Title: FLOCCULATION WASHING MACHINE AND METHOD FOR CLEANING FLOCCULATION TUB
Abstract:
A flocculation washing machine and a method for cleaning a flocculation tub. The flocculation washing machine comprises a flocculation tub (2) for flocculating washing water. An outer circulation pipe (3) is provided outside the flocculation tub (2). The lower end of the outer circulation pipe (3) is in communication with the bottom of the flocculation tub (2), and the upper end thereof is in communication with the interior of the flocculation tub (2) by means of a spray washing structure. Water in the flocculation tub (2) is enabled to flow in a circulating manner through the outer circulation pipe (3) from the bottom up, and the circulating water is used by the spray washing structure to flush the inner wall of the flocculation tub (2), especially the bottom of the flocculation tub (2), to mix floating floccules with water and then discharge the mixture, thereby thoroughly removing the residual floccules. According to the apparatus and method, the residual floccules on the inner wall of the flocculation tub is flushed by using a small amount of retained water at the bottom of the tub in a circulating manner, and the water is uniformly mixed with the floccules, so that no residual floccules are left on the inner wall and at the bottom of the flocculation tub.
