Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, and in particular to a water reducing agent adding device, a gypsum board production device and a gypsum board production line. Background Art

[0002] The existing ordinary paper-faced gypsum board has been widely used in residences, office buildings, hotels and other places due to its characteristics of light weight, sound insulation, heat insulation, strong processing performance and simple construction method. When producing gypsum board, water reducer is one of the important additives in the production process. Water reducer can maintain the fluidity of the amplified slurry while reducing the water demand. If the water reducer is added in too much amount, the gypsum will harden quickly, lose a certain strength, and affect the product quality; if the water reducer is added in too little amount, the water reduction effect is insufficient, the production water demand is high, the board drying evaporation is high, and the production efficiency is reduced.

[0003] In the current gypsum board production, water reducers are mostly added in a wet manner, that is, a certain concentration of water reducer is prepared in a tank in advance, and then pumped into a mixer to form a slurry after mixing with other ingredients. The advantage of wet addition is that the pumping is stable, but it still introduces excess water. The evaporation of the gypsum board in the subsequent drying process is still high, and the steam carries too much heat to be discharged, and the energy utilization rate is relatively low.
