Description

Technical Field

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

[0002] The ternary precursor material is nickel cobalt manganese hydroxide NixCoyMn(1-xy) (OH) 2. The conventional battery positive electrode material is lithium cobalt oxide LiCoO2. The ternary composite positive electrode material precursor product is made of nickel salt, cobalt salt and manganese salt as raw materials. The ratio of nickel, cobalt and manganese can be adjusted according to actual needs.

[0003] Reference is made to a Chinese invention patent, publication number: CN 118976441 A, titled: A ternary precursor washing and dehydration reuse system, comprising a production mechanism and a reuse mechanism, wherein the production mechanism comprises a reactor, an aging tank, a washing device, a slurrying tank, a dehydration device, and a drying device; the reuse mechanism comprises a solid-liquid separator, a liquid storage tank, and a reuse pump, wherein 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 and dehydration reuse system provided by the invention is that the washing water and dehydration water generated during the washing and dehydration process are passed 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 passed into the aging tank, the water obtained from the solid-liquid separation enters the liquid storage tank, and is then pumped into the reactor by the reuse pump as reaction water. The present invention realizes the recycling and reuse of the ternary precursor washing and dehydration water, reduces the amount of production wastewater, reduces the amount of production pure water used, and reduces production costs.

[0004] However, there are still some problems in actual use:

[0005] The ternary precursor slurry needs to be separated into solid and liquid by a centrifugal device. The centrifugal device discharges the liquid and solid from both ends, but the centrifugal device cannot completely dry out the moisture in the solid. During the discharge process, the fixed body will agglomerate or clog the inside of the slag discharge hole. Over time, the solids that clog the slag discharge hole will stick to each other and accumulate, affecting the subsequent solid-liquid separation efficiency. Secondly, after the equipment is used, there is still a certain amount of water vapor inside it. If it is not cleaned in time, the water vapor will adhere to the inside of the equipment, corrode its internal parts, and reduce the service life of the equipment. Secondly, when the solid is discharged, there is still moisture inside, causing the solids to stick to each other and eventually form agglomerates, making it difficult for the water to evaporate. Summary of the Invention

[0006] Technical problems solved

[0007] The purpose of the present invention is to make up for the problem that when the existing ternary precursor slurry is subjected to solid-liquid separation, the centrifugal equipment discharges the liquid and solid from both ends, but the centrifugal equipment cannot completely dry out the moisture in the solid. During the discharge process, the fixed body agglomerates or clogs the inside of the slag discharge hole. Over time, the solids that clog the slag discharge hole adhere to each other and accumulate, affecting the subsequent solid-liquid separation efficiency. Secondly, after the equipment is used, there is still a certain amount of water vapor inside it. If it is not cleaned in time, the water vapor adheres to the inside of the equipment, corrodes its internal parts, and reduces the service life of the equipment.

[0021] 1. The present invention controls the electric push rod to drive the connecting cover and the sealing ring to move toward the slag discharge cover, and the extension pipe and the connecting cover are stretched and extended until the connecting cover is completely moved to the outside of the slag discharge cover, and then the raised part of the track block slowly moves to the top of the limit ring.

Secondly, the lumps are broken up, which facilitates drying and ensures the uniformity of the ternary precursor material.

[0042] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the control mechanism 15 includes a control motor 1501, a driving rod 1502, a sprocket 1503, a chain 1504, a limiting bar 1505, a sleeve 1506 and a driving gear 1507.

The drive rod 1502 and the sleeve 1506 both extend through the cover 1 to the interior thereof, and the sleeve 1506 is slidably connected at the connection of the cover 1. The drive gear 1507 is respectively engaged with the two drive rings 1403 through the transmission teeth 19, and the outer side of the sleeve 1506 is fixedly connected to the outer side of the connecting cover 1401 through a connecting piece.

[0043] It slides toward one end of the drive rod 1502 through the sleeve 1506, and then the drive gear 1507 moves following one end of the sleeve 1506. Then the drive motor 10 is started to drive the drive rod 1502 through the sprocket 1503 and the chain 1504 at the same time, prompting the drive rod 1502 to drive the sleeve 1506 to rotate through the limit bar 1505, and the drive gear 1507 is driven to drive the drive ring 1403 to rotate through the transmission tooth 19, which is beneficial for the transmission structure to follow its trajectory and the normal starting mechanism to clean the equipment when the blockage removal mechanism 14 is displaced, and secondly to avoid obstruction of the operation of internal parts during the operation of the equipment.

[0044] like Figure 1 、 Figure 2 、 Figure 8 and Figure 9As shown, the drying discharge mechanism 17 includes a connecting funnel 1701, a driving shaft 1702, a servo motor 1703, an eccentric column 1704, a track cover 1705, a connecting frame 1706 and a vibration plate 1707. The driving shaft 1702 is laterally movably connected to the inside of the connecting funnel 1701, and one end of the driving shaft 1702 passes 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 driving shaft 1702, and the track cover 1705 is sleeved on the outside of the eccentric column 1704. The connecting frame 1706 is symmetrically fixedly connected to the outside of the track cover 1705. The vibration plate 1707 is provided with several pieces which are respectively fixedly connected to the outside of the connecting frame 1706. The drying discharge mechanism 17 also includes a heater 1708, an external pipe 1709 and an air supply trough 1710. One end of the external pipe 1709 is fixedly connected to the output end of the heater 1708, and the other end of the external pipe 1709 is forked and fixedly connected to the conveying port of the air supply trough 1710. The connecting funnel 1701 is fixedly connected to the bottom end of the slag discharge port 16, and connecting grooves 22 are provided on both sides of the interior of the connecting funnel 1701, and the air supply troughs 1710 are respectively fixedly connected to the outside of the connecting grooves 22. The heater 1708 is fixedly connected to the surface of the frame 2.

[0045] By starting the servo motor 1703, the drive shaft 1702 is driven to rotate, and at the same time, the eccentric column 1704 is driven through the track cover 1705 and the connecting frame 1706 to drive the vibration plate 1707 to vibrate up and down. When the solid falls from the connecting funnel 1701 to the opposite side of the vibration plate 1707, it is affected by the vibration and hits the vibration plate 1707. Then the heater 1708 is started to send hot air into the air supply slot 1710 through the external pipe 1709 until it is evenly blown into the interval of the vibration plate 1707, which is conducive to drying the discharged solid again to ensure that the liquid content is further reduced. Secondly, the lumps are broken up to facilitate drying while ensuring the uniformity of the ternary precursor material.

[0046] Working principle: After the ternary precursor slurry is separated from the fixed liquid by the push screw 8, the push screw 8 pushes the separated solid to move to the slag discharge cover 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, and at the same time the eccentric column 1704 is driven to drive the vibration plate 1707 to vibrate up and down through the track cover 1705 and the connecting frame 1706, and the solid is discharged from the connecting funnel 17 When 01 falls to the opposite side of the vibration plate 1707, it is affected by the vibration and hits the vibration plate 1707, and then the heater 1708 is started to send hot air into the air supply slot 1710 through the external pipe 1709 until it is evenly blown into the interval between the vibration plates 1707. The equipment is turned off, and the electric push rod 1402 is controlled to drive the connecting cover 1401 and the sealing ring 13 to move toward the slag discharge cover 11. The extension pipe 23 stretches and extends with the connecting cover 1401 until the connecting cover 1401 is completely moved to the outside of the slag discharge cover 11. During this process, the connecting cover 1401 pulls the sleeve 1506 to move along the same trajectory through the connecting frame 1706. At the same time, the sleeve 1506 slides toward one end of the driving rod 1502. Then, the driving gear 1507 moves along with the sleeve 1506. Then, the driving motor 10 is started to drive the driving rod 1502 through the sprocket 1503 and the chain 1504 at the same time, so that the driving rod 1502 drives the sleeve 1506 to rotate through the limit bar 1505. The driving gear 1507 is driven by the transmission gear 19. The dynamic driving ring 1403 rotates, and then the raised 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 insert tube 1405 along the socket 18 to insert into the inside of the slag discharge hole 12. At the same time, the telescopic tube 1407 is stretched and extended. Then the fan 20 is started to evenly disperse the wind force along the connecting tube 21, the extension tube 23, and the annular tube 1409 to the diversion tube 1408, and then blown out from the bottom of the insert tube 1405 along the telescopic tube (1407).
