Referring to fig. 1-2, a sludge discharging device of a sedimentation tank comprises a sludge discharging pipe main body 1 with a tubular structure, wherein a plurality of expansion sludge discharging pipes 2 are arranged at the bottom of the sludge discharging pipe main body 1, the expansion sludge discharging pipes 2 are communicated with the sludge discharging pipe main body 1, specifically, the diameter of the small end of each expansion sludge discharging pipe 2 is 20mm, the diameter of the large end is 45mm, the length of each expansion sludge discharging pipe is 283mm, an included angle alpha between each expansion sludge discharging pipe 2 and the sludge discharging pipe main body 1 is 45 degrees, and the diameter of each expansion sludge discharging pipe 2 is gradually reduced from one end communicated with the sludge discharging pipe main body 1 to the other end.

After the original sludge discharge hole 4 is changed into the expansion sludge discharge pipe 2 in the application, the original sludge discharge hole 4 is changed into a water injector, when the sludge discharge pipe main body 1 enters the expansion sludge discharge pipe 2, the sludge discharge efficiency is obviously improved because one end of the expansion sludge discharge pipe 2, which is communicated with the sludge discharge pipe main body 1, is larger than the other end, and the principles that the flow coefficient of the inlet of the expansion nozzle is large, the flow coefficient is high and the vacuum degree at the reduced section is high in the hydraulics are utilized, so that the sludge cannot stay too long in the expansion sludge discharge pipe 2.
