Abstract

The invention discloses an L-shaped full-closed environment-friendly hot galvanizing production method. The method is characterized in that: acid washing step-by-step automatic operation is implemented by adopting a mechanical hydraulic transmission manner, namely an acid washing workpiece automatic conveying system horizontally or vertically lifts to automatically convey workpieces to be galvanized to specified anti-collision acid washing tanks for acid washing and dust removing treatment step by step according to the multi-tank acid washing technological requirements, and the whole acid washing process is sequentially, progressively and automatically finished according to the technological requirements. The L-shaped full-closed environment-friendly hot galvanizing production method is pollution-free, environment-friendly, low in energy consumption, mechanical and automatic, and has the characteristics of full closure and integration of reclamation and treatment; and by the method, acid washing automation is realized, the labor intensity is furthest lightened, the production efficiency is improved, and the problem of pollution is solved.

Description

technical field [0001] The invention relates to a hot-dip galvanizing production process, in particular to an L-shaped fully enclosed environmental-friendly hot-dip galvanizing production process with a fully enclosed, clean and environmentally friendly mechanized automation. Background technique [0002] At present, most hot-dip galvanizing industries in China have serious environmental pollution. Hot-dip galvanizing has always followed the ancient solvent method, which is backward in technology, primitive in operation, low in automation, high in labor intensity, high in energy consumption, and high in production costs. The workshop adopts an open type, and the waste gas generated in the hot-plating production is directly discharged into the atmosphere, causing air pollution and seriously affecting the environment and human health. With the continuous improvement of my country's industrial level and the country's emphasis on resources and the environment, energy conservati...
