Problems solved by technology

If the zinc liquid is not completely removed, it will cool into small zinc nodules in the galvanized pipe, which will affect the quality of the galvanized pipe.
[0003] At present, most of the residual liquid removal devices used for hot-dip galvanized steel pipes can only remove the residual liquid on the outer wall of the steel pipe, because some steel pipes are hollow cylindrical, and there will be residual liquid inside, and the existing residual liquid removal devices cannot achieve internal and external cleaning. The synchronous removal of residual liquid often requires a separate removal equipment, which has certain limitations, and the effect of residual liquid removal is poor, and it also increases the cost of use. For this reason, we propose a residual liquid for hot-dip galvanized steel pipes. Cleaning device and cleaning method

Abstract

The invention discloses a residual liquid removing device for a hot-dip galvanized steel pipe in the technical field of hot-dip galvanized steel pipes. The residual liquid removing device comprises an outer sleeve and an inner sleeve, and the diameter of the outer sleeve is larger than that of the inner sleeve; and residual liquid removing assemblies are arranged in the outer sleeve and the inner sleeve. After the device is installed properly, rolling wheels are driven by electric telescopic rods, so that the top and bottom rolling wheels are tightly attached to the top and bottom inner walls of a steel pipe separately, and then a dual-axis motor is driven; an adjustable telescopic rod is driven by the dual-axis motor through a bevel gear set I, and a moving wheel is driven by the adjustable telescopic rod through a bevel gear set III; therefore, the outer sleeve is moved rightwards on the outer wall of the steel pipe; the outer sleeve is moved rightwards, and the inner sleeve is pulled by a pull rope to move leftwards in the steel pipe, so that residual liquid is synchronously removed inside and outside; and on one hand, the use cost is greatly reduced, and meanwhile the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanized steel pipes, in particular to a residual liquid removal device and method for hot-dip galvanized steel pipes. Background technique [0002] In the existing hot-dip galvanizing process, the steel pipe is immersed in hot-melted zinc liquid, and after the steel pipe is taken out after galvanizing, a large amount of zinc liquid will remain on the steel pipe. If these zinc liquids are not completely removed, they will be cooled into small zinc nodules in the galvanized pipe, which will affect the quality of the galvanized pipe. [0003] At present, most of the residual liquid removal devices used for hot-dip galvanized steel pipes can only remove the residual liquid on the outer wall of the steel pipe, because some steel pipes are hollow cylindrical, and there will be residual liquid inside, and the existing residual liquid removal devices cannot achieve internal and external cleaning. The ...
