Description

Technical Field

[0001] The invention relates to the technical field of liquid medicine concentration equipment, in particular to liquid medicine multi-effect evaporation concentration equipment. Background Art

[0002] Concentration is a very important operation process in the production of traditional Chinese medicine. The primary goal of this process is to increase the concentration of the extract at a low cost and high efficiency while ensuring that the effective ingredients of the extract are not reduced and the toxic components are not increased.

[0003] The Chinese utility model patent document with announcement number CN205199005U discloses a liquid medicine concentration device, including a primary heating tank, a primary evaporation tank, a secondary heating tank, a secondary evaporation tank and a condenser. The primary heating tank, the primary evaporation tank, the secondary heating tank and the secondary evaporation tank are connected in sequence. A condenser is provided on one side of the secondary evaporation tank. A primary gas-liquid separator is provided on a connecting pipe A between the primary evaporation tank and the secondary heating tank; a secondary gas-liquid separator is provided on a connecting pipe B between the secondary evaporation tank and the condenser; a liquid receiving tank is provided below the condenser through a cooler, an emptying pipe is provided on the liquid receiving tank, a buffer tank is provided on one side of the liquid receiving tank, the buffer tank is connected to the connecting pipe B through a connecting pipe A, and the buffer tank is connected to the secondary heating tank through a connecting pipe B.

[0004] In the process of circulating and concentrating the drug liquid in the primary heating tank and the secondary heating tank, when the concentration of the drug liquid reaches a certain level, the drug content inside the circulating and concentrated drug liquid will be effectively increased under the same volume compared with the drug liquid in the initial state. Since the concentration of the circulating and concentrated drug liquid increases, the drug content increases. Therefore, the drug liquid at this time will settle at the bottom of the primary heating tank and the secondary heating tank, and cannot continue to participate in the circulating concentration between the primary heating tank and the primary evaporation tank, and between the secondary heating tank and the secondary evaporation tank, which will cause the circulating and concentrated drug liquid to be unable to be further circulated and concentrated.

[0005] Based on this, a liquid medicine multi-effect evaporation concentration equipment is proposed. Summary of the invention

[0006] 1. Technical issues to be resolved

[0007] In view of the shortcomings of the prior art, the present invention provides a liquid medicine multi-effect evaporation concentration device to solve the problems raised in the background technology:

Since the concentration of the circulating and concentrated drug liquid increases, the drug content increases. Therefore, the drug liquid at this time will settle at the bottom of the primary heating tank and the secondary heating tank, and cannot continue to participate in the circulating concentration between the primary heating tank and the primary evaporation tank, and between the secondary heating tank and the secondary evaporation tank, which will lead to the problem that the circulating and concentrated drug liquid cannot be further circulated and concentrated.

[0053] (III) Beneficial effects

[0054] The present invention provides a liquid medicine multi-effect evaporation concentration device, which has the following beneficial effects:

[0055] 1. In the present invention, the driving member can make the active drug lifting stirring mechanism rotate in the inner cavity of the primary heating tank. When the active drug lifting stirring mechanism rotates, the drug liquid in the inner cavity of the primary heating tank can be lifted upward. During the lifting process, the drug liquid is constantly in contact with the steam in the inner cavity of the primary heating tank, so that the drug liquid is concentrated by the steam during the lifting process. When the drug liquid in the primary heating tank is lifted upward, it will fall downward from the outside, thereby promoting the circulation of the drug liquid. Moreover, when the active drug lifting stirring mechanism rotates, it can also stir the drug liquid at the bottom of the inner cavity of the primary heating tank, so that the drugs in the drug liquid are mixed more evenly.

[0056] The rotation of the active drug lifting stirring mechanism can make the driven drug lifting stirring mechanism rotate synchronously through the transmission mechanism. When the driven drug lifting stirring mechanism rotates, the drug liquid in the inner cavity of the secondary heating tank can be lifted upward. During the lifting process, the drug liquid is constantly in contact with the steam in the inner cavity of the secondary heating tank, so that the drug liquid is concentrated by the steam during the lifting process. When the drug liquid in the secondary heating tank is lifted upward, it will fall downward from the outside, thereby promoting the circulation of the drug liquid. Moreover, when the driven drug lifting stirring mechanism rotates, it can also stir the drug liquid at the bottom of the inner cavity of the secondary heating tank, so that the drugs in the drug liquid are mixed more evenly.

[0057] When the driving member drives the active drug lifting type stirring mechanism, and the active drug lifting type stirring mechanism and the driven drug lifting type stirring mechanism work synchronously through the transmission of the transmission mechanism, the concentrated drug liquid can be effectively further concentrated, so that the drug content per unit volume of the drug liquid is further increased on the basis of the original concentration, and the drug content per unit volume can also be more uniform.

[0058] Second, in the present invention, the reduction motor can drive the rotation of the first linkage rod through its output shaft, and the first linkage rod can drive the rotation of the active shaft. When the active shaft is rotating, not only the first spiral lifting blade can be rotated, but also the first stirring member can be rotated synchronously;

[0059] When the first spiral lifting blade rotates, the medicine liquid in the inner cavity of the first-level heating tank can be lifted upward, and when the first stirring member rotates synchronously, the medicine liquid at the bottom of the inner cavity of the first-level heating tank can be fully stirred.

[0060] When the first linkage rod rotates with the output shaft of the reduction motor, the driving pulley also rotates with the first linkage rod. The rotation of the driving pulley can make the driven pulley rotate synchronously through the transmission action of the transmission mechanism. The rotation of the driven pulley can drive the rotation of the second linkage rod. The rotation of the second linkage rod can drive the rotation of the driven shaft. When the driven shaft rotates, not only the second spiral lifting blade can be rotated, but also the second stirring member can be rotated synchronously.

[0061] When the second spiral lifting blade rotates, the medicine liquid in the inner cavity of the secondary heating tank can be lifted upward, and when the second stirring member rotates synchronously, the medicine liquid at the bottom of the inner cavity of the secondary heating tank can be fully stirred.

[0062] 3. In the present invention, an annular space is formed between the first-level heating tank and the first spiral lifting blade, and between the second-level heating tank and the second spiral lifting blade. The liquid medicine lifted upward by the first spiral lifting blade and the liquid medicine lifted upward by the second spiral lifting blade can pass through the corresponding annular space and fall downward during the lifting process, thereby promoting the circulation of the liquid medicine in the first-level heating tank and the second-level heating tank.

[0063] Fourth, in the present invention, the first fixing ring can rotate synchronously with the rotation of the driving shaft. When the first fixing ring rotates, the plurality of first stirring rods can realize synchronous rotation. While the plurality of first stirring rods rotate, the liquid medicine at the bottom of the inner cavity of the first-stage heating tank can be stirred and mixed;

[0064] The second fixed ring can rotate synchronously with the rotation of the driven shaft. When the second fixed ring rotates, the multiple second stirring rods can rotate synchronously. While rotating, the multiple second stirring rods can stir and mix the medicine liquid at the bottom of the inner cavity of the secondary heating tank.

[0065] 5. In the present invention, the rotation of the first linkage rod can drive the rotation of the driving pulley, and the rotation of the driving pulley can make the first transmission belt synchronously transmitted. When the first transmission belt is transmitted, it can drive the rotation of the transmission component, and the rotation of the transmission component can make the second transmission belt synchronously transmitted. When the second transmission belt is transmitted, it can drive the rotation of the driven pulley, and the rotation of the driven pulley can drive the rotation of the second linkage rod, so that through the transmission action of the transmission mechanism, the active drug lifting type stirring mechanism and the driven drug lifting type stirring mechanism can move synchronously.

[0066] 6. In the present invention, when the first transmission belt is transmitting, it can drive the rotation of the first transmission pulley, and the rotation of the first transmission pulley can drive the rotation of the transmission rod. When the transmission rod rotates, it can drive the rotation of the second transmission pulley. When the second transmission pulley rotates, it can make the second transmission belt transmit.

[0079] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0080] Embodiment 1

[0081] The Chinese utility model patent document with announcement number CN205199005U discloses a drug liquid concentrating device. However, during the process of circulating and concentrating the drug liquid in the primary heating tank and the secondary heating tank, when the concentration of the drug liquid reaches a certain level, compared with the drug liquid in the initial state, at the same volume, the drug content inside the circulating and concentrated drug liquid will be effectively increased. Since the concentration of the circulating and concentrated drug liquid increases, the drug content increases. Therefore, the drug liquid at this time will settle at the bottom of the primary heating tank and the secondary heating tank, and cannot continue to participate in the circulating concentration between the primary heating tank and the primary evaporation tank, and between the secondary heating tank and the secondary evaporation tank, which will cause the circulating and concentrated drug liquid to be unable to be further circulated and concentrated.

[0082] Based on this, in order to solve the above technical problems, the R&D personnel have adopted the following technical solutions, as follows:

[0083] like Figure 1-11 As shown, the present invention provides a technical solution:

[0084] A liquid medicine multi-effect evaporation concentration device, comprising:

[0085] A primary heating tank 10, in which the liquid medicine to be concentrated is contained;

[0086] A primary evaporation tank 20 is disposed on one side of the primary heating tank 10, and the bottom of the primary evaporation tank 20 corresponds to the top of the primary heating tank 10;

[0087] The secondary heating tank 30, which contains the liquid medicine to be concentrated, is arranged on one side of the primary evaporation tank 20, and the top of the secondary heating tank 30 corresponds to the bottom of the primary evaporation tank 20;

[0088] A secondary evaporation tank 40 is disposed on one side of the secondary heating tank 30, and the bottom of the secondary evaporation tank 40 corresponds to the top of the secondary heating tank 30;

[0089] The first-stage heating tank 10, the first-stage evaporation tank 20, the second-stage heating tank 30 and the second-stage evaporation tank 40 are arranged in an up-and-down staggered manner;

[0090] A cooling tank assembly 50, which is disposed on one side of the secondary evaporation tank 40;

[0091] A primary gas-liquid separation structure 60 is disposed above the primary evaporation tank 20 and the secondary heating tank 30, one end of the primary gas-liquid separation structure 60 is connected to the primary evaporation tank 20, and the other end of the primary gas-liquid separation structure 60 is connected to the secondary heating tank 30;

[0092] A secondary gas-liquid separation structure 70 is disposed above the secondary evaporation tank 40 and the cooling tank assembly 50, one end of the secondary gas-liquid separation structure 70 is connected to the secondary evaporation tank 40, and the other end of the secondary gas-liquid separation structure 70 is connected to the cooling tank assembly 50;

[0093] A pipeline structure installed between the primary heating tank 10, the primary evaporation tank 20, the secondary heating tank 30 and the secondary evaporation tank 40;

[0094] A driving member 80, which is disposed above the top of the primary heating tank 10;

[0095] An active drug lifting stirring mechanism 90 is installed in the inner cavity of the primary heating tank 10. One end of the active drug lifting stirring mechanism 90 passes through the top of the primary heating tank 10 upwards and is connected to the driving member 80.

[0096] A driven drug lifting type stirring mechanism 100 is installed in the inner cavity of the secondary heating tank 30, and one end of the driven drug lifting type stirring mechanism 100 passes through the top of the secondary heating tank 30 and extends upward; and

[0097] The transmission mechanism 110 has one end connected to the active drug lifting stirring mechanism 90, the other end connected to the passive drug lifting stirring mechanism 100, and one side of the middle part connected to the primary evaporation tank 20;

[0098] The driving member 80 can make the active drug lifting type stirring mechanism 90 rotate in the inner cavity of the primary heating tank 10, and during the rotation of the active drug lifting type stirring mechanism 90, the driven drug lifting type stirring mechanism 100 can be synchronously rotated in the inner cavity of the secondary heating tank 30 through the transmission mechanism 110, so that the drug liquid in the primary heating tank 10 and the secondary heating tank 30 can be repeatedly circulated and concentrated.

[0099] In this embodiment, when the drug liquid concentration device is working, steam enters the primary heating tank 10 to heat the drug liquid. The drug liquid is converted from liquid to gas under the action of steam heating, that is, the drug liquid is vaporized. Under the action of vacuum, the vaporized drug liquid enters the primary evaporation tank 20 from the pipeline structure. After entering the primary evaporation tank 20, due to contact with the inner wall of the primary evaporation tank 20, the vaporized drug liquid is converted from gas to liquid again. The liquefied drug liquid is attached to the inner wall of the primary evaporation tank 20 and flows downward along the inner wall of the primary evaporation tank 20. At this time, the drug liquid flowing downward along the inner wall of the primary evaporation tank 20 flows back from the pipeline structure to the primary heating tank 10. After the drug liquid in the primary heating tank 10 is heated again, it enters the primary evaporation tank 20 to form a cycle, and the concentration is repeated in this way.

[0100] In this process, the vaporized liquid medicine enters the primary evaporation tank 20 to form mist, and the water is rapidly evaporated. The evaporated steam passes through the primary gas-liquid separation structure 60 to achieve gas-liquid separation, so that the liquid medicine flows back to the primary evaporation tank 20, and then flows back to the primary heating tank 10 through the pipeline structure. At the same time, the separated steam enters the secondary heating tank 30 and merges with the steam in the secondary heating tank 30, thereby realizing the reuse of steam.

[0101] In addition, after the liquid medicine in the secondary heating tank 30 is heated by steam, it is converted from liquid to gas, that is, in the vaporization process of the liquid medicine, under the action of vacuum, the vaporized liquid medicine enters the secondary evaporation tank 40 from the pipeline structure. After entering the secondary evaporation tank 40, due to contact with the inner wall of the secondary evaporation tank 40, the vaporized liquid medicine will be converted from gas to liquid again. The liquefied liquid medicine will adhere to the inner wall of the secondary evaporation tank 40 and flow downward along the inner wall of the secondary evaporation tank 40. At this time, the liquid medicine flowing downward along the inner wall of the secondary evaporation tank 40 will flow back to the secondary heating tank 30 from the pipeline structure. After the liquid medicine in the secondary heating tank 30 is heated again, it will enter the secondary evaporation tank 40 again to form a cycle, and the concentration will be repeated in this way.

[0102] In this process, the vaporized medicine liquid enters the secondary evaporation tank 40 to form mist, and the water is rapidly evaporated. The evaporated steam passes through the secondary gas-liquid separation structure 70 to achieve gas-liquid separation, so that the liquid medicine liquid flows back to the secondary evaporation tank 40, and then flows back to the secondary heating tank 30 through the pipeline structure. At the same time, the separated steam enters the cooling tank assembly 50 and condenses into water and is discharged. This cycle is repeated until the water in the medicine liquid is continuously evaporated to increase the concentration of the medicine liquid.

[0103] When the concentration of the drug liquid reaches a certain level during the circulation and concentration process, compared with the drug liquid in the initial state, under the same volume, the drug content inside the circulating and concentrated drug liquid will be effectively increased. Since the concentration of the circulating and concentrated drug liquid increases, the drug content increases. Therefore, the drug liquid at this time will settle at the bottom of the primary heating tank 10 and the secondary heating tank 30, and cannot continue to participate in the circulation and concentration between the primary heating tank 10 and the primary evaporation tank 20, and the secondary heating tank 30 and the secondary evaporation tank 40. In order to enable the concentrated drug liquid to be further circulated and concentrated to further increase the drug content in the drug liquid per unit volume, the research and development personnel start the driving member 80 at this time. The driving member 80 can make the active drug lifting stirring mechanism 90 rotate in the inner cavity of the primary heating tank 10. When the active drug lifting stirring mechanism 90 rotates, the drug liquid in the inner cavity of the primary heating tank 10 can be lifted upward. During the lifting process, the drug liquid is constantly in contact with the steam in the inner cavity of the primary heating tank 10, so that the drug liquid is concentrated by the steam during the lifting process. After the drug liquid in the primary heating tank 10 is lifted upward, it will fall downward from the outside, thereby promoting the circulation of the drug liquid. Moreover, when the active drug lifting stirring mechanism 90 rotates, it can also stir the drug liquid at the bottom of the inner cavity of the primary heating tank 10, so that the drugs in the drug liquid are mixed more evenly.

[0104] The rotation of the active drug lifting stirring mechanism 90 can make the driven drug lifting stirring mechanism 100 rotate synchronously through the transmission mechanism 110. When the driven drug lifting stirring mechanism 100 rotates, the drug liquid in the inner cavity of the secondary heating tank 30 can be lifted upward. During the lifting process, the drug liquid is constantly in contact with the steam in the inner cavity of the secondary heating tank 30, so that the drug liquid is concentrated by the steam during the lifting process. After the drug liquid in the secondary heating tank 30 is lifted upward, it will fall downward from the outside, thereby promoting the circulation of the drug liquid. Moreover, when the driven drug lifting stirring mechanism 100 rotates, it can also stir the drug liquid at the bottom of the inner cavity of the secondary heating tank 30, so that the drugs in the drug liquid are mixed more evenly.

[0105] When the driving member 80 drives the active drug lifting type stirring mechanism 90, and the active drug lifting type stirring mechanism 90 and the driven drug lifting type stirring mechanism 100 work synchronously through the transmission of the transmission mechanism 110, the concentrated drug solution can be further concentrated effectively, so that the drug content per unit volume of the drug solution is further increased on the basis of the original concentration, and the drug content per unit volume can also be more uniform.

[0106] Embodiment 2

[0107] like Figure 1-11 As shown, based on the first embodiment, the following improvements are made:

[0108] Furthermore, the pipeline structure includes a connecting pipe A120 connecting between the top of the side wall of the primary heating tank 10 and the bottom of the side wall of the primary evaporation tank 20, a connecting pipe B130 connecting between the bottom of the side wall of the primary heating tank 10 and the bottom of the primary evaporation tank 20, a connecting pipe C140 connecting between the top of the side wall of the secondary heating tank 30 and the bottom of the side wall of the secondary evaporation tank 40, and a connecting pipe D150 connecting between the bottom of the side wall of the secondary heating tank 30 and the bottom of the secondary evaporation tank 40.

[0109] The connecting pipe A120 and the connecting pipe C140 are in a straight line, and the connecting pipe B130 and the connecting pipe D150 are in an L shape.

[0110] In this embodiment, the liquid medicine in the primary heating tank 10 can be repeatedly circulated and concentrated among the primary heating tank 10, the primary evaporation tank 20, the connecting pipe A120 and the connecting pipe B130, and the liquid medicine in the secondary heating tank 30 can be repeatedly circulated and concentrated among the secondary heating tank 30, the secondary evaporation tank 40, the connecting pipe C140 and the connecting pipe D150.

[0111] Specifically, steam enters the primary heating tank 10 to heat the medicinal liquid, and the medicinal liquid is converted from liquid to gas under the action of steam heating, that is, the vaporization process of the medicinal liquid. Under the action of vacuum, the vaporized medicinal liquid will enter the primary evaporation tank 20 upward through the connecting pipe A120. When the vaporized medicinal liquid enters the primary evaporation tank 20, due to the contact with the inner wall of the primary evaporation tank 20, the vaporized medicinal liquid will be converted from gas to liquid again. The liquefied medicinal liquid will adhere to the inner wall of the primary evaporation tank 20 and flow downward along the inner wall of the primary evaporation tank 20. At this time, the medicinal liquid flowing downward along the inner wall of the primary evaporation tank 20 will flow back to the primary heating tank 10 through the connecting pipe B130. After the medicinal liquid in the primary heating tank 10 is heated again, it will enter the primary evaporation tank 20 to form a cycle, and the concentration will be repeated in this way.

[0112] The primary gas-liquid separation structure 60 can separate the steam in the primary evaporation tank 20 into gas and liquid, and the separated steam is transported to the secondary heating tank 30. The separated liquid medicine will continue to flow downward along the inner wall of the primary evaporation tank 20 and flow into the primary heating tank 10 through the connecting pipe B130.

[0113] The steam transported to the secondary heating tank 30 merges with the original steam in the secondary heating tank 30 to circulate and heat the liquid medicine in the secondary heating tank 30. At this time, the liquid medicine in the secondary heating tank 30 will be converted from liquid to gas under the action of steam heating, that is, the vaporization process of the liquid medicine. Under the action of vacuum, the vaporized liquid medicine will pass through the connecting pipe C140 and enter the secondary evaporation tank 40 upward. When the vaporized liquid medicine enters the secondary evaporation tank 40, it will contact with the inner wall of the secondary evaporation tank 40. Therefore, the vaporized liquid medicine will be converted from gas to liquid again. The liquefied liquid medicine will adhere to the inner wall of the secondary evaporation tank 40 and flow downward along the inner wall of the secondary evaporation tank 40. At this time, the liquid medicine flowing downward along the inner wall of the secondary evaporation tank 40 will flow back to the secondary heating tank 30 through the connecting pipe D150. After the liquid medicine in the secondary heating tank 30 is heated again, it will enter the secondary evaporation tank 40 to form a cycle, and the concentration will be repeated in this way.

[0114] The secondary gas-liquid separation structure 70 can separate the steam in the secondary evaporation tank 40 into gas and liquid. The separated steam is transported to the cooling tank assembly 50. The separated liquid medicine will continue to flow downward along the inner wall of the secondary evaporation tank 40 and flow into the primary heating tank 10 through the connecting pipe D150.

When the second fixed ring 10041 rotates, the multiple second stirring rods 10042 can rotate synchronously. While rotating, the multiple second stirring rods 10042 can stir and mix the medicine liquid at the bottom of the inner cavity of the secondary heating tank 30.

[0150] In order to optimize the specific structure of the transmission mechanism 110, the researchers further provided that in this embodiment, the transmission mechanism 110 includes a transmission component 1103 installed on the side wall of the primary evaporation tank 20, and the transmission component 1103 is respectively installed with a first transmission belt 1101 and a second transmission belt 1102;

[0159] Embodiment 5

[0160] like Figure 1-11 As shown, based on the first embodiment, the following improvements are made:

[0162] The condenser 501, cooler 502, liquid receiving tank 503 and drain pipe 504 in the present application all adopt the existing technology, so the structures of the condenser 501, cooler 502, liquid receiving tank 503 and drain pipe 504 will not be described in detail.

[0163] In this embodiment, the cooling tank assembly 50 is used to condense and liquefy the steam, and the liquefied water is discharged to the outside through the drain pipe 504.

[0164] Embodiment 6

[0165] like Figure 1-11 As shown, it is improved on the basis of Example 5:

[0166] In order to optimize the specific structures of the primary gas-liquid separation structure 60 and the secondary gas-liquid separation structure 70, the researchers further, in this embodiment, the primary gas-liquid separation structure 60 includes a first gas-liquid separator 601, the first gas-liquid separator 601 is arranged above the primary evaporation tank 20 and the secondary heating tank 30, the feed end of the first gas-liquid separator 601 is connected with a pumping pipe A602, the pumping pipe A602 is connected to the top of the primary evaporation tank 20 at one end away from the first gas-liquid separator 601, the discharge end of the first gas-liquid separator 601 is connected with a delivery pipe A603, the delivery pipe A603 is connected to the top of the secondary heating tank 30 at one end away from the first gas-liquid separator 601;

[0167] The secondary gas-liquid separation structure 70 includes a second gas-liquid separator 701, which is arranged above the secondary evaporation tank 40 and the condenser 501. The feed end of the second gas-liquid separator 701 is connected to a pumping pipe B702, and the pumping pipe B702 is connected to the top of the secondary evaporation tank 40 at the end away from the second gas-liquid separator 701. The discharge end of the pumping pipe B702 is connected to a delivery pipe B703, and the delivery pipe B703 is connected to the upper part of the side wall of the condenser 501 at the end away from the second gas-liquid separator 701.

[0168] In this embodiment, the first gas-liquid separator 601 can separate the steam in the primary evaporation tank 20 into gas and liquid, and the second gas-liquid separator 701 can separate the steam in the secondary evaporation tank 40 into gas and liquid. Specifically, when the first gas-liquid separator 601 is working, the steam circulating in the primary evaporation tank 20 is extracted through the extraction pipe A602, and the separated steam is transported to the secondary heating tank 30 through the delivery pipe A603, so that the steam in the primary evaporation tank 20 is combined with the steam in the secondary heating tank 30, so as to improve the utilization rate of the steam.

[0169] Since the first gas-liquid separator 601 can perform gas-liquid separation, the liquid medicine mixed in the steam will be separated by the first gas-liquid separator 601 and retained in the material extraction pipe A602. The liquid medicine will flow downward along the inner wall of the material extraction pipe A602 into the primary evaporation tank 20.

[0170] When the second gas-liquid separator 701 is in operation, the steam circulating in the secondary evaporation tank 40 is extracted through the extraction pipe B702, and the separated steam is transported to the condenser 501 through the delivery pipe B703, and the steam is condensed and liquefied through the cooling tank assembly 50;

[0171] Since the second gas-liquid separator 701 can perform gas-liquid separation, the liquid medicine mixed in the steam will be separated by the second gas-liquid separator 701 and retained in the extraction pipe B702. The liquid medicine will flow downward along the inner wall of the extraction pipe B702 into the secondary evaporation tank 40.

[0172] In summary, the workflow of the present invention is:

[0173] like Figure 1-11 As shown, when the drug liquid concentration device is working, steam enters the primary heating tank 10 to heat the drug liquid, and the drug liquid is converted from liquid to gas under the action of steam heating, that is, in the vaporization process of the drug liquid, under the action of vacuum, the vaporized drug liquid enters the primary evaporation tank 20 from the pipeline structure, and after entering the primary evaporation tank 20, it is converted from gas to liquid, and the drug liquid flows back from the pipeline structure to the primary heating tank 10, and the drug liquid in the primary heating tank 10 is heated again and enters the primary evaporation tank 20 to form a cycle, and the concentration is repeated in this way;

[0174] In this process, the vaporized liquid medicine enters the primary evaporation tank 20 to form mist, and the water is rapidly evaporated. The evaporated steam passes through the primary gas-liquid separation structure 60 to achieve gas-liquid separation, so that the liquid medicine flows back to the primary evaporation tank 20, and then flows back to the primary heating tank 10 through the pipeline structure. At the same time, the separated steam enters the secondary heating tank 30 and merges with the steam in the secondary heating tank 30, thereby realizing the reuse of steam.

[0175] Moreover, after the liquid medicine in the secondary heating tank 30 is heated by steam, it is converted from liquid to gas, that is, in the vaporization process of the liquid medicine, under the action of vacuum, the vaporized liquid medicine enters the secondary evaporation tank 40 from the pipeline structure, and after entering the secondary evaporation tank 40, it is converted from gas to liquid, and the liquid medicine flows back to the secondary heating tank 30 from the pipeline structure, and the liquid medicine in the secondary heating tank 30 is heated again and enters the secondary evaporation tank 40 to form a cycle, and the concentration is repeated in this way;

[0176] In this process, the vaporized medicine liquid enters the secondary evaporation tank 40 to form mist, and the water is rapidly evaporated. The evaporated steam passes through the secondary gas-liquid separation structure 70 to achieve gas-liquid separation, so that the liquid medicine liquid flows back to the secondary evaporation tank 40, and then flows back to the secondary heating tank 30 through the pipeline structure. At the same time, the separated steam enters the cooling tank assembly 50 and condenses into water and is discharged. This cycle is repeated until the water in the medicine liquid is continuously evaporated to increase the concentration of the medicine liquid.

[0177] When the concentration of the drug liquid reaches a certain level during the circulation and concentration process, the drug content in the circulating and concentrated drug liquid will be effectively increased compared to the drug liquid in the initial state at the same volume. Since the concentration of the circulating and concentrated drug liquid increases, the drug content increases. Therefore, the drug liquid at this time will settle at the bottom of the primary heating tank 10 and the secondary heating tank 30, and cannot continue to participate in the circulation and concentration between the primary heating tank 10 and the primary evaporation tank 20, and the secondary heating tank 30 and the secondary evaporation tank 40. In order to enable the concentrated drug liquid to be further circulated and concentrated to further increase the drug content in the drug liquid per unit volume, the R&D personnel at this time move the driving member 80 When started, the driving member 80 can make the active drug lifting stirring mechanism 90 rotate in the inner cavity of the primary heating tank 10. When the active drug lifting stirring mechanism 90 rotates, the drug liquid in the inner cavity of the primary heating tank 10 can be lifted upward. During the lifting process, the drug liquid is constantly in contact with the steam in the inner cavity of the primary heating tank 10, so that the drug liquid is concentrated by the steam during the lifting process. When the drug liquid in the primary heating tank 10 is lifted upward, it will fall downward from the outside to promote the circulation of the drug liquid. Moreover, when the active drug lifting stirring mechanism 90 rotates, it can also stir the drug liquid at the bottom of the inner cavity of the primary heating tank 10 to make the mixing of the drugs in the drug liquid more uniform.

[0178] The rotation of the active drug lifting stirring mechanism 90 can make the driven drug lifting stirring mechanism 100 rotate synchronously through the transmission mechanism 110. When the driven drug lifting stirring mechanism 100 rotates, the drug liquid in the inner cavity of the secondary heating tank 30 can be lifted upward. During the lifting process, the drug liquid is constantly in contact with the steam in the inner cavity of the secondary heating tank 30, so that the drug liquid is concentrated by the steam during the lifting process. When the drug liquid in the secondary heating tank 30 is lifted upward, it will fall downward from the outside to promote the circulation of the drug liquid. Moreover, when the driven drug lifting stirring mechanism 100 rotates, it can also stir the drug liquid at the bottom of the inner cavity of the secondary heating tank 30 to make the mixing of the drugs in the drug liquid more uniform.

[0179] When the driving member 80 drives the active drug lifting type stirring mechanism 90, and the active drug lifting type stirring mechanism 90 and the driven drug lifting type stirring mechanism 100 work synchronously through the transmission of the transmission mechanism 110, the concentrated drug solution can be further concentrated effectively, so that the drug content per unit volume of the drug solution is further increased on the basis of the original concentration, and the drug content per unit volume can also be more uniform.

[0180] The above different embodiments can be combined, replaced and used in conjunction with each other.
