Description

TECHNICAL FIELD

[0002] Rotary cleaners are often used in sewage treatment. Rotary cleaners are usually arranged at the water inlet of a sewage tank in a sewage treatment plant, and are generally provided with grating devices (such as coarse grating, fine grating, and ultra-fine grating). The core function of the rotary cleaner is to intercept large floating objects (such as branches, waterweeds, household garbage, and plastic products) and suspended solids in the water flow, so as to prevent these sundries from entering the subsequent treatment process or core equipment, and to preliminarily clean the suspended solids in the sewage.
