Description

Technical Field

[0001] This utility model relates to the field of electrolyte production equipment, specifically a high-purity electrolyte continuous production equipment. Background Technology

[0002] Vacuum-liquid separators primarily utilize the principle of vacuum suction to allow the electrolyte of lithium batteries to pass through a filter medium under negative pressure, thereby achieving solid-liquid separation. The electrolyte is first introduced into the interior of the vacuum-liquid separator. Inside the separator, due to the vacuum, the gas and liquid in the electrolyte begin to separate. After the first separation, it undergoes a second separation through the gas-liquid separation filter element on the cover. At the bottom of the separator, unfiltered solid particles gradually settle down, forming sludge. This sludge can be periodically discharged through the sludge discharge port at the bottom of the separator, while the filtered electrolyte is discharged through the liquid outlet of the separator for subsequent processing or use.

[0003] However, electrolytes have a certain viscosity and contain a lot of foamy impurities floating on the surface, which are difficult to remove cleanly using the existing gas-liquid separation filter element on the top of the cover. Therefore, a high-purity electrolyte continuous production equipment is proposed to address the above problems. Utility Model Content

[0027] The positioning frame 3 includes: a groove 31 and a second positioning handle 32. The frame of the positioning frame 3 has multiple grooves 31. The inner wall of the groove 31 is rotatably connected to the end of the elastic lever 4. Multiple second positioning handles 32 are fixedly connected to the upper part of the rod of the positioning frame 3. The end of the second positioning handle 32 is rotatably connected to the upper part of the elastic lever 4.

[0028] The elastic lever 4 includes: a fixed handle 41 and an elastic cylinder 42. The upper part of the elastic lever 4 is fixedly connected to one end of the fixed handle 41, the other end of the fixed handle 41 is rotatably connected to one end of the elastic cylinder 42, and the other end of the elastic cylinder 42 is rotatably connected to the end of the positioning handle 32.

[0029] The elastic cylinder 42 further includes: a retractable rod 421 and a spring 422. The inner wall of the elastic cylinder 42 is slidably connected to one end of the retractable rod 421, and the other end of the retractable rod 421 is rotatably connected to the end of the fixed handle 41.

[0030] The shaving component 5 includes: a positioning handle 51 and a plug-in block 52. The end of the shaving component 5 is fixedly connected to the end of the positioning handle 51.

[0032] Working principle: After the electrolyte to be separated enters the vacuum air-liquid separator 1 through the inlet 11, the gas and liquid in the electrolyte begin to separate. After the first separation, it undergoes a second separation through the gas-liquid separation filter element 21 on the cover 2. At this time, foam impurities will float on the surface of the liquid. Then, the handle at the end of the conical tooth column 23 is rotated, causing the conical tooth column 23 to drive the conical tooth column 1 22 to rotate clockwise. This causes the conical tooth column 1 22 to drive the positioning frame 3 to rotate synchronously. At this time, the positioning frame 3 drives the elastic lever 4 to rotate synchronously. The elastic lever 4 drives the foam scraper 5 to rotate synchronously. During the rotation of the foam scraper 5, it will push and accumulate the foam floating on the surface of the liquid. The accumulated foam will rotate with the foam scraper 5. When the foam scraper 5 moves to the position of the foam inlet 6, the stretched spring 1 422 will release the elastic force, causing the 5-conical tooth column-22 to pull the end of the retracting rod 421, thereby causing part of the retracting rod 421 to retract into the elastic cylinder 42. At the same time, the retracting rod 421 pulls the frame of the elastic lever 4 to rotate through the fixed handle-41, so that the foam scraper 5 can rotate upward in sync, causing the accumulated foam impurities to be pushed into the foam inlet 6, and then into the gas-liquid separation filter element 21 for collection. By using the positioning frame 3 to drive the foam scraper 5 through the elastic lever 4, the foam on the top of the liquid is pushed into the gas-liquid separation filter element 21 for collection, thereby completing the collection of foam impurities on the top of the electrolyte. Through the square through hole opened in the positioning handle 51, the insertion block 52 and the insertion post 72 are connected to fix the positioning handle 51, so that the foam scraper 5 can be quickly replaced after long-term use and wear.
