Multi-stage vibration dryer

The invention relates to a multi-stage vibration dryer. The multi-stage vibration dryer is applied to the technical field of lithium battery raw material drying equipment. The multi-stage vibration dryer comprises a rack and multiple vibration drying boxes. The multiple vibration drying boxes are arranged in the height direction of the rack and elastically connected with the rack, feed ports are formed in the upper portions of one ends of the vibration drying boxes, discharge ports are formed in the lower portions of the other ends of the vibration drying boxes, the discharge ports of the vibration drying boxes communicate with another adjacent feed ports, and electromagnetic heating elements are arranged at the bottoms of the vibration drying boxes. The multi-stage vibration dryer has theeffect that water residues obtained after raw materials are dried are reduced. 本发明涉及一种多级振动干燥机，应用在锂电池原料干燥设备的技术领域，其包括机架和若干振动干燥箱，若干振动干燥箱沿机架高度方向设置并机架弹性连接，振动干燥箱一端的上部设有进料口，另一端的下部设有出料口，振动干燥箱的出料口与另一相邻的进料口连通，各个振动干燥箱的底部均设有电磁加热元件。本发明具有
