[0015] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0016] Figure 1-2 A lithium iron phosphate washing liquid precipitation device includes a washing chamber 1 for washing lithium iron phosphate, a separation component that can separate the lithium iron phosphate from the washing liquid after washing, and a recovery component that can recycle the washing liquid for reuse, wherein the separation component and the recovery component are both arranged on the washing chamber 1;

[0017] The separation component includes a first component that can separate the supernatant from the bottom sediment, and a second component that can perform secondary separation on the bottom sediment;

[0018] The washing chamber 1 includes an upper clear liquid chamber 2 and a bottom sedimentation chamber 3;

[0019] The first component includes a first electric sliding door 4, which is arranged above the bottom sedimentation chamber 3, and a first sealing rubber ring is provided around the first electric sliding door 4 where it contacts the inner wall of the washing chamber 1;

[0020] The second component includes a first electric sliding door 5, a separation membrane 7 that can separate the bottom sedimentation from the washing liquid, and a recovery basin 6 for recovering the washing liquid. The first electric sliding door 5 is arranged at the bottom of the bottom sedimentation chamber 3, and the recovery basin 6 is correspondingly arranged below the bottom sedimentation chamber 3. The separation membrane 7 is arranged at the mouth of the recovery basin 6. A second sealing rubber ring is provided around the first electric sliding door 5 at the contact points with the inner wall of the washing chamber 1.
