Description

Technical Field

[0001] This utility model belongs to the field of tea impurity removal technology, and in particular relates to a tea grading and impurity removal device. Background Technology

[0002] Tea impurity removal is a crucial step in ensuring the purity, safety, and quality of tea. It generally occurs during the tea processing stage. Existing technologies include methods such as air separation, electrostatic separation, sorting, and sieving. However, due to multiple considerations of efficiency and cost, most equipment uses sieving to remove impurities from tea. Regardless of the type of equipment, generally speaking, a single device usually only uses one method for screening, resulting in limited impurity removal. If multiple devices are used for multiple impurity removal processes, problems such as large footprint and high energy consumption will arise, and secondary breakage is likely to occur during material transfer. Therefore, it is necessary to design a tea grading and impurity removal device. Utility Model Content

A collection box is provided inside the screening box, with one end of the collection box extending to one side of the screening box and the other end extending below the top of the fourth mounting block. The top of the fourth mounting block is inclined.

[0006] Preferably, the rotating drum is inclined, and the height of the side of the rotating drum near the secondary impurity removal box is lower than the height of the other side of the rotating drum.

[0015] Example Example: A preferred embodiment of the tea grading and impurity removal device provided by this utility model is as follows Figures 1 to 4 As shown: A tea grading and impurity removal device includes a base 13, with multiple support rods 12 installed on one side of the top of the base 13, and a sieving box 27 installed on the top of the support rods 12. A secondary impurity removal box 26 is installed on one side of the sieving box 27. A rotating cylinder 6 is installed inside the sieving box 27, and multiple arc-shaped baffles 7 are installed on the inner wall of the rotating cylinder 6. Multiple sieve holes are penetrating the outer wall of the rotating cylinder 6. One end of the rotating cylinder 6 extends into the interior of the secondary impurity removal box 26, and a guide hopper 25 is fixed to the inner wall of the secondary impurity removal box 26. A servo motor 18 is installed at the center of the bottom of the secondary impurity removal box 26, and the output end of the servo motor 18 extends to the bottom of the guide hopper 25 and is equipped with a rotating disk 24. Multiple retaining rings 23 are provided at the bottom of the interior of the secondary impurity removal box 26, and multiple connecting rods 22 are fixed between the outer wall of the multiple retaining rings 23 and the inner wall of the secondary impurity removal box 26. Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, after the tea leaves enter the rotating drum 6, they move along the outer wall of the drum 6. During this process, the arc-shaped baffle 7 blocks the tea leaves to prevent them from sliding down at high speed. At the same time, the rotating drum 6 rotates continuously, ensuring that the tea leaves can slide down through the gaps in the arc-shaped baffle 7. The tea leaves are also slightly turned over, so that small impurities and tea fragments can leave the rotating drum 6 through the sieve holes. Subsequently, the tea leaves inside the rotating drum 6 are sent to the guide hopper 25 for collection by gravity, and then guided to the continuously rotating disc 24. The disc 24 throws the objects sent above it out. Objects of different masses are thrown out at different distances by centrifugal force, thus falling into different positions, further classifying impurities, plump tea leaves and shriveled tea leaves, and achieving the purpose of secondary impurity removal.

[0016] A second mounting block 5 is installed on one side of the top of the screening box 27, a first mounting block 3 is installed on one side of the screening box 27, a third mounting block 9 is installed on the other side of the top of the screening box 27, and a fourth mounting block 14 is installed on one side of the bottom of the screening box 27. The rotating cylinder 6 is connected to one end of the first mounting block 3, the second mounting block 5, the third mounting block 9 and the fourth mounting block 14 through a bearing. A collection box 4 is provided inside the screening box 27, and one end of the collection box 4 extends to one side of the screening box 27, and the other end of the collection box 4 extends to the bottom of the top side of the fourth mounting block 14. The top of the fourth mounting block 14 is inclined. The rotating drum 6 is inclined, and the height of the side of the rotating drum 6 near the secondary impurity removal box 26 is lower than the height of the other side of the rotating drum 6. A feed hopper 1 is installed on the top of one side of the screening box 27, and a guide pipe 2 is connected to the bottom of the feed hopper 1. One end of the guide pipe 2 extends into the interior of the rotating drum 6. A geared motor 8 is mounted on one side of the third mounting block 9, and the output end of the geared motor 8 extends to the other side of the third mounting block 9 and is equipped with a gear 10. A gear ring 11 that meshes with the gear is fixed to one end of the outer wall of the rotating cylinder 6. Specifically, such as Figure 1 As shown, untreated tea leaves can be fed into the feed hopper 1 and smoothly enter the interior of the rotating drum 6. By starting the reduction motor 8, the gear 10 is driven to rotate. With the transmission of the gear 10 and the gear ring 11, the rotating drum 6 can be rotated. The first mounting block 3, the second mounting block 5, the third mounting block 9 and the fourth mounting block 14 can achieve stable installation of the rotating drum 6 and ensure its stable rotation. The impurities screened out from the rotating drum 6 will fall into the collection box 4, or fall on the fourth mounting block 14 and eventually slide into the collection box 4.

[0017] The bottom of the secondary impurity removal box 26 is equipped with multiple annular discharge hoppers 20, and the annular discharge hoppers 20 are all circular in shape. A positioning plate 15 is installed on one side of the top of the base 13. A collection box 21 is provided on one side of the positioning plate 15. A fixing plate 19 is provided inside the collection box 21. A second collection groove 17 is installed on the outer wall of the fixing plate 19. A first collection groove 16 is provided on the outer side of the second collection groove 17. The interior of the fixing plate 19 has multiple vertically penetrating positioning holes, and the bottom center of the collection box 21 has multiple matching positioning posts installed therein. Specifically, such as Figure 1 and Figure 2 As shown, the annular hopper 20 can receive and guide the tea leaves between each baffle ring 23, allowing them to leave the secondary impurity removal box 26. With the help of the positioning pin and positioning hole, the fixing plate 19 can be quickly installed, thereby fixing the position of the second collection trough 17. Then, the first collection trough 16 is placed on the outside of the second collection trough 17, thus fixing the position of the first collection trough 16. At this time, the collection box 21 is moved so that its edge is attached to the inner edge of the positioning plate 15, quickly completing the positioning of the collection box 21. In this way, apart from the first collection trough 16 and the second collection trough 17, there is still a ring of space inside the collection box 21. These three spaces can correspond to the three annular hoppers 20, completing the reception of the leaked material at the annular hoppers 20.
