Gypsum board drying online monitoring device and method

Abstract

The invention discloses a gypsum board drying on-line monitoring device and method.The gypsum board drying on-line monitoring device comprises a drying machine, a plurality of drying spaces are formed in the drying machine in the vertical direction, a plurality of lapping rollers used for containing gypsum boards are arranged in the drying spaces, and the gypsum board drying on-line monitoring device further comprises a temperature measuring mechanism used for detecting the temperature of the surfaces of the gypsum boards; the spray head sprays water to the gypsum board to increase humidity when the surface temperature of the gypsum board is too high; and the master controller is used for receiving a signal of the temperature measuring mechanism and controlling the spray head according to the signal. The surface temperature of the gypsum board is monitored when the gypsum board is dried, and water is sprayed to the surface of the gypsum board when the surface temperature of the gypsum board is too high, so that the surface of the gypsum board can be prevented from being overburnt, and the product quality is improved.

Description

Technical field [0001] The invention relates to the technical field of gypsum board production, and in particular to an online monitoring device and method for gypsum board drying. Background technique [0002] Gypsum board is a material made from construction gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, and good sound insulation, heat insulation and fire prevention properties. It is one of the new lightweight panels currently being developed. [0003] In the production process of gypsum board, the drying control process is the most core link, playing a leading role in product quality, production stability, output, molding process adjustment, etc. In recent years, with the continuous improvement of production capacity, the drying process of gypsum board has been gradually shortened, and the drying time is about 30 minutes. Therefore, high temperature and high humidity methods must be adopted to...

Problems solved by technology

[0004] However, in the existing technology, in order to pursue fast drying, the fan will be turned on as large as possible within the rated range. The larger the air volume, the faster the drying, but the problem is that the humidity in the dryer may be low, which may easily cause the surface of the board to dry. Overheating, which affects product quality
