Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid electrolyte recycling, specifically a device for testing or crushing and reusing retired power batteries. Background Technology
[0002] In the precise process of power battery manufacturing, collecting electrolyte from retired power batteries is particularly important, and electrolyte injection is a crucial step. After the injection operation, traces of electrolyte will inevitably remain in the injection cup or container. To ensure the accuracy of subsequent battery injection and avoid any minor errors, the recycling and treatment of these residual electrolytes is particularly necessary. It ensures the continuous efficiency of the production line and the excellent stability of product quality.
[0003] Chinese patent CN220934357U discloses an electrolyte recovery device, including a storage tank. An installation cylinder is fixedly connected to the top of the storage tank. A lifting control component is installed inside the installation cylinder. By opening a solenoid valve, the electrolyte inside the storage tank can be discharged. Then, the lifting control component controls the hanging ring to descend, so that the hanging ring slides down along the inner wall of the installation cylinder, scraping off the electrolyte droplets adhering to the inner wall of the storage tank. This allows the residual electrolyte to be discharged through the bottom of the storage tank, avoiding the residual droplets from affecting the subsequent battery filling accuracy.
[0004] The electrolyte recovery device described in the above patent requires gradual activation via a hanging ring and a liquid blowing assembly to complete the cleaning of the inner wall of the equipment, resulting in low cleaning efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a device for detecting or crushing and reusing retired power batteries. By rotating the threaded rod and one end of the second rotating shaft, the first scraping plate can be moved vertically downwards, causing it to adhere to the inner wall of the lower liquid collection tank. Subsequently, by rotating, the first scraping plate can be rotated around the inner wall of the lower liquid collection tank, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for testing or crushing and reusing retired power batteries, comprising a lower liquid receiving tank, an electromagnetic valve disposed at the middle position of the lower end of the lower liquid receiving tank, a liquid adding pipe disposed on one side of the outer wall of the lower liquid receiving tank, an upper storage tank disposed at the upper end of the interior of the lower liquid receiving tank and welded and fixed to the upper end of the lower liquid receiving tank, a transmission column disposed longitudinally inside the upper storage tank, a first scraping plate disposed on the other side of the transmission column, and an inclined second scraping plate disposed at the lower end of the first scraping plate.
[0007] Preferably, the second scraper plate and the first scraper plate are integral structures, and the inner side of the first scraper plate and the second scraper plate facing the lower liquid collection tank is provided with a material discharge chamber.
[0008] Preferably, three transmission rods are evenly distributed longitudinally between the first scraping plate and the transmission column.
[0009] Preferably, one end of the transmission rod is rotatably connected to one side of the first scraping plate via a first rotating shaft, and the other end of the transmission rod is rotatably connected to the interior of the transmission column via a second rotating shaft.
[0010] Preferably, a gear is provided at the upper end of the outer side of the upper storage tank, and a transmission block is provided at the upper end of the transmission column. The transmission block and the gear are welded and fixed together through the upper storage tank.
[0011] Preferably, the lower end of the transmission block is provided with a threaded rod, one end of which extends into the interior of the transmission column, and the outer side of the threaded rod engages with the internal thread of the transmission column.
[0012] Preferably, a sliding rod is provided on the other side of the threaded rod, and the upper end of the sliding rod is welded and fixed to the lower end of the transmission block.
[0013] Preferably, the lower end of the sliding rod is embedded inside the transmission column and slidably connected to the inside of the transmission column.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] The present invention features a motor suspended on the outer wall of the transmission column, which outputs power to the transmission rod, causing the transmission rod to rotate. This rotation moves the material discharge chamber and the inclined second scraper plate towards the inner wall of the lower liquid collection tank, bringing them into contact with the electrolyte. Finally, the gear, via the motor's output, drives the first and second scraper plates at the lower end to rotate, allowing them to directly scrape and remove the electrolyte remaining on the inner wall of the lower liquid collection tank. The scraped electrolyte flows into the material discharge chamber. As the first and second scraper plates rotate, the scraped electrolyte flows along the material discharge chamber and is discharged uniformly from the bottom of the lower liquid collection tank. The entire process of cleaning the inner wall of the lower liquid collection tank is highly efficient, requiring only the unfolding and rotation of the first scraper plate. This high efficiency reduces the structural requirements for cleaning the inner wall of the lower liquid collection tank, improves the stability of the equipment during operation, and reduces manufacturing costs.

Detailed Implementation
[0022] The present invention will be further described below with reference to specific embodiments.
[0023] Example 1
[0024] like Figure 1 As shown, a device for testing or crushing and reusing retired power batteries in this embodiment includes a lower liquid receiving tank 1. A solenoid valve 3 is provided at the middle position of the lower end of the lower liquid receiving tank 1, and the solenoid valve 3 is sealed to the lower end of the lower liquid receiving tank 1. The electrolyte that is transmitted and retained inside the lower liquid receiving tank 1 will be stored inside the lower liquid receiving tank 1 by being restricted by the solenoid valve 3. A liquid adding pipe 2 is provided on one side of the outer wall of the lower liquid receiving tank 1, and the liquid adding pipe 2 is sealed to the outer wall of the lower liquid receiving tank 1. The electrolyte is transmitted towards the interior of the lower liquid receiving tank 1 through the liquid adding pipe 2.
[0025] Among them, such as Figure 2 As shown, an upper storage tank 4 is provided at the upper end of the lower liquid receiving tank 1. A transmission column 7 is arranged longitudinally inside the upper storage tank 4. A first scraping plate 8 is provided on the other side of the transmission column 7. The horizontal position of the first scraping plate 8 and the scraping of the first scraping plate 8 against the inner wall of the lower liquid receiving tank 1 can be adjusted by the rotation and longitudinal movement of the transmission column 7.
[0026] To facilitate the storage of the first scraping plate 8 and prevent it from continuously unfolding and adhering to the inner wall of the lower liquid collection tank 1, such as... Figure 2 and Figure 4As shown, three transmission rods 11 are evenly distributed longitudinally between the first scraping plate 8 and the transmission column 7. One end of the transmission rod 11 is rotatably connected to one side of the first scraping plate 8 through a first rotating shaft 12, and the other end of the transmission rod 11 is rotatably connected to the inside of the transmission column 7 through a second rotating shaft 15. The connection between the first rotating shaft 12 and the second rotating shaft 15 facilitates the transmission of the first scraping plate 8, which is convenient for the output to make the first scraping plate 8 rotate and scrape the inner wall of the liquid collection tank 1. Similarly, after the transmission rod 11 is rotated counterclockwise by the motor, it can pull the first scraping plate 8 closer to the transmission column 7 to complete the collection.
[0027] Among them, a gear 13 is provided at the upper end of the outer side of the upper storage tank 4, and a transmission block 14 is provided at the upper end of the transmission column 7, such as... Figure 3 As shown, the transmission block 14 and the gear 13 are welded and fixed together through the upper storage tank 4. The lower end of the transmission block 14 is provided with a threaded rod 5. One end of the threaded rod 5 extends into the inside of the transmission column 7, and the outside of the threaded rod 5 is threaded with the inside of the transmission column 7. The rotation of the threaded rod 5 can generate relative movement with the inside of the transmission column 7. The rotation of the threaded rod 5 can drive and adjust the longitudinal horizontal position of the transmission column 7, which can drive the first scraping plate 8 to be further stored, so that the first scraping plate 8 is stored inside the upper storage tank 4.
[0028] Example 2
[0029] To improve the stability of the transmission column 7 during longitudinal horizontal position adjustment, a sliding rod 6 is provided on the other side of the threaded rod 5. The upper end of the sliding rod 6 is welded and fixed to the lower end of the transmission block 14, and the lower end of the sliding rod 6 is embedded in the transmission column 7 and slidably connected to the interior of the transmission column 7. While the threaded rod 5 rotates and generates relative motion with the interior of the transmission column 7, the sliding rod 6 restricts the transmission column 7, causing the transmission column 7 to change from rotational motion to longitudinal linear motion, directly adjusting the horizontal position of the first scraping plate 8 and the transmission column 7.
[0030] Example 3
[0031] To facilitate scraping the inner wall of the conical section at the lower end of the lower liquid collection tank 1, such as... Figure 5 As shown, an inclined second scraping plate 10 is provided at the lower end of the first scraping plate 8. The second scraping plate 10 and the first scraping plate 8 are integrally formed. The inside of the first scraping plate 8 and the second scraping plate 10 facing the lower liquid receiving tank 1 is provided with a discharge chamber 9. After the first scraping plate 8 and the second scraping plate 10 scrape different positions inside the lower liquid receiving tank 1, the scraped electrolyte will flow into the discharge chamber 9. The electrolyte will follow the discharge chamber 9 and finally be discharged from the lower end of the lower liquid receiving tank 1.
[0032] Working principle: The electrolyte of the retired power battery is transported into the lower collection tank 1 through the filling pipe 2. Opening the solenoid valve 3 actively discharges the electrolyte from the lower collection tank 1. The motor at the upper end of the threaded rod 5 is started, and its output drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 creates relative motion with the inside of the transmission column 7. The transmission column 7 slides outside the sliding rod 6 after being restrained by the sliding rod 6. Simultaneously, the motor corresponding to one of the second rotating shafts 15 is started. The output of this motor drives the transmission rod 11 to rotate. The transmission rod 11 rotates counterclockwise around the second rotating shaft 15. This counterclockwise rotation pushes the transmission rod 11 and a... The first scraping plate 8 is connected to the end. After being pushed, the first scraping plate 8 will simultaneously drive the second scraping plate 10 to contact the electrolyte position against the inner wall of the lower liquid receiving tank 1. The motor at the upper end of the gear 13 starts. The motor can drive the transmission block 14 at the lower end to rotate at the upper end inside the upper storage tank 4 through the gear 13. During the rotation, the first scraping plate 8 and the second scraping plate 10 that are in contact with the inner wall of the lower liquid receiving tank 1 will rotate. The electrolyte that the first scraping plate 8 and the second scraping plate 10 rotate and scrape against the inner wall of the lower liquid receiving tank 1 will flow into the discharge chamber 9. After flowing into the discharge chamber 9, it will continue to flow along the discharge chamber 9 and finally be discharged from the bottom of the lower liquid receiving tank 1 through the solenoid valve 3.
