Description

Technical Field

[0001] This utility model relates to the field of galvanizing wastewater technology, and in particular to a heavy metal ion adsorption and filtration device for galvanizing wastewater. Background Technology

[0002] The galvanizing process generates wastewater containing zinc and other heavy metals, which is highly toxic and difficult to degrade. Adsorbents (such as chelating resins or graphene oxide) need to be added to the wastewater to adsorb the heavy metal ions, followed by filtration to make the wastewater meet the discharge standards.

[0003] However, in existing technologies, suspended solids in wastewater can easily clog the filter pores during wastewater filtration, leading to reduced filtration efficiency. To address this, a heavy metal ion adsorption filtration device for galvanizing wastewater is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heavy metal ion adsorption and filtration device for galvanizing wastewater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heavy metal ion adsorption and filtration device for galvanizing wastewater, comprising a base, two L-shaped fixing columns fixedly connected to the upper surface of the base, a stirring tank fixedly connected to one end of the two L-shaped fixing columns, a connecting column fixedly connected to one side of each of the two L-shaped fixing columns, a filter box fixedly connected to one end of the two connecting columns, a fixing plate fixedly connected to one side of the filter box and having a sliding groove, a cleaning structure provided on the fixing plate, a filter frame slidably connected in the sliding groove, two fixing blocks fixedly connected to one side of the filter frame, each fixing block having a snap-fit ​​hole on one side, and two connecting plates fixedly connected to one side of the filter box, each connecting plate having a quick-release structure;

[0006] The cleaning structure includes a rotating shaft rotatably connected to the bottom of a fixed plate. A first servo motor is fixedly connected to the upper surface of the fixed plate. The output shaft of the first servo motor is fixedly connected to one end of the rotating shaft. A rotating disk is fixedly connected to the bottom of the rotating shaft. A threaded hole is provided at the bottom of the rotating disk, so that the first servo motor drives the rotating disk to rotate through the rotating shaft.

The threaded rod is threaded into a threaded hole. The rotating disk drives the connecting shaft to move through the threaded rod. The connecting shaft drives the moving rod to move through the moving groove. The moving rod drives the cleaning column to reciprocate on the two sliding columns through the push rod. The brush at the bottom of the cleaning column sweeps the suspended matter on the upper surface of the filter box to both sides.

[0009] As a further description of the above technical solution:

[0010] The quick-release structure includes a fixed frame fixedly connected to one side of the connecting plate. A sliding rod is slidably connected through one side of the fixed frame.
