Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine pharmaceutical equipment technology, and more specifically, to a water bath sterilizer for storing traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine preparations, especially liquid preparations such as oral liquids and injections, must undergo strict sterilization treatment during the storage stage after production and before packaging to ensure product stability and medication safety within their shelf life. Currently, moist heat sterilization is one of the most widely used sterilization methods, with the sterilization cabinet being the core equipment.

[0003] Traditional steam sterilizers use saturated steam condensation and heat release for sterilization, which has inherent drawbacks: uneven distribution of the steam medium leads to "cold spots" and "hot spots" in the temperature field inside the cabinet; its condensation heat transfer method easily creates instantaneous localized high temperatures at the walls of the medicine bottles, while the temperature rise in the center of the medicine is delayed, resulting in strong thermal stress impact; in addition, the small heat capacity of the gaseous medium and the lag in the response of the control system make it difficult to accurately control the actual heating temperature of the medicine. This problem is particularly prominent for traditional Chinese medicine preparations containing heat-sensitive components such as glycosides, volatile oils, and polysaccharides, often leading to a decrease in the content of effective ingredients, changes in product color, and even precipitation after sterilization, seriously affecting the quality and efficacy of traditional Chinese medicine products. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a water bath sterilizer for storing traditional Chinese medicine, so as to solve the technical problem of uneven internal temperature distribution in current steam sterilizers, which affects the sterilization quality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A water bath sterilization cabinet for storing traditional Chinese medicine includes a sterilization cabinet, a hot water tank fixedly installed at the bottom of the inner cavity of the sterilization cabinet, a water pumping mechanism connected to the hot water tank fixedly installed on the outer side of the hot water tank, a spray box connected to the water pumping mechanism fixedly installed at the top of the inner cavity of the sterilization cabinet, and a self-rotating flipping frame installed in the middle of the inner cavity of the sterilization cabinet. The flipping frame includes a support plate rotatably connected to the inner cavity of the sterilizer. A tray is fixedly connected between the two support plates. The top of the tray has several grooves for limiting the position of the medicine bottle. A clamping assembly for holding the medicine bottle is also fixedly installed between the two support plates. A drive motor fixedly connected to the support plate on the same side is fixedly installed on the side of the sterilizer away from the water pumping mechanism.

[0006] In this invention, the hot water tank is connected to the top spray box via a pumping mechanism, and together with the heating rod inside the hot water tank, forms a closed-loop water circulation system of "bottom heating - pumping and conveying - top spraying - reflux and recycling". Hot water can be evenly sprayed from the top of the sterilizer onto the Chinese medicine liquid bottles, and then flow back to the hot water tank through a drain plate and a bend, achieving all-round enveloping heating of the liquid bottles. This avoids the problem of incomplete sterilization caused by insufficient local temperature in traditional sterilization methods, greatly improving the sterilization qualification rate and ensuring the microbial safety of Chinese medicine during storage from the source.

[0007] Preferably, the clamping assembly includes a first clamping plate fixedly connected to the two side support plates, and a second clamping plate that cooperates with the first clamping plate is movably installed between the two side support plates. The sides of the first clamping plate and the second clamping plate that are in contact with each other are provided with clamping grooves that cooperate with each other, and the inner edge of the clamping groove is petal-shaped.

[0008] Preferably, slots are provided at both ends of the side of the first clamping plate, and inserts that are inserted into the slots are fixedly provided at both ends of the side of the second clamping plate. A limiting bolt that is threaded on the top of the first clamping plate and engages with the insert is installed.

[0009] Preferably, the opposing surfaces of the two support plates are provided with sliding grooves, and the opposing sides of the second clamping plate are fixedly provided with T-shaped sliding plates that slide with the second clamping plate.

[0010] Preferably, each of the grooves has several hemispherical support protrusions fixedly provided on its top side, and a through hole is provided at the center of the groove.

[0011] Preferably, a heating rod is fixedly installed inside the hot water tank, a drain plate is fixedly installed on the top of the hot water tank, and curved pipes passing through the side wall of the sterilizer are installed on both sides of the drain plate, with one side of the curved pipe being fixedly connected to the pumping mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the hot water tank is connected to the top spray box via a water pumping mechanism, and together with the heating rod inside the hot water tank, forms a closed-loop water circulation system of "bottom heating - water pumping and conveying - top spraying - reflux recycling". Hot water can be evenly sprayed from the top of the sterilizer onto the Chinese medicine liquid bottles, and then flow back to the hot water tank through the drain plate and the bend pipe, achieving all-round enveloping heating of the liquid bottles. This avoids the problem of incomplete sterilization caused by insufficient local temperature in traditional sterilization methods, greatly improves the sterilization qualification rate, and ensures the microbial safety of Chinese medicine during storage from the source.

[0013] 2. This utility model also utilizes a rotating frame in the center of the sterilizer cavity, driven by a motor, to rotate. Combined with the grooves on the tray for positioning the medicine bottles, this allows the medicine bottles to rotate 360° during sterilization. This ensures even contact between all surfaces of the bottle and the hot water, eliminating temperature dead zones. Furthermore, it promotes slight flow of the medicinal liquid inside the bottle, preventing uneven heating that could affect efficacy, thus further improving sterilization effectiveness and the quality of the medicine.

[0014] 3. This utility model also uses the tray groove of the flipping frame to precisely limit the position of the bottom of the medicine bottle. The hemispherical support protrusion at the top of the groove can reduce the contact area between the bottom of the bottle and the tray, which can not only prevent the bottom of the bottle from sticking and being damaged due to prolonged heating, but also allow hot water to come into full contact with the bottom of the bottle. At the same time, the first clamping plate and the second clamping plate of the clamping component cooperate, and the petal-shaped clamping groove can fit the body of medicine bottles of different sizes. Through the insertion of the insert and the slot and the fixing of the limiting bolt, the bottle body is stably clamped, preventing the medicine bottle from shaking or colliding and breaking when the flipping frame rotates.

[0017] like Figures 1 to 5As shown, this utility model relates to a water bath sterilization cabinet for storing traditional Chinese medicine, including a sterilization cabinet 1. A hot water tank 2 is fixedly installed at the bottom of the inner cavity of the sterilization cabinet 1. A water pumping mechanism 3 connected to the hot water tank 2 is fixedly installed on the outer side of the hot water tank 2. A spray box 4 connected to the water pumping mechanism 3 is fixedly installed at the top of the inner cavity of the sterilization cabinet 1. A self-rotating flipping frame 5 is installed in the middle of the inner cavity of the sterilization cabinet 1. The water pumping mechanism 3 includes a water pump and connecting pipes at both ends. The bottom of the spray box 4 is provided with a connected spray head, which are all existing technical structures and will not be described in detail here. The hot water in the hot water tank 2 is sent into the spray box 4 by the water pumping mechanism 3 for spraying, which can improve the sterilization range of the medicine bottle and improve the sterilization comprehensiveness. The design of the flipping frame 5 can limit the sterilization position of the medicine bottle.

[0018] The flipping rack 5 includes a support plate 501 rotatably connected to the inner cavity of the sterilizer 1. A tray 502 is fixedly connected between the two support plates 501. The top of the tray 502 has several grooves 503 for limiting the position of the medicine bottles. A clamping component 6 for clamping the body of the medicine bottles is also fixedly installed between the two support plates 501. A drive motor 7 fixedly connected to the support plate 501 on the same side is fixedly installed on the side of the sterilizer 1 away from the water pumping mechanism 3. The grooves 503 on the tray 502 can limit the placement of the medicine bottles, achieving a uniform sterilization position. The design of the clamping component 6 can clamp and limit the medicine bottles, making them less likely to fall off when the flipping rack 5 is rotated by the drive motor 7. At the same time, the flipping operation can mix the medicine inside the medicine bottle with the medicine on the surface, improving the sterilization effect.

[0019] In an embodiment of this utility model, the clamping assembly 6 includes a first clamping plate 601 fixedly connected to the two side support plates 501, and a second clamping plate 602 that cooperates with the first clamping plate 601 is movably installed between the two side support plates 501. The sides of the first clamping plate 601 and the second clamping plate 602 that are in contact with each other are provided with mutually cooperating clamping grooves 603, and the inner edge of the clamping groove 603 is petal-shaped. The clamping position of the medicine bottle can be easily adjusted by the movably installed second clamping plate 602. The material of the clamping groove 603 is a flexible and elastic material, which increases the effect of clamping and protecting the medicine bottle. The petal shape can reduce the contact surface and facilitate the flow of hot water spray.

[0020] In the embodiments of this utility model, slots 604 are provided at both ends of the side of the first clamping plate 601, and inserts 605 that are inserted into the slots 604 are fixedly provided at both ends of the side of the second clamping plate 602. A limiting bolt 606 that is inserted into the inserts 605 is threadedly installed on the top of the first clamping plate 601. The connection position can be limited by the cooperation of the slots 604, inserts 605 and limiting bolts 606, ensuring the strength of the clamping limit and making it easy to operate.

[0021] In the embodiments of this utility model, the opposing surfaces of the two support plates 501 are provided with sliding grooves 506, and the opposing sides of the second clamping plate 602 are fixedly provided with T-shaped sliding plates 607 that slide with the second clamping plate 602; the sliding range of the second clamping plate 602 can be limited by the cooperation, and it is not easy to detach from the support plate 501.

[0022] In the embodiments of this utility model, a plurality of hemispherical support protrusions 504 are fixedly provided on the top side of each groove 503, and a through hole 505 is provided through the center of the groove 503; the support protrusions 504 can expand the contact range between the bottom of the bottle and hot water, and the through hole 505 can facilitate the flow of hot water, and the spray sterilization effect is not affected when the bottle is turned over.

[0023] In this embodiment of the present invention, a heating rod 201 is fixedly installed inside the hot water tank 2, and a drain plate 202 is fixedly installed on the top of the hot water tank 2. Both sides of the drain plate 202 are equipped with bent pipes 203 that pass through the side wall of the sterilizer 1, and one side of the bent pipe 203 is fixedly connected to the pumping mechanism 3. By cooperating, the hot water after spraying can be easily recovered, achieving a continuous heating effect and maintaining the stability of the hot water sterilization temperature.

[0024] Working Principle: This embodiment provides a water bath sterilizer for storing traditional Chinese medicine. In use, firstly, an appropriate amount of clean water is injected into the hot water tank 2 at the bottom of the sterilizer 1's inner cavity through an external water pipe connected to the curved pipe 203 on the side of the sterilizer 1. Then, the heating rod 201, fixedly installed inside the hot water tank 2, is activated. After being energized, the heating rod 201 converts electrical energy into heat energy, heating the water until the water temperature reaches the set temperature required for sterilizing the traditional Chinese medicine (usually 80-121℃ for high-temperature sterilization, adjusted according to the characteristics of the traditional Chinese medicine). After the hot water is prepared, the water pumping mechanism 3, fixedly connected to the outer side of the hot water tank 2, is activated. The pumping end of the mechanism 3, connected to the curved pipe 203, draws hot water into the hot water tank 2, which is then transported through a pipe to the spray box 4 fixedly installed at the top of the sterilizer 1's inner cavity, forming the initial hot water circulation path. The operator places the medicine bottle containing the traditional Chinese medicine liquid onto the tray 502 of the flipping frame 5. Several grooves 503 on the top of the tray 502 are used to restrict the bottom position of the medicine bottle, preventing it from shifting laterally during the flipping process. Simultaneously, a hemispherical support protrusion 504 fixed to the top side of each groove 503 reduces the contact area between the bottom of the medicine bottle and the groove 503, allowing the subsequent hot water spray to more fully contact the bottom of the bottle. A through-hole 505 in the center of the groove 503 allows for timely drainage of accumulated hot water, preventing uneven water temperature. The clamping assembly 6 on the flipping frame 5 is adjusted according to the diameter of the medicine bottle. First, loosen the limiting bolt 606 at the top of the first clamping plate 601, and push the second clamping plate 602 to slide along the sliding groove 506 on the opposite side of the support plate 501. The T-shaped sliding plate 607 on the opposite side of the second clamping plate 602 slides and engages with the sliding groove 506 to ensure sliding stability and make the distance between the second clamping plate 602 and the first clamping plate 601 suitable for the diameter of the medicine bottle. Then, place the medicine bottle body into the clamping groove 603 of the first clamping plate 601, and push the second clamping plate 602 so that the clamping groove 603 of the second clamping plate 602 engages with the clamping groove 603 of the first clamping plate 601 to wrap around the bottle body (the inner edge of the clamping groove 603 is petal-shaped, which can increase the contact area with the bottle body and avoid damaging the bottle body). Finally, tighten the limiting bolt 606 so that it is tightly inserted into the insert 605 on the side of the second clamping plate 602 and the slot 604 on the side of the first clamping plate 601 to complete the fixation of the medicine bottle body. The drive motor 7, fixedly mounted on the side of the sterilizer 1 away from the water pumping mechanism 3, is activated. The output shaft of the drive motor 7 is fixedly connected to the support plate 501 of the rotating frame 5 on the same side. When the motor runs, it drives the support plate 501 and the entire rotating frame 5 to rotate around the rotation connection point between the support plate 501 and the sterilizer 1. The rotation speed can be adjusted according to the sterilization requirements (usually a low-speed, uniform rotation to ensure that the liquid in the bottle is fully heated). While the rotating frame 5 rotates, the water pumping mechanism 3 continuously delivers high-temperature hot water from the hot water tank 2 to the spray box 4. The spray box 4, through the spray holes at the bottom (not clearly marked), is a conventional structure of the spray assembly, which evenly sprays high-temperature hot water onto the surface of the liquid bottle during the rotation process.As the rotating frame 5 continuously rotates, each side of the medicine bottle alternately contacts the high-temperature hot water, preventing localized insufficient heating. Simultaneously, the medicine inside the bottle flows continuously due to the rotating action, further ensuring uniform internal temperature and meeting sterilization requirements. The hot water sprayed onto the surface of the medicine bottle drips downwards under gravity, landing on the drain plate 202 at the top of the hot water tank 2. The perforated structure of the drain plate 202 allows hot water to pass through, causing it to flow back into the hot water tank 2, preventing waste.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
