[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a stirring blade with an integrated design that enables bidirectional propulsion of the stirred material, allowing the stirred material to tumble up and down within the same horizontal plane.

[0004] The stirring blade according to the first aspect of the present invention includes:

[0005] It includes a fixed structure, a first flipping blade, a first connecting structure and a second flipping blade connected in sequence. The first flipping blade and the second flipping blade are located on both sides of the first connecting structure. The first flipping blade is set at an angle to the horizontal plane. An arc-shaped protrusion is provided on the side of the first flipping blade near the fixed structure. The rotational pushing surface of the first flipping blade is opposite to the rotational pushing surface of the second flipping blade.

[0006] According to some embodiments of the present invention, a second connecting structure is also included, wherein the lower end of the second connecting structure is connected to the first flipping blade, one side of the second connecting structure is connected to the fixing structure, and the other side of the second connecting structure is connected to the first connecting structure.

[0007] According to some embodiments of the present invention, the angle between the first flipping blade and the horizontal plane is between 30 and 60 degrees, and the angle between the second flipping blade and the horizontal plane is between 120 and 150 degrees.

[0008] According to some embodiments of the present invention, the first flipping blade is perpendicular to the second flipping blade.

[0009] According to some embodiments of the present invention, the fixing structure includes a connecting part and mounting parts located on both sides.

[0010] According to some embodiments of the present invention, the connecting part has an arc-shaped structure, and the first flipping blade is located on the outer protruding surface of the connecting part.

[0011] On the other hand, this utility model embodiment provides a stirring paddle, comprising:

[0012] At least two sets of the above-mentioned stirring blades are formed by the fixed structure arranged circumferentially.

[0013] On the other hand, this embodiment of the invention also provides a stirring device, comprising:

[0014] The aforementioned stirring paddle;

[0015] The vessel body;

[0016] A driving component is mounted on the top of the vessel body, and the driving end of the driving component extends into the interior of the vessel body;

[0034] 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. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "horizontal," "bottom," and "inner," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "several" means two or more.

[0036] In the description of this utility model, unless otherwise explicitly defined, the terms "setting", "installing", "connecting", "linking", etc. should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in combination with the specific content of the technical solution.

[0037] The following is for reference. Figures 1 to 3 The stirring blade according to an embodiment of the present invention is described.

[0038] refer to Figure 1 As shown, according to one embodiment of the present invention, a stirring blade includes a fixed structure 110, a first rotating blade 120, a first connecting structure 130, and a second rotating blade 140 connected in sequence. The first rotating blade 120 and the second rotating blade 140 are located on both sides of the first connecting structure 130. The first rotating blade 120 is set at an angle to the horizontal plane. An arc-shaped protrusion is provided on the side of the first rotating blade 120 near the fixed structure 110. The rotational pushing surface of the first rotating blade 120 is opposite to the rotational pushing surface of the second rotating blade 140.

[0039] refer to Figure 1 and Figure 2 As shown, when the stirring blade rotates clockwise, the first flipping blade 120 can push the stirred material to flip diagonally downwards, and the second flipping blade 140 can push the stirred material to flip diagonally upwards, so that the entire stirred material continuously rotates and flips up and down, effectively avoiding the generation of eddies that cause uneven mixing.

[0040] Understandably, the arc-shaped protrusion design is more in line with fluid dynamics, can better fit the fluid flow, and reduce the force during stirring. On the other hand, it can also reduce stress concentration. Furthermore, the arc-shaped protrusion design, which is closer to the fixed structure 110, makes the object more stable during rotation, reduces the influence of centrifugal force, and thus prevents the first flipping blade 120 from deforming.

[0041] It is understandable that the integrated design of the first flip blade 120 and the second flip blade 140 enables vertical flipping on the same horizontal level.

[0042] Understandably, the design of the first connecting structure 130 can stably provide a planar position for connecting the second flipping blade 120, making it less likely for the second flipping blade 120 to break and detach from the stirring blade 100 during the stirring process.

[0043] In some specific embodiments of this utility model, a second connecting structure 150 is also included. The lower end of the second connecting structure 150 is connected to the first flipping blade 120, one side of the second connecting structure 150 is connected to the fixing structure 110, and the other side of the second connecting structure 150 is connected to the first connecting structure 130.

[0044] refer to Figure 1 and Figure 2 As shown, in this embodiment, the right end of the second connecting structure 150 is connected to the first connecting structure 130, the left end is connected to the fixed structure 110, and the lower end of the second connecting structure 150 is connected to the first flipping blade 120. This can strengthen the connection between the first flipping blade 120 and the first connecting structure 130 and the fixed structure 110, improve the service life, and also push the stirred material to rotate and tumble horizontally during rotation.

[0045] In some specific embodiments of this utility model, the angle between the first flipping blade 120 and the horizontal plane is between 30 and 60 degrees, and the angle between the second flipping blade 140 and the horizontal plane is between 120 and 150 degrees.

[0046] refer to Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the first rotating blade 120 has an angle of 30 degrees with the horizontal plane, and the second rotating blade 140 has an angle of 150 degrees with the horizontal plane. It can be understood that within this angle range, there can be axial and radial flow splitting, resulting in good particle dispersion of the stirred material. Furthermore, the perpendicular design of the first rotating blade 120 and the second rotating blade 140 ensures that the pushing direction of the first rotating blade 120 is completely opposite to that of the second rotating blade 140, resulting in more thorough and balanced mixing.

[0047] In some specific embodiments of this utility model, the first flipping blade 120 is perpendicular to the second flipping blade 140.

[0048] In some specific embodiments of this utility model, the fixing structure 110 includes a connecting portion 111 and mounting portions 112 located on both sides. The connecting portion 111 has a through positioning hole 1111, the opening direction of which is the same as the setting direction of the first flipping blade 120. The mounting portions 112 are provided with a plurality of connecting holes 1121, and the plurality of fixing structures 110 can be connected to each other through the plurality of connecting holes 1121. The connecting portion 111 has an arc-shaped structure, and the first flipping blade 120 is located on the outer protruding surface of the connecting portion 111.

[0049] refer to Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the design of the positioning hole 111 enables the stirring blade 100 to be better positioned and installed at a higher height, and the design of several connecting holes 1121 enables several fixed structures 110 to be interconnected around a central axis. The arc-shaped structure of the connecting part 111 enables the stirring blade 100 to be driven to rotate more evenly and is compatible with the cylindrical stirring shaft structure commonly used in the prior art.

[0050] This utility model embodiment also discloses a stirring paddle, which is described below with reference to... Figure 4 The description of the stirring blade according to an embodiment of the present utility model includes at least two sets of the above-described stirring blades, which are formed by a fixing structure 110 arranged circumferentially.

[0051] This utility model embodiment also discloses a stirring device, including the aforementioned stirring paddle, vessel body 200, driving component 300, bearing seat 400, and stirring shaft 500. The driving component 300 is installed on the top of the vessel body 200, and the driving end of the driving component 300 extends into the interior of the vessel body 200. The bearing seat 400 is located at the bottom center of the vessel body 200. The stirring shaft 500 is installed on the driving end of the driving component 300. Several stirring paddles are sequentially installed on the stirring shaft 500 from top to bottom, and the tail end of the stirring shaft 500 is movably connected to the bearing seat 400.

[0052] refer to Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown in this embodiment, when the device is started, the output end of the drive unit 300 rotates clockwise to drive the two sets of stirring blades installed on the stirring shaft 500. Each set of stirring blades can drive the stirring material to rotate up and down, so that the entire stirring material rotates up and down continuously, effectively avoiding the generation of eddies that cause uneven stirring.

[0053] Understandably, each set of stirring paddles is equipped with three stirring blades 100. The three stirring blades 100 are connected in pairs through several connecting holes 1121 and are arranged in a ring on the stirring shaft 500. They can be height-positioned on the stirring shaft 500 by matching the mounting holes 1111. The connecting part 111 has an arc-shaped structure, which can better adapt to the shape of the stirring shaft 500 and enhance the stability of the connection.

[0054] In some specific embodiments of this utility model, an anchor-type stirring paddle 600 is also included. The stirring surface of the anchor-type stirring paddle 600 is set at an angle to the horizontal plane. The anchor-type stirring paddle 600 can adapt to the shape of the bearing seat 400 and the bottom of the vessel body 200.

[0055] refer to Figure 6 As shown, in this embodiment, the anchor-type stirring paddle 600 has an arc-shaped blade that is higher in the middle and lower on both sides. This design avoids collision with the bearing housing 400. The arc-shaped blade design of the anchor-type stirring paddle 600 conforms to the bottom shape of the vessel body 200, and with the angle setting, it not only works with the stirring blade 100 to provide a certain stirring effect during device operation but also prevents the stirred material from settling at the bottom of the vessel body 200. It is understood that the anchor-type stirring paddle 600 can also be equipped with reinforcing ribs to prevent deformation, and these reinforcing ribs should be located on the non-product-propelling surface of the anchor-type stirring paddle 600 to prevent the product from sticking to the anchor-type stirring paddle 600.

[0056] In some specific embodiments of this utility model, a plurality of connecting ear brackets 700 are also included, which are arranged around the outside of the vessel body 200. (See reference) Figure 5 As shown, several connecting ear brackets 700 facilitate the installation of the device. The number of connecting ear brackets 700 can be set according to the load-bearing installation requirements, and can be two, three or four.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
