Description

Technical Field

[0001] This utility model relates to the field of chrysanthemum tea production equipment, specifically a sorting device for chrysanthemum tea production. Background Technology

[0002] Chrysanthemum tea is a traditional herbal tea beverage with a long history and widespread popularity. Its main ingredient is high-quality chrysanthemums. The production process is extremely meticulous, requiring rigorous flower harvesting, careful air-drying, scientific sun-drying and steaming, and precise roasting, among many other steps. Chrysanthemums possess a unique sweet and bitter flavor, are naturally cold-resistant, and in Traditional Chinese Medicine, they are considered to have various medicinal values, including dispelling wind and clearing heat, clearing the liver and improving eyesight, and detoxifying and reducing inflammation. In the overall processing of chrysanthemum tea, the sorting stage is crucial; the level of detail in this stage directly affects the quality grade and market value of the finished product.

[0003] Currently, the industry mainly relies on manual sorting. However, this method is not only costly but also slow, and the size standards for manual sorting are inconsistent. Vibrating screens are also used for sorting flower tea, but these devices have significant shortcomings: their operation relies heavily on the friction and collision between the screen and the material to achieve sorting. This mechanical force can easily damage delicate petals, significantly affecting the integrity and quality of the flower tea. Although there are some air-separation devices on the market, most of these devices adopt a simple vertical uniform airflow design, which can only efficiently separate denser impurities such as stones and metals. They struggle to accurately distinguish between lightweight petals and stamens, resulting in sorting precision far from meeting the requirements of high-quality flower tea production. Utility Model Content

[0004] In order to overcome some of the problems mentioned in the background above, this invention provides a sorting device for chrysanthemum tea production.

[0005] The technical solution adopted by this utility model is as follows: A sorting device for chrysanthemum tea production, comprising: The multi-stage sorting mechanism is connected from top to bottom to form a material channel, including a feeding guide structure and a spiral guide channel; An airflow generating mechanism is located below the multi-stage sorting mechanism. Its air outlet is connected to the sorting area and is equipped with an airflow swirl component, so that the airflow entering the sorting area is in a spiral upward shape. A light impurity separation mechanism is located on the side of the feed guide structure, and achieves the separation of light impurities based on the density difference between the spiral rising airflow and the material. The flower tea collection port is connected to the end of the spiral guide channel and is used to collect the sorted flower tea. The feeding guide structure directs the material to the sorting area, and the spiral guide channel guides the flower tea along the spiral path to the flower tea collection mechanism.

[0006] Furthermore, the feed guiding structure includes a feed zone, which includes a feed cylinder and a baffle. The baffle is disposed inside the feed cylinder, and a feed inlet and a light impurity separation mechanism are respectively provided on both sides of the baffle. The bottom of the baffle is provided with an inclined part, the inclined part is at an angle of 30°-45° with the horizontal plane, and is inclined towards the feed inlet, the inclined part extends to the spiral guide channel; The top of the feed cylinder is provided with a top cover.

[0007] Furthermore, the sorting zone includes a sorting cylinder, the spiral guide channel is fixedly connected to the inner wall of the sorting cylinder, the top of the sorting cylinder is connected to the bottom of the feed cylinder, and the bottom of the sorting cylinder is connected to the air outlet of the airflow generating mechanism.

[0008] Furthermore, the airflow generating mechanism also includes an air inlet duct, which is connected to an external blower, and the airflow swirl assembly is disposed inside the air inlet duct; The airflow swirl assembly includes a base plate and multiple air guide plates, which cause the airflow to enter the sorting area in a spiral upward shape.

[0009] Furthermore, the air guide plate is an arc-shaped blade, and multiple air guide plates are evenly distributed circumferentially around the center of the substrate. The included angle between adjacent air guide plates is 15°-25°, and the air guide height increases from the edge of the air inlet to the center, forming a vortex airflow acceleration zone.

[0010] Furthermore, the surface of the spiral guide channel is covered with a flexible pad, and the surface of the flexible pad is provided with anti-slip texture.

[0011] Furthermore, the light impurity separation mechanism includes an impurity screen cylinder and a connecting plate. The impurity screen cylinder is inclined, with one end passing through the feed cylinder and fixedly connected to the baffle. The other end of the impurity screen cylinder is connected to an external collection bag through the connecting plate.

[0012] The beneficial effects of this utility model are: A spiral upward airflow is used to create a centrifugal force gradient, causing light impurities to float and separate, while heavy petals sink and are collected, achieving effective separation of light impurities. The separated impurities are discharged through an independent light impurity separation mechanism to avoid secondary contamination, thus improving both the sorting efficiency and accuracy of flower tea materials.

[0013] Using wind power to sort the flower tea materials can effectively prevent the petals from breaking and improve the quality of the flower tea. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1-6 As shown, in some embodiments, a sorting device for chrysanthemum tea production includes: The multi-stage sorting mechanism, as the core component of the entire device, is connected from top to bottom to form a material channel, including a feed guide structure and a spiral guide channel 52. Specifically, the washed flower tea material enters the sorting zone 5 through the feed guide structure. The material is sorted by gravity under the influence of airflow. Material that meets the weight requirements is guided through the spiral guide channel 52 and discharged through the flower tea collection port 4, completing the sorting operation.

[0019] The airflow generating mechanism 3, serving as the power source, is located below the multi-stage sorting mechanism. Its air outlet is directly connected to the sorting zone 5, and it is used to introduce spiral airflow into the sorting mechanism. To achieve this function, the mechanism is equipped with an airflow directional component, which precisely controls the airflow direction to make the airflow entering the sorting zone 5 spiral upward, ensuring a stable spiral upward shape and guaranteeing the uniformity and stability of the sorting process.

[0020] The light impurity separation mechanism 7, located on the side of the feed guide structure, serves as the output mechanism for light impurities. Its working principle utilizes the density difference between the spiraling upward airflow and the material to carry the light impurities away from the main sorting area, achieving effective separation. The separated impurities are discharged through an independent discharge channel to avoid secondary contamination.

[0021] The flower tea collection port 4, as the final collection component, is connected to the end outlet of the spiral guide channel 52 and is specifically used to collect high-quality flower tea products after sorting.

[0022] The specific sorting principle of this embodiment is as follows: the external blower delivers airflow to the sorting zone 5 through the airflow generating mechanism 3, and the airflow swirl component converts the airflow into a spiral upward airflow, forming a centrifugal force field. The outer swirling layer of the spiral airflow has a high flow velocity and low pressure, while the inner swirling layer (central region) has a low flow velocity and high pressure, forming a transverse pressure gradient.

[0023] Light impurities (broken petals, calyxes, etc.) in the raw materials of scented tea are discharged from the light impurity separation mechanism 7 at the top by the centrifugal force of the spiral airflow. Intact petals penetrate the airflow layer due to gravity and fall onto the surface of the spiral guide channel 52. The petals then travel along the spiral guide channel 52 to the scented tea collection port 4.

[0024] It is worth noting that a spiral upward airflow is used to create a centrifugal force gradient, causing light impurities to float and separate, while heavy petals sink and are collected, thus achieving effective separation of light impurities. The separated impurities are discharged through an independent light impurity separation mechanism 7, avoiding secondary contamination. This improves both the sorting efficiency and quality of the flower tea materials, ensuring the quality of the sorted flower tea.

[0025] Furthermore, in some embodiments, the feed guiding structure includes a feed zone 6, which includes a feed cylinder 61 and a baffle 62. The feed cylinder 61 has a cylindrical structure, and the baffle 62 divides its interior into two completely symmetrical working areas. The feed inlet 2 is located in the working area on the left side of the baffle 62, while the light impurity separation mechanism 7 is located in the working area on the right side of the baffle 62.

[0026] Of particular note is the meticulously designed bottom of baffle 62, which employs a unique inclined structure. This inclined section maintains an optimal working angle of 30°-45° with the horizontal plane, and the inclined direction is intentionally directed towards the feed inlet 2. This design facilitates the smooth flow of materials and effectively prevents material accumulation and blockage. This inclined section extends downwards to the top of the spiral guide channel 52, forming a continuous, stable, and efficient material conveying path.

[0027] In addition, to ensure the safety of the sorting process, an openable top cover 1 is specially configured on the top of the feed cylinder 61. The top cover 1 is equipped with a rubber sealing ring and a quick locking device, which can effectively prevent external impurities from entering and keep the internal working environment clean, while facilitating daily maintenance and cleaning by operators.

[0028] Furthermore, in some embodiments, the sorting zone 5 includes a sorting cylinder 51, and the spiral guide channel 52 is arranged along the inner wall of the sorting cylinder 51, fixing the two together to form a stable structure.

[0029] The top of the sorting cylinder 51 is connected to the bottom of the feed cylinder 61, and the bottom of the sorting cylinder 51 is connected to the air outlet of the airflow generating mechanism 3.

[0030] The upper opening of the sorting cylinder 51 is sealed to the lower outlet of the feed cylinder 61 with screws, ensuring that materials can smoothly enter the sorting area. The bottom of the sorting cylinder 51 is designed with a conical structure, which is sealed to the air outlet of the airflow generating mechanism 3 through a pipe connector, allowing the airflow to be blown evenly from the bottom to the top, forming a stable airflow sorting environment. This structural design ensures both the material sorting effect and the sealing and stability of the entire device.

[0031] Furthermore, in some embodiments, the airflow generating mechanism 3 also includes an air inlet duct 31, which is airtightly connected to the air outlet of an external blower via a flange connector, and the airflow swirl assembly is disposed within the cavity of the air inlet duct 31.

[0032] The airflow swirl assembly consists of a circular base plate 33 and multiple guide vanes 32 evenly distributed along the circumference. The base plate 33 is a circular boss with a ramp around its perimeter, which guides the airflow to the guide vanes 32. These guide vanes 32 are installed at a specific angle of 15-30 degrees on the upper surface platform of the base plate 33, and each guide vane 32 can precisely guide the incoming airflow to form a stable spiral upward motion trajectory.

[0033] A through hole is provided at the center of the substrate 33, which connects the sorting area 5 and the flower tea collection port 4 through the entire airflow generating mechanism 3.

[0034] Through this special design, the airflow can form a uniform vortex state within the air inlet duct 31, thereby smoothly delivering the airflow into the sorting area in a uniform spiral upward shape. This spiral upward airflow shape can effectively improve the sorting efficiency of flower tea materials, ensure the efficient separation of flower tea from impurities, and achieve high-precision sorting of flower tea raw materials.

[0035] Furthermore, the air guide plate 32 adopts a specially designed arc-shaped blade structure. Multiple air guide plates 32 are evenly distributed along the circumference with the center of the substrate 33 as the center point. The center angle between two adjacent air guide plates 32 is controlled within the preferred range of 15° to 25°. This angle design can ensure the uniformity of airflow distribution. This design can guide the airflow to form a stable vortex motion, thereby creating a highly efficient vortex airflow acceleration zone inside the device, significantly improving sorting efficiency.

[0036] Furthermore, in some embodiments, the entire working surface of the spiral guide channel 52 is covered with a specially designed flexible buffer pad layer, which has good elasticity and wear resistance. Simultaneously, the surface of the flexible pad is precision-machined with a uniformly distributed anti-slip texture structure. These textures are arranged in an interlaced grid or wave pattern, ensuring smooth flow of the flower tea raw materials during the sorting process while effectively preventing slippage or accumulation, thereby significantly improving sorting efficiency and product quality.

[0037] Furthermore, in some embodiments, the light impurity separation mechanism 7 includes an impurity screen cylinder 71 and a connecting plate 72. The impurity screen cylinder 71 is installed at an angle, effectively discharging light impurities entering the screen cylinder and preventing their accumulation, thus improving separation efficiency. One end of the impurity screen cylinder 71 passes through the feed cylinder 61 and forms a secure connection with the baffle 62, ensuring the stability of the screen cylinder 71 during operation. The other end of the impurity screen cylinder 71 is connected to an external collection device via the connecting plate 72. This collection device preferably uses a detachable collection bag design for easy periodic cleaning and replacement of impurities. This structural design ensures both effective impurity separation and ease of operation.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
