A connecting pipe is provided in the vertical rod, and the connecting pipe is located below the communicating hole, and the connecting pipe is connected with the communicating hole. Two drainage holes are provided on the vertical rod, and the drainage holes are located below the connecting pipe, and the drainage holes are connected with the connecting pipe. Four drainage holes are provided on the outside of the rotating ring, and the drainage holes on the rotating ring are connected with the lowest connecting pipe in the vertical rod.

[0012] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) The tank body is provided with a stirring mechanism and a heating mechanism. The unique structural design significantly improves the heating efficiency of the manure sludge. First, the vertical rod is equipped with a heating component, which heats the manure sludge while stirring it. This method of stirring and heating allows the heat to be transferred to the manure sludge more evenly, avoiding local overheating or insufficient heating. Second, the heating component in the liquid storage shell heats part of the manure sludge. Since the manure sludge in the liquid storage shell is small, the mass is small, and the heat capacity is also small, the temperature rises faster when absorbing the same amount of heat. When the heated manure sludge is squeezed out and mixed with the manure sludge in the tank body, the overall heat is increased. In addition, the manure sludge discharged from the drainage hole has a certain impact force, which can provide a stirring effect, further promoting the mixing and transfer of heat, making the temperature of the manure sludge in the tank body more uniform, thereby improving the heating efficiency of the entire fermentation process, providing more suitable temperature conditions for anaerobic fermentation, and helping to improve the fermentation efficiency and gas production. (2) The stirring mechanism of the device can achieve multi-stage stirring, which effectively improves the stirring effect of the manure sludge. When the vertical rod rotates in the tank, it drives the manure sludge to be initially stirred, so that it is evenly distributed in the tank. At the same time, the multiple stirring blades fixed on the outside of the liquid storage shell further stir the manure sludge during the rotation process, and there are multiple stirring holes on the stirring blades. These stirring holes can increase the turbulence of the fluid, so that the manure sludge is more fully mixed during the stirring process, avoiding sedimentation or stratification. In addition, three stirring cross bars are fixedly connected to the two upper liquid storage shells. When the liquid storage shells rotate, the stirring cross bars will also stir the manure sludge, so that the manure sludge discharged from the liquid storage shells is better mixed with the manure sludge in the tank. This multi-stage stirring method not only improves the uniformity of stirring, but also enhances the stirring force, so that the manure sludge can be fully mixed in the tank, providing good mixing conditions for anaerobic fermentation, which is conducive to improving fermentation efficiency and gas production quality.

[0019] The heating mechanism 5 includes three liquid storage shells 51 slidably arranged on the four vertical rods 42. The liquid storage shells 51 are also provided with a heating component for heating fecal sludge. A plurality of stirring blades 52 are fixedly arranged on the outside of the three liquid storage shells 51. A plurality of connecting vertical rods 53 are fixedly arranged between every two adjacent liquid storage shells 51. A plurality of springs 54 are fixedly arranged on the upper end of the uppermost liquid storage shell 51. The upper end of the spring 54 is fixedly connected to the bottom of the limit ring 44. The inside of the two upper liquid storage shells 51 is respectively fixedly connected with three stirring cross bars 56. The inside of the lowermost liquid storage shell 51 is fixedly connected with an extrusion block 55, and an inclined surface is provided on the side below the extrusion block 55.

[0021] The three sliding rings 431 are respectively arranged inside the liquid storage shell 51. The sliding rings 431 are slidingly connected to the liquid storage shell 51. When the lowermost liquid storage shell 51 is in contact with the rotating ring 41, the sliding ring 431 is located at the uppermost part of the liquid storage shell 51.

[0022] An arc-shaped rod 11 is fixedly connected to the lower part of the interior of the tank body 1 , and extrusion slopes 12 corresponding to the extrusion blocks 55 are respectively provided at both ends of the arc-shaped rod 11 .

[0023] The top cover mechanism 2 includes a top cover body 21 arranged above the tank body 1, and a drive motor 25 is fixedly arranged above the top cover body 21. The output end of the drive motor 25 passes through the top cover body 21 and is fixedly connected to a connecting horizontal plate 22. A connecting ring 23 is fixedly connected to the outside of the connecting horizontal plate 22, and an insertion rod 24 corresponding to the slot 451 is fixedly connected below the connecting ring 23.

[0024] The working principle of the present invention is as follows: manure sludge usually contains 70% to 99% water. When the tank body 1 is used to ferment and heat the manure sludge, the output end of the driving motor 25 drives the connecting ring 23 to rotate through the connecting horizontal plate 22. The connecting ring 23 drives the mounting ring 45 to rotate through the cooperation of the insertion rod 24 and the slot 451. The mounting ring 45 drives the rotating ring 41 to rotate at the bottom of the tank body 1 through the vertical rod 42. When the multiple vertical rods 42 rotate in the tank body 1, the manure and sludge are stirred. The heating components in the vertical rods 42 heat the manure sludge. The vertical rods 42 heat the manure sludge while stirring it, thereby improving the heating efficiency. When the vertical rod 42 rotates, the vertical rod 42 drives the liquid storage shell 51 to rotate, and the lowermost liquid storage shell 51 drives the extrusion block 55 to rotate. When the extrusion block 55 contacts the arc rod 11, the inclined surface below the extrusion block 55 contacts the extrusion inclined surface 12. The extrusion inclined surface 12 squeezes and pushes the extrusion block 55 to rise, and the extrusion block 55 drives the liquid storage shell 51 to rise. The liquid storage shell 51 drives the other two liquid storage shells 51 to rise upward through the connecting vertical rod 53. When the liquid storage shell 51 rises, the distance between the sliding ring 431 and the lower part of the liquid storage shell 51 gradually increases. At this time, the sliding ring 431 is pressed against the bottom of the liquid storage shell 51. 431 and the space above the liquid storage shell 51 form a negative pressure state, and the water in the feces and sewage sludge enters the connecting pipe 422 through the drainage hole 423, and then enters the connecting hole 421 from the connecting pipe 422, and then enters the connecting cavity 434 from the connecting hole 421, and then enters the sliding ring 431 and the space above the liquid storage shell 51 from the liquid inlet groove 433. The heating component in the liquid storage shell 51 heats part of the feces and sewage sludge. At this time, the feces and sewage sludge in the liquid storage shell 51 is less, the mass is small, the heat capacity is small, and the temperature rises faster when absorbing the same amount of heat. When the extrusion block 5 5 is separated from the arc rod 11, the spring 54 pushes the uppermost liquid storage shell 51 to move downward, and the uppermost liquid storage shell 51 drives the other two liquid storage shells 51 to move downward through the connecting vertical rod 53. At this time, the distance between the sliding ring 431 and the upper part of the liquid storage shell 51 is reduced, and the sliding ring 431 and the inner wall of the liquid storage shell 51 squeeze the feces and sludge. The feces and sludge are discharged into the tank body 1 from the discharge hole 423 through the liquid inlet groove 433, the connecting cavity 434, the connecting hole 421, and the connecting pipe 422. At this time, the heat of the feces and sludge heated by the liquid storage shell 51 is higher than that of the liquid storage shell 51. The feces and sewage sludge in the tank body 1 has high heat. After being stirred and mixed, the overall heat of the feces and sewage sludge in the tank body 1 is increased. After the feces and sewage sludge is squeezed and discharged from the drainage hole 423, the feces and sewage sludge discharged from the drainage hole 423 has a certain impact force, which can provide a certain stirring effect and improve the stirring efficiency. When the vertical rod 42 drives the liquid storage shell 51 to rotate, the two liquid storage shells 51 drive the stirring cross bar 56 to stir the feces and sewage sludge, so that the feces and sewage sludge discharged from the liquid storage shell 51 is better mixed with the feces and sewage sludge in the tank body 1, thereby improving the overall heating efficiency.

The scope of protection of the present invention is defined by the claims.
