Description

Technical Field

[0001] The invention relates to the technical field of hot-dip galvanizing tanks, in particular to a hot-dip galvanizing tank for hot-dip galvanizing. Background Art

[0002] Hot-dip galvanizing is to make molten metal react with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. After pickling, the steel parts are cleaned with ammonium chloride and then sent to the hot-dip galvanizing tank for coating. However, the existing hot-dip galvanizing tanks often use only bottom heating or side wall heating during heating, resulting in uneven heating of the zinc liquid in the tank. Although some equipment is equipped with a stirring device, a large-capacity galvanizing tank is required for large-scale hot-dip galvanizing. A single stirring device has a poor effect on accelerating the flow rate of the galvanizing liquid. If more stirring devices are set, a large amount of space in the galvanizing tank will be occupied, which will not only lead to the problem of not being able to galvanize more steel at the same time, but also the problem of steel colliding with the stirring structure.

Use the partition plate to separate the U-shaped frame 1, U-shaped frame 2, and U-shaped tube from the area where the steel is soaked to prevent the galvanized steel from colliding with the U-shaped frame 1, U-shaped frame 2, and U-shaped tube. Use the fixed plate and the slide bar to limit the L-shaped plate so that the L-shaped plate can only slide left and right. Vibrate the L-shaped plate to slide left and right through the electromagnetic vibrator, thereby driving the partition plate to slide left and right, so that the partition plate forms turbulence in the galvanizing tank body, thereby promoting the flow of the galvanizing liquid.

At the same time, the electromagnetic vibrator 23 is turned on to make the L-shaped plate 19 vibrate left and right, thereby driving the partition plate 18 to vibrate left and right. The left and right vibration of the partition plate 18 forms turbulence in the galvanizing tank body 1, thereby promoting the flow of the galvanizing liquid.

[0023] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.
