Description

Technical Field

[0001] This invention belongs to the field of tea refining technology, and particularly relates to a separation device and separation method for tea refining. Background Technology

[0002] Tea refining is the process of processing raw tea into commercial tea. The main purpose of tea refining is to improve the appearance, classify grades, increase purity, adjust quality, enhance aroma, and fully realize the economic value of the raw materials through processes such as winnowing and sieving.

[0003] Because existing tea refining techniques are not effective at separating tea leaves, it is difficult to select tea leaves that meet the requirements, resulting in a decrease in tea quality. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a separation device and method for tea refining, which can improve the separation effect of tea, thereby effectively screening out tea that meets the requirements and thus improving the quality of tea.

[0005] In view of this, the present invention provides a separation device and a separation method for tea refining, comprising a shell, wherein the shell contains: A separation device for separating tea leaves multiple times; A conveying device is provided at the feeding end of the outer shell and is connected to a separating device. The conveying device is used to convey tea leaves to the separating device.

[0006] In this technical solution, by setting a separation device and a conveying device inside the outer shell, the process of tea from feeding to separation can be automated. The conveying device stably transports the tea to be processed to the separation device, which can perform multiple separation operations on the tea, gradually removing unqualified tea impurities and low-quality tea, ensuring that the final selected tea meets the standards of commercial tea in terms of appearance and purity, so as to improve the overall quality of tea refining.

[0007] Furthermore, the separation device includes: The first separation mechanism is located at the discharge end of the conveying device and is used for the initial separation of tea leaves. The second separation mechanism is located on the top of the outer casing and is connected to the first separation mechanism. The first separation mechanism is used to further separate the tea leaves that meet the requirements in the initial separation. The third separation mechanism is located at the end of the outer shell. The third separation mechanism and the first separation mechanism are used to further separate the tea leaves that do not meet the requirements in the second separation.

[0008] In this technical solution, a multi-level separation system is formed by refining the separation device into first, second, and third separation mechanisms. The first separation mechanism serves as the starting point of the separation process, performing preliminary screening on the tea leaves conveyed by the conveying device and classifying them into two categories according to certain standards: those that meet the requirements and those that do not. The tea leaves that meet the requirements are then conveyed to the second separation mechanism located outside the outer shell for more refined secondary separation to further improve the quality of the tea leaves. The tea leaves that do not meet the requirements after the secondary separation enter the third separation mechanism inside the outer shell for further separation. This structural design allows different types of tea leaves to be processed accordingly, avoiding the problem of incomplete separation that may be caused by a single separation step, thereby comprehensively improving the accuracy and efficiency of tea leaf separation.

[0009] Furthermore, the first separation mechanism includes: A climbing plate is vertically installed inside the outer shell along the height direction. The inside of the climbing plate is hollow. The bottom of the climbing plate is connected to a conveying device. The climbing plate has a downward opening. One end of the climbing plate is connected to a second separation mechanism. The first air pump is fixedly installed outside the housing, and the air extraction assembly is used to extract air from the inside of the first separation mechanism.

[0010] In this technical solution, when the conveying device transports tea leaves to the lifting plate, the first suction pump starts working, generating an upward airflow suction force on the tea leaves through the hollow internal channel of the lifting plate. This causes the lighter tea leaves to be sucked into the lifting plate under the action of the airflow and move upward along the channel to the second separation mechanism, while the heavier tea leaves cannot be sucked up by the airflow due to their own weight and will slide down the surface of the lifting plate to the opening of the lifting plate, thus achieving the initial separation and screening of the tea leaves. This method of separation using airflow and gravity differences is simple to operate and has high separation efficiency, laying the foundation for subsequent fine separation.

[0011] Furthermore, the second separation mechanism includes: The chamber is fixedly installed at the top of the inner wall of the outer shell. The chamber is in the shape of an inverted trapezoid and has a downward opening. The interior of the chamber is connected to the interior of the climbing plate and is connected to the first air pump. A baffle plate is fixedly installed inside the chamber. The baffle plate is inclined away from the climbing plate. An airflow channel is provided between the baffle plate and the inner wall of the chamber. The width of the airflow channel is greater than the width of the climbing plate. An air extraction pipe is fixedly installed on the chamber, and one end of the air extraction pipe is connected to a first air extraction pump.

[0012] In this technical solution, the tea leaves entering the chamber from the climbing plate will slide downward along the inclined deflector under the action of the air flow generated by the first air pump. Since the chamber is in an inverted trapezoid shape and the width of the air flow channel is greater than the width of the climbing plate, the flow rate of the air flow in the chamber will gradually decrease, resulting in a reduction in the upward lift force of the air flow on the tea leaves during the falling process. At this time, some tea leaves with slightly greater weight will first fall to the opening at the bottom of the chamber, while the tea leaves with lighter weight will continue to move towards the inside of the first air pump through the air extraction pipe along with the air flow, thus achieving hierarchical separation.

[0013] Further, the third separation mechanism includes: A hollow plate, which is arranged inside the outer shell. The hollow plate is in a "冂" shape. There is a downward opening on the side of the hollow plate close to the chamber. One end of the hollow plate is connected to the lower end of the chamber. There is a separation pipe on the side of the hollow plate far from the chamber, and the separation pipe is connected through the outer shell; A separation chamber, which is arranged outside the outer shell. The separation chamber is fixedly connected to the separation pipe, and the separation chamber has a downward opening; A second air pump, which is arranged on one side of the separation chamber and is connected to one side of the separation chamber.

[0014] In this technical solution, when the heavier tea leaves leave the chamber and enter below the hollow plate, the second air pump starts to work, and the inside of the hollow plate is evacuated through the separation pipe. Under the guidance of the air flow, the tea leaves will move along the "冂" path of the hollow plate. Among them, the heavier tea leaves will be discharged from the opening of the hollow plate, while the relatively lighter tea leaf impurities will enter the separation chamber for further separation. The heavier ones will fall to the opening of the separation chamber, and the lighter ones will enter the second air pump. Through such a design, it is possible to perform a secondary screening on the tea leaves that still do not meet the requirements after the secondary separation, further recover the potentially utilizable tea leaves that may exist therein, reduce raw material waste, and improve the comprehensive effect of separation.

[0015] Further, an inclined plate is fixedly arranged on the inner wall of the separation chamber.

[0016] In this technical solution, when the tea leaves enter the separation chamber, the inclined plate can play a guiding role for them, enabling the tea leaf impurities to slide along the inclined direction under the dual action of their own gravity and the air flow, prolonging the residence time of the tea leaf impurities in the separation chamber, allowing the second air pump to have more sufficient time to separate impurities of different weights, and at the same time, the inclined design also avoids the accumulation of tea leaf impurities on the inner wall of the separation chamber, ensuring the smooth progress of the separation process.

[0017] Further, a collection mechanism is arranged on the separation device, and the collection mechanism is used to separate the separated tea leaves.

[0018] Furthermore, the collection mechanism includes: The first collection component is located below the climbing plate and is connected through the outer shell. The first collection component is used to collect tea leaves that do not meet the requirements after the initial separation. The second collection component is disposed below the first and second air pumps, and is used to collect the finished tea leaves from the second separation mechanism. A collection box is located below the separation chamber and is used to collect finished tea leaves that meet the requirements.

[0019] In this technical solution, the first and second collection components are belt conveyor components. Tea leaves fall from the opening of the lifting plate onto the conveyor belt of the first collection component and are transported to the collection area outside the outer shell. The second collection component is used to receive the lighter tea leaves separated from the first and second suction pumps. The second collection component conveys the collected tea leaves into the collection box. The collection box is placed directly below the separation chamber. The finished tea leaves discharged from the opening of the separation chamber fall naturally into the collection box under the action of gravity, realizing the classification and collection of different separation results, avoiding the mixing of tea leaves, and facilitating the subsequent separate processing of various types of tea leaves.

[0020] Furthermore, the separation device is equipped with a wind-blocking mechanism, which is used to seal the chamber and the separation chamber.

[0021] In this technical solution, the windbreak mechanism can effectively prevent external airflow from entering the chamber and the separation chamber, thereby ensuring the stability of airflow velocity and pressure during the tea separation process and further improving the accuracy and reliability of the separation.

[0022] Furthermore, the windbreak mechanism includes: A first windbreak shaft is rotatably disposed at the bottom of the chamber. The first windbreak shaft is provided with a plurality of windbreak blocks along the circumferential direction, and the windbreak blocks are in contact with the interior of the chamber. The second windshield shaft is rotatably mounted at the bottom of the separation chamber. The second windshield shaft has multiple windshield plates arranged along the circumferential direction, and the windshield plates are in contact with the interior of the separation chamber.

[0023] In this technical solution, when the tea leaves are discharged from the bottom opening of the chamber, they will come into contact with the baffle block on the first baffle shaft, pushing the baffle block to drive the first baffle shaft to rotate. At this time, the baffle block rotates with the shaft to open the opening. Similarly, when the tea leaves and impurities are discharged, the baffle plate of the second baffle shaft at the bottom of the separation chamber is impacted and rotates to open the channel. This structure can not only ensure that the tea leaves are discharged smoothly, but also minimize the leakage of airflow in the chamber and the separation chamber, maintain the stability of the internal airflow environment, and ensure the continuous and efficient operation of the separation.

[0024] A separation device and a separation method for tea refining are disclosed. Based on the aforementioned separation device for tea refining, the separation method includes the following steps: S1. Tea feeding: Tea leaves enter the interior of the outer shell through the feed port and are conveyed to the separation device by the conveying device; S2. Tea Leaf Separation: The conveying device transports the tea leaves to the climbing plate of the first separation mechanism. The first suction pump generates an upward airflow, and the lighter tea leaves are sucked into the climbing plate and conveyed to the second separation mechanism. The tea leaves entering the second separation mechanism are guided by the guide plate and the airflow. The heavier tea leaves fall into the bottom opening of the chamber, while the lighter tea leaves are carried by the airflow through the suction pipe into the second collection assembly. After the second separation, the heavier tea leaves enter the third separation mechanism. In the third separation mechanism, the second suction pump draws air through the separation pipe, causing the tea leaves to move along the hollow plate. The heavier tea leaves are discharged from the opening of the hollow plate, while the lighter tea leaves enter the separation chamber. After being guided by the inclined plate, the tea leaves fall into the collection box.

[0025] S3, Tea Collection: Tea leaves that do not meet the requirements in the first separation mechanism slide down the climbing plate to the first collection component and leave the shell. Lighter tea leaves in the second and third separation mechanisms enter the second collection component with the airflow and enter the collection box under the transmission of the second collection component. At the same time, tea leaves that meet the requirements in the separation chamber also fall into the collection box.

[0026] The beneficial effects of this invention are: 1. By setting a separation device and a conveying device inside the outer shell, the tea can be processed from feeding to separation. The conveying device stably transports the tea to be processed to the separation device. The separation device can perform multiple separation operations on the tea, gradually removing tea impurities and low-quality tea that do not meet the requirements, ensuring that the final selected tea meets the standards of commercial tea in terms of appearance and purity, so as to improve the overall quality of tea refining.

[0033] Example 1: like Figure 1-5 As shown, the present invention provides a separation device 3 for tea refining and a separation method thereof, including a housing 1, wherein the housing 1 is provided with: Separation device 3, which is used to separate tea leaves multiple times; The conveying device 2 is located at the feeding end of the outer shell 1 and is connected to the separating device 3. The conveying device 2 is used to convey tea leaves to the separating device 3.

[0034] By setting a separation device 3 and a conveying device 2 inside the outer shell 1, the tea can be automated from feeding to separation. The conveying device 2 stably transports the tea to be processed to the separation device 3. The separation device 3 can perform multiple separation operations on the tea, gradually removing tea impurities and low-quality tea that do not meet the requirements, ensuring that the final selected tea can meet the standards of commercial tea in terms of appearance and purity, so as to improve the overall quality of tea refining.

[0035] The separation device 3 includes: The first separation mechanism 4 is located at the discharge end of the conveying device 2 and is used to perform initial separation of tea leaves. The second separation mechanism 5 is disposed on the top of the outer shell 1 and is connected to the first separation mechanism 4. The first separation mechanism 4 is used to further separate the tea leaves that meet the requirements in the initial separation. The third separation mechanism 6 is located at the end of the outer shell 1. The third separation mechanism 6 and the first separation mechanism 4 are used to further separate the tea leaves that do not meet the requirements in the secondary separation.

[0036] By refining the separation device 3 into first, second, and third separation mechanisms 6, a multi-level separation system is formed. The first separation mechanism 4 serves as the starting point of the separation process, performing preliminary screening on the tea leaves conveyed by the conveying device 2, and classifying the tea leaves into two categories according to certain standards: those that meet the requirements and those that do not. The tea leaves that meet the requirements are conveyed to the second separation mechanism 5 located outside the outer shell 1 for more refined secondary separation to further improve the quality of the tea leaves. The tea leaves that do not meet the requirements after the secondary separation enter the third separation mechanism 6 inside the outer shell 1 for further separation. This structural design allows different types of tea leaves to be processed accordingly, avoiding the problem of incomplete separation that may be caused by a single separation step, thereby comprehensively improving the accuracy and efficiency of tea leaf separation.

[0037] The first separation mechanism 4 includes: The climbing plate 7 is vertically installed inside the outer shell 1 along the height direction of the outer shell 1. The inside of the climbing plate 7 is hollow. The lower part of the climbing plate 7 is connected to the conveying device 2. The climbing plate 7 has a downward opening. One end of the climbing plate 7 is connected to the second separation mechanism 5. The first air pump 8 is fixedly installed on the outside of the housing 1, and the air pumping assembly is used to pump air from the inside of the first separation mechanism 4.

[0038] When the conveying device 2 delivers tea leaves to the lifting plate 7, the first suction pump 8 starts working, generating an upward airflow suction force on the tea leaves through the internal channel of the hollow lifting plate 7. This causes the lighter tea leaves to be sucked into the lifting plate 7 by the airflow and move upward along the channel to the second separation mechanism 5, while the heavier tea leaves cannot be sucked up by the airflow due to their own weight and will slide down the surface of the lifting plate 7 to the opening of the lifting plate 7, thus achieving the initial separation and screening of the tea leaves. This method of separation using airflow and gravity differences is simple to operate and has high separation efficiency, laying the foundation for subsequent fine separation.

[0039] The second separation mechanism 5 includes: Chamber 9 is fixedly arranged at the top end of the inner wall of the outer shell 1. Chamber 9 is in an inverted trapezoidal shape and has a downward opening. The interior of Chamber 9 is connected in a through manner with the interior of the climbing plate 7. Chamber 9 is connected to the first air extraction pump 8. The flow guiding plate 10 is fixedly arranged inside Chamber 9. The flow guiding plate 10 is inclined away from the climbing plate 7. An air flow channel 11 is arranged between the flow guiding plate 10 and the inner wall of Chamber 9. The width of the air flow channel 11 is greater than the width of the climbing plate 7. The air extraction pipe 12 is fixedly arranged on Chamber 9. One end of the air extraction pipe 12 is connected to the first air extraction pump 8.

[0040] The tea leaves entering Chamber 9 from the climbing plate 7 will slide downward along the inclined flow guiding plate 10 under the action of the air flow generated by the first air extraction pump 8. Since Chamber 9 is in an inverted trapezoidal shape and the width of the air flow channel 11 is greater than the width of the climbing plate 7, the flow rate of the air flow in Chamber 9 will gradually decrease, making the air flow lifting force received by the tea leaves during the falling process decrease. At this time, some tea leaves with slightly greater weight will first fall to the opening at the bottom of Chamber 9, while the tea leaves with lighter weight will continue to move towards the interior of the first air extraction pump 8 through the air extraction pipe 12 along with the air flow, thus achieving classification separation.

[0041] The third separation mechanism 6 includes: The hollow plate 13 is arranged inside the outer shell 1. The hollow plate 13 is in a "冂" shape. The side of the hollow plate 13 close to Chamber 9 has a downward opening. One end of the hollow plate 13 is connected to the lower end of Chamber 9. A separation pipe 26 is arranged on the side of the hollow plate 13 far from Chamber 9. The separation pipe 26 is connected through the outer shell 1. The separation chamber 14 is arranged outside the outer shell 1. The separation chamber 14 is fixedly connected to the separation pipe 26. The separation chamber 14 has a downward opening. The second air extraction pump 15 is arranged on one side of the separation chamber 14. The second air extraction pump 15 is connected to one side of the separation chamber 14.

[0042] When the heavier tea leaves leave chamber 9 and enter below the hollow plate 13, the second suction pump 15 starts working, evacuating air from inside the hollow plate 13 through the separation pipe 26. Guided by the airflow, the tea leaves move along the "U" path of the hollow plate 13. The heavier tea leaves are discharged from the opening of the hollow plate 13, while the relatively lighter tea leaves enter the separation chamber 14 for further separation. The finished tea leaves fall into the opening of the separation chamber 14, while the lighter ones enter the second suction pump 15. Through this design, tea leaves that still do not meet the requirements after the second separation can be screened again, further recovering any usable tea leaves that may exist, reducing raw material waste, and improving the overall separation effect.

[0043] An inclined plate 16 is fixedly installed on the inner wall of the separation chamber 14.

[0044] When the tea leaves enter the separation chamber 14, the inclined plate 16 guides them, allowing tea impurities to slide down along the inclined direction under the combined action of their own gravity and airflow. This prolongs the residence time of tea impurities in the separation chamber 14, giving the second air pump 15 more time to separate impurities of different weights. At the same time, the inclined design also prevents tea impurities from accumulating on the inner wall of the separation chamber 14, ensuring a smooth separation process.

[0045] The separation device 3 is equipped with a collection mechanism 17, which is used to separate the tea leaves after separation.

[0046] The collection mechanism 17 includes: The first collection component 18 is disposed below the climbing plate 7 and is connected through the outer shell 1. The first collection component 18 is used to collect tea leaves that do not meet the requirements after the initial separation. The second collection component 19 is disposed below the first air pump 8 and the second air pump 15, and is used to collect the finished tea leaves from the second separation mechanism. Collection box 20 is located below separation chamber 14 and is used to collect finished tea leaves that meet the requirements.

[0047] The first collection component 18 and the second collection component 19 are conveyor belts. Tea leaves fall from the opening of the lifting plate 7 onto the conveyor belt of the first collection component 18 and are transported to the collection area outside the outer casing 1. The second collection component 19 is used to receive tea leaves separated from the first vacuum pump 8 and the second vacuum pump 15. The collected tea leaves are conveyed into the collection box 20 by the second collection component 19. The collection box 20 is placed directly below the separation chamber 14. Tea leaves that meet the requirements discharged from the opening of the separation chamber 14 fall naturally into the collection box 20 under the action of gravity, realizing the classification and collection of different separation results, avoiding the mixing of tea leaves, and facilitating the subsequent separate processing of various types of tea leaves.

[0048] The separation device 3 is equipped with a windproof mechanism 21, which is used to seal the chamber 9 and the separation chamber 14.

[0049] The windbreak mechanism 21 can effectively prevent external airflow from entering the chamber 9 and the separation chamber 14, thereby ensuring the stability of airflow velocity and pressure during the tea separation process and further improving the accuracy and reliability of the separation.

[0050] The windbreak mechanism 21 includes: The first wind-blocking shaft 22 is rotatably disposed at the bottom of the chamber 9. The first wind-blocking shaft 22 is provided with a plurality of wind-blocking blocks 23 along the circumferential direction. The wind-blocking blocks 23 are in contact with the interior of the chamber 9. The second windshield shaft 24 is rotatably disposed at the bottom of the separation chamber 14. The second windshield shaft 24 is provided with a plurality of windshield plates 25 along the circumferential direction, and the windshield plates 25 are in contact with the interior of the separation chamber 14.

[0051] When the tea leaves are discharged from the bottom opening of the chamber 9, they will come into contact with the baffle block 23 on the first baffle shaft 22, pushing the baffle block 23 to drive the first baffle shaft 22 to rotate. At this time, the baffle block 23 rotates with the shaft to open the opening. Similarly, when the tea leaves and impurities are discharged, the baffle plate 25 at the bottom of the separation chamber 14 is impacted and rotates to open the channel. This structure can ensure that the tea leaves are discharged smoothly, and can also minimize the leakage of airflow in the chamber 9 and the separation chamber 14, maintain the stability of the internal airflow environment, and ensure the continuous and efficient operation of the separation.

[0052] A separation device 3 for tea refining and a separation method thereof, based on the above-described separation device 3 for tea refining, includes a separation method comprising the following steps: S1. Tea feeding: Tea leaves enter the interior of the outer shell 1 through the feed port of the outer shell 1 and are conveyed to the separation device 3 by the conveying device 2; S2, Tea Leaf Separation: The conveying device 2 transports the tea leaves to the climbing plate 7 of the first separation mechanism 4. The first air pump 8 operates to generate an upward airflow. Lighter tea leaves are sucked into the climbing plate 7 and conveyed to the second separation mechanism 5. The tea leaves entering the chamber 9 of the second separation mechanism 5 are guided by the guide plate 10 and the airflow. The heavier tea leaves fall into the bottom opening of the chamber 9, while the lighter tea leaves enter the second collection component 19 with the airflow. Tea leaves that do not meet the requirements after the second separation enter the third separation mechanism 6. In the third separation mechanism 6, the second air pump 15 draws air through the separation pipe 26, causing the tea leaves to move along the hollow plate 13. The heavier tea leaves are discharged from the opening of the hollow plate 13, while the lighter tea leaves enter the separation chamber 14. After being guided by the inclined plate 16, the tea leaves fall into the collection box 20.

[0053] S3, Tea Collection: Tea leaves that do not meet the requirements in the first separation mechanism 4 slide down the climbing plate 7 to the first collection component 18 and leave the inside of the outer shell 1. Lighter tea leaves in the second separation mechanism 5 and the third separation mechanism 6 are carried by the airflow through the exhaust pipe 12 into the second collection component 19. The collected tea leaves are conveyed by the second collection component 19 into the collection box 20. Tea leaves that meet the requirements in the separation chamber 14 fall into the collection box 20.
