Rotary Drum Grating

Operating Principle
The rotating cleaning screen drum moves in a circular motion with a 35° inclination, completing 5 to 8 rotations per minute, with one-third of the drum submerged in water. Wastewater and floating debris enter the drum through the bottom, adhering to the inner wall of the drum and being removed from the water. As the drum rotates, impurities fall into the waste conveyance system due to gravity and are compressed through the conveyor system to the discharge point. Filtered wastewater flows out through the gaps in the drum.

Features and Applications
Standard格栅污物清除机 requires a helical conveyor and a sludge press. The OA drum-type格栅污物清除 machine integrates cleaning, conveying, and pressing, enhancing energy efficiency and reducing management costs.
The OA type drum格栅 cleaner effectively removes impurities due to its fixed mesh gap, overcoming the issue of moving gaps in traditional rake type gratings, achieving a cleaning efficiency of over 98%.
The ends of the net tube are secured by welding thick stainless steel rings with high concentricity to the net tube, ensuring the concentricity of the net tube during rotation.
The spiral rotation power of the conveying squeezing unit comes from the same reducer as the drum rotation. The conveying squeezing spiral is an axial spiral, with stainless steel blades, and the pitch decreases gradually from bottom to top, resulting in an increasing squeezing capacity.
