The top and bottom of the inner cavity of the two fixed blocks 5 are provided with sliding grooves 10, and the inner cavity of the sliding grooves 10 is slidably connected with a sliding block 11. The end of the sliding block 11 away from the sliding groove 10 is fixedly connected to the movable block 6, which can limit and guide the movable block 6 to move, increasing the sliding stability of the filter frame 701 when it sways left and right.

[0032] The working principle is as follows:

[0033] In operation, the first motor 401 is started to drive the transmission rod 402 to rotate, which in turn drives the stirring rod 403 to rotate, thus mixing the lithium battery slurry in the mixing tank 2. After mixing is complete, the discharge valve 9 is opened to quickly discharge the lithium battery slurry from the output hopper 3. At the same time, the scraper 404 scrapes off any remaining lithium battery slurry on the inner wall of the mixing tank 2. The discharged lithium battery slurry then falls into the filter frame 701, filtering the mixed lithium battery slurry and improving its quality. Simultaneously, the second motor 702 is started to drive the eccentric wheel 703 to rotate. At this time, the rotation of the eccentric wheel 703, with the cooperation of the fixed block 5 and the movable block 6, and the sliding connection of the sliding groove 10 and the sliding block 11, can squeeze the filter frame 701 to the right. At the same time, the setting of the spring 704 can provide the filter frame 701 with the reset elastic force, so that the filter frame 701 can swing left and right during filtration, improving the filtration effect, thereby filtering the impurities in the lithium battery slurry and improving the quality of the lithium battery slurry. Finally, the box door 13 is opened, and the filter frame 701 can be pulled out from the base 1 using the slide rail 15 and the slide groove 16, which is convenient for cleaning the impurities in the filter frame 701 and facilitating subsequent processing and use.

[0034] In summary, this lithium battery slurry premixing device uses a mixing component 4 to stir and mix the lithium battery slurry in the mixing tank 2. The output hopper 3 facilitates the rapid discharge of the lithium battery slurry. The scraper 404 removes residual lithium battery slurry from the inner wall of the mixing tank 2. The filter component 7 filters the mixed lithium battery slurry, improving its quality. The second motor 702 and eccentric wheel 703 compress the filter frame 701 to the right, while the spring 704 provides a restoring force to the filter frame 701, allowing it to sway left and right during filtration, thus improving the filtration effect.
