The components of tea include catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, which are beneficial to health. The tea beverage made from tea is one of the three major beverages in the world.

[0003] For example, the patent document with the publication number of CN 220329408 U discloses a tea processing dust removal device, including a belt conveyor, a protective cover, and a ventilation box. The protective cover is fixed to the top of the belt conveyor by bolts. A water collecting pipe is installed on the top of the protective cover through a mounting frame. The bottom of the water collecting pipe is welded with connecting pipes at equal intervals. The bottom end of the connecting pipe is connected to a horizontal water pipe through a threaded groove. The bottom of the horizontal water pipe is connected to a nozzle through a threaded groove. One end of the top of the protective cover is fixed with a ventilation box by bolts. In the utility model, clean water is sprayed onto the surface of the tea through the nozzle to clean it, so as to achieve the purpose of dust removal. At the same time, the tea can be turned over by a rotatable baffle. Meanwhile, the tea after cleaning can be air-dried by an exhaust fan.

[0004] However, due to the limitations of its own structure, this structure can often only perform simple blowing dust removal operations on the surface of tea. The overall dust removal wind force is relatively low, and it cannot ensure continuous and stable large-suction dust removal operations. There is a problem that the surface of the tea is not thoroughly cleaned. At the same time, the device cannot perform continuous energy-saving utilization operations on the blowing dust wind force and cannot meet the daily use requirements. Therefore, it is urgent to design a tea processing dust removal device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tea processing dust removal device to solve the problems in the above background technique that due to the limitations of its own structure, the existing structure can often only perform simple blowing dust removal operations on the surface of tea, the overall dust removal wind force is relatively low, it cannot ensure continuous and stable large-suction dust removal operations, there is a problem that the surface of the tea is not thoroughly cleaned, and at the same time, the device cannot perform continuous energy-saving utilization operations on the blowing dust wind force and cannot meet the daily use requirements.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A tea processing dust removal device, including a conveying frame, conveying grooves are opened at both ends of the conveying frame, conveyor belts are arranged at the upper and lower ends of the conveying frame, ventilation holes are evenly opened on the surface of the conveyor belts, and dust removal mesh grooves are arranged at the centers of both sides of the conveying frame;

[0007] Side frames are fixedly connected to both sides of the conveying frame. A sliding frame is movably connected to the side surface of the side frame, and return air ducts are provided at the upper and lower ends of the side frame.

[0008] Preferably, a dust collection box is fixedly connected to the side surface of the sliding frame, and dust separation filter plates are provided at the upper and lower ends of the dust collection box.

[0009] Preferably, ventilation frames are fixedly connected to the upper and lower ends of the conveying frame, and ventilation grooves are formed inside the ventilation frames.

[0010] Preferably, an air distribution grille is provided on the inner bottom wall of the ventilation groove, and return air grilles are provided on both sides of the ventilation frame.

[0011] Preferably, wind diffuser covers are fixedly connected to the upper and lower ends of the conveying frame through the ventilation frames, and ventilation fans are provided at one end of the wind diffuser covers.

[0012] Preferably, feeding port frames are fixedly connected to both ends of the conveying frame, and a feeding limiting rotating plate is provided on the inner wall of one end of the feeding port frame.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] For this tea processing dust removal device, by setting the conveying frame, conveying trough, conveyor belt, ventilation holes, dust discharge mesh trough, ventilation frame, ventilation groove, air distribution grille, wind diffuser cover, ventilation fan, feeding port frame and feeding limiting rotating plate, the device can perform more efficient and continuous tea processing dust removal operations. During actual use, the staff first send the tea raw materials to be processed into the center of the inside of the conveying frame, and then simultaneously start the conveyor belts at the upper and lower ends of the conveying frame to stably convey the tea in the center of the inside of the conveying frame in an up-and-down extrusion manner. During the conveying process, simultaneously start the ventilation fans at one end of the wind diffuser covers at the upper and lower ends to blow air towards the center of the conveying frame. The air flow diffuses along the wind diffuser cover and enters the ventilation frames at the upper and lower ends of the conveying frame, and exits through the air distribution grille in the ventilation groove inside the ventilation frame to perform uniform diversion of the dust removal air flow, so as to form a high-speed dust removal air flow that is synchronized up and down inside the conveying frame. Then, the uniformly stable dust removal air flow can pass through the ventilation holes on the surfaces of the conveyor belts at the upper and lower ends of the conveying frame to perform synchronous tea dust removal operations up and down, and continuously discharge the dust together with the dust removal air flow from the dust discharge mesh troughs on both sides of the conveying frame, so as to achieve more sufficient and continuous dust removal treatment on the surface of the tea, ensure the final quality of the tea, and reflect the practicability of the device design.

[0015] The tea processing dust removal device further improves the overall use effect of the equipment by arranging a conveying frame, a side frame, a pumping frame, a return air duct, a dust collecting box, a dust filter plate, a ventilation frame, a ventilation slot and a return grille. In daily use, when the upper and lower airflows inside the conveying frame are continuously discharged along the dust exhaust mesh slots on both sides of the conveying frame, they can be directly guided into the dust collecting box on the side of the pumping frame, and then the dust inside the airflow is filtered out through the upper and lower dust filter plates. Subsequently, the airflow enters the return air duct at the upper and lower ends of the side frame. The return air duct is connected to the return grilles on both sides of the ventilation frame to directly return the airflow to the ventilation slots of the ventilation frame, and then passes through the uniform air grille to enter the upper and lower ends of the conveying frame for high-speed return of the internal airflow, which greatly improves the effect of the airflow on blowing away dust on the surface of the tea leaves, reflecting the comprehensiveness of the equipment design.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1-4 , an embodiment provided by the utility model:

[0023] A tea processing dust removal device, comprising a conveying rack 1, with conveying grooves 2 opened at both ends of the conveying rack 1. There are conveyor belts 3 arranged at the upper and lower ends of the conveying rack 1. Ventilation holes 4 are evenly opened on the surface of the conveyor belts 3. Dust exhaust net grooves 5 are arranged at the centers on both sides of the conveying rack 1. The upper and lower ends of the conveying rack 1 are fixedly connected with air expansion hoods 15 through ventilation racks 11. One end of the air expansion hood 15 is provided with a ventilation fan 16. Both ends of the conveying rack 1 are fixedly connected with material inlet racks 17. A limiting rotating plate 18 is arranged on the inner wall at one end of the material inlet rack 17. Synchronously start the ventilation fans 16 at one end of the air expansion hoods 15 at the upper and lower ends, so as to perform a blowing operation towards the center of the conveying rack 1. The air flow diffuses along the air expansion hood 15 and enters the ventilation racks 11 at the upper and lower ends of the conveying rack 1, and exits through the uniform air grids 13 in the ventilation grooves 12 inside the ventilation racks 11, performing a uniform diversion operation on the dust removal air flow, so as to form a synchronous high-speed dust removal air flow up and down inside the conveying rack 1.

[0024] Side frames 6 are fixedly connected to both sides of the conveying rack 1. A sliding rack 7 is movably connected to the side surface of the side frame 6. Return air ducts 8 are arranged at the upper and lower ends of the side frame 6. A dust collection box 9 is fixedly connected to the side surface of the sliding rack 7. Dust separation filter plates 10 are arranged at the upper and lower ends of the dust collection box 9. Ventilation racks 11 are fixedly connected to the upper and lower ends of the conveying rack 1. Ventilation grooves 12 are opened inside the ventilation racks 11 shown. Uniform air grids 13 are arranged on the inner bottom wall of the ventilation grooves 12. Return air grids 14 are arranged on both sides of the ventilation rack 11. The dust inside the air flow is filtered through the upper and lower dust separation filter plates 10. Subsequently, the air flow enters the return air ducts 8 at the upper and lower ends of the side frame 6. The return air ducts 8 are connected to the return air grids 14 on both sides of the ventilation rack 11, and directly return the air flow to the ventilation grooves 12 inside the ventilation rack 11.

[0025] Working principle: When in use, the user first feeds the tea raw materials to be processed into the inner center of the conveyor rack 1, and then synchronously starts the conveyor belts 3 at the upper and lower ends of the conveyor rack 1, so that it can perform a stable upward and downward squeezing conveying operation on the tea in the inner center of the conveyor rack 1. During the conveying process, the ventilation fans 16 at one end of the air expansion hoods 15 at the upper and lower ends are synchronously started to blow air toward the center of the conveyor rack 1. The airflow diffuses along the air expansion hoods 15 into the interior of the ventilation racks 11 at the upper and lower ends of the conveyor rack 1, and exits through the uniform air grilles 13 of the ventilation slots 12 inside the ventilation racks 11, and performs a uniform diversion operation of the dust removal airflow, thereby forming a synchronous upward and downward high-speed dust removal airflow inside the conveyor rack 1, and then the uniform and stable dust removal airflow can pass through the ventilation holes 4 on the surfaces of the conveyor belts 3 at the upper and lower ends of the conveyor rack 1 to perform a synchronous upward and downward tea dust removal operation, and remove the dust together with the dust removal air. The airflow is continuously discharged from the dust exhaust mesh grooves 5 on both sides of the conveying frame 1, so as to achieve more sufficient and continuous dust removal treatment on the surface of the tea leaves and ensure the final quality of the tea leaves. In daily use, when the upper and lower airflows inside the conveying frame 1 are continuously discharged along the dust exhaust mesh grooves 5 on both sides of the conveying frame 1, they can be directly guided into the dust collecting box 9 on the side of the pulling frame 7, and then the dust inside the airflow is filtered out through the upper and lower dust filter plates 10. Subsequently, the airflow enters the return air duct 8 at the upper and lower ends of the side frame 6. The return air duct 8 is connected to the return air duct 14 on both sides of the ventilation frame 11, which directly returns the airflow to the ventilation groove 12 of the ventilation frame 11, and then passes through the uniform air grille 13 to enter the upper and lower ends of the conveying frame 1 again, for high-speed reflux of the internal airflow, which greatly improves the effect of the airflow on blowing away the dust on the surface of the tea leaves. The above is the entire working principle of the present invention.
