Description

Technical Field

[0001] This utility model relates to the field of internal mixer technology, and in particular to a dual-power internal mixer. Background Technology

[0002] Most existing internal mixers use a structure of one motor and one gearbox, which distributes the motor power to drive two rotors through the gear. The speed ratio is a fixed value, which makes it difficult to meet the flexible adjustment requirements of the speed difference under different process conditions, thus limiting the further exploration and optimization of process parameters.

[0003] Furthermore, traditional internal mixers are mainly used in the rubber and plastics processing field, where the requirements for the equipment's sealing performance are not high. However, in the preparation of electrode materials, because the materials are highly sensitive to oxygen and water vapor, processing must be carried out in a vacuum or low-oxygen environment. Therefore, the internal mixer must have a reliable sealing structure to meet the requirements of the vacuum process.

[0004] Furthermore, most existing internal mixers are industrial-grade equipment, which are large in size and not suitable for space-constrained laboratory environments, thus limiting their application in experimental research. Summary of the Invention

[0005] To address this, the present invention provides a dual-power internal mixer equipped with two independent drive motors that drive two rotors respectively. The speed of each motor can be adjusted to achieve flexible control of different rotor speed ratios, thus meeting the needs of material processing parameter optimization and performance research.

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0043] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0044] Reference Figures 1 to 3 As shown, this utility model discloses a dual-power internal mixer, comprising:

[0045] Container 1, with bearing cavities 11 respectively provided at opposite ends of the container 1, and bearings provided inside the bearing cavities 11;

[0046] Two rotor assemblies 2, each rotor assembly 2 including a rotor 21 disposed inside the container 1 and a rotor shaft 22 rotatably connected to the bearing cavity 11 and connected to the rotor 21;

[0047] Two drive mechanisms 3, each drive end of which is connected to one end of a rotor shaft 22;

[0048] The pressing component 4 includes a lid 41 rotatably connected to the top of the container 1, a pressing drive device 42 disposed on the lid 41, and an upper bolt 43 driven by the pressing drive device 42.

[0049] With the above setup, the two rotors 21 are driven by independent servo motors, and the two motors can be independently speed-adjusted, thereby enabling flexible adjustment of the speed ratio of different rotors 21. This is beneficial for testing and optimizing different formulations and process parameters, and facilitates the exploration of the influence of speed ratio on material mixing behavior and final performance.

[0050] In one embodiment, refer to Figure 5 As shown, each of the drive mechanisms 3 includes a drive motor 31, a reducer 32, pulleys 33, and a belt 34. The reducer 32 is connected to the drive motor 31. One end of the rotor shaft 22 and the output end of the reducer 32 are respectively connected to the pulleys 33, and the two pulleys 33 are connected to each other by the belt 34. The drive motor 31 is a servo motor. By using the belt 34 and pulleys 33, the position of the motor and reducer 32 is changed from the conventional drive arrangement where they are collinear with the rotor shaft 22 to being placed below the container 1, reducing the overall footprint.

[0051] In one embodiment, refer to Figure 3 As shown, a first sealing element 44 is provided at the bottom end of the vessel lid 41 for sealing the vessel lid 41 and the container 1. A vacuum-resistant bellows 45 is provided between the top end of the vessel lid 41 and the upper bolt 43 to maintain a seal between the vessel lid 41 and the upper bolt 43. The vacuum-resistant bellows 45, through the elastic deformation of the metal bellows structure, maintains airtightness while achieving a seal when the upper bolt 43 is displaced, effectively avoiding the risk of leakage caused by the movement of the upper bolt 43. The container 1 includes two parts connected by bolts 13 along the radial direction of the rotor shaft 22, and a second sealing element 12 is provided at the joint.

[0052] Reference Figure 4 As shown, a first sealing element 44 is provided between the container 1 and the lid 41, a second sealing element 12 is provided at the joint of the two parts of the container 1, and a vacuum-resistant bellows 45 is provided at the relative moving parts of the lid 41 and the top bolt 43. The triple sealing structure works together to effectively prevent gas leakage and the intrusion of external oxygen and water vapor, ensuring the long-term stable operation of the equipment in a vacuum or low-oxygen environment, and meeting the mixing requirements of atmosphere-sensitive materials such as electrode materials.

[0053] In one embodiment, refer to Figure 1As shown, the internal mixer also includes a transmission support 5, with the container 1 mounted on the top of the transmission support 5, and the two drive mechanisms 3 respectively mounted on the side ends of the transmission support 5. Specifically, the drive motor 31 and the reducer 32 are arranged on the side of the container 1 and connected to the rotor shaft 22 via a pulley 33. The transmission path is compact and reasonable, reducing the overall height and floor space of the equipment.

[0054] In one embodiment, refer to Figure 6 As shown, it also includes a worktable 6, on which a linear guide rail 61 is provided. The transmission bracket 5 is slidably connected to the linear guide rail 61, and a receiving box 62 is provided on the worktable 6 at the bottom of the transmission bracket 5. Because the transmission bracket 5 is set on the linear guide rail 61 on the surface of the worktable 6, the container 1 moves smoothly with low resistance and high positioning accuracy.

[0055] In one embodiment, refer to Figure 7 As shown, the internal mixer also includes a cover 63 covering the drive mechanism 3 and the linear guide rail 61, which can effectively shield the transmission components such as the pulley 33 and belt 34, preventing operators from accidentally touching them and causing safety risks. At the same time, the cover 63 can cover the linear guide rail 61, which can prevent dust and extend its service life.

[0056] In one embodiment, refer to Figure 1 As shown, a hinge 14 is provided between the container 1 and the lid 41. The downward pressure drive device 42 is a hydraulic cylinder. In addition, the internal mixer is also equipped with a heat transfer oil circulation pipeline component 7, which can heat or cool the container 1, the top plug 43 and the rotor 21 to ensure that the material is in the required temperature range during the mixing process, improve the mixing uniformity and avoid thermal degradation.

[0057] The working principle of this utility model is as follows:

[0058] The two containers 1 are locked together by bolts 13. The top lid 41 of container 1 is opened, the material is added, the lid 41 is closed and locked, and the downward driving device 42 (hydraulic cylinder) pushes the top bolt 43 down to press the material. The two drive motors 31 are started to drive the rotor 21 to rotate through the pulley 33 and the rotor shaft 22. The two drive motors 31 can be adjusted at different speeds to explore the effect of the rotor 21 speed ratio on the material. After the mixing is completed, the front and rear containers 1 are separated, and the rotor 21 is rotated slowly. The material falls into the receiving box 62 on the workbench 6 under the action of the rotor 21 and gravity.

[0059] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
