Description

Technical Field

[0001] The utility model relates to the field of filter pressing devices, in particular to a circulating filter pressing device for acid etching tank liquid of aluminum profiles. Background Art

[0002] Aluminum profiles are long strips of material formed from aluminum alloys through extrusion and other processes. They are widely used in construction, transportation, machinery, electronics and other fields. Aluminum profiles have the advantages of light weight, corrosion resistance, good thermal conductivity and strong plasticity. Common aluminum profiles include building door and window profiles, industrial profiles, decorative profiles, etc., which can be customized according to different cross-sections and specifications. They have various processing methods and can meet the design requirements of different application scenarios. They are an indispensable and important material in modern industry and construction.

[0003] Acid etching bath is a chemical solution used for pickling, rust removal and etching of metal surfaces. It is commonly used for the treatment of aluminum profiles, circuit boards, metal products, etc. Its main components are generally concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid and other acid substances. It is highly corrosive and can effectively remove oxide films, impurities and rust on the metal surface. The temperature, concentration and treatment time of the acid etching bath have a great influence on the metal surface effect. Strict control is required during use to avoid damaging the workpiece surface. After treatment, it needs to be cleaned to ensure the smooth progress of subsequent processes.

[0004] After the aluminum profile is acid-etched, the tank liquid will contain the oxide of the aluminum profile. In order to reduce costs, the tank liquid will be added to the filter chamber of the filter press. By applying pressure, the liquid is discharged through the filter cloth, and the solid particles are retained on the filter cloth to form a filter cake. The liquid will be reused to achieve circulation.
