Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a rotary tooth rake grille dirt remover. Background Art

[0002] The rotary tooth rake screen cleaner is a device used for sewage treatment, designed to remove solid impurities and suspended matter in sewage. It is one of the important equipment in sewage treatment projects and is widely used in urban sewage treatment plants, industrial wastewater treatment plants, rural domestic sewage treatment and other fields. The rotary tooth rake screen cleaner adopts the principle of physical filtration. The solid particles in the wastewater entering the equipment are intercepted and removed by the high-speed rotating tooth rake. Its working principle is to introduce the incoming sewage into the screen box of the tooth rake screen cleaner through the water inlet pipe, and then intercept the impurities, solid particles, etc. in the sewage through the high-speed rotation of the tooth rake, and lift it to the sewage outlet for discharge.

[0003] At present, during the use of a rotary tooth rake screen cleaner, although impurities and garbage in sewage can be intercepted and salvaged, the water flow will flow to the position of the cleaner during use. When there is a lot of garbage and impurities accumulated, it will move to the bottom of the cleaner, making it impossible to salvage the garbage and impurities under the cleaner, resulting in incomplete treatment. Therefore, a rotary tooth rake screen cleaner is proposed. Utility Model Content
