Problems solved by technology

The artificial drying method currently used mainly adopts a hot blast stove. The inlet temperature of the circulating air of the hot stove is controlled at about 230 degrees, and the outlet temperature is controlled at about 130 degrees. Evaporation, due to the physical characteristics of gypsum blocks, etc., the surface temperature cannot exceed 80 degrees, otherwise the structure will be damaged, and the drying time is longer, usually 24 hours, and the temperature is not easy to control, and the drying success rate is low

Embodiment Construction

[0017] see figure 2 , the production method includes four steps of batching and mixing 1, forming 2, drying 3 and packaging and warehousing 4, the raw materials used in the production of gypsum hollow blocks are sent into plastic flowing gypsum slurry through batching and mixing 1 water, and the flowing The gypsum slurry is processed into a hollow block of a certain shape by casting 2, and then processed into a finished gypsum hollow block after being dried 3 and packaged and put into storage 4. see you again image 3 , the batching slurry 1 is that the various raw materials for the production of gypsum hollow blocks are transported, extracted and stirred into a uniform mixture according to a certain proportion, stored for use, and then quantitatively measured The mixture, and a certain proportion of The process of high-speed stirring with water to form plastic flow gypsum slurry. The various raw materials for producing gypsum hollow blocks include gypsum, cement and relate...

Abstract

The production process of hollow gypsum block includes four steps of: compounding material slurry, forming, drying and packing. The forming is one automatically controlled stepped course in production units with machines corresponding to material preparation, casting to form and delivery. The control central controls the hydraulic system to drive all the machines in the production units via the gypsum solidifying data collecting control method. The present invention has high product quality, lower water consumption and short drying time.

Description

technical field [0001] The invention relates to a production method of a gypsum block, especially a gypsum hollow block, and related equipment, and belongs to the field of building material production. Background technique [0002] Gypsum block or gypsum hollow block is a block-shaped lightweight wall material made of building gypsum as the main raw material, which is stirred with water, poured and dried. There are gypsum hollow blocks, gypsum solid blocks and gypsum lightweight blocks. Block three categories. Since the gypsum hollow block can effectively eliminate the defects of longitudinal cracks caused by the longitudinal stress, its microporous structure and its staggered masonry can effectively disperse the longitudinal stress and prevent cracks in the wall; and the gypsum hollow block The distribution of single or double rows of holes reduces the weight of the wall and enhances the vertical bending resistance of the block itself; coupled with the sound insulation, he...
