Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tea processing equipment, in particular to a selenium-enriched tea grading device. Background Art
[0002] Selenium-rich tea refers specifically to tea rich in selenium, usually produced in selenium-rich areas. Selenium-rich tea has the effects of reducing fat and weight, preventing cardiovascular and cerebrovascular diseases, calming the nerves, enhancing immunity, and anti-aging, so it is more popular among consumers.
[0003] In the prior art, a Chinese utility model with publication number CN215587072U discloses a grading device for selenium-enriched tea leaves, comprising a chassis, a screening mechanism, a feeding mechanism and a first-stage screen. The screening mechanism comprises a centrifugal screen cylinder located in the chassis, the centrifugal screen cylinder is used to separate tea leaves, the centrifugal screen cylinder is horizontally arranged, one end of the centrifugal screen cylinder is connected to a rotating shaft, the rotating shaft is movably connected to the inner wall of the chassis through a ball bearing, the other end of the centrifugal screen cylinder is connected to a feeding pipe, the feeding mechanism comprises an arc tube, one end of the arc tube is movably connected to the feeding pipe through a ball bearing, the other end of the arc tube extends out of the chassis and is connected to a feeding hopper, the first-stage screen is located directly below the centrifugal screen cylinder, the first-stage screen is used to filter impurities, and the filtering accuracy of the first-stage screen is greater than the filtering accuracy of the centrifugal screen cylinder.
[0004] In the above technology, tea leaves are added through a feed hopper. After the tea leaves enter the centrifugal screen cylinder, they are subjected to the first impurity removal under the rotating centrifugal action of the centrifugal screen cylinder. The tea leaves are thrown out and fall on the first-stage screen below for secondary impurity treatment. The first-stage screen can filter out impurities with smaller volumes and retain the tea leaves, thereby fully filtering impurities of different volumes. However, during filtering, the tea leaves and fine impurities are only filtered once through the first-stage screen. When there are also tea leaves with smaller volumes attached to the impurities, they will also be filtered out with the first-stage screen. If multiple filtrations are not performed, tea leaves may be wasted. Utility Model Content

[0030] The centrifugal drum 4 is driven to rotate by the output shaft of the driving motor 3, so that the centrifugal drum 4 can filter the tea leaves for the first time during the rotation process, and the impurities and tea leaves rotated out of the centrifugal drum 4 will fall on the first filter plate 5 for the second filtration, and then the tea leaves and impurities continue to fall, and the tea leaves and impurities fall on the inclined filter plate 6 for the third filtration, and the filtered impurities are sucked back and transported to the inside of the grading box 1 through the extraction pump in the reflux pipe 10. Prior to this, the first filter plate 5 is taken out of the grading box 1, and then replaced with a filter plate with a finer mesh number, so that the filtered impurities can be filtered again, thereby making the separation of impurities and tea leaves more comprehensive and thorough.
[0031] Embodiment 2
[0032] On the basis of Example 1, mounting bars 12 are fixed on both sides of the inner wall of the grading box 1, and a supporting slide bar 13 is slidingly arranged inside the mounting bar 12. One side of the supporting slide bar 13 is fixed to one side of the first filter plate 5, and a material guide plate 14 is fixed to one side of the inclined filter plate 6.

After being filtered by the inclined filter plate 6, the impurities pass through the guide plate 1 4 enters the holding box 8. In order to avoid that smaller tea leaves are still mixed with the impurities, the filtered impurities are pumped back to the inside of the grading box 1 through the extraction pump in the reflux pipe 10. Before this, the first filter plate 5 is taken out of the grading box 1 and then replaced with a filter plate with a finer mesh. Therefore, the filtered impurities can be filtered again, thereby making the separation of impurities and tea leaves more comprehensive and thorough. The separated tea leaves will fall on the second filter plate 20 and be filtered again by the second filter plate 20. Then, larger tea leaves will accumulate on the second filter plate 20, and smaller tea leaves will fall into the collecting box 17. Therefore, the tea leaves can be sorted more comprehensively and carefully while removing impurities, thereby avoiding waste of tea leaves, saving cost and time, and improving efficiency.
