[0037] The working principle of the electrostatic dust removal device for white tea processing in the utility model:

[0038] When the electrostatic dust removal device is used for white tea processing, the tea leaves are sent into the tea conveyor by the external tea delivery equipment, and the tea leaves are transported by the tea conveyor. The tea leaves are first flattened and guided by the guide plate in the adjustable guide structure to adjust the tea leaves to a state suitable for subsequent screening work. The tea leaves then enter the screening mechanism, and the reciprocating comb tooth structure in the screening mechanism simulates manual combing of the tea leaves to put the tea leaves in a good dust removal state. The tea leaves then pass through the electrostatic generator and enter the working range of the electrostatic dust collector to carry out electrostatic dust removal. The tea conveyor will send the tea leaves after electrostatic dust removal and static elimination to the next process.

[0039] When the tea leaves are sent into the working range of the screening mechanism by the tea conveyor, the tea leaves first come into contact with the height limiting protective plate, controlling the tea leaves to the same height, and then enter the reciprocating comb tooth structure, where the piled tea leaves are re-dispersed by a number of rows of needles, expanding the gaps between the tea leaves and shaking off the impurities adhering to the tea leaves, making it easier for the electrostatic precipitator to carry out electrostatic precipitation work, thereby improving the efficiency of continuous electrostatic precipitation of the tea leaves.

[0040] When the working thickness of the tea leaves needs to be controlled, the working thickness of the tea leaves on the subsequent tea conveyor can be adjusted by adjusting the adjustable guide structure, and the overall laying state of the tea leaves can be adjusted. Subsequently, the working thickness of the tea leaves entering the screening mechanism can be accurately controlled by the height limiting protective plate.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
