Abstract
Description
Technical Field
[0001] This application relates to the field of stirring device technology, and in particular to a novel material stirring blade structure. Background Technology
[0002] Agitator blades are key components widely used in various mixing operations. Their main function is to stir, mix, and disperse materials within a container through rotation, promoting a uniform state or achieving specific process effects. The performance of the agitator blades has a significant impact on mixing efficiency, material quality, and equipment operational stability.
[0003] Traditional agitator blades are typically simple in structure, possessing only basic mixing functions, and are insufficient to meet the diverse and specialized requirements of processing novel materials. For instance, when mixing novel materials with unique physicochemical properties, the large amount of heat generated during mixing cannot be effectively dissipated by traditional blades, easily leading to localized overheating of the material, which can affect material performance or even damage the equipment. Furthermore, for materials requiring simultaneous pulverization of agglomerated powders during mixing, ordinary agitator blades lack the corresponding pulverization function, failing to achieve ideal processing results. Additionally, the blade angle of traditional agitator blades is often fixed, unable to be flexibly adjusted according to different mixing conditions and material characteristics, limiting the improvement of mixing efficiency and uniformity.
[0004] Based on the above problems, there is an urgent need in this field for a new type of stirring blade structure to meet the increasingly diverse and refined requirements of stirring and processing of new materials. Summary of the Invention
[0005] In view of this, the present application provides a novel material stirring blade structure to solve at least one problem existing in the background art, including a blade body, one end of which is connected to an angle adjustment mechanism, the angle between the plane of the blade body and the horizontal plane is changed by the angle adjustment mechanism, and the angle adjustment mechanism is fixedly installed on the stirring shaft;
[0006] The blade body has an internal cavity, and a cooling mechanism is installed inside the cavity. The cooling mechanism includes a cooling pipe, the inlet and outlet of which are respectively located on both sides of the connection between the blade body and the angle adjustment mechanism, and are connected to the cooling assembly. The cooling assembly includes a cooling water tank and a water pump. The cooling pipe is filled with a cooling medium, and heat-conducting particles are filled between the cooling pipe and the inner wall of the cavity. Several heat exchange sections are fixedly installed on the inner wall of the cooling pipe, and the ends of the heat exchange sections are branched.
[0007] The surface of the blade body is provided with a crushing mechanism.
[0008] Optionally, the crushing mechanism includes a vibrating plate and a drive assembly, wherein the vibrating plate is connected to the blade body via the drive assembly.
[0009] Optionally, the driving component is a piezoelectric ceramic sheet, which is electrically connected to a controller, and the controller controls the magnitude and frequency of the voltage applied to the piezoelectric ceramic sheet.
[0010] Optionally, the thickness of the vibrating plate is between 0.5-3mm, the vibrating plate is elliptical, and a crushing part is fixedly installed on the surface of the vibrating plate.
[0011] Optionally, the crushing part is in the shape of a triangular pyramid or a quadrangular pyramid, and the side edges of the crushing part are provided with cutting blades.
[0012] Optionally, the angle adjustment mechanism includes an adjustment motor and a reducer, wherein the adjustment motor drives the blade body to rotate through the reducer.
[0013] Optionally, the angle adjustment mechanism is fitted with a bellows cover, the two ends of which are connected to the blade body and the stirring shaft, respectively.
[0014] Optionally, the adjustment angle of the angle adjustment mechanism is between 0 and 30 degrees.
[0015] Optionally, the ratio of the width of the blade body at the end away from the stirring shaft to the width of the blade body at the end closer to the stirring shaft is between 1 / 3 and 1 / 2.
[0016] Optionally, a temperature sensor may also be fixedly mounted on the surface of the blade body.
[0017] The beneficial effects of this application are as follows:
[0018] The blade body of this application incorporates a cooling mechanism, including a spiral-shaped circulating cooling pipe. Through a cooling water tank, a water pump, and a cooling medium filled within the cooling pipe, effective cooling of the blade is achieved. When the powder material generates heat during stirring, the cooling medium carries away the heat, preventing the stirred powder particles from disintegrating, thus ensuring the stability of the stirring process and avoiding the problem of material properties being affected by blade overheating. The heat-conducting particles filling the space between the cooling pipe and the inner wall of the cavity further enhance heat transfer efficiency, allowing heat to be transferred more quickly from the blade body to the cooling medium within the cooling pipe. Simultaneously, several heat exchange sections are fixedly installed on the inner wall of the cooling pipe, with branched ends, increasing the heat exchange area and improving the cooling effect.
[0019] The pulverizing mechanism provided on the surface of the impeller body in this application can pulverize and refine materials during the mixing process. The vibrating plate in the pulverizing mechanism is driven to vibrate by a drive component (such as a piezoelectric ceramic plate). When the vibrating plate vibrates, the pulverizing part, which is fixedly installed on its surface in the shape of a triangular or quadrangular pyramid with cutting edges on the side, can break up the powder material that clumps together during the mixing process, thereby improving the mixing efficiency.

[0035] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.
[0036] This invention relates to a novel material stirring blade structure, and its specific embodiments will be described in detail below so that those skilled in the art can clearly understand and implement the invention.
[0037] like Figures 1 to 4 As shown, the new material stirring blade structure mainly includes a blade body 1, an angle adjustment mechanism 2, a cooling mechanism 3, and a crushing mechanism 4. Each part works together to achieve specific stirring, cooling, and crushing functions.
[0038] Includes a blade body, one end of which is connected to an angle adjustment mechanism. The angle between the plane of the blade body and the horizontal plane is changed by the angle adjustment mechanism. The angle adjustment mechanism is fixedly installed on the stirring shaft 7.
[0039] The blade body has a cavity 11 inside, and a cooling mechanism is installed inside the cavity to effectively cool the heat generated by the blade body during the stirring process.
[0040] The cooling mechanism includes a cooling pipe 31, which improves cooling efficiency by increasing the contact area between the cooling pipe and the cooling medium. The inlet 311 and outlet 312 of the cooling pipe are respectively located on both sides of the connection between the blade body and the angle adjustment mechanism, and are connected to the cooling assembly. The cooling assembly includes a cooling water tank 32 and a water pump 33. The water pump is responsible for transporting the cooling medium (such as water) from the cooling water tank to the cooling pipe through the pipe, forming a circulating cooling system.
[0041] Cooling medium is filled inside the cooling pipe to facilitate heat transfer and removal. Simultaneously, thermally conductive particles 34 are filled between the cooling pipe and the inner wall of the cavity, further enhancing the efficiency of heat transfer from the blade body to the cooling pipe. Furthermore, several heat exchange sections 35 are fixedly installed on the inner wall of the cooling pipe, with bifurcated ends. This design increases the heat exchange area, allowing the cooling medium to more fully exchange heat with the inner wall of the cooling pipe as it flows through, thus achieving a better cooling effect on the blade body.
[0042] It is understandable that during the mixing of powder particles, the powder may release heat due to chemical reactions. If a large amount of heat accumulates in the powder particles during mixing, there may be installation hazards. Therefore, a cooling mechanism is installed in the blade body to remove the heat from the powder particles through a cooling medium during the mixing process.
[0043] The surface of the blade body is provided with a crushing mechanism. The crushing structure is used to break up the powder material that has agglomerated during the mixing process of the blade body, thereby improving the mixing efficiency.
[0044] Furthermore, the crushing mechanism includes a vibrating plate 41 and a drive assembly 42, and the vibrating plate is connected to the blade body through the drive assembly.
[0045] To elaborate further, the piezoelectric ceramic plate is electrically connected to the controller. During actual operation, the controller adjusts the voltage and frequency applied to the piezoelectric ceramic plate according to the actual needs of the stirring process. When the piezoelectric ceramic plate receives a suitable voltage signal, it vibrates, which in turn drives the vibrating plate to vibrate.
[0046] Furthermore, the thickness of the vibrating plate is between 0.5-3mm, the vibrating plate is elliptical, and a crushing part 43 is fixedly installed on the surface of the vibrating plate.
[0047] Furthermore, the crushing section is shaped like a triangular or quadrangular pyramid, with a crushing convex height between 2-5 mm and a bottom side length between 1-3 mm. The side edges of the crushing section are provided with cutting blades. The cutting blades can cut and segment the agglomerated particles under the vibration of the vibrating plate, further assisting in the crushing process of agglomerated particles.
[0048] Furthermore, the angle adjustment mechanism includes an adjustment motor 21 and a reducer 22, wherein the adjustment motor drives the blade body to rotate through the reducer.
[0049] Furthermore, the angle adjustment mechanism is fitted with a bellows cover 5, with its two ends connected to the blade body and the stirring shaft, respectively. The bellows cover isolates the angle adjustment mechanism from external powder particles, preventing powder particles from entering the angle adjustment mechanism.
[0050] Furthermore, the adjustment angle of the angle adjustment mechanism is between 0 and 30 degrees.
[0051] Furthermore, the ratio of the width of the blade body at the end furthest from the stirring shaft to the width of the blade body at the end closest to the stirring shaft is between 1 / 3 and 1 / 2.
[0052] Each blade body is approximately a twisted trapezoid, gradually narrowing from the root to the tip. The root of the blade body is connected to the stirring shaft and has a relatively large width, gradually decreasing in width towards the tip, which is approximately one-third to one-half the width of the root. This gradual width design allows the stirred powder particles to form a more reasonable flow field as they flow through the blades, avoiding localized excessively fast or slow flow velocities, thereby improving the uniformity of stirring.
[0053] Furthermore, a temperature sensor 6 is also fixedly installed on the surface of the blade body. This temperature sensor can monitor the temperature change of the blade body in real time during the stirring process, so as to understand the heat distribution and other information during the stirring process and provide data support for subsequent operation control.
[0054] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
