Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of material mixing and stirring, specifically to a stirring blade and a stirring device. Background Technology
[0002] Syrup is a viscous solution containing a high concentration of sugar, produced through boiling or other techniques. The syrup production process requires stirring to achieve the desired concentration. Generally, sugar granules are mixed and stirred with the solution. Due to gravity, the sucrose granules sink to the bottom of the mixing tank. However, current syrup mixers can only stir the solution; some of the sunken sugar granules cannot rotate due to their own gravity. This results in uneven mixing of the granules, and in severe cases, the material at the bottom of the container may burn, significantly impacting syrup quality and production efficiency.
[0003] In summary, existing mixing devices suffer from uneven mixing during syrup production. Utility Model Content

[0037] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0038] See the structural schematic diagram of the stirring device of this utility model. Figure 1 The stirring device includes a transmission mechanism and stirring blades. The transmission mechanism includes a transmission sprocket 5. The rotating shaft 2 passes through the structural fixing block 4 and is fixedly connected to the transmission sprocket 5. The rotating shaft 2 is rotatably connected to the structural fixing block 4. The structural fixing block 4 is fixedly mounted on the mounting plate 6. The rotating shaft 2 can slide vertically on the structural fixing block 4. An elastic component 3 that drives the rotating shaft 2 to move downward is sleeved below the structural fixing block 4. Specifically, the structural fixing block 4 is configured with a through hole structure in the vertical direction, and the rotating shaft 2 can freely rotate and slide up and down in the through hole structure. In this embodiment, the elastic component 3 is a spring. The spring is set at the lower part of the rotating shaft 2. One stop block abuts against the structural fixing block 4, and another stop block is sleeved at the lower part of the rotating shaft 2. The two ends of the spring abut against the two stop blocks respectively.
[0039] The stirring blade includes a rotating shaft 2 and blades. The blades have a rotating shaft connection end 11 and a stirring end. The stirring end is provided with stirring teeth 12 and contacts the bottom of the container. The gap between adjacent stirring teeth 12 is a tooth gap 13. The width of the stirring teeth 12 is greater than the width of the tooth gap 13. The rotating shaft 2 is fixedly connected to the rotating shaft connection end 11. The axis of the rotating shaft 2 is located on the stirring teeth 12 and close to the tooth gap 13. When the blade rotates around the axis, the stirring teeth 12 on one side of the axis cover the tooth gap 13 on the other side. In this embodiment, there are 5 stirring teeth 12 and 4 tooth gaps 13. The stirring teeth 12, counted from right to left, are the first stirring tooth 12, the second stirring tooth 12, the third stirring tooth 12, and so on. The tooth gaps 13, counted from right to left, are the first tooth gap 13, the second tooth gap 13, the third tooth gap 13, and the fourth tooth gap 13. The axis of the rotating shaft 2 is located on the third stirring tooth 12 and close to the left edge of the third stirring tooth 12. When the blade rotates around the rotating shaft 2, the first stirring tooth 12 covers the area outside the fifth stirring tooth 12, the second stirring tooth 12 covers the area of the fourth tooth cavity 13, the third stirring tooth 12 covers the area of the third tooth cavity 13, the fourth stirring tooth 12 covers the area of the second tooth cavity 13, and the fifth stirring tooth 12 covers the area of the first tooth cavity 13.
[0040] The working process of the stirring device in this embodiment is as follows: the power drives the sprocket 5 to rotate, the sprocket 5 drives the rotating shaft 2 to rotate and drives the blades to rotate. During the rotation, when the blades rotate around the axis of the rotating shaft 2, the stirring teeth 12 on one side of the axis cover the tooth gaps 13 on the other side. That is, during stirring, the tooth gaps 13 between two adjacent stirring teeth 12 are used for mixing the syrup, ensuring that the sugar particles and the solution are fully mixed and dissolved, thus improving the uniformity of the syrup mixture. At the same time, the spring generates a downward thrust on the rotating shaft 2, ensuring that the stirring teeth 12 are in full contact with the bottom of the container. In this way, the stirring teeth 12 can stir the sugar particles at the bottom of the container, and there will be no sugar particles remaining at the bottom of the container, ensuring that no material sticks to the bottom, and further preventing the bottom material from burning when there is a heating system.
[0041] See the structural diagram of the blade in Example 1. Figure 2 and Figure 3 That is, there are 5 stirring teeth 12 and 4 toothed openings 13, and the stirring teeth 12 are rectangular.
[0042] In a specific embodiment, the side of the stirring tooth 12 is provided with a flow guiding structure 14, which can further avoid local deposition and make the temperature of the syrup in the container more uniform.
[0043] Figure 4 This is a schematic diagram of a flow guiding structure 14 on the side of the stirring tooth 12. That is, from the top view, the stirring tooth 12 is provided with an arc-shaped boss structure on both sides.
[0044] Figure 5 This is a schematic diagram of a flow guiding structure 14 on the side of the stirring tooth 12. That is, from the top view, isosceles triangular boss structures are set on both sides of the stirring tooth 12.
[0045] Figure 6 This is a schematic diagram showing that the stirring tooth 12 has a flow guiding structure 14 on its side. That is, from the top view, the stirring tooth 12 has two concave arc-shaped protrusions on both sides.
[0046] Figure 7 This is a schematic diagram of a flow guiding structure 14 on the side of the stirring tooth 12. That is, from the top view, right-angled triangular boss structures are set on both sides of the stirring tooth 12.
[0047] In a specific embodiment, the bottom of the stirring teeth 12 is provided with an anti-crystallization structure to prevent syrup from depositing and burning at the bottom of the container. The anti-crystallization structure is a microgroove array, such as... Figure 8The anti-crystallization structure shown features microgrooves spirally distributed radially along the blade; the microgrooves are 0.5-1 mm deep, 0.1-0.3 mm wide, and spaced 1.5-2.5 mm apart. This spiral distribution of microgrooves induces secondary eddies, breaking the laminar boundary layer of the syrup, enhancing micro-shear, and forcibly dispersing and shearing unmelted sugar particles, thus preventing scorching at the bottom of the container. Furthermore, it improves the effective diffusion coefficient of the syrup, ensuring uniform mixing and reducing the deposition rate of coking deposits.
[0048] In a specific embodiment, the height of the toothed cavity 13 can be greater than the surface height of the liquid being stirred to ensure uniform stirring. Alternatively, depending on actual needs, the height of the toothed cavity 13 can be less than the surface height of the liquid being stirred, allowing for the stirring of more syrup and improving production efficiency.
[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
