The invention concerns a process to recover paint from overspray whereby one collects paint which misses the target object by means of a collector device which is flushed on all side and floor surfaces with circulating water, concentrates the overspray extracted in the overspray-circulating water mixture from the collector device to an overspray content of approx 20%, then feeds the mixture to a filtration chamber in which the water is separated from the reclaimed raw paint, then measures the physical characteristics of the reclaimed paint, compares these with the physical characteristics of the fresh paint, then adjusts the characteristics of the reclaimed paint to the characteristics of the fresh paint material and mixes the reclaimed paint into the fresh paint. The invention also concerns as device to carry out the process.
A device to carry out a process to recycle paint from the overspray occuring in spray painting, comprising a collector device for collecting overspray which is flooded with water-circulating in a closed system, means for concentrating the water overspray mixture in a collection tank, a filtration chamber connected to the collection tank for separating the mixture into water and raw paint, means for feeding the reclaimed water back into circulation, a measuring section (50) for measuring the physical characteristics of the reclaimed paint and comparing it to the physical characteristics of fresh paint, means for feeding the reclaimed paint to the measuring section, a reprocessing unit for adjusting the consistence of the raw paint according to the data determined in the measuring section, and means for mixing the thus reprocessed paint into the fresh paint to be sprayed, wherein the collector device (1) consists of wall surfaces which are made up of rotating segments, whereby the segments are completely flooded with circulating water.
