Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a mesh belt drying machine for solid medicinal slices. Background Art

[0002] Solid herbal slices refer to tablets made from herbs as the main raw materials. They have the characteristics of maintaining the original form and efficacy of herbs. Due to their convenience in carrying, easy storage and use, solid herbal slices are widely used in the field of traditional Chinese medicine. In the production of Chinese herbal slices, there are specific requirements for the moisture content of Chinese medicinal materials to ensure the quality of the final product. Therefore, a mesh belt dryer is needed to dry the materials.

[0003] The existing public technology has a publication number of CN218337628U. A mesh belt continuous fruit and vegetable drying machine includes a frame and a drying chamber fixed on the frame. A sleeve drying assembly and a driving assembly for driving the sleeve drying assembly to rotate are rotatably matched in the drying chamber. A mesh belt transmission belt is arranged in the sleeve drying assembly, and both ends of the mesh belt transmission belt extend to the outside of the drying chamber. The utility model has a simple structure, and the driving assembly drives the sleeve drying assembly to perform circumferential drying of fruits and vegetables.

[0004] However, the above patent still has certain disadvantages when used: when drying materials, the materials are usually directly input onto the mesh belt for drying. Since the materials on the mesh belt will accumulate, some of the materials in the lower layer cannot be effectively dried, which leads to poor uniformity of the drying process and fails to achieve the ideal processing effect. Moreover, as the mesh belt time increases and the amount of medicinal materials in contact increases, impurities will adhere to the surface of the mesh belt, thereby clogging the holes on the surface of the mesh belt, resulting in the inability to fully transfer heat to the medicinal materials, affecting the overall drying effect. There are certain defects in its use.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0032] In one embodiment, a lower air guide plate 3 is installed in the middle position inside the mesh belt dryer body 9, support rods 2 are symmetrically installed at the bottom ends of the two side surfaces of the lower air guide plate 3, and the bottom of the support rod 2 is welded to the top surface of the bottom plate 1, connecting rods 10 are symmetrically welded in the middle position of the two side surfaces of the lower air guide plate 3, and an upper air guide plate 11 is fixedly installed at the top position of the connecting rod 10, and several groups of nozzles 6 are provided on the surface of the lower air guide plate 3 and the upper air guide plate 11. The nozzle 6 is configured to spray hot air, thereby achieving the purpose of drying the solid medicinal pieces on the surface of the mesh belt.

[0033] In one embodiment, an air energy heat pump 4 is fixedly installed at a position on one side of the top of the bottom plate 1. The air energy heat pump 4 is respectively connected to the lower air guide plate 3 and the upper air guide plate 11 through an air supply pipe 5. The air energy heat pump 4 adopts the same structure as a mesh belt continuous fruit and vegetable dryer with a publication number of CN218337628U in the existing public technology, which will not be elaborated here.

[0034] In one embodiment, cavities are provided inside the lower air guide plate 3 and the upper air guide plate 11 for hot air to flow and enter the nozzle 6. The provision of the cavities facilitates the circulation of hot air.

[0035] In one embodiment, a plurality of groups of support frames 7 are symmetrically installed on the top surface of the lower air guide plate 3. A tipping hopper 13 is rotatably connected to the top surface of the support frame 7 through a rotating shaft 14. One end of the rotating shaft 14 passes through one side of the support frame 7 and is connected to a motor 12.

Moreover, when the solid medicinal slices move, they will be blocked by the tipping hopper 13 many times, and enter the tipping hopper 13 under the movement trend of the mesh belt, and then the operation of the motor 12 can drive the rotating shaft 14 to rotate, and then the tipping hopper 13 is rotated. When the tipping hopper 13 rotates to the top, the solid medicinal slices collected inside it will fall off, thereby causing the position of the accumulated medicinal slices to change and expose the medicinal slices in the middle position. The hopper 13 is provided with a plurality of groups, so the operation time of the hoppers 13 at different positions can be controlled to have a certain interval, so that the hoppers 13 that have not been collected by the previous group of hoppers 13 can be collected by the hoppers at the rear, thereby ensuring that the hoppers can be more fully turned, thereby improving the overall drying quality, and when the mesh belt rotates to the bottom, its surface will be blocked by the abutting scraper 16, so that the scraper 16 can scrape off the impurities attached to its surface, and at the same time, the scraped surface will be wiped by the brush roller 15 and the scraper 16 is scraped for the second time, so as to remove the impurities attached to the mesh belt surface as much as possible, and realize the cleaning operation of the mesh belt surface, so as to avoid the residual impurities from contaminating the subsequent solid medicinal slices and ensure the smoothness of the gaps on the mesh belt surface, so that the heat can be smoothly transferred, and the drying effect of the medicinal slices is guaranteed.
