Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine decoction piece processing and concentration technology, specifically referring to a traditional Chinese medicine decoction piece concentration device. Background Technology

[0002] After soaking and extracting Chinese medicinal herbs, an extract is obtained. During the export and processing of the extract, a large amount of fine medicinal powder and residue particles are carried along. When the extract is transported to the concentration device, if there is a large airflow disturbance inside the device, some of the fine medicinal powder will be dispersed with the steam and adhere to the inner wall of the device cavity, making it difficult to recover and process. At the same time, it will cause the proportion of effective components in the concentrated liquid to be unstable.

[0003] Currently, for wet medicinal residues of Chinese herbal medicines that still contain a large amount of fine medicinal powder after preliminary solid-liquid separation by centrifugation, pressure filtration or sedimentation, the usual practice is still to use stacking drying or direct high-temperature concentration. If such materials are stacked and aggregated, the hot airflow cannot fully penetrate the gaps between the materials, the heat medium cannot fully contact the materials, the medicinal powder particles cannot be heated evenly, and they are prone to agglomeration. If concentrated directly at high temperature, the surface of the material with a high content of medicinal powder particles will quickly lose water and form a hard shell, and the internal moisture and volatile effective ingredients will not be able to escape smoothly, reducing the quality of the concentrated liquid or concentrate of Chinese medicine. Therefore, there is a need for a device that can be divided into cylinders for carrying, hot air for penetration, and for classifying and concentrating the material according to the remaining weight after hot spraying. Summary of the Invention

[0004] In response to the above situation and to overcome the shortcomings of the existing technology, this solution provides a Chinese herbal medicine concentration device that can spray hot air into the extract of Chinese herbal medicine slices in separate cylinders, so that the hot air can penetrate the gaps between the materials, the powder particles in the materials are heated evenly, and the Chinese herbal medicine slices can be classified and concentrated according to the remaining weight of the Chinese herbal medicine slices after heating.

[0005] The technical solution adopted in this plan is as follows: This plan proposes a traditional Chinese medicine decoction piece concentration device, including a support frame, a liquid storage tank, a rotary hot air blowing mechanism, and an elastic weighing-type classification and concentration mechanism. The liquid storage tank is located at one end of the support frame, the rotary hot air blowing mechanism is located on the upper wall of the support frame, and the elastic weighing-type classification and concentration mechanism is located on the rotary hot air blowing mechanism. The rotary hot air blowing mechanism includes a driving component, a circular ring fixing component, a magnetic suction bearing component, and a hot spray component. The driving component is located on the side wall of the support frame, the circular ring fixing component is located on the driving component, the magnetic suction bearing component is located on the side wall of the circular ring fixing component, and the hot spray component is located on the side wall of the liquid storage tank. The elastic weighing-type classification and concentration mechanism includes a weighing component and a concentration component. The weighing component is located on the circular ring fixing component, and the concentration component is located on the inner wall of the support frame.

[0006] As a further preferred embodiment of the present invention, the drive assembly includes a drive motor, a drive shaft, and a ring frame. The drive motor is located on the top side wall of the support frame, the drive shaft is rotatably located on the inner wall of the support frame, the power end of the drive motor passes through the support frame and is connected to the drive shaft, and multiple sets of the ring frames are located on the outside of the drive shaft. The circular ring fixing assembly includes a circular ring plate, a sleeve, a sliding sleeve, and an adsorption electromagnet. The circular ring plate is disposed on the inner wall of the circular ring frame, and multiple sets of sleeves are disposed through the side wall of the circular ring plate. The sliding sleeve is slidably disposed at the end of the sleeve away from the circular ring plate, and the adsorption electromagnet is disposed on the side of the sliding sleeve away from the sleeve. The magnetic bearing assembly includes a magnetic mesh cylinder, a plug, and a filter cotton cylinder. The magnetic mesh cylinder is located on the side of the adsorption electromagnet away from the sliding sleeve. The magnetic mesh cylinder is made of magnetically conductive metal material. When the adsorption electromagnet is energized, it magnetically attracts the magnetic mesh cylinder, thereby fixing the magnetic mesh cylinder to the side wall of the sliding sleeve. The inner wall of the magnetic mesh cylinder is provided with a filter cloth layer. The plug is located at the end of the magnetic mesh cylinder away from the adsorption electromagnet and is threadedly connected to the magnetic mesh cylinder. The plug is used to seal the filling port of the magnetic mesh cylinder. The mesh of the magnetic mesh cylinder is used to allow the hot airflow to enter and the moisture evaporated from the material to escape. The filter cotton cylinder is located on the outside of the sliding sleeve and is located on the filtration path of the outward airflow after the hot air is sprayed. The thermal spray assembly includes a hot air duct, a hot air generator, an air duct, an air distribution box, and hot air nozzles. The hot air duct is located on the side wall of the liquid storage tank. The hot air generator is located inside the hot air duct. The air inlet of the hot air generator passes through the hot air duct and is connected to the demisting filter chamber at the top of the liquid storage tank. The demisting filter chamber is used to demist and filter the air entering the hot air generator and is isolated from the liquid surface in the liquid storage tank. The air duct passes through the hot air duct and is connected to the air outlet of the hot air generator. The air distribution box is connected to the end of the air duct away from the hot air generator. Multiple sets of hot air nozzles are connected to the bottom wall of the air distribution box.

[0007] In initial use, the adsorption electromagnet is non-magnetic and is separated from the magnetic mesh cylinder. Rotating the plug separates it from the magnetic mesh cylinder. The wet herbal medicine slices, still containing fine powder after initial solid-liquid separation, are then loaded into the magnetic mesh cylinder through the opening. The plug is screwed into the opening of the magnetic mesh cylinder. The adsorption electromagnet is energized and becomes magnetic, attracting the magnetic mesh cylinder. The magnetic force fixes the magnetic mesh cylinder to the side wall of the sliding sleeve. A hot air generator draws air filtered through the demisting filter chamber at the top of the storage tank. The air is heated by the hot air generator and flows into the air distribution box through the air duct. The air distribution box sprays high-temperature hot air onto the magnetic mesh cylinder through hot air nozzles. The hot air enters the magnetic mesh cylinder through the mesh and comes into contact with the herbal medicine slices, heating the material and promoting moisture evaporation. This reduces the dispersion of powder particles with steam and mitigates the adverse effects of fine powder.

[0008] Preferably, the weighing assembly includes a weighing spring and a proximity switch. The weighing spring is located between the sleeve and the sliding sleeve, and the proximity switch is located on the inner wall of the sleeve at the end away from the sliding sleeve. The concentration assembly includes a partition plate, a low-temperature concentration tank, a high-temperature concentration tank, and a heater. The partition plate is located on the inner wall of the support frame. The low-temperature concentration tank is located on the side of the partition plate near the storage tank, and the high-temperature concentration tank is located on the side of the partition plate away from the low-temperature concentration tank. Both the low-temperature concentration tank and the high-temperature concentration tank have openings at the top. The heaters are located at the bottom of the low-temperature concentration tank and the high-temperature concentration tank, respectively.

[0009] During use, the moisture in the Chinese herbal medicine slices evaporates after being sprayed with hot air, causing a change in the weight of the material. Under the condition that the loading volume and initial moisture content are basically the same, the more medicinal powder particles the material inside the magnetic mesh cylinder contains, the greater the remaining mass of the material after heating and evaporation. The magnetic mesh cylinder pulls the weighing spring under the weight of the Chinese herbal medicine slices, causing the sliding sleeve to slide away from the side wall of the annular plate along the sleeve, making the proximity switch unable to sense the sliding sleeve. At this time, the corresponding adsorption electromagnet is de-energized and demagnetized, and the heavier magnetic mesh cylinder detaches from the adsorption electromagnet. The magnetic mesh cylinder carries the Chinese herbal medicine slices with high medicinal powder particle content into the low-temperature concentration tank, where it is concentrated at a relatively low temperature. This avoids the formation of a hard shell after the rapid evaporation of moisture on the surface of the material, which would hinder the escape of moisture and volatile active ingredients from the material.

[0010] Specifically, the support frame is equipped with a controller on its side wall.

[0011] The controller is electrically connected to the drive motor, the adsorption electromagnet, the hot air generator, the proximity switch, and the heater.

[0012] The beneficial effects achieved by this solution using the above structure are as follows: Compared with the existing technology, this solution adopts a combination of a rotary hot air blowing mechanism and an elastic weighing classification and concentration mechanism. Through the setting of driving components, circular ring fixing components, magnetic bearing components, hot air blowing components, weighing components and concentration components, it can perform hot air blowing of Chinese herbal medicine extracts containing medicinal powder particles. On the one hand, it can reduce the amount of material accumulation in the extract of Chinese herbal medicine slices, and allow hot air to flow through the gaps between materials without stirring the materials, so as to heat the materials evenly. On the other hand, the extracts of Chinese herbal medicines are carried in separate cylinders, making it easier to detect changes in the weight of the material in each cylinder. This amplifies the overall weight of the material in each cylinder, allowing the temperature of the subsequent concentration process to be matched based on the remaining weight of the material after heating. After thermal spraying, the heavier magnetic mesh cylinder falls into the low-temperature concentration chamber and is concentrated at a relatively low initial temperature, allowing the moisture to evaporate slowly and achieving simultaneous internal and external concentration of the material. After thermal spraying, the lighter magnetic mesh falls into the high-temperature concentration chamber, where the concentration process is completed at a relatively high initial temperature, shortening the processing time of the entire batch of Chinese herbal medicine materials.

The magnetic mesh cylinder 14 is made of magnetically conductive metal material. After the adsorption electromagnet 12 is energized, it is magnetically attracted to the magnetic mesh cylinder 14, thereby fixing the magnetic mesh cylinder 14 to the side wall of the sliding sleeve 11. The inner wall of the magnetic mesh cylinder 14 is provided with a filter cloth layer. The plug 15 is located at the end of the magnetic mesh cylinder 14 away from the adsorption electromagnet 12.

The filter cotton cylinder 16 is located on the outside of the sliding sleeve 11 and is located on the filtration path of the outward airflow after the hot air is sprayed. The thermal spray assembly 17 includes a hot air duct 18, a hot air generator 19, an air duct 20, an air distribution box 21, and hot air nozzles 22.

The air distribution box 21 is connected to the end of the air duct 20 away from the hot air generator 19. Multiple sets of hot air nozzles 22 are connected to the bottom wall of the air distribution box 21.

[0020] The weighing assembly 24 includes a weighing spring 25 and a proximity switch 26. The weighing spring 25 is located between the sleeve 10 and the sliding sleeve 11, and the proximity switch 26 is located on the inner wall of the end of the sleeve 10 away from the sliding sleeve 11. The concentration assembly 27 includes a partition plate 28, a low-temperature concentration tank 29, a high-temperature concentration tank 30, and a heater 31. The partition plate 28 is located on the inner wall of the support frame 1. The low-temperature concentration tank 29 is located on the side of the partition plate 28 near the liquid storage tank 2. The high-temperature concentration tank 30 is located on the side of the partition plate 28 away from the low-temperature concentration tank 29. Both the low-temperature concentration tank 29 and the high-temperature concentration tank 30 have openings at the top. The heater 31 is located at the bottom of the low-temperature concentration tank 29 and the high-temperature concentration tank 30, respectively.

[0021] The support frame 1 is equipped with a controller 32 on its side wall.

[0022] The controller 32 is electrically connected to the drive motor 5, the adsorption electromagnet 12, the hot air generator 19, the proximity switch 26, and the heater 31, respectively.

[0023] In actual use, in the initial state, the adsorption electromagnet 12 is non-magnetic, the weighing spring 25 is in the initial undeformed state, the adsorption electromagnet 12 is separated from the magnetic mesh cylinder 14, the operator rotates the plug 15, the plug 15 is separated from the magnetic mesh cylinder 14, the wet material of Chinese herbal medicine slices that still contain fine medicinal powder after preliminary solid-liquid separation is loaded into the magnetic mesh cylinder 14 through the opening, and then the plug 15 is screwed into the opening of the magnetic mesh cylinder 14 to complete the loading and sealing operation of the Chinese herbal medicine slices extract material; The controller 32 controls the adsorption electromagnet 12 to be energized, and the adsorption electromagnet 12 generates magnetism. The adsorption electromagnet 12 and the magnetic mesh cylinder 14 are magnetically attracted. The adsorption electromagnet 12 fixes the magnetic mesh cylinder 14 to the side wall of the sliding sleeve 11 through the magnetic force. The controller 32 controls the hot air generator 19 to start. The hot air generator 19 draws air that has been demisted and filtered by the demisting filter chamber at the top of the liquid storage tank 2. After being heated by the hot air generator 19, the air flows into the air distribution box 21 through the air guide pipe 20. The air distribution box 21 sprays the high-temperature hot air evenly onto the magnetic mesh cylinder 14 through the hot air nozzle 22. The hot air enters the interior of the magnetic mesh cylinder 14 through the mesh and comes into contact with the extract of Chinese herbal medicine. The hot air heats the material, accelerates the evaporation of moisture inside the material, reduces the dispersion of fine medicinal powder particles with steam, and mitigates the adverse effects of the dispersion of medicinal powder particles. The controller 32 controls the drive motor 5 to start, and the drive motor 5 rotates intermittently, causing the magnetic mesh cylinder 14 to stop at the hot spray position and the weighing position, thus driving the magnetic mesh cylinder 14 to enter below the hot air nozzle 22 in sequence. The hot air generator 19 works intermittently to generate hot air flow, causing the hot air nozzle 22 to intermittently perform hot spraying operation on the Chinese herbal medicine extract material inside the magnetic mesh cylinder 14. The power end of the drive motor 5 drives the ring frame 7 and the ring plate 9 to rotate through the drive shaft 6. The ring plate 9 drives the magnetic mesh cylinder 14, which is adsorbed on the side wall of the adsorption electromagnet 12, to enter below the hot air nozzle 22 through the sleeve 10 and the sliding sleeve 11. The hot air flow generated by the hot air generator 19 is sprayed onto the magnetic mesh cylinder 14 through the hot air nozzle 22 to perform hot spraying treatment on the Chinese herbal medicine extract material inside the magnetic mesh cylinder 14. After the hot air is sprayed, the air flow carrying the medicine powder and droplets flows outward and is filtered and adsorbed by the filter cotton cylinder 16. During the pause of the drive motor 5, the centrifugal force and vibration affecting the weighing spring 25 decrease, and the deformation of the weighing spring 25 is used to reflect the remaining weight of the material in the magnetic mesh cylinder 14. After being blown by the hot air nozzle 22, the magnetic mesh cylinder 14 rotates 180° and reaches the low-temperature concentration tank 29 on the side of the partition plate 28 near the liquid storage tank 2. Under the condition that the loading volume and initial moisture content are basically the same, the higher the content of medicinal powder particles inside the extract of Chinese herbal medicine, the greater the weight of the remaining material after heating and evaporation. The magnetic mesh cylinder 14 pulls the weighing spring 25 to deform and extend under the weight of the Chinese herbal medicine material. The sliding sleeve 11 slides away from the side wall of the annular plate 9 along the sleeve 10, so that the proximity switch 26 cannot sense the sliding sleeve 11. The controller 32 controls the corresponding adsorption electromagnet 12 to be de-energized and demagnetized based on the signal that the proximity switch 26 does not sense the sliding sleeve 11. The heavier magnetic mesh cylinder 14 separates from the adsorption electromagnet 12. The magnetic mesh cylinder 14 carries the Chinese herbal medicine material with high content of medicinal powder particles into the low temperature concentration box 29 for concentration at a relatively low initial temperature, thereby avoiding the formation of a hard shell after the rapid evaporation of the surface moisture of the material, which would hinder the escape of moisture and volatile effective components from the material. For proximity switch 26, the corresponding adsorption electromagnet 12 of sliding sleeve 11 can still be sensed, maintaining magnetic adsorption on magnetic mesh cylinder 14. For adsorption electromagnet 12 that still maintains magnetic adsorption, after maintaining the duration of one hot spray cycle, the magnetic mesh cylinder 14 currently below hot air nozzle 22 will enter below hot air nozzle 22 under the drive of drive motor 5 after hot spray ends. The annular plate 9 will drive the magnetic mesh cylinder 14 to the top of high temperature concentration tank 30 through sleeve 10 and sliding sleeve 11. The adsorption electromagnet 12 will be de-energized and demagnetized, and the magnetic mesh... The cylinder 14 carries the Chinese herbal medicine materials with low powder particle content into the high-temperature concentration chamber 30, where they are concentrated at a relatively high initial temperature, shortening the processing time of the entire batch of Chinese herbal medicine materials. For the adsorption electromagnet 12, which is de-energized and demagnetized due to the proximity switch 26 not sensing the sliding sleeve 11, causing the magnetic mesh cylinder 14 to fall off, after one hot spray cycle, the controller 32 controls it to be energized again to generate magnetism. The operator then adsorbs a new set of magnetic mesh cylinders 14 onto the side wall of the adsorption electromagnet 12 to continuously perform hot spray concentration of the Chinese herbal medicine materials. The controller 32 controls the heater 31 to start, and the two sets of heaters 31 heat the interior of the low-temperature concentration tank 29 and the high-temperature concentration tank 30 respectively. The low-temperature concentration tank 29 and the high-temperature concentration tank 30 respectively concentrate the Chinese herbal medicine materials inside them. The above operation can be repeated for the next use. The above classification is based on the remaining weight of the material after thermal spraying, rather than directly calculating the weight loss rate. In the absence of an initial weighing module, by controlling the loading volume and initial moisture content to be basically the same, the remaining weight can indirectly reflect the content of the powder particles and the difficulty of subsequent concentration. The above "low temperature concentration box" and "high temperature concentration box" refer to the two being at relatively lower and higher temperatures, respectively. The specific temperature can be set according to the type of material and process requirements.

[0025] The present solution and its implementation methods have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present solution; the actual structure is not limited to this. In conclusion, if a person skilled in the art, inspired by this description, designs a similar structure and embodiment without departing from the inventive intent of this solution, such design should fall within the protection scope of this solution.
