Description

Technical Field

[0001] The utility model relates to the field of lithium ion battery material sintering equipment, in particular to an experimental reaction kettle for ternary precursors. Background Art

[0002] The preparation of ternary precursor refers to the synthesis of nickel, cobalt and manganese hydroxide (ternary precursor) through a series of chemical process steps. Specifically, raw materials such as nickel salt, cobalt salt and manganese salt are dissolved in a solvent in a certain proportion, and then these metal ions are precipitated under specific conditions (such as temperature, pH value and stirring speed) through reaction methods such as co-precipitation to form a hydroxide precipitate with a specific structure and composition. After subsequent treatments such as aging, washing and drying, the ternary precursor is finally obtained. The most important reaction equipment is the reactor with the corresponding reaction environment.

[0003] The utility model with the existing authorization application number CN202121047619.X discloses a ternary material precursor reactor. The above-mentioned technical scheme is adopted. Although the reactor cover is automatically raised or lowered by setting a lifting device, which saves manpower operation, avoids facial contact with the chemicals in the reactor, and ensures the physical safety of the operator, a sealing device is set to prevent lubricating grease or shaft sleeve wear debris from entering the reactor along the stirring shaft, affecting product quality and analytical experimental results. The material in the reactor is fully stirred by setting a stirring device to obtain higher mixing efficiency, better heat transfer performance, and efficient solid-liquid suspension capacity and liquid-liquid dispersion capacity. However, the generated ternary precursor is a precipitated solid, and its discharge valve discharges a solid-liquid mixture. The discharge structure lacks a solid-liquid separation filtering structure, resulting in the need to collect all the solid-liquid mixtures and then filter them separately when collecting the ternary precursor, making the collection process of the ternary precursor solid more cumbersome, time-consuming and labor-intensive.

DETAILED DESCRIPTION

[0021] See also Figure 1-5The experimental reactor for ternary precursors includes a reactor body 1 and a storage bucket 3. A sealing cover 2 is arranged above the storage bucket 3. The bottom end of the storage bucket 3 is fixedly connected to a waste discharge pipe 8. The outer surface of the storage bucket 3 is fixedly connected to a support ring plate 13. The bottom surface of the support ring plate 13 is fixedly connected to three support legs 14. By providing the support ring plate 13 and the support legs 14, it is convenient to support the bottom of the storage bucket 3 after the storage bucket 3 is removed from the sealing cover 2, thereby facilitating the separate and stable placement of the storage bucket 3.

[0022] The inner wall of the sealing cover 2 is fixedly connected with a sealing ring 15, and the bottom surface of the sealing ring 15 is in contact with the top of the storage bucket 3. By providing the sealing ring 15, it can be placed between the sealing cover 2 and the storage bucket 3 to increase the sealing performance of the two. The upper surface of the sealing cover 2 is fixedly connected with a connecting component, which includes a nut barrel 7, a high-pressure solenoid valve 4, a connecting pipe 5 and a threaded pipe 6. The high-pressure solenoid valve 4 is arranged on the nut barrel 7, and the connecting pipe 5 is connected to the input end of the high-pressure solenoid valve 4 and the bottom end of the kettle body 1. The threaded pipe 6 is connected to the output end of the high-pressure solenoid valve 4. The outer surface of the threaded tube 6 is threadedly connected to the inner wall of the nut tube 7, and the outer surface of the waste pipe 8 is fixedly connected with an anti-slip sleeve 19, and the outer surface of the anti-slip sleeve 19 is fixedly connected with four anti-slip convex rings 20. By providing the anti-slip convex rings 20, the friction force of the outer surface of the anti-slip sleeve 19 can be increased, and then the anti-slip sleeve 19 and the anti-slip convex rings 20 can jointly increase the friction force of the outer surface of the waste pipe 8, thereby facilitating the outer surface of the waste pipe 8 to be stably and sealedly connected to the external diversion hose.

[0023] The outer surface of the sealing cover 2 is fixedly connected with three fixing rods 10, the outer surface of the storage bucket 3 is fixedly connected with three limiting rods 11, the outer surface of the storage bucket 3 is fixedly connected with two handle supports 16, and the inner wall of each handle support 16 is fixedly connected with a pull rod 17. By providing the pull rod 17, a rotation base surface can be provided for the hand-gripping structure in the handle support 16, thereby increasing the use flexibility of the hand-gripping structure. By providing the handle support 16 and the pull rod 17, the storage bucket 3 can be lifted and carried separately in cooperation with the above-mentioned hand-gripping structure.

[0024] Three limit plates 12 are provided on the outer side of the sealing cover 2, and the inner wall of the storage bucket 3 is fixedly connected to the filter plate 9. The inner wall of each limit plate 12 is rotatably connected to the outer surface of the fixing rod 10, and the interior of each limit plate 12 is clamped with the outer surface of the limit rod 11. A handle 18 is provided inside each handle support 16, and the inner wall of each handle 18 is rotatably connected to the outer surface of the pull rod 17. By providing the handle 18, it can be rotated around the outer surface of the pull rod 17 inside the handle support 16, so that the storage bucket 3 can be easily lifted and carried separately.

[0025] The working principle of the utility model is: first, the raw materials for preparing the ternary precursor are stirred and heated normally using the kettle body 1, and then before the prepared ternary precursor solid-liquid mixture in the kettle body 1 is discharged, a hose for external diversion is put on the waste discharge pipe 8, and then the high-pressure solenoid valve 4 is energized to connect the connecting pipe 5 and the threaded pipe 6, and the ternary precursor solid-liquid mixture in the kettle body 1 enters the interior of the storage bucket 3 through the connecting pipe 5, the high-pressure solenoid valve 4, the threaded pipe 6, the nut tube 7 and the sealing cover 2 respectively, while the solid part of the ternary precursor is blocked on the filter plate 9, and the waste liquid flows out from the waste discharge pipe 8 and the external hose after passing through the filter plate 9. When the ternary precursor solid-liquid mixture in the kettle body 1 is completely discharged, the three limit switches are respectively moved. After the plate 12 rotates around the fixed rod 10 and moves away from the clamping connection of the limit rod 11, the two handles 18 are then grasped to separate the receiving bucket 3 from the sealing cover 2, and the receiving bucket 3 is placed separately and stably with the support of the supporting legs 14. Subsequently, the filtered ternary precursor solids on the filter plate 9 are poured out, and the receiving bucket 3 and the sealing cover 2 can be stably docked. In this way, the collection of the solid part of the ternary precursor becomes efficient and simple. The design of the entire ternary precursor experimental reactor effectively solves the problem that when collecting the ternary precursor, all solid-liquid mixed substances need to be collected and then filtered separately due to the lack of a solid-liquid separation filtration structure at the discharge structure, making the collection process of the ternary precursor solid more cumbersome, time-consuming and labor-intensive.

[0026] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
