Description

Technical Field

[0001] This utility model specifically relates to a structure for the electrolytic recovery and treatment of wastewater sediments. Background Technology

[0002] Electroplating, a crucial process for material protection in the machinery manufacturing industry, generates a large amount of wastewater during production. This wastewater contains not only highly hazardous heavy metal ions such as hexavalent chromium, but also various toxic substances including cyanide compounds, acidic substances, alkaline substances, anti-tarnishing agents, and brightening agents. Direct discharge without effective treatment will cause extremely serious harm to the ecological environment and human health. After treatment, electroplating wastewater produces flocculated precipitates, namely electroplating sludge. Electroplating sludge has an extremely complex composition, originating not only from various chemical reaction products generated during wastewater treatment, but also from the multiple heavy metal ions contained in the wastewater itself, making it a hazardous waste.

[0003] The existing wastewater sediment settles to the bottom of the electroplating tank. After electroplating is completed, it needs to be recycled manually or mechanically. The entire system needs to be shut down to process the sediment, which delays the electroplating process, is inefficient, and manual recycling of sediment is dangerous and can easily cause production accidents.

[0004] Therefore, it is necessary to invent a wastewater sediment electrolytic recovery and treatment structure to solve the above problems. Utility Model Content

[0048] Specifically, the switch plate 7 has a connection hole 72 in the middle, and a sealing cover 73 is installed in the connection hole 72. The bottom of the sealing cover 73 has a handle 76 for easy opening. The switch plate 7 has a pull-out groove 74 on one side, and multiple arc-shaped grooves 75 on one side of the pull-out groove 74 to facilitate pulling the switch plate 7.

[0052] In this embodiment, the screening screen 22 vibrates under the drive of an external motor, which can effectively screen the wastewater sediment at the bottom of the electroplating tank 1, leaving larger particles and impurities on the screening screen 22, while smaller sediments fall into the collection hopper 3 through the screening screen 22, thereby improving the efficiency and accuracy of sediment separation.

[0053] Specifically, the two cleaning plates 63 move synchronously towards the center under the drive of the telescopic motor 61 and the telescopic rod 62. Since the inclined surface 64 at the bottom of the cleaning plate 63 contacts the top of the screening screen 22 and its length and telescopic length can cover the entire screening screen 22, the residual sediment on the screening screen 22 can be thoroughly pushed to the center, preventing the sediment from accumulating and affecting the screening effect, and reducing the amount of manual cleaning work.

[0054] In this embodiment, the sifted and cleaned sediment falls into the collection hopper 3 and then enters the sediment collection box 8 through the adapter 4. The switch plate 7 can flexibly control the opening and closing of the adapter 4, facilitating the control of the sediment collection timing. The fastening bolts 77 can firmly fix the switch plate 7 to prevent sediment leakage. The sealing cover 73 can keep the adapter 4 sealed when sediment is not being collected, preventing odor emission and impurities from entering.

[0055] Specifically, the close fit between the support frame 5 and the electroplating tank 1, as well as the setting of the reinforcing ribs 52, ensure the stability of the entire recycling structure, reduce shaking and vibration during equipment operation, and extend the service life of the equipment.
