Abstract
An automatic flushing device for a screen filter of a biogas slurry drip irrigation system and a use thereof are provided. The automatic flushing device includes a feeding mechanism, a filter unit, a discharging mechanism and a control mechanism, where the filter unit is provided with a feeding end fixedly threaded to a discharging end of the feeding mechanism and a discharging end fixedly threaded to a feeding end of the discharging mechanism; and the control mechanism is clamped on a pipe of the feeding mechanism. The automatic flushing device enhances the cleaning strength and uniformity of ultrasonic waves to the filter screen. The ultrasonic vibration rod is nested inside the upper filter casing through the externally-threaded hollow cap and a threaded top portion of the upper filter casing, which greatly facilitates the cleaning, replacement and maintenance of the ultrasonic vibration rod.
