Tooth Rake Bar Screen

As an important treatment equipment in the sewage treatment system, the tooth rake bar screen plays an irreplaceable role in municipal engineering and industrial wastewater treatment with its efficient solid-liquid separation ability and reliable structural design. The equipment realizes the removal of solid impurities in sewage through a unique dynamic interception mechanism of the rake chain, which not only protects the safe operation of key equipment such as water pumps, but also lays the foundation for the efficient operation of subsequent treatment.

From a structural point of view, the core component of the tooth rake bar screen is composed of rake teeth made of high-strength nylon or stainless steel. These specially designed wedge-shaped rake teeth are evenly assembled on the chain shaft at a specific spacing to form a closed ring rake chain structure. Driven by the drive device, the chain moves from bottom to top along the track through the underwater sprocket reversal. When the sewage flows through the grille surface, the rake teeth are accurately inserted into the gap between the bars to intercept and lift the suspended impurities such as leaves, fibers, and plastics to the discharge port. Under the synergistic effect of the curved rail and the cleaning device at the top of the equipment, relative displacement occurs between the rake teeth, and the dual mechanisms of gravity self-cleaning and reverse flushing are used to ensure that the intercepted materials can effectively detach from the rake teeth and be centrally processed by the screw conveyor or pressing system.

As an important part of the water treatment process, the technological evolution of the tooth rake bar screen has always kept pace with environmental protection standards. This product will further reduce the carbon footprint of the equipment and promote the sewage treatment industry to a greener and smarter direction.
