Description

Technical Field

[0001] This utility model relates to the field of essential oil distillation towers, specifically to a multi-stage condensation reflux essential oil distillation tower. Background Technology

[0002] A multi-stage reflux condenser distillation column is a specialized device for extracting plant essential oils. It uses bottom heating to generate essential oil-containing vapors from the plant and water mixture. As the vapor rises, it is cooled and condensed through multiple condensation units. Part of the condensate is refluxed and re-contaminated with the vapor, increasing the essential oil concentration. Finally, the discharged mixture is separated to obtain pure essential oils. Compared to single-stage equipment, it reduces essential oil loss, increases extraction rate and purity, and is suitable for extracting essential oils from plants such as rose and peppermint, for use in fragrances, cosmetics, and other fields. In existing technical solutions, reflux control lacks precision. The reflux structure of existing devices is mostly passive reflux, which cannot flexibly adjust the reflux flow rate and reflux speed according to the distillation process. When the amount of steam in the distillation column fluctuates, it is easy to have problems such as excessive reflux flow leading to a decrease in distillation efficiency, or insufficient reflux flow affecting the concentration of essential oils. It is difficult to adapt to the distillation needs of different plant raw materials and reduce the versatility of the equipment. In order to solve this technical problem, this utility model proposes an essential oil distillation column with multi-stage condensation reflux. Utility Model Content

[0003] In existing technical solutions, reflux control lacks precision. The reflux structure of existing devices is mostly passive reflux, which cannot flexibly adjust the reflux flow rate and reflux speed according to the distillation process. When the amount of steam in the distillation column fluctuates, it is easy to have problems such as excessive reflux flow leading to a decrease in distillation efficiency, or insufficient reflux flow affecting the concentration of essential oils. It is difficult to adapt to the distillation needs of different plant raw materials and reduce the versatility of the equipment. In order to solve this technical problem, this utility model proposes an essential oil distillation column with multi-stage condensation reflux.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-stage condensation reflux essential oil distillation tower, including a distillation tower, wherein multiple partitions are fixedly connected inside the distillation tower, and multiple through pipes are fixedly connected inside each partition, a pair of inner plates are fixedly connected inside the top of the distillation tower, and each inner plate has a vent hole inside, and an exhaust pipe is fixedly connected to the top of the distillation tower.

[0005] Preferably, a feed pipe is fixedly connected to the outer wall of the distillation column, and a valve is fixedly connected to the outer wall at the end of the feed pipe.

[0006] Preferably, a discharge pipe is fixedly connected to the bottom of the distillation column, and a heating box is fixedly connected to the other end of the discharge pipe. A pair of electric heating rods are fixedly connected inside the heating box.

[0007] Preferably, a vent pipe is fixedly connected to the top of the heating box, and the other end of the vent pipe passes through the distillation column and extends into the distillation column.

[0008] Preferably, a cooling box is fixedly connected to the other end of the exhaust pipe, and an electric cooling rod is fixedly connected inside the cooling box.

[0009] Preferably, a sedimentation tank is provided below the cooling tank, a discharge pipe is fixedly connected to one side of the outer wall of the sedimentation tank, a valve three is fixedly connected to the outer wall of the discharge pipe, a reflux pipe is fixedly connected to the bottom of the sedimentation tank, a valve two is fixedly connected to the outer wall of the reflux pipe, and the other end of the valve two passes through the distillation column and extends into the distillation column.

[0010] This invention provides a multi-stage condensation and reflux essential oil distillation column. It offers the following advantages: The partitions within the distillation column hold the refined material, and a pipe allows steam to circulate. Raw materials are added via the feed pipe and valve one, while a portion of the raw material is directed into the heating chamber via the discharge pipe. Steam generated by the electric heating rod enters the distillation column through the vent pipe. The distilled steam enters the cooling chamber through the vent holes and exhaust pipe of the inner plate, where it is cooled into liquid by an electric cooling rod. Separation occurs in the sedimentation tank, with the upper essential oil being discharged via valve three on the discharge pipe, and the lower liquid being refluxed and re-distilled via valve two on the reflux pipe. This design solves the problems of low efficiency and low raw material utilization in traditional distillation, changes the situation of incomplete refining, achieves continuous distillation and recycling, and improves refining efficiency and essential oil yield.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Please see Figure 1-3 This utility model provides a technical solution: Example 1: A multi-stage reflux essential oil distillation column, comprising a distillation column 1, with multiple baffles 13 fixedly connected inside the distillation column 1, each baffle 13 having multiple through pipes 20 fixedly connected inside; a pair of inner plates 12 fixedly connected inside the top of the distillation column 1, each inner plate 12 having a vent hole 14 inside; an exhaust pipe 8 fixedly connected to the top of the distillation column 1; a feed pipe 2 fixedly connected to the outer wall of the distillation column 1, with a valve 3 fixedly connected to the outer wall at the end of the feed pipe 2; a discharge pipe 4 fixedly connected to the bottom of the distillation column 1, with a heating box 5 fixedly connected to the other end of the discharge pipe 4; and a valve 3 fixedly connected inside the heating box 5. A pair of electric heating rods 19 are provided. A vent pipe 7 is fixedly connected to the top of the heating box 5. The other end of the vent pipe 7 passes through the distillation column 1 and extends into the distillation column 1. The other end of the exhaust pipe 8 is fixedly connected to the cooling box 9. An electric cooling rod 18 is fixedly connected inside the cooling box 9. A sedimentation box 10 is provided below the cooling box 9. A discharge pipe 17 is fixedly connected to one side of the outer wall of the sedimentation box 10. A valve 16 is fixedly connected to the outer wall of the discharge pipe 17. A reflux pipe 11 is fixedly connected to the bottom of the sedimentation box 10. A valve 15 is fixedly connected to the outer wall of the reflux pipe 11. The other end of the valve 15 passes through the distillation column 1 and extends into the distillation column 1.

[0015] Open valve 1 (3) to allow the refined material to enter distillation column 1 through feed pipe 2 and accumulate on baffle 13. When the accumulation reaches the height of through pipe 20, the refined material will flow to the lower layer, gradually filling the bottom baffles 13. Some of it will also enter heating box 5 through discharge pipe 4. At this time, electric heating rod 19 is activated to heat the solution in heating box 5. The generated steam enters distillation column 1 through vent pipe 7 and then rises through through pipe 20 to distill the refined material on each baffle 13. Afterward, the steam enters exhaust pipe 8 through vent hole 14 of inner plate 12 and then enters cooling box 9. At the same time, electric cooling rod 18 is activated to cool the steam. The cooled liquid settles in sedimentation box 10. Open valve 3 (16) to discharge the upper essential oil through discharge pipe 17, while the lower liquid flows back to distillation column 1 through reflux pipe 11 by opening valve 2 (15) for re-distillation. The cooperation of these components improves working efficiency.

[0016] Working principle: Open valve 1 (3) to feed the refined material into the distillation tower 1 through feed pipe 2. The refined material ash accumulates on the baffles 13. When it accumulates to the height of the through pipe 20, it flows downward to the lower layer, gradually filling the bottom baffles 13. Part of it flows into the heating box 5 through the discharge pipe 4. At this time, the electric heating rod 19 is activated to heat the solution inside the heating box 5, causing the steam to flow into the distillation tower 1 through the vent pipe 7 and float upward through the through pipe 20, distilling each baffle 13. Finally, it floats to the exhaust pipe 8 through the vent hole 14 in the inner plate 12 and passes through the cooling box 9. At this time, the electric cooling rod 18 is activated to cool the steam. The cooled liquid precipitates through the sedimentation box 10. Open valve 3 (16) to discharge the upper essential oil through the discharge pipe 17, and the lower liquid flows back into the distillation tower 1 through the return pipe 11 by opening valve 2 (15) for re-distillation. Through their coordination, the working efficiency is improved.
