Description

Technical Field

[0001] The present invention belongs to the technical field of plant extraction, and specifically relates to a separation device for plant extraction and its processing and purification process. Background Art

[0002] A separation device for plant extraction is a device specifically used to extract and separate active ingredients from plant materials. These devices usually adopt various technologies to improve the extraction efficiency and purity. Among them, the commonly used method is steam distillation, that is, at high temperature, steam is directly introduced into the plant materials, so that the aromatic components diffuse or dissolve into the water and co-distill with the steam. Subsequently, through condensation and oil-water separation, essential oils can be obtained.

[0003] Chinese invention patent CN105126378B discloses an aromatic plant distillation extraction tank, which is provided with three layer areas in the tank body, namely a combined honeycomb-shaped steaming hopper, a temperature slow-release device and a primary coagulation device; the combined honeycomb-shaped steaming hopper is composed of 2-5 layers of loading frame structures and is arranged at the lower part of the tank body, the temperature slow-release device is composed of a top layer, a middle layer and a bottom layer to form a conical hollow cover and is installed at the upper part of the tank body, and the primary coagulation device is a hollow container composed of inner and outer side walls, the top cover and the bottom plate of the tank body; this plant distillation extraction tank has low distillation efficiency and poor distillation effect.

[0004] Chinese invention patent CN115121001A discloses a device for plant essential oil distillation extraction, including a device main body, the upper surface of the device main body is connected with a sealing cover through bolts, the device main body is connected with a collection tank through the sealing cover for collecting plant essential oils, and a placement frame is arranged inside the device main body, and plants are placed through the placement frame for distillation extraction; this plant distillation extraction device has high operation difficulty and low operation safety.

[0005] When actually distilling plant raw materials and water, the steam flows upward and will partially adsorb on the inner wall of the distillation tank to form water droplets. If these water droplets cannot be scraped off and returned to the inside of the distillation tank in time, it will not only accelerate the loss of plant raw materials and water inside the distillation tank, but also the water droplets will cool down part of the inner wall of the distillation tank, thereby reducing the discharge efficiency of the steam flowing upward.

[0006] In the prior art, a scraper is often used to scrape off the water droplet impurities adsorbed on the inner wall of the distillation tank, but some water droplet impurities have too strong adsorption force and cannot be effectively scraped off, and these water droplet impurities will also adsorb on the outer surface of the scraper, thereby reducing the normal scraping effect of the scraper.

[0007] At the same time, when the discharge efficiency of the steam inside the distillation tank changes, the discharge amount of the steam changes accordingly. If the evaporation efficiency of the plant raw materials and water inside the distillation tank cannot be adjusted, it is easy to cause too much steam to be unable to be discharged, and ultimately cause the waste of steam reflux.

[0008] Moreover, when used for a long time, a large amount of plant raw material impurities or water droplet impurities are likely to adhere to the inner wall of the distillation tank. If they cannot be thoroughly and effectively scraped and cleaned, it will not only reduce the evaporation effect of plant raw materials and water, but also affect the subsequent distillation extraction.

[0024] The processing and purification process of a separation device for plant extraction as described above includes the following steps:

[0025] S1. Add the required plant raw materials and water into the evaporation cavity and heat and distill them. The steam inside the evaporation cavity rises to the end of the matching cavity. The rotating shaft rotates to drive the scraper to rotate and scrape the water droplets attached to the inner walls of the evaporation cavity and the matching cavity.

[0026] S2. When the water droplets adsorbed on the outer surface of the elastic protective film increase, the temperature at the corresponding position of the matching cavity decreases, the volume of the thermally expandable gas inside the end groove decreases, the connecting spring drives the moving plate to move towards the end close to the rotating shaft, the moving plate drives the follower rod to move towards the end close to the rotating shaft, the blocking area of the conduction hole by the follower rod decreases, and more heat medium flows inside the conduction hole.

[0028] S4. When the scraper detaches from the elastic protective film and elastically squeezes and contacts the next elastic protective film, it undergoes elastic vibration and realizes self-vibration cleaning. The stirring range of the stirring blades and the connecting rod increases, the overlapping area of the stirring hole and the docking hole increases, and the amount of plant raw materials and water flowing through increases.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. By setting up the evaporation component, agitation component, end cap component, condensation component and other components to cooperate with each other, the separation device for plant extraction has high plant separation efficiency, good plant separation effect, meets the actual plant extraction requirements, is simple to operate, safe and stable, has strong controllability, good adaptability, and can effectively improve the quality of plant distillation extraction.

[0031] 2. By setting up the scraper and elastic protective film and other components to cooperate with each other, the separation device for plant extraction uses the scraper to scrape and clean the inside of the evaporation chamber and the matching chamber, avoiding the adsorption of some impurities and affecting the extraction quality.

[0032] 3. By setting up the conduction hole and follower rod and other components to cooperate with each other, when the distillation temperature of the plant raw materials and water inside the matching chamber drops, the opening size of the conduction hole is adjusted correspondingly, thereby improving the heat conversion efficiency of the heat medium to the inside of the matching chamber and ensuring the efficient and stable flow of steam inside the matching chamber.

[0033] 4. By setting up the stirring blade and connecting rod and other components to cooperate with each other, as the scraper moves continuously, the separation device for plant extraction not only realizes the self-cleaning vibration of the scraper, but also can adjust the stirring and turbulent flow effect of the stirring blade and connecting rod on the plant raw materials and water inside the evaporation chamber, thereby ensuring the continuous and stable mixed distillation of the plant raw materials and water.

A top groove 104 is formed on the inner wall of the housing 101, and a heating pipe 103 is spirally connected inside the top groove 104. A heat medium flows inside the heating pipe 103. The heat medium inside the heating pipe 103 heats the plant raw materials and water inside the evaporation chamber 102, thereby realizing the distillation process. A waste discharge pipe 105 is provided at the bottom of the housing 101. An electromagnetic valve 106 is provided inside the waste discharge pipe 105. The top of the waste discharge pipe 105 passes through the housing 101 and is communicated with the inner bottom of the evaporation chamber 102. When the distillation is completed, the electromagnetic valve 106 is opened, and the impurities inside the evaporation chamber 102 are evenly discharged along the waste discharge pipe 105.

[0050] An installation ring 109 is provided below the outer surface of the housing 101. A support platform 107 is provided below the installation ring 109. The installation ring 109 and the support platform 107 are clamped and fixed to each other, which further improves the installation stability of the housing 101. A plurality of legs 108 are evenly provided at the bottom of the support platform 107. Buffer pads are provided at the bottoms of the legs 108. The plurality of legs 108 improve the stability of the support platform 107. A limit ring 110 is provided above the outer surface of the housing 101. The setting of the limit ring 110 ensures the installation tightness between the housing 101 and the end cover assembly 3.

[0051] The stirring assembly 2 includes a rotating shaft 201. The rotating shaft 201 rotates inside the evaporation chamber 102 to realize the stirring process. A plurality of scraping plates 209 are evenly provided on the circumferential side of the rotating shaft 201. The scraping plates 209 are all matched with the inner walls of the evaporation chamber 102 and the matching chamber 318. The scraping plates 209 rotate synchronously with the rotation of the rotating shaft 201, which further improves the scraping and cleaning effect on the impurities adsorbed on the inner wall of the evaporation chamber 102.

[0052] The outer surface of the rotating shaft 201 is rotationally connected to the axis of the housing 101 through a sealed bearing. A driving motor 202 is provided at the axis of the bottom of the housing 101. The bottom of the rotating shaft 201 passes through the housing 101 and is fixedly connected to the top output end of the driving motor 202. The driving motor 202 starts and drives the rotating shaft 201 to rotate. The rotation of the rotating shaft 201 drives the plurality of scraping plates 209 on the circumferential side to rotate, and the scraping plates 209 scrape and clean the inner walls of the evaporation chamber 102 and the matching chamber 318.

[0053] The outer surface of the rotating shaft 201 is evenly provided with a plurality of stirring blades 203. When the rotating shaft 201 rotates, the plurality of stirring blades 203 are synchronously driven to rotate. A side groove 205 is provided at the other end of the stirring blade 203. A return spring 206 is provided on the inner wall of the side groove 205. A connecting rod 207 is provided at the other end of the return spring 206. The outer surface of the connecting rod 207 is sealingly and slidably connected with the inner wall of the side groove 205. The setting of the return spring 206 further improves the elastic return performance of the connecting rod 207. At the same time, when the stirring blade 203 rotates, the connecting rod 207 is driven to rotate. The other end of the connecting rod 207 is fixedly connected to the side wall of the scraper 209. The scraper 209 is driven to rotate, a plurality of stirring holes 204 are evenly arranged inside the stirring blade 203, a plurality of docking holes 208 are evenly arranged inside the connecting rod 207, the stirring holes 204 are opposite to the docking holes 208, when the connecting rod 207 moves along the side groove 205 toward the rotating shaft 201, the overlapping area of ​​the stirring holes 204 and the docking holes 208 is reduced, and when the stirring blade 203 drives the connecting rod 207 to rotate, the plant material and water passing through the stirring holes 204 and the docking holes 208 are correspondingly reduced, thereby avoiding excessive plant material and water evaporating to form steam and causing blockage upward to affect the normal discharge efficiency, and ultimately causing waste of steam recovery.

[0054] The end cover assembly 3 includes a gourd shell 301, which is in the shape of a gourd. With the help of multiple curved structures of the gourd shell 301 itself, the adsorption and blocking of impurities in the steam are further improved to ensure the purity of the steam discharged upward. The inner cavity of the gourd shell 301 is provided with a matching cavity 318, and the matching cavity 318 is also in the shape of a gourd. Therefore, water droplets adsorbed on the inner wall of the matching cavity 318 will continue to flow under their own weight and reach the outer surface of the elastic protective membrane 316. The bottom of the gourd shell 301 and the top of the shell 101 are squeezed and contacted with each other, and the inner bottom of the matching cavity 318 and the inner top of the evaporation cavity 102 are sealed and connected with each other. Therefore, the steam formed after the plant material and water in the evaporation cavity 102 evaporate upward into the matching cavity 318 for subsequent circulation.

[0055] A plurality of torsion spring seats 304 are evenly arranged at the bottom of the gourd shell 301 and located on the outside of the shell 101. The bottom of the torsion spring seat 304 is rotatably connected with a clamp 305. The other end of the clamp 305 is clamped with the outer surface of the limiting ring 110. When the gourd shell 301 needs to be installed and fixed, it is only necessary to place the gourd shell 301 on the top of the shell 101, and at the same time rotate the plurality of clamps 305 to make them clamped and fixed with the limiting ring 110, thereby improving the sealing of the evaporation chamber 102 and the matching chamber 318, as well as the positioning accuracy of the shell 101 and the gourd shell 301.

[0056] On one side of the top of the gourd shell 301, there is a feed pipe 302. The bottom of the feed pipe 302 is connected to the inside of the matching cavity 318. Pour the required plant raw materials and water into the evaporation cavity 102 along the feed pipe 302. On the other side of the top of the gourd shell 301, there is a first thermometer 303. The bottom detection end of the first thermometer 303 passes through the gourd shell 301 and is located inside the matching cavity 318. The first thermometer 303 is used to detect the temperature values inside the evaporation cavity 102 and the matching cavity 318.

[0057] On the inner wall of the gourd shell 301, there is a heat flow cavity 306. A plurality of transfer holes 307 are uniformly connected to the inner bottom of the heat flow cavity 306. The other end of the transfer hole 307 passes through the gourd shell 301 and the housing 101 and is connected to the inner top of the top groove 104. Then, the heat medium discharged from the heating pipe 103 continues to enter the heat flow cavity 306 through the top groove 104 and the transfer holes 307 for circulation, thereby improving the upward fluidity of the steam and the constancy of its own temperature. Inside the heat flow cavity 306, there is a baffle plate 308. A plurality of conduction holes 309 are uniformly arranged inside the baffle plate 308. The baffle plate 308 blocks the heat medium inside the heat flow cavity 306 and discharges it along the plurality of conduction holes 309, thereby correspondingly adjusting the temperature values at different positions inside the matching cavity 318, further improving the steam flow discharge effect and the scraping effect of the water droplet impurities adsorbed on the inner wall of the matching cavity 318. On the top of the gourd shell 301, there is a heat outlet pipe 317. The bottom of the heat outlet pipe 317 is connected to the inner top of the heat flow cavity 306. The heat medium inside the heat flow cavity 306 finally discharges and is recycled along the heat outlet pipe 317 at the top, thereby realizing the flow of the heat medium and the heat exchange effect inside the evaporation cavity 102 and the matching cavity 318.

[0058] A plurality of communication holes 310 are uniformly arranged on the inner wall of the matching cavity 318. The end of the communication hole 310 is connected to the end of the conduction hole 309. A follower rod 315 is hermetically slidably connected inside the communication hole 310. The outer surface of the follower rod 315 is hermetically slidably connected to the inner wall of the conduction hole 309. Then, the follower rod 315 can move inside the communication hole 310 and the conduction hole 309, thereby realizing the adjustment of the blocked area of the conduction hole 309 and correspondingly adjusting the flow rate of the heat flow cavity 306 at this position and the heat exchange temperature inside the matching cavity 318.

[0059] On one side of the communication hole 310, an end groove 311 is provided. Inside the end groove 311, a moving plate 313 is hermetically and slidably connected. The side wall of the moving plate 313 is fixedly connected to the side wall of the follower rod 315. When the moving plate 313 moves, it synchronously drives the follower rod 315 to move. At one end of the end groove 311 close to the rotating shaft 201, there is a heat exchange plate 312. The end of the heat exchange plate 312 matches the inner wall of the matching cavity 318. The heat exchange plate 312 not only seals the end of the end groove 311, but also improves the heat exchange accuracy inside the end groove 311 and the matching cavity 318, further ensuring the detection accuracy and detection efficiency of the hot-expanded gas inside the end groove 311 on the corresponding position of the matching cavity 318. There is hot-expanded gas between the heat exchange plate 312 and the moving plate 313. The hot-expanded gas follows the principle of thermal expansion and contraction. On the inner wall of the end groove 311, a connecting spring 314 is provided. The other end of the connecting spring 314 is fixedly connected to the side wall of the moving plate 313. The connecting spring 314 further improves the elastic reset performance of the moving plate 313. On the inner wall of the matching cavity 318, a plurality of elastic protective films 316 are evenly provided. The plurality of elastic protective films 316 are arranged at the head and tail of the matching cavity 318, and the ends of the elastic protective films 316 are fixedly connected to the inner wall of the matching cavity 318. The inner walls of the elastic protective films 316 all match the ends of the follower rods 315. And a plurality of follower rods 315 are all located at one end of the inner side of the inner wall of the elastic protective film 316. The elastic protective film 316 will elastically deform synchronously with the movement of the follower rod 315, thereby adjusting the moving position of the scraping plate 209 and realizing the vibration cleaning of the scraping plate 209 itself, avoiding excessive steam impurities adsorbed on the outer surface of the scraping plate 209 and reducing the subsequent distillation and condensation effects.

[0060] The condensation assembly 4 includes a vertical pipe 401. The bottom of the vertical pipe 401 is communicated with the inner top of the matching cavity 318. The steam inside the matching cavity 318 enters the inside of the vertical pipe 401 upward. The top of the vertical pipe 401 is communicated with a condensation pipe 402 and continues to enter the inside of the condensation pipe 402 along the vertical pipe 401 for condensation. On one side of the condensation pipe 402, there is a second thermometer 408. The detection end of the second thermometer 408 passes through the condensation pipe 402 and is located inside the inner cavity of the condensation pipe 402. The second thermometer 408 is used to detect the temperature value inside the condensation pipe 402. The bottom of the condensation pipe 402 is communicated with a drainage pipe 403. The other end of the drainage pipe 403 is communicated with a storage tank 404. The condensed product enters the inside of the storage tank 404 along the drainage pipe 403 for storage. The bottom of the storage tank 404 is communicated with a dripping pipe 405. Inside the dripping pipe 405, there is a flow valve 409. The flow valve 409 correspondingly adjusts the dripping rate of the dripping pipe 405. Below the dripping pipe 405, there is a collection bucket 406. The product inside the storage tank 404 enters the inside of the collection bucket 406 along the dripping pipe 405 for recycling. At the bottom of the collection bucket 406, a plurality of round legs 407 are evenly provided. At the bottom of the round legs 407, there is a buffer pad. The round legs 407 improve the support of the collection bucket 406.

[0061] When actually distilling plant raw materials and water, the steam flows upward and will partially adsorb on the inner wall of the matching cavity 318 to form water droplets. If these water droplets cannot be scraped off in time and refluxed into the evaporation cavity 102, it will not only accelerate the loss of plant raw materials and water in the evaporation cavity 102, but also the water droplets will cool down part of the inner wall of the matching cavity 318, thereby reducing the upward discharge efficiency of the steam. When using the scraper 209 to scrape off the water droplet impurities adsorbed on the inner walls of the evaporation cavity 102 and the matching cavity 318, some water droplet impurities have too strong adsorption force and cannot be effectively scraped off, and these water droplet impurities will also adsorb on the outer surface of the scraper 209, further reducing the normal scraping effect of the scraper 209. At the same time, when the discharge efficiency of the steam in the matching cavity 318 changes, the steam discharge volume in the matching cavity 318 changes correspondingly. If the evaporation efficiency of the plant raw materials and water in the evaporation cavity 102 cannot be adjusted, too much steam cannot be discharged, and finally the steam will flow back and be wasted. After long-term use, a large amount of plant raw material impurities or water droplet impurities are likely to adhere to the inner walls of the evaporation cavity 102 and the matching cavity 318. If they cannot be thoroughly and effectively scraped and cleaned, it will not only reduce the evaporation effect of the plant raw materials and water, but also affect the subsequent distillation and extraction.

[0062] To solve the above problems, when the separation device for plant extraction is actually used, first, the plant raw materials and water are sent into the matching cavity 318 along the feed pipe 302, and then continue to enter the evaporation cavity 102 along the matching cavity 318 to wait for subsequent evaporation and condensation. After the feeding is completed, the feed pipe 302 is blocked, and the heat medium enters the heating pipe 103. The heating pipe 103 exchanges heat with the plant raw materials and water in the evaporation cavity 102 and further increases the temperature inside the evaporation cavity 102. When the temperature value detected by the first thermometer 303 reaches the set preset value, the heat medium in the heating pipe 103 moves upward along the transfer hole 307 into the heat flow cavity 306, thereby improving the heat exchange efficiency of the heat flow cavity 306 for the inside of the matching cavity 318. The heat medium in the heat flow cavity 306 continues to move upward and moves upward along a plurality of conduction holes 309, and finally is discharged along the heat outlet pipe 317 to complete the cycle.

[0063] At the same time, the driving motor 202 is started to drive the rotating shaft 201 to rotate. The rotating shaft 201 drives a plurality of stirring blades 203 to rotate. The stirring blades 203 drive the connecting rod 207 to rotate. At the same time, since part of the stirring hole 204 coincides with the docking hole 208, the plant raw materials and water in the evaporation cavity 102 flow along the coincident position, further improving the stirring and mixing effect, and cooperating with the stirring blades 203 and the connecting rod 207 to improve the stirring and mixing effect of the plant raw materials and water in the evaporation cavity 102 and improving the stirring and mixing quality. The connecting rod 207 drives the scraper 209 at the other end to rotate, and the scraper 209 scrapes and cleans the plant raw materials and water droplets adsorbed on the inner walls of the evaporation cavity 102 and the matching cavity 318.

[0064] The plant raw materials and water inside the evaporation chamber 102 are continuously evaporated to form steam under the combined action of the heating of the heat medium inside the heating pipe 103 and the stirring of the stirring blades 203 and the connecting rod 207. The steam continues to move upward into the matching chamber 318. The temperature inside the matching chamber 318 rises. The thermal expansion gas inside the end groove 311 expands when heated, driving the moving plate 313 to squeeze the connecting spring 314 and move away from the rotating shaft 201 end. The moving plate 313 synchronously drives the follower rod 315 to move. The outer surface of the follower rod 315 partially blocks the conduction hole 309. The heat medium inside the heat flow chamber 306 flows upward through the conduction hole 309 at a stable rate. At the same time, the follower rod 315 drives the elastic protective film 316 at the end to move and release the blockage of the rotating shaft 201. The matching chamber 318 is in a fully open state.

[0065] At this time, under the action of the gourd-shaped structure of the gourd shell 301 itself, part of the steam is blocked. Part of the steam adsorbs on the inner wall of the matching chamber 318 to form water droplets. At the same time, the stirring blade 203 drives the scraping plate 209 to rotate continuously through the connecting rod 207 and scrape and clean the inner walls of the evaporation chamber 102 and the matching chamber 318, thereby preventing water droplets from adsorbing on the inner wall of the matching chamber 318 and reducing the thoroughness of distillation. The other part of the steam continues to move upward along the vertical pipe 401 into the condensing pipe 402 for condensation. The second thermometer 408 detects the condensation temperature inside the condensing pipe 402. After condensation, the required product is formed and flows into the storage tank 404 along the drainage pipe 403. The flow valve 409 is opened, and the product inside the storage tank 404 continuously drains into the collection bucket 406 along the drip pipe 405 for recycling treatment, thus completing the distillation and purification process.

[0066] However, when the amount of water droplets adsorbed on the inner wall of the matching chamber 318 increases and continuously slides downward to the outer wall end of the elastic protective film 316, the rotation of the scraping plate 209 alone cannot achieve the scraping effect on the water droplets. Therefore, when the water droplets are adsorbed at the end of the matching chamber 318 for a long time, the temperature at this position will decrease, and ultimately the subsequent steam upward discharge condensation effect will be reduced. At this time, the volume of the thermal expansion gas inside the corresponding end groove 311 decreases under the cooling effect of the water droplets. The thrust exerted by the thermal expansion gas on the moving plate 313 decreases. Under the elastic force of the connecting spring 314, the moving plate 313 is driven to move toward the rotating shaft 201 end. The moving plate 313 synchronously drives the follower rod 315 to move toward the rotating shaft 201 end. The blocked area of the conduction hole 309 by the follower rod 315 decreases. The upward flow of the heat medium inside the heat flow chamber 306 through the conduction hole 309 increases, thereby increasing the heating efficiency of the heat medium on this position of the inner wall of the matching chamber 318, ensuring that the water droplets adsorbed on the inner wall of the matching chamber 318 continue to evaporate and discharge under the heat exchange effect of the increased temperature of the heat medium, thus improving the evaporation and cleaning effect on the water droplets.

[0067] Meanwhile, when the follower rod 315 moves towards the end close to the rotating shaft 201, the end of the follower rod 315 synchronously applies a thrust to the inner wall of the elastic protective film 316 and elastically deforms towards the end close to the rotating shaft 201. As the scraper 209 rotates continuously, the squeezing and scraping force applied to the elastic protective film 316 increases, thereby further improving the scraping and cleaning effect on the water droplets adsorbed on the outer surface of the elastic protective film 316, and preventing a large number of water droplets from accumulating on the outer surface of the elastic protective film 316 and directly affecting the scraping and cleaning effect.

[0068] Since the follower rod 315 drives the elastic protective film 316 to elastically deform towards the end close to the rotating shaft 201, the blocking area of the elastic protective film 316 against the matching cavity 318 at this position increases, the upward flow rate of the steam at this position decreases, and when the scraper 209 rotates and fits with the elastic protective film 316 for scraping, it synchronously moves towards the end close to the rotating shaft 201. The scraper 209 synchronously drives the connecting rod 207 to squeeze the return spring 206 along the side groove 205 and move towards the end close to the rotating shaft 201. The stirring range of the connecting rod 207 and the stirring blade 203 for the plant raw materials and water inside the evaporation chamber 102 decreases, and at the same time, the overlapping area of the stirring hole 204 and the docking hole 208 decreases, and the amount of plant raw materials and water passing through the overlapping part of the stirring hole 204 and the docking hole 208 decreases, thereby reducing the stirring effect of the stirring blade 203 and the connecting rod 207 on the plant raw materials and water inside the evaporation chamber 102, and preventing too much plant raw materials and water from distilling into steam and then adhering to the outer surface of the elastic protective film 316 upwards, further improving the stirring and distillation adaptability of the plant raw materials and water.

[0069] When the scraper 209 rotates continuously and reaches the position where the end of the follower rod 315 is separated from the outer wall of the elastic protective film 316, the scraper 209 moves away from the end close to the rotating shaft 201 under the elastic force applied by the return spring 206 to the connecting rod 207. The scraper 209 collides with the next elastic protective film 316 by mutual extrusion. At this time, due to the different amounts of elastic deformation of the adjacent follower rods 315 driving the elastic protective films 316, the scraper 209 moves reversely in the matching cavity 318 and elastically collides and vibrates with the inner wall of the matching cavity 318. By means of this vibration, not only can the water droplets adsorbed on the outer surface of the elastic protective film 316 and the inner walls of the evaporation chamber 102 and the matching cavity 318 be elastically vibrated and separated, but also a reverse elastic vibration force can be applied to the scraper 209, thereby vibrating and cleaning the water droplets attached to the outer surface of the scraper 209, ensuring that the water droplets flow back downwards into the evaporation chamber 102 for subsequent distillation, improving the elastic vibration cleaning effect, with higher recovery efficiency and better cleaning effect.

[0070] Meanwhile, when the scraper 209 moves, it synchronously drives the connecting rod 207 to continuously move horizontally inside the side groove 205, synchronously driving the change in the overlapping area of the stirring hole 204 and the docking hole 208. Then, the stirring effects of the stirring blade 203 and the connecting rod 207 on the plant raw materials and water inside the evaporation chamber 102 change synchronously. Moreover, the plant raw materials and water generate pulsed torrents inside the stirring hole 204 and the docking hole 208, thereby further improving the mixing and flowing effects of the plant raw materials and water inside the evaporation chamber 102, and ensuring thorough mixing and pulse variability.

[0071] Similarly, after the water droplets at the elastic protective film 316 are scraped and cleaned, the temperature value at the corresponding position of the matching cavity 318 continuously increases to the initial value. At this time, the volume of the thermally expanded gas inside the end groove 311 increases and drives the moving plate 313 to squeeze the connecting spring 314 and move to the initial value. The moving plate 313 drives the follower rod 315 to move away from the rotating shaft 201 end to the initial value. The elastic protective film 316 matches the inner wall of the matching cavity 318. Meanwhile, the blocking area of the follower rod 315 for the conduction hole 309 returns to the initial value, the flow rate of the heat medium flowing upward along the conduction hole 309 inside the heat flow cavity 306 returns to the initial value, the heating temperature of the heat medium for the steam inside the matching cavity 318 returns to the initial value, the scraper 209 drives the connecting rod 207 to move to the initial value inside the side groove 205, and all components resume normal operation.

[0072] When the distillation of the plant raw materials and water inside the evaporation chamber 102 is completed, the solenoid valve 106 is opened, and the temperature inside the heating tube 103 further increases. At this time, the volume of the thermally expanded gas inside the end groove 311 reaches the maximum and drives the moving plate 313 to squeeze the connecting spring 314 and move away from the rotating shaft 201 end to the maximum value. The moving plate 313 synchronously drives the follower rod 315 to move away from the rotating shaft 201 end to the maximum value. The scraper 209 fits with the inner walls of the evaporation chamber 102 and the matching cavity 318. The rotating shaft 201 rotates to drive the stirring blade 203 to rotate. The stirring blade 203 drives the scraper 209 to rotate through the connecting rod 207 inside the side groove 205. The scraper 209 thoroughly and effectively scrapes and cleans the inner walls of the evaporation chamber 102 and the matching cavity 318, and the plant raw materials and water inside the evaporation chamber 102 are discharged along the impurity discharge pipe 105, thus completing the distillation process.

[0073] After that, no heat medium is passed into the heating pipe 103. The volume of the thermally expanded gas inside the end slot 311 shrinks to the minimum value. Under the elastic force of the connecting spring 314, the moving plate 313 is driven to move towards the rotating shaft 201 end to the maximum value. The moving plate 313 drives the follower rod 315 to move towards the rotating shaft 201 end to the maximum value. The follower rod 315 synchronously drives a plurality of elastic protective films 316 to move to the maximum value. Then, the plurality of elastic protective films 316 squeeze the scraper 209 and fit with the outer surface of the rotating shaft 201. The matching cavity 318 is closed and blocked at this position, thereby preventing external impurities from entering the evaporation cavity 102 and contaminating the subsequent distillation process.

[0074] The separation device for plant extraction has high plant separation efficiency and good plant separation effect, meeting the actual plant extraction requirements. It is simple to operate, safe and stable, with strong controllability and good adaptability, and can effectively improve the quality of plant distillation extraction. Moreover, it can use the scraper 209 to clean the inside of the evaporation cavity 102 and the matching cavity 318, preventing some impurities from adsorbing and affecting the extraction quality. At the same time, when the distillation temperature of the plant raw materials and water inside the matching cavity 318 drops, the opening size of the conduction hole 309 is correspondingly adjusted, thereby improving the heat transfer efficiency of the heat medium to the inside of the matching cavity 318 and ensuring the efficient and stable flow of steam inside the matching cavity 318. And as the scraper 209 continuously moves, not only the vibration self-cleaning of the scraper 209 is realized, but also the stirring and turbulent flow effects of the stirring blades 203 and the connecting rod 207 on the plant raw materials and water inside the evaporation cavity 102 can be adjusted, so as to ensure the continuous and stable mixing and distillation of the plant raw materials and water.

[0075] Embodiment 2

[0076] The processing and purification process of a separation device for plant extraction as described above includes the following steps:

[0077] S1. Add the required plant raw materials and water into the evaporation cavity 102 and carry out heating and distillation. The steam inside the evaporation cavity 102 rises to the matching cavity 318 end. The rotating shaft 201 rotates to drive the scraper 209 to rotate and scrape the water droplets attached to the inner walls of the evaporation cavity 102 and the matching cavity 318.

[0078] S2. When the water droplets adsorbed on the outer surface of the elastic protective film 316 increase, the temperature at the corresponding position of the matching cavity 318 decreases, the volume of the thermally expanded gas inside the end slot 311 decreases, the connecting spring 314 drives the moving plate 313 to move towards the rotating shaft 201 end, the moving plate 313 drives the follower rod 315 to move towards the rotating shaft 201 end, and the blocking area of the conduction hole 309 by the follower rod 315 decreases, and more heat medium flows inside the conduction hole 309.

[0079] S3. When the follower rod 315 moves towards the end close to the rotating shaft 201, it synchronously drives the elastic protective film 316 to undergo elastic deformation. The squeegee 209 is squeezed against the elastic protective film 316 and moves towards the end close to the rotating shaft 201. The squeegee 209 drives the connecting rod 207 to move along the side groove 205 while squeezing the return spring 206, and the overlapping area of the stirring hole 204 and the docking hole 208 decreases.

[0080] S4. When the squeegee 209 disengages from the elastic protective film 316 and elastically squeezes and contacts the next elastic protective film 316, it undergoes elastic vibration and realizes self-vibrating cleaning. The stirring range of the stirring blade 203 and the connecting rod 207 increases, the overlapping area of the stirring hole 204 and the docking hole 208 increases, and the amount of plant raw materials and water flowing through increases.

[0081] By further defining the purification process, the purification quality is improved and the purification efficiency is ensured.
