Description

Technical Field

[0001] The invention relates to the field of tea leaf air separation, and in particular to a reciprocating and turbulent fresh tea leaf air separation machine. Background Art

[0002] During the tea production process, fresh tea leaves need to be screened and graded. Generally, they are classified according to the degree of wholeness of the leaves of the same type. The whole leaves have the largest mass, and the tea leaves have the smallest mass. In this process, a tea air sorter is usually used for sorting, and wind power is used to screen tea leaves of different qualities.

[0003] A common tea air separation machine consists of an air separation box, a feeding structure, a blower and a discharge port. The tea leaves fall into the air separation box through the feeding structure. During the falling process, the wind force of the blower is used to air separate the tea leaves. Whole and heavier tea leaves fall down, and the tea leaves are blown to the tail end of the air separation box by the wind before falling down. The remaining tea leaves fall at different positions in the middle according to the weight of the leaves. At the same time, the falling tea leaves are collected through the discharge port set at the bottom of the air separation box, thus completing the tea air separation process.

[0004] Existing tea air sorting machines usually feed tea continuously during feeding. Heavier tea leaves are easily mixed with lighter tea leaves to form a tea pile. A small amount of lighter tea leaves are discharged with the tea pile before being blown up, resulting in poor tea air sorting effect. Summary of the Invention

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention provides a reciprocating and bumping fresh tea leaf air separator, comprising an air separator housing 1, wherein a vertical compartment 2 and a horizontal compartment 3 connected to each other are formed in the air separator housing 1, a material inlet 4 is provided on the side wall of the vertical compartment 2, a centrifugal fan is provided at the bottom of the vertical compartment 2, and a discharge port group 5 is provided at the bottom of each of the vertical compartment 2 and the horizontal compartment 3;

[0050] A cylindrical cavity 6 is formed in the vertical cabin 2 along the horizontal direction. The cylindrical cavity 6 is open at the top and bottom. A wind balancing plate group 7 is rotatably installed in the cylindrical cavity 6. The end of the wind balancing plate group 7 is connected to a movable driving structure 8, which drives the wind balancing plate group 7 to rotate back and forth.

[0051] The wind balancing plate group 7 is densely covered with small holes, which evenly distribute the air volume in the vertical cabin 2 to achieve wind uniformity control. An arc-shaped guide wall 16 is formed on the inner wall of the top corner of the vertical cabin 2 facing the wind balancing plate to guide the vertical wind into horizontal wind.

[0052] The wind flowing in the horizontal cabin 3 needs to be discharged outside the horizontal cabin 3. Specifically, an air release plate 17 is installed on the wall of the horizontal cabin 3 close to the discharge port group 5. The wind flowing in the horizontal cabin 3 can be discharged directly from the air release plate 17, wherein the air release plate 17 is also densely covered with small holes.

[0053] In the present invention, a discharge port group 5 is provided at the bottom of the vertical cabin 2 and the horizontal cabin 3. The wind generated by the fan flows upward along the vertical cabin 2 and blows part of the lighter fresh tea leaves input from the leaf inlet into the horizontal cabin 3 and then discharged from the discharge port group 5. The remaining heavier fresh tea leaves slide along the wind equalizing plate to the discharge port group 5 for discharge.

[0054] Specifically, if Figure 2 As shown, the discharge port group 5 includes a first discharge port 51 provided at the bottom of the vertical compartment 2, a second discharge port 52 and a third discharge port 53 provided at the bottom of the horizontal compartment 3, and a first partition 18 is provided between the vertical compartment 2 and the horizontal compartment 3. The first partition 18 does not completely close the passage between the vertical compartment 2 and the horizontal compartment 3;

[0055] A second partition 19 is provided in the horizontal compartment 3 , and the second partition 19 is located between the second discharge port 52 and the third discharge port 53 . The first partition 18 can separate the first discharge port 51 from the second discharge port 52 , and the second partition 19 can separate the second discharge port 52 from the third discharge port 53 .

[0056] After the fresh tea leaves enter the vertical compartment 2, they fall downward under the action of gravity. The vertical upward wind generated by the fan flows upward along the vertical compartment 2. Some of the heavier fresh tea leaves are not blown up, and some of the lighter fresh tea leaves are blown up by the wind and carried upward to the horizontal compartment 3. After being blown horizontally by the wind, the fresh tea leaves with uniform weight are discharged from the second discharge port 52, and the lightest fresh tea leaves are discharged from the third discharge port 53. The wind is discharged from the air release plate 17.

[0057] In order to balance the pressure and prevent a large amount of fresh tea leaves entering the horizontal compartment 3 from entering the third discharge port 53 , an air release plate 17 may also be provided on the top of the horizontal compartment 3 .

[0058] In the present invention, the air balancing plate group 7 can move back and forth, and the angle of the air balancing plate group 7 rotating back and forth gradually increases. When the air balancing plate group 7 rotates to face the discharge port group 5, one end of the air balancing plate group 7 detaches from the cylindrical cavity 6 to form a through opening 9 between the air balancing plate group 7 and the cylindrical cavity 6.

[0059] The wind generated by the centrifugal fan flows upward along the vertical cabin 2 and blows part of the fresh tea leaves put into the cylindrical cavity 6 from the feed port 4 into the horizontal cabin 3 and then discharged from the discharge port group 5. The remaining fresh tea leaves fall onto the air distribution plate group 7 and are tossed back and forth and dispersed as the air distribution plate group 7 rotates back and forth. In the process of tossing back and forth, a part of the fresh tea leaves on the air distribution plate group 7 are blown upward under the action of wind, and the other part slides along the air distribution plate group 7 to the discharge port group 5 when the through-hole 9 is opened and is discharged.

[0060] In the present invention, the fresh tea leaves that fall onto the air balancing plate group 7 are repeatedly shaken as the air balancing plate group 7 rotates, and the wind force is used to disperse the pile of fresh tea leaves, avoiding the situation where a small amount of lighter tea leaves are mixed into heavier tea leaves and are discharged, thereby ensuring the air selection effect of the tea leaves.

[0061] In addition, by rotating the air balancing plate group 7 back and forth, the fresh tea leaves constantly change their state during the back and forth rotation and shaking, the entanglement state between the fresh tea leaves is adjusted, the probability of air separation of lighter tea leaves is increased, and the air separation time of the entire batch of fresh tea leaves is extended. After several rounds of back and forth air separation, the lighter tea leaves are basically completely blown up, which optimizes the tea air separation effect.

[0062] In the present invention, the cylindrical cavity 6 is mainly used to provide a place for the air distribution plate group 7 to move, and the air distribution plate group 7 is limited to a specific range for rotational movement. Specifically, Figure 4 and Figure 5 As shown, the inner walls on both sides of the vertical cabin 2 are respectively provided with a first slot seat 10 and a second slot seat 11. The inner walls of the first slot seat 10 and the second slot seat 11 are both formed with arc-shaped slot walls. A cylindrical cavity 6 is formed between the first slot seat 10 and the second slot seat 11, and the wind plate group 7 is in sliding contact with the inner walls of the first slot seat 10 and the second slot seat 11.

[0063] Among them, a first inclined side wall 12 is formed on the top of the first groove seat 10, facing the feed port 4, and a second inclined side wall 13 is formed at the bottom of the second groove seat 11, facing the discharge port group 5. After the fresh tea leaves are put into the feed port 4, they pass through the first inclined side wall 12 and enter the air distribution plate group 7 in the cylindrical cavity 6. The second inclined side wall 13 is designed to avoid obstruction during the discharge of the fresh tea leaves.

[0064] In order not to affect the vertical flow of wind, vertical air holes 15 are densely distributed on the first slot seat 10 and the second slot seat 11, and wind can flow upward through the air holes 15.

[0065] The wind plate group 7 can rotate back and forth under the drive of the movable driving structure 8, and when the rotation angle reaches a certain value, the end of the wind plate group 7 can form a through hole 9, specifically, as shown in FIG. Figure 6As shown, the air distribution plate group 7 includes a first plate body 71 and a second plate body 72. The second plate body 72 is arranged at the bottom of the first plate body 71. The edge of the first plate body 71 is in sliding contact with the groove wall of the first groove seat 10, and the second plate body 72 is in sliding contact with the groove wall of the second groove seat 11.

[0066] The edge of the first plate 71 is away from the groove wall of the second groove seat 11 , the length of the second plate 72 is half of the length of the first plate 71 , and a plate flange 73 is formed thereon, which is arranged between the first plate 71 and the second groove seat 11 .

[0067] The air equalizing plate group 7 is set to a structure of a first plate body 71 and a second plate body 72, so that when the first plate body 71 and the second plate body 72 are rotated to a specific angle, the second plate body 72 can be separated from the first plate body 71, and the plate flange 73 is away from the first plate body 71. At this time, the first plate body 71 and the second plate body 72 are disassembled, and the fresh tea leaves can slide off from the end of the first plate body 71.

[0068] Among them, setting the length of the second plate body 72 to half of the first plate body 71 is also to avoid the first plate body 71 blocking half of the second plate body 72 when the second plate body 72 rotates away from the first plate body 71. By setting the length of the second plate body 72 to be half, the second plate body 72 can rotate freely in the clockwise direction away from the first plate body 71 without being blocked.

[0069] Furthermore, in order to prevent the first plate 71 from excessively rotating and separating from the first groove seat 10, causing part of the fresh tea leaves to enter the bottom of the first plate 71 and the second plate 72, the present invention makes the following design, such as Figure 4 As shown, a limiting pin 14 is provided at the opening of the first slot seat 10 . The limiting pin 14 will not block the loading of fresh tea leaves and can limit the movement of the first plate body 71 .

[0070] Among them, such as Figure 4 、 5 As shown, when the first plate body 71 rotates clockwise to the limit pin 14 and cannot continue to rotate, the second plate body 72 continues to rotate under the drive of the movable driving structure 8 and disengages from the second groove seat 11 to form a through-hole 9 between the second groove seat 11 and the second plate body 72. At this time, the fresh tea leaves can slide along the first plate body 71 to the second plate body 72 and then enter the first discharge port 51 from the through-hole 9.

[0071] In order to prevent the fresh tea leaves from falling into the bottom of the vertical chamber 2 between the through hole 9 and the first discharge port 51 during the sliding process, a specific guide plate can also be set in the first discharge port 51 to connect the through hole 9 and the first discharge port 51.

[0072] In the present invention, the second plate body 72 serves as a rotating body, which can drive the first plate body 71 to rotate. In order to ensure the driving performance of the back-and-forth rotation, the present invention makes the following design: a magnetic sheet 74 is embedded in the second plate body 72 to form a magnetic attraction on the first plate body 71. Under the action of the magnetic attraction, the first plate body 71 can be driven to rotate together during the clockwise or counterclockwise rotation of the second plate body 72.

[0073] Among them, the first plate body 71 is installed on the inner wall of the vertical cabin 2 through an axial movement, and the side of the second plate body 72 is connected to the movable driving structure 8. The first plate body 71 and the second plate body 72 are on the same straight line around the center axis of rotation. If the rotation center axes of the first plate body 71 and the second plate body 72 are not on the same straight line, then when the second plate body 72 rotates clockwise away from the first plate body 71, it is necessary to consider the possible interference problem at the rotation center axis. Such a design can further avoid the first plate body 71 from blocking the relative rotation movement of the second plate body 72.

[0074] The present invention can drive the second plate 72 to rotate through the movable driving structure 8. Specifically, Figure 7 、 Figure 8 and Figure 9 As shown, the movable driving structure 8 includes a connecting shaft 81 connected to the side of the second plate 72 and a sleeve 82 connected to the end of the connecting shaft 81;

[0075] The connecting shaft 81 passes through the side wall of the vertical chamber 2. An installation chamber 83 is provided outside the air separation housing 1. A limiting column 84 is provided in the installation chamber 83. The sleeve 82 is rotatably mounted on the limiting column 84.

[0076] A lifting frame 85 is provided in the installation chamber 83. A hydraulic cylinder 86 is connected to the top of the lifting frame 85. The lifting frame 85 is provided outside the sleeve 82. A shifting rod 87 is connected to the outside of the sleeve 82. A first shifting block 88 and a second shifting block 89 are connected to the upper and lower positions of the lifting frame 85 corresponding to the shifting rod 87, respectively.

[0077] The hydraulic cylinder 86 drives the lifting frame 85 to move up and down. After the first toggle block 88 descends to abut against the toggle rod 87, the toggle rod 87 drives the sleeve 82 to rotate clockwise. After the second toggle block 89 rises to abut against the toggle rod 87, the toggle rod 87 drives the sleeve 82 to rotate counterclockwise.

[0078] In the above embodiment, the hydraulic cylinder 86 drives the lifting frame 85 to rise and fall. After the first toggle block 88 drops to abut against the toggle rod 87, the first toggle block 88 continues to move downward and drives the sleeve 82 to rotate clockwise through the toggle rod 87. After the second toggle block 89 rises to abut against the toggle rod 87, the second toggle block 89 continues to move upward and drives the sleeve 82 to rotate counterclockwise through the toggle rod 87. The rotation of the sleeve 82 can drive the second plate 72 to rotate through the connecting shaft 81. The height of the lifting frame 85 can determine the rotation angle of the sleeve 82. Adjusting the height of each lifting of the lifting frame 85 can increase the rotation angle of the second plate 72 during the rotation process. In actual application, the height of the lifting frame 85 can be adjusted by adjusting the single liquid inlet amount inside the hydraulic cylinder 86.

[0079] The first and second plates 71 and 72 are in a state of being moved in a clockwise direction, so that the tea leaves fall on the first plate 71 and then rotate in the opposite direction, instead of the second plate 72 rotating in the opposite direction immediately and hitting the tea leaves that may still be in the air, thereby reducing damage to the tea leaves.

[0080] In the above process, the faster running speed of the first plate 71 and the second plate 72 can not only make part of the tea pile suspended in the air, accelerate the dispersion of fresh tea leaves, but also speed up the entire air selection speed and improve efficiency.

[0081] If the rotation speed of the first plate 71 and the second plate 72 is low, there is no need to move the first toggle block 88 and the second toggle block 89 away from the toggle rod 87. Accordingly, the first plate 71 and the second plate 72 rotate counterclockwise immediately after rotating clockwise. In this case, the tea leaves usually slide back and forth on the surface of the first plate 71. In this regard, in the process of gradual rotation and tilting of the first plate 71, heavier tea leaves are more likely to slide on the first plate 71, and lighter tea leaves will not slide until the first plate 71 rotates a certain angle. The same is true between piles of heavier or lighter tea leaves. In the process of gradually changing the tilting angle, the dispersion between the tea leaves or between the tea leaf piles is also accelerated, making the lighter tea leaves inside the tea leaf piles easier to be blown up.

[0082] In the present invention, the sleeve 82 will not move without external force. For this reason, a friction pad is provided between the sleeve 82 and the limiting column 84. The limiting column 84 is fixed. The design of the friction pad is such that a large friction force is formed between the sleeve 82 and the limiting column 84. The sleeve 82 can only rotate when it is subjected to a certain external force. It will not rotate when there is no external force or very small external force.

[0083] In summary, the main implementation process of the present invention is:

[0084] After the fresh tea leaves enter the vertical compartment 2, they fall downward under the action of gravity and enter the cylindrical cavity 6. The vertical upward wind generated by the fan flows upward along the vertical compartment 2. Some heavier fresh tea leaves are not blown up, while some lighter fresh tea leaves are blown up and carried upward to the horizontal compartment 3. After being blown horizontally by the wind, the fresh tea leaves with uniform weight are discharged from the second discharge port 52, and the lightest fresh tea leaves are discharged from the third discharge port 53. The wind is discharged from the air release plate 17.

[0085] Some of the heavier fresh tea leaves and a small amount of lighter fresh tea leaves mixed in fall onto the air distribution plate group 7 and are tossed back and forth and dispersed as the air distribution plate group 7 rotates back and forth. During the tossing process, some of the lighter fresh tea leaves on the air distribution plate group 7 are blown upwards by the wind.

[0086] When the first plate 71 and the second plate 72 rotate back and forth to a certain angle, the first plate 71 cannot continue to rotate when it rotates clockwise to the limit pin 14, and the second plate 72 continues to rotate under the drive of the movable driving structure 8 and disengages from the second groove seat 11, forming a through-hole 9 between the second groove seat 11 and the second plate 72. At this time, another part of the heavier fresh tea leaves can slide along the first plate 71 to the second plate 72, and then enter the first discharge port 51 from the through-hole 9 and be discharged.

[0087] The above embodiments are merely exemplary embodiments of the present application and are not intended to limit the scope of the present application. The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
