Description

Technical Field

[0001] The present invention relates to the technical field of electrolyte recovery and regeneration, and particularly to a device for separating power battery electrolytes. Background Art

[0002] When recycling power batteries, they need to be crushed after discharging. The crushed power batteries mainly contain toxic volatile substances, metal sludge, shredded materials, electrolytes and other important substances. Among them, the toxic volatile substances spread in the air are likely to cause safety hazards and affect life safety. The metal sludge and electrolytes can be recycled and reused. In order to recover these important substances, workers usually put these substances into a centrifuge separator for multi-stage separation after crushing, and at the same time use a hot air blower to accelerate the volatilization speed of the volatile substances to achieve the purpose of effective separation.

[0003] Due to the shredded materials and metal sludge under the centrifugal action will adhere to the separation components to varying degrees, and in the prior art when separating electrolytes, it is not convenient to effectively scrape off the adhered shredded materials and metal sludge, resulting in insufficient and slow separation of electrolytes, leading to low separation efficiency, and the shredded materials are prone to accumulation. And in the prior art, it is difficult to stir the shredded materials during separation, resulting in incomplete volatilization of the volatile substances, thus leading to poor separation effect. Summary of the Invention

[0004] In order to overcome the above disadvantages, the present invention provides a device for separating power battery electrolytes, which can effectively scrape off the adhered shredded materials and metal sludge during separation, making the electrolyte separation more sufficient and rapid, and can continuously stir the shredded materials to make the volatile substances volatilize more thoroughly, thereby enhancing the separation effect.

[0005] The technical solution of the present invention is: A device for separating power battery electrolytes includes an outer frame, on which there are an installation plate, a first plug plate, an air valve, a liquid valve, a hot air blower, a housing and four legs. Inside the outer frame, a recovery frame is fixedly connected, and a second plug plate is plugged on one side of the recovery frame. Inside the outer frame, there is a separation component, and between the housing and the separation component, there are a driving mechanism and a pressing mechanism.

[0006] Further, the separation component includes a filter frame, which is rotatably connected to the recovery frame. The recovery frame is rotatably connected with a separation frame. Four vertical grooves are opened around the separation frame. The top of the separation frame is fixedly connected to the top of the filter frame. At the bottom of both the separation frame and the filter frame, there are four sliding cylinders. A sliding frame is slidably connected between two adjacent sliding cylinders. At both ends of the four sliding frames, there are return springs connected between the eight sliding cylinders. Between the tops of the four sliding frames, a blocking ring is fixedly connected.

[0007] Further, the driving mechanism includes a motor, which is installed inside the housing. The output shaft of the motor is rotatably connected to the outer frame and the housing. The bottom end of the output shaft of the motor is fixedly connected to a transmission shaft. Two threaded structures extend downward from the bottom of the transmission shaft. A transmission plate is sleeved between the two threaded structures of the transmission shaft. The outer side of the transmission plate is clamped to the bottom of the separation frame. Nuts are threadedly connected to both of the two threaded structures of the transmission shaft.

[0008] Further, the extrusion mechanism includes electric push rods. Two electric push rods are installed inside the housing. Sliders are installed at the bottom ends of the push rods of the two electric push rods. An extrusion plate is slidably connected between the four vertical grooves. A slide rail is installed on the extrusion plate. Both of the two sliders are slidably connected to the slide rail.

[0009] Further, a number of small holes are formed in both the separation frame and the extrusion plate.

[0010] Further, a scraping mechanism is further included. The scraping mechanism is used to scrape off the metal sludge adhering to the inner wall of the filter frame and the outer wall of the separation frame and push it into the recovery frame. The scraping mechanism is arranged on the extrusion plate and the separation frame. The scraping mechanism includes a scraping ring. The scraping ring is fixedly connected to the bottom of the extrusion plate. The outer side of the scraping ring contacts the inner wall of the filter frame. The inner side of the scraping ring contacts the outer wall of the separation frame. Four sliding grooves are formed in the scraping ring. A sliding ring is slidably connected between the four sliding grooves. An extrusion ring is fixedly connected to the bottom of the sliding ring. A friction assembly is arranged on the sliding ring and the separation frame.

[0011] Further, both sides of the upper and lower parts of the scraping ring are inclined plane structures.

[0012] Further, the friction assembly includes friction frames. Four friction frames are fixedly connected to the sliding ring. Four fixing strips are fixedly connected to the inner wall of the separation frame. The four fixing strips all pass through the bottom around the extrusion plate. Friction strips are arranged on the four fixing strips. The four friction strips respectively contact the four friction frames.

[0013] Further, both the friction frames and the friction strips are made of rubber.

[0014] Further, a stirring mechanism is further included. The stirring mechanism is used to stir the shredded materials to further accelerate the volatilization speed of the volatile substances. The stirring mechanism is arranged on the recovery frame and the transmission plate. The stirring mechanism includes arc-shaped clamping strips. Four arc-shaped clamping strips are inside the recovery frame. A toothed ring is slidably connected between the four arc-shaped clamping strips. Three rotating shafts are rotatably connected to the transmission plate. Stirring plates are fixedly connected to the three rotating shafts. Tooth columns are fixedly connected to the bottoms of the three rotating shafts. The three tooth columns are all meshed with the toothed ring.

[0015] The beneficial effects of the present invention are as follows: 1. The present invention uses a hot air blower to generate hot air to quickly volatilize the volatile substances and discharge them through the air valve, improving the separation efficiency and preventing potential safety hazards caused by the remaining volatile substances after separation. The motor drives the separation component to rotate, and the electrolyte, metal sludge, and scraps are fully separated by centrifugal force. The electric push rod drives the extrusion plate to push down the floating and attached scraps on the inner wall of the separation frame, and the electrolyte and metal sludge quickly pass through the small holes of the separation frame after passing through the small holes of the extrusion plate. In this way, the electrolyte and metal sludge are not easily blocked by the attached scraps when passing through the small holes of the separation frame, thus making the separation of the electrolyte and metal sludge more thorough and significantly enhancing the separation effect.

[0016] 2. The up and down movement of the extrusion plate drives the scraping mechanism (fixed strip and friction strip) to move up and down. The scraping ring moves up and down to scrape off the attached metal sludge, enabling the electrolyte to be quickly and fully separated from the metal sludge through the filter frame, thereby further improving the separation efficiency. When the scraping ring moves down, it forms a closed state with the sliding ring to push the metal sludge downward, and at the same time, it pushes the electrolyte back into the separation frame or separates it through the filter frame. The extrusion ring moves down to squeeze the blocking ring downward, and the metal sludge, along with part of the electrolyte, is discharged into the recovery frame through the gap between the blocking ring, the separation frame, and the filter frame. In this way, the metal sludge can be separated and recovered.

[0017] 3. The rotation of the transmission plate drives the rotating shaft, stirring plate, and tooth column to rotate together. The rotation of the tooth column drives the rotating shaft and stirring plate to rotate together through the gear ring. The self-rotation of the stirring plate continuously stirs the scraps, enabling the volatile substances contained in the scraps to volatilize more thoroughly, further enhancing the separation effect.

Detailed implementation manners

[0038] The following describes the implementation manners of the present invention with reference to the drawings.

[0039] Embodiment 1: A device for separating the electrolyte of a power battery, as Figures 1 - 18 shown, includes an outer frame 101. Four support legs 102 are evenly and spacedly welded to the outer bottom of the outer frame 101. A mounting plate 103 is clamped to the bottom of the outer frame 101. A first plug plate 104 is plugged on one side of the top of the outer frame 101. A recovery frame 105 is welded to the inner bottom of the outer frame 101. The recovery frame 105 is used to collect the metal sludge separated from the electrolyte. One side of the recovery frame 105 communicates with the outside of the outer frame 101. A second plug plate is plugged at the communicating part between the recovery frame 105 and the outside of the outer frame 101. An air valve 106 is provided on the other side of the top of the outer frame 101. The air valve 106 is used to collect the volatile substances in the electrolyte. A liquid valve 107 is provided on one side of the bottom of the outer frame 101. The liquid valve 107 is used to collect the electrolyte separated from the shredded materials. A hot air blower 108 is installed on one side of the outer frame 101. The hot air blower 108 communicates with the inside of the outer frame 101. The hot air blower 108 is used to apply hot air to the inside of the outer frame 101, thereby accelerating the volatilization speed of the volatile substances. A housing 109 is welded to the top of the outer frame 101. A separation assembly is provided inside the outer frame 101. The separation assembly is used to separate the electrolyte in the shredded materials and the metal sludge contained in the electrolyte. A driving mechanism and an extrusion mechanism are provided between the housing 109 and the separation assembly. The driving mechanism is used to drive the separation assembly, and the extrusion mechanism is used to extrude the shredded materials so that the electrolyte is quickly separated from the shredded materials.

[0040] The separation component includes a filter frame 21, which is rotatably connected to the recovery frame 105. The filter frame 21 is used to separate the metal sludge contained in the electrolyte. A separation frame 22 is rotatably connected to the recovery frame 105. The separation frame 22 is used to separate the electrolyte in the shredded materials. Four vertical grooves 221 are evenly spaced around the separation frame 22. The top of the separation frame 22 is bolted to the top of the filter frame 21. Four sliding cylinders 23 are evenly spaced and welded to the bottoms of both the separation frame 22 and the filter frame 21. A sliding bracket 24 is slidably connected between two adjacent sliding cylinders 23. Return springs 25 are connected between the two ends of the four sliding brackets 24 and the eight sliding cylinders 23 respectively. A blocking ring 26 is welded between the tops of the four sliding brackets 24. The blocking ring 26 is used to block most of the electrolyte from flowing into the recovery frame 105.

[0041] The driving mechanism includes a motor 31, which is installed in the housing 109. The output shaft of the motor 31 is rotatably connected to the outer frame 101 and the housing 109. The bottom end of the output shaft of the motor 31 is connected to a transmission shaft 32 through a coupling. The transmission shaft 32 is located inside the outer frame 101 and on the axis of the separation frame 22. Two threaded structures extend downward from the bottom of the transmission shaft 32. A transmission plate 33 is sleeved between the two threaded structures of the transmission shaft 32. The outer side of the transmission plate 33 is clamped to the bottom of the separation frame 22. Nuts 34 are threadedly connected to both of the two threaded structures of the transmission shaft 32. Both of the two nuts 34 are located below the transmission plate 33. The cooperation between the two threaded structures of the transmission shaft 32 and the two nuts 34 can fix the transmission plate 33 on the transmission shaft 32.

[0042] The extrusion mechanism includes electric push rods 41. Two electric push rods 41 are symmetrically installed in the housing 109 and on both sides of the motor 31. The bottom ends of the push rods of the two electric push rods 41 are both installed with sliders 42. An extrusion plate 43 is slidably connected between the four vertical grooves 221. A slide rail 44 is installed on the extrusion plate 43. Both of the two sliders 42 are slidably connected to the slide rail 44.

[0043] A number of small holes are opened on both the separation frame 22 and the extrusion plate 43 for separating the electrolyte in the shredded materials.

[0044] First, the staff opens the air valve 106 and closes the liquid valve 107. At the same time, the hot air blower 108 is started and the first plug plate 104 is opened. Immediately afterwards, the staff pours the crushed materials of the power battery and the electrolyte containing metal sludge into the separation frame 22 together, quickly plugs the first plug plate 104 back onto the outer frame 101. The hot air blower 108 will blow hot air into the outer frame 101, and the volatilized substances will be discharged through the air valve 106, thereby enabling the volatile substances to volatilize quickly and improving the separation efficiency. In this way, the staff can recover the volatile substances through the air valve 106, thereby preventing the existence of toxic volatile substances after the electrolyte separation and generating potential safety hazards. Subsequently, the staff starts the motor 31 and controls the push rod of the electric push rod 41 to extend downward. The output shaft of the motor 31 rotates and drives the transmission plate 33 and the separation component to rotate together through the transmission shaft 32 and the nut 34. Under the action of centrifugal force, the crushed materials will be blocked within the separation frame 22, and the metal sludge will pass through the small holes of the separation frame 22 and be blocked between the filter frame 21 and the separation frame 22. At the same time, the electrolyte will sequentially pass through the small holes of the separation frame 22 and the filter frame 21 and be thrown onto the inner wall of the outer frame 101 and fall into the inner bottom of the outer frame 101. In this way, the electrolyte can be fully separated by centrifugal force; during the separation process, the separation frame 22 rotates to drive the extrusion plate 43 and the slide rail 44 to rotate on the slider 42. The push rod of the electric push rod 41 extends downward to drive the slider 42, the extrusion plate 43 and the slide rail 44 to move downward along the vertical groove 221 together. The downward movement of the extrusion plate 43 will push the floating and adhered crushed materials on the inner wall of the separation frame 22 downward together. The electrolyte and the metal sludge will quickly pass through the small holes of the separation frame 22 after passing through the small holes of the extrusion plate 43. In this way, the electrolyte and the metal sludge are not easily blocked by the adhered crushed materials when passing through the small holes of the separation frame 22, thereby enabling the electrolyte and the metal sludge to be separated more fully and quickly, significantly enhancing the separation effect. After the separation is completed, the staff closes the motor 31, the hot air blower 108 and the air valve 106, and at the same time controls the push rod of the electric push rod 41 to retract upward to drive the extrusion mechanism (except the electric push rod 41) to reset upward. Subsequently, the liquid valve 107 is opened, and the separated electrolyte will be discharged from the outer frame 101 through the liquid valve 107. After the staff recovers the electrolyte through the liquid valve 107, the liquid valve 107 is closed; when it is necessary to take out the separated crushed materials, the staff opens the mounting plate 103. Subsequently, the staff unscrews the two nuts 34. Immediately afterwards, the staff takes out the transmission plate 33 from the two threaded structures of the transmission shaft 32 and the separation frame 22 outside the outer frame 101. The separated crushed materials will be outside the outer frame 101 together with the transmission plate 33. Then the staff snaps the transmission plate 33 back onto the separation frame 22 and slips it back onto the two threaded structures of the transmission shaft 32, and screws the two nuts 34 back onto the two threaded structures of the transmission shaft 32. Finally, the staff installs the mounting plate 103 back onto the outer frame 101.

[0045] Example 2: On the basis of Example 1, asFigure 3 and Figures 12 - 16 As shown in Figures 12 - 16 , it further includes a scraping mechanism. The scraping mechanism is used to scrape off the metal sludge adhering to the inner wall of the filter frame 21 and the outer wall of the separation frame 22 and push it into the recovery frame 105. The scraping mechanism is arranged on the pressing plate 43 and the separation frame 22. The scraping mechanism includes a scraping ring 51. The scraping ring 51 is welded to the bottom of the pressing plate 43. The scraping ring 51 is located between the separation frame 22 and the filter frame 21. The outer side of the scraping ring 51 is in contact with the inner wall of the filter frame 21, and the inner side of the scraping ring 51 is in contact with the outer wall of the separation frame 22. The scraping ring 51 is used to scrape off the adhering metal sludge. Four sliding grooves are evenly spaced on the scraping ring 51. A sliding ring 52 is slidably connected between the four sliding grooves. A pressing ring 53 is welded to the bottom of the sliding ring 52. The pressing ring 53 is used to press the blocking ring 26. A friction assembly is arranged on the sliding ring 52 and the separation frame 22.

[0046] Both the upper and lower sides of the scraping ring 51 are inclined plane structures, which can scrape off the metal sludge more effectively.

[0047] The friction assembly includes friction frames 541. The four friction frames 541 are evenly spaced and connected to the sliding ring 52 by bolts. Four fixing bars 542 are evenly spaced and welded on the inner wall of the separation frame 22. The four fixing bars 542 all pass through the bottom around the pressing plate 43. Friction strips 543 are arranged on the sides of the four fixing bars 542 away from each other. The four friction strips 543 are respectively in contact with the four friction frames 541.

[0048] Both the friction frames 541 and the friction strips 543 are made of rubber. The frictional force between the friction frames 541 and the friction strips 543 can lift the sliding ring 52 and the pressing ring 53.

[0049] During separation, the up-and-down movement of the extrusion plate 43 drives the scraping mechanism (the fixed strip 542 and the friction strip 543) to move up and down. When the scraping ring 51 moves up and down, it will scrape off the metal sludge attached to the outer wall of the separation frame 22 and the inner wall of the filter frame 21, enabling the electrolyte to be quickly and fully separated from the metal sludge through the filter frame 21, thereby further improving the separation efficiency. While the scraping ring 51 moves downward, the frictional force between the friction strip 543 and the friction frame 541 causes the slip ring 52 and the extrusion ring 53 to remain stationary. Subsequently, the scraping ring 51 continues to move downward and drives the slip ring 52, the extrusion ring 53, and the friction frame 541 to move downward together through the chute. At this time, the slip ring 52 will form a seal with the scraping ring 51, making it difficult for the scraped metal sludge to pass through the scraping ring 51 when the scraping ring 51 moves downward. Subsequently, the scraping ring 51 moves upward, and the friction frame 541, the slip ring 52, and the extrusion ring 53 remain stationary. The scraping ring 51 continues to move upward and drives the friction frame 541, the slip ring 52, and the extrusion ring 53 to move upward together through the chute. At this time, the slip ring 52 and the scraping ring 51 are no longer sealed, allowing the scraped metal sludge to pass through the scraping ring 51 and reach the lower part when the scraping ring 51 moves upward. In this way, under the action of the frictional force between the friction frame 541 and the friction strip 543, the scraping ring 51 moves upward to scrape the metal sludge to the lower part. When the scraping ring 51 moves downward, it forms a seal with the slip ring 52 to scrape and push the metal sludge to the lower part, and at the same time, it will push the electrolyte back into the separation frame 22 or separate it through the filter frame 21. The scraped metal sludge will fall on the blocking ring 26. When the extrusion ring 53 moves downward to the bottom, the extrusion ring 53 will squeeze the blocking ring 26 and the sliding frame 24 to move downward together, and the return spring 25 is compressed. At this time, the metal sludge will be discharged into the recovery frame 105 through the gap between the blocking ring 26, the separation frame 22, and the filter frame 21 along with a part of the electrolyte. When the extrusion ring 53 moves upward and no longer squeezes the blocking ring 26, the return spring 25 resets and drives the sliding frame 24 and the blocking ring 26 to reset together, and the blocking ring 26 resets to re-form a seal with the separation frame 22 and the filter frame 21; after the separation is completed, the operator removes the second plug plate, and the metal sludge will be discharged from the bottom of the recovery frame 105 along with a small amount of electrolyte. After the operator recovers the metal sludge through the recovery frame 105, the second plug plate can be plugged back onto the recovery frame 105. In this way, the metal sludge can be separated and recovered.

[0050] Example 3: On the basis of Example 2, as Figure 3 and Figures 17 - 19As shown in the figure, it further includes a stirring mechanism for stirring the shredded material to further accelerate the volatilization rate of volatile substances. The stirring mechanism is arranged on the recovery frame 105 and the transmission plate 33. The stirring mechanism includes arc-shaped clamping strips 61. Four arc-shaped clamping strips 61 are welded to the inner side of the recovery frame 105 at uniform intervals. A gear ring 62 is slidably connected between the four arc-shaped clamping strips 61. The protruding direction of the arc-shaped clamping strips 61 is the same as the rotation direction of the output shaft of the motor 31, so that the gear ring 62 is not easily dropped during subsequent stirring. Three rotating shafts 63 are rotatably connected to the transmission plate 33 at uniform intervals. Stirring plates 64 are connected to the three rotating shafts 63 through key grooves. The stirring plates 64 are used to stir the shredded material. Tooth columns 65 are connected to the bottoms of the three rotating shafts 63 through key grooves. The three tooth columns 65 are all engaged with the gear ring 62.

[0051] The rotation of the transmission plate 33 drives the rotating shafts 63, the stirring plates 64 and the tooth columns 65 to rotate together. The rotation of the tooth columns 65 will drive the rotating shafts 63 and the stirring plates 64 to rotate together through the gear ring 62. The self-rotation of the stirring plates 64 will continuously stir the shredded material, so that the volatile substances contained in the shredded material can volatilize more thoroughly, further enhancing the separation effect. When taking out and putting back the transmission plate 33, the staff only needs to turn the gear ring 62 off and on the arc-shaped clamping rod before removing and after putting back the transmission plate 33. The rotating shafts 63, the stirring plates 64 and the tooth columns 65 will be removed together with the transmission plate 33.

Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
