[0002] The spray room wastewater recovery device is a device used to collect and treat wastewater generated by spray rooms (such as industrial spray workshops or car washes). Its purpose is to reduce water waste, reduce sewage discharge costs and reduce pollution to the environment.
[0003] At present, when spraying metal parts of household appliances, it is necessary to use a high-pressure water gun to flush out the degreasing agent attached to the outer wall of the metal parts. The waste water after flushing is collected in a waste water tank for recycling and utilization. At present, when recycling, most of the metal particles in the waste water are filtered through a filter. However, after a certain period of use, the metal particles will accumulate on the filter, affecting the filtering efficiency of the filter. If the filter plate is cleaned regularly, the recovery device needs to be shut down. Frequent shutdowns to clean the filter will interrupt the recovery process. Therefore, it is necessary to redesign a spray room wastewater recovery device to address the above problems. Utility Model Content
