Embodiment 1

[0043] Battery precursor pressure filter washing method, including:

[0044] (1) Pressure filter: The agonized material is delivered to the third through hole 5 of the pressure filter 1 by the tube, and then sequentially passed through the third through hole 5, the eighth through hole 10 input pressure filter box 1 And the hydraulic device of the filter machine is pressed by pressing the filter plate. At this time, the first through hole 3, the second through hole 4 is closed, and the valve 13 of the four-way tube 13 connected, the filtered mother liquor is removed from On the other side of the pressure filter 1, the ninth through hole 11 is sequentially flowed out, and then the discharge tube is discharged through the mother liquor discharge tube, and the other part is sequentially subjected to the tenth hole 12 from the other side of the pressure filter 1. The five through hole 7 flows out, and then discharged through the mother liquor discharge tube; wherein the apparent materi...

Abstract

The invention discloses a filter pressing and washing device for battery material precursor and a method adopting device. The device comprises a filter pressing box and a plurality of filter pressing and washing plates; the plurality of filter pressing and washing plates are vertically arranged in the filter pressing box; a first through hole, a second through hole, a third through hole, a fourth through hole and a fifth through hole are formed in the side wall of one side of the filter pressing box; the third through hole is located in the center of the side wall of the filter pressing box, and the first through hole, the second through hole, the fourth through hole and the fifth through hole are evenly and symmetrically distributed in the four corners of the side wall of the filter pressing box with the third through hole as the center; a sixth through hole, a seventh through hole, an eighth through hole, a ninth through hole and a tenth through hole which correspond to the first through hole, the second through hole, the third through hole, the fourth through hole and the fifth through hole in position and are communicated with one another are formed in the filter pressing and washing plates. By adopting the device, sodium and sulfur can be quickly removed, washing water can be reduced, the productivity can be improved, and energy consumption can be reduced.

Description

Technical field [0001] The present invention relates to the field of pressure-filtration washing techniques, and more particularly to a pressure filter washing apparatus for a precursor of a battery material and a method thereof. Background technique [0002] Currently, for the mixed product precursor BET (specific surface area) at 16m 2 / g above, the existing washing method causes Na, S washing difficult, water consumption exceeds 18M 3 / t, the washing effect Na, S is uneven, which restricts production capacity. Inventive content [0003] In response to the above prior art, the present invention provides a pressure filter washing apparatus for a precursor of a battery material and a method thereof, rapidly removing sodium sulfur adsorption and reduces the washing water, and enhances capacity, and reduces energy consumption. [0004] The present invention is achieved by the following technical solutions. [0005] A pressure filter washing apparatus for a precursor of a battery...
