[0046] Working principle:

[0047] During use, the antioxidant is added through the feeding port on the mixing tank 1, and other solid antioxidant particles to be mixed are placed in the storage box 4 through the feeding box 3. The added solid antioxidant particles are guided by the guide plate 12 and fall onto the feeding roller 13, which is in close contact with the guide plate 12. At this time, the servo motor 5 is started, and its output shaft drives the feeding roller 13 to rotate. During the rotation of the feeding roller 13, the solid antioxidant particles in the grooves on it will fall into the mixing tank 1 for mixing due to gravity. During the rotation of the feeding roller 13, the right-angle gear 16 fixed on it will drive the transmission belt 11 connected to it to rotate simultaneously. During the rotation of the transmission belt 11, it will drive the two right-angle gears 15 to rotate simultaneously. At this time, the two crushing rollers 14 also rotate. During the rotation of the two crushing rollers 14, the solid antioxidant particles will be crushed, so that the added solid antioxidants are mixed. The more uniform particle size of the antioxidant allows for better integration with the liquid antioxidant. Furthermore, the pulverized antioxidant has a larger specific surface area, enabling it to more quickly capture reactive oxygen species in biodiesel, thus more effectively inhibiting oxidation and extending the storage time of biodiesel. During the mixing process, the output shaft of the servo motor 2 drives the fixed stirring rod 10 to rotate. The rotation of the stirring rod 10 drives the fixed right-angle gear 9 to rotate, which in turn drives the meshing right-angle gear 9 to rotate simultaneously. The driven right-angle gear 9, in turn, drives the inner tank 6, which is engaged with it, to rotate. At this time, the inner tank 6 and the stirring rod 10 rotate in opposite directions. This relative motion causes the biodiesel and antioxidant to be repeatedly stretched, folded, and sheared under different rotational directions, resulting in a finer and more uniform mixture and improving mixing efficiency.

[0048] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
