As a leading manufacturer and supplier of advanced water purification equipment, we present the Automatic Multi Rake Fine Bar Screen. Engineered for municipal and industrial wastewater facilities, this robust screening solution effectively intercepts and removes solid debris.
Fully automatic operation for continuous, unattended debris removal.
Customizable channel depth and precision grid gaps ranging from 1 to 15mm.
Durable SS304 stainless steel construction with reliable overload protection.
Ideal for drainage pumping stations, urban effluent systems, and industrial plants.
The Automatic Multi Rake Fine Bar Screen stands as a highly recognized pretreatment filtration system designed to safeguard your downstream wastewater treatment infrastructure. When approaching the installation site, the quiet, rhythmic hum of the precision-engineered driving mechanism replacing the chaotic splashing of clogged channels is immediately noticeable. This mechanical rotary screen operates with a smooth, continuous upward motion, effectively capturing and elevating suspended solids, rags, and plastics from the effluent stream. The heavy-duty stainless steel frame feels solid to the touch, reflecting a meticulous welding process built to withstand the harshest corrosive environments.
By automatically discharging the accumulated dregs through the self-weight of the screenings and a specialized turning brush removal device, it drastically reduces the manual labor traditionally required for channel maintenance. Your facility benefits from uninterrupted flow rates, protected water pumps, and a significant reduction in subsequent workload. The sleek, metallic finish of the SS304 structure not only looks professional but ensures a long-lasting, rust-resistant lifespan even when exposed to raw municipal sewage or volatile industrial wastewater. Every component is engineered to deliver a seamless, flexible, and highly reliable operation that improves the overall efficiency of your plant.

Important Engineering Notes | |
|---|---|
Note 1 | Theoretical water flow (exclude sediment etc.) = average velocity of the flow across the gate × water flowing area × the effective rate of water flowing area. |
Note 2 | The designed water flow rate V= 1m/s corresponding to the water level difference is approximately as ▵H=200MM. |
Note 3 | Water flowing area = Channel width B × (Water level H1- ▵H) / sinα. |
Note 5 | The actual water flow should be based on the gate slag and water etc. Usually, it is generally estimated at 0.5 times the theoretical value. |
Ordering Instruction 1 | The model selection must refer to the technical parameters and process requirements. The model and the slag outlet height must be indicated. Otherwise, the height of slag outlet will be organized as 750mm. |
Ordering Instruction 2 | If the material and motor brand are not noted, we will use our domestic motor, and the material will be SS304. |
Ordering Instruction 3 | The preembedded plate, slag storing device, conveying device are all needed to be purchased separately. The installation structure of the preembedded plate needs to be asked from our technician. |
Our mechanical fine bar screen is engineered with a strict focus on autonomous reliability and structural integrity, ensuring your plant operates at peak efficiency without requiring constant human supervision. The design prioritizes continuous flow and equipment protection.
Fully-Automatic Control: The system operates flawlessly unattended. In the rare event of a jam, the intelligent sensors immediately trigger an alarm and automatically stop the machine to prevent mechanical damage.
Sensitive Overloading Protection: Utilizing an advanced hot relay electrical overloading protection device, the motor and reduction box are safeguarded against sudden torque spikes or mechanical faults. Actions of this device are sensitive and highly reliable.
Integrated Secure Frame: The main machine frame is an integrated type, welded to a special assembly platform according to JB/ZQ4000.3-86 conditions, ensuring the structure is secure and reasonable.
Deformation-Resistant Teeth: The rake teeth are stamped with convex strips, providing exceptional structural strength that ensures it is not easy for deformation by heavy strength.
Closed Chain Tracking: The drive chain and chain track form a closed state, which effectively prevents screenings from falling into the track and completely avoids jamming.
The longevity of wastewater equipment heavily relies on its material composition and surface treatment. We utilize premium-grade materials combined with advanced anti-corrosion techniques to deliver a filtration product that outlasts standard alternatives in demanding environments.
The core components, including the main supporting frame, rake teeth, and roller chains, are constructed from high-quality SS304 or 316L stainless steel.
Surfaces are treated with rigorous acid pickling and passivation processes to create an impenetrable barrier against highly corrosive sewage environments.
The rake teeth feature an innovative convex strip design formed through primary stamping, significantly enhancing tensile strength.
Nylon is utilized as an isolation pad to ensure precise spacing between teeth, preventing metal-on-metal wear and extending the operational lifespan.
Maximizing throughput while maintaining strict filtration standards is critical for any intake facility. This multi-rake system is designed to handle high-volume challenges effortlessly, ensuring downstream pumps remain entirely free from obstructions.
Employs a multi-rake continuous rotary structure that intercepts and clears debris doing screening work from bottom to top.
Delivers an exceptionally high slag discharge capacity while maintaining a remarkably low headloss across the channel.
Easily manages high concentrations of suspended solids, sudden large flow surges, and sticky, fibrous waste.
The solid suspended matter intercepted on the toothed harrow is picked up to the discharge port and cleared away thoroughly by a turning brush.
Modern wastewater management demands intelligent systems that protect themselves and alert operators only when absolutely necessary. Our automated control suite provides peace of mind and operational security for your entire facility.
Features a fully automated, unmanned control system tailored for 24 hours/day continuous run or interval run based on site requirements.
Equipped with highly sensitive dual mechanical and electrical overload protection, utilizing a rapid-response hot relay system.
Incorporates an auto-reverse or alarm-and-stop function upon encountering insurmountable resistance.
This device acts accurately to effectively prevent any damage caused by over-loading to the motor reduction box.

The system is equipped with a highly sensitive mechanical and electrical dual-protection mechanism. If rigid debris causes a sudden spike in resistance, the hot relay electrical overloading protection instantly halts the motor and triggers an alarm, preventing any structural deformation or damage to the motor reduction box.
Yes. The equipment features an easy-to-retrofit structural design. We customize the machine net width and channel depth to precisely match your existing infrastructure. The scientifically optimized 75° installation angle also ensures it fits seamlessly with minimal overhead clearance requirements.
One of the core advantages of this design is that it requires virtually zero underwater maintenance. There are no bottom bearings submerged in the effluent. The closed chain track prevents debris accumulation, meaning routine maintenance is confined to the easily accessible above-ground drive and brush mechanisms.
The grid gap (ranging from 1mm to 15mm) should be selected based on the nature of the suspended solids and the requirements of your downstream pumps. For fine municipal pretreatment, 3mm to 6mm is typical, while industrial applications with larger debris might utilize 10mm to 15mm. Our engineers will assist in calculating the ideal gap based on your flow rate and solid composition.
Absolutely. The structural framework is designed to accommodate fully enclosed, removable covers specifically engineered for odor control. These covers seal the extraction and discharge zones, preventing noxious gases from escaping into the facility and ensuring compliance with strict environmental and worker safety regulations.
