Dewatering device

The invention relates to the technical field of Chinese art paper production, in particular to a dewatering device. The device comprises a tank body with a cavity, the cavity of the tank body is communicated with a vacuum environment through an air suction pipe, the upper end of the tank body is opened, goods supporting grids are distributed at the upper end of the tank body, and air-permeable pads are horizontally laid on the goods supporting grids. According to the technical scheme, the dewatering device has the advantages that negative pressure is formed in the tank body through a vacuum pump, then the dewatering process of Chinese art paper is accelerated through a 'suction filtration' principle, and the dewatering efficiency of Chinese art paper is effectively improved. 本发明涉及宣纸生产技术领域，具体涉及种脱水装置；包括具有空腔的箱体，所述箱体的腔室通过抽气管与真空环境连通，箱体的上端呈敞口且布设有托物格栅，托物格栅上平铺有透气垫；采用上述技术方案产生的有益效果在于：通过真空泵使箱体内形成负压，进而通过"抽滤"的原理来加快宣纸的脱水过程，有效提高了宣纸的脱水效率。
