Description

Technical Field

[0001] This utility model relates to the field of agitator technology, and in particular to a high-viscosity agitator. Background Technology

[0002] In industrial production, the mixing of high-viscosity materials (such as resins, adhesives, and paste-like foods) is a key process. Due to their unique rheological properties, such as high cohesion and large viscous resistance, high-viscosity materials pose many challenges to traditional mixing processes.

[0003] In existing technologies, a single-blade structure is usually used. The simple rotation of the blades makes it difficult for the material to form an effective flow circulation, especially in the area near the container wall and bottom, where it is easy to form an angle, causing the material to not participate in the stirring process evenly, resulting in uneven mixing. In the process of stirring high-viscosity materials, a large number of bubbles will also be generated. If these bubbles are not discharged in time and effectively, they will be mixed into the final product, affecting the product's appearance, density and performance indicators. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that typically employ a single-blade structure. The simple rotation of the blades makes it difficult for materials to form an effective flow circulation, especially in areas near the container wall and bottom, where angles are easily formed, causing the materials to not participate evenly in the stirring process, resulting in uneven mixing. In the process of stirring high-viscosity materials, a large number of bubbles are also generated. If these bubbles are not discharged in a timely and effective manner, they will mix into the final product, affecting the product's appearance, density, and performance indicators. Therefore, this invention proposes a high-viscosity stirrer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-viscosity stirrer includes a mounting frame and a motor fixed on the mounting frame. A stirring shaft connected to the motor is rotatably mounted on the mounting frame, and stirring blades are fixed on the stirring shaft. The high-viscosity stirrer further includes:

[0007] The defoaming mechanism includes a defoaming plate that can be lifted and lowered at the bottom of the mounting frame. The defoaming plate has a circular hole at the coaxial position with the stirring shaft for the stirring shaft to pass through. The stirring shaft is fixed between the mounting frame and the defoaming plate to drive the defoaming plate to move downward to defoam. An auxiliary component is provided between the defoaming plate and the mounting frame to reset the defoaming plate upward.

[0008] The frame blade is fixed to the bottom end of the stirring shaft.

[0009] Furthermore, the extrusion assembly includes a turntable fixed between the defoaming plate and the mounting frame along the length of the stirring shaft, and a plurality of cylinders arranged in a ring array at the bottom of the turntable and corresponding to the top of the defoaming plate. The bottom end of each cylinder accommodates a ball bearing through a rolling groove. The defoaming plate is provided with inclined blocks corresponding to the plurality of balls, allowing the balls to roll and extrude upwards.

[0010] Furthermore, the inclined block is provided with an inclined surface for the ball to roll, and the angle of the inclined surface is 35°~65°.

[0011] Furthermore, the auxiliary component includes a plurality of auxiliary rods symmetrically fixed to the top of the bubble removal plate, and one end of the auxiliary rod extends through the top of the mounting frame. The auxiliary rod is fixedly fitted with a return spring connected to the mounting frame and a limiting plate fixed to the top surface of the auxiliary rod to limit the return spring.

[0012] Furthermore, the frame leaf is formed by two symmetrical support rods and two trapezoids, and the trapezoids are formed by a vertical line extending to a sharp corner and gradually decreasing in size to a horizontal line.

[0013] Furthermore, the mounting bracket has several mounting plates protruding from both ends along its length, and each mounting plate has bolt holes for fixing the mounting bracket.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] 1. In this solution, the motor drives the stirring shaft to rotate, which in turn causes the stirring blades and frame blades to rotate simultaneously, enabling uniform stirring of the material. The two work together to form a composite flow field with bidirectional interaction between the center and the edge, ensuring that there are no stagnant areas inside the container.

[0016] 2. When bubbles are generated during the mixing process in this solution, the mixing shaft drives the turntable to rotate, and multiple cylinders make circular motion with the help of the turntable. The ball bearings at the bottom of the cylinders are squeezed by the inclined block, which pushes the inclined block to move the bubble removal plate downward, thereby treating the bubbles.

[0017] 3. In this solution, when the auxiliary rod moves downward, it drives the limiting plate downward and compresses the return spring. When the ball does not contact the inclined block, the return spring releases its elastic force, driving the limiting plate to move upward and reset. Then, the auxiliary rod drives the bubble removal plate to move upward and reset, thereby realizing the reciprocating lifting and lowering of the bubble removal plate to perform bubble removal work. This can continuously remove newly generated bubbles and ensure the stability and continuity of the bubble removal effect. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 A high-viscosity stirrer includes a mounting frame 1 and a motor 5 fixed on the mounting frame 1. A stirring shaft 501 connected to the motor 5 is rotatably mounted on the mounting frame 1, and stirring blades 2 for stirring are fixed on the stirring shaft 501. The high-viscosity stirrer also includes:

[0026] The degassing mechanism includes a degassing plate 403 that can be lifted and lowered at the bottom of the mounting frame 1. The degassing plate 403 and the stirring shaft 501 are coaxially positioned with a circular hole through which the stirring shaft 501 passes. The stirring shaft 501 is fixed between the mounting frame 1 and the degassing plate 403 with a pressing component that drives the degassing plate 403 to move downward to degas. An auxiliary component for resetting the degassing plate 403 upward is provided between the degassing plate 403 and the mounting frame 1. The pressing component includes a turntable 4 fixed along the length of the stirring shaft 501 between the degassing plate 403 and the mounting frame 1, and a plurality of cylinders 401 arranged in a ring array at the bottom of the turntable 4 and corresponding to the top of the degassing plate 403. The bottom end of the cylinders 401 is accommodated with a ball 402 through a rolling groove. The degassing plate 403 is provided with inclined blocks 404 corresponding to the plurality of balls 402 for the balls 402 to roll and press upward.

[0027] In this embodiment, when the stirring shaft 501 rotates continuously, the turntable 4 also rotates together. Under the power transmitted by the turntable 4, multiple cylinders 401 move in a circular motion along a specific trajectory. During this dynamic process, the ball bearings 402 located at the bottom of the cylinders 401 will exert a squeezing effect on the inclined block 404. This squeezing force will push the inclined block 404 to further drive the degassing plate 403 to move downward to perform degassing work, thereby effectively treating the generated bubbles and achieving a good effect of bubble removal.

[0028] Reference Figure 1 and Figure 2 The auxiliary components include a plurality of auxiliary rods 405 symmetrically fixed on the top of the bubble removal plate 403, and one end of the auxiliary rod 405 extends through the top of the mounting frame 1. The auxiliary rod 405 is fixedly sleeved with a reset spring 406 connected to the mounting frame 1 and a limiting plate 407 fixed on the top surface of the auxiliary rod 405 to limit the reset spring 406.

[0029] In this embodiment, the auxiliary rod 405 can achieve a limiting effect when the bubble removal plate 403 is raised or lowered. When the auxiliary rod 405 moves downward, it drives the limiting plate 407 to move downward and compresses the reset spring 406. When the reset spring 406 releases its elastic force, it can drive the auxiliary rod 405 to move upward and reset through the limiting plate 407, and then drive the bubble removal plate 403 to reset. This cycle repeats, achieving continuous and stable bubble removal.

[0030] Reference Figure 1 The frame blade 3 is fixed at the bottom end of the stirring shaft 501. The frame blade 3 is formed by two symmetrical support rods and two trapezoids. The trapezoids are formed by a vertical line extending to a sharp corner and gradually decreasing to a horizontal line. The cooperation between the frame blade 3 and the stirring blade 2 can fully stir the high viscosity material.

[0031] In this embodiment, when the stirring shaft 501 rotates, it is responsible for the main circulation in the radial and axial directions, pushing the material to form the main vortex. When the frame blade 3 rotates, it forces the near-wall material to flow towards the center through the edge effect, breaking the laminar boundary layer. The two work together to form a composite flow field with bidirectional interaction between the center and the edge, ensuring that there is no stagnant area in the container and achieving the effect of fully stirring the material.

[0032] Reference Figure 2 and Figure 3 The inclined block 404 is provided with an inclined surface for the ball 402 to roll. The angle of the inclined surface is 35°~65°. The mounting bracket 1 has several mounting plates protruding from both ends along the length direction, and each mounting plate has bolt holes for fixing the mounting bracket 1.

[0033] In this embodiment, when the inclined surface on the inclined block 404 comes into contact with the ball 402, it can smoothly complete the extrusion work, avoiding jamming and increasing resistance to the motor 5. The bolt holes on the mounting plate make it easy to install the device on the container to be stirred.

[0034] The implementation principle of a high-viscosity stirrer in this application embodiment is as follows: First, the mounting frame 1 needs to be accurately placed above the container holding the material to be processed. Then, the motor 5 is started. After the motor 5 starts running, it will drive the stirring shaft 501 to start rotating and be responsible for the main circulation in the radial and axial directions, pushing the material to form the main vortex. Along with the rotation of the stirring shaft 501, the stirring blade 2 and the frame blade 3 connected to it will rotate synchronously. Through the edge effect, the near-wall material is forced to flow towards the center, breaking the laminar boundary layer. The two work together to form a "center-edge" bidirectional interactive composite flow field, ensuring that there is no stagnant area in the container.

[0035] During the mixing process, some bubbles are inevitably generated. As the mixing shaft 501 continues to rotate, the associated turntable 4 also rotates. Multiple cylinders 401 move in a circular motion along a specific trajectory under the power transmitted by the turntable 4. During this dynamic process, the ball bearings 402 at the bottom of the cylinders 401 will squeeze against the inclined block 404. This squeezing force will push the inclined block 404 to further drive the degassing plate 403 to move downward. At the same time, the auxiliary rod 405 plays an important limiting function, which can ensure that the degassing plate 403 always moves vertically downward, thereby effectively treating the generated bubbles and achieving a good effect of bubble removal.

[0036] When the auxiliary rod 405 moves downward along with the bubble removal plate 403, the limiting plate 407 will also move downward, and the return spring 406 will be compressed. Once the ball 402 disengages from the inclined block 404, the elastic force stored in the return spring 406 will be released instantly, pushing the limiting plate 407 to move upward back to the initial position. Then, through the action of the auxiliary rod 405, the bubble removal plate 403 will also move upward and reset. This cycle repeats, thus realizing the lifting and lowering action of the bubble removal plate 403, enabling it to continuously and stably perform bubble removal work.

[0037] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.

[0038] The above description is only a preferred embodiment of this practice, but the scope of protection of this embodiment is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in this embodiment, based on the technical solution and the inventive concept of this embodiment, should be covered within the scope of protection of this embodiment.
