Coarse bar screen is a pre-treatment equipment for large and middle scale water supply and drainage works. It is widely used for municipal wastewater, waterworks, hydropower station and pump station to intercept and clean bigger floating objects (such as branches, weeds, woodchips, plastic wastes, household wastes and so on).
|Structure and working principle |
FHG Coarse Screen is made of rotational system, rack, traction chain, underwater guide wheel, attached grid, main grid and slag rataining plate. The rotational system drives the tooth harrows to turn up and down by traction chain. The tooth harrows get down at the back of the grid. Underwater guide wheel changes its direction to the front of the grid in the bottom. The floating objects intercepted by the grid will be seized to the slag discharged part from bottom to top, then they will be transported to the conveyor or garbage truck.
1-Using the isometric distribution toothed harrow to block the dirt automatically and continuously can avoid a large number of rubbish to block the screen.
2-Thoroughly in dregs seizing, high separation efficiency.
3-Complete machine, convenient installation.
