Compact Structure Rotary Drum Fine Screen Smooth Operation Highly Efficient Screening

Compact Structure Rotary Drum Fine Screen Smooth Operation Highly Efficient Screening

Brief Description

This rotary drum fine screen features an integrated, compact structure, suitable for space-constrained industrial environments. The equipment operates smoothly with minimal vibration, effectively reducing interference with surrounding facilities. It boasts high screening efficiency, reliably intercepting fine suspended solids, and is widely used in food processing, chemical pretreatment, and primary wastewater treatment, serving as a crucial pretreatment device to ensure smooth downstream processes.

Product Overview

Our Rotary Drum Fine Screen is expertly designed for maximum efficiency and stable operation. It provides a complete solid-liquid separation solution for tough wastewater conditions, effectively removing fine suspended solids such as scum, short fibers and particles. The result is clear effluent and compact, dewatered screenings, simplifying downstream treatment and disposal.

Working Principle

Departing from the fragmented design of conventional equipment, this system consolidates interception, cleaning, lifting, and dewatering into a unified unit, forming a fully automated closed-loop operation that drastically streamlines wastewater solid handling processes.
1. Interception
The drum is mounted at an optimal 35-degree angle inside the channel and rotates at a steady speed. Wastewater enters through the inlet port, where fine screen panels intercept and retain solid particles to initiate preliminary solid-liquid separation.
2. Cleaning
As the drum revolves, adhered solids are automatically removed on a continuous basis. A synergistic combination of heavy-duty nylon brushes and a high-pressure spray nozzle system keeps the screen clog-free, ensuring consistent operational performance and throughput capacity.
3. Lifting & Conveyance
Separated solids are directed into an integrated central screw conveyor. This internal spiral mechanism gently lifts screenings upward and out of the water flow to prevent recontamination and backflow.
4. Dewatering & Discharge
Screenings are compacted and pressed in the discharge zone to drastically reduce volume and moisture content. The final dewatered cake is discharged directly into a collection bin or transport system. The fully enclosed automated process contains odors and maintains hygienic operating conditions.

Product Parameters

Key Design & Performance Features

*Integrated All-in-One Design: Combines screening, conveyance, washing, and dewatering in a single, compact footprint, saving space and simplifying installation.
*Fine Screening Capability: Effectively removes particles down to 1-6mm screen apertures, protecting sensitive downstream equipment (e.g., pumps, MBR membranes).
*Low-Headloss Operation: The 35-degree installation and optimized hydraulics minimize upstream water level impact.
*Automatic, Self-Cleaning: Ensures uninterrupted operation with minimal operator intervention, reducing labor costs.
*Effective Dewatering: Produces drier solids cake, reducing waste volume and subsequent handling or disposal costs.

Applications

This unit is the perfect solution for projects demanding high-precision separation in compact installations. It offers versatile application across a wide range of industries:
*Municipal: Ideal as a primary or fine screening step in urban wastewater treatment facilities.
*Industrial: Delivers reliable pretreatment for effluents from food processing, pulp and paper, textile, and chemical operations.
*Specialized Projects: Well-suited for shallow channels and fine screen openings ranging from 1–6 mm, delivering high capture efficiency with minimal head loss.
