Description

Technical Field

[0001] The invention belongs to the technical field of hot air drying equipment and relates to hot air circulation drying equipment for Chinese herbal medicine slices. Background Art

[0002] Chinese herbal medicine slices are Chinese herbal medicines that have been processed according to the theory of traditional Chinese medicine and the processing methods of traditional Chinese medicine, and can be directly used in clinical Chinese medicine. This concept shows that there is no absolute boundary between Chinese herbal medicines and Chinese herbal medicine slices. Chinese herbal medicine slices include some slices of Chinese herbal medicines processed at the place of origin, original herbal medicine slices, and sliced ​​and processed herbal medicine slices.

[0003] Traditional methods for drying Chinese herbal medicines include natural drying, shade drying, or using ovens and other equipment. Although the traditional natural drying method is more gentle, it is very time-consuming and only suitable for certain medicinal materials; while modern hot air drying is more efficient than traditional natural drying, the drying method is not gentle enough, and the hot air is continuously blown on the surface of the medicinal materials. The entire drying process is not only energy-intensive, but also causes the loss of the effective ingredients of the medicinal materials. At the same time, the traditional method of continuous air supply and drying on the surface of the medicinal materials cannot fully utilize the large amount of heat energy in the hot air, and it is directly discharged when the temperature is high, and the effect of heat energy recycling cannot be achieved. In addition, the hot air blows from bottom to top, and only one air outlet is set at the bottom. The lower layer is heated at a high temperature, and the temperature gradually decreases to the upper layer, and it will carry water vapor, so the lower layer dries faster than the upper layer, resulting in uneven heating of the upper and lower layers. Therefore, we propose a hot air circulation drying equipment for Chinese herbal medicines to solve the above-mentioned problems. Summary of the invention

[0050] The drying equipment also includes a plurality of groups of holding mechanisms that are detachably positioned and connected to the positioning seats, and are used to hold Chinese herbal medicines. After the holding mechanisms are loaded with Chinese herbal medicines, they are placed in the box 1 layer by layer through the plurality of positioning seats to dry the Chinese herbal medicines. The holding mechanism includes a holding tray 10 that is adapted to be snapped with the rotating ring 5, and a plurality of air holes 101 are evenly distributed on the bottom wall of the holding tray 10. The bottom of the holding tray 10 is annular and equidistantly fixed with a plurality of positioning rods 13 that are plugged and matched with the positioning holes 81. First, the Chinese herbal medicines to be dried are placed into the holding slot on the holding tray 10. The holding tray 10 can be stably placed on the ground or a table top through a plurality of positioning rods 13, and a plurality of air holes 101 are provided on the bottom wall of the holding slot, so that the Chinese herbal medicines will not leak out from the air holes 101. On the one hand, they can be used for the passage of hot air to complete the drying process. On the other hand, when loading the Chinese herbal medicines, the fine powder or dust can be sieved out by shaking the tray 10, and then put into the box 1 for drying; after loading the appropriate amount of Chinese herbal medicines, the entire tray 10 is lifted and moved into the box 1, so that the tray 10 is located directly above the rotating ring 5, and the positioning rod 13 is aligned with the positioning hole 81, and the tray 10 is clamped in the rotating ring 5 through the positioning hole 81 by the positioning rod 13, and the tray 10 is supported and positioned by the supporting positioning ring 8, otherwise, the tray 10 can be quickly taken out by lifting it up. The outer wall of the tray 10 is fixedly connected with an annular handle 12, which is convenient for lifting and moving the tray 10.

[0051] The drying device also includes a hot air conveying mechanism disposed on the top of the box 1, which is connected to multiple groups of positioning seats through pipelines at the same time, and is used for conveying hot air. The hot air conveying mechanism includes a hot air blower 2 fixedly connected to the outer wall of the top of the box 1, the air inlet end of the hot air blower 2 is fixedly connected to the air inlet pipe 11, the air outlet end of the hot air blower 2 is fixedly connected to the air outlet pipe 6, the other end of the air outlet pipe 6 is sealed and penetrates the top of the box 1 and is fixedly connected to the bottom inner wall of the box 1, and an exhaust pipe 38 is provided on the top of the box 1 for discharging humid hot air; turn on the hot air blower 2, so that the outside air enters the hot air blower 2 from the air inlet pipe 11, and heats the air at the same time, and the heated hot air is blown out from the air outlet pipe 6 to convey the hot air. A hot air delivery pipe 9 is fixedly penetrated inside the partition 3, one end of the hot air delivery pipe 9 is fixedly connected to one side of the air outlet pipe 6, and the other end of the hot air delivery pipe 9 passes through the top of the partition 3 and extends upward to the inner side of the rotating ring 5, and is located at the center of the rotating ring 5; the hot air blown out from the hot air blower 2 can enter the hot air delivery pipe 9 along the air outlet pipe 6, and deliver the hot air to the inner space of the rotating ring 5. The hot air delivery pipe 9 is located on the outer wall of the inner side of the rotating ring 5, and is fixedly connected with multiple air supply pipes 25 in an annular shape and equidistantly penetrated, and multiple air outlet heads 26 are arranged side by side and equidistantly on the top of the outer wall of the multiple air supply pipes 25. The hot air is simultaneously transported from the hot air delivery pipe 9 to multiple air supply pipes 25, and finally blown upward from multiple air outlets 26; since the holding tray 10 is positioned and clamped on the rotating ring 5, and the air supply pipe 25 is located below the holding tray 10 and located in the inner space of the rotating ring 5, the hot air blown upward from the air outlet 26 can be directly blown onto the Chinese medicinal pieces in the holding tray 10 through the air vents 101, thereby achieving a drying effect on the Chinese medicinal pieces. In the process of drying the Chinese medicinal pieces with hot air, a certain amount of moisture will be contained in the hot air, and the humid hot air will finally be discharged from the exhaust pipe 38 outside the box 1.

[0052] The present invention can be used in the field of hot air circulation drying equipment for Chinese herbal medicine slices, and can also be applied to other fields of the present invention.

[0053] Embodiment 2, this embodiment is a further improvement of the previous embodiment: Figure 1-Figure 10As shown, the drying device also includes a driving mechanism arranged at the top of the box 1, which is used to simultaneously drive multiple groups of positioning seats to rotate, and when the positioning seats rotate, the containing mechanism can be driven to rotate at the same time to achieve a uniform drying effect; during the rotation of the containing mechanism, the hot air can be intermittently blown on the Chinese herbal medicine slices, and part of the hot air can be circulated back to the hot air conveying mechanism, which can achieve energy saving effect while also being able to dry the Chinese herbal medicine slices in a gentle drying manner, effectively retaining the active ingredients in the tablets. The driving mechanism includes a driving motor 35 fixedly connected to the outer wall of the top of the box 1, and the top of the partition 3 located at the bottom is rotatably connected to a rotating rod 27, and the top of the rotating rod 27 rotates in turn to penetrate the tops of the other partitions 3 and is rotatably connected to the top inner wall of the box 1, and the output shaft of the driving motor 35 rotates to penetrate the top of the box 1 and is fixedly connected to the top of the rotating rod 27. The outer wall fixed sleeve of the rotating rod 27 is provided with a plurality of gears 30, and the outer wall fixed sleeve of the rotating ring 5 is provided with an outer gear ring 7 meshing with the corresponding gears 30. Start the driving motor 35 to drive the rotating rod 27 to rotate, and the meshing movement of the gear 30 and the outer gear ring 7 can drive multiple rotating rings 5 ​​to rotate simultaneously, and then the placing plate 10 can be positioned and clamped in the rotating ring 5 to drive the placing plate 10 to rotate synchronously; because the hot air delivery pipe 9 and the multiple air supply pipes 25 are in a static air supply state, the continuous rotation of the Chinese herbal medicines can improve the uniformity of the drying of the Chinese herbal medicines, so that all the Chinese herbal medicines can be exposed to the hot air drying.

[0054] Embodiment 3, this embodiment is a further improvement of the previous embodiment: Figure 1-Figure 10 As shown, a fixing ring 17 is fixedly connected to the top of the partition 3, and the outer wall of the fixing ring 17 is rotatably fitted with the inner wall of the rotating ring 5. The top of the fixing ring 17 is annularly equidistantly fixed with a plurality of protrusions 18 that intermittently interfere with the positioning rod 13, and the tops of the plurality of protrusions 18 are all provided with a second inclined surface 181. The inclination direction of the second inclined surface 181 is set from low to high in the rotation direction of the rotating ring 5. In the process of the rotating ring 5 driving the holding tray 10 to rotate, the positioning rod 13 rotates and moves with the holding tray 10 at the same time. When the bottom end of the positioning rod 13 is in contact with the second inclined surface 181, the holding tray 10 can be driven to move upwards for a distance in the rotating ring 5 by the plurality of positioning rods 13. When the positioning rod 13 is out of interference with the entire protrusion 18, it quickly moves downward and resets under the gravity of the holding tray 10 itself, thereby achieving a vibration effect on the internal Chinese herbal medicine pieces; through this setting, in the process of the holding tray 10 driving the Chinese herbal medicine pieces to rotate and dry, the vibration can further improve the overall drying effect.

[0055] Embodiment 4, this embodiment is a further improvement of the previous embodiment: Figure 1-Figure 11As shown, a butt joint 19 is rotatably connected to the bottom inner wall of the holding tray 10, and the butt joint 19 is a structure with a closed top and an open bottom. Its top extends upward into the holding tray 10, and its bottom extends downward and is positioned and plugged with the top of the hot air delivery pipe 9. The butt joint 19 is located on the outer wall of the holding tray 10 and is equidistantly and fixedly connected with a plurality of heat-conducting air delivery pipes 21 in a circular shape. A hot air circulation delivery component connected to the heat-conducting air delivery pipes 21 is provided in the box body 1, and the hot air circulation delivery component is connected to the air inlet pipe 11 for circulating and delivering hot air. A wind control component is provided in the hot air delivery pipe 9 for changing the delivery path of the hot air so that the hot air is intermittently delivered back and forth between the heat-conducting air delivery pipe 21 and the air supply pipe 25. When the holding tray 10 is positioned and placed on the rotating ring 5, as shown in FIG. Fig.11 As shown, the butt joint 19 can be positioned and plugged into the top end port of the hot air delivery pipe 9. Since the hot air delivery pipe 9 is in a stationary air supply state, the air supply pipe 25 and the heat-conducting air delivery pipe 21 are both in a stationary state; when the wind control component is controlled to connect the hot air delivery pipe 9 with the air supply pipe 25, the butt joint 19 is in a closed state, and the hot air flows through the air supply pipe 25 and is blown out from the air outlet 26, thereby achieving the effect of blowing and drying the Chinese herbal medicine slices; when the wind control component is controlled to connect the hot air delivery pipe 9 with the butt joint 19, the air supply pipe 25 is in a closed state, and the hot air flows through the butt joint 19 from the heat-conducting air delivery pipe 21. The hot air is transported in the air duct 21. At this time, the hot air is no longer blown directly on the Chinese herbal medicine slices, but the temperature of the hot air is transferred to the Chinese herbal medicine slices through the heat-conducting air duct 21 for heating and drying, thereby achieving a gentle heating effect; in addition, since the hot air does not touch the Chinese herbal medicine slices and does not flow directly in the box 1, the hot air flowing from the heat-conducting air duct 21 does not carry moisture, and then flows back to the hot air blower 2 from the hot air circulation conveying component, and is sent into the box 1 again for drying and utilization, which not only reduces the emission of moist hot air, but also reduces the energy consumption generated by the hot air blower 2. In addition, since the heat-conducting air duct 21 is in a stationary state, and the placing tray 10 rotates and moves with the Chinese herbal medicine slices, the heat-conducting air duct 21 can also achieve the effect of stirring the Chinese herbal medicine slices, and combined with the intermittent vibration of the placing tray 10, the turning effect of the Chinese herbal medicine slices can be further improved, thereby improving the uniformity and efficiency of drying. Of course, in order to effectively achieve the flipping effect, or to make the flipping effect better, heat-conducting fins can be set on the outer wall of the heat-conducting air duct 21. The heat-conducting fins can be sheet-shaped or protruding. The specific shape is not limited here, as long as it can meet the requirements of increasing the thermal conductivity effect on the one hand and being able to flip the Chinese herbal medicine pieces more effectively on the other hand.

[0056] In one aspect of the present embodiment, a first docking ring 22 is fixedly sleeved on the outer wall of the docking pipe 19 located below the holding tray 10, and a plurality of docking rods 23 are fixedly connected to the bottom of the first docking ring 22 in an annular shape and equidistantly, and a second docking ring 16 is fixedly sleeved on the outer wall of one end of the hot air delivery pipe 9 located inside the rotating ring 5, and a plurality of docking holes 161 correspondingly plugged and matched with the docking rods 23 are opened in an annular shape and equidistantly on the top of the second docking ring 16. In the process of placing the holding tray 10, the bottom end of the docking pipe 19 will be directly inserted into the top of the hot air delivery pipe 9, and the docking rods 23 will be correspondingly plugged into the docking holes 161, and finally the bottom of the first docking ring 22 will just fit on the top of the second docking ring 16, thereby achieving the positioning and plugging effect of the docking pipe 19, so that the holding tray 10 will not drive the heat-conducting air delivery pipe 21 to rotate during the rotation of the Chinese herbal medicine pieces, thereby achieving the effect of moving the Chinese herbal medicine pieces.

[0057] Embodiment 5, this embodiment is a further improvement of the previous embodiment: Figure 1-Figure 11As shown, the hot air circulation conveying assembly includes a hot air circulation return pipe 24 fixedly connected to the top of the lowest partition 3, the top of the hot air circulation return pipe 24 is fixedly passed through the tops of the remaining partitions 3 and the top of the box body 1 in sequence and is fixedly connected with an air box 36, the air box 36 is fixedly installed on the top outer wall of the box body 1, and one end of the air inlet pipe 11 is fixedly connected to one side of the air box 36, and the side of the air box 36 away from the air inlet pipe 11 is fixedly connected to an air inlet pipe 37, the inner wall of the holding plate 10 is rotatably fitted with an air guide ring 15, the interior of the air guide ring 15 is provided with an air guide cavity 151, and the ends of multiple heat-conducting air delivery pipes 21 away from the docking pipe 19 are all connected with the air guide cavity 151, a first U-shaped air guide pipe 20 connected with the air guide cavity 151 is fixedly provided on one side of the top of the air guide ring 15, and the outer wall of the hot air circulation return pipe 24 is provided with multiple L-shaped pipe heads 29 corresponding to the first U-shaped air guide pipe 20 for plugging and matching. First, when positioning the holding tray 10 and clamping it on the rotating ring 5, first support the positioning rod 13 and place it on the supporting positioning ring 8, then use your hand to move the first U-shaped air duct 20 or the heat-conducting air duct 21 to drive the air guide ring 15 to rotate as a whole, so that the first U-shaped air duct 20 is aligned with the L-shaped tube head 29; at this time, one hand holds the corresponding position of the first U-shaped air duct 20 and the L-shaped tube head 29, and the other hand drives the holding tray 10 to rotate through the annular handle 12, thereby driving the positioning rod 13 to rotate and move, and when the positioning rod 13 corresponds to the positioning hole 81, the entire holding tray 10 will fall directly downward and be positioned and clamped in the rotating ring 5. At the same time, one end of the first U-shaped air duct 20 is also directly moved downward and inserted into the corresponding L-shaped tube head 29, thereby completing the positioning and placement of the holding tray 10. Since the first U-shaped air duct 20 corresponds to the L-shaped pipe head 29 in the design, the docking rod 23 also corresponds to the docking hole 161. Therefore, when the placing tray 10 falls, the docking rod 23 will be directly inserted into the docking hole 161 to complete the positioning and insertion between the docking pipe 19 and the hot air delivery pipe 9. After the hot air completes heat exchange and drying in the heat-conducting air delivery pipe 21, the hot air still has a relatively high temperature. At this time, the hot air enters the air guide cavity 151 from the heat-conducting air delivery pipe 21, and is then transported from the first U-shaped air duct 20 and the docking L-shaped pipe head 29 to the hot air circulation return pipe 24, and finally enters the air box 36. Since the hot air blower 2 is in a continuous air supply, the refluxed hot air can be directly sent back into the hot air blower 2. Since the hot air at this time has a certain temperature, it does not require additional large power consumption to heat it, so it can play an effect of reducing energy consumption. When the hot air flows through the air supply pipe 25 and is blown out from the air outlet 26, the air required by the hot air blower 2 is directly sucked into the air box 36 from the air intake pipe 37 and then sent to the hot air blower 2 for heating.In order to further reduce energy consumption and make full use of the heat energy stored in the moist hot air, the exhaust pipe 38 can be extended into the air box 36 to preheat the inhaled air. This technology belongs to the existing conventional technology in this field, so it will not be described in detail in this application. In addition, in order to ensure the tightness of the hot air flow, the use of sealing rings to connect the pipes is also a conventional technology.

[0058] Embodiment 6, this embodiment is a further improvement of the previous embodiment: Figure 1-Figure 12As shown, the wind control component includes an inner tube 31 which is sealingly and slidably connected to the hot air delivery pipe 9 located on one side of the inner space of the rotating ring 5. The inner tube 31 is a structure with a closed top and an open bottom. The outer wall of the inner tube 31 is annular and equidistantly provided with a plurality of air outlet holes 311 intermittently connected to the air supply pipe 25. The outer wall of the hot air delivery pipe 9 is annular and equidistantly fixedly connected with a plurality of second U-shaped air guide pipes 28. The plurality of second U-shaped air guide pipes 28 are respectively located directly above the corresponding plurality of air supply pipes 25, and both ends of the second U-shaped air guide pipes 28 are connected to the hot air delivery pipe 9. The bottom end port of the second U-shaped air guide pipe 28 is intermittently connected with the air outlet hole 311, and the top end port of the second U-shaped air guide pipe 28 is located above the top of the inner tube 31, and is also located at the butt joint 19. Below the bottom end, the top of the partition 3 is located on one side of the inner space of the rotating ring 5 and is fixedly connected to an L-shaped plate 33, and the top of the L-shaped plate 33 is slidably penetrated by an L-shaped rod 32, one end of the L-shaped rod 32 penetrates one side of the hot air delivery pipe 9 and is fixedly connected to the outer wall of one side of the inner tube 31, the outer wall of the L-shaped rod 32 is sleeved with a return spring 34, and the top of the return spring 34 is fixedly connected to the bottom of the L-shaped plate 33, the bottom end of the return spring 34 is fixedly connected to the outer wall of the L-shaped rod 32, and one side of the outer wall of the hot air delivery pipe 9 is provided with a strip hole 91 used in conjunction with the L-shaped rod 32, and the bottom of the placing tray 10 is fixedly connected to an arcuate strip plate 14 that intermittently contacts the top of the L-shaped rod 32, and the bottom sides of the arcuate strip plate 14 are provided with first inclined surfaces 141. When the receiving tray 10 rotates, the arc-shaped strip 14 is driven to rotate. When the first inclined surface 141 of the arc-shaped strip 14 contacts with the top end of the L-shaped rod 32, the L-shaped rod 32 is pushed to move downward and the reset spring 34 is stretched. At the same time, the L-shaped rod 32 drives the inner tube 31 to move downward. When the arc-shaped strip 14 is out of contact with the L-shaped rod 32, the elastic force of the reset spring 34 drives the L-shaped rod 32 to reset upward, thereby driving the inner tube 31 to move upward, so that the inner tube 31 can move back and forth up and down with the rotation of the receiving tray 10. By controlling the rotation of the driving motor 35 and the differential rotation of the gear 30 and the outer gear ring 7, the rotation speed of the tray 10 can be set relatively slowly, so that the interval time of the inner tube 31 moving up and down is relatively long; in addition, the arc strip 14 can also be set to a half-circle form, that is, when the tray 10 rotates half a circle, the inner tube 31 starts to move up or down and quickly remains stationary. This effect can be set according to the specific situation, and the length of the inner tube 31 staying up and down can be set according to the length of the arc strip 14. Fig.11As shown, at this time, the inner tube 31 is in an upward staying state, the inner tube 31 is connected to the bottom end port of the second U-shaped air duct 28, and the air supply duct 25 is closed. At this time, the hot air is transported from the inner tube 31 to the docking tube 19 through the second U-shaped air duct 28; when the inner tube 31 moves downward and is in a staying state, the inner tube 31 blocks the bottom end port of the second U-shaped air duct 28 and is connected to the air supply duct 25. At this time, the hot air is transported from the inner tube 31 to the air supply duct 25 through the air outlet 311, thereby realizing the switching control effect of the hot air passage, thereby achieving a mild drying effect and a recycling of hot air, which not only reduces energy consumption, makes the drying efficiency higher, and the drying uniformity better, but also can effectively retain the effective ingredients of the medicinal materials.

[0059] However, as is well known to those skilled in the art, the working principles and wiring methods of the hot air blower 2 and the drive motor 35 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
