[0029] The processing box 1 is provided with a feed port 4, which is connected to the upper part of the dehydration chamber 2;

[0030] The dehydration mechanism includes a spiral shaft 5, the diameter of the spiral blades 6 outside the spiral shaft 5 gradually decreases along the axial direction, the spiral blades 6 outside the spiral shaft 5 cooperate with the inside of the bucket-shaped dehydration chamber 2, and a servo motor 7 is installed at the left end of the spiral shaft 5, and the servo motor 7 is fixedly connected to the outside of the left end of the processing box 1.

[0031] Through the above technical scheme, the furfural residue is fed into the dehydration chamber 2 of the processing box 1 through the feed port 4, and the furfural residue is transported through the spiral shaft 5 of the dehydration chamber 2. Since the diameter of the spiral blades 6 outside the spiral shaft 5 gradually decreases along the axial direction, the spiral blades 6 of the spiral shaft 5 cooperate with the dehydration chamber 2 to compress the furfural residue, squeeze out the internal water, and discharge it through the drainage hole 8 at the bottom of the dehydration chamber 2, thereby realizing continuous dehydration of the furfural residue. After dehydration, it enters the drying chamber 3 for drying, thereby realizing continuous and rapid dehydration and drying of the furfural residue, and improving the processing efficiency of the furfural residue.

[0032] The dehydrated furfural residue is sent from the dehydration chamber 2 into the drying chamber 3 through the spiral blades 6 of the spiral shaft 5, and the driving rod 9 drives the stirring rod 13 to stir the furfural residue to disperse it. At the same time, the high-temperature gas water pipe 12 conveys hot air to the driving rod 9 through the pneumatic slip ring rotary joint 11. The hot air passes through the stirring rod 13 and is then sprayed into the drying chamber 3 through the jet holes 14 on the stirring rod 13. The furfural residue is stirred and dispersed while being dried. Since the drying chamber 3 is bucket-shaped, the dried furfural residue slides into the guide plate 16 through the bottom of the drying chamber 3 for output. The device can continuously dehydrate and evenly dry the furfural residue and then automatically output it. It is easy to operate and has high work efficiency.

[0033] Specifically, a plurality of drainage holes 8 are provided at the bottom of the dehydration chamber 2 and the drying chamber 3 , and the plurality of drainage holes 8 are evenly distributed at the bottom of the processing box 1 .

[0034] Through the above technical solution, the drainage holes 8 at the bottom of the dehydration chamber 2 and the drying chamber 3 are conducive to the drainage of moisture.

[0035] Specifically, the drying mechanism includes a driving rod 9 , and an air passage 10 is provided inside the driving rod 9 .

[0036] According to the above technical solution, the air passage 10 is provided inside the driving rod 9 , which is beneficial for conveying gas to the stirring rod 13 .

[0038] Through the above technical solution, the high-temperature gas water pipe 12 is conveniently connected to the driving rod 9 by rotation through the pneumatic slip ring rotary joint 11.

[0039] Specifically, a plurality of stirring rods 13 are distributed on the outer circumference of the driving rod 9 . The stirring rods 13 are hollow rods. Air jet holes 14 are arranged on the outer sides of the stirring rods 13 . The air jet holes 14 are connected to the inside of the stirring rods 13 .

[0040] Specifically, the plurality of stirring rods 13 are located inside the drying chamber 3 , and the plurality of stirring rods 13 are successively longer along the axial direction of the driving rod 9 .

[0044] When in use, the furfural residue is fed into the dehydration chamber 2 of the processing box 1 through the feed port 4, and the spiral shaft 5 in the dehydration chamber 2 rotates driven by the servo motor 7. Since the diameter of the spiral blades 6 outside the spiral shaft 5 gradually decreases along the axial direction, the spiral blades 6 cooperate with the dehydration chamber 2 to compress the furfural residue and squeeze out the internal moisture. The moisture is discharged through the drainage holes 8 evenly distributed at the bottom of the dehydration chamber 2, thereby realizing continuous dehydration of the furfural residue. The dehydrated furfural residue is fed from the dehydration chamber 2 into the drying chamber 3 through the spiral blades 6 of the spiral shaft 5. The driving rod 9 drives the stirring rod 13 to stir the furfural residue to disperse it. At the same time, the high-temperature gas water pipe 12 conveys hot air to the air channel 10 inside the driving rod 9 through the pneumatic slip ring rotary joint 11. The hot air passes through the hollow stirring rod 13 and then sprays into the drying chamber 3 through the jet hole 14 on the stirring rod 13. The furfural residue is stirred and dispersed while being dried. Since the drying chamber 3 is bucket-shaped, the dried furfural residue slides into the guide plate 16 through the bottom of the drying chamber 3 for output. In summary, the equipment can continuously dehydrate and evenly dry the furfural residue and then automatically output it, and has the advantages of convenient operation and high work efficiency.
