[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0036] Reference Figures 1 to 3The stirring structure of the first aspect of this utility model includes a central shaft 100, an outer spiral assembly 200, and an inner spiral assembly 300. A radially extending first mounting shaft 110 is mounted on the central shaft 100. The outer spiral assembly 200 and the inner spiral assembly 300 are both sleeved on the outer periphery of the central shaft 100 and are both connected to the first mounting shaft 110. See details below. Figure 1 As shown, the outer spiral assembly 200 is spirally arranged along the axial direction of the central shaft 100 and connected to the end of the first mounting shaft 110; the inner spiral assembly 300 is also spirally arranged along the axial direction of the central shaft 100, and is positioned between the outer spiral assembly 200 and the central shaft 100, connected to the middle of the first mounting shaft 110. The spiral structure of the outer spiral assembly 200 and the inner spiral assembly 300 enhances the turbulence capability of the stirring structure, while ensuring that the raw materials at each location are fully stirred. This achieves thorough mixing of the raw materials, improves the mixing efficiency, and consequently increases the production efficiency of silicone oil.

[0037] Furthermore, referring to Figure 1 As shown, the outer spiral assembly 200 includes two first spirals 210 that are rotationally symmetrical about the central axis 100, and the inner spiral assembly 300 includes two second spirals 310 that are rotationally symmetrical about the central axis 100. The rotational symmetry angle of the two first spirals 210 is 180°, and / or the rotational symmetry angle of the two second spirals 310 is 180°. Preferably, the rotational symmetry angles of the two first spirals 210 and the two second spirals 310 are both 180°, and the first spirals 210 and the second spirals 310 are offset by 90° to achieve a better turbulence effect.

[0038] In the embodiments of this application, it is further preferred that the first helix 210 and the second helix 310 rotate in opposite directions, so as to Figure 1 For example, if the rotation direction of the first helix 210 is defined as clockwise, then the rotation direction of the second helix 310 is counterclockwise. That is, if the initial rotation angle of one of the first helixes 210 is defined as 0° and the clockwise rotation angle as a positive value, then the initial rotation angle of the other first helix 210 is 180°; correspondingly, if the initial rotation angle of one of the second helixes 310 is defined as 0°, then the initial rotation angle of the other second helix 310 is -180°. The rotationally symmetrical first helix 210 and second helix 310 increase the structural density of the stirring structure, thereby improving the turbulence effect of the stirring structure.

[0039] In the embodiments of this application, along the axial direction of the central axis 100, the outer diameter of the outer spiral assembly 200 remains unchanged, and / or, the outer diameter of the inner spiral assembly 300 remains unchanged. Specifically, refer to... Figure 1 , Figure 3As shown, it is preferable that both the first helix 210 and the second helix 310 are equal diameter helices, which can effectively reduce manufacturing and maintenance costs.

[0040] It is conceivable that in actual production, the outer diameters of the outer spiral assembly 200 and the inner spiral assembly 300 can be designed according to requirements. For example, the outer diameter of the first spiral 210 can gradually increase or decrease along the axial direction of the central axis 100. The gradual increase or decrease can be linear or non-linear. Alternatively, the outer diameter of the first spiral 210 can be increased and then decreased, or decreased and then increased, etc., along the axial direction of the central axis 100. Similarly, the outer diameter of the second spiral 310 can also increase or decrease along the axial direction of the central axis 100. The specific application can be set according to actual needs and is not limited in this embodiment.

[0041] To further reduce manufacturing and maintenance costs, the first spiral 210 and the second spiral 310 can use the same spiral, for example, the thickness, width and other data of the first spiral 210 and the second spiral 310 can be designed to be equal.

[0042] It should be noted that, referring to Figure 3 As shown, in this embodiment, the outer diameter D1 of the outer spiral assembly 200 and the outer diameter D2 of the inner spiral assembly 300 are preferably related as follows: D2 = 0.3~0.7D1, so as to avoid the outer spiral assembly 200 and the inner spiral assembly 300 being too close or too far apart, which would reduce the mixing effect on the raw materials.

[0043] In the embodiments of this application, reference is made to Figure 1 , Figure 2 As shown, the central shaft 100 is also equipped with a radially extending second mounting shaft 120. The first mounting shaft 110 and the second mounting shaft 120 are staggered along the axial direction of the central shaft 100; the outer spiral assembly 200 and the inner spiral assembly 300 are both connected to the second mounting shaft 120. Specifically, the axial extension direction of the second mounting shaft 120 is perpendicular to the axial extension direction of the first mounting shaft 110, and refers to... Figure 2 As shown, the axial length of the second mounting shaft 120 is basically equal to the axial length of the first mounting shaft 110, and the shape and size of the second mounting shaft 120 are also basically the same as those of the first mounting shaft 110. The outer spiral assembly 200 is connected to the end of the second mounting shaft 120, and the inner spiral assembly 300 is connected to the middle of the second mounting shaft 120, so as to reduce the manufacturing cost of the stirring structure.

[0044] It is conceivable that the axial extension direction of the second mounting shaft 120 is not limited to being perpendicular to the axial extension direction of the first mounting shaft 110; the included angle between them can also be an acute or obtuse angle. The second mounting shaft 120 enhances the stability of the first helix 210 and the second helix 310, reduces the deformation of the first helix 210 and the second helix 310 during the stirring process in this embodiment, and thus extends the service life of the stirring structure.

[0045] Reference Figure 1 As shown, the first mounting shaft 110 passes through the central shaft 100, and its middle portion is welded to the central shaft 100. Both ends of the first mounting shaft 110 are connected to two first helices 210, respectively. For ease of understanding, using the central shaft 100 as a boundary, the two ends of the first mounting shaft 110 extending beyond the central shaft 100 are defined as the first shaft segment and the second shaft segment, respectively. The two second helices 310 are connected to the middle portions of the first and second shaft segments, respectively. Correspondingly, the second mounting shaft 120 also passes through the central shaft 100, and its middle portion is welded to the central shaft 100. Both ends of the second mounting shaft 120 are connected to two first helices 210, respectively.

[0046] In the embodiments of this application, multiple first mounting shafts 110 are provided, and the multiple first mounting shafts 110 are evenly spaced along the axial direction of the central shaft 100; and / or, multiple second mounting shafts 120 are provided, and the multiple second mounting shafts 120 are evenly spaced along the axial direction of the central shaft 100. Specifically, refer to... Figure 1 , Figure 2 As shown, multiple first mounting shafts 110 and second mounting shafts 120 can significantly improve the fixing effect on the first helix 210 and the second helix 310, thereby improving the stability of the stirring structure in this embodiment, enhancing the turbulence effect, and extending the service life of the equipment.

[0047] According to a second aspect embodiment of the present invention, a silicone oil mixing vessel is provided with a cavity for containing raw materials. The aforementioned stirring structure is installed within the cavity to stir and mix various raw materials, thereby producing silicone oil that meets the requirements. Since the silicone oil mixing vessel includes the aforementioned stirring structure, it possesses at least all the beneficial effects of a stirring structure, which will not be elaborated upon here.
