How Does the Automatic Filter Cloth Washing System Work?

The filter press filter cloth automatic washing system is an auxiliary device for efficient cleaning of filter cloth. Its core goal is to ensure that the filter cloth maintains good water permeability and filtration performance during continuous operation and to avoid affecting the filtration efficiency due to filter cake residue or blockage. The following are its workflow and components.

Washing System Main Components

High-pressure water pump
Provides strong water pressure to wash the residual filter cake and impurities on the surface of the filter cloth.

Cleaning nozzle (spray rod system)
Installed on the mobile device, it can move along the length of the filter cloth and spray high-pressure water to clean the filter cloth in a full-coverage manner.

Moving guide rail and motor system
Control the nozzle to move at a uniform speed along the surface of the filter cloth to achieve automatic reciprocating flushing.

Control system (PLC)
Set parameters such as cleaning cycle, pressure, time, etc. to achieve fully automatic or semi-automatic operation.
In specific applications, the control system can realize automatic control of all cleaning operations. In addition, the control system has the characteristics of scientific design, convenient operation, and high efficiency. By using the control system, users can complete the scientific setting of relevant parameters through the touch screen according to their actual cleaning needs, and improve the cleaning efficiency and effect.

Working Process of Washing System

Filtration ends, filter plates open
When a filtration cycle is completed, the filter press plate puller pulls the filter plates apart in sequence, and the filter cloth is suspended or stretched to provide space for cleaning.

Start the cleaning program
The control system receives a signal and starts the high-pressure water pump and the nozzle moving device.

Nozzle moving cleaning
High-pressure water is sprayed out through the nozzle in a fan-shaped or straight line, and the cleaning nozzle moves from top to bottom or left to right to fully flush the filter cloth surface.

Wastewater collection and discharge
The washed dirt flows into the drip tray below with the water flow for centralized treatment.

Repeated cleaning (if set)
Multiple cleaning cycles or multiple round trips can be set to ensure that the filter cloth is as clean as new.

Main Advantages

• Extend filter cloth life: reduce the frequency of chemical cleaning and reduce the aging speed of filter cloth.
• Improve filtration efficiency: maintain the permeability of filter cloth and reduce the filter pressing cycle time.
• Save labor costs: automatic operation, eliminating the complex process of manual disassembly and cleaning.
• Reduce downtime: A short cleaning cycle can be automatically operated in conjunction with the filter pressing cycle.

Conclusion

The automatic filter cloth washing system greatly improves the filtration efficiency of the filter press, prolongs the life of the filter cloth, and reduces manual maintenance. It is suitable for sludge treatment, chemical treatment, mining, and other industries.
