Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to an impurity removal device used for tea processing. Background Art

[0002] Tea is made through steps such as spreading, extracting, drying, and selecting. Before making, tea needs to be cleaned to ensure the cleanliness and hygiene of the tea. Generally, impurities such as hair, chicken feathers, ash powder, etc. mixed in the tea are removed by electrostatic adsorption. Under the adsorption of electrostatic rollers, the efficiency of the impurity removal process is greatly improved, the amount of labor is reduced, and the quality and economic benefits of the tea are greatly improved.

[0003] However, when the existing tea processing impurity removal device is put into use, the staff is required to place the tea leaves on the conveyor belt. However, most of the tea leaves are piled up in one piece when placed, which makes it impossible for the electrostatic friction roller to adsorb some impurities inside the tea leaves, thereby reducing the effect of the device on tea impurity removal. At the same time, most tea leaves have a certain amount of moisture during electrostatic adsorption, which will cause some impurities to adhere to the surface of the tea leaves, resulting in a situation where the device is less comprehensive in removing impurities from the tea leaves.

[0022] See also Figure 1-5 The figure shows a device for removing impurities from tea leaves, comprising a support frame 1, a cleaning component 2 being provided on the top of the support frame 1, the cleaning component 2 being composed of a plurality of electrostatic friction rollers, and impurities on the surface of the tea leaves being adsorbed under the action of the cleaning component 2, a collecting component 3 being provided on the top of the support frame 1, the collecting component 3 being composed of a plurality of guide grooves and a collecting box, and impurities being moved to the interior of the collecting box through the collecting component 3 under the action of the cleaning component 2, thereby facilitating the collection of impurities by the staff, and a guide plate 4 being provided on one side of the support frame 1, and the guide plate 4 being able to guide and move the tea leaves that need to be cleaned, a stepping motor 5 being bolted to one side of the support frame 1, a rotating mechanism 6 being provided above the stepping motor 5, a support plate 8 being bolted to one side of the support frame 1, and a connecting rod 7 being slidably connected to the inner cavity of the support plate 8, and the rotating mechanism 6 and the connecting rod 7 being used in conjunction with each other, and the top of the connecting rod 7 and the bottom of the guide plate 4 being bolted to each other, and under the cooperation of the stepping motor 5 and the rotating mechanism 6, the connecting rod 7 can drive the guide plate 4 to move. The tea leaves on the top of the tea leaves are dried by the air conveying mechanism 13, thereby effectively preventing the tea leaves from piling up and causing the device to be unable to remove some impurities.

[0023] The rotating mechanism 6 includes a turntable 61, the bottom of which is fixedly connected to the output shaft of the stepper motor 5, and the central axis of the turntable 61 corresponds to the central axis of the output shaft of the stepper motor 5. A fixed block 62 is bolted to the top of the turntable 61, and a roller 63 is rotatably connected to the bottom of the connecting rod 7. The surface of the roller 63 is rollingly connected to the top of the fixed block 62. With the cooperation of the stepper motor 5 and the turntable 61, the fixed block 62 can be rotated at the bottom of the roller 63, so that the top of the fixed block 62 and the surface of the roller 63 are constantly intertwined and corresponding, and under the action of the support plate 8, the connecting rod 7 can drive the guide plate 4 to vibrate on one side of the support frame 1, which can separate the piled tea leaves, thereby increasing the effect of the device on removing impurities from the tea leaves. The cross-section of the fixed block 62 is trapezoidal in design.

[0024] The air delivery mechanism 13 includes a connecting pipe 131, one end of the connecting pipe 131 is communicated with the surface of the fan pump 10, the other end of the connecting pipe 131 is communicated with one side of the fixed shell 11, the other side of the fixed shell 11 is communicated with a transmission pipe 132, the other end of the transmission pipe 132 is communicated with a nozzle 133, the other end of the nozzle 133 is fixedly connected to the inner cavity of the U-shaped frame 9, one end of the nozzle 133 passes through the other side of the U-shaped frame 9 and is fixedly connected with the penetration point. With the cooperation of the fan pump 10 and the connecting pipe 131, air can enter the interior of the fixed shell 11, and then under the action of the heating pipe 12, the heated air can enter the interior of the nozzle 133 through the transmission pipe 132, and the surface of the tea leaves is dried through the nozzle 133, which effectively prevents the tea leaves that have not been decontaminated from being wet, resulting in a decrease in the decontamination effect, thereby increasing the practicality of the device.

[0025] Working principle: First, the staff places the tea leaves that need to be cleaned on the top of the guide plate 4, and then under the action of the stepper motor 5, the turntable 61 can drive the fixed block 62 to rotate. When the top of the fixed block 62 corresponds to the bottom of the roller 63, the guide plate 4 is moved upward through the connecting rod 7. When the top of the fixed block 62 and the bottom of the roller 63 are intertwined with each other, the guide plate 4 is moved downward through the connecting rod 7. Under the action of the support plate 8, the connecting rod 7 can drive the guide plate 4 to achieve a vibration effect, which can make the piled tea leaves evenly distributed on the top of the guide plate 4. When the plate 4 transfers the dispersed tea leaves to the bottom of the nozzle 133, with the cooperation of the fan pump 10 and the connecting pipe 131, the air can enter the interior of the fixed shell 11, and then the air is heated by the heating pipe 12. The heated air enters the interior of the nozzle 133 through the transmission pipe 132, and the tea leaves are dried through the nozzle 133. The tea leaves are transferred to the top of the conveyor belt through the guide plate 4. Under the action of multiple electrostatic friction rollers of the impurity removal component 2, the impurities inside the tea leaves can be collected by the collecting component 3. Then the staff will clean the collection box of the collecting component 3 and put it back to its original position.
