Then, the sewage outlet 31 is opened, and the impurities fall along the bottom surface of the cleaning chamber 21 and through the sewage outlet 31 into the inside of the collection box 32. The reagent box 42 adds oxidant and catalyst into the homogenization and regulation tank 41 to reduce the concentration of the wastewater. While the first stirring shaft 22 drives the second stirring shaft 43 to rotate through the transmission belt 44 to stir the wastewater and the reagent, the first water pump 51 pumps out the wastewater and discharges it again into the homogenization and regulation tank 41 through the first circulation pipe 52, thus circulating to homogenize the wastewater. After the water quality is stable, the reversing valve 53 is opened, and the first water pump 51 pumps out the wastewater and flows it into the flocculation tank 61 through the first circulation pipe 52. The gas inside the bubble generator 62 injects dissolved gas into the homogenization and regulation tank 41 through the dissolved gas pipeline 63 and forms bubbles attached to the suspended solids in the wastewater to realize solid-liquid separation. The slag scraper 81 rotates to scrape the suspended solids into the collection hopper 82. After the separation is completed, the discharge valve 92 is opened, and the wastewater flows into the disinfection tank 91. The disinfection box 94 adds disinfectant into the disinfection tank 91, and the transmission belt 44 drives the third stirring shaft 93 to rotate to stir and mix the wastewater and the disinfectant evenly, so as to achieve the effect of purifying the wastewater. Finally, it is pumped out by the second water pump 71 and discharged into the cleaning chamber 21 again for utilization.

[0057] Compared with the related technologies, a cleaning water tank for the production of recycled plastics provided by the present utility model has the following beneficial effects:

[0058] The present utility model provides a cleaning water tank for the production of recycled plastics. While the cleaning assembly 2 can stir the recycled plastics to wash away the impurities and chemical substances on their surfaces, the sewage discharge assembly 3 can separate the impurities from the wastewater.
