Description

Hot galvanizing pool

Technical Field

The utility model belongs to hot dip galvanized pipe processing field, concretely relates to hot dip galvanizing pond.

Background

The existing galvanizing process comprises hot galvanizing and electrogalvanizing, and the galvanizing zinc coating effect is inferior to that of the hot galvanizing, so most manufacturers adopt hot galvanizing processing. The traditional hot galvanizing process comprises the steps of feeding selection, acid washing, water washing, adding agent, drying, hot galvanizing processing, cooling and blow-drying. In the hot galvanizing process, the steel pipe is put into zinc liquid, and a zinc layer is attached to the outer surface of the steel pipe in a high-temperature state. The galvanizing bath is a common hot galvanizing reaction device, which is literally understood to be a bath containing zinc liquid, and the hot galvanizing processing process can be finished by putting the steel pipe into the bath for a certain time. However, in the actual operation process, impurities float on the surface of the zinc plating tank after working for a certain time, and the steel materials are always stained with the impurities when leaving the tank, so that the quality of processed products is reduced.

The Chinese patent with publication number CN 208328083U discloses a hot galvanizing pool, which comprises a working area, wherein the working area is surrounded by a heat-resistant layer, and a heat-insulating layer, a reinforcing layer and a base are sequentially arranged outside the heat-resistant layer; a plurality of grooves are formed in the inner wall of the heat-resistant layer, and heating strips are arranged in the grooves; the base is provided with a scraping device, the scraping device comprises a support, a guide rail arranged on the support and a scraping plate arranged on the guide rail, the scraping plate is provided with a brush, and the brush is made of high-temperature-resistant stainless steel materials; and waste removing devices are arranged at two ends of the working area and comprise suckers and discharge pipes connected with the suckers. The hot galvanizing pool brushes impurities floating on zinc liquid by arranging the scraper and the brush above the base in a reciprocating motion manner, but the mode has two problems, namely firstly, the impurities are easy to attach to the brush in the reciprocating motion of the brush until the brush stops moving and falls down, so that the impurities are not completely removed; secondly, impurities are stirred into the zinc liquid or only swept to two sides in the moving process of the brush, and complete impurity removal can not be achieved.
