Technical Field

[0001] This utility model relates to the field of preparation device technology, specifically to a preparation device for preparing lithium manganese oxide by mixing precursors. Background Technology

[0002] Lithium-ion power batteries are currently recognized both domestically and internationally as the most promising vehicle batteries, mainly composed of positive electrode materials, negative electrode materials, separators, and electrolytes. Among these, the positive electrode material is a crucial component of lithium-ion batteries and a key factor determining their performance. Existing methods for preparing lithium manganese oxide using precursor mixing involve a continuous feeding process, requiring manual intervention to stop the feeding from the upper feeding device. Furthermore, existing feeding methods often clog the preparation container opening, potentially resulting in uneven particle or lumpy material after preparation, which affects the structure and performance of the precursor. Therefore, this paper proposes a preparation apparatus for lithium manganese oxide using precursor mixing to address these issues. Utility Model Content

[0024] Furthermore, the irregularly shaped feed pipe 3 is inserted into both ends of the feeding assembly 4, and the feeding assembly 4 is provided with a first material holding assembly 5 and a second material holding assembly 6.

[0025] Furthermore, both the first material holding component 5 and the second material holding component 6 are connected to the irregularly shaped feed pipe 3, and the middle part of the curved pipe section 301 is bent into a U-shape.

[0026] Above the feeding component 4, there are a first feeding component 5 and a second feeding component 6. Different materials are placed in the first feeding component 5 and the second feeding component 6, and then enter the preparation host 1 through the irregular feeding pipe 3 for mixing. A curved section 301 is provided in the middle of the irregular feeding pipe 3 to slow down the feeding speed.

[0027] In this embodiment, a sliding groove 1201 is provided above the support base 12, and one end of the sliding groove 1201 is provided with an opening. At the same time, the lower part of the rack block 10 is slidably connected inside the sliding groove 1201.

[0028] Furthermore, there is a distance between one side of the support base 12 and the outer wall of the irregular feed pipe 3, and the upper structures of the two support feed racks 2 are the same and symmetrical.

[0033] Working principle:

[0034] Supporting feed racks 2 are provided at both ends of the preparation host 1, and the lower part of the irregularly shaped feed tube 3 is inserted above the supporting feed racks 2. At the same time, the feeding assembly 4, the first feeding assembly 5, and the second feeding assembly 6 are respectively provided above the irregularly shaped feed tube 3. A support base 12 is provided on one side above the supporting feed rack 2, and an electric telescopic rod 11 and a rack block 10 are respectively provided above the support base 12. The electric telescopic rod 11 pushes the rack block 10, and the rack block 10 meshes with the gear 9 below it. One end of the rotating column 8 is inserted into the gear 9, and the other end of the rotating column 8 is inserted into the irregularly shaped feed tube 3 and connected to the semi-circular stop block 7. When the first feeding assembly 5 and the second feeding assembly 6 feed material, the material will pass through the semi-circular stop block 7. Figure 4This is when the semicircular stop 7 is in a vertical state, and the material can descend from both sides of the semicircular stop 7. When the on-site staff starts the electric telescopic rod 11 to pull back the rack block 10 according to the mixing situation inside the preparation host 1, the gear 9, the rotating column 8 and the semicircular stop 7 will rotate 90 degrees, so that the semicircular stop 7 is in a horizontal state, blocking the lower part of the irregular feed pipe 3, so that the material is inside the irregular feed pipe 3. And according to the mixing situation inside the preparation host 1, the first material holding component 5 or the second material holding component 6 can be opened or closed respectively.

[0035] In addition, a curved tube section 301 is provided above the irregularly shaped feed tube 3. When the first material holding component 5 and the second material holding component 6 feed the preparation host 1, the special shape of the curved tube section 301 can buffer the material feeding. At the same time, when the semi-circular stop block 7 is blocked, the material will not directly impact the top of the semi-circular stop block 7, thus protecting its components.
