Description

Technical Field

[0001] The invention relates to the technical field of impurity removal, in particular to equipment for rapid impurity removal from lead electrolyte. Background Art

[0002] In recent years, my country's lead smelting capacity and output have grown significantly, further exacerbating structural contradictions in the lead industry and leading to increasingly fierce competition. With the increasing depletion of mineral resources and the continuous increase in lead smelting production costs, many lead smelters have changed their mindsets and are now focusing on high-value-added lead impurities such as high-silver, high-antimony, and high-bismuth raw materials. This produces a lower-grade (around 90%) crude lead with high levels of arsenic, antimony, bismuth, copper, gold, and silver. This is then subjected to electrolytic refining to comprehensively recover the valuable metals and improve the company's overall recovery efficiency. However, existing lead electrolysis technology, for crude lead with high impurities (especially bismuth), causes impurity ions to enter the electrolyte through the wastewater after washing the anode mud during the electrolysis process, resulting in the precipitation of impurity metals at the cathode, causing the electrolytic lead quality to fall below 99.994%.

[0003] Patent document with announcement number CN213113542U discloses a lead electrolyte rapid impurity removal device, comprising a housing, a metal detector, a feed port and a connecting column installed on the top of the housing, a sealing ring clamped on the top of the connecting column, an electrolytic cell liquid inlet pipe clamped on the top of the sealing ring, an acid pump installed at the bottom of the side of the electrolytic cell liquid inlet pipe, the bottom of the acid pump is connected to a waste liquid concentration tank, the top of the waste liquid concentration tank is connected to the electrolytic cell return pipe, the bottom of the electrolytic cell return pipe is installed with a first valve, the side of the electrolytic cell return pipe is connected to a connecting main pipe, the connecting A second valve is installed on the front of the main pipe, a drive motor and a pull plate are installed on the front of the shell, an electrolytic cell is provided inside the shell, an overflow baffle, an anode plate and a cathode plate are installed inside the electrolytic cell, a sedimentation tank and an installation tank are provided at the bottom of the electrolytic cell, a filter is clamped on the top of the installation tank, and a fan blade is installed at the bottom of the installation tank. This document solves the problem that for crude lead with higher impurities (especially bismuth), impurity ions in the electrolysis process are replenished into the electrolyte through the waste liquid after washing the anode mud, resulting in the precipitation of impurity metals at the cathode, causing the quality of the electrolytic lead to be lower than 99.994%.

[0004] However, the above patent documents still have the following deficiencies in practical application:

[0005] The equipment is large in size and has a complex structure. The large size of the equipment easily affects the workers' operation and is inconvenient to use in small factories. Summary of the Invention
