[0017] Example 1

[0018] like Figures 1 to 4 As shown, the present invention proposes a fuel cell coolant mixing device, including a mixing tank 1, an adjusting mechanism, a stirring tube 6, and a stirring mechanism; a tank cover 2 is detachably installed on the top of the mixing tank 1; the adjusting mechanism is installed on the top of the tank cover 2, and a first housing 4 and a second housing 5 are installed on the adjusting mechanism. The first housing 4 and the second housing 5 are reciprocally adjusted towards or away from each other along the height direction of the mixing tank 1 by the driving of the adjusting mechanism; the stirring tube 6 is rotatably connected to the second housing 5, and the stirring tube 6 is set through the tank cover 2. The tank cover 2 has a through hole 201 corresponding to the stirring tube 6, and the diameter of the through hole 201 is larger than the outer diameter of the stirring tube 6. A stirring rod 7 is installed through the inside of the stirring tube 6, and the stirring rod 7 is rotatably connected to the first housing 4. The stirring tube 6 and the stirring rod 7 rotate in opposite directions. Both the first housing 4 and the second housing 5 are provided with driving components, and the stirring tube 6 and the stirring rod 7 are driven to rotate by the corresponding driving components; two sets of stirring mechanisms are provided, and the two sets of stirring mechanisms are respectively installed at the bottom of the stirring tube 6 and the stirring rod 7.

[0019] Furthermore, the lid 2 is abutted to the top of the mixing tank 1. Two sets of limiting blocks are symmetrically arranged inside the top of the lid 2. The outer walls of the two sets of limiting blocks are slidably connected to the inner wall of the mixing tank 1, which facilitates the quick alignment of the lid 2 with the mixing tank 1 and the adjustment of each set of threaded rods 202. Multiple sets of threaded rods 202 are symmetrically threaded on the lid 2. Abutting seats 203 are installed on the threaded rods 202. The abutting seats 203 are abutted to the side wall of the mixing tank 1. The abutting end of the abutting seat 203 is provided with an anti-slip pad to increase the friction at the connection with the mixing tank 1 and prevent the lid 2 from easily falling off the mixing tank 1.

[0020] Furthermore, the adjustment mechanism includes a bracket 3, a bidirectional threaded rod 301, a guide rod 302, and a movable seat 303; the bracket 3 is installed on the top of the bucket lid 2; the bidirectional threaded rod 301 is driven to rotate by a motor installed on the bracket 3, and the bottom end of the bidirectional threaded rod 301 is rotatably connected to the bucket lid 2; the guide rod 302 is installed between the other end of the bracket 3 and the bucket lid 2; four sets of movable seats 303 are provided, with two sets of movable seats 303 symmetrically arranged on the first housing 4 and the second housing 5, and the two sets of movable seats 303 located on the same side of the first housing 4 and the second housing 5 are symmetrically threadedly connected to the bidirectional threaded rod 301, and the other two sets of movable seats 303 are slidably connected to the guide rod 302.

[0021] Furthermore, the drive assembly consists of a gear ring 8 installed on the outer wall of the stirring tube 6 or the stirring rod 7 and a gear 801 meshing with the gear ring 8. The gear 801 is driven to rotate by a motor installed inside the first housing 4 or the second housing 5.

[0022] In this embodiment, the lid 2 is placed on top of the mixing tank 1 and abuts against it, and two sets of limiting blocks are slidably inserted into the mixing tank 1. The threaded rod 202 is rotated until the abutment seat 203 abuts against the side wall of the mixing tank 1. Then, the lid 2 and the mixing tank 1 are stably connected by the threaded rods 202 and the abutment seat 203. At this time, the two stirring mechanisms are located inside the mixing tank 1. The raw materials used for processing fuel cell coolant are poured into the mixing tank 1 through the feed pipe on the lid 2 in a certain proportion. At the same time, the controller starts the motor to drive the gear 801 to rotate, which in turn drives the gear ring 8 to rotate. This causes the stirring tube 6 installed on the gear ring 8 to rotate along the second housing 5, which drives the stirring rod 7 to rotate along the first housing 4. The stirring rod 7 and the stirring tube 6 rotate in opposite directions, so that the upper and lower parts of the raw materials inside the mixing tank 1 are stirred by the two stirring mechanisms.

[0023] The controller starts the motor to rotate clockwise and counterclockwise alternately, which in turn drives the bidirectional threaded rod 301 to rotate clockwise and counterclockwise an appropriate number of times. Under the guidance of the guide rod 302, the first housing 4 and the second housing 5 move closer or further apart through the moving seats 303. This causes the stirring tube 6 to move back and forth along the barrel cover 2 and the stirring rod 7 along the vertical direction of the stirring tube 6. This causes the stirring mechanism on the stirring tube 6 and the stirring mechanism on the stirring rod 7 to move closer or further apart vertically, thereby thoroughly stirring the raw materials inside the mixing barrel 1, shortening the stirring time, making the raw materials mix quickly, and improving the mixing efficiency.

[0024] Example 2

[0025] like Figure 2As shown, the fuel cell coolant mixing device proposed in this utility model, compared with Embodiment 1, has a stirring mechanism consisting of a first stirring blade 9 and a second stirring blade 901. Both the second stirring blade 901 and the first stirring blade 9 have multiple sets of turbulence holes with different diameters, which improves the mixing efficiency of fuel cell coolant raw materials.

[0026] Furthermore, the first stirring blade 9 and the second stirring blade 901 have different lengths, and the first stirring blade 9 and the second stirring blade 901 have different installation heights relative to the stirring tube 6 or the stirring rod 7, which facilitates the full mixing of raw materials at different positions inside the mixing tank 1.

[0027] In this embodiment, the first stirring blade 9 and the second stirring blade 901 are of different lengths, which can stir the raw materials at different horizontal positions inside the mixing tank 1. The first stirring blade 9 and the second stirring blade 901 are installed at different heights, which facilitates stirring of raw materials at different heights inside the mixing tank 1, making the raw materials more thoroughly mixed and further improving the mixing efficiency.

[0028] 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.
