Description

Technical Field

[0001] This utility model relates to the field of electrolytic zinc production technology, and in particular to a waste liquid filtration device for electrolytic zinc production that prevents clogging. Background Technology

[0002] Electrolytic zinc is an important industrial process widely used in the production of metallic zinc. This process uses electrical energy to reduce zinc ions in zinc ore into metallic zinc. The main raw materials for electrolytic zinc are zinc-containing ores, such as sphalerite and zinc ore. The ores undergo a series of pretreatment steps, such as crushing, grinding and flotation, to obtain high-grade zinc concentrate.

[0003] With the development of the times and the continuous improvement of people's living standards, the electrolytic zinc production process generates a large amount of rinsing wastewater during metal stripping and electrode cleaning. The rinsing wastewater contains a variety of heavy metal ions such as zinc, lead, and cadmium. Due to its large volume and high concentration of heavy metals, direct discharge without treatment will have a serious impact on the surrounding environment.

[0004] Most existing wastewater filtration devices for electrolytic zinc production extract heavy metals from wastewater through sedimentation filtration. However, prolonged filtration of wastewater without timely replacement of the filter plates can easily lead to clogging and overflow, thus reducing the filtration efficiency of the wastewater. Therefore, an anti-clogging wastewater filtration device for electrolytic zinc production is proposed to solve the above problems. Utility Model Content
