[0038] Example 1

[0039] like Figure 1-3 As shown, the present invention proposes a fuel cell coolant mixing device, which includes a discharge valve 4, a bellows 6, a motor 9, a cylinder, a stirring assembly, and a mixing tank.

[0040] There are multiple ingredient tanks, all of which are installed on the top of the cylinder. Weighing components are provided on both sides of the bottom of the ingredient tanks for supporting and weighing them during use.

[0041] The stirring assembly is rotatably installed inside the cylinder along the length of the cylinder body, and one end extends to the outside of the cylinder body 1; the motor 9 is located on the outside of the cylinder body 1 and is connected to the stirring assembly for transmission.

[0042] The bellows 6 is set between the cylinder and the mixing tank, and its two ends are connected to the cylinder and the mixing tank respectively. It is used to connect the mixing tank and the cylinder through the bellows 6 during use, and to enable the mixing tank to move up and down in the weighing component, so as to avoid the mixing tank being unable to perform weight measurement work due to direct connection with the cylinder.

[0043] The discharge valve 4 is installed at the bottom middle of the cylinder and is connected to the cylinder. It is used to discharge the prepared coolant in the cylinder during use.

[0044] In this embodiment, raw materials are transported to the mixing tank through an external conveying pipe. At the same time, the weighing component weighs the mixing tank and transports the raw materials to the inside of the cylinder through the corrugated pipe 6. Simultaneously, the motor 9 is started, causing the motor 9 to drive the stirring component to rotate inside the cylinder. The stirring component also causes the raw materials inside the cylinder to move back and forth along the length of the cylinder, mixing the various raw materials and making the mixture more uniform. Since there are multiple mixing tanks, and each mixing tank has a weighing component for weighing, multiple raw materials are weighed simultaneously. The weight is detected and transported to the cylinder through the corrugated pipe 6, improving the efficiency of coolant mixing.

[0045] Example 2

[0046] like Figure 1-2 As shown, the present invention proposes a fuel cell coolant mixing device. Compared with the first embodiment, the difference in this embodiment is that the cylinder includes a cylinder body 1, a hinge bolt 2, and a cover plate 3.

[0047] The cylinder body 1 has a cavity with an opening at the top in the middle, and the bottom projection shape of the cavity is semi-circular.

[0048] The cover plate 3 is placed on the top of the cylindrical body 1, and the edge of the cover plate 3 coincides with the top edge of the cylindrical body 1, which is used to seal the cavity of the cylindrical body 1 during use.

[0049] There are multiple hinge bolts 2, all of which are installed on the outside of the cylinder body 1 and near the top end and connected to the cover plate 3. They are used to rotate upward or downward during use so that the cover plate 3 is fixed to the top end of the cylinder body 1 or separated from the cylinder body 1.

[0050] In this embodiment, the raw material is cooled by the cavity of the cylinder body 1, and the stirring assembly stirs the raw material efficiently in the cavity. At the same time, the cover plate 3 is fixed to the top of the cylinder body 1 by the hinge bolt 2, so that the cover plate 3 closes the top of the cylinder body 1, forming a sealed space in the cavity of the cylinder body 1. This ensures that the raw material does not leak out during the stirring process, makes it easy to clean the inner wall of the cavity of the cylinder body 1, and makes it convenient to disassemble and maintain the stirring assembly.

[0051] Example 3

[0052] like Figure 1 As shown, the present invention proposes a fuel cell coolant mixing device. Compared with the first embodiment, the difference in this embodiment is that the mixing tank includes an electric valve 7, a tank body 10 connecting seat 11, and a feeding port 19.

[0053] The tank body 10 is positioned above the cover plate 3, and has a cavity in the middle and a conical bottom.

[0054] The electric valve 7 is installed at the bottom of the tank body 10 and the bottom is connected to the bellows 6;

[0055] The number of connecting seats 11 is at least two. The two connecting seats 11 are arranged at equal angles to the outside of the tank body 10 according to the center of the tank body 10. The connecting seats 11 are installed on the top of the weighing assembly.

[0056] The feed inlet 19 is connected to the tank body 10 for connecting with an external raw material conveying device to convey raw materials into the tank body 10.

[0057] In this embodiment, the raw materials are conveyed into the tank 10 through the feed inlet 19 connected to an external raw material conveying device, and connected to the weighing component through the connecting seat 11, so that the weighing component can monitor the weight of the tank 10 through the connecting seat 11. At the same time, the electric valve 7 is opened to convey the raw materials in the tank 10 to the cavity of the cylinder body 1 through the corrugated pipe 6, so as to realize the accurate addition of raw materials and improve the proportioning accuracy.

[0058] Example 4

[0059] like Figure 3 As shown, the present invention proposes a fuel cell coolant mixing device. Compared with the first embodiment, the difference in this embodiment is that the weighing component includes a support column 5, a mounting plate 17, and a weighing sensor 18.

[0060] The support column 5 is installed on the top of the cover plate 3;

[0061] Mounting plate 17 is installed on the top of support column 5;

[0062] The load cell 18 is mounted on the top center of the mounting plate 17 and connected to the connector 11.

[0063] In an optional embodiment, the mounting plate 17 has a U-shaped projection and wraps around both sides of the connector 11.

[0064] In an optional embodiment, slide rails 16 are provided on both inner walls of the mounting plate 17, and slide bars 15 are provided on both sides of the connecting seat 11. When the connecting seat 11 and the mounting plate 17 are installed together, the slide bars 15 are accommodated in the slide rails 16.

[0065] In this embodiment, by installing a support column 5 at the top of the cover plate 3, and stacking the mounting plate 17 and the weighing sensor 18 on the top of the support column 5, and by placing the connecting seat 11 on the top of the weighing sensor 18, the weighing sensor 18 can monitor the weight of the raw material inside the tank 10 in real time through the connecting seat 11. At the same time, the position of the connecting seat 11 is limited by the shape of the mounting plate 17 and the cooperation between the slide bar 15 and the slide rail 16, thereby limiting the position of the tank 10 and preventing the tank 10 from shifting during use.

[0066] Example 5

[0067] like Figure 2 As shown, the present invention proposes a fuel cell coolant mixing device. Compared with Embodiment 1, this embodiment differs in that the stirring assembly includes a rotating shaft 8, a connecting rod 12, a first spiral plate 13, and a second spiral plate 14; the rotating shaft 8 penetrates the cylindrical body 1.

[0068] The rotating shaft 8 is rotatably installed inside the cylinder body 1, with one end extending outward from one end of the cylinder body 1 and connected to the motor 9 for transmission.

[0069] There are multiple connecting rods 12, and all of the multiple connecting rods 12 are installed on the outside of the rotating shaft 8 and located on the inside of the cylinder body 1;

[0070] There are two first spiral plates 13. The two first spiral plates 13 are arranged symmetrically at the end of the connecting rod 12 and located on the inner wall of the cylinder body 1 according to the center of the cylinder body 1.

[0071] There are two second spiral plates 14, which are arranged symmetrically with respect to the center of the cylinder body 1 at the middle of the connecting rod 12 and located inside the first spiral plate 13.

[0072] In an optional embodiment, the first spiral plate 13 and the second spiral plate 14 are arranged in opposite spiral directions. During use, the first spiral plate 13 drives the liquid on the inner wall of the cylinder body 1 to move towards the middle or end of the cylinder body 1, and the second spiral plate 14 drives the liquid on the inner side of the first spiral plate 13 to move towards the end or middle of the cylinder body 1. When the first spiral plate 13 and the second spiral plate 14 rotate in the same direction, the liquid is driven to move in layers, thereby improving the mixing effect and uniformity of the coolant raw materials.

[0073] In this embodiment, the rotating shaft 8 is driven to rotate by the motor 9. The rotating shaft 8 drives the first spiral plate 13 and the second spiral plate 14 to rotate synchronously through the connecting rod 12. The first spiral plate 13 and the second spiral plate 14 are arranged in opposite spiral directions to form a highly efficient stirring flow field, ensuring uniform mixing of the coolant. At the same time, the symmetrical arrangement of the two first spiral plates 13 and the second spiral plate 14 further optimizes the stirring effect and moves the liquid towards the middle of the cylinder body 1, making it more efficient for the cylinder body 1 to discharge the liquid through the discharge valve 4.

[0074] In this invention, the raw materials are fed into the tank 10 through the feed inlet 19 connected to an external raw material conveying device. Simultaneously, the weighing sensor 18 weighs the raw materials inside the tank 10 via the connecting seat 11, ensuring that the raw materials are dispensed as needed, avoiding over- or under-dispensing. By opening the electric valve 7, the raw materials in the tank 10 are conveyed to the cavity of the cylinder body 1 through the bellows 6, achieving precise control. Simultaneously, the motor 9 drives the rotating shaft 8 to rotate, which in turn drives the first spiral plate 13 and the second spiral plate 14 to rotate synchronously via the connecting rod 12. The first spiral plate 13 and the second spiral plate 14 are arranged with opposite spiral directions, forming a high-speed... The system effectively stirs the flow field, ensuring uniform mixing of the coolant. Simultaneously, the symmetrical arrangement of the two first spiral plates 13 and the second spiral plate 14 further optimizes the stirring effect, causing the liquid to move towards the center of the cylinder body 1. This allows the cylinder body 1 to efficiently discharge the liquid through the discharge valve 4. The cover plate 3 is fixed to the top of the cylinder body 1 using the hinge bolt 2, closing the top of the cylinder body 1 and creating a sealed space within the cavity. This ensures that the raw materials do not leak during stirring, facilitates cleaning of the inner wall of the cylinder body 1's cavity, and makes the disassembly and maintenance of the connecting rod 12, the first spiral plate 13, and the second spiral plate 14 more convenient.

[0075] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
