Automatic, Compact, Durable, Guaranteed

The Automatic Bar Screen QLHP 220V for sewage plants provides automated, high-efficiency debris removal with multi-toothed rotary rakes, overload protection and variable-speed drive to protect downstream equipment. Its compact, reliable construction and easy maintenance translate to less downtime, while standard export carton packaging and 3–20 day delivery ensure safe, fast deployment. Backed by a one-year warranty, this Bar Screen integrates simply into treatment lines and pumping stations for continuous, worry-free operation.

Automatic 220V Reliable Screening

The QLHP Automatic Bar Screen 220V combines a rotary multi‑toothed rake with a middle‑mounted bar and chain traction driven by a variable‑speed motor and protected by overload devices, forming a compact, durable screening structure with automated control. As a primary screening unit for sewage plants, waterworks and pumping stations, the Bar Screen continuously intercepts and lifts debris through fixed‑grid gaps, then flips and discharges solids into conveyors or bins to protect downstream equipment and ensure uninterrupted operation. With configurable channel depths, grid spacings and installation angles, selectable body materials and an included control box, this unit delivers high cleaning efficiency, simplified maintenance, reduced downtime and is supported by a 1yr warranty.

Automatic Efficient Sewage Screening

The QLHP Automatic Bar Screen (220V) for sewage plants and pumping stations uses a rotary toothed rake and traction chain to intercept and lift debris, protecting downstream equipment and ensuring continuous operation. Its middle-mounted bars, multi-toothed harrow and overload-protection deliver high cleaning efficiency, reliable automated control and easy maintenance while automatically discharging captured solids. Available in multiple channel widths and depths with motor power options roughly 0.75–3 kW and customizable materials, the unit is supplied with a one-year warranty.

Efficient Reliable Durable Low-maintenance

Designed and manufactured to QLHP quality standards, the Automatic Bar Screen QLHP 220V for sewage plants reflects decades of wastewater engineering expertise and is backed by a one-year warranty. The Bar Screen uses an automated rake and corrosion-resistant bars to continuously remove rags, leaves and solids, minimizing manual cleaning and ensuring stable flow in municipal and industrial wastewater systems. Key features such as a compact footprint, energy-efficient 220V motor, adjustable screening gap, self-cleaning cycle and easy installation/maintenance deliver higher throughput, reduced downtime and lower lifecycle costs.

Material introduction

The QLHP Bar Screen features a corrosion-resistant stainless steel main frame and bar rack (commonly SS304 or SS316) to withstand continuous exposure to sewage and extend service life. High-strength, heat-treated alloy chains, sprockets and multi-toothed rakes offer wear resistance for reliable debris removal, while gate edges and slag boards use coated steel or rubber sealing to reduce abrasion and leakage. Materials and surface treatments can be customized on order (alternative steel grades or protective coatings) to match site chemistry and maintenance requirements.

FAQ

What is the Automatic Bar Screen QLHP 220V designed to do and where is it typically used?

The QLHP automatic bar screen is designed to remove coarse solids (rags, plastics, sticks, leaves, etc.) from raw sewage and wastewater flows before they reach pumps, grit chambers, or treatment basins. Typical application scenarios include municipal wastewater treatment plant inlets, pump/lift stations, industrial pre-treatment, stormwater screening, and combined sewer overflow control.

What electrical supply and site requirements does the unit need?

The product is built for a 220V AC supply (confirm single- or three-phase and frequency with the manufacturer or nameplate). The installation area should provide a stable power source with proper protection (circuit breakers, overload protection, and grounding) and conform to local electrical codes. Also ensure the channel geometry and flow depth are compatible with the unit’s design limits—check the datasheet or supplier for exact minimum/maximum depth and flow capacity.

How is the bar screen installed and commissioned on a typical wastewater channel?

Installation normally requires mounting the screen at the channel entrance or inline channel support, aligning it vertically/horizontally per the manufacturer drawing, anchoring to the structure, connecting the 220V power and control wiring, and setting sensor/limit switch positions. Commissioning includes checking rake travel, adjusting cleaning intervals and sensitivity, testing automatic/manual modes, and verifying safe access for maintenance. Professional installation or factory supervision is recommended for best results.

How does the automatic operation work and what user controls are available?

The QLHP unit typically operates automatically using a programmable cleaning cycle or level/flow sensors that trigger rake movement to remove accumulated solids. Common user controls include start/stop, automatic/manual modes, adjustable cycle timing, and alarm outputs (e.g., high-head loss or jam). A manual override allows safe hand or local control for maintenance. Exact control features vary by model—refer to the control panel manual.

What routine maintenance is required and what does the 1yr warranty cover?

Routine maintenance includes visual inspections of the rake, bars, chain/guideways, bearings and motor; lubrication of moving parts as recommended; checking electrical connections and limit switches; and replacing worn teeth or seals. Frequency depends on loading but weekly to monthly checks are common in heavy use. The 1yr warranty generally covers manufacturing defects in materials and workmanship; wear parts (teeth, chains, screens, seals) and damage from improper installation, misuse, or lack of maintenance are typically excluded. Keep maintenance records and contact the supplier for warranty service guidance.

What common problems should operators watch for and what safety/disposal practices are recommended?

Watch for excessive vibration or noise, repeated motor trips, incomplete rake travel, persistent head loss, or material bypassing the screen—these can indicate blockage, worn components, or improper setting. For safety, always isolate power and follow lockout-tagout, use appropriate PPE (gloves, eye protection), and do not enter confined spaces during operation. Screened solids should be handled per local regulations: dewatered, bagged, or transported for landfill/composting depending on content and contamination. Contact technical support for persistent faults or if uncertain about corrective actions.
