The invention discloses a water recycling device for papermaking equipment. The water recycling device comprises a supporting frame, a stirring tank is fixedly mounted at the top of the supporting frame, a motor is fixedly mounted at the top of the stirring tank, a rotating shaft of the motor penetrates a top plate of the stirring tank and extends to the inside of the stirring tank, one end, positioned inside the stirring tank, of the rotating shaft of the motor is in transmission connection with a stirring shaft through a coupler, stirring rods in uniform distribution are fixedly mounted on the outer surface of the stirring shaft, and an arc-shaped bottom plate is fixedly mounted at the bottom of an inner cavity of the stirring tank. By arranging a recycling tank and a diversion valve, when the stirring tank is washed, washing water and paper pulp are diverted through action of the diversion valve, and used water is pumped into a water storage tank through a second water pump, treatedthrough a filter net, a filter, an adsorber and a water purifier to remove impurities in the water and then recycled, so that environment pollution can be avoided, and water resources can be saved.
