870 Filter Press – Diaphragm Squeeze & Auto Cleaning
Core Function and Advantages
1. Diaphragm Pressing Technology The filter cake is subjected to secondary pressing using an elastic diaphragm (made of rubber or PP material), which significantly reduces the moisture content of the filter cake (reducing it by 10% to 30% compared to ordinary filter presses). Suitable for high-demand scenarios, such as mining, chemical industry, sewage treatment, etc.
2. Water flushing system
High-pressure water cleaning device: Automatically cleans the filter cloth after unloading to prevent blockage and maintain filtration efficiency.
Adjustable parameters: Supports customization of pressure, flow rate and rinsing time, suitable for different material properties.
Energy-saving design: Optional circulating water system, reducing water resource consumption.
3. Efficient Filtration Structure
Filter plate material: Reinforced polypropylene (PP), stainless steel or rubber coating, resistant to corrosion and high pressure.
Filtering area: Customized according to filtering requirements (typically, the area of a single machine ranges from 30 to 150 square meters).
Automation control: PLC system integration, supporting one-click operations such as rinsing, pressing, and discharging.
4. Energy conservation and environmental protection
The diaphragm compression shortens the cycle and reduces energy consumption; water flushing reduces the use of chemical cleaning agents.
Working principle:
1.Feed material filtration stage The materials are pumped into the filter chamber, and the liquid passes through the filter cloth and is discharged, while the solids form a filter cake.
2. Diaphragm compression stage Inject high-pressure water/gas into the diaphragm to squeeze the filter cake and further reduce its moisture content.
3. Discharge Stage The filter plate automatically opens and the dry filter cake falls off.
4. Water flushing stage Automatic high-pressure water flushing of the filter cloth to prevent clogging.
How to choose the right model?
- What is the liquid that needs filtering?
2. What is the flow rate?
3. Temperature/PH value?
4. What are the main solid impurities that need to be filtered from the liquid? What is their content?
We can make recommendations based on this information.
