Tooth Rake Bar Screen

The harrow teeth made of nylon or stainless steel are assembled on the chain shaft in a certain arrangement order to form a closed ring tooth harrow chain. The whole harrow tooth chain is driven by the drive sprocket to do the continuous circulating movement from bottom to bottom, and the suspended solids trapped on the harrow teeth are transported from the sewage to the ground or above the platform, and the materials are removed during the rotation and engagement of the harrow teeth. The purpose of this is to protect the pump and reduce the processing load of the subsequent process.

Note：

1. Theoretical water flow (not counting slag and other factors)= designed average gate velocity X water area X water surface efficient;

2. Water crossing area = channel width Bx(front water level H1-AH)/sina;

3. The power in the table corresponds to the moving speed of rake teeth 2m/min;

4 . The actual flow rate should be included in the grid slag, water, and other factors, generally estimated at 0.5 times the theoretical value.
