To better connect the first treatment tank 3 and the base 1, one end of the base 1 away from the support leg 2 is fixedly connected with a second treatment tank 11. A heating wire 5 is arranged inside the first treatment tank 3 to dry the sludge in the heating wire 5. A stirring shaft 6 is rotatably connected inside the first treatment tank 3. The stirring shaft 6 turns the sludge in the first treatment tank 3 to prevent the sludge from accumulating and resulting in low drying efficiency. A scraper 7 is fixedly connected to the outer side of the stirring shaft 6. When the stirring shaft 6 rotates, it drives the scraper 7 to rotate, and the scraper 7 rotates to scrape the sludge adhering to the inner wall surface of the first treatment tank 3. A first connecting pipe 10 is fixedly connected between the first treatment tank 3 and the second treatment tank 11. A check valve is arranged inside the first connecting pipe 10 to allow the gas in the first treatment tank 3 to enter the second treatment tank 11. A partition 12 is fixedly connected inside the second treatment tank 11. One end of the partition 12 is V-shaped to make the separated water flow better to the bottom of the second treatment tank 11. Baffles 14 are staggered between the top of the partition 12 and the second treatment tank 11. The staggered arrangement of the baffles 14 forms a channel to extend the residence time of the gas in the second treatment tank 11 and better comprehensively treat the gas. A condensing pipe 17 is fixedly connected inside the second treatment tank 11 and at the directly below of the first connecting pipe 10 to condense the water vapor generated during drying into liquid water by low temperature. A drying plate 16 is fixedly connected to the side of the baffle 14 away from the condensing pipe 17 to adsorb the residual moisture in the gas. An activated carbon plate 15 is fixedly connected to one end of the second treatment tank 11 away from the condensing pipe 17 to adsorb the odor in the gas and reduce the odor generated during sludge treatment. An exhaust hole 21 is provided on one side of the second treatment tank 11 and below the activated carbon plate 15 to better discharge the treated gas to the outside. A connection hole 13 penetrating its surface is opened on one side of the partition 12 directly below the condensing pipe 17, and the condensed water enters the bottom of the second treatment tank 11 through the connection hole 13. The bottom of the base 1 is fixedly connected with a mounting seat 24 through a connecting column 44. A third treatment tank 25 is fixedly connected between the top of the mounting seat 24 and the base 1. The third treatment tank 25 treats the dried sludge.

[0029] Furthermore, a water tank 23 is fixedly connected to one side of the second processing tank 11. One end of the condensing pipe 17 passes through one side of the water tank 23 and extends into the interior of the water tank 23, so that the water in the condensing pipe 17 returns to the water tank 23 for repeated cooling use. An installation box 19 is fixedly connected to one side of the water tank 23. A water pump 20 is fixedly connected to the interior of the installation box 19.

One end of the water pump 20 is fixedly connected to a refrigerator 18. The water pump 20 sends the pumped water to the refrigerator 18 for cooling treatment. The end of the condensing pipe 17 far from the water tank 23 passes through one side of the installation box 19 and is connected to the refrigerator 18, better sending the cooled water into the condensing pipe 17 to keep the temperature of the condensing pipe 17 at a certain value.

[0030] Furthermore, a fixed box 39 is rotatably connected to the bottom of the stirring shaft 6. A fixed column 38 is slidably connected to the interior of the stirring shaft 6. The fixed column 38 moves along the interior of the stirring shaft 6, and the rotation of the stirring shaft 6 drives the fixed column 38 to rotate. A first limiting plate 40 is fixedly connected to the bottom of the fixed column 38. The movement of the fixed column 38 drives the first limiting plate 40 to move. A second limiting plate 41 is fixedly connected to the bottom of the interior of the fixed box 39. When the bottom of the first limiting plate 40 contacts the top of the second limiting plate 41, the first limiting plate 40 drives the second limiting plate 41 to rotate. An electric telescopic rod 37 is fixedly connected to the interior of the stirring shaft 6. The output end of the electric telescopic rod 37 is fixedly connected to the fixed column 38. When the electric telescopic rod 37 is turned on, it drives the fixed column 38 to move.

[0031] Furthermore, a conveying shaft 42 is rotatably connected to the interior of the conveying pipe 9. The top of the conveying shaft 42 passes through the bottom of the fixed box 39 and extends into the interior of the fixed box 39 and is fixedly connected to the second limiting plate 41. The rotation of the second limiting plate 41 drives the conveying shaft 42 to rotate. A spiral blade 43 is arranged on the outer side of the conveying shaft 42. The rotation of the conveying shaft 42 drives the spiral blade 43 to rotate. The rotation of the spiral blade 43 conveys the dried sludge.

[0032] Further, a first rotating rod 28 and a second rotating rod 29 are rotatably connected inside the third treatment box 25. A first crushing roller 26 is fixedly connected to the outside of the first rotating rod 28. The first rotating rod 28 rotates to drive the first crushing roller 26 to rotate. A second crushing roller 27 is fixedly connected to the outside of the second rotating rod 29. The second rotating rod 29 rotates to drive the second crushing roller 27 to rotate. One end of each of the first rotating rod 28 and the second rotating rod 29 passes through one side of the third treatment box 25 and is fixedly connected to a gear 31. There are two groups of gears 31, and the two groups of gears 31 are meshed and connected. Under the action of the gears 31, the first rotating rod 28 and the second rotating rod 29 rotate simultaneously. A second motor 35 is fixedly connected to one side of the third treatment box 25. One end of the second rotating rod 29 passes through one side of the third treatment box 25 and is fixedly connected to the output end of the second motor 35. After the second motor 35 is turned on, it drives the second rotating rod 29 to rotate.

[0033] Further, a first motor 4 is fixedly connected to the top of the first treatment box 3. The top of the stirring shaft 6 passes through the top of the first treatment box 3 and is fixedly connected to the output end of the first motor 4. After the first motor 4 is turned on, it drives the stirring shaft 6 to rotate.

[0034] Further, a plurality of stirring rods 8 are fixedly connected to the outside of the stirring shaft 6. The stirring shaft 6 rotates to drive the stirring rods 8 to rotate, further strengthening the turning of the sludge. A water outlet 22 is fixedly connected to one side of the second treatment box 11 to discharge the condensed water.

[0035] Further, a fourth treatment box 33 is fixedly connected to the top of the mounting seat 24. A second connecting pipe 34 is fixedly connected between the inside of the fourth treatment box 33 and the third treatment box 25. A blower 32 is fixedly connected to the top of the mounting seat 24. One end of the blower 32 passes through one side of the fourth treatment box 33 and extends into the fourth treatment box 33. After the blower 32 is turned on, the dust generated during the crushing process of the first crushing roller 26 and the second crushing roller 27 enters the fourth treatment box 33 through the second connecting pipe 34. A second collection box 45 is detachably connected above the end of the blower 32 inside the fourth treatment box 33. A filter plate 36 is provided at the bottom of the second collection box 45. The filter plate 36 filters the gas entering the blower 32, so that the dust and impurities stay in the second collection box 45, preventing the dust and impurities from entering the blower 32 and damaging the blower 32.

[0036] Further, a first collection box 30 is detachably connected inside the third treatment box 25. The first collection box 30 collects the crushed sludge to prevent the sludge from drying and becoming too large in volume, making it difficult to handle centrally later.

[0037] During use, pour the sludge into the first treatment tank 3, close the inlet at the top of the first treatment tank 3, and turn on the first motor 4, heating wire 5, cooler 18, and water pump 20. The heating wire 5 dries the sludge in the first treatment tank 3. The first motor 4 drives the stirring shaft 6 to rotate. While the stirring shaft 6 rotates, it drives the scraper 7 and the stirring rod 8 to rotate. The stirring rod 8 flips the sludge in the first treatment tank 3 to prevent the sludge from accumulating inside the first treatment tank 3 and affecting the drying effect. The scraper 7 scrapes off the sludge adhering to the inner wall surface of the first treatment tank 3. The gas generated during the heating process and the water vapor generated by water evaporation enter the second treatment tank 11 along the first connecting pipe 10. The water pump 20 pumps the water in the water tank 23 into the cooler 18. The cooler 18 cools the water, and the treated water enters the condensing pipe 17. The water in the condensing pipe 17 returns to the water tank 23 through the other end and repeats the cooling process to enter the condensing pipe 17, controlling the temperature of the condensing pipe 17 at a certain value. The gas and water vapor in the first connecting pipe 10 enter the second treatment tank 11 and contact the condensing pipe 17 first, condensing the water vapor into liquid water through low temperature. The water enters the bottom of the second treatment tank 11 through the connecting hole 13, and the gas continues to move along the channel formed by the baffle 14. The drying plate 16 adsorbs the remaining moisture, and the activated carbon plate 15 adsorbs the odor in the gas, reducing the foul smell generated during sludge treatment. The treated gas is discharged to the outside through the exhaust hole 21. After the sludge is dried, turn on the electric telescopic rod 37, the fan 32, and the second motor 35. The electric telescopic rod 37 drives the first limiting plate 40 to move through the fixed column 38, making the teeth at the bottom of the first limiting plate 40 fit with the teeth at the top of the second limiting plate 41. At this time, the rotation of the stirring shaft 6 drives the second limiting plate 41 and the fixed box 39 to rotate through the fixed column 38 and the first limiting plate 40. The rotation of the second limiting plate 41 drives the conveying shaft 42 and the spiral blade 43 to rotate. The spiral blade 43 rotates to send the dried sludge in the first treatment tank 3 into the third treatment tank 25 through the conveying pipe 9. The second motor 35 drives the second crushing roller 27 and the gear 31 to rotate through the second rotating rod 29. The two groups of gears 31 rotate simultaneously, making the first rotating rod 28 and the second rotating rod 29 drive the first crushing roller 26 and the second crushing roller 27 to rotate simultaneously to crush the sludge falling from the bottom of the conveying pipe 9, preventing the volume of the dried sludge from being too large and wasting too much storage space, and also facilitating subsequent centralized treatment of the sludge. The crushed sludge falls into the first collection box 30. The fan 32 is turned on, and the dust generated during the crushing process of the first crushing roller 26 and the second crushing roller 27 enters the fourth treatment tank 33 through the second connecting pipe 34. The filter plate 36 filters the gas entering the fan 32, making the dust and impurities stay in the second collection box 45 to prevent the dust and impurities from entering the fan 32 and damaging the fan 32.
