Description

Technical Field

[0001] The invention relates to the field of drying, and in particular to a high-efficiency drying device and process for processing traditional Chinese medicinal materials. Background Art

[0002] Traditional Chinese medicine has its roots in China, and Chinese medicinal materials are often used in traditional Chinese medicine. The storage of Chinese medicinal materials generally requires multiple processes such as collection, cleaning, and drying. Among them, Chinese medicinal materials cannot be dried at too high a temperature when drying, which will cause the loss of medicinal efficacy of Chinese medicinal materials. Similarly, Chinese medicinal materials cannot be over-dried, which will reduce the quality of Chinese medicinal materials. Low-temperature drying will result in a relatively long drying process, and it is easy to burn Chinese medicinal materials by manual drying.

[0003] When drying medicinal materials, they are generally dried through an air inlet in the box. Since the air intake is relatively concentrated, the closer the Chinese medicinal materials are to the air inlet, the faster they dry. Therefore, it is necessary to adjust the distance between the Chinese medicinal materials and the air inlet to adjust the uniformity of drying. However, after the Chinese medicinal materials that are close to drying are changed, the humidity will rise again due to the absorption of hot and humid air, and multiple repetitions are required, which not only reduces the drying efficiency, but also reduces the quality of the Chinese medicinal materials due to multiple humidification and drying that takes away more effective ingredients. Summary of the invention

[0004] In view of the above, the technical problem that this application intends to solve is how to improve the drying efficiency of Chinese medicinal materials while keeping the position of the Chinese medicinal materials unchanged, and how to avoid over-drying of the Chinese medicinal materials;

[0005] On the one hand, the object of the present invention is to provide a high-efficiency drying device for processing Chinese medicinal materials, comprising:

[0006] The box body has a sealed door at the front, and the inside of the box body is divided into multiple layer structures by a layered structure, wherein an air inlet switch connected to the air inlet pipe and an air outlet structure connected to the air outlet pipe are provided in the layer structure, and the opening and closing states of the air inlet switch and the air outlet structure in the same layer structure are configured to be opposite to each other;

[0007] The layered structure includes a column, a plurality of support platforms are arranged at intervals on the column, a drying tray is fixedly connected to the support platform through an elastic member, a first air flow distribution plate is fixedly connected to the lower part of the drying tray, a second air flow distribution plate fixed to the box body is arranged between the drying tray and the first air flow distribution plate, and the first air flow distribution plate and the second air flow distribution plate form an integral sealing plate when they are attached to each other;

[0008] The air intake duct includes a hot air intake pipe at the upper end and a block inside which is driven by a driving device to be raised and lowered. When the integral sealing plate is formed, the block will automatically drop to the bottom of the next air intake switch;

[0009] The air outlet duct discharges the hot and humid air from each layer of the structure through the air outlet structure.

[0010] Optionally, the air outlet structure includes an enclosure structure arranged around the air outlet, a closed door is rotatably connected inside the enclosure structure, the enclosure structure is provided with an extending folding plate in the rotation direction of the closed door, the air outlet is connected to the air outlet pipe, a hygroscopic ball that can be reciprocated into the air outlet is fixed inside the air outlet pipe, and an extrusion piece for squeezing the hygroscopic ball is also provided inside the air outlet pipe, and when the closed door contacts the folding plate, the hygroscopic ball retracts and then extends out again.

[0011] Optionally, the first airflow distribution plate and the second airflow distribution plate are both provided with multiple airflow holes, and the first airflow distribution plate is also provided with a blocking column. The airflow holes on the first airflow distribution plate are completely staggered with the airflow holes on the second airflow distribution plate, and the blocking columns correspond one-to-one with the airflow holes on the second airflow distribution plate.

[0012] Optionally, a plurality of first contact switches and second contact switches that can move up and down are installed on the column, the first contact switch is electrically connected to the driving device, and the second contact switch is electrically connected to the air intake switch of the same layer structure.

[0013] Optionally, the desiccant ball is fixedly connected to the end of the output shaft of the cylinder, a sealing plate is fixed on the output shaft of the cylinder, the sealing plate is adapted to the air outlet, a V-shaped connecting rod is provided at the upper and lower parts of the output shaft of the cylinder, one end of the connecting rod is connected to the sealing plate by a pull rope, the middle part of the connecting rod is rotatably connected to the air outlet pipe by a rotating pin, and the other end of the connecting rod is connected to an extrusion plate.

[0014] Optionally, a third contact switch is installed at the lower part of the folding plate, and the third contact switch is electrically connected to the cylinder.

[0015] Optionally, a fourth contact switch is installed at the air inlet switch, and when the air inlet switch is turned on, the fourth contact switch causes the air outlet structure in the same layer structure to be in a closed state.

[0016] On the other hand, the present application also provides a process for efficiently drying Chinese medicinal materials, which uses the efficient drying device for processing Chinese medicinal materials as described above.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. When the Chinese medicinal materials in the drying tray are reduced in weight by drying, they will rise. When the Chinese medicinal materials are dried to a predetermined degree of dryness, the drying tray will trigger the first contact switch and the second contact switch. A delay switch is also connected between the first contact switch and the motor, and the time of the delay closing can be set to control the number of revolutions of the motor output shaft. The rotation of the motor output shaft can drive the wire-releasing roller to rotate. After the wire-releasing roller releases the wire, the block at the other end moves downward along the air intake duct under the action of its own weight, thereby ensuring that the block can smoothly fall to the bottom of the air intake switch of the next layer structure, and can realize the diversion of hot air, so that the hot air no longer passes through the layer structure that has been dried, so that the Chinese medicinal materials that have been dried will not be repeatedly heated and dried, thereby avoiding over-drying of the Chinese medicinal materials, and also avoiding moisture from wetting the important materials that have been dried again, thereby avoiding the Chinese medicinal materials from going back and forth between drying and wetting, thereby ensuring the quality of the Chinese medicinal materials;

[0019] 2. When the first airflow distribution plate and the second airflow distribution plate are attached together, an integral sealing plate is formed. After the integral sealing plate is formed, it can play a heat conduction role, and the residual heat of the next layer structure can be utilized to dry the upper layer structure through the residual heat;

[0020] 3. When the third switch is triggered, the output shaft of the first cylinder will be retracted and then extended. When the output shaft of the first cylinder is retracted, the sealing plate contacts the connecting rod, causing the connecting rod to rotate around the pin shaft. At the same time, the hygroscopic ball can be retracted from the air outlet into the air outlet pipe, and the extrusion plate squeezes the hygroscopic ball, thereby squeezing the moisture in the hygroscopic ball and shrinking the hygroscopic ball. Subsequently, the output shaft of the first cylinder is extended, and the hygroscopic ball returns to the enclosure structure. As the hygroscopic ball shrinks, a gap is left between the closed door and the folding plate again, and when the sealing plate is extended, the connecting rod will be driven to rotate through the pull rope, so that the extrusion plate opens and the hygroscopic ball can smoothly enter the enclosure structure, thereby automatically completing the collection of moisture in the hygroscopic ball.

[0031] like Figure 1As shown, a high-efficiency drying device for processing Chinese medicinal materials includes a box body, a sealed door 7 that can be opened and closed is provided at the front of the box body, a wire-releasing roller 3 is installed on the top of the box body, the wire-releasing roller 3 is fixedly connected to the output shaft of the motor 4 through a braking device, the start switch of the motor 4 is electrically connected to the first contact switch, the other end of the wire of the wire-releasing roller 3 is fixedly connected to a block 8 in an air intake pipe 6, the air intake pipe 6 is connected to a plurality of air intake switches 9, and the air intake switches 9 are evenly installed on the inner side wall of the box body;

[0032] The motor 4 has a delayed shut-off function, or a delayed switch is connected so that the motor 4 can automatically shut down after a certain number of revolutions after starting;

[0033] like Figure 5 As shown, a column 14 is fixed at the center of the box, and a plurality of support platforms 13 are evenly spaced on the column 14. An elastic member is fixed on the support platform 13, and a drying tray 10 is fixed on the top of the elastic member. A first air flow distribution plate 12 is fixedly connected to the lower part of the drying tray 10, and a gap is left between the drying tray 10 and the first air flow distribution plate 12. A second air flow distribution plate 11 is arranged in the gap, and the second air flow distribution plate 11 is fixedly connected to the peripheral wall of the box. The first air flow distribution plate 12 and the second air flow distribution plate 11 are both provided with a plurality of air flow passages. Hole 21, a blocking column is also provided on the first air flow distribution plate 12, the air flow through hole 21 on the first air flow distribution plate 12 is completely staggered with the air flow through hole 21 on the second air flow distribution plate 11, and the blocking column corresponds to the air flow through hole 21 on the second air flow distribution plate 11 one by one, so when the first air flow distribution plate 12 and the second air flow distribution plate 11 are attached, an integral sealing plate 26 is formed, and after the integral sealing plate 26 is formed, it can play a heat conduction role, and the waste heat of the next layer structure can be utilized, and the waste heat is used to dry the upper layer structure;

[0034] The column 14 is also provided with a first contact switch and a second contact switch with adjustable heights. The first contact switch is electrically connected to the motor 4, and the second contact switch is electrically connected to the air intake switch 9 of the same layer structure.

[0035] Therefore, when the Chinese medicinal materials in the drying tray 10 are reduced in weight through drying, they will rise. When the Chinese medicinal materials are dried to a predetermined degree of dryness, the drying tray 10 will trigger the first contact switch and the second contact switch, and a delay switch is also connected between the first contact switch and the motor 4, and the time of the delayed closing can be set to control the number of revolutions of the output shaft of the motor 4. The rotation of the output shaft of the motor 4 can drive the wire-releasing roller 3 to rotate. After the wire-releasing roller 3 releases the wire, the block 8 at the other end moves downward along the air intake duct 6 under the action of its own weight, thereby ensuring that the block 8 can smoothly fall to the bottom of the air intake switch 9 of the next layer structure, and can realize the diversion of hot air, so that the hot air no longer passes through the layer structure that has been dried, so that the Chinese medicinal materials that have been dried will not be repeatedly heated and dried, thereby avoiding over-drying of the Chinese medicinal materials, and also avoiding moisture from wetting the important materials that have been dried again, thereby avoiding the Chinese medicinal materials from going back and forth between drying and wetting, thereby ensuring the quality of the Chinese medicinal materials;

[0036] like Figure 2-4 As shown, when the second contact switch is triggered, the air inlet switch 9 of the current layer structure will be closed, and the opening and closing states of the air inlet switch 9 and the air outlet structure in the same layer structure are always opposite. A fourth contact switch is provided at the air inlet switch 9, and the fourth contact switch will be triggered when the air inlet switch 9 is closed;

[0037] An air outlet 25 is provided on the other side of the box body, and the air outlet 25 is provided with an enclosure structure 16. A top plate 19 is provided on the top of the enclosure structure 16, and one end of the top plate 19 is fixedly connected to the output shaft of the second cylinder 18. The second cylinder 18 is electrically connected to the fourth proximity switch. A closed door 22 is rotatably connected in the enclosure structure 16, and the enclosure structure 16 is provided with an extended folding plate 20 in the rotation direction of the closed door 22. The air outlet 25 is communicated with the air outlet pipe 2, and the first cylinder 1 is fixed in the air outlet pipe 2. The output shaft of the first cylinder 1 is connected to a moisture-absorbing ball 23, and an extrusion piece for squeezing the moisture-absorbing ball 23 is also provided in the air outlet pipe 2. The extrusion piece includes a V-shaped connecting rod 17 at the upper and lower parts of the output shaft of the first cylinder 1, and one end of the connecting rod 17 is connected to the sealing plate 26 on the output shaft of the first cylinder 1 by a pull rope, and the middle part of the connecting rod 17 is rotatably connected to the air outlet pipe 2 by a pin shaft. The other end of the rod 17 is connected to a squeezing plate 24, and a third contact switch is installed at the lower part of the folding plate 20. The third contact switch is electrically connected to the cylinder. When the closed door 22 contacts the folding plate 20, it will contact the third contact switch at the lower part of the folding plate 20. After the third switch is triggered, the output shaft of the first cylinder 1 will be activated to retract and then extend. When the output shaft of the first cylinder 1 retracts, the sealing plate 26 contacts the connecting rod 17, so that the connecting rod 17 rotates around the pin shaft. At the same time, the hygroscopic ball 23 can be retracted from the air outlet 25 into the air outlet pipe 2. The squeezing plate 24 squeezes the hygroscopic ball 23, so that the moisture in the hygroscopic ball 23 can be squeezed out, so that the hygroscopic ball 23 shrinks. Subsequently, the output shaft of the first cylinder 1 extends, and the hygroscopic ball 23 returns to the enclosure structure 16. The hygroscopic ball 23 is a spherical structure that can expand after absorbing moisture and shrink after squeezing out moisture.

[0038] Since the moisture-absorbing ball 23 shrinks the gap between the closed door 22 and the folding plate 20, and the closing plate 26 is extended, the connecting rod 17 is driven to rotate through the pull rope, so that the squeezing plate 24 is opened and the moisture-absorbing ball 23 can smoothly enter the enclosure structure 16, so that the moisture in the moisture-absorbing ball 23 can be automatically collected;

[0039] An exhaust pipe 15 is provided at the bottom of the box body. The exhaust pipe 15 passes through the box body and is connected to the air outlet pipe 2 through a support rod. An exhaust fan is provided at the end of the exhaust pipe 15. The exhaust fan guides the hot and humid air at the bottom to be discharged from the exhaust pipe 15. At the same time, the air outlet pipe 2 can be evacuated to prevent the hot and humid air from flowing into the layer structure from the air outlet pipe 2.

[0040] A total contact switch is also provided on the column 14 of the bottom layer structure. When the Chinese medicinal materials in the drying tray 10 in the bottom layer structure are dried, the total contact switch will be triggered. When the total contact switch is triggered, the hot air inlet pipe and the air outlet 25 will be closed, making the box body a sealed whole.

[0041] The working principle of this application is:

[0042] First, the Chinese medicinal materials to be dried are sampled, the samples are weighed, and then the samples are dried. After the drying of the samples is completed, the dried samples are weighed, so as to obtain the water content that needs to be removed from one unit of Chinese medicinal materials;

[0043] Then the Chinese medicinal materials are evenly piled according to their weight, and a pile of Chinese medicinal materials is evenly placed on a drying tray 10. After all the drying trays 10 in the box are filled and evenly placed, the weight of the Chinese medicinal materials on a single drying tray 10 after drying is calculated, and the distance that the materials on the drying tray 10 will rise after drying is calculated by the weight difference before and after, and the first contact switch and the second contact switch are adjusted to the corresponding positions;

[0044] Then close the box door, and slowly inject hot air into the air intake duct 6 through the hot air intake pipe 5. The block 8 in the air intake duct 6 is initially below the air intake switch 9 of the uppermost layer structure. Since the second contact switch is in a normally open state when it is not triggered, all the air intake switches 9 in the box are in an open state at this time. When the air intake switch 9 is in an open state, the fourth contact switch is triggered, and the fourth contact switch activates the cylinder at the air outlet structure, so that the top plate 19 on the upper part of the air outlet structure is closed.

[0045] Since the blocking block 8 is located below the air inlet switch 9 of the first layer structure, the hot air can only enter the first layer structure through the air inlet switch 9 of the first layer structure after entering the air inlet duct 6. Since the drying tray 10 is pressed by the weight of the Chinese medicinal materials, the spring on the support platform 13 is in an extremely compressed state, and the first air flow distribution plate 12 and the second air flow distribution plate 11 are in a separated state, and the hot air can enter the next layer structure through the distribution effect of the first air flow distribution plate 12 and the second air flow distribution plate 11;

[0046] As the Chinese medicinal materials in the first layer of structure are thoroughly dried, the weight on the drying tray 10 is reduced, so the drying tray 10 moves upward under the elastic force of the elastic member. During the upward movement, the first contact switch and the second contact switch will be triggered. After the first contact switch is closed, the motor 4 will be started, and the motor 4 will drive the wire-releasing roller 3 to rotate a certain number of circles. The wire-releasing roller 3 completes the wire-releasing, and the blocking block 8 moves downward under the action of its own weight and gas pressure until it is located below the air inlet switch 9 of the next layer of structure. The second contact switch closes the air inlet switch 9 of the first layer of structure, and the closing of the air inlet switch 9 of the first layer of structure will close the fourth contact switch. The closing of the fourth contact switch will cause the top plate 19 on the top of the air outlet structure to move away, so that the air outlet structure of the first layer of structure can exhaust air, and the first air flow distribution plate 12 and the second air flow distribution plate 11 of the first layer of structure will form an overall sealing plate 26 when they are fitted together;

[0047] At this time, the hot air enters the air inlet duct 6 and directly enters the second layer structure. Since the hot air is introduced into the second layer structure, the residual heat is transferred to the drying tray 10 of the first layer structure through the integral sealing plate 26, and the material in the first layer structure is further dried by the residual heat.

[0048] During the residual heat drying process, the moisture absorbing ball 23 expands after absorbing the hot and humid air, thereby driving the upper closed door 22 to rotate. The closed door 22 is pressed against the third contact switch on the folding plate 20 to drive the cylinder to retract and extend once. When the cylinder retracts, the sealing plate 26 retracts accordingly, and the sealing plate 26 contacts the connecting rod 17, driving the connecting rod 17 to rotate around the pin shaft. When the cylinder output shaft retracts, the moisture absorbing ball 23 retracts from the air outlet 25 into the air outlet pipe 2. The rotation of the connecting rod 17 drives the squeezing plate 24 to squeeze the moisture absorbing ball 23, so that the moisture of the moisture absorbing ball 23 is squeezed and discharged in the air outlet pipe 2. When the output shaft of the cylinder is extended, the sealing plate 26 drives the connecting rod 17 to return to its position through the pull rope. At the same time, the moisture absorbing ball 23 returns to the enclosure structure 16 through the air outlet 25, and the re-shrunk moisture absorbing ball 23 leaves an air intake gap between the closed door 22 and the folding plate 20.

[0049] It circulates in sequence until the hot air flows only in the bottom layer structure, and finally the Chinese medicinal materials in the bottom layer structure are dried. A total contact switch is also provided on the column 14 of the bottom layer structure. When the Chinese medicinal materials in the drying tray 10 in the bottom layer structure are dried, the total contact switch will be triggered. When the total contact switch is triggered, the hot air inlet pipe and the air outlet 25 will be closed, so that the box body becomes a sealed whole.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
