Reusable Filter Fabric: Extend Lifespan, Reduce Replacement Frequency

1. Thoughtful Selection as a FoundationBased on the particle size, corrosiveness, and temperature of the material, select the appropriate filter cloth. For acidic materials, choose polyester filter cloth; for alkaline materials, choose polypropylene filter cloth; for high-viscosity materials, opt for smooth monofilament filter cloth. This approach helps reduce the likelihood of clogging and damage from the source, thereby extending the base service life.
2. Scientific Cleaning to Prevent DamageAfter unloading, immediately rinse the filter cloth with a high-pressure water gun, maintaining a pressure of 0.3-0.5 MPa to avoid direct impact on the warp and weft lines of the filter cloth. For sticky material residue, soak with a neutral cleaner for 10-15 minutes before rinsing. Sharp tools like steel wool or scrapers are strictly prohibited. Small areas of damage can be repaired with specialized filter cloth adhesive, eliminating the waste of "small damage, immediate replacement."
3. Standardize Storage to Prevent Moisture DamageEnsure that the spare filter cloth is stored in a dry, well-ventilated area, avoiding direct sunlight and damp conditions to prevent hardening and cracking. Inspect the flatness of the filter cloth before use to avoid uneven filtration and accelerated wear due to creases.

Energy Efficiency Optimization: Power Supply on Demand, Reducing Electricity Consumption

1. Hydraulic System Pressure CompatibilitySet the minimum clamping pressure according to the filter plate sealing requirements; just ensure no leakage, no need to blindly increase it; if the equipment is shut down for more than 1 hour, promptly turn off the hydraulic pump motor to avoid idle power consumption.
2. Feed Pump Variable Frequency ControlThe company has upgraded to a variable-frequency feeding pump, which adjusts its speed based on the material filling status of the filter chamber. During the initial feeding stage, the pump operates at high speed for rapid material loading. As the filter chamber approaches full capacity, the speed is reduced to maintain stable pressure, preventing high-pressure overflow and avoiding waste of energy.
3. Peak-shaving water control in the cleaning processConcentrate on cleaning filter cloths during peak hours to avoid frequent startups and shutdowns of the cleaning pump; adjust the cleaning duration based on the degree of filter cloth contamination to prevent "over-washing," and prioritize the use of recycled process water for cleaning to reduce fresh water consumption.
