1 Under normal circumstances, the rotating drum mechanical grille automatically controls intermittent operation, but it can automatically run continuously for 24 hours when the water volume is large and the dirt is too much . 2 The rotating drum type mechanical grille is set in the sewage inlet channel to collect and remove particles and floating matter, and discharge the dirt to the screw conveyor for transportation. The moisture content of the grille slag is about 65% . 3 When the rotating drum type mechanical grille is running, the self-cleaning rotating drum runs in a circle to effectively intercept the grille slag in the sewage. The high-pressure washing device installed on the upper part of the rotating drum sprays the grid slag into the spiral conveying device located in the center of the grid basket, and is transported out of the grid cylinder. At the same time, the grid slag is further dehydrated until it is discharged to the grid. Exit. The transmission and pressing of the grid slag are completed in a fully sealed state, which effectively reduces the odor and meets the environmental requirements. 4 The drum-type mechanical grille is designed to withstand a water level difference greater than 1.0m , especially in emergency situations to ensure no deformation and running performance.
