Description

Technical Field

[0001] The present invention relates to the technical field of drying, in particular to self-adaptive temperature-controlled drying equipment for flaky Chinese medicinal materials. Background Art

[0002] When drying flaked Chinese medicinal materials, the drying temperature and drying time need to be controlled. Over-drying is not allowed. Over-drying can easily lead to the loss of medicinal properties. Therefore, the medicinal materials need to be made more uniform during the drying process. Directly turning the flaked Chinese medicinal materials over and circulating them for drying can easily cause the flaked Chinese medicinal materials to be damaged, affecting the drying quality. Moreover, when one side of the flaked Chinese medicinal materials is dried, the other side is prone to retain moisture when there is no direct hot air blowing. When the other side is dried, if the moisture is taken away too quickly, the temperature inside the Chinese medicinal materials may be too high, which may lead to the loss or denaturation of the medicinal components. Summary of the Invention

[0003] The present invention provides a self-adaptive temperature-controlled drying device for flaky Chinese medicinal materials, which solves the shortcomings of the prior art in how to evenly dry flaky medicinal materials and how to avoid the loss of medicinal components due to excessive moisture removal when drying flaky medicinal materials by alternating single-sided blowing.

[0030] When the air supply pipe 6 is fully closed, the air supply pipe 6 is gradually opened, and the air supply pipe 6 is gradually opened from opening to closing. The air supply pipe 5 is installed on the main air pipe 4. The air supply pipe 6 is opened, and the air supply pipe 6 is opened. The air supply pipe 5 is opened, and the air supply pipe 6 is opened.

The air supply pipe 5 and the air supply pipe 6 are opened, and the air supply pipe 4 is opened.

[0031] The drying tray includes a frame, in which a plurality of third rotating shafts 24 are installed through bearings, and a disc 23 is installed on the third rotating shaft 24. A second gear 25 is installed at the end of the third rotating shaft 24. A bracket 12 is installed between the airflow distribution discs 15, and a sliding rack 19 is installed on one side of the bracket 12, which is driven to slide back and forth by the first rotating shaft 3. The sliding rack 19 is provided with a slide groove along the length direction, and one end of the first driving rod 27 and the second driving rod 20 is slidably connected to the slide groove. The size of the drying tray is smaller than the airflow distribution disc 15, so that all the medicinal materials on the drying tray can be dried. When the drying tray is fixed on the bracket 12, the second gear 25 is engaged with the rack, and the outer edge of the disc 23 is provided with an anti-slip lever. The third rotating shaft 24 is driven to rotate by the first rotating shaft 3, thereby changing the support point of the sheet-like Chinese medicinal materials to avoid dead corners in the sheet-like Chinese medicinal materials during the drying process.

[0032] An extension rod 18 is fixed at both ends of the sliding rack 19, and the extension rod 18 extends into the sealing cavity 16 and is fixedly connected to the extrusion plate 17. A through hole is provided on the extrusion plate 17, and the sealing cavity 16 contains a non-Newtonian fluid. The sealing cavity 16 is fixedly connected to the bracket 12. A first cross bar 13 and a second cross bar 26 are fixed on the sliding rack 19. The first cross bar 13 and the second cross bar 26 are fixedly connected to the first driving rod 27 and the second driving rod 20 through a spring 21. A cam 22 is fixedly mounted on the first rotating shaft 3. The cam 22 is located between the first driving rod 27 and the second driving rod 20. The diameter change distance of the cam 22 is greater than the length of the sealing cavity 16, and the deformation distance of the spring 21 is greater than the cam 2 2, the cam 22 is driven to rotate by the first bearing. The rotation of the cam 22 will push the first drive rod 27 and the second drive rod 20 in a gap, thereby pushing the first cross bar 13 and the second cross bar 26 in a gap. When the first cross bar 13 or the second cross bar 26 is subjected to a force along the length direction of the sliding rack 19, the sliding rack 19 will move in the direction of the force. The movement process pushes the extrusion plate 17 to move, and the movement of the extrusion plate 17 will apply a force to the non-Newtonian fluid. By controlling the size of the cam 22, sufficient force can be provided. Due to the characteristics of the non-Newtonian fluid, the sliding rack 19 can still move at a uniform speed when subjected to different forces.

[0033] The working principle of this application is:

[0034] By arranging the air flow evenly distributing plates 15 corresponding to the upper and lower arrangements, the air flow is evenly distributed. In the same component, when the upper air flow evenly distributing plate 15 is exhausting air, the lower air flow evenly distributing plate 15 will supply air, thereby increasing the drying air flow in the vertical direction. When the upper air flow evenly distributing plate 15 switches to supplying air, similarly, the lower air flow evenly distributing plate 15 will exhaust air. At the same time, the first rotating shaft 3 can simultaneously drive all the air flow evenly distributing plates 15 to rotate and switch between exhausting and supplying air, thereby providing the drying tray with a drying air flow from top to bottom and from bottom to top in the vertical direction, and the drying air flow is evenly distributed through the air flow evenly distributing plate 15. At the same time, the air flow is evenly distributed by rotating the air flow evenly distributing plate 15, that is, the drying air flow from bottom to top and from top to bottom can be provided to the Chinese medicine sheets without turning over the Chinese medicine sheets.

[0035] Moreover, during the air supply and exhaust process, the air flow of the air supply changes from small to large, thereby providing a smaller drying air flow. As the second rotating shaft 8 rotates, the arc-shaped sealing block 7 is driven to rotate, thereby gradually changing the opening, so that the air flow rate changes from low to large, giving the medicinal materials time to adapt. The method of gradually increasing the hot air volume can remove moisture more gently and reduce the impact on the medicinal properties of the Chinese medicinal materials. Gradually increasing the hot air volume can make the drying process more uniform and reduce the moisture difference between the inside and outside of the Chinese medicinal materials. This method can avoid the rapid removal of moisture causing the temperature of the Chinese medicinal materials to rise too quickly, thereby better maintaining the medicinal efficacy of the Chinese medicinal materials.

[0036] The drying tray is composed of a plurality of evenly spaced third rotating shafts 24, on which evenly spaced discs 23 are arranged. The tops of the discs 23 serve as point supports for the Chinese medicine sheets. The third rotating shafts 24 are driven by the first rotating shaft 3 to rotate so as to adjust the position of the Chinese medicine sheets and the discs 23 as point supports, thereby ensuring that there are no dead corners on the support surface during the drying process.

[0037] The rotation of the cam 22 can drive the first drive rod 27 and the second drive rod 20 to move along the length direction of the sliding rack 19, thereby compressing the spring 21. When the spring 21 is compressed, it will provide a force on the first cross bar 13 or the second cross bar 26 along the length direction of the sliding rack 19. Since the two ends of the sliding rack 19 are connected to the extension rod 18, the extension rod 18 extends into the sealing cavity 16 and is fixedly connected to the extrusion plate 17, due to the action of non-Newtonian fluid, the sliding rack 19 can move at a uniform speed when it is moved by force, and the sliding rack 19 will not move too fast due to changes in the magnitude of the force, making the process of supporting point conversion of the Chinese medicine sheet more stable, avoiding the accumulation of Chinese medicine sheets caused by excessive changes.

[0038] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.

Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
