Description

Technical Field

[0001] This invention relates to the field of sterilization technology for Chinese medicinal materials, specifically a pressure steam sterilization device for Chinese medicinal materials. Background Technology

[0002] Sterilization is a crucial step in the processing and production of traditional Chinese medicinal materials to ensure their safety and efficacy. For example, Coptis chinensis (Huanglian) is a commonly used medicinal herb, primarily containing alkaloids such as berberine, and possesses properties such as clearing heat and dampness, purging fire and detoxifying. Coptis chinensis extract has wide applications in pharmaceuticals, health products, and cosmetics. Sterilization is necessary during its extraction; however, existing technologies still have some shortcomings in practical application, mainly in the following aspects.

[0003] Traditional pressure steam sterilization equipment typically employs a static sterilization method, where the medicinal herbs remain stationary during sterilization. This results in uneven contact between the steam and the herbs, leading to unsatisfactory sterilization results. This is particularly problematic for irregularly shaped or thickly stacked medicinal herbs, where the inner parts may not receive sufficient steam contact, further affecting sterilization. Therefore, this paper proposes a pressure steam sterilization device for medicinal herbs to address these issues. Summary of the Invention

[0054] 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.

[0055] Please see Figure 1-9 One embodiment of the present invention is: a pressure steam sterilization device for traditional Chinese medicinal materials, comprising a steam sterilization cylinder 1, and further comprising:

[0056] The lid 2 is positioned above the steam sterilization cylinder 1 and is used to seal the steam sterilization cylinder 1.

[0057] Rotating mechanism 3 is installed on the inner wall of steam sterilization cylinder 1 and is used to turn the Chinese medicine.

[0058] The pressure relief mechanism 4 is located above the cover 2 and is used to relieve pressure inside the steam sterilization cylinder 1;

[0059] The rotating mechanism 3 includes:

[0060] Placement ring 33 is fixedly connected to the inner wall of steam sterilization cylinder 1;

[0061] Multiple placement cylinders 31 are stacked sequentially on the inner wall of the steam sterilization cylinder 1, and the bottom placement cylinder 31 is rotatably connected to the placement ring 33;

[0062] A stirring component is installed on the inner wall of the steam sterilization cylinder 1 and is used to stir the Chinese medicine in the placement cylinder 31.

[0063] The placement cylinder 31 has a cylindrical hollow mesh structure, and the top cover plate of the placement cylinder 31 is separated from the cylinder body. The outer wall of the placement cylinder 31 has an annular placement hole for placing Chinese medicine.

[0064] A rotating shaft 7 is rotatably connected to the bottom of the inner wall of the steam sterilization cylinder 1. The rotating shaft 7 is hexagonal and is inserted into the inner wall of the placement cylinder 31 to drive the placement cylinder 31 to rotate.

[0065] There are two rotating shafts 7. The other rotating shaft 7 is rotatably connected to the cover 2. A motor is installed on the top of the cover 2. The output end of the motor is connected to the upper rotating shaft 7. The bottom of the upper rotating shaft 7 is inserted into the placement ring 33 to drive the placement ring 33 to rotate.

[0066] The bottom of the placement cylinder 31 is equipped with multiple spherical slide rods 32, and the top of the placement ring 33 and the placement cylinder 31 are provided with annular grooves, and the spherical slide rods 32 slide within the annular grooves.

[0067] The toggle assembly includes:

[0068] The multi-segment insertion rod 34 is inserted into the inner wall of the steam sterilization cylinder 1;

[0069] The connecting rod 35 is fixedly connected to the insert rod 34, and one side of the connecting rod 35 extends to the inner wall of the placement cylinder 31 for moving the Chinese medicine inside the placement cylinder 31.

[0070] The fixing sleeve 38 is fixedly connected to the other end of the connecting rod 35;

[0071] A ball-shaped rod 37 is movably connected to the inner wall of the fixed sleeve 38, and a spring 39 is sleeved on the outer wall of the ball-shaped rod 37 for pushing the ball-shaped rod 37 upward.

[0072] The wave-shaped pusher 36 is fixedly connected to the inner wall of the placement ring 33, and the wave-shaped surface of the wave-shaped pusher 36 contacts the ball rod 37 to resist the downward movement of the ball rod 37.

[0073] The bottom of the ball-shaped rod 37 is hinged with two levers 310 for moving the Chinese medicine.

[0074] A second lever 311 is hinged to the end of lever 310 away from the ball-shaped lever 37, and lever 311 is attached to the bottom of the placement cylinder 31 for moving the Chinese medicine.

[0075] Working principle: When sterilizing Chinese medicine with pressure steam, the cylinder 5 is started first. At this time, the cylinder 5 pushes the cooling cylinder 41 upward and disconnects the connection between the fixing rod 6 and the steam sterilization cylinder 1. Then, the entire top of the lid 2 is removed from the steam sterilization pot 1.

[0076] Then, the placement cylinder 31 is fitted onto the inner wall of the lower rotating shaft 7 and rotated on the placement ring 33 via the ball rod 37. Then, the actuating component is installed into the steam sterilization cylinder 1 via the insertion rod 34. Then, the upper cover plate of the steam sterilization cylinder 1 is fitted onto the lower rotating shaft 7 and installed in sequence. After installation, the cover 2 and its pressure relief mechanism 4 are inserted into the inner wall of the placement cylinder 31 via the upper rotating shaft 7 and fixed by the two fixing rods 6.

[0077] Then, by starting the motor, the upper motor drives the upper rotating shaft 7 to rotate, which in turn drives the uppermost placement cylinder 31 to rotate. Simultaneously, the lower rotating shaft 7 rotates, driving multiple placement cylinders 31 to rotate. At this time, the placement cylinders 31 rotate relative to the actuating assembly. When the wave-shaped push block 36 rotates, the crest of its wave-shaped groove surface touches the spherical rod 37, squeezing the spherical rod 37 downward. When the trough of the wave-shaped groove surface touches the spherical rod 37, the spring 39 pushes the spherical rod 37 upward, thereby synchronously driving the two levers 310 to move up and down, achieving the purpose of actuating the Chinese medicine. At the same time, during the up and down movement, lever 310 pushes lever 311 to move, thereby changing the actuating state and achieving the purpose of actuating the Chinese medicine, improving the actuating effect, promoting the contact between steam and Chinese medicine, improving the sterilization effect, and making the sterilization more thorough.

[0078] Please see Figure 1-9 Based on the above embodiments, in another embodiment of the present invention, the pressure relief mechanism 4 includes:

[0079] Cooling cylinder 41 is disposed above cover 2, and cooling cylinder 41 is annular;

[0080] Distillation tank 42 is located on the inner wall of cooling cylinder 41 and is used to store distilled water;

[0081] Multiple connecting blocks 43 are connected to the upper, lower and right side walls of the distillation tank 42, and to the inner wall of the cooling cylinder 41;

[0082] Multiple conduits 44 are connected at one end to the top of the cover 2, and at the other end are fixed through the cooling cylinder 41 and the distillation tank 42.

[0083] One end of the conduit 44 is tapered and is mounted on the cover 2 to collect steam and pass it into the distillation tank 42 through the conduit 44.

[0084] Pressure relief mechanism 4 also includes:

[0085] A pressure relief valve is installed on the outer wall of the cooling cylinder 41 and connected to the main pipe 44 inside the distillation tank 42 to release internal gas pressure.

[0086] Push ring 46 is installed inside distillation tank 42;

[0087] A high-pressure nozzle 45 is installed on the distillation tank 42 and extends through the cooling cylinder 41 and the cover 2 into the steam sterilization cylinder 1;

[0088] Push rod 47 is fixedly connected above push ring 46, and push rod 47 moves through distillation tank 42 and cooling cylinder 41 and extends upward;

[0089] The return spring 48 is sleeved on the outer wall of the push rod 47 and is used to return the push rod 47 upward.

[0090] Cylinders 5 are installed on the left and right sides of the outer wall of the steam sterilization cylinder 1, and the output end of the cylinder 5 is connected to the outer wall of the cooling cylinder 41 to push the cooling cylinder 41 and the cover 2 upward.

[0091] A push plate 49 is provided on the top of the steam sterilization cylinder 1, and two fixing rods 6 are fixedly connected to the bottom of the push plate 49, and the bottom of the fixing rods 6 is connected to the outer wall of the steam sterilization cylinder 1.

[0092] The bottom of the push plate 49 fits against the top of the push rod 47 to push the push rod 47 downward.

[0093] Working principle: During sterilization, the steam inside the steam sterilization cylinder 1 evaporates and enters the area above the lid 2, increasing the pressure inside the entire steam sterilization cylinder 1. After steam sterilization is completed, the pressure relief valve is opened, releasing the pressure inside the steam sterilization cylinder 1. The gas pressure inside the steam sterilization cylinder 1 enters the distillation tank 42 through the conduit 44, and after entering the cooling cylinder 41, it is cooled down, thereby condensing the steam. It then enters the distillation tank 42 for storage through the obliquely arranged conduit 44. Furthermore, the cylinder 5 moves upward by activation. At this time, the entire cover 2 and cooling cylinder 41 will be pushed upward, and the push rod 47 will be pushed upward to contact the push plate 49, thereby squeezing the push rod 47. At this time, the push rod 47 will push the push ring 46 downward, thereby squeezing the distilled water stored in the distillation tank 42 and squeezing it through the high-pressure nozzle 45. The high-pressure nozzle 45 will then spray the distilled water out and into the inner wall of the steam sterilization cylinder 1, thereby spraying distilled water onto the items inside the steam sterilization cylinder 1 and cooling them down, so as to facilitate the removal of the items inside and improve work efficiency.
