Description

Technical Field

[0001] The invention relates to the technical field of fireproof thermal insulation mortar, and in particular to a fireproof thermal insulation mortar production device and a realization method thereof. Background Art

[0002] Fireproof thermal insulation mortar is a premixed dry mortar made by mixing various lightweight materials as aggregates, cement as binder, and some modified additives. It is used as a building material for constructing the thermal insulation layer of the building surface.

[0003] During the preparation of fireproof and thermal insulation mortar, it is necessary to weigh each raw material according to the proportion of ingredients, add it to the mixing bin for mixing and stirring, and collect the materials after the mixing is completed. Most of the commonly used mixing bins are similar to those of ordinary cement mortar, with an open top. During preparation, the raw materials are directly poured from the top into the mixing bin, and then stirred. After the stirring is completed, the materials can be discharged by driving the mixing bin to rotate and tilt as a whole, or the mortar can be extracted by connecting the extraction equipment to the mixing bin. These increase the preparation operation steps. After a round of mortar preparation is completed, the equipment needs to be paused, and then the mortar is manually discharged, and then new raw materials are added before the next round of mixing and preparation. This not only leads to a large workload, but also low efficiency. Summary of the invention
