Preparation method of dry-mixed mortar

Abstract

The invention relates to a preparation method of dry-mixed mortar. Preparation of the dry-mixed mortar is completed through cooperation of a bottom plate, a protective cover, a feeding device, a vibrating device, an air blowing device and a stirring device. The preparation method of the dry-mixed mortar can solve the problems that when the dry-mixed mortar is manually prepared, raw materials are directly added into a mixing and stirring barrel firstly and then are manually mixed and stirred, the raw materials are difficult to be fully stirred and mixed manually due to the large quantity of the raw materials, manual stirring and mixing are time-consuming and labor-consuming, and consequently the manufacturing efficiency of the dry-mixed mortar is affected, as well as the problems that when existing dry-mixed mortar manufacturing equipment is used for manufacturing, manufacturing raw materials are directly placed in a stirring device at the same time to be mixed and stirred by the stirring device, it is difficult for the stirring device to fully mix raw materials in a relatively small formula proportion with raw materials in a relatively large proportion, and consequently the use effect of the prepared dry-mixed mortar is influenced.

Description

technical field [0001] The invention relates to the technical field of mixed mortar production, in particular to a preparation method of dry mixed mixed mortar. Background technique [0002] Dry-mixed mortar refers to a granular or powdery mixture of aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers) that have been dried and screened in a certain proportion. It is transported to the construction site in the form of bag or bulk, and the dry mix mixture is mixed with water or supporting liquid at the place of use according to the specified proportion. Dry mix mortar is also called dry mix mortar. Some construction adhesives also belong to this category. Dry-mixed mortar is used in the construction industry as a thin layer for bonding, cushioning, protection and decoration. It is widely used in construction and decoration engineering. When making dry mixed mortar, it is necessary to add raw materials according t...

AI Technical Summary

Problems solved by technology

[0004] (1) When the dry-mixed mortar is produced manually, the raw materials are usually added directly to the mixing drum manually, and then the added raw materials are manually mixed and stirred, because the raw materials in the mixing drum are relatively large There are many, which makes it difficult to fully mix the raw materials of dry-mixed mortar manually, and manual mixing is time-consuming and laborious, thus affecting the production efficiency of dry-mixed mortar;

[0005] (2) When the existing dry-mixed mortar production equipment is making dry-mixed mortar, the raw materials are usually directly placed in the stirring device at the same time, so that the stirring device can mix and stir the raw materials. During the stirring process of the stirring device, it is difficult to The raw materials with a small proportion of the formula are fully mixed in the raw materials with a large proportion, thus affecting the use effect of the dry-mixed mortar produced
