When the planetary carrier of the overhead electric mixer rotates, it drives the two mixing frames and dispersion shaft inside the box to revolve around the axis of the reaction kettle while rotating at high speed, thereby subjecting the material to strong shear and kneading effects, achieving the purpose of full dispersion and mixing;There is a scraper on the planetary carrier that rotates with the carrier, constantly scraping and wiping against the barrel wall to ensure that there is no residual material on the barrel wall and improve the mixing effect. The length of mixing time is controlled by the user based on the properties of the material and can be adjusted through the control panel. The cover and planetary mixer are lifted and lowered by hydraulic pressure, and the operation is flat, fast, and lightweight.
The overhead electric mixer can work under vacuum and continuously discharge water and other volatile substances, making it suitable for use as a degassing kettle. The reaction kettle can be heated or cooled by circulating oil and water as needed; Steam heating can also be used.
The discharge system adopts a hydraulic lifting and pressing tray, which moves downward under the action of hydraulic pressure to press out the material in the bucket. The sealing device of the pressure plate can effectively isolate the air from the rubber material, prevent material from returning, and wipe the barrel wall without retaining any material.
Suitable for experimental fields such as biology, physics and chemistry, cosmetics, health products, food, reagents, etc. It is an experimental equipment for mixing and stirring liquids. The product concept design is innovative, with high torque output during low-speed operation and good continuous performance.
What factors should be considered in the design of a top mounted electric mixer
1. Determine the purpose of stirring: whether it is necessary to achieve process objectives such as heat transfer, absorption, extraction, dissolution, crystallization, etc. for liquid-liquid mixing, solid-liquid suspension, gas-liquid or liquid-liquid dispersion. Select the mixing blade form according to the process characteristics.
2. Calculate the power required for mixing operation: the power required during the mixing process
Reference formula: Power=Power Precision * Liquid Density * 3rd Power of Rotation * 5th Power of Slurry Diameter.
The calculation of power accuracy is complex and related to tank diameter, slurry diameter, blade width, angle, number of layers, viscosity, number of baffles, and baffle size.
3. Choose motor power: Considering efficiency, the calculated value should be greater than or equal to 1.5 times the mixing operation power.
4. Regarding the determination of low street mixing speed: This speed is the low speed that meets the mixing purpose, not the critical speed of the mixing shaft.
5. Select and verify the stiffness and strength of the mixing shaft and propeller based on power.
6. When using a reduction gear, it is also necessary to consider the coefficient of use and the load-bearing capacity of the reduction gear.
7. For slender shafts, additional support, such as middle or bottom support, should also be considered.
8. We also need to consider the installation method (top in, bottom in, or side in), which is determined first.
9. Design support
10. Choose sealing form (packing or machine seal)
