Description

Technical Field

[0001] This utility model relates to the field of battery production technology, specifically to a battery formation tank. Background Technology

[0002] In the formation process of batteries, cold water is typically injected into the formation tank through circulation pipes, while hot water generated during the reaction is discharged to achieve temperature control. Currently, the traditional cooling method for temperature control in formation tanks involves directly injecting cold water into one end of the tank and discharging hot water from the other. This crude heat exchange leads to significant temperature stratification within the tank. Specifically, the hot water in different areas forms temperature gradients due to insufficient diffusion rate of the cooling water, thus affecting the uniformity of simultaneous heat release from the battery group during the formation process. This non-uniform thermal environment not only reduces heat exchange efficiency but may also lead to differences in formation reaction rates between batteries, ultimately affecting overall process stability and equipment operating efficiency. Summary of the Invention

[0003] This invention addresses the problem of temperature gradients generated during cooling in formation tanks used to cool the heat of battery formation. It provides a battery formation tank that improves heat exchange efficiency, reduces temperature differences within the formation tank, and enhances the battery formation effect.

[0004] To solve the above problems, the technical solution of this utility model is:

[0005] A battery formation tank includes a tank body, a U-shaped plate, water supply components, and control components. The left and right ends of the U-shaped plate are respectively fixedly connected to the left and right side plates of the tank body, and there is a gap between the outer side of the U-shaped plate and the inner side of the tank body. Water supply components are symmetrically arranged at the front and rear of the U-shaped plate. The rear water supply component includes a horizontal pipe and a vertical pipe. The horizontal pipe is fixed to the rear of the outer bottom surface of the U-shaped plate, with an open left end and a closed right end. Multiple vertical pipes are fixed to the rear of the bottom plate of the U-shaped plate. The upper end of the vertical pipe is closed, and the lower end is connected to the horizontal pipe. The front end of the vertical pipe is provided with a water outlet. The control components include a second horizontal pipe and a water inlet pipe. The second horizontal pipe is fixed to the outer left side of the tank body. The left ends of the two first horizontal pipes are respectively connected to the front and rear of the second horizontal pipe. The middle of the second horizontal pipe is connected to the water inlet pipe. Valves are provided at both the front and rear ends of the second horizontal pipe. Each valve controls the closing or opening of the left end of the first horizontal pipe on the same side.

[0006] Furthermore, the front and rear side plates of the U-shaped plate are provided with multiple overflow holes at their upper parts; the multiple overflow holes on the same side are all lower than the upper end of the tank.

[0007] Furthermore, a drain pipe is connected to the peripheral wall of the tank, and there is a gap between the lower end of the two horizontal pipes and the bottom of the tank.

[0008] Furthermore, the valves at the front and rear ends of the second horizontal tube are symmetrical; the valve at the front includes a movable plate and a connecting rod. The movable plate is slidably disposed in the front part of the second horizontal tube. The front end of the movable plate is fixedly connected to the connecting rod. The front end of the connecting rod movably passes through the front end of the second horizontal tube. A spring is connected between the movable plate and the front end of the second horizontal tube.

[0009] Furthermore, the front end of the connecting rod of the valve on the front side is connected to a baffle, and the front end of the second horizontal tube is provided with an air outlet; when the spring of the valve on the front side is in its natural state, the movable plate on the valve is located behind the first horizontal tube on the front side; when the spring of the valve on the front side is compressed to its limit state, the movable plate on the valve is located in front of the first horizontal tube on the front side.

[0010] Furthermore, a pump body is provided on the water inlet pipe; when the springs on both valves are in their natural state, the distances from the movable plates on the two valves to the end where the water inlet pipe and the horizontal pipe are connected are equal.

[0011] The beneficial effects of this utility model through the above technical solution are as follows:

[0012] When the pump body is working, this utility model can introduce cooling water into the U-shaped plate to cool the battery formed in the U-shaped plate. Moreover, after the temperature of the cooling water in the U-shaped plate rises, the pump body drives the cooling water to inject water into the U-shaped plate, which neutralizes and cools the already heated cooling water in the U-shaped plate. Multiple vertical pipes on the same side are arranged at intervals from left to right, which can reduce the temperature gradient when the cooling water in the U-shaped plate is neutralized and cooled, and reduce the impact of temperature difference on the battery. Excess water can be discharged through the drain pipe. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1-5 As shown, a battery formation tank includes a tank body 1, which is a rectangular tank with an open top. It also includes a U-shaped plate 2, water supply components, and control components. The U-shaped plate 2 has open ends on its left and right sides and an open top. The left and right ends of the U-shaped plate 2 are respectively fixedly connected to the left and right side plates of the tank body 1. There is a gap between the outer surface of the U-shaped plate 2 and the inner surface of the tank body 1. Water supply components are symmetrically arranged at the front and rear of the U-shaped plate 2. The rear water supply component includes a horizontal pipe 3 and a vertical pipe 4. The horizontal pipe 3 is a circular tube and is fixed to the rear of the outer bottom surface of the U-shaped plate 2. The left end of the horizontal pipe 3 is open, and the right end is closed. The bottom plate of the U-shaped plate 2 is located behind... The unit is fixed with multiple vertical pipes 4, each of which is a circular tube. The multiple vertical pipes 4 are spaced apart along the length of the U-shaped plate 2. The upper end of the vertical pipe 4 is closed and the lower end is connected to the horizontal pipe 3. The front end of the vertical pipe 4 is provided with a water outlet 5, which is an elongated hole opened along the height of the vertical pipe 4. The control component includes a second horizontal pipe 6 and a water inlet pipe 7. The second horizontal pipe 6 is fixed to the left side of the tank 1. The left ends of the two first horizontal pipes 3 are respectively connected to the front and rear parts of the second horizontal pipe 6. The middle part of the second horizontal pipe 6 is connected to the water inlet pipe 7. Valves are provided at both the front and rear ends of the second horizontal pipe 6. Each valve controls the closing or opening of the left end of the first horizontal pipe 3 on the same side.

[0021] The front and rear side plates of the U-shaped plate 2 are provided with multiple overflow holes 8 at their upper parts, and the multiple overflow holes 8 on the same side are spaced apart along the length of the U-shaped plate 2; the overflow holes 8 are round holes; the multiple overflow holes 8 on the same side are all lower than the upper end of the tank body 1.

[0022] A drain pipe 9 is connected to the peripheral wall of the tank 1, and there is a gap between the lower ends of the two horizontal pipes 3 and the bottom of the tank 1.

[0023] Both ends of the horizontal tube 6 are sealed by sealing plates. The valves at the front and rear ends of the horizontal tube 6 are symmetrical. The front valve includes a movable plate 10 and a connecting rod 11. The movable plate 10 is slidably disposed in the front part of the horizontal tube 6. The movable plate 10 is a circular plate that slides in contact with the inner wall of the horizontal tube 6. The front end of the movable plate 10 is fixedly connected to the connecting rod 11. The front end of the connecting rod 11 moves through the front end of the horizontal tube 6. A spring 12 is connected between the movable plate 10 and the front end of the horizontal tube 6. The spring 12 is sleeved on the outside of the connecting rod 11 between the movable plate 10 and the front end of the horizontal tube 6.

[0024] The front end of the connecting rod 11 of the valve on the front side is connected to a baffle 13, and the front end of the horizontal tube 6 is provided with an air outlet 14; when the spring 12 of the valve on the front side is in its natural state, the movable plate 10 on the valve is located behind the front horizontal tube 3; when the spring 12 of the valve on the front side is compressed to its limit state, the movable plate 10 on the valve is located in front of the front horizontal tube 3.

[0025] The water inlet pipe 7 is equipped with a pump body 15, which is fixed on the tank. When the springs 12 on both valves are in their natural state, the distance from the movable plate 10 on both valves to the end of the water inlet pipe 7 that connects to the horizontal pipe 6 is equal.

[0026] In the initial state, the springs on both valves are in the unloaded state, and the left openings of both horizontal pipes are blocked.

[0027] In use, multiple batteries to be formed are placed inside the U-shaped plate 2. The pump body 15 is activated, driving the cooling water in the inlet pipe 7 into the horizontal pipe 2 6. The pressure of the cooling water in the horizontal pipe 2 6 gradually increases, and the cooling water in the horizontal pipe 2 drives the movable plate 10 of the front valve forward until the movable plate 10 of the front valve moves to the front left end of the front horizontal pipe 3. Similarly, the movable plate 10 of the rear valve is pushed backward by the cooling water to the rear left end of the rear horizontal pipe 3. The left end openings of both horizontal pipes 3 are opened. Cooling water is introduced into both horizontal pipes 3. The cooling water in the horizontal pipe 3 flows upward into the vertical pipe 4 connected on the same side. The cooling water in the vertical pipe 4 enters the U-shaped plate 2 through the water outlet 5 on the vertical pipe 4. When the cooling water level in the U-shaped plate 2 is close to the overflow hole 8, the pump body 15 is closed. At this time, the pump body 15 no longer applies pressure to the horizontal pipe 6. The spring 12 on each valve of the horizontal pipe 6 returns to its initial state under its own restoring force. The left end openings of the two horizontal pipes 3 are blocked. Then, when the battery in the U-shaped plate is undergoing the formation process, the cooling water absorbs the heat of the battery formation.

[0028] When the cooling water temperature inside the U-shaped plate 2 rises to the point where it needs to be cooled down, the pump body 15 is restarted to supply cooling water into the horizontal pipe 2 6. As can be seen from the above process, during the process of the pump body 15 supplying cooling water into the horizontal pipe 2 6, cooling water is input into the two horizontal pipes 1 3, and multiple vertical pipes 4 connected to each horizontal pipe 1 3 supply cooling water into the U-shaped plate. Cooling water is simultaneously filled into the U-shaped plate from left to right. The cooling water in the U-shaped plate that has already risen in temperature is neutralized and cooled down. Moreover, the multiple vertical pipes 4 on the same side are spaced apart from left to right, which can reduce the temperature gradient when the cooling water in the U-shaped plate is neutralized and cooled down, and reduce the impact on the temperature difference of the battery. When multiple vertical pipes 4 fill the U-shaped plate with cooling water, the water level in the U-shaped plate rises. The water in the U-shaped plate that rises flows out through the overflow hole 8 and enters the tank 1. The water in the tank 1 is discharged through the drain pipe. When the cooling water temperature in the U-shaped plate drops, the pump body 15 is turned off, and the left ends of the two horizontal pipes 1 3 are blocked again.

[0029] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
