An electrolytic fluorine production stirring device includes an electrolytic cell. The interior of the electrolytic cell includes an anode, a cathode, and a partition board. The partition board is located between the anode and the cathode. The electrolytic cell is divided into an anode area and a cathode area with the partition board as the dividing line.

One end of the air inlet pipe passes through the side wall of the electrolytic cell and is located in the cathode area, and the other end is connected to a high-pressure gas output device. This device uses high-pressure nitrogen gas to stir the electrolyte. The fluorine gas and hydrogen gas generated by electrolysis are mixed with nitrogen gas, which increases the subsequent process of removing nitrogen and reduces the overall production efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for preparing fluorine electrolyte for the above-mentioned existing technical problems, so as to fully stir the electrolyte and improve the electrolysis efficiency.

[0005] In view of this, the utility model provides a device for preparing fluorine electrolyte, including a base. An electrolytic box is arranged on the base. A feeding pipeline penetrates through the top wall of the electrolytic box. Air outlet pipelines are arranged on both sides of the feeding pipeline. The air outlet pipelines penetrate through the top wall of the electrolytic box. An electrolysis component is arranged inside the electrolytic box. It further includes: The stirring component includes a first motor. The first motor is fixedly arranged on the base. The first motor is transmission-connected with a stirring unit. The stirring unit is arranged inside the electrolytic box.

[0006] In this technical solution, the electrolysis component includes an anode electrolytic rod, a cathode electrolytic rod, and a partition board. The partition board is arranged between the anode electrolytic rod and the cathode electrolytic rod. The electrolyte enters the electrolytic box through the feeding pipeline. When appropriate electrolyte is added, the electrolyte is stirred by the stirring component. After stirring is completed, electrolysis is carried out by the electrolysis component. Since the electrolyte is composed of two or more chemical reagents, it is fully stirred and mixed by the stirring component to improve the electrolysis efficiency.

[0007] In the above technical solution, further, the stirring unit includes a first stirring paddle, the first stirring paddle is rotatably arranged below the partition plate, the first stirring paddle pushes the electrolyte to both sides, and two second stirring paddles are rotatably arranged on both sides of the first stirring paddle.

[0008] In the above technical solution, further, the stirring assembly further includes a first roller, a second roller and a third roller.

Belt pulleys are coaxially and fixedly arranged on the first roller, the second roller and the third roller, and transmission belts are connected between two adjacent and close belt pulleys.

[0009] In this technical solution, the first motor rotates to drive the belt pulley to rotate. Through the transmission of the transmission belt, all the belt pulleys rotate, and the belt pulley drives the first stirring paddle and the second stirring paddle to rotate. The first stirring paddle stirs the electrolyte under the partition plate and pushes it to both sides of the anode electrolysis rod and the cathode electrolysis rod. The second stirring paddle stirs the electrolyte pushed by the first stirring paddle, so as to fully stir the electrolyte in the tank.

[0010] In the above technical solution, further, a reflux structure is further included. The reflux structure is arranged in the air outlet pipe, and the reflux structure is connected with a condensation assembly, and the condensation assembly is arranged outside the electrolysis tank.

[0014] In the above technical solution, further, the overall shape of the first stirring paddle is S-shaped.

[0015] In this technical solution, when the first stirring paddle rotates, the overall S-shaped setting of the first stirring paddle can better push the electrolyte to both sides.

The liquefied hydrogen fluoride flows back into the electrolysis tank along the surface of the condensation reflux pipe. Description of the Drawings
