[0025] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0026] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.
[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0028] One of the preferred embodiments of the present application is as follows: Figures 1 to 7 As shown, a stirring structure includes a rotating shaft 1, a first stirring component 2 and a second stirring component 3, wherein the first stirring component 2 and the second stirring component 3 are both mounted on the rotating shaft 1. It can be understood that when stirring, the rotating shaft 1 will rotate under the action of an external driving device (such as a motor), so the stirring components (i.e., the first stirring component 2 and the second stirring component 3) will rotate in a circle to stir and mix the materials, and at the same time, the first stirring component 2 can transport the materials in a first direction, and the second stirring component 3 can transport the materials in a second direction, so that the materials can be fully mixed and stirred, and the stirring effect is greatly improved.
[0029] For example, Figure 7As shown, at this time, the first stirring component 2 is set to make the material conveying direction f (to the left), and the second stirring component 3 is set to make the material conveying direction e (to the right), so that the material can circulate during the stirring process and maintain a dynamic balance in the drying kettle 6, thereby effectively avoiding the stratification of the material in the drying kettle 6. In addition, the conveying directions of the first stirring component 2 and the second stirring component 3 are opposite, which can further improve the stirring efficiency and ensure the uniform mixing of the material in the drying kettle 6. In practical applications, this stirring structure is particularly suitable for materials with poor fluidity, such as high-viscosity liquids, mixtures containing solid particles, powders, etc. Of course, as Figure 1 As shown, it is assumed that the material can be transported up and down under the action of the stirring structure, so that the materials between multiple intervals B can be fully mixed, greatly improving the mixing effect.
[0030] Of course, there are many structural forms of the first stirring component 2 and the second stirring component 3. A specific embodiment is provided below for illustration:
[0031] like Figure 3 and Figure 4 As shown, a stirring rod 4 is installed on the outside of the rotating shaft 1 and is perpendicular to it. The first stirring component 2 includes a first stirring blade 201, and the second stirring component 3 includes a second stirring blade 301. The first stirring blade 201 and the second stirring blade 301 are both installed on the outside of the stirring rod 4 and are arranged at intervals. The first stirring blade 201 and the second stirring blade 301 are both inclined relative to the axis of the rotating shaft 1 and the inclination directions of the two are opposite.
[0032] It should be known that, since the first stirring blade 201 and the second stirring blade 301 are both inclined, the two stirring blades will also generate a thrust along the axial direction of the rotating shaft 1 on the material when they rotate in a circle, and the two stirring blades have different inclination directions, for example, one is inclined to the left and the other is inclined to the right, so that the following can be generated: Figure 7 The material shown is transported in two directions.
[0033] Furthermore, in order to improve the conveying effect, Figure 3 As shown, the above-mentioned inclined stirring blades can adopt a spiral structure to form a spiral ribbon, so that the material can move along the spiral path during the stirring process, thereby improving the conveying effect and improving the mixing uniformity. In addition, the stirring blades (i.e., spiral ribbons) with a spiral structure can also reduce the shear force of the material during the stirring process, which is particularly important for protecting the physical properties of the material, especially when handling sensitive or fragile materials. In practical applications, the design of this spiral stirring blade can effectively improve the stirring efficiency, reduce energy consumption, and can adapt to materials of different types and viscosities. By adjusting the pitch and inclination angle of the stirring blade (i.e., spiral ribbon) spiral, the stirring effect can be further optimized to meet specific process requirements.
[0034] Based on the above embodiments, in this embodiment, if Figure 4 As shown, the first stirring blade 201 and the second stirring blade 301 are both inclined at an angle α relative to the axis of the rotating shaft 1 (ie, the two are symmetrically inclined), wherein 10°≤α≤30°.
[0035] It is understandable that if the inclination angle of the stirring blade is too small (for example, less than 10°), the stirring blade will have a poor effect on pushing the material, thereby causing poor material conveying effects along the first direction and the second direction. If the inclination angle of the stirring blade is too large (for example, greater than 30°), although it can have a good material conveying effect, Figure 5 As shown, the greater the inclination angle of the stirring blade, the shorter its projection on the axis of the rotating shaft 1 will be, which will reduce the stirring range of the stirring blade and the material, that is, the stirring effect will be greatly reduced; of course, more stirring blades can be provided, but this will make the structure more complicated and increase the cost. Therefore, the inclination angle α is preferably set between 10° and 30°, for example, it is preferably set to be inclined at 15°.
[0036] Furthermore, in order to improve the mixing and conveying effect of materials, Figure 2 As shown, the stirring rods 4 are provided in multiple groups and are arranged at equal intervals, and adjacent stirring rods 4 are perpendicular to each other, so that the projections of adjacent first stirring components 2 and second stirring components 3 along the axis of the rotating shaft 1 at least partially overlap.
[0037] Specifically, Figure 5 As shown, we assume that there are four groups of stirring rods 4, the rightmost (fourth) stirring rod 4 is vertically arranged, and the third stirring rod 4 is horizontally arranged, and so on, the second stirring rod 4 is vertically arranged, and the first stirring rod 4 is horizontally arranged; that is, the installation positions of two adjacent stirring rods 4 are staggered, and the two stirring blades on the same stirring rod 4 have the same projection length toward the axis of the rotating shaft 1.
[0038] For example, Figure 5 As shown, we take the first and second stirring rods 4 on the left side as examples for explanation. The two ends of the stirring blade on the first stirring rod 4 are projected toward the axial direction of the rotating shaft 1 at points a and c, and the projection length is ac. The stirring blade on the second stirring rod 4 is projected toward the axial direction of the rotating shaft 1 at points b and d, and the projection length is bd. And ac and bd have an overlapping part, namely bc. It can be understood that, that is to say, the mutual cooperation of the multiple stirring blades makes the projection in the axial direction of the rotating shaft 1 continuous, and the rotating shaft 1 coincides with the center line of the drying kettle 6. Therefore, the stirring range of the multiple stirring blades in the axial direction of the drying kettle 6 is continuous, so that the material in the drying kettle 6 can be fully stirred and the stirring effect can be improved.
[0039] Furthermore, Figure 2 As shown, the stirring rods 4 are symmetrically arranged and distributed with respect to the axis of the rotating shaft 1; for example, the stirring rods 4 are arranged in four groups, and in this case, the stirring rods 4 are arranged in eight groups. This symmetrically distributed design of the stirring rods 4 not only ensures the uniformity of stirring, but also helps to achieve uniform mixing of the materials in the drying kettle 6. In actual production, this design can effectively avoid the generation of stirring dead angles and ensure the stability and reliability of the stirring effect.
[0040] Based on the above embodiments, in this embodiment, if Figure 2 As shown, the first stirring blade 201 and the second stirring blade 301 are both installed on the first orientation side of the stirring rod 4. It can be understood that when rotating, assuming that the rotating shaft 1 rotates in the first orientation (i.e., rotates counterclockwise), the stirring rod 4 can support the two stirring blades. Specifically, the first orientation side can be understood as the installation position where the stirring rod 4 can support the stirring blades when rotating. For example, when stirring, the stirring blades will have a thrust effect on the material, and the material has a reaction force on the stirring blades. At this time, the stirring rod 4 can support the force it receives, thereby making the installation of the stirring blades more stable.
[0041] In one of the embodiments of the present application, Figure 6 As shown, since the material will adhere to the inner wall of the drying kettle 6 during stirring, thereby reducing the flow effect of the material, a scraper 5 can be installed on the outside of the stirring component. Of course, the scraper 5 can be installed on the outside of both stirring components, or a scraper 5 can be installed on one of the stirring components; the specific installation position can be set by technicians in this field according to actual conditions.
[0042] For example, Figure 7 As shown, the drying kettle 6 is a horizontal structure, so the materials are easily accumulated at the two ends and the bottom of the drying kettle 6, and we can install the first stirring blade 201 close to the bottom or top of the drying kettle 6, so that the first stirring blade 201 can play the role of scraping materials. Therefore, we can install the scraper 5 on the two first stirring blades 201 at both ends of the rotating shaft 1, and after installation, the scraper 5 is close to or against the two ends of the drying kettle 6, and then during stirring, the materials adhered to the inner wall of the drying kettle 6 can be scraped off well to prevent the accumulation of materials.
[0043] In this embodiment, Figure 2As shown, the two ends of the rotating shaft 1 are matched with the two ends of the drying kettle 6 in actual use, so not all parts of the rotating shaft 1 are equipped with the stirring rod 4, that is, the stirring rod 4 is mainly installed in the middle of the rotating shaft 1, so the middle of the rotating shaft 1 is more easily damaged by the force, and if the entire rotating shaft 1 is replaced when a failure occurs, the cost will be greatly increased. Therefore, the rotating shaft 1 includes a central shaft 101 and a pair of mounting shafts 102, and the two ends of the central shaft 101 are detachable and matched with the corresponding mounting shafts 102, and the first stirring assembly 2 and the second stirring assembly 3 are both installed on the central shaft 101.
[0044] For example, flanges may be provided at both ends of the central shaft 101, and flanges may also be provided at the corresponding mounting ends of the mounting shaft 102 and the central shaft 101, and the two mounting ends may be detachably mounted by the cooperation of the flanges and bolts. Therefore, when any of the central shaft 101 and the two mounting shafts 102 is damaged, they can be disassembled and replaced accordingly without replacing the entire rotating shaft 1, which greatly saves costs.
[0045] Another aspect of the present application provides a drying device, comprising the above-mentioned stirring structure.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
