Description
Technical Field
[0001] This utility model relates to the field of hulled sesame technology, and in particular to a separation device for removing impurities from hulled sesame seeds. Background Technology
[0002] Sesame, belonging to the Pedaliaceae family, is the seed of the sesame plant, found throughout tropical regions worldwide. Sesame is one of my country's four major edible oil crops and a leading oilseed crop in the country. Sesame products have high application value; its seeds contain up to 61% oil. my country has a long history of using sesame and sesame oil to make many famous and unique foods, renowned worldwide. After harvesting, sesame seeds need to be hulled to become hulled sesame seeds.
[0003] Currently, in the industrial processing of hulled sesame seeds, industrial equipment is used to separate the sesame seed coat from the sesame fruit, resulting in a mixture of husk and sesame seeds. Separation of the husk and sesame seed is necessary. However, in actual production, some husks tend to adhere to the sesame seed surface due to adhesion. Traditional separation methods, such as simple airflow, are insufficient to effectively break the bond between the two, leading to impurities and incomplete separation. Furthermore, simple airflow is usually unidirectional, and some husks do not receive sufficient force. After separation from the sesame seed, the insufficient separation distance causes them to re-mix into the sesame seed, resulting in low separation efficiency and repeated rework. Utility Model Content
[0004] To solve the above problems, this utility model provides a separation device for removing impurities from hulled sesame seeds.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a separating device for shelling and removing impurities from sesame seeds, comprising a frame, a square tube vertically arranged on the frame, a hopper at the top of the square tube, a discharge pipe connected to the bottom of the hopper, an installation frame arranged below the hopper inside the square tube, a conveying auger horizontally arranged on the installation frame, the inlet of the conveying auger connected to the lower end of the discharge pipe, a rotating shaft horizontally rotatably arranged inside the square tube below the discharge outlet of the conveying auger, a plurality of striking plates circumferentially spaced on the rotating shaft, an air inlet opened on one side of the middle section of the square tube, an air intake component for blowing air into the square tube arranged on the outer wall of the square tube at the air inlet, a collection port opened on the tube wall of the square tube opposite to the air inlet, and an air extraction and collection component arranged on the outer wall of the square tube at the collection port.
[0006] By adopting the above technical solution, an installation frame, a hopper, a conveying auger, a striking plate, an air intake assembly, and an air extraction and collection assembly are set up. The hopper stores hulled sesame seeds, and the conveying auger transports the hulled sesame seeds from the auger's outlet. The hulled sesame seeds fall from the auger's outlet through a rotating shaft. The striking plate rotates around the shaft axis, striking the hulled sesame seeds falling from the auger's outlet. At the moment of contact between the striking plate and the hulled sesame seeds, high-frequency vibrations are generated on the sesame seed surface. This vibration breaks the adhesion between the husk and the sesame seeds, loosening and separating the husk that was originally attached to the sesame seeds, ensuring easy separation of the husk subsequently. Air is blown into a square tube through the air intake assembly, utilizing the difference in forces experienced by different objects in the airflow for separation. Because the husk is lightweight and has a large windward area, it is carried by the airflow and blown towards the collection port; while the sesame seeds, with their relatively large mass, are not significantly deflected by the airflow and continue to fall. The air collection component draws air from the square tube to the collection port, which in turn moves the shell and coating into the collection port, ensuring effective collection and high separation efficiency.
[0007] Furthermore, the air intake assembly includes a fixed frame disposed on the outer wall of the square tube, on which an air intake pipe and a blower are disposed. One end of the air intake pipe is connected to the air intake port, and the other end is connected to the air outlet of the blower.
[0008] By adopting the above technical solution, a fixed frame, an air intake pipe, and a blower are set up. The blower blows outside air into the air intake pipe, and then into the square pipe.
[0009] Furthermore, the air intake pipe is arranged at an angle, with one end of the air intake pipe connected to the air inlet being higher than the end connected to the blower.
[0010] Furthermore, the air extraction and collection assembly includes a collection box and an installation frame. The collection box is disposed on the outer wall of the square tube and one side of the collection box is connected to the collection port. Protrusions are provided on opposite side walls inside the collection box. The bottom surface of the installation frame is slidably connected to the top surface of the two protrusions. A collection mesh cover is provided inside the installation frame.
[0011] By adopting the above technical solution, a collection box, a mounting frame, and protrusions are set up, and the shell that passes through the collection port falls into the collection net and is collected.
[0012] Furthermore, a door is hinged to one side of the collection box, an air extraction port is provided at the bottom of the collection box, and an air pump is provided on the outer wall of the square tube, with the air inlet pipe of the air pump connected to the air extraction port.
[0013] By adopting the above technical solution, a box door, an air extraction port, and an air extraction pump are set up. The air extraction pump draws air from the collection box, causing the air in the square tube to flow towards the collection port, thereby driving the shell to move into the collection port.
[0014] Furthermore, a guide hopper is provided inside the square tube on the lower side of the rotating shaft, and the lower port of the guide hopper is close to the air inlet.
[0015] By adopting the above technical solution, a guide hopper and an air inlet are set up. The shelled sesame seeds that have been patted fall into the guide hopper and are then discharged from the lower end of the guide hopper. The lower end of the guide hopper is close to the air inlet, which makes the airflow sprayed from the air inlet have a better effect on separating the shell.
[0016] Furthermore, a drive motor is horizontally arranged on the outer wall of the square tube, and the output shaft of the drive motor is connected to the rotation shaft.
[0017] By adopting the above technical solution, a drive motor is horizontally installed on the outer wall of the square tube. The drive motor drives the rotating shaft to rotate, thereby causing several striking plates to rotate.
[0018] In summary, this utility model has the following beneficial effects: This application includes an installation frame, a hopper, a conveying auger, a striking plate, an air intake assembly, and an air extraction and collection assembly. The hopper stores shelled sesame seeds, and the conveying auger transports the shelled sesame seeds from the hopper. The shelled sesame seeds fall from the outlet of the conveying auger. The rotating shaft drives the striking plate to rotate around the axis of the rotating shaft, striking the shelled sesame seeds falling from the outlet of the conveying auger. At the moment of contact between the striking plate and the shelled sesame seeds, high-frequency vibration is generated on the surface of the sesame seeds. This vibration breaks the adhesion between the shell and the sesame seeds, causing the shell that was originally attached to the sesame seeds to loosen and separate, ensuring easy separation of the shell later. Air is blown into the square tube by the air intake assembly, utilizing the difference in the forces acting on different objects in the airflow for separation. Because the shell is lightweight and has a large windward area, it is carried by the airflow and blown towards the collection port; while the sesame seeds, with their relatively large mass, are not significantly deflected by the airflow force and continue to fall. The air collection component draws air from the square tube to the collection port, which in turn moves the shell and coating into the collection port, ensuring effective collection and high separation efficiency.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0024] like Figure 1-3As shown in the figure, this application discloses a separation device for removing impurities from shelled sesame seeds, including a frame 10, a hopper 12, a conveying auger 21, an air inlet assembly 40, and an air extraction and collection assembly 50. A square tube 11 is vertically arranged on the frame 10. The hopper 12 is located at the top of the square tube 11 and is used to store shelled sesame seeds. A discharge pipe 13 is connected to the bottom of the hopper 12. A mounting frame 20 is arranged inside the square tube 11 below the hopper 12. The conveying auger 21 is horizontally arranged on the mounting frame 20. The inlet of the conveying auger 21 is connected to the lower end of the discharge pipe 13. The conveying auger 21 conveys the shelled sesame seeds in the hopper 12 to ensure a uniform discharge speed. A rotating shaft 30 is horizontally rotatably arranged inside the square tube 11 below the discharge port of the conveying auger 21. The length direction of the rotating shaft 30 is perpendicular to the length direction of the conveying auger 21. A number of striking plates 31 are circumferentially spaced on the rotating shaft 30. An air inlet 14 is located on one side of the middle section of the square tube 11. An air intake assembly 40 is located on the outer wall of the square tube 11 at the air inlet 14, used to blow air into the square tube 11. A collection port 15 is located on the tube wall of the square tube 11 opposite the air inlet 14. An air extraction and collection assembly 50 is located on the outer wall of the square tube 11 at the collection port 15. Hulled sesame seeds fall from the outlet of the conveying auger 21. The rotating shaft 30 drives the striking plates 31 to rotate around the axis of the rotating shaft 30, striking the hulled sesame seeds falling from the outlet of the conveying auger 21. At the moment of contact between the striking plates 31 and the hulled sesame seeds, high-frequency vibrations are generated on the surface of the sesame seeds. This vibration breaks the adhesion between the husk and the sesame seeds, loosening and separating the husk that was originally attached to the sesame seeds, ensuring easy separation later. Air is blown into the square tube 11 by the air intake assembly 40, utilizing the difference in forces experienced by different objects in the airflow for separation. Because the shell is lightweight and has a large windward surface area, it is carried by the airflow and blown towards the collection port 15. Sesame seeds, on the other hand, are relatively heavy, and the airflow force is insufficient to cause them to deviate significantly, maintaining their downward trend. The suction collection component 50 directs air from the square tube 11 towards the collection port 15, thereby moving the shell into the collection port 15, ensuring effective collection and high separation efficiency. The conveying auger 21, also known as a tubular screw conveyor, uses a motor to drive the screw to rotate, pushing the material for conveying.
[0025] Specifically, the air intake assembly 40 includes a mounting bracket 41 disposed on the outer wall of the square tube 11. The mounting bracket 41 is equipped with an air intake pipe 42 and a blower 43. One end of the air intake pipe 42 is connected to the air inlet, and the other end is connected to the air outlet of the blower 43. Outside air is blown into the air intake pipe 42 by the blower 43 and then into the square tube 11. The air intake pipe 42 is arranged at an angle, with the end connected to the air inlet higher than the end connected to the blower 43, causing the airflow to enter the square tube 11 at an upward angle. This arrangement, while maintaining the same flow rate, effectively reduces the horizontal force exerted by the airflow on the sesame seeds. Compared to a horizontal air intake method, it significantly reduces the lateral displacement of the sesame seeds caused by the airflow impact, ensuring that the sesame seeds fall along a predetermined path and preventing them from being accidentally drawn into the collection port 15, thereby further improving the accuracy and efficiency of impurity removal and separation.
[0026] During setup, the air extraction and collection assembly 50 includes a collection box 51 and a mounting frame 52. The collection box 51 is mounted on the outer wall of the square tube 11, and one side of the collection box 51 is connected to the collection port 15. Protrusions 53 are provided on opposite side walls inside the collection box 51. The bottom surface of the mounting frame 52 is slidably connected to the top surface of the two protrusions 53. A collection mesh cover 54 is installed inside the mounting frame 52. Shells passing through the collection port 15 fall into the collection mesh cover 54 and are collected. A door 55 is hinged to one side of the collection box 51, and an air extraction port 56 is opened at the bottom of the collection box 51. An air extraction pump 57 is installed on the outer wall of the square tube 11. The air inlet pipe 42 of the air extraction pump 57 is connected to the air extraction port 56. The air extraction pump 57 continuously extracts air from the collection box 51, forming a directional airflow channel between the square tube 11 and the collection box 51. This causes the blown-up shells to be precisely pushed to the collection port 15 by the airflow, significantly improving the thoroughness of shell collection. During cleaning, simply open the hinged door 55 and slide the mounting frame 52 along the protrusion 53 to easily remove it. This simplifies the cleaning process of the inner shell of the collection net cover 54, effectively reduces manual maintenance time and operational difficulty, and improves the ease of use of the equipment.
[0027] In the specific setup, a guide hopper 16 is located inside the square tube 11, below the rotating shaft 30. The lower end of the guide hopper 16 is near the air inlet. The shelled sesame seeds, after being tapped, slide into the guide hopper 16 and are then discharged from the lower end after being guided by the guide hopper 16. This ensures that the shelled sesame seeds come into contact with the airflow from the air inlet, resulting in better separation of the shells. A drive motor 32 is horizontally mounted on the outer wall of the square tube 11. The output shaft of the drive motor 32 is connected to the rotating shaft 30, driving the rotating shaft 30 to rotate, which in turn drives several tapping plates 31 to rotate.
[0028] The working principle of the sesame seed shelling and impurity removal separation device in this embodiment is as follows: The conveying auger 21 conveys the shelled sesame seeds in the hopper 12, and the shelled sesame seeds fall from the discharge port of the conveying auger 21. The drive motor 32 is started to drive the rotating shaft 30 to rotate, which drives several striking plates 31 to rotate around the axis of the rotating shaft 30, striking the shelled sesame seeds falling from the discharge port of the conveying auger 21, so that the shells originally attached to the sesame seeds are loosened and separated. The blower 43 blows outside air into the air inlet pipe 42, and then rushes into the square pipe 11 and sprays out from the air inlet. The air pump 57 draws air from the collection box 51, so that the air in the square pipe 11 flows towards the collection port 15, so that the shells in the mixture of shells and sesame seeds during the falling process pass through the collection port 15 and reach the collection screen 54 under the action of airflow.
[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
