Description

Technical Field

[0001] The utility model relates to the technical field of applying natural cold water, such as ordinary tap water, and in particular relates to a water tank conveying device in the production of hot-dip galvanizing of steel pipes. Background Art

[0002] As we all know, in the hot-dip galvanizing production of steel pipes so far, the surface of the steel pipe is moved horizontally and transferred to the water trough device, and then transferred to the water trough gear disc through the slide to the cooling bed frame, or directly into the water trough and transferred to the cooling bed frame by a chain.

[0003] Until now, the traditional method used by hot-dip galvanizing companies for steel pipes has involved transferring the galvanized pipe to a water tank via a horizontal conveyor. The water tank then lowers the pipe into a chute, where it can collide with the chute. The pipe then slides down the chute to the water tank's gear plate, where it can collide with the gear plate. Although the inner ring of the gear plate is equipped with a fluorine plate to prevent the pipe from colliding, the quality issues of marking and pitting at the collision site remain. During these process steps, the energy transfer is not effectively converted and eliminated, resulting in surface quality issues such as markings and pitting on the galvanized pipe.
