[0020] The atomizing and wetting device 100 for plant fiber raw materials of this utility model can atomize the liquid through the spraying mechanism 2, thereby dispersing the liquid into tiny droplets that come into contact with the raw material. Then, the double-spiral stirring paddle 3 is driven by the rotary drive mechanism 4 to continuously stir. Due to the uniformity of axial and radial stirring of the double-spiral stirring paddle 3, the liquid and plant fiber raw material are uniformly mixed.

[0021] Please see Figure 2 In one embodiment, the upper part of the shell 1 has a square structure, and the lower part of the shell 1 has a semi-circular structure. By setting the lower part of the shell 1 to a semi-circular structure, it is beneficial for the material to collect at the bottom of the shell 1 during discharge.

[0022] Please see Figure 1 and Figure 2 In one embodiment, the spraying mechanism 2 includes an atomizing liquid pipe 21 and nozzles 22. The atomizing liquid pipe 21 passes through the mixing space 11, and a plurality of nozzles 22 are respectively disposed on the atomizing liquid pipe 21. Specifically, the atomizing liquid pipe 21 is located at the top of the mixing space 11 and is parallel to the double-ribbon stirring paddle 3, further ensuring the uniformity of mixing. The nozzles 22 are distributed along the length of the atomizing liquid pipe 21. The number of nozzles 22 can be one or more, and the number of atomizing liquid pipes 21 can also be one or more.

[0023] Please see Figure 1 In one embodiment, the spraying mechanism 2 further includes a valve 23, which is disposed on the portion of the atomizing liquid pipe 21 that extends out of the housing 1. The valve 23 is used to control the opening and closing of the atomizing liquid pipe 21, thereby controlling the amount of liquid atomized in the mixing space 11.

[0024] Please see Figure 1In one embodiment, the double-ribbon agitator 3 includes a rotating shaft 31 and a double-ribbon section 32. The double-ribbon section 32 is disposed on the rotating shaft 31, and both ends of the rotating shaft 31 pass through the housing 1. The output end of the rotary drive mechanism 4 is connected to the rotating shaft 31. Specifically, the atomizing liquid pipe 21 is parallel to the rotating shaft 31, and a gap is left between the double-ribbon section 32 and the semi-circular lower half of the housing 1. The gap size is in the range of 2-50mm, preferably in the range of 5-15mm. Further, a sealing element 311 and a bearing element 312 are provided at the position where the rotating shaft 31 passes through the housing 1 to ensure the sealing and stability of the structure. Specifically, the sealing element 311 is sleeved on the rotating shaft 31 and seals the position between the rotating shaft 31 and the housing, and the bearing element 312 is sleeved on the rotating shaft 31 and located on one side of the sealing element 311. More specifically, both ends of the rotating shaft 31 extend out of the housing 1, and both ends of the rotating shaft 31 are provided with a seal 311 and a bearing 312.

[0025] Please see Figure 1 and Figure 2 In one embodiment, the atomizing and wetting device 100 for plant fiber raw materials of this invention further includes a discharge port cover 5. The lower part of the housing 1 is provided with several discharge ports 13 communicating with the mixing space 11. Each discharge port 13 is provided with a discharge port cover 5, which is used to seal the discharge port 13. The discharge port 13 can be opened by opening the discharge port cover 5, allowing the moistened material after uniform mixing of the liquid and the plant fiber raw material to be discharged from the discharge port 13. The number of discharge ports 13 can be one or more.

[0026] Please see Figure 1 and Figure 2 In one embodiment, the atomizing and wetting device 100 for plant fiber raw materials of this utility model further includes a cap opening and closing drive mechanism 6. The cap opening and closing drive mechanism 6 is disposed on the housing 1, and each outlet cap 5 is correspondingly connected to the cap opening and closing drive mechanism 6. The cap opening and closing drive mechanism 6 is used to drive the outlet cap 5 to move and open or close the outlet 13. The cap opening and closing drive mechanism 6 can adopt an existing cylinder structure, using the extension and retraction of the cylinder structure to drive the outlet cap 5 to move and open or close the outlet 13, but is not limited thereto. Specifically, a bracket 14 is provided at the lower part of the housing 1, the cap opening and closing drive mechanism 6 is disposed on the bracket 14, a support platform 15 is provided on the side of the housing 1, and a rotation drive mechanism 4 is disposed on the support platform 15.

[0027] Combination Figure 1 and Figure 2 The specific working principle of the atomizing and wetting device 100 for plant fiber raw materials of this utility model is as follows:

[0028] Close the outlet cap 5, and add the air-dried plant fiber raw material, which has been shredded, cut to a certain length, and weighed, into the mixing space 11 of the shell 1 through the inlet 12. Drive the double-ribbon agitator 3 to agitate the raw material through the rotary drive mechanism 4. Open the valve 23 of the spray mechanism 2, and allow the liquid from the metering pump to flow into the atomizing liquid pipeline 21 according to the liquid-solid ratio. After flowing through the nozzle 22, it forms atomized liquid particles. These liquid particles come into contact with the continuously agitated plant fiber raw material and are absorbed. Since the double-ribbon agitator 3 has dual agitation functions in the axial and radial directions, the plant fiber raw material can be evenly contacted with the atomized droplets to achieve uniform wetting. After all the liquid has been atomized, open the outlet cap 5. Under continuous agitation, the wetted plant fiber raw material is discharged from the outlet 13 of the shell 1. Turn off the rotary drive mechanism 4 and close the valve 23 of the spray mechanism 2 to complete one atomization and wetting operation.

[0029] In summary, the atomizing and wetting device 100 for plant fiber raw materials of this utility model can atomize the liquid through the spray mechanism 2, thereby dispersing the liquid into tiny droplets that come into contact with the raw material. Then, the double-spiral stirring paddle 3 is driven by the rotary drive mechanism 4 to continuously stir. Due to the uniformity of axial and radial stirring of the double-spiral stirring paddle 3, the liquid can be uniformly mixed with a large amount of plant fiber raw material even when the liquid-solid ratio is very small, thereby obtaining a uniform wetting solid-liquid mixture, which has a very good practical effect.

Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
