DETAILED DESCRIPTION

[0018] like Figure 1-8 As shown, a Chinese medicine extract concentration device includes a support base 4, on which a concentration barrel 1 is arranged, and the height of the concentration barrel 1 on the support base 4 can be automatically adjusted according to the weight of the extract in the barrel. The lower end of the concentration barrel 1 is provided with an adjustable support structure connected to the support base 4, and the adjustable support structure includes a rotating rod 29 that is sealed and rotatably connected to the bottom of the concentration barrel 1. The rotating rod 29 is provided with a plurality of tubular heating components and stirring components whose spacing can be automatically and evenly adjusted according to the weight of the concentration barrel 1. The concentration barrel 1 is also provided with a driving structure that can drive the stirring component to rotate in a circle and flip at the same time.

[0019] When the present invention is used, the Chinese medicine extract is injected into the concentration barrel 1, and the concentration barrel 1 slides down along the support seat 4 due to the increase in weight, the adjustable support structure works, the tubular heating component and the stirring component are equidistantly increased, and the rotating rod 29 drives the tubular heating component and the stirring component to rotate in a circle while the tubular heating component is used to heat the extract in the concentration barrel 1, and the stirring component stirs the heated extract, ensuring that the extract is heated evenly and concentrated by heating. As the solvent in the extract disperses out of the concentration barrel 1, the liquid level of the extract in the concentration barrel 1 drops, the overall weight of the concentration barrel 1 decreases, and the tubular heating component The spacing between the stirring components is adaptively reduced to ensure that the tubular heating component is immersed in the extract to avoid heat waste. As the solvent evaporates, the viscosity of the extract increases and the spacing between the stirring components is reduced, which can improve the stirring effect of the extract. Compared with increasing the stirring speed of the stirring components, it can effectively avoid the problems of breaking the stirring components and splashing of materials. At the same time, the stirring components drive the rotating structure to work while rotating in a circle for stirring. Since the stirring components are cross-arranged, the stirring components rotate on their own while rotating in a circle to achieve upside-down flipping of the inside of the extract, thereby improving the stirring effect.

[0020] The adjustable supporting structure also includes a sliding rod 16 slidably arranged on the inner wall of the rotating rod 29, the lower end of the sliding rod 16 is fixedly connected to a fixed plate 9, and the two ends of the fixed plate 9 are respectively provided with a first slide frame 10, and the two ends of the supporting seat 4 are respectively fixedly provided with a pressing rod 11, and one end of the pressing rod 11 is rotatably connected to a swing rod 13, and the lower end of the swing rod 13 is provided with a first pin rod 14 slidably connected to the inner wall of the first slide frame 10, and the lower ends of the concentration barrel 1 are respectively provided with second slide frames 12 corresponding to the first slide frame 10, and the upper end of the swing rod 13 is provided with a second pin rod 15 slidably connected to the inner wall of the second slide frame 12, and the upper end of the pressing rod 11 is respectively provided with a spring 7 connected to the concentration barrel 1.

[0021] like Figure 2 As shown, initially, the overall weight of the concentration barrel 1 increases, the spring 7 is compressed and expanded, and the concentration barrel 1 descends. During the descent of the concentration barrel 1, the second slide slot frames 12 at both ends are driven to descend respectively. Since the middle limit rotation of the swing rod 13 is set on the pressing rod 11, when the second slide slot frame 12 descends, the swing rod 13 is driven by the second pin rod 15 to swing with the connection with the pressing rod 11 as the axis. When one end of the swing rod 13 is pressed and tends to rotate downward, the other end of the swing rod 13 tends to rotate upward. When the other end of the swing rod 13 rotates upward, the first slide slot frame 10 is driven to move upward through the first pin rod 14. The first slide slot frame 10 simultaneously lifts the solid plate 9 upward, and the solid plate 9 drives the sliding solid rod 16 to slide upward along the inner wall of the rotating column 33. Sliding pin blocks 26 slidably connected to the inner wall of the rotating rod 29 are respectively provided on both sides of the upper end of the sliding fixing rod 16, and the sliding pin blocks 26 are fixedly set on the first slide plate 30 slidably connected to the rotating rod 29, and the lower end of the first slide plate 30 is equidistantly provided with a second slide plate 38 and a fixed plate 36, and the two ends of the first slide plate 30 are respectively rotatably connected to a pair of first struts 22, and the lower ends of the first struts 22 are respectively correspondingly rotatably connected to the second struts 23, and the second struts 23 are cross-rotatably set on the second slide plate 38, and the lower ends of the second struts 23 are respectively correspondingly rotatably connected to the third struts 37, and one end of the third strut 37 is coaxially rotatably set on the fixed plate 36, and the fixed plate 36 is fixedly sleeved on the rotating rod 29.

[0022] like Figure 4 and 6As shown, the sliding rod 16 drives the first slide plate 30 to slide upward along the rotating rod 29 through the sliding pin block 26. During the sliding process, the first slide plate 30 drives the first support rods 22 at both ends to swing toward each other, and the first support rods 22 drive the second support rods 23 to swing toward each other. Since the intersection of the second support rods 23 is rotatably set on the second slide plate 38, and since the fixed plate 36 is fixedly set on the rotating rod 29, and the third support rod 37 on the rotating rod 29 is rotatably connected to the second support rod 23, the first slide plate 30 and the second slide plate 38 move upward at an equal distance. Since the liquid level of the concentration barrel 1 is relatively high at the beginning, the first slide plate 30, the second slide plate 38 and the fixed plate 36 can be evenly distributed in the upper, middle and lower parts of the extract, which can effectively ensure that the tubular heating component heats the concentrated liquid at different positions and the stirring component stirs evenly, thereby improving the concentration effect.

[0023] The driving structure includes a fixed gear 19 fixedly arranged at the top of the upper end of the concentration barrel 1 and coaxially arranged with the rotating rod 29, the fixed gear 19 is meshed with a rotating gear 18, and the rotating gear 18 is provided with a stirring column 17 that can rotate in a circle around the rotating rod 29, the first slide plate 30, the second slide plate 38 and one end of the fixed plate 36 are respectively fixedly connected with an internal block 25, the internal block 25 is provided with a worm 31 sleeved on the stirring column 17, and the stirring column 17 is also provided with a spline 34 corresponding to the worm 31, and the internal block 25 is also rotatably provided with a worm wheel 32 meshing with the worm 31, and the worm wheel 32 is provided with a rotating column 33 rotatably connected to the internal block 25, and one end of the rotating column 33 is provided with the stirring component.

[0024] like Figure 5 and 7 As shown in Figure 8, when the rotating rod 29 rotates, the internal block 25 is driven to rotate through the first slide plate 30, the second slide plate 38 and the fixed plate 36 respectively. The internal block 25 synchronously drives the stirring column 17 to rotate in a circle. During the circular rotation of the stirring column 17, the rotating gear 18 is driven to rotate around the rotating rod 29. The rotating gear 18 is meshed with the fixed gear 19 during the circular rotation, thereby realizing the self-rotation of the rotating gear 18. The rotating gear 18 is used to react on the stirring column 17, so that the stirring column 17 rotates in a circle while rotating in a circle. During the self-rotation of the stirring column 17, the worm 31 in the internal block 25 is driven to rotate respectively. The worm 31 correspondingly drives the worm wheel 32 to rotate. The worm wheel 32 drives the stirring component to rotate through the rotating column 33. The stirring component is used to stir the extract. By arranging a spline 34 corresponding to the worm 31 on the stirring column 17, it can be ensured that the stirring column 17 can normally drive the worm 31 to rotate without affecting the worm 31 sliding along the axial direction of the stirring column 17.

[0025] The stirring member includes stirring rods 24 arranged crosswise, and the stirring rods 24 are arranged at equal distances from each other.

[0026] like Figure 5 As shown, the stirring component also includes a mounting block 35 fixedly mounted on the rotating column 33, and the stirring rod 24 is mounted on the mounting block 35 and is cross-arranged, so that the stirring rod rotates while rotating in a circle, thereby turning the inside of the extract upside down and improving the stirring effect.

[0027] A motor 6 is fixedly disposed at the lower end of the concentration barrel 1 , and a driving bevel gear 27 is fixedly connected to the output end of the motor 6 . The driving bevel gear 27 is meshed with a driven bevel gear 28 , and the driven bevel gear 28 is provided with the rotating rod 29 .

[0028] like Figure 2 and 5 As shown, the motor 6 is working, the output end of the motor 6 drives the active bevel gear 27 to rotate, the active bevel gear 27 drives the driven bevel gear 28 to rotate, and the driven bevel gear 28 drives the rotating rod 29 to rotate.

[0029] The tubular heating component includes a heat-conducting pipe body 21 respectively arranged on the first slide plate 30, the second slide plate 38 and one end of the fixed plate 36, a heating rod is arranged in the heat-conducting pipe body 21, and a deliquescence plate 20 for cleaning the inner wall of the concentration barrel 1 is also arranged at the end of the heat-conducting pipe body 21.

[0030] like Figure 2 and 5 As shown, the heating rod is accommodated in the heat-conducting pipe body 21, and the heat-conducting pipe body 21 is used to protect the heating rod and conduct heat, and also to prevent the heating rod from directly contacting the extract and destroying the components of the extract. The deliquidation plate 20 can be spliced ​​as the first slide plate 30, the second slide plate 38 and the fixed plate 36 approach, and the deliquidation plate 20 can be used to scrape off the extract that is contaminated on the barrel wall after concentration.

[0031] The upper end of the concentration barrel 1 is provided with a liquid injection port 2 and a steam discharge port 3, respectively, and the lower end of the concentration barrel 1 is provided with a liquid discharge port 8.

[0032] like Figure 1 and 2 As shown, the extract can be added into the concentration barrel 1 through the liquid injection port 2, and the steam generated by the solvent during the concentration process of the extract can be dissipated from the steam outlet 3. The extract after concentration can be discharged from the liquid outlet 8, and the liquid injection port 2, the steam outlet 3 and the liquid outlet 8 are all provided with valves for controlling discharge and injection.

[0033] The support seat 4 is also provided with a limiting collar 5 , which is sleeved on the periphery of the concentration barrel 1 and is slidably arranged with the concentration barrel 1 .

[0034] like Figure 1 As shown, the limiting collar 5 can limit the concentration barrel 1 to ensure that the concentration barrel 1 slides up and down along the limiting collar 5 to adapt to the overall weight change of the concentration barrel 1.

[0035] The working process of the present invention is as follows: when the present invention is in use, the Chinese medicine extract is injected into the concentration barrel 1, and the concentration barrel 1 slides down along the support seat 4 due to the increase in weight. Initially, the overall weight of the concentration barrel 1 increases, the spring 7 is compressed and retracted, and the concentration barrel 1 descends. During the descent of the concentration barrel 1, the second slide frames 12 at both ends are respectively driven to descend. Since the middle limit rotation of the swing rod 13 is set on the pressing and rotating rod 11, when the second slide frame 12 descends, the swing rod 13 is driven by the second pin 15 to swing with the connection with the pressing and rotating rod 11 as the axis. When one end of the swing rod 13 is pressed and tends to rotate downward, the other end of the swing rod 13 tends to rotate upward. When the other end of the swing rod 13 rotates upward, the first slide frame 10 is driven by the first pin 14 to move upward. The first slide frame 10 synchronously lifts the fixed plate 9 upward, and the fixed plate 9 drives the sliding fixed rod 16 to slide upward along the inner wall of the rotating column 33. The sliding fixed rod 16 drives the first slide plate 30 to slide upward along the rotating rod 29 through the sliding pin block 26. During the sliding process, a slide plate 30 drives the first support rods 22 at both ends to swing toward each other, and the first support rod 22 drives the second support rod 23 to swing toward each other. Since the intersection of the second support rod 23 is rotatably set on the second slide plate 38, and since the fixed plate 36 is fixedly set on the rotating rod 29, and the third support rod 37 on the rotating rod 29 is rotatably connected to the second support rod 23, the first slide plate 30 and the second slide plate 38 move upward at an equal distance. Since the liquid level of the concentration barrel 1 is relatively high at the beginning, the first slide plate 30, the second slide plate 38 and the fixed plate 36 can be evenly distributed in the upper, middle and lower parts of the extract, which can effectively ensure that the tubular heating component heats the concentrated liquid at different positions. The motor 6 works, and the output end of the motor 6 drives the active bevel gear 27 to rotate, the active bevel gear 27 drives the driven bevel gear 28 to rotate, the driven bevel gear 28 drives the rotating rod 29 to rotate, and the rotating rod 29 drives the stirring component to evenly stir the extract to improve the concentration effect.

[0036] As the solvent in the extract disperses out of the concentration barrel 1, the liquid level of the extract in the concentration barrel 1 drops, the overall weight of the concentration barrel 1 decreases, and the heat-conducting pipe body 21 and the stirring rod 24 adaptively reduce the distance between them to ensure that the heat-conducting pipe body 21 is immersed in the extract to avoid heat waste. As the solvent evaporates, the viscosity of the extract increases, and the distance between the stirring rods 24 is reduced, which can improve the stirring effect of the extract. Compared with increasing the stirring speed of the stirring rod 24, it can effectively avoid the problem of breaking the stirring rod 24 and splashing of materials.

[0037] At the same time, the rotating rod 29 drives the inner block 25 to rotate through the first slide plate 30, the second slide plate 38 and the fixed plate 36 respectively when rotating on its own. The inner block 25 synchronously drives the stirring column 17 to rotate in a circle. The stirring column 17 drives the rotating gear 18 to rotate around the rotating rod 29 during the circular rotation. The rotating gear 18 meshes with the fixed gear 19 during the circular rotation, thereby realizing the self-rotation of the rotating gear 18. The rotating gear 18 reacts on the stirring column 17 to realize the stirring column 17 rotating in a circle while rotating on its own. The stirring column 17 drives the inner block 25 to rotate in a circle while rotating on its own during the self-rotation. The worm 31 in the built-in block 25 rotates, and the worm 31 drives the worm wheel 32 to rotate accordingly. The worm wheel 32 drives the stirring rod 24 to rotate through the rotating column 33, and the stirring rod 24 is used to stir the extract. By arranging a spline 34 corresponding to the worm 31 on the stirring column 17, it can be ensured that the stirring column 17 can normally drive the worm 31 to rotate without affecting the axial sliding of the worm 31 along the stirring column 17. Since the stirring rods 24 are cross-arranged, the stirring rods 24 rotate on themselves while rotating in a circle, thereby realizing the upside-down flipping of the inside of the extract, thereby improving the stirring effect.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
