Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to an anti-tangling mixing blade assembly. Background Technology

[0002] Agitator blades are key components used to stir, mix, or homogenize liquids or suspensions. They are typically mounted on the shaft of an agitator and apply shear and hydrodynamic forces through rotation, thereby ensuring thorough mixing of substances within the container. Proper blade design can improve stirring efficiency, reduce energy consumption, and minimize material entanglement. For liquids requiring high viscosity or containing solid particles, specially designed agitator blades are even more crucial to ensure effective resistance and maintain optimal stirring performance during operation.

[0003] Patent CN221868034U discloses an anti-winding impeller agitator, including a rotating rod with an anti-winding structure on its outer surface. One end of the rotating rod has a connecting structure, and the outer surface of the connecting structure houses the impeller agitator. The rotating rod and the impeller agitator are connected via the connecting structure. One end of the rotating rod has an internal threaded groove, the inner cavity of which is movably connected to the connecting structure. The connecting structure includes a snap-fit ​​seat, the outer surface of which is fixedly fitted with an arc-shaped protrusion. The outer surfaces of the snap-fit ​​seat and the arc-shaped protrusion are movably connected to the interior of the impeller agitator. One end of the snap-fit ​​seat is fixedly fitted with a threaded short shaft, and the outer surface of the threaded short shaft is threadedly connected with a fixing cap. This invention not only prevents debris from winding around the impeller blades but also facilitates the disassembly and assembly of the impeller agitator, and its operation is simple and quick.

[0004] In existing technologies, while circularly arranged baffles can effectively prevent debris from entangled on the impeller blades, gaps between adjacent baffles and the angle between them and the fixing ring allow debris to easily accumulate and become entangled, leading to entanglement on the protective cover and affecting the normal rotation of the impeller blades. The drawback of this design is that although it theoretically reduces debris entanglement, it still has shortcomings in practical applications. Therefore, we propose an anti-entanglement stirring blade assembly. By improving the design of the protective structure, it effectively prevents debris entanglement during operation, ensuring the efficient operation and stability of the stirrer. Utility Model Content

[0005] The purpose of this invention is to provide an anti-tangling stirring blade assembly to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-tangling stirring blade assembly includes a rotating rod, combined with Figure 1 , Figure 2 and Figure 4 As shown, the bottom end of the rotating rod is detachably connected to a stirring assembly for stirring, mixing or homogenizing liquids or suspended substances. The stirring assembly includes a rotating disk, and the outer wall of the rotating disk is provided with a plurality of stirring blades arranged in a ring array.

[0008] The outer wall of the rotating rod is detachably connected to an anti-winding component, which includes a circular cover. The stirring component is located inside the circular cover to prevent the stirring component from being entangled. The outer wall of the circular cover is provided with multiple arc-shaped protective nets arranged in a ring array. The top of the circular cover is integrally formed with a conical top cover to prevent the accumulation of suspended matter. The outer wall of the conical top cover is provided with multiple fan-shaped protective nets arranged in a ring array. The arc-shaped and fan-shaped protective nets allow the solution to pass through, preventing suspended matter from entering. The bottom of the inner wall of the conical top cover is provided with a ring-shaped fixing base plate, and the bottom of the ring-shaped fixing base plate is provided with a protective net plate to prevent suspended matter from entering the conical top cover.

[0009] Preferred, combined Figure 4 and Figure 5 As shown, a rectangular connecting block is provided at the bottom of the rotating rod, and a rectangular hole a is provided on the front side of the rectangular connecting block. A strip fixing plate is connected to the rectangular hole a to fix the relative position of the rotating disk and the rotating rod.

[0010] A rectangular hole b is provided in the middle of the top of the rotating disk for the rectangular connecting block to pass through. Mounting holes c are provided at the bottom of the strip fixing plate and near the front and rear ends. A third bolt is connected to the mounting hole c. The threaded end of the third bolt is threaded to the bottom of the rotating disk, which facilitates the assembly and disassembly of the strip fixing plate and the rotating disk.

[0011] The top of the strip fixing plate is attached to the bottom of the rotating disk, and the bottom of the rotating rod is attached to the top of the rotating disk, ensuring that the positions of the rotating disk and the rotating rod are fixed.

[0012] Limiting blocks are provided on both the left and right sides of the strip fixing plate near the front end.

[0015] Preferred, such as Figure 3 As shown, the outer wall of the rotating rod is provided with a connecting plate, and the top of the connecting plate is provided with multiple mounting holes a. The mounting holes a are connected to a first bolt, and the threaded end of the first bolt is threaded to the top of the conical top cover, which facilitates the disassembly and assembly of the anti-winding component and the rotating rod. When disassembling the anti-winding component, the protective mesh plate needs to be removed first, then the strip fixing plate needs to be removed, and then the stirring component needs to be moved out of the circular cover to separate the stirring component from the rotating rod. Finally, the first bolt is removed to release the fixing of the conical top cover, and the anti-winding component can be disassembled.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This anti-entanglement stirring blade assembly, through the multi-layer protection system consisting of a circular cover, a conical top cover, and a protective mesh plate, can not only effectively block suspended substances from entering the stirring area, but also prevent debris from accumulating in structural gaps or corners. The combination design of the arc-shaped protective mesh and the fan-shaped protective mesh allows the liquid to pass through smoothly, while forming a continuous protective barrier, fundamentally reducing the risk of entanglement and ensuring the stable operation of the stirring assembly.

[0019] 2. The anti-winding stirring blade assembly has a reinforcing rod added to the outside of the stirring blade, and the top of the rotating disk is reinforced with a connecting round tube and a triangular reinforcing plate to enhance the connection strength, effectively dispersing the force on the blade, avoiding deformation or breakage caused by the impact of high viscosity materials or solid particles, and extending the service life of key components.

The anti-entanglement stirring blade assembly features a conical top cover whose conical structure guides suspended matter to slide down the slope, preventing material accumulation at the top. Combined with multiple layers of protection including an arc-shaped protective net, a fan-shaped protective net, and a protective net plate, it forms a three-dimensional protection system, further reducing the probability of entanglement and ensuring the continuity and efficiency of the stirring process.
