[0020] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a device for treating papermaking sludge in a paper mill, comprising a dewatering machine body 1, a support frame 2 is fixed to the bottom end of the dewatering machine body 1, a sewage discharge pipe 8 is fixedly connected to the bottom end of the dewatering machine body 1, a connecting barrel 5 is rotatably connected between the inner walls on both sides of the support frame 2, a plurality of mud outlets are provided at the bottom end of the connecting barrel 5, a plurality of treatment mechanisms corresponding to the mud outlets are arranged on the inner wall of the bottom end of the support frame 2, the sewage discharge pipe 8 is fixedly connected to one end of the top of the connecting barrel 5, a rotating shaft 6 is rotatably connected between the inner walls on both sides of the connecting barrel 5, an auger 7 is fixed to the outer wall of the rotating shaft 6, a collecting mechanism 3 is arranged at one end of the bottom of the dewatering machine body 1, the collecting mechanism 3 comprises a plurality of collecting boxes 302 fixed to the bottom of the dewatering machine body 1, and the collecting boxes 302 are close to the collecting boxes 302. An air inlet is provided at one end of the connecting barrel 5, and an exhaust pipe is fixedly connected to the other end of the collecting box 302. The odor enters a special treatment facility for treatment through the exhaust pipe. A mounting frame 307 is fixed to the inner wall of one end of the collecting box 302, and a suction fan 306 is rotatably connected to the mounting frame 307.
