Product Introduction
The plastic centrifugal filter is a device that uses centrifugal force to achieve solid – liquid separation. It is often used in agricultural irrigation, industrial water treatment, and laboratory sample processing fields, which can effectively remove sand, suspended solids and other impurities in water.
Working Principle
- Tangential Water Inlet and Vortex Generation: The impurity-containing water flow enters the conical cavity of the filter at a high speed along the tangential direction, forming a strong rotating vortex. Usually, the inlet water pressure needs to be stable at 0.15 – 0.3MPa to form a sufficient strength vortex field.
- Centrifugal Sedimentation and Impurity Separation: Under the action of the vortex, solid particles with a density greater than that of water are thrown to the inner wall of the conical cavity, and sink to the sand – collecting tank along the wall under the action of gravity.
- Clean Water Rising and Discharging: The clean water after impurity separation forms a low – pressure area in the center of the vortex, and moves upward, and is discharged through the top water outlet.
Product Features
- Efficient Separation: For sand particles larger than 75μm, the separation rate can reach about 98%, which can effectively remove large – particle impurities in water.
- Durable Material: Made of high – quality engineering plastics, such as polypropylene (PP), etc., with strong corrosion resistance, it can operate stably for a long time in complex water quality environments.
- Easy Maintenance: There is no filter screen and detachable parts inside, with a simple structure. There is no need to replace parts frequently. The sand – collecting tank is equipped with a quick – open hand – hole cover, which is convenient for sewage discharge and maintenance.
- Energy – saving and Water – saving: It does not require external power, relies on the self – pressure of the water flow to generate centrifugal force, without additional energy consumption, and the system does not stop flowing during cleaning, saving water.
Technical Parameters
- Working Pressure: Usually up to about 8bar.
- Maximum Flow Rate: Can reach 50m³/h.
- Filtration Accuracy: Generally 70 – 200 mesh.
- Material: The main body is engineering plastic (such as PA, etc.).
Application Scenarios
- Agricultural Irrigation: Suitable for the filtration of well water, river water and other water sources with high sand content, and can be used in various crop irrigation systems such as vegetables, fruit trees, and greenhouses.
- Industrial Water Treatment: It can be used as the protective filtration of cooling tower water, seawater desalination pretreatment, and process circulating water to remove suspended solids and sand in water.
- Laboratory Scenarios: It can be used for the concentration, desalination and buffer exchange of biological samples, such as protein sample processing, which can quickly and efficiently separate and concentrate samples.
