Description

Technical Field

[0001] This utility model relates to a screening device, and more particularly to a screening device for processing thorn flower tea. Background Technology

[0002] Sieving is a crucial step in tea processing, effectively separating tea leaves with significant quality variations into different grades and categories of semi-finished products. For Qingci flower tea, sieving is particularly important because it helps to select tea raw materials that meet specific quality requirements, thus ensuring the stability and consistency of the final product. Fine sieving removes impurities and uneven portions, preserving high-quality tea leaves and improving the overall quality.

[0003] However, existing sieving technologies have some shortcomings in practical applications. Particularly during the drying process, the large accumulation of tea leaves during feeding can easily create sieving dead zones, preventing some scented teas from being effectively sieved. This accumulation not only affects the uniformity of sieving but may also cause some tea leaves to fail to meet the expected quality standards, thus reducing the quality and consistency of the final product. Utility Model Content

[0004] In order to overcome the shortcomings of existing technology, which has the disadvantage of creating screening dead zones due to excessive material accumulation during drying, and thus failing to screen the raw materials, the technical problem to be solved is to provide a screening device for processing thorn flower tea.

[0005] The technical solution of this utility model is: a sieving device for processing thorn flower tea, comprising a support frame, a sieving and drying drum, a first sieving screen, a feeding hopper, a first impeller, a partition screen, a mounting frame, a servo motor, a sieving plate, a second sieving screen, and a second impeller.

The discharge port of the feeding hopper contains a second impeller. The bottom of the sieving and drying drum has a first sieving screen. The front side of the sieving and drying drum is connected to the support frame. The device has a mounting frame containing a servo motor. The output shaft of the servo motor passes through the front end of the screening and drying drum. A first impeller is fixedly connected to the output shaft of the servo motor. The first impeller is rotatably installed inside the screening and drying drum. The first impeller has a total of eight blades, each with a screen. A discharge port is located on the lower left side of the screening and drying drum. A screening plate is slidably connected to the discharge port of the screening and drying drum. A second screening screen is located at the rear end of the screening plate, and a discharge chute is located at the front end of the screening plate. The first impeller and the second impeller are connected by a transmission component.

[0006] Optionally, the transmission component includes pulleys and a transmission belt, with pulleys connected to the rear ends of both the first impeller and the second impeller, and a transmission belt provided on the two pulleys.

[0007] Optionally, it also includes a pull-out frame and a storage compartment, with the pull-out frame slidably connected to the bottom of the bracket and the storage compartment slidably connected to the pull-out frame.

[0008] Optionally, the diameter of the second impeller is the same as the diameter of the discharge port of the hopper.

[0009] Optionally, an inclined block connected to the screening and drying drum is provided below the screening plate. The inclined block is used to guide the screened raw material of thorn flower tea into the storage compartment.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] A sieving device for processing thorn flower tea, such as Figures 1-5As shown, the device includes a support frame 1, a screening and drying drum 2, a first screening screen 3, a hopper 4, a first impeller 5, a partition screen 6, a mounting frame 7, a servo motor 8, a screening drawer plate 9, a second screening screen 11, a second impeller 12, a pulley 13, a drive belt 14, a pull-out frame 15, and storage compartments 16. The screening and drying drum 2 is connected to the support frame 1 and is vertically mounted on the support frame 1. The pull-out frame 15 is slidably connected to the bottom of the support frame 1. There are two pull-out frames 15, and each pull-out frame 15 has two storage compartments 16. The storage compartments 16 are slidably connected to the pull-out frame 15. The top of the screening and drying drum 2 is equipped with an inlet / outlet... The inlet of the screening and drying drum 2 is connected to the outlet of the hopper 4. A second impeller 12 with eight blades is located in the outlet of the hopper 4. The diameter of the second impeller 12 is the same as the diameter of the outlet of the hopper 4. The blades of the second impeller 12 contact the inner wall of the outlet of the hopper 4 when rotating. A first screening screen 3 is located at the bottom of the screening and drying drum 2. A mounting frame 7 is connected between the front side of the screening and drying drum 2 and the support 1. The mounting frame 7 is L-shaped and houses a servo motor 8. The output shaft of the servo motor 8 passes through the front end of the screening and drying drum 2. A first impeller 5 is fixedly connected to the top and is rotatably installed inside the screening and drying drum 2. The end of the first impeller 5 furthest from the center contacts the inner wall of the screening and drying drum 2. The first impeller 5 has a total of eight blades, and each blade of the first impeller 5 is equipped with a mesh 6. The gaps in the mesh 6 are not large enough to screen the raw materials of the green thorn flower tea, but only to make the hot air inside the screening and drying drum 2 more evenly distributed. The blades of the first impeller 5 and the mesh 6 are made of heat-resistant stainless steel. A discharge port is provided on the lower left side of the screening and drying drum 2. A screening guide plate 9 is slidably connected to the discharge port of the screening and drying drum 2. Below the screening guide plate 9 is a... The inclined block connected to the sieving drying drum 2 is used to guide the sieved green thorn flower tea raw material into the storage compartment 16. The sieving plate 9 has two openings. The rear end of the sieving plate 9 is provided with a second sieving screen 11, and the front end of the sieving plate 9 is provided with a discharge chute 10. The second sieving screen 11 is also used to sieve the green thorn flower tea raw material. The first impeller 5 and the second impeller 12 are connected by a transmission component, which includes a pulley 13 and a transmission belt 14. The rear ends of the first impeller 5 and the second impeller 12 are both connected to the pulley 13. A transmission belt 14 is provided on the two pulleys 13. Both pulleys 13 are single-groove designs.

[0022] When a batch of raw materials for thorn flower tea needs to be screened, the staff first starts the servo motor 8 of this utility model. At the same time, the staff preheats the screening and drying drum 2 on the support 1 separately. The servo motor 8 drives the first impeller 5 installed in the screening and drying drum 2 to rotate slowly. Through the pulley 13 connected to the first impeller 5, the pulley 13 at the other end of the transmission belt 14 rotates in the same direction. The second impeller 12 will also rotate. At this time, the staff puts the raw materials into the hopper 4 and continues to heat the screening and drying drum 2. The raw materials are evenly put into the screening and drying drum 2 in batches under the rotation of the second impeller 12. The space between the blades of the first impeller 5 in the screening and drying drum 2 will also separate the raw materials put in batches. The partition 6 installed between the blades helps the internal hot air to circulate. The raw materials are dried during the rotation of the first impeller 5. During the rotation of the first impeller 5, the fine raw materials that do not meet the quality requirements will be screened out through the first screening screen 3 and the second screening screen 11. The fine raw materials fall onto the front pull-out frame 15. Gradually, only raw materials meeting the required grade are left in the screening and drying drum 2 until the first screening screen 3 and the second screening screen 11 no longer screen out fine raw materials, and the screened raw materials are fully dried. Then, the worker pulls the pull-out frame 15 forward on the support 1, so that the pull-out frame 15 is below the discharge port. The screening plate 9 is pushed backward, and the position of the second screening screen 11 is replaced by the hollow discharge chute 10. The dried and screened raw materials will also be discharged through the discharge chute 10 and along the inclined surface of the inclined block into the square pull-out frame 15, and will be properly collected and stored by the worker. After that, the worker pulls the screening plate 9 again to return the second screening screen 11 to the initial position and puts the next batch of raw materials into the lower hopper 4 for screening and drying.

[0023] The sieved fine raw materials can be collected in storage compartment 16. The staff can pull out the drawer 15 separately and properly store the fine raw materials in storage compartment 16. The other storage compartment 16 at the rear of the drawer 15 can continue to collect fine raw materials when the staff stores the front storage compartment 16, so that the fine raw materials will not spill out of the drawer 15. After a batch of raw materials is sieved and dried, the storage compartment 16 can also be used to store the raw materials that have been sieved and dried, which is convenient for the staff to manage and store.
