Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment, and in particular to a vacuum device for accelerating the drying of traditional Chinese medicine extracts. Background Technology

[0002] In the process of modernizing the production of traditional Chinese medicine, the drying process of Chinese medicine extracts is crucial, as it directly affects the quality, stability, and production efficiency of Chinese medicine products. In order to better dry Chinese medicinal materials, vacuum drying equipment for Chinese medicine has emerged.

[0003] In existing technologies, common vacuum drying equipment for traditional Chinese medicine (TCM) typically controls the temperature and vacuum level precisely to dry the herbs. However, in practice, drying a batch of TCM extracts usually takes more than 20 hours. For some TCM materials with special properties, high moisture content, or complex compositions, the drying time can even exceed 40 hours. This extended drying time directly leads to a longer production cycle, reduced product output per unit time, and a significant decrease in production efficiency. Moreover, during the prolonged drying process, some active ingredients in the TCM extracts may undergo decomposition, oxidation, or other chemical reactions due to prolonged exposure to high temperatures or specific environments, thereby reducing the quality and efficacy of the TCM. Therefore, there is a need to improve the vacuum equipment to accelerate the drying of TCM extracts and solve these problems. Utility Model Content

[0004] To overcome the problem that traditional drying processes, which rely on controlling temperature and vacuum, take a long time to process and thus affect overall production efficiency in actual use.

[0005] The technical solution of this utility model is as follows: a vacuum device for accelerating the drying of traditional Chinese medicine extracts, including an installation ground, an air compressor body and a placement mechanism, a support base for support on the installation ground, a device housing fixedly connected to the top of the support base, a placement mechanism for placing medicinal materials inside the device housing, an air compressor body for compressing air on the installation ground, a first connecting pipe for conveying air fixedly connected between the air compressor body and the device housing, a pulse valve body on the first connecting pipe, a main vacuum valve body for extracting air on the installation ground, a second connecting pipe fixedly connected between the main vacuum valve body and the device housing, a first fixed seat fixedly connected to the device housing, a secondary vacuum valve body for extracting air on the first fixed seat, a vacuum gauge body for detecting vacuum degree on the device housing, and a controller body for controlling the start of the secondary vacuum valve body on the device housing.

[0006] Preferably, a cabinet door for sealing the device housing is rotatably connected to the device housing, a first fixing buckle is fixedly connected to the device housing, a rotating rod is rotatably connected to the first fixing buckle, a second fixing buckle is fixedly connected to the cabinet door, a first threaded rod is rotatably connected to the rotating rod, a first knob is fixedly connected to one end of the first threaded rod, a sliding bracket is threadedly connected to the first threaded rod, the sliding bracket is slidably connected inside the rotating rod, and a clamping rod is fixedly connected to one end of the sliding bracket.

[0007] Preferably, the cabinet door is equipped with a sealing gasket for sealing, and the cabinet door seals the outer casing of the device through the sealing gasket.

[0008] Preferably, the rotating rod has a groove at a position relative to the first threaded rod, and the first threaded rod is rotatably connected inside the groove.

[0009] Preferably, the rotating rod has a groove at the relative position of the sliding bracket, and the sliding bracket is slidably connected inside the groove.

[0010] Preferably, the placement mechanism includes a fixed frame, which is fixedly connected inside the device housing. A support wheel is rotatably connected to the fixed frame. A sliding frame is slidably connected inside the fixed frame. A placement frame is fixedly connected inside the sliding frame. A heat-conducting plate is fixedly connected to the device housing.

[0011] Preferably, the fixed frame has a groove at the relative position of the sliding frame, and the sliding frame is slidably connected inside the groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. Compared to traditional drying methods that rely on temperature and vacuum control, this method uses a main vacuum valve to create a vacuum environment while simultaneously injecting pulsed airflow into the device's casing via an air compressor and pulse valve. This accelerates gas flow within the casing, reducing drying time and improving production efficiency. It also enhances the drying effect and overall quality of the medicinal materials, preventing insufficient drying from negatively impacting subsequent use. This avoids the problem of long processing times and reduced overall production efficiency associated with traditional temperature and vacuum control methods.

[0014] 2. The vacuum level between the internal partitions of the device housing is detected by the vacuum gauge body and the signal is transmitted to the controller body. The controller body then controls the auxiliary vacuum valve body to work, which in turn assists the main vacuum valve body in controlling the vacuum level between the internal partitions of the device housing. According to the different drying requirements of Chinese medicinal materials, the vacuum level between the internal partitions of the device housing is controlled in a gradient manner to better improve the drying effect of Chinese medicinal materials.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1 - Figure 4This utility model provides an embodiment of a vacuum device for accelerating the drying of traditional Chinese medicine extracts, including an installation ground 5, an air compressor body 21, and a placement mechanism. A support base 4 is provided on the installation ground 5, and a device housing 1 is fixedly connected to the top of the support base 4. A placement mechanism for placing medicinal materials is provided inside the device housing 1. The air compressor body 21 for compressing air is provided on the installation ground 5, and a first connecting pipe 22 for conveying air is fixedly connected between the air compressor body 21 and the device housing 1. A pulse valve body 23 is provided on the first connecting pipe 22. A main vacuum valve body 24 for extracting air is provided on the installation ground 5, and a second connecting pipe 25 is fixedly connected between the main vacuum valve body 24 and the device housing 1. A first fixed base 26 is fixedly connected to the device housing 1, and a secondary vacuum valve body 27 for extracting air is provided on the first fixed base 26. A vacuum gauge body 28 for detecting vacuum level is provided on the device housing 1, and a controller body 29 for controlling the start of the secondary vacuum valve body 27 is provided on the device housing 1. The specific model of the controller body 29 is S7-200. In SMART, after placing the medicinal materials inside the placement mechanism, the outer casing 1 of the device is sealed. The main vacuum valve body 24 operates to extract the air inside the outer casing 1, creating a vacuum environment. Then, the air compressor body 21 operates to extract and compress the air, which is then delivered to the inner casing 1 through the first connecting pipe 22 and the pulse valve body 23 to form a pulsed airflow, thereby accelerating the gas flow inside the outer casing 1. The vacuum gauge body 28 operates to detect the vacuum degree of each compartment of the outer casing 1 and transmits the signal to the controller body 29. When the vacuum degree does not reach the appropriate standard, the controller body 29 operates to activate the auxiliary vacuum valve body 27 to extract the air inside the outer casing 1, thereby ensuring that the vacuum degree between the compartments of the outer casing 1 meets the standard.

[0025] Please see Figure 1 - Figure 5In this embodiment, a sealing door 210 for sealing the device housing 1 is rotatably connected to the device housing 1. A first fixing buckle 211 is fixedly connected to the device housing 1, and a rotating rod 212 is rotatably connected to the first fixing buckle 211. A second fixing buckle 213 is fixedly connected to the sealing door 210. A first threaded rod 214 is rotatably connected to the rotating rod 212. A first knob 215 is fixedly connected to one end of the first threaded rod 214. A sliding bracket 216 is threadedly connected to the first threaded rod 214. The sliding bracket 216 is slidably connected inside the rotating rod 212. A clamping rod 217 is fixedly connected to one end of the sliding bracket 216. By rotating the first knob 215, the position of the clamping rod 217 is adjusted. The clamping rod 217 cooperates with the second fixing buckle 213 to restrict the rotation of the sealing door 210, thereby further maintaining the vacuum inside the device housing 1 and preventing air from entering due to the sealing door 210 not being completely closed, which would affect the drying rate of the medicinal materials. A sealing gasket is provided on the door 210 for sealing. The sealing door 210 seals the outer casing 1 of the device through the sealing gasket, and seals the gap between the sealing door 210 and the outer casing 1 of the device to prevent air from entering the interior of the outer casing 1 through the gap between the sealing door 210 and the outer casing 1 of the device. The rotating rod 212 has a groove at the relative position of the first threaded rod 214. The first threaded rod 214 is rotatably connected inside the groove. The groove restricts the rotation of the first threaded rod 214 and prevents the first threaded rod 214 from disengaging from the rotating rod 212 when rotating, which would affect the movement of the adjusting sliding bracket 216. The rotating rod 212 has a sliding groove at the relative position of the sliding bracket 216. The sliding bracket 216 is slidably connected inside the sliding groove. The sliding groove restricts the sliding of the sliding bracket 216, so that the sliding bracket 216 slides linearly inside the rotating rod 212 and prevents the sliding bracket 216 from disengaging from the rotating rod 212, which would affect its restriction on the sealing door 210.

[0026] Please see Figure 3 , Figure 6 - Figure 7In this embodiment, the placement mechanism includes a fixed frame 31, which is fixedly connected to the inside of the device housing 1. A support wheel 32 is rotatably connected to the fixed frame 31. A sliding frame 33 is slidably connected inside the fixed frame 31. A placement frame 34 is fixedly connected inside the sliding frame 33. A heat-conducting plate 35 is fixedly connected to the device housing 1. A heating wire body 36 for heating is provided on the device housing 1. A cover plate 37 is rotatably connected to the sliding frame 33. A first fixing block 38 is fixedly connected to the sliding frame 33. A sliding block 39 is slidably connected to the first fixing block 38. A first spring 310 is fixedly connected between the sliding block 39 and the first fixing block 38. A second fixing block 311 is fixedly connected to the cover plate 37. A sliding block 39 is snapped into the inside of the second fixing block 311. The first spring 310 provides a pushing force to the sliding block 39, making it more securely snapped into the inside of the second fixing block 311, thus restricting the rotation of the cover plate 37. The fixing frame 31 has a groove at the relative position of the sliding frame 33. The sliding frame 33 is slidably connected inside the groove. The groove restricts the sliding of the sliding frame 33, preventing the sliding frame 33 from detaching from the fixing frame 31 when sliding. When picking up materials, the sliding frame 33 slides to drive the placement frame 34 to the outside, thus making it easier for staff to pick up the dried medicinal materials.

[0027] During operation, after opening the cabinet door 210, pull out the sliding frame 33, then move the sliding block 39 to release it from the second fixing block 311, rotate the cover plate 37 to open it, place the medicine inside the placement frame 34, close the cover plate 37, and release the sliding block 39. The first spring 310 provides a pushing force to the sliding block 39, pushing it to re-engage with the second fixing block 311, thus restricting the second fixing block 311. Then, push the sliding frame 33 back into the device. After the outer casing 1 is inside, close the sealing door 210 and then rotate the rotating rod 212 to the inside of the second fixing buckle 213. Rotating the first knob 215 drives the first threaded rod 214 to rotate. When the first threaded rod 214 rotates, it drives the sliding bracket 216 to slide inside the rotating rod 212. After the clamping rod 217 with one end of the sliding bracket 216 is pressed against the second fixing buckle 213, the rotation of the sealing door 210 is restricted, thus sealing the outer casing 1. The outer casing 1 is then sealed for drying, first by heating the electric... The silk body 36 generates heat during operation, which is transferred to the placement frame 34 via the heat conduction plate 35 to heat the medicinal materials inside and evaporate their moisture. After the main vacuum valve body 24 operates, it extracts the air inside the device housing 1, creating a vacuum environment inside the device housing 1. Then, the air compressor body 21 operates to extract and compress the air, which is then delivered to the device housing 1 via the first connecting pipe 22 and the pulse valve body 23 to form a pulsed airflow, thereby accelerating the gas flow inside the device housing 1. The vacuum measuring instrument body 28 operates to detect the vacuum degree of each compartment of the device housing 1 and transmits the signal to the controller body 29. When the vacuum degree does not reach the appropriate standard, the controller body 29 operates to activate the auxiliary vacuum valve body 27 to extract the air inside the device housing 1, thereby making the vacuum degree between the compartments of the device housing 1 reach the standard. After the drying process is completed, when the first knob 215 is turned, the clamping rod 217 releases the contact with the second fixing buckle 213. Then, the cabinet door 210 is turned, the sliding frame 33 is pulled out, and the medicinal materials are taken out to complete the processing.

[0028] Through the above steps, compared with the drying process of controlling temperature and vacuum degree by transmission, while the main vacuum valve body 24 draws air to form a vacuum environment, the air compressor body 21 and the pulse valve body 23 inject pulse airflow into the device housing 1, so as to solve the problem that the traditional drying process of controlling temperature and vacuum degree has a long processing time in actual use, which affects the overall production efficiency.
