Description

Technical Field

[0001] The present invention belongs to the technical field of extraction devices, specifically an extraction device for preparing medical external application gels. Background Art

[0002] Medical external application gels are a type of topical pharmaceutical preparation with specific therapeutic functions, usually applied to the skin surface in the form of gels. Their main components include drug active ingredients, gel matrices, and excipients, and they can provide therapeutic effects through local action. External application gels have certain adhesiveness, permeability, and controlled release properties, and can continuously release drug components onto the skin, providing slow and effective treatment. Honeysuckle is a plant commonly used in traditional Chinese medicine, mainly used for clearing heat and detoxifying, anti-inflammatory and antibacterial treatments, etc. Honeysuckle extracts usually contain several main components such as chlorogenic acid, flavonoid compounds, phenylethanol, volatile oils, saponins, and organic acids. Among them, volatile oils have antibacterial, soothing, and cooling effects, and the components in the volatile oils help relieve skin irritation and inflammation, and have a certain analgesic effect, and can be used as raw materials for preparing medical external application gels. Volatile oils are usually extracted by steam distillation, and this method can effectively extract volatile oil components from plants.

[0003] The invention patent with the publication number CN111974019B discloses an extraction device for shampoo production, which involves an extraction device for shampoo production. The key points of its technical solution are: including a distillation box and a control panel. An arc-shaped breathable plate is assembled inside the distillation box, and a first solenoid valve is assembled on the discharge pipe. The arc-shaped breathable plate divides the distillation box into a water storage chamber and a placement chamber. A water storage tank is provided at the bottom of the water storage chamber, and a gas storage tank is connected to the upper side of the water storage tank by a pipeline. A number of impact plates are evenly arranged annularly on the hollow rotating shaft. There are two circumferentially separate high-pressure air valves on the rotating box. A number of hollow stirring rods matching the arc surface of the arc-shaped breathable plate are assembled on the four sides of the cross-shaped hollow pipe.

Detailed implementation manner

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0031] Example 1: As Figures 1 to 7 shown, the medical external application gel preparation extraction device described in the embodiment of the present invention includes an extraction tank 1, a condensation tank 4, a collection tank 5 and a steam generator 6;

[0032] The top of the extraction tank 1 is connected to the condensation tank 4 through a connecting pipe 3. The bottom of the condensation tank 4 is connected to a collection tank 5. The air outlet end of the steam generator 6 is connected to a steam duct 12. The steam duct 12 extends into the extraction tank 1. An electromagnetic valve is installed on the steam duct 12;

[0033] A through groove is opened in the middle of the extraction tank 1. A movable frame 2 in the shape of a Chinese character "ri" is slidably arranged in the through groove. Mounting frames 7 are respectively fixed inside both sides of the movable frame 2. A support plate 8 is rotatably connected to the middle of the mounting frame 7 through a mounting shaft 25. A circular hole is opened in the middle of the support plate 8. Screens 10 are respectively fixed on the front and back sides of the circular hole. First magnetic blocks 9 are arranged on the mounting frames 7. There are multiple first magnetic blocks 9 and they are symmetrically inlaid on both sides of the mounting frames 7;

[0034] It further includes a limiting component. The limiting component includes fixing plates 24 symmetrically arranged inside both sides of the mounting frame 7. There are two fixing plates 24 on each side. Clamping plates 26 are respectively fixed on the opposite side walls of the two fixing plates 24 through first springs. The clamping plates 26 clamp on both sides of the mounting shaft 25; The mounting shaft 25 is inserted into the middle of the two clamping plates 26 from the vertical grooves on the inner wall of the mounting frame 7;

[0035] During operation, when it is necessary to extract the volatile oil contained in honeysuckle through steam distillation, first, the two ends of the support plate 8 are adsorbed by the magnet block 9 to limit the support plate 8, so that the support plate 8 and the screen 10 are in a horizontal state. Then, the honeysuckle can be stacked on the top of the screen 10, and the mounting shaft 25 can move up and down between the two clamping plates 26. Under the influence of its own weight, the support plate 8 and the mounting shaft 25 are displaced to the lowest position of the mounting frame 7. At this time, the honeysuckle on the screen 10 is below the upper end surface of the movable frame 2. Then, the movable frame 2 is pushed to push the side with the honeysuckle into the extraction tank 1. The steam generator 6 continuously generates steam, and the steam is introduced into the extraction tank 1 through the steam conduit 12. The honeysuckle is heated and extracted by the steam to extract the volatile oil contained in the honeysuckle. The volatile oil follows the steam through the connecting pipe 3 into the condensation tank 4, and the steam and the volatile oil are condensed and liquefied by the condenser pipe inside the condensation tank 4. Then, the volatile oil is collected by the collection tank 5;

[0036] When the distillation of the honeysuckle on one side is completed, the steam conduit 12 is blocked by the solenoid valve. At the same time, the remaining steam inside the extraction tank 1 is discharged through the pressure relief valve on the top of the extraction tank 1. Then, the honeysuckle is also placed on the screen 10 on the other side of the movable frame 2. Then, the movable frame 2 is pushed to push the side with the new honeysuckle back into the extraction tank 1. The solenoid valve is opened again to allow the steam to enter the extraction tank 1 again to continue the distillation and extraction work. At the same time, the extracted honeysuckle is taken out of the extraction tank 1. At this time, the support plate 8 is rotated around the mounting shaft 25 to switch the upper and lower screens 10. During the flipping process, the residue of the extracted honeysuckle automatically falls off, and then the honeysuckle is laid on the surface of the upper screen 10 to prepare for the next extraction work; when the movable frame 2 is pushed again, the residue of the honeysuckle on the surface of the lower screen 10 will be scraped off by the side wall of the through groove to completely clean the residue attached to the surface of the screen 10;

[0037] By the above method, the interval time for replacing the honeysuckle can be shortened, continuous operation can be realized, and the extraction efficiency is improved; and the residue can be automatically cleaned, the working intensity is reduced, and it is convenient to use.

[0038] The extraction box 1 is provided with a flip assembly inside, and the flip assembly includes a rotating shaft 13, and the rotating shaft 13 is rotatably mounted on the connecting pipe 3. An impeller 14 is fixed on the top of the rotating shaft 13. Vertical rods 19 are symmetrically fixed on both sides of the extraction box 1. A mounting frame 15 is slidably mounted on the vertical rod 19. A spring 2 is provided above the mounting frame 15 to reset it. A connecting sleeve 16 is rotatably mounted in the middle of the top of the mounting frame 15. The connecting sleeve 16 is provided with a hexagon socket. The bottom end of the rotating shaft 13 is adapted to the connecting sleeve 16, and the bottom end of the rotating shaft 13 is slidably inserted in the hexagon socket. A connecting rod 17 is fixed below the connecting sleeve 16, and a fixing rod 22 is fixed at the bottom of the connecting rod 17. A lever 23 is fixed below the fixing rod 22. Horizontal plates 20 are fixed to the bottom ends of the vertical rods 19 on both sides, and a magnetic block 21 is fixed at the bottom of the horizontal plate 20 corresponding to the magnetic block 9;

[0039] During operation, when one side of the movable frame 2 is pushed into the extraction box 1, the magnetic block 1 9 on the mounting frame 7 is opposite to the magnetic block 2 21, attracting the magnetic block 21 to move downward, thereby driving the horizontal plate 20, the vertical rod 19, the mounting frame 15, the connecting rod 17, the fixed rod 22 and the lever 23 to move downward, so that the lever 23 fits the surface of the gauze 10, and at the same time, the connecting sleeve 16 and the rotating shaft 13 slide relatively, but the rotating shaft 13 will not leave the range of the connecting sleeve 16. During the distillation process, the steam passes through the connecting pipe 3, synchronously driving the impeller 14 to rotate, thereby driving the rotating shaft 13, the connecting sleeve 16, the connecting rod 17, the fixed rod 22 and the lever 23 to rotate, and turning the honeysuckle on the sand net through the lever 23, so that the honeysuckle is fully in contact with the steam, thereby improving the distillation rate;

[0040] When the movable frame 2 is switched, the magnetic block 1 9 and the magnetic block 2 21 are staggered, and the mounting frame 15 and the related structures below are driven upward under the rebound action of the spring 2, and finally the lever 23 moves to the top of the movable frame 2 without blocking the movement of the movable frame 2.

[0041] The levers 23 on both sides of the fixed rod 22 are arranged alternately; when working, after the lever 23 on one side turns the honeysuckle, the lever 23 on the other side turns the honeysuckle back to achieve reciprocating turning, so that the turning effect is better.

[0042] Baffles 28 are fixed to the bottom edges of the through grooves on both sides of the extraction box 1. When working, the baffles 28 extend outward relative to the outer wall of the through groove. When the movable frame 2 is pushed into the extraction box 1, the baffles 28 scrape off the residue on the surface of the gauze 10 below to prevent the fallen residue from adhering to the outer wall of the extraction box 1, which is convenient for subsequent unified cleaning.

[0043] A copper pipe 18 is arranged between the two layers of the wire mesh 10. The copper pipe 18 is respectively attached to the wire meshes 10 on both sides. A channel is provided in the middle of the two mounting shafts 25 on both sides, and both ends of the copper pipe 18 are respectively communicated with the channels on both sides. A rotary joint is installed at the end of the mounting shaft 25, and the rotary joint is connected to a cavity arranged inside the movable frame 2 through a hose 27. An oil liquid is provided in the copper pipe 18 and the cavity. During operation, the wire mesh 10 is supported by the copper pipe 18 to prevent the wire mesh 10 from deforming during the distillation process of carrying honeysuckle. In addition, heat convection is realized through the oil liquid in the cavity and the copper pipe 18, and part of the heat inside the extraction box 1 can be transferred to the copper pipe 18, and then the heat is transferred from the copper pipe 18 to the honeysuckle to be processed, so as to preheat the honeysuckle. When the honeysuckle is fed into the extraction box 1, the extraction temperature can be reached faster, thereby helping to improve the extraction efficiency.

[0044] The mounting shaft 25 is provided with a regular hexagon. During operation, by setting the mounting shaft 25 as a regular hexagon, when the rotating support plate 8 switches the wire mesh 10, a sense of jerk is generated between the mounting shaft 25 and the clamping plate 26, and then the wire mesh 10 shakes, so as to shake off the residues attached to the surface of the wire mesh 10.

[0045] Collection grooves 11 are symmetrically arranged on both sides of the extraction box 1. During operation, the honeysuckle residues falling from the wire mesh 10 will automatically fall into the lower collection grooves 11 below, which is convenient for collecting the honeysuckle residues centrally.

[0046] Multiple groups of branch pipes are evenly distributed on the side of the steam conduit 12. During operation, by providing a plurality of branch pipes, the steam can be evenly sprayed below the wire mesh 10, so that the honeysuckle can fully contact with the steam.

[0047] Embodiment 2: As Figure 6 and Figure 7 shown, compared with Embodiment 1, another implementation manner of the present invention is: the thickness of the movable frame 2 is equal to the height of the through groove on the extraction box 1. A groove is opened in the inner wall of the top of the through groove, and an elastic air ring 29 is arranged inside the groove. During operation, the side of the movable frame 2 is attached to the inner wall of the through groove to prevent steam leakage. In addition, the elastic air ring 29 is a closed ring structure formed by an elastic film and is filled with air inside. During the distillation process, the elastic air ring 29 expands due to heat and fits tightly with the movable frame 2 to further prevent steam leakage.

[0048] Working principle: The two ends of the support plate 8 are adsorbed by the magnetic block 9, so that the support plate 8 is limited, so that the support plate 8 and the gauze 10 are in a horizontal state, and then the honeysuckle can be stacked on the top of the gauze 10, and the mounting shaft 25 can move up and down between the two clamping plates 26. Under the influence of their own weight, the support plate 8 and the mounting shaft 25 are displaced to the lowest point of the mounting frame 7. At this time, the honeysuckle on the gauze 10 is located below the upper end surface of the movable frame 2. Then the movable frame 2 is pushed to push the side with the honeysuckle into the extraction box 1, and steam is continuously generated by the steam generator 6. The steam is introduced into the extraction box 1 through the steam conduit 12, and the honeysuckle is heated and extracted by the steam to extract the volatile oil contained in the honeysuckle. The volatile oil enters the condensation box 4 with the steam through the connecting pipe 3, and the steam and the volatile oil are condensed and liquefied through the condenser inside the condensation box 4, and then the volatile oil is collected through the collection box 5;

[0049] When the honeysuckle on one side is finished distilling, the steam conduit 12 is blocked by the electromagnetic valve, and the remaining steam in the extraction box 1 is discharged through the pressure relief valve on the top of the extraction box 1. Then, the honeysuckle is placed on the gauze 10 on the other side of the movable frame 2. Then, the movable frame 2 is pushed to push the side with new honeysuckle back into the extraction box 1. The electromagnetic valve is opened again to allow steam to enter the extraction box 1 again to continue the distillation and extraction work. At the same time, the extracted honeysuckle is taken out of the extraction box 1. At this time, the support plate 8 is rotated with the mounting shaft 25 as the center to switch the gauze 10 on the upper and lower sides. During the flipping process, the honeysuckle residue after extraction automatically falls off, and then the honeysuckle is laid on the surface of the upper gauze 10 to prepare for the next extraction work. When the movable frame 2 is pushed again, the honeysuckle residue on the surface of the lower gauze 10 will be hung off by the side wall of the through groove, so as to completely clean the residue attached to the surface of the gauze 10.

[0050] When one side of the movable frame 2 is pushed into the extraction box 1, the magnetic block 1 9 on the mounting frame 7 is opposite to the magnetic block 2 21, attracting the magnetic block 21 to move downward, thereby driving the horizontal plate 20, the vertical rod 19, the mounting frame 15, the connecting rod 17, the fixed rod 22 and the lever 23 to move downward, so that the lever 23 fits the surface of the gauze 10, and at the same time, the connecting sleeve 16 and the rotating shaft 13 slide relatively, but the rotating shaft 13 will not leave the range of the connecting sleeve 16. During the distillation process, the steam passes through the connecting pipe 3, synchronously driving the impeller 14 to rotate, thereby driving the rotating shaft 13, the connecting sleeve 16, the connecting rod 17, the fixed rod 22 and the lever 23 to rotate, and turning the honeysuckle on the sand net through the lever 23, so that the honeysuckle is fully in contact with the steam, thereby improving the distillation rate;

[0051] Thermal convection is achieved through the cavity and the oil in the copper pipe 18, which can transfer part of the heat inside the extraction tank 1 to the copper pipe 18, and then the copper pipe 18 transfers the heat to the honeysuckle to be processed for preheating. When the honeysuckle is fed into the extraction tank 1, it can reach the extraction temperature faster, thus helping to improve the extraction efficiency.
