Product Usage
This machine is used in municipal sewage and industrial wastewater treatment projects to remove floating objects in the water. It integrates four functions of sewage blocking, slag removal, screw lifting, and pressing and dehydration. It is a new type of high-efficiency grille decontamination machine.
Working principle and structure
It is mainly composed of electric drive device, grid screen body, washing system device, collecting hopper, screw body, material conveying press cylinder, cleaning cylinder, backwashing device, front and rear legs and other components. It can be installed in the box or directly in the ditch. When the sewage enters from the front of the basket, the filter residue is intercepted by the screen; at the same time, it is covered on the screen to form a filter layer, which has an additional fine filtering effect on the filter residue. . Due to the special shape of the screen and the reasonable arrangement, it can ensure that the filter residue can only be trapped on the inner surface of the screen without clogging in the screen gap. As the filter residue is gradually retained and the filter area is gradually reduced, the water level in front of the grid increases. When the water level in front of the grid reaches the set value, a signal is sent by the liquid level gauge or time relay, and the motor starts to start, and drives the rotating arm and the transmission screw at the same time. At this time, the solenoid valve in the flushing system is automatically opened, and the tap water is flushed by the flushing pipe to flush the screen, and the brush will first brush the retained material into the material hopper in the center of the screen body (that is, flushing while brushing); The retentate that falls into the material hopper after washing is transported and lifted by the transmission screw, and at the same time is pressed and dehydrated, and finally falls into the material box or conveyor from the discharge port for outbound processing. The solid content of the pressed and dehydrated filter residue can reach 40%. %DS.
