[0031] The utility model is further described below in conjunction with the accompanying drawings:

[0032] like Figure 1-Figure 9 As shown, a sludge drying treatment device includes a sealing mechanism 1 for storing sludge and a power mechanism 2 for providing power, a mixing mechanism 3 for cooperating with the sealing mechanism 1 to stir and dry the sludge, and an adjusting mechanism 4 for cooperating with the mixing mechanism 3 to improve the mixing efficiency of the heat source, wherein the mixing mechanism 3 is installed inside the sealing mechanism 1, and the adjusting mechanism 4 is installed on the mixing mechanism 3;

[0033] The mixing mechanism 3 includes a power shaft 31, which is arranged to penetrate the sealing mechanism 1 along the axial direction. A hollow cylinder 32 is arranged outside the power shaft 31. A plurality of stirring rods 33 are installed on the hollow cylinder 32 in the inner area of ​​the sealing mechanism 1. A stirring block 34 is installed on the stirring rod 33 at one end away from the hollow cylinder 32. The stirring rod 33 and the hollow cylinder 32 are both hollow structures. The stirring rod 33 is connected to the hollow part inside the hollow cylinder 32. The stirring rod 33 is evenly formed with a first air outlet 331.

[0034] The adjusting mechanism 4 includes an inner adjusting cylinder 44, which is installed inside the stirring rod 33 and is rotatably connected to the stirring rod 33. The outer wall of the inner adjusting cylinder 44 is in close contact with the inner wall of the stirring rod 33. A second air outlet 441 is provided on the inner adjusting cylinder 44 corresponding to the position of the first air outlet 331. A connecting rod 45 is installed inside the inner adjusting cylinder 44. A sealing cylinder 41 is connected to the top of the connecting rod 45. The sealing cylinder 41 is connected to the stirring rod 33 through an elastic component. The outside of the sealing cylinder 41 is fixedly connected to the stirring block 34.

[0035] In this embodiment, the elastic component includes a connecting ring 42 and a force storage spring 43. The connecting ring 42 is fixedly connected to the top of the stirring rod 33. The sealing tube 41 is wrapped around the outside of the connecting ring 42. A groove for accommodating the connecting ring 42 and the force storage spring 43 is formed inside the sealing tube 41. The force storage spring 43 is installed in the groove of the sealing tube 41. The two ends of the force storage spring 43 are respectively fixedly connected to the connecting ring 42 and the sealing tube 41.

[0036] In this embodiment, when the inner adjustment tube 44 is at the initial position, the overlapping area between the second air outlet 441 and the first air outlet 331 is 20%.

[0037] In this embodiment, the sealing mechanism 1 includes a base 11, side panels 14 are installed on both sides of the upper end of the base 11, a mixing drum 12 is installed at the center of the side panels 14, a discharge assembly 13 is installed on one of the side panels 14, and the power mechanism 2 is installed on the outside of the other side panel 14.

[0038] In this embodiment, four central stirring blades 35 are evenly mounted on the outer circumferential surface of the hollow cylinder 32 .

[0039] In this embodiment, the power shaft 31 is fixedly connected to the hollow cylinder 32 via a hollow frame, and both the power shaft 31 and the hollow cylinder 32 are connected to the side plate 14 via bearings.

[0040] In this embodiment, the stirring block 34 is a triangular structure, and the sealing cylinder 41 is eccentrically installed in the stirring block 34 .

[0041] Working principle: the power shaft 31 is connected to the power mechanism 2, the hollow cylinder 32 is connected to the external heat source, and the dry hot air is ejected through the first air outlet 331 through the hollow of the hollow cylinder 32 and the stirring rod 33, thereby drying the stirred sludge;

[0042] When the power shaft 31 drives the stirring block 34 to rotate through the hollow cylinder 32 and the stirring rod 33, the stirring block 34 contacts the wet sludge during the rotation. At this time, because the axis of the sealing cylinder 41 is eccentrically installed on the stirring block 34, the stirring block 34 begins to deflect around the axis of the sealing cylinder 41 after being resisted by the sludge. The higher the wetness of the sludge, the greater the resistance, and the greater the deflection angle of the stirring block 34. Figures 4 to 7As shown, when the stirring block 34 is deflected, the connecting rod 45 and the inner adjusting cylinder 44 are driven to rotate through the sealing cylinder 41. Then, when the rotation angle of the inner adjusting cylinder 44 is larger, the overlapping area between the second air outlet 441 on the inner adjusting cylinder 44 and the first air outlet 331 on the stirring rod 33 is larger, which means that the opening of the first air outlet 331 is larger, and more dry air source can be sprayed out, so the sludge in this area receives more dry hot air, and the sludge in other areas that is not so moist receives relatively less dry air, which improves the drying of this area, improves the efficiency of using the heat source, and thus improves the processing efficiency of sludge drying. At the same time, the connecting ring 42 with an elastic structure is used to provide elastic swing for the stirring block 34, thereby providing multiple mixing forces while stirring the sludge, thereby improving the stirring effect.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
