TREATING LIQUID CIRCULATION MECHANISM FOR COUPLED CHEMICAL TREATMENT APPARATUS

摘要

PURPOSE:To provide the title circulation mechanism by which sufficient circulation of a chemically treating liquid can be carried out by placing a receiver for the liquid sprayed in two or more chamical treatment apparatus coupled, and feeding the liquid in the receiver to other apparatus through circulation piping owing to a difference in liquid surface. CONSTITUTION:Receiver 9 for chemically treating liquid 2 sprayed 5 is placed in coupled chemical treatment apparatus 1 at a position higher than the surface of liquid 2. Circulation piping 10 is extended from receiver 9 to other coupled apparatus 1 through connection pipe 6. With the constitution, liquid 2 is fed from receiver 9 to apparatus 1 owing to a difference in liquid surface and liquid 2 of the same amt. can be returned through pipe 6. Since spray pump 3 can also be used as a circulation pump, any circulation pump is not required. Piping 10 is all arranged in apparatus 1, and hence the apparatus can be made compact and a liquid leak does not occur.
