Problems solved by technology

However, at present, the addition of sulfuric acid is mostly done manually by operators based on experience, which not only consumes manpower, but also tends to cause the risk of production quality decline due to insufficient concentration of sulfuric acid in the electrolyte; in addition, because sulfuric acid is a corrosive liquid, Adding artificially will undoubtedly have certain risks

Abstract

The invention discloses an aluminum profile anodizing device capable of automatically filling electrolyte. The aluminum profile anodizing device is mainly composed of an electrolytic cell, a direct current power supply, a cathode plate, an anode rod and an automatic electrolyte-adding device, wherein the automatic electrolyte-adding device is mainly composed of a sulfuric acid concentration onlinedetector, a controller, a sulfuric acid storage tank, a solenoid valve and a discharging pipe. The aluminum profile anodizing device is capable of automatically controlling the sulfuric acid concentration in the electrolyte, effectively controlling the temperature and uniformity of the electrolyte during the sulfuric acid anodizing process and guaranteeing the smooth proceeding of the sulfuric acid anodizing process; the oxidation effect of aluminum profile is excellent; the formed oxidation film layer is moderate in hardness and higher in porosity of the film.

Description

technical field [0001] The invention relates to an aluminum profile anodizing device capable of automatically replenishing electrolyte. Background technique [0002] The anodic oxidation treatment process is a commonly used surface treatment method for aluminum profiles at present, and the most common one is the sulfuric acid anodic oxidation treatment process. However, during the sulfuric acid anodic oxidation treatment of aluminum profiles, the concentration of sulfuric acid in the electrolyte needs to be maintained at 180-200 grams per liter to obtain an oxide film with moderate hardness and high porosity. However, at present, the addition of sulfuric acid is mostly done manually by operators based on experience, which not only consumes manpower, but also tends to cause the risk of production quality decline due to insufficient concentration of sulfuric acid in the electrolyte; in addition, because sulfuric acid is a corrosive liquid, Adding artificially will undoubtedly...
