DETAILED DESCRIPTION

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] See also Figure 1 and Figure 7Now, the Chinese medicinal material solution purification and processing device provided by the present invention is described. The Chinese medicinal material solution purification and processing device comprises a heating kettle and a concentration tank; the heating kettle comprises a stationary outer cylinder 1 and a heating inner cylinder 2, and the heating inner cylinder 2 is rotatably arranged in the stationary outer cylinder 1; the lower end of the heating inner cylinder 2 is provided with an openable flow passage, and the flow passage connects the inner cavity of the heating inner cylinder 2 and the inner cavity of the stationary outer cylinder 1; a conveying pipe 19 is provided at the lower part of the stationary outer cylinder 1; the concentration tank comprises a tank body 22, a gas transmission component and a heating component; the gas transmission component comprises an exhaust pipe 23, and the air inlet of the exhaust pipe 23 is located at the upper part of the tank body 22; the heating component comprises a rotating shaft 47 and a heating mesh plate; the rotating shaft 47 is arranged along the axial direction of the tank body 22, and the rotating shaft 47 is connected to a driving motor; the heating mesh plate is arranged on the outer side of the rotating shaft 47 and rotates synchronously with the rotating shaft 47, the heating mesh plate is connected to a heat source 28, and the heating mesh plate has a plurality of longitudinal mesh holes; the outlet end of the conveying pipe 19 extends to the upper part of the tank body 22 and is located above the heating mesh plate.

[0038] Compared with the prior art, the Chinese medicinal material solution purification and processing device provided by the present invention adopts the principle of flash evaporation, and maintains a negative pressure state in the inner cavity of the tank body 22 of the concentration tank through the exhaust pipe 23; the delivery pipe 19 delivers the liquid in the heating kettle from the delivery pipe 19 to the concentration tank and sprays it into the inner cavity of the concentration tank, and under the action of the pressure difference, the solvent in the medicinal solution evaporates and the medicinal solution is concentrated; on the basis of flash evaporation, a heating screen is added to supplement the temperature of the medicinal solution, so that it heats up and evaporates under a low pressure state, thereby improving the concentration efficiency; in addition, the heating screen is fixed and rotated by means of a rotating shaft 47, so that the heating screen drives the medicinal solution to rotate, reduces the passing speed of the medicinal solution from the heating screen, increases the disturbance of the medicinal solution, and improves the heat exchange and evaporation efficiency of the medicinal solution, thereby ensuring that the time of continuous high temperature of the medicinal solution is reduced during concentration, and reducing the influence on the medicinal properties caused by the continuous high temperature state.

[0039] Specifically, the Chinese medicine is boiled in the heating inner cylinder 2 of the heating kettle to obtain the medicinal liquid, and the medicinal liquid enters the interlayer between the static outer cylinder 1 and the heating inner cylinder 2 through the opened flow passage to achieve heat preservation and static; the medicinal liquid after static enters the delivery pipe 19 to be delivered to the concentration tank for evaporation and concentration. The delivery pipe 19 is provided with a delivery pump body 20 and a discharge pipe 21, and the discharge pipe 21 is provided with an openable discharge valve, which is used to discharge residual liquid or clean the heating kettle.

[0040] The outlet end of the delivery pipe 19 extends to the upper part of the inner cavity of the concentration tank. The outlet end of the delivery pipe 19 is provided with a liquid outlet, and the liquid medicine is discharged from the liquid outlet. A part of the liquid medicine is affected by the negative pressure when it is discharged, and a "flash" phenomenon occurs, turning into steam; the other part of the liquid medicine flows downward until it falls on the heating mesh plate and forms a vortex with the heating mesh plate. The vortex flows while rotating around the rotating shaft 47 and passes through the longitudinal mesh holes of the heating mesh plate, and is heated by the heating mesh plate while flowing.

[0041] The heat source 28 connected to the heating mesh may include a hose coiled at the lower end of the heating mesh, and heat transfer oil is poured into the hose; or an electric heating wire coiled in the interlayer of the heating mesh. The heating mesh is made of metal or ceramic material. After being heated by the heat source 28, the heating mesh acts as a second heat source 28 to heat the liquid medicine. In a negative pressure environment, increasing the temperature of the liquid medicine can further improve the evaporation efficiency of the liquid medicine. The heat source 28 is located at the upper end or lower end or in the interlayer of the heating mesh.

[0042] Optionally, at least two heating screens are provided, and two or more heating screens are arranged at intervals in the longitudinal direction. Two or more heating screens are arranged in parallel.

[0043] In addition, in some possible embodiments, see Figure 1 The heating mesh plate includes a first heating mesh plate 27 and a second heating mesh plate 29; the height of the first heating mesh plate 27 gradually decreases from the middle to the edge; the second heating mesh plate 29 is longitudinally spaced below the first heating mesh plate 27; the height of the second heating mesh plate 29 gradually increases from the middle to the edge; the radial angle between the first heating mesh plate 27 and the second heating mesh plate 29 is consistent with the horizontal plane, and the angle is less than 45°.

[0044] In order to improve the heating efficiency, two heating mesh plates are provided, namely the first heating mesh plate 27 and the second heating mesh plate 29, wherein the height of the first heating mesh plate 27 gradually decreases from the middle to the edge, and the inclined first heating mesh plate 27 can increase its contact area with the liquid medicine, thereby improving the heating effect on the liquid medicine; however, when the liquid medicine passes through the first heating mesh plate 27, it is easily affected by the structure of the first heating mesh plate 27 and has a centrifugal force, and causes more liquid medicine to accumulate at the edge, further slowing down the flow speed of the liquid medicine. After passing through the first heating mesh plate 27, the liquid medicine falls into the upper end of the second heating mesh plate 29. At this time, the liquid medicine not only has a centrifugal force but is also affected by the inclination of the second heating mesh plate 29. The speed of the liquid medicine has an initial velocity perpendicular to the direction of the second heating mesh plate 29 and an initial velocity tangential to the second heating mesh plate 29. While heating the liquid medicine, the second heating mesh plate 29 changes the flow state of the liquid medicine again.

[0045] A high-temperature environment is formed between the first heating mesh plate 27 and the second heating mesh plate 29. In this high-temperature environment, since the distance between the edge of the first heating mesh plate 27 and the edge of the second heating mesh plate 29 is smaller than the distance between the middle of the first heating mesh plate 27 and the middle of the second heating mesh plate 29, in the cavity formed by the two heating mesh plates, the temperature of the edge portion is higher than the temperature of the middle portion. The inclined state of the second heating mesh plate 29 can slow down the accumulation of the medicine solution to the outside under the action of centrifugal force through its own inclination, thereby reducing the temperature gradient in the cavity.

[0046] After the liquid medicine is "flash evaporated" under negative pressure and heated by the heating screen, the solvent in the liquid medicine evaporates, and the concentrated liquid medicine falls to the bottom of the concentration tank until it is discharged after evaporation is completed.

[0047] In some possible embodiments, see Figure 1 The concentration tank also includes an auxiliary evaporation component, including two orifice plates 32 arranged at intervals, and the orifice plates 32 are arc-shaped plates; the opening sides of the two orifice plates 32 are arranged opposite to each other, and a buffer chamber is formed between the two orifice plates 32; the middle part of the orifice plate 32 is connected to the outside of the rotating shaft 47, and the orifice plate 32 is located below the heating mesh plate.

[0048] The two orifice plates 32 are disposed opposite to each other, and the opening side of the upper arc-shaped orifice plate 32 faces downward, and the opening side of the lower arc-shaped orifice plate 32 faces upward.

[0049] The auxiliary evaporation component is located on the arc-shaped orifice plate 32 below the heating mesh plate, and the orifice plate 32 has a plurality of evenly arranged through holes; after passing through the heating mesh plate, the medicine liquid falls on the top of the orifice plate 32. Affected by the arc-shaped orifice plate 32, the medicine liquid increases a centrifugal force while flowing in a spiral direction, and enters the buffer cavity between the two empty circles as it rotates. Inside the buffer cavity, it still flows in a spiral shape and has a centrifugal force. Since the opening of the arc-shaped orifice plate 32 located at the lower end of the buffer cavity faces upward, the medicine liquid passes through the orifice plate 32 at the lower end under the action of the centrifugal force and still flows in a spiral shape.

[0050] The two orifice plates 32 of the auxiliary evaporation component disrupt the flow state of the original water flow through rotation and mesh holes, increase its disturbance, and slow down the flow rate; the flow state in the buffer chamber can be stabilized to reduce the impact effect of the water flow; and after adjusting its flow state, the liquid medicine passes through the orifice plate 32 below again, increasing the disturbance of the liquid medicine and reducing the flow rate of the liquid medicine, thereby extending the duration of the liquid medicine in this temperature state.

[0051] In addition, the heating assembly in the concentration tank also includes an annular heating tube 30 and a heating coil 31; the annular heating tube 30 is attached to the inner wall of the tank body 22 and is located in the circumference of the heating mesh plate; the inner wall of the annular heating tube 30 is provided with a sliding groove that slides with the outer edge of the heating mesh plate and the perforated plate 32; the heating coil 31 is spirally distributed in the interlayer of the annular heating tube 30. The heating coil 31 is added in the interlayer of the annular heating tube 30, and under the action of the annular heating tube 30, the temperature of the upper part of the tank body 22 is maintained.

[0052] The heating coil 31 can be filled with high-temperature heat transfer oil.

[0053] In some possible embodiments, see Figure 1A partition 33 is provided at the lower part of the tank body 22, and the partition 33 divides the inner cavity of the tank body 22 into a concentration cavity and a liquid storage cavity; the partition 33 is funnel-shaped, and a drainage hole 34 is provided in the middle of the partition 33. The concentration cavity and the liquid storage cavity are separated by the partition 33, and a temperature difference is formed by the partition 33. The temperature of the concentration cavity is higher than that of the liquid storage cavity, so that the temperature of the concentrated liquid gradually decreases after entering the liquid storage cavity, and it is prevented from being heated for a long time. The funnel-shaped partition 33 facilitates the collection of the liquid medicine.

[0054] A liquid outlet pipe 38 is provided at the bottom of the liquid storage chamber, and an opening and closing valve is connected to the liquid outlet pipe 38 .

[0055] In some possible embodiments, see Figure 1 The gas delivery assembly includes a pipe joint 25 and a gas delivery pipe; the pipe joint 25 includes an extension section and an elbow, the extension section is connected to the gas outlet of the exhaust pipe 23; the elbow is connected to the free end of the extension section, and the axial direction of the opening of the elbow is horizontal; the gas delivery pipe includes a first gas delivery pipe 36 located at the bottom of the concentration chamber and a second gas delivery pipe 37 located at the bottom of the liquid storage chamber, and the air volume of the first gas delivery pipe 36 is consistent with the air volume of the second gas delivery pipe 37.

[0056] The exhaust pipe 23 includes a main pipe and a branch pipe 24. The main pipe is longitudinally arranged and passes through the top plate of the tank body 22. The branch pipe 24 is located at the top of the tank body 22 and is arranged horizontally. Optionally, the branch pipe 24 adopts an annular pipe body or there are multiple branch pipes 24, and the multiple branch pipes 24 are all connected to the main pipe.

[0057] When the branch pipe 24 adopts an annular tube body, the branch pipe 24 has a plurality of air outlets distributed at intervals. A pipe joint 25 is installed at the air outlet, and the inlet of the extension section of the pipe joint 25 is connected to the air outlet and communicates with the exhaust pipe 23 through the air outlet. Optionally, the air outlet is opened at the lower end of the branch pipe 24, and the extension section of the pipe joint 25 is arranged longitudinally, with its inlet end opening upward and connected to the air outlet of the branch pipe 24, and the lower end of the extension section is connected to an elbow, and the opening direction of the elbow is horizontal.

[0058] The exhaust pipe 23 forms a spiral airflow state with the help of the pipe joint 25, changing the air flow direction in the concentrator. The free end of the elbow is located at the top, causing the airflow in the tank 22 to flow from bottom to top, and the direction of gas flow is opposite to the flow direction of the liquid medicine. The gas collides with the liquid medicine, increasing the contact between the liquid medicine and the gas, and the disturbance state of the liquid medicine, thereby increasing the evaporation rate of the liquid medicine.

[0059] In addition, gas pipes are respectively arranged at the bottom of the concentration chamber and the bottom of the liquid storage chamber of the tank body 22. The two gas pipes are used as gas sources to fill the tank body 22 with gas and cooperate with the exhaust pipe 23 to maintain a stable negative pressure state in the tank body 22. Among them, the first gas pipe 36 and the exhaust pipe 23 are located in the same cavity, and the first gas pipe 36 is located at the bottom of the concentration chamber. The gas entering the concentration chamber from the first gas pipe 36 is extracted from the bottom to the top by the exhaust pipe 23, and at the same time contacts with the liquid medicine during the flow. The second gas pipe 37 is located at the bottom of the liquid storage chamber. When it delivers gas to the liquid storage chamber, it will stir the concentrated liquid medicine in the liquid storage chamber, which can quickly cool the liquid medicine and take away some evaporated water vapor.

[0060] There are multiple first gas pipes 36 and multiple second gas pipes 37, and the outlet directions of the multiple first gas pipes 36 are consistent, and the outlet directions of the multiple second gas pipes 37 are consistent. That is, when there are multiple first gas pipes 36, their outlet directions are distributed in a clockwise or counterclockwise direction; the same is true when there are multiple second gas pipes 37.

[0061] The outlet directions of the first gas pipe 36 and the second gas pipe 37 are both horizontal, but the outlet directions of the first gas pipe 36 and the second gas pipe 37 are opposite to the air inlet direction of the elbow, that is, when the outlet directions of the first gas pipe 36 and the second gas pipe 37 are clockwise, the air inlet of the elbow is arranged counterclockwise; conversely, when the outlet directions of the first gas pipe 36 and the second gas pipe 37 are counterclockwise, the air inlet of the elbow is arranged clockwise, so that the gas always maintains a spiral upward flow state.

[0062] In order to facilitate the gas in the liquid storage chamber to smoothly enter the concentration chamber and maintain the pressure in the tank 22 stable, air holes are opened around the partition 33, and the air hole area 35 is an annular area and is located at the highest point of the partition 33, so that there is no gas dead corner at the upper end of the liquid storage chamber.

[0063] In some possible embodiments, see Figure 1 and Figure 2 The end of the delivery pipe 19 has a volute section 26, and the volute section 26 has a plurality of water outlet holes opened in the horizontal direction, and the water outlet direction of the water outlet holes is opposite to the gas outlet direction of the gas delivery pipe. The cooked high-temperature liquid medicine is output from the volute section 26 of the delivery pipe 19. The volute section 26 includes a straight section 45 coaxially arranged with the delivery pipe 19 and a curved section 46 perpendicular to the straight section 45; the straight section 45 is provided with a plurality of horizontal air holes; the curved section 46 changes the flow direction of the liquid, and at the same time, the inner diameter of the curved section 46 gradually increases and then gradually decreases from the fixed end to the free end, so that the outlet end of the curved section 46 forms a nozzle.

[0064] In some possible embodiments, see Figure 1The inner wall of the heating inner cylinder 2 is provided with a guide rib 13 which is spirally distributed from top to bottom, and a heating element 14 is provided inside the guide rib 13. The upper and lower ends of the cross section of the guide rib 13 both include a horizontal section and an inclined section, and the inclined section is located inside the horizontal section. The heating element 14 can be an electric heating wire or the like.

[0065] During the rotation of the heating inner cylinder 2, the water flow is affected by the guide ribs 13 while rotating. The water flow not only flows in a spiral shape due to the centrifugal force, but also increases the disturbance of the water flow due to the collision between the guide ribs 13 and the water flow, thereby increasing the contact and relative collision between the water flow and the drug, thereby accelerating the dissolution of the drug.

[0066] The specific structure of the guide rib 13 includes a horizontal section and an inclined section. Part of the water flow flows in a spiral along the horizontal section of the guide rib 13, and part of the water flow moves to the inclined section to collide and disturb the water flow in the middle, thereby avoiding uneven mixing of the drug in the solvent after the water flow forms a vortex.

[0067] The thickness corresponding to the inclined section of the guide rib 13 gradually decreases from the outside to the inside along the radial direction of the heating inner cylinder 2 .

[0068] The heating element 14 is arranged in the guide rib 13, and the solvent is heated by means of the guide rib 13, which increases the heating area and improves the temperature balance of the solvent, reduces the temperature difference and ensures that the solvent close to the medicine is heated first.

[0069] Further, such as Figure 1 , Figures 3 to 6 As shown, there is a mounting groove 16 parallel to the guide ribs 13 between two adjacent guide ribs 13, and the width of the mounting groove 16 gradually decreases from the outside to the inside along the radial direction of the heating inner cylinder 2; a medicine bag 12 is movably installed in the mounting groove 16, and flow holes are provided on the side panels of the medicine bag 12. The medicine bag 12 includes a bag body 39 and an openable cover 40.

[0070] The mounting groove 16 is located between the two guide ribs 13. The medicine capsule 12 mounted in the mounting groove 16 can be heated simultaneously on both the upper and lower sides to accelerate the temperature of the medicine in the medicine capsule 12. The medicine is more easily dissolved in a higher temperature environment.

[0071] The mounting groove 16 is engaged with the medicine capsule 12 to facilitate installation and removal of the medicine capsule 12 . The flow holes provided on the side plate of the medicine capsule 12 facilitate the solvent to enter the medicine capsule 12 to dissolve the medicine in the medicine capsule 12 .

[0072] like Figure 3 , Figure 4 As shown, the medicine capsule 12 can be semicircular, and the cover 40 is snap-fitted or interference-fitted with the capsule body 39. The cover 40 of the medicine capsule 12 and the side wall of the capsule body 39 are both provided with flow holes. Figure 5 , Figure 6 As shown, the medicine capsule 12 can be circular, and the cover 40 and the capsule body 39 are threadedly connected. A clamping portion 43 is provided on one side of the medicine capsule 12, and the clamping portion 43 includes a supporting portion and an extension arm, and the extension arm extends into the interior of the mounting groove 16 and is clamped with the mounting groove 16. For ease of installation, the cross-section of the clamping portion 43 is smaller than the cross-section of the mounting groove 16. The two ends of the medicine capsule 12 can be limited by the end clamps 15 to prevent the medicine capsule 12 from falling out of the mounting groove 16.

[0073] In addition, an elastic member 41 and a baffle 42 are provided on the inner side of the cover 40, and the baffle 42 extends into the capsule 39 and slides and fits with the inner wall of the capsule 39. The elastic member 41 uses its own elasticity to press the baffle 42 toward the closed end of the capsule 39, squeeze the medicine to the bottom of the capsule 39, and squeeze out the solvent in the medicine. Optionally, when installing the medicine capsule 12, the cover 40 end of the medicine capsule 12 is facing the lower side of the installation groove 16.

[0074] Optionally, the heating inner cylinder 2 rotates intermittently, and the solvent flows during the rotation, and the pressure of the water flow resists the elastic force of a part of the elastic member 41, and contacts and dissolves the medicine. When the heating inner cylinder 2 stops rotating, the elastic member 41 drives the baffle 42 to squeeze the medicine and squeeze out the solution in the capsule 39.

[0075] The end clamp 15 can be made of a flexible material with a certain elasticity, and it is squeezed and installed into the installation groove 16 based on its deformation.
