Internal Inlet Grille Wastewater Pretreatment Equipment Industrial Water Pretreatment

【Wastewater treatment pretreatment equipment】Technical parameters of internal inlet grille

The internal inflow grille cleaning machine is formed by a continuously rotating orifice plate driven by an electric motor placed in a fixed frame. The filtered sewage enters from the middle opening of the grille and flows out through the orifice plates on both sides for impurity filtration from the inside out. The filter orifice plates rotate simultaneously, and the impurities accumulated on the inner side of the orifice plate are lifted to the top slag discharge area by the lifting plate on the orifice plate, and are washed by flushing water into the slag collection tank, which is led out by the built-in spiral conveying device. There are mainly two types of materials for filter orifice plates, one is stainless steel orifice plate, and the other is engineering plastic. The internal inlet grille cleaning machine is shown in the figure.
