Description

Technical Field

[0001] The invention relates to the technical field of peppermint oil production, and in particular to a method for preparing peppermint oil volatile oil. Background Art

[0002] Peppermint oil, also known as peppermint oil, is a volatile oil obtained by steam distilling and freezing the fresh stems and leaves of the Lamiaceae plant mint, and then partially removing the brain. It can be used in daily chemical products to play a cooling and bactericidal role as well as to provide a mint flavor. It can also be used as a fragrance agent in perfumes.

[0003] The invention patent with authorization announcement number CN1027752 Torsion Spring 77 discloses a menthol and menthol oil production process, which uses mint powder or mint oil as production raw materials, liquefies the raw materials in a drying room to form mint raw oil; pumps the liquefied mint raw oil into a dehydration tank for dehydration; enters a blending kettle and is adjusted to contain 87.5-88.5% of L-menthol; enters a filter press to filter impurities; enters a crystallization reservoir for crystallization; separates semi-finished menthol and ice oil; the semi-finished menthol is dried, cooled, and packaged to obtain finished menthol; and the ice oil is frozen to separate the raw menthol oil.

[0004] However, after actual application by technicians skilled in the art, it was found that the above production process still has some shortcomings. The most obvious one is that when using dehydrated raw oil to prepare peppermint oil, the dehydrated raw oil needs to be input into a distillation kettle, and the peppermint oil and residue are separated under the condition of controlling the temperature and vacuum degree. The separated peppermint oil is filtered by a filter press to obtain peppermint oil, while the residue will remain in the distillation kettle. At this time, if the residue in the distillation kettle is manually cleaned, due to the influence of the residual temperature of the distillation, not only is the cleaning difficult, which is easy to cause residues, but the distillation kettle also needs to be shut down for a long time, thereby reducing the overall preparation efficiency of the peppermint oil.

[0005] Therefore, it is necessary to invent a method for preparing peppermint oil volatile oil to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a method for preparing volatile oil of peppermint oil, which comprises a first driving mechanism, an upper distillation mechanism, a second driving mechanism, a residue throwing mechanism and a lower distillation mechanism, so that the first driving mechanism is used to drive the upper distillation mechanism and the second driving mechanism to move downward synchronously, and then the upper distillation mechanism drives the lower distillation mechanism to rotate to a horizontal state for feeding. After the distillation is completed, the first driving mechanism drives the upper distillation mechanism and the second driving mechanism to move upward and reset. After the upper distillation mechanism moves upward, the seal of the lower distillation mechanism is released, and the lower distillation mechanism is automatically reset. Subsequently, the second driving mechanism drives the lower distillation mechanism to rotate continuously through the residue throwing mechanism, and then the residue is thrown to a collecting container by centrifugal force. Inside the plate, during this process, the residue throwing mechanism triggers the lower distillation mechanism, and then all the residues are scraped off to solve the problem proposed in the above background technology that when using dehydrated raw oil to prepare peppermint oil, the dehydrated raw oil needs to be input into the distillation kettle, and the peppermint oil and the residue are separated under the condition of controlling the temperature and vacuum degree. The separated peppermint oil is filtered by a filter press to obtain peppermint oil, while the residue will remain in the distillation kettle. At this time, if the residue in the distillation kettle is manually cleaned, due to the influence of the residual temperature of the distillation, not only is the cleaning difficult, but it is easy to cause residues, and the distillation kettle needs to be shut down for a long time, thereby reducing the overall preparation efficiency of the peppermint oil.

After the distillation is completed, the first driving mechanism drives the upper distillation mechanism and the second driving mechanism to move upward and reset. After the upper distillation mechanism moves upward, the seal on the lower distillation mechanism is released, and the lower distillation mechanism automatically resets. Then the second driving mechanism drives the lower distillation mechanism to rotate continuously through the residue throwing mechanism, and then uses centrifugal force to throw the residue into the collection plate.

[0011] Preferably, the residue throwing mechanism comprises an intermediate plate, an annular plate, a first gear ring, a threaded sleeve, a first gear, a second gear ring and an L-shaped arm; The intermediate plate is fixedly arranged in the middle of the inner side of the outer shell, the annular plate is rotatably arranged on the inner side of the intermediate plate through a bearing, the first gear ring is fixedly sleeved on the outer bottom of the annular plate, the threaded sleeve is penetrated and arranged on the left side of the bottom of the intermediate plate and is rotatably connected with the intermediate plate through a bearing, the first gear is sleeved on the outer side of the threaded sleeve through an overrunning clutch and meshes with the first gear ring, the second gear ring is rotatably arranged on the inner top of the annular plate through a bearing, and the L-shaped arm is fixedly arranged on the top of the second gear ring and is fixedly connected to the inner wall of the outer shell.

[0012] Preferably, the lower distillation mechanism comprises a lower distillation kettle, a rotating shaft, a U-shaped scraper, a transverse block, a second gear, a connecting shaft, a torsion spring and a third gear; The lower distillation kettle is located on the inner side of the annular plate and a heating resistor is arranged inside the lower distillation kettle. The rotating shaft passes through the lower distillation kettle and is rotatably connected to the lower distillation kettle through a bearing. The U-shaped scraper is fixedly sleeved on the outer side of the rotating shaft and fits with the inner wall of the lower distillation kettle. The transverse block is opened at the right end of the rotating shaft. The second gear is fixedly arranged at the left end of the rotating shaft and meshes with the second gear ring. Two connecting shafts are arranged, and the two connecting shafts are respectively fixedly arranged on the front and back sides of the lower distillation kettle. The connecting shaft passes through the annular plate and is rotatably connected to the annular plate through a bearing. The torsion spring is sleeved on the outer side of the connecting shaft and is fixedly connected between the lower distillation kettle and the annular plate. The third gear is sleeved on the outer end of the adjacent connecting shaft through an overrunning clutch.

[0013] Preferably, the method specifically comprises the following steps: S1, start the driving motor, the driving motor drives the reciprocating screw to rotate, the reciprocating screw drives the outer sleeve to move downward when rotating, the outer sleeve drives the one-way screw to move downward through the outer sleeve plate, the column and the second spring when the outer sleeve moves downward, and the inner sleeve is driven downward by the first spring at the same time, the one-way screw drives the threaded sleeve to rotate when moving downward, at this time, due to the limitation of the overrunning clutch, the first gear does not rotate, the inner sleeve drives the upper distillation mechanism to move downward as a whole, and in addition, the reciprocating screw drives the square column to rotate through the square groove during the rotation process, and the square column drives the transverse groove to rotate when rotating; S2, when the downward movement distance of the outer sleeve reaches the first threshold, the rack meshes with the third gear, and when the rack continues to move downward, the rack drives the third gear to rotate, and when the third gear rotates, the lower distillation kettle is driven to gradually rotate from a vertical state to a horizontal state through the connecting shaft. In this process, the dehydrated crude oil is added into the lower distillation kettle through the top opening of the lower distillation kettle; S3, when the outer sleeve moves downward to the second threshold, the rack is no longer meshed with the third gear. At this time, since the lower distillation kettle is filled with dehydrated wool oil, the lower distillation kettle cannot be reset under the drive of the torsion spring due to the gravity of the dehydrated wool oil. S4, when the downward movement distance of the outer sleeve reaches the third threshold, the upper distillation kettle is tightly fitted on the top of the lower distillation kettle, and the transverse block is located on the inner side of the transverse groove. During the rotation of the driving shaft, the rotating shaft is driven to rotate continuously through the transverse groove and the transverse block. When the rotating shaft rotates, the U-shaped scraper is driven to rotate continuously inside the lower distillation kettle, thereby scraping the inner wall of the lower distillation kettle and stirring the dehydrated crude oil at the same time; S5, start the heating resistors inside the upper distillation kettle and the lower distillation kettle and the vacuum pump connected to the vacuum tube, and then start the distillation and collection of peppermint oil. At this time, due to the obstruction of the lower distillation kettle, the upper distillation kettle cannot move downward further, that is, the inner sleeve cannot move downward further. Subsequently, as the outer sleeve continues to move downward, the first spring is continuously compressed, and at the same time, the outer sleeve continues to drive the one-way screw to move downward through the column and the second spring; S6, when the downward movement distance of the outer sleeve reaches the fourth threshold, the outer sleeve moves to the bottom of the reciprocating thread outside the reciprocating screw, and the two magnets are attracted to each other. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves upward and resets. During the upward movement of the outer sleeve, the compressed first spring is gradually restored, and the column is driven upward through the outer sleeve plate. At this time, due to the mutual attraction of the two magnets, the one-way screw cannot rise synchronously, so the second spring is continuously stretched; S7, when the upward movement distance of the outer sleeve reaches the fifth threshold, the compressed first spring recovers, and when the outer sleeve continues to move upward, the outer sleeve drives the upper distillation kettle upward through the first spring and the inner sleeve, and the upper distillation kettle gradually drives the third gear to rotate through the rack during the upward movement. At this time, due to the limitation of the overrunning clutch, the third gear cannot drive the connecting shaft to rotate, and because the lower distillation kettle is detached from the top of the upper distillation kettle and only residues remain inside the lower distillation kettle, the torsion spring gradually drives the lower distillation kettle to gradually restore the vertical state after the upper distillation kettle moves upward; S8. When the upward movement distance of the outer sleeve reaches the sixth threshold, the lower distillation kettle is reset. At this time, the top of the second gear is meshed with the bottom of the second gear ring, and the second spring is stretched to the extreme value. Subsequently, as the outer sleeve continues to move upward, the two magnets separate from each other, and the stretched second spring drives the one-way screw to move upward and reset. During the upward movement of the one-way screw, the first gear is driven to rotate through the threaded sleeve. During the rotation of the first gear, the annular plate is driven to rotate through the first gear ring. When the annular plate rotates, the lower distillation mechanism is driven to rotate as a whole. During this process, the second gear drives the rotating shaft to rotate due to the second gear ring. The rotating shaft scrapes off the residue attached to the inner wall of the lower distillation kettle through the U-shaped scraper, and then is thrown into the collection plate for collection under the action of the centrifugal force generated by the rotation of the lower distillation mechanism; S9, when the upward movement distance of the outer sleeve reaches the seventh threshold, the outer sleeve arrives at the initial position, that is, the top of the reciprocating thread on the outside of the reciprocating screw, and then as the reciprocating screw continues to rotate, the outer sleeve moves down again.

[0014] Technical effects and advantages of the present invention: The present invention is provided with a first driving mechanism, an upper distillation mechanism, a second driving mechanism, a residue throwing mechanism and a lower distillation mechanism, so that the first driving mechanism can be used to drive the upper distillation mechanism and the second driving mechanism to move downward synchronously, and then the upper distillation mechanism drives the lower distillation mechanism to rotate to a horizontal state for feeding. After the distillation is completed, the first driving mechanism drives the upper distillation mechanism and the second driving mechanism to move upward and reset. After the upper distillation mechanism moves upward, the seal on the lower distillation mechanism is released, and the lower distillation mechanism is automatically reset. Subsequently, the second driving mechanism drives the lower distillation mechanism to rotate continuously through the residue throwing mechanism, and then the residue is thrown into the collection plate by centrifugal force. In this process, the residue throwing mechanism triggers the lower distillation mechanism, and then all the residues are scraped off. Compared with the same type of devices and methods in the prior art, the present invention has a higher degree of automation, and can quickly clean up the residues without being affected by the residual temperature after the distillation is completed, saving manpower while avoiding too long downtime to affect the distillation efficiency. In addition, it can avoid the residues from adhering to the inner wall of the lower distillation kettle, and the cleaning effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention provides Figure 1-Figure 5 A method for preparing a volatile oil of peppermint oil is shown, and the method for preparing the volatile oil of peppermint oil is realized by a volatile oil preparation device of peppermint oil, and the volatile oil preparation device of peppermint oil comprises a shell 1, a collecting plate 2 is placed at the bottom of the inner side of the shell 1, a first driving mechanism 3 is arranged at the top of the inner side of the shell 1, an upper distillation mechanism 4 is arranged at the bottom of the first driving mechanism 3, and a second driving mechanism 5 is arranged outside the first driving mechanism 3, a residue throwing mechanism 6 is arranged in the middle of the inner side of the shell 1, and a lower distillation mechanism 7 is rotatably arranged inside the residue throwing mechanism 6; The first driving mechanism 3 drives the upper distillation mechanism 4 and the second driving mechanism 5 to move downward synchronously, and then the upper distillation mechanism 4 drives the lower distillation mechanism 7 to rotate to a horizontal state for feeding. After the distillation is completed, the first driving mechanism 3 drives the upper distillation mechanism 4 and the second driving mechanism 5 to move upward and reset. After the upper distillation mechanism 4 moves upward, the seal on the lower distillation mechanism 7 is released, and the lower distillation mechanism 7 is automatically reset. Then the second driving mechanism 5 drives the lower distillation mechanism 7 to rotate continuously through the residue throwing mechanism 6, and then uses centrifugal force to throw the residue into the collection plate 2.

[0023] like Figure 2 As shown, the first driving mechanism 3 includes a reciprocating screw 31, a driving motor 32, a square slot 33, an outer sleeve 34, a first spring 35 and an inner sleeve 36, wherein the reciprocating screw 31 passes through the outer shell 1 and is rotatably connected to the outer shell 1 through a bearing, the driving motor 32 is fixedly arranged on the top of the outer shell 1 and is transmission-connected to the reciprocating screw 31, the square slot 33 is opened at the bottom end of the reciprocating screw 31, the outer sleeve 34, the first spring 35 and the inner sleeve 36 are sequentially sleeved and arranged on the outside of the reciprocating screw 31 from top to bottom, the outer sleeve 34 is transmission-connected to the reciprocating screw 31, the first spring 35 is fixedly connected between the outer sleeve 34 and the inner sleeve 36, the inner sleeve 36 is slidably connected to the reciprocating screw 31 and is slidably arranged on the inner side of the outer sleeve 34.

[0024] By setting the above structure, the driving motor 32 can drive the reciprocating screw 31 to rotate. When the reciprocating screw 31 rotates, the outer sleeve 34 is driven to move downward. When the outer sleeve 34 moves downward, the inner sleeve 36 is driven downward through the first spring 35. When the inner sleeve 36 moves downward, the upper distillation mechanism 4 is driven downward as a whole.

[0025] like Figure 3 As shown, the upper distillation mechanism 4 includes an upper distillation kettle 41, a driving shaft 42, a transverse groove 43, a square column 44, an extension plate 45 and a rack 46, wherein the upper distillation kettle 41 is fixedly arranged at the bottom end of the inner sleeve 36, a heating resistor is arranged inside the upper distillation kettle 41, a vacuum tube is fixedly arranged on the right side of the upper distillation kettle 41, the driving shaft 42 is rotatably arranged on the inner side of the upper distillation kettle 41 through a bearing, the transverse groove 43 is opened at the bottom end of the driving shaft 42, the square column 44 is fixedly arranged on the top end of the driving shaft 42 and is slidably arranged on the inner side of the square groove 33, the extension plate 45 is fixedly arranged on the top of the front side of the upper distillation kettle 41, and the rack 46 is fixedly arranged on the side of the extension plate 45.

[0026] By setting the above structure, the square column 44 can be driven to rotate through the square groove 33 during the rotation of the reciprocating screw 31, and the transverse groove 43 can be driven to rotate when the square column 44 rotates.

[0027] like Figure 2 As shown, the second driving mechanism 5 includes an outer sleeve plate 51, a column 52, a one-way screw 53, a second spring 54 and a magnet 55, wherein the outer sleeve plate 51 is fixedly sleeved on the outer bottom of the outer sleeve 34, the column 52 is fixedly set on the left side of the bottom of the outer sleeve plate 51, the one-way screw 53 is slidably sleeved on the outside of the column 52, the second spring 54 is fixedly connected between the column 52 and the one-way screw 53, and two magnets 55 are provided. The two magnets 55 are arranged in a vertical direction, one magnet 55 is fixedly set at the bottom end of the one-way screw 53, and the other magnet 55 is fixedly set at the bottom of the inner side of the shell 1.

[0028] By setting the above structure, when the outer sleeve 34 moves downward, the outer sleeve plate 51, the column 52 and the second spring 54 drive the one-way screw 53 to move downward. When the inner sleeve 36 cannot continue to move downward due to obstruction, as the outer sleeve 34 continues to move downward, the first spring 35 is continuously compressed, and at the same time, the outer sleeve plate 51 continues to drive the one-way screw 53 downward through the column 52 and the second spring 54 until the two magnets 55 are attracted to each other. When the outer sleeve 34 is subsequently moved up and reset, the outer sleeve plate 51 drives the column 52 to move upward. At this time, since the two magnets 55 are attracted to each other, the one-way screw 53 cannot rise synchronously. Therefore, the second spring 54 is continuously stretched until it is stretched to an extreme value. Subsequently, as the outer sleeve 34 continues to move upward, the two magnets 55 separate from each other, and the stretched second spring 54 drives the one-way screw 53 to move up and reset.

[0029] like Figure 4As shown, the residue throwing mechanism 6 includes an intermediate plate 61, an annular plate 62, a first gear ring 63, a threaded sleeve 64, a first gear 65, a second gear ring 66 and an L-shaped arm 67, wherein the intermediate plate 61 is fixedly arranged at the middle of the inner side of the housing 1, the annular plate 62 is rotatably arranged at the inner side of the intermediate plate 61 through a bearing, the first gear ring 63 is fixedly sleeved at the outer bottom of the annular plate 62, the threaded sleeve 64 is penetrated and arranged at the left side of the bottom of the intermediate plate 61 and is rotatably connected to the intermediate plate 61 through a bearing, the first gear 65 is sleeved at the outer side of the threaded sleeve 64 through an overrunning clutch and meshes with the first gear ring 63, the second gear ring 66 is rotatably arranged at the inner top of the annular plate 62 through a bearing, and the L-shaped arm 67 is fixedly arranged at the top of the second gear ring 66 and is fixedly connected to the inner wall of the housing 1.

[0030] By setting the above structure, the threaded sleeve 64 can be driven to rotate when the one-way screw 53 moves downward. At this time, due to the limitation of the overrunning clutch, the first gear 65 does not rotate. In the subsequent upward movement of the one-way screw 53, the first gear 65 is driven to rotate through the threaded sleeve 64. During the rotation of the first gear 65, the annular plate 62 is driven to rotate through the first gear ring 63. When the annular plate 62 rotates, the lower distillation mechanism 7 is driven to rotate as a whole.

[0031] like Figure 5 As shown, the lower distillation mechanism 7 includes a lower distillation kettle 71, a rotating shaft 72, a U-shaped scraper 73, a transverse block 74, a second gear 75, a connecting shaft 76, a torsion spring 77 and a third gear 78, wherein the lower distillation kettle 71 is located on the inner side of the annular plate 62 and a heating resistor is arranged inside the annular plate 62, the rotating shaft 72 passes through the lower distillation kettle 71 and is rotatably connected to the lower distillation kettle 71 through a bearing, the U-shaped scraper 73 is fixedly sleeved on the outer side of the rotating shaft 72 and fits with the inner wall of the lower distillation kettle 71, and the transverse block 74 is opened on the rotating shaft 7 2 right end, the second gear 75 is fixedly arranged at the left end of the rotating shaft 72 and meshes with the second gear ring 66, two connecting shafts 76 are provided, and the two connecting shafts 76 are respectively fixedly arranged at the front and back of the lower distillation kettle 71, the connecting shaft 76 passes through the annular plate 62 and is rotatably connected to the annular plate 62 through a bearing, the torsion spring 77 is sleeved on the outside of the connecting shaft 76 and is fixedly connected between the lower distillation kettle 71 and the annular plate 62, and the third gear 78 is sleeved on the outer end of the adjacent connecting shaft 76 through an overrunning clutch.

[0032] By setting the above structure, after the rack 46 is meshed with the third gear 78, as the rack 46 continues to move downward, the rack 46 drives the third gear 78 to rotate, and when the third gear 78 rotates, the lower distillation kettle 71 is driven to gradually rotate from a vertical state to a horizontal state through the connecting shaft 76. In this process, the dehydrated crude oil is added into the lower distillation kettle 71 through the top opening of the lower distillation kettle 71; When the upper still 41 is tightly fitted on the top of the lower still 71, the transverse block 74 is located inside the transverse groove 43. During the rotation of the driving shaft 42, the rotating shaft 72 is driven to rotate continuously through the transverse groove 43 and the transverse block 74. When the rotating shaft 72 rotates, the U-shaped scraper 73 is driven to rotate continuously inside the lower still 71, thereby scraping the inner wall of the lower still 71 and stirring the dehydrated crude oil, so as to improve the distillation efficiency of the dehydrated crude oil. During the subsequent upward movement and reset process of the upper distillation kettle 41, the rack 46 drives the third gear 78 to rotate again. At this time, due to the limitation of the overrunning clutch, the third gear 78 cannot drive the connecting shaft 76 to rotate. Since the lower distillation kettle 71 is detached from the top of the upper distillation kettle 41 and only residues remain inside the lower distillation kettle 71, the torsion spring 77 gradually drives the lower distillation kettle 71 to gradually restore the vertical state after the upper distillation kettle 41 moves upward. After the lower distillation kettle 71 is reset, the top of the second gear 75 engages with the bottom of the second gear ring 66. When the lower distillation mechanism 7 rotates as a whole, the second gear 75 drives the rotating shaft 72 to rotate due to the second gear ring 66. The rotating shaft 72 scrapes off the residue attached to the inner wall of the lower distillation kettle 71 through the U-shaped scraper 73, and then is thrown into the collection tray 2 for collection under the action of the centrifugal force generated when the lower distillation mechanism 7 rotates.

[0033] The method specifically comprises the following steps: S1, start the driving motor 32, the driving motor 32 drives the reciprocating screw 31 to rotate, and the reciprocating screw 31 drives the outer sleeve 34 to move downward when rotating. When the outer sleeve 34 moves downward, the one-way screw 53 is driven downward through the outer sleeve plate 51, the column 52 and the second spring 54, and the inner sleeve 36 is driven downward through the first spring 35. When the one-way screw 53 moves downward, it drives the threaded sleeve 64 to rotate. At this time, due to the limitation of the overrunning clutch, the first gear 65 does not rotate. When the inner sleeve 36 moves downward, it drives the upper distillation mechanism 4 to move downward as a whole. In addition, during the rotation of the reciprocating screw 31, the square column 44 is driven to rotate through the square groove 33. When the square column 44 rotates, it drives the transverse groove 43 to rotate; S2, when the outer sleeve 34 moves downward to a first threshold, the rack 46 meshes with the third gear 78, and when the rack 46 continues to move downward, the rack 46 drives the third gear 78 to rotate, and when the third gear 78 rotates, the lower distillation kettle 71 is driven to gradually rotate from a vertical state to a horizontal state through the connecting shaft 76. In this process, the dehydrated crude oil is added into the lower distillation kettle 71 through the top opening of the lower distillation kettle 71; S3, when the outer sleeve 34 moves downward to a second threshold, the rack 46 is no longer meshed with the third gear 78. At this time, since the lower still 71 is filled with dehydrated wool oil, the lower still 71 cannot be reset under the drive of the torsion spring 77 due to the gravity of the dehydrated wool oil. S4, when the downward movement distance of the outer sleeve 34 reaches the third threshold, the upper distillation kettle 41 is tightly fitted on the top of the lower distillation kettle 71, and the transverse block 74 is located inside the transverse groove 43. During the rotation of the driving shaft 42, the rotating shaft 72 is driven to rotate continuously through the transverse groove 43 and the transverse block 74. When the rotating shaft 72 rotates, the U-shaped scraper 73 is driven to rotate continuously inside the lower distillation kettle 71, thereby scraping the inner wall of the lower distillation kettle 71 and stirring the dehydrated crude oil. S5, start the heating resistors inside the upper distillation kettle 41 and the lower distillation kettle 71 and the vacuum pump connected to the vacuum tube, and then start the distillation and collection of the peppermint oil. At this time, due to the obstruction of the lower distillation kettle 71, the upper distillation kettle 41 cannot continue to move downward, that is, the inner sleeve 36 cannot continue to move downward. Subsequently, as the outer sleeve 34 continues to move downward, the first spring 35 is continuously compressed, and at the same time, the outer sleeve 51 continues to drive the one-way screw 53 to move downward through the column 52 and the second spring 54; S6, when the downward movement distance of the outer sleeve 34 reaches the fourth threshold, the outer sleeve 34 moves to the bottom of the reciprocating thread outside the reciprocating screw 31, and the two magnets 55 are attracted to each other. Subsequently, as the reciprocating screw 31 continues to rotate, the outer sleeve 34 moves upward and resets. During the upward movement of the outer sleeve 34, the compressed first spring 35 is gradually restored, and the column 52 is driven upward through the outer sleeve plate 51. At this time, due to the mutual attraction of the two magnets 55, the one-way screw 53 cannot rise synchronously, so the second spring 54 is continuously stretched; S7, when the upward movement distance of the outer sleeve 34 reaches the fifth threshold, the compressed first spring 35 is restored. When the outer sleeve 34 continues to move upward, the outer sleeve 34 drives the upper distillation kettle 41 to move upward through the first spring 35 and the inner sleeve 36. During the upward movement of the upper distillation kettle 41, the third gear 78 is gradually driven to rotate through the rack 46. At this time, due to the limitation of the overrunning clutch, the third gear 78 cannot drive the connecting shaft 76 to rotate. Since the lower distillation kettle 71 is detached from the top of the upper distillation kettle 41 and only residues remain in the lower distillation kettle 71, the torsion spring 77 gradually drives the lower distillation kettle 71 to gradually restore the vertical state after the upper distillation kettle 41 moves upward. S8, when the upward movement distance of the outer sleeve 34 reaches the sixth threshold, the lower distillation kettle 71 is reset, and at this time, the top of the second gear 75 is meshed with the bottom of the second gear ring 66, and the second spring 54 is stretched to the extreme value. Subsequently, as the outer sleeve 34 continues to move upward, the two magnets 55 separate from each other, and the stretched second spring 54 drives the one-way screw 53 to move upward and reset. During the upward movement of the one-way screw 53, the first gear 65 is driven to rotate through the threaded sleeve 64. During the rotation of the first gear 65, the annular plate 62 is driven to rotate through the first gear ring 63. When the annular plate 62 rotates, the lower distillation mechanism 7 is driven to rotate as a whole. In this process, the second gear 75 drives the rotating shaft 72 to rotate due to the second gear ring 66. The rotating shaft 72 scrapes off the residue attached to the inner wall of the lower distillation kettle 71 through the U-shaped scraper 73, and then is thrown into the collection tray 2 for collection under the action of the centrifugal force generated when the lower distillation mechanism 7 rotates; S9, when the upward movement distance of the outer sleeve 34 reaches the seventh threshold, the outer sleeve 34 arrives at the initial position, that is, the top of the reciprocating thread on the outer side of the reciprocating screw 31, and then as the reciprocating screw 31 continues to rotate, the outer sleeve 34 moves down again.

[0034] It should also be noted that the first threshold, the second threshold, the third threshold and the fourth threshold increase in sequence, and the fifth threshold, the sixth threshold and the seventh threshold increase in sequence. At the same time, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold and the seventh threshold are recorded for the convenience of accurately describing the actual working conditions of the scheme; When the solution of the present application is actually produced, according to the actual specifications of the reciprocating screw 31, the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the fifth threshold value, the sixth threshold value and the seventh threshold value are all specific values.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.

A method for preparing a peppermint oil volatile oil according to claim 6, It is characterized in that The method specifically comprises the following steps: S1, starting the driving motor (32), the driving motor (32) drives the reciprocating screw (31) to rotate, and the reciprocating screw (31) drives the outer sleeve (34) to move downward when rotating. When the outer sleeve (34) moves downward, the one-way screw (53) is driven downward through the outer sleeve plate (51), the column (52) and the second spring (54), and the inner sleeve (36) is driven downward through the first spring (35). When the one-way screw (53) moves downward, the threaded sleeve (64) is driven to rotate. At this time, due to the limitation of the overrunning clutch, the first gear (65) does not rotate. When the inner sleeve (36) moves downward, the upper distillation mechanism (4) is driven to move downward as a whole. In addition, during the rotation of the reciprocating screw (31), the square column (44) is driven to rotate through the square groove (33). When the square column (44) rotates, the transverse groove (43) is driven to rotate; S2, when the downward movement distance of the outer sleeve (34) reaches a first threshold value, the rack (46) meshes with the third gear (78), and when the rack (46) continues to move downward, the rack (46) drives the third gear (78) to rotate, and when the third gear (78) rotates, the lower distillation kettle (71) is driven to gradually rotate from a vertical state to a horizontal state through the connecting shaft (76). During this process, the dehydrated crude oil is added into the lower distillation kettle (71) through the top opening of the lower distillation kettle (71); S3, when the downward movement distance of the outer sleeve (34) reaches the second threshold value, the rack (46) is no longer meshed with the third gear (78). At this time, since the interior of the lower distillation kettle (71) is filled with dehydrated wool oil, the lower distillation kettle (71) cannot be reset under the influence of the gravity of the dehydrated wool oil driven by the torsion spring (77); S4, when the downward movement distance of the outer sleeve (34) reaches the third threshold value, the upper distillation kettle (41) is tightly fitted on the top of the lower distillation kettle (71), and at this time, the transverse block (74) is located inside the transverse groove (43). During the rotation of the driving shaft (42), the rotating shaft (72) is driven to rotate continuously through the transverse groove (43) and the transverse block (74). When the rotating shaft (72) rotates, the U-shaped scraper (73) is driven to rotate continuously inside the lower distillation kettle (71), thereby scraping the inner wall of the lower distillation kettle (71) and stirring the dehydrated crude oil at the same time; S5, starting the heating resistors inside the upper distillation kettle (41) and the lower distillation kettle (71) and the vacuum pump connected to the vacuum tube, and then starting the distillation and collection of the peppermint oil. At this time, due to the obstruction of the lower distillation kettle (71), the upper distillation kettle (41) cannot move downward further, that is, the inner sleeve (36) cannot move downward further. Subsequently, as the outer sleeve (34) continues to move downward, the first spring (35) is continuously compressed, and at the same time, the outer sleeve (51) continues to drive the one-way screw (53) to move downward through the column (52) and the second spring (54); S6, when the downward movement distance of the outer sleeve (34) reaches the fourth threshold value, the outer sleeve (34) moves to the bottom end of the reciprocating thread outside the reciprocating screw (31), and the two magnets (55) are attracted to each other. Subsequently, as the reciprocating screw (31) continues to rotate, the outer sleeve (34) moves upward and resets. During the upward movement of the outer sleeve (34), the compressed first spring (35) is gradually restored, and the column (52) is driven upward through the outer sleeve plate (51). At this time, since the two magnets (55) are attracted to each other, the one-way screw (53) cannot rise synchronously, so the second spring (54) is continuously stretched; S7, when the upward movement distance of the outer sleeve (34) reaches the fifth threshold value, the compressed first spring (35) is restored. When the outer sleeve (34) continues to move upward, the outer sleeve (34) drives the upper distillation kettle (41) to move upward through the first spring (35) and the inner sleeve (36). During the upward movement of the upper distillation kettle (41), the third gear (78) is gradually driven to rotate through the rack (46). At this time, due to the limitation of the overrunning clutch, the third gear (78) cannot drive the connecting shaft (76) to rotate. Since the lower distillation kettle (71) is detached from the top of the upper distillation kettle (41) and only residues remain inside the lower distillation kettle (71), the torsion spring (77) gradually drives the lower distillation kettle (71) to gradually restore the vertical state after the upper distillation kettle (41) moves upward; S8. When the upward movement distance of the outer sleeve (34) reaches the sixth threshold, the lower distillation kettle (71) is reset. At this time, the top of the second gear (75) is meshed with the bottom of the second gear ring (66). At the same time, the second spring (54) is stretched to the extreme value. Subsequently, as the outer sleeve (34) continues to move upward, the two magnets (55) separate from each other, and the stretched second spring (54) drives the one-way screw (53) to move upward and reset. During the upward movement of the one-way screw (53), the first gear (65) is driven to rotate through the threaded sleeve (64). During the rotation of the wheel (65), the annular plate (62) is driven to rotate via the first gear ring (63), and the rotation of the annular plate (62) drives the lower distillation mechanism (7) to rotate as a whole. During this process, the second gear (75) drives the rotating shaft (72) to rotate due to the second gear ring (66), and the rotating shaft (72) scrapes the residue attached to the inner wall of the lower distillation kettle (71) through the U-shaped scraper (73), and then, under the action of the centrifugal force generated by the rotation of the lower distillation mechanism (7), the residue is thrown into the collection plate (2) for collection; S9, when the upward movement distance of the outer sleeve (34) reaches the seventh threshold value, the outer sleeve (34) reaches the initial position, that is, the topmost end of the reciprocating thread on the outer side of the reciprocating screw (31), and subsequently, as the reciprocating screw (31) continues to rotate, the outer sleeve (34) moves downward again.
