DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Example 1, reference Figure 1 - Figure 3 , which is the first embodiment of the present invention, provides a waste residue solvent recovery mechanism for preparing natural fragrances, the device comprising: a tank unit 100, a separation unit 200, and a recovery unit 300.

[0031] The tank unit 100 includes a tank body 101, a support member 103 disposed at the bottom of the tank body 101, and a closure member 102 disposed at the top of the tank body 101, and the closure member 102 is slidably connected to the separation component 201. When separating and recycling the waste of natural flavors, the operator opens the closure member 102 and then puts the waste of natural flavors into the separation component 201, and then closes the closure member 102 to start separating and recycling the waste of natural flavors. The separation unit 200 includes a separation component 201 disposed inside the tank body 101, and a stirring component 202 disposed on the separation component 201. After the operator puts the waste of natural flavors into the separation component 201 and closes the closure 102, the separation component 201 starts to drive and operate. When the separation component 201 is in operation, the waste of natural flavors inside the separation component 201 begins to be stirred and turned by the threaded rotating rod 2015 inside the separation component 201, and the waste inside the separation component 201 is driven by the unique driving of the electric push rod 2018 inside the separation component 201. The stirring and flipping can be performed up and down in a reciprocating manner, so that the solvent inside the waste can be effectively separated, and bidirectional stirring can be achieved through the separation component 201. The bidirectional stirring can generate reciprocating stirring forces in two directions, which helps to prevent the waste residue from gathering or forming blockage inside the separation component 201. The up and down stirring forces can disperse the waste residue and push it to different directions, thereby keeping the filtration channel unobstructed and ensuring that the solvent can flow smoothly. At the same time, the bidirectional stirring can also promote the rapid separation of the waste residue and the solvent, which helps to separate the solvent inside the waste residue, thereby extracting more fragrance components, and improving the efficiency of the entire recycling process; The recycling unit 300 includes a recycling component 301 disposed at the bottom of the separation component 201, and the recycling component 301 is connected to the tank body 101. After the separation component 201 stirs and separates the spice waste, the remaining waste is intercepted inside the separation component 201, and under the influence of gravity, the waste inside the separation component 201 falls into the recycling component 301, and the solvent filtered by the separation component 201 is discharged through the stirring component 202, and the clean waste remains in the recycling component 301 for unified treatment, and when the separation component 201 needs to be cleaned, the stirring component 202 on the separation component 201 can also effectively remove the impurities remaining on the inner wall of the separation component 201, so that they fall together into the recycling component 301 for collection.

[0032] During use, after the production of natural fragrances is completed, when the organic compounds in the residual waste materials are separated and recovered, the operator opens the closure 102 and then puts the waste materials containing organic compounds into the separation component 201, and then closes the closure 102 to start separating and recovering the waste materials. After the operator puts the organic compound waste materials into the separation component 201 and closes the closure 102, the separation component 201 starts to drive and operate. When the separation component 201 is operating, the waste materials of natural fragrances in the separation component 201 begin to be stirred and turned by the threaded rotating rod 2015 inside the separation component 201, and are rotated by the electric push rod 218 inside the separation component 201. Under the unique drive of , the waste inside the separation component 201 can be stirred and flipped up and down repeatedly, so that the solvent inside the waste can be effectively separated, and two-way stirring can be achieved through the separation component 201. The two-way stirring can generate reciprocating stirring force in two directions, which helps to prevent the waste from agglomerating or forming blockage inside the separation component 201, and the waste residue can be dispersed and pushed to different directions by the up and down stirring force, so as to keep the filtration channel unobstructed and ensure that the solvent can flow smoothly. At the same time, the two-way stirring can also promote the rapid separation of the waste and the solvent, help to separate the solvent inside the waste, and then separate the organic compounds, thereby improving the efficiency of the entire recycling process.

[0033] In the production process of citrus essential oils (such as orange peel essential oil and lemon essential oil), cold pressing or distillation is usually used to extract flavors from citrus peels. During the extraction process, a large amount of citrus peel waste containing residual essential oil components will be generated. In these citrus peel wastes, there are still many flavor components, such as pigments or cellulose. At this time, it is necessary to pour all the residual citrus peel waste into the interior of the separation component 201, and then add organic solvents such as ethanol and acetone to perform secondary extraction on the citrus peel waste to recover the residual pigment or cellulose components, so that the residual flavor components in the waste can be secondary squeezed, and after the organic solvents such as ethanol and acetone and the waste are stirred and separated in the separation component 201, the separation component 201 filters and separates the solution, and the recovery component 301 recovers the pigment or cellulose in the residual citrus peel waste, thereby improving the recovery efficiency of the pigment or cellulose and reducing the waste of other available resources in the citrus peel waste.

[0034] After the organic waste is stirred and separated by the separation component 201, the remaining waste is intercepted inside the separation component 201, and under the influence of gravity, the waste inside the separation component 201 falls into the recovery component 301, and the solvent filtered by the separation component 201 is discharged through the stirring component 202, and the clean waste remains in the recovery component 301 for unified treatment, and when the separation component 201 needs to be cleaned, the stirring component 202 on the separation component 201 can also effectively remove the impurities remaining on the inner wall of the separation component 201, so that they fall together into the recovery component 301 for collection, and by combining the rotation driven by the separation component 201 with the up and down reciprocating motion, the waste residue is fully stirred inside the separation component, and two-way stirring is realized in the separation component 201. The two-way stirring can generate reciprocating stirring force in two directions, which effectively avoids the waste aggregation or blockage caused by traditional single-direction stirring, significantly improves the separation efficiency of waste and solvent, and realizes the rapid separation of solvent inside the waste.

[0035] Example 2, reference Figure 1 - Figure 8, which is the second embodiment of the present invention, which is different from the first embodiment in that: the separation component 201 includes a connecting ring 2011 arranged on the inner wall of the tank body 101, a filter barrel 2012 arranged at the bottom of the inner wall of the connecting ring 2011, a moving ring 2013 slidably arranged on the outer diameter of the filter barrel 2012, and an electric push rod 2018 arranged on the moving ring 2013, and the electric push rod 2018 is connected to the connecting ring 2011, and the inner wall of the moving ring 2013 is provided with a moving rod 2014, and the other end of the moving rod 2014 is slidably provided with a threaded rotating rod 2015, and the threaded rotating rod 2015 is provided on the inner wall of the moving ring 2013. The bottom of the rotating rod 2015 is rotatably connected to the recycling component 301, a limiting groove 2017 is set on the outer diameter of the filter barrel 2012, and the limiting groove 2017 is slidably connected to the moving rod 2014, and the top of the threaded rotating rod 2015 is rotatably provided with a limiting rod 2016, and the limiting rod 2016 is connected to the closing member 102. After the production of natural fragrance is completed, when the organic compounds in the residual waste are separated and recycled, the operator opens the closing member 102 and then puts the waste of natural fragrance into the separation component 201, and then closes the closing member 102, so that all the waste is poured into the filter barrel 2 012, and then the electric push rod 2018 begins to extend downward, so that the moving ring 2013 moves downward along the surface of the filter barrel 2012, and while the moving ring 2013 moves, the moving rod 2014 on the moving ring 2013 also moves downward along the threaded rotating rod 2015, so that the threaded rotating rod 2015 also begins to rotate, and begins to stir and separate the waste inside the filter barrel 2012, and the electric push rod 2018 extends to the bottom and retracts upward again, so that the moving ring 2013 again rotates in the opposite direction with the threaded rotating rod 2015 The movable rod 2014 on the movable ring 2013 can stably carry the threaded rotating rod 2015 to rotate up and down under the limitation of the limiting groove 2017, so that the waste material inside the filter barrel 2012 can be repeatedly stirred, and the waste residue can be dispersed and pushed to different directions through the up and down stirring force of the threaded rotating rod 2015, so as to keep the filtration channel unobstructed and ensure that the solvent can flow smoothly. At the same time, the two-way stirring can also promote the rapid separation of the waste material and the solvent, so that the solution inside the waste material can be separated, which effectively avoids the problem of waste residue aggregation or blockage caused by traditional single-direction stirring.

[0036] Compared with Example 1, further, the stirring assembly 202 includes a stirring rod 2021 arranged on the outer diameter of the threaded rotating rod 2015, a return spring 2022 arranged inside the stirring rod 2021, and a brush 2023 arranged at the other end of the return spring 2022, and the brush 2023 rotates on the inner wall of the tank body 101, and a bottom shell 2024 is arranged at the bottom of the tank body 101, and a sewage valve 2025 is arranged at one end of the bottom shell 2024. When the electric push rod 2018 drives the threaded rotating rod 2015 to rotate and stir to separate the waste, because the threaded rotating rod 2015 also carries the stirring while rotating, The rod 2021 and the brush 2023 rotate, and the return spring 2022 inside the stirring rod 2021 also makes the brush 2023 always stick to the inner wall of the filter barrel 2012, so that the inside of the filter barrel 2012 can be scraped during separation to prevent waste from sticking to the inner wall of the filter barrel 2012, and when the stirring rod 2021 rotates, a certain centrifugal force will be generated so that all the waste on the stirring rod 2021 can be thrown away. At the same time, when the electric push rod 2018 drives the moving ring 2013 to move, it can also hang on the outer wall of the filter barrel 2012 to prevent the filtered solution from sticking.

[0037] During use, after the production of natural fragrances is completed, when the organic compounds in the residual waste are separated and recovered, the operator opens the closure 102 and then puts the waste of natural fragrances into the interior of the separation component 201, and then closes the closure 102, so that all the waste is poured into the interior of the filter barrel 2012, and then the electric push rod 2018 begins to extend downward, so that the moving ring 2013 moves downward along the surface of the filter barrel 2012, and while the moving ring 2013 moves, the moving rod 214 on the moving ring 2013 also moves downward along the threaded rotating rod 2015, so that the threaded rotating rod 2015 also starts to rotate, and starts to The waste material inside the filter barrel 2012 is stirred and separated, and when the electric push rod 2018 extends to the bottom, it retracts upward again, so that the moving ring 2013 again rotates in the opposite direction with the threaded rotating rod 2015, and at the same time, under the limitation of the limiting groove 2017, the moving rod 2014 on the moving ring 2013 can stably rotate up and down with the threaded rotating rod 2015, so that the waste material inside the filter barrel 2012 can be repeatedly stirred, and the solution inside the waste material can be separated, which effectively avoids the problem of waste residue aggregation or blockage caused by traditional single-direction stirring, significantly improves the separation efficiency of waste residue and solvent, and realizes the rapid separation of the solvent inside the waste residue.

[0038] When the electric push rod 2018 drives the threaded rotating rod 2015 to rotate and stir to separate the waste, because the threaded rotating rod 2015 also rotates with the stirring rod 2021 and the brush 2023, the return spring 2022 inside the stirring rod 2021 also makes the brush 2023 always stick to the inner wall of the filter barrel 2012, so that the inner wall of the filter barrel 2012 can be scraped during separation to prevent the waste from sticking to the inner wall of the filter barrel 2012, and when the stirring rod 2021 rotates, a certain centrifugal force is generated so that the waste on the stirring rod 2021 can be thrown away. At the same time, when the electric push rod 2018 drives the moving ring 2013 to move, the outer wall of the filter barrel 2012 can also be hung out to prevent the filtered solution from sticking.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3, reference Figure 1 - Fig.10 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the recovery component 301 includes a filter fence 3011 arranged at the bottom of the filter barrel 2012, a filter ring plate 3012 arranged at the bottom of the filter fence 3011, and a collection valve 3013 arranged at the bottom of the filter ring plate 3012. A rotation limit ring 3014 is arranged on the top of the filter fence 3011, and the rotation limit ring 3014 is rotatably connected to the threaded rotating rod 2015. The outer diameter of the filter ring plate 3012 is provided with a filter hole with a diameter of 3 mm. When the electric push rod 2018 drives the threaded rotating rod 2015, the filter hole 3012 is provided with a filter hole with a diameter of 3 mm. After the rotating rod 2015 stirs and separates the waste inside the filter barrel 2012, the solution inside the waste flows to the inside of the tank body 101 through the filtration of the filter barrel 2012, and then falls into the inside of the bottom shell 2024, and finally the solution is discharged and collected through the sewage valve 2025. Then the waste remaining in the filter barrel 2012 falls into the filter ring plate 3012 through the filter fence 3011, and is filtered again by the filter ring plate 3012, so that the solution inside the waste is further separated, and the separated natural fragrance waste is collected and processed through the collection valve 3013.

[0041] During use, after the electric push rod 2018 drives the threaded rotating rod 2015 to stir and separate the waste inside the filter barrel 2012, the solution inside the waste flows to the inside of the tank body 101 through the filtration of the filter barrel 2012, and then falls into the inside of the bottom shell 2024, and finally the solution is discharged and collected through the sewage valve 2025, and then the waste remaining in the filter barrel 2012 falls into the filter ring plate 3012 through the filter fence 3011, and is filtered again by the filter ring plate 3012, so that the solution inside the waste is further separated, and the separated natural fragrance waste is collected and processed through the collection valve 3013, and the synergistic effect of the filter barrel 2012 and the filter ring plate 3012, the separated solvent can be discharged smoothly, and the solid waste residue is accurately recovered, avoiding waste of resources. At the same time, the automated design of the device reduces manual intervention, reduces operational complexity and energy consumption, effectively shortens the operation time, and improves production efficiency.

[0042] The remaining structure is the same as that of Example 2.
