Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, specifically to a circulating cooling temperature-controlled slurry buffer device. Background Technology

[0002] The slurry preparation process is a crucial step in lithium-ion battery production. Slurry preparation involves mixing powdered positive and negative electrode active materials with specialized solvents and binders, then stirring at high speed to create a slurry-like mixture. A uniform slurry ensures the even distribution of the positive and negative electrodes on the substrate, thereby improving the consistency and safety of the battery cell. The slurry preparation process requires stable viscosity and prevents self-aggregation within the slurry.

[0003] Currently, the slurry pipeline of the mini coating machine is far from the factory building and lacks the function of controlling the slurry temperature. A slurry buffer tank is used to store the slurry in the coating process. The slurry buffer tank needs to detect and control the liquid level and precisely control the slurry temperature. Existing slurry buffer tanks are placed in a cooling water pool or cooled by cooling coils on the outside of the slurry buffer tank, which cannot accurately control the slurry temperature. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a circulating cooling temperature-controlled slurry buffer device. The device uses a temperature sensor to contact the slurry and monitors the slurry temperature in real time. It also uses a sandwich-structured buffer tank and cooling pipes inside the buffer tank to control the slurry temperature, thereby achieving precise control of the slurry temperature.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A circulating cooling and temperature-controlled slurry buffer device includes a buffer tank. The buffer tank is equipped with a slurry inlet pipe, a slurry outlet pipe, and a stirring assembly. The tank wall has a double-layer structure with a cooling water circulation jacket. The cooling water circulation jacket is connected to a first water inlet and a first water outlet. A U-shaped water pipe is installed inside the buffer tank, and the U-shaped water pipe is connected to a second water inlet and a second water outlet at the top of the buffer tank. Both the first and second water inlets are connected to the water inlet pipe, which is used to supply cooling water. Both the first and second water outlets are connected to a return water pipe, which is used for cooling water recirculation. A temperature sensor is installed on the side wall of the buffer tank, and the temperature sensor penetrates the cooling water circulation jacket so that its probe is located inside the buffer tank. The temperature sensor is used to detect the temperature of the slurry inside the buffer tank.

[0007] As a further improvement to the above technical solution, the first water inlet is located at the bottom of the cooling water circulation jacket, and the first water outlet is located at the top of the cooling water circulation jacket.

[0008] As a further improvement to the above technical solution, quick connectors are used to connect the first and second water inlets to the water inlet pipe, as well as the first and second water outlets to the return water pipe.

[0009] As a further improvement to the above technical solution, angle seat valves are provided on both the inlet pipe and the return pipe, and the angle seat valves are electrically connected to the temperature sensor. When the slurry temperature detected by the temperature sensor is higher than the set temperature, the angle seat valves on both the inlet pipe and the return pipe are open. When the slurry temperature detected by the temperature sensor meets the set temperature, the angle seat valves on both the inlet pipe and the return pipe are closed. When the slurry temperature detected by the temperature sensor is lower than the set temperature, the angle seat valve on the inlet pipe is closed, and the angle seat valve on the return pipe is open.

[0010] As a further improvement to the above technical solution, both the inlet pipe and the return pipe are equipped with manual ball valves, which are used to control the cooling water flow rate.

[0011] As a further improvement to the above technical solution, the stirring assembly includes a motor, a coupling, and a stirring paddle. The motor and coupling are installed on the top of the buffer tank, and the stirring paddle is located inside the buffer tank and connected to the main shaft of the motor via the coupling.

[0012] As a further improvement to the above technical solution, the stirring paddle includes a stirring main shaft, a fixed sleeve, a first stirring blade, and a second stirring blade. One end of the stirring main shaft is connected to a coupling, and the other end is connected to the fixed sleeve. The first stirring blade is disposed on the fixed sleeve, and the second stirring blade is connected to the first stirring blade.

[0013] As a further improvement to the above technical solution, multiple U-shaped water pipes are provided, and all of the multiple U-shaped water pipes are staggered with the rotation path of the stirring paddle.

[0014] As a further improvement to the above technical solution, a liquid level sensor is provided on the top of the buffer tank, which is used to monitor the slurry level inside the buffer tank.

[0015] As a further improvement to the above technical solution, the circulating cooling temperature-controlled slurry buffer device also includes a feeding trolley, on which multiple buffer tanks are installed.

[0016] The beneficial effects of this utility model are:

[0017] Cooling water circulation is achieved through a cooling water circulation jacket in the tank wall and a U-shaped water pipe inside the tank, ensuring uniform cooling of the slurry and improving its compositional stability. A temperature sensor is located at the bottom of the tank, from which the slurry is discharged, thus increasing the accuracy of the slurry temperature measurement. This invention uses a temperature sensor to monitor the slurry temperature online and automatically adjusts the cooling water circulation, achieving precise temperature control while reducing energy loss, eliminating manual labor, and improving production efficiency.

Detailed Implementation

[0027] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / installations can use accessories such as screws and bolts, or can be directly connected by welding, bonding, etc. The various technical features in this utility model can be combined interactively without contradicting each other.

[0028] Reference Figures 1-5 This utility model provides a circulating cooling temperature-controlled slurry buffer device, including a buffer tank 100, an inlet pipe 200, and a return pipe 300. The buffer tank 100 is provided with a slurry inlet pipe 110, a slurry outlet pipe 120, and a stirring assembly 130. It can be understood that the slurry inlet pipe 110 is located at the upper part of the storage tank to facilitate the injection of slurry into the storage tank, and the slurry outlet pipe 120 is located at the bottom of the storage tank to facilitate the discharge of slurry. The stirring assembly 130 is used to stir the slurry.

[0029] In this embodiment, the buffer tank 100 includes a tank body 101 and a sealing cap 102. The tank body 101 has a double-layer structure, forming a cooling water circulation jacket 103. The cooling water circulation jacket 103 is connected to a first inlet 140 and a first outlet 190. The first inlet 140 is located at the bottom of the cooling water circulation jacket 103, and the first outlet 190 is located at the top of the cooling water circulation jacket 103. Cooling water is injected into the cooling water circulation jacket 103 from the first inlet 140 and then discharged from the first outlet 190, thereby realizing cooling water circulation.

[0030] In addition, a U-shaped water pipe 1100 is provided inside the buffer tank 100, and the U-shaped water pipe 1100 is connected to a second water inlet 150 and a second water outlet 160 on the sealing cover 102 at the top of the buffer tank 100. Cooling water is injected into the U-shaped water pipe 1100 from the second water inlet 150 and then discharged from the second water outlet 160 to realize cooling water circulation.

[0031] It is understood that the cooling water circulation of the cooling water circulation jacket 103 is located outside the slurry, while the cooling water circulation of the U-shaped water pipe 1100 is located inside the slurry. This can achieve uniform cooling of the slurry, thereby improving the stability of the slurry composition.

[0032] In the above embodiment, the first water inlet 140 and the second water inlet 150 are both connected to the water inlet pipe 200, which is connected to the water supply plant and is used to provide cooling water. The first water outlet 190 and the second water outlet 160 are both connected to the return water pipe 300, which is also connected to the water supply plant and is used for cooling water return, thereby realizing cooling water circulation.

[0033] Furthermore, the first water inlet 140 and the second water inlet 150 are connected to the water inlet pipe 200 by a quick connector 170, and the first water outlet 190 and the second water outlet 160 are also connected to the return water pipe 300 by a quick connector 170. The quick connector 170 facilitates the quick connection and disconnection of the water inlet and outlet pipes with the water inlet and outlet.

[0034] In this embodiment, a temperature sensor 180 is provided on the side wall of the tank 101. The temperature sensor 180 penetrates the cooling water circulation jacket 103 so that its probe is located inside the buffer tank 100. The temperature sensor 180 is used to detect the temperature of the slurry inside the buffer tank 100. In addition, angle seat valves 400 are provided on both the inlet pipe 200 and the return pipe 300, and the angle seat valves 400 are electrically connected to the temperature sensor 180.

[0035] Understandably, the slurry in the storage tank needs to be maintained within a certain temperature range according to production requirements. When the slurry temperature detected by the temperature sensor 180 is higher than the set temperature, the angle seat valves 400 on the inlet pipe 200 and the return pipe 300 are both opened. At this time, cooling water enters the cooling water circulation jacket 103 and the U-shaped water pipe 1100 to achieve cooling water circulation. Simultaneously, under the stirring of the agitator 133, the slurry is uniformly cooled down, reducing the slurry temperature to the set temperature range. When the temperature sensor 180 detects... When the measured slurry temperature reaches the set temperature range, the angle seat valves 400 on the inlet pipe 200 and the return pipe 300 are both closed, and the cooling water does not circulate, thus maintaining the temperature. When the slurry temperature detected by the temperature sensor 180 is lower than the set temperature, the angle seat valve 400 on the inlet pipe 200 is closed, and the angle seat valve 400 on the return pipe 300 is opened, allowing the cooling water to be discharged from the cooling water circulation jacket 103 and the U-shaped water pipe 1100. Without the cooling water absorbing heat, the slurry temperature gradually rises.

[0036] In this way, the temperature sensor 180 monitors the slurry temperature in real time, and the slurry temperature is automatically adjusted by opening and closing the angle seat valve 400, thereby achieving precise adjustment of the slurry temperature and improving production efficiency.

[0037] Among them, reference Figure 2 The temperature sensor 180 is located at the bottom of the storage tank 100, and the slurry is discharged from the slurry outlet pipe 120 at the bottom of the storage tank 100. This can increase the accuracy of the slurry temperature measurement results and ensure that the temperature of the slurry supplied to the coating machine accurately meets the requirements.

[0038] In some embodiments, both the inlet pipe 200 and the return pipe 300 are equipped with manual ball valves 500, which are used to manually control the cooling water flow rate to ensure the stability of the cooling water circulation.

[0039] In this embodiment, the stirring assembly 130 includes a motor 131, a coupling 132, and a stirring paddle 133. The motor 131 is a pneumatic motor. The motor 131 and the coupling 132 are mounted on the sealing cover 102 of the buffer tank 100. The stirring paddle 133 is located inside the buffer tank 100 and is connected to the main shaft of the motor 131 through the coupling 132. When the slurry is cooled down, the motor 131 drives the stirring paddle 133 to stir the slurry to achieve a heat dissipation effect. At the same time, it stirs the slurry in the buffer tank 100 to prevent the slurry from agglomerating.

[0040] Furthermore, two U-shaped water pipes 1100 are provided, and both U-shaped water pipes 1100 are offset from the rotation path of the stirring paddle 133. This can prevent the stirring paddle 133 from colliding with the U-shaped water pipes 1100 and ensure stable operation of the equipment.

[0041] In the preferred embodiment, refer to Figure 6 The stirring paddle 133 includes a stirring main shaft 1331, a fixed sleeve 1332, a first stirring blade, and a second stirring blade. One end of the stirring main shaft 1331 is connected to the main shaft of the motor 131 via a coupling 132, and the other end is connected to the fixed sleeve 1332. The fixed sleeve 1332 and the stirring main shaft 1331 are connected by an interference fit or a threaded connection. The first stirring blade is L-shaped, and two first stirring blades are symmetrically arranged on the fixed sleeve, forming an overall U-shaped structure. The second stirring blade is spiral-shaped, and two second stirring blades are connected between the two first stirring blades. Both second stirring blades are convex outward based on the stirring main shaft, thereby increasing the stirring range.

[0042] The device has two first stirring blades, labeled A1333 and B1334, and two second stirring blades, labeled A1335 and B1336. One end of the second stirring blade A1335 is connected to the upper part of the first stirring blade A1333, and the other end is connected to the middle part of the first stirring blade B1334. One end of the second stirring blade B1336 is connected to the middle part of the first stirring blade A1333, and the other end is connected to the upper part of the first stirring blade B1334. This forms an alternating stirring blade structure, which can improve the stirring effect and make the temperature of the slurry in the tank 101 more uniform.

[0043] Among them, reference Figure 7 The two U-shaped water pipes 1100 are located inside the two second stirring blades, which avoids the rotation path of the first stirring blade and the second stirring blade, thereby preventing the stirring paddle 133 from colliding with the U-shaped water pipes 1100.

[0044] In this embodiment, a liquid level sensor is provided on the sealing cover 102 at the top of the buffer tank 100. The liquid level sensor is used to monitor the slurry level inside the buffer tank 100 to prevent slurry overflow or the liquid level from being too low and affecting production.

[0045] In practical applications, a feeding trolley 600 can also be equipped, which has multiple buffer tanks 100 installed and fixed on it, making it convenient to move and transport slurry in the production workshop and improve production efficiency.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
