Screen Grid

Structure and Performance
    The screen grid machine can remove floating objects and fibrous materials without clogging or causing water backup during operation, ensuring thorough clearance of debris. It mainly consists of a drive device, frame, transmission sprocket, traction chain, screen plate, and electrical control cabinet. During operation, the screen plate is driven by the transmission chains on both sides, moving upward from the bottom to lift debris across the entire channel width. Upon reaching the top, the turning function of the sprocket automatically completes the debris discharge.
The screen grid step debris removal machine provides reliable cleaning results, with a structurally designed self-cleaning capability that prevents debris entanglement or jamming. There is no debris accumulation forming dead angles at the bottom of the grid. It is suitable for 24-hour continuous operation.

Drive Device
    The drive device of the screen grid machine is located at the upper part of the frame. Except for the transmission components, the rest are made of stainless steel. The drive device uses a shaft-mounted reducer, with spiral adjustment mechanisms on both sides of the frame for adjusting the tension of the transmission chains.
    The drive motor is suitable for a power supply of 380V/three-phase/50Hz, with a protection rating of IP55 and an insulation class of F. The motor's rated power is 10% higher than the maximum actual power consumption. It is equipped with an overload protection device.
    The design of the transmission shaft has sufficient strength and stiffness to withstand loads from both bending moments and torque.
