Description
Technical Field
[0001] The invention belongs to the technical field of medicinal material drying, in particular to a Mongolian medicinal material turning drying device. Background Art
[0002] Mongolian medicine materials refer to Mongolian medicine raw materials that are of natural origin and have not been processed or have only been simply processed. These medicines are usually divided into three categories: plant medicines, animal medicines, and mineral medicines, and are often classified according to the medicinal parts, such as roots and rhizomes, whole herbs, leaves, flowers, fruits and seeds, etc. However, most of these medicines need to be dried during the processing process to facilitate long-term preservation. In the traditional drying method, Mongolian medicine materials are usually placed on a drying tray or in a drying room, and the moisture in the medicine is removed by heating and ventilation.
[0003] In the existing drying devices, in addition to the drying tray type drying devices, there are also drum type drying devices. The drying tray type drying devices require a large amount of usable area, and the amount of medicine dried each time is small. Although the drum type drying device can dry a large amount of medicinal materials at one time, the medicinal materials will pile up together during the rolling drying process, and the overall drying effect is poor and the drying time is long. In the drying of Mongolian medicinal materials, since most of them are plant medicines, the plant medicines are prone to flip and entanglement during the drum drying process, affecting the drying effect. For this reason, technical personnel in this field have proposed a Mongolian medicinal material flip drying device. Summary of the invention
[0004] In order to solve the above technical problems, the present invention provides a Mongolian medicine material tumbling and drying device to solve the problems in the prior art that plant-based medicines are easily entangled and piled up during the tumbling drying process, resulting in poor drying effect, long drying time, and drying that does not meet standards.
[0005] To achieve the above object, the present invention provides the following technical solutions:
[0006] The cam is connected to the second end of the second support frame by the second cam, and the cam is connected to the second support frame by the second cam.
[0007] Preferably, the high temperature resistant expansion bladders are unevenly distributed on the inner wall of the inner air inlet cabin, some of the high temperature resistant expansion bladders are cone-shaped after expansion, and the other part of the high temperature resistant expansion bladders are inclined square after expansion.
[0008] Preferably, the inflation component includes a rotary joint, which is rotatably connected to a side of the first vertical plate away from the rotating cylinder, the rotating air inlet of the rotary joint is connected to a delivery pipe, the end of the delivery pipe away from the rotary joint is connected to an air pump, a positioning seat is installed under the air pump, the end of the delivery pipe away from the rotary joint is connected to the air outlet of the air pump, the rotating air outlet end of the rotary joint passes through the outer wall of the rotating cylinder and is rotatably connected to the inner air inlet cabin, and the drying heat inlet pipe is rotatably connected to the rotating air inlet of the rotary joint.
[0009] Preferably, a plurality of high temperature resistant annular hook bags are integrally formed on the outside of the conical high temperature resistant expansion bladder.
[0010] Preferably, a partition storage bag is integrally formed inside the high temperature resistant annular hook bag, and the interior of the partition storage bag is filled with iron powder.
[0011] Preferably, a bearing seat is fixedly connected to one side adjacent to the first vertical plate and the second vertical plate, and a side of the bearing seat close to the rotating cylinder is an arc-shaped surface, and a plurality of universal balls are installed on the arc-shaped surface of the rotating cylinder.
[0012] Preferably, an electromagnet is fixedly connected inside the bearing seat.
[0013] Preferably, an elastic sealing plate is fixedly connected to a side of the cover body close to the rotating cylinder.
[0014] Preferably, a plurality of reinforcing ribs are fixedly connected to the first vertical plate and the second vertical plate on one side away from the rotating drum.
[0015] Preferably, the exterior of the high temperature resistant expansion bladder is provided with a plurality of micropores, which are initially closed and open when the high temperature resistant expansion bladder expands to a specified degree. When the micropores open, the gas inside the inner air inlet cabin is ejected through the micropores.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. The present invention is connected with the inflation component through the inner air inlet cabin. During the turning over of the Mongolian medicine, gas is injected into the inner air inlet cabin through the inflation component. When the inflation component injects gas into the inner air inlet cabin, the expansion capsules will expand accordingly to form a stirring and blocking part. The stirring and blocking parts formed after the expansion capsules expand can not only further turn over and separate the medicinal materials inside the rotating drum to ensure that the medicinal materials will not be entangled during the drying process, thereby improving the uniformity and efficiency of drying, but also these stirring and blocking parts can increase the contact area between the medicinal materials and the drying gas to improve the drying effect.
[0018] 2. In the present invention, by unevenly distributing the high temperature resistant expansion capsules in the inner air inlet cabin, these capsules can form stirring and blocking parts of different shapes and angles after expansion. This design not only increases the contact area between the medicinal materials and the drying gas, but also can more effectively separate and stir them during the turning process of the medicinal materials. In particular, the conical and inclined square high temperature resistant expansion capsules can be more effectively inserted into the inside of the clumped medicinal materials, and the gas can be blown out from the inside, thereby accelerating the drying speed and reducing the agglomeration of the medicinal materials, improving the efficiency and uniformity of drying. When the conical high temperature resistant expansion capsule is inserted into the clumped medicinal materials, the high temperature resistant annular hook capsule can hook and separate the medicinal materials like a hook, further reducing the agglomeration of the medicinal materials.
[0019] 3. In the present invention, the partition storage capsule and iron powder design inside the high temperature resistant annular hook capsule, as well as the electromagnet arrangement inside the bearing seat, realize the automatic deformation and rebound of the high temperature resistant annular hook capsule after it expands and stretches to hook up the medicine. This design enables the high temperature resistant annular hook capsule to automatically loosen due to the shaking of the iron powder after hooking up the herb, and to hook up other medicines during the continuous rebound process, thereby realizing continuous and effective flipping of the medicine. This not only improves the flipping efficiency of the medicine, but also ensures that the medicine is evenly heated during the drying process. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0032] As attached Figure 1 To Attachment Figure 7 As shown:
[0033] Embodiment 1: The present invention provides a Mongolian medicine turning and drying device, comprising a first vertical plate 10 and a second vertical plate 11, wherein a rotating drum 13 is rotatably connected to one side of the first vertical plate 10 and the second vertical plate 11 adjacent to each other, and a driving motor 12 is fixedly connected to one side of the second vertical plate 11 away from the rotating drum 13, wherein an output shaft of the driving motor 12 penetrates an outer wall of the second vertical plate 11 and is fixedly connected to an outer wall of the rotating drum 13, and a feed port is provided on the outside of the rotating drum 13, and a cover body 14 is hinged on the outside of the feed port, and a side of the first vertical plate 10 away from the rotating drum 13 is rotatably connected to one side of the second vertical plate 11 The dynamic inflatable component has an inner air inlet cabin 19 fixedly connected to the interior of the rotating cylinder 13, the rotating air outlet end of the inflatable component is connected to the inner air inlet cabin 19, and the inner wall of the inner air inlet cabin 19 is integrally formed with a plurality of high-temperature resistant expansion bladders 101. The inflatable component is used to continuously inject gas into the inner air inlet cabin 19. When gas continuously enters the inner air inlet cabin 19, the high-temperature resistant expansion bladder 101 will expand, and the rotating air inlet port of the inflatable component is connected to a drying heat inlet pipe 102, and the drying heat inlet pipe 102 is connected to an external drying heat pump.
[0034] As can be seen from the above, first the staff opens the cover 14, and places the Mongolian medicine materials to be dried into the rotating drum 13 and the inner air intake chamber 19 through the feed port. After placing the medicine materials into the inner air intake chamber 19, the staff closes the cover 14, and starts the drive motor 12 to drive the rotating drum 13 to rotate. During the rotation of the rotating drum 13, the medicine materials can be turned over. During the turning over of the medicine materials, the drying high-temperature gas of the external drying heat pump is transported to the inner air intake chamber 19 through the drying heat intake pipe 102, so that the medicines are dried in the continuous turning process. During the process, gas can be continuously injected into the inner air inlet cabin 19 through the inflation component. When the gas is continuously injected into the inner air inlet cabin 19, the inner air inlet cabin 19 can be filled with gas. When the inner air inlet cabin 19 is filled with gas, the multiple high-temperature resistant expansion bladders 101 can be expanded. In the process of the expansion of the multiple high-temperature resistant expansion bladders 101, a corresponding stirring and blocking part can be formed inside the inner air inlet cabin 19. By forming the corresponding stirring and blocking part, the medicinal materials in the flipping and drying process can be further flipped and separated, so as to prevent the plant-based Mongolian medicine from gradually entangled during the continuous flipping process.
[0035] Furthermore, a plurality of micropores (not shown in the figure) are provided on the outside of the high temperature resistant expansion bladder 101. The plurality of micropores are initially closed and open when the high temperature resistant expansion bladder 101 expands to a specified degree. When the micropores open, the gas inside the inner air inlet cabin 19 is ejected through the micropores. During the overall use, the drying gas transported to the drying heat inlet pipe 102 by the mixed drying heat pump of the inflation assembly enters the inner air inlet cabin 19 together. When entering the inner air inlet cabin 19, the entire drying device can be heated, and the Mongolian medicine inside the inner air inlet cabin 19 can be dried by continuous heating and turning. Moreover, a large amount of gas enters the inner air inlet cabin 19, causing the high temperature resistant expansion bladder 101 to expand. When the high temperature resistant expansion bladder 101 expands to a specified degree, the plurality of micropores outside the high temperature resistant expansion bladder 101 will gradually open, thereby quickly ejecting the drying gas. By ejecting the drying gas, the entangled herbs can be further dispersed.
[0036] like Figure 1-Figure 6 As shown, a bearing seat 50 is fixedly connected to one side adjacent to the first vertical plate 10 and the second vertical plate 11 . The side of the bearing seat 50 close to the rotating cylinder 13 is an arc-shaped surface, and a plurality of universal balls 51 are installed on the arc-shaped surface of the rotating cylinder 13 .
[0037] Specifically, the bearing seat 50 and the universal ball 51 are arranged to support the rotating cylinder 13 in the rolling process, and the universal ball 51 assists the rotation of the rotating cylinder 13 to support the rotating cylinder 13 .
[0038] like Figure 2 As shown, the inflation component includes a rotary joint 17, which is rotatably connected to the side of the first vertical plate 10 away from the rotating cylinder 13, and the rotating air inlet of the rotary joint 17 is connected to a delivery pipe 18, and the end of the delivery pipe 18 away from the rotary joint 17 is connected to the air pump 16, and a positioning seat 15 is installed below the air pump 16. The end of the delivery pipe 18 away from the rotary joint 17 is connected to the air outlet of the air pump 16, the rotating air outlet end of the rotary joint 17 penetrates the outer wall of the rotating cylinder 13 and is rotatably connected to the inner air inlet cabin 19, and the drying heat inlet pipe 102 is rotatably connected to the rotating air inlet of the rotary joint 17.
[0039] Specifically, in the inflation assembly, not only can the drying heat inlet pipe 102 be connected through the rotary joint 17 to transport the drying gas in the external heat pump to the inner air inlet cabin 19, but the cooling gas can also be actively transported to the inner air inlet cabin 19 through the air pump 16, so that the Mongolian medicine can be further dried by blowing out alternating gas during the flipping drying process.
[0040] like Figure 1 As shown, a plurality of reinforcing ribs 60 are fixedly connected to the first vertical plate 10 and the second vertical plate 11 on one side away from the rotating drum 13 , and the plurality of reinforcing ribs 60 are provided to enhance the stability of the first vertical plate 10 and the second vertical plate 11 during the rotation of the rotating drum 13 .
[0041] like Figure 4 As shown, an elastic sealing plate 70 is fixedly connected to one side of the cover body 14 close to the rotating cylinder 13 , and the feed port opened outside the rotating cylinder 13 is blocked by the elastic sealing plate 70 .
[0042] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that, considering that most plant Mongolian medicines will be entangled during the tumbling and drying process, and the entangled Mongolian medicines cannot be separated well by simply toggling, therefore, the present application proposes the following technical solutions to solve the above technical problems, specifically:
[0043] like Figure 5 As shown, the high temperature resistant expansion bladders 101 are unevenly distributed on the inner wall of the inner air intake cabin 19. Some of the high temperature resistant expansion bladders 101 are cone-shaped after expansion, while other parts of the high temperature resistant expansion bladders 101 are inclined square-shaped after expansion. The outside of the conical high temperature resistant expansion bladder 101 is integrally formed with multiple high temperature resistant annular hook bladders 20.
[0044] From the above, it can be seen that the unevenly distributed inner air inlet cabin 19 can separate the Mongolian medicine to different degrees, and the conical inner air inlet cabin 19 can be inserted into the inside of the herbs that have been turned into a ball, so as to blow out gas inside, which not only speeds up the drying speed of the medicine, but also can further reduce the phenomenon of the medicines pulling each other and agglomerating.
[0045] Furthermore, during the continuous expansion of the high-temperature resistant expansion bladder 101, the high-temperature resistant annular hook bag 20 located outside the high-temperature resistant expansion bladder 101 will gradually expand and expand in a hook shape. During the expansion process in a hook shape, the high-temperature resistant annular hook bag 20 can hook out the medicine when the high-temperature resistant expansion bladder 101 is inserted into the clumped medicine, thereby decomposing the agglomeration of the medicine inside.
[0046] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that, although the medicine is hooked out and continuously turned over by the high temperature resistant annular hook bag 20, the medicine hooked by the high temperature resistant annular hook bag 20 is limited during the long drying process, and the high temperature resistant annular hook bag 20 cannot actively release the hooked medicine and re-hook other medicines when the gas is continuously filled. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically:
[0047] like Figure 6-Figure 7 As shown, a partition storage bag 30 is integrally formed inside the high temperature resistant annular hook bag 20 , the interior of the partition storage bag 30 is filled with iron powder 31 , and an electromagnet 40 is fixedly connected to the interior of the bearing seat 50 .
[0048] From the above, it can be seen that when the high temperature resistant annular hook bag 20 is in the process of expanding and extending to hook up the medicine, as the rotating cylinder 13 continues to flip and rotate, the iron powder 31 located inside the high temperature resistant annular hook bag 20 and the partition storage bag 30 will gradually shake. When the iron powder 31 shakes inside the partition storage bag 30 and the high temperature resistant annular hook bag 20, the high temperature resistant annular hook bag 20 can be deformed and rebound after deformation. When the high temperature resistant annular hook bag 20 hooks up the herbs and is deformed due to the shaking of the iron powder 31, the hooked medicine can be released, and other medicines can be hooked up during the continuous rebound process, and the medicines can be further continuously flipped.
[0049] Furthermore, by setting the electromagnet 40, the electromagnet 40 can be turned on intermittently. When the electromagnet 40 is turned on, the iron powder 31 inside the partition storage bag 30 can be adsorbed. When the iron powder 31 is in the adsorbed state, it will drive the high temperature resistant expansion bag 101 to actively deform, so that the high temperature resistant expansion bag 101 is bent. When the rotating cylinder 13 drives the bent and deformed high temperature resistant expansion bag 101 away from the electromagnet 40, the electromagnet 40 will actively rebound. Through active bending and rebound, the medicine can be continuously picked up and flipped inside the inner air inlet cabin 19, further improving the effect of drug drying.
[0050] Specifically, the partition storage capsule 30 and the iron powder 31 design inside the high temperature resistant annular hook capsule 20 realize automatic deformation and rebound after the high temperature resistant annular hook capsule 20 expands and stretches to hook up the medicine. After hooking up the herbs, the high temperature resistant annular hook capsule 20 can automatically loosen due to the shaking of the iron powder 31, and hook up other medicines in the process of continuous rebound, thereby realizing continuous and effective flipping of the medicine, which not only improves the flipping efficiency of the medicine, but also ensures that the medicine is evenly heated during the drying process. Moreover, as the electromagnet 40 is turned on, the high temperature resistant expansion capsule 101 can be driven as a whole to pick up the medicine. The amount of medicine picked up by the conical high temperature resistant expansion capsule 101 and the rhombus-shaped high temperature resistant expansion capsule 101 are different, and the flipping conditions are also very different, thereby further improving the effect of drug drying.
[0051] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
