5L Laboratory Dual-shaft Planetary Vacuum Mixing Machine
Description
The stirring paddle of the instrument is designed as a spiral ribbon stirring paddle, planetary stirring, so as to achieve no stirring dead zone in the mixing barrel, and according to the process requirements, the dispersing disc and revolution stirring use multi-stage speed operation, and the speed and time of each stage can be set set.
Features
1. Made of SUS304 stainless steel, resistant to corrosion by acids, alkalis and organic solvents.
2. Four-blade double-shaft planetary mixing, twist frame mixing blade with high-speed dispersion plate and wall scraping, no mixing dead angle.
3. Low-speed stirring realizes macro-mixing through public and rotation, and high-speed dispersing disc realizes micro-mixing through shearing force.
4. Vacuum environment, effectively eliminate the bubbles generated during the stirring process, the vacuum maintaining effect is good.
5. Multi-stage speed operation can be carried out, and the stirring speed and time of each stage can be set.
6. The slurry bucket lifting design, equipped with spotlights, is convenient for operation, and ensures the safety during the vacuum mixing process.
7. Jacketed mixing tank design, can pass cooling water, suitable for various process requirements, with temperature controller and high temperature alarm system.

|
1-5 mixing principle
|
The low-speed stirring paddle and the serrated
dispersing disc installed on the high-speed dispersion shaft both rotate and
revolve; at the same time, combined with the low-gap design of the stirring
paddle, the low-speed stirring paddle makes the material produce strong
kneading interference motion and up-down/left-right circulation. ; The
high-speed dispersing disc strongly shears and breaks up the materials; thus
finally ensuring that the materials are fully dispersed and evenly blended
(mixed).

limit travel switch, through the specially designed control route, it is
guaranteed that the barrel will stop automatically when it reaches the
specified position.
|
B. During the ascending process of the barrel,
the mixing/dispersing part of the equipment cannot be started. Similarly,
when the machine is running the mixture, the barrel cannot be lowered and the
mixing barrel cannot be opened.
|
C. Use circuit design such as proximity
switches to ensure that the mixing tank cannot be lowered under vacuum.
|
D. The special vacuum buffer tank design can
effectively prevent the vacuum pump oil from returning to the mixing tank.
|
E. The door bolt type buckle is set on the
kettle cover and the mixing barrel to prevent the oil cylinder from falling
automatically.
|
