Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine extraction technology, specifically to a traditional Chinese medicine extraction and concentration device. Background Technology

[0002] The concentrator consists of a vertical heater, concentrator, condenser, and pipeline valves, etc. The vacuum system can be equipped with a hydraulic ejector or vacuum system with other equipment.

[0003] For example, Chinese patent CN213724875U discloses a decompression concentration device for traditional Chinese medicine extracts. Its main structure includes a concentration tank, a motor, and a vacuum pump box. The top of the concentration tank is bolted to the motor box, and the motor is bolted inside the motor box. The vacuum pump box is bolted to the outer wall of the concentration tank. A water inlet pipe is installed through one side of the outer wall of the concentration tank. A fixing box is bolted to the top of the inner side of the concentration tank, and a gas-liquid separator is bolted inside the fixing box. A door is bolted to the other side of the outer wall of the concentration tank. Water can be added to the concentration tank through the water inlet pipe. The rotating agitator cleans the inside of the concentration tank, facilitating cleaning by operators. The vacuum pump extracts gas from the inside of the concentration tank, reducing the internal pressure. This lower pressure reduces the boiling point of water evaporation, improving the efficiency of traditional Chinese medicine concentration.

[0004] In practice, because a large amount of water vapor in the inner cavity of the concentration tank cannot be discharged in time, when the water vapor particles encounter the inner wall of the concentration tank, they will adhere to its surface. Since the water vapor is not discharged in time, a large amount of water vapor will accumulate on the inner wall of the concentration tank. Under the continuous accumulation, the attached liquid particles will continue to grow larger and eventually fall back to the liquid under the action of gravity, resulting in the need for another ineffective evaporation process, which seriously reduces the evaporation efficiency.

[0005] To solve the above-mentioned technical problems, a common approach is to install a condenser at the steam discharge point of the tank. High-temperature steam flows along the pipe into the condenser and accumulates in liquid form inside, thereby reducing the occurrence of ineffective evaporation caused by water vapor accumulation.

[0006] However, since liquid drugs are processed under vacuum or negative pressure, the gas in the inner cavity of the concentration tank is extracted to form a vacuum, which leads to a significant reduction in the gas content inside the concentration tank. Since there is almost no gas inside, the flow of high-temperature water vapor relies mainly on its own high-temperature effect, resulting in a slow flow rate and low concentration efficiency. Summary of the Invention

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this invention provides a traditional Chinese medicine extraction and concentration device that uses negative pressure to heat the medicine, featuring a low boiling point and high evaporation efficiency. Furthermore, since the negative pressure is controlled by adjusting the difference between the exhaust speed of the negative pressure pump and the inlet speed of the outside air, the negative pressure itself possesses airflow, allowing trace amounts of gas to enter the evaporation chamber. This gas flows upwards within the evaporation chamber, guiding the evaporated medicinal liquid particles towards the next stage. This timely clearing of high-temperature water vapor within the evaporation chamber effectively reduces the volume and density of the water vapor, facilitating the subsequent generation of high-temperature water vapor and thus improving concentration efficiency, thereby solving the aforementioned technical problems.

[0011] Preferably, it also includes a conical drainage groove, which is disposed at the bottom of the evaporation chamber. One side of the conical drainage groove is inclined downward and is connected to the inlet port of the liquid discharge pipe on the inclined side.

[0012] Preferably, the thickness of the top end face of each part of the annular closed heating cavity and the thickness of the bottom port of the evaporation cavity at each corresponding part are the same.

[0013] Preferably, the vacuum pump is a gas rotary pump.

[0014] Preferably, the exhaust-type rotating structure includes a sleeve. The bottom end of the sleeve is provided with an upwardly recessed component mounting groove that can be rotatably installed at the top of the pipe body through a mechanical seal structure. The top of the component mounting groove is provided with an upwardly recessed gas pre-reservation cavity. The circumferential surface of the sleeve is provided with multiple transverse branch rods arranged in a ring array. The center of each transverse branch rod is provided with a gas flow cavity that connects to the gas pre-reservation cavity and is closed at one end. The multiple transverse branch rods are provided with multiple oblique holes in the same rotation direction for discharging the gas inside the gas pre-reservation cavity.

[0015] Preferably, the angle between the centerline A of the oblique hole and the horizontal line X is greater than zero degrees and less than forty-five degrees.

[0016] Preferably, the diameter L1 of the oblique hole at the end of the gas flow cavity is larger than the diameter L2 of the port located on the outside.

[0017] Preferably, it also includes a vortex-type airflow heating structure, which is inserted into the concentration tank and has an vortex coil and a copper rod inside that can heat the gas flowing into the gas inlet pipe.

[0018] Preferably, the vortex-type airflow heating structure includes a cylindrical shell made of insulating and heat-insulating material. The cylindrical shell has a component mounting hole with a bottom opening at its center.

An electromagnetic valve for controlling the gas flow is installed in the gas flow hole. An eddy current coil is placed around the component mounting hole on the cylindrical shell. The first and second terminals of the eddy current coil extend to the corresponding sides of the cylindrical shell. A copper rod is placed at the center of the component mounting hole. There is a certain gap between the copper rod and the wall of the component mounting hole to allow gas flow. The copper rod extending from the bottom port of the component mounting hole is fixed to the bottom of the cylindrical shell by a support rod made of insulating and heat-insulating material.

[0019] Preferably, after the eddy current is applied to the eddy current coil, the high temperature generated by the copper rod is required to heat the temperature of the gas flowing around it to a temperature not less than that of the high-temperature liquid vapor inside the evaporation chamber.

[0020] Compared with the prior art, the present invention provides a traditional Chinese medicine extraction and concentration device, which has the following beneficial effects:

[0021] This traditional Chinese medicine extraction and concentration device uses negative pressure to heat the medicine, featuring a low boiling point and high evaporation efficiency. Furthermore, since the negative pressure is controlled by adjusting the difference between the exhaust speed of the negative pressure pump and the inlet speed of the outside air, the negative pressure itself has airflow, allowing a small amount of gas to enter the evaporation chamber. This gas flows from bottom to top inside the evaporation chamber, thus guiding the evaporated medicinal liquid particles and discharging them to the next stage. This timely clearing of the high-temperature water vapor inside the evaporation chamber effectively reduces the space occupied by the high-temperature water vapor and lowers its density, which is beneficial for the subsequent generation of high-temperature water vapor, thereby improving the concentration efficiency.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1 and Figure 2 A traditional Chinese medicine extraction and concentration device includes a concentration tank 1 with legs 5 installed at the bottom, an evaporation chamber 2 disposed inside the concentration tank 1, and a liquid discharge pipe 4 disposed on one side of the concentration tank 1 for discharging liquid from the evaporation chamber 2. To ensure complete discharge of the concentrated liquid, a conical drainage groove 3 is preferably disposed at the bottom of the evaporation chamber 2, with one side of the conical drainage groove 3 inclined downwards and connected to the inlet of the liquid discharge pipe 4 on this downwardly inclined side. A liquid injection pipe 9 is disposed diagonally above the concentration tank 1 for injecting traditional Chinese medicine liquid into the evaporation chamber 2. The evaporation chamber 2 is equipped with a closed observation port 10, a thermometer 11 for observing the internal temperature, and a pressure gauge 12 for observing the internal pressure. Operators can pour unconcentrated Chinese medicine liquid into the evaporation chamber 2 through the liquid injection pipe 9 and then close the liquid injection pipe 9. During the concentration process, the negative pressure intensity and temperature inside the evaporation chamber 2 can be observed with the naked eye, thereby controlling the corresponding functions to control the internal environment to achieve the required environmental intensity. After the work is completed, the concentrated liquid can be discharged by opening the valve set in the liquid discharge pipe 4.

[0031] For high-temperature steam heating of the medicinal solution, please refer to [link / reference]. Figure 2 A ring-shaped closed heating chamber 6 needs to be set up, located directly below the evaporation chamber 2. To ensure uniform heating of the liquid medicine at the bottom of the evaporation chamber 2, the thickness between the top end face of each part of the ring-shaped closed heating chamber 6 and the bottom port of the corresponding part of the evaporation chamber 2 needs to be consistent. The high-temperature steam inlet 7 and high-temperature steam outlet 8 set on the corresponding sides of the ring-shaped closed heating chamber 6 can be connected to the corresponding steam flow port of an external steam heater. By connecting to the external steam heater, after the steam heater is working, the temperature of its circulating high-temperature steam can be set, so that the high-temperature steam can circulate through the high-temperature steam inlet 7 and high-temperature steam outlet 8. When the high-temperature steam circulates to the ring-shaped closed heating chamber 6, it will heat the bottom of the liquid medicine, thereby achieving the necessary conditions for the liquid medicine to absorb heat, so that the liquid medicine can boil and generate water vapor, thereby achieving concentration.

[0032] To achieve negative pressure treatment of evaporator chamber 2, please refer to... Figure 1 and Figure 2 A vacuum pump 14 is required. In order to reduce the negative impact on high-temperature water vapor during the gas extraction process, the vacuum pump 14 needs to be a gas rotary pump body. The rotary design of the pump body allows water vapor to be discharged in a flowing form, and will not form water droplets due to the accumulation of steam caused by piston compression. It is set at the top of the concentration tank 1, and the air inlet is connected to the top of the evaporation chamber 2. The exhaust port can be connected to the inlet of the external condenser through a pipe. After the vacuum pump 14 is started, the gas inside the evaporation chamber 2 can be extracted, so that the gas pressure inside the evaporation chamber 2 is lower than the external atmospheric pressure, thus forming a low-pressure zone. The drug is heated in a negative pressure form, which has the characteristics of low boiling point and high evaporation efficiency.

[0033] To allow a small amount of external gas to enter the evaporation chamber 2, please refer to [link / reference needed]. Figure 2 It is necessary to set up an external gas inlet pipe body 13, which is integrated and longitudinally set in the center of the evaporation chamber 2, with the bottom port extending into the bottom structure of the concentration tank 1 and the top open. After the vacuum pump 14 is started, by controlling the exhaust volume of the vacuum pump 14 and the maximum intake volume of the external gas inlet pipe body 13, a pressure difference is formed between the exhaust volume and the intake volume. This pressure difference is the negative pressure intensity. The trace amount of gas entering the evaporation chamber 2 can enter the interior of the evaporation chamber. The gas flows from bottom to top inside the evaporation chamber, thereby guiding the evaporated drug particles.

[0034] To ensure that the introduced trace gas generates driving force and increases its influence on the high-temperature steam, please refer to [link / reference needed]. Figure 2 A rotary exhaust structure 15 needs to be installed, which is rotatably mounted at the top port of the external gas inlet pipe 13 via a mechanical seal structure. Inside this structure is an inclined hole 156 that generates a rotatable reaction force during exhaust. Due to the suction of the vacuum pump 14, external gas enters the transverse branch rod 154 through the external gas inlet pipe 13, and then exits into the evaporation chamber 2 through the inclined hole 156. By controlling the exhaust angle of the inclined hole 156, the high-speed flowing gas can generate a reaction force on the transverse branch rod 154. The horizontal branch rod 154 is driven to make a circular motion. Due to this circular motion, the trace gas discharged through the inclined hole 156 can form a spiral trajectory in the evaporation chamber 2, thereby increasing the contact area between the trace gas and the high-pressure water vapor in the evaporation chamber 2. This, in turn, guides the flow of more high-temperature water vapor and discharges it into the next mechanism, thus timely clearing the high-temperature water vapor located inside the evaporation chamber. This effectively reduces the space volume occupied by the high-temperature water vapor inside the evaporation chamber, reduces its density, and is conducive to the subsequent generation of high-temperature water vapor, thereby improving the concentration efficiency.

[0035] For details regarding the exhaust-type rotating structure 15, please refer to [link / reference]. Figure 3 and Figure 4 The system includes a sleeve 151. The bottom end of the sleeve 151 has an upwardly recessed component mounting groove 152 that allows external gas to enter the top of the pipe body 13 and can be rotatably installed via a mechanical seal structure. The top of the component mounting groove 152 has an upwardly recessed gas pre-reservation cavity 153. The circumferential surface of the sleeve 151 has multiple horizontally arranged branch rods 154 in a ring array. The center of each horizontal branch rod 154 has a gas flow cavity 155 that connects to the gas pre-reservation cavity 153 and is closed at one end. Multiple horizontal branch rods 154 have multiple oblique holes 156 in the same rotational direction for discharging gas from the gas pre-reservation cavity 153. To ensure that the gas discharged through the oblique holes 156 generates both a horizontal reaction force and is discharged obliquely upwards, please refer to [reference needed]. Figure 5 The angle between the centerline A of the inclined hole 156 and the horizontal line X needs to be greater than zero degrees and less than forty-five degrees. Force analysis shows that this angle design allows the reaction force generated by the gas discharged through the inclined hole 156 to be divided into a horizontal reaction force and a longitudinal reaction force. The horizontal reaction force is greater than the longitudinal reaction force, thus causing more reaction force to act on the transverse branch rod 154, pushing it to rotate. Since the gas in the inclined hole 156 is discharged obliquely upwards, the external gas moves in a spiral upward motion inside the evaporation chamber 2, driving the internal high-temperature water vapor to move upwards, providing necessary guidance and ensuring timely discharge of the water vapor. To ensure that the gas flowing through the inclined hole 156 is in a high-speed flow state, please refer to... Figure 5 This allows the diameter L1 of the oblique hole 156 at the end of the gas flow chamber 155 to be larger than the diameter L2 of the port located outside. Gas can enter through the diameter L1 and be discharged outward through the diameter L2. Due to the size relationship, the gas passing through the oblique hole 156 will exhibit a compressed flow form, thereby further increasing the gas flow speed.

[0036] To achieve heating of the incoming gas and thus reduce the negative impact of external gas on the high-temperature water vapor inside evaporation chamber 2, please refer to [link / reference needed]. Figure 1 and Figure 2A vortex-type airflow heating structure 16 needs to be set up. It is inserted into the concentration tank 1 and has a vortex coil 166 and a copper rod 164 inside to heat the gas flowing into the gas inlet pipe 13. Using the principle of vortex heating, the high-speed gas flowing around the copper rod 164 can be heated quickly. The heated gas enters the evaporation chamber 2. By controlling the temperature of the heated gas, it can be ensured that there is no large temperature difference between it and the high-temperature water vapor after it enters, so as to ensure that the high-temperature water vapor will not form low-temperature condensation into droplets in the evaporation chamber 2, thereby reducing the negative impact on the high-temperature water vapor.

[0037] For details regarding the specific structure of the vortex airflow heating structure 16, please refer to [link / reference needed]. Figure 6 The device includes a cylindrical outer shell 161 made of insulating and heat-insulating material. A component mounting hole 162 with a bottom opening is located at the center of the cylindrical outer shell 161. A gas flow hole 169, connecting to the bottom air inlet port of the gas inlet pipe 13, is located at the top of the component mounting hole 162. An electromagnetic valve 165, capable of controlling the gas flow, is installed in the gas flow hole 169. An eddy current coil 166 is placed around the component mounting hole 162 on the cylindrical outer shell 161. The first terminal 167 and the second terminal 168 of the eddy current coil 166 extend to the corresponding sides of the cylindrical outer shell 161. A copper rod 164 is located at the center of the component mounting hole 162. To prevent the heated gas from negatively affecting the high-temperature water vapor, the high temperature generated by the copper rod 164 after the eddy current coil 166 is applied must be such that... The temperature of the copper rod 164 is heated to a temperature not less than that of the high-temperature medicinal vapor inside the evaporation chamber 2 by the surrounding gas. There is a certain gap between the copper rod 164 and the wall of the component mounting hole 162 to allow gas flow. The copper rod 164, extending from the bottom port of the component mounting hole 162, is fixed to the bottom of the columnar outer shell 161 by a support rod 163 made of insulating and heat-insulating material. In use, the first terminal 167 and the second terminal 168 are connected to a controller that can generate alternating current and control the output alternating current. By controlling the alternating current entering the eddy current coil 166 through the controller, the temperature of the copper rod 164 when it generates high temperature can be controlled. When the gas flows along the gap between the copper rod 164 and the eddy current coil 166, it will generate a high temperature state due to heat exchange, thereby achieving the effect of high-temperature heating of the flowing gas.

[0038] In use, firstly, connect the exhaust port of the vacuum pump 14 to the inlet port of the condenser through a pipe. Then, connect the high-temperature steam inlet 7 and the high-temperature steam outlet 8 to the corresponding steam flow port of a steam heater. Finally, connect the first terminal 167 and the second terminal 168 to a controller that can generate alternating current and control the output alternating current. Then, the operator pours the unconcentrated Chinese medicine liquid into the evaporation chamber 2 through the medicine injection pipe 9, then closes the medicine injection pipe 9, adjusts the temperature generated by the copper rod 164, and starts the vacuum pump 14 and the steam heater to concentrate the liquid. During the concentration process, the negative pressure intensity and temperature inside the evaporation chamber 2 can be observed visually, thereby controlling the corresponding functions to control the internal environment to achieve the required environmental intensity. After the work is completed, the concentrated medicine liquid can be discharged by opening the valve set in the medicine discharge pipe 4.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
