Abstract
Description
Technical Field
[0001] This utility model relates to the field of new material processing equipment technology, specifically a heating device for new material processing. Background Technology
[0002] New materials refer to materials with special properties or functions that have been developed or improved in recent years. They typically offer significant improvements over traditional materials in terms of strength, temperature resistance, conductivity, and lightweighting. New materials include high-performance structural materials, functional materials, and nanomaterials. During the preparation and processing of new materials, relevant heat treatments are required to determine the material's decomposition temperature, glass transition temperature (e.g., polymer materials), or phase transition point (e.g., metals / ceramics). This prevents overheating that could lead to decomposition or performance degradation. Furthermore, because some materials (e.g., titanium alloys, graphene) are easily oxidized at high temperatures, heating in an inert gas (nitrogen, argon) or vacuum environment is necessary.
[0003] There are various types of heating devices for new materials, including traditional box-type resistance furnaces (suitable for ceramics, metal alloys, and polymer sintering), tube furnaces (suitable for nanomaterials (such as carbon nanotubes) and thin film materials); or induction heating furnaces for rapid heating (suitable for conductive materials (such as metallic glass and high-entropy alloys)), microwave sintering furnaces (suitable for ceramics (such as Al2O3) and nanocomposite materials), and laser heating systems (suitable for precision machining (such as graphene patterning and metal 3D printing)). All different types of heating devices need to maintain good internal sealing during operation to ensure a constant internal temperature and enable them to heat new materials efficiently.
[0004] Among them, traditional tube furnaces are commonly used heating equipment in new material research and production. They have good temperature control, are suitable for heating and treating materials of various forms, and have advantages over large box furnaces, such as small heating volume, high energy efficiency, and low replacement cost of heating elements and reaction tubes.
[0005] However, most existing tube furnaces lack flexibility in use, meaning the entire heating tube is in a fixed operating state. When heating new materials inside, there is insufficient heating uniformity, which affects the heating speed. Although the existing method is to set up a corresponding stirring mechanism inside the tube to mix the new materials, there are still cases of inadequate stirring or insufficient contact.
[0006] To address this issue, this technical solution proposes a novel heating device for material processing. Utility Model Content
[0007] The purpose of this invention is to provide a new heating device for material processing to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A heating device for processing new materials includes a horizontal heating tank. A door is hinged to the outer circumferential wall of the horizontal heating tank for the entry and exit of new materials and related heating materials. A set of main support shafts is arranged along the axis of the horizontal heating tank, with both ends extending outside the tank. The horizontal heating tank rotates around the main support shafts to dynamically heat the new materials placed inside. A set of track cylinders is fixedly installed on one side of the main support shafts inside the horizontal heating tank. The axis of the track cylinders coincides with the axis of the horizontal heating tank, and their outer circumferential wall slides in contact with the inner wall of the horizontal heating tank. Meanwhile, a ring of rails is opened on the outer wall of the track cylinder. The upper and lower sides of the rails are axially staggered and connected by symmetrical sliding rails on both sides. A slider is installed on the inner wall of the horizontal heating tank corresponding to the rail. The slider slides along the inside of the rail. At the same time, a set of rotating mechanisms is telescopically connected to one side of the horizontal heating tank. The rotating mechanism is used to drive the horizontal heating tank to rotate. Under the cyclic drive of the rotation axis of the slider and the rail, the horizontal heating tank is controlled to rotate and move laterally. This drives the new material inside the horizontal heating tank to fully move and contact the hot air for heating.
[0010] Compared with the prior art, the beneficial effects of this utility model are: by using compound motion to make the material roll in multiple directions, local overheating is avoided and heating efficiency is improved. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] Please see Figures 1-5A heating device for processing new materials includes a horizontal heating tank 10. A tank door 11 is hinged to the outer circumferential wall of the horizontal heating tank 10 for the entry and exit of new materials and related heating materials. A set of main support shafts 15 is arranged along the axis of the horizontal heating tank 10, with both ends extending to the outside of the horizontal heating tank 10. The horizontal heating tank 10 rotates around the main support shafts 15 to dynamically heat the new materials placed inside. A set of track cylinders 22 is fixedly installed on one side of the main support shafts 15 inside the horizontal heating tank 10. The axis of the track cylinders 22 coincides with the axis of the horizontal heating tank 10, and their outer circumferential walls slide against the inner wall of the horizontal heating tank 10. Simultaneously, a ring of rails 23 is formed on the outer wall of the track cylinder 22. The rails 23 are axially staggered on the upper and lower sides and symmetrically connected by slide rails on both sides. A slider 24 is installed on the inner wall of the horizontal heating tank 10 corresponding to the rails 23. The slider 24 slides along the inside of the rails 23. At the same time, a set of rotating mechanisms is telescopically connected to one side of the horizontal heating tank 10. The rotating mechanisms are used to drive the horizontal heating tank 10 to rotate. Under the cyclic drive of the rotation axis of the slider 24 and the rails 23, the horizontal heating tank 10 is controlled to rotate and move laterally, thereby driving the new material inside the horizontal heating tank 10 to fully move and contact the hot air for heating.
[0022] In this embodiment of the invention, the two ends of the main support shaft 15 are supported and positioned by the support rod frame 20. The support rod frame 20 is set as a quasi-isosceles trapezoidal structure to increase its stability when placed.
[0023] The rotating mechanism includes a driven tooth 19 mounted on the main support shaft 15. A driving tooth 18 meshes with one side of the driven tooth 19. A servo motor 16 is connected to the middle of one side of the driving tooth 18 via an output shaft 17. The bottom of the servo motor 16 is also supported by a support rod frame 20. Multiple positioning telescopic rods 21 are installed at equal intervals in a ring on the side of the driven tooth 19 facing the end wall of the horizontal heating tank 10. The ends of the positioning telescopic rods 21 extend through the end wall of the horizontal heating tank 10 and into the horizontal heating tank 10. That is, when the driven tooth 19 rotates, the horizontal heating tank 10 is rotated synchronously by the limiting between the multiple sets of positioning telescopic rods 21 and the horizontal heating tank 10.
[0024] Specifically, the telescopic range of the positioning telescopic rod 21 inserted into the horizontal heating tank 10 is greater than the axial travel of the slider 24 sliding inside the track 23, ensuring that the horizontal heating tank 10 can be stably controlled to rotate when the driven tooth 19 rotates.
[0025] Sealing rings are provided at the connection points between the main support shaft 15 and the horizontal heating tank 10, and between the positioning telescopic rod 21 and the horizontal heating tank 10 for telescopic rotation, to prevent heat from leaking out of the horizontal heating tank 10.
[0026] In one embodiment of the present invention, to prevent new material placed inside the horizontal heating tank 10 from being squeezed into the space between the outer circumferential wall of the track cylinder 22 and the interior of the horizontal heating tank 10, or flowing into the track 23, when the horizontal heating tank 10 is moving, thus affecting the normal rotation of the slider 24, an arc-shaped inclined retaining ring (not shown in the figure) is installed at the edge of both ends of the track cylinder 22. The retaining ring slides in contact with the inner wall of the horizontal heating tank 10, while preventing the new material from flowing out into the area between the track cylinder 22 and the inner wall of the horizontal heating tank 10.
[0027] It should be noted that the principle of heating new materials inside the horizontal heating tank 10 is mainly based on electrothermal conversion, heat conduction / radiation heat transfer, and atmosphere control.
[0028] The specific heating principle is as follows: A heating wall 25 is provided on the inner wall of the horizontal heating tank 10. Heating elements (resistance wire / silicon carbide rod / molybdenum wire) are uniformly distributed in the tank wall of the horizontal heating tank 10 corresponding to the heating wall 25. After the heating elements are energized, electrical energy is converted into heat energy and then transferred to the heating wall 25. After passing through the heating wall 25, the heat energy is released towards the inside of the horizontal heating tank 10, thereby heating the new material. A wireless energy transmission system is provided on the outer wall of the horizontal heating tank 10. The wireless energy transmission system is connected to the heating elements and supplies them with power. That is, it is connected to an external power source through the wireless energy transmission system, so that it can still supply power when the horizontal heating tank 10 is in a rotating state.
[0029] The heating wall 25 is usually made of quartz, corundum or silicon carbide to ensure good thermal conductivity and a certain degree of corrosion resistance.
[0030] The operation of the wireless energy transmission system is a conventional technology, and its specific operating principle is as follows: It includes a coil 12, which includes a primary coil: fixed on the outer side of the horizontal heating tank 10 and connected to an external power source;
[0031] Secondary coil: Installed on the inner side of the outer wall of the horizontal heating tank 10, it obtains electrical energy through electromagnetic induction (non-contact type).
[0032] Rectifier circuit: Converts induced alternating current into direct current for use by the heating element.
[0033] The above is only a brief description of the wireless power transmission system. For detailed operating principles and processes, please refer to existing technologies. They will not be elaborated upon or limited here.
[0034] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control.
[0035] Loading: Open tank door 11 to put in the material, close it and fill with inert gas.
[0036] Heating activated: Heating wall 25 is powered on and generates heat, while the wireless power supply system maintains continuous power supply during rotation.
[0037] Dynamic heating: Servo motor 16 drives the active gear 18 to rotate the driven gear 19;
[0038] Driven gear 19 pushes horizontal heating tank 10 to rotate via positioning telescopic rod 21;
[0039] Slider 24 slides along the misaligned track 23, driving the horizontal heating tank 10 to move horizontally and reciprocally in sync.
[0040] The material tumbles fully under the combined rotational and lateral motion, making uniform contact with the hot air.
[0041] End: After heating is complete, stop the movement, open the can door 11 and take out the material.
[0042] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.
[0043] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
