Description

Technical Field

[0001] This invention belongs to the technical field of mining mixing tanks, specifically relating to a mining mixing tank with multiple sets of agitators linked together. Background Technology

[0002] Mining mixing tanks are specialized equipment used in mineral processing to thoroughly mix slurry and reagents, suspending mineral particles. They are primarily used before flotation operations, but also in hydrometallurgy, leaching, extraction, and wastewater treatment. A motor drives a vertical shaft and impeller to rotate at high speed. The impeller generates axial thrust and negative pressure, drawing the slurry in from the center and throwing it radially out. Constrained by the guide tube and tank walls, the slurry forms a downward-centering, upward-flowing circulation, achieving uniform mixing of reagents and slurry. After mixing, the slurry is discharged from the overflow port.

[0003] Currently, traditional mining mixing tanks have a relatively simple structural design, with only a single independent agitator and no auxiliary disturbance structures to assist in operation. During normal operation, the rotation of the agitator impeller creates a negative pressure zone at the shaft center, continuously drawing in slurry from the center and then throwing it radially outwards to complete the mixing operation. This traditional flow field results in a simple flow field distribution, a small material disturbance range, poor uniformity of slurry concentration and reagent ratio in different areas of the tank, and a tendency for bottom accumulation and localized static zones. This reduces the overall efficiency of slurry mixing, conditioning, and reaction, making it unsuitable for handling large volumes of high-concentration slurry and complex mineral processing processes. Therefore, a mining mixing tank with multiple agitators working in tandem is needed to address these issues. Summary of the Invention

[0011] In order to create a forced circulation flow field inside the mixing drum, realize the switching between slurry lifting and mixing and reverse unloading, eliminate the dead corners of mixing at the edge of the tank, and improve the local mixing effect, preferably, the auxiliary mixing mechanism includes an auxiliary shaft, the upper end of the auxiliary shaft is fixedly connected to a driven helical gear, the lower end of the auxiliary shaft is fixedly installed with a stirring wheel, the stirring wheel is rotatably installed on the inner bottom of the mixing drum, and the outer surface of the stirring wheel is fixedly installed with helical blades.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By symmetrically setting four sets of mixing cylinders inside the mixing tank, and cooperating with the stirring rod and stirring blades of the central stirring mechanism and the folding blades, stirring wheel, and spiral blades of the auxiliary stirring mechanism, a full-area composite mixing flow field is formed; the bottom stirring blades forcefully push the slurry in the hopper upwards, and the material enters the mixing cylinder through the mixing port. The spiral blades carry out forced circulation mixing inside the cylinder, and then fall back to participate in secondary mixing in the middle of the tank; through the multi-layer convection circulation structure of bottom pushing, cylinder circulation and central turbulence, the defects of traditional single-axis stirring edge static zone, bottom accumulation, concentration stratification, and uneven reagent dispersion are solved, and the slurry conditioning and reagent reaction effect is improved; 2.

By installing a blower blade at the upper end of the central shaft and a defoaming rake blade at the upper end of the auxiliary shaft, the blower blade generates a directional airflow during the mixing operation, which evenly blows the foam gathered in the center of the tank to the surrounding liquid surface. This, combined with multiple sets of defoaming rake blades arranged in a ring, rotates at high speed to cut and break up the surface foam. Compared with natural defoaming and chemical defoaming, this structure requires no additional consumables and can eliminate the foam in real time and continuously, avoiding foam accumulation that occupies the effective volume of the tank and causes material loss due to the entrainment of fine mineral particles. At the same time, it stabilizes the liquid surface conditions, ensures uniform discharge concentration, and improves the stability of the mineral processing process. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please see Figures 1 to 7 The present invention provides a technical solution: a mining mixing tank with multiple sets of agitators linked together, including a mixing tank 1, a driving mechanism 2, a central mixing mechanism 3 and an auxiliary mixing mechanism 4; Four mixing cylinders 14 are fixedly installed inside the mixing tank 1, and a mixing port 16 is opened at the lower end of the mixing cylinder 14; a feeding hopper 12 is fixedly installed at the bottom of the mixing tank 1, and a top seat 15 is fixedly installed at the top; a drive mechanism 2 is fixedly installed on the top seat 15; a central mixing mechanism 3 is arranged in the middle of the mixing tank 1, with its lower end extending into the feeding hopper 12 and its upper end connected to the drive mechanism 2. The auxiliary stirring mechanism 4 is mounted inside the drive mechanism 2, and its upper end is also connected to the drive mechanism 2 for transmission. The stirring tank 1 is the main body for the overall stirring operation, providing a closed and stable slurry mixing space. The four mixing cylinders 14 are independent circulating mixing chambers, which, together with the lower mixing port 16, realize the inflow and outflow circulation of the slurry, enhancing the mixing efficiency of the liquid and the slurry. The hopper 12 is used to collect the bottom slurry, avoid material accumulation at the bottom of the tank, and facilitate centralized feeding and discharge. The top seat 15 provides stable installation support for the upper drive structure and auxiliary stirring structure. The drive mechanism 2 is the only power source of the whole machine, realizing single-power multi-group linkage transmission. The central mixing mechanism 3 is responsible for the main mixing and pushing circulation in the center and bottom feeding area of ​​the tank; the auxiliary mixing mechanism 4 works with the central structure to achieve full-area auxiliary mixing, defoaming, and secondary mixing, solving the problems of large dead angles and uneven mixing in traditional single-shaft mixing; when the equipment is working, the slurry and the preparation solution are put into the mixing tank 1, and the upper transmission and mixing structure is fixed by the top seat 15. The power is output through the drive mechanism 2, which drives the central mixing mechanism 3 and the four sets of auxiliary mixing mechanisms 4 to work together. The material forms a circulation mixing in the inner cavity of the mixing tank 1, the mixing cylinder 14 and the feeding hopper 12. After the mixing is completed, the material is discharged centrally by the bottom structure, completing the overall mixing operation.

[0019] As can be seen from the above description, the present invention has the following beneficial effects: Four sets of mixing cylinders 14 are symmetrically arranged inside the mixing tank 1, which, together with the stirring rod 33 and stirring blade 34 of the central stirring mechanism 3 and the folding blade 43, stirring wheel 44, and spiral blade 45 of the auxiliary stirring mechanism 4, form a full-area composite stirring flow field. The bottom stirring blade 34 forcibly pushes the slurry in the feed hopper 12 upward, and the material enters the mixing cylinder 14 through the mixing port 16. It is then subjected to forced circulation mixing by the spiral blade 45 and falls back to participate in secondary mixing in the middle of the tank. Through the multi-layer convection circulation structure of bottom pushing, internal circulation and central turbulence, the defects of traditional single-axis stirring, such as the static zone at the edge, bottom accumulation, concentration stratification, and uneven reagent dispersion, are solved, thereby improving the slurry conditioning and reagent reaction effect.

Figure 1-3 A mounting frame 11 is fixedly installed on the lower side of the mixing tank 1, and a discharge port 13 is assembled at the lower end of the hopper 12. The mounting frame 11 provides support and fixation for the entire mixing tank equipment, ensuring the overall stability of the equipment during operation and reducing vibration and displacement. The discharge port 13 serves as the final unloading channel for the equipment, used for the centralized discharge of homogenized slurry after mixing, realizing continuous feeding, mixing, and discharging operations. The equipment is stably supported by the mounting frame 11 throughout the process, offsetting the vibration generated by the mixing operation and ensuring stable operation of the equipment. After the slurry mixing and conditioning operations are completed, the homogenized slurry collected at the bottom is gathered by the hopper 12 and finally discharged from the discharge port 13, completing the unloading process.

Figure 1-7 The central mixing mechanism 3 includes a central shaft 31, the upper end of which is fixedly connected to the drive motor 21, and the lower end of which is rotatably mounted inside the hopper 12 via a star-shaped bracket. A stirring rod 33 is fixedly installed in the middle of the shaft of the central shaft 31. The central shaft 31 is the core transmission rod of the central mixing mechanism, transmitting the motor power to drive the overall central mixing structure. The star-shaped bracket provides limiting support for the lower end of the central shaft 31, ensuring the coaxiality and stability of the long shaft during high-speed rotation, and preventing shaft swaying and eccentric wear. The stirring rod 33 laterally disturbs and mixes the slurry and liquid in the middle of the tank, breaking up material agglomerates, eliminating the static mixing zone in the middle of the tank, and improving the uniformity of the middle layer mixing. During operation, the drive motor 21 drives the central shaft 31 to rotate at high speed, and the star-shaped bracket provides limiting support for the lower end of the shaft throughout the entire process, ensuring stable operation. The stirring rod 33 rotates synchronously with the central shaft 31, continuously disturbing and breaking up the surging slurry and liquid in the middle of the tank laterally. The mixing process eliminates the static mixing zone in the middle, ensuring uniform mixing of the middle layer of materials. A stirring plate 34 is fixedly installed at the bottom of the central shaft 31, located inside the hopper 12. A blower blade 32 is fixedly installed at the top of the central shaft 31. The bottom stirring plate 34 is specifically designed to forcibly agitate and push the slurry inside the hopper 12, preventing high-concentration slurry from settling and caking at the bottom of the hopper, while also providing power for the slurry to circulate and rise. The upper blower blade 32 rotates synchronously with the shaft to generate directional airflow, which can disperse the foam gathered in the center of the tank to the surrounding areas, and complete the defoaming of the entire area in conjunction with the defoaming structure, solving the problems of foam accumulation in the center and overflow. During the operation of the central shaft 31, the bottom stirring plate 34 continuously agitates the slurry inside the hopper 12, forcibly pushing the bottom material upwards for circulation, avoiding material accumulation and caking. At the same time, the upper blower blade 32 rotates synchronously to generate wind pressure, which evenly blows the foam accumulated in the center of the tank to the surrounding defoaming area, assisting in the completion of the entire defoaming operation.

[0022] Further reading is available. Figure 1-6The auxiliary stirring mechanism 4 includes an auxiliary shaft 41, the upper end of which is fixedly connected to the driven helical gear 26; a stirring wheel 44 is fixedly installed at the lower end of the auxiliary shaft 41, and the stirring wheel 44 is rotatably mounted on the inner bottom of the mixing drum 14. Spiral blades 45 are fixedly provided on the outer surface of the stirring wheel 44; the auxiliary shaft 41 receives power from the gear transmission, driving the entire auxiliary stirring structure to operate synchronously; the bottom stirring wheel 44 and spiral blades 45 are adapted to the internal space of the mixing drum 14, pushing the slurry upwards when rotating forward and discharging the slurry downwards when rotating in reverse, thus achieving forced circulation and feeding / discharging switching of the slurry inside the mixing drum, enhancing the local mixing effect, and eliminating the need for tank clogging. Edge mixing dead zones; the driven helical gear 26 drives the auxiliary shaft 41 to rotate synchronously. During mixing, the mixing wheel 44 and the spiral blade 45 rotate clockwise, pushing the slurry inside the mixing drum 14 upward to circulate and enhance local mixing; after mixing, the entire structure reverses, driving the material inside the mixing drum 14 downward to complete the unloading operation; a folding blade 43 is fixedly installed in the middle of the auxiliary shaft 41, and a defoaming rake 42 is fixedly installed at the upper end of the auxiliary shaft 41, with the defoaming rake 42 positioned above the mixing drum 14; the folding blade 43 rotates with the auxiliary shaft 41, radially dispersing and turbulently mixing the slurry around the tank, compensating for the central dead zone. The central stirring blind zone is eliminated, achieving homogeneous stirring throughout the entire area. The defoaming rake blade 42, located in the working area at the liquid surface, continuously cuts and breaks up the foam generated during stirring, preventing foam accumulation from crowding out the effective volume and causing mineral particles to overflow, thus stabilizing the stirring conditions and discharge concentration. During the operation of the auxiliary shaft 41, the folding blade 43 continuously turbulently disperses and stirs the slurry at the edge and surrounding areas of the tank, compensating for the central stirring blind zone. Simultaneously, the upper defoaming rake blade 42 rotates continuously at the liquid surface, cutting and breaking up the foam generated during stirring, ensuring no foam accumulation in the tank throughout the process and stabilizing the stirring conditions. The stirring impeller 44 has a frustum structure, with spiral blades 45 evenly fixed on the stirring wheel. The circumferential side of the mixing wheel 44; the frustum-shaped mixing wheel 44 is adapted to the bottom space structure of the mixing drum 14, with uniform rotational resistance and stable operation; the evenly distributed spiral blades 45 on the circumference can form a stable axial pushing flow field, with uniform forward rotation for lifting and reverse rotation for lowering, ensuring that the slurry circulation volume inside each mixing drum is consistent and the mixing quality is uniform; when the equipment is running, the frustum-shaped mixing wheel 44 rotates smoothly in contact with the bottom space of the mixing drum 14, and the evenly distributed spiral blades 45 form a regular axial flow field, ensuring that the material circulation volume of each mixing drum is consistent, uniformly completing the slurry lifting and mixing and reverse unloading actions, and ensuring the uniform mixing quality of the whole machine.

[0023] Using the above technical solution, a blower blade 32 is installed at the upper end of the central shaft 31, and a defoaming rake blade 42 is installed at the upper end of the auxiliary shaft 41. During the stirring operation, the blower blade 32 rotates to generate directional airflow, which evenly blows the foam gathered in the center of the tank to the surrounding liquid surface. This, combined with multiple sets of defoaming rake blades 42 arranged in a ring, rotates at high speed to cut and break up the surface foam. Compared with natural defoaming and chemical defoaming, this structure requires no additional consumables, can eliminate stirring foam in real time and continuously, avoids foam accumulation that occupies the effective volume of the tank, and prevents material loss caused by entraining fine mineral particles. At the same time, it stabilizes the liquid surface conditions, ensures uniform discharge concentration, accurate sampling and testing, and improves the stability of the mineral processing process.

[0024] By adopting the above technical solution, a stirring plate 34 is set inside the hopper 12, which can continuously agitate and push the slurry in the low-speed zone at the bottom, avoiding the deposition and compaction of high-concentration, high-density slurry at the bottom of the hopper; at the same time, the auxiliary stirring mechanism 4 adopts a frustum-shaped stirring wheel 44 with uniformly arranged spiral blades 45, which is adapted to the bottom space of the mixing cylinder 14, with low operating resistance and uniform material pushing, which can continuously drive the circulation of high-concentration slurry, reduce the frequency of cleaning, improve the continuous operation capability of the equipment, and adapt to the production needs of large-volume, high-concentration slurry mixing.

[0025] Further reading is available. Figure 1-3 The top seat 15 and the transmission box 22 both have a cross-shaped cross section when viewed from above, and the end positions of the top seat 15 and the transmission box 22 correspond one-to-one with the mixing cylinder 14. The cross-shaped structure can match the symmetrical arrangement of the four auxiliary stirring mechanisms, with a reasonable spatial layout and uniform force distribution. The one-to-one correspondence between the ends and the mixing cylinder 14 ensures that the assembly and alignment of each auxiliary shaft and stirring structure are accurate, and there is no interference in the transmission. This ensures that the four mixing cylinders work synchronously and evenly, and guarantees the stability and symmetry of the multi-group linkage stirring of the whole machine. During the assembly and operation of the equipment, the cross-shaped top seat 15 and the transmission box 22 symmetrically support the four auxiliary stirring structures, accurately corresponding to the position of each mixing cylinder 14, ensuring that the operation of the multi-group stirring and transmission structures is free from interference, and that they work synchronously and evenly throughout the process, maintaining a stable and symmetrical stirring flow field of the whole machine.

[0026] Example 2: Please see Figures 1 to 7As shown, based on Embodiment 1, the present invention provides a technical solution: the drive mechanism 2 includes a transmission box 22, which is fixedly installed on the upper side of the top seat 15. A drive motor 21 is fixedly installed on the top of the transmission box 22, and the output end of the drive motor 21 is fixedly connected to the central stirring mechanism 3. The transmission box 22 provides protection and installation cavity for the internal linkage transmission components, avoiding the corrosion of transmission components by mineral dust and water vapor, and improving the service life of the equipment. The drive motor 21 provides the only power input for the whole machine, and drives the central stirring mechanism 3 to operate through the main output end, providing a power basis for multiple sets of linkage stirring, realizing single motor drive of multiple shaft synchronous operation, reducing equipment energy consumption and power distribution costs. After the equipment is started, the drive motor 21 is energized and outputs power, which is input to the central stirring mechanism 3. The transmission box 22 provides sealed protection for the internal gears, transmission shafts and other transmission components, and relies on the internal transmission structure to divert power, synchronously driving multiple sets of auxiliary stirring mechanisms 4 to work together, realizing single power drive of the whole machine stirring operation.

[0027] Further reading is available. Figure 1-6 The drive mechanism 2 also includes a central helical gear 23 and a bearing housing 27. The central helical gear 23 is fixedly mounted on the upper end of the central shaft 31, and the bearing housing 27 is fixedly mounted on the upper side of the top seat 15. A drive shaft 24 is rotatably mounted inside the bearing housing 27. Both ends of the drive shaft 24 are fixedly fitted with drive helical gears 25, and the upper end of the auxiliary stirring mechanism 4 is fixedly fitted with a driven helical gear 26. The drive shaft 24 meshes with the central helical gear 23 and the driven helical gear 26 respectively through the drive helical gears 25 at both ends. The central helical gear 23 rotates synchronously with the central shaft 31 and serves as the core component for power distribution. The bearing housing 27 provides rotational support for the drive shaft 24 to ensure stable operation of the transmission structure. The drive shaft 24 and the two-end drive helical gears 25 form a power splitting transmission assembly, which synchronously transmits the power of the central shaft to the driven helical gear 26. Through gear meshing, a single motor drive and synchronous linkage operation of the central and auxiliary shafts are realized, eliminating the need for independent drive of multiple motors and realizing synchronous operation of multiple sets of stirring, ensuring the coordinated and stable flow field in the tank. When the central shaft 31 rotates, it drives the central helical gear 23 to rotate synchronously. The bearing seat 27 supports the drive shaft 24 to rotate smoothly. Through the meshing transmission of the two-end drive helical gears 25, the central power is synchronously split and transmitted to each set of driven helical gears 26, thereby driving multiple sets of auxiliary stirring mechanisms 4 to work synchronously with the central stirring mechanism 3, realizing coordinated stirring of the whole machine.

[0028] By adopting the above technical solution, the central helical gear 23, transmission helical gear 25, transmission shaft 24, and driven helical gear 26 inside the drive mechanism 2 form an integrated linkage transmission system. Only a single drive motor 21 is needed to synchronously drive the central shaft 31 and the four sets of auxiliary shafts 41. Compared with the traditional multi-motor independent drive or single-shaft stirring structure, multiple independent power units are eliminated, simplifying the overall structure, reducing equipment manufacturing costs and power distribution load, while ensuring that the speed and phase of the central stirring mechanism 3 and the auxiliary stirring mechanism 4 are highly consistent, and the flow field in the tank is coordinated and stable, avoiding turbulence and uneven stirring problems caused by the speed difference of multiple shafts.

[0029] By switching the drive motor 21 to forward and reverse rotation, the working mode of the equipment can be quickly switched: in the forward rotation state, the spiral blade 45 and the stirring blade 34 push the material upward synchronously to realize the circulation and mixing of the slurry in the tank, and the homogenization and conditioning; in the reverse rotation state, each stirring structure operates in the opposite direction synchronously, the material inside the mixing drum 14 flows out from the mixing port 16, and the bottom stirring blade 34 forcibly pushes the material in the hopper 12 to be discharged from the discharge port 13. The unloading is fast and there is no residue, which effectively shortens the process turnaround time and improves the overall production efficiency.

[0030] The working principle and usage process of this invention are as follows: When in use, slurry and liquid medicine are added into the stirring tank 1, and the drive motor 21 is started; the drive motor 21 drives the central shaft 31 to rotate, and the central shaft 31 synchronously drives the central helical gear 23 to rotate; the central helical gear 23 transmits power through the transmission helical gear 25 and the transmission shaft 24, driving the driven helical gear 26 to rotate, and finally realizing the synchronous linkage rotation of the auxiliary shaft 41. When the auxiliary shaft 41 is running, it drives the bottom stirring wheel 44 and the spiral blade 45 to rotate together, pushing the slurry liquid inside the mixing cylinder 14 to flow upward; at the same time, the folding blade 43 in the middle of the auxiliary shaft 41 stirs the material in the tank in a full range, and the defoaming rake blade 42 at the top rotates continuously to break the foam generated during the stirring process; the blower blade 32 at the top of the central shaft 31 rotates synchronously, and the airflow generated blows the foam in the central area of ​​the tank to the surrounding area, which works with the defoaming rake blade 42 to complete the full defoaming operation; The stirring blades 34 at the lower end of the central shaft 31 rotate in the hopper 12, pushing the bottom slurry and liquid upwards; after the material rises to the mixing port 16, it is sucked into the mixing cylinder 14; at the same time, the stirring rod 33 on the central shaft 31 performs secondary stirring on the material surging in the middle of the tank; after the material completes the circulation, it falls back and enters the mixing cylinder 14 again through the mixing port 16, forming continuous circulation stirring and improving the mixing effect of slurry and liquid. After the mixing operation is completed, the drive motor 21 is controlled to rotate in reverse, driving the central shaft 31 and the auxiliary shaft 41 to rotate synchronously in reverse; the auxiliary shaft 41 drives the mixing wheel 44 and the spiral blade 45 to rotate in reverse, so that the slurry in the mixing drum 14 flows out from the mixing port 16; the mixing blade 34 at the bottom of the central shaft 31 rotates synchronously in reverse, pushing the material in the hopper 12 to be discharged through the discharge port 13, completing the unloading process of the entire equipment.
