Novel fountain solution circulating filtration system

The utility model relates to the technical field of offset presses, in particular to a novel fountain solution circulating filtering system which comprises a primary filtering box, a secondary filtering box, a PH adjusting box, a circulating pump and a water purifying box, a centrifugal filtering device is horizontally arranged in the primary filtering box, an extrusion filtering device is arranged in the secondary filtering box, and the PH adjusting box is connected with the circulating pump. The centrifugal filtering device, the extrusion filtering device and the PH adjusting box are communicated through a pressure pump, and the PH adjusting box and the water purifying box are communicated through the circulating pump and the circulating pipe. The fountain solution filtering device has the beneficial effects that the fountain solution filtering treatment efficiency can be improved, the pH value of the fountain solution is debugged, cyclic utilization is realized, the production cost is reduced, and the prod
