As a premier manufacturer and supplier of advanced fluid clarification systems, we present the Inclined Rotary Drum Screening Machine for Sewage Preliminary Treatment. Engineered for high-precision particle interception, this equipment seamlessly integrates into diverse wastewater channels to protect downstream infrastructure.
Consolidates debris interception, washing, lifting, and dewatering into one unified system.
Optimized for shallow channels featuring a precise 35-degree installation angle.
Consistently achieves a robust separation efficiency exceeding 97%.
Highly adaptable for municipal, food processing, and paper industry facilities.
The inclined rotary drum screening machine stands as a cornerstone in modern wastewater preliminary treatment, engineered to handle the rigorous demands of continuous fluid purification. When raw sewage flows into the drum port, the carefully calibrated grid immediately intercepts suspended matters, short fibers, and floating scum. Operating with a quiet, steady hum, the rotating drum gently lifts the captured debris. This slow, deliberate rotation ensures that gravel and hard objects pass through without causing abrasive damage to the core components, preserving the structural integrity of the entire system.
As the drum turns, a precise combination of heavy-duty nylon brushes and a pressurized water spray system meticulously cleans the grid surface. This dual-action cleaning mechanism prevents the accumulation of sticky organic matter and eliminates the risk of mesh blinding. The intercepted dregs are then smoothly conveyed upwards through a robust spiral lifting mechanism. During this ascent, gravity naturally draws excess water back into the channel, while the upper pressing zone aggressively compacts the waste. The resulting dewatered slag is discharged directly into transport containers, leaving behind a clear, odor-free operational environment. This fully enclosed, low-noise operation transforms heavily polluted intake water into a manageable, streamlined flow ready for secondary treatment stages.

Achieving optimal fluid clarification requires equipment that balances aggressive filtration with seamless operational flow. This screening machine is designed to tackle the most challenging intake conditions, ensuring downstream processes are fully protected from debris overload. By integrating multiple treatment phases into a single footprint, it redefines facility layout efficiency.
Self-Sustaining Cleaning Mechanism: The internal grid features a continuous self-cleaning action driven by wear-resistant nylon brushes, eliminating manual scraping and preventing flow bottlenecks.
Odor-Sealed Architecture: A fully enclosed structural design captures and contains volatile gases, maintaining a clean, breathable atmosphere for facility operators.
Gravity-Assisted Dewatering: The shaft screw conveying presser utilizes natural gravitational forces during the lifting phase to drain excess liquid, significantly reducing the weight and volume of the final discharged slag.
Automated Flush Control: The integrated grid frame flushing system is precisely regulated by a highly responsive solenoid valve, optimizing water usage while maintaining peak mesh permeability.
Our engineering philosophy centers on maximizing facility output while minimizing interventions. The following dimensions illustrate how this equipment elevates preliminary treatment standards across the board.

Navigating the technical specifications of preliminary wastewater treatment can be complex. Below are detailed answers to the most common operational and integration questions regarding our screening technology.
How does the equipment handle unexpected hard objects like gravel or metal?
The drum operates at a deliberately slow rotational speed. This controlled pacing allows heavy, abrasive objects like gravel to pass through or be gently lifted without causing impact damage to the stainless steel grid or the internal screw conveyor.
What makes the underwater bearing maintenance-free?
We utilize a premium copper alloy sliding bearing specifically engineered for submerged environments. It possesses inherent self-lubricating properties, meaning it requires no external oiling, thereby eliminating underwater maintenance tasks and preventing water contamination.
Can this machine be installed in existing shallow channels?
Yes, the system is explicitly designed for high adaptability. With a standard 35-degree installation angle, it easily integrates into channels with a width of 700mm and accommodates shallow water depths, making it ideal for retrofitting older facilities.
How is the odor control managed during the pressing and discharging phase?
The entire conveying and pressing pipe, along with the drum assembly, features a fully sealed structure. This robust containment prevents volatile organic compounds and foul odors from escaping into the surrounding plant environment.
What is the typical lifespan of the nylon cleaning brushes, and are they easy to replace?
Under standard municipal wastewater conditions, the heavy-duty nylon brushes offer exceptional longevity. When replacement is eventually required, the accessible drum design allows maintenance personnel to swap them out quickly during routine scheduled downtime without dismantling the entire unit.
Does the equipment require a continuous fresh water supply for the flushing system?
The flushing system is highly efficient, utilizing a solenoid valve to control the flow. It only activates when necessary to maintain grid permeability, significantly reducing overall water consumption while ensuring a separation efficiency of over 97%.
