Description

A vertical double planetary mixer

Technical Field

The utility model belongs to the technical field of double planetary mixers, and in particular relates to a vertical double planetary mixer.

Background Art

The double planetary mixer is suitable for dissolving, mixing, kneading and reaction processes of materials ranging from powders to high viscosity and high density. Different stirring paddles can be selected according to different production processes and material characteristics. It can also be called a viscous mixer. It is a stirring equipment often used in the production of products such as adhesives, coupling agents, plasticizers and catalysts. Compared with ordinary mixers, it is more efficient and has a wider range of use. The mixer is equipped with a low-speed stirring component and a high-speed dispersing component. The low-speed stirring component adopts planetary gear transmission. The stirring paddle also rotates while revolving, so that the material moves up and down and around, thereby achieving an ideal mixing effect in a shorter time. However, in actual application, it is difficult to achieve the desired mixing effect. When in use, the stirring paddle is usually fixed in position and depth, and its stirring position can be changed by rotation. However, when there is a lot of material in the barrel, the depth of the stirring paddle in the barrel remains unchanged, which will cause the material near the stirring paddle in the barrel to be easily contacted and stirred by the stirring paddle, while the material at a lower and higher position may need to be stirred multiple times before it can contact and participate in stirring with the stirring paddle, affecting the stirring efficiency and effect. In addition, the stirring barrel and the cover body have the function of blocking the material when docked, but the machine will vibrate during operation, which makes it easy for a gap to form between the stirring barrel and the cover body, resulting in material leakage.
