Description

Technical Field

[0001] The utility model belongs to the technical field of tea processing, in particular to an air separation and dust removal device for tea processing. Background Technique

[0002] During the process of tea processing, in order to ensure the quality of the tea after packaging, it is necessary to remove dust from the tea, and most of them use the air separation method for dust removal. However, when removing dust from the tea by air separation, in most cases, a relatively large amount of tea is put in at one time, and the feeding of the tea is too concentrated, making it easy for the tea to accumulate together. When multiple intertwined teas fall, due to their large weight, the falling speed is fast, resulting in the blown air being difficult to penetrate through multiple intertwined teas, so that there will still be some dust inside the tea after air separation, thus reducing the quality of air separation and dust removal of the tea.

[0003] For example, the existing Chinese publication number is: CN207996812U, a tea air separator, which: "comprises a frame, an air separation chamber, a controller, a motor, a fan, a tea inlet hopper, a tea outlet hopper, a dust removal chamber and a wind speed sensor. The frame is provided with an air separation chamber, the tea inlet hopper is arranged above the air separation chamber, the lower end of the tea inlet hopper is inclined, and several tea outlet hoppers are arranged below the air separation chamber."

[0004] It can be seen that the cited patent document has the problem that the tea is easy to accumulate and difficult to remove dust. Content of the Utility Model

[0005] The purpose of the utility model is to provide an air separation and dust removal device for tea processing to solve the problems put forward in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an air separation and dust removal device for tea processing, comprising a box body. The upper half of one side of the box body is provided with a feeding groove. The inner side wall of the feeding groove is fixedly provided with an inclined plate for conveying tea. The part of the inclined plate located in the inner cavity of the box body is inclined downward. The upper half of the inner side wall of the box body is fixedly provided with an electric push rod. The output end of the electric push rod is horizontally fixedly provided with a cross plate. One side surface of the cross plate is fixedly provided with an inverted L-shaped connecting frame. The inner side wall of the box body and on one side of the electric push rod is rotatably connected with a bidirectional threaded rod. One side surface of the cross plate extends to the periphery of the bidirectional threaded rod and is threadedly connected therewith. A vertical rod is threadedly sleeved on the periphery of the bidirectional threaded rod. The bottom end of the vertical rod and the end of the connecting frame far from the cross plate are both fixedly provided with a push plate for dispersing tea.

[0007] Preferably, one end of the bidirectional threaded rod far from the inner side wall of the box body is rotatably connected with a fixing plate, and the top surface of the fixing plate is fixedly arranged on the inner top surface of the box body.

[0008] Preferably, a limiting rod is transversely fixed on one side of the fixing plate and above the bidirectional threaded rod, and the vertical rod is slidably sleeved on the periphery of the limiting rod.

[0009] Preferably, limiting plates for restricting tea leaves are symmetrically installed on both sides of the top surface of the inclined plate, and a hair dryer is bolted to the inner side wall of the box body and below the inclined plate.

[0010] Preferably, a through groove for the tea leaves to pass through is formed on one side of the inner bottom surface of the box body, and a collection box for collecting tea leaves is placed directly below the through groove on the bottom surface of the box body.

[0011] Preferably, a guiding plate is fixedly installed on the inner side wall of the box body, and an ash collection box is placed directly below the guiding plate on the inner bottom surface of the box body.

[0012] Preferably, both of the push plates are inclined at the same angle as the inclined plate, and both of the push plates are arranged above the inclined plate.

[0013] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0014] In this tea processing air separation and dust removal device, through the arrangement of the electric push rod and the cross plate, the connecting frame and the push plate can be driven to move. When the cross plate moves, it will drive the bidirectional threaded rod to rotate. And in cooperation with the rotation of the bidirectional threaded rod, the other push plate can be driven to move through the vertical rod, so that the two push plates can move in opposite or relative directions above the inclined plate, enabling the two push plates to push and disperse the accumulated tea leaves, allowing the tea leaves to be separated for air separation, avoiding the situation that the blown air is difficult to penetrate the accumulated tea leaves due to the relatively fast falling speed of the accumulated tea leaves, and thus there is still some dust inside the tea leaves, improving the quality of air separation and dust removal of the tea leaves.

[0015] Through the arrangement of the limiting plate, the position of the tea leaves on the surface of the inclined plate can be limited, and through the arrangement of the limiting rod, the movement of the vertical rod can be limited. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0024] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figures shown in the present utility model, and are hereby explained together.

[0025] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., according to actual needs.

[0026] As Figures 1 to 4 shown, a pneumatic selection and dust removal device for tea processing includes a box body 1. A support leg is installed on one side surface of the box body 1 to support the box body 1. The upper half of one side surface of the box body 1 is provided with a feeding trough 2. The inner side wall of the feeding trough 2 is fixedly provided with an inclined plate 3 for conveying tea. The part of the inclined plate 3 located inside the box body 1 is arranged obliquely downward, and one side surface of the inclined plate 3 extends to one side of the box body 1, so that the staff can put the tea to be dust-removed on the inclined plate 3 and move it to the inside of the box body 1 through the inclined surface of the inclined plate 3 for dust removal. Limit plates 17 for restricting tea are symmetrically installed on both sides of the top surface of the inclined plate 3. The limit plates 17 can limit the tea on the top surface of the inclined plate 3 to prevent the tea from falling off the top surface of the inclined plate 3 when moving.

[0027] On the upper half of the inner side wall of the box body 1, an electric push rod 4 is fixedly installed. The electric push rod 4 is arranged above the inclined plate 3. A transverse plate 5 is fixedly installed horizontally at the output end of the electric push rod 4. An inverted L-shaped connecting frame 6 is fixedly installed on one side surface of the transverse plate 5. A bidirectional threaded rod 7 is rotatably connected to the inner side wall of the box body 1 and located on one side of the electric push rod 4. One side surface of the transverse plate 5 extends to the periphery of the bidirectional threaded rod 7 and is threadedly connected thereto. When the electric push rod 4 drives the transverse plate 5 to move, the transverse plate 5 can drive the connecting frame 6 to move. At the same time, the transverse plate 5 will move on the periphery of the bidirectional threaded rod 7. Since the transverse plate 5 is threadedly connected to the bidirectional threaded rod 7, and one end of the bidirectional threaded rod 7 is rotatably connected to the inner side wall of the box body 1, when the transverse plate 5 moves on the periphery of the bidirectional threaded rod 7, it will drive the bidirectional threaded rod 7 to rotate, and cooperate with the electric push rod 4 to drive the transverse plate 5 to perform a reciprocating motion, thereby driving the bidirectional threaded rod 7 to rotate forward and backward.

[0028] A vertical rod 8 is threadedly sleeved on the periphery of the bidirectional threaded rod 7. At the bottom end of the vertical rod 8 and at one end of the connecting frame 6 away from the transverse plate 5, a push plate 9 for dispersing tea leaves is fixedly installed. When the bidirectional threaded rod 7 rotates, it will drive the vertical rod 8 to move. Due to the arrangement of two threads with opposite directions on the periphery of the bidirectional threaded rod 7, the vertical rod 8 and the connecting frame 6 will move in opposite or relative directions, so that the two push plates 9 will move in opposite or relative directions. Both of the two push plates 9 are inclined at the same angle as the inclined plate 3. Both of the two push plates 9 are arranged above the inclined plate 3, so that the two moving push plates 9 can push and disperse the tea leaves piled up on the surface of the inclined plate 3, and cooperate with the reciprocating motion of the electric push rod 4 to drive the transverse plate 5, so that the two push plates 9 can continuously push and disperse the tea leaves, enabling the tea leaves to fall downward in a dispersed state for air separation and dust removal, avoiding the situation that the blown air is difficult to penetrate the piled-up tea leaves due to the relatively fast falling speed of the piled-up tea leaves, and there is still some dust inside the tea leaves, thus improving the quality of air separation and dust removal of the tea leaves.

[0029] One end of the bidirectional threaded rod 7 away from the inner side wall of the box body 1 is rotatably connected to a fixing plate 10. The top surface of the fixing plate 10 is fixedly installed on the inner top surface of the box body 1. A limiting rod 11 is fixedly installed horizontally on one side surface of the fixing plate 10 and above the bidirectional threaded rod 7. The vertical rod 8 is slidably sleeved on the periphery of the limiting rod 11. When the bidirectional threaded rod 7 drives the vertical rod 8 to perform a reciprocating motion, the vertical rod 8 will perform a reciprocating motion on the periphery of the limiting rod 11, and the limiting rod 11 limits the position of the vertical rod 8.

[0030] The inner side wall of the box body 1 and below the inclined plate 3 is bolted with a hair dryer 12. A through groove 13 for the tea leaves to pass through is formed on one side of the inner bottom surface of the box body 1. A collection box 14 for collecting tea leaves is placed directly below the through groove 13 on the bottom surface of the box body 1. A guiding plate 15 is fixedly installed on the inner side wall of the box body 1. An ash collection box 16 is placed directly below the guiding plate 15 on the inner bottom surface of the box body 1. After the dispersed tea leaves fall downward from one side of the inclined plate 3, the hair dryer 12 is turned on. The air blown by the hair dryer 12 can blow the lighter dust towards the guiding plate 15 and enter the ash collection box 16 along the guiding plate 15 for collection. The heavier tea leaves will fall downward and pass through the through groove 13, and then fall into the collection box 14 to collect the tea leaves after dust removal. One side surface of the box body 1 is connected with a box door through a hinge, and the box door can be opened to take out the ash collection box 16 from the box body 1 for processing.

[0031] Working principle:

[0032] For this air separation and dust removal device for tea processing, the tea leaves to be dust-removed are put on the surface of the inclined plate 3 and then enter the box body 1 along the inclined plate 3. At this time, the electric push rod 4 is turned on. The electric push rod 4 drives the connecting frame 6 and the push plate 9 to move through the cross plate 5, so that the push plate 9 can move above the inclined plate 3 to disperse the accumulated tea leaves. When the cross plate 5 moves, it will synchronously drive the bidirectional threaded rod 7 to rotate, so that the rotating bidirectional threaded rod 7 drives the vertical rod 8 to move, and then the vertical rod 8 drives the other push plate 9 to move. Due to the setting of the bidirectional threaded rod 7, the two push plates 9 move in opposite or relative directions, and cooperate with the electric push rod 4 to continuously drive the cross plate 5 to reciprocate, so as to drive the two push plates 9 to continuously disperse the tea leaves and keep the tea leaves in a dispersed state. After the dispersed tea leaves move to one side of the inclined plate 3 and fall downward, the hair dryer 12 is turned on, so that the hair dryer 12 blows the lighter dust towards the guiding plate 15 and enters the ash collection box 16 along the guiding plate 15, while the heavier tea leaves will pass through the through groove 13 and fall into the collection box 14 for collection, completing the air separation and dust removal of the tea leaves, avoiding the situation that the air blown out is difficult to penetrate the accumulated tea leaves due to the faster falling speed of the accumulated tea leaves, and there is still some dust inside the tea leaves, and improving the quality of air separation and dust removal of the tea leaves.
