1. Anti-clogging Management
1. Optimizing Feed Design
Adopting an asymmetric flow channel design (e.g., patent ZL202210356789.X) reduces elbow pressure drop by 45%, minimizing the risk of material accumulation.
Regularly clean the feed inlet filter (weekly inspection recommended) to prevent large particles from entering the cyclone tube.
2. Intelligent Monitoring Technology
Install a torque sensor to monitor clogging risks in real time and trigger the backflush system within 0.3 seconds.
Inspect the grit nozzle for wear and replace it if severely worn (recommended every three months).
2. Sealing and Wear Prevention
1. Seal Maintenance
Use a fluorosilicone-modified self-cleaning coating (surface energy ≤18 mN/m) to reduce adhesion and clogging.
During installation, ensure the O-ring is compressed 10-30% and lubricate with silicone grease to prevent scratches. 2. Upgraded Wear-Resistant Materials
High-wear areas (such as the inner wall of the cyclone tube) are coated with tungsten carbide (80μm thick) or 316L stainless steel.
Regularly passivate stainless steel components to prevent cracking caused by chloride ion corrosion.
III. Operating Parameter Control
1. Pressure and Flow Control
Maintain stable feed pressure (fluctuation range ≤10%) to avoid vibration or separation failure caused by sudden pressure changes.
Adjust the number of stages according to starch type (≥7 for potatoes, ≥9 for grains) to ensure separation efficiency.
2. Material Matching
Control feed concentration (recommended ≤15%). Excessive concentration can easily lead to abnormal underflow density or blockage.
Regularly test starch slurry particle size to prevent ultrafine particles (<5μm) from affecting separation performance.
IV. Daily Maintenance
1. Periodic Inspection
Record the inlet and outlet pressure differential daily. Immediately shut down the machine for cleaning if abnormal.
Perform a thorough inspection of cyclone tube wear, seal elasticity, and pipe connections every three months. 2. Seasonal Protection
Drain liquid from equipment in winter to prevent freezing and damage.
During the rainy season, strengthen electrical protection against moisture to avoid the risk of short circuits.
