Description

Technical Field

[0001] This utility model relates to the field of air-dispersing devices, specifically an air-dispersing device for fixing tea leaves. Background Technology

[0002] In tea processing, fixation (or killing the green) is a crucial step. Its purpose is to use high temperatures to destroy and deactivate the oxidase activity in fresh leaves, inhibiting the enzymatic oxidation of substances like tea polyphenols, evaporating some moisture, softening the tea leaves for easier rolling and shaping, and simultaneously removing any grassy odor while promoting the formation of a pleasant aroma. Wind-drying is a step following fixation, primarily involving spreading the fixed tea leaves out to cool naturally. Simultaneously, the wind further evaporates moisture from the tea leaves, achieving the goal of drying.

[0003] However, the traditional spreading and drying process requires turning the tea leaves over for a period of time; otherwise, the leaves will not be evenly air-dried and will not dry sufficiently. Repeatedly turning the leaves over is not only labor-intensive and time-consuming, but also inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a wind-dispersing device for fixing tea leaves. The tea leaves are fed into the conveyor belt from the feed pipe, and then transported to the side of the air duct under the transmission of the conveyor belt. Under the action of the dispersing rod, they are evenly dispersed. Then, under the action of the high-pressure air pump and the air duct, they are continuously blown up and fall to the right side of the conveyor belt. This process is repeated continuously. It can not only evenly and efficiently disperse the tea leaves, greatly improving the dispersion efficiency, but also automates the operation and is simple to operate.

[0005] To achieve the above objectives, a wind-dispersing device for fixing tea leaves is provided, comprising: a wind-dispersing box, a feed pipe fixedly connected to the top of the wind-dispersing box, a baffle plate fixedly connected to the inner left side wall of the wind-dispersing box, the baffle plate being inclined, an air duct fixedly connected to the inner left side wall of the wind-dispersing box, an air outlet provided on the circumferential surface of the air duct, an inner filter screen fixedly connected inside the air outlet, a high-pressure air pump fixedly connected to the left side wall of the wind-dispersing box, a drive shaft, a driven shaft, and a dispersing shaft rotatably connected inside the wind-dispersing box, the driven shaft being located to the right of the drive shaft, a transmission belt being drivenly connected to the circumferential surfaces of the drive shaft and the driven shaft, a dispersing rod being fixedly connected to the circumferential surface of the dispersing shaft, the dispersing rod being multiple and evenly distributed on the dispersing shaft, and a main motor and a small motor fixedly connected to the rear side wall of the wind-dispersing box.

[0007] According to the aforementioned air-dispersing device for fixing tea leaves, the baffle plate is located above the conveyor belt, and the air outlet faces the space between the baffle plate and the conveyor belt. This allows the high-speed airflow to pass directly between the baffle plate and the conveyor belt.

[0008] According to the aforementioned air-dispersing device for fixing tea leaves, the output end of the small motor is fixedly connected to the dispersing shaft. Starting the small motor causes the dispersing shaft to rotate, thereby dispersing the tea leaves.

[0010] According to the aforementioned air-dispersing device for fixing tea leaves, the side filter is located above the sealing plate and above the conveyor belt. Gas inside the air-dispersing box is discharged through the side filter.

[0011] According to the aforementioned air-dispersing device for fixing tea leaves, the sealing plate and the air-dispersing box are rotatably connected by hinges and fixed by fastening bolts.

[0012] According to the aforementioned air-dispersing device for fixing tea leaves, the main motor is a reversible motor, and the output end of the main motor is fixedly connected to the drive shaft. When the main motor reverses, the air-dispersed tea leaves can be discharged.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up an air distribution box, a feed pipe, a baffle plate, an air duct, an inner filter screen, a high-pressure air pump, a drive shaft, a driven shaft, a conveyor belt, a dispersing shaft, and a dispersing rod, tea leaves are fed into the area above the conveyor belt through the feed pipe. Then, under the transmission of the conveyor belt, the tea leaves are transported to the side of the air duct. Under the action of the dispersing rod, the tea leaves are evenly dispersed. Then, under the action of the high-pressure air pump and the air duct, the tea leaves are continuously blown up and fall to the right side of the conveyor belt. This process is repeated continuously. This not only allows for even and efficient air dispersion of the tea leaves, greatly improving the air dispersion efficiency, but also automates the operation and makes it simple to operate.

A high-pressure air pump 6 is connected, and the output end of the high-pressure air pump 6 is connected to the air duct 4. When the high-pressure air pump 6 is started, a high-speed airflow is blown out of the air outlet of the air duct 4. The air distribution box 1 is rotatably connected to a drive shaft 7, a driven shaft 8, and a dispersion shaft 10. The driven shaft 8 is located to the right of the drive shaft 7. A transmission belt 9 is driven and connected to the circumferential surfaces of the drive shaft 7 and the driven shaft 8. The wind baffle 3 is located above the transmission belt 9, and the air outlet faces the space between the wind baffle 3 and the transmission belt 9, so that the air blown out of the air duct 4 is always directed towards the wind baffle. Between the 3rd and the conveyor belt 9, the tea leaves are blown up and fall to the right side of the conveyor belt 9. The maximum lift of the tea leaves is less than the length of the conveyor belt 9. Dispersing rods 11 are fixedly connected to the circumference of the dispersing shaft 10. There are multiple dispersing rods 11, which are evenly distributed on the dispersing shaft 10. The dispersing rods 11 are located above the conveyor belt 9, and the dispersing shaft 10 is located to the left of the feed pipe 2. The main motor 16 and the small motor 17 are fixedly connected to the rear side wall of the air dispersing box 1. The output end of the small motor 17 is fixedly connected to the dispersing shaft 10. When the small motor 17 is working, it can make the dispersing shaft 10 rotate, so that the dispersing rods 11 comb the tea leaves below and make them evenly conveyed to the left. The main motor 16 is a forward and reverse reversible motor. The output end of the main motor 16 is fixedly connected to the drive shaft 7. When the tea leaves are air dispersed, the main motor 16 works, making the drive shaft 7 rotate, thereby driving the tea leaves on the conveyor belt 9 to be conveyed to the left. The direction of movement of the dispersing shaft 10 is opposite to the conveying direction of the conveyor belt 9.

[0023] A sealing plate 12 is provided on the right side wall of the air distribution box 1. A handle 13 is fixedly connected to the right side wall of the sealing plate 12. A fixing plate 14 is fixedly connected to the right side wall of the sealing plate 12. A fastening bolt 15 is threadedly connected to the fixing plate 14.

A side filter screen 18 is fixedly connected to the right side wall of the air distribution box 1. The side filter screen 18 is located above the sealing plate 12 and above the conveyor belt 9 to facilitate the internal airflow to be discharged through the side filter screen 18.

[0024] Working principle: Tea leaves are fed into the air distribution box 1 through the feed pipe 2 onto the conveyor belt 9. Then, the main motor 16, the small motor 17, and the high-pressure air pump 6 are started. The tea leaves are conveyed to the left by the movement of the conveyor belt 9. After being dispersed by the dispersing rod 11, they move evenly towards the air duct 4. The high-speed airflow blown out of the air duct 4 passes through the baffle plate 3 and goes directly between the baffle plate 3 and the conveyor belt 9, thereby blowing the tea leaves up and letting them fall on the far right side of the conveyor belt 9. This process is repeated to continuously disperse the tea leaves, thereby achieving uniform and efficient air dispersion. After the air dispersion is completed, the conveyor belt 9 is started in reverse, the sealing plate 12 is opened, and the tea leaves are discharged.
