Plastic product wastewater purification device

The utility model relates to the technical field of wastewater purification, and discloses a plastic product wastewater purification device which comprises a purification box, a partition plate is fixedly installed at the upper end of the inner side of the purification box, and a filtering assembly and a cleaning mechanism are arranged on the inner side of the purification box. Used waste water is connected with the connecting pipe through the pipeline, then the waste water is introduced into the inner side of the purifying box and flows to the filtering assembly through the through holes, and then the waste water is filtered through the two sets of filter screens of different specifications in the filtering assembly, so that impurity particles of different sizes in the waste water are filtered, and the waste water is purified. Then, an electric push rod is started to drive a push block to move, so that impurities on the surface of the filter screen are pushed to a guide groove to be collected to the inner si
