[0055] The present application will be described in detail below through examples.
[0056] In agricultural production, crops such as corn, rice, and wheat contain a large amount of moisture, making them unsuitable for winter storage and transportation, and prone to spoilage. Traditional methods involve sun-drying to remove moisture, but this method is inefficient, highly dependent on environmental conditions, and unsuitable for large-scale production, and is gradually being replaced by large-scale drying equipment.
[0057] Existing crop drying equipment is prone to condensation during drying in cold climates such as those in Northeast my country, resulting in poor drying performance.
[0058] To address the technical problems existing in current agricultural equipment, this application proposes an electromagnetic heating drying device and system to solve at least one of the technical problems mentioned in the background art. The electromagnetic heating drying device includes: a drying cylinder having a first end and a second end along its length; a first feed inlet on the upper surface of the first end and a first discharge outlet on the lower surface of the second end; a heating device for providing heat to the interior of the drying cylinder; a feeding screw disposed inside the drying cylinder for outputting material from the first feed inlet to the first discharge outlet; and a power mechanism connected to the feeding screw and providing power to it; wherein the drying cylinder has an air inlet along its length, and an air inlet is connected to the interior of the drying cylinder through the air inlet.
[0059] According to this invention concept, by opening holes in the drying drum and adding an exhaust fan, the hot air inside the drying drum can be discharged in a timely manner, preventing the hot air from condensing and forming condensate inside the drying drum, thus achieving the technical effect of improving drying efficiency.
[0060] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0061] Based on the inventive concept of this application, in some preferred embodiments of this application, an electromagnetic heating drying device is provided, comprising:
[0062] A drying cylinder 10 has a first end 101 and a second end 102 along its length. The upper surface of the first end of the drying cylinder 10 has a first feed inlet 103, and the lower surface of the second end 102 has a first discharge outlet 104. The material to be dried enters the drying cylinder 10 through the first feed inlet 103, is dried inside, and then exits the drying cylinder 10. In some preferred embodiments, a guide plate 1041 is provided below the first discharge outlet 104, extending from the first end 101 towards the second end 102 to prevent material leakage at the first discharge outlet 104.
[0063] A heating device is provided to provide heat to the interior of the drying drum 10. In some embodiments, the heating device is a device that generates heat using electromagnetic heating and dehydrates the material to be dried. Compared with the traditional method of heating with circulating water, electromagnetic heating consumes less energy and simplifies the construction of the device.
[0064] The feeding screw 20 is disposed inside the drying cylinder 10 and is used to output the material from the first feed port 103 to the first discharge port 104. The drying equipment also includes a power mechanism, which is connected to the feeding screw 20 and outputs power to it, so that the feeding screw 20 rotates, thereby driving the material to be dried to move inside the drying cylinder 10.
[0065] In some embodiments, the drying cylinder 10 is provided with an air inlet 105 in its length direction, and the air inlet device 106 is connected to the interior of the drying cylinder 10 through the air inlet 105.
[0066] By adopting the above technical solution, by opening holes in the drying drum and adding an exhaust fan, the hot air inside the drying drum can be discharged in a timely manner, preventing the hot air from condensing into condensate inside the drying drum, thus achieving the technical effect of improving drying efficiency.
[0067] In some preferred embodiments, multiple air inlets 105 are spaced apart on the upper surface of the drying cylinder 10, and each air inlet 105 corresponds to one air-driving device 106. Since the drying cylinder 10 is relatively long, providing multiple air inlets allows for more efficient exhaust of hot and humid air from the drying cylinder, improving the drying effect. Specifically, each air-driving device can be controlled individually, facilitating more precise adjustment of the airflow.
[0068] In some preferred embodiments, the drying cylinder 10 includes, from the inside out, an inner cylinder layer 111, a heat insulation layer 112, an insulating layer 113, an electromagnetic heating wire 114, and a protective layer 115. By energizing the electromagnetic heating wire 114, the inner cylinder layer and the feeding screw are heated, thereby drying the material. The inner cylinder layer and the feeding screw are made of stainless steel or Cr stainless steel, as these materials have superior heating performance. In some embodiments, the electromagnetic heating wire 114 is electrically connected to the distribution box 30 outside the drying cylinder, and the magnetic field generated by the electromagnetic heating wire 114 heats the inner cylinder layer 111 using electromagnetic heating technology known to those skilled in the art.
[0069] In some preferred embodiments, multiple distribution boxes 30 are fixedly arranged at intervals on one side of the support frame 50 to facilitate equipment control and transportation. Furthermore, this application also includes a control box 90 for controlling the power supply to the distribution boxes 30, which, in conjunction with the temperature sensor 40, enables automatic temperature control of the interior temperature of the drying drum 10.
[0070] In some embodiments, the insulation layer 112 is selected from materials such as silicate, polyurethane foam or rock wool, and is used to maintain the temperature inside the drying cylinder.
[0071] In some embodiments, the insulating layer 113 may be selected from one or more of polytetrafluoroethylene (PTFE), polyurethane (PU) or polyimide (PI) and used to insulate the electromagnetic heating wire 114.
[0072] In some embodiments, the protective layer 115 may be a glass fiber layer, used to prevent external impacts from damaging the electromagnetic heating wire 114 and to ensure the stability of heating inside the drying drum.
[0073] In some preferred embodiments, a temperature sensor 40 is provided inside the drying cylinder 10, and at least a portion of the temperature sensor 40 is embedded in the insulating layer 113. Furthermore, one end of the temperature sensor 40 is embedded in the insulating layer 113, and the other end is embedded in the heat insulation layer 112, for detecting the temperature inside the drying cylinder 10, thereby providing a basis for the user to adjust the drying temperature, while preventing the temperature sensor from being heated by the inner cylinder layer, thus avoiding damage to the equipment.
[0074] In some preferred embodiments, the electromagnetic heating drying equipment includes a support frame 50, on which the drying cylinder is mounted, such that the first end of the drying cylinder is lower than the second end.
[0075] In some embodiments, the support frame 50 has a motor support frame 501 on the side near the first end 101, and the power of the feeding screw 20 comes from the motor 107, which is fixedly connected to the motor support frame 501. By adopting the above solution, placing the motor near the first end can reduce the cable length and lower the center of gravity of the overall equipment, making the equipment more stable.
[0076] In some preferred embodiments, the drying equipment further includes a feeder 60 for feeding the material to be dried into the first feed inlet 103. Further, a carrier frame 70 is connected to the support frame 50 near its first end. The carrier frame 70 includes a first frame 701 and a second frame 702 arranged at an angle to each other. The feeder 60 is mounted on the carrier frame 70 and simultaneously abuts against both the first frame 701 and the second frame 702. More preferably, the first frame 701 is vertically arranged, and the second frame 702 is horizontally arranged, with the two being perpendicular to each other.
[0077] In some preferred embodiments, the support frame 70 further includes a third frame 703 arranged at an angle to the second frame 702. One end of the third frame 703 is connected to the second frame 702, and the other end extends away from the first frame 701, thereby providing a positioning effect for the loading machine on the support frame and preventing it from sliding on the support frame.
[0078] In some preferred embodiments, the feeder 60 includes a material cylinder 601, a second feed inlet 602 located at the lower end of the material cylinder 601, and a second discharge outlet 603 located at the upper end of the material cylinder 601.
[0079] In some preferred embodiments, a sleeve 80 is provided on the outside of the drying cylinder 10. The sleeve 80 is mounted on the support frame 50 and covers the outside of the drying cylinder 10 to protect the inside of the drying cylinder 10 from external environmental contamination. Furthermore, the sleeve 80 is made of a non-electromagnetic heating material, such as stainless steel, polyethylene (PE), polypropylene (PP), or polyamide (PA). This non-electromagnetic heating material does not heat up when the electromagnetic heating wire is energized. Using a non-heating material prevents the sleeve 80 from heating up during equipment operation, reducing the risk of burns to workers and improving product safety. In some embodiments, the sleeve 80 can completely cover the drying cylinder 10 or only partially cover its surface to ensure ease of installation.
[0080] In some preferred embodiments, a feeding hopper 801 is provided on the upper surface of the sleeve 80 near the first feed port 103, which is used to introduce the material from the feeder 60 into the drying cylinder 10. The feeding hopper 801 extends upward from the sleeve 80, and its cross-sectional area gradually increases as it moves away from the sleeve 80, so as to improve the material introduction effect.
[0081] In some preferred embodiments, the drying cylinder 10 has a first discharge port 108 at its bottom, located near the first feed port 103. The first discharge port 108 is equipped with an openable and closable door for opening or closing the discharge port. In some embodiments of this application, the drying cylinder is tilted, and the first feed port is located at a lower position. During application, the applicant has found that undried material may remain at the bottom of the drying cylinder, corresponding to the first feed port. The above technical solution allows the first discharge port 108 to be opened after drying to remove the remaining material, ensuring the cleanliness of the drying cylinder and thus guaranteeing the safety of the dried material. In this embodiment, the sleeve 80 does not cover the lower surface of the drying cylinder 10, or does not cover the portion of the lower surface of the drying cylinder 10 corresponding to the first discharge port 108, to facilitate the discharge operation.
[0082] In other embodiments of this application, a drying system is provided, comprising:
[0083] The first drying equipment is as described in the above embodiments;
[0084] The second drying equipment is as described in the above embodiments;
[0085] The second feed inlet 602 of the second drying equipment feeder 60 cooperates with the first discharge outlet 104 of the first drying equipment to receive the dried material released from the first discharge outlet 104, and transports it to the first feed inlet 103 of the second drying equipment through the second discharge outlet 603 of the feeder 60 for the second round of drying.
[0086] By adopting the above technical solution, a multi-round drying environment can be provided for the materials, thereby improving drying efficiency and ensuring the drying effect of crops.
[0087] Preferably, the first drying equipment and the second drying equipment are the same.
[0088] In summary, the electromagnetic heating drying equipment and drying system provided by this utility model embodiment can promptly discharge the hot air inside the drying drum by opening holes and adding an exhaust fan, preventing the hot air from condensing into condensate inside the drying drum. This achieves the technical effect of improving drying efficiency, solves the technical problems raised in the background art, improves the drying effect of the drying equipment in cold climates, and can significantly reduce the drying cost per unit of material, which is conducive to commercial promotion.
[0089] It should be noted that, for those skilled in the art, the technical features in the above embodiments can be freely combined, and the resulting technical solutions also belong to the embodiments disclosed in this application.
[0090] Furthermore, without departing from the principles of this application, several improvements and modifications may be made to this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
