Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation mortar production, in particular to a stirring device used for thermal insulation mortar production. Background Art

[0002] Thermal insulation mortar is a premixed dry mortar made of various lightweight materials as aggregates, cement as binder, and some modified additives, which are mixed and stirred by the manufacturer. It is a building material used to construct the thermal insulation layer of the building surface. It can be widely used in dense residential buildings, public buildings, large public places, flammable and explosive places, and places with strict fire protection requirements. It can also be used as a fire isolation belt to improve the fire protection standards of buildings. There are mainly two types of thermal insulation mortars on the market: inorganic thermal insulation mortar (vitrified microsphere fireproof thermal insulation mortar, composite aluminum silicate thermal insulation mortar, perlite thermal insulation mortar), and organic thermal insulation mortar (glue powder polystyrene particle thermal insulation mortar).

[0003] However, the production process of thermal insulation mortar uses many kinds of raw materials, which need to be stirred evenly in the mixing mechanism. The mixing material will adhere to the inner wall of the mixing mechanism, and the solid matter on the inner wall of the mixing mechanism also needs to be removed during the cleaning process. At present, the mixing mechanism used in the production process of thermal insulation mortar mainly focuses on mixing and stirring, but ignores the cleaning of the material attached to the inner wall of the mixing mechanism. Therefore, a new stirring device for thermal insulation mortar production is proposed to solve the above problems. Summary of the invention
