Water-based cutting fluid filtering and deoiling device

The utility model provides a water-based cutting fluid filtering and deoiling device which comprises a cutting fluid tank and a pump, a first impurity filter is arranged at the bottom of the cutting fluid tank, the first impurity filter is connected with a second impurity filter after passing through the pump, and the filtering precision of the second impurity filter is larger than that of the first impurity filter. An outlet of the second impurity filter is communicated with an inlet of the separation filter, an oil liquid outlet and a cutting fluid outlet are formed in the top and the bottom of the separation filter respectively, the oil liquid outlet is communicated with the oil collecting tank after passing through the oil filter, and the cutting fluid outlet is communicated with the cutting fluid groove after passing through the cutting fluid filter. The device is compact in structure and small in occupied area, after the oil-water separation filter element, the one-way oil guide filter element and the o
