Description

Technical Field

[0001] The invention relates to the technical field of aluminum processing, and in particular to a device for treating and purifying electroplating waste liquid for aluminum processing. Background Art

[0002] Aluminum parts refer to equipment components made of pure aluminum or aluminum alloys obtained by casting. Generally, a sand mold or a metal mold is used to pour the heated liquid aluminum or aluminum alloy into the mold cavity. The aluminum parts or aluminum alloy parts of various shapes and sizes obtained are usually called aluminum die castings. Aluminum parts usually need to be processed using various equipment.

[0003] After processing aluminum parts, a large amount of electroplating waste liquid is usually generated. Electroplating waste liquid refers to wastewater containing harmful components such as heavy metal ions, acidic and alkaline substances, and organic compounds generated during the electroplating production process. If these waste liquids are directly discharged into the environment, they will cause serious pollution to water resources and the ecological environment, and even endanger human health. The electroplating waste liquid needs to be purified through a waste liquid treatment and purification device.

[0004] In the process of treating electroplating waste liquid, it is usually necessary to use a filtering mechanism and a purification mechanism to treat the electroplating waste liquid. The impurities in the electroplating waste liquid are filtered out by the filtering mechanism, and the electroplating waste liquid is mixed with the chemical agents in the purification mechanism to purify the electroplating waste liquid. Chemical agents such as Fred salt, which is a layered double hydroxide (LDHs), can remove heavy metal cations and anion pollutants in water through mechanisms such as surface adsorption, interlayer anion exchange and layer plate cation exchange.

[0005] In the process of using filtering mechanisms and purification mechanisms to treat electroplating waste liquid, a filter plate is usually used to filter impurities, and a stirring mechanism is used to stir and mix chemicals and electroplating waste liquid, so that the electroplating waste liquid can be easily filtered and purified. However, after the filter plate filters the impurities, the impurities accumulate on the surface of the filter plate for a long time, affecting the normal use of the filter plate. At the same time, the existing stirring mechanism only uses a single stirring blade for stirring and mixing, and the stirring and mixing rate is slow, resulting in a long purification time, which affects the purification rate.
