Compact Build, Reliable Screening

The QLHP Manual/Automatic Rotary Bar Screen (220V, 1‑Year Warranty) delivers high‑efficiency debris removal and uninterrupted protection for pumps and downstream processes with its multi‑toothed rotary harrow, overload protection and optional automated control. Its compact rotary frame and middle‑mounted bar arrangement prevent chain blockages, simplify maintenance and provide consistent screening across varied channel depths and angles. Packaged in standard export cartons, shipped within 3–20 days and backed by a one‑year warranty, it ensures fast delivery, easy installation and reliable long‑term operation.

Here are five four-word subtitle options:

The QLHP Manual/Automatic Rotary Bar Screen (220V, 1-Year Warranty) combines a rotary multi-toothed rake driven by a variable-speed motor and reducer with a middle-mounted bar and draught chain to intercept, lift and automatically discharge debris, ensuring continuous decontamination and protection of downstream equipment. Its compact, robust frame, spindle and gate design, along with overload-protection devices and adjustable bar spacing, deliver high cleaning efficiency, reduce chain blockages and simplify maintenance while supporting manual or automated control. Available in multiple channel depths, widths and tooth intervals with selectable materials and outlet heights, the Bar Screen provides reliable, high-throughput screening that is easy to integrate into municipal and industrial water treatment systems.

220V Rotary Screen 1-Year

The QLHP Manual/Automatic Rotary Bar Screen is a compact, reliable rotary toothed-harrow bar rack cleaner used in sewage plants, water supply facilities and pumping stations to capture floating debris and protect downstream processes. With the bar mounted centrally on the traction chain, a variable-speed motor driving multi-toothed rakes and overload protection delivers high-efficiency, continuous cleaning and automated control while lifted solids are conveyed and dumped automatically. Available in multiple channel widths and depths with motor power options up to 3 kW, the unit supports 220V operation, customizable materials and control cabinets, and is backed by a 1-year warranty.

Efficient Durable Low-Maintenance Screening

The QLHP Manual/Automatic Rotary Bar Screen 220V 1-Year Warranty reflects decades of wastewater equipment expertise, featuring precision-engineered stainless-steel components and a compact, service-friendly design for continuous, reliable screening. This Bar Screen operates in both manual and automatic modes with an energy-efficient 220V motor, adjustable bar spacing and a self-cleaning rotary mechanism that efficiently removes rags, leaves and solids while minimizing blockages. Key advantages include corrosion resistance, easy installation and maintenance, low power consumption, high throughput, and a one-year warranty backed by responsive after-sales support.

Material introduction

The QLHP Bar Screen is constructed primarily from corrosion-resistant stainless steel (typically SS304, with SS316 available) for the bars and main frame to endure continuous exposure to wastewater. Rake teeth and traction chains are made from hardened alloy or galvanized steel for high wear resistance and reliable overload protection, while guide plates and seals use abrasion-resistant polymers or rubber. Structural supports often use carbon steel with epoxy or powder coatings for added strength and cost-effectiveness, and material options can be customized to suit site-specific conditions.

FAQ

What is the QLHP Manual/Automatic Rotary Bar Screen and where is it typically used?

The QLHP Rotary Bar Screen is a mechanical screening device used to remove coarse solids from flowing water or wastewater. It operates in manual or automatic modes and is designed for a 220V power supply. Typical application scenarios include municipal sewage and wastewater treatment plant headworks, stormwater and combined sewer overflow screening, industrial wastewater pretreatment (food processing, pulp and paper, aquaculture, chemical plants), pumping station intakes, and any process where large debris must be intercepted to protect downstream equipment (pumps, grit chambers, membranes).

How do the manual and automatic modes work, and when should each be used?

In manual mode, the operator starts and stops the unit and can perform cyclic rake movements or clearing as needed — useful for commissioning, intermittent flow sites, or when staff want direct control. In automatic mode the screen works continuously or on demand using built-in control logic and sensors (e.g., timer, level float, photocell, or a programmable controller) to start cleaning cycles and stop when clear. Use automatic mode for unattended, continuous-flow applications (e.g., municipal lines) and manual mode for low-flow, infrequent-use, or during maintenance and inspection.

What site and electrical requirements are needed for installation?

The unit requires a stable mounting (concrete foundation or steel supports), correct alignment with the channel or trough, and sufficient access space for inspection and maintenance. Provide a dedicated 220V electrical supply as specified by the manufacturer (confirm single- or three-phase version with your supplier), with proper circuit protection, earthing/grounding, and an IP-rated control panel appropriate to the site. Ensure inlet and outlet clearances, safe lifting points for installation, and a drainage or washdown arrangement. Follow local electrical codes and the product manual for exact wiring and foundation drawings.

What routine maintenance and cleaning does the QLHP Rotary Bar Screen require?

Regular maintenance keeps the screen reliable: perform daily visual inspections for blockages, unusual noise, or raking issues; clear accumulated debris as needed. Weekly: check fasteners, drive belts or chains, and ensure the rake and bars are moving freely. Monthly: inspect bearings, lubrication points, and electrical connections; clean sensors and control enclosures. Replace wearing parts (rakes, bars, seals, bearings) when showing significant wear. Always isolate electrical power and lock out/tag out before performing maintenance. Keep recommended spare parts on hand (wear strips, seals, fuses, common fasteners).

What are common problems I might encounter and how can I troubleshoot them?

Common issues and quick checks: - Motor does not start: verify power supply (voltage, breaker), emergency stop not engaged, control mode set correctly, and wiring to motor terminal box. - Screen jams or heavy blockage: stop unit, visually inspect for large debris or rags, remove obstruction, check rake teeth and bar damage. - Abnormal vibration or noise: check alignment, loose fasteners, worn bearings or coupling, and secure foundation. - Poor screening (debris passes through): inspect bar spacing, bent bars, or damaged rakes; verify correct model for debris size. If faults persist, record error indicators, take photos, and contact technical support with serial number and purchase details.

What does the 1-year warranty cover and how do I request service?

The standard 1-year warranty covers defects in materials and workmanship under normal use for the first 12 months from the date of installation or delivery (check your contract for the exact start date). It typically excludes normal wear parts (rakes, bars, seals, bearings), damage from improper installation, misuse, corrosive chemical exposure not specified by the manufacturer, unauthorized modifications, or lack of routine maintenance. To request service: contact the supplier or authorized dealer with your purchase invoice, product serial number, installation date, and a clear description (photos if possible). Follow the supplier’s instructions for returns or on-site service. Keep records of installation and maintenance to support warranty claims.
