Description

Technical Field

[0001] The utility model relates to the technical field of sodium positive electrode material processing, in particular to a pressing plate of a sodium positive electrode material processing and leveling mechanism. Background Art

[0002] The positive electrode materials of sodium ion batteries are mainly divided into five types: oxides, polyanions, Prussian blue, fluorides, and organic compounds. After the positive electrode materials are processed, they need to be placed in a sealed can for sealed storage to prevent the materials from being polluted and corroded by the external environment, ensuring the quality and stability of the positive electrode materials for long-term storage. In order to improve the storage capacity of the sealed can, a leveling mechanism is needed to continuously compact the positive electrode materials in the sealed can and expel the internal air. The leveling mechanism achieves the leveling and compaction of the positive electrode materials through a pressing plate. The existing pressing plates are mostly a whole. When pressing plates of different specifications are needed, pressing plates of different specifications need to be replaced, resulting in high costs. Utility Model Content

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4As shown, a pressing plate of a sodium positive electrode material processing and leveling mechanism comprises a central portion and an outer ring portion, at least one set of connecting portions is arranged between the central portion and the outer ring portion, the central portion comprises a column 1, a connecting end 2 is arranged at the upper end of the column 1, an outer thread is provided on the outer surface of the connecting end 2, a central plate 3 is arranged on the lower end surface of the column 1, the outer ring portion comprises an outer ring plate 4, the connecting portion comprises a connecting plate 5, the outer ring plate 4 is located outside the central plate 3, the connecting plate 5 is used to fill the blank area between the central plate 3 and the outer ring plate 4, the upper surface of the central plate 3 and the upper surface of the connecting plate 5 Guide rods 6 are evenly arranged on the surface, and grooves 7 matching with the guide rods 6 are arranged on the upper surfaces of the connecting plates 5 and the outer ring plates 4. Adjacent guide rods 6 and grooves 7 are mutually engaged and connected by bolts 8. Reinforcement plates 9 are arranged on the center plate 3, the connecting plates 5 and the outer ring plates 4. The reinforcement plates 9 on the center plate 3 are fixedly connected to the guide rods 6 on the center plate 3, the reinforcement plates 9 on the connecting plates 5 are respectively fixedly connected to the guide rods 6 and the grooves 7 on the connecting plates 5, and the reinforcement plates 9 on the outer ring plates 4 are fixedly connected to the grooves 7 on the outer ring plates 4.

[0018] The pressing plate is used in conjunction with a leveling mechanism when in use. The power source of the leveling mechanism is a hydraulic cylinder. The pressing plate is threadedly connected to the output end of the hydraulic cylinder via a connecting end 2, and the lifting and lowering of the pressing plate is controlled by the movement of the output end of the hydraulic cylinder.

[0019] The specifications of the center plate 3, the connecting plate 5 and the outer ring plate 4 are set according to the specifications of the actual sealed can. The cross-section of the sealed can is circular, and the inner diameter of the sealed can is slightly larger than the outer diameter of the pressure plate after assembly. The pressure plate may include at least one center portion, or may include a center portion and at least one connecting portion, or may include a center portion, an outer ring portion and all connecting portions that can be installed between the center portion and the outer ring portion, which can meet the use of sealed cans of various specifications.

[0020] The reinforcing plates 9 are used to improve the connection stability between the central portion, the connecting portion and the outer ring portion, and the heights of the reinforcing plates 9 on the central plate 3, the connecting plate 5 and the outer ring plate 4 are gradually reduced.

[0021] Furthermore, after the guide rod 6 and the slot 7 are fixed together by the bolts 8, the upper surface of the guide rod 6 and the upper surface of the slot 7 matching the guide rod 6 form a smooth arc surface. By observing and touching whether the arc surface formed by the guide rod 6 and the slot 7 matching the guide rod 6 is smooth, it can be judged whether the through holes on the guide rod 6 and the slot 7 are aligned, which facilitates the subsequent accurate, stable and rapid fixing of the guide rod 6 and the slot 7 by the bolts 8.

[0022] Furthermore, the lower end surface of the slot 7 and the upper end surface of the guide rod 6 are both provided with chamfers, so as to facilitate the quick matching of the guide rod 6 and the slot 7 .

[0023] Furthermore, the orthographic projections of the guide rod 6 on the center plate 3, the connecting plate 5 and the outer ring plate 4 are respectively located inside the center plate 3, the connecting plate 5 and the outer ring plate 4, preventing the guide rod 6 from scratching the inner wall of the sealing tank.

[0024] Working principle: When installing the connecting plate 5, first disassemble the connecting end 2 and the hydraulic cylinder in the leveling mechanism, place the center plate 3 on the ground, and then select a suitable connecting plate 5, first lift the connecting plate 5 above the center plate 3, and then align the slot 7 on the connecting plate 5 with the guide rod 6 on the center plate 3, and then control the connecting plate 5 to move downward until the through hole on the guide rod 6 and the through hole on the slot 7 are completely corresponding, and then fix the slot 7 and the guide rod 6 together with the bolt 8, so as to complete the installation of the connecting plate 5, continue to install the connecting plate 5 on the outside of the connecting plate 5, and install the outer ring plate 4 on the outside of the connecting plate 5, which is the same as the method for installing the connecting plate 5 on the outside of the center plate 3, and will not be repeated here.

[0025] Since the pressure plate has a split structure, it can be added or removed according to the requirements of the inner diameter of the sealed can, thereby adjusting the specifications of the pressure plate. Compared with the traditional integrated pressure plate, it can reduce the number of pressure plates, reduce costs, facilitate installation, and have good use effect.

[0026] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
