Description

Technical Field

[0001] This utility model belongs to the field of solid waste admixture treatment technology, specifically relating to a gypsum-based building solid waste admixture device. Background Technology

[0002] Plaster gypsum mortar is mainly used for leveling and plastering dry interior walls. Compared with traditional cement plaster mortar, it has advantages such as better workability, stronger adhesion, and less susceptibility to cracking and hollowing. The current national standard GB / T28627-2023, "Plaster Gypsum," classifies plaster gypsum mortar into lightweight plaster gypsum and heavy-duty plaster gypsum. Lightweight plaster gypsum has been widely adopted in recent years due to its excellent workability and crack resistance.

[0003] In existing technologies, the common method for mixing gypsum-based building solid waste is to manually spread the material and then spray water for stirring. This method is prone to uneven mixing and difficulty in accurately controlling the amount of material and water added, which leads to a reduction in the efficiency and quality of solid waste treatment.

[0009] Furthermore, the water supply device includes a water supply pipe and a nozzle. The water supply pipe is connected to an external distilled water source, and the nozzle is evenly installed on the side of the water supply pipe that is tangent to the mixing cylinder.

[0010] According to the above technical solution, the beneficial effects of this utility model are as follows: This utility model, through the coordinated work of the mixing drum, stirring device, and water adding device, can efficiently mix gypsum-based building solid waste with admixtures, ensuring uniform mixing, improving material utilization and product quality; the design of the stirring roller and grinding roller in the stirring device can effectively disperse and grind large pieces of material, further improving the mixing effect and ensuring the fineness and uniformity of the material; the water adding device can precisely adjust the humidity of the material, promote the mixing and reaction of the material, and improve production efficiency; the sampling observation window and discharge baffle facilitate operators to monitor the mixing process and control the discharge in real time, improving the flexibility and safety of operation.
