Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of lead electrolytic refining, and particularly relates to an electrolytic cell for lead electrolysis. Background Art
[0002] The commonly used method for lead electrolytic refining at present is the one proposed by Betts in 1901. Crude lead or semi-refined lead preliminarily refined by pyrometallurgy is electrolyzed in an electrolytic cell in an aqueous solution environment of fluosilicic acid (H 2 SiF 6 ), and lead fluosilicate (PbSiF 6 ).
[0003] However, there are problems in the use of traditional electrolytic cells: First, the electrolyte used in the Betts method for lead production is fluosilicic acid, which has strong corrosion on traditional cement-cast electrolytic cells; second, for the newly installed anodes or cathodes of the electrolytic cell, due to the relatively thick anodes, when the electrode distance is small, short circuits will occur if they are slightly bent or the electrode plates are installed obliquely. The newly installed cathode plates are too thin and soft. After being placed in the cell, they are easily bent by the impulsion of the circulating electrolyte and come into contact with the anodes, resulting in short circuits. Content of the Utility Model
[0004] Aiming at the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide an electrolytic cell for lead electrolysis that is corrosion-resistant and can avoid short circuits.
[0005] To achieve the above technical purpose, the utility model adopts the following technical solutions:
[0006] An electrolytic cell for lead electrolysis, characterized in that: it includes an inner tank and a cell body. The inner tank is placed inside the cell body, and electrode partitions are evenly arranged inside the inner tank.
[0007] Preferably, the inner tank is made of phenolic epoxy resin material.
[0008] Preferably, the electrode partitions are evenly provided with diversion grooves. An inlet is provided above one side of the inner tank, and an outlet is provided below the opposite side.
[0009] Preferably, a lifting ring is installed above the inner tank.
[0010] Preferably, the cell body is provided with an inlet pipe corresponding to the inlet of the inner tank and an outlet pipe corresponding to the outlet.
[0011] According to the above technical solution, the beneficial effects of the present utility model are as follows: The present utility model provides an electrolytic cell for lead electrolysis with corrosion resistance. The inner tank is made of corrosion-resistant phenolic epoxy resin material, which can effectively protect the tank body from corrosion. The partition plate provided in the inner tank can prevent the electrode plates from short-circuiting due to bending or contact during tank installation. The inner tank is detachably installed, and the inner tank can be taken out when needed, facilitating the cleaning and maintenance of the electrolytic cell. BRIEF DESCRIPTION OF THE DRAWINGS
