Workpiece quick cooling equipment for hot dip galvanizing

Abstract

The invention discloses workpiece quick cooling equipment for hot dip galvanizing and belongs to the field of hot dip galvanizing. The equipment comprises a base, wherein rollers are fixedly mounted at the bottom of the base, a transverse plate is fixedly connected to the side face of the base, an adjustment screw is arranged inside the transverse plate in a threaded and sleeved mode, an antiskiddisk is fixedly connected to the bottom end of the adjustment screw, a supporting sleeve is fixedly connected to the top of the base, and an adjustment rod is arranged inside the supporting sleeve ina movably sleeved mode. According to the workpiece quick cooling equipment for hot dip galvanizing, through the arrangement of a transmission shaft, a transmission motor, a transmission wheel, a conveying belt, an air conveying sleeve, an air inlet pipe, an air valve and an air outlet cover, in the cooling process of a hot dip galvanizing workpiece, cold air can be conveniently adopted to convey and cool the hot dip galvanizing workpiece, the problem that water resources are prone to waste in the traditional cooling mode of soaking in cold water is avoided, meanwhile the cooling speed of the hot dip galvanizing workpiece is increased, and therefore the working efficiency of hot dip galvanizing workpiece cooling is improved.

Description

technical field [0001] The invention belongs to the technical field of hot-dip galvanizing, and in particular relates to a rapid cooling device for workpieces used for hot-dip galvanizing. Background technique [0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, acid After washing, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip coating tank. After the workpiece is hot-dip galvanized, in order to reduce the surface problems of the workpiece , the workpiece usually needs to be cooled; however, most of the existing hot-dip galvanized workpieces are cooled by immersing the workpiece that has just been hot-dip galvanized in a water ta...

Problems solved by technology

[0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, acid After washing, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip coating tank. After the workpiece is hot-dip galvanized, in order to reduce the surface problems of the workpiece , the workpiece usually needs to be cooled; however, most of the existing hot-dip galvanized workpieces are cooled by immersing the workpiece that has just been hot-dip galvanized in a water tank to cool down, and with the continuous addition of hot-dip galvanized workpieces , the water temperature inside the tank will continue to rise, and the water needs to be changed continuously, which will not only waste water resources, but also delay the cooling process of the hot-dip galvanized workpiece, resulting in low cooling efficiency of the hot-dip galvanized workpiece. For this reason, we propose a rapid cooling equipment for workpieces for hot-dip galvanizing
