Description

Technical Field

[0001] This utility model relates to the field of graphene heating and insulation technology, and in particular to a built-in multilayer graphene heating and insulation device. Background Technology

[0002] Graphene heating and insulation technology utilizes the excellent thermal conductivity and electrothermal conversion efficiency of graphene materials to convert electrical energy into heat energy to achieve heating and insulation functions. It is widely used in industrial material heating, food processing, equipment insulation and other fields. It can quickly raise the temperature of the target object and maintain a stable temperature environment, reduce energy loss and meet the industrial demand for energy conservation and consumption reduction.

[0003] In actual industrial production, the application of this type of technology has some shortcomings: On the one hand, traditional heating and insulation devices are mostly single-layer heating structures, with limited heating range and uneven temperature distribution, making it difficult to heat large quantities of materials efficiently and uniformly; On the other hand, the material conveying and heating / insulation processes are not well connected, often resulting in material accumulation and blockage of the feed inlet. Material can easily enter subsequent processes in large quantities at once, leading to insufficient heating. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a built-in multi-layer graphene heating and insulation device, which overcomes the shortcomings of the existing technology and effectively solves the problems of uneven temperature caused by single-layer heating in traditional devices and poor connection between material conveying and heating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An embedded multi-layer graphene heating and insulation device includes a base. A conveyor is fixedly connected to the top outer wall of the base by screws, and a servo motor is fixedly connected to one side outer wall of the conveyor by screws. The output shaft of the servo motor is fixedly connected to a rotating column through a coupling. A baffle plate is welded to the bottom outer wall of the rotating column. A rotating disk is welded to one end outer wall of the rotating column, and a connecting rod is hinged to one side outer wall of the rotating disk. A pull rod is hinged to one end outer wall of the connecting rod, and a scraper is welded to one end outer wall of the pull rod. An insulation box is installed on the top outer wall of the base. An array of drive motors is fixedly connected to the top outer wall of the insulation box by screws, and a fan is fixedly connected to the output shaft of the drive motor. An array of mounting frames is set inside the insulation box, and graphene heating elements are installed on the inner wall of the mounting frames. An electric butterfly valve is set on the top outer wall of the insulation box.

[0006] Preferably, an insulated box is installed on the top outer wall of the base, and an adjacent set of observation windows is provided on one side of the outer wall of the insulated box.

[0007] Preferably, the fan is located inside the insulation box, and the graphene heating element is located below the fan, and the electric butterfly valve is connected to the insulation box.

[0008] Preferably, a feed hopper is fixedly connected to the top of the outer wall of one end of the conveyor by screws, and a scraper is located between the feed hopper and the insulation box.

[0009] Preferably, the base has an array of support frames welded to its bottom outer wall, and the support frames are equipped with casters on their bottom outer walls.

[0010] Preferably, a speed reducer is fixedly connected to the inner wall of one of the support frames by screws, and a rotating shaft is provided at both ends of the conveyor, with a pulley pair installed between the rotating shaft and the speed reducer.

[0011] Preferably, one side of the top outer wall of the conveyor is provided with adjacent guide plates, and the tie rod is provided through the inner wall of the guide plate. The other side of the top outer wall of the conveyor is provided with a positioning column, and one end of the scraper is slidably connected to the outer wall of the positioning column.

[0012] The beneficial effects of this utility model are as follows: 1. The built-in multi-layer graphene heating and insulation device in this design forms a multi-layer heating structure by setting graphene heating elements inside the insulation box. With the help of a drive motor to drive the fan, the heat generated by the graphene heating elements is evenly distributed to all areas of the insulation box. This solves the problem of uneven temperature distribution in traditional single-layer heating devices, greatly improving the uniformity and efficiency of material heating. At the same time, the electric butterfly valve can flexibly adjust the air pressure and heat dissipation rate inside the insulation box, further ensuring the stability of the temperature inside the insulation box and avoiding the defects of traditional devices that are difficult to control the temperature. 2. The built-in multi-layer graphene heating and insulation device in this design uses a servo motor to drive the rotating column, connecting rod, and tie rod to move the scraper. The baffle plate at the bottom of the rotating column rotates synchronously with the rotating column, which can block and divert the material on the conveyor. The scraper can also effectively flatten the material between the feed hopper and the insulation box, avoiding material accumulation and blockage, and preventing a large amount of material from entering the subsequent stages at once, which would lead to insufficient heating.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 Example 1: An internal multilayer graphene heating and insulation device includes a base 1. A conveyor 2 is fixedly connected to the top outer wall of the base 1 by screws, and a servo motor 3 is fixedly connected to one side outer wall of the conveyor 2 by screws. The output shaft of the servo motor 3 is fixedly connected to a rotating column 4 by a coupling. A baffle plate 5 is welded to the bottom outer wall of the rotating column 4. A rotating disk 6 is welded to one end outer wall of the rotating column 4, and a connecting rod 7 is hinged to one side outer wall of the rotating disk 6. A pull rod 8 is hinged to one end outer wall of the connecting rod 7, and a scraper 9 is welded to one end outer wall of the pull rod 8.

[0017] In this embodiment, the servo motor 3 drives the rotating column 4 to rotate, and the baffle plate 5 at the bottom of the rotating column 4 rotates synchronously with the rotating column 4. This can block and divert the material on the conveyor 2, preventing a large amount of material from entering the subsequent stages at once. The rotating disk 6 rotates with the rotating column 4, and the connecting rod 7 drives the pull rod 8 to reciprocate. The scraper 9 at one end of the pull rod 8 slides along the outer wall of the positioning column 23 under the drive of the pull rod 8. At the same time, the guide plate 22 limits the movement direction of the pull rod 8 to prevent the pull rod 8 from deviating and causing the scraper 9 to be unable to work accurately. This ensures that the scraper 9 reciprocates stably between the feed hopper 16 and the insulation box 10, effectively preventing the material from accumulating at the outlet of the feed hopper 16, ensuring that the material is uniformly and stably delivered into the insulation box 10, providing a stable material supply for the subsequent heating and insulation stages, and avoiding the impact of uneven material supply on heating efficiency.

[0018] In embodiment 2, an insulation box 10 is installed on the top outer wall of the base 1. An array of drive motors 11 are fixedly connected to the top outer wall of the insulation box 10 by screws, and a fan 12 is fixedly connected to the output shaft of the drive motors 11. An array of mounting brackets 13 are provided inside the insulation box 10, and adjacent graphene heating elements 14 are installed on the inner wall of the mounting brackets 13. Adjacent electric butterfly valves 15 are provided on the top outer wall of the insulation box 10.

[0019] In this embodiment, the insulation box 10 installed on the top of the base 1 provides a closed space for heating and insulating materials, reducing heat loss and ensuring insulation effect. After the drive motor 11 on the top of the insulation box 10 is started, the output shaft of the drive motor 11 drives the fan 12 to rotate inside the insulation box 10. The graphene heating element 14 below the fan 12 generates heat after being energized. The fan 12 delivers the heat downwards and diffuses it inside the insulation box 10. When the temperature inside the box is too high, the electric butterfly valve 15 opens to dissipate heat, and when the temperature is too low, it closes to retain heat, realizing flexible control of the temperature inside the box and meeting the heating and insulation needs of different materials.

[0020] The base 1 has an insulation box 10 installed on its top outer wall, and an observation window 21 is provided on one side of the outer wall of the insulation box 10. The fan 12 is located inside the insulation box 10, and the graphene heating element 14 is located below the fan 12. The electric butterfly valve 15 is connected to the insulation box 10.

[0021] With the above solution, staff can observe the heating status of the materials inside the insulation box 10 in real time through the observation window 21, which makes it easier to detect and deal with abnormalities such as material blockage and heating element failure in a timely manner, and ensure the stable operation of the heating and insulation process.

[0022] The top of the outer wall of one end of the conveyor 2 is fixedly connected to the feed hopper 16 by screws, and the scraper 9 is located between the feed hopper 16 and the heat preservation box 10.

[0023] Through the above scheme, the feed hopper 16 provides a centralized feeding channel for materials. The scraper 9 is located between the feed hopper 16 and the insulation box 10. During the reciprocating motion, it can quickly flatten the materials that fall from the outlet of the feed hopper 16 onto the conveyor 2, ensuring that the material conveying channel is unobstructed.

[0024] The base 1 has an array of support frames 17 welded to its bottom outer wall, and the support frames 17 are equipped with casters 18. A reducer 19 is fixedly connected to the inner wall of one of the support frames 17 by screws. The conveyor 2 has a rotating shaft at both ends, and a pulley pair 20 is installed between the rotating shaft and the reducer 19.

[0025] Through the above scheme, the support frame 17 at the bottom of the base 1 provides stable support for the entire device. The universal wheels 18 at the bottom of the support frame 17 have a braking function. When pushing the device, the universal wheels 18 can turn flexibly, which makes it convenient for the staff to adjust the position of the device according to the layout of the production site. By adjusting the output speed of the reducer 19, the rotation speed of the conveyor 2 shaft can be controlled, thereby adjusting the conveying speed of the conveyor 2, so that the speed of the conveyor 2 conveying materials is matched with the heating efficiency of the insulation box 10, thereby improving product quality and production efficiency.

[0026] One side of the top outer wall of the conveyor 2 is provided with adjacent guide plates 22, and the pull rod 8 is provided through the inner wall of the guide plate 22. The other side of the top outer wall of the conveyor 2 is provided with a positioning post 23, and one end of the scraper 9 is slidably connected to the outer wall of the positioning post 23.

[0027] Through the above scheme, the guide plate 22 on one side of the top of the conveyor 2 provides motion guidance for the pull rod 8, ensuring the stability of the scraper 9's movement trajectory and ensuring the scraping effect. The positioning column 23 is slidably connected to one end of the scraper 9, further limiting the scraper 9 so that the scraper 9 always remains parallel to the conveyor 2 table surface, preventing the scraper 9 from shaking.

[0028] Working principle: Before operation, the operator moves the device to the designated production position by pushing it with the casters 18 at the bottom of the base 1. Then, the operator brakes the casters 18 to fix the device in position and prevent slippage during operation. Next, the reducer 19 on the support frame 17 is started. The reducer 19 drives the rotating shafts at both ends of the conveyor 2 to rotate through the pulley pair 20. The conveyor 2 then starts to operate stably at the preset speed, preparing for material conveying. The material to be heated is poured into the feed hopper 16 at the top of one end of the conveyor 2. The feed hopper 16 guides the material to fall evenly onto the platform of the conveyor 2, preventing spillage or accumulation. At the same time, the servo motor 3 on one side of the conveyor 2 is started. The output shaft of the servo motor 3 drives the rotating column 4 to rotate through the coupling. The rotating disk 6 at one end of the rotating column 4 rotates synchronously. Through the hinged connecting rod 7, the pull rod 8 is driven to reciprocate along the guide plate 22. The scraper 9 at one end of the pull rod 8 slides along the outer wall of the positioning column 23 under the action of the pull rod 8, continuously and evenly scraping the material between the feed hopper 16 and the heat preservation box 10 toward the inlet of the heat preservation box 10, ensuring that the material enters the heat preservation box 10 smoothly. After the material enters the insulation box 10, the drive motor 11 on the top of the insulation box 10 and the graphene heating element 14 on the internal mounting bracket 13 are activated. The drive motor 11 drives the fan 12 to rotate inside the insulation box 10, quickly dispersing the heat generated by the graphene heating element 14 to all corners of the insulation box 10. The multi-layered distribution of the graphene heating element 14 ensures uniform temperature inside the box, meeting the heating requirements of the material. Personnel can monitor the heating status of the material inside the insulation box 10 in real time through the observation window 21 on one side. If the temperature inside the insulation box 10 is too high, the electric butterfly valve 15 is opened to dissipate heat; if the temperature is too low, the electric butterfly valve 15 is closed to retain heat and maintain a stable temperature environment inside the box. After the material has been heated and kept warm in the insulation box 10, it is output from the other end of the insulation box 10 as the conveyor 2 is running. The baffle plate 5 at the bottom of the rotating column 4 rotates to divert the material on the conveyor 2, preventing the material from accumulating and facilitating its entry into the subsequent production process.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
