Description
Technical Field
[0001] The utility model belongs to the technical field related to electrode slurry production, and particularly relates to a lithium carbonate slurry sedimentation and extraction device. Background Art
[0002] Lithium carbonate, an inorganic compound, is a colorless monoclinic crystal or white powder. It is soluble in dilute acid, slightly soluble in water, and more soluble in cold water than in hot water. It is insoluble in alcohol and acetone. It can be used to make ceramics, medicines, catalysts, etc. It is a commonly used raw material for lithium-ion batteries. When producing lithium carbonate slurry, in order to ensure that the produced slurry has a uniform texture, it is necessary to perform sedimentation extraction to remove the settleable solids in the slurry and finally obtain a uniform slurry. However, it still has the following disadvantages in actual use:
[0003] After the lithium carbonate slurry is extracted by sedimentation, the upper clear liquid will be continuously discharged, so an overflow weir is required for discharge. Usually, the overflow weir is fixed on the extraction reactor. As the use time increases, the lithium carbonate is easy to scale in the overflow weir at the upper overflow weir structure, resulting in blockage of the overflow weir. The previous overflow weir was welded, which was not convenient to clean;
[0004] During the sedimentation extraction of lithium carbonate slurry, solids will fall to the bottom and then be concentrated in the discharge port for discharge, so that the solids in the lithium carbonate slurry are extracted and discharged. However, the solids in the slurry have poor fluidity and are easily deposited directly at the bottom of the reactor. Therefore, a scraper is required to increase the fluidity of the deposited solids in the lithium carbonate slurry. However, when scraping, the discharge port will also be blocked by the solids in the lithium carbonate slurry due to the poor fluidity of the solids, affecting the smoothness of the solid discharge. Utility Model Content

By arranging a reaction kettle, a top cover, an overflow weir and a driving motor, the utility model solves the problem that the overflow weir for discharging the upper clear liquid after the lithium carbonate slurry is sedimented and extracted is inconvenient to disassemble and clean, and the solids deposited after the extraction are easy to cause blockage to the discharge port.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model discloses a lithium carbonate slurry sedimentation and extraction device, comprising a reactor, a top cover, an overflow weir and a driving motor.

[0008] Furthermore, a concentrating shell is fixed at the bottom of the reactor, the long scraper and the short scraper are both arranged in the concentrating shell, and the output end of the concentrating shell is fixedly connected to a discharge port. The reactor concentrates the solids deposited in the lithium carbonate slurry through the concentrating shell and discharges them through the discharge port.
[0009] Furthermore, a slurry feed pipe is vertically fixed through the top cover on one side of the driving motor, and an overflow pipe is vertically fixed through the top cover on the side of the driving motor away from the slurry feed pipe. One end of the overflow pipe away from the top cover is arranged above the overflow weir. The top cover transports the lithium carbonate slurry to the reactor through the slurry feed pipe and outputs the lithium carbonate slurry through the overflow pipe.
[0010] Furthermore, a fixing frame is fixed on the peripheral side of the driving motor, and a mounting plate is symmetrically fixed on the outer side of the fixing frame.

[0026] See also Figure 1-6 The utility model is a lithium carbonate slurry sedimentation and extraction device, comprising a reactor 1, a top cover 2, an overflow weir 3 and a driving motor 5. A mounting frame 101 is fixed on the upper peripheral surface of the reactor 1, and the reactor 1 contains the lithium carbonate slurry therein. An overflow weir 3 is arranged on the side of the mounting frame 101 away from the reactor 1, and the overflow weir 3 is used to contain the supernatant overflowing after the lithium carbonate is extracted. A fixing bar 301 is fixed on the upper part of the side of the overflow weir 3 close to the reactor 1, and a plug plate 302 and the overflow weir 3 are connected together through the fixing bar 301. A plug plate 302 is fixed on the bottom of the fixing bar 301, and the plug plate 302 is plugged into the mounting frame 101. The plug plate 302 is plugged into the mounting frame 101, so that the overflow weir 3 can be installed on the outside of the reactor 1. When the overflow weir 3 needs to be disassembled and cleaned, the overflow weir 3 is pushed upward so that the plug plate 302 and the mounting frame After the reactor 1 is separated from the reactor 1, the overflow weir 3 can be removed immediately. After cleaning, the plug plate 302 is inserted into the mounting frame 101 to install the overflow weir 3. A top cover 2 is fixed to the top of the reactor 1, and the top of the reactor 1 is closed by the top cover 2. A driving motor 5 is fixed through the top cover 2, and a driving shaft 501 is fixed to the output end of the driving motor 5. A fixed plate 502 is symmetrically fixed to the lower part of the outer circumference of the driving shaft 501. A long scraper 503 is fixed to the end of the fixed plate 502 away from the driving shaft 501, and a short scraper 504 is fixed to the end of the fixed plate 502 away from the long scraper 503 away from the driving shaft 501. The driving motor 5 controls the driving shaft 501 to rotate, and the fixed plate 502 is driven to rotate by the rotation of the driving shaft 501. The long scraper 503 and the short scraper 504 are driven to move in the concentrated shell 102 by the rotation of the fixed plate 502.
[0027] Specifically, a concentrating shell 102 is fixed at the bottom end of the reactor 1, and the long scraper 503 and the short scraper 504 are both arranged in the concentrating shell 102. The output end of the concentrating shell 102 is fixedly connected to a discharge port 103. The reactor 1 concentrates the solids precipitated in the slurry in the reactor 1 into the discharge port 103 through the concentrating shell 102, and discharges the solids through the discharge port 103.
[0028] Furthermore, a slurry feed pipe 202 is vertically fixed through the top cover 2 on one side of the driving motor 5, and an overflow pipe 201 is vertically fixed through the top cover 2 on the side of the driving motor 5 away from the slurry feed pipe 202.

The ends of the long scraper 503 and the short scraper 504 that are close to each other are fixed on the circumference of the rotating block 506. When the long scraper 503 and the short scraper 504 are driven to rotate by the driving motor 5, the scraping blocks 505 are driven to scrape the solids deposited on the bottom of the concentration shell 102. The solids scraped by the long scraper 503 fall into the discharge port 103.

[0033] The operation process of this embodiment is as follows: during operation, when the lithium carbonate slurry in the reactor 1 is settled, the solids in the settled lithium carbonate slurry fall into the concentrated shell 102, and at this time, the drive motor 5 is started to drive the drive shaft 501 to rotate to drive the fixed plate 502 to rotate, and the long scraper 503 and the short scraper 504 are driven to move in the concentrated shell 102 through the rotation of the fixed plate 502. When the long scraper 503 and the short scraper 504 rotate, the scraper block 505 is driven to scrape the solids in the concentrated shell 102, and the solids scraped on the long scraper 503 fall into the discharge port 103. At the same time, when the scraper block 505 on the short scraper 504 rotates, it further assists in scraping the solids to fall into the discharge port 103. After the solids in the concentrated shell 102 fall into the discharge port 103, the small scraper 508 rotates to increase the fluidity of the lithium carbonate solids in the discharge port 103, and the solids in the lithium carbonate slurry in the discharge port 103 are discharged.
