Abstract
The invention discloses a water circulation system and a circulation method for spray treatment before coating. The original independent water supply of a single spray pool of spray water is converted into circular water supply of three spray pools to form circulation of water supply and replenishment of the spray water. The water is supplied to a front spray pool from a rear spray pool, and the water is supplied and replenished to the front spray pool in sequence, so the water level in each spray pool is kept in a full state, clear water is not required to be directly added into each spray pool while an ideal working water pressure value of a spray water pump is kept, the utilization rate of the clear water is greatly improved, and the purpose of further saving the water is achieved. A water level limiting device for limiting the water level of the added water is arranged, and is used for controlling the opening and closing of a valve device through a control device. Thus, the water level in each spray pool is automatically kept in the full state, and the resource waste phenomenon caused by overflow is avoided. The workload and the labor intensity of the operator are greatly reduced, the working efficiency is favorably improved, and the purpose of improving the production efficiency is achieved.
