Description

Technical Field

[0001] This utility model relates to a sieving and air-separating device, and more particularly to a tea sieving and air-separating device. Background Technology

[0002] During tea processing, a tea air separator is used to separate light particles, tea dregs, or sand and gravel from the tea leaves using air power. The air separator can effectively recover the first leaves and the last leaves of light particles, which can reduce tea loss and ensure the safety of tea processing.

[0003] However, existing tea air separators often fail to effectively distinguish between tea leaves and impurities, tea leaves and tea stems, and tea leaves and broken tea leaves due to the relatively blurred specific gravity boundaries. This results in unsatisfactory screening results. Utility Model Content

[0004] The purpose of this utility model is to provide a tea sieving and air-separating device to solve the problem that existing tea air-separating machines often cannot effectively distinguish between tea leaves and impurities, tea leaves and tea stems, and tea leaves and broken tea leaves due to the relatively blurred specific gravity boundaries. This results in unsatisfactory sieving effects.

[0005] To address the aforementioned problems, this utility model provides a tea sieving and air-separating device, comprising an air-separating box, a feed inlet at the top of the air-separating box, an inclined vibrating plate inside the air-separating box with its upper end extending beyond the feed inlet, ventilation holes on the vibrating plate inside the air-separating box, a supply hood perpendicular to the vibrating plate fixedly connected to the air-separating box below the vibrating plate, a collecting hood corresponding to the supply hood on the vibrating plate, an air duct fixedly connected to the upper end of the collecting hood, the other end of the air duct fixedly connected to the air-separating box and having an air vent at the end of the air duct, multiple discharge ports below the air duct, and a pull-out storage bin below the discharge ports, with multiple compartments along the air duct inside the storage bin.

[0006] The tea sieving and air-separating device provided by this utility model also has the following technical features: Furthermore, a guide vane inclined towards the vent is provided between adjacent discharge ports.

[0007] Furthermore, there are at least two sets of air supply hoods and air collection hoods along the length of the vibrating plate, and the air classifier is fixedly connected to a fan at the position of the air supply hood. The air supply volume of the fan along the length of the vibrating plate gradually increases from top to bottom.

[0008] Furthermore, an inclined baffle is fixedly connected to the discharge port, and the baffle is aligned with the transverse direction of the vibrating plate.

[0009] Furthermore, load-bearing plates are fixedly connected to both ends of the vibrating plate, and springs are fixedly connected between the load-bearing plates and the air separator.

[0010] Furthermore, a vibration motor is fixedly connected to the vibration plate.

[0011] Furthermore, a pull-out slag storage box is provided at the bottom of the vibrating plate.

[0012] The present invention has the following beneficial effects: The tea sieving and air-sorting device described in this application uses a vibrating plate to continuously lift the tea leaves. At the same time, the different specific gravities of tea leaves, tea stems, and impurities are carried by the wind to different distances during air sorting and fall into different compartments, thus dividing the tea leaves into different grades and separating the impurities, thereby improving the accuracy and effect of sieving.

[0015] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0016] like Figures 1 to 3 In the embodiment of the tea sieving and air-separating device of this utility model shown, the tea sieving and air-separating device includes an air-separating box 1, a feed inlet 2 at the top of the air-separating box 1, an inclined vibrating plate 3 inside the air-separating box 1, the upper end of the vibrating plate 3 extending out of the feed inlet 2, a ventilation hole 4 on the vibrating plate 3 inside the air-separating box 1, an air supply hood 5 perpendicular to the vibrating plate 3 fixedly connected to the air-separating box 1 below the vibrating plate 3, an air collecting hood 6 corresponding to the air supply hood 5 on the vibrating plate 3, an air duct 7 fixedly connected to the upper end of the air collecting hood 6, the other end of the air duct 7 fixedly connected to the air-separating box 1, and an air vent 8 at the end of the air duct 7 on the air-separating box 1, a plurality of discharge ports 9 below the air duct 7, a pull-out storage bin 10 below the discharge port 9, and a plurality of compartments 11 along the air duct inside the storage bin 10.

[0017] Specifically, the tea leaves to be screened and air-separated are fed onto the vibrating plate 3 through the feed inlet 2, causing the vibrating plate 3 to vibrate. As the tea leaves vibrate, they gradually move downwards along the vibrating plate 3. When they reach the position of the air supply hood 5, the air blown out by the air supply hood 5 blows the lighter broken tea leaves, tea leaves, and small buds into the air collection hood 6 through the air vent 7 and moves towards the air outlet 8. As the wind force decreases due to the extended distance, the heavier tea leaves, buds, and broken tea leaves gradually fall into the compartment 11 below the discharge port 9. Impurities that cannot be blown into the air collection hood 6 fall down the vibrating plate 3 to the bottom of the air separation box 1.

[0018] In one embodiment of this application, preferably, a guide plate 12 inclined towards the vent hole 8 is provided between adjacent discharge ports 9 to prevent the wind from disturbing the tea leaves that have fallen into the storage compartment 11, and at the same time to reduce the wind force so that the heavier tea leaves can fall as quickly as possible, and to prevent backflow at the vent hole 8 when the wind force is too strong.

[0019] In one embodiment of this application, preferably, there are at least two sets of air supply hood 5 and air collection hood 6 along the length of the vibrating plate 3. The air classifier 1 is fixedly connected to the air supply hood 5. The air supply volume of the air fan 13 along the length of the vibrating plate 3 gradually increases from top to bottom for multi-stage screening. Under the action of the upper air fan 13, the tea leaves that have not entered the air duct 7 fall from the air collection hood 6 into the vibrating plate 3 and continue to move downwards, and are swept into the air duct 7 by a greater wind force, increasing the number of screening levels.

[0020] In one embodiment of this application, preferably, an inclined baffle 14 is fixedly connected to the discharge port 9. The baffle 14 is aligned with the transverse direction of the vibrating plate 3 to slow down the speed at which the tea leaves enter the air separator 1 and prevent the tea leaves from tangling together and being unable to be dispersed by the wind.

[0021] In one embodiment of this application, preferably, a load-bearing plate 15 is fixedly connected to both ends of the vibrating plate 3, and a spring 16 is fixedly connected between the load-bearing plate 15 and the air separator 1 to make the vibrating plate 3 vibrate, so that the tea leaves vibrate more dispersedly on the vibrating plate 3 and are easily blown up by the wind.

[0022] In one embodiment of this application, preferably, a vibration motor 17 is fixedly connected to the vibration plate 3 for driving the vibration plate 3 to vibrate.

[0023] In one embodiment of this application, preferably, the bottom end of the vibrating plate 3 is provided with a pull-out slag storage box 18 for collecting the impurities remaining on the vibrating plate 3 after wind separation.

[0024] In summary, the tea sieving and air-separating device in the above embodiments of this utility model specifically involves feeding the tea leaves to be sieved and air-separated onto the vibrating plate 3 through the feed inlet 2, causing the vibrating plate 3 to vibrate. As the tea leaves vibrate, they gradually move downwards along the vibrating plate 3. When they reach the position of the air supply hood 5, the air blown out by the air supply hood 5 blows the lighter broken tea leaves, tea leaves, and small buds into the air collection hood 6 through the ventilation holes 4, and then moves towards the exhaust hole 8 through the air duct 7. As the wind force decreases due to the extended distance, the heavier tea leaves, buds, and broken tea leaves gradually fall into the bin 11 below the discharge port 9. Impurities that cannot be blown into the air collection hood 6 continue to move downwards along the vibrating plate 3. The air blown out by the air supply hood 5, which has a larger air volume, blows the tea leaves into the lower air duct 7 and into the bin 11 of the storage bin 10. Finally, the impurities fall into the slag storage box 18 on the vibrating plate 3.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
