该设备由一种*的耙齿结构组装成回转格栅链，在电机驱动下，格栅链与水流方向成逆向回转运动。原水流经格栅时，各类固体杂质被截留在筛网上，在电机和减速器驱动下，耙齿链下行，呈张开趋势；当耙齿链达到渠底，在导向轮的作用下，耙齿链将栅渣耙入；当耙齿链运转到设备的上部时，所载杂质依靠自身重力从耙齿上剥落，而粘在耙齿上的杂质会被清扫器不断清除，并滑入容器或传输带，在完成排渣后，在导向轮作用下，耙齿链下行，进入下一个工作循环。
The equipment consists of a unique rake tooth structure assembled into rotary grill chain, motor drive,grill chain with the flow direction at the reverse rotation movement.When the original flow through the grille,all kinds of solid impurities were closure in the sieve, downstream of the motor and gear drive ,chain harrow teeth,was open trend;rake tooth chain to reach the channel bottom ,in the role of guide wheel tooth harrow,chain harrow into the gate slag;when the rake tooth chain running to the upper part of the equipment contained in impurities on their own gravity to peel off from the harrow teeth,impurities stick to the rake teeth will be cleaner continue to clear and slide container or conveyor belts. After the completion of the slag under the guide wheel rake tooth chain downstream,into the next work cycle.
