Overview
The trash rake coarse bar screen is a mechanical filtering device, usually installed at the water inlet, used as the primary stage of wastewater treatment, intercepting and removing large floating objects such as rags, plastics and branches, protecting downstream equipment from damage by large floating objects. The device consists of a series of vertically arranged steel bars with spacing between 1 and 3 inches. These bars are regularly cleared of accumulated debris by motor-driven rake teeth to prevent overflow caused by rising water levels.

Features
Strong Corrosion Resistance
The trash rake coarse bar screen is made of 304/316 stainless steel, which has extremely strong corrosion resistance and can operate for a long time in industrial wastewater containing chloride concentrations up to 500 mg/L without significant corrosion. However, under similar environments, the corrosion depth of traditional galvanized steel can reach more than 100 microns per year, and its lifespan usually does not exceed 5 years.
Anti-slip
Operators who need to step on slippery grating surfaces for routine maintenance or cleaning work are at risk of slipping. The surface of the trash rake coarse bar screen has been sandblasted to increase the friction coefficient to above 0.8 and increase the surface roughness. Even if it is tilted at 30 degrees and the surface is covered with 3 mm of oil, it can still effectively prevent slipping. Treating steel improves anti-skid performance by 20%, improving operator safety.
Efficient Automatic Cleaning
The trash rake coarse bar screen is equipped with an automatic rake tooth cleaning system. Its programmable logic controller (PLC) can accurately set the cleaning cycle to ensure efficient operation and avoid system failure due to accumulation of floating objects. The maximum cleaning volume per hour can reach 500 cubic meters, which is suitable for Large-scale water treatment project.
High Load Carrying Capacity
The thickness of trash rake coarse bar screen can reach 8-12 mm, and the maximum load-bearing capacity can reach 2000 kg. This high-carrying-capacity design enables the equipment to operate stably under conditions of high flow (for example, 15,000 cubic meters per hour) and high floating density (for example, the floating density reaches 5 kilograms per cubic meter) without being affected by weight. Deformed or damaged due to accumulation of objects or impact.
