At the same time, the scraper frame 1241 can scrape the inner surface of the flocculation tank 110 so that the attached crops on the surface flow into the recessed portion 111. At this time, The pressure pump 250 is used to rotate the liquid in the flocculation tank 110 to the inside of the liquid collecting chamber 211, so that the waste liquid will flow downward through the vertical pipe 221 and pass through the filter cotton 243 inside the filter cylinder 241 for filtering treatment, and then flow into the separation tank 210 and further treated through the discharge pipe. During the treatment process here, the electroplating wastewater can be mixed more evenly, fully and quickly to improve the purification speed. At the same time, since the separator 240 is elastically installed between the connecting piece 220 and the extrusion piece 230 through the spring 234, the separator 240 can be easily replaced after opening the sealing cover 212, which is beneficial to maintain the separation efficiency and filtration quality and is more convenient to use.

[0033] It should be noted that the specific models and specifications of the servo motor 121, the drug pump 131 and the pressure pump 250 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
