Description

Technical Field

[0001] This invention relates to the field of solid-liquid separation equipment technology, specifically a solid-liquid separation device for mining. Background Technology

[0002] Before entering the beneficiation process, minerals must first undergo crushing and grinding. During crushing and grinding, some extremely fine-grained slime may be generated. Excessive slime can severely affect subsequent beneficiation, impacting beneficiation recovery rates, increasing the consumption of beneficiation reagents, and increasing the load on beneficiation equipment. Therefore, solid-liquid separation equipment is needed to separate coarse sand and slime from the slurry.

[0003] Existing mining solid-liquid separation equipment connects directly to upstream mineral crushing or grinding equipment via pipelines, allowing minerals to be directly injected into the separator for separation. Due to the varying content of coarse sand and slime after mineral crushing, the content of coarse sand and slime in the mineral slurry is constantly changing. If the density of the mineral slurry is too high or too low, it will not meet the optimal separation density range of the hydrocyclone, resulting in an unsatisfactory desliming effect, affecting subsequent mineral beneficiation, and causing the loss of effective mineral components. Summary of the Invention

[0004] This invention provides a solid-liquid separation device for mining, which uses multiple stirring blades to create two intersecting vortices while simultaneously rotating on their own axis. This ensures that the slurry is thoroughly stirred and mixed evenly. The slurry is then injected into a hydrocyclone, thereby achieving the optimal separation density of the hydrocyclone. This results in the complete separation of coarse sand and sludge in the slurry, achieving excellent desliming effects and avoiding mineral loss. Furthermore, the invention achieves the beneficial effect of intelligent control of the stirring device and valve body, which alternately operate to reduce the error rate of manual operation, thus solving the problems mentioned in the background art.

[0025] The present invention has the following beneficial effects:

[0026] 1. Before the slurry is injected into the hydrocyclone separator for separation, the slurry is first injected into the mixing tank. The first rotating component drives multiple mixing blades to rotate on their own axis while revolving around the center, forming two intersecting vortices to fully mix the slurry and make it uniform. Then it is injected into the hydrocyclone separator so that the density of the mixed fluid in the hydrocyclone separator reaches the optimal working range of the hydrocyclone separator, thereby achieving the best desliming effect and avoiding incomplete separation of coarse sand and sludge due to excessively high or low density.

[0027] 2. This mining solid-liquid separation equipment achieves intelligent operation through a PLC controller, a water level monitor, and intermittent drive components. When the dual-axis motor rotates in the forward direction, the second rotating component does not operate, and the valve body is in the closed state. The first rotating component operates, causing the slurry to be injected into the mixing tank while being stirred. When the water level reaches the set threshold of the water level monitor, the PLC controller controls the dual-axis motor to rotate in the reverse direction. At this time, the first rotating component stops operating and thus stops stirring, and the injection of slurry is stopped. The second rotating component then operates to open the valve body, allowing the uniformly mixed slurry to be automatically injected into the cyclone separator through the valve body.

[0028] 3. This mining solid-liquid separation equipment has multiple valve bodies and cyclone separators. It can simultaneously inject the mixed slurry in the mixing tank into multiple cyclone separators for cyclone desliming. On the one hand, it can improve the desliming efficiency. On the other hand, by diverting the flow, it can also avoid the flow rate of the fluid received in the cyclone separator being too large and exceeding its processing speed, thus preventing incomplete separation.

Detailed Implementation

[0041] 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.

[0042] Example 1, please refer to Figures 1-11 A mining solid-liquid separation device includes an upper shell 100, a plurality of first circular grooves 110 are provided on the lower inner wall of the upper shell 100, and a stirring tank 200 is provided on the lower inner wall of the upper shell 100. The stirring tank 200 is provided with a first feed inlet 210 and a plurality of first discharge outlets 220.

[0043] Each of the first circular troughs 110 is provided with a cyclone separator 300, and the cyclone separator 300 is provided with a second inlet 310 and two second outlets 320.

[0044] The lower end of the upper shell 100 is provided with a lower shell 120, the lower shell 120 is provided with a third discharge port 130, the lower inner wall of the lower shell 120 is provided with a second circular groove 140, the second circular groove 140 is provided with a receiving cylinder 150, and the receiving cylinder 150 is provided with a fourth discharge port 160.

[0045] The upper housing 100 is provided with a mixing mechanism 400, which includes a first rotating component 410, two second rotating rods 420 and several stirring blades 430;

[0046] Both second rotating rods 420 are disposed inside the mixing tank 200, and the two second rotating rods 420 are axially symmetrical about the midpoint of the upper inner wall of the mixing tank 200. Multiple stirring blades 430 are respectively disposed on the circumferential surface of the two second rotating rods 420. The first rotating component 410 is connected to both second rotating rods 420 so that it can perform a circular motion about the midpoint of the upper inner wall of the mixing tank 200 while rotating about its own central axis, thereby causing the multiple stirring blades 430 to form two intersecting vortices to stir the material in the mixing tank 200.

[0047] It also includes several conveying mechanisms 500, each of which includes a second rotating component 510, a first pipe 520, a second pipe 530, a valve body 540, and a ball 550.

[0048] One end of the valve body 540 is connected to one of the second feed ports 310. The ball 550 is rotatably connected to the inner circumference of the valve body 540. One end of the first pipe 520 is connected to one of the first discharge ports 220. The other end of the first pipe 520 is connected to the other end of the valve body 540. One end of the second pipe 530 is connected to one of the second discharge ports 320. The other end of the second pipe 530 passes through the lower end of the upper housing 100 and extends downward. The second rotating component 510 is connected to the ball 550 to realize its rotation, thereby opening and closing the second feed port 310.

[0049] In this embodiment: the upper end of the lower housing 120 is open, and a second circular groove 140 is formed in the middle of its lower inner wall. A receiving cylinder 150 is fixed in the second circular groove 140. The upper end of the receiving cylinder 150 is open. A third discharge port 130 is provided at the left end of the lower housing 120 and communicates with the interior of the lower housing 120. A fourth discharge port 160 is provided at the right end of the receiving cylinder 150 and communicates with the interior of the receiving cylinder 150. The fourth discharge port 160 passes through the right end of the lower housing 120 and extends to the right. The front end of the upper housing 100 is open, and five evenly distributed first circular grooves 110 are formed in the lower inner wall of the upper housing 100.

[0050] Each of the five first circular troughs 110 contains a hydrocyclone separator 300. Each of the hydrocyclone separators 300 has a second discharge port 320 at both its upper and lower ends. The upper discharge ports 320 are overflow ports used to discharge smaller particles of sludge. The lower discharge ports 320 are sand discharge ports used to discharge larger particles of coarse sand. All the coarse sand discharge ports face downwards and are aligned with the lower inner wall of the lower casing 120. Each overflow port has a second pipe 530 fixed inside it.

[0051] Multiple second pipes 530 penetrate the lower end of the upper shell 100 and are aligned with the opening at the upper end of the receiving cylinder 150. A mixing tank 200 is fixed in the middle of the lower inner wall of the upper shell 100. A first feed inlet 210 is provided on the left side of the circumferential surface of the mixing tank 200 for injecting slurry. Five evenly distributed first discharge outlets 220 are provided at the lower end of the mixing tank 200 for discharging slurry. The five second feed inlets 310 are respectively connected to the five first discharge outlets 220 through five first pipes 520 and five valve bodies 540.

[0052] The valve body 540 has openings at both the left and right ends, and a spherical groove is provided inside. A hollow ball 550 is rotatably connected inside the spherical groove. The ball 550 rotates horizontally along the spherical groove. The front and rear parts of the circumference of the ball 550 are also open.

[0053] In the initial state, the two openings on the five spheres 550 are perpendicular to the two openings on the five valve bodies 540, respectively. At this time, the five valve bodies 540 are closed, preventing the slurry from entering the five cyclone separators 300. In the drive mechanism 600, the intermittent drive component 610 alternately drives the first transmission component 620 and the second transmission component 630. When one of them is operating, the other automatically stops.

[0054] During the desliming operation, the untreated slurry is injected into the mixing tank 200 through the first feed inlet 210. The intermittent drive component 610 drives the first transmission component 620 to operate. At this time, the second transmission component 630 is not operating and the five valve bodies 540 are in the closed state. The first transmission component 620 drives the first rotating component 410 to operate, which in turn drives the two second rotating rods 420 to rotate around the midpoint of the mixing tank 200 while rotating around their own midpoint. This causes the multiple stirring blades 430 on the two second rotating rods 420 to rotate around the midpoint while revolving around the midpoint, forming two intersecting vortices that fully mix the slurry, and the mud and coarse sand are evenly distributed in the slurry.

[0055] Then, the intermittent drive component 610 will drive the second transmission component 630 to operate and stop the first transmission component 620. The second transmission component 630 will drive the second rotating component 510 to operate, thereby driving the five valve bodies 540 to rotate in the horizontal direction until the openings on the five valve bodies 540 coincide with the openings on the five balls 550, so that the five valve bodies 540 open. Thus, the mixed slurry will naturally enter the five first pipes 520 through the five first discharge ports 220 under the action of gravity.

[0056] The mixing tank 200 has a fixed volume. The water level monitor 700 is set up to monitor whether the material in the tank has reached the optimal processing capacity. When mixing stops, the PLC controller 800 receives the water level signal, and its logic determines that a batch of material has been mixed and should enter the discharge stage. Therefore, it first issues a stop signal, and then initiates the valve opening procedure. This is a PLC-based automated process control.

[0057] Then, the slurry is injected tangentially into five hydrocyclone separators 300 through five valve bodies 540 and five second inlets 310. Under centrifugal force, the slurry forms two vortex flow fields on the inner circumference of the five hydrocyclone separators 300. The lighter slurry is discharged from the five overflow ports into the five second pipes 530 through the inner vortex flow field.

[0058] The slurry is then injected into the receiving cylinder 150 via five second pipes 530 and discharged through the fourth discharge port 160. Heavier coarse sand is discharged from the five settling ports through the outer vortex flow field and injected into the lower shell 120, and discharged through the third discharge port, thus completing the desliming operation of the slurry. For those skilled in the art, the internal structure of the cyclone separator 300 described above is prior art and will not be described in detail.

[0059] Example 2 is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-10 It also includes a drive mechanism 600, which includes an intermittent drive component 610, a first transmission component 620, and a second transmission component 630.

[0060] The intermittent drive component 610 is connected to the first rotating component 410 through the first transmission component 620, and the intermittent drive component 610 is connected to the second rotating component 510 through the second transmission component 630. The first rotating component 410 and the second rotating component 510 operate alternately.

[0061] The first rotating component 410 includes a first rotating rod 411, a turntable 412, a turntable groove 413, an internal gear 414, and two first straight gears 415;

[0062] A turntable groove 413 is formed on the inner circumference of the mixing tank 200. The turntable 412 is rotatably connected to the turntable groove 413. One end of the first rotating rod 411 is rotatably connected to the upper inner wall of the upper shell 100. The other end of the first rotating rod 411 moves through the upper inner wall of the mixing tank 200 and is connected to the upper end of the turntable 412. Two second rotating rods 420 are rotatably connected to the lower end of the turntable 412. Two first spur gears 415 are respectively connected to the circumferential surfaces of the two second rotating rods 420. An internal gear 414 is connected to the inner circumferential wall of the mixing tank 200, and the internal gear 414 meshes with both first spur gears 415.

[0063] The second rotating component 510 includes two third rotating rods 511. The close ends of the two third rotating rods 511 are connected to the circumferential surface of one of the balls 550. The far ends of the two third rotating rods 511 respectively movably pass through the upper and lower ends of one of the valve bodies 540 and extend outward. One of the third rotating rods 511 is rotatably connected to the lower inner wall of the upper housing 100.

[0064] The first transmission component 620 includes a fifth rotating rod 621 and two second spur gears 622. The fifth rotating rod 621 is rotatably connected to the upper inner wall of the upper housing 100. The two second spur gears 622 are respectively connected to the circumferential surfaces of the first rotating rod 411 and the fifth rotating rod 621, and the two second spur gears 622 mesh with each other.

[0065] The second transmission component 630 includes a chain 631, two sixth rotating rods 632, two third spur gears 633, and a plurality of fourth spur gears 634. The two sixth rotating rods 632 are rotatably connected to the lower inner wall of the upper housing 100. The two third spur gears 633 are respectively connected to the circumferential surfaces of the two sixth rotating rods 632 and the two third spur gears 633 mesh with each other. The plurality of fourth spur gears 634 are respectively connected to the circumferential surfaces of the plurality of third rotating rods 511. The chain 631 is drivenly connected to the circumferential surfaces of the plurality of fourth spur gears 634 and one of the third spur gears 633.

[0066] The intermittent drive component 610 includes a dual-axis motor 611, two second fixed disks 612, and two sets of connecting components 613. The dual-axis motor 611 is connected to one side inner wall of the upper housing 100, and the two second fixed disks 612 are respectively connected to the close ends of one of the second spur gears 622 and one of the third spur gears 633.

[0067] The connecting assembly 613 includes a fourth rotating rod 6131, a first fixed plate 6132, an inner ratchet 6133, a rotating block 6134, two pawls 6135, and two springs 6136. The fourth rotating rod 6131 is connected to one of the output ends of the dual-axis motor 611. The first fixed plate 6132 is connected to the upper end of the fourth rotating rod 6131. ​​The rotating block 6134 is connected to the upper end of the first fixed plate 6132. Both pawls 6135 are rotatably connected to the upper end of the first fixed plate 6132. The close ends of the two springs 6136 are respectively connected to the two side ends of the rotating block 6134, and the far ends of the two springs 6136 are respectively connected to the close ends of the two pawls 6135. The inner ratchet 6133 is connected to the lower end of one of the second fixed plates 612, and the inner ratchet 6133 and the two pawls 6135 are intermittently engaged.

[0068] When the motor rotates forward, the pawl 6135 of the upper component engages with the inner ratchet 6133, driving the stirring system; in the lower component, because the ratchet teeth are in the opposite direction, the pawl 6135 slips and spins freely. When the motor rotates in reverse, the situation is exactly the opposite. The function of the spring 6136 is to provide a continuous clamping force to the pawl 6135, ensuring that it can spring up in time and engage with the ratchet teeth, thus ensuring the reliability of the transmission.

[0069] In this embodiment: the upper end of the first rotating rod 411 rotates on the upper inner wall of the upper housing 100, and the lower end of the first rotating rod 411 moves through the upper inner wall of the mixing tank 200 and is fixed with a turntable 412. The turntable 412 rotates horizontally in the turntable groove 413 opened along the circumferential inner wall of the mixing tank 200, which plays a supporting and limiting role for the turntable 412.

[0070] Two second rotating rods 420 are mounted on the lower left and right sides of the turntable 412. Multiple evenly distributed stirring blades 430 are fixed to the circumferential surfaces of both second rotating rods 420. An internal gear 414, which is annular, is fixed to the inner circumferential wall of the mixing tank 200, with its teeth distributed along the inner circumferential wall. Rotating the first rotating rod 411 drives the turntable 412 to rotate, which in turn drives the two second rotating rods 420 and the two first spur gears 415 to rotate. The meshing of the internal gear 414 with the two first spur gears 415 causes the two first spur gears 415 to rotate as well. This causes the two second rotating rods 420 to rotate simultaneously, while revolving around the midpoint of the mixing tank 200. Consequently, the multiple stirring blades 430, rotating on their own axes while simultaneously revolving around the midpoint, form two intersecting vortices that stir the slurry within the mixing tank 200.

[0071] There are ten third rotating rods 511 in total. The lower ends of the five third rotating rods 511 located on the lower side rotate on the lower inner wall of the upper housing 100. The upper ends of the five third rotating rods 511 located on the lower side respectively move through the lower ends and circumferential inner walls of the five valve bodies 540 and are fixed to the lower part of the circumferential surface of the five balls 550.

[0072] The lower ends of the five third rotating rods 511 located on the upper side are fixed to the upper part of the circumferential surface of the five balls 550, and the upper ends of the five third rotating rods 511 located on the upper side respectively movably penetrate the inner circumferential wall and the upper end of the five valve bodies 540 and extend upward.

[0073] By rotating the five third levers 511 located on the upper side, the five balls 550 and the five third levers 511 located on the lower side can be driven to rotate, thereby controlling the opening and closing of the five valve bodies 540. Every quarter turn, the five valve bodies 540 will open or close once. Among them, the five third levers 511 located on the lower side play a role in making the rotation of the five balls 550 more stable.

[0074] A fifth rotating rod 621 is rotatably mounted on the upper inner wall of the upper housing 100. The fifth rotating rod 621 is located to the right of the first rotating rod 411. A second spur gear 622 is fixed to the circumferential surface of both the first rotating rod 411 and the fifth rotating rod 621, and the two second spur gears 622 mesh with each other. When the second spur gear 622 on the right is rotated, it drives the fifth rotating rod 621 and the second spur gear 622 on the left to rotate, thereby driving the first rotating rod 411 to rotate and thus driving the first rotating component 410 to operate. The fifth rotating rod 621 serves to support the rotation of the second spur gear 622 on the right.

[0075] The five third rotating rods 511 located on the upper side are each fixed with a fourth spur gear 634 on their circumferential surfaces. The lower inner wall of the upper housing 100 has two sixth rotating rods 632, one on the left and one on the right, which rotate on their circumferential surfaces. The third spur gear 633 and the five fourth spur gears 634 located on the right side are arranged in a hexagonal pattern. A chain 631 is engaged with the circumferential surfaces of the third spur gear 633 and the five fourth spur gears 634 located on the right side.

[0076] When the third spur gear 633 on the left is rotated, it will drive the third spur gear 633 on the right and the two sixth rotating rods 632 to rotate. In turn, through the transmission action of the chain 631, it will drive the five fourth spur gears 634 to rotate, which in turn drives the five third rotating rods 511 and the five balls 550 on the upper side to rotate, thereby controlling the opening and closing of the five valve bodies 540. The two sixth rotating rods 632 serve to support the rotation of the two third spur gears 633.

[0077] The lower end of the second spur gear 622 on the right and the upper end of the third spur gear 633 on the right are both fixed with a second fixed plate 612. The close ends of the two second fixed plates 612 are both fixed with inner ratchet wheels 6133. The two inner ratchet wheels 6133 intermittently mesh with the four pawls 6135 respectively. The teeth of the two inner ratchet wheels 6133 are in opposite directions. The teeth of the two pawls 6135 on the upper side and the two pawls 6135 on the lower side are also in opposite directions.

[0078] When the dual-axis motor 611 operates in the forward direction, its two output shafts rotate in the forward direction, which in turn drives the two fourth rotating rods 6131, the two first fixed disks 6132, the two rotating blocks 6134, and the four pawls 6135 to rotate. At this time, the rotation direction of the two lower pawls 6135 is in the same direction as the ratchet teeth of the lower inner ratchet 6133, and they are not engaged. Therefore, the two lower pawls 6135 will rotate continuously in small amplitudes under the compression and rebound action of the two springs 6136, while the lower inner ratchet 6133 will not be driven by the two lower pawls 6135.

[0079] At this time, the two third spur gears 633 will not rotate, while the two pawls 6135 located on the upper side rotate in the opposite direction to the direction of the ratchet teeth of the inner ratchet 6133 located on the upper side, and the two mesh with each other.

[0080] Therefore, the inner ratchet 6133 located on the upper side is driven by the two pawls 6135 located on the upper side, which in turn drives the two second spur gears 622 to rotate. For those skilled in the art, the above-mentioned dual-axis motor 611 is prior art and will not be described in detail.

[0081] Example 3 is an improvement upon Example 2. For details, please refer to [link / reference]. Figures 1-10 A water level monitor 700 is connected to the inner circumference of the mixing tank 200, and a PLC controller 800 is connected to one side of the lower housing 120. The PLC controller 800 is connected to the dual-axis motor 611 and the water level monitor 700.

[0082] The lower inner wall of the upper housing 100 is connected to several support frames 900, and the several support frames 900 are respectively connected to the circumferential surface of several valve bodies 540.

[0083] Several cyclone separators 300 are all bolted to the lower inner wall of the upper shell 100;

[0084] The lower inner wall of the lower housing 120 is inclined toward the third discharge port 130, and the lower inner wall of the receiving cylinder 150 is inclined toward the fourth discharge port 160.

[0085] In this embodiment: the water level monitor 700 can monitor the water level change in the mixing tank 200. When the water level in the mixing tank 200 reaches the threshold set by the water level monitor 700.

[0086] The water level monitor 700 will be triggered to transmit the water level signal to the PLC controller 800. The PLC controller 800 will control the dual-axis motor 611 to stop running in the forward direction and thus stop stirring. At the same time, it will control the dual-axis motor 611 to run in the reverse direction and thus open the five valve bodies 540 to discharge the slurry in the mixing tank 200 into the five hydrocyclone separators 300 for desliming.

[0087] Each of the five valve bodies 540 has a support frame 900 fixed at both ends of its circumferential surface, and all ten support frames 900 are fixed to the lower inner wall of the upper housing 100. This can strengthen and fix the five valve bodies 540, making them more stable during operation and preventing them from shaking.

[0088] Threaded holes are provided on the lower inner wall of the upper shell 100 and on the multiple cyclone separators 300. The multiple threaded holes are paired and matched, and bolts are threaded into the two adjacent threaded holes. This can strengthen and fix the five cyclone separators 300, so that when the slurry is injected into the five cyclone separators 300 and rotates at high speed, the five cyclone separators 300 will not shake violently and cause damage to the device.

[0089] The lower inner wall of the lower shell 120 is an inclined surface sloping towards the third discharge port 130 on the left, and the lower inner wall of the receiving cylinder 150 is an inclined surface sloping towards the fourth discharge port 160 on the right. This can help the fluid containing coarse sand and sludge to flow through the lower inner walls of the lower shell 120 and the receiving cylinder 150 and flow out through the third discharge port 130 and the fourth discharge port 160.

[0091] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
