[0028] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a sludge recycling and dewatering device, including a frame 1, a drying and dewatering device 2, a driving device 3, an air extraction device 4, a heating device 5, and a push-pull device 6.
[0029] The frame 1 is equipped with the drying and dehydration device 2, the air extraction device 4, and the heating device 5. The drying and dehydration device 2 is equipped with the driving device 3 on its side wall. The drying and dehydration device 2 includes a cylinder 21, a cylinder cover 22, and a spin-drying cylinder 24. One end face of the cylinder 21 has an opening. The spin-drying cylinder 24 is slidably connected to the inner cavity of the cylinder 21. The cylinder cover 22 is located at the opening of the cylinder 21. The air extraction device 4 is connected to the inner cavity of the cylinder 21. The heating device 5 is connected to the inner cavity of the cylinder 21. The pushing end of the push-pull device 6 is connected to the spin-drying cylinder 24 through a bearing seat.
[0030] The end of the spin-drying cylinder 24 furthest from the push-pull device 6 is an open end. The cylinder cover 22 has a flange, the inner side of which is used to connect to the side wall of the open end of the spin-drying cylinder 24. The inner side wall of the flange of the cylinder cover 22 is provided with a bearing to reduce the friction of the spin-drying cylinder 24.
[0031] Furthermore, the drying and dehydration device 2 also includes a heating resistor 23, which is disposed on the inner wall of the cylinder 21. The frame 1 is provided with a rotary joint to prevent the wires of the internal heating resistor 23 from becoming tangled.
[0032] Furthermore, the drying and dehydration device 2 also includes an isolation layer 25 and a drain outlet 26. The isolation layer 25 is provided on the inner wall of the cylinder 21. The heating resistor 23 is disposed between the inner wall of the cylinder 21 and the isolation layer 25. The drain outlet 26 is provided at the bottom of the cylinder 21 away from the cylinder cover 22, and the drain outlet 26 communicates with the inner cavity of the cylinder 21. A collection box is also provided below the drain outlet 26 to prevent splashing.
[0033] Furthermore, the driving device 3 includes a motor 31 and a drive wheel 32. The motor 31 is fixedly mounted on the top of the cylinder 21. The driving end of the motor 31 is connected to the drive wheel 32 via a transmission belt. The spin-drying cylinder 24 is rotatably connected to a bearing seat. The spin-drying cylinder is provided with a push rod 241. One end of the push rod 241 is connected to the pushing end of the push-pull device 6, and the other end of the push rod 241 is fixedly connected to the bearing seat of the spin-drying cylinder 24.
[0034] Furthermore, the cylinder cover 22 includes a movable cover 221 and a cover body 222. The cover body 222 has a sliding opening at its center. The cover body 222 is detachably connected to the cylinder body 21, and the movable cover 221 is hinged to the outer end face of the cover body 222. The circumferential diameter of the movable cover 221 needs to be slightly larger than the circumferential diameter of the spin-drying cylinder 24. This design does not affect the effect of the spin-drying cylinder 24 when rotating, and also facilitates the sliding of the spin-drying cylinder 24 through the push-pull device 6.
[0035] Furthermore, the air extraction device 4 includes a fan 41, a purification chamber 42, and an air suction pipe 43.

These filter chambers are filled with corresponding filter materials, purifying the air through physical adsorption and chemical reaction.
[0036] Furthermore, the heating device 5 includes a pump body 51 and a heating pipe 52. The output port of the pump body 51 is connected to one end of the heating pipe 52, and the other end of the heating pipe 52 passes through the side wall of the cylinder 21 and connects to the inner cavity. A hot air furnace is connected to the input port of the pump body 51, and the type of hot air furnace is not limited in this utility model. The hot air generated by the hot air furnace is drawn into the heating pipe 52 through the pump body 51, and the heating pipe 52 introduces the hot air into the cylinder 21.
[0037] Working principle:
[0038] First, open the movable cover 221 and add sludge into the spin dryer 24.
[0039] The heating device 5 is turned on to introduce steam into the cylinder 21, and the heating resistor 23 is turned on simultaneously to achieve dual heating. At this time, the drive device 3 is turned on to rotate the spin-drying cylinder 24 to achieve the spin-drying effect. The water spun out of the sludge flows into the drain outlet 26.
[0040] After the heating device 5 has been working for a certain period of time, the exhaust device 4 is turned on and the heating device 5 is turned off to draw out the turbid gas generated in the cylinder 21, which is then discharged after being treated by the purification box 42.
[0041] After completing the above work, open the movable cover 221 and open the push-pull device 6 to push the spin dryer 24 out of the inner cavity of the cylinder 21, so that the staff can collect the treated sludge.
