Description

Technical Field

[0001] This application relates to the technical field of alcohol precipitation tanks, and in particular to an alcohol precipitation tank for refining and separating traditional Chinese medicine decoctions. Background Technology

[0002] Traditional Chinese medicine decoctions contain a large amount of proteins, tannins, resins, starch, mucilage, pectin, and pigments. During the extraction and purification process, it is necessary to effectively remove these components and enrich the active ingredients to improve the clarity and stability of liquid preparations, while reducing the dosage of solid preparations. Alcohol precipitation is a commonly used method for purifying traditional Chinese medicine decoctions. Its principle mainly utilizes the dissolving effect of ethanol on the active ingredients to remove some or all of the impurities from the decoction.

[0003] The equipment used in the alcohol precipitation method is an alcohol precipitation tank. After adding ethanol and the decoction of Chinese medicinal materials into the alcohol precipitation tank, the mixture is stirred to separate into layers. Then the ethanol solution is discharged. However, during the stirring process, impurities inevitably adhere to the inner wall of the alcohol precipitation tank. It is necessary to open the tank periodically to manually remove the impurities, which has a low removal efficiency. Summary of the Invention

[0004] To improve the efficiency of impurity removal, this application provides an alcohol precipitation tank for refining and separating traditional Chinese medicine decoction.

[0005] The alcohol precipitation tank for refining and separating traditional Chinese medicine decoction liquid provided in this application adopts the following technical solution: An alcohol precipitation tank for refining and separating traditional Chinese medicine decoction liquid includes: The reaction vessel has a receiving groove on its inner wall; The rotating ring is rotatably connected to the reaction vessel. The inner side is connected to a scraper that abuts against the inner wall of the reaction vessel, and the outer side is fixedly connected to a trigger rack. The liquid outlet pipe includes a fixed pipe that is fixedly installed on the reaction vessel and a swing pipe that is hinged to one end of the fixed pipe located inside the reaction vessel. The swing pipe is connected to the fixed pipe. When the swing pipe is rotated into the receiving tank, the swing pipe is completely embedded in the inner wall of the reaction vessel. The adjustment assembly includes a first transmission wheel fixedly connected to the hinged end of the swing tube, a second transmission wheel rotatably connected to the fixed tube, and a transmission belt sleeved between the first and second transmission wheels. The transmission assembly includes a trigger gear shaft rotatably connected to the reaction vessel, a first bevel gear coaxially connected to the trigger gear shaft, and a second bevel gear coaxially connected to the second transmission wheel. The first bevel gear meshes with the second bevel gear, and the tooth profile of the trigger gear shaft is adapted to the trigger rack.

[0006] By adopting the above technical solution, when a large amount of impurities accumulate on the inner wall of the reaction tank, rotating the rotating ring will allow the scraper to slide along the inner wall of the reaction tank and scrape off the impurities. One rotation of the rotating ring can quickly complete the impurity cleaning work. The liquid outlet pipe is used to discharge the upper layer of clear liquid from the reaction tank. Before the scraper contacts the swing tube when the rotating ring rotates, the trigger rack will mesh with the trigger gear shaft as the rotating ring rotates, driving the gear shaft to rotate. Through the meshing of the first bevel gear and the second bevel gear, the second transmission wheel rotates, driving the transmission belt to move. The first transmission wheel rotates accordingly, and the swing tube can be retracted into the receiving tank without affecting the scraper's passage.

[0007] Optionally, the reaction vessel includes: Tank body; The can lid is rotatably connected to both sides of the rotating ring, respectively, of the can body; A connecting component that connects the tank body and the tank lid.

[0008] By adopting the above technical solution, the separate design of the tank body and the tank cover allows the inner and outer rings of the rotating ring to be located on the inner and outer sides of the tank body, respectively. This allows the rotating ring to rotate normally without affecting the sealing effect between the tank body and the tank cover, thus reducing leakage.

[0009] Optionally, the connection component includes: Connecting arm, used to securely connect the can lid; Connecting plate, used to securely connect the tank body; The connecting bolt has its threaded end penetrating the connecting plate and threadedly connecting to the connecting arm.

[0010] By adopting the above technical solution, the can lid and the can body can be connected as a whole by the connecting arm. Tightening the connecting bolts can adjust the distance between the can lid and the can body, thereby adjusting the pressure of the can lid and the can body on the rotating ring and adjusting the sealing performance.

[0011] Optionally, a cooling jacket is fitted onto the outer wall of the tank.

[0012] By adopting the above technical solution, the temperature of the Chinese herbal decoction entering the tank is relatively high. The low temperature liquid circulated in the cooling jacket can quickly cool the tank and reduce the temperature inside the tank.

[0013] Optionally, the tank body is provided with an annular guide rail, and the tank lid is connected to a slider that is slidably connected to the guide rail.

[0014] By adopting the above technical solution, the slider slides on the guide rail, which makes the rotation between the can lid and the can body more stable.

[0015] Optionally, the inner ring wall of the rotating ring is provided with teeth, and the reaction vessel is provided with a drive motor, the output shaft of which is connected to a drive gear that meshes with the teeth.

[0016] By adopting the above technical solution, the drive motor drives the drive gear to rotate, and the drive gear can mesh to drive the rotating ring to rotate, thereby cleaning the inner wall of the reaction vessel by the scraper.

[0017] Optionally, the alcohol precipitation tank also includes a reset assembly. The reaction vessel is provided with a rotating support for rotating the trigger gear shaft. The reset assembly includes: The limit rod is fixedly connected to the rotating support; The swing lever is inserted into the circumferential side wall of the trigger gear shaft; A coil spring, with one end connected to the trigger gear shaft and the other end connected to the limit rod, is used to move the swing arm toward the limit rod.

[0018] By adopting the above technical solution, in its natural state, the coil spring pushes the trigger gear shaft, causing the swing rod to abut the limit rod. At this time, the position of the trigger gear shaft matches the position of the trigger rack. When the trigger rack rotates and contacts the trigger gear shaft, it can directly mesh with the trigger gear shaft, driving the trigger gear shaft to rotate, and the swing tube is retracted into the receiving groove. When the trigger rack disengages from the trigger gear shaft, the scraper completely passes through the swing tube, and the coil spring can drive the trigger gear shaft to reset, the swing tube reopens, and can normally draw liquid from the upper clear liquid.

[0019] Optionally, the alcohol precipitation tank also includes a stirring assembly, which includes: The stirring motor is mounted on the tank lid; The stirring shaft is rotatably connected to the tank lid and is connected to the output shaft of the stirring motor. The first stirring blade is set on the stirring shaft, with a trapezoidal longitudinal section, and multiple blades are arranged along the circumference of the stirring shaft.

[0020] By adopting the above technical solution, the stirring motor drives the stirring shaft to rotate, and the first stirring blade can stir the mixture in the reaction tank.

[0021] Optionally, the stirring assembly further includes a second stirring blade disposed at the bottom end of the stirring shaft, the second stirring blade being propeller-shaped.

[0022] By adopting the above technical solution, the second stirring blade can agitate the mixture, accelerating the absorption of the effective components in the decoction of traditional Chinese medicine by the alcohol solution.

[0023] Optionally, the oscillating tube is equipped with a filter screen.

[0024] By adopting the above technical solution, the filter screen can reduce impurities in the clean liquid drawn in by the oscillating tube.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. When a lot of impurities accumulate on the inner wall of the reaction vessel, rotate the rotating ring and the scraper can slide along the inner wall of the reaction vessel to scrape off the impurities. The impurity cleaning work can be completed quickly with one rotation of the rotating ring. 2. The liquid outlet pipe is used to discharge the upper clear liquid in the reaction tank. Before the rotating ring scraper contacts the swing tube, the trigger rack will rotate with the rotating ring and mesh with the trigger gear shaft, driving the gear shaft to rotate. Through the meshing of the first bevel gear and the second bevel gear, the second transmission wheel rotates and drives the transmission belt to move. The first transmission wheel rotates accordingly, and the swing tube can be put into the receiving tank without affecting the scraper's passage. 3. The separate design of the tank body and the tank cover allows the inner and outer sides of the rotating ring to be located on the inner and outer sides of the tank body, respectively. This allows the rotating ring to rotate normally without affecting the sealing effect between the tank body and the tank cover, thus reducing leakage. 4. The temperature of the Chinese herbal decoction entering the tank is relatively high. Passing low-temperature liquid into the cooling jacket can quickly cool the tank and reduce the temperature inside the tank. 5. In its natural state, the coil spring pushes the trigger gear shaft, causing the swing rod to abut the limit rod. At this time, the position of the trigger gear shaft matches the position of the trigger rack. When the trigger rack rotates and contacts the trigger gear shaft, it can directly mesh with the trigger gear shaft, driving the trigger gear shaft to rotate, and the swing tube is retracted into the receiving groove. When the trigger rack disengages from the trigger gear shaft, the scraper completely passes through the swing tube, and the coil spring can drive the trigger gear shaft to reset, the swing tube reopens, and can normally draw liquid from the upper clear liquid.

[0027] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail below.

[0028] This application proposes an alcohol precipitation tank for the purification and separation of traditional Chinese medicine decoction liquid, referring to... Figure 1 and Figure 2 The system includes a reaction vessel 1, a rotating ring 2, an outlet pipe 3, an adjusting assembly 4, a transmission assembly 5, a reset assembly 6, and a stirring assembly 7. The rotating ring 2 is rotatably connected to the reaction vessel 1, with a scraper 21 connected to its inner side and a trigger rack 22 connected to its outer ring wall. The outlet pipe 3 includes a fixed pipe 31 fixedly inserted into the reaction vessel 1 and a swing pipe 32 hinged to the end of the fixed pipe 31. The adjusting assembly 4 is located on the outlet pipe 3 and is used to adjust the swing angle of the swing pipe 32. The transmission assembly 5 is located on the reaction vessel 1, and the trigger rack 22 can trigger the transmission assembly 5, causing the transmission assembly 5 to drive the adjusting assembly 4 to work, thus realizing the swing of the swing pipe 32. The reset assembly 6 is located on the reaction vessel 1 and is used to reset the swing pipe 32 after the trigger rack 22 disengages from the transmission assembly 5. The stirring assembly 7 is located on the reaction vessel 1 and is used to stir the mixture inside the reaction vessel 1.

[0029] When a lot of impurities accumulate on the inner wall of the reaction vessel 1, rotating the rotating ring 2 will allow the scraper 21 to slide along the inner wall of the reaction vessel 1 and scrape off the impurities. The impurity cleaning work can be completed quickly by rotating the rotating ring 2 once.

[0030] The reaction vessel 1 is used to hold a mixture of ethanol solution and traditional Chinese medicine decoction, and includes a vessel body 11, a lid 12, and a connecting assembly 13. The vessel body 11 is an open-top cylindrical body with a conical bottom and a slag discharge pipe for discharging the settled traditional Chinese medicine residue. The vessel body 11 contains the mixture, and after sedimentation, the residue accumulates at the bottom of the vessel body 11. A valve is installed on the slag discharge pipe to control its opening and closing. A cooling jacket 111 is welded onto the vessel body 11. Since the traditional Chinese medicine decoction enters the vessel body 11 at a relatively high temperature, cold water is introduced into the cavity between the cooling jacket 111 and the vessel body 11 to cool the vessel body 11. The lid 12 is an elliptical end cap, coaxially aligned with the vessel body 11, and forms a single unit with the vessel body 11 via the connecting assembly 13. The lid 12 is equipped with a traditional Chinese medicine decoction feed pipe and an ethanol solution feed pipe for adding and replenishing materials to the vessel body 11. The tank lid 12 is also equipped with a manhole, allowing operators to enter the tank 11 for maintenance.

[0031] The connecting assembly 13 includes a connecting arm 131, a connecting plate 132, and connecting bolts 133. Multiple sets of connecting assemblies 13 are evenly distributed around the circumference of the can lid 12. The connecting arm 131 is C-shaped, with one end welded to the can lid 12 and the other end bent towards the can body 11. The connecting plate 132 is welded to the can body 11 and is vertically opposite the connecting arm 131 below it. The connecting bolt 133 has its nut facing downwards, and its threaded end passes upwards through the connecting plate 132 and is threadedly connected to the connecting arm 131. By tightening the connecting bolt 133, the distance between the can lid 12 and the can body 11 can be adjusted, thereby adjusting the pressure of the can lid 12 and the can body 11 on the rotating ring 2 and regulating the sealing performance.

[0032] Reference Figure 2 and Figure 3 The rotating ring 2 is rotatably connected between the tank body 11 and the tank cover 12. Sealing rings 26 are provided between the rotating ring 2 and both the tank body 11 and the tank cover 12 to improve the sealing between the rotating ring 2 and the reaction vessel 1. In this embodiment, the sealing rings 26 are made of polytetrafluoroethylene (PTFE). A guide rail 112 is bolted to the top of the cooling jacket 111. The guide rail 112 has an annular T-shaped cross-section. A slider 121 is bolted to the bottom of the rotating ring 2. The slider 121 is slidably connected to the guide rail 112, allowing the rotating ring 2 to rotate stably between the tank body 11 and the tank cover 12. A scraper 21 is bolted to the inner side of the rotating ring 2, adapting to and fitting the shape of the inner wall of the tank body 11, and is used to scrape away impurities adhering to the inner wall of the tank body 11. A drive motor 24 is bolted to the can lid 12. The output shaft of the drive motor 24 passes downward into the can lid 12 and is connected to a drive gear 25. The inner ring wall of the rotating ring 2 is provided with teeth 23. The drive gear 25 meshes with the rotating ring 2, and the rotating ring 2 can be rotated by the drive of the drive motor 24.

[0033] Reference Figure 2 and Figure 4The tank body 11 is provided with a receiving groove 14, the wall of which is located between the tank body 11 and the cooling jacket 111. The liquid outlet pipe 3 includes a fixed pipe 31 and a swing pipe 32. The fixed pipe 31 is a rectangular pipe, which is fixedly installed on the cooling jacket 111, with one end of it inserted into the cooling jacket 111 located in the receiving groove 14. The swing pipe 32 is also a rectangular pipe, with one end hinged to the end of the fixed pipe 31 located in the receiving groove 14 and communicating with the inside of the fixed pipe 31; the other end is a swing end, used to draw up the upper layer of clear liquid in the tank body 11. The swing end inlet of the swing pipe 32 is connected to a filter screen 321, which can reduce impurities in the clear liquid drawn into the tank body 11 by the swing pipe 32.

[0034] The adjusting assembly 4 includes a first drive wheel 41, a second drive wheel 42, and a drive belt 43. The first drive wheel 41 is rotatably connected to the fixed pipe 31, and its shaft passes through the fixed pipe 31 and is fixedly connected to the swing pipe 32. When the first drive wheel 41 rotates relative to the fixed pipe 31, the swing pipe 32 rotates relative to the fixed pipe 31. The second drive wheel 42 is rotatably connected to the side wall of the fixed pipe 31, located outside the tank 11, and has the same specifications as the first drive wheel 41. The drive belt 43 is sleeved on the first drive wheel 41 and the second drive wheel 42 and is used to transmit the torque between the first drive wheel 41 and the second drive wheel 42. A protective cover 44 is also welded onto the fixed pipe 31. The protective cover 44 covers the adjusting assembly 4 and is used to isolate the adjusting assembly 4 from the mixture inside the tank 11. The first drive wheel 41, the second drive wheel 42, and the drive belt 43 can be driven by belt drive or chain drive. In this embodiment, the first drive wheel 41 and the second drive wheel 42 are both synchronous pulleys, and the drive belt 43 is a synchronous belt.

[0035] A rotating support 113 is welded to the outer wall of the cooling jacket 111, and two rotating supports 113 are provided vertically. A trigger rack 22, which is an arc-shaped rack, is bolted to the circumferential outer wall of the rotating ring. The transmission assembly 5 includes a trigger gear shaft 51, a first bevel gear 52, and a second bevel gear 53. The trigger gear shaft 51 is rotatably connected to the two rotating supports 113, and its top end is used to mesh with the trigger rack 22. The first bevel gear 52 is coaxially connected to the bottom end of the trigger gear shaft 51. The second bevel gear 53 is coaxially connected to the second transmission wheel 42 and meshes with the first bevel gear 52. When the rotating ring 2 rotates to mesh with the trigger gear shaft 51, the continued rotation of the rotating ring 2 will cause the first bevel gear 52 at the bottom of the trigger gear shaft 51 to rotate, and the second bevel gear 53 will rotate accordingly and drive the second transmission wheel 42 to rotate. The second transmission wheel 42 will then cause the first transmission wheel 41 to rotate through the transmission belt 43, and the swing tube 32 can be put into the receiving groove 14, so that the scraper 21 can pass normally through the swing tube 32.

[0036] Reference Figure 2 and Figure 5The reset assembly 6 includes a limiting rod 61, a swing rod 62, and a coil spring 63. The reset assembly 6 can be mounted on any of the rotating supports 113. In this embodiment, the reset assembly 6 is mounted on the lower rotating support 113. The limiting rod 61 is vertically inserted into the rotating support 113, the swing rod 62 is vertically inserted into the circumferential sidewall of the trigger gear shaft 51, and the coil spring 63 has one end inserted into the limiting rod 61 and the other end inserted into the trigger gear shaft 51, sleeved on the trigger gear shaft 51. In its natural state, the coil spring 63 pushes the trigger gear shaft 51, causing the swing rod 62 to abut against the limit rod 61. At this time, the position angle of the trigger gear shaft 51 matches the angle when the trigger rack 22 rotates. When the trigger rack 22 rotates and contacts the trigger gear shaft 51, it can directly mesh with the trigger gear shaft 51, driving the trigger gear shaft 51 to rotate and causing the swing tube 32 to be drawn into the receiving groove 14. When the trigger rack 22 disengages from the trigger gear shaft 51, the scraper 21 completely passes through the swing tube 32, and the coil spring 63 can drive the trigger gear shaft 51 to reset. The swing tube 32 then rotates out of the receiving groove 14 again, and can then normally draw liquid from the upper clear liquid.

[0037] The stirring assembly 7 includes a stirring motor 71, a stirring shaft 72, a first stirring blade 73, and a second stirring blade 74. The stirring motor 71 is bolted to the tank cover 12, and the stirring shaft 72 is rotatably connected to the tank cover 12 and keyed to the output shaft of the stirring motor 71. The first stirring blade 73 is detachably connected to the middle of the stirring shaft 72, and has an isosceles trapezoidal longitudinal section. It is used to stir the mixture in the tank 11, accelerating the absorption of the effective components in the decoction of traditional Chinese medicine by the ethanol solution. The second stirring blade 74 is located at the bottom of the stirring shaft 72 and is propeller-shaped. It is used to agitate the mixture at the bottom of the tank 11, improving the stirring effect of the mixture.

[0038] The implementation principle of this application embodiment is as follows: When it is necessary to clean impurities inside the tank 11, the drive motor 24 is started, and the rotating ring 2 can rotate. The scraper 21 scrapes the impurities off the inner wall of the tank 11. When the scraper 21 approaches the swing tube 32, the trigger rack 22 meshes with the trigger gear shaft 51, and the trigger gear shaft 51 can rotate. Through the first bevel gear 52 and the second bevel gear 53, the trigger gear shaft 51 drives the second transmission wheel 42 to rotate. The second transmission wheel 42 then drives the first transmission wheel 41 to rotate through the transmission belt 43. The swing tube 32 can rotate into the receiving groove 14 to be stored, so that the scraper 21 will not interfere with the swing tube 32. When the scraper 21 passes the position of the swing tube 32, the trigger rack 22 disengages from the trigger gear shaft 51, and the trigger gear shaft 51 can be reset under the action of the coil spring 63. The swing tube 32 will also rotate out of the receiving groove 14, and normal liquid suction can be performed.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
