[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0040] Research has found that existing dryers put a batch of materials into the equipment at a time, pump the inside of the equipment to a certain vacuum degree, and then dry it. After waiting for the batch of materials to be dried, the next batch of materials is added to ensure that the internal vacuum degree is maintained within a certain range. Therefore, the materials cannot be fed continuously and the drying efficiency is low.

[0041] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by this disclosure for the above problems below should be the contributions made by the inventors to this disclosure during the disclosure process.

[0042] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. The following embodiments and features thereof may be combined with one another unless they conflict. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced to effectively illustrate the technical content.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0044] Based on the above research, Figure 1 The embodiment of the present disclosure provides a vacuum continuous conveying mechanism, comprising: a shell, a conveying pipe 1 inside the shell, the conveying pipe 1 can be optionally a hose, and the inside of the conveying pipe 1 is suitable for conveying materials. The shell also has a conveying disc 2 inside, and the conveying disc 2 is located on one side of the conveying pipe 1. Optionally, the rotation center of the conveying disc 2 is located at the center of the shell. The inner wall of the shell also has a conveying track 4, and the conveying track 4 is located on the side of the conveying pipe 1 away from the conveying disc 2. That is, the conveying pipe 1 is located between the conveying disc 2 and the conveying track 4. The points on the cross section of the conveying track 4 are at the same distance from the axis of the conveying disc 2. At the same time, the conveying disc 2 is provided with a plurality of conveying sections 3, and the distances from each conveying section 3 to the axis of the conveying disc 2 are also equal. Through the above arrangement, the conveying pipe 1 is filled with material, which is in the form of powder or fine particles. Then the conveying disc 2 rotates, thereby driving each conveying section 3 to rotate synchronously. Further, when the conveying disc 2 rotates until the conveying section 3 coincides with the conveying pipe 1, the two ends of the conveying section 3 squeeze the conveying pipe 1 to fit the conveying track 4, and the conveying section 3 closes the two ends of the overlapping part with the conveying pipe 1. At this time, since the inside of the overlapping part is filled with material, the material will squeeze out the air, and the conveying section 3 will close the two ends of the overlapping part, so that the inside of the overlapping part is sealed. On this basis, the conveying disc 2 continues to rotate, thereby pushing the material in the overlapping part of the above-mentioned conveying section 3 and the conveying pipe 1 forward along the conveying track 4.

[0045] Reference Figure 1To further ensure the continuity of material delivery through the conveying pipe 1, in at least one embodiment, the transfer sections 3 are evenly spaced along the circumference of the conveying disc 2. That is, as the conveying disc 2 rotates, the transfer sections 3 overlap with the conveying pipe 1 one by one, squeezing the material in the conveying pipe 1 and conveying it forward. This repetitive cycle achieves continuous material delivery through the conveying pipe 1.

[0046] Reference Figure 1 In at least one embodiment, a plurality of closure members 21 are provided on the conveyor tray 2, and the number of the closure members 21 is preferably four. A transporting area 3 is formed between two adjacent closure members 21, such as Figure 1 When both closure members 21 move onto the conveying track 4, they squeeze and seal the corresponding positions of the conveying pipe 1. The conveying area 3 formed between the two closure members 21 overlaps with the conveying pipe 1, and the overlapping portion forms a closed area, thereby achieving vacuum conveying of materials.

[0047] Reference Figure 2 In at least one embodiment, a roller 5 is mounted on the closure member 21. The roller 5 protrudes from the outer wall of the conveying tray 2. The closure member 21 contacts the feed pipe 1 via the roller 5, achieving rolling friction with the feed pipe 1 rather than sliding friction, thereby minimizing damage to the feed pipe 1 caused by the movement of the closure member 21.

[0048] In addition, when feeding materials with different characteristics, it may be necessary to replace the conveying pipe 1 with a different thickness or material. If the closure 21 is adaptively adjusted to the distance of the conveying track 4, there may be a risk that the closure 21 will crush the conveying pipe 1.

[0049] Reference Figure 2 To address the aforementioned issues, in at least one embodiment, the closure member 21 includes an extrusion seat 22. The conveyor tray 2 is radially provided with a plurality of mating grooves 23, within which the extrusion seat 22 slides. By designing the closure member 21 to be slidable and retractable along the conveyor tray 2, the distance between the extrusion seat 22 and the conveyor track 4 can be adjusted based on the actual thickness of the conveying pipe 1, without requiring a redesign or replacement of a conveyor tray 2 of a different size.

[0050] Reference Figure 2 To ensure that the pressing seat 22 maintains its compressive force on the feed pipe 1 after sliding, and that the roller 5 compresses and seals the feed pipe 1, in at least one embodiment, a pressing spring 24 is installed in the mating groove 23. One end of the pressing spring 24 is connected to the mating groove 23, and the other end is connected to the pressing seat 22. The pressing spring 24 pushes against the pressing seat 22, so that the pressing seat 22 drives the roller 5 to squeeze the feed pipe 1, thereby achieving a vacuum continuous feeding process.

[0051] In addition, the embodiment of the present disclosure also provides a drying system, using the vacuum continuous conveying mechanism as described above, referring to Figure 3 The drying system further includes a drying barrel 6 having a feed port 61 and a discharge port 62. Each of the feed port 61 and the discharge port 62 is equipped with a vacuum continuous conveying mechanism to achieve vacuum continuous loading and unloading of the drying barrel 6. Furthermore, to further ensure the vacuum level within the drying barrel 6, a vacuum pump 63 is installed in the drying barrel 6.

[0052] Reference Figure 3 In order to achieve the effect of drying the material inside the drying barrel 6, in some embodiments, a plurality of dryers 64 are installed on the outer wall of the drying barrel 6, and the dryers 64 can be microwave transmitters.

[0053] Reference Figure 3 In some embodiments, a spiral conveying mechanism 7 is installed inside the drying barrel 6. The spiral conveying mechanism 7 includes spiral blades. When the spiral conveying mechanism 7 rotates, the material is conveyed through the spiral blades.
