The bottom of each air amplifier 2 is connected to an emulsion reflux tank of the cold rolling mill through a connecting hose.
Six limiting plates 503 are arranged on the fixed base 5, limiting grooves 103 matched with the limiting plates 503 are formed in the rear end of the plane guide plate 1, and the limiting grooves 103 are parallel to the sliding rails 102. When the cylinder rod 401 of the oil cylinder 4 is not fully extended, the limiting plate 503 is partially inserted into the limiting groove 103 at the rear end of the planar guide plate 1 and is positioned on the central line of the limiting groove 103, so that a worker can conveniently observe whether the position of the planar guide plate 1 is deviated or not. Six drainage grooves 104 which are distributed at intervals are further formed in the plane guide plate 1, and the drainage grooves 104 are arranged at positions close to the front ends of the limiting grooves 103, namely the middle of the plane guide plate 1. The front half part of the top surface of the plane guide plate 1 is inclined towards the direction of the drainage groove 104, the inclination gradient is 0.1 percent, and the plane guide plate is mainly used for discharging water drops condensed in the middle of the plane guide plate 1 so as not to influence the concentration of emulsion recovered by the air amplifier 2.
