Problems solved by technology

However, most of the existing co-solvent treatment does not have a dedicated co-solvent tank, resulting in incomplete co-solvent treatment and affecting subsequent processes
The waste water after pickling is difficult to be used for other purposes, resulting in a great waste of water resources

Abstract

The invention discloses a high-efficiency hot dip galvanizing production line which comprises a lifting appliance, a zinc pot, an acid washing tank, a water washing tank, a cosolvent tank and a cooling tank. The high-efficiency hot dip galvanizing production line can quickly remove bubbles on the workpiece surface in the workpiece galvanizing process, can gather the zinc ash on the surface before the workpiece is taken out of the zinc pot so as to prevent the adhesive pollution, can enable the reflux motion of the acid liquor in the acid washing tank so as to increase the contact reaction rate between the acid liquor and acid-washed workpiece, can monitor the concentration of the acid liquor in real time, can enable the water washing of the workpiece to proceed more quickly and thoroughly, can enable the contact between the workpiece and cosolvent more uniformly and quickly, can eliminate the influence of the impurities and stains attached to the workpiece surface on the cosolvent treatment so as to effectively ensure the feed quality of the subsequent procedure, and can enable the water cooling heat transfer of the acid washing wastewater for the hot dip galvanizing cooling tank so as to save the water resources and enhance the wastewater utilization efficiency, thereby saving the production cost.

Description

【Technical field】 [0001] The invention relates to the technical field of hot-dip galvanizing equipment, in particular to the technical field of an efficient hot-dip galvanizing production line. 【Background technique】 [0002] Hot-dip galvanizing is to make the molten metal react with the iron substrate to produce an alloy layer, so that the substrate and the coating are combined. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. , and then sent to the hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The principle of hot-dip galvanizing, simply put, is to immerse the cleaned iron parts in the zinc bath through the wetting effect of the flux, so that the steel and molten zinc react...
