Waste water recovery device for machining

The utility model discloses a waste water recovery device for machining, and particularly relates to the field of waste water treatment, which comprises a liquid storage chamber, a communicating pipe,a support plate, a water pump, a drain pipe, a water pumping pipe and a filter tank, damping rods are fixedly connected to two sides of the bottom of the water pump, and damping bases are fixedly sleeved at the bottoms of the damping rods. An air bellow is fixedly installed on one side of the top of the liquid storage chamber, and one side of the top of an inner cavity of the liquid storage chamber is fixedly communicated with a conveying pipe. The air bellow device is arranged, a large amount of water needs to be used for water cooling during machining, waste water needs to be continuously filtered and recycled, and when the water pump works for a long time, the air bellow device automatically conducts air circulation cooling on the environment around the water pump at the moment when the water pump works, so th
