Description

Technical Field

[0001] This utility model relates to the field of distillation technology, and in particular to an oil distillation extraction device. Background Technology

[0002] Oil distillation is a commonly used oil purification technology, widely applied in chemical, pharmaceutical, and food industries. The core principle of this technology is based on the difference in boiling points of substances, using heating and condensation to separate and purify oil mixtures. In the oil distillation process, the oil mixture is first heated to boiling, generating steam. Because different components have different boiling points, the content of each component in the steam will also vary. This steam, after being cooled by a condenser, will re-condense into liquid; the collected liquid is the purified oil component. Specifically, oil distillation can be subdivided into several methods, such as vacuum gas distillation and short-path molecular distillation. Vacuum gas distillation uses dry steam under vacuum conditions to remove odorous substances and low-molecular-weight harmful components from oils, achieving deodorization and purification. Short-path molecular distillation is more suitable for separating oil components with different relative molecular masses. By controlling the distillation temperature and pressure, volatile components are completely evaporated, thus achieving oil purification. Furthermore, oil distillation can be combined with other technologies, such as solvent extraction and supercritical fluid extraction, to improve extraction efficiency and purity. Solvent extraction uses organic solvents to extract certain components from oils and fats, while supercritical fluid extraction uses fluids in a supercritical state to dissolve and separate oil and fat components. In general, oil distillation is a highly efficient and environmentally friendly oil purification technology with broad application prospects.

[0003] The existing patent application CN202322850977.X proposes an oil thin-film distillation device. Although it has multiple evenly distributed heat-conducting plates fixed through the outer wall of the conduit corresponding to the condenser tube, which can improve the heat conduction and condensation effect and further improve the distillation effect, the steam in the center of the conduit is farther away from the conduit wall and heat-conducting plates than the steam near the conduit wall and heat-conducting plates. Therefore, the cooling and condensation rate is slower, resulting in a slower overall condensation rate of the steam and thus a lower efficiency of oil distillation and extraction. Therefore, it needs to be improved. Utility Model Content

[0004] The main objective of this invention is to provide an oil distillation and extraction device that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An oil distillation extraction apparatus includes a distillation kettle and an oil-water separator. A cooling pipe connects the distillation kettle and the oil-water separator. A condensation assembly is fixedly installed inside the cooling pipe. The condensation assembly consists of a multi-faceted heat exchange tube, a multi-faceted connecting pipe, and an installation connecting pipe. There are two multi-faceted connecting pipes, which are respectively installed at both ends of the multi-faceted heat exchange tube. There are two installation connecting pipes, which are respectively installed at one end of the two multi-faceted connecting pipes.

[0007] Preferably, the cooling pipe consists of a cooling pipe body, an inlet pipe, and an outlet pipe, with both the inlet and outlet pipes fixedly installed on the cooling pipe body.

[0008] Preferably, two mounting holes are symmetrically opened on both sides of the cooling pipe body, and the mounting holes penetrate through the inside and outside of the cooling pipe body.

[0009] Preferably, the multi-faceted connecting pipe and the mounting connecting pipe on the condensing assembly are both located inside the cooling pipe body on the cooling pipe, and the two mounting connecting pipes on the condensing assembly are respectively fixedly inserted into two mounting through holes opened on the two side walls of the cooling pipe body.

[0010] Preferably, the multi-faceted heat exchange tube and the two multi-faceted connecting tubes on the condensation assembly are fixedly connected, and the multi-faceted connecting tubes are fixedly connected to the mounting connecting tubes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By installing a condensation assembly consisting of multi-faceted heat exchange tubes, multi-faceted connecting tubes, and installation connecting pipes inside the cooling pipes, the steam can approach the wall of the condensation assembly when it enters the condensation assembly, thereby more effectively exchanging heat with the cooling liquid flowing through the cooling pipes. This allows the steam to cool down and condense quickly, ultimately improving the efficiency of oil distillation extraction. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an oil distillation extraction device includes a distillation kettle 1 and an oil-water separator 3. A cooling pipe 2 connects the distillation kettle 1 and the oil-water separator 3. A condensing assembly 4 is fixedly installed inside the cooling pipe 2. The condensing assembly 4 consists of a multi-faceted heat exchange tube 11, a multi-faceted connecting pipe 12, and an installation connecting pipe 13. There are two multi-faceted connecting pipes 12, which are respectively installed at both ends of the multi-faceted heat exchange tube 11. There are two installation connecting pipes 13, which are respectively installed at one end of the two multi-faceted connecting pipes 12. During oil distillation extraction, the oil mixture can be put into the distillation kettle 1, and then the distillation kettle 1 is started to heat the oil mixture to boiling, thereby generating steam. Then the steam will enter the condensing assembly 4. At this time, cooling water can be injected into the cooling pipe 2, so that the cooling water and the steam in the condensing assembly 4 can exchange heat, thereby rapidly cooling and condensing the steam in the condensing assembly 4. Finally, the condensed liquid will enter the oil-water separator 3, thereby using the oil-water separator 3 to separate the oil and water in the condensed liquid, thus completing the oil distillation extraction.

[0021] Therefore, by installing a condensing assembly 4 consisting of a multi-faceted heat exchange tube 11, a multi-faceted connecting tube 12, and an installation connecting tube 13 inside the cooling pipe 2, the steam can approach the wall of the condensing assembly 4 when it enters the condensing assembly 4, thereby more effectively exchanging heat with the cooling liquid flowing through the cooling pipe 2, which in turn enables the steam to cool down and condense quickly, ultimately improving the efficiency of oil distillation extraction.

[0022] Specifically, the cooling pipe 2 consists of a cooling pipe body 7, an inlet pipe 8, and an outlet pipe 9. The inlet pipe 8 and the outlet pipe 9 are both fixedly installed on the cooling pipe body 7. Two mounting holes 10 are symmetrically opened on both sides of the cooling pipe body 7, and the mounting holes 10 penetrate the inside and outside of the wall of the cooling pipe body 7. In use, the inlet pipe 8 and the outlet pipe 9 on the cooling pipe 2 can be connected to the cooling water circulation equipment. During the oil distillation and extraction process, the cooling water circulation equipment will send cooling water into the cooling pipe body 7 through the inlet pipe 8. At this time, the cooling water in the cooling pipe body 7 will fully contact the multi-faceted heat exchange pipe 11, the multi-faceted connecting pipe 12, and the mounting connecting pipe 13 on the condenser assembly 4. After the heat exchange is completed, the cooling water will flow back into the cooling water circulation equipment from the outlet pipe 9.

[0023] Furthermore, the multi-faceted connecting pipe 12 and the mounting connecting pipe 13 on the condenser assembly 4 are both located inside the cooling pipe body 7 on the cooling pipe 2. The two mounting connecting pipes 13 on the condenser assembly 4 are respectively fixedly inserted into two mounting through holes 10 opened on both sides of the cooling pipe body 7. The multi-faceted heat exchange pipe 11 and the two multi-faceted connecting pipes 12 on the condenser assembly 4 are fixedly connected, and the multi-faceted connecting pipe 12 and the mounting connecting pipe 13 are fixedly connected. A first conveying pipe 5 is fixedly installed on one of the mounting connecting pipes 13 on the condenser assembly 4, and the first conveying pipe 5 is fixedly connected to the distillation kettle 1. The other... A second conveying pipe 6 is fixedly installed on an installation connecting pipe 13, and the second conveying pipe 6 is also fixedly connected to the oil-water separator 3. During the oil distillation and extraction process, the steam in the distillation kettle 1 will enter the multi-faceted heat exchange pipe 11, multi-faceted connecting pipe 12 and installation connecting pipe 13 on the condensing assembly 4 through the first conveying pipe 5. When the steam completes heat exchange with the cooling water flowing through the cooling pipe body 7 through the multi-faceted heat exchange pipe 11, multi-faceted connecting pipe 12 and installation connecting pipe 13 on the condensing assembly 4, and then condenses into liquid, the condensed liquid will flow into the oil-water separator 3 through the second conveying pipe 6.
