Phosphated residue treatment system and technology in wire surface treatment production line

Abstract

The invention discloses a phosphated residue treatment system in a wire surface treatment production line. The phosphated residue treatment system comprises a first phosphating cylinder, a second phosphating cylinder and a centrifugal separator, the first phosphating cylinder communicates with an inlet of the centrifugal separator through a first pipeline, a first cam pump and a first solenoid valve are mounted on the first pipeline, the second phosphating cylinder communicates with the inlet of the centrifugal separator through a second pipeline, a second cam pump and a second solenoid valveare mounted on the second pipeline, a liquid outlet of the centrifugal separator communicates with the first phosphating cylinder through a third pipeline and communicates with the second phosphatingcylinder through a fourth pipeline, and a third solenoid valve is mounted on the third pipeline, a fourth solenoid valve is mounted on the fourth pipeline, and aeration pipes are mounted in the firstphosphating cylinder and the second phosphating cylinder.

Description

technical field

[0001] The invention relates to the field of phosphating slag treatment, in particular to a phosphating slag treatment system and a treatment process in a wire surface treatment production line. Background technique

[0002] On the phosphating unit for the surface treatment of metal wires, the heating temperature of the phosphating solution in the phosphating tank is generally controlled above 75°C. The phosphating solution used is generally zinc-based phosphating solution or manganese-based phosphating solution. After reacting with Fe It will produce insoluble ferric phosphate and other insoluble salts - called phosphating slag, which will deposit on the bottom of the tank. If it is not removed in time, it will affect the phosphating effect of metal materials.

[0003] At present, some enterprises adopt the method of sedimentation outside the tank, that is, a phosphating solution sedimentation tank is set up outside the tank, and the phosphating solution in ...
