Description

Technical Field

[0001] The present invention relates to the technical field of grain processing, in particular to a graphene infrared static grain dryer. Background Art

[0002] When the graphene heating film is energized, it generates 8-14μm far-infrared radiation, a wavelength that closely matches the vibration frequency of water molecules in grain. This wavelength can penetrate the grain's surface and directly affect the internal moisture, achieving uniform heating "from the inside out." During the static drying process, the grain is spread flat between multiple layers of graphene radiant plates. The penetrating heating of far-infrared radiation rapidly evaporates the moisture. This achieves high thermal efficiency, low-temperature drying properties, maximizes the preservation of the grain's nutrients, and reduces mechanical damage by eliminating the need for frequent turning. However, to improve drying uniformity, the grain still needs to be turned over without damaging it for optimal drying results.

[0003] A search revealed Chinese patent publication number CN115574545A, which discloses a far-infrared dryer structure and drying method. The structure comprises a storage unit, a drying unit fixedly mounted at the bottom of the storage unit, and a surface of the drying unit with multiple ventilation openings. A lower body is disposed at the bottom of the drying unit, an induced draft fan fixedly mounted on one side of the lower body, and an elevator disposed on the other side of the lower body, the elevator end away from the lower body being connected to the top of the storage unit. While the aforementioned patent improves drying uniformity by repeatedly dropping and lifting the grain, the frequent lifting and dropping can easily cause mechanical damage to the grain, affecting the quality of the final product.

The multiple synchronous wheels are connected by a synchronous belt transmission. The roller is rotatably connected to the lower end of the swing rod. There is a slot at the upper end of the "I"-shaped drive rod, and the roller is rotatably connected to the slot above the drive rod. Flipping component 1 and flipping component 2 are respectively fixedly connected to the bottom of the drive rods on both sides. Two sets of translation slides are fixedly connected to the top of the flipping bracket, and the two sides of the drive rod are slidably connected to the two translation slides.

[0009] Furthermore: the rear side of the flip plate is fixedly connected to a translation pressure plate, and the lower end of the translation pressure plate is rotatably connected to a plurality of rubber rollers.

[0017] 1. The graphene infrared static grain dryer uses two sets of symmetrically installed swing rods to drive the flipping components one and two to perform reciprocating motion in opposite directions. The hollow structure inside the flipping plate cooperates with the air pump to supply air. When moving, the airflow first pushes the grain, and then the triangular boss physically flips it, so that both sides of the grain are evenly heated, reducing mechanical contact damage to the grain, while ensuring that the grain is fully flipped.

[0018] 2. The graphene infrared static grain dryer spreads out the accumulated grains by moving the platen in conjunction with the rubber roller. The subsequent flattening plate further flattens the grain layer. The ventilation holes on the conveyor belt and the bottom fan form an air circulation, and the moist air is forced out, avoiding local overheating or insufficient drying.

[0028] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0029] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1:

[0031] Graphene infrared static grain dryer, such as Figures 1-8 As shown, it includes a conveying support frame 1, one side of the conveying support frame 1 is fixedly connected to an electric roller 2, and the movable ends of multiple electric rollers 2 are transmission-connected to a conveyor belt 3;

[0032] The conveying support frame 1 is fixedly connected to a flipping bracket 10, and the upper end of the flipping bracket 10 is fixedly connected to a flipping drive assembly and an air pump 16. The movable ends on both sides of the flipping drive assembly are respectively fixedly connected to a flipping assembly 1 25 and a flipping assembly 2 26. The air outlet end of the air pump 16 is fixedly connected to an air supply pipe 17, and the other end of the air supply pipe 17 is respectively fixedly connected to the flipping assembly 1 25 and the flipping assembly 2 26;

[0033] The turning drive assembly includes a turning motor 18, a synchronous wheel 19, a synchronous belt 20, a swing rod 21, a roller 22, a driving rod 23 and a translation slide 24. The turning motor 18 is fixedly connected to the top of the turning bracket 10, and one end of the two sets of synchronous wheels 19 and the swing rod 21 are respectively rotatably connected to the turning bracket 10. The swing rod 21 is fixedly connected to the lower end of the synchronous wheel 19 at one time. One side of the synchronous wheel 19 is fixedly connected to the power output end of the turning motor 18. The multiple synchronous wheels 19 are connected by a synchronous belt 20. The roller 22 is rotatably connected to the lower end of the swing rod 21. The upper end of the "I"-shaped driving rod 23 has a slot, and the roller 22 is rotatably connected to the slot above the driving rod 23. The turning component 1 25 and the turning component 2 26 are respectively fixedly connected to the bottom of the driving rods 23 on both sides. The two sets of translation slides 24 are fixedly connected to the top of the turning bracket 10, and the two sides of the driving rod 23 are slidably connected to the two translation slides 24;

[0034] The flip assembly 1 25 and the flip assembly 2 26 include a flip plate 27, a triangular boss 28 and an air blowing groove 29. The multiple flip plates 27 are fixedly connected to the lower movable end of the flip drive assembly, and the triangular boss 28 is fixedly connected to the bottom of the flip plate 27. The inside of the flip plate 27 and the triangular boss 28 is hollow. A plurality of air blowing grooves 29 are opened on both sides of the triangular boss 28. The air inlet end of the flip plate 27 is fixedly connected to the air outlet end of the air supply pipe 17. The installation angles of the flip plates 27 inside the flip assembly 1 25 and the flip assembly 2 26 are mirror-symmetrical.

[0035] When the device is in use, the grain is placed on one end of the conveying support frame 1, and then the electric roller 2 is started, which can drive the conveyor belt 3 to move and transport the grain to the other end. There are multiple openings on the conveyor belt 3 with a diameter smaller than the grain to be transported for air to pass through;

[0036] During the grain movement process, the turning motor 18 is started, which in turn drives the two synchronous wheels 19 to rotate simultaneously, and then drives the two swing arms 21 to rotate, so that the roller 22 below makes use of the slot above the drive rod 23 to move the drive rod 23 left and right when performing a circular motion. At this time, the drive rods 23 on both sides can simultaneously drive the turning assembly 1 25 and the turning assembly 2 26 below to move back and forth. Because the two swing arms 21 are installed at opposite angles, the turning assembly 1 25 and the turning assembly 2 26 move in opposite directions when reciprocating.

[0037] When the flipping assembly 1 25 and the flipping assembly 2 26 move back and forth, the air pump 16 will supply air to the multiple flipping plates 27 through the air supply pipe 17, so that before the flipping plates 27 move to contact the grains, the grains can be pushed by the airflow to move the grains. At the same time, the bottom of the flipping plate 27 fits the conveyor belt 3, and the triangular boss 28 can push the grains that are not blown by the airflow to rotate from the bottom. In this way, the grains can be rotated and turned over while minimizing direct contact with the grains, which not only improves the uniformity of drying but also prevents the grains from being mechanically damaged.

[0038] like Figures 1-8 As shown, the rear side of the flip plate 27 is fixedly connected to a translation pressing plate 30, and the lower end of the translation pressing plate 30 is rotatably connected to a plurality of rubber rollers 32;

[0039] When the grains are pushed by the multiple flip plates 27, the grains will be stacked together. During the movement of these stacked grains, the translation pressing plates 30 moving on both sides will cooperate with the rubber roller 32 to move repeatedly, flattening the stacked grains to achieve better subsequent drying effects.

[0040] like Figures 1-8 As shown, side guard plates 4 are fixedly connected to the top of the conveying support frame 1 on both sides, and a discharge chute 5 is fixedly connected to one side of the side guard plate 4. The side guard plates 4 can prevent the grains from falling from both sides when conveying the grains, and the discharge chute 5 can allow the grains to be evenly spread on the conveyor belt 3.

[0041] like Figures 1-8 As shown, one side of the conveying support frame 1 is fixedly connected to a drying distance adjustment component, one end of the drying distance adjustment component is respectively fixedly connected to a graphene infrared generator 1 7 and a graphene infrared generator 2 8, and one side of the graphene infrared generator 2 8 is slidably connected to the conveying support frame 1;

[0042] Graphene infrared generator 1 7 and graphene infrared generator 2 8 are located on the upper and lower sides of the grains, and can emit far infrared rays to evenly dry the grains after being powered on;

[0043] The drying distance adjustment assembly includes an opening and closing bracket 11, a lifting bracket 12, a sliding rod 13, a double-headed screw 14 and an opening and closing motor 15. One end of the opening and closing bracket 11 is fixedly connected to the conveying support frame 1 on one side, and multiple sliding rods 13 are fixedly connected to the inner side of the opening and closing bracket 11. One end of the opening and closing motor 15 is fixedly connected to the bottom of the opening and closing bracket 11. The double-headed screw 14 is fixedly connected to the power output end of the opening and closing motor 15. The lifting brackets 12 on both sides are threadedly connected to the two ends of the double-headed screw 14. The two sides of the lifting bracket 12 are slidably connected to the sliding rod 13. The graphene infrared generator 1 7 and the graphene infrared generator 2 8 are respectively fixedly connected to the upper and lower lifting brackets 12;

[0044] The opening and closing motor 15 can drive the double-headed screw 14 to rotate, thereby adjusting the distance between the graphene infrared generator 1 7 and the graphene infrared generator 2 8 relative to the grains, thereby achieving the effect of regulating the intensity of the far infrared rays.

[0045] When the device is in use, the grain is placed on one end of the conveying support frame 1, and then the electric roller 2 is started, which can drive the conveyor belt 3 to move and transport the grain to the other end. There are multiple openings on the conveyor belt 3 with a diameter smaller than the grain to be transported, which can be used for air to pass through.

[0046] During the grain movement process, the turning motor 18 is started, which in turn drives the two synchronous wheels 19 to rotate simultaneously, and then drives the two swing arms 21 to rotate, so that the roller 22 below makes use of the slot above the drive rod 23 to move the drive rod 23 left and right when performing a circular motion. At this time, the drive rods 23 on both sides can simultaneously drive the turning assembly 1 25 and the turning assembly 2 26 below to move back and forth. Because the two swing arms 21 are installed at opposite angles, the turning assembly 1 25 and the turning assembly 2 26 move in opposite directions when reciprocating.

[0047] When the turning assembly 1 25 and the turning assembly 2 26 move back and forth, the air pump 16 supplies air to the multiple turning plates 27 through the air supply pipe 17. In this way, before the turning plates 27 move to contact the grains, the air flow can push the grains to move. At the same time, the bottom of the turning plates 27 is in contact with the conveyor belt 3, and the triangular boss 28 can push the grains that are not blown by the air flow to rotate from below. In this way, the grains can be rotated and turned over while minimizing direct contact with the grains, thereby improving the uniformity of drying and preventing the grains from being mechanically damaged.

[0048] When the grains are pushed by the multiple flip plates 27, the grains will be stacked together. During the movement of these stacked grains, the translation pressing plates 30 moving on both sides cooperate with the rubber rollers 32 to move repeatedly, flattening the stacked grains, so that the subsequent drying effect is better.

[0049] The side guard plates 4 can prevent the grains from falling from both sides when conveying the grains. The feed chute 5 can evenly distribute the grains onto the conveyor belt 3. The graphene infrared generator 1 7 and the graphene infrared generator 2 8 are located on the upper and lower sides of the grains. They can emit far infrared rays to evenly dry the grains after being powered on.

[0050] The opening and closing motor 15 can drive the double-headed screw 14 to rotate, thereby adjusting the distance between the graphene infrared generator 1 7 and the graphene infrared generator 2 8 relative to the grains, thereby achieving the effect of regulating the intensity of the far infrared rays.

[0051] Example 2:

[0052] Graphene infrared static grain dryer, such as Figures 1-8As shown, the inner side of the side guard plate 4 is fixedly connected to a plurality of flattening pressing plates 1 6 and 2 flattening pressing plates 31, and one side of the translation pressing plate 30 is slidably connected to the lower side of the flattening pressing plate 2 31; the flattening pressing plate 1 6 can quickly flatten the grains poured from the feed chute 5 onto the conveyor belt 3, reducing the grain stacking thickness and making the drying more uniform;

[0053] The second flattening plate 31 can further flatten the grains moved by the translation plate 30 .

[0054] like Figures 1-8 As shown, a plurality of ventilation components 9 are fixedly connected to the bottom of the conveying support frame 1. The ventilation components 9 are fans that can slowly blow air upward from the bottom to discharge the moist gas and improve the drying effect.

[0055] The above is a preferred specific embodiment of the present invention, and the scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions and improvements made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with existing technologies or public common sense, within the spirit and principles of the present invention, should be covered by the scope of protection of the present invention.
