AI Technical Summary
During the pretreatment of centrifugal hot-dip galvanizing of iron nails, a large number of bubbles generated by the chemical reaction gather on the surface of the iron nails, limiting the contact area between the iron nails and the pickling solution, resulting in slowing down the reaction speed, affecting the rust removal effect and subsequent processing steps.
A pretreatment equipment for centrifugal hot-dip galvanizing iron nails is designed. By placing iron nail net baskets in the pickling tank and using a motor to drive the screw and rack system, the iron nail net baskets and support mesh plates swing back and forth, causing the iron nails to swing back and forth, and the bubbles break off the surface and rise and discharge in the pickling tank.
It effectively prevents bubbles from gathering on the surface of the iron nails, restores the contact area between the iron nails and the pickling solution, ensures the rust removal effect of the pickling pretreatment, and does not affect the subsequent processing process of centrifugal hot-dip galvanizing.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hot-dip galvanizing processing, in particular to a device for pre-treating iron nails with centrifugal hot-dip galvanizing. Background Art
[0002] Centrifugal hot-dip galvanizing of nails is a metal surface treatment technology, mainly used for surface anti-corrosion treatment of small metal parts such as nails. The basic steps of this technology include preheating, zinc dipping, centrifugal treatment and cooling. The treated zinc layer solidifies on the surface of the nail to form a solid protective layer. The advantage of centrifugal hot-dip galvanizing is that it can effectively control the thickness of the zinc coating, avoiding the cost increase and processing difficulties caused by too thick zinc coating.
[0003] Before the iron nails are subjected to centrifugal hot-dip galvanizing treatment, the iron nails need to be pretreated, that is, pickling to remove the iron oxide layer on the surface of the iron nails. However, during the pickling pretreatment of the iron nails, a large number of bubbles generated by the chemical reaction will gather on the surface of the iron nails, thereby limiting the contact area between the surface of the iron nails and the pickling solution, which not only slows down the reaction speed of the iron nails and the pickling solution and affects the pickling progress, but also affects the rust removal effect of the pickling pretreatment and affects the subsequent centrifugal hot-dip galvanizing processing procedures. Therefore, an apparatus for centrifugal hot-dip galvanizing pretreatment of iron nails is proposed. Utility Model Content
