The heating chamber is arranged above the galvanizing tank with a lining, and a heating plate is arranged at the bottom of the heating chamber. Zinc is directly heated by the heating plate for hot-dip galvanizing. Compared with the widely used bottom and side heated steel galvanizing tanks, this galvanizing tank can prevent corrosion and damage of the galvanizing tank and the formation of zinc-iron alloy. Hot-dip galvanizing tanks are usually divided into two categories in terms of the materials used, namely, tanks built with refractory materials and tanks made of steel materials;

[0003] For example, the Chinese authorized patent with announcement number CN214115679U (a hot-dip galvanizing tank for basic parts): includes a hot-dip galvanizing tank body and a bracket, a heating sleeve is provided on the outer side of the hot-dip galvanizing tank body, a chamber is provided inside the hot-dip galvanizing tank body, an upper opening is provided at the top of the chamber, and the upper opening is communicated with the chamber, two sets of stirring devices are symmetrically provided on the left and right sides of the hot-dip galvanizing tank body chamber, the stirring device includes a first connecting frame, a power motor, a first bearing seat, a first gear, a second bearing seat, a second rotating shaft, a third bearing seat, a third rotating shaft and a third gear, the left side of the bottom end of the first connecting frame is connected to the top of the hot-dip galvanizing tank body, and a second connecting frame is provided on the left side of the top end of the first connecting frame, which effectively improves the heating effect of the zinc liquid, improves the convection of the zinc liquid at the bottom of the hot-dip galvanizing tank, reduces the accumulation of zinc liquid at the bottom of the galvanizing tank, improves the galvanizing effect of the basic parts, and improves practicality.

[0004] However, the hot-dip galvanizing tank in the above-mentioned prior art lacks an automatic filling structure. During the galvanizing operation, it is easy for the object to be unevenly galvanized due to the small amount of liquid in the tank, thereby affecting its operating efficiency. Therefore, it does not meet the existing needs. In this regard, we propose a hot-dip galvanizing tank with automatic liquid filling. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model sets a preheating bin on one side above the hot-dip trough, and the preheating bin and the hot-dip trough are connected by a liquid infusion pipe. A zinc block is placed inside the preheating bin to be melted first, and then a push plate is pushed to move by a telescopic rod, and liquid enters the hot-dip trough through a filter plate and a liquid infusion pipe, so that the hot-dip trough can be automatically replenished with liquid, and the residue of the melted zinc block can be prevented from entering the hot-dip trough.
