[0027] This embodiment provides a dust removal device for tea leaves, the structural schematic diagram of which is shown below. Figures 1-6 As shown, the device includes an outer cylinder 1 and a mesh-structured dust collection cylinder 2. The outer cylinder 1 is horizontally arranged, and a rotating frame 7 is rotatably mounted inside it. The outer cylinder 1 has an open end, and a motor 6 for driving the rotating frame 7 is mounted at the other end. The dust collection cylinder 2 is inserted into the outer cylinder 1 from the open end and nested with the rotating frame 7, and the dust collection cylinder 2 can rotate synchronously with the rotating frame 7. A bottom shell 4 is mounted at the bottom of the outer cylinder 1, and the bottom shell 4 and the interior of the outer cylinder 1 are interconnected. An air outlet 10 is opened at the bottom of the bottom shell 4, and multiple fans 11 are mounted inside the air outlet 10. Through this structure, After tea leaves are placed inside the dust sieving cylinder 2, it is inserted into the rotating frame 7 through the open end of the outer cylinder 1. The motor 6 is started to rotate the dust sieving cylinder 2 in conjunction with the rotating frame 7, causing the tea leaves inside the dust sieving cylinder 2 to tumble. During the tumbling process, the dust on the surface of the tea leaves is shaken off and falls into the bottom shell 4 through the mesh on the dust sieving cylinder 2. At the same time, the fan 11 in the air outlet 10 at the bottom of the bottom shell 4 is started to exhaust air downwards, which can suck out the dust shaken off the tea leaves, thereby achieving the purpose of removing dust from the tea leaves. After the tea leaves are dusted, the dust sieving cylinder 2 can be directly pulled out from the open end of the outer cylinder 1 for easy collection of tea leaves.
[0028] In this embodiment, a dust collection plate 5 is horizontally arranged inside the bottom shell 4. The dust collection plate 5 can be a sponge plate. The dust collection plate 5 is pulled out and assembled inside the bottom shell 4. The dust collection plate 5 can adsorb and collect the dust sucked by the fan 11, thereby reducing environmental pollution.
[0029] In this embodiment, the dust sieving cylinder 2 includes a fixing ring 14, and at least a pair of fixing strips 15 are connected between the pair of fixing rings 14. A filter screen 17 is connected between the fixing strips 15 and the pair of fixing rings 14. One of the fixing rings 14 has a closed end face, and the other fixing ring 14 is provided with an end cap 3. The end cap 3 is threadedly engaged with the fixing ring 14. The end cap 3 facilitates the filling and collection of tea leaves in the dust sieving cylinder 2. In addition, the fixing ring 14 equipped with the end cap 3 is also provided with a handle 16.
[0030] In this embodiment, the rotating frame 7 is configured as a U-shaped structure. The output shaft of the motor 6 is connected to the center of the closed end of the rotating frame 7. A slot 12 is provided on the inner side wall of the rotating frame 7 along the length direction. A protrusion 13 is provided on the outer surface of the fixing strip 15 along the length direction. The protrusion 13 fits into the slot 12. Through the fitting of the protrusion 13 and the slot 12, the dust sieve cylinder 2 can rotate synchronously with the rotating frame 7.
[0031] In a further embodiment, a paddle 18 is fixed on the inner wall of the fixed strip 15. The paddle 18 is arranged along the length of the dust sieve cylinder 2 and is inclined to one side. During the rotation of the dust sieve cylinder 2, the paddle 18, which is inclined on the inner wall of the fixed strip 15, can disperse the tea leaves, increase the tumbling range of the tea leaves, and improve the dust removal effect on the tea leaves.
[0032] In this embodiment, a sleeve block 8 is fixed on the end face of the bottom shell 4 facing the opening end of the outer cylinder 1. A baffle 9 is vertically and movably inserted into the top of the sleeve block 8. The top of the baffle 9 extends to the opening end of the outer cylinder 1. After the dust sieve cylinder 2 is inserted into the outer cylinder 1, the baffle 9 can be vertically inserted into the sleeve block 8 to prevent the dust sieve cylinder 2 from coming out of the outer cylinder 1.
[0033] Working principle: In use, tea leaves are loaded into the dust sifting cylinder 2, and the end cap 3 is closed. The dust sifting cylinder 2 containing tea leaves is inserted into the open end of the outer cylinder 1. The protrusion 13 on the dust sifting cylinder 2 engages with the slot 12 on the side wall of the rotating frame 7. Then, the baffle 9 is vertically inserted into the sleeve block 8 to prevent the dust sifting cylinder 2 from detaching from the outer cylinder 1. The motor 6 is started to drive the rotating frame 7 to rotate. Utilizing the engaging action of the protrusion 13 and the slot 12, the rotating frame 7 drives the dust sifting cylinder 2 to rotate, causing the tea leaves inside the dust sifting cylinder 2 to tumble. During the tumbling process, dust on the surface of the tea leaves is shaken off and falls through the filter screen 17 on the dust sifting cylinder 2 into the bottom shell 4. At the same time, the bottom shell is activated. The fan 11 inside the bottom air outlet 10 exhausts air downwards, which can suck up the dust shaken off the tea leaves and collect it through the dust collection plate 5, thereby achieving the purpose of removing dust from the tea leaves. In addition, during the rotation of the dust sieve cylinder 2, the diagonal blades 18 arranged at an angle on the inner wall of the fixed strip 15 can disperse the tea leaves, increase the tumbling range of the tea leaves, and improve the dust removal effect. Furthermore, after the tea leaves are dusted, the baffle 9 can be pulled away from the sleeve block 8, and the dust sieve cylinder 2 can be directly pulled out from the opening end of the outer cylinder 1. The end cover 3 can be opened to directly collect the dust-removed tea leaves. The overall structure is simple, the dust removal effect of the tea leaves is good, and it is convenient for filling and collecting tea leaves.
[0034] All technical features in this embodiment can be freely combined according to actual needs.
