[0031] Please see Figure 1-7 This utility model provides a technical solution: a sludge drying device with an auxiliary dispersion structure, including a heating cylinder 1, a dispersion box 2, a drive motor 3, a stirring cylinder 4, a filter baffle 5, a transmission gear 6, a linkage gear 7, a guide gear 8, a first sprocket 9, a horizontal gear 10, a second sprocket 11, a third sprocket 12, a support baffle 13, a fourth sprocket 14, and a water outlet roller 15. The heating cylinder 1 has two dispersion boxes 2 fixedly connected to its upper side surface. The upper surface of each dispersion box 2 has a feed inlet, and the lower surface of the heating cylinder 1 has a discharge outlet. The lower surface of each dispersion box 2 also has a drainage outlet. When using this device, raw materials are first added through the feed inlets on the upper surfaces of the two dispersion boxes 2, allowing the raw materials to be separated from the water flow by the filter baffle 5. The water flow is then discharged from the water outlet at the lower end of the dispersion box 2. The raw materials are guided by the filter baffle 5 into the heating cylinder 1 for heating and drying, and finally, the raw materials are discharged from the discharge outlet at the lower end of the heating cylinder 1.

[0032] A drive motor 3 is fixed on the upper surface of the heating cylinder 1. A stirring cylinder 4 is provided on the top surface of the cavity of the heating cylinder 1.

The linkage gears 7 are rotatably connected to the heating cylinder 1. The first sprocket 9 is rotatably connected to the heating cylinder 1. The guide gear 8 is meshed with the horizontal gear 10. During operation, the drive motor 3 drives the transmission gear 6 and the stirring cylinder 4 to rotate, which facilitates the stirring of the raw materials by the blades on the surface of the stirring cylinder 4, thereby increasing the drying efficiency of the raw materials. As the transmission gear 6 rotates, it facilitates the rotation of the two linkage gears 7.

[0033] A transmission gear 6 is provided on the upper surface of the heating cylinder 1. Two linkage gears 7 are connected to the upper surface of the heating cylinder 1. A guide gear 8 is fixedly connected to the upper end of the shaft of the linkage gear 7. A first sprocket 9 is installed at the upper end of the heating cylinder 1.

A transmission chain is provided between the outer surface of the first sprocket 9 and the outer surface of the third sprocket 12. Wheel 11 is rotatably connected to the dispersion box 2. It drives the guide gear 8 to rotate through the linkage gear 7. The guide gear 8 meshes with the horizontal gear 10 above, so that the horizontal gear 10 drives the first sprockets 9 at both ends of the shaft to rotate. The first sprockets 9 drive the third sprocket 12 to rotate through the transmission chain, so that the second sprocket 11, which is coaxial with the third sprocket 12, rotates synchronously. The transmission chain on the outer surface of the third sprocket 12 extends into the opening on the surface of the support baffle 13, and the transmission chain on the outer surface of the third sprocket 12 will drive the fourth sprocket 14 to rotate.

The fourth sprocket 14 is installed on the inner wall of the groove in the support baffle 13. A water outlet roller 15 is positioned between two support baffles 13. The upper end of the groove in the support baffle 13 is open. The fourth sprocket 14 is rotatably connected to the support baffle 13. The fourth sprocket 14 is connected to the second sprocket 14. In the corresponding configuration, a sprocket is provided between the outer surface of the fourth sprocket 14 and the outer surface of the second sprocket 11. The water outlet pressure roller 15 is rotatably connected to the support baffle 13, and the rotating shaft of the water outlet pressure roller 15 passes through the surface of the support baffle 13. The rotating shaft of the water outlet pressure roller 15 is fixedly connected to the rotating shaft of the fourth sprocket 14. The rotation of the fourth sprocket 14 will drive the water outlet pressure roller 15 to rotate relative to the support baffle 13. The linkage reduces energy consumption. At the same time, the rotation of the water outlet pressure roller 15 squeezes and drives the raw material, which facilitates the improvement of the water output effect and increases the practicality of this device.

[0035] Working principle: When using this sludge drying device with an auxiliary dispersion structure, the raw material is introduced through the dispersion box 2, and the filter baffle 5 filters and discharges the water. Then the raw material enters the heating cylinder 1 for drying. Subsequently, the drive motor 3 drives the transmission gear 6 and the stirring cylinder 4 to rotate and stir the raw material for drying. At the same time, the transmission gear 6 drives the linkage gear 7 and the guide gear 8 to rotate, which facilitates the guide gear 8 to drive the horizontal gear 10 and the first sprocket 9 to rotate. The first sprocket 9 drives the third sprocket 12 and the second sprocket 11 to rotate through the transmission chain. The second sprocket 11 drives the fourth sprocket 14 and the water outlet roller 15 to rotate through the transmission chain, so that the water outlet roller 15 squeezes and drains the raw material, which increases the overall practicality.
