Description

Technical Field

[0001] The utility model relates to the technical field of lithium ion battery slurry reflow, in particular to a lithium ion battery slurry reflow device. Background Art

[0002] Lithium battery slurry is mainly composed of active materials, conductive agents, binders and solvents. Its dispersed phase is composed of particles of different particle sizes, morphologies and densities. The corresponding dispersion media are divided into oily solvent NMP (often used as positive electrode slurry solvent) and aqueous solvent deionized water (often used as negative electrode slurry solvent).

[0003] For example, a lithium-ion battery slurry reflux device with the authorization announcement number "CN220214725U" is equipped with a movable column, a stirring blade, a connecting rod, a cleaning scraper, a mounting plate, a connecting column, a bidirectional screw, a movable block, a connecting block and a supporting block. The cleaning scraper is driven by a servo motor to scrape and clean the inner wall of the turnover tank of the lithium-ion battery slurry, and the support block is used to clamp and support the conveying pipe and the reflux pipe of the lithium-ion battery slurry, thereby achieving the advantages of supporting the conveying pipe and the reflux pipe of the lithium-ion battery slurry and scraping and cleaning the inner wall of the turnover tank.

[0004] The above-mentioned servo motor drives the stirring blade and the cleaning scraper to stir the lithium-ion battery slurry. The working mode of the stirring structure is too monotonous and can only stir the lithium-ion battery slurry in the same direction, which has low working speed and efficiency. At the same time, after the lithium-ion battery slurry is transported to the turnover tank, the conveying pipeline is connected to it and the valve is far away, causing the lithium-ion battery slurry to flow into the conveying pipeline and not be stirred at this place, thereby reducing the stirring quality.

[0030] Working principle:

[0031] Lithium-ion battery slurry reflux stirring work:

[0032] When the lithium-ion battery slurry needs to be refluxed, the feed pipe 7 and the discharge pipe 6 are connected to the external filter cloth buffer tank, and then the valve installed on the feed pipe 7 is opened to allow the lithium-ion battery slurry to flow into the tank body 3 through the feed pipe 7 and the valve is closed. Subsequently, the external power supply of the first motor 102 is turned on, and the first motor 102 is started to drive the first bevel gear 103 to rotate. The rotation of the first bevel gear 103 drives the second bevel gear 104 and the third bevel gear 105 to rotate relative to each other. The rotation of the second bevel gear 104 can drive the vertical rod 106 to rotate clockwise through the bearing in the third bevel gear 105 and the frame 107. The rotation of the third bevel gear 105 can drive the frame 107 and the two scrapers 9 to rotate counterclockwise in the tank body 3. In this way, the lithium-ion battery slurry can be stirred by relative rotation of multiple blades installed on the surface of the vertical rod 106 and the frame 107. The rotation of the frame 107 can drive the two scrapers 9 to rotate synchronously. Since the two scrapers 9 are in contact with the inner wall of the tank body 3, the lithium-ion battery slurry is prevented from sticking to the inner wall.

[0033] Lithium-ion battery slurry reflux discharge work:

[0034] When the lithium-ion battery slurry is stirred, the external power supply of the second motor 202 is turned on, and the second motor 202 starts to drive the worm 203 to rotate in the second box 201 through the bearing. The rotation of the worm 203 can drive the worm wheel 204 to rotate in the second box 201, and the worm wheel 204 drives the disc 205 to rotate clockwise, and the straight plate 206 is driven to slide rightward in the slideway processed on the inner wall of the second box 201 through the protruding cylinder on the surface of the disc 205 and the slide groove processed on the surface of the straight plate 206. The rightward sliding of the straight plate 206 drives the square plate 11 to move rightward;

[0035] The slide groove processed on the surface of the square plate 11 and the raised cylinder on the surface of the straight rod 12 drive the straight rod 12 to slide downward in the second box body 201. The downward sliding of the straight rod 12 drives the rubber block 10 to move downward in the discharge port 5. When the upper surface of the rubber block 10 is flush with the lower end of the discharge pipe 7, the second motor 202 stops rotating, and then the lithium-ion battery slurry in the tank body 3 is extracted into the external filter cloth storage tank for subsequent processing through the external pneumatic diaphragm pump and the discharge pipe 6. In this way, the lithium-ion battery slurry in the tank body 3 can be discharged.
