Description

Technical Field

[0001] This invention relates to the field of vacuum concentration equipment, specifically a vacuum concentration device for the production of traditional Chinese medicine. Background Technology

[0002] In traditional Chinese medicine (TCM) production, vacuum concentration is a key process for heating and concentrating TCM extracts under sub-atmospheric pressure. Utilizing the physical property that lower pressure leads to lower boiling points, a vacuum pump reduces the pressure within the concentration equipment, allowing the solvent in the herbal solution to boil and evaporate at temperatures far below 100°C, thus achieving concentration and preventing the decomposition of heat-sensitive active ingredients. Under reduced pressure, the temperature difference between the heating source and the boiling point of the herbal solution increases significantly, greatly improving heat transfer efficiency and accelerating solvent evaporation. Compared to atmospheric pressure concentration, vacuum concentration significantly shortens production time and improves production efficiency.

[0003] The vacuum concentration equipment adopts a closed structure, which can effectively retain volatile active ingredients during decoction. However, when the mixture of Chinese medicinal materials and water boils in the container, the flaky and fine medicinal materials in the solid-liquid mixture easily adhere to and block the exhaust valve port, affecting normal exhaust and pressure relief. Existing vacuum concentration devices install baffles at the end of the exhaust valve. Due to its greater inertia, the solid-liquid mixture in the gas cannot turn quickly like gas, so it will collide with the surface of the baffle and be captured, and then flow down the wall of the baffle to separate. Because the baffle is inclined, the flaky and fine medicinal materials in the solid-liquid mixture will get stuck between the baffle and the inner wall of the exhaust valve. As the number of flaky and fine medicinal materials increases, blockage will still occur. Summary of the Invention

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to Figures 1-8 The diagram shows a vacuum concentration device for traditional Chinese medicine production, comprising a housing 1 and a processing tank 2 installed inside the housing 1. A sealing cover 3 is installed on the top of the processing tank 2, and a discharge pipe extending to the outside of the housing 1 is fixedly installed on the outside of the processing tank 2. An exhaust valve 4 is installed on the top of the sealing cover 3. An adjusting pressure rod 5, which connects to the sealing cover 3, is installed on the top of the housing 1. A heater 6, located below the processing tank 2, is installed inside the housing 1. The adjusting pressure rod 5 is removed from the top of the sealing cover 3, the sealing cover 3 is opened, and medicinal materials and water are injected into the processing tank 2. The sealing cover 3 is then placed back on the processing tank 2, and the adjusting pressure rod 5 is used to press and fix the sealing cover 3. The heater 6 is then turned on to decoct the medicinal materials and water in the processing tank 2. Steam is discharged from the processing tank 2 through the exhaust valve 4, reducing the pressure inside the processing tank 2, lowering the boiling point of the medicinal liquid, and achieving vacuum concentration. After processing, the discharge pipe is opened to discharge the concentrated medicinal liquid. The baffle mechanism includes an air inlet box 7 located below the exhaust valve 4. Two staggered and symmetrically distributed baffles 8 are arranged inside the air inlet box 7. These baffles 8 can block medicinal material fragments in the steam. The baffle mechanism also includes a mounting rod 11 fixedly installed at one end of the baffle 8. Rotating rods 12 are fixedly installed at both ends of the mounting rod 11. The rotating rods 12 are rotatably installed inside the air inlet box 7, and both ends of the mounting rod 11 and the sides of the baffle 8 are in contact with the inside of the air inlet box 7. A partition 36 is fixedly installed inside the air inlet box 7 above the baffle 8. An exhaust pipe 13 is fixedly installed at the bottom of the exhaust valve 4. The exhaust pipe 13 is fitted to the top of the air inlet box 7 via a flange. A circular hole is provided at the top of the partition 36 for the exhaust pipe 13 to pass through, allowing steam to enter the air inlet box 7. Steam enters the exhaust pipe 13 through two baffles 8, allowing it to be discharged outwards through the exhaust valve 4, thus reducing pressure on the treatment tank 2. The baffle 36 guides the airflow, facilitating steam entry into the exhaust pipe 13. A fixing plate 14 is located on the side of the mounting rod 11 away from the baffles 8. The fixing plate 14 is fixedly installed inside the air inlet box 7. One side of the fixing plate 14 has an arc-shaped structure and contacts the outer side of the mounting rod 11. A sliding plate 15 is fixedly installed on the outer side of the mounting rod 11. The arc surface of the fixing plate 14 has a sliding cavity for limiting the sliding of the sliding plate 15. Multiple first arc-shaped rods 16, equidistantly sliding through the sliding plate 15, are fixedly installed inside the sliding cavity. Multiple first springs 17, equidistantly distributed, are fixedly installed between the sliding plate 15 and the inner side of the sliding cavity. Opening the exhaust... When the exhaust valve 4 is closed, steam enters the intake box 7 and passes through the bottom baffle 8 to the bottom of the next baffle 8. Due to the large inertia of the medicinal material fragments in the gas, they will remain at the bottom of the baffle 8. The steam pushes the baffle 8 upward with the rotating rod 12 as the fulcrum, causing the mounting rod 11 to drive the sliding plate 15 to move along the sliding cavity of the fixed plate 14 and compress the first spring 17. After the exhaust valve 4 is closed, the rebound force of the first spring 17 will drive the sliding plate 15 to return to its original position, causing the sliding plate 15 to drive the baffle 8 downward through the mounting rod 11. This facilitates the downward discharge of accumulated medicinal material fragments and avoids the accumulation of medicinal material fragments. A condenser 30 is installed on the outside of the device housing 1, and the condenser 30 is connected to the exhaust valve 4 through a hose. The exhaust valve 4 discharges steam into the condenser 30 through a hose for cooling, improving the safety of steam discharge. The sealing cover 3 is hinged to the outer shell 1 with a hinge seat 31. When the adjusting rod 5 is removed from the sealing cover 3, the sealing cover 3 can be flipped up with the hinge seat 31 as the fulcrum, facilitating quick feeding and unloading. A first support cylinder 32 is fixedly installed between the partition plate 36 and the top of the inner wall of the air inlet box 7. The first support cylinder 32 is sleeved on the outside of the exhaust pipe 13, providing auxiliary support for the exhaust pipe 13 and ensuring the stability of steam discharge. A rubber gasket 33 is fixedly installed inside the round hole of the partition plate 36 and sleeved on the outside of the exhaust pipe 13, improving the sealing between the exhaust pipe 13 and the partition plate 36 and preventing air leakage.

[0022] Example 2: Please refer to Figure 2 -- Figure 6 This embodiment further illustrates Example 1. The discharge mechanism shown in the figure includes a baffle 9 disposed below the baffle 8. The baffle 9 can shake out the debris below the baffle 8. The discharge mechanism also includes multiple baffle wheels 18 that are equidistantly rotatably mounted on the outside of the baffle 9, and the outer sides of the baffle wheels 18 are in contact with the bottom of the baffle 8. Arc-shaped plates 19 are fixedly mounted on both sides of the baffle 9. An arc-shaped block 20 is fixedly mounted on the side of the arc-shaped plate 19 away from the baffle 9. The center of the arc-shaped block 20 is the same as the center of the rotating rod 12. An arc-shaped box 21 is disposed on the outside of the arc-shaped plate 19. The arc-shaped box 21 is fixedly mounted on the outside of the air inlet box 7, and the arc-shaped plate 19 is slidably mounted on the outside of the arc-shaped box 21. The arc-shaped block 20 is slidably mounted on the inside of the arc-shaped box 21. The baffle 8 swings downward to reset. At this time, the bottom of the baffle 8 can contact the baffle wheel 18, so that the baffle wheel 18 drives the arc plate 19 to move along the outer side of the arc box 21 through the baffle rod 9. The arc plate 19 drives the arc block 20 to move along the inner side of the arc box 21. The inner side of the arc box 21 is fixedly installed with a second spring 22 that abuts against the arc block 20. The elasticity of the second spring 22 provides a buffer for the movement of the arc block 20, so that the baffle wheel 18 vibrates against the baffle 8, which facilitates the shaking out of the residual slag at the bottom of the baffle 8 and improves the slag discharge efficiency. The inner side of the arc box 21 is fixedly installed with a second arc rod 23 for the arc block 20 to slide in a limited position, which provides guidance and support for the movement of the arc block 20. The bottom of the baffle 8 is fixedly installed with a counterweight 34, which facilitates the baffle 8 to swing downward and contact the baffle wheel 18.

[0023] Example 3: Please refer to Figures 3-8This embodiment further illustrates other embodiments. The filter media mechanism shown in the figure includes a baffle 10 disposed inside the air inlet box 7. The baffle 10 can block fine fibers in the steam. The filter media mechanism also includes a filter screen 24 fixedly installed inside the baffle 10. The baffle 10 has a hollow hemispherical structure. The top of the baffle 10 has multiple centrally symmetrically distributed exhaust grooves, so that the baffle 10 provides support for the filter screen 24 and filters the fine fibers in the steam. A scraper ring 25 is provided inside the baffle 10. A driven rod 26 is fixedly installed inside the baffle 10. The driven rod 26 passes through the exhaust pipe 13 and the air inlet box 7. First transmission wheels 27 are fixedly installed at both ends of the driven rod 26. A second transmission wheel 28 is fixedly installed at the end of the two rotating rods 12 near the top of the air inlet box 7 away from the mounting rod 11. A second transmission wheel 28 is fixedly installed at one end of the mounting rod 11, and the size of the first transmission wheel 27 is smaller than that of the second transmission wheel 28. When the baffle 8 drives the rotating rod 12 to rotate through the mounting rod 11, the rotating rod 12 can drive the synchronous belt 29 to rotate through the second transmission wheel 28. The synchronous belt 29 drives the first transmission wheel 27 to rotate, so that the first transmission wheel 27 drives the scraper ring 25 to rotate along the inner side of the filter screen 24 through the driven rod 26, which facilitates the scraping of the fine fibers accumulated on the surface of the filter screen 24, which then fall onto the baffle 8 and are discharged downwards. The inner side of the air inlet box 7 is provided with a cavity for the synchronous belt 29 to be installed. Two symmetrically distributed second support cylinders 35 are fixedly installed on the inner side of the air inlet box 7. The second support cylinders 35 are sleeved on the outer side of the driven rod 26, so that the second support cylinders 35 provide auxiliary support for the driven rod 26 and ensure the smooth rotation of the driven rod 26.

[0024] Working principle: First, the operator removes the adjusting rod 5 from the top of the sealing cover 3, flips the sealing cover 3 upwards using the hinge seat 31 as a fulcrum, and then injects the medicinal materials and water into the processing tank 2. The sealing cover 3 is then closed, and the adjusting rod 5 is installed. Next, the operator turns on the heater 6 to decoct the medicinal materials and water in the processing tank 2 into a medicinal liquid. Then, the operator opens the exhaust valve 4, and the steam generated from the decoction enters the air inlet box 7. The steam then enters the exhaust pipe 13 along the inclined surfaces of the two baffles 8. During this process, due to the large inertia of the medicinal material fragments in the gas, they cannot change direction with the airflow and will remain at the bottom of the baffles 8. Furthermore, the thrust of the steam will push the baffles 8 upwards. The movement causes the baffle 8 to rotate, driving the mounting rod 11 and the rotating rod 12. The mounting rod 11 drives the sliding plate 15 to move along the sliding cavity of the fixed plate 14, causing the sliding plate 15 to compress the first spring 17. The steam entering the exhaust pipe 13 passes through the filter screen 24 inside the baffle 10, allowing the filter screen 24 to filter out the fine fibers in the steam. The treated steam then passes through the exhaust valve 4 and the hose into the condenser 30, where the condenser 30 cools the steam, achieving safe discharge of the steam. This reduces the gas pressure in the treatment tank 2, lowers the boiling point of the liquid medicine, and improves the concentration efficiency of the liquid medicine. After the exhaust valve 4 is closed, the rebound force of the first spring 17 drives the sliding plate 15 to return to its original position, allowing the sliding plate 15 to pass through the safe discharge pipe 13. The mounting rod 11 causes the baffle 8 to swing downwards, bringing its bottom into contact with the retaining wheel 18. The retaining wheel 18, via the retaining rod 9, causes the arc-shaped plate 19 to move along the outer side of the arc-shaped box 21. The arc-shaped plate 19 then causes the arc-shaped block 20 to move along the inner side of the arc-shaped box 21, compressing the second spring 22. The elasticity of the second spring 22 provides a buffer for the movement of the arc-shaped block 20, causing the retaining wheel 18 to vibrate against the baffle 8, shaking out any remaining debris at the bottom of the baffle 8. Simultaneously, during the resetting process of the baffle 8, the mounting rod 11 rotates, causing the mounting rod 11 to rotate. The rotating rod 12, via the second transmission wheel 28, drives the synchronous belt 29 to rotate, causing the synchronous belt 29 to drive the first transmission wheel 27. Rotating, the first drive wheel 27 drives the scraper ring 25 to rotate along the inner side of the filter screen 24 via the driven rod 26, scraping away the fine fibers accumulated on the surface of the filter screen 24, causing the fine fibers to fall onto the baffle 8 and be discharged from the bottom of the air inlet box 7 along the baffle 8. Finally, the medicine liquid in the processing tank 2 is processed. The operator opens the discharge pipe to discharge the concentrated medicine liquid, thus completing the depressurization and concentration processing of the medicine liquid. Finally, the operator closes the heater 6 and opens the exhaust valve 4 to make the air pressure in the processing tank 2 the same as the outside air pressure. The operator can then open the discharge valve to discharge the concentrated medicine liquid, completing the depressurization and concentration processing of traditional Chinese medicine, thereby achieving the effect of clearing blockages and preventing blockages, and ensuring the normal depressurization of the processing tank 2.
