Product Description

The mechanical rotary fine bar screen stands as a critical first line of defense in modern wastewater treatment facilities, meticulously engineered to protect downstream pumps and delicate aeration systems from damaging debris. When you approach this machinery, the visual impact of its precision-welded stainless steel frame conveys immediate structural integrity, built to withstand the relentless corrosive nature of municipal sewage and industrial effluents. The continuous hum of the drive motor operates with a reassuring, low-decibel resonance, driving the heavy-duty rake chain system in a smooth, unyielding motion. As fluid rushes through the precisely spaced grid gaps, the interlocking rake teeth seamlessly lift suspended solids, rags, and plastics from the channel bed, carrying them upward with mechanical precision. This continuous screening process not only purifies the fluid stream but drastically reduces the manual labor traditionally required for debris removal. By integrating this screening equipment into your facility, you ensure uninterrupted flow dynamics, minimize costly maintenance downtime, and elevate the overall operational efficiency of your entire water purification plant.

• Convex Strip Tooth Surface: Engineered to resist deformation under heavy hydraulic loads, guaranteeing long-term dimensional stability even during peak flow surges.

• Self-Weight Discharge Mechanism: Utilizes gravity for dregs removal at the apex, reducing the need for complex secondary scraping mechanisms and lowering overall energy consumption.

• Enclosed Track Architecture: The chain and chain track form a closed state, actively preventing abrasive grit and screenings from infiltrating the moving parts, thereby avoiding jamming.

• Unattended Operation Capability: Designed for fully-automatic continuous or interval running, freeing up your facility personnel for more critical analytical and operational tasks.

Material & Craftsmanship

The physical endurance of screening equipment dictates its lifecycle value. We utilize premium-grade materials combined with advanced manufacturing techniques to deliver a product that thrives in severe environments. The tactile finish of the metalwork reflects a commitment to industrial excellence, ensuring your investment withstands the test of time.

• Corrosion-Resistant Core: The main machine frame is meticulously welded from SS304 stainless steel on a specialized assembly platform, ensuring absolute resistance to harsh chemical effluents.

• Precision-Stamped Rake Teeth: Formed through primary stamping with specialized molds and punching machines, the teeth offer exceptional tensile strength. You can select high-grade stainless steel or durable nylon based on your fluid characteristics.

• Nylon Isolation Pads: Strategically placed to maintain precise grid spacing, these pads absorb micro-vibrations and reduce metal-on-metal wear, extending the lifespan of the entire rake assembly.

• Rigorous Welding Standards: Adhering to strict general technical conditions for welding parts (JB/ZQ4000.3-86), every joint is inspected to guarantee flawless structural integrity against continuous hydraulic pressure.

Automation & Safety

Modern fluid management demands intelligent systems that protect themselves from unpredictable anomalies. This equipment integrates sophisticated electrical and mechanical safeguards to ensure your operations never suffer from catastrophic failures caused by unexpected debris loads or power fluctuations.

• Intelligent Auto-Control: The system runs autonomously, intelligently managing its screening cycles without requiring constant human supervision, drastically cutting down labor overhead.

• Thermal Overload Relay: Equipped with a highly sensitive hot relay device. If mechanical faults occur or debris causes a sudden spike in resistance, the system detects the overload instantly.

• Instantaneous Alarm System: Upon detecting a jam, the machinery automatically halts operations and triggers a loud, clear alarm, alerting your maintenance crew before any damage reaches the motor reduction box.

• IP55/F Motor Protection: The driving motor is encased with an IP55 protection level and Class F insulation, shielding the electrical core from splashing water, high humidity, and corrosive gases prevalent in pumping stations.

Filtration Efficiency & Anti-clogging

The primary mandate of any pretreatment screen is to capture waste without becoming a bottleneck itself. Through a masterful combination of kinetic design and fluid dynamics, this screen ensures maximum liquid passage while capturing the finest particulate matter, keeping your downstream processes pristine.

• Bottom-to-Top Screening: The continuous rotational plane captures sunken debris right from the channel floor, dragging it upwards to ensure no accumulation occurs at the base of your intake.

• Optimized Grid Gap: With a precise 5mm clearance, it effectively intercepts fine suspended solids that would otherwise foul downstream membrane bioreactors or aeration diffusers.

• High Flow Rate Capacity: Engineered to accommodate a flow rate of 0.9 m/s through the screen, maintaining high volumetric throughput without causing upstream backwater issues.

• Anti-Jamming Enclosure: By completely isolating the drive chain from the fluid pathway, the design guarantees that fibrous materials and rags cannot wrap around the sprockets, ensuring a perpetually smooth 2 m/min rotation.

Customization & Adaptability

No two water treatment facilities share the exact same architectural or hydrological profile. Recognizing this, we offer an adaptable engineering approach, allowing this screening technology to integrate flawlessly into your specific site requirements, whether it is a municipal plant or an industrial drainage system.

• Tailored Channel Dimensions: We custom-build the frame to match your specific infrastructure, accommodating standard channel widths like 800mm and depths of 1500mm, or modifying them based on your blueprints.

• Adjustable Installation Angles: Typically set at an optimal 75 degrees, the incline can be modified to suit the specific velocity and depth of your incoming fluid stream.

• Variable Discharge Heights: While the standard outlet height is organized at 750mm, we can engineer the discharge point to align perfectly with your secondary conveyors or slag storing devices.

• Component Flexibility: From the specific grade of stainless steel to the brand of the driving motor, every critical component can be specified to meet your internal procurement standards.

FAQ

To assist your procurement and engineering teams in their evaluation process, we have compiled answers to the most critical technical questions regarding our screening equipment.

• Q1: How do I determine the correct model and channel dimensions for my facility?
  A: The model selection must refer to your specific technical parameters and process requirements. You need to evaluate the average velocity of the flow across the gate, the water flowing area, and the volume of solid slag. Our engineering team is available to help calculate the optimal channel width, depth, and theoretical water flow to match your exact site conditions.

• Q2: What happens if the rake teeth encounter an immovable object in the wastewater stream?
  A: The equipment is designed with a highly sensitive electrical overloading protection device utilizing a hot relay. If a severe jam occurs, the system will immediately detect the mechanical resistance, automatically stop the motor to prevent gear reduction box damage, and trigger an audible and visual alarm for your maintenance crew.

• Q3: Can the discharge height be modified to fit our existing conveyor system?
  A: Yes, this is a highly customized product. While the standard outlet height is organized at 750mm, we can engineer the frame to match the exact height required to seamlessly integrate with your separately purchased slag storing or conveying devices.

• Q4: What civil engineering preparations are required before installation?
  A: Installation requires specific embedded parts in your concrete channel. The pre-embedded plates must be accurately positioned according to the installation angle (typically 75°). We provide detailed installation size figure shapes and technical consultations to guide your civil engineering team through the pre-embedded plate structure requirements.

• Q5: What maintenance is required for the continuous operation of the rake chain system?
  A: Thanks to the enclosed chain and track design, maintenance is minimal as it prevents screenings from falling into the track. Routine maintenance involves periodic inspection of the nylon isolation pads, checking the tension of the transmission device, and ensuring the motor reduction box is adequately lubricated. The system is built for 24-hour continuous or interval running with minimal intervention.
