Rotary Drum Wire Screen (Wedge Wire Cylinder)

The Rotary Drum Wire Screen, also known as a wedge wire cylinder, is a cylindrical screen made from stainless steel V-shaped wires and support rods. Designed for high-pressure filtration and separation applications, this screen features reinforced support rods to enhance structural integrity and withstand demanding operational conditions.

The rotary drum wire screen is equipped with welded flanges or welded rings at the ends for easy and secure installation. Slot sizes and structural configurations can be customized to meet specific material and working condition requirements, ensuring optimal performance in various industrial environments.

This durable and efficient screen is ideal for applications where high-pressure filtration and precise separation are critical.

Working Principle of Rotary Drum Wire Screen

The rotary drum wire screen is mounted on a roller screen machine, where a motor drives internal blades to compress filtration materials. The screen, made from wedge wire, separates particles from liquid during the rotary process. This efficient design allows for effective filtration and separation.

Advantages

- Increased Open Area: Continuous slot openings significantly expand the open area, improving filtration efficiency.
- Anti-Clogging Design: V-shaped wire structures minimize clogging, ensuring smooth, uninterrupted flow and operation.
- Backwashing Capability: Supports backwashing, enhancing the screen's working efficiency and longevity.
- Reinforced for High Pressure: Reinforced rods ensure the screen can handle high pressure during high-speed rotation.
- Corrosion Resistance: Constructed from stainless steel, the screen is resistant to corrosion and rust, ensuring durability and reliability.
- Easy Installation: Welded flange or metal ring ends allow for simple and secure installation.
- Self-Cleaning Efficiency: The screen's smooth surface and high filtering efficiency, coupled with its self-cleaning properties, provide excellent clogging resistance for consistent operation.

Wedge Wire Rotary Drum Screen for Wastewater Treatment

The wedge wire rotary drum screen is designed for efficient solid-liquid separation in various industrial wastewater treatments. This reliable system effectively removes fine particles, with a diameter of 0.05 mm or larger, making it ideal for filtering out solid contaminants. Primarily used for microporous filtration, the wedge wire rotary drum screen separates small suspended impurities such as animal hair, grease, fibers, and paper pulp from wastewater.

Working Principle

1. Wastewater Inflow: The industrial wastewater to be filtered is piped into the rotary drum screen, where it is evenly sprayed onto the rotating wedge wire surface using pressure.

2. Filtration Process: As the wedge wire rotary drum screen rotates, it intercepts and captures suspended solids while allowing the liquid to pass through.

3. Solid Accumulation: With continuous rotation, solid impurities accumulate and concentrate on the screen surface.

4. Impurity Removal: The rotating action gradually removes the trapped impurities from the filter surface. If the impurities form flocs, the screen's rotation helps to clean its surface, maintaining clear pathways and ensuring high filtration efficiency.

This system is ideal for wastewater applications that require consistent and effective removal of fine solid particles, offering both high efficiency and reliability in industrial environments.
