A purification exhaust device based on hot-dip galvanizing production line

Abstract

The invention provides a purification and exhaust device based on a hot-dip galvanizing production line, which includes a reinforced bottom plate, a side temperature insulation plate frame, a galvanizing pool, a heat-conducting conveying frame structure, a side splash-proof frame structure, an air outlet cover, and a top pipe, which can be adjusted. Protective frame structure, longitudinal rod, longitudinal fan, side filter discharge frame structure, console, controller and control buttons, the bolts of the side temperature insulation plate frame are installed on the left and right sides of the upper part of the reinforced bottom plate; The zinc pool is installed on the middle and upper part of the reinforced bottom plate; the heat conduction conveying frame structure is installed on the outside of the galvanizing pool. The positioning grooves of the present invention are set on the left and right sides of the lower part of the bottom cover, which is beneficial to use the lifting cylinder to extend and move the bottom cover downwards, so that the positioning grooves are sleeved on the upper part of the longitudinal baffle, thereby avoiding plating. The gas in the zinc pool leaks to both sides of the longitudinal baffle, thereby improving the protection effect of people passing by on the pedal.

Description

technical field [0001] The invention belongs to the technical field of hot-dip galvanizing, and in particular relates to a purifying exhaust device based on a hot-dip galvanizing production line. Background technique [0002] Hot-dip galvanizing is to make the molten metal react with the iron substrate to produce an alloy layer, so that the substrate 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, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride. , and then sent to the hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. [0003] However, the purification and exhaust device of the existing hot-dip galvanizing production line is inconvenient to protect the upper side of the galvanizing pool when it is ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a purifying exhaust device based on a hot-dip galvanizing production line, to solve the problem that the existing purifying exhaust device of a hot-dip galvanizing production line is inconvenient when not in use and has an effect on the upper side of the galvanizing pool. Protective function, it is inconvenient to heat the heat preservation pool, the liquid is easy to splash when it falls into the galvanized pool, and it does not have the problem of spraying the gas on the upper and lower sides at the same time
