[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figures 1 to 4 As shown, this utility model provides a sludge removal device for sewage treatment. The device includes a treatment tank 1, a sludge removal assembly 2, a stirring assembly 3, and a transmission assembly 4.

[0020] This utility model provides a sludge discharge device for sewage treatment. Through the sludge discharge component 2, it can discharge sludge settled during sewage treatment, and apply pressure during discharge to squeeze out the internal sewage, shortening the sludge drying time and facilitating sludge reprocessing.

[0021] In this embodiment of the utility model, during use, the sludge discharge motor 21 is energized to output power, causing the power shaft 22 to drive the sludge discharge blades 23 to transport the sludge. As the pitch of the sludge discharge blades 23 gradually decreases, the pressure during the sludge transport process gradually increases, causing the sewage inside the sludge to be squeezed and discharged through the drain hole 242. The stirring shaft 34 is synchronously driven by the forces of the first pulley 31, the fixed belt 32, and the stirring pulley 33, causing the stirring rod 35 to stir the sludge and prevent the sludge from clogging at the discharge hole 12.
