Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a dryer for drying ternary precursor materials. Background Art

[0002] Ternary precursor materials, namely lithium nickel cobalt manganese oxide, are precursors to ternary composite cathode materials suitable for automotive power batteries and lithium-ion secondary batteries. Ternary precursor materials are loose powders with poor fluidity. Depending on the production process and formulation, the moisture content before drying is generally around 20%, and the final moisture content is required to be around 0.2%. Currently, disc dryers are commonly used to dry ternary precursor materials.

[0003] A disc dryer is a type of drying equipment that primarily utilizes heat conduction. It typically consists of a housing with a feed hopper at the top and a discharge port at the bottom. Inside the housing, a rotating shaft and a drying disc coaxial with the shaft are vertically mounted. A rake arm, each equipped with rake blades, is mounted on the drying disc. During the drying process, a wet ternary precursor can be added to the housing through the feed hopper. Gravity causes the wet precursor to fall onto the drying disc. The rake arm then rotates with the shaft, driving the rake blades to continuously stir the wet material on the drying disc, evenly heating and drying it.

[0004] At present, when the feed hopper of the existing disc dryer is in use, the ternary precursor wet material is sticky and easily adheres to the inner wall of the feed hopper when added into the feed hopper, requiring workers to manually shovel it off, which is troublesome, time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of the present utility model is to provide a dryer for drying ternary precursor materials in order to solve the above-mentioned problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical scheme: a dryer for drying ternary precursor materials, including a body, a feed hopper is provided on the top of the body, a shoveling mechanism is provided inside the feed hopper, a feed port is provided on the top of the feed hopper, the shoveling mechanism includes a cover for closing the feed port, a plurality of locking components for fixing the cover are provided circumferentially on the feed port, a shoveling paddle and a driving component for driving the shoveling paddle to rotate are provided on the cover, and the shoveling paddle is used to be inserted into the feed hopper and to contact the inner circumferential wall of the feed hopper.

[0007] As a further configuration of the present invention, the drive assembly includes a drive motor fixedly connected to the top of the cover, the output end of the drive motor is connected to a rotating shaft, and the shoveling paddle is fixedly connected to the rotating shaft.

[0009] As a further configuration of the present invention, the scraper is detachably mounted on the frame and is made of rubber material.

[0010] As a further configuration of the present invention, an inserting block is provided on the scraper, and slots for inserting the inserting block are vertically opened on both side walls of the frame.

[0011] As a further configuration of the present invention, the locking assembly includes a connecting seat fixedly connected to the feed port, a clamping arm is rotatably connected to the connecting seat, an end of the clamping arm away from the connecting seat is threadedly connected to a threaded rod, and a plurality of threaded holes matching the threaded rod are provided on the cover and the feed port.

[0012] As a further configuration of the present invention, a gripping knob is provided on the threaded rod.

[0013] As a further configuration of the present invention, a lifting handle is provided on the cover.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] When the utility model is in use, the ternary precursor wet material can be added into the feed hopper through the feed port, and then the sealing cover is closed on the feed port to close the feed port, so that the shoveling paddle is inserted into the feed hopper. The shoveling paddle can be rotated by the driving component. Since the shoveling paddle contacts the inner peripheral wall of the feed hopper, the inner peripheral wall of the feed hopper can be continuously scraped during the rotation. When the ternary precursor wet material adheres to the inner peripheral wall of the feed hopper, it can be automatically shoveled off by the shoveling paddle. After the operation is completed, the sealing cover can be opened and the shoveling paddle can be removed to facilitate the cleaning of the shoveling paddle surface. The operation is relatively convenient and simple, avoids the adhesion of the ternary precursor wet material, is highly efficient, and saves time and effort. BRIEF DESCRIPTION OF THE DRAWINGS
