Description

Technical Field

[0001] This application relates to the field of industrial equipment technology, and in particular to a sodium electrolytic material filter. Background Technology

[0002] Sodium-ion batteries are a core material for emerging high-energy-density batteries, primarily involving the insertion and separation of sodium ions between the positive and negative electrodes. These batteries require filters to remove impurities and particulate matter, which can adversely affect their performance and stability, such as clogging pipes, damaging equipment, or reducing product quality.

[0003] When sodium-ion battery materials flow through the filter in the slurry pipeline, the filter's larger volume reduces the material's flow velocity, potentially causing deposition. Over time, these deposits can form a jelly-like substance that can clog the filter pores, preventing sodium-ion battery materials from passing through and impacting production line operation and efficiency. Furthermore, incomplete filtration may leave residual jelly-like substances in the sodium-ion battery materials, affecting product purity and quality. Summary of the Invention

[0004] To reduce the deposition of sodium electrolytic materials in filters, this application provides a sodium electrolytic material filter.

[0005] The sodium electrolytic material filter provided in this application adopts the following technical solution:

[0006] A sodium-ion battery filter includes a filter cartridge, with an inlet at one end and an outlet at the top. The filter cartridge contains:

[0007] A filter assembly, comprising a first filter screen and a second filter screen disposed within a filter cylinder, wherein the first filter screen divides the filter cylinder into a first region and a second region, the inlet is located in the first region, the outlet is located in the second region, and the second filter screen covers the outlet.

[0008] A stirring assembly, comprising a cleaning cylinder rotatably disposed within a filter cylinder, wherein spiral stirring blades are provided on the outer peripheral wall of the cleaning cylinder;

[0009] A drive assembly, comprising a drive source disposed outside the filter cartridge, the drive source being used to drive the cleaning cartridge to rotate.

[0010] By adopting the above technical solution, the sodium-ion battery material enters the first region through the feed inlet. The first filter screen blocks impurities and particulate matter in the sodium-ion battery material in the first region. The filtered sodium-ion battery material enters the second region. The drive source drives the cleaning cylinder to rotate, causing the spiral stirring blades to agitate in the second region, thereby generating centrifugal force, increasing the flow rate of the sodium-ion battery material in the second region, reducing the possibility of the sodium-ion battery material forming a jelly-like substance due to deposition in the filter cylinder, and reducing the loss of sodium-ion battery material. The second filter screen can block the passage of jelly-like substances, reducing the amount of jelly-like substances that pass through the second filter screen and through the discharge port along with the sodium-ion battery material, improving the purity and quality of the sodium-ion battery material, and enhancing the filtration effect of the filter cylinder.

[0011] Preferably, the spiral stirring blades are provided with a number of filter holes.

[0012] By adopting the above technical solution, the filter holes on the spiral stirring blades allow nano-charged materials to pass through, while intercepting jelly-like substances, reducing the possibility of jelly-like substances moving to the surface of the second filter screen and clogging the outlet.

[0013] Preferably, one end of the cleaning cylinder is fixedly connected to a rotating rod, one end of which passes through the first filter screen and is located in the first area. The other end of the cleaning cylinder is fixedly connected to a driving rod, which extends out of the filter cylinder. The driving source can drive the driving rod to rotate and move laterally.

[0014] By adopting the above technical solution, the rotating rod and the driving rod provide support for the cleaning cylinder. When the driving source drives the driving rod to rotate and move laterally, the cleaning cylinder will rotate and move laterally together in the filter cylinder. When the spiral stirring blade moves towards the discharge port, the spiral stirring blade applies a thrust to the fluid in the second area, which further increases the flow rate of the nano-charged material moving towards the discharge port in the filter cylinder, and reduces the possibility of the nano-charged material depositing on the filter cylinder wall to form a jelly-like substance.

[0015] Preferably, a fixed bracket is fixedly connected to the outer end wall of the cleaning cylinder, and a fixed block that is threadedly connected to the drive rod is fixedly connected to the fixed bracket. A limiting edge is fixedly connected to the peripheral wall of the end of the drive rod away from the filter cylinder. The drive assembly includes a rotatable sleeve, and a limiting groove for the limiting edge to be inserted is opened on the inner wall of the sleeve. The drive source drives the sleeve to rotate.

[0016] By adopting the above technical solution, when the drive source drives the sleeve to rotate, the limiting edge is limited by the limiting groove wall, so that the drive rod rotates together with the sleeve. When the drive rod rotates, since the drive rod is threadedly connected to the fixed block and the fixed block is fixed on the fixed bracket, the drive rod can move and rotate laterally within the fixed block.

[0017] Preferably, a support block is fixedly connected to the outer wall of the fixed bracket, the sleeve is rotatably disposed inside the support block, the drive source is disposed on the support block, the drive end of the drive source is fixedly connected to a drive gear, and a drive gear meshing with the drive gear is fixedly connected to the sleeve.

[0018] By adopting the above technical solution, when the drive source drives the active gear to rotate, the active gear drives the drive gear to rotate together, and the drive gear drives the sleeve to rotate inside the support block, thereby causing the drive rod located inside the sleeve to rotate.

[0019] Preferably, the system also includes a cleaning component, which includes a plurality of suction nozzles spaced apart on the outer wall of the cleaning cylinder, the openings of the suction nozzles facing the inner wall of the cleaning cylinder, and the suction nozzles being connected to the cleaning cylinder; a third region is provided inside the filter cylinder, a partition plate is provided between the third region and the second region, one end of the cleaning cylinder passes through the partition plate and is located in the third region, and the end of the cleaning cylinder located in the third region is open.

[0020] By adopting the above technical solution, the suction nozzle can suck the jelly-like substance attached to the inner wall of the filter cartridge into the cleaning cartridge, and discharge it into the third area through the opening at the end of the cleaning cartridge. When the cleaning cartridge rotates and moves inside the filter cartridge, it drives the suction nozzle to move spirally inside the filter cartridge, thereby increasing the suction range of the suction nozzle on the inner wall of the cleaning cartridge and cleaning the inner wall of the cleaning cartridge.

[0021] Preferably, the filter cartridge is provided with a suction pipe that communicates with the third region.

[0022] By adopting the above technical solution, the suction pipe can recycle and reuse the jelly-like substance in the third area, thereby reducing the loss of the nanomaterial during the filtration process and improving economic efficiency.

[0023] Preferably, one end of the drive rod is inserted into the opening of the cleaning cylinder, and a positioning rod is fixedly connected between the inner walls of the cleaning cylinder, the positioning rod being perpendicularly connected to the end of the drive rod.

[0024] By adopting the above technical solution, the positioning rod is fixedly connected to the inner wall of the cleaning cylinder, and the end of the drive rod is fixedly connected to the positioning rod, so that the cleaning cylinder and the drive rod are fixedly connected. When the drive rod rotates and moves, it can drive the cleaning cylinder to rotate and move together, and at the same time, it can ensure that the jelly-like substance in the cleaning cylinder is discharged into the third area.

[0025] Preferably, the filter cylinder has a hole at the end away from the feed inlet for the drive rod to pass through, and a sealing ring that abuts against the outer peripheral wall of the drive rod is fixedly connected to the inner wall of the hole.

[0026] By adopting the above technical solution, when the drive rod moves back and forth in the hole, the sealing ring abuts against the outer wall of the drive rod, thereby reducing the liquid in the third area from flowing out of the hole and causing waste of sodium electrolytic material.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The sodium-ion battery material enters the first area through the feed inlet. The first filter screen blocks impurities and particulate matter in the sodium-ion battery material in the first area. The filtered sodium-ion battery material enters the second area. The drive source drives the cleaning cylinder to rotate, which causes the spiral stirring blades to stir in the second area, thereby generating centrifugal force, increasing the flow rate of the sodium-ion battery material in the second area, reducing the possibility of the sodium-ion battery material forming a jelly-like substance due to deposition in the filter cylinder, and reducing the loss of sodium-ion battery material. The second filter screen can block the passage of jelly-like substances, reducing the amount of jelly-like substances that pass through the second filter screen and through the discharge port along with the sodium-ion battery material, improving the purity and quality of the sodium-ion battery material, and enhancing the filtration effect of the filter cylinder.

[0029] 2. The filter holes on the spiral stirring blades allow nano-charged materials to pass through while intercepting jelly-like substances, reducing the possibility of jelly-like substances moving to the surface of the second filter screen and clogging the outlet.

[0030] 3. The rotating rod and drive rod provide support for the cleaning cylinder. When the drive source drives the drive rod to rotate and move laterally, the cleaning cylinder will rotate and move laterally together in the filter cylinder. When the spiral stirring blade moves towards the discharge port, the spiral stirring blade applies a thrust to the fluid in the second area, which further increases the flow rate of the nano-charged material moving towards the discharge port in the filter cylinder, and reduces the possibility of the nano-charged material depositing on the filter cylinder wall to form a jelly-like substance.

[0031] 4. The suction nozzle can suck the jelly-like substance adhering to the inner wall of the filter cartridge into the cleaning cartridge, and discharge it into the third area through the opening at the end of the cleaning cartridge. When the cleaning cartridge rotates and moves inside the filter cartridge, it drives the suction nozzle to move spirally inside the filter cartridge, thereby increasing the suction range of the suction nozzle on the inner wall of the cleaning cartridge and cleaning the inner wall of the cleaning cartridge.

[0038] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0039] This application discloses a sodium electrochemical material filter.

[0040] A sodium-ion filter, reference Figure 1 and Figure 2 The filter cylinder 1 includes a feed inlet 11 at one end and a discharge outlet 13. A feed pipe 12 connected to the feed inlet 11 is provided on the filter cylinder 1, and a discharge pipe 14 connected to the discharge outlet 13 is also provided on the filter cylinder 1.

[0041] Reference Figure 2 The filter cylinder 1 is equipped with a filter assembly 2, which includes a first filter screen 21 disposed in the filter cylinder 1. The outer peripheral wall of the first filter screen 21 is fixedly connected to the inner peripheral wall of the filter cylinder 1. The filter assembly 2 also includes a second filter screen 22, which is disposed at the discharge port 13 and covers the discharge port 13. A partition plate 51 is also disposed inside the filter cylinder 1. The partition plate 51 is disposed at the end of the first filter screen 21 away from the feed port 11. The first filter screen 21 and the partition plate 51 divide the filter cylinder 1 into a first region 15, a second region 16, and a third region 17. The feed port 11 is disposed in the first region 15, and the discharge port 13 is disposed in the second region 16.

[0042] Reference Figure 2The sodium-ionized material is conveyed to the first region 15 inside the filter cylinder 1 through the feed pipe 12. When the sodium-ionized material passes through the first filter screen 21, impurities in the sodium-ionized material are intercepted by the first filter screen 21 and thus accumulate in the first region 15. When the sodium-ionized material flows in the second region 16, since the volume of the filter cylinder 1 is larger than that of the feed pipe 12, the flow rate of the sodium-ionized material in the second region 16 decreases. The sodium-ionized material is deposited in the second region 16 and forms a jelly-like substance. The second filter screen 22 can block the jelly-like substance, keeping it in the second region 16. This reduces the amount of jelly-like substance that follows the sodium-ionized material through the second filter screen 22 and into the discharge pipe 14, thereby improving the purity and quality of the sodium-ionized material and enhancing the filtration effect of the filter cylinder 1.

[0043] Reference Figure 2 The filter cartridge 1 is also equipped with a cleaning component 5, which includes a cleaning cartridge 31 disposed in the second region 16. A plurality of suction nozzles 52 are spaced apart on the outer peripheral wall of the cleaning cartridge 31, facing the inner peripheral wall of the filter cartridge 1. The suction nozzles 52 communicate with the inner cavity of the cleaning cartridge 31. One end of the cleaning cartridge 31 near the first filter screen 21 is closed and fixedly connected to a rotating rod 42, which penetrates the first filter screen 21 and is inserted into the first region 15. The other end of the cleaning cartridge 31 penetrates the partition plate 51 and is inserted into the third region 17. The end of the cleaning cartridge 31 in the third region 17 is open, and a suction pipe 53 is disposed on the wall of the filter cartridge 1 in the third region 17. When the suction pipe 53 provides suction to the third area 17, the suction is transmitted to the suction nozzle 52 through the cleaning cylinder 31. The suction nozzle 52 sucks the jelly-like substance attached to the inner peripheral wall of the filter cylinder 1 into the cleaning cylinder 31, and then into the third area 17 through the opening at the end of the cleaning cylinder 31. The suction pipe 53 recycles and reuses the jelly-like substance in the third area 17, thereby reducing the loss of the nanomaterial during the filtration process and improving economic efficiency.

[0044] Reference Figure 2 and Figure 3 To improve the adsorption range of the suction nozzle 52 on the inner wall of the cleaning cylinder 31, a drive assembly 4 is also provided outside the filter cylinder 1 to drive the cleaning cylinder 31 to rotate and move within the second region 16. The drive assembly 4 includes a drive rod 43 fixedly connected to the cleaning cylinder 31. One end of the drive rod 43 is inserted into the opening of the cleaning cylinder 31 in the third region 17. A positioning rod 44 is vertically and fixedly connected to the end of the drive rod 43. Both ends of the positioning rod 44 are fixedly connected to the inner wall of the cleaning cylinder 31. One end of the filter cylinder 1 has a hole 18 for the other end of the drive rod 43 to pass through. A sealing ring 19 is fixedly connected to the inner wall of the hole 18. When the drive rod 43 moves back and forth in the hole 18, the sealing ring 19 abuts against the outer wall of the drive rod 43, thereby reducing the amount of liquid flowing out of the third region 17 from the hole 18 and causing waste of sodium-ion materials.

[0045] Reference Figure 2 and Figure 4 A fixed bracket 6 is fixedly connected to the outer end wall of the cleaning cylinder 31, and a fixed block 61 is fixedly connected to the fixed bracket 6. A threaded section 431 is provided on the drive rod 43 located outside the filter cylinder 1. The drive rod 43 passes through the fixed block 61 and is threadedly connected to the fixed block 61. A limiting edge 432 is fixedly connected to the end of the drive rod 43 away from the third region 17. The limiting edge 432 is set along the length direction of the drive rod 43.

[0046] Reference Figure 4 and Figure 5 The drive assembly 4 also includes a drive source 41 that drives the drive rod 43 to rotate. The drive source 41 is a servo motor. A support block 62 is fixedly connected to the outer wall of the fixed bracket 6. A sleeve 45 is rotatably disposed inside the support block 62. A drive gear 47 is sleeved and fixedly connected to the sleeve 45. The drive source 41 is fixed to the support block 62. A drive gear 46 that meshes with the drive gear 47 is sleeved and fixedly connected to the drive end of the drive source 41. One end of the drive rod 43 protrudes from the fixed bracket 6. A limiting groove 451 for the insertion of the limiting edge 432 is opened inside the sleeve 45. The drive rod 43 passes through the support block 62 and is inserted into the sleeve 45.

[0047] When the drive source 41 drives the drive gear 46 to rotate, the drive gear 46 drives the drive gear 47 to rotate, thereby causing the sleeve 45 to rotate within the support block 62. The limiting edge 432 is limited by the wall of the limiting groove 451, causing the drive rod 43 to rotate with the sleeve 45. When the drive rod 43 rotates, since the drive rod 43 is threadedly connected to the fixed block 61 and the fixed block 61 is fixed on the fixed bracket 6, the drive rod 43 can reciprocate within the fixed block 61. The drive rod 43 drives the filter cylinder 1 to rotate and reciprocate within the second region 16, thereby causing the suction nozzle 52 to rotate and move within the second region 16, thus expanding the adsorption range of the suction nozzle 52. This cleans the jelly-like substance attached to the inner wall of the filter cylinder 1 in the second region 16, reducing the possibility of the jelly-like substance clogging the second filter screen 22, while increasing the collection amount of the jelly-like substance and reducing the loss of the nanomaterial.

[0048] Reference Figure 2 In order to reduce the amount of jelly-like substance accumulated in the filter cartridge 1, a stirring assembly 3 is provided inside the filter cartridge 1. The stirring assembly 3 includes a spiral stirring blade 32 fixedly connected to the outer wall of the cleaning cartridge 31. The spiral stirring blade 32 is arranged between adjacent suction nozzles 52. Several filter holes 321 for the passage of electrical materials are opened on the spiral stirring blade 32.

[0049] When the cleaning cylinder 31 rotates and moves within the second region 16, the spiral stirring blade 32 rotates along with it. The spiral stirring blade 32 generates centrifugal force during its rotation within the second region 16, thereby increasing the flow velocity of the nano-charged material within this region. As the spiral stirring blade 32 moves towards the third region 17, it exerts a thrust on the fluid within the second region 16, further increasing the flow velocity of the nano-charged material towards the discharge pipe 14 and reducing the possibility of the nano-charged material depositing on the wall of the filter cylinder 1 to form a jelly-like substance. Furthermore, the spiral stirring blade 32 allows the nano-charged material to pass through while intercepting the jelly-like substance, reducing the possibility of the jelly-like substance moving to the surface of the second filter screen 22 and clogging the discharge port 13.

[0050] The implementation principle of a sodium-ion material filter in this application embodiment is as follows: the drive source 41 drives the drive rod 43 to rotate, and the fixed block 61 is threadedly connected to the drive rod 43, so that the drive rod 43 moves laterally within the fixed block 61, thereby causing the cleaning cylinder 31 to rotate and move within the second region 16. When the cleaning cylinder 31 rotates, it drives the spiral stirring blade 32 to rotate and move within the second region 16, increasing the flow rate of the sodium-ion material within the second region 16. The spiral stirring blade 32 can also block jelly-like substances, reducing the possibility of the outlet 13 being blocked.

[0051] When the cleaning cylinder 31 rotates and moves within the second region 16, the suction nozzle 52 rotates and moves along with the cleaning cylinder 31, allowing the suction nozzle 52 to clean the jelly-like substance on the inner wall of the filter cylinder 1. After the jelly-like substance is sucked into the cleaning cylinder 31, it enters the third region 17 through the opening at the end of the cleaning cylinder 31. The suction pipe 53 recycles and reuses the jelly-like substance in the third region 17, thereby reducing the loss of the nanomaterial during the filtration process and improving economic efficiency.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
