Mechanical Bar Screen

The Mechanical Bar Screen is solid-liquid separation equipment that integrates an adjustable rake gap, an efficient transmission system, and an intelligent drive unit. It realizes wastewater pretreatment through physical interception and automatic cleaning technology and is widely used in municipal sewage, industrial wastewater, and circulating water purification.

High-efficiency and low-consumption design
The mechanical bar screen uses a high-torque, low-speed motor with an automatic tensioning chain to significantly reduce energy loss. Compared with traditional equipment, energy-saving efficiency is increased by 25%, and the energy consumption for treating 10,000 tons of wastewater is only 0.8kW·h.

Precise separation ability
The adjustable rake gap and 75°-85° installation angle of the mechanical bar screen optimize the water flow trajectory, realize efficient interception of suspended matter, and make the screen residue removal rate ≥95%.

Intelligent protection mechanism
The mechanical bar screen integrates mechanical shear pins and current overload protection and automatically shuts down when encountering hard objects to avoid equipment damage. This protection system reduces the failure rate by 40%, effectively reduces the economic losses caused by unplanned shutdowns, and is particularly suitable for treating wastewater containing complex impurities.

Convenient maintenance
The mechanical bar screen has a modular design, allowing quick assembly/disassembly. Its self-cleaning function enables annual maintenance intervals, while the automatic sprocket tensioning reduces manual adjustments. Key components like 304 stainless steel rakes last over ten years, significantly cutting maintenance frequency and costs.

The mechanical bar screen consists of nylon or stainless steel rakes evenly spaced along a rake shaft, forming a closed rake chain. Installed at an inclined angle within a channel, the system operates as the transmission drives the sprocket to rotate at a constant speed, propelling the entire rake chain in a continuous cyclical motion from top to bottom. As the rakes traverse the channel, they intercept and lift solid waste from the water surface, while the fluid passes freely through the inter-rake gaps. Upon reaching the upper terminal and reversing direction, the debris-laden rakes release their collected material under gravity, completing a seamless and uninterrupted separation process.
