Corrosion and Wear Resistant Rotary Drum Fine Screen Automatic Screen Cleaning Energy Saving

Corrosion and Wear Resistant Rotary Drum Fine Screen Automatic Screen Cleaning Energy Saving

Brief Description

Designed for corrosive or highly abrasive environments, key components are made of corrosion- and wear-resistant materials to extend service life. Equipped with an automatic screen cleaning mechanism to prevent screen clogging and ensure long-term efficient operation. Suitable for wastewater treatment systems in industries such as electroplating, printing and dyeing, and papermaking, reducing the frequency of manual cleaning and improving overall automation.

Product Overview

Built to deliver efficiency and consistent reliability, our Rotary Drum Fine Screen offers a complete solids separation system for challenging wastewater environments. It stands out in removing fine suspended matter—scum, short fibers and particulates included—producing clean effluent and dense, dewatered screenings to optimize downstream processes.

Working Principle

This compact, smartly engineered system merges interception, cleaning, lifting, and dewatering into one self-contained unit, delivering a fully autonomous solid-liquid separation solution for wastewater treatment facilities.
1. Interception
The 35-degree angled drum rotates uniformly inside the channel, creating ideal flow conditions. Wastewater flows into the intake, and the precision fine screen intercepts coarse and fine solid particles alike.
2. Cleaning
Self-cleaning operates nonstop with drum rotation: wear-resistant nylon brushes dislodge surface solids, while high-pressure sprayers flush the screen clean, preserving filtration efficiency and prolonging service life.
3. Lifting & Conveyance
Separated screenings are channeled to the integrated internal screw conveyor, which lifts solids vertically out of the water flow smoothly and efficiently, with no material jamming.
4. Dewatering & Discharge
Solids are pressed and compacted to remove excess moisture, reducing disposal volume substantially. Dewatered cake is discharged automatically, and the hermetically sealed process contains foul odors for a clean working environment.

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

For projects that require accurate separation within limited installation space, this unit provides universal adaptability across various applications:
*Municipal: Used for primary or fine screening duties in urban wastewater treatment plants.
*Industrial: Highly effective for pre-treating effluent from food processing, pulp and paper, textile, and chemical industries.
*Specialized Projects: Ideal for low-depth channels and fine screening requirements (1–6 mm), ensuring high capture rates and negligible head loss.
