Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a tea air separation and impurity removal device. Background Technology
[0002] Tea is a traditional Chinese beverage that is popular among consumers for its health benefits and disease prevention properties. The general processing of tea includes steps such as fresh leaf treatment, withering, fixation, rolling, chopping, fermentation, drying, and pan-frying. In current tea processing techniques, tea leaves often contain impurities such as dust, sand, and yellowish-green leaves after being picked from the mountains. Even after the basic processing is completed, impurities such as dust and broken tea leaves may still be present. Therefore, after the fresh leaf treatment and pan-frying processes, the tea leaves need to be sorted.
[0003] In existing technologies, dust and small debris are separated from tea leaves by air blowing during the falling process. However, the tea leaves tend to concentrate during the falling process, which means that not all dust and debris can be removed, resulting in poor impurity removal and requiring multiple air separation processes, which is inefficient.
[0004] Therefore, in view of the problems of poor impurity removal effect and low impurity removal efficiency of existing air separation and impurity removal devices, there is a need for an impurity removal device that can solve the above problems. Utility Model Content
[0005] In order to solve the problems of poor impurity removal effect and low impurity removal efficiency of existing air separation and impurity removal devices, this application provides a tea air separation and impurity removal device.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A tea leaf air separation and impurity removal device includes a box body. A feed inlet is located at the center of the upper side of the box body. A dispersing box is fixedly connected to the outside of the feed inlet on the upper side of the box body. A rotating shaft is rotatably connected to the center of the dispersing box. A dispersing roller is fixedly connected to the outside of the rotating shaft. A material-dispersing rod for dispersing tea leaves is fixedly connected to the outside of the dispersing roller. A hopper is connected to the top of the dispersing box via an adjusting assembly. A mounting plate is fixedly connected to the inside of the right end of the box body. A fan is fixedly connected to the center of the mounting plate. A triangular plate for guiding flow is fixedly connected to the lower side of the inner wall of the left end of the box body. A flow-guiding assembly is provided in the center of the box body.
[0008] As a further improvement of this utility model, the adjusting component includes a feeding pipe fixedly connected to the bottom of the hopper, an adjusting plate is provided on the left side inside the feeding pipe, a rotating rod is fixedly connected to the top of the adjusting plate, and the end of the rotating rod is rotatably connected to the inside of the upper end of the feeding pipe.
[0009] As a further improvement of this utility model, the adjusting assembly also includes arc-shaped openings at both ends of the feeding tube, with a movable rod movably connected inside the arc-shaped opening. The opposite ends of the movable rods are respectively fixedly connected to the middle of the front and rear ends of the adjusting plate, and fasteners for fixing are threaded onto the outside of the movable rods.
[0010] As a further improvement of this utility model, a motor is fixedly connected to the front side of the dispersion box, and the drive end of the motor is fixedly connected to the front end of the rotating shaft.
[0011] As a further improvement of this utility model, the flow guiding assembly includes a fixed plate fixedly connected to the front side of the housing, a flow guiding plate fixedly connected to the rear side of the fixed plate, and the rear ends of the flow guiding plate respectively passing through the interior of the housing.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0016] 1. In this utility model, by installing a dispersing roller with a feeding rod inside the dispersing box, and driving the rotating shaft with a motor to rotate the dispersing roller, the tea leaves entering from the hopper can be effectively dispersed, allowing the tea leaves to enter the box evenly. A fan generates airflow, which, in conjunction with a triangular plate and a flow guide assembly, effectively separates the tea leaves from impurities. Impurities are discharged from the first flow guide pipe, while qualified tea leaves flow out from the discharge port through the second flow guide pipe, achieving efficient air separation and impurity removal of the tea leaves and ensuring tea quality.
[0017] 2.

[0029] Example 1: A tea leaf winnowing and impurity removal device includes a housing 1, with a feed inlet 2 at the upper center of the housing 1. A dispersing box 3 is fixedly connected to the outside of the upper side of the housing 1 corresponding to the feed inlet 2. A rotating shaft 4 is rotatably connected to the center of the dispersing box 3. A dispersing roller 5 is fixedly connected to the outside of the rotating shaft 4. A dispersing rod 6 for dispersing tea leaves is fixedly connected to the outside of the dispersing roller 5. A motor 24 is fixedly connected to the front side of the dispersing box 3. The drive end of the motor 24 is fixedly connected to the front end of the rotating shaft 4. A hopper 7 is provided on the top of the dispersing box 3. A mounting plate 10 is fixedly connected to the inside of the right end of the body 1. A fan 11 is fixedly connected to the middle of the mounting plate 10. A triangular plate 16 for guiding flow is fixedly connected to the lower side of the inner wall of the left end of the body 1. A partition plate 12 for protection is fixedly connected to the right end of the body 1. A discharge port 9 is opened in the middle of the lower side of the body 1. A second guide pipe 14 is fixedly connected to the outside of the lower side of the body 1 corresponding to the discharge port 9. A first guide pipe 13 for discharging impurities is fixedly connected to the left end of the body 1. A base 15 is fixedly connected to the lower left end of the body 1.
[0030] The tea leaves to be processed are poured into the device through the hopper 7, which conveys the tea leaves to the dispersion box 3. Inside the dispersion box 3, the motor 24 drives the rotating shaft 4 to rotate, causing the dispersion roller 5 and its feed lever 6, which are fixed to the outside of the rotating shaft 4, to rotate. The feed lever 6 disperses the tea leaves entering the dispersion box 3, ensuring that the tea leaves enter the subsequent processing area more evenly, preventing tea leaf accumulation, and guaranteeing the effectiveness of the subsequent air separation process. This achieves efficient air separation and impurity removal of the tea leaves, ensuring tea quality. After the blower 11 is started, airflow is generated inside the box 1. The airflow exerts a force on the dispersed tea leaves, removing lighter impurities. The airflow will blow the impurities towards the left end of the box 1. The triangular plate 16 at the left end of the box 1 acts as a guide, directing the blown impurities to the first guide pipe 13. The impurities are discharged from the box 1 through the first guide pipe 13. The settled tea leaves are discharged through the discharge port 9 opened in the middle of the lower side of the box 1. The second guide pipe 14, which is fixedly connected to the outside, can guide the tea leaves to the collection point. The partition 12 at the right end of the box 1 serves as a protective measure to prevent the fan 11 and other components from being interfered with or damaged by the outside. The base 15 at the lower left end of the box 1 provides stable support for the entire device, ensuring the stability of the device during operation.
[0031] Example 2: A feeding pipe 17 is fixedly connected to the bottom of the hopper 7. An adjusting plate 18 is provided on the left side inside the feeding pipe 17. A rotating rod 19 is fixedly connected to the top of the adjusting plate 18. The end of the rotating rod 19 is rotatably connected to the upper end of the feeding pipe 17. Arc-shaped openings 20 are provided at both the front and rear ends of the feeding pipe 17. A movable rod 21 is movably connected inside the arc-shaped openings 20. The opposite ends of the movable rod 21 are fixedly connected to the middle of the front and rear ends of the adjusting plate 18, respectively. Fasteners 22 for fixing are threaded onto the outside of the movable rod 21.
[0032] The adjustable plate 18 can be rotated by the movable rod 21, which can change the angle of the adjustable plate 18 inside the feed tube 17, thereby adjusting the opening size of the feed tube 17. When the adjustable plate 18 rotates, it drives the movable rod 21 in the middle of the front and rear ends to move within the arc-shaped opening 20. The movable rod 21 is fixed with fasteners 22 to fix the adjustable plate 18 in the required position, so as to achieve precise control of the feed amount and thus ensure the effect of tea winnowing.
[0033] As one of the optimized structural designs for Example 1, such as Figures 1-3 As shown, a fixing plate 23 is fixedly connected to the front side of the housing 1, and a guide plate 8 is fixedly connected to the rear side of the fixing plate 23. The rear ends of the guide plate 8 are respectively inserted into the interior of the housing 1.
[0034] The guide plate 8 is fixed to the front side of the box 1 by the fixing plate 23, and the rear end is inserted into the box 1. It can guide and adjust the flow path of the falling tea leaves and impurities to a certain extent, ensuring that the tea leaves and impurities can enter the feed port 9 and the first guide pipe 13 respectively according to the predetermined path, while increasing the time for the tea leaves to be air-separated and improving the air-separation effect.
[0035] Working principle: The tea leaves to be processed are poured into the device through the hopper 7. The feed pipe 17 at the bottom of the hopper 7 conveys the tea leaves to the dispersion box 3. The motor 24 inside the dispersion box 3 drives the rotating shaft 4 to rotate, which in turn drives the dispersion roller 5 and the feeding rod 6 fixed outside the rotating shaft 4 to rotate. The feeding rod 6 disperses the tea leaves entering the dispersion box 3, so that the tea leaves can enter the subsequent processing area more evenly, avoiding the accumulation of tea leaves and ensuring the effect of the subsequent air separation process. The blower 11 is installed in the middle of the mounting plate 10 on the right end of the box body 1. After the blower 11 is started, airflow will be generated in the box body. The airflow will exert a force on the dispersed tea leaves. Lighter impurities will be blown by the airflow to the left end of the box body 1. The triangular plate 16 at the left end of the box body 1 acts as a guide, directing the blown impurities to the first guide pipe 13. The impurities are discharged through the first guide pipe 13. The settled tea leaves exit the box 1 through the discharge port 9 located in the middle of the lower side of the box 1. The second guide pipe 14, which is fixedly connected to the outside of the box 1, guides the tea leaves to the collection point. The guide plate 8 is fixed to the front of the box 1 by the fixing plate 23, and its rear end passes through the inside of the box 1. It can guide and adjust the flow path of the falling tea leaves and impurities to ensure that the tea leaves and impurities can enter the discharge port 9 and the first guide pipe 13 respectively according to the predetermined path. By rotating the rotating rod 19 at the top of the adjusting plate 18, the angle of the adjusting plate 18 in the discharge pipe 17 can be changed, thereby adjusting the opening size of the discharge pipe 17. The movable rod 21 in the middle of the front and rear ends of the adjusting plate 18 moves within the arc-shaped opening 20. The movable rod 21 is fixed with fasteners 22 to fix the adjusting plate 18 in the required position, so as to achieve precise control of the discharge amount.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
