  • Slurry filtering apparatus and coating system
    Patent number: 12121833
    Abstract: Embodiments of this application relate to the field of lithium battery production technologies and disclose a slurry filtering apparatus and a coating system. The slurry filtering apparatus may include a rotating filter element and a gravity filter. The gravity filter may be provided with a feed port and a first discharge port. A height of the feed port on the gravity filter may be greater than that of the first discharge port on the gravity filter. The rotating filter may be connected to the feed port and is configured to provide a positive-pressure filtered slurry to the gravity filter. The first discharge port may be configured to convey a slurry filtered by the gravity filter to a coating apparatus.
