However, before processing wolfberry pulp, usually, the size and impurities of wolfberries are screened once, and the smaller wolfberries with lower selling prices are screened and processed into pulp.

[0003] The existing impurity removing and screening device for wolfberry pulp processing raw materials mainly focuses on the classification and screening of large and small particle wolfberries and obvious impurities, but fails to fully address the problem of separating adhered wolfberries. The adhesion of wolfberries not only affects the purity and screening efficiency of large particle wolfberries, but also adds additional subsequent processing steps. The adhered wolfberries need to be dried, dispersed separately and then returned to the screening process again. This series of operations undoubtedly increases the operating cost burden of the enterprise and slows down the overall production rhythm. Content of the Utility Model

One end of the return pipe 22 is communicated with the upper side of the feeding mechanism 8, and the screw elevator 7 is connected to one side of the feeding mechanism 8; when screening wolfberry raw materials, the wolfberry raw materials to be screened are added to the feeding mechanism 8, and the wolfberries to be screened are transported by the feeding mechanism 8 and added to the screening box 1 through the feed inlet 5. Large-grained wolfberries, small-grained wolfberries, and impurities fall downward through the screening of the uppermost screening mechanism 9 onto the next screening mechanism 9, while the adhered wolfberries in the wolfberries enter the drying and dispersing mechanism 6 through the uppermost discharge port 4. After being dried and dispersed by the drying and dispersing mechanism 6, they enter the screw elevator 7, are pushed upward by the screw elevator 7 and enter the feeding mechanism 8 through the return pipe 22, and re-enter the screening box 1 for screening. The large-grained wolfberries and small-grained wolfberries are respectively screened by the two screening mechanisms 9 below and discharged through the corresponding discharge ports 4. The impurities in the wolfberries enter the bottom of the screening box 1 through screening. Furthermore, this device can not only separate the adhered wolfberries during the screening process, but also immediately dry and disperse the adhered part of the wolfberries, and then seamlessly connect to the re-screening process, ensuring the purity and efficiency of the screening results. It also reduces the subsequent processing steps, reduces the operating costs of the enterprise, and speeds up the overall production progress.

[0019] The drying and dispersing mechanism 6 includes a processing housing 14 provided on one side of the screening box 1 and corresponding to the uppermost discharge port 4, a connecting pipe 15 communicating with the lower side of the processing housing 14, a dispersing device provided in the processing housing 14, a screening mesh 16 provided in the processing housing 14 and below the dispersing device, stainless steel air knives 17 provided on the top side of the inner wall of the processing housing 14 and on one side of the dispersing device respectively, and two hot air blowers 18 provided on the upper side of the processing housing 14. The air outlet pipes of the hot air blowers 18 communicate with the upper side of the stainless steel air knives 17. One end of the connecting pipe 15 communicates with the bottom of the outer wall of the screw elevator 7. After the agglomerated goji berries are screened and enter the processing housing 14, the hot air generated by the two hot air blowers 18 respectively enters the two stainless steel air knives 17, and then enters the processing housing 14 to dry the agglomerated goji berries. While drying, the agglomerated goji berries are dispersed by the dispersing device. After being screened by the screening mesh 16, the dispersed goji berries enter the screw elevator 7 through the connecting pipe 15. Thus, it is convenient to dry and disperse the agglomerated goji berries entering the processing housing 14.

[0020] The dispersing device includes a driving motor 19 provided on the upper side of the processing housing 14 and between the two hot air blowers 18, a rotating shaft 20 connected to the output end of the driving motor 19 and located in the processing housing 14, and a plurality of dispersing rods 21 provided on the outer wall of the rotating shaft 20 and arranged at intervals.

[0021] The screening mechanism 9 includes vibration seats respectively provided on both sides of the inner wall of the screening box 1, a screening mesh plate 12 provided on the upper side of the two vibration seats, and a vibration motor 13 provided on the lower side of the screening mesh plate 12 and between the two vibration seats. One end of the uppermost screening mesh plate 12 passes through the discharge port 4 and extends into the interior of the processing housing 14. The goji berries fall onto the screening mesh plate 12, and the vibration motor 13 cooperates with the two vibration seats to drive the screening mesh plate 12 to vibrate, realizing vibration screening of the goji berries.

[0022] The vibration seat includes a mounting plate 10 connected to the inner wall of the screening box 1 and a plurality of springs 11 provided on the upper side of the mounting plate 10 and arranged at intervals. One end of the springs 11 is connected to the lower side of the screening mesh plate 12. During vibration screening, the plurality of springs 11 work together to drive the screening mesh plate 12 to vibrate. This action not only ensures the stability of screening but also effectively promotes the efficient separation of the goji berry raw materials on the screening mesh plate 12.

[0023] The feeding mechanism 8 includes a conveying housing 23 connected to the upper side of the screening box 1, a feeding hopper 24 communicating with the upper side of the conveying housing 23 and located on one side of the return pipe 22, and a conveyor belt 25 provided in the conveying housing 23. One end of the conveying housing 23 near the feeding port 5 is provided with an opening, one end of the conveyor belt 25 corresponds to be above the feeding port 5, and one end of the return pipe 22 communicates with the upper side of the conveying housing 23. The wolfberry raw materials to be screened are added onto the conveyor belt 25 in the conveying housing 23 through the feeding hopper 24, and the wolfberries after being broken up and conveyed through the return pipe 22 also fall onto the conveyor belt 25. The wolfberries to be screened are conveyed by the conveyor belt 25 and enter the screening box 1 through the feeding port 5, thus facilitating the conveyance and addition of the wolfberry raw materials to be screened and the dried and broken-up wolfberries into the screening box 1.

[0024] On the top side of the inner wall of the conveying housing 23, there is a scraping plate 26 located on one side of the feeding hopper 24. During the conveying process, for the wolfberry raw materials on the conveyor belt 25, the scraping plate 26 scrapes the piled-up wolfberry raw materials to make them thinner, preventing the piled-up wolfberry raw materials from being added into the screening box 1 and affecting the screening accuracy.

[0025] The lower side of the screening box 1 communicates with an inclined bin 2, and the lower end of the inclined bin 2 communicates with a waste discharge pipe 3. The impurities are discharged through the waste discharge pipe 3.

[0026] On one side of the screening box 1, there is a controller which is electrically connected to the conveyor belt 25, the vibration motor 13, the hot air blower 18, the drive motor 19, and the screw elevator 7. The controller controls the opening and closing of the conveyor belt 25, the vibration motor 13, the hot air blower 18, the drive motor 19, and the screw elevator 7.

[0027] Working principle: When screening wolfberry raw materials, the conveyor belt 25, vibration motor 13, hot air blower 18, drive motor 19, and screw elevator 7 are controlled by the controller to be turned on. The wolfberry raw materials to be screened are added onto the conveyor belt 25 inside the conveying housing 23 through the feed hopper 24. The wolfberries to be screened are conveyed by the conveyor belt 25, and the piled-up wolfberry raw materials are scraped thin by the scraping plate 26. Then, the wolfberry raw materials enter the screening box 1 through the feed port 5. Large-particle wolfberries, small-particle wolfberries, and impurities fall downward onto the next screening mechanism 9 under the screening of the uppermost screening mechanism 9. The vibration motor 13 cooperates with two vibration seats to drive the screen plate 12 to vibrate, realizing vibration screening of the wolfberries. During vibration screening, the vibration motor 13 cooperates with two vibration seats to drive the screen plate 12 to vibrate, and multiple springs 11 work together to realize vibration screening of the wolfberries. The wolfberries that are adhered to each other in the wolfberries enter the treatment housing 14 through the uppermost discharge port 4. The hot air generated by the two hot air blowers 18 enters the two stainless steel air knives 17 respectively, and then enters the treatment housing 14 to dry the adhered wolfberries. While drying, the drive motor 19 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives multiple dispersing rods 21 to rotate to disperse the adhered wolfberries during the drying process. After being screened by the screening net 16, the dispersed wolfberries enter the screw elevator 7 through the connecting pipe 15, are pushed upward by the screw elevator 7, enter the conveying housing 23 through the return pipe 22, and fall onto the conveyor belt 25, and re-enter the screening box 1 for screening. The large-particle wolfberries and small-particle wolfberries are respectively screened by the two screening mechanisms 9 located below and discharged through the corresponding discharge ports 4. The impurities in the wolfberries enter the bottom of the screening box 1 through screening and are discharged through the impurity discharge pipe 3. Furthermore, this device can not only separate the adhered wolfberries during the screening process, but also immediately dry and disperse the adhered part of the wolfberries, and then seamlessly connect to the re-screening process, ensuring the purity and efficiency of the screening results. It also reduces the subsequent processing steps, lowers the operating costs of the enterprise, and speeds up the overall production progress.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
