[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] This utility model embodiment provides a distillation vessel with uniform heating, such as... Figure 1 and 3 As shown, the assembly includes a vessel body 1, a stirring assembly 2, and a heating assembly 3. The vessel body 1 has an inner cavity 11. The top of the vessel body 1 has an inlet 12 and an outlet 13 communicating with the inner cavity 11 on both sides. The bottom of the vessel body 1 has a waste outlet 14 communicating with the inner cavity 11. The stirring assembly 2 includes a stirring shaft 21 arranged along the central axis of the vessel body 1 inside the inner cavity 11. The outer wall of the stirring shaft 21 has several stirring blades 22. The stirring shaft 21 has a first mounting cavity 211 inside, and the stirring blades 22 have a mounting cavity 211. The second mounting cavity 221 is connected to the mounting cavity 211. The heating assembly 3 includes an electric heating tube 31 that is wound around the inside of the first mounting cavity 211 and the second mounting cavity 221. The electric heating tube 31 is electrically connected to the power supply 32. The power supply 32 can supply power to the electric heating tube 31 so that the electric heating tube 31 can heat the stirring shaft 21 and the stirring blade 22. At the same time, when the stirring shaft 21 rotates, it can drive the stirring blade 22 to rotate, so as to stir and heat the material at various positions in the vessel 1 and improve the uniformity of heating the material.

[0017] It should be noted that the stirring blades 22 include multiple rows of stirring shafts 21 arranged in a ring around the central axis of the stirring shaft 21. Each row of stirring shafts 21 includes multiple pieces of the outer wall of the stirring shaft 21 arranged at equal intervals along the central axis of the stirring shaft 21. At the same time, the heating tube 31 includes multiple segments. The same segment of the heating tube 31 is arranged in a serpentine manner inside the second mounting cavity 221 of the stirring blades 22 and the first mounting cavity 211 of the stirring shaft 21 in the same row. Adjacent segments of the heating tube 31 are connected end to end so that multiple segments of the heating tube 31 are connected to form a single heating tube 31.

[0018] In this embodiment, as Figure 2As shown, the top of the vessel body 1 is provided with a through hole 15. The upper end of the stirring shaft 21 is installed inside the through hole 15 through a bearing 23. At the same time, the stirring shaft 21 is connected to a drive mechanism for driving the stirring shaft 21 to rotate. In this embodiment, the drive mechanism includes a driven gear 24 coaxially mounted on the upper end of the stirring shaft 21. The driven gear 24 meshes with the driving gear 25. The driving gear 25 is connected to the output shaft of the motor 26. The motor 26 can drive the driving gear, and the driving gear 25 can drive the driven gear 24 to rotate, thereby driving the stirring shaft 21. For the drive mechanism, it only needs to meet the requirement of being able to drive the stirring shaft 21 to rotate. Therefore, it is not limited to a specific structure. For example, in some other embodiments, the drive mechanism includes a driven pulley coaxially mounted on the upper end of the stirring shaft 21. The driven pulley is connected to the driving pulley via a belt. The driving pulley is connected to the output shaft of the motor 26. The motor 26 can drive the driving pulley to rotate, and the driving pulley can drive the driven pulley to rotate via a belt, thereby driving the stirring shaft 21 to rotate.

[0019] In this embodiment, as Figure 4 As shown, the top of the stirring shaft 21 is an open structure and is provided with a first flange 212. The first flange 212 is an annular structure. Both ends of the heating element 31 extend from the inside of the stirring shaft 21 through the opening at the top of the stirring shaft 21 and are fitted with second flanges 311. The second flange 311 is a circular flat plate structure and is installed on the top of the first flange 212. By cooperating with the first flange 212 and the second flange 311, the heating element 31 can be fixedly installed inside the first mounting cavity 211 and the second mounting cavity 221. In this embodiment, a sealing ring 2121 is installed between the first flange 212 and the second flange 311. The sealing ring 2121 is either a silicone ring or a rubber ring. The sealing ring 2121 can prevent the hot air inside the first mounting cavity 211 and the second mounting cavity 221 from escaping between the first flange 212 and the second flange 311, thereby saving energy.

[0020] To prevent the wires between the heating element 31 and the power supply 32 from getting tangled or broken when the heating element 31 rotates, in this embodiment, the heating assembly 3 also includes a conductive slip ring 33. The rotor of the conductive slip ring 33 is connected to the top of the second flange 311, the wiring on the rotor of the conductive slip ring 33 is electrically connected to the wiring at both ends of the heating element 31, and the wiring on the stator of the conductive slip ring 33 is electrically connected to the power supply 32. The conductive slip ring 33 is fixedly installed on the top of the vessel body 1 by a mounting bracket.

[0021] Specific principle: During distillation, the material is added into the vessel body 1 through the feed port 12. The motor 26 drives the drive gear 25 to rotate, which in turn drives the driven gear 24 to rotate. The driven gear 24 drives the stirring shaft 21 to rotate, which in turn drives the stirring blades 22 to rotate. The stirring shaft 21 and the stirring blades 22 drive the heating element 21 to rotate. At the same time, the power supply 32 supplies power to the heating element 31 so that the heating element 31 can heat the stirring shaft 21 and the stirring blades 22. When the stirring shaft 21 and the stirring blades 22 rotate, they can stir and heat the material at various positions in the vessel body 1, improving the uniformity of heating. The heated and distilled material can be discharged from the vessel body 1 through the discharge port 13. At the same time, the material left in the vessel body 1 after distillation can be discharged from the vessel body 1 through the waste discharge port 14.

[0022] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
