[0002] In the wet drawing process of the steel cord production process, the thick copper-plated wire is drawn through a water tank wire drawing machine through different molds and mold chain combinations to produce various fine copper-plated monofilaments required for the next stranding process to produce steel cord. In the existing steel cord drawing process, the soap liquid circulation system is used to cool and lubricate the drawing process. The soap liquid after recycling will have some metal residues or too high metal ion content, so it needs to be treated before it can be reused.

[0003] The current method of recycling soap liquid is to transport the soap liquid in the soap liquid pool to a sedimentation bin for sedimentation and separation, and then filter it through a paper belt filter. Since it is only precipitated and filtered once, the metal residue in the treated soap liquid is not completely treated, and the metal ions in it cannot be treated when the metal ion content exceeds the standard. Summary of the invention

[0024] The last sedimentation bin 2 is connected to the first paper belt filter 3 through a third pipe 10, a third water pump 20 is arranged on the third pipe 10, and the two paper belt filters 3 are connected to each other. After three sedimentation separations, the soap liquid is transported to the paper belt filter 3 through the third pipe 10 under the action of the third water pump 20.
