Description

Technical Field

[0001] This utility model relates to the field of steam sterilizer technology, specifically a vertical pressure steam sterilizer for testing traditional Chinese medicine. Background Technology

[0002] Pressure steam sterilizers play a crucial role in the testing of traditional Chinese medicine (TCM). They effectively kill microorganisms through high-temperature, high-pressure steam, ensuring the quality and safety of TCM products. During the production and testing of TCM, raw materials and samples may be contaminated by bacteria, fungi, viruses, and other microorganisms. Pressure steam sterilizers eliminate these potential sources of contamination, ensuring sample purity and avoiding deviations in test results due to contamination. Furthermore, pressure steam sterilizers can also be used to sterilize testing equipment, preventing cross-contamination and ensuring a sterile environment for experiments. Their core principle relies on steam penetrating materials under high temperature and pressure, destroying the cell walls, proteins, and nucleic acid structures of microorganisms, thereby achieving sterilization. The main structure of the equipment includes a sterilization chamber, a steam generator, a temperature and pressure regulation system, and safety protection devices. Steam is generated by heating water. After entering the sterilization chamber, the temperature and pressure gradually increase and are maintained for a certain period to ensure the complete killing of microorganisms. The steam is removed through an exhaust and cooling system to restore atmospheric pressure, completing the sterilization process. However, current steam sterilizers are mainly single-tank structures, with the medicinal materials to be sterilized piled at the bottom. Due to the time difference in steam conduction and distribution, the accumulation of materials at the bottom often prevents steam from penetrating evenly to every part. Even if the surface material reaches the high temperature required for sterilization, the deeper material may not reach the effective sterilization temperature, resulting in incomplete sterilization. This is especially true for some medicinal materials that are hard or contain a lot of fiber, where steam penetration is slow, making it very easy for some materials to fail to be completely sterilized. Utility Model Content

[0003] The purpose of this invention is to provide a vertical pressure steam sterilizer for testing traditional Chinese medicine. It consists of two interconnected symmetrical conical sterilization tanks. After the traditional Chinese medicine to be sterilized is placed into the two conical sterilization tanks, the air inlet valve sends high-pressure steam generated by the steam generator into the conical sterilization tanks. During the sterilization process, the direct drive motor and gear transmission structure cause the vertical shaft and spiral blades to continuously turn the traditional Chinese medicine upwards, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vertical pressure steam sterilizer for testing traditional Chinese medicine, comprising a convex base and conical sterilization tanks fixed on the outer walls of both sides of the convex base. The two conical sterilization tanks are interconnected. An air inlet valve and an external threaded plug are respectively installed on the outer walls of the two conical sterilization tanks on opposite sides. A discharge structure is installed at the bottom of each conical sterilization tank. A vertical shaft is rotatably installed at the center of the interior of each conical sterilization tank, and a bushing is fixed at one end of the surface of the vertical shaft. A spiral blade for turning the traditional Chinese medicine materials upward is fixed on the outer circumference of the bushing. A hollow sealing cover is fixed at the top of each of the two conical sterilization tanks. A gear transmission structure for driving the two vertical shafts to rotate synchronously is provided inside the hollow sealing cover. A direct drive motor for driving the gear transmission structure is installed at the center of the top of the hollow sealing cover.

[0005] Preferably, the discharge structure includes a discharge pipe fixed at the bottom opening of the conical sterilization tank and a butterfly valve at the bottom of the discharge pipe.

[0006] Preferably, the discharge pipe is equipped with an auger shaft inside, and the top end of the auger shaft is fixedly connected to the bottom end of the vertical shaft.

[0007] Preferably, the gear transmission structure includes a main shaft rotatably mounted at the center of the hollow sealing cover, a driving gear plate fixed at one end of the main shaft surface, and a driven gear plate fixed at the top of the vertical shaft. The driving gear plate and the driven gear plate mesh with each other, and the top of the main shaft is fixedly connected to the output shaft of the direct drive motor through a coupling.

[0008] Preferably, a dynamic seal is provided at the center of the top of the conical sterilization tank for sealing the conical sterilization tank and assisting the vertical shaft in rotation.

[0009] Preferably, the outer wall of the spiral blade is provided with a completely through hollow part, and the spiral blade and bushing are made of stainless steel components.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the vertical pressure steam sterilizer for testing Chinese medicine completes the sterilization of Chinese medicinal materials through a conical sterilization tank, an air inlet valve, a vertical shaft, a spiral blade, a direct drive motor, and a gear transmission structure. Steam enters the tank through the air inlet valve and heats the medicinal materials evenly, while the tumbling of the vertical shaft and the spiral blade ensures that the medicinal materials are fully and evenly sterilized in the tank.

[0011] The combination of a vertical shaft and spiral blades in the sterilization tank allows the medicinal herbs to be continuously agitated after being placed into the two conical sterilization vessels. This constant agitation changes the position of the herbs, ensuring that every part of the herbs comes into contact with steam, enhancing steam penetration, and achieving more comprehensive and uniform sterilization. This agitation structure is particularly important for some hard, fibrous medicinal herbs, as it helps steam penetrate deep into the herbs, improving the thoroughness of sterilization.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5This utility model provides an embodiment of a vertical pressure steam sterilizer for testing traditional Chinese medicine, including a convex base 1 and conical sterilization tanks 2 fixed on the outer walls of both sides of the convex base 1. The two conical sterilization tanks 2 are interconnected. An air inlet valve 5 and an external threaded plug 6 are respectively installed on the outer wall of the two conical sterilization tanks 2 on the side away from each other. The operator unscrews the external threaded plug 6 to allow the medicinal material to be processed to enter through the feed port on the outer wall of the conical sterilization tank 2. After the steam enters the two symmetrical conical tanks, the design of the conical tank body can be optimized and the steam can be evenly distributed.

[0020] The bottom of the cone-shaped sterilizer 2 is equipped with a discharge structure. A vertical shaft 10 is rotatably installed at the center of the inside of the cone-shaped sterilizer 2, and a bushing 12 is fixed to one end of the surface of the vertical shaft 10. A spiral blade 13 for turning the Chinese medicinal materials upward is fixed to the outer circumference of the bushing 12. A completely through-hole 1301 is provided on the outer wall of the spiral blade 13. The spiral blade 13 and the bushing 12 are made of stainless steel components.

[0021] Two conical sterilization tanks 2 are fixed with hollow sealing covers 7 at their top ends. The hollow sealing covers 7 are equipped with gear transmission structures 9 for driving the two vertical shafts 10 to rotate synchronously. A direct drive motor 8 for driving the gear transmission structure 9 is installed at the center of the top end of the hollow sealing covers 7.

[0022] The discharge structure includes a discharge pipe 3 fixed at the bottom opening of the conical sterilizer 2 and a butterfly valve 4 at the bottom of the discharge pipe 3. The discharge pipe 3 is equipped with an auger shaft 11. The top of the auger shaft 11 is fixedly connected to the bottom of the vertical shaft 10. After the discharge is completed, the operator opens the butterfly valve 4 to keep it in the normally open state. Then the direct drive motor 8 and the gear transmission structure 9 continue to drive the vertical shaft 10 and the auger shaft 11 to rotate. The auger shaft 11 actively conveys the medicinal materials in the conical sterilizer 2 downwards, so that the medicinal materials are discharged through the butterfly valve 4, which facilitates the feeding.

[0023] The gear transmission structure 9 includes a main shaft 901 rotatably installed at the center of the hollow sealing cover 7, an active gear 903 fixed at one end of the surface of the main shaft 901, and a driven gear 902 fixed at the top of the vertical shaft 10. The active gear 903 meshes with the driven gear 902. The top of the main shaft 901 is fixedly connected to the output shaft of the direct drive motor 8 through a coupling. The rotational power of the direct drive motor 8 is transmitted to the main shaft 901, and the main shaft 901 drives the driven gear 902 and the vertical shaft 10 to rotate through the active gear 903. At this time, the medicinal materials in the two conical sterilization tanks 2 are turned up by the spiral blades 13.

[0024] A dynamic seal 201 is provided at the center of the top of the conical sterilizer 2 to seal the conical sterilizer 2 and assist the vertical shaft 10 in rotation.

[0025] In this embodiment, before sterilization begins, the operator needs to check the working status of components such as the conical sterilization tank 2, the air inlet valve 5, the direct drive motor 8, and the gear transmission structure 9 to ensure there are no malfunctions and that the equipment is in standby mode. Next, the Chinese medicinal materials to be sterilized are placed into the two interconnected, symmetrical conical sterilization tanks 2. At this time, the medicinal materials are in a certain piled-up state. Once the conical sterilization tanks 2 are ready, the operator connects the air inlet valve 5 to an external steam generator, keeping the air inlet valve 5 in a normally open state. High-pressure steam is introduced from the steam generator into the conical sterilization tanks 2. The structural design of the conical sterilization tanks 2 allows the steam to better diffuse and cover all corners of the medicinal materials. The heating effect of the steam... The surface and interior of the medicinal materials are gradually heated, thereby killing bacteria, viruses and other microorganisms. Once steam begins to enter the conical sterilization tank 2, the staff starts the direct drive motor 8. The rotational power of the direct drive motor 8 is synchronously transmitted to the two vertical shafts 10 through the gear transmission structure 9. The vertical shafts 10 drive the bushings 12 and the spiral blades 13 to rotate. The spiral blades 13 continuously tumble and lift the medicinal materials, causing them to tumble inside the tank. Because the medicinal materials are constantly tumbling, each piece of medicinal material is exposed to the steam, preventing local overheating or underheating and avoiding incomplete sterilization due to uneven residence time. After a certain period of high-temperature steam treatment, the sterilization process is basically completed.
