How to improve the stability of melt filter element

Material selection
Multi-layer sintered metal fiber mesh (pore size accuracy 20 microns) or polypropylene (PP) is used. The former is resistant to 300℃ and has zero leakage under 25MPa pressure, while the latter is suitable for liquid filtration and has a pressure resistance of 0.25Mpa/70℃. The gradient pore design can reduce the initial pressure drop by 30% and extend the service life. ‌

Structural design
The double-column alternating operation mode (such as 0.8-second fast switching) is combined with the servo motor to drive the screen changing slide to achieve 72 hours of continuous production; the gradient pore filter can intercept impurities above 0.5μm, and the multi-layer structure reduces pressure loss by 60%. ‌

Cleaning and maintenance
The three-step method of TEG cooking, high-pressure water gun washing and ultrasonic cleaning is used to extend the life of the filter element; the self-cleaning function reduces the generation of waste mesh by 90%, saving more than 800,000 yuan in hazardous waste treatment fees annually. ‌

Temperature and pressure control
The precision control system controls the melt temperature difference at ±1℃, and cooperates with the Internet of Things module to monitor the filter status in real time, predict the best time to change the filter, and improve the material utilization rate by 40%.
