Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically to a medicinal liquid concentration device for traditional Chinese medicine processing. Background Technology

[0002] In the field of traditional Chinese medicine (TCM) processing, liquid concentration equipment is one of the core pieces of equipment for modernizing TCM production. It is widely used in the processing of prepared TCM herbs and the production of prepared TCM formulations (such as ointments, oral liquids, and capsules). In the processing of prepared TCM herbs, concentration transforms the extracted liquid into an extract, facilitating subsequent drying and shaping. In the production of prepared TCM formulations, the concentration process directly affects the content, stability, and clinical efficacy of the active ingredients, making it a crucial step in ensuring drug quality. With the large-scale development of the TCM industry, higher demands are placed on the efficiency, energy consumption, and automation level of concentration equipment, especially in preserving medicinal components and minimizing the loss of active ingredients. In the prior art, a traditional Chinese medicine liquid concentration device (CN202420680177.X) is disclosed, which mainly consists of a casing, a motor, an air pump, an electric heating tube, and a condensing jacket. The motor at the top of the casing drives the connecting pipe to rotate via gear transmission. The horizontal aeration pipe connected to the lower end of the connecting pipe rotates with the motor, causing the aeration heads to move in a circular motion, thus expanding the aeration area. The gas delivered by the air pump is heated inside the casing and then enters the connecting pipe through the gas delivery pipe and the rotary joint, reducing the influence of ambient temperature gas on the temperature of the medicinal liquid. The condensing jacket is connected to the steam outlet and, together with the heat dissipation fins, achieves steam condensation and recovery, reducing solvent loss. Furthermore, the aeration heads at both ends of the aeration pipe are inclined to aerate the medicinal liquid on the inner wall of the casing. The fixed rod reinforces the rotary joint to ensure stability, and the insulation cotton outside the gas delivery pipe reduces gas temperature loss. This device has achieved certain results in improving concentration efficiency by optimizing the aeration method and temperature control. However, the aforementioned device still has significant limitations in actual operation. During the concentration process, as the solvent evaporates, the viscosity of the herbal liquid gradually increases, making it prone to adhering to the inner wall of the machine casing. On the one hand, the adhering liquid cannot be completely discharged during the discharge process; on the other hand, the adhered liquid forms an insulating layer, hindering heat transfer from the electric heating element, prolonging the concentration cycle, and affecting production efficiency. Particularly noteworthy is the contact area between the liquid surface and the inner wall of the machine casing. Due to the rapid solvent evaporation and long residence time of the liquid, the solvent evaporates even faster at this point, making it easier for the herbal solutes to precipitate and adhere to the wall, forming a ring of deposits. As the liquid level continues to drop, the new ring-shaped area where the liquid surface contacts the container wall repeats this process, continuously forming new layers of deposits. Ultimately, the liquid surface at different stages leaves behind rings of stratification, and the existing structure lacks an effective cleaning mechanism for this boundary area. Utility Model Content

[0003] To address the technical deficiencies in the background art, this utility model proposes a medicinal liquid concentration device for traditional Chinese medicine processing. To further solve the aforementioned technical problems and meet practical needs, the specific technical solution is as follows: A medicinal liquid concentration device for processing traditional Chinese medicine includes an evaporation kettle and a scraping assembly installed inside the evaporation kettle. The scraping assembly includes a rotating shaft disposed inside the evaporation kettle, a motor disposed at the top of the evaporation kettle and connected to the rotating shaft, a first mounting rod and a second mounting rod alternately arranged around the rotating shaft and connected to the lower end of the rotating shaft, a fixed scraper corresponding to the first mounting rod and with its working surface in close contact with the evaporation kettle, and a floating scraper corresponding to the second mounting rod and with its working surface in close contact with the evaporation kettle. A plurality of first telescopic members are installed between the fixed scraper and the first mounting rod. A floating sleeve capable of floating and limiting vertical movement is sleeved outside the second mounting rod. A plurality of second telescopic members are installed between the floating scraper and the floating sleeve.

[0004] As a further technical solution of this utility model, the telescopic end of the first telescopic member is connected to the fixed scraper, the fixed end of the first telescopic member is connected to the first mounting rod, the telescopic end of the second telescopic member is connected to the floating scraper, and the fixed end of the second telescopic member is connected to the floating sleeve.

[0005] As a further technical solution of this utility model, the surface of the second mounting rod is provided with a plurality of floating slots, the slots of which extend along the length direction of the second mounting rod and are distributed in a rotationally symmetrical manner on the surface of the second mounting rod. The inner wall of the floating sleeve is provided with floating strips that correspond to the floating slots and can slide inside the floating slots. The floating sleeve is provided with a cavity inside.

[0006] As a further technical solution of this utility model, the first telescopic member and the second telescopic member have the same structure, both including an outer tube, a chassis sliding groove disposed inside the outer tube and extending along the length of the outer tube, a push rod with one end disposed in the chassis sliding groove, a spring disposed in the chassis sliding groove and located on one side of the push rod, and a sliding chassis connected to the end of the push rod placed in the chassis sliding groove.

[0007] As a further technical solution of this utility model, the sliding chassis is slidably disposed in the chassis sliding groove, and the spring is disposed in the chassis sliding groove with its two ends respectively connected to the sliding chassis and the inner wall of the bottom of the chassis sliding groove.

[0008] As a further technical solution of this utility model, the upper and lower sides of the chassis sliding groove are symmetrically provided with sliding grooves that are connected to and parallel to the chassis sliding groove, and the inside of the sliding groove is provided with a guide rod that is parallel to the push rod and whose two ends are connected to the inner sidewall of the sliding groove.

[0009] As a further technical solution of this utility model, the upper and lower sides of the sliding chassis are respectively connected to a sliding plate that can slide on the guide rod. The surface of the sliding plate is provided with a sliding hole, and the guide rod is sleeved in the sliding hole provided in the sliding plate.

[0010] The beneficial effects of this utility model are as follows: This invention effectively solves the problem of drug residue adhering to the vessel wall during drug concentration by incorporating a scraping assembly. The fixed scraper, thanks to the first telescopic component, remains in close contact with the inner wall of the evaporator. During rotation, it continuously scrapes away the adhering drug residue, preventing the formation of an insulating layer, ensuring efficient heat transfer, and shortening the concentration cycle. The floating scraper, via a floating sleeve, floats up and down along the second mounting rod, automatically adjusting its position as the liquid level drops. It specifically cleans the annular area where the liquid surface meets the inner wall, preventing the formation of stratified deposits and addressing the insufficient cleaning of this area in existing devices. The spring structure of the first and second telescopic components adaptively adjusts the scraper pressure, ensuring thorough scraping while avoiding damage to the vessel wall. The cooperation of the floating slot and the locking strip ensures stable lifting and lowering of the floating scraper, improving cleaning accuracy. The overall design reduces drug residue, increases the yield, retains more active ingredients, and reduces manual cleaning costs. Attached Figure Description

Detailed Implementation

[0017] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0018] like Figures 1 to 5 As shown, this utility model provides a technical solution: a medicinal liquid concentration device for processing traditional Chinese medicine, including an evaporating kettle 1 and a scraping assembly 2 installed inside the evaporating kettle 1. The scraping assembly 2 includes a rotating shaft 22 disposed inside the evaporating kettle 1, a motor 21 disposed on the top of the evaporating kettle 1 and connected to the rotating shaft 22, a first mounting rod 23 and a second mounting rod 24 alternately arranged around the rotating shaft 22 and connected to the lower end of the rotating shaft 22, a fixed scraper 25 corresponding to the first mounting rod 23 and with its working surface in close contact with the evaporating kettle 1, and a floating scraper 26 corresponding to the second mounting rod 24 and with its working surface in close contact with the evaporating kettle 1. A plurality of first telescopic members 28A are installed between the fixed scraper 25 and the first mounting rod 23. A floating sleeve 27 capable of floating and limiting vertical movement is sleeved outside the second mounting rod 24. A plurality of second telescopic members 28B are installed between the floating scraper 26 and the floating sleeve 27.

[0019] Furthermore, in the above structure, the telescopic end of the first telescopic member 28A is connected to the fixed scraper 25, the fixed end of the first telescopic member 28A is connected to the first mounting rod 23, the telescopic end of the second telescopic member 28B is connected to the floating scraper 26, and the fixed end of the second telescopic member 28B is connected to the floating sleeve 27.

[0020] This invention uses a motor 21 to drive a rotating shaft 22 to rotate, which in turn drives the first mounting rod 23 and the second mounting rod 24 to rotate synchronously. A heating sleeve 11 is provided on the outer wall of the evaporator 1 to heat the evaporator 1. The first mounting rod 23 is connected to a fixed scraper 25 through a first telescopic member 28A. The spring 285 in the outer tube 281 pushes the sliding base 283, causing the slide plate 284 to slide along the guide rod 286, which drives the push rod 282 to keep the fixed scraper 25 in close contact with the inner wall of the evaporator 1. During rotation, the scraper continuously scrapes off the liquid adhering to the wall, avoiding the formation of a heat insulation layer, ensuring heat transfer efficiency to shorten the concentration cycle, reduce the loss of effective ingredients, and at the same time reduce the residue of the liquid and increase the output rate.

[0021] The floating groove 241 of the second mounting rod 24 engages with the floating strip 272 of the floating sleeve 27, allowing the floating sleeve 27 to float vertically and with limited range. The floating scraper 26, connected via the second telescopic component 28B, adheres tightly to the inner wall with the aid of a spring 285. As the liquid level drops, the floating scraper 26 adjusts its position according to the liquid level, specifically cleaning the area where the liquid surface meets the inner wall to prevent the formation of layered deposits. The rotationally symmetrical groove and strip design ensures stable lifting and lowering, improving cleaning accuracy. The springs 285 of the first telescopic component 28A and the second telescopic component 28B can adaptively adjust the pressure, compressing when encountering protrusions to avoid damaging the vessel wall, and resetting in smooth areas to ensure thorough scraping. The coordinated operation of all components effectively solves the problem of wall adhesion, improves heat transfer efficiency and automation, reduces labor costs, and adapts to the needs of large-scale production.

[0022] As one of the preferred embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the surface of the second mounting rod 24 is provided with a plurality of floating slots 241. The slots of the floating slots 241 extend along the length of the second mounting rod 24. The floating slots 241 are distributed in a rotationally symmetrical manner on the surface of the second mounting rod 24. The inner wall of the floating sleeve 27 is provided with floating strips 272 that correspond to the floating slots 241 and can slide inside the floating slots 241. The floating sleeve 27 is provided with a cavity 271 inside.

[0023] The floating groove 241 on the surface of the second mounting rod 24 extends along its length, providing a guide track for the lifting and lowering of the floating sleeve 27. This ensures that the floating sleeve 27 can slide stably along the axial direction of the second mounting rod 24, meeting the position adjustment requirements when the liquid level drops. The floating groove 241 is rotationally symmetrically distributed and precisely cooperates with the floating strip 272 on the inner wall of the floating sleeve 27. This restricts the circumferential rotation of the floating sleeve 27 relative to the second mounting rod 24, ensuring that the floating scraper 26 rotates synchronously with the rotation axis 22. This prevents misalignment of the scraping direction due to sleeve offset, ensuring accurate cleaning of the interface area.

[0024] The cavity 271 inside the floating sleeve 27 provides space for the second mounting rod 24 to pass through, while reducing the contact area between the two and lowering the frictional resistance during sliding, allowing the floating sleeve 27 to adjust its height more flexibly according to changes in the liquid level. The second mounting rod 24 and the floating sleeve 27 are limited by the engagement of the floating groove 241 and the floating strip 272, balancing the flexibility of floating and the stability of rotation, providing reliable structural support for the floating scraper 26 to specifically clean the interface area of ​​the liquid surface.

[0025] As one of the preferred embodiments of this utility model, such as Figure 3 and Figure 4As shown, the first telescopic member 28A and the second telescopic member 28B have the same structure, both including an outer tube 281, a chassis sliding groove 287 disposed inside the outer tube 281 and extending along the length of the outer tube 281, a push rod 282 with one end disposed in the chassis sliding groove 287, a spring 285 disposed in the chassis sliding groove 287 and located on one side of the push rod 282, and a sliding chassis 283 connected to one end of the push rod 282 placed in the chassis sliding groove 287.

[0026] The homogeneous structure of the first telescopic component 28A and the second telescopic component 28B ensures the stress stability of the fixed scraper 25 and the floating scraper 26. The outer tube 281 serves as the basic load-bearing structure, and its internal chassis sliding groove 287 extends along its length, providing a directional track for the telescopic movement of the push rod 282 and preventing deviation. One end of the push rod 282 is embedded in the chassis sliding groove 287, and the other end is connected to the scraper, becoming the force transmission carrier.

[0027] Spring 285 is located within the sliding groove 287 of the base plate and close to push rod 282. Its elastic force is transmitted through the sliding base 283 connected to push rod 282, ensuring that push rod 282 always has an outward pushing force, thus ensuring that the scraper is in close contact with the inner wall of the evaporator 1. The sliding base 283 increases the contact area between push rod 282 and the tank body, improving the stability of the extension and retraction process and preventing push rod 282 from tilting due to uneven force. This ensures effective scraping of the wall surface by the scraper, while the deformation buffer of spring 285 prevents damage caused by rigid collision between the scraper and the tank wall.

[0028] In one of the preferred embodiments of the present invention, the sliding base 283 is slidably disposed in the sliding groove 287 of the base, and the spring 285 is disposed in the sliding groove 287 of the base and its two ends are respectively connected to the inner wall of the bottom of the sliding base 283 and the sliding groove 287 of the base.

[0029] The sliding design of the sliding base 283 within the sliding groove 287 provides axial sliding space for the extension and retraction of the push rod 282, ensuring that the scraper can flexibly adjust its position according to the curvature of the vessel wall. The spring 285 connects to the sliding base 283 and the bottom of the sliding groove 287 at both ends, forming an elastic pre-tightening structure. When the scraper encounters a protrusion, the sliding base compresses the spring 285 and retracts; when there is no obstruction, the spring 285 resets and pushes the sliding base to make the scraper adhere tightly to the vessel wall. This combination ensures scraping force while preventing rigid contact between the scraper and the vessel wall through spring buffering, achieving adaptive fitting and protection.

[0030] As one of the preferred embodiments of this utility model, the upper and lower sides of the chassis sliding groove 287 are symmetrically provided with sliding grooves 288 that are connected to and parallel to the chassis sliding groove 287. Inside the sliding groove 288, there are guide rods 286 that are parallel to the push rod 282 and whose two ends are connected to the inner sidewall of the sliding groove 288.

[0031] The upper and lower sliding grooves 288 on both sides of the chassis sliding groove 287 are connected to and parallel to the groove body, forming a symmetrical guide structure. The guide rod 286 inside the sliding groove 288 is parallel to the push rod 282, and its two ends are fixed to the inner sidewall of the sliding groove 288, providing rigid support for the sliding component. The above structure can limit the movement trajectory of the sliding chassis 283, prevent it from radially deviating during sliding, ensure that the push rod 282 extends and retracts smoothly along the axial direction, avoid uneven wall contact caused by scraper shaking, and improve the stability and accuracy of the telescopic component's operation.

[0032] As one of the preferred embodiments of this utility model, the upper and lower sides of the sliding chassis 283 are respectively connected to a sliding plate 284 that can slide on the guide rod 286. The surface of the sliding plate 284 is provided with a sliding hole, and the guide rod 286 is sleeved in the sliding hole provided in the sliding plate 284.

[0033] The sliding plates 284 on the upper and lower sides of the sliding base 283 are fitted onto the guide rod 286 through surface sliding holes, forming a double guiding structure. When the sliding plates 284 move synchronously with the sliding base 283, the guide rod 286 passes through the sliding holes to restrict their radial displacement, preventing the sliding base 283 from swaying or rotating during extension and retraction. This cooperation enhances the linearity of the push rod 282's movement, ensuring that the scraper always remains stably and tightly against the inner wall of the evaporator 1.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
