Product Information
As an efficient Rotary Bar Screen for Wastewater, the CF rotary solid-liquid separator is the first line of defense in the pre-treatment stage of municipal and industrial wastewater. Using a continuous rotating rake chain, it automatically lifts plastics, fibers, wood blocks, and other floating or suspended solids from the inlet channel and discharges them into a trash bin. It separates debris thoroughly and runs fully automatically, greatly reducing the labor intensity and safety risks of manual cleaning.

Working Principle
Wastewater flows through the inlet channel and passes through the slowly moving gaps between the rake teeth, where debris is trapped on the screen surface. A motor drives the bottom sprocket, moving the rake teeth in an upward circular motion to scoop up the debris and carry it to the top, where it is unloaded into a collection trough by gravity or a scraper. This Rotary Bar Screen for Wastewater typically features differential level control; when the water level difference reaches the set point, it automatically starts cleaning, and stays on standby when no debris is present, achieving energy-saving operation.
Application Fields
1.Domestic sewage pumping stations: intercepting sanitary products and hair to prevent pump entanglement.
2.Landfill leachate plants: separating plastic bags and fibers to protect downstream processes.
3.Beer and beverage plants: recovering malt residue and packaging fragments to prevent pipe clogs.
4.Woolen and leather plants: intercepting long fibers and fur clumps to reduce biological load.
FAQ
Q1: What is the difference between this Rotary Bar Screen for Wastewater and a standard manual bar screen?
A: Manual screens require frequent raking by workers, which is a harsh environment and low-efficiency. The rotary bar screen is fully automated, runs continuously, and features overload protection. It automatically shuts down and alarms if a large hard object gets stuck, making it safe and efficient.
Q2: What materials are the rake teeth usually made of?
A: The rake teeth and chains are usually made of high-strength engineering plastics (like nylon or POM), stainless steel, or coated carbon steel. Engineering plastics are sufficient for general domestic wastewater—corrosion-resistant and lightweight. For industrial wastewater or water with high grit content, stainless steel is more commonly used.
Q3: How does the anti-jamming function work?
A: The equipment is equipped with a mechanical shear pin or torque limiter. When large objects like sticks, stones, or long fibers get caught in the teeth and cause abnormal resistance, the protection device automatically disconnects or triggers a shutdown alarm, preventing motor burnout or chain breakage.
