[0017] As Figure 1 shown, a liftable paddle mixer includes a paddle mixer body. The paddle mixer body includes a frame 1. The frame 1 is cooperatively provided with a sludge stirring tank 2. The sludge stirring tank 2 is cooperatively provided with a transmission system 3 with respect to the frame 1. The transmission system 3 is arranged above the sludge stirring tank 2. A stirring shaft 4 is arranged inside the sludge stirring tank 2 in cooperation with the transmission system 3. A mounting hole 5 is reserved at the top of the sludge stirring tank 2. A plurality of groups of stirring structures 6 are arranged on the stirring shaft 4. Bearing systems 7 are cooperatively arranged at both ends of the stirring shaft 4.

[0018] The transmission system 3 includes a driving motor 301. The driving motor 301 is arranged at the top of the sludge stirring tank 2. The driving motor 301 is cooperatively provided with a coupling 302. The transmission system 3 is also cooperatively provided with a speed reducer 303. The driving motor 301 is connected to the speed reducer 303 through the coupling 302.

[0019] The bearing system 7 includes a bottom bearing 701. The bottom bearing 701 is welded to the bottom of the sludge stirring tank 2. The bearing system 7 is further provided with a support bearing 702. The support bearing 702 is connected to the stirring shaft 4.

[0020] The stirring structure 6 is provided with a plurality of groups of stirring blades 601 around the stirring shaft 4. Each group of the stirring structures 6 located on the stirring shaft 4 is arranged at a certain distance.

[0021] The stirring blades 601 are made of stainless steel. The inclination angles between the multiple stirring blades 601 and the stirring shaft 4 are all 30 - 60°. The connection between the stirring blades 601 and the stirring shaft 4 is recessed inward.

[0022] An anti-corrosion layer 8 is provided on the inner side of the stirring tank.
