Description

Technical Field

[0001] This utility model belongs to the field of dispersion technology, specifically relating to a high-shear disperser for improving the dispersibility of composite stabilizers. Background Technology

[0002] In the industrial fields of plastics processing and coating production, composite stabilizers are important additives, and their dispersion effect directly affects the final performance of the product. Because composite stabilizers have high viscosity, they are prone to agglomeration during the dispersion process, making it difficult to achieve uniform dispersion, which in turn affects their stability performance.

[0003] Currently, high-shear dispersers for composite stabilizers all rely on a single rotor. With only a single rotor rotating at high speed, it is difficult to generate shear force from multiple directions for viscous composite stabilizers. Because composite stabilizers are viscous and have poor fluidity, it takes longer to disperse them, resulting in low dispersion efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, the present invention provides a high-shear disperser for improving the dispersibility of composite stabilizers, characterized in that it includes a fixed column, a top plate, and a drive assembly. The drive assembly includes a motor, a first rotating shaft, a first gear, a second gear, and a second rotating shaft. A first rotor is fixedly connected to the lower surface of the first rotating shaft, and a second rotor is fixedly connected to the lower surface of the second rotating shaft. A high-shear ribbon propeller is fixedly connected to the side surface of the first rotating shaft, and a connecting rod is fixedly connected to the side surface of the first rotating shaft. A fixing ring is fixedly connected to the end of the connecting rod away from the first rotating shaft.

[0005] Through the above technical solution, the structure adopts a multi-component collaborative drive assembly. The first rotor, the second rotor and the high-shear ribbon propeller work together. Compared with the traditional single rotor disperser, it can achieve multi-dimensional dispersion. At the same time, the design of the fixing ring and the connecting rod enhances the structural stability of the high-shear ribbon propeller.

[0006] The present invention is further configured such that the output end of the motor is fixedly connected to the first rotating shaft, the side surface of the first rotating shaft is fixedly connected to the first gear, the side surface of the first gear is meshed with the second gear, and the side surface of the second rotating shaft is fixedly connected to the second gear.

[0007] The above technical solution achieves linkage between the first and second rotating shafts through gear transmission, thereby driving the first and second rotors to rotate in different directions, generating the shear force required for dispersion. The opposite rotation of the first and second rotors forms a cross shear field, improving the dispersion efficiency of the composite stabilizer and shortening the dispersion time.

[0008] The present invention is further configured such that a protective box is fixedly connected to the lower surface of the top plate, the side surface of the first rotating shaft is rotatably connected to the protective box, a bearing is fixedly connected to the top inner wall of the protective box, the inner surface of the bearing is fixedly connected to the second rotating shaft, and the side surface of the second rotating shaft is rotatably connected to the protective box.

[0009] Through the above technical solution, the protective box protects the first and second gears inside, and the protective box and bearings support the first and second rotating shafts. The bearings ensure the stable rotation of the second rotating shaft, thereby improving the stability and reliability of the equipment during operation.

[0010] The present invention is further configured such that a support plate is fixedly connected to the upper surface of the top plate, the side surface of the support plate is fixedly connected to the motor, and the upper surface of the top plate is fixedly connected to the motor.

[0011] Through the above technical solutions, the support plate and top plate play a role in fixing the motor, ensuring that the motor is installed firmly, the power transmission is stable, and the overall operation of the disperser is stable.

[0012] The present invention is further configured such that the interior of the fixed column is provided with a groove, the bottom inner wall of the groove is fixedly connected to a multi-stage cylinder, the output end of the multi-stage cylinder is fixedly connected to a movable column, the inner surface of the groove is slidably connected to the movable column, and the upper surface of the movable column is fixedly connected to the top plate.

[0013] The above technical solution uses the extension and retraction of multi-stage cylinders to drive the moving column to slide within the groove, thereby adjusting the height of the top plate to meet the working height requirements of the disperser under different working conditions and improve the versatility and adaptability of the equipment.

[0014] The present invention is further configured such that a base plate is fixedly connected to the lower surface of the fixed column, and a support foot is fixedly connected to the lower surface of the base plate.

[0015] Through the above technical solution, the base plate provides a bottom support plane for the disperser, while the support feet enhance the stability of the equipment's contact with the ground and prevent the equipment from moving.

[0016] The present invention is further configured such that the side surface of the fixing ring is fixedly connected to the high-shear ribbon propeller.

[0017] By using the above technical solutions, the fixed connection between the fixing ring and the high-shear ribbon propeller is strengthened, the installation stability of the high-shear ribbon propeller is further clarified, and it is ensured that it will not loosen during high-speed rotation, thus guaranteeing the dispersion effect.

[0018] The beneficial effects of this utility model are as follows: By setting up components such as a drive assembly, a first rotor, a second rotor, and a high-shear ribbon propeller, a three-dimensional cross-shear field can be constructed. The shear teeth on the rotors generate shear forces in opposite directions in the intersecting areas. Simultaneously, under the action of the high-shear ribbon propeller, the viscous composite stabilizer is subjected to radial shear and axial tension, which can shorten the shear dispersion time of the material and improve the dispersion efficiency of the material. Furthermore, when the multiple sets of gears rotating in opposite directions operate, they will form complementary material circulation paths in the dispersion chamber. The centrifugal force generated by the counter-rotation of the first and second rotors causes the material to form vertical convection around the rotor, which can eliminate dead corners and improve the shear rate in the edge area.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1-4As shown, this embodiment of a high-shear disperser for improving the dispersibility of composite stabilizers includes a fixed column 1, a top plate 2, and a drive assembly. The drive assembly includes a motor 3, a first rotating shaft 4, a first gear 5, a second gear 6, and a second rotating shaft 7. The output end of the motor 3 is fixedly connected to the first rotating shaft 4. The side surface of the first rotating shaft 4 is fixedly connected to the first gear 5, and the side surface of the first gear 5 meshes with the second gear 6. The side surface of the second rotating shaft 7 is fixedly connected to the second gear 6. A first rotor 8 is fixedly connected to the lower surface of the first rotating shaft 4, and a second rotor 9 is fixedly connected to the lower surface of the second rotating shaft 7. A high-shear ribbon paddle 10 is fixedly connected to the side surface of the first rotating shaft 4. When the motor 3 is started, the output end of the motor 3 drives the first rotating shaft 4, the first gear 5, the first rotor 8, the fixed ring 18, the connecting rod 20, and the high-shear ribbon paddle 10 to rotate and shear and disperse the material. A connecting rod 20 is fixedly connected to the side surface of the first rotating shaft 4, and a fixed ring 18 is fixedly connected to the end of the connecting rod 20 away from the first rotating shaft 4. The side surface of the fixed ring 18 meshes with the high-shear ribbon paddle 9. The fixed connection of the paddle 10, the fixed ring 18, and the connecting rod 20 increases the stability of the structural connection, ensuring that it will not loosen during high-speed rotation and guaranteeing the dispersion effect. The rotation of the first gear 5 simultaneously drives multiple sets of second gears 6, second rotating shafts 7, and second rotors 9 to rotate in opposite directions. This generates multi-directional shearing force to quickly shear and disperse the material in the dispersion cylinder. There are three sets of second gears 6, second rotating shafts 7, and second rotors 9. The three sets of second rotors 9 rotating in opposite directions form a multi-angle, multi-layered shearing zone with the first rotor 8, so that the material is subjected to radial, axial, and circumferential shearing forces in the dispersion chamber at the same time, which can accelerate the shearing and dispersion efficiency. Moreover, the second rotors 9 and the first rotor 8 have different heights. When the three sets of second rotors 9 rotating in opposite directions to the first rotor 8 are running, they will form a complementary material circulation path in the dispersion chamber. The centrifugal force generated by the counter-rotation of the first rotor 8 and the second rotors 9 causes the material to form an up-and-down convection around the rotor, which can optimize the flow field, eliminate dead angles, and improve the shearing rate of the edge area.

[0023] A protective box 12 is fixedly connected to the lower surface of the top plate 2. The protective box 12 protects the first gear 5 and the second gear 6 inside. The side surface of the first rotating shaft 4 is rotatably connected to the protective box 12. A bearing 11 is fixedly connected to the inner top wall of the protective box 12. The bearing 11 makes the second rotating shaft 7 rotate more flexibly and also provides support for it. The inner surface of the bearing 11 is fixedly connected to the second rotating shaft 7. The side surface of the second rotating shaft 7 is rotatably connected to the protective box 12. A support plate 13 is fixedly connected to the upper surface of the top plate 2. The side surface of the support plate 13 is fixedly connected to the motor 3. The upper surface of the top plate 2 is fixedly connected to the motor 3. The support plate 13 and the top plate 2 fix the motor 3, ensuring that the motor 3 is stably installed, making the power transmission stable, and ensuring the overall stability of the disperser operation.

[0024] The fixed column 1 has a groove 15 inside. A multi-stage cylinder 16 is fixedly connected to the bottom inner wall of the groove 15. A movable column 17 is fixedly connected to the output end of the multi-stage cylinder 16. The inner surface of the groove 15 is slidably connected to the movable column 17. The upper surface of the movable column 17 is fixedly connected to the top plate 2. By starting the extension and retraction of the multi-stage cylinder 16, the movable column 17 is driven to slide in the groove 15, thereby realizing the adjustment of the height of the top plate 2, meeting the requirements of the working height of the disperser under different working conditions, and improving the versatility and adaptability of the equipment. A base plate 14 is fixedly connected to the lower surface of the fixed column 1. A support foot 19 is fixedly connected to the lower surface of the base plate 14. The base plate 14 provides a bottom support plane for the disperser, and the support foot 19 enhances the contact stability between the equipment and the ground. In this application, the motor 3 and the multi-stage cylinder 16 are both electrically connected to a controller on one side.

[0025] The working principle of this utility model is as follows: In use, the composite stabilizer to be dispersed is placed in the dispersion cylinder, and the dispersion cylinder is moved to the center position below the second rotor 9. The multi-stage cylinder 16 is started to drive the moving column 17 and the top plate 2 to move down to a suitable position for dispersion. The motor 3 is started, and the output end of the motor 3 drives the first rotating shaft 4, the first gear 5, the first rotor 8, the fixed ring 18, the connecting rod 20, and the high-shear screw propeller 10 to rotate, thereby shearing and dispersing the material. The rotation of the first gear 5 simultaneously drives multiple sets of second gears 6, the second rotating shaft 7, and the second rotor 9 to rotate in the opposite direction. Under the action of the first rotor 8, the second rotor 9, and the high-shear screw propeller 10, the material in the shearing and dispersing cylinder can form a multi-directional shearing force, which quickly shears and disperses the material in the cylinder, improving the efficiency of shearing and dispersing.
