The electrolyte plays the role of conducting ions between the positive and negative electrodes of the lithium battery, which is the guarantee for the high voltage and high specific energy of the lithium-ion battery. The electrolyte is generally prepared by mixing high-purity organic solvent, electrolyte lithium salt, necessary additives and other raw materials under certain conditions and in a certain proportion. In the lithium battery production process, an electrolyte raw material transport device is required to transport the electrolyte.

[0003] Chinese utility model patent application number "CN202321547298.9" proposes a "double-sided flow channel type liquid flow frame structure and electrolyte transmission structure for flow batteries". The beneficial effect of the utility model is that it proposes a double-sided flow channel type liquid flow frame structure, in which the negative electrode inlet flow channel and the negative electrode outlet flow channel are set on both sides of the liquid flow frame body. The flow channels on both sides are connected by two liquid passage holes, thereby extending the flow channel length and reducing the branch current. However, the above device does not have an anti-crystallization device during use, which may cause the electrolyte raw material to crystallize during transmission, thereby reducing the practicality of the electrolyte raw material and affecting its performance, thus reducing the practicality of the transmission device. Therefore, a lithium battery electrolyte raw material anti-crystallization transmission device is proposed to solve the above problems. Summary of the Invention

[0006] The anti-crystallization mechanism includes a heating box, which is located above the receiving tank. The inner wall of the heating box is provided with heating wires, and the inner bottom wall of the heating box is provided with a heating plate. A temperature regulating component is provided on the outside of the heating box. An air pump is provided above the receiving tank. The air pump's suction port is fixedly connected to a suction pipe that extends into the heating box, and the air pump's exhaust port is fixedly connected to an exhaust pipe.

[0007] Furthermore, it also includes a support frame, which is fixedly installed on the outside of the storage tank. A liquid pump is provided above the support frame.

[0011] Furthermore, the heating box is located outside the liquid outlet pipe, and the length of the heating box is the same as the length of the portion of the liquid outlet pipe located outside the receiving tank.

[0012] Furthermore, both the storage tank and the receiving tank are provided with two support legs on their exteriors, and the two support legs are symmetrical about the center of the storage tank and the receiving tank, respectively.

[0013] Furthermore, the temperature regulating component is electrically connected to the heating wire, the heating plate, and the air pump.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0024] In this embodiment, see Figure 1-4 A lithium battery electrolyte raw material anti-crystallization transfer device includes a storage tank 1 and a receiving tank 2, and an anti-crystallization mechanism 7 is provided on the outside of the receiving tank 2.

[0025] The anti-crystallization mechanism 7 includes a heating box 71, which is located above the receiving tank 2. The inner wall of the heating box 71 is provided with a heating wire 72, the inner bottom wall of the heating box 71 is provided with a heating plate 73, and the outside of the heating box 71 is provided with a temperature regulating component 74. A vacuum pump 75 is located above the receiving tank 2. The suction port of the vacuum pump 75 is fixedly connected to a suction pipe 76 that extends into the interior of the heating box 71, and the exhaust port of the vacuum pump 75 is fixedly connected to an exhaust pipe 77.

[0026] It should be noted that after the heating wire 72 and the heating plate 73 are powered on, the temperature inside the heating box 71 can be adjusted. At the same time, a temperature sensor is installed inside the heating box 71. The temperature sensor is electrically connected to the temperature adjustment component 74. The purpose of this is that the temperature sensor transmits the temperature signal inside the heating box 71 to the temperature adjustment component 74 to adjust the temperature inside the heating box 71, so as to keep the temperature inside the heating box 71 stable.

[0027] Technical effect: By using the heating box 71, heating wire 72, heating plate 73, temperature adjustment component 74, air pump 75, air suction pipe 76 and exhaust pipe 77 in combination, the temperature inside the heating box 71 can be adjusted, so that the temperature inside the liquid pipe 6 is higher than the crystallization temperature of the electrolyte raw material, thereby avoiding the crystallization of the electrolyte raw material during the transmission process and improving the practicality and convenience of the transmission device.

[0028] Optionally, see Figure 1-2 It also includes a support frame 3, which is fixedly installed on the outside of the storage tank 1. A liquid pump 4 is provided above the support frame 3. The liquid pump 4 has a suction port with one end extending into the inside of the storage tank 1 and a liquid outlet port connected to a liquid outlet pipe 6 extending into the inside of the receiving tank 2.

[0029] Technical effect: By using the combined use of the liquid pump 4, the liquid suction pipe 5 and the liquid discharge pipe 6, the electrolyte raw materials can be transported, thereby enabling the electrolyte raw materials to be transported from the storage tank 1 to the inside of the receiving tank 2, which facilitates the transportation of electrolyte raw materials.

[0030] Optionally, the heating box 71 is provided with a support rod 8 for support, and the heating box 71 is provided with two fixing plates 9. The two fixing plates 9 are threadedly connected to a bolt 10 with one end penetrating into the receiving tank 2.

[0031] Technical effect: By using the combination of fixing plate 9 and bolt 10, the purpose is to fix the heating box 71, so that the heating box 71 can be more stable after installation and will not cause danger due to shaking.

[0032] Optionally, the storage tank 1 has an installation groove 11 inside, and multiple heating components 12 are installed inside the installation groove 11. The function of the heating components 12 is to heat the inside of the storage tank 1, so that the temperature inside the storage tank 1 is higher than the crystallization temperature of the electrolyte raw material, thereby preventing the electrolyte raw material from crystallizing inside the storage tank 1.

[0033] It should be added that the receiving tank 2 is also equipped with a heating component 12, which facilitates heating the inside of the receiving tank 2 and also makes the temperature inside the receiving tank 2 higher than the crystallization temperature of the electrolyte raw material, thus facilitating the storage of the electrolyte raw material.

[0034] Optionally, multiple heating wires 72 are provided, and multiple heating wires 72 are respectively arranged on the inner wall of the heating box 71. The purpose is to make the heating box 71 heat evenly, so as to facilitate the heating of the liquid outlet pipe 6 and keep the temperature inside the liquid outlet pipe 6 consistent.

[0035] Optionally, the heating box 71 is located outside the outlet pipe 6. The length of the heating box 71 is the same as the length of the part of the outlet pipe 6 located outside the receiving tank 2. This allows for heating of various parts of the outlet pipe 6, thereby maintaining a consistent temperature inside the outlet pipe 6 and preventing the electrolyte raw material from crystallizing in a certain place, which would affect the transportation of the electrolyte raw material.

[0036] Optionally, both the storage tank 1 and the receiving tank 2 are provided with two support legs on their exteriors. The two support legs are symmetrical about the center of the storage tank 1 and the receiving tank 2, respectively. The purpose of this is to support the storage tank 1 and the receiving tank 2 so that the storage tank 1 and the receiving tank 2 do not come into contact with the ground, thereby preventing the ground temperature from being transferred to the storage tank 1 and the receiving tank 2, thus reducing the impact of the external environment on the crystallization of the electrolyte raw materials.

[0037] Optionally, the temperature regulating component 74 is electrically connected to the heating wire 72, the heating plate 73, and the vacuum pump 75, thereby achieving the purpose of regulating the temperature inside the heating chamber 71. When the temperature inside the heating chamber 71 is too high, the vacuum pump 75 can evacuate the air inside the heating chamber 71, thus ensuring that the temperature inside the heating chamber 71 is maintained at a suitable level.

[0038] Working principle: When it is necessary to transfer electrolyte raw materials, the temperature regulation component 74 is first activated. The temperature regulation component 74 energizes the heating plate 73 and the heating wire 72, thereby regulating the temperature inside the heating box 71 so that the temperature inside the heating box 71 is higher than the crystallization temperature of the electrolyte raw materials. When the temperature reaches the set value, the temperature regulation component 74 is turned off, and the liquid pump 4 is activated. The liquid pump 4 draws the electrolyte raw materials from the storage tank 1 into the receiving tank 2, thereby facilitating the transfer of electrolyte raw materials.
