Abstract
A paint waste separating and collecting apparatus comprising a separator tank for receiving cleaning water laden with paint waste and discharged from a cleaning device, and a circulating passage for supplying cleaning water stripped of the paint waste from the separator tank to the cleaning device. The apparatus further comprises a first weir for allowing floating paint waste to flow together with overflow water from the separator tank, an auxiliary separator tank for receiving the overflow water from the first weir, a second weir for allowing the floating paint waste to flow together with overflow water from the auxiliary separator tank, a collector vessel for receiving the overflow water from the second weir and separating the paint waste from the overflow water, a recovery tank for accommodating the collector vessel, a first return passage for returning cleaning water stripped of the paint waste from the auxiliary separator tank to one of the separator tank and the cleaning device, and a second return passage for returning cleaning water stripped of the paint waste from the recovery tank to one of the auxiliary separator tank and the separator tank.
