maintenance. The sensor assembly 11 integrates a gamma-ray densitometer, an optical sensor, a corrosion-resistant electrode, and an online XRF analyzer. It is used to collect the temperature, concentration, turbidity, pH value, and metal ion content of the slurry in the tank 1 in real time. The collected data is preprocessed by the edge computing node and then uploaded to the data acquisition platform. The platform analyzes the data through an industrial Internet of Things architecture. When the slurry concentration or viscosity changes, the system starts an adaptive stirring strategy. By adjusting the output of the drive motor 5, the speed of the main shaft 12 is changed, which ensures the uniformity of slurry mixing and reduces energy consumption to a certain extent. During grouting and slurry discharge, the system controls the feed rate and the opening of the discharge valve in a closed loop based on the data from the flow meter and liquid level sensor. During grouting, the amount of dilution water added is adjusted according to the slurry concentration. During slurry discharge, the timing of discharge is optimized based on turbidity and metal ion data. At the same time, the system identifies potential faults such as impeller wear or motor overload through multi-dimensional health models such as torque-temperature correlation analysis, triggering graded protection measures to a certain extent and improving the reliability of equipment operation. When the main shaft 12 is running, the rotation of the main shaft 12 drives the first transmission pulley 708 to rotate. Then, the first transmission pulley 708 drives the first driven transmission pulley 705 to rotate through the first belt 704. This causes the first driven transmission pulley 705 to drive the driven shaft 703 to rotate. At the same time, the stirring blades 702 on the outside of the driven shaft 703 rotate with it, stirring the area near the edge of the tank 1. This eliminates the stirring dead zone to a certain extent. The protective sleeve 701 prevents the slurry from entering the transmission components and affecting the operation. When the oscillating structure 9 is running, the main shaft 12 drives the second transmission pulley 907 to rotate. Then, the second transmission pulley 907 drives the second driven transmission pulley 905 to rotate via the second belt 906. The second driven transmission pulley 905 drives the rotating shaft 903 to rotate within the bearing seat 904. The rotating shaft 903 drives the crank 902 to rotate. The crank 902 pulls the slide rod 908 through the swing arm 901 to slide within the moving groove 909 of the connecting frame 706. This causes the connecting frame 706 to oscillate left and right under the support of the rotating sleeve 707. At the same time, the driven shaft 703 oscillates with the connecting frame 706, which to a certain extent widens the stirring range of the stirring blade 702 and further improves the uniformity of the slurry mixing.

Many modifications and variations will be apparent to those skilled in the art.
