[0022] Refer to Figures 1-4 , the high-pressure pneumatic power spiral dewatering machine includes a base 1. An upper end of the base 1 is provided with a box body 10. A semi-circular baffle 15 is provided inside the box body 10. Both sides of the semi-circular baffle 15 are provided with inclined plates. A feed port 22 is opened at an upper end of a left side of the box body 10. A discharge port 11 is opened on a side wall of a right side of the box body 10. A main rotating shaft 8 is rotatably connected through a side wall of a left side of the box body 10. A main drive shaft 13 is rotatably connected between an inner wall of a left side of the box body 10 and the discharge port 11. A spiral-shaped air outlet is opened on an outer wall of the main drive shaft 13. The main rotating shaft 8 is connected to the main drive shaft 13. A pushing mechanism for pushing the mixture is provided on an outer wall of the main drive shaft 13. The pushing mechanism includes an intermittent cross helix 19 and a continuous helix 21 provided on the outer wall of the main drive shaft 13. The ratio of the proportion of the intermittent cross helix 19 and the continuous helix 21 on the outer wall of the main drive shaft 13 is 3:1. By driving the intermittent cross bolt 19 and the continuous helix 21 to rotate through the main drive shaft 13, the two push the mixture forward, generating relative movement, and separating the solid and the liquid through their own spiral structures. The spiral dewatering machine is a device that realizes the solid-liquid separation of high-moisture materials by the extrusion of spiral blades.
[0023] An upper end of the base 1 is provided with a driving mechanism for driving the pushing mechanism. The driving mechanism includes a speed reducer 6 provided at an upper end of the base 1. An output end of the speed reducer 6 is connected to the main rotating shaft 8 through a shaft coupling 18. An upper end of the base 1 is provided with a coupling cover 9. The shaft coupling 18 is located inside the coupling cover 9.
[0024] At the upper end of the base 1, there is an installation block 2. At the upper end of the installation block 2, there is a spring washer 3. At the upper end of the spring washer 3, there is a power motor 4. At the end of the output shaft of the power motor 4, there is a rotating shaft 5. Both the outer wall of the input end of the rotating shaft 5 and the speed reducer 6 are provided with transmission belt pulleys 17. The two transmission belt pulleys 17 are connected by belt drive, and a belt pulley cover 7 is sleeved between the two transmission belt pulleys 17.
[0025] A cavity 14 is formed inside the main drive shaft 13. An air compressor 20 is provided outside the base 1. The output end of the air compressor 20 is communicated with the cavity 14. By forming a layer of tiny bubbles on the spiral surface, these bubbles can change the way the material contacts the spiral, reduce friction, and thus reduce the resistance of the speed reducer 6 and increase the effective torque. During the continuous generation and rupture of the bubbles, a passage will be formed by the main drive shaft 13, and the free water will also drain along the passage, thereby achieving efficient material dehydration.
[0026] At the lower end of the semi-circular baffle 15, a plurality of circumferentially arranged through grooves 16 are formed, and a drain port 12 is provided at the lower end of the box body 10.
[0027] When the utility model is in use, the solids in the mixture are separated by using the rotational movement of the main drive shaft 13. Specifically, the mixture first enters the inside of the screw dehydrator through the feed port 22. Inside, the main drive shaft 13 drives the intermittent cross bolts 19 and the continuous screw 21 to rotate, causing the two to push the mixture forward, generating relative movement, and separating the solid from the liquid through its own screw structure. The screw dehydrator is a device that uses the extrusion of screw blades to achieve solid-liquid separation of high-moisture materials. The moisture content of the material after being processed by the screw dehydrator is approximately around 60% - 70%.
[0028] To further reduce the moisture content of the processed material, the main drive shaft 13 of the screw dehydrator is changed from a solid shaft to a hollow shaft and spiral linear air outlets are opened, and medium-pressure air (1.6 MPa) is introduced to release bubbles, forming a layer of bubble film, thereby reducing the frictional resistance between the material and the spiral surface. This technology forms a layer of tiny bubbles on the spiral surface. These bubbles can change the way the material contacts the spiral, reduce friction, and thus reduce the resistance of the speed reducer 6 and increase the effective torque. During the continuous generation and rupture of the bubbles, a passage will be formed by the main drive shaft 13, and the free water will also drain along the passage, thereby achieving efficient material dehydration.
[0029] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the utility model.
