Abstract
In a continuous surface treating method and apparatus with an inline centrifugal separator, an object to be treated is contained in a basket and hung from a hanger of an overhead type and a series of surface treatments of the object is carried out by using a continuous conveyer of a power and free type. By using a hanger attach-detach conveyer, the object is moved from a main conveyer to a sub-conveyer and an excessive treating liquid attached to the object in a previous process is separated by using the centrifugal separator. Then, the object is returned from the sub-conveyer to the main conveyer to perform a next process. The surface treating apparatus includes the rotatable basket for containing the object. When the surface treatment of the object 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 in the previous process into a next process can be prevented and the concentration of the treating liquid in a bath can be maintained to a constant value. As a result, the obtained film thickness becomes uniform and the quality of the object can be improved.
