Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, specifically a purification device for processing loose black tea. Background Technology

[0002] Dark tea is a fermented tea mainly produced in Hunan, Yunnan, and Guangxi provinces of China. Its production process includes fixing, rolling, fermentation, and drying, resulting in a dark color, mellow taste, and unique aroma. Common types of dark tea include Pu'er tea (divided into raw and ripe varieties), Fu brick tea from Hunan, and Liubao tea from Guangxi. Dark tea is believed to aid digestion, lower cholesterol and promote weight loss, and has antioxidant properties. It is rich in nutrients and is widely loved.

[0003] An investigation revealed that a Chinese utility model discloses a purification device for black tea processing (publication number: CN218014058U), comprising a support frame. Several springs are fixedly connected to the top of the inner surfaces of both sides of the support frame. Connecting plates are respectively arranged near the top of the inner surfaces of both sides of the support frame. Two connecting plates are provided, and the opposite sides of the two connecting plates are respectively fixedly connected to one end of an adjacent set of springs. Ring-shaped components are rotatably connected to the opposite sides of the two connecting plates. A housing is provided between the two connecting plates. A vibration motor is fixedly connected to the center of the outer surface of one side of the housing, and a drive motor is arranged at the center of the outer surface of the other side of the housing. A connecting column is fixedly connected to the center of the side of the drive motor away from the housing. Filter plates are fixedly connected to the inner surfaces of both sides of the housing near the top and bottom, respectively. Two limiting blocks are symmetrically fixedly connected to the bottom side of the upper filter plate, and an electric push rod is fixedly connected to the other bottom side of the upper filter plate. A baffle is fixedly connected to the telescopic end of the electric push rod.

[0004] While the aforementioned patent facilitates the fixation of the relative positions of the connecting plate and the ring-shaped component through a rotating connection, thereby ensuring the stability of the outer shell, and the spring design ensures that when the outer shell drives the connecting plate to vibrate, the spring sways accordingly, and the support frame does not experience significant vibration, the rotating connection between the ring-shaped component and the connecting plate also allows the outer shell to drive the ring-shaped component to rotate while the connecting plate remains stationary. However, in the aforementioned patent, the outer shell and the filter plate rotate synchronously. Due to inertia, impurities that fall into the outer shell cannot completely fall off, causing them to re-enter the filter plate during rotation. This results in low filtration efficiency, and the lighter impurities inside the black tea tend to adhere to its surface, making it difficult to remove them through filtration alone, thus leading to poor impurity removal.

[0005] Therefore, this utility model provides a device for removing impurities during the processing of loose black tea to solve the above-mentioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a device for removing impurities during the processing of loose black tea, such as... Figure 1 - Figure 4 As shown, a cleaning device for processing loose black tea includes a base plate 1, an outer protective assembly fixedly connected to the upper surface of the base plate 1, a screening assembly fixedly installed on one side of the outer protective assembly, a feed inlet opened on the outer surface of the screening assembly, and a sealing assembly fixedly connected inside the feed inlet.

[0026] The screening assembly includes a first motor 2, one side of which is fixedly installed on one side of the outer protective assembly. The output end of the first motor 2 is fixedly connected to a transmission rod 3, and one end of the transmission rod 3 is fixedly connected to a screening screen cylinder 4. A blower 5 is fixedly installed on one side of the screening screen cylinder 4. When the external power supply starts the first motor 2, it drives the transmission rod 3 to rotate, causing the screening screen cylinder 4 to rotate, thereby screening out impurities in the black tea. During the rotation, the black tea is repeatedly turned over, which can prevent the screening screen cylinder 4 from clogging. The outer cylinder 8 is in a stationary state, which can prevent impurities screened into the outer cylinder 8 from re-entering the screening screen cylinder 4, thus ensuring filtration efficiency. At the same time, during the rotation of the screening screen cylinder 4, the blower 5, which is started by the external power supply, blows into its interior, which can blow light impurities on the surface of the black tea to the perforated plate end on one side of the screening screen cylinder 4, and then enter the outer cylinder 8 and be discharged from the impurity outlet, which can improve the impurity removal effect.

[0027] The outer protective assembly includes a support plate 6, the bottom end of which is fixedly connected to the upper surface of the base plate 1. A through groove is provided on the inner side of the support plate 6, and a connecting rod 7 is fixedly connected inside the through groove. An outer cylinder 8 is fixedly connected to the inner end of the connecting rod 7. An outlet for impurities is provided at one end of the lower surface of the outer cylinder 8. The support plate 6 supports the connecting rod 7, so that the outer cylinder 8 is at a suitable height and is fixed to prevent it from rotating with the screening screen cylinder 4, thus preventing impurities inside it from entering the screening screen cylinder 4. At the same time, the outlet for impurities is located at one end, which facilitates the flow of impurities and can guide the airflow of the blower 5, facilitating the smooth flow of light impurities.

[0028] The sealing assembly includes a frame 9, the outer surface of which is fixedly connected to the inside of the feed inlet. A slot is provided on the upper surface of the frame 9, and a magnetic block 10 is engaged inside the slot. A sealing plate 11 is fixedly connected to one side of the lower surface of the magnetic block 10, and a first handle 12 is fixedly connected to the upper surface of the sealing plate 11. The magnetic block 10 and the frame 9 are in a magnetic attraction state. After the black tea to be screened is added into the screening cylinder 4 through the feed inlet, the magnetic block 10 is engaged into the slot and is attracted to the slot. The sealing plate 11 is then connected and fixed to the frame 9, thereby sealing the feed inlet and preventing the black tea raw material inside the screening cylinder 4 from leaking out from here during the screening process.

[0029] A square groove is provided on the upper surface of the outer cylinder 8, and a sealing component is fixedly connected inside the square groove.

[0030] The sealing assembly includes a feed frame 13, the outer surface of which is fixedly connected to the inside of a square groove. A sealing cover 14 is snapped onto the upper surface of the feed frame 13. A second handle 15 is fixedly connected to both sides of the sealing cover 14. By holding the second handle 15, the sealing cover 14 is placed inside the feed frame 13, thereby sealing the feed frame 13 and preventing the airflow from the blower 5 from flowing out, which would result in insufficient removal of light impurities on the black tea.

[0031] One end of the screening cylinder 4 is set as a solid plate, and the other end is set as a perforated plate. A blower 5 is installed on the outside of the solid plate to blow air to one side of the perforated plate, which facilitates the outflow of light impurities.

[0032] Working steps: First, after adding the black tea to be screened into the screening cylinder 4 through the feed inlet, the magnetic block 10 is snapped into the slot and adsorbed inside the slot. The sealing plate 11 is then connected and fixed to the frame 9 to seal the feed inlet. Next, the second handle 15 is held to attach the sealing cover 14 to the feed frame 13 to seal the feed frame 13. Then, the external power supply starts the first motor 2, which drives the transmission rod 3 to rotate, causing the screening cylinder 4 to rotate and thus remove impurities from the black tea. Finally, during the rotation of the screening cylinder 4, the external power supply starts the blower 5, which blows light impurities on the surface of the black tea to the perforated plate end on one side of the screening cylinder 4, and then into the outer cylinder 8, and discharged through the impurity outlet.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
