Solid-liquid separation structure for electrolytic tank

Abstract

The invention relates to the technical field of waste alloy recovery tungsten carbide electrolysis, and discloses a solid-liquid separation structure for an electrolysis box, the solid-liquid separation structure comprises an electrolytic tank, a partition plate, a lifting mechanism, a lifting support and an electrolysis box, a flow guide plate is embedded in the bottom of the electrolytic tank, flow guide steps are arranged on the upper surface of the flow guide plate, and the flow guide steps are sequentially lowered from left to right; the partition plate is arranged on the upper side of the flow guide plate, the lifting support is arranged on the upper side of the partition plate, guide sliding rods are fixedly connected to the four corners of the bottom of the electrolytic tank, the lifting support is connected with the guide sliding rods in a sliding fit mode, and the lifting mechanisms are arranged on the left side and the right side of the electrolytic tank correspondingly. The lifting bracket is arranged between the lifting mechanisms; the electrolysis boxes are uniformly distributed on the inner side of the lifting bracket; the problem that the production efficiency is affected due to the fact that circulation of an electrolytic solution is blocked and solid-liquid separation is slow in the electrolysis process of preparing a tungsten carbide raw material through an existing electrolytic bath is solved.

Description

technical field [0001] The invention relates to the technical field of tungsten carbide electrolysis for recycling waste alloys, in particular to a solid-liquid separation structure for an electrolysis box. Background technique [0002] At present, the raw materials for the production of tungsten carbide are mainly waste tungsten and cobalt cemented carbide. The common method for recycling tungsten carbide from waste cemented carbide is electrolysis. Titanium mesh is used as the positive electrode, and graphite plate or conductive metal sheet is used as the negative electrode. Electrochemical dissolution is carried out in the liquid, then tungsten carbide is obtained at the positive electrode, and cobalt is obtained at the negative electrode; when the raw materials for preparing tungsten carbide are electrolyzed, the alloy is installed in an electrolytic box with through holes, and then the electrolytic box is placed in Electrolysis is carried out in an acid electrolyte in a...
