Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine concentration, and in particular to a traditional Chinese medicine extraction and concentration device and a concentration method thereof. Background Art

[0002] Traditional Chinese medicine concentration is the process of reducing the solvent through evaporation and concentration of traditional Chinese medicine extracts, reducing the volume of the medicine and increasing its concentration. The concentrated medicine is convenient for subsequent processing, such as making pills, tablets, capsules, etc. The current common method of concentrating traditional Chinese medicine is to place the medicine in a liquid storage tank, and then pass steam into it for heating, and stir it with a frame stirring rod during the heating process to make the medicine uniformly heated until the medicine is concentrated to a certain concentration.

[0003] At present, the main problems in the process of traditional Chinese medicine concentration are as follows: 1. The method of heating by only introducing steam into the liquid storage tank has obvious limitations. First, the heat distribution of steam heating is uneven, which can easily lead to local overheating or insufficient heating of the liquid medicine, affecting the concentration effect; second, the heat energy transfer efficiency of steam heating alone is low, the solvent in the liquid medicine evaporates slowly, the concentration time is long, and the energy consumption is high.

[0004] 2. Although a certain degree of mixing can be achieved by using a frame-type stirring rod for stirring, its stirring range and strength are limited, and it is difficult to fully disperse the precipitate in the liquid medicine, which can easily cause precipitation or stratification, resulting in uneven distribution of liquid medicine components and loss of effective ingredients.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, a Chinese medicine extraction and concentration device includes a tank body 10; the lower end of the tank body 10 is a conical structure, a support tube 11 is fixedly installed on the lower surface of the tank body 10, the lower end of the tank body 10 is connected with a drain pipe 12, the other end of the drain pipe 12 is fixedly passed through the side wall of the support tube 11, a cover plate 13 is installed on the upper end of the tank body 10, an infusion tube 14 is installed on the cover plate 13, and a stirring mechanism 2 and a steam heating mechanism 3 are arranged inside the tank body 10.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the stirring mechanism 2 includes a rotating shaft 20, and the rotating shaft 20 is rotatably installed in the middle of the cover plate 13. The rotating shaft 20 is a cavity structure. The upper end of the rotating shaft 20 passes through the upper end of the cover plate 13. The upper end of the cover plate 13 is fixedly installed with a stepping motor 21 whose output shaft is fixedly connected to the rotating shaft 20 through a motor seat. A circular plate 22 is fixedly installed in the inner cavity of the tank body 10, and a support is installed on the lower end surface of the rotating shaft 20. The lower end of the support is in contact with the upper end surface of the circular plate 22. An opening and closing portion 26 is provided on the circular plate 22. A fixed plate 23 is evenly fixedly installed on the outer wall of the rotating shaft 20 along its circumference, and a stirring plate 24 located above the opening and closing portion 26 is evenly fixedly installed on the side of the fixed plate 23 away from the rotating shaft 20 from top to bottom; the rotating shaft 20 is provided with a heating portion 27 for heating the medicinal liquid from the middle of the medicinal liquid, and a peristaltic suction portion 25 for circulatively sucking the bottom medicinal liquid to the top of the liquid surface to discharge it so that the sediment is evenly distributed.

[0038] During specific operation, the external infusion mechanism is connected to the infusion tube 14, and a certain amount of liquid medicine is delivered to the tank body 10. After the delivery is completed, the steam heating mechanism 3 and the heating part 27 heat the liquid medicine in the tank body 10, so that the solvent in the liquid medicine evaporates, leaving a high concentration of effective ingredients. At the same time, the stirring mechanism 2 drives the rotating shaft 20 to rotate through the stepping motor 21, and the rotating shaft 20 stirs the liquid medicine in the tank body 10 through the stirring plate 24, so that the liquid medicine is heated evenly, and the peristaltic suction part 25 sucks the liquid medicine at the bottom to the top of the liquid surface and then discharges it. In this way, the precipitation in the liquid medicine is evenly dispersed, which helps to make the heat and material transfer more uniform and make the solvent evaporate more efficiently; at the same time, it can ensure the uniform distribution of the effective ingredients in the liquid medicine, and avoid the loss of components due to precipitation or stratification. The method of using the liquid medicine to be circulated, sucked and discharged while performing multiple heating greatly improves the efficiency of Chinese medicine concentration.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the steam heating mechanism 3 includes an annular shell 30, and the lower end of the cover plate 13 is fixedly installed with a co-centric annular shell 30, and the lower end of the annular shell 30 is evenly provided with air outlet holes, and the upper end of the cover plate 13 is fixedly installed with an air supply pipe 31 connected to the annular shell 30 and an exhaust pipe 32 connected to the tank body 10.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the heating part 27 includes a heating tube 270, an annular groove is opened between the inner wall and the outer wall of the rotating shaft 20, and the heating tubes 270 are evenly installed in the annular groove along its circumference, and the stirring plate 24 is a hollow structure, and the stirring plate 24 is connected to the annular groove; it should be noted that a conductive slip ring with a fixed outer ring, a rotating inner ring and coaxial with the rotating shaft 20 is provided at the upper end of the cover plate 13, the outer ring of the conductive slip ring is arranged on the cover plate 13, and the inner ring of the conductive slip ring is installed with a wire, which passes through the rotating shaft 20 to the annular groove and is connected to the heating tube 270, so as to avoid the wire entanglement during the rotation of the rotating shaft 20.

[0041] During specific operation, the external steam generator is connected to the air supply pipe 31, and the air supply pipe 31 is provided with an air intake check valve (not shown in the figure). The air supply pipe 31 discharges steam from the air outlet of the annular shell 30 evenly into the tank body 10, thereby improving the contact between the steam and the medicinal liquid. When the steam contacts the colder Chinese medicine extract, it will condense into water and release a large amount of latent heat. This part of heat is directly used to heat the Chinese medicine. The exhaust pipe 32 is provided with an air outlet check valve (not shown in the figure). After the pressure in the tank body 10 reaches a certain value (the internal pressure can be accurately controlled by setting a pressure sensor), the external suction pump extracts the steam and evaporated water vapor in the tank body 10 through the exhaust pipe 32 to ensure that the pressure in the tank body 10 is within a safe range. The extracted steam and water vapor can be recycled for heating the medicinal liquid in the tank body 10 after being processed by the corresponding filtering and drying equipment. At the same time, the heating pipe 270 is powered on to heat and release heat, and the medicinal liquid is stirred through the rotating shaft 20 and the stirring plate 24 to make the medicinal liquid evenly heated, thereby improving the efficiency of Chinese medicine concentration.

[0042] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the peristaltic suction part 25 includes a limiting cylinder 250, and the inner cavity of the rotating shaft 20 is evenly fixedly installed with the limiting cylinder 250 along its axial direction, and a baffle 251 is coaxially installed in the limiting cylinder 250, and a suction hose 253 with a U-shaped structure is placed between the outer wall of the baffle 251 and the side wall of the limiting cylinder 250. The suction hose 253 adopts a hose material with high elasticity, high temperature resistance and fatigue resistance, such as high elasticity silicone, to reduce deformation or wear caused by rotational friction; both ends of the suction hose 253 pass through the limiting cylinder 250, and a pressure wheel 252 that presses against the suction hose 253 is rotatably installed on the baffle 251, and a coaxial shaft 254 is fixedly installed between all the baffles 251. The lower end of the shaft 254 rotates to pass through the rotating shaft 20 and then fixedly passes through the circular plate 22. The limiting cylinder 250 is provided with a guide 4 for guiding the flow of the medicine.

[0043] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the guide member 4 includes a liquid inlet pipe 40, the liquid inlet end of the suction hose 253 is fixedly installed with the liquid inlet pipe 40, the liquid outlet end of the suction hose 253 is fixedly installed with a liquid outlet pipe 41, a liquid storage tank 43 fixedly installed on the rotating shaft 20 is arranged between two adjacent limiting cylinders 250, the other end of the liquid outlet pipe 41 penetrates from bottom to top into the adjacent liquid storage tank 43 above, a U-shaped tube 45 is arranged at the lower end of the liquid storage tank 43, both ends of the U-shaped tube 45 are connected with the inside of the liquid storage tank 43, the other end of the liquid inlet pipe 40 penetrates from top to bottom into the adjacent liquid storage tank 43 below and is connected with one end of the corresponding U-shaped tube 45, and the upper end of the rotating shaft 20 A liquid outlet hole connected to the uppermost liquid inlet pipe 40 is provided; the lower end of the lowermost liquid inlet pipe 40 is connected to a Z-shaped tube 44, and the other vertical section of the Z-shaped tube 44 is coaxial with the rotating shaft 20 and fixedly passes through the rotating shaft 20. Since the vertical section where the liquid inlet end of the Z-shaped tube 44 is located is coaxial with the rotating shaft 20, the linear speed of the Z-shaped tube 44 approaches zero, and therefore the centrifugal force is almost zero, thereby effectively avoiding the interference of the centrifugal force and ensuring that the liquid medicine is smoothly inhaled. The shaft 254 rotates and passes through the vertical section where the liquid inlet end of the Z-shaped tube 44 is located. A circular tube 42 connected to the liquid outlet hole is fixedly installed on the rotating shaft 20, and circular holes are evenly provided on the lower surface of the circular tube 42 along its axial direction.

[0044] During specific operation, the rotation of the rotating shaft 20 will drive the limiting cylinder 250 and the suction hose 253 to rotate slowly in the forward direction, while the baffle 251 remains stationary under the limiting restriction of the shaft 254. As the limiting cylinder 250 and the suction hose 253 rotate, the pressure wheel 252 will cyclically squeeze the suction hose 253; thereby, through the peristaltic pump principle: the pressure wheel 252 squeezes the suction hose 253 to close it, and pushes the fluid in the suction hose 253 toward the liquid outlet end. After the squeezing point is removed, the suction hose 253 relies on elasticity to restore its original state, generating negative pressure, thereby sucking in new fluid. In the process of periodic squeezing and releasing, the suction hose 253 is continuously compressed and restored, forming continuous suction and delivery, that is, continuous fluid delivery. The liquid inlet pipe 40 and the Z-shaped tube 44 at the bottom suck the medicine liquid at the bottom of the tank body 10 into the suction hose 253, and then suck it into the liquid outlet pipe 41, and discharge it into the corresponding liquid storage tank 43 through the liquid outlet pipe 41, while the corresponding upper suction hose 253 sucks the medicine liquid in the corresponding liquid storage tank 43 into the next liquid storage tank 43 through the liquid inlet pipe 40 and the U-shaped tube 45. In this way, the medicine liquid is pumped from bottom to top into the uppermost liquid storage tank 43, and the uppermost suction hose 253 pumps the liquid in the corresponding liquid storage tank 43 into the circular tube 42, and discharges it from the several circular holes on the circular tube 42, so that the previous sediment is evenly dispersed, achieving the material mixing effect in the upper and lower directions, and at the same time increasing the contact area between the medicine liquid and the steam, thereby improving the efficiency of Chinese medicine concentration.

[0045] It should be noted that Figure 4 , Figure 6 , Figure 7 Although it is shown that each baffle plate 251 corresponds to two pressure wheels 252, the number of pressure wheels 252 corresponding to each baffle plate 251 is not limited to two, but the number of pressure wheels 252 is at least two. By increasing the number of pressure wheels 252 and reducing the extrusion interval, a more continuous negative pressure can be maintained and the stability of the suction force can be improved.

[0046] After the concentration is completed, the opening and closing part 26 is started to connect the upper and lower sides of the inner cavity of the tank body 10, and then the stepper motor 21 drives the rotating shaft 20 to rotate in the opposite direction, and the rotating shaft 20 stirs the liquid medicine through the stirring plate 24, so that the liquid medicine is discharged with the sediment evenly distributed.

[0047] like Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the opening and closing portion 26 includes a drainage component, and a plurality of groups of drainage components are evenly arranged on the circular plate 22 along its circumference, and each group of drainage components is composed of a plurality of drainage holes evenly distributed along the radial direction of the circular plate 22. A shaft column 260 is fixedly installed on the lower end of the shaft rod 254, and a ring 261 is movably installed on the shaft column 260 through a guide member 6. A support plate 262 corresponding to the drainage component is fixedly installed on the outer wall of the ring 261 along its circumference, and a sealing head 263 corresponding to the drainage hole is fixedly installed on the upper end of the support plate 262, and a push-pull member 5 for driving the ring 261 to move up and down is provided on the tank body 10.

[0048] like Figure 2 , Figure 3 and Figure 8 As shown, the push-pull member 5 includes a cylinder 50, and the cylinder 50 is slidably sleeved on the shaft column 260. The upper end of the cylinder 50 is rotatably connected to the ring 261, and the lower end of the cylinder 50 is fixedly installed with a Z-shaped shaft 51. The other vertical section of the Z-shaped shaft 51 slides through the lower end of the tank body 10, and a telescopic cylinder 52 is fixedly installed on the lower surface of the tank body 10 through a bracket, and the telescopic section is fixedly connected to the corresponding vertical section of the Z-shaped shaft 51.

[0049] like Figure 3 , Figure 4 and Figure 8 As shown, the guide member 6 includes a guide groove 60. The outer wall of the shaft column 260 is provided with the guide groove 60. The guide groove 60 is composed of a vertical section and an arc section surrounding the circumferential surface of the shaft column 260 connected to the lower end of the vertical section. The inner wall of the ring 261 is fixedly installed with a guide column 61 that slides with the guide groove 60.

[0050] During specific operation, the telescopic cylinder 52 pulls the ring 261 downward through the Z-axis 51 and the cylinder 50. At this time, the guide column 61 slides in the vertical section of the guide groove 60 until the ring 261 drives the sealing head 263 to completely detach from the corresponding drainage hole through the support plate 262. At this time, the guide column 61 is located at the connection between the vertical section and the arc section of the guide groove 60. Then, as the ring 261 continues to move downward, the guide column 61 will slide in the arc section of the guide groove 60, so that the ring 261 rotates under the cooperation of the guide column 61 and the arc section of the guide groove 60, and the ring 261 drives the sealing head 263 away from the corresponding drainage hole through the support plate 262 to ensure the smoothness of the discharge of the concentrated liquid. The discharged concentrated liquid is discharged through the drainage pipe 12 for subsequent operations.

[0051] After the discharge is completed, the telescopic cylinder 52 pushes the ring 261 upward through the Z-axis 51 and the cylinder 50, and the ring 261 is driven to rotate with the cooperation of the guide column 61 and the arc section of the guide groove 60. The ring 261 drives the plugging head 263 to be located directly below the corresponding drainage hole through the support plate 262. At this time, the guide column 61 is located at the connection between the arc section and the vertical section of the guide groove 60. As the ring 261 continues to move upward, with the cooperation of the guide column 61 and the vertical section of the guide groove 60, the ring 261 keeps moving vertically upward and drives the plugging head 263 to block the drainage hole. At this time, the next batch of liquid medicine can be concentrated.

[0052] like Figures 1 to 8 As shown, in addition, the present invention also provides a method for extracting and concentrating traditional Chinese medicine, which is completed by using the above-mentioned traditional Chinese medicine extraction and concentration device, and includes the following steps: S1, injecting the medicinal solution into the tank body 10 through the infusion tube 14.

[0053] S2, the stirring mechanism 2 stirs the medicinal liquid in the tank body 10 through the stirring plate 24, and at the same time, the steam heating mechanism 3 and the heating part 27 heat the medicinal liquid in multiple directions to improve the efficiency of Chinese medicine concentration.

[0054] S3, the peristaltic suction part 25 circulates and sucks out the medicinal liquid from bottom to top to ensure the uniformity of the dispersion of the precipitate in the medicinal liquid and increase the contact surface between the medicinal liquid and the steam, thereby further improving the efficiency of the Chinese medicine concentration.

[0055] S4. After the concentration is completed, the opening and closing part 26 is started to connect the upper and lower sides of the inner cavity of the tank body 10, and at the same time, the stirring mechanism 2 stirs the concentrated liquid, so that the concentrated liquid is discharged while being stirred.

[0056] In the description of the present invention, it is necessary to understand that the orientation or positional relationship indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, vertical, horizontal" and "top, bottom" are usually based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. In addition, in the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
