Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte reaction kettles, in particular to an electrolyte reaction kettle provided with a lithium salt quantitative addition structure. Background Art

[0002] With the advancement of science and technology, the energy sources of automobiles are becoming more and more diversified. Now, new energy vehicles such as hybrid vehicles and pure electric vehicles have emerged. Among them, pure electric vehicles generally use lithium batteries as the driving source. In the manufacturing process of lithium batteries, a reactor is required to prepare the electrolyte. However, the existing electrolyte reactor still has certain defects when used;

[0003] For example, a high-efficiency electrolyte reactor with announcement number CN215540873U, through the setting of the opening and closing mechanism, will touch the gravity sensor and generate pressure on it when adding electrolyte raw materials. When the pressure reaches the set value of the gravity sensor, it will control the telescopic rod to shorten and drive the first baffle and the second baffle to rotate downward, so that the electrolyte raw materials are added to the interior of the processing tank. When the addition is completed, the gravity sensor will control the telescopic rod to extend and drive the two baffles to rotate upward to automatically close, thereby effectively preventing the volatile gas of the electrolytic solution from escaping; at the same time, through the coordinated setting of the water tank, the water pump and the surrounding water cooling pipe, the interior of the processing tank can be quickly circulated and cooled to facilitate the processing of the next batch of raw materials, so that the use of the reactor can be more efficient, and its practicality is effectively improved;

[0004] In actual use, this type of electrolyte reactor can only add a fixed amount of electrolyte stock solution at one time, so different raw materials need to be added repeatedly through the feed port, resulting in cumbersome operation and low electrolyte preparation efficiency;

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original equipment. Therefore, we proposed an electrolyte reactor with a lithium salt quantitative addition structure that can solve the above problems well. Utility Model Content

[0006] The purpose of the utility model is to provide an electrolyte reactor with a lithium salt quantitative addition structure to solve the problem that the electrolyte reactor proposed in the above background technology can only add a fixed amount of electrolyte solution at one time during actual use, so different raw materials need to be added repeatedly through the feed port, resulting in cumbersome operation and low electrolyte preparation efficiency.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electrolyte reactor with a lithium salt quantitative addition structure, comprising a reactor, a support frame is fixedly connected to the bottom end of the reactor, a processing tank is fixedly connected to the inside of the reactor, a discharge pipe and a surrounding water cooling pipe are respectively arranged between the bottom ends of the reactor and the processing tank, a first motor is installed at the top of the reactor, the bottom output shaft of the first motor passes through the reactor and the processing tank in sequence and is fixedly connected to a rotating shaft, and a vertically arranged stirring member is fixedly connected to the outside of the rotating shaft;

[0008] The reactor and the processing tank are provided with three feed hoppers at the top, and the three feed hoppers are provided with opening and closing mechanisms inside. The processing tank is provided with a storage assembly at the top, which includes a fixed cylinder fixedly connected to the top of the inner wall of the processing tank. The top of the fixed cylinder is located below the three feed hoppers and has corresponding through grooves. The inside of the fixed cylinder is provided with a liquid storage tank at the bottom of the three through grooves, and the bottom of the fixed cylinder is provided with a plurality of leakage holes at the position of the liquid storage tank. Through the provision of the three feed hoppers, multiple raw materials such as electrolyte solution and water can be added to the processing tank at one time, and these raw materials can be temporarily stored through the fixed cylinder of the storage assembly, that is, there is no need to repeatedly add different raw materials, thereby simplifying the operation process and improving the preparation efficiency of the electrolyte.

[0009] The interior of the fixed cylinder is provided with a quantitative adding component for quantitatively adding the raw materials temporarily stored therein.

[0010] Preferably, the quantitative addition component includes a receiving groove opened at the bottom end of the fixed cylinder, the outer side of the rotating shaft is located inside the receiving groove and is rotatably connected with a rotating ring, and the outer side of the rotating ring is fixedly connected with three rotating baffles. Through the timed rotation of the rotating ring and the three rotating baffles, the three rotating baffles block or expose all the leakage holes of the corresponding liquid storage tanks, so that the raw materials temporarily stored in the liquid storage tank can be quantitatively added to the interior of the processing tank.

[0011] Preferably, a transmission assembly is provided at the bottom end of the rotating baffle, and the transmission assembly includes three connecting rods fixedly connected to the three rotating baffles respectively. Three sliding grooves are opened at the bottom end of the fixed cylinder, and the sliding grooves are arc-shaped groove structures.

[0013] Preferably, a timing controller is fixedly installed on the outer wall of the reactor below the second motor, and the timing controller is electrically connected to the second motor.

This can not only realize the complete storage of the rotating baffle by the receiving groove, but also enable the rotating baffle to completely block the leakage hole at the bottom of the liquid storage tank when the connecting rod rotates along the slide groove to drive the rotating baffle to rotate synchronously, so as to ensure the accuracy of quantitative addition.
