The present invention discloses a circulatory fluid-supply cleaning system, comprising a first fitted bucket and a second fitted bucket that communicate with each other. The top of the second fitted bucket communicates with a bottom bin. A left end of the bottom bin communicates with the bottom of a vertical mixing bin. Chain wheel shafts on which chains are installed are disposed at both upper and lower ends within the vertical mixing bin, and a soft large stainless steel mesh connected with a small stainless steel mesh is disposed between the two chains. A liquid outlet is disposed at a left side of the vertical mixing bin, and communicates with a cleaning fluid mixing bin. A mixing device is disposed in the cleaning fluid mixing bin. The cleaning fluid mixing bin communicates with a cleaning bin. The cleaning bin comprises an ultrasonic cleaning bin in which an ultrasonic cleaning machine is disposed, and a waste water bin on which a filtering residue removing machine is disposed. The cleaning bin communicates with a clarifying tank that communicates with primary and secondary filters in order, and the secondary filter communicates with the cleaning fluid mixing bin. The system is capable of realizing circulatory supply and recovery of a cleaning fluid, such that the efficiency and quality of cleaning are improved while energy saving and consumption reduction are achieved.
