Description

Technical Field

[0001] The utility model relates to the technical field of crushing and mixing equipment, in particular to a high-speed plowshare type sludge crushing and mixing machine. Background Art

[0002] In the process of domestic waste recycling, composting, sludge treatment, etc., crushing and mixing a variety of materials is a very important link. If the materials are not crushed and mixed evenly, it will affect the work efficiency of the next processing step.

[0003] At present, the main mixing equipment is screw ribbon or blade type. Screw ribbon mixing equipment is divided into horizontal single screw and horizontal double screw. The mixing mechanism of double screw horizontal mixing equipment is mainly based on the shearing action of the screw ribbon. Its two screws are in opposite directions. When mixing materials, the two screw ribbons stir the materials up and down at the same time. The inner and outer screw ribbons also make the materials move axially in opposite directions. Therefore, the materials form axial reciprocating motion in the mixing chamber. This type of mixing equipment has a strong stirring effect on the material. In addition to the distribution effect, it also has some dispersion effect but it is not intense. The effect of blade type mixing equipment when mixing is not ideal, especially at high speed. The mixing effect and feeding effect of blade type mixing equipment are poor and it is easy to get blocked. Utility Model Content
