Abstract

The invention relates to an electromagnetic microwave drying device for gypsum boards. The electromagnetic microwave drying device comprises a microwave heating box, wherein an air introduction pipe is arranged at the top of the microwave heating box. Microwave generators are arranged at the top ends of the microwave heating box, and water coolers are arranged at the tops of the microwave generators. The water coolers are communicated with a water pump. Conveying rollers are arranged in the microwave heating box and are in transmission connection with driven wheels and engaged wheels through chains. The driven wheels are in transmission connection with a motor. Temperature sensing probes are arranged on the microwave heating box. The microwave heating box can effectively ensure that microwaves move in the box, the boards can fully absorb microwaves and vapor is evaporated after heat absorption, and thus the purpose of drying the boards can be achieved; the microwaves emitted by the microwave generators can penetrate through the boards and be absorbed by the boards and move uniformly in the box, and the heated faces of the boards are uniform; the dried boards are tidy and free of expansion deformation, and the forming rate is greatly increased; no gas polluting the atmosphere is generated, and thus the electromagnetic microwave drying device is environmentally friendly, safe and low in energy consumption.

Description

technical field [0001] The invention belongs to the technical field of heating and drying devices, and in particular relates to an electromagnetic microwave drying device for gypsum boards. Background technique [0002] With the development of the economy, the demand for building board products such as anti-static flooring is increasing. During the processing, the board needs to be dried to remove the moisture in the board. The common drying method is hot air drying or heating. Drying, this drying method is widely used, but there are many disadvantages, such as hot air drying and heating drying need to use coal combustion or electric heating, which pollutes the environment and consumes a lot of electricity, resulting in the production cost of the product High, the market competitiveness is low; moreover, this drying method takes a long time and the work efficiency is low; the most important thing is that the traditional drying method is not easy to control the heating area d...
