Description

Technical Field

[0001] The invention relates to the field of chemical production, in particular to a nicotine extraction and separation device for stimulating the release of dopamine. Background Art

[0002] Nicotine, commonly known as nicotine, is an organic compound that exists in Solanaceae plants, especially in tobacco plants. It is one of the main alkaloids in tobacco and can stimulate the central nervous system and heart, producing a series of physiological and psychological effects. When smoking or using tobacco products, nicotine quickly enters the blood circulation through the lungs and then passes to the brain, which is one of the main causes of smoking addiction.

[0003] At present, when extracting nicotine, the tobacco raw material needs to be crushed and then mixed with acid and alkali in sequence. When the acid is heated, the mixed liquid needs to be continuously stirred to finally obtain an alkali-containing material, and then the alkali-containing material is filtered by a filter, and the filtered liquid is transported to a steam distillation tank, and the alkali-containing liquid and water vapor are counter-flowed and fully mixed to obtain nicotine-containing water vapor, and then the nicotine-containing water vapor is transported to a condensation tower for condensation to obtain a nicotine-containing aqueous solution.

[0004] In fact, the alkaline material after acidification and alkalization treatment is often thick, and contains a large amount of residue obtained from tobacco reaction. When it is filtered through a filter, it is not only unable to pass through the filter for further filtration, but also because it has a certain water absorption, after the filtration is completed, the filtered residue will still contain a certain amount of alkaline liquid, resulting in incomplete nicotine extraction. Summary of the invention

[0008] As a further solution of the present invention, the driving assembly includes a driving screw, a transmission nut and a synchronous motor;

[0009] The two ends of the driving screw are rotatably connected to the mounting blocks on the upper end cylinder and the bottom cylinder respectively;

[0011] The synchronous motor is fixedly mounted on a set of mounting blocks, and its output shaft is transmission-connected to one end of a driving screw rod through a coupling.

[0012] As a further solution of the present invention, the bottom ring end face of the truncated cone filter element is provided with an outer ring for being pressed by a rotating ring and a lower pressure ring, and the top ring end face of the truncated cone filter element is provided with an inner ring for being pressed by a support plate and a clamping block.

[0013] As a further solution of the present invention, a placement cavity is provided in the slewing ring for positioning and pressing the lower pressure ring into;

[0014] When the lower pressure ring is positioned and pressed into the placement cavity, the height of the upper edge of the lower pressure ring is not lower than the height of the upper edge of the rotary ring.

[0015] As a further solution of the present invention, the rotary assembly includes a rotary gear ring, a driving gear and a power motor;

[0024] S1. The cone filter element is fixedly installed in the movable cylinder, and the bottom ring end face and the top ring end face of the cone filter element are fixed by the lower pressure ring rotating ring and the support plate pressing block in the movable cylinder.

[0033] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0034] like Figure 1 As shown, in an embodiment of the present invention, a nicotine extraction and separation device for stimulating dopamine release comprises a reactor 1, a filter 2, a distillation tank 3 and a condensation tower 4, wherein the reactor 1 is used to sequentially perform acid and alkali treatment on tobacco raw materials to obtain an alkali-containing material, the filter 2 is installed at the bottom of the reactor 1, and is used to filter the alkali-containing material to obtain an alkali-containing liquid, the distillation tank 3 is installed at the rear end of the filter 2, and is used to perform water distillation on the alkali-containing liquid, and the obtained nicotine-containing water vapor is transported to the condensation tower 4 for condensation, thereby obtaining a nicotine aqueous solution;

[0035] Among them, Figure 2 and Figure 3As shown, the filter 2 includes an upper end tube 21, a filter assembly 22, a bottom tube 23 and a truncated cone filter element 222. The top end surface of the upper end tube 21 is penetrated by a feed pipe 25 connected to the reactor 1. The bottom tube 23 and the upper end tube 21 are fixedly arranged and arranged below the upper end tube 21 for connecting with the interface end of the distillation tank 3. The truncated cone filter element 222 is made of a deformable material. The filter assembly 22 is installed between the upper end tube 21 and the bottom tube 23 for fixing the truncated cone filter element 222. It includes a movable tube 221, a lower pressure ring 224 and a slewing ring 223, wherein the movable tube 221 is slidably installed between the upper end tube 21 and the bottom tube 23, and is driven by the driving assembly 24 to rotate along its own axis. The body moves linearly in the axial direction, the lower pressure ring 224 is rotatably installed at the bottom of the upper end cylinder 21 through the mounting column, the slewing ring 223 is rotatably installed in the movable cylinder 221, and is driven to rotate by the slewing assembly 27 on the movable cylinder 221, and the bottom ring end face of the truncated cone filter element 222 is fixed by the slewing ring 223 and the lower pressure ring 224, a telescopic member is coaxially fixedly installed in the slewing ring 223, and a support plate 225 is installed on the movable end of the telescopic member facing the upper end cylinder 21, and a clamping block 226 is installed on the support plate 225, and the top ring end face of the truncated cone filter element 222 is fixed by the support plate 225 and the clamping block 226, and a cleaning assembly 26 for cleaning its annular inner wall is installed on the upper end cylinder 21;

[0036] Specifically, the reactor 1, the distillation tank 3 and the condensation tower 4 described in the present invention are all existing technologies. Specifically, when designing, the reactor 1 is arranged on the upper side of the filter 2, and the feed pipe 25 on the upper end cylinder 21 of the filter 2 is connected with the discharge port of the reactor 1. The filter 2 of the present invention is designed to be open at the top, and the alkali-containing material treated by the reactor 1 enters the filter 2 from the top of the filter 2, and after being filtered in the filter 2, it is discharged from the bottom of the filter 2 into the distillation tank 3;

[0037] The present invention provides a deformable truncated cone filter element 222. When filtering, the truncated cone filter element 222 is deformed so that the top ring end face of the truncated cone filter element 222 is located at the bottom ring end face of the truncated cone filter element 222. At this time, the truncated cone filter element 222 forms a filterable conical structure. During filtering, the truncated cone filter element 222 can be driven to rotate, thereby improving the filtering efficiency of alkali-containing materials and avoiding the problem that the filtered materials contain more liquid, which affects the filtering quality.

[0038] like Figure 2 and Figure 3As shown, in the embodiment of the present invention, the driving assembly 24 includes a driving screw 241, a transmission nut 242 and a synchronous motor 243. The two ends of the driving screw 241 are rotatably connected with the mounting blocks on the upper end cylinder 21 and the bottom cylinder 23 respectively. The transmission nut 242 is fixedly mounted on the outer side of the movable cylinder 221 and forms a spiral pair transmission with the driving screw 241. The synchronous motor 243 is fixedly mounted on a group of mounting blocks, and its output shaft is transmission-connected with one end of the driving screw 241 through a coupling. In the present invention, a group of driving assemblies 24 are respectively installed on both sides of the filter 2, and the movable cylinder 221 is driven to move linearly by the two groups of the driving assemblies 24.

[0039] Furthermore, when the movable cylinder 221 is linearly driven, the two sets of synchronous motors 243 rotate synchronously, driving the two sets of driving screws 241 to rotate synchronously, and the transmission nut 242 fixedly installed on the outside of the movable cylinder 221 is correspondingly connected to the two sets of driving screws 241 for transmission, driving the movable cylinder 221 to move linearly along its axial direction. In the present invention, when the movable cylinder 221 moves toward the direction close to the upper end cylinder 21, the upper end surface of the movable cylinder 221 is sealed and abutted against the bottom surface of the lower end cylinder. The movable cylinder 221 seals the upper cylinder 21 and the bottom cylinder 23, and filtering can be performed at this time. When it is necessary to replace the cone filter element 222 on the movable cylinder 221 or clean the inside of the movable cylinder 221, when the movable cylinder 221 moves away from the upper cylinder 21, the movable cylinder 221 and the cone filter element 222 therein leak out. At this time, the operator can clean the inside of the movable cylinder 221 and replace the cone filter element 222, etc.

[0040] Of course, in actual design, the two sets of driving components 24 can also be replaced by other components with linear driving capabilities, such as cylinder driving mode and the like.

[0041] Further, if Figure 5As shown, in the embodiment of the present invention, the bottom ring end face of the truncated cone filter element 222 is provided with an outer ring for being pressed by a slewing ring 223 and a lower pressure ring 224, and the top ring end face of the truncated cone filter element 222 is provided with an inner ring for being pressed by a support plate 225 and a pressing block 226. When the truncated cone filter element 222 is replaced, the support plate 225 can be driven by the telescopic member to rise to the limit position, and the pressing block 226 on the support plate 225 can be removed, and the truncated cone filter element 222 can be replaced. After the top ring end face is placed on the support plate 225, the clamping block 226 is fixedly installed on the support plate 225, and cooperates with the support plate 225 to clamp and fix the top ring end face of the conical filter element 222. At this time, the bottom ring end face of the conical filter element 222 is placed on the rotating ring 223. When the movable cylinder 221 is driven to rise by the driving assembly 24, the lower pressure ring 224 located in the upper end cylinder 21 cooperates with the rotating ring 223 to clamp and fix the bottom ring end face of the conical filter element 222.

[0042] like Figure 3 As shown, in the embodiment of the present invention, a placement cavity for positioning and pressing the lower pressure ring 224 is provided inside the swivel ring 223. In the present invention, a swivel ring 227 coaxially fixedly connected with the lower pressure ring 224 is provided inside the end surface of the upper end tube 21. The swivel ring 227 is rotatably mounted on the inner wall of the end surface. When the movable tube 221 slides upward to drive the swivel ring 223 and the lower pressure ring 224 to be pressed tightly, the swivel ring 223 can be rotated at this time, driving the lower pressure ring 224 and the swivel ring 223 to rotate synchronously.

[0043] Furthermore, when the lower pressure ring 224 is positioned and pressed into the placement cavity, the upper edge height of the lower pressure ring 224 is not lower than the upper edge height of the rotating ring 223, thereby avoiding the lower pressure ring 224 from blocking the filter residue during the centrifugal rotation cleaning of the conical filter element 222 and reducing the accumulation of residue between the lower pressure ring 224 and the conical filter element 222.

[0044] like Figure 4 As shown, in the embodiment of the present invention, the rotating assembly 27 includes a rotating ring gear 271, a driving gear 272 and a power motor 273, wherein the rotating ring gear 271 is coaxially mounted on the outer side of the rotating ring 223, the driving gear 272 is rotatably mounted on one end of the movable cylinder 221 and meshed with the rotating ring gear 271, and the power motor 273 is fixedly mounted on the movable cylinder 221, and is used to drive the driving gear 272 to rotate. When the present invention realizes the driving rotation of the rotating ring 223, the driving gear 272 is driven to rotate by the power motor 273, and the driving gear 272 is meshed with the rotating ring gear 271 to drive the rotating ring 223 to rotate;

[0045] In the present invention, a mounting groove for rotatably mounting the slewing ring 223 is provided in the movable cylinder 221, and the rotatable connection between the slewing ring 223 and the mounting groove is sealed by a sealing ring.

[0046] like Figure 4 As shown, in the embodiment of the present invention, the telescopic member is a telescopic rod 29, and the fixed rod body of the telescopic rod 29 is coaxially fixedly installed at the center of the mounting frame 28 at the bottom of the slewing ring 223. The present invention adjusts the position height of the support plate 225 by telescoping the telescopic rod 29, and when the movable cylinder 221 rises to the limit height, the filtering state or cleaning state of the truncated cone filter element 222 can be adjusted by telescoping the telescopic rod 29;

[0047] Of course, in actual design, the telescopic member may also be replaced by other components with linear drive capabilities, such as a screw structure and the like.

[0048] like Figure 1 As shown, in the embodiment of the present invention, the clamping block 226 is detachably mounted on the support plate 225, and the top end face of the clamping block 226 is spherical. The clamping block 226 in the present invention can be fixed by nut rotation or other fixing methods. The present invention does not impose rigid requirements on the fixation of the clamping block 226. At the same time, the present invention reduces the residue of raw materials on the clamping block 226 by designing the top end face of the clamping block 226 to be spherical. Of course, a polygonal structure or the like can also be selected in practice.

[0049] like Figure 1 As shown, in the embodiment of the present invention, the cleaning assembly 26 includes a cleaning ring 262, which is coaxially slidably mounted on the inner wall of the upper end cylinder 21 and driven to move by multiple sets of driving cylinders 261 fixedly mounted on the upper end surface of the upper end cylinder 21. In the present invention, when the filtered material is centrifugally thrown onto the upper inner wall of the upper end cylinder 21 and the movable cylinder 221 by the truncated cone filter element 222, the cleaning ring 262 can be driven downward by the multiple sets of driving cylinders 261 to scrape off the material attached to the inner wall and push the material downward to accumulate;

[0050] Furthermore, an annular cleaning groove for storing filtered impurities is provided on the upper side of the movable cylinder 221. The filtered materials accumulated downward are temporarily stored through the annular cleaning groove, and when the movable cylinder 221 slides downward and leaks out, the operator cleans it.

[0051] In summary, the advantages of the present invention are that the existing nicotine extraction and separation device using water distillation is improved, the reactor 1 is arranged on the upper side of the filter 2, and the filter 2 is designed to be open at the top to communicate with the reactor 1, and the original filter element is replaced with a deformable frustum filter element 222. In actual operation:

[0052] S1. The cone filter element 222 is fixedly installed in the movable cylinder 221, and the bottom ring end face and the top ring end face of the cone filter element 222 are fixed by the lower pressure ring 224, the rotating ring 223, the support plate 225 and the pressing block 226 in the movable cylinder 221. When filtering, the alkali-containing material in the reactor 1 enters the filter 2 through the feed pipe 25 on the upper end cylinder 21, and the cone filter element 222 with the top ring end face facing downward is driven to rotate, so as to realize centrifugal filtration of the alkali-containing material, thereby solving the problem that the alkali-containing material after acidification and alkalization is often not filtered sufficiently when it is filtered through the filter 2;

[0053] S2. After the filtration is completed, the telescopic rod 29 can be extended to drive the pressing block 226 to move upward, and the cone filter element 222 can be turned up, so that the side with the filter residue attached is turned to the upper side. At this time, the filter residue can be removed by driving the cone filter element 222 to rotate centrifugally, and the removed material can be moved downward by the cleaning ring 262 provided on the inner side of the upper end cylinder 21, and the separated filter residue is collected downward into the annular cleaning groove on the upper side of the movable cylinder 221;

[0054] S3. By designing a movable cylinder 221, when it is necessary to replace the conical filter element 222 on the movable cylinder 221 or clean the inside of the movable cylinder 221, when the movable cylinder 221 moves away from the upper cylinder 21, the movable cylinder 221 and the conical filter element 222 therein leak out, making it easier for the operator to perform corresponding operations.

[0055] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
