Equipment and method for drying gypsum boards

Abstract

The invention provides equipment and a method for drying gypsum boards. The drying equipment comprises a drying device, a conveying device, a humidity discharging device and a control device, wherein the drying device comprises a resonant cavity and a microwave source; the resonant cavity comprises a drying channel; the microwave source is arranged above the resonant cavity; at least one part of the conveying device is arranged in the drying channel; the humidity discharging device is communicated with the resonant cavity; and the control device comprises a temperature and humidity detection unit for detecting temperature and humidity in the resonant cavity, and a control unit which is electrically connected with the temperature and humidity detection unit, the microwave source and the conveying device and controls the power of the microwave source and / or the speed of the conveying device according to the temperature and the humidity. By the equipment and the method for drying the gypsum boards, the gypsum boards to be dried are uniformly put into and pass through the resonant cavity; and meanwhile, the drying temperature and humidity can be monitored, and the humidity-discharging speed of the resonant cavity can be controlled, thus the use ratio of microwaves is improved, drying quality is guaranteed, and the equipment and the method have the characteristics of high drying speed, high efficiency, energy saving, environment friendliness and low cost.

Description

technical field [0001] The invention relates to the field of drying of gypsum boards, more specifically, to a drying device and a drying method of gypsum boards. Background technique [0002] The drying of gypsum board (such as paper-faced gypsum board) is a very important link in the production process of gypsum board, which directly affects the performance and cost of gypsum board. [0003] Drying of gypsum boards (such as paper-faced gypsum boards) in the prior art mainly adopts two methods: [0004] (1) Hot air drying: It uses the heat of boiler flue gas to directly inject boiler flue gas into the hot air pipe of the drying room, and then heats up the heat through the hot air pipe to dry the gypsum board. Although the method of hot air drying has the advantages of low equipment cost and less investment, hot air drying has the disadvantages of long time, high energy consumption and low heat energy utilization rate during the drying process. The quality of gypsum board i...
