Abstract

The invention discloses a variable-diameter variable-pitch spiral vertical planetary mixer. The mixer comprises a central screw rod doing fixed-axis rotation, a plurality of planetary screw rods doing planetary motion, a movable scraping plate doing fixed-axis rotation, a planetary gear device and a driving device, wherein a central blade is arranged on the central screw rod, planetary blades are arranged on the planetary screw rods, and the center blade and the planetary blades are variable-diameter and variable-pitch spirals. The mixer is a vertical mixing device which integrates the principles of spiral conveying, planetary motion, gravity and the like, and under the action of the central screw rod, the planetary screw rods, the self-weight and the movable scraping plate, a mixture forms large motion cycles from bottom to top and then from top to bottom while the mixture in the material field also forms a plurality of small motion cycles. According to the mixer, inefficient mixing zones can be effectively reduced, and the mixing efficiency and quality can be improved. Thus, the mixer is suitable for occasions mixing materials such as concrete.

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of mechanical engineering and relates to a helical vertical planetary mixer with variable diameter and variable pitch. [0003] 【Background technique】 [0004] Variable-diameter variable-pitch planetary mixing device adopts multi-helix and planetary motion mixing method, which can fully mix concrete or other mixtures in a short time to meet the quality requirements of material mixing. [0005] At present, the blades of various types of mixers are immobilized, the mixing efficiency is low, and the mixing inefficiency area is large, which greatly affects the quality of concrete mixing and production efficiency. Therefore, a variable-diameter variable-pitch planetary stirring device is proposed. A plurality of variable-diameter variable-pitch stirring screws that perform planetary motion and a variable-diameter variable-pitch stirring screw that rotates on a fixed axis form an agitator together with the container...
