Filter Press With Filter Cloth Washing System
A filter press with a filter cloth washing system is a filter press that uses water to wash the filter cloth after filtration. It is mainly used to improve the cleanliness of the filter cloth, extend its service life, and ensure filtration efficiency. Its typical application scenarios include sludge dehydration, chemicals, mining, food, papermaking, and other industries.
What is a Filter Cloth Washing Filter Press?
The filter cloth washing filter press is a traditional filter press with a high-pressure washing system added. The spray device is used to fully clean the filter cloth after the filter cake is removed to remove the residual filter residue and sludge and prevent the filter cloth from being blocked or affect the next round of filtering.
Working Principle of Filter Cloth Washing System
Start the cleaning device
After the filter cake is removed, the PLC automatic control system issues a cleaning command, or the cleaning is started manually by a manual button.
Start the spray device
The high-pressure water pump starts and delivers water to the spray system; the spray device moves up and down, and multiple groups of nozzles are evenly distributed, spraying water for cleaning.
Wastewater collection and discharge
The washed residue flows into the receiving tank together with the water flow and enters the sewage treatment system or recycling system through the drainage pipe.
The system resets and prepares for the next cycle
After cleaning, the nozzle returns to the initial position, the filter plate closes, and the equipment enters the next round of the feed filtration process.
Main Features of Automatic Filter Cloth Washing Filter Press
Strong filter cloth regeneration ability: high-pressure washing can effectively remove residues on the filter cloth, avoid clogging, and improve filtration efficiency.
The high degree of automation: the filter cloth cleaning system can be linked with the PLC system, with a high degree of automation and labor-saving.
Extend filter cloth life: reduce mechanical cleaning frequency and reduce filter cloth wear.
Suitable for highly viscous materials: filter cloth washing can quickly clean up filter cloth residues, such as urban sludge, ceramic wastewater and other scenes where filter cloth is easy to clog after filtration.
Automatic Washing Filter Cloth Filter Press VS Ordinary Filter Press
Filter cloth cleaning method: The automatic cleaning filter press has a high efficiency of automatic high-pressure water spray flushing, while the ordinary filter press needs to manually disassemble the filter cloth for cleaning.
Maintenance frequency: The automatic washing filter press has a low maintenance frequency, and the filter cloth remains unobstructed after flushing, reducing blockage. The filter cloth of the ordinary filter press is easily blocked and needs to be frequently cleaned or replaced.
Automation degree: The filter press with filter cloth washing system can be integrated with a PLC system to automatically execute the flushing process. Most ordinary filter presses require manual participation in filter cloth maintenance and adjustment.
Continuous operation capability: The filter cloth of the automatic washing filter press is in good condition for a long time, and the operation is more stable. The filtration efficiency of the ordinary filter press decreases after the filter cloth is blocked, and it needs to be shut down for processing.
