    摘要： A lithium extraction apparatus and a lithium extraction method are provided. The lithium extraction apparatus includes a frame (2) and a transmission mesh belt (1). The transmission mesh belt (1) is installed on the frame (2), the transmission mesh belt (1) has water permeable holes, and the transmission mesh belt (1) is configured to carry an adsorbent. The frame (2) is sequentially provided with an adsorption zone (21) and a desorption zone (22) along a traveling direction of the transmission mesh belt (1). A brine spraying device (211) is arranged above the transmission mesh belt (1) in the adsorption zone (21). A desorbing liquid spraying device (221) is arranged above the transmission mesh belt (1) in the desorption zone (22). A lithium extract collecting device (222) is arranged below the transmission mesh belt (1) in the desorption zone (22). The transmission mesh belt (1) in the adsorption zone (21) is folded into a multi-layer structure in the vertical direction; and/or the transmission mesh belt (1) in the desorption zone (22) is folded into a multi-layer structure in the vertical direction.
