Description

Technical Field

[0001] The present invention relates to the technical field of ternary precursor powder washing, and specifically to a ternary precursor powder washing device. Background Art

[0002] Ternary precursor powder is a composite hydroxide composed of three metal elements of nickel (Ni), cobalt (Co), and manganese (Mn), and is usually used for the preparation of the cathode material of lithium-ion batteries. It is synthesized by the co-precipitation method, and its performance directly affects the energy density, cycle life, and safety of the final lithium battery. During the synthesis process of the ternary precursor, some residual impurities will be introduced. If not washed sufficiently, it will have a negative impact on the quality of the subsequent cathode material and the battery performance. Therefore, it is necessary to remove these impurities through multiple washes to ensure the high purity and uniformity of the powder, and then improve the electrochemical performance of the cathode material.

[0003] During the washing process of the ternary precursor, deionized water or ultrapure water is a commonly used washing medium to ensure the removal effect of impurity ions and prevent secondary pollution. The number of washes depends on the impurity content of the precursor powder and the quality requirements of the final material. Usually, 3 to 5 washes are required to ensure that the impurity concentration is reduced to the qualified range. Currently, the ternary precursor powder is usually washed in a vertically placed cylinder, and each time the water is changed, the washing liquid in the cylinder is discharged through the discharge pipe.

[0004] However, there are some problems with this washing method:

[0005] Long drainage time: Due to simple gravity drainage, it takes a long time for the washing liquid to be completely discharged.

[0006] Incomplete drainage: Some washing liquid will still remain between the powders, affecting the thoroughness of washing and making it difficult to completely remove impurities.

[0007] Affecting the washing effect: The remaining washing liquid will also affect the water quality during the subsequent washing process, reducing the washing effect, while increasing the water consumption and washing time. Summary of the Invention

[0008] The present invention provides a ternary precursor powder washing device, which solves the technical problems existing in the current washing method of ternary precursor powder, such as long drainage time, incomplete drainage, and at the same time, some washing liquid remains between the powders, affecting the removal of impurities, and the residual liquid will also contaminate the subsequent washing water, reducing the washing effect, and increasing water consumption and washing time.

[0009] A ternary precursor powder washing device provided by the present invention includes a processing table, two symmetrically arranged supports slidably disposed on the processing table, and two symmetrically arranged mounting support plates fixedly connected to the upper end surface of the processing table. Both upper parts of the two supports are fixedly connected with mating semi-cylinders. The opposite side walls of the two mating semi-cylinders are both slidably connected with filter mesh cylinders through first spring telescopic rods. The two filter mesh cylinders are used to be butted against each other for placing ternary precursor powder. The two butted semi-cylinders are used to be butted against each other and sleeved outside the filter mesh cylinder for introducing washing liquid for washing. A mutual driving part is jointly arranged between the two mounting support plates and the supports for driving the mating semi-cylinders to move towards each other quickly for butting for washing or quickly separating to discharge the washing wastewater for water replacement. A pushing mechanism is jointly arranged between the mounting support plate, the mating semi-cylinder and the filter mesh cylinder on the same side and is in linkage cooperation with the mutual driving part for extruding the washing liquid in the ternary precursor powder by squeezing the ternary precursor powder in the filter mesh cylinder when the mating semi-cylinder separates. A stirring mechanism is jointly arranged between the mounting support plate and the filter mesh cylinder on the same side for stirring the ternary precursor powder during washing to accelerate the washing speed. A feeding part is jointly arranged between the left mating semi-cylinder and the filter mesh cylinder.

[0010] In a possible implementation manner, the mutual driving part includes a bidirectional screw rotatably connected between the two mounting support plates and passing through the two supports. The supports are in threaded connection with the bidirectional screw. A first driving motor is embedded and installed on the right mounting support plate, and the output shaft of the first driving motor is fixedly connected to the bidirectional screw.

[0011] In a possible implementation manner, the stirring mechanism includes a rotating shaft rotatably connected through the center of the side wall plate of the end of the filter mesh cylinder, and the rotating shaft penetrates and slides on the side wall plate of the end of the mating semi-cylinder. A plurality of strip-shaped seats are circumferentially and equidistantly fixedly connected to the outer wall of the rotating shaft and located in the inner cavity of the filter mesh cylinder. A plurality of stirring blades are equidistantly fixedly connected to one side of the strip-shaped seat away from the mounting support plate. A driving assembly for driving the rotating shaft to rotate is arranged on the mounting support plate.

[0012] In a possible implementation manner, the driving assembly includes a second driving motor embedded and installed on the mounting support plate. The output shaft of the second driving motor is fixedly connected with a shaft cylinder. The shaft cylinder is slidably sleeved outside the rotating shaft. A positioning groove is axially opened on the outside of the rotating shaft, and a positioning strip slidably connected in the positioning groove is fixedly connected to the inner cavity of the shaft cylinder.

[0013] In a possible implementation, the pushing mechanism includes a push plate slidably connected in the filter screen cylinder, and the push plate is slidably sleeved outside the stirring blade. One side of the push plate close to the mounting support plate is fixedly connected with an annular connector through a connecting column. A second spring telescopic rod is slidably connected through the side wall plate of the end of the mating semi-cylinder body. One end of the second spring telescopic rod located inside the mating semi-cylinder body is fixedly connected with an arc-shaped clamping sleeve slidably sleeved outside the annular connector. A linkage assembly is jointly arranged between the second spring telescopic rod and the bidirectional screw.

[0014] In a possible implementation, the linkage assembly includes a threaded rod slidably connected through the mounting support plate, and the proximal end of the threaded rod close to the second spring telescopic rod is fixedly connected to each other. One side of the mounting support plate close to the mating semi-cylinder body is rotatably connected with a threaded ring, and the threaded ring is threadedly connected to the threaded rod. A belt pulley is fixedly connected to the outside of the bidirectional screw, and a transmission belt is jointly connected between the belt pulley and the threaded ring for transmission.

[0015] In a possible implementation, a limiting groove is axially formed on the outer wall of the threaded rod, and a limiting strip slidably arranged in the limiting groove is fixedly connected to the mounting support plate. The thread grooves on the left and right threaded rods have opposite helix directions.

[0016] In a possible implementation, the feeding part is composed of an input pipe communicated with the mating semi-cylinder body and a corrugated telescopic pipe jointly communicated between the lower end of the input pipe and the filter screen cylinder.

[0017] In a possible implementation, a plurality of strip-shaped through grooves are circumferentially and equally spaced on the opposite sides of the two filter screen cylinders, and the horizontally opposite strip-shaped through grooves are staggeredly distributed. The strip-shaped section on one filter screen cylinder corresponds to the horizontal position of the strip-shaped through groove on the other filter screen cylinder.

[0018] In a possible implementation, the outer wall of the mating semi-cylinder body located on the left is fixedly connected with an annular sleeve with an opening on the right, and the outer wall of the mating semi-cylinder body located on the right is fixedly connected with an annular ring matched with the annular sleeve. Both the annular ring and the annular sleeve are made of elastic rubber.

[0019] From the above technical solutions, it can be seen that the present invention has the following advantages:

[0020] In the present invention, the two mating semi-cylinder bodies are horizontally separated by the opposite driving part to form a large opening, so that the washing waste water can be discharged in large quantities instantaneously, greatly improving the drainage efficiency.

[0021] In the present invention, when the opposite driving part operates, it simultaneously touches the pushing mechanism to extrude the ternary precursor powder, forcing the residual liquid inside the powder to be discharged, effectively emptying the residual liquid, avoiding the pollution of the new water every time the water is changed, reducing the water consumption, and improving the utilization rate of the washing liquid.

[0022] In the present invention, compared with the traditional method, the washing method that combines rapid drainage and extrusion dehydration can greatly shorten the washing time, bringing faster washing efficiency, lower water consumption, and more thorough impurity removal, ultimately improving the washing quality of the ternary precursor powder.

[0023] In the present invention, the two filter drums are indirectly driven horizontally to separate by the opposite driving part, and then combined with the stirring mechanism, directly expanding the discharge port and being able to break the adhesion force between the powders, making the powders easier to disperse and pour out quickly in large quantities.

Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] Please refer to Figure 1 , Figure 2 and Figure 3, the present invention provides a technical solution: a ternary precursor powder washing device, including a processing table 1, two supports 2 slidably arranged symmetrically left and right on the processing table 1, and two installation support plates 3 fixedly connected to the upper end surface of the processing table 1 symmetrically left and right. A guiding groove is provided on the upper end surface of the processing table 1, and the two supports 2 are slidably arranged in the guiding groove. A pair of mating semi-cylinders 4 are fixedly connected to the upper parts of the two supports 2. The opposite side walls of the two mating semi-cylinders 4 are both slidably connected to a filter mesh cylinder 5 through a first spring telescopic rod 9. The two filter mesh cylinders 5 are used to be butt-jointed with each other for placing ternary precursor powder. The two butt-jointed semi-cylinders are used to be butt-jointed and sleeved outside the filter mesh cylinder 5 for introducing washing liquid for washing. A mutual driving part 6 is jointly arranged between the two installation support plates 3 and the supports 2 for driving the mating semi-cylinders 4 to move towards each other quickly for docking for washing or quickly separating to discharge the washing wastewater and change water. A pressing mechanism 7 is jointly arranged between the installation support plate 3, the mating semi-cylinder 4 and the filter mesh cylinder 5 on the same side, which is linked and cooperated with the mutual driving part 6 and is used to squeeze the ternary precursor powder in the filter mesh cylinder 5 when the mating semi-cylinder 4 separates to squeeze out the washing liquid in the ternary precursor powder. A stirring mechanism 8 is jointly arranged between the installation support plate 3 and the filter mesh cylinder 5 on the same side for stirring the ternary precursor powder during washing to accelerate the washing speed. A feeding part is jointly arranged between the mating semi-cylinder 4 and the filter mesh cylinder 5 on the left. The feeding part is composed of an input pipe 10 connected to the mating semi-cylinder 4 and a corrugated telescopic pipe 11 jointly connected between the lower end of the input pipe 10 and the filter mesh cylinder 5. An annular sleeve 12 with an opening on the right is fixedly connected to the outer wall of the mating semi-cylinder 4 on the left, and an annular ring matched with the annular sleeve 12 is fixedly connected to the outer wall of the mating semi-cylinder 4 on the right. Both the annular ring and the annular sleeve 12 are made of elastic rubber.

[0035] Please refer to Figure 3 , in this embodiment, a plurality of strip-shaped through grooves are circumferentially and equidistantly arranged on the opposite sides of the two filter mesh cylinders 5, and the horizontally opposite strip-shaped through grooves are staggeredly distributed. The strip-shaped sections on one of the filter mesh cylinders 5 correspond to the horizontal positions of the strip-shaped through grooves on the other filter mesh cylinder 5.

[0036] Please refer to Figure 1 and Figure 2 , the mutual driving part 6 includes a bidirectional screw 61 rotatably connected between the two installation support plates 3 and passing through the two supports 2. The supports 2 are threadedly connected to the bidirectional screw 61. A first driving motor 62 is embedded and installed on the installation support plate 3 on the right, and the output shaft of the first driving motor 62 is fixedly connected to the bidirectional screw 61.

[0037] Please refer to Figure 3 and Figure 6, the stirring mechanism 8 includes a rotating shaft 81 that is rotatably connected through the center of the side wall plate at the end of the filter mesh cylinder 5, and the rotating shaft 81 passes through and slides on the side wall plate of the butting semi-cylinder 4. A number of strip-shaped seats 82 are circumferentially and equidistantly fixedly connected to the outer wall of the rotating shaft 81 and located in the inner cavity of the filter mesh cylinder 5. A number of stirring blades 83 are equidistantly fixedly connected to the side of the strip-shaped seat 82 away from the mounting support plate 3. A driving component 84 for driving the rotating shaft 81 to rotate is provided on the mounting support plate 3. The driving component 84 includes a second driving motor 841 embedded and installed on the mounting support plate 3. The output shaft of the second driving motor 841 is fixedly connected with a shaft cylinder 842. The shaft cylinder 842 is slidably sleeved outside the rotating shaft 81. A positioning groove is axially opened on the outside of the rotating shaft 81, and a positioning strip slidably connected in the positioning groove is fixedly connected to the inner cavity of the shaft cylinder 842.

[0038] First, prepare for washing: control the operation of the first driving motor 62 to drive the bidirectional screw 61 to rotate. The bidirectional screw 61 then drives the two supports 2 to move closer to each other. The supports 2 then drive the butting semi-cylinder 4 to move. The butting semi-cylinder 4 then drives the filter mesh cylinder 5 to move synchronously through the first spring telescopic rod 9. The distance between the two filter mesh cylinders 5 is smaller than the distance between the two butting semi-cylinders 4, so that the two filter mesh cylinders 5 will first butt against each other. Then the two butting semi-cylinders 4 continue to move closer to each other, pressing the first spring telescopic rod 9 to contract. At this time, a dislocation movement occurs between the butting semi-cylinder 4 and the filter mesh cylinder 5, thereby driving the corrugated telescopic tube 11 to be stretched until the two butting semi-cylinders 4 butt against each other. At the same time, the annular ring will also be inserted into the annular sleeve 12 to enhance the sealing strength between the two butting semi-cylinders 4.

[0039] The transverse movement of the filter mesh cylinder 5 drives the rotating shaft 81 to move transversely synchronously. The rotating shaft 81 then slides in the shaft cylinder 842.

[0040] Then, first, the ternary precursor powder (hereinafter referred to as powder) is introduced into the input pipe 10. Then, the powder enters the area between the two filter mesh cylinders 5 through the corrugated telescopic pipe 11. After introducing a specified amount of powder, the washing liquid is then introduced into the input pipe 10. Subsequently, the washing liquid enters the mating half-cylinder body 4 through the corrugated telescopic pipe 11 until the space between the two mating half-cylinder bodies 4 is filled. Then, the driving motor two 841 is controlled to operate to drive the shaft cylinder 842 to rotate. The shaft cylinder 842 then drives the rotating shaft 81 to rotate. The rotating shaft 81 then drives the stirring blades 83 to rotate through the strip-shaped seat 82, stirring the powder to move in the washing liquid to wash the powder. After washing for a certain period of time, the driving motor one 62 is controlled to drive the bidirectional screw 61 to rotate in the reverse direction. The bidirectional screw 61 then drives the two supports 2 to move away from each other. The supports 2 then drive the mating half-cylinder bodies 4 to move away from each other and separate. After the two mating half-cylinder bodies 4 are separated by a certain distance, the driving motor one 62 is controlled to pause. At this time, under the pushing of the first spring telescopic rod 9, the two filter mesh cylinders 5 are still in a butted state. After the two mating half-cylinder bodies 4 are separated, the washed wastewater can be discharged in a large amount instantaneously. An external collection box can be placed between the two mating half-cylinder bodies 4 in advance to catch the wastewater.

[0041] During the process that the bidirectional screw 61 rotates in the reverse direction to drive the two mating half-cylinder bodies 4 to move away from each other, the pushing mechanism 7 is triggered to operate, squeezing the powder in the filter mesh cylinder 5 to squeeze out the washing liquid in the powder, increasing the drainage volume of the washing liquid and reducing the residual liquid. Immediately afterwards, the driving motor one 62 is driven again to drive the bidirectional screw 61 to rotate, indirectly driving the two mating half-cylinder bodies 4 to move closer to each other until they are butted again. Then, the above steps are repeated again. The washing liquid is introduced into the mating half-cylinder body 4 through the input pipe 10 to wash the powder for the second time. After the second washing, the above operations of draining water and then introducing water can be repeated again until the powder is finally washed.

[0042] When the final washing of the powder is completed, the bidirectional screw 61 is driven to reverse by the driving motor 62. The bidirectional screw 61 then drives the two mating half cylinders 4 to move away from each other through the support 2. At the same time, the pressing mechanism 7 is triggered to extrude the powder for further drainage. After the liquid in the powder is discharged, the driving motor 62 is controlled to pause. At this time, the two filter drums 5 are still in the butted state. At the same time, the collection box for collecting the slow liquid is removed, and another collection box is moved to directly below the two filter drums. Subsequently, the driving motor 62 is controlled to start, and then indirectly drives the two mating half cylinders 4 to continue moving away. The mating half cylinders 4 then drive the filter drum 5 to move through the spring telescopic rod 9, so that the two filter drums 5 move away from each other. A gap appears between the long strip section of the filter drum 5 and the strip-shaped through groove of the other filter drum 5. The washed powder then falls out from the strip-shaped through groove and into the collection box located directly below at this time. At the same time, the rotating shaft 81 is also in a rotating state. The rotating shaft 81 drives the stirring blade 83 to rotate through the strip-shaped seat 82, stirs the powder, and accelerates the discharge speed of the washed powder.

[0043] Please refer to Figure 3 and Figure 4 In this embodiment, the pressing mechanism 7 includes a push plate 71 slidably connected in the filter drum 5, and the push plate 71 is slidably sleeved outside the stirring blade 83. One side of the push plate 71 close to the mounting support plate 3 is fixedly connected with an annular connector 72 through a connecting column. A spring telescopic rod 73 is slidably connected through the end side wall plate of the mating half cylinder 4. The end of the spring telescopic rod 73 located in the inner cavity of the mating half cylinder 4 is fixedly connected with an arc-shaped clamping sleeve 74 slidably sleeved outside the annular connector 72. A linkage assembly 75 is jointly provided between the spring telescopic rod 73 and the bidirectional screw 61.

[0044] Please refer to Figure 3 and Figure 5 The linkage assembly 75 includes a threaded rod 751 slidably connected through the mounting support plate 3, and the proximal end of the threaded rod 751 close to the spring telescopic rod 73 is fixedly connected to each other. A threaded ring 752 is rotatably connected to one side of the mounting support plate 3 close to the mating half cylinder 4, and the threaded ring 752 is threadedly connected to the threaded rod 751. A belt pulley is fixedly connected to the outside of the bidirectional screw 61, and a transmission belt 753 is jointly connected in transmission between the belt pulley and the threaded ring 752. A limiting groove 754 is opened along the axis on the outer wall of the threaded rod 751, and a limiting strip slidably arranged in the limiting groove 754 is fixedly connected to the mounting support plate 3. The limiting strip is embedded into the limiting groove 754 to limit the threaded rod 751, so that the threaded rod 751 can only move horizontally. The thread grooves on the left and right threaded rods 751 have opposite helix directions.

[0045] When the two-way screw 61 rotates in reverse to indirectly drive the two mating half cylinders 4 to move away from each other, it will also drive the pulley to rotate synchronously. The pulley then drives the threaded ring 752 to rotate through the transmission belt 753. During the rotation of the threaded ring 752, it drives the threaded rod 751 to move horizontally towards the filter screen cylinder 5. Since the thread grooves on the two threaded rods 751 have opposite helix directions, the two threaded rods 751 will move towards each other. Therefore, at this time, the two threaded rods 751 move closer to each other. The threaded rod 751 then moves the annular connector 72 by means of the second spring telescopic rod 73 and the arc-shaped clamping sleeve 74. The annular connector 72 then moves the push plate 71 by means of the connecting column. The two push plates 71 move closer to each other, so that the powder can be extruded during the drainage process when the two mating half cylinders 4 move away from each other, and the liquid in the powder can be squeezed out.

[0046] During the process of the two-way screw 61 rotating forward to drive the two mating half cylinders 4 to move closer to each other and dock, it will also drive the threaded ring 752 to rotate forward through the pulley and the transmission belt 753. The threaded ring 752 then drives the threaded rod 751 to move horizontally, causing the two threaded rings 752 to move away from each other. The threaded rod 751 then drives the push plate 71 to move away from each other through the second spring telescopic rod 73, the arc-shaped clamping sleeve 74, the annular connector 72 and the connecting column, so as to vacate the space of the filter screen cylinder 5 for subsequent stirring during powder washing.

[0047] When the stirring mechanism 8 is running, the strip seat 82 drives the stirring blade 83 to rotate. At the same time, the stirring blade 83 drives the push plate 71 to rotate synchronously. The push plate 71 then drives the annular connector 72 to rotate through the connecting column. The annular connector 72 then rotates in the arc-shaped clamping sleeve 74, thus avoiding the situation of motion interference between the stirring mechanism 8 and the pressing mechanism 7.

[0048] During operation, first control the operation of the opposite driving part 6. The opposite driving part 6 drives the two mating half cylinders 4 to move towards each other. Then, the mating half cylinders 4 drive the filter mesh cylinders 5 to move towards each other. The two filter mesh cylinders 5 are the first to be butted, and then the two mating half cylinders 4 are butted together. Then, successively introduce the ternary precursor powder and the washing liquid into the interior of the mating half cylinders 4. Specifically, the ternary precursor powder is introduced into the filter mesh cylinders 5. Then, control the operation of the stirring mechanism 8 to stir the ternary precursor powder and the washing liquid, thereby washing the ternary precursor powder. After a single washing, control the opposite driving part 6 to move in the reverse direction to drive the two mating half cylinders 4 to move away from each other by a certain distance. The filter mesh cylinders 5 remain in the butted state and pause. Quickly discharge the washing liquid. At the same time, when the opposite driving part 6 moves in the reverse direction, it triggers the operation of the pushing mechanism 7 to squeeze out the washing liquid in the ternary precursor powder. Subsequently, control the operation of the opposite driving part 6 again to drive the mating half cylinders 4 to return to the butted state, and new washing liquid can be introduced into the mating half cylinders 4 again for secondary washing. Repeat the above steps in a cycle to wash the ternary precursor powder multiple times until the overall washing operation is completed.
