Abstract

The present invention relates to a supercritical device with a temperature control system applied in the field of supercritical extraction technology, comprising an extraction outer tank, an extraction inner tank, a telescopic unit, a movable plug, an electric heating column unit, a refrigeration unit, a cooling pipeline and a cooling subdivision tube.

Moreover, due to the reduction in the ratio of the extraction medium, the influence of the extraction medium on the temperature regulation of the extraction material is also reduced, thereby effectively improving the temperature control efficiency of the supercritical extraction equipment.

Description

Technical Field

[0001] The present invention relates to a supercritical device, in particular to a supercritical device with a temperature control system applied in the technical field of supercritical extraction. Background Art

[0002] Supercritical extraction is a technique that uses supercritical fluid as an extraction medium to separate the different components in a mixture. A supercritical fluid is a fluid state above its critical temperature and pressure. In this state, the fluid has unique solubility and diffusion properties, making it an effective medium in the extraction process. Supercritical extraction is the optimal method for extracting active ingredients in plants.

[0003] The specification of Chinese invention patent CN202120302110.9 discloses "An efficient high-pressure foaming device for supercritical fluids". By monitoring the temperature inside the reactor through a temperature monitoring device, when the temperature is lower than the set temperature, the heating plate inside the heating box is turned on, and by opening the electric valve outside the heating box, hot air is allowed to enter the temperature control box from the air inlet to heat the inside of the reactor. When the temperature is higher than the set temperature, the refrigeration plate inside the refrigeration box is turned on, and by opening the electric valve outside the refrigeration box, cold air is allowed to enter the temperature control box from the air inlet to cool the inside of the reactor. The specification of Chinese invention patent CN202122720420.5 discloses "A supercritical extraction device for rose essential oil". Through the setting of the guide cover, it can guide the fluid of suitable temperature to surround the extraction tank, so that the extraction tank and its internal substances can reach the expected temperature value, and can realize active temperature control operation.

[0004] Currently, there are two ways to perform temperature control on supercritical extraction equipment. One is to perform temperature control on the extraction medium input into the extraction tank and then input it into the tank body. The other is to perform temperature control directly on the inside of the tank body. However, both of these temperature control methods act directly on the extraction medium. The extraction medium needs to be temperature controlled first before the temperature control of the extraction material can be indirectly achieved. The entire control process is inefficient, and the activity of the extraction material is affected by temperature. Therefore, accurate temperature control of the extraction material is an important factor in maintaining extraction activity. Summary of the Invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing temperature control and adjustment methods all act directly on the extraction medium. The extraction medium needs to be temperature-controlled and adjusted first before the temperature control and adjustment of the extraction material can be indirectly achieved. The entire adjustment process is inefficient.

[0006] To solve the above problems, the present invention provides a supercritical fluid device with a temperature control system, comprising an extraction outer tank, an extraction inner tank being sheathed within the extraction outer tank, an upper opening and a lower opening being respectively formed at the top and bottom of the extraction inner tank, both of which are in communication with the interior of the extraction outer tank, a combined sealing cover being fixedly connected to the top of the extraction inner tank, a telescopic unit being fixedly connected to the bottom of the extraction outer tank, an output end of the telescopic unit extending from the lower opening into the interior of the extraction inner tank, and a movable plug being fixedly connected to the output end of the telescopic unit;

[0007] The interior of the extraction outer tank is fixedly connected with a heating module, which is composed of an electric heating column unit fixed to the top of the movable plug;

[0008] A cooling module is fixedly connected to the outside of the extraction outer tank. The cooling module consists of a refrigeration unit fixed on the outer frame of the extraction outer tank and a cooling pipeline connected to the refrigeration unit. A cooling subdivision pipe is fixedly connected to the top inner wall of the extraction inner tank. The cooling pipeline is fixedly passed through the combined cover and is connected to the cooling subdivision pipe.

[0009] In the above-mentioned supercritical equipment with a temperature control system, the ratio of the extraction material and the extraction medium inside the extraction inner tank is cyclically adjusted and changed through the lifting and lowering movement of the movable plug in the extraction inner tank, thereby effectively improving the mixing effect of the extraction material and the extraction medium. At the same time, when the movable plug rises to the maximum height, the total amount of extraction medium in the extraction inner tank is reduced to a minimum, which facilitates the heating module and the cooling module to adjust the temperature of the extraction environment more quickly, effectively improving the temperature control efficiency of the supercritical extraction equipment.

[0010] As a further improvement of the present application, an output pipeline and an input pipeline are fixedly connected to the top of the combined cover, the output pipeline is fixedly connected to the middle part of the extraction inner tank, and the input pipeline is connected to the upper half of the upper opening. The extraction medium enters and is discharged from the extraction inner tank through the output pipeline and the input pipeline. The output pipeline connected to the middle part of the extraction inner tank can better discharge the extraction medium containing the extraction components, and the new medium needs to enter from the upper opening, thereby effectively avoiding direct circulation of the two media and effectively improving the extraction effect.

[0011] As a further improvement of the present application, an inner tank opening connected to the interior of the extraction inner tank is opened in the middle of the combined cover, and a tank plug is inserted into the interior of the inner tank opening. The extraction material in the extraction inner tank can be directly put in and taken out through the inner tank opening, thereby effectively improving the replacement efficiency of the extraction material.

[0012] As a further improvement of the present application, a material hanging basket is placed inside the extraction inner tank, and a sling is fixedly connected between the bag mouth of the material hanging basket and the bottom of the tank plug. The sling is spirally arranged and made of spring steel wire. The extraction material is stuffed into the material hanging basket and directly placed into the extraction inner tank, thereby effectively improving the replacement efficiency of the extraction material.

[0013] As another improvement of the present application, a connecting sleeve is fixedly connected to the bottom of the material hanging basket, and the connecting sleeve is socketed with the electric heating column unit. The connecting sleeve is made of stainless steel wire. By socketing the connecting sleeve with the electric heating column unit, the material hanging basket containing the extraction material can be accurately combined with the electric heating column unit, thereby effectively improving the electric heating column unit for extracting the material.

[0014] As another improved supplement to the present application, a supporting vertical rod is fixedly connected to the middle part of the top of the connecting sleeve, and the top of the supporting vertical rod corresponds to the top bag opening of the material basket. The supporting vertical rod is used to provide support for the upper half of the material basket, thereby effectively improving the stability of the material basket when it rises, and at the same time effectively improving the connection effect between the sling and the material basket.

[0015] As another improved supplement to the present application, the middle and bottom inner walls of the extraction outer tank are fixedly connected with separation rings, and the two groups of separation rings are sealed and sleeved with the middle and bottom of the extraction inner tank respectively, and a connecting pipe is fixedly connected between the two groups of separation rings. The two groups of separation rings are used to isolate the middle area of ​​the extraction outer tank, and the top and bottom of the extraction outer tank are directly connected through the connecting pipe, thereby effectively reducing the total amount of extraction medium outside the extraction inner tank and effectively reducing the amount of extraction medium used.

[0016] As another improvement of the present application, the connecting tube is distributed in a ring shape with respect to the separating ring, and the connecting tube is movably connected to a separating plug inside. The top and bottom ends of the connecting tube are fixedly connected to the limiting ring, and the inner diameter of the limiting ring is smaller than the outer diameter of the separating plug. The separating plug is movable in the connecting tube to separate the top space and the bottom space of the extraction outer tank, so that the bottom of the extraction outer tank can be filled with other medium liquids that are easier to seal, further reducing the amount of extraction medium used, while effectively reducing the difficulty of sealing the bottom of the extraction outer tank, thereby effectively improving the sealing effect of the bottom of the extraction outer tank.

[0017] As another improved supplement to the present application, a liquid inlet pipe and a liquid discharge pipe are fixedly connected to the top and bottom of one end of the extraction outer tank respectively. The inner end of the liquid inlet pipe passes through the separation ring and extends to the bottom of the extraction outer tank. The injection and discharge of the filling liquid at the bottom of the extraction outer tank are realized through the liquid inlet pipe and the liquid discharge pipe, thereby effectively improving the control of the filling solution at the bottom of the extraction outer tank.

[0018] As another improvement supplement to the present application, a capacity cylinder is fixedly connected to the bottom of the other end of the extraction outer tank, and a capacity plug is movably connected to the inside of the capacity cylinder. By adjusting the position of the capacity plug in the capacity cylinder, the purpose of adjusting the volume of the bottom of the extraction outer tank is achieved, thereby effectively increasing the variation range of the volume at the top of the extraction outer tank, and effectively improving the ratio adjustment of the extraction medium at the top of the extraction outer tank and the inside of the extraction inner tank.

[0019] In summary, the present invention cyclically adjusts and changes the ratio of the extraction material and the extraction medium inside the extraction inner tank through the lifting and lowering movement of the movable plug in the extraction inner tank, so as to achieve the effect of repeatedly filling the extraction medium into the extraction inner tank and mixing with the extraction material, thereby effectively improving the mixing effect of the extraction material and the extraction medium and the extraction effect of the material components. When it is necessary to temperature-control the internal environment of the extraction equipment, the movable plug is first raised to squeeze part of the extraction medium in the extraction inner tank out of the extraction inner tank, so that the total amount of extraction medium in the extraction inner tank is reduced to a minimum. Then, the heating module and the cooling module are used to heat and cool the extraction material and the remaining extraction medium inside the extraction inner tank. At this time, the proportion of the extraction material in the extraction inner tank is larger, so the temperature of the extraction material can be more directly adjusted. Moreover, due to the reduction in the proportion of the extraction medium, the influence of the extraction medium on the temperature regulation of the extraction material is also reduced, thereby effectively improving the temperature control efficiency of the supercritical extraction equipment and realizing the rapid return of the temperature of the extraction material to a temperature suitable for the activity of the extraction substance.

[0031] The following describes three implementation methods of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figures 1 to 6 FIG1 shows a supercritical device with a temperature control system, comprising an extraction outer tank 1, an extraction inner tank 101 is sleeved inside the extraction outer tank 1, an upper opening 102 and a lower opening 103 are respectively opened at the top and bottom of the extraction inner tank 101, the upper opening 102 and the lower opening 103 are both connected to the interior of the extraction outer tank 1, a top end of the extraction inner tank 101 is fixedly connected to a combined cover 104, the combined cover 104 is plugged into the top end of the extraction outer tank 1, a bottom end of the extraction outer tank 1 is fixedly connected to a telescopic unit 105, an output end of the telescopic unit 105 extends from the lower opening 103 into the interior of the extraction inner tank 101, and the telescopic unit 105 is fixedly connected to the bottom end of the extraction outer tank 1. The output end is fixedly connected to a movable plug 106, and the top of the combined cover 104 is fixedly connected to an output pipeline 107 and an input pipeline 108. The output pipeline 107 is fixedly connected to the middle of the extraction inner tank 101, and the input pipeline 108 is connected to the upper half of the upper opening 102. The extraction medium enters and exits the extraction inner tank 101 through the output pipeline 107 and the input pipeline 108. The output pipeline 107 connected to the middle of the extraction inner tank 101 can better discharge the extraction medium containing the extraction components, while the new medium needs to enter from the upper opening 102, thereby effectively avoiding direct circulation of the two media and effectively improving the extraction effect;

[0034] During supercritical extraction, the extraction material is stored in the extraction inner tank 101, and the extraction medium in the extraction outer tank 1 enters the extraction inner tank 101 through the upper port 102 to mix with the extraction material. When the movable plug 106 moves upward in the extraction inner tank 101, the space at the top of the extraction inner tank 101 is reduced. Since the extraction material will not be discharged from the extraction inner tank 101, what is squeezed out from the extraction inner tank 101 is the extraction medium. Then the movable plug 106 moves downward again in the extraction inner tank 101, and the space at the top of the extraction inner tank 101 is restored. The extraction medium that was squeezed out before returns to the extraction inner tank 101 to mix with the extraction material, so that the extraction medium is repeatedly filled into the extraction inner tank 101 and mixed with the extraction material. The effect of material mixing is achieved, thereby effectively improving the mixing effect of the extraction material and the extraction medium and the extraction effect of the material components. When the extraction medium needs to be replaced, the movable plug 106 still moves upward, and at this time, the output pipeline 107 connected to the middle of the extraction inner tank 101 is opened, and the input pipeline 108 at the top of the extraction inner tank 101 is also opened. In the process of the extraction medium being squeezed out, part of the extraction medium is discharged from the output pipeline 107, and another part of the new extraction medium is sent into the input pipeline 108 to make up for it, so as to meet the pressure balance of the extraction medium. When the movable plug 106 is subsequently lowered again, the output pipeline 107 and the input pipeline 108 are both closed, and the extraction medium is repeatedly sucked back into the extraction inner tank 101.

[0035] Figures 2 to 6 As shown, a heating module 2 is fixedly connected to the interior of the extraction outer tank 1. The heating module 2 is composed of an electric heating column unit 2 fixed to the top of the movable plug 106. A cooling module 3 is fixedly connected to the exterior of the extraction outer tank 1. The cooling module 3 is composed of a refrigeration unit 301 fixed to the outer frame of the extraction outer tank 1 and a cooling pipe 302 connected to the refrigeration unit 301. A cooling subdividing pipe 303 is fixedly connected to the inner wall of the top of the extraction inner tank 101. The cooling pipe 302 is fixedly passed through the combined cover 104 and communicates with the cooling subdividing pipe 303.

[0036] When the temperature of the internal environment of the extraction equipment is controlled, the specific extraction material is at the edge value of its own active temperature range, and the temperature of the extraction material needs to be restored to the middle value. The main control object is the extraction material, and the movable plug 106 still moves upward to squeeze the extraction medium in the extraction inner tank 101 outward to reduce the proportion of the extraction material in the extraction inner tank 101. Then, the heating module and the cooling module are used to heat up and cool the extraction material and the remaining extraction medium in the extraction inner tank 101, that is, the electric heating column unit 2 electrically heats the inside of the extraction inner tank 101, and the cooling pipeline 302 cooperates with the cooling subdivision pipe 303 to perform heat transfer and cooling on the inside of the extraction inner tank 101, so that the extraction material is restored to a temperature that meets the activity of the extraction substance. At this time, the extraction The material accounts for a larger proportion in the extraction inner tank 101, so the extraction material can be heated and cooled more directly, and due to the reduction in the proportion of the extraction medium, the influence of the extraction medium on the temperature regulation of the extraction material is also reduced, effectively improving the temperature control efficiency of the supercritical extraction equipment, and realizing the rapid recovery of the extraction material to the most suitable temperature for its own activity, so as to better protect the activity of the extraction material itself. Subsequently, the movable plug 106 is slowly lowered and restored, so that the previously squeezed extraction medium is slowly returned to the inside of the extraction inner tank 101, and the temperature of the extraction medium is gradually and stably regulated. For the subsequent extraction medium to be input, the existing medium temperature control method is used to pre-heat and cool it, thereby reducing the impact of the newly input extraction medium on the rapid temperature control of the extraction material.

[0037] Second implementation method:

[0038] Compared with the first embodiment, the main new addition is a material hanging basket 402. The specific new structure is as follows: the regional structure is consistent with the first embodiment.

[0039] Figures 3 to 5 and Figures 7 and 8As shown, the middle part of the combined cover 104 is provided with an inner tank port 4 connected to the interior of the extraction inner tank 101, and a tank plug 401 is inserted into the inner tank port 4. The extraction material in the extraction inner tank 101 is directly put in and taken out through the inner tank port 4, which effectively improves the replacement efficiency of the extraction material. A material hanging basket 402 is placed inside the extraction inner tank 101, and a sling 403 is fixedly connected between the bag mouth of the material hanging basket 402 and the bottom of the tank plug 401. The sling 403 is spirally arranged and made of spring steel wire. The extraction material is stuffed into the material hanging basket 402 and directly placed into the extraction inner tank 101, thereby effectively improving the replacement efficiency of the extraction material. The bottom of the material hanging basket 402 is fixedly connected A connecting sleeve 404 is connected, and the connecting sleeve 404 is sleeved with the electric heating column unit 2. The connecting sleeve 404 is made of stainless steel wire material. By sleeve-fitting the connecting sleeve 404 with the electric heating column unit 2, the material hanging basket 402 containing the extraction material is accurately combined with the electric heating column unit 2, thereby effectively improving the electric heating column unit 2 for extracting the material. A supporting vertical rod 405 is fixedly connected to the middle of the top of the connecting sleeve 404. The top of the supporting vertical rod 405 is sleeved and corresponds to the top bag opening of the material hanging basket 402. The supporting vertical rod 405 is used to provide support for the upper half of the material hanging basket 402, effectively improving the stability of the material hanging basket 402 when it rises, and at the same time effectively improving the connection effect between the sling 403 and the material hanging basket 402;

[0040] When the extraction material is stored in the extraction inner tank 101, the extraction material is placed in the material basket 402, and the material basket 402 containing the extraction material is directly placed into the extraction inner tank 101 from the inner tank mouth 4, and then the inner tank mouth 4 is sealed with the tank plug 401. In the process of placing the material basket 402 into the extraction inner tank 101, the connecting sleeve 404 at the bottom of the material basket 402 is connected with the electric heating column unit 2, so that the material basket 402 is accurately placed in the middle of the movable plug 106, and when the extraction material is heated, the electric heating column unit 2 effectively improves the uniform heating effect of the extraction material in the material basket 402, and when the material basket 402 rises with the movable plug 106, the material basket 402 can be in the center position of the cooling subdivision tube 303, thereby effectively improving the uniform cooling effect of the cooling subdivision tube 303 on the extraction material.

[0041] The third implementation method:

[0042] Compared with the first embodiment, the main feature is the addition of a separation ring 5 . The specific structure of the new structure is as follows. The remaining structures are the same as those of the first embodiment.

[0043] Figure 3 and Figure 9As shown, spacer rings 5 ​​are fixedly connected to the inner wall of the middle and bottom of the extraction outer tank 1. Two sets of spacer rings 5 ​​are sealed and sleeved with the middle and bottom of the extraction inner tank 101 respectively. A connecting pipe 501 is fixedly connected between the two sets of spacer rings 5. The two sets of spacer rings 5 ​​are used to isolate the middle area of ​​the extraction outer tank 1, and the top and bottom of the extraction outer tank 1 are directly connected through the connecting pipe 501, thereby effectively reducing the total amount of extraction medium outside the extraction inner tank 101 and effectively reducing the amount of extraction medium used.

[0044] When the outer extraction tank 1 and the inner extraction tank 101 are assembled together, the middle and bottom of the inner extraction tank 101 are sealed with two sets of separation rings 5 ​​respectively, thereby isolating the middle area of ​​the outer extraction tank 1 and directly connecting the top and bottom of the outer extraction tank 1 through the connecting pipe 501. That is, the middle area of ​​the inner extraction tank 101 does not need to be filled with extraction medium, thereby effectively reducing the total filling amount of extraction medium, that is, the amount of extraction medium used.

[0045] Figure 3 and Figure 9 As shown, the connecting pipe 501 is distributed in an annular manner with respect to the separation ring 5, and the connecting pipe 501 is movably connected to the interior of the connecting pipe 501 with a separation plug 502. The top and bottom ends of the connecting pipe 501 are fixedly connected to the limiting ring 503. The inner diameter of the limiting ring 503 is smaller than the outer diameter of the separation plug 502. The separation plug 502 is movable in the connecting pipe 501 to separate the top space and the bottom space of the extraction outer tank 1, so that the bottom of the extraction outer tank 1 can be filled with other medium liquids that are easier to seal, further reducing the amount of extraction medium, while effectively reducing the sealing difficulty of the bottom of the extraction outer tank 1, thereby effectively improving the sealing effect of the bottom of the extraction outer tank 1. The top and bottom of one end of the extraction outer tank 1 are respectively fixedly connected with a liquid inlet pipe 504 and a liquid discharge pipe 505. The inner end of the liquid inlet pipe 504 passes through the separation ring 5 and extends to the bottom of the extraction outer tank 1. The filling liquid at the bottom of the extraction outer tank 1 is injected and discharged through the liquid inlet pipe 504 and the discharge pipe 505, effectively improving the control of the filling solution at the bottom of the extraction outer tank 1.

[0046] By moving the partition plug 502 in the connecting tube 501, the top space and the bottom space of the extraction outer tank 1 are separated. The bottom space of the extraction outer tank 1 no longer needs to be filled with the extraction medium. A medium solution that is easier to seal can be selected. The most common filling liquid is water. The bottom space of the extraction outer tank 1 is filled with water, thereby effectively reducing the use of the extraction medium.

[0047] Figure 1 and Figure 9As shown, a volumetric cylinder 506 is fixedly connected to the bottom of the other end of the extraction outer tank 1, and a volumetric plug 507 is movably connected to the interior of the volumetric cylinder 506. By adjusting the position of the volumetric plug 507 within the volumetric cylinder 506, the purpose of adjusting the volume of the bottom of the extraction outer tank 1 is achieved, thereby effectively increasing the range of variation of the volume at the top of the extraction outer tank 1, and effectively improving the adjustment of the ratio of the extraction medium at the top of the extraction outer tank 1 and the interior of the extraction inner tank 101;

[0048] When adjusting the amount of extraction medium used, that is, when the top of the extraction outer tank 1 requires more extraction medium and the top of the extraction outer tank 1 requires less extraction medium, the capacity plug 507 is synchronously controlled to make corresponding position adjustments in the capacity cylinder 506, so as to achieve the effect of indirectly giving up and occupying the space at the top of the extraction outer tank 1 by adjusting the volume of the bottom of the extraction outer tank 1.

[0049] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
