Abstract
Description
Technical Field
[0001] This utility model relates to the field of osmanthus component extraction technology, specifically a supercritical carbon dioxide extraction device for osmanthus components. Background Technology
[0002] Supercritical CO2 fluid extraction utilizes the relationship between the solubility of a supercritical fluid and its density, that is, a chemical reaction that takes advantage of the influence of pressure and temperature on the solubility of a supercritical fluid. By reducing pressure and increasing temperature, the supercritical fluid is turned into a normal gas, and the extracted substance is completely or substantially precipitated out, thereby achieving the purpose of separation and purification.
[0003] In the prior art, in order to ensure that the raw materials such as osmanthus, chrysanthemum, and licorice root are not affected by temperature during the extraction and processing, a device has been developed that can perform supercritical carbon dioxide extraction on the components of such raw materials by heating in a water bath. However, carbon dioxide is a gas and is easily blocked by substances during its flow. In particular, small raw materials such as osmanthus tend to accumulate and affect the flow of air. The accumulation can also prevent the surface of the raw materials from making sufficient contact with carbon dioxide, resulting in insufficient extraction and waste of raw materials. Based on this, this application provides a supercritical carbon dioxide extraction device for osmanthus components to solve the above problems. Utility Model Content

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1 to 4This utility model provides a technical solution: a supercritical carbon dioxide extraction device for osmanthus components, including a main tank 1, an extraction tank 2 fixed between the front and rear inner walls of the main tank 1, two water inlet pipes 3 passing through and fixed to the left side of the main tank 1, an air inlet pipe 4 fixed to the bottom of the extraction tank 2 with its end passing through and fixedly connected to the outside of the main tank 1, an outlet pipe 5 fixed to the top of the extraction tank 2 with its top end passing through the top of the main tank 1, a flow pipe 6 passing through and fixed to the right side of the main tank 1, a dispersing component 700 for turning over osmanthus flowers installed on the inner side of the extraction tank 2, and a placement plate 8 fixed to the inner side of the extraction tank 2, with several air distribution holes 9 opened on the top of the placement plate 8. Through the coordinated use of the extraction tank 2, water inlet pipe 3, air inlet pipe 4, discharge pipe 5, flow pipe 6, and dispersing component 700 inside the main tank 1, the osmanthus flowers can be extracted more effectively. The turning action can fully disperse the accumulated osmanthus flowers, and the openings allow carbon dioxide to pass through smoothly, so that the surface of the osmanthus flowers can fully contact the carbon dioxide and be fully and effectively extracted. In addition, the internal structure restricts the osmanthus flowers to be close to the dispersing component 700, improving the actual use effect of the dispersing component 700, so that the osmanthus flowers can be fully turned, making the extraction work efficient.
[0026] In this embodiment, the dispersing component 700 is a structure used to turn over the piled osmanthus flowers so that they can be dispersed.
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the dispersing assembly 700 includes two drive shafts 701 rotatably connected to the rear side wall of the extraction tank 2 via bearings. A hollow roller 702 is fixed to the outside of the drive shaft 701, and several arc-shaped baffles 703 arranged in a circle are fixed to the outside of the hollow roller 702. A power source capable of driving the two drive shafts 701 to rotate is installed on the back of the main tank 1.
[0028] It should be noted that the power source includes a gear 704 fixed to the outside of the drive shaft 701, a support box 705 fixed to the back of the main body barrel 1, a support frame 706 fixedly installed on the inner bottom wall of the support box 705, a servo motor 707 fixedly installed on the top of the support frame 706, one end of the back of the drive shaft 701 passes through the back of the extraction barrel 2 and the main body barrel 1 and extends into the interior of the support box 705, the output shaft of the servo motor 707 is fixedly connected to one end of the back of any drive shaft 701, and the two gears 704 mesh with each other, so that the servo motor 707 can drive the corresponding drive shaft 701 to rotate, and the rotation of the two drive shafts 701 is realized under the meshing transmission of the gears 704, thus completing the power transmission effect.
[0029] In addition, the outer side of the arc-shaped deflector 703 is provided with evenly distributed ventilation holes 708, which allow supercritical carbon dioxide to pass through normally. The arc-shaped deflectors 703 on the left and right sides are symmetrically distributed. The symmetrically distributed arc-shaped deflectors 703 allow the osmanthus flowers to be turned over by the concave side when the two sides rotate in opposite directions, thus improving the effect of turning and dispersing.
[0030] It should also be noted that a limiting mesh plate 10 is fixed on the inner side of the extraction tank 2 above the arc-shaped lever 703, a central protrusion 11 is fixed at the top center of the placement plate 8, and limiting blocks 12 are fixed between the left and right inner side walls of the extraction tank 2 and the top of the placement plate 8. The air distribution holes 9 are located on the left and right sides of the central protrusion 11. The opposite sides of the two limiting blocks 12 are both inclined, so that the osmanthus flowers piled on the placement plate 8 can be limited by the limiting blocks 12 and the central protrusion 11, thus facilitating the movement of the arc-shaped lever 703.
[0031] Meanwhile, an air guide frame 13 is fixed on the inner side of the extraction tank 2 above the limiting mesh plate 10. The air guide frame 13 is frustum-shaped and the inner diameter of the top is smaller than the inner diameter of the bottom. The interior of the discharge pipe 5 is connected to the interior of the air guide frame 13, so that the gas inside the air guide frame 13 can be discharged normally through the discharge pipe 5. An annular sealing plate 14 is fixed between the outer side of the extraction tank 2 and the inner side of the main tank 1. Two water inlet pipes 3 are arranged longitudinally. An extraction space is formed between the placement plate 8 and the limiting mesh plate 10. The flow pipe 6 is located between the top of the extraction space and the bottom of the annular sealing plate 14, so that the water inlet pipe 3 can normally pass hot water in and wrap the extraction space. The flow pipe 6 located at the top of the extraction space can normally discharge hot water.
[0032] like Figure 4 As shown, a temperature sensor 15 is fixedly installed on the inner side of the main tank 1 to monitor the water temperature, facilitating judgment by external personnel. Two support rods 16 are fixed between the bottom of the extraction tank 2 and the inner bottom wall of the main tank 1 to improve the installation stability of the extraction tank 2. A drain pipe 17 connected to the interior of the main tank 1 is fixedly installed at the bottom of the main tank 1. A control valve 18 connected to the interior of the main tank 1 is fixedly installed on the drain pipe 17. By opening the control valve 18, the water inside the main tank 1 can be discharged through the drain pipe 17. A sealing door 19 is hinged to the front of the main tank 1. A communication port connected to the interior of the extraction space and allowing the sealing door 19 to be closed is opened between the front of the main tank 1 and the extraction tank 2. The osmanthus raw material can be placed or taken out through the communication port. Closing the sealing door 19 can close the communication port to achieve a relatively closed state. A main control panel 20 is fixedly installed on the front of the main tank 1 for general control.
[0033] It can also be explained that a support plate can be fixed between the left and right inner walls of the extraction tank 2, and the back side of the support plate is rotatably connected to the front end of the drive shaft 701 through a bearing, which plays an auxiliary support role for the drive shaft 701, enabling it to rotate more stably.
[0034] The working principle of the above embodiments is as follows:
[0035] During the supercritical carbon dioxide extraction of osmanthus, the sealing door 19 is opened and the raw material is placed on the placement plate 8. Hot water is introduced through two water inlet pipes 3, allowing the hot water to fill the outside of the extraction tank 2 and enclose the space between the limiting mesh plate 10 and the opposite side of the placement plate 8. The flow pipe 6 helps to drain the upper layer of hot water. The continuous introduction and drainage of hot water achieves stable water bath heating. High-pressure supercritical carbon dioxide gas is introduced through the air inlet pipe 4. After being diverted through the gas distribution hole 9, the gas enters the space at the top of the placement plate 8 and contacts the osmanthus raw material. The servo motor 707 is started to drive the corresponding main... The rotating shaft 701, under the meshing transmission of the two gears 704, causes both drive shafts 701 to start rotating, driving the hollow roller 702 to rotate. This allows the arc-shaped deflector 703 to move the accumulated osmanthus flowers, increasing the actual contact area between the osmanthus flowers and supercritical carbon dioxide gas, thus facilitating efficient dissolution and extraction. The vent 708 allows the gas to pass through smoothly, while the osmanthus components dissolved in carbon dioxide continue to rise with the carbon dioxide. After passing through the limiting mesh plate 10, they enter the discharge pipe 5 for collection under the action of the gas guide frame 13, completing the extraction of osmanthus components.
[0036] Compared with existing technologies, this supercritical carbon dioxide extraction device for osmanthus components, through the coordinated use of the extraction tank 2, water inlet pipe 3, air inlet pipe 4, discharge pipe 5, flow pipe 6, and dispersing component 700 inside the main tank 1, can more effectively extract osmanthus. The agitation action thoroughly disperses the accumulated osmanthus flowers, and the openings allow carbon dioxide to pass through smoothly, ensuring full contact between the osmanthus flower surface and the carbon dioxide for effective extraction. Furthermore, the internal structure helps the osmanthus flowers approach the dispersing component 700, improving its effectiveness and allowing for efficient agitation. This solves the problem of insufficient extraction and material waste that often occurs in existing supercritical carbon dioxide extraction devices when extracting easily clump-forming materials like osmanthus.
