The invention discloses a water recycling device used for papermaking equipment. The device includes a rack, a discharging pipe is fixedly connected to the bottom of the rack, a through hole formed inthe lower surface of the rack is communicated with an inner cavity of the rack through the discharging pipe, a purifying box is arranged on the left side of the rack, a first water pump is arranged between the rack and the purifying box and communicated with the discharging pipe through a water pipe arranged at a water inlet of the first water pump, a water pipe arranged at a water outlet of thefirst water pump extends to the top of the purifying box, penetrates through a top plate of the purifying box and extends into the purifying box, and a second water pump is fixedly connected to the left side of the upper surface of the purifying box. Through arrangement of the purifying box, water after use can be purified, not only can waste be reduced, but also pollution caused by direct discharging of the used water can be prevented, environmental protection is facilitated, the cost of papermaking can also be reduced, the structure is simple, and convenience is provided for use.
