Description

Technical Field

[0001] This utility model relates to the field of Dendrobium processing technology, and in particular to a Dendrobium officinale air separator with dust removal function. Background Technology

[0002] Drying is a crucial step in the processing of Dendrobium officinale. Its purpose is to remove moisture from the Dendrobium officinale, facilitating subsequent storage, transportation, and further processing. However, after drying, a certain amount of impurities often remain on the surface and inside of the Dendrobium officinale. If these impurities are not effectively removed, they will affect the appearance quality of the Dendrobium officinale. Therefore, effective impurity and dust removal after drying Dendrobium officinale is a key step in ensuring product quality.

[0003] To achieve the aforementioned goals of impurity and dust removal, air separation equipment is widely used in the processing of Dendrobium officinale. Air separation equipment utilizes the differences in physical properties such as density and particle size between Dendrobium officinale and impurities, using wind power to separate impurities and dust from the Dendrobium officinale, thus purifying it. However, in practical applications, traditional air separation equipment for Dendrobium officinale has certain limitations, affecting the quality and efficiency of air separation. One prominent problem lies in the feeding stage. Traditional equipment typically uses a conveyor belt to directly transport the dried Dendrobium officinale into the air separation box. The Dendrobium officinale on the conveyor belt is often piled up, leading to uneven distribution within the air separation box. In some areas, the Dendrobium officinale is piled too thickly, making it difficult for wind to penetrate and preventing the separation of impurities. In other areas, the Dendrobium officinale may be too sparse, resulting in excessive wind force and potentially blowing away some qualified Dendrobium officinale particles. This uneven feeding condition severely affects the stability and consistency of the air separation direction, reducing the accuracy and effectiveness of air separation. Therefore, the traditional equipment is improved by scraping the piles of Dendrobium officinale on the conveyor belt during the discharge process. This creates a uniform and flat material layer before the Dendrobium officinale enters the air separation box, allowing it to enter with a more uniform thickness and thus improving the efficiency of air separation. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a Dendrobium officinale air separator with dust removal function, which can scrape the piles of Dendrobium officinale on the conveyor belt during the discharge process, so that it forms a uniform material layer and enters the air separator box, thereby improving the air separator efficiency.

[0005] The technical implementation scheme of this utility model is as follows:

[0006] A dust removal air separator for Dendrobium officinale includes a fixed frame, an air separator box, a feeding hopper, a leveling mechanism, and an air separator. The fixed frame has a rectangular frame structure, and the feeding hopper, air separator, and leveling mechanism are located on the upper part of the fixed frame.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] like Figures 1-5 The aforementioned air separator for Dendrobium officinale with dust removal function includes a fixed frame 1, an air separator box 4, a feeding hopper 7, a smoothing mechanism 3, and an air separator mechanism 5. The fixed frame 1 has a rectangular frame structure, and the feeding hopper 7, the air separator mechanism 5, and the smoothing mechanism 3 are arranged on the upper part of the fixed frame 1. The smoothing mechanism 3 includes a support frame 301, a receiving plate 302, a screw 304, a lifting plate 307, a scraper bar 305, and a smoothing plate 306. The lifting plate 307 is connected by two... The end of the slide groove is slidably connected to the slide bar 303 on the inner wall of the support frame 301, and the lifting plate 307 is connected to the screw hole on the receiving plate 302 through the screw 304; the lower part of the lifting plate 307 is provided with a number of scraper bars 305, and one end of the scraper bar 305 is provided with a smoothing plate 306; the smoothing plate 306 is movably connected to the fixing ear at the bottom of the lifting plate 307 through the rotating shafts at both ends, and a torsion spring is provided at the connection between the rotating shaft and the fixing ear of the smoothing plate 306.

[0025] It should be noted that during the processing of Dendrobium, the dried Dendrobium needs to undergo air separation to remove impurities, debris, and dust. Traditional air separation equipment generally uses a combination of hoppers and conveyor belts to separate the Dendrobium that falls from the conveyor belt. The separation is achieved through the combined force of gravity and the airflow generated by the Dendrobium. However, in traditional air separation equipment, the Dendrobium on the conveyor belt often piles up in large quantities. This piled-in approach leads to uneven distribution of the Dendrobium within the air separation box. In some areas, the Dendrobium officinale piles up too thickly, making it difficult for wind to penetrate and preventing impurities from being fully separated. This results in the wind separation efficiency not meeting expectations. To address this, the wind separation equipment was improved by installing a first guide platform 501 and a feeding hopper 7 on the upper part of the fixed frame 1. As the Dendrobium officinale enters the first conveyor belt of the first guide platform 501 from the feeding hopper 7, it undergoes a first dispersion process by the disperser 13 and is then transported by the first conveyor belt. During this process, the leveling mechanism 3 performs wind separation and leveling operations to disperse the piled Dendrobium officinale.

[0026] It should be further explained that the lifting plate 307 is slidably connected to the slide bar 303 through the slide grooves at both ends. The distance between the scraper bar 305 and the smoothing plate 306 and the first conveyor belt can be adjusted by adjusting the height of the screw 304. The scraper bar 305 and the smoothing plate 306 are set at the bottom of the smoothing plate 306. The Dendrobium can be dispersed by the scraper bar 305 and then leveled by the inclined smoothing plate 306. Moreover, the entire smoothing plate 306 is connected to the fixed ear through the rotating shaft and the torsion spring, so that the smoothing plate 306 has elastic stress. It can not only realize the leveling operation, but also turn corners when encountering small stones or Dendrobium that has agglomerated, avoiding hard contact that could damage the parts.

[0027] like Figures 1-6 As shown, the air separation mechanism 5 includes a first guide platform 501, a first conveyor belt 502, an air guide channel 503, an air guide box 504, a first air guide plate 508, and a smoothing mechanism 3. The first guide platform 501 is equipped with the first conveyor belt 502, and the smoothing mechanism 3 is installed on the upper part of the first conveyor belt 502. The air guide channel 503 is installed inside the fixed frame 1, and the air guide box 504 and the first air guide plate 508 are installed inside the air guide channel 503. One end of the first air guide plate 508 is connected to the adjustment group 12. The feed hopper 7 is connected to one end of the fixed frame 1 through the support plate 6, and a disperser 13 is installed at the outlet of the feed hopper 7.

[0028] It should be noted that the air separation mechanism 5 is set up to perform air separation on the Dendrobium after it has been scraped flat. An air guide channel 503 is set inside the fixed frame 1, and an air guide box 504 is set inside the air guide channel 503. The airflow generated by the air guide fan 505 is gathered and sprayed out through the air guide cover 506, and then enters the air separation box 4 through the first air guide plate 508 to perform air separation on the Dendrobium that has fallen from the first conveyor belt, removing impurities and dust from its interior.

[0029] It should be further explained that the first air guide plate 508 is movably set inside the air guide channel 503 through the rotating shafts at both ends, and one end of the rotating shaft is connected to the adjustment group 12. The angle of the entire first air guide plate 508 can be adjusted through the adjustment group 12, thereby adjusting the angle of the air outlet, which is used for air separation of Dendrobium with different humidity levels.

[0030] like Figures 1-6 As shown, the adjustment group 12 includes a first gear 1201, a second gear 1203, a bearing seat, and a rotating handle 1202. The first gear 1201 is mounted on the rotating shaft and meshes with the second gear 1203 on the bearing seat. One end of the rotating shaft is connected to the rotating handle 1202.

[0031] It should be noted that in this structure, the first gear 1201 is fixedly mounted on the rotating shaft, forming a stable linkage structure. Simultaneously, the first gear 1201 and the second gear 1203 on the bearing housing are meshed together, ensuring the stability and accuracy of power transmission. When the second gear 1203 rotates, the meshing action of the two gears efficiently transmits power to the first gear 1201, thereby driving the entire rotating shaft to rotate synchronously. The rotation of the shaft directly affects the angle adjustment of the first air guide plate 508. Through this series of transmission actions, the angle of the first air guide plate 508 can be easily controlled, meeting the air guiding requirements in different scenarios.

[0032] like Figures 1-6 As shown, the air classifier 4 is provided with a second guide platform 9 inside, and a second conveyor belt 10 is provided on the upper part of the second guide platform 9; the air classifier 4 is provided with a guide trough 11 inside, and the discharge port of the guide trough 11 is correspondingly provided with the second guide platform 9; the exhaust port 8 at one end of the air classifier 4 is connected to the dust collector through an air guide pipe, and a second air guide plate 14 is provided at one end of the exhaust port 8; the disperser 13 is a rectangular cavity structure with openings at the top and bottom, and a number of guide plates are provided inside the disperser 13 to form a guide channel structure.

[0033] It should be noted that the second guide platform 9 is located inside the air separator 4 and is used to receive and transfer qualified Dendrobium after air separation. During the operation, Dendrobium falls from the first conveyor belt and is then air-separated by air shower. Since the Dendrobium strips are relatively heavy, they will fall into the guide chute 11 and enter the second guide platform 9 for transfer after being collected by the guide chute 11. Meanwhile, lighter dust and impurities will follow the airflow into the exhaust port 8 and then enter the outgoing equipment for separation.

[0034] It should be further explained that the second air guide plate 14 is set to redirect the airflow and guide it into the exhaust port 8, so as to facilitate the diversion of dust.

[0035] It should be further explained that the disperser 13 is equipped with multiple guide plates to form a material guiding channel structure. After the material enters it, it will be dispersed and discharged through the material guiding channel, reducing the accumulation of Dendrobium after discharge.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
