The utility model provides a drainage pipeline inverted
siphon device capable of automatically dredging and discharging
sludge. The drainage pipeline inverted
siphon device comprises a water inlet well, a water outlet well, a water inlet well
sludge hopper, a water outlet well
sludge hopper, an inverted
siphon pipe, a water inlet well lifting device, a water outlet well lifting device, an
air compression device, a sludge discharging air
pipe, an air flushing
pipe, an inclined tee joint and a spray head. The top of the water inlet well sludge hopper is communicated with the top of the water outlet well sludge hopper through an inverted siphon. The device has the following advantages: 1, sludge deposited at the bottom of the sludge bucket is lifted to the ground by using an
air stripping method and can be pulled away by a
sewage suction
truck; 2, sludge deposited at the bottom of the inverted siphon is flushed into a sludge hopper of a water outlet well through
compressed air, and then the sludge is discharged out of the
system through an
air stripping method; 3, the same set of
air compression device can be adopted as an air source for desilting and sludge discharging, and the energy-saving effect is achieved; the sludge monitor in the water outlet well is used for monitoring the sludge thickness, automatic dredging and sludge discharging are started according to a
signal, time and labor are saved, and management is convenient.
