摘要:
A method of and an apparatus for applying surface treatment on an object-to-be-treated which is continuously moved in a treating liquid from one end of a treating vessel toward the other end thereof usually by a hanging conveyer. The apparatus comprises an overflow outlet (3a) for the liquid disposed on the incoming end of the treating vessel (3), a overflow tank (6) for reservoiring the overflowed liquid, a return passage (7) for returning the liquid from the overflow tank (6) back to the treating vessel (3), a single or a pair of gush-spraying pipes (5a, 5b) of the treating liquid disposed on the incoming end over the surface fo and/or immersed in the liquid, and at least one gush-spraying pipe (11), disposed on the outgoing end of the treating vessel (3).

摘要:
An apparatus for applying surface treatment on an object-to-be-treated which is continuously moved in a treating liquid usually by a hanging conveyor. The apparatus is provided at the bottom portion of a treating vessel (3, 20, 60) with one or more hoppers (18, 22, 64), which function to collect the deposited sludge for exhausting the same through the lower portion of the hoppers (18, 22, 64) outside the treating vessel (3, 20, 60). Further, the apparatus is provided with a plurality of slant plates (24,68,70) disposed above the bottom of the treating vessel (20, 60), being inclined in the same direction, with a predetermined inter-distance among them, so as to facilitate a sludge produced in the vessel to be gradually precipitated or deposited down on the bottom thereof.
