Description

Technical Field

[0001] The utility model relates to the technical field of grille dirt removers, in particular to a rotary chain type grille. Background Art

[0002] The screen cleaner is a kind of cleaning equipment that uses mechanical methods to clean the screen residue intercepted by the screen out of the water surface. Among them, the rotary screen cleaner is a special water treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid. It is widely used in urban sewage treatment, tap water industry, and power plant water inlet. It can also be used as a pre-screening equipment in the wastewater treatment process of textile, food processing, papermaking, leather and other industries.

[0003] The rotary screen dirt remover includes a frame, two sets of chain drive mechanisms respectively installed on both sides of the frame, a drive mechanism that drives the two sets of chain drive mechanisms at the same time, a screen fixedly installed at the lower end of the frame, and a tooth rake fixedly installed on the chain drive mechanism. The screen is facing the water inlet of the water treatment tank. The tooth rake rotates with the chain drive mechanism. When the tooth rake runs to the water-facing surface of the bottom of the grid bars, the rake teeth are inserted into the gaps between the grid bars, and the debris trapped on the grid bars is picked up from the bottom to the top. When it runs to the upper end, the debris falls from the slag discharge port by its own weight.

[0004] However, the tooth rakes and bars of the existing rotary screen dirt remover are usually composed of a plane, with a small filtering area and poor filtering effect. In addition, when the debris passes through the bars and reaches the upper end, it falls from the slag discharge port by its own weight and cannot be cleaned with the help of external force. It is easy for debris to remain unfallen, reducing the dirt removal effect. Therefore, a rotary chain screen is proposed. Utility Model Content
