Industrial Three-Tank Electrolytic Cleaning Machine The industrial three-tank electrolytic cleaning machine is a specialized equipment designed for high-efficiency surface treatment of metal parts, widely used in industries such as automotive, aerospace, electronics, and precision manufacturing. This system integrates three distinct cleaning stages—degreasing, electrolytic cleaning, and rinsing—to ensure thorough removal of contaminants like oils, oxides, and residues from metal surfaces, preparing them for subsequent processes like plating, coating, or welding. 1. Structure and Components The machine consists of three main tanks: - Degreasing Tank: The first stage employs alkaline or solvent-based solutions to dissolve and remove grease, oils, and loose particles from metal surfaces. Ultrasonic agitation or mechanical brushing may enhance cleaning effectiveness. - Electrolytic Cleaning Tank: The core stage uses an electrolytic process where the workpiece acts as an anode or cathode in an electrolyte solution (typically alkaline or acidic). Electrical current generates gas bubbles (hydrogen or oxygen) that mechanically dislodge stubborn oxides and contaminants, ensuring a microscopically clean surface. - Rinsing Tank: The final stage involves deionized or purified water to eliminate residual chemicals, preventing cross-contamination and ensuring a neutral, residue-free surface. Additional components include power supply units, filtration systems, temperature controls, and conveyor mechanisms (for automated part handling). 2. Working Principle The process begins with immersion in the degreasing tank, followed by electrolytic cleaning, where DC current activates electrochemical reactions. The rinsing tank then neutralizes and washes the parts. The entire cycle is adjustable in duration, temperature, and current density to accommodate different materials (e.g., steel, aluminum, copper). 3. Advantages - High Efficiency: Combines chemical and electrochemical cleaning for superior results. - Precision: Removes submicron contaminants, critical for high-end applications. - Eco-Friendly: Reduces chemical waste compared to traditional methods. - Automation Compatibility: Integrates with production lines for continuous operation. 4. Applications Ideal for cleaning gears, bearings, fasteners, and electronic components before plating or painting. It ensures adhesion, corrosion resistance, and longevity of finished products. 5. Maintenance Regular electrolyte replacement, electrode cleaning, and system checks are essential to maintain performance. Modern systems feature real-time monitoring for pH, conductivity, and temperature. In summary, the three-tank electrolytic cleaning machine is a versatile, high-performance solution for industrial surface preparation, combining efficiency, precision, and environmental adaptability.
