Description

Technical Field

[0001] This utility model relates to the field of grain processing technology, and in particular to a graphene infrared static grain dryer. Background Technology

[0002] The 8-14μm far-infrared rays generated by the graphene electrothermal film after being energized are highly matched with the vibration frequency of water molecules in grains. This allows the far-infrared rays to penetrate the surface of the grains and directly act on the internal moisture, achieving uniform heating "from the inside out." During the static drying process, the grains are spread flat between multiple layers of graphene radiant plates. The penetrating heating of the far-infrared rays causes the moisture to evaporate rapidly. This method achieves high thermal efficiency, low-temperature drying characteristics that maximize the preservation of nutrients in the grains, and reduces mechanical damage to the grains by eliminating the need for frequent turning. However, to improve the uniformity of drying, the grains still need to be turned over without damaging them for better drying results.

[0003] A search revealed Chinese patent publication number CN115574545A, which discloses a far-infrared dryer structure and its drying method. The dryer includes a storage section, with a drying section fixedly installed at its bottom. Multiple ventilation openings are provided on the surface of the drying section. A lower body is located at the bottom of the drying section, with a blower fixedly installed on one side and a lifting mechanism on the other side. The end of the lifting mechanism furthest from the lower body is connected to the top of the storage section. While this patent improves the uniformity of drying 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.

Multiple synchronous pulleys are connected to each other through synchronous belt transmission. The rollers are rotatably connected to the lower end of the swing rod. The upper end of the "I"-shaped drive rod has a slot. The rollers are rotatably connected to the slot above the drive rod. Turning assembly one and turning assembly two are fixedly connected to the lower part of the two drive rods on both sides. Two sets of translation slide rails are fixedly connected to the top of the turning bracket. The two sides of the drive rod are slidably connected to the two translation slide rails.

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

[0017] 1. The graphene infrared static grain dryer uses two sets of symmetrically installed swing rods to drive the turning components one and two to reciprocate in opposite directions. The hollow structure inside the turning plate, combined with the air pump supply, first pushes the grain through the airflow during movement, and then physically turns it through the triangular protrusions, so as to achieve uniform heating on both sides of the grain, reduce mechanical contact damage to the grain, and ensure that the grain is fully turned.

[0018] 2. The graphene infrared static grain dryer uses a sliding pressure plate and rubber rollers to spread out the accumulated grains during the movement process. A subsequent flattening pressure plate further flattens the grain layer. The ventilation holes on the conveyor belt and the bottom fan form an airflow circulation, forcibly expelling humid air and avoiding local overheating or insufficient drying.

[0028] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0029] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0030] Example 1:

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

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

[0033] The turning drive assembly includes a turning motor 18, a synchronous pulley 19, a synchronous belt 20, a swing rod 21, a roller 22, a drive rod 23, and a translation slide rail 24. The turning motor 18 is fixedly connected to the top of the turning bracket 10. One end of each of the two sets of synchronous pulleys 19 and the swing rod 21 is rotatably connected to the turning bracket 10. The swing rod 21 is fixedly connected to the lower end of the synchronous pulley 19. One side of the synchronous pulley 19 is fixedly connected to the power output end of the turning motor 18. Multiple synchronous pulleys 19 are connected to each other through the 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 drive rod 23 has a slot. The roller 22 is rotatably connected to the slot above the drive rod 23. Turning assembly one 25 and turning assembly two 26 are fixedly connected to the lower part of the two drive rods 23 respectively. Two sets of translation slide rails 24 are fixedly connected to the top of the turning bracket 10. The two sides of the drive rod 23 are slidably connected to the two translation slide rails 24.

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

[0035] When the device is in use, grain is placed on one end of the conveyor support frame 1, and then the electric roller 2 is started, which drives 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 being transported, which can be used to allow air to pass through.

[0036] During the movement of the grain, the turning motor 18 is started, which drives the two synchronous wheels 19 to rotate simultaneously, which in turn drives the two swing rods 21 to rotate. When the roller 22 below makes a circular motion, it uses the slot above the drive rod 23 to move the drive rod 23 left and right. At this time, the drive rods 23 on both sides can simultaneously drive the turning component 1 25 and turning component 26 below to move back and forth. Since the two swing rods 21 are installed at opposite angles, the turning component 1 25 and turning component 26 move in opposite directions when moving back and forth.

[0037] As the first and second turning components 25 and 26 reciprocate, the air pump 16 supplies air to the multiple turning plates 27 through the air supply pipe 17. This allows the grains to be pushed by the airflow before the turning plates 27 come into contact with them. At the same time, the bottom of the turning plate 27 is attached to the conveyor belt 3, and the triangular protrusion 28 can push the grains that are not blown by the airflow from below to rotate. This allows the grains to rotate and turn over while minimizing direct contact with them, which improves the uniformity of drying and prevents the grains from being mechanically damaged.

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

[0039] When the grains are pushed by multiple flipping plates 27, they will stack together. As these stacked grains move, they will be flattened by the moving translation plates 30 on both sides in conjunction with the rubber roller shaft 32, which will make the stacked grains better for subsequent drying.

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

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

[0042] The graphene infrared generator 1 (7) and the graphene infrared generator 2 (8) are located on the top and bottom sides of the grain, and can emit far-infrared rays to dry the grain evenly after being powered on.

[0043] The drying distance adjustment assembly includes an opening and closing bracket 11, a lifting bracket 12, a slide 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 a side conveying support frame 1. Multiple slide rods 13 are fixedly connected to the inside 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 two lifting brackets 12 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 slide rod 13. Graphene infrared generator 7 and graphene infrared generator 8 are fixedly connected to the upper and lower lifting brackets 12 respectively.

[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 17 and the graphene infrared generator 28 relative to the grain, and thus controlling the intensity of far-infrared rays.

[0045] In this embodiment, when the device is in use, grains are placed on one end of the conveyor support frame 1, and then the electric roller 2 is started, which drives the conveyor belt 3 to move and transport the grains to the other end. There are multiple openings on the conveyor belt 3 with a diameter smaller than the grains being transported, which can be used to allow air to pass through.

[0046] During the movement of the grain, the turning motor 18 is started, which drives the two synchronous wheels 19 to rotate simultaneously, which in turn drives the two swing rods 21 to rotate. When the roller 22 below makes a circular motion, it uses the slot above the drive rod 23 to move the drive rod 23 left and right. At this time, the drive rods 23 on both sides can simultaneously drive the turning component 1 25 and turning component 26 below to move back and forth. Since the two swing rods 21 are installed at opposite angles, the turning component 1 25 and turning component 26 move in opposite directions when moving back and forth.

[0047] When the first turning component 25 and the second turning component 26 reciprocate, the air pump 16 supplies air to the multiple turning plates 27 through the air supply pipe 17. This allows the grains to be pushed by the airflow before the turning plates 27 come into contact with the grains. At the same time, the bottom of the turning plate 27 is attached to the conveyor belt 3, and the triangular protrusion 28 can push the grains that are not blown by the airflow from below to rotate. This allows the grains to rotate and turn over while minimizing direct contact with them, which improves the uniformity of drying and prevents the grains from being mechanically damaged.

[0048] When the grains are pushed by multiple flipping plates 27, they will stack together. During the movement of these stacked grains, they will be flattened by the moving translation plates 30 on both sides in conjunction with the rubber roller shaft 32, which will make the stacked grains better in the subsequent drying process.

[0049] The side guard plate 4 can prevent the grain from falling from both sides when the grain is being transported. The feed chute 5 can spread the grain evenly on 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 grain and can emit far-infrared rays to dry the grain evenly 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 17 and the graphene infrared generator 28 relative to the grain, and thus controlling the intensity of far-infrared rays.

[0051] Example 2:

[0052] Graphene infrared static grain dryer, such as Figures 1-8As shown, multiple flattening pressure plates 6 and 31 are fixedly connected to the inner side of the side guard plate 4. The translation pressure plate 30 is slidably connected to the bottom of the flattening pressure plate 31. The flattening pressure plate 6 can quickly flatten the grains poured from the feeding chute 5 onto the conveyor belt 3, reducing the thickness of the grain stack and making the drying more uniform.

[0053] The flattening plate 2 31 can further flatten the grains that have been moved by the shifting plate 30.

[0054] like Figures 1-8 As shown, the bottom of the conveyor support frame 1 is fixedly connected with multiple ventilation components 9. The ventilation components 9 are fans, which can slowly blow airflow from below to allow the humid gas to be discharged and improve the drying effect.

[0055] The above description represents a preferred embodiment of this utility model. The scope of protection of this utility model is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in this utility model, combined with existing technology or common sense, and within the spirit and principles of this utility model, should be covered within the scope of protection of this utility model.
