Description

Technical Field

[0001] This invention belongs to the field of mixing equipment technology, specifically a double planetary vacuum mixer. Background Technology

[0002] The double planetary mixer is a highly efficient mixing device that integrates dispersion and mixing without dead spots. It combines the principles of traditional double planetary mixers and high-speed dispersers into a versatile new model. The transmission system consists of a low-speed stirring component and a high-speed dispersing component. The low-speed stirring component uses planetary gear transmission; the stirring paddle rotates on its own axis while revolving around the planetary frame, causing the material to move up and down and in all directions, thus achieving the ideal mixing effect in a short time. The high-speed dispersing component revolves around the planetary frame and rotates at high speed simultaneously, subjecting the material to intense shearing and dispersion mixing, with an effect several times that of ordinary mixers. Both the low-speed stirring paddle and the high-speed dispersing head inside the vessel use variable frequency speed control, allowing different speeds to be selected according to different processes and viscosities.

[0003] Traditional mixers typically use single-shaft agitation, which can easily lead to clumping when mixing solids and liquids. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a dual planetary vacuum mixer, comprising a frame, a control box, and a drive unit disposed inside the frame, wherein the control box is mounted on the side wall of the frame, and further comprising: The mixing mechanism is located above the frame, the lifting mechanism is located on the side of the frame near the mixing mechanism, and the material holding mechanism is installed at the bottom of the frame; The lifting mechanism includes a guide rail, a lifting plate slidably mounted on the guide rail, and a movable support disposed below the lifting plate. The guide rail is mounted on the side wall of the frame.

[0005] Furthermore, the stirring mechanism includes: The upper bucket is installed on the side of the frame away from the drive unit. Upper barrel sight glass, wherein the upper barrel sight glass is disposed on the side wall of the upper barrel; The stirring paddle, which is located inside the upper tank, has two paddles and is suitable for mixing, reacting, dispersing, dissolving, homogenizing, and emulsifying liquid-liquid and solid-liquid materials in the electronics, chemical, food, pharmaceutical, building materials, and pesticide industries, such as polymer lithium-ion battery solutions and liquid lithium-ion battery solutions, electronic electrode slurries, adhesives, mold glues, silicone sealants, polyurethane sealants, anaerobic adhesives, inks, pigments, cosmetics, and ointments.

[0006] Furthermore, the stirring mechanism also includes: A dispersing and stirring shaft is symmetrically arranged inside the upper tank. The dispersing and stirring shaft is equipped with a high-speed dispersing toothed disc, which is equipped with a variable frequency speed control function, so that the speed can be adjusted according to the specific production process.

[0007] Furthermore, the material holding mechanism includes: A mixing tank is placed above a movable support, and the mixing tank is positioned coaxially with the upper tank. The rollers are installed around the mixing tank. The rollers installed under the mixing tank can be easily moved to the lifting mechanism after the material is loaded, increasing the flexibility of the equipment.

[0008] The beneficial effects of this invention are as follows: 1. This invention, by setting up a stirring mechanism, moves the material from the inner wall of the mixing tank to the vicinity of the stirring paddle. The stirring paddle can rotate in the same direction as the revolution or in the opposite direction, thereby achieving different shearing effects. In addition, two high-speed dispersing toothed discs with separate power units also rotate in the mixing tank along with the revolution, performing efficient dispersion and emulsification. The high-speed dispersing toothed discs are equipped with frequency conversion speed regulation function, which can adjust the speed according to the specific production process. This unique motion mode can achieve a completely uniform emulsification and mixing effect of the material in a short time, and is particularly suitable for the dispersion and mixing of solid-solid phase, solid-liquid phase, and liquid-liquid phase.

[0009] 2. This invention features a lifting mechanism where the lifting plate and the movable support move upwards along the guide rail, bringing the stirring mechanism placed on the movable support closer to the stirring tank for engagement. The stirring paddle is fixed at the top, and when the tank is lifted, the material contacts the stirring paddle from below, preventing material from splashing onto the main shaft seal, reducing seal wear and contamination risks. The stirring paddle main shaft does not need to descend significantly, resulting in a more stable frame and less vibration during operation. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0013] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a double planetary vacuum mixer, which is described below.

[0014] The system includes a frame 1, a control box 6, and a drive unit 2 installed inside the frame 1. The control box 6 is mounted on the side wall of the frame 1. The system also includes: The mixing mechanism 3 is installed above the frame 1, the lifting mechanism 4 is installed on the side of the frame 1 near the mixing mechanism 3, and the material holding mechanism 5 is installed at the bottom of the frame 1; During operation, after the material filling mechanism 5 is filled with material, it is placed on the lifting mechanism 4. The hydraulic equipment inside the frame 1 lifts the lifting mechanism 4 upward and closes it to the mixing mechanism 3, driving the unit 2 to start, so that the mixing mechanism 3 can mix the material inside the material filling mechanism 5.

[0015] The material holding mechanism 5 includes: The mixing tank 501 is placed above the movable support 403, and the line of the mixing tank 501 is placed coaxially with the upper tank 301. Roller 502 is installed around the mixing tank 501; The rollers 502 installed under the mixing tank 501 can be easily moved to the lifting mechanism 4 after materials are loaded, increasing the flexibility of the equipment.

[0016] The lifting mechanism 4 includes a guide rail 401, a lifting plate 402 slidably mounted on the guide rail 401, and a movable support 403 disposed below the lifting plate 402. The guide rail 401 is mounted on the side wall of the frame 1.

[0017] The hydraulic equipment built into the frame 1 is connected to the lifting plate 402, which moves the lifting plate 402 and the movable support 403 upward along the guide rail 401. This brings the stirring mechanism 3, which is placed on the movable support 403, closer to the mixing tank 501, allowing the stirring mechanism 3 to work. The stirring paddle 303 is fixed at the top. When the mixing tank 501 is lifted, the material contacts the stirring paddle 303 from below, which can prevent the material from splashing onto the main shaft seal, reducing the risk of seal wear and contamination. The main shaft of the stirring paddle 303 does not need to be lowered significantly, making the frame 1 more stable and reducing operating vibration.

[0018] The stirring mechanism 3 includes: Upper bucket 301 is installed on the upper part of the frame 1 away from the drive unit 2; Upper barrel sight glass 302 is installed on the side wall of upper barrel 301; The agitator 303 is located inside the upper tank 301. There are two agitators 303. It is suitable for mixing, reacting, dispersing, dissolving, homogenizing, emulsifying and other processes of liquid-liquid and solid-liquid materials in the electronics, chemical, food, pharmaceutical, building materials and pesticide industries, such as polymer lithium-ion battery fluid and liquid lithium-ion battery fluid, electronic electrode slurry, adhesives, mold glue, silicone sealant, polyurethane sealant, anaerobic adhesive, ink, pigment, cosmetics, ointment and other materials.

[0019] The stirring mechanism 3 also includes: The dispersing and stirring shaft 304 is symmetrically arranged inside the upper tank 301. The dispersing and stirring shaft 304 is equipped with a high-speed dispersing toothed disc, which is equipped with frequency conversion speed regulation function, and the speed can be adjusted according to the specific production process.

[0020] The lifting mechanism 4 lifts the mixing tank 501 close to the upper tank 301. The two parallel stirring paddles 303 rotate synchronously according to a preset fixed rotation ratio. While revolving around the mixing tank 501, they also rotate rapidly on their own axis. At the same time, the rotary scraper set inside the mixing tank 501 also rotates synchronously with the revolution, so that the material moves from the inner wall of the mixing tank 501 to the vicinity of the stirring paddles 303. The direction of rotation of the stirring paddles 303 can be in the same direction as the revolution or in the opposite direction, thereby achieving different shearing effects. In addition, two high-speed dispersing discs with separate power units also rotate within the mixing tank 501 to carry out efficient dispersion and emulsification. The high-speed dispersing discs are equipped with frequency conversion speed regulation function, which can adjust the speed according to the specific production process. This unique motion mode can achieve a completely uniform emulsification and mixing effect of materials in a short time, and is particularly suitable for the dispersion and mixing of solid-solid phase, solid-liquid phase, and liquid-liquid phase.
