Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for lithium battery materials with stable temperature control. Background Technology

[0002] With the development of science and technology, lithium batteries have become mainstream. The production of lithium battery materials requires the use of reaction vessels for material mixing and reaction. When using reaction vessels to mix lithium battery materials, temperature control is particularly important, as it affects the reaction rate and the effect of the reaction.

[0003] A Chinese patent with publication number CN219463388U discloses a reactor for processing carbon anode materials for lithium batteries. The reactor includes a reactor body, a feed hopper on the top wall of the reactor body, a discharge pipe on the bottom wall of the reactor body, a pulverizing chamber on the lower inner top wall of the reactor body, the top of the pulverizing chamber being connected to the feed hopper, an opening on the bottom wall of the pulverizing chamber, a pulverizing and dispersing processing component inside the pulverizing chamber, and an anti-sedimentation and agitation reaction component on the bottom side inside the reactor body.

[0004] Regarding the aforementioned technologies, it has been found that in the existing reactor processing, the raw materials in the reactor body can only be heated through the heating mechanism in the jacket. This not only results in slow temperature transfer but also easily leads to uneven heating, which is not conducive to efficient and uniform heating. Utility Model Content

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0025] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

By designing the drive component 8 with a structure in which the top motor 81 and the threaded rod 82 mate, it is easy to use. The top motor 81 can drive the threaded rod 82 to rotate during operation. Then, the engagement of the threaded rod 82 with the threaded sleeve 711 enables the threaded sleeve 711 to be driven to rise and fall stably, thereby driving the temperature control component 7 to adjust its overall height. A guide rod 512 for sliding installation of the center frame 71 is mounted on the lower end face of the base plate 51. A stabilizing seat 611 for mounting the lower ends of the threaded rod 82 and the guide rod 512 is also fitted on the rotating shaft 61.

[0034] In this embodiment, in actual processing, the stirring motor can drive the stirring frame to rotate. When heating is required during the stirring process, the electric heating tube can be activated. Then, the driving component drives the temperature control component to move up and down stably, so as to achieve stable and uniform heating of the raw materials in the heat-insulating inner liner. Furthermore, the heated liquid can be injected into the heat exchange bend through the liquid inlet pipe group. The heated liquid is used to assist in heating the materials in the heat-insulating inner liner, thereby ensuring that the material processing can be carried out in a stable temperature environment.
