Self-Clean Liquid Magnetic Separator with Continuous Operation Automatic Cleaning and Food-Grade Hygiene for Pipeline Iron Removal

The core of the self-cleaning liquid pipeline iron remover is a magnetic rod/magnetic core assembly (permanent magnet or electromagnetic) embedded in the pipeline, combined with an automatic backwashing or scraper cleaning mechanism. When the liquid or slurry flows through the magnetic area in the pipeline, the ferromagnetic impurities are adsorbed onto the surface of the magnet by the strong magnetic field. Once the preset time or pressure difference threshold is reached, the cleaning system will automatically start——Electromagnetic type can be de-magnetized by cutting off the power supply first. Then, through the backwashing water flow or the scraper, impurities are removed and separated. The impurities are discharged through the sewage outlet. The entire cleaning process does not require a shutdown, achieving continuous online iron removal.

Application scenarios

1. Industry of fine chemicals: Continuous removal of iron from coating slurry, pigment suspension, and resin solution to prevent the influence of metallic impurities on the color and stability of the products.
2. The food and beverage sector: Online iron removal for juices, dairy products, sauces and alcoholic beverages complies with food-grade hygiene standards and is suitable for automated filling lines.
3. Pharmaceutical and pharmaceutical manufacturing industry: The removal of iron from liquid medicine, pharmaceutical intermediate solutions, and oral liquid preparations meets the GMP clean production requirements and eliminates impurity contamination.
4. The field of new energy materials: High-precision iron removal for the positive electrode slurry and electrolyte of lithium batteries ensures the purity of battery materials and their electrochemical performance.
5. Water treatment industry: Removal of iron from industrial circulating water, electroplating wastewater and mine water, to protect subsequent pump bodies and heat exchangers.

Advantages and Characteristics

• Continuous operation throughout the entire process: Automatic cleaning does not require downtime, avoiding the disruption of production lines caused by the shutdown and cleaning of traditional pipeline-type iron remover. It is suitable for high-capacity production conditions.
• Clean thoroughly without any blind spots: The combined method of backwashing or scraper and demagnetization (electromagnetic type) can remove the stubborn micron-sized impurities adhering to the surface of the magnet, preventing the attenuation of the magnetic field.
• Easy installation and maintenance: Connected directly to the pipeline system without requiring additional space; the cleaning mechanism has few worn parts and only requires regular inspection of the discharge valve and sealing components.
• Clean and pollution-free: The sealed pipeline structure ensures no material leakage or external contamination, meeting the hygiene requirements of industries such as food and medicine.
• High adaptability: The magnetic field intensity and cleaning cycle can be adjusted according to the viscosity of the liquid and the content of impurities. It is compatible with corrosive liquids (the contact material can be selected as 316 stainless steel).
