Product introduction

FHG anti-dredge grille is a large and medium-sized water supply and drainage project in the water intake of the front of the sewage control equipment, generally used for medium and coarse grille. Widely used in municipal sewage water works, hydropower stations, sluices, and other water conservancy facilities in the larger floating objects interception and removal (such as branches, weeds, wood scraps, plastic products domestic waste, etc.).



  • The multi-set of harrow teeth with equal distance distribution can be used to automatically and continuously prevent a large amount of garbage from clogging the grid.
  • Dregs thoroughly, high separation efficiency. 
  • Machine factory, easy to install.



FHG anti-fishing grille is composed of a transmission system, frame, rake teeth, traction chain, underwater guide wheel, attached grid, main grid,    slag baffle, and so on. The transmission system drives the rake tooth rod to rotate up and down along the guide rail through the traction chain. The rake goes down from the rear of the grid strip and runs to the front of the grid strip through the underwater guide wheel at the bottom. The floating objects stopped by the grid strip are pulled up along the baffle plate to the slag discharge port from the bottom up and unloaded onto the conveyor belt or into the garbage truck.

Mechanical Screen industry knowledge

As the core cleaning equipment in modern sewage treatment facilities, the innovative design and high-efficiency performance of the Dredge Bar Screen provide important guarantees for urban water resource treatment. This type of equipment can not only effectively intercept large floating objects in the water body, but also build the first line of defense for the stable operation of subsequent sewage treatment.

In municipal sewage treatment plants, hydropower stations and other scenarios, Dredge Bar Screens are usually installed at the front end of the water intake, and the rake teeth made of high-strength stainless steel or engineering plastics form a dynamic filtration barrier. Its core transmission system uses a gear reduction motor to drive the active sprocket to drive the annular traction chain to reciprocate along the guide rail. When the water flows through, floating objects such as branches and plastic products are intercepted in the area in front of the grille. At this time, the traction chain drives the rake teeth to move from bottom to top, and with the assistance of the slag baffle, the dirt is lifted to the discharge port to complete the automatic slag discharge process.

The convenience of installation and maintenance is reflected in its prefabricated component design. The main components of the equipment have been pre-assembled when it leaves the factory, and it can be put into use on site with only a simple debugging of the control system.
With the development of smart water services, this innovative equipment that integrates mechanical engineering and environmental science is driving the water treatment industry towards a more efficient and intelligent direction.
