Phosphating device with uniform dosing

Abstract

The utility model discloses a phosphating device that adds medicine even, relates to metal material phosphating protection technical field. Through the slag liquid of phosphating tank is purified to the slag removal device and carries out purification treatment, and the phosphating liquid is recycled and is used again, the concentration of the phosphating liquid that enters the phosphating tank has satisfied the requirement to the medicine adding node setting in the purified phosphating liquid, has prevented the concentration of the phosphating liquid in the tank from being uneven to the direct addition of medicine to the phosphating tank, thereby the performance consistency of the metal material surface phosphating film is affected, through the atomization treatment to medicine and clear liquid, the mixture of two is more even, and the concentration of phosphating liquid is more consistent, through the inclination design of atomization nozzle, makes the collision of atomization spouts medicine and clear liquid more intense, and further strengthens the mixing effect.
