Description

Technical Field

[0001] The present invention relates to the technical field of hydrometallurgy, and particularly relates to a solid-liquid separation device for spongy metal. Background Art

[0002] In the existing hydrometallurgy process, the flocculent spongy metal (such as spongy cadmium, spongy indium, etc.) generated by the displacement process needs to be separated from the displacement liquid through a solid-liquid separation device, and the separated metal material is transferred to the briquetting process.

[0003] The currently commonly used vertical solid-liquid separation tank adopts a filter cloth filtration separation technology, and its typical structure is to set a filter cloth layer in a cylindrical tank body for filtration. Workers need to open the tank cover after filtration and manually take out the spongy metal material deposited on the filter cloth with metal tools. This method has the following significant defects: (1) Poor reliability of the filter cloth structure: During the manual material taking operation, the frequent contact between the metal tool and the filter cloth is likely to cause mechanical damage to the filter cloth, resulting in high filter material replacement costs; (2) High risk in the working environment: During the separation process, hydrogen (H 2 ), hydrogen sulfide (H 2 S), hydrogen chloride (HCl) and other toxic and harmful gases remaining from the displacement reaction are continuously released. Despite the use of forced ventilation and protective masks, workers still face the dual risks of acute poisoning and chronic occupational diseases; (3) Low efficiency of manual operation: The single separation cycle requires continuous high-intensity operation in a closed space for 2 - 3 hours, resulting in reduced labor productivity and the risk of human operation errors. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned prior art, the present invention provides a solid-liquid separation device for spongy metal, which realizes automatic material pushing instead of manual material taking, improves the working environment of workers, and improves production efficiency.

[0006] Furthermore, the filter screen assembly includes a plurality of independent stainless steel filter screen modules, and the stainless steel filter screen modules are detachably connected to the solid-liquid separation box body through bolts.

[0007] Furthermore, a drainage groove is arranged on the bottom side edge of the stainless steel filter screen module on the movable door, and is used to drain the liquid flowing out from the mesh holes to the side of the solid-liquid separation box body.
