According to the scheme, the filter comprises a cylinder with a hole, the upper end and the lower end of the cylinder extend outwards along the radial direction to form a circular fixing plate, and through holes are formed in the fixing plate at equal intervals along the circumferential direction; the side surface of the cylinder is provided with a detachable metal net in a surrounding manner, the upper end and the lower end of the metal net are fastened with the cylinder through a pair of semicircular ring-shaped pressing rings, through holes corresponding to the fixing plate are formed in the pressing rings, and the pressing rings are fastened with the fixing plate through screws and nuts; the metal mesh is fixed with the barrel through the fixing strip in the axial direction, the fixing strip is arranged on the outer side of the metal mesh, a plurality of through holes are formed in the fixing strip, through holes corresponding to the fixing strip are formed in the barrel body, and the fixing strip and the barrel are fastened through screws and nuts.

According to the scheme, the adsorbent is a manganese adsorbent.

According to the scheme, the first filter outlet valve and the second filter outlet valve are ball valves.

According to above-mentioned scheme, the through-hole on the fixed strip is the equidistance setting.

The beneficial effects of the utility model reside in that: through set up the different filters of filtration pore size in carrying the lithium tower, can utilize different filters to filter according to the site conditions through the valve that the different filters of control correspond, realize having improved filtration efficiency, reduced the leakage of adsorbent.

Furthermore, the metal net is fixed on the cylinder body of the filter by the compression ring and the fixing strip, and compared with the traditional welding method, the fixing mode is easy to detach and replace.
