Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical drying technology, and in particular to a drying device for pharmaceutical experiments. Background Technology

[0002] In the fields of pharmaceutical research and development and laboratories, different drugs are tested. Before researching traditional Chinese medicine, the raw materials need to be harvested and prepared. During the preparation process or after long-term storage, traditional Chinese medicine needs to be dried to remove moisture from the medicinal materials in order to prevent them from becoming moldy, deteriorating, losing their luster, or even losing their efficacy. Therefore, drying equipment is needed to dry the raw materials of traditional Chinese medicine that need to be studied.

[0003] Most small-scale TCM drying devices on the market can only perform the drying function, but their drying effect is not good. When there are a lot of medicinal materials, the materials will accumulate during the drying process, making it impossible to heat and dry the materials evenly. This will cause the medicinal materials to deteriorate during later research and storage, affecting their use. Therefore, we provide a drying device for pharmaceutical experiments to solve this problem. Utility Model Content

[0007] Preferably, the filtration mechanism includes a base disposed in the inner cavity of the top cover. The base is located at the upper end of the top plate, and the upper end of the base is provided with multiple sets of slots. The inner cavities of the slots are respectively inserted with a coarse filter screen, a fine filter screen, a filter cotton plate, and an activated carbon filter plate.

[0008] Preferably, the drying mechanism includes a fan shroud mounted on the upper part of the top plate. The fan shroud is located in the inner cavity of the top shroud.

Three sets of second air ducts are rotatably connected to the lower end of the support frame. Three sets of connecting pipes are connected to the lower end of the exhaust pipes. The lower ends of the three sets of connecting pipes are rotatably connected to the three sets of second air ducts respectively. Pulleys are mounted on the outer sides of both the first and second air ducts. A belt is sleeved on the outer side of the pulleys.

[0009] Preferably, multiple sets of heat dissipation fins are integrally connected to the outer sides of the first and second air ducts, and the first and second air ducts as well as the heat dissipation fins are all made of aluminum.

[0010] Preferably, the drug-carrying mechanism includes a drug-carrying tank disposed outside three sets of second air ducts and one set of first air ducts.

[0014] The drying device for pharmaceutical experiments proposed in this utility model has the following advantages:

[0015] 1. The herbs in the medicine-carrying tank of the drying mechanism are heated and dried while being turned over, which effectively improves the uniformity of drying of Chinese medicinal herbs. At the same time, the hot air in the first and second air ducts of the drying mechanism enters the support pipe of the air blowing component from its lower end, and then enters the L-shaped pipe. Therefore, the remaining hot air enters the inner cavity of the medicine-carrying tank through the L-shaped pipe and through hole, which facilitates the turning over of the herbs located at the bottom of the inner cavity of the medicine-carrying tank. This effectively improves the mixed drying effect of the herbs in the medicine-carrying tank and avoids the inability of some herbs to be turned over effectively, which would result in uneven heating and drying and affect the quality of the herbs in the later stages. It also makes it easier to utilize all the remaining heat in the air, further improving the efficiency of heating and drying.

[0016] 2. The electromagnetic vent valve is opened intermittently by an external controller at regular intervals to facilitate the removal of water vapor generated in the inner cavity of the chamber after heating and drying, which effectively improves the drying effect and avoids excessive humidity in the inner cavity of the chamber, which would reduce the drying effect.

[0017] 3. The coarse and fine filter plates of the filtration mechanism first filter and block large and small particles of debris in the air. Then, the filter cotton plate blocks and filters fine dust in the air. Finally, the activated carbon filter plate effectively purifies and filters the air, which effectively improves the layered filtration effect of the air. By pulling out the base, the coarse filter plate, fine filter plate, filter cotton plate and activated carbon filter plate are all inserted into the slots, which is convenient for installation, disassembly and replacement, and easy to use.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-8 A drying device for pharmaceutical experiments includes a housing 1, with a top plate 4 and a bottom plate 3 installed at the upper and lower ends of the housing 1, respectively. A door 2 is movably installed on the outside of the housing 1. A top cover 6 is installed on the upper end of the top plate 4, and an air inlet pipe 7 is connected to the outside of the top cover 6. A filter mechanism 10 is movably installed in the inner cavity of the top cover 6. The filter mechanism 10 includes a base 101 located in the inner cavity of the top cover 6, with the base 101 positioned above the top plate 4. The upper end of the base 101 has multiple sets of slots 107, and the inner cavities of the slots 107 are respectively inserted into a coarse filter screen 102, a fine filter screen 103, a filter cotton plate 104, and an activated carbon filter plate 105. A slider 106 is symmetrically connected to the lower end of the base 101, and two sets of sliding grooves 19 are provided on the upper end of the top plate 4 for sliding contact with it.

[0029] The air entering between the top cover 6 and the top plate 4 through the air intake pipe 7 is first filtered by the filter mechanism 10. Specifically, the coarse filter plate 102 and the fine filter plate 103 filter and block large and small particles in the air. Then, the filter cotton plate 104 blocks and filters fine dust in the air. Finally, the activated carbon filter plate 105 effectively purifies and filters the air, which effectively improves the layered filtration effect of the air. By pulling out the base 101, the slider 106 at the lower end of the base 101 slides within the inner cavity of the slide groove 19, which facilitates the stability of the push and pull movement of the base 101. The coarse filter plate 102, the fine filter plate 103, the filter cotton plate 104, and the activated carbon filter plate 105 are all inserted into the slots 107, which is convenient for installation, disassembly and replacement, and easy to use.

[0030] The inner cavity of the top cover 6 is equipped with two sets of partitions 14. The lower end of the partitions 14 is attached to the top plate 4. One of the partitions 14 has a slot on its outer side that corresponds to the position of the filter mechanism 10. A heating chamber 15 is formed between the two sets of partitions 14. Multiple heaters 16 are installed in the inner cavity of the heating chamber 15. The inner wall of the heating chamber 15 is coated with a heat insulation coating. A booster fan 17 is installed at the upper end of the top plate 4. One side of the booster fan 17 is connected to a partition 14 through a pipe. A drying mechanism 9 is installed at the upper end of the top plate 4. The lower end of the drying mechanism 9 passes through the top plate 4 and extends into the inner cavity of the box 1. One side of the booster fan 17 is connected to the drying mechanism 9 through a hose 18.

[0031] The drying mechanism 9 includes a fan shroud 91 mounted on the upper end of the top plate 4. The fan shroud 91 is located inside the top cover 6. One end of the flexible hose 18 is connected to the fan shroud 91. A support shaft 92 is rotatably connected to the inner cavity of the fan shroud 91. A fan 93 is mounted on the outer side of the support shaft 92. A first air duct 94 is mounted on the lower end of the support shaft 92. Air inlets 95 are equidistantly arranged on the upper outer side of the first air duct 94. The lower end of the first air duct 94 penetrates the top plate 4 and extends into the inner cavity of the housing 1. A support plate 96 is mounted in the inner cavity of the housing 1. An exhaust pipe 98 is mounted on the upper end of the support plate 96 via a support frame 97. One end of the exhaust pipe 98 penetrates the top plate 4 and extends into the fan shroud 91. The inner cavity of the support frame 97 is rotatably connected to three sets of second air ducts 910. The lower end of the air duct 98 is connected to three sets of connecting pipes 99. The lower ends of the three sets of connecting pipes 99 are rotatably connected to the three sets of second air ducts 910 respectively. The outer sides of the first air duct 94 and the second air duct 910 are both equipped with pulleys 911. The outer sides of the pulleys 911 are all sleeved with belts 912. The outer sides of the first air duct 94 and the second air duct 910 are equidistantly equipped with material turning plates 914. The outer sides of the first air duct 94 and the second air duct 910 are integrally connected with multiple sets of heat dissipation fins 913. The first air duct 94, the second air duct 910 and the heat dissipation fins 913 are all made of aluminum.

[0032] By starting the booster fan 17, air filtered by the filter mechanism 10 enters the heating chamber 15 through a slot on the outside of a partition 14. The air is heated by the heater 16 within the heating chamber 15. The insulation coating on the inner wall of the heating chamber 15 provides effective heat insulation, improving heating and heat preservation. A temperature sensor is designed in the upper center of the base plate 3. When this sensor detects excessively high temperatures inside the chamber 1, it feeds this information back to an external controller. The controller then automatically activates an external automatic temperature controller electrically connected to the heater 16, adjusting the heating temperature of the heater 16 to prevent overheating and loss of medicinal efficacy during high-temperature drying of traditional Chinese medicine, thus effectively improving the treatment effect. The booster fan 17 then draws the heated air into its inner chamber through a pipe and discharges it through a hose 18 to the impeller cover 91. The pressurized hot air then blows the impeller 93 inside the impeller cover 91. The impeller 93 drives the support shaft 92 and the first air duct 94 at its lower end to rotate. The pulley 911 on the outside of the first air duct 94 drives the other three sets of second air ducts 910, which are also equipped with pulleys 911, to rotate simultaneously via belt 912. Some hot air enters the inner cavity of the first air duct 94 from the multiple air inlets 95 on the outside of the first air duct 94, and some hot air enters the connecting pipe 99 from the exhaust pipe 98, and then enters the second air duct 910. This facilitates the rapid transfer of heat from the hot air to the aluminum-material first air duct 94 and the second air ducts. 910, while the heat dissipation fins 913 on the outer side of the first air duct 94 and the second air duct 910 further absorb heat quickly, and at the same time, the first air duct 94 and the second air duct 910 drive the turning plate 914 on their outer side to rotate, which facilitates the turning of the medicinal materials to be dried placed in the inner cavity of the medicine tank 51 of the medicine loading mechanism 5. The heat absorbed by the heat dissipation fins 913 is also continuously transferred to the medicinal materials in contact with it, which facilitates the heating and drying of the medicinal materials while turning them over, effectively improving the effect of uniformly drying Chinese medicinal materials.

[0033] A drug-carrying mechanism 5 is installed on the upper end of the base plate 3. The drug-carrying mechanism 5 includes a drug-carrying tank 51 located outside three sets of second air ducts 910 and one set of first air ducts 94. An air-blowing component 52 is installed in the middle of the bottom of the inner cavity of the drug-carrying tank 51. The lower end of the air-blowing component 52 is installed on the upper end of the base plate 3. The lower end of the drug-carrying tank 51 is connected to a discharge pipe 53. A valve 54 is installed on the outside of the discharge pipe 53. The air-blowing component 52 includes a support pipe 521 installed in the middle of the bottom of the inner cavity of the drug-carrying tank 51. The first air duct 94 and the second air duct 910 are both inserted into the support pipe 521. L-shaped pipes 522 are connected at equal intervals to the outside of the support pipe 521. Through holes that are inserted into the L-shaped pipes 522 are provided at equal intervals at the bottom of the inner cavity of the drug-carrying tank 51. A protective net 55 is installed in the inner cavity of each through hole.

[0034] By opening the chamber door 2, the experimental Chinese medicinal materials to be dried are placed in multiple medicine-carrying barrels 51. While the drying mechanism 9 heats and stirs the medicinal materials for drying, hot air from the first air duct 94 and the second air duct 910 enters from their lower ends into the support pipe 521 of the air blowing assembly 52, and then into the L-shaped pipe 522. Therefore, the remaining hot air enters the inner cavity of the medicine-carrying barrel 51 through the L-shaped pipe 52 and the through-hole, facilitating the stirring of the medicinal materials located at the bottom of the inner cavity of the medicine-carrying barrel 51, effectively improving the drying efficiency of the medicine-carrying barrel 51. The mixed drying of medicinal materials ensures that some materials cannot be effectively turned over, which would prevent them from being heated and dried evenly and affecting the quality of the subsequent materials. It also makes it easier to utilize the remaining heat in the air, further improving the efficiency of heating and drying. The designed protective net 55 prevents the materials from falling, effectively improving the usage effect. Finally, by opening the valve 54, the dried materials are turned over by the turning plate 914 and scraped from the medicine tank 51 into the discharge pipe 53 for easy collection by the staff.

[0035] An exhaust pipe 12 is installed on the outside of the chamber 1, and an electromagnetic vent valve 13 is installed on the outside of the exhaust pipe 12. The electromagnetic vent valve 13 can be opened intermittently at regular intervals by an external controller to facilitate the removal of water vapor generated in the inner cavity of the chamber 1 after heating and drying. This effectively improves the drying effect and avoids excessive humidity in the inner cavity of the chamber 1, which would reduce the drying effect.

[0036] Working Principle: This utility model is controlled and connected via an external controller, a booster fan 17, an electromagnetic vent valve 13, an external automatic temperature controller, and a temperature sensor designed in the upper middle part of the base plate 3. In use, by opening the chamber door 2, the experimental Chinese medicinal materials to be dried are placed in multiple medicine containers 51. The booster fan 17 is then started, allowing air to enter the inner cavity of the top cover 6 through the air inlet pipe 7. The air is then filtered through coarse and fine filter plates 102 and 103 to remove large and small particles, followed by fine dust particles filtered through a filter cotton plate 104, and finally, activated carbon filter plate 105 for effective purification. This significantly improves the stratified filtration effect of the air. Pulling out the base 101, the coarse filter plate 102, fine filter plate 103, filter cotton plate 104, and activated carbon filter plate 105 are all inserted into the slot 107, facilitating installation, disassembly, and replacement, and making them easy to use. Air then enters the heating chamber 15 through a slot on the outside of a partition 14, where it is heated by the heater 16. The booster fan 17 then draws the heated air into its inner cavity through a pipe, and then discharges it to the impeller cover 91 through a hose 18. The pressurized hot air blows the impeller 93 inside the impeller cover 91, which in turn drives the support shaft 92 and the first air duct 94 at its lower end to rotate. The pulley 911 on the outside of the first air duct 94, via belt 912, synchronously drives three other sets of impellers 911. As the second air duct 910 rotates, some hot air enters the inner cavity of the first air duct 94 from multiple air inlets 95 on the outside of the first air duct 94, while some hot air enters the connecting pipe 99 from the exhaust pipe 98 and then enters the second air duct 910. This facilitates the rapid transfer of heat from the hot air to the aluminum-material-based first and second air ducts 94 and 910. The heat dissipation fins 913 on the outside of the first and second air ducts 94 and 910 further absorb heat rapidly. Simultaneously, the first and second air ducts 94 and 910 drive the outer turning plates 914 to rotate, facilitating the stirring of the herbs to be dried placed in the inner cavity of the medicine container 51 of the medicine-carrying mechanism 5. The heat absorbed by the heat dissipation fins 913 is also continuously transferred to the herbs in contact with them, facilitating the drying of the medicine. While the medicinal materials are being heated and dried, they are also being turned over, which effectively improves the uniformity of drying. Simultaneously, hot air from the first air duct 94 and the second air duct 910 enters the support pipe 521 from their lower ends, then enters the L-shaped pipe 522, and then enters the inner cavity of the medicine-carrying tank 51 through the through-hole in the L-shaped pipe 522. This facilitates the turning over of the medicinal materials located at the bottom of the inner cavity of the medicine-carrying tank 51, effectively improving the mixed drying effect of the medicinal materials in the medicine-carrying tank 51. This prevents some medicinal materials from not being effectively turned over, which would lead to uneven heating and drying and affect the quality of the subsequent medicinal materials. It also facilitates the full utilization of the remaining heat in the air, further improving the efficiency of heating and drying. An external controller intermittently opens the electromagnetic vent valve 13 at regular intervals.This design facilitates the removal of water vapor generated during heating and drying within the chamber 1, effectively improving the drying process and preventing excessive humidity inside the chamber, which would reduce the drying efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
