Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a rotary tea drying and dust removal device. Background Technology

[0002] Tea leaves often need to be washed after picking. After washing, in order to quickly enter the next production process, they usually need to be dried, which requires the use of drying equipment, as shown below.

[0003] A search revealed a patent with publication number CN219810189U, which discloses a tea drying device. The device includes a housing with a built-in chamber, a mesh rotating drum, a feed hole, a sealing door, an air conveying component, a heating component, and a transmission pipe. The transmission pipe passes through the housing and the mesh rotating drum, and its middle section is rotatably connected to the mesh rotating drum. The air conveying component is fixedly connected to the housing, and the end of the transmission pipe away from the mesh rotating drum is connected to the air conveying component via a pipe. The air conveying component can transmit airflow into the transmission pipe. The heating component is fixedly connected inside the transmission pipe and can heat the airflow inside the transmission pipe, increasing the efficiency of tea drying and preventing poor internal drying due to tea accumulation. Furthermore, the rotary heating method can improve the uniformity of tea drying.

[0004] However, the aforementioned tea drying device still has the following areas for improvement. For example, although it can dry tea well, a large amount of tea dust is inevitably generated during the rotary drying process. This tea dust will be scattered inside the chamber and will also be dispersed into the surrounding air after the chamber is opened, causing pollution inside the chamber and the surrounding environment. This increases the workload of cleaning the inside of the chamber and may endanger nearby workers, posing a significant safety hazard. At the same time, the tea dust can also re-adhere to the tea, reducing the production quality of the tea. Therefore, a rotary tea drying dust removal device is urgently needed to solve the above technical problems. Utility Model Content

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0031] Reference Figures 1-3A rotary tea drying and dust removal device includes a base 1, a drying box 2 fixedly mounted on the top of the base 1, a working door 3 hinged to the front of the drying box 2; a supporting mechanism 4 located inside the drying box 2; and a drying mechanism 5 located on one side and inside the drying box 2.

[0032] The dust removal mechanism 6 includes a cylinder 601 and a dust collection box 602. The cylinder 601 is fixedly installed in a through-type manner on the top of the drying oven 2. The telescopic end of the cylinder 601 is fixedly connected to a lifting seat 603. The bottom of the lifting seat 603 is fixedly connected to multiple actuating rods 604. The bottom end of the actuating rods 604 is a smooth arc surface. The position of the actuating rods 604 matches the position of the supporting mechanism 4. There are two dust collection boxes 602, both of which are fixedly installed on the top of the drying oven 2. The top of the dust collection boxes 602 is fixedly mounted... The dust collection box 602 is equipped with an exhaust fan 605. The exhaust end of the exhaust fan 605 is connected to one side of the dust collection box 602. The other side of the dust collection box 602 is connected to a first duct 606. Two second ducts 607 are installed in a through-type manner at the lifting seat 603. The second ducts 607 are connected to the first duct 606 by a flexible hose 608. The bottom of the second ducts 607 is connected to a dust collection hood 609. The two dust collection hoods 609 are respectively angled towards both sides of multiple levers 604. The dust collection box 602 is equipped with a filter screen plate 610 inside.

[0033] The working door 3 is provided with a transparent observation window 7, and the front of the working door 3 is provided with an inner groove 8; the front of the dust collection box 602 is hinged with a box door 611, and the box door 611 is sealed to the dust collection box 602 when closed.

[0034] In the specific implementation process, during operation, tea leaves can be placed in the carrying mechanism 4, and hot air is blown into the interior of the drying chamber 2 and the carrying mechanism 4 through the drying mechanism 5 to dry the tea leaves. During this process, two exhaust fans 605 are started, working in conjunction with the dust collection box 602, the first duct 606, the hose 608, and the second duct 607 to generate negative pressure suction at the dust collection hood 609. This allows a large amount of tea leaf dust to be drawn into the dust collection box 602, where it is intercepted and filtered by the filter plate 610 and left in the dust collection box 602. Finally, clean air is discharged through the exhaust end of the exhaust fan 605. In this way, it is possible to effectively prevent a large amount of dust from drifting into the interior of the chamber, into the surrounding air, and re-attaching to the tea leaves. This effectively reduces the intensity of subsequent cleaning work inside the chamber, avoids harming nearby workers, and effectively prevents a reduction in the quality of tea production.

[0035] Among them, the observation window 7 is to facilitate the staff to observe the internal condition of the drying oven 2, while the inner groove 8 is to facilitate the staff to open the working door 3;

[0036] The dust collection box 602 can be cleaned by opening the door 611, and the filter screen 610 can be cleaned and replaced. Specific Implementation Example 2:

[0038] Reference Figures 3-6 In a preferred embodiment, the bearing mechanism 4 includes a motor 401, a rotating seat 402, and a bearing plate 403. The output end of the motor 401 is connected to a rotating shaft 404. The rotating seat 402 is annular. A connecting seat 405 is fixedly connected to the inner bottom surface of the rotating seat 402 by multiple connecting rods. The bottom of the connecting seat 405 is fixedly connected to the top of the rotating shaft 404. Multiple slots 406 are provided at the top opening of the rotating seat 402. Multiple locking blocks 407 are provided on the outer side of the bearing plate 403. The bearing plate 403 matches and engages with the interior of the rotating seat 402, and the multiple locking blocks 407 respectively match and engage with the multiple slots 406. The top of the bearing plate 403 is an open design, and multiple through holes 408 are provided on the inner bottom surface of the bearing plate 403.

[0039] Two handles 409 are fixedly connected to the top of the support plate 403, and the two handles 409 are respectively close to the two sides of the support plate 403; an annular guide seat 9 is fixedly installed inside the drying oven 2, and a sliding groove 10 is opened on the inner side of the guide seat 9. The outer side of the rotating seat 402 is slidably connected to the sliding groove 10 through multiple sliding connectors.

[0040] The drying mechanism 5 includes a hot air blower 501, which is fixedly installed on the outside of the drying chamber 2 by a mounting component. The air outlet of the hot air blower 501 is connected to an air supply pipe 502, and the other end of the air supply pipe 502 is connected to an annular pipe 503. The top of the annular pipe 503 is connected to multiple air outlet branch pipes 504, which are all located below the support plate 403. The bottom of the annular pipe 503 is connected to the inner bottom surface of the drying chamber 2 by a support column 505.

[0041] In the specific implementation process, during operation, first open the working door 3, lift the bearing plate 403 to separate it from the rotating seat 402, and then remove the bearing plate 403 to the outside of the drying chamber 2. Pour the tea leaves into the bearing plate 403, and then reset the bearing plate 403. When resetting the bearing plate 403, align the multiple limiting blocks with the limiting grooves and move the bearing plate 403 down until the limiting blocks and limiting grooves engage. The bearing plate 403 can then engage with the rotating seat 402 and rotate synchronously. At this time, the motor 401 works, driving the rotating seat 402 to rotate slowly, thereby driving the bearing plate 403 to rotate. The tray 403 and the tea leaves inside rotate slowly, and the hot air blower 501 works in conjunction with the air supply pipe 502, the annular pipe 503 and multiple air outlet branch pipes 504 to blow hot air evenly towards the bottom of the tray 403. The hot air dries the tea leaves through multiple through holes 408. After the drying process is completed, the tray 403 is removed and taken out to the outside of the drying box 2, and the tea leaves inside can be poured out quickly and conveniently, completing the tea leaf discharge. It is not affected by the internal space of the box, making the loading and unloading of tea leaves time-saving and labor-saving, and greatly improving work efficiency.

[0042] Working principle: During operation, first open the working door 3, lift the support plate 403 to separate it from the rotating seat 402, and then remove the support plate 403 to the outside of the drying chamber 2. Pour the tea leaves into the support plate 403, and then reset the support plate 403. When resetting the support plate 403, align multiple limit blocks with the limit grooves and move the support plate 403 downwards until the limit blocks and limit grooves engage. The support plate 403 will then engage with the rotating seat 402 and rotate synchronously. Then, the cylinder 601 will operate, driving the lifting seat 603 downwards, thereby driving multiple actuating rods 604 downwards until the multiple actuating rods 604 are lowered. The tea leaves are brought close to the bottom surface of the support plate 403 but not in contact with it. Then, the motor 401 is started, which drives the rotating seat 402 to rotate slowly, thereby causing the support plate 403 and the tea leaves inside to rotate slowly. At the same time, the hot air blower 501 works, and together with the air supply pipe 502, the annular pipe 503 and multiple air outlet branch pipes 504, hot air is blown evenly toward the bottom of the support plate 403. The hot air dries the tea leaves through multiple through holes 408. When the support plate 403 rotates, multiple actuating rods 604 can turn and move the tea leaves inside the support plate 403, ensuring the uniformity and effect of drying the tea leaves.

[0043] During the above process, two exhaust fans 605 are activated, working in conjunction with the dust collection box 602, the first duct 606, the hose 608, and the second duct 607 to generate negative pressure suction at the dust collection hood 609. This allows a large amount of tea leaf dust to be drawn into the dust collection box 602, where it is filtered and retained by the filter plate 610. Finally, clean air is discharged through the exhaust fan 605. This effectively prevents the dust from being dispersed into the interior of the box, into the surrounding air, or re-attached to the tea leaves. Consequently, it effectively reduces the intensity of subsequent cleaning work inside the box, avoids harming nearby workers, and prevents a reduction in the quality of tea production.

[0044] After the tea drying process is completed, open the working door 3, start the cylinder 601 to drive the lifting seat 603 and the lever 604 to move upward, and remove the bearing plate 403 again to the outside of the drying box 2. The tea inside can then be poured out quickly and conveniently, completing the tea unloading process without being affected by the internal space of the box. This makes the loading and unloading of tea time-saving and labor-saving, greatly improving work efficiency.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
