Description

Technical Field

[0001] The present invention relates to the technical field of ternary precursor processing, and specifically to a centrifugal solid-liquid separation device for ternary precursor slurry. Background Art

[0002] The ternary precursor material is nickel-cobalt-manganese hydroxide NixCoyMn(1-x-y)(OH)2. The conventional cathode material for batteries is lithium cobaltate LiCoO2. The ternary composite cathode material precursor product uses nickel salt, cobalt salt, and manganese salt as raw materials, and the ratio of nickel, cobalt, and manganese inside can be adjusted according to actual needs.

[0003] Referring to the Chinese invention patent with the publication number: CN 118976441 A and the name: A ternary precursor washing water and dehydration recycling system, which includes a production mechanism and a recycling mechanism. The production mechanism includes a reaction kettle, an aging tank, a washing device, a slurrying tank, a dehydration device, and a drying device; the recycling mechanism includes a solid-liquid separator, a liquid storage tank, and a recycling pump. The inlet of the solid-liquid separator is connected to the wastewater outlet of the washing device and the wastewater outlet of the dehydration device. The beneficial effect of the ternary precursor washing water and dehydration recycling system provided by this invention is that the washing water and dehydration generated during the washing and dehydration processes are introduced into the solid-liquid separator for solid-liquid separation. The solid is discharged from the solid material outlet of the solid-liquid separator and then introduced into the aging tank. The water obtained from the solid-liquid separation enters the liquid storage tank and is then pumped into the reaction kettle by the recycling pump as reaction water. The present invention realizes the recycling of ternary precursor washing water and dehydration, reduces the amount of production wastewater, reduces the amount of pure water used in production, and lowers the production cost. However, in the actual use process, there are still some problems: The ternary precursor slurry needs to be subjected to solid-liquid separation through a centrifugal device. The centrifugal device discharges the liquid and solid from both ends, but the centrifugal device cannot completely drain the water in the solid. During the discharge process of the solid, it agglomerates or blocks inside the slag discharge hole. Over time, the blocked slag discharge holes are adhered and accumulated by solids, affecting the subsequent solid-liquid separation efficiency. Secondly, after the device is used, there is still a certain amount of water vapor inside. If it cannot be cleaned in time, the water vapor adheres to the inside of the device and corrodes its internal parts, reducing the service life of the device. Secondly, when the solid is discharged, there is still water inside, causing the solids to stick to each other and finally form agglomerates, making it difficult for the water to volatilize. Summary of the Invention

[0004] Technical Problems to be Solved The object of the present invention is to make up for the deficiencies in the prior art when solid-liquid separation is carried out on ternary precursor slurries. When using a centrifugal device for solid-liquid separation, the liquid and solid are discharged from both ends, but the centrifugal device cannot completely dry the moisture in the solid. During the discharge process of the solid, it may agglomerate or block inside the slag discharge hole. Over time, the blocked slag discharge holes will cause the solids to adhere and accumulate to each other, affecting the subsequent solid-liquid separation efficiency. Secondly, after the device is used, there is still a certain amount of water vapor inside. If it cannot be cleaned in time, the water vapor will adhere to the inside of the device, corrode its internal parts, and reduce the service life of the device. Secondly, when the solid is discharged, there is still moisture inside, causing the solids to stick to each other and finally form agglomerates, making it difficult for the moisture to volatilize.

The blowing troughs are respectively fixedly connected to the outside of the connecting grooves, and the warm air blower is fixedly connected to the surface of the frame.

[0015] Compared with the prior art, the ternary precursor slurry centrifugal solid-liquid separation device has the following beneficial effects: First, in the present invention, by controlling the electric push rod to drive the connecting cover and the sealing ring to move towards the slag discharge cover, the extension pipe is stretched and extended with the connecting cover until the connecting cover completely moves to the outside of the slag discharge cover. Then, the convex part of the track block slowly moves to the top of the limit ring. At this time, the limit ring is driven by the downward pressure to drive the insertion pipe to insert into the slag discharge hole along the insertion hole. At the same time, the telescopic pipe is stretched and extended. Then, the blower is started to evenly disperse the wind along the connecting pipe, the extension pipe, and the annular pipe into the shunt pipe, and then blown out from the bottom of the insertion pipe along the telescopic rod. This is beneficial to quickly clean the residues in the inspection hole, avoid blockage caused by long-term use, which affects subsequent solid-liquid separation. Secondly, it ventilates the working area of the equipment to ensure the dryness inside the equipment and avoid the corrosion of internal parts by residual water vapor, which affects the service life of the equipment.

[0016] Second, in the present invention, the sleeve slides towards one end of the driving rod. Then, the driving gear follows the movement of one end of the sleeve. Subsequently, the driving motor is started to drive the driving rod through the sprocket and the chain at the same time, so that the driving rod drives the sleeve to rotate through the limiting strip. The driving gear is driven to drive the driving ring to rotate through the transmission teeth. Therefore, when the blockage removal mechanism moves, the transmission structure can follow its trajectory and the normal starting mechanism can clean the equipment. Secondly, it avoids hindering the operation of internal parts during the operation of the equipment.

[0017] Third, in the present invention, by starting the servo motor to drive the driving shaft to rotate, at the same time, the eccentric column is driven to drive the vibrating plate to vibrate up and down through the track cover and the connecting frame. When the solid falls from the connecting funnel to the opposite side of the vibrating plate, it impacts the vibrating plate under the influence of vibration. Then, the warm air blower is started to send hot air into the blowing trough through the external connecting pipe until it is evenly blown into the intervals of the vibrating plate. This is beneficial to re-dry the discharged solid, ensure that the liquid content is further reduced, and secondly, break up the lumps, which is convenient for drying and ensures the uniformity of the ternary precursor material.

[0018] Other advantages, objectives, and features of the present invention will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention.

[0023] As Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the blockage removal mechanism 14 includes a connecting cover 1401, an electric push rod 1402, a driving ring 1403, and a track block 1404. The connecting cover 1401 is cylindrical. A plurality of jacks 18 are provided on the outer side of the connecting cover 1401, and every three of the jacks 18 are arranged in a circular array on the outer side of the connecting cover 1401.

The other ends of the electric push rods 1402 are fixedly connected to the inner end of the housing 1. There are two driving rings 1403 and transmission teeth 19 are provided on their outer sides. The two sides of the driving ring 1403 are rotatably connected to the outer side of the connecting cover 1401. The track block 1404 is arc-shaped, and the track blocks 1404 are respectively fixedly connected to the inner side of the driving ring 1403 in a circular array. The blockage removal mechanism 14 further includes an insertion tube 1405, a limiting ring 1406, a telescopic tube 1407, a shunt tube 1408, and an annular tube 1409. There are several shunt tubes 1408 and they are fixedly connected to the outer side of the annular tube 1409 in a circular array. There are several insertion tubes 1405 and they respectively correspond to each jack 18. The limiting rings 1406 are respectively fixedly connected to the outer sides of the insertion tubes 1405. The telescopic tubes 1407 are respectively fixedly connected to the tops of the insertion tubes 1405, and the other ends of the telescopic tubes 1407 are respectively connected to the shunt tubes 1408.

One end of the insertion tube 1405 away from the telescopic tube 1407 is adapted to the jack 18 and the slag discharge hole 12. The diameter of the limiting ring 1406 is larger than that of the jack 18.

[0024] By controlling the electric push rod 1402 to drive the connecting cover 1401 and the sealing ring 13 to move towards the slag discharge cover 11, the extension tube 23 is stretched and extended with the connecting cover 1401 until the connecting cover 1401 completely moves to the outside of the slag discharge cover 11. Then, the convex part of the track block 1404 slowly moves to the top of the limiting ring 1406. At this time, the limiting ring 1406 is driven by the downward pressure to drive the insertion tube 1405 to insert into the slag discharge hole 12 along the jack 18. At the same time, the telescopic tube 1407 is stretched and extended, which is beneficial to quickly clean the residues in the inspection hole and avoid blockage caused by long-term use, affecting the subsequent solid-liquid separation.

[0025] As Figure 1 、 Figure 3 and Figure 5As shown, a blower 20 is fixedly connected inside the frame 2, and an output end of the blower 20 is fixedly connected with a connecting pipe 21. One end of the connecting pipe 21 penetrates through the housing 1 and extends to its interior. The end of the connecting pipe 21 away from the blower 20 is fixedly connected with an extension pipe 23, and the other end of the extension pipe 23 is fixedly connected to the outside of the annular pipe 1409 and is in communication with it.

[0026] Start the blower 20 to evenly disperse the wind along the connecting pipe 21, the extension pipe 23, and the annular pipe 1409 into the shunt pipe 1408 in sequence, and then blow it out from the bottom of the insertion pipe 1405 along the telescopic rod to ensure the dryness inside the equipment, avoid residual water vapor from corroding the internal parts, and affect the service life of the equipment. As Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the control mechanism 15 includes a control motor 1501, a driving rod 1502, a sprocket 1503, a chain 1504, a limiting strip 1505, a sleeve 1506, and a driving gear 1507. There are two driving rods 1502 and they are symmetrically arranged. The limiting strips 1505 are symmetrically fixedly connected to the outside of the driving rods 1502 respectively. The connection cross-section of the driving rod 1502 and the limiting strip 1505 is adapted to the sleeve 1506. The sleeve 1506 is slidably connected to the outside of the driving rod 1502. The driving gear 1507 is fixedly connected to one end of the sleeve 1506. The sprockets 1503 are fixedly connected to the ends of the driving rods 1502 away from the driving gear 1507 respectively, and the two sprockets 1503 are drivingly connected by a chain 1504. The output end of the control motor 1501 is fixedly connected to the axis of one of the sprockets 1503 through a coupling. The control motor 1501, the sprocket 1503, and the chain 1504 are all located at the outer end of the housing 1. The driving rod 1502 and the sleeve 1506 both penetrate through the housing 1 and extend to its interior, and the connection of the sleeve 1506 to the housing 1 is slidably connected. The driving gears 1507 are respectively meshed with the two driving rings 1403 through transmission teeth 19, and the outside of the sleeve 1506 is fixedly connected to the outside of the connection cover 1401 through a connecting member.

[0027] Slide the sleeve 1506 towards one end of the driving rod 1502. Secondly, the driving gear 1507 moves along with one end of the sleeve 1506. Then start the driving motor 10 to drive the driving rods 1502 simultaneously through the sprockets 1503 and the chain 1504, so that the driving rods 1502 drive the sleeve 1506 to rotate through the limiting strips 1505. The driving gear 1507 is driven to drive the driving ring 1403 to rotate through the transmission teeth 19. Thus, when the plug removal mechanism 14 is displaced, it is beneficial for the transmission structure to move along with its trajectory and the normal starting mechanism to clean the equipment, and secondly, to avoid hindering the operation of the internal parts during the operation of the equipment.

[0028] As Figure 1 , Figure 2 , Figure 8 and Figure 9 shown, the drying and discharging mechanism 17 includes a connecting funnel 1701, a drive shaft 1702, a servo motor 1703, an eccentric column 1704, a track cover 1705, a connecting frame 1706 and a vibrating plate 1707. The drive shaft 1702 is horizontally movably connected to the inside of the connecting funnel 1701, and one end of the drive shaft 1702 penetrates through the connecting funnel 1701 and is fixedly connected to the output end of the servo motor 1703. The eccentric column 1704 is fixedly connected to the outside of the drive shaft 1702, and the track cover 1705 is sleeved on the outside of the eccentric column 1704. The connecting frames 1706 are symmetrically and fixedly connected to the outside of the track cover 1705. A plurality of vibrating plates 1707 are respectively fixedly connected to the outside of the connecting frames 1706. The drying and discharging mechanism 17 further includes a warm air blower 1708, an outer connecting pipe 1709 and a blowing groove 1710. One end of the outer connecting pipe 1709 is fixedly connected to the output end of the warm air blower 1708, and the other end of the outer connecting pipe 1709 is bifurcated and fixedly connected to the conveying port of the blowing groove 1710. The connecting funnel 1701 is fixedly connected to the bottom end of the slag discharge port 16, and connecting grooves 22 are formed on both sides inside the connecting funnel 1701. The blowing grooves 1710 are respectively fixedly connected to the outside of the connecting grooves 22. The warm air blower 1708 is fixedly connected to the surface of the frame 2.

[0029] By starting the servo motor 1703 to drive the drive shaft 1702 to rotate, at the same time, the eccentric column 1704 is driven to drive the vibrating plate 1707 to vibrate up and down through the track cover 1705 and the connecting frame 1706. When the solid falls from the connecting funnel 1701 to the opposite side of the vibrating plate 1707, it impacts the vibrating plate 1707 under the influence of vibration. Then, the warm air blower 1708 is started to send hot air into the blowing groove 1710 through the outer connecting pipe 1709 until it is evenly blown into the interval of the vibrating plate 1707, which is beneficial to drying the discharged solid again, ensuring that the liquid content is further reduced. Secondly, the lumps are broken, which is convenient for drying and ensures the uniformity of the ternary precursor material.

[0030] Working principle: After the ternary precursor slurry is subjected to solid-liquid separation by the feeding screw 8, the feeding screw 8 pushes the separated solid towards the slag discharge hood 11 until it is thrown out from the slag discharge hole 12 by centrifugal force, and then falls into the connecting funnel 1701 through the slag discharge port 16. At this time, the servo motor 1703 is started to drive the drive shaft 1702 to rotate. At the same time, the eccentric column 1704 is driven to drive the vibrating plate 1707 to vibrate up and down through the track cover 1705 and the connecting frame 1706. When the solid falls from the connecting funnel 1701 to the opposite side of the vibrating plate 1707, it impacts the vibrating plate 1707 under the influence of vibration. Then, the warm air blower 1708 is started to send hot air into the air supply groove 1710 through the external connecting pipe 1709 until it is evenly blown into the interval of the vibrating plate 1707. The equipment is shut down. At this time, the electric push rod 1402 is controlled to drive the connecting hood 1401 and the sealing ring 13 to move towards the slag discharge hood 11, and the extension pipe 23 is stretched and extended with the connecting hood 1401 until the connecting hood 1401 completely moves to the outside of the slag discharge hood 11. During this process, the connecting hood 1401 pulls the sleeve 1506 to move in the same track through the connecting frame 1706. At the same time, the sleeve 1506 slides towards one end of the drive rod 1502. Secondly, the drive gear 1507 moves along with one end of the sleeve 1506. Then, the drive motor 10 is started to drive the drive rod 1502 simultaneously through the sprocket 1503 and the chain 1504, so that the drive rod 1502 drives the sleeve 1506 to rotate through the limiting strip 1505. The drive gear 1507 is driven to drive the drive ring 1403 to rotate through the transmission teeth 19. Then, the protruding part of the track block 1404 slowly moves to the top of the limiting ring 1406. At this time, the limiting ring 1406 drives the insertion pipe 1405 to insert into the inside of the slag discharge hole 12 along the jack 18 under the downward pressure, and at the same time, the telescopic pipe 1407 is stretched and extended. Secondly, the fan 20 is started to evenly disperse the wind along the connecting pipe 21, the extension pipe 23, and the annular pipe 1409 into the shunt pipe 1408, and then blows out from the bottom of the insertion pipe 1405 along the telescopic rod.
