摘要:
In a continuous surface treating method and apparatus with an inline centrifugal separator, an object (W) to be treated is contained in a basket (20) and hung from a hanger (15) of an overhead type and a series of surface treatments of the object (W) is carried out by using a continuous conveyer (10) of a power and free type. By using a hanger attach-detach conveyer (13), the object (W) is moved from a main conveyer (11) to a subveyer (12) and an excessive treating liquid attached to the object (W) in a previous process is separated by using a centrifugal separator (30). Then, the object (W) is returned from the sub-conveyer (12) to the main conveyer (11) to perform the next process. The surface treating apparatus includes the rotatable basket (20) for containing the object (W). When the surface treatment of the object (W) such as a heat exchanger or the like is continuously executed in the conveyer line, a bringing of the excessive treating liquid attached to the object (W) in the previous process into the next process can be prevented and the concentration of the treating liquid in a bath can be maintained at a constant value. As a result, the obtained film thickness becomes uniform and the quality of the object (W) can be improved.
