N-type hot galvanizing dual-purpose automatic production line system layout and implementation method

Abstract

The invention discloses an n-type hot galvanizing dual-purpose automatic production line system layout and an implementation method. The n-type hot galvanizing dual-purpose automatic production line system comprises a incoming material information registration unit, a material unloading area, a loading information management unit, a material pretreatment process pool, a material transmission system, a material inspection system, a material surface treatment system, a material post-treatment system, an unloading information management area, a white part trimming area, an empty hanger return area, a delivery area, an environmental protection system, a master control system and a closed room system; the environment protection system is divided into an acid mist treatment area, a process tankmanagement system, an additive treatment and regeneration system, a waste acid treatment system, a waste heat utilization system, a wastewater circulation treatment area and a waste gas collection andtreatment area. The master control system is divided into a central control system, an information processing system and a power distribution system, the design follows the concepts of integration and modularization, the operation efficiency is improved, the operation cost is reduced, and meanwhile the installation and debugging efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field related to metal surface anticorrosion, and in particular relates to a system layout and an implementation method of an n-type hot-dip galvanizing two-chemical automatic production line. Background technique [0002] The chemical, electrochemical or physical interaction between the metal and its environmental medium causes the deterioration and deterioration of the metal, which is called metal corrosion. Corrosion is very common. From a thermodynamic point of view, except for a very small number of precious metals ( Except for Au, Pt, etc.), the corrosion of general metals is a spontaneous process. It has been realized that the metals used are rarely due to purely mechanical factors (such as tension, compression, impact, fatigue, fracture and wear, etc.) or other physical factors. (Such as thermal energy, light energy, etc.), the destruction of most metal materials is related to its corrosion factors, so the...

AI Technical Summary

Problems solved by technology

[0003] The existing metal surface hot-dip galvanizing anti-corrosion treatment technology has the following problems: the metal surface hot-dip galvanizing anti-corrosion treatment process has a history of more than 170 years, and the traditional hot-dip galvanizing production line has outdated equipment and high labor intensity. Zinc consumption is high and energy consumption is high, and there is no environmental protection equipment to control pollution. The acid mist and white smoke generated during production not only pollute the atmosphere, corrode equipment and workshops, but also harm the health of operators. The rapid development of the hot-dip galvanizing industry has been able to develop on a large scale. At the same time, because of this large-scale development, the competition in the industry has become increasingly fierce. Factors such as the increase in labor costs and the pressure of environmental protection have become huge obstacles for the development of enterprises. troubled
