Multifunctional lead bullion electrolytic tank

Abstract

The present invention relates to a multifunctional lead bullion electrolytic tank, comprising a tank body (1), a liquid inlet (2) and an overflow port (3). The tank body (1) is rectangular; the liquid inlet (2) and the overflow port (3) are respectively arranged on the upper parts of two opposite short tank edges; the overflow port (3) is provided with a vertically installed semicircular edge banding baffle plate (4), which is provided with a seal plug (5) on the upper end; surrounding edges and the bottom of the tank body (1) are all composed of a base layer (6), a lining layer (7) and a surface layer (8); the base layer (6) is a cement concrete layer; the lining layer (7) is a phenolic resin layer; and the surface layer (8) is a glass fiber cloth layer. The invention is mainly applied to a wet electrolytic refining technology of lead metal and has good corrosion resistance effect; electrolyte can be directly discharged from the overflow port; and the multifunctional lead bullion electrolytic tank is convenient for repair, and low-cost.

Description

technical field [0001] The invention relates to a multifunctional crude lead electrolytic cell, which is mainly used in the wet electrolytic refining process of lead metal. Background technique [0002] At present, plastics such as reinforced concrete lined with soft PVC and PE are generally used as lead electrolytic cells at home and abroad. However, operational errors in the production process, broken poles due to plate hanging lugs, and other mechanical external forces will cause lead anodes to be damaged. The board breaks the plastic lining, the residual pole smashes the plastic lining, and the plastic lining is broken by external force. Since the plastic lining is laid empty on the concrete substrate, as long as there is a rupture point in the plastic lining, the lead electrolyte will fill the interlayer between the plastic lining and the concrete. , so that the entire inner surface of the concrete tank is corroded. Therefore, the plastic lining is extremely vulnerable...

Problems solved by technology

[0002] At present, plastics such as reinforced concrete lined with soft PVC and PE are generally used as lead electrolytic cells at home and abroad. However, operational errors in the production process, broken poles due to plate hanging lugs, and other mechanical external forces will cause lead anodes to be damaged. The board breaks the plastic lining, the residual pole smashes the plastic lining, and the plastic lining is broken by external force. Since the plastic lining is laid empty on the concrete substrate, as long as there is a rupture point in the plastic lining, the lead electrolyte will fill the interlayer between the plastic lining and the concrete. , causing the entire inner surface of the concrete tank to be corroded

Therefore, the plastic lining is easily damaged, and the degree of damage is large, and frequent maintenance is required, and the maintenance cost is also high.

And when the inner tank is seriously damaged, it will be troublesome to repair, which may lead to the scrapping of the entire electrolyzer and increase the production cost

[0003] In addition, the volume of the lead electrolytic cell in the prior art is relatively large, and when in use, multiple cells are connected in series, and the liquid dosing and rehydration are made from the liquid inlet at one end of the cell, and the overflow at the other end overflows to the next cell; Due to the special requirements of the anode slime of the lead electrolytic cell and the consideration of the reasons for the difficulty of corrosion protection, there is generally no drain port at the bottom of the tank, and when a single tank drains, an acid pump must be used to pump the liquid
