Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical moistening equipment technology, specifically to a vacuum heating moistening device. Background Technology

[0002] In traditional Chinese medicine and pharmaceuticals, "moistening" is a specific process or technique, primarily referring to the process of hydrating medicinal herbs. This process typically aims to alter certain physical properties of the herbs, such as hardness, toughness, or water absorption, to facilitate subsequent cutting, pulverizing, or other processing operations. The purpose of moistening is to bring the herbs to a suitable processing state while preserving as much of their medicinal components as possible. Vacuum moistening is a modern technique for moistening traditional Chinese medicine. Because the pressure is lower than atmospheric pressure in a vacuum environment, the air inside the herb is extracted, creating a pressure difference. This pressure difference allows the moistening liquid to penetrate the herb more easily. Compared to traditional moistening methods, this special pressure environment allows the moistening liquid to enter the intercellular spaces and internal tissues of the herb more quickly and evenly, significantly improving moistening efficiency.

[0003] In the prior art, for example, a patent application with application number CN201920022511.1 discloses "a vacuum moistening machine, including a rectangular moistening box, a steam inlet on the upper left outer wall of the moistening box, a steam inlet pipe connected to one end of the steam inlet, and a U-shaped steam conveying pipe connected to the other end of the steam inlet; multiple steam outlet pipes symmetrically arranged on both sides of the U-shaped steam conveying pipe; a rotating shaft inside the moistening box, the upper end of the rotating shaft being fixedly connected to the power output shaft of a motor via a coupling; multiple medicine trays on both sides of the outer wall of the rotating shaft; and a vacuum pipe connected to a vacuum pump on the lower left side of the moistening box. By setting medicine trays on the rotating shaft and driving them to rotate by a motor, and symmetrically setting steam outlets at a certain angle to the horizontal plane next to the rotating shaft, the medicinal materials under vacuum are fully contacted with steam, thus completing the moistening process."

[0004] Although this device uses steam ejected from a steam outlet to moisten the herbs, it lacks a liquefied water collection or treatment system. When steam enters the moistening tank, some of it liquefies into water, mixing with impurities from the herbs' surface and accumulating at the bottom of the tank. If this liquefied water remains inside for an extended period, it can easily breed bacteria, mold, and other microorganisms, leading to herb contamination. Furthermore, excessive water accumulation can negatively impact the humidity level of the herbs and the moistening effect. Therefore, a novel moistening device is needed to address these issues.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] In view of at least one of the above technical problems, this disclosure provides a vacuum heating and moistening device, which aims to solve the problem that the existing moistening devices cannot handle the liquefied water in the tank in a timely manner.

[0007] According to one aspect of this disclosure, a vacuum heating and moistening device for medicinal materials is provided, comprising a vacuum chamber, a front door movably mounted at the front end of the vacuum chamber, a main shaft rotatably mounted inside the vacuum chamber, a tray for placing medicinal materials fixedly sleeved on the main shaft, and a heating chamber disposed inside the vacuum chamber for heating.

A shaft motor fixed to the vacuum chamber is connected to the upper end of the main shaft. The shaft motor drives the main shaft, indirectly causing the rotation of the medicinal materials on the tray.

[0008] In some embodiments of this disclosure, the vacuum chamber further includes a water outlet at its bottom, a water injection pipe extending into the steam channel and disposed at the back of the vacuum chamber, and a motor housing covering the rotating shaft motor. The water injection pipe allows lubricating solution to be injected into the steam channel.

[0009] In some embodiments of this disclosure, the steam passage is located on both sides and the bottom of the tray. A heating pipe is also provided at the bottom of the steam passage, and a steam port for inputting steam is provided between the steam passage and the tray. A cleaning plate is also installed on the outer side of the bottom of the steam passage. By using the steam passage and steam port in combination, steam can be recycled.

[0010] In some embodiments of this disclosure, the vacuum chamber further includes a filter screen located at the lower end of the main shaft for recovering liquefied water, a recovery chamber fixed to the bottom of the filter screen for storing liquefied water, and purification screens located on the upper sides of the recovery chamber for filtering liquefied water. A processing switch is also provided at the bottom of the recovery chamber. The recovery chamber allows for timely collection and processing of liquefied water, and the continuously increasing liquefied water can be filtered through the purification screens and then flow into the steam channel for reuse.

[0011] In some embodiments of this disclosure, the heating box is installed on the left and right side walls of the tray, and a heating rod is also provided inside the heating box. The heating box can maintain a stable temperature in the wet medicine environment.

[0012] In some embodiments of this disclosure, the tray is further provided with a circulating fan for accelerating steam circulation, the circulating fan being rotatably fixed to the inner wall of the vacuum chamber.

[0013] In some embodiments of this disclosure, the front door is further provided with a pressure gauge for detecting the air pressure inside the vacuum chamber and a viewing window for observing the moistening process of the medicinal materials inside the vacuum chamber. The parameters displayed by the pressure gauge, in conjunction with the vacuum tube, can control the stability of the negative pressure inside the vacuum chamber, thereby ensuring the effective moistening of the medicinal materials.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0015] 1. The device of this application uses a steam channel in conjunction with a circulating fan to drive steam circulation to moisten the medicinal materials on the tray; at the same time, the rotatable tray, combined with the circulating steam, can ensure efficient and uniform moistening, and the steam can be reused in the steam channel during the circulation process, avoiding waste of resources.

[0016] 2. The device in this application uses a filter screen in conjunction with a recovery chamber to recover and treat liquefied steam. Moreover, when the amount of liquefied water increases, it can be filtered through a purification screen and then circulated back into the steam channel for reuse. This not only saves resources but also prevents excessive liquefied water from affecting the moistening effect of the medicine. At the same time, the device is easy to clean. After use, the cleaning plate is removed, and the plugs at the water outlet and the treatment switch are pulled out to collect and treat the liquefied water and moistening water stored inside. Then, the device can be rinsed and disinfected. Timely cleaning can prevent liquefied water from staying in the device for a long time and breeding bacteria, mold and other microorganisms, ensuring the hygiene and safety of the medicinal materials during the use of the device.

[0023] This application provides a vacuum heating and moistening device, which solves the problem that existing moistening devices cannot handle liquefied water in the tank in a timely manner. To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] This example discloses a vacuum heating and moistening device for medicine. See [link to relevant documentation]. Figures 1-4 The device includes a vacuum chamber 1, a front door 7 movably mounted at the front end of the vacuum chamber 1, a main rotating shaft 3 rotatably mounted inside the vacuum chamber 1, a tray 2 fixedly mounted on the main rotating shaft 3 for placing medicinal materials, and a heating chamber 4 located inside the vacuum chamber 1 for heating. A steam channel 14 for conveying steam is also provided inside the vacuum chamber 1. A vacuum tube 12 for extracting air from the vacuum chamber 1 is also installed on the back of the vacuum chamber 1. A rotating shaft motor 31, fixed to the vacuum chamber 1, is connected to the upper end of the main rotating shaft 3. The rotating shaft motor 31 drives the main rotating shaft 3, indirectly causing the rotation of the medicinal materials on the tray 2.

[0025] The vacuum chamber 1 also includes a water outlet 11 at its bottom, a water injection pipe 13 extending into the steam channel 14 and located at the back of the vacuum chamber 1, and a motor housing 19 covering the rotating shaft motor 31. The water injection pipe 13 can be used to inject a moistening solution into the steam channel 14. The steam channel 14 is located on both sides and the bottom of the tray 2. A heating pipe 5 is also located at the bottom of the steam channel 14. A steam port 18 for inputting steam is also located between the steam channel 14 and the tray 2. A cleaning plate 141 is also installed on the outer side of the bottom of the steam channel 14. The steam channel 14 and the steam port 18 work together to achieve steam recycling. The vacuum chamber 1 also includes a filter screen 17 located at the lower end of the main rotating shaft 3 for recovering liquefied water, a recovery chamber 15 fixed at the bottom of the filter screen 17 for storing liquefied water, and purification screens 16 located on the upper sides of the recovery chamber 15 for filtering liquefied water. A processing switch 151 is also located at the bottom of the recovery chamber 15. The liquefied water can be collected and treated in a timely manner using the recovery chamber 15, and the continuously increasing liquefied water can also be filtered through the purification net 16 and flow into the steam channel 14 for reuse.

[0026] Heating chambers 4 are installed on the left and right side walls of tray 2, and heating rods 41 are also provided inside heating chambers 4. Heating chambers 4 can be used to maintain a stable temperature in the wet medicine environment.

[0027] The tray 2 is also equipped with a circulating fan 6 to accelerate steam circulation. The circulating fan 6 is rotatably fixed to the inner wall of the vacuum chamber 1. The circulating fan 6 can promote steam circulation and improve the efficiency of moistening the medicine.

[0028] The front door 7 is also equipped with a pressure gauge 71 for detecting the air pressure inside the vacuum chamber 1 and a viewing window 72 for observing the moistening of the medicinal materials inside the vacuum chamber 1. The parameters displayed by the pressure gauge 71, in conjunction with the vacuum tube 12, can control the stability of the negative pressure inside the vacuum chamber 1, thereby ensuring the effective moistening of the medicinal materials.

[0029] When implementing the device of this application, first open the front door 7 and evenly spread the medicinal materials to be moistened on the tray 2. The multi-layered tray 2 allows the device to simultaneously moisten a large quantity of medicinal materials. After the medicinal materials are laid out, open the water injection pipe 13 and inject a certain amount of moistening water into the steam channel 14, then close the water injection pipe 13 and the front door 7. Next, open the heating pipe 5 to heat the moistening water and generate steam, open the heating box 4 to raise the temperature of the environment inside the vacuum box 1, and turn on the rotating shaft motor 31 to drive the main rotating shaft 3 to rotate the medicinal materials on the tray 2. Turn on the circulating fan 6 to accelerate steam circulation; then connect the vacuum tube 12 to the vacuum pumping device and extract air from the vacuum chamber 1 to create negative pressure. When the negative pressure reaches a certain value, turn off the vacuum pumping device. At this time, the steam generated in the steam channel 14 inside the vacuum chamber 1 moves upward and enters the space where the tray 2 is located through the steam port 18. Then, the steam moves downward under the action of the circulating fan 6, simultaneously wetting the medicinal materials on the tray 2. Since the tray 2 is rotatable, the medicinal materials can be evenly moistened with the continuous injection of steam. Because the vacuum chamber 1 is a negative pressure environment and forms a pressure difference with the external atmospheric pressure, the moistening liquid can more easily penetrate into the inside of the medicinal materials under the action of the pressure difference. While the steam moves downward to moisten the medicinal materials, part of the steam liquefies on the surface of the medicinal materials and carries impurities on the surface of the medicinal materials through the filter screen 17 into the recovery chamber 15. The other part of the steam passes through the filter screen 17 and the purification screen 16 and re-enters the steam channel 14, and moistens the medicinal materials with the newly generated steam. This cyclical moistening improves work efficiency and saves resources. As the amount of liquefied water collected in the recovery chamber 15 gradually increases, the excess liquefied water is filtered through the purification screen 16 and flows into the bottom of the steam channel 14 for heating and evaporation by the heating tube 5. This cycle avoids excessive liquefied water affecting the humidity environment for moistening the herbs and allows for the reuse of the moistening water to avoid wasting resources. During the moistening process, the heating chamber 4 inside ensures that the temperature of the moistening environment remains at a suitable level. At the same time, based on the changes in parameters on the pressure gauge 71, the opening and closing of the vacuum device can be controlled to maintain the stability of the negative pressure inside the vacuum chamber 1, ensuring the quality of the moistening of the herbs. In addition, during the moistening process, the moistening status of the herbs inside the vacuum chamber 1 can be observed through the viewing window 72. After the medicinal materials have been moistened and collected, the device needs to be cleaned. First, remove the cleaning plate 141 and simultaneously open the processing switch 151 and the water outlet 11. Then, clean out the liquefied water stored in the recovery chamber 15 and the excess moistening water stored in the steam channel 14. Finally, rinse and disinfect the device. Timely cleaning can prevent the liquefied water from remaining for a long time and breeding bacteria, mold, and other microorganisms. In addition, the rotating shaft motor 31, circulating fan 6, heating rod 41, and heating tube 5 used in the device of this application are all existing technologies, and their specific working principles and control methods will not be described in detail in this technical solution.
