System for treatment of wastewater originated from a water consuming device

摘要

The wastewater treatment system comprises a pipe (2) for discharging the wastewater by gravity flow, and a device (7) for injecting a quantity of a liquid in the waste water for chemical or biological treatment, at each flow of wastewater, which comprises a tubular section (8) for connecting a source of treatment product to the discharge pipe and a movable valve unit between an opening and closing position of a passage of flow of treatment product in the pipeline and controlled at the opening by a discharge of waste water. The injection device is mounted in the evacuation pipe. The wastewater treatment system comprises a pipe (2) for discharging the wastewater by gravity flow, and a device (7) for injecting a quantity of a liquid in the waste water for chemical or biological treatment, at each flow of wastewater, which comprises a tubular section (8) for connecting a source of treatment product to the discharge pipe and a movable valve unit between an opening and closing position of a passage of flow of treatment product in the pipeline and controlled at the opening by a discharge of waste water. The injection device is mounted in the evacuation pipe, and comprises a mechanism for actuating the valve unit, which comprises a hinge mounted in the discharge pipe movable by the wastewater flow between a closing position of the valve unit and an opening position of the valve unit. The valve actuating mechanism is associated with the hinge so that the opening of the hinge causes the opening of the valve. The valve is associated with a spring of the valve in its closing position with a transmission mechanism. A body is fixed to the valve mechanism by shifting the valve. The transmission mechanism comprises an element connected to one end of the hinge, and comprises a unit for shifting the body against the spring associated with the valve. The transmission element is present in form of a lever, which is pivotally mounted in the connecting section, above the body, and further comprises a supporting ramp under the internal organ at a location of the face, which is opposite to the face on which the spring works.
