Screen Mesh Blockage Cleaning Guide: From Emergency Handling to Long-Term Protection
Screen Mesh Blockage Cleaning Guide: From Emergency Handling to Long-Term Protection
I. Common Causes of Screen Mesh Clogging
As a critical component for material separation, screen mesh clogging is prevalent, primarily caused by:
1.Material Properties Leading to Clogging: Fine powder materials tend to agglomerate due to static adhesion or high humidity; fibrous materials easily become entangled; large particulate impurities directly block openings.
2.Improper Equipment Operation: Insufficient screen tension, improper vibration parameters, or screen deformation/damage.
3.Environmental Factors: High temperatures cause material melting and caking; low temperatures reduce flowability; humidity accelerates adhesion.
II. Targeted Cleaning Methods
Select appropriate methods based on screen material and clogging severity:
- Physical Cleaning Methods
High-pressure air blowing: Use compressed air at 0.4-0.6 MPa to blow diagonally from the back.
Mechanical vibration cleaning: Gently clean using a vibrating platform or soft-bristle brush.
Reverse flushing method: Suitable for liquid screening; flush in reverse with clean water or neutral cleaning solution.
2.Chemical cleaning methods
Acid/Alkali Solution Soaking: Use 5%-10% nitric acid solution for stainless steel screens; neutral detergent for non-metallic screens.
Specialized Descaling Agent: For stubborn blockages, apply industrial-grade descaling agent per instructions.
3.Special Scenario Cleaning Techniques
Fine-Pore Screens (Pore Size <0.1mm): Employ “Freezing + Blowing” method—first freeze, then treat with low-pressure airflow.
High-Temperature Screens: Cool to room temperature before cleaning to prevent thermal deformation.
III. Cleaning Precautions
1.Disconnect power and mark screens before cleaning; handle gently to prevent deformation.
2.Prioritize gentler cleaning methods; avoid hard tools.
3.Thoroughly rinse after chemical cleaning to prevent residue contamination or accelerated aging.
4.Inspect screen integrity and tension post-cleaning; replace damaged components promptly.
IV. Clog Prevention Measures
Material Pre-treatment: Dry high-moisture materials, add anti-static agents, and install pre-treatment screens to remove impurities.
Equipment Maintenance Optimization: Regularly inspect screen tension and vibration parameters, apply anti-adhesion coatings, and establish cleaning schedules.
Environmental Control: Regulate workshop temperature and humidity; employ inert gas protection for oxidizable materials.
This guide enables users to systematically address screen clogging issues, achieving efficient, long-term screen maintenance. Please send the technician to inspect the pump and seal.
