Problems solved by technology

The steel pipe treated in this way has uneven adhesion of passivation solution on the surface and poor passivation effect. After wiping with a wipe block, the adhesion of passivation solution is small, and watermarks will be generated when the passivation solution drips downward. , affecting the aesthetics of the steel pipe

Abstract

The invention relates to an automatic spraying system of galvanized pipe passivation liquid. The automatic spraying system is characterized by being composed of a passivation liquid storage box, a filter tank, a spraying base, a spraying cover and atomization spraying mechanisms, a water suction pump is arranged in the passivation liquid storage tank, the upper portion of the spraying base is covered with the spraying cover, openings for a pipeline to pass through are formed in the left end and the right end of the spraying cover, the atomization spraying mechanisms arranged with one above the other are installed on the front cover wall and the rear cover wall of the spraying cover respectively, steam outlets are formed in the two ends of the lower portion of the spraying cover and connected with the inlet of the filter tank through a three-way pipeline, the outlet of the filter tank is connected to the passivation liquid storage box through a pipeline, and a liquid outlet is formed in the bottom of the spraying base and connected to the passivation liquid box through a pipeline connected with a negative pressure machine. The automatic spraying system is scientific and reasonable in structural design, and has the advantages of being uniform in passivation liquid attachment, high in passivation efficiency, capable of ensuring surface attractiveness of steel pipes and reducing passivation cost, convenient to operate and easy to obtain.

Description

technical field [0001] The invention belongs to the field of galvanized pipe production, and relates to processing equipment for galvanized pipes, in particular to an automatic spraying system for passivating liquid for galvanized pipes. Background technique [0002] Passivation treatment is an important step in the production of galvanized steel pipes, the purpose of which is to transform the metal surface into a state that is not easily oxidized. Most of the existing passivation treatment methods are carried out in two steps. First, pass the steel pipe through the box containing the passivation solution, so that the surface of the steel pipe is attached to the passivation solution, and then wipe it with a wipe block. The steel pipe treated in this way has uneven adhesion of passivation solution on the surface and poor passivation effect. After wiping with a wipe block, the adhesion of passivation solution is small, and watermarks will be generated when the passivation solu...
