Technical Field

[0001] This utility model belongs to the field of tea processing technology, and in particular to a tea cleaning device. Background Technology

[0002] Tea is a famous beverage unique to my country, sold both domestically and internationally. Tea leaves can be consumed as a beverage, containing various beneficial components and offering health benefits. However, during the tea-growing process, tea leaves inevitably accumulate dust, pesticide residues, acid rain residues, heavy metals, and other contaminants. Therefore, harvested tea leaves must be washed before further processing. However, current washing equipment often leaves some tea leaves stuck to the inner wall of the equipment, making it difficult to remove them. This requires workers to remove the stuck tea leaves one by one, increasing their workload and reducing the efficiency of tea washing.

[0003] A Chinese patent (authorization announcement number CN212520654U) discloses a cleaning and impurity removal device for tea production, which includes: "a cleaning tank, a drain pipe fixedly installed at the bottom right side of the cleaning tank, a water injection pipe fixedly installed at the top right side of the cleaning tank, a mesh cylinder fixedly installed inside the cleaning tank, and a sewage discharge pipe fixedly connected to the middle of the bottom surface of the mesh cylinder."

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 5 The tea cleaning device shown includes a cleaning tank 1, with a support leg installed on the bottom surface of the cleaning tank 1. The inner cavity of the cleaning tank 1 is provided with a cleaning cylinder 2 for placing and cleaning tea leaves. The top surface of the cleaning cylinder 2 is provided with a cylinder cover 10, which allows the tea leaves to be cleaned to be placed into the cleaning cylinder 2. After placement, the cylinder cover 10 is secured to the top surface of the cleaning cylinder 2.

[0028] A water pump 15 for conveying clean water and a drain pump 14 for discharging clean water are respectively installed on one side of the cleaning tank 1. Both the water pump 15 and the drain pump 14 are connected to the cleaning tank 1 by a connecting pipe 18. The water pump 15 is connected to an inlet pipe 17 for conveying clean water. The inlet pipe 17 is connected to a water supply device. After the tea leaves are placed in the tank, the water pump 15 is turned on, so that the water pump 15 conveys the clean water in the external water supply device to the inlet pipe 17, and the clean water passes through the inlet pipe 17 and the connecting pipe 18 into the cleaning tank 1. At the same time, the clean water in the cleaning tank 1 submerges the tea leaves in the cleaning cylinder 2, which facilitates cleaning.

[0029] The drain pump 14 is connected to the drain pipe 16 for discharging clean water. After the tea leaves in the washing tank 2 are washed, the drain pump 14 is turned on, and the drain pump 14 discharges the water in the washing tank 1 through the connecting pipe 18 to the drain pipe 16. The water can then be discharged from the washing tank 1 through the drain pipe 16, and the washed water is filtered for easy recycling later.

[0030] A drive motor 11 is installed on the inner bottom surface of the cleaning tank 1. The output end of the drive motor 11 passes through the cleaning tank 1 and is connected to a turntable 12. Multiple support legs 13 are welded to the top surface of the turntable 12. The free ends of the multiple support legs 13 are all connected and fixed to the bottom surface of the cleaning cylinder 2. After the tea leaves are submerged in clean water, the drive motor 11 is turned on. The drive motor 11 drives the turntable 12 to rotate, which in turn drives the cleaning cylinder 2 to rotate through the support legs 13, so that the clean water is in a flowing state. The water waves generated by the flowing clean water clean the tea leaves in the cleaning cylinder 2.

[0031] Vertical grooves 3 are provided on both inner walls of the washing cylinder 2. Vertical plates 4 are slidably installed in the inner cavities of the two vertical grooves 3. A pad 5 for holding tea leaves is welded to one side of the two vertical plates 4 facing each other. A rubber scraper 6 for scraping off sticky tea leaves is installed on the top surface of the pad 5. The four sides of the rubber scraper 6 are respectively attached to the four inner walls of the washing cylinder 2. Several drainage holes 7 for water to pass through are equidistantly provided on the top surface of the pad 5, the periphery of the washing cylinder 2, and the inner bottom surface of the washing cylinder 2. After the tea leaves are washed, the cylinder cover 10 is removed to take out the washed tea leaves. If some tea leaves stick to the inner wall of the washing cylinder 2, the person pulls the two vertical grooves 4. The vertical plate 4 moves the pad 5 upward, which in turn moves the rubber scraper 6 upward. Since the four sides of the rubber scraper 6 are in contact with the four inner walls of the washing cylinder 2, the rubber scraper 6 can remove the tea leaves adhering to the inner wall of the washing cylinder 2 as it moves. The removed tea leaves will fall onto the surface of the pad 5. After the personnel remove the pad 5 from the inner cavity of the washing cylinder 2, the removal of the adhering tea leaves is completed. This avoids the situation where some tea leaves are still adhering to the inner wall of the washing cylinder 2 after washing, requiring personnel to remove the adhering tea leaves one by one. This not only reduces the workload of the staff but also improves the efficiency of tea washing.

[0032] One of the vertical slots 3 has a screw hole 8 on its top surface, and one of the vertical plates 4 has a threaded rod 9 that is threadedly connected to the screw hole 8 via a pin on its bottom surface. When the vertical plate 4 is placed into the cavity of the vertical slot 3, the position of the threaded rod 9 will be aligned with the position of the screw hole 8. When the threaded rod 9 moves downward with the vertical plate 4 and abuts against the screw hole 8, because the threaded rod 9 is rotatably connected to the vertical plate 4 via the pin, the downward movement of the vertical plate 4 will drive the threaded rod 9 into the cavity of the screw hole 8, and it will rotate in the cavity of the screw hole 8 through the thread. At the same time, with the self-locking of the thread, the threaded rod can be locked in place. 9 is fixed in the inner cavity of the screw hole 8, thereby fixing the positions of the two vertical plates 4 and the pad 5 in the inner cavity of the cleaning cylinder 2, preventing the positions of the vertical plates 4 and the pad 5 from shifting when the cleaning cylinder 2 rotates. If it is necessary to remove the vertical plates 4 and the pad 5, the personnel only need to pull the vertical plates 4 upward, so that the vertical plates 4 drive the threaded rod 9 to move upward, so that the threaded rod 9 can rotate in the opposite direction in the inner cavity of the screw hole 8, so that the threaded rod 9 can be removed from the inner cavity of the screw hole 8, thereby canceling the fixing of the vertical plates 4, and the vertical plates 4 and the pad 5 can be removed from the inner cavity of the cleaning cylinder 2.

[0033] Working principle:

[0034] The tea washing device involves placing the tea leaves to be washed into the washing cylinder 2 and securing the cylinder cover 10 to the top of the washing cylinder 2. At this point, a water pump 15 delivers clean water from an external water supply device to the inlet pipe 17, and then through the connecting pipe 18 to the washing tank 1, ensuring the water in the washing tank 1 submerges the tea leaves in the washing cylinder 2. The drive motor 11 is then activated, causing the turntable 12 to rotate. This, in turn, rotates the washing cylinder 2 via the support legs 13, keeping the water flowing. The resulting water waves clean the tea leaves within the washing cylinder 2. After cleaning, the personnel remove the cylinder cover 10 to retrieve the cleaned tea leaves. When some tea leaves are stuck to the inner wall of the cleaning cylinder 2, the personnel pull the vertical plate 4, causing the vertical plate 4 to move the pad 5 upward. This simultaneously moves the rubber scraper 6 upward, allowing the rubber scraper 6 to remove the tea leaves stuck to the inner wall of the cleaning cylinder 2. The removed tea leaves will fall onto the surface of the pad 5. After the pad 5 is removed from the inner cavity of the cleaning cylinder 2, the removal of the stuck tea leaves is complete, avoiding the need for personnel to remove the stuck tea leaves one by one, thereby improving the efficiency of tea cleaning.
