Dry and wet composite mixing equipment for power particles

Abstract

The invention discloses dry and wet composite mixing equipment for power particles. The dry and wet composite mixing equipment comprises a wet mixing machine (8) and a dry mixing machine arranged above the wet mixing machine, wherein a dry mixed material outlet of the dry mixing machine (5) is located at a position right above a dry mixed material feeding bucket (8-1) of the wet mixing machine (8). The dry and wet composite mixing equipment further comprises a weighing sensor (6) and a telescopic supporting and fixing seat (7), which are arranged on a bracket (10). A cement admixture and sand are conveyed to a site and subjected to metering, dry mixing and wet mixing in sequence to prepare wet mixed mortar for a building. According to the invention, the dry mixing and the wet mixing are integrated and realized in one piece of equipment, and the dry mixing and the metering are completed in a same container. Because the cement admixture and the sand for preparing the dry mixed mortar are not conveyed in a mixing manner any more, the segregation problem in a dry mixed mortar conveying process is thoroughly solved, and the mortar quality is ensured. In addition, by adopting the dry and wet composite mixing equipment, the sand is unnecessary to dry in advance, so that the energy-consumption cost for drying the sand is reduced on the premise of realizing the commercialized and specialized production and utilization of the dry ready mixed mortar.

Description

technical field [0001] The invention relates to dry-wet composite mixing equipment for powder and granular materials, which is mainly used for storage, transportation and mixing of building premixed mortar. Background technique [0002] At present, in order to protect the environment and improve the quality of construction mortar, my country has begun to enforce the construction of premixed mortar. There are two types of premixed mortar: dry mix and wet mix. The current production and use methods of commercial dry-mixed mortar are: in the dry-mixed mortar manufacturing plant, cement, mineral admixtures, lime or gypsum, additives, and sand after drying (moisture content less than 0.5%) are mixed to make Dry-mixed mortar leaves the factory and is made into mortar by adding water at the construction site. [0003] Dry-mixed mortar is generally transported by back tanker or special dry-mixed mortar transporter. Since dry-mixed mortar is a powdery or granular material, due to ...

AI Technical Summary

Problems solved by technology

When used on site, it needs to be mixed with water. Therefore, the drying process of sand is uneconomical and consumes a lot of energy.
