Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicinal material processing, in particular to a dehydration device for preliminary processing of Chinese medicinal materials before drying. Background Art

[0002] In the manufacturing process of Chinese herbal medicines, in order to ensure that the herbs can be stored for a long time, the herbs are usually heated and dried quickly. For stem and leaf Chinese herbs, there is a lot of water between the stems and leaves after washing. Direct drying will affect the drying efficiency, so dehydration is required.

[0003] In the prior art, centrifugal equipment is used to dehydrate Chinese herbal medicines. For example, patent CN212930777U proposes a device for dehydrating herbal medicines. The device performs centrifugal dehydration of Chinese herbal medicines by rotating a drum, and a resistance block is arranged inside the drum to prevent the accumulation of herbal medicines on the inner wall of the drum. However, in the actual centrifugal dehydration process, since the resistance block is fixedly connected to the drum, the herbal medicines will be stably attached to the inner wall of the drum and the surface of the resistance block under the action of a stable centrifugal force, and the resistance block cannot play a good role in preventing the accumulation of herbal medicines. Utility Model Content

[0004] The utility model aims at the problem that when the centrifugal dehydration device in the prior art dehydrates Chinese medicinal materials, the medicinal materials are piled up on the inner wall of the rotating drum, thus affecting the dehydration effect, and proposes a dehydration device for preliminary processing of Chinese medicinal materials before drying.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A dehydration device for preliminary processing of Chinese medicinal materials before drying comprises a base, a box body and a cover plate. The base is located at the lower part of the box body to form a seal at the lower part of the box body, the cover plate is located at the upper part of the box body to form a seal at the upper part of the box body, and the cover plate is detachably connected to the box body for opening the box body.

[0007] The box body is cylindrical, and a dehydration cylinder and a rotating bottom plate are arranged coaxially with the box body. The rotating bottom plate is located inside the dehydration cylinder, and the inner wall of the dehydration cylinder is rotatably connected to the outer edge of the rotating bottom plate. The bottom of the rotating bottom plate is fixedly connected to a dehydration motor, and the dehydration motor can drive the rotating bottom plate to rotate.

[0008] Furthermore, the base is configured to connect the rotating bottom plate and the dehydration cylinder to form a combined assembly in which the rotating bottom plate and the dehydration cylinder rotate synchronously.

[0009] Preferably, the coupling assembly includes an outer coupling rod, an inner coupling rod, a rotating coupling plate, a fixed coupling plate and a coupling cylinder. The outer coupling rod and the inner coupling rod form a coupling rod group, and a plurality of coupling rod groups are arranged on the rotating coupling plate with the axis of the rotating coupling plate as the center, and the outer coupling rod is located on the outer side of the inner coupling rod. The outer coupling rod is located below the dehydration cylinder and is used to couple with the dehydration cylinder; the inner coupling rod is located below the rotating bottom plate and is used to couple with the rotating bottom plate. The coupling cylinder is used to realize the axial movement of the outer coupling rod and the inner coupling rod along the rotating bottom plate, so that the outer coupling rod is separated or coupled with the dehydration cylinder and the inner coupling rod is separated or coupled with the rotating bottom plate.

[0010] Furthermore, the rotating combined plate and the fixed combined plate are coaxially arranged with the rotating base plate, the rotating combined plate is located above the fixed combined plate, and the rotating combined plate and the fixed combined plate are rotatably connected via a slewing bearing. The outer combined rod and the inner combined rod are fixedly connected to the top surface of the rotating combined plate, and the working end of the combined cylinder is fixedly connected to the bottom surface of the outer fixed combined plate. The rotating combined plate and the fixed combined plate are axially movably connected to the base on the rotating base plate, and the combined cylinder is fixedly connected to the base. The combined cylinder pushes the rotating combined plate and the fixed combined plate to move axially.

[0011] There is a drainage space between the housing and the dehydration cylinder of the dehydration device, and a drainage pipe is arranged at the bottom of the drainage space. A dehydration hole is arranged on the dehydration cylinder. When the dehydration cylinder is combined with the rotating bottom plate, the dehydration cylinder and the rotating bottom plate rotate synchronously. The dehydration cylinder realizes centrifugal dehydration of the medicinal materials inside the dehydration cylinder through rotation, and the water on the medicinal materials enters the drainage space through the dehydration hole of the dehydration cylinder and is then discharged from the drainage pipe.

[0012] The rotating bottom plate is provided with a scraper plate inside the dehydration cylinder. The scraper plate is arranged on the edge of the rotating bottom plate with the axis of the rotating bottom plate as the center, and the scraper plate is attached to the inner wall of the dehydration cylinder. During the dehydration process, after the rotation speed of the dehydration cylinder is stable, the medicinal materials will be stably attached to the inner wall of the dehydration cylinder and the surface of the scraper plate. At this time, the connection between the dehydration cylinder and the rotating bottom plate is released, the rotation speed of the dehydration cylinder slows down, and the scraper plate moves relative to the dehydration cylinder. The scraper plate can scrape the medicinal materials inside the dehydration cylinder. At the same time, the medicinal materials also move relative to the dehydration cylinder. The medicinal materials are no longer attached to the wall, and the position of the medicinal materials inside the dehydration cylinder is disrupted. Then, the connection between the dehydration cylinder and the rotating bottom plate is maintained again to continue dehydrating the medicinal materials.

[0013] The beneficial effects of the utility model are as follows: the dehydration device is used for centrifugal dehydration treatment of Chinese medicinal materials before drying. The dehydration cylinder and the rotating bottom plate are rotatably connected and can be separated and combined. The dehydration cylinder and the rotating bottom plate are combined and rotate synchronously to realize centrifugal dehydration. The dehydration cylinder and the rotating bottom plate are separated and relatively rotated. The scraper plate can scrape the medicinal materials inside the dehydration cylinder, and the medicinal materials are no longer attached to the wall, thereby avoiding the accumulation of medicinal materials, and improving the efficiency of medicinal material dehydration and the uniformity of dehydration.

The bottom of the rotating bottom plate 5 is fixedly connected to a dehydration motor 9, and the dehydration motor 9 can drive the rotating bottom plate 5 to rotate.

[0023] Furthermore, the base 1 is configured to connect the rotating bottom plate 5 and the dehydration cylinder 4 to form a coupling assembly 7 for synchronous rotation of the rotating bottom plate 5 and the dehydration cylinder 4 .

[0024] refer to Figure 3 and Figure 4In this embodiment, the coupling assembly 7 includes an outer coupling rod 71, an inner coupling rod 72, a rotating coupling plate 73, a fixed coupling plate 74 and a coupling cylinder 76. The outer coupling rod 71 and the inner coupling rod 72 form a coupling rod group, and a plurality of coupling rod groups are arranged around the rotating coupling plate 73 with the axis of the rotating coupling plate 73 as the center, and the outer coupling rod 71 is located on the outside of the inner coupling rod 72.
