Description

Technical Field

[0001] This utility model belongs to the field of high-temperature furnace technology, and specifically relates to a material delivery structure for use in high-temperature furnaces. Background Technology

[0002] In industrial processing fields such as crystal material production and metal heat treatment, muffle furnaces are commonly used high-temperature heating equipment and are widely used in material processing scenarios that require a high-temperature environment of around 800°C. Especially in the crystal growth and preparation process, a stable high-temperature environment is the key to ensuring the integrity of the crystal structure and the stability of its performance.

[0003] Currently, most muffle furnaces use side-opening or front-opening door designs. This leads to a significant problem of high-temperature overflow when the furnace door is opened during the unloading process after crystal production. Because the interior of a muffle furnace maintains a high temperature environment of around 800°C for extended periods, the large amount of high-temperature gas and radiant heat accumulated inside the furnace rapidly diffuses and corrodes the external environment the moment the door is opened. This not only causes thermal damage to the equipment components surrounding the main body of the muffle furnace and shortens the service life of related auxiliary equipment, but also causes a sharp rise in the temperature of the operating area, compromising the safety of the surrounding working environment.

[0004] This also poses serious safety hazards to the material handling process. The existing material handling method requires external tools such as long-handled pliers and iron hooks, which are manually inserted into the high-temperature furnace chamber by workers to remove the crystals. During this operation, workers need to be in close contact with the high-temperature gas overflowing from the furnace opening, and the positioning accuracy of the tools when inserted into the furnace is poor. This not only easily leads to burns due to high-temperature radiation or accidental contact with the furnace wall, but also may cause crystal collisions and breakage due to improper operation, affecting product quality.

[0005] Furthermore, the operation is inconvenient and inefficient. When manually retrieving materials using external tools, workers need to precisely control the depth and force of the tool insertion, making the operation process cumbersome and each material retrieval time-consuming. Especially in mass production scenarios, frequent material retrieval operations will significantly reduce overall production efficiency and increase the labor intensity of workers. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material delivery structure for use in high-temperature furnaces.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a feeding structure for use in a high-temperature furnace, comprising a muffle furnace body, the muffle furnace body comprising a furnace body component and a door component, the door component being located on one side of the muffle furnace body, a support plate being provided on the inner side of the furnace body component, and side strips being snapped onto both sides of the support plate, the inner wall of the furnace body component having symmetrically distributed side slots, the side slots being slidably engaged with the side strips, a fixing component being snapped onto the end of the side strip away from the door component, and limiting components being snapped onto both sides of the interior of the furnace body component, located on one side of the side slots, the limiting components being abutted against the fixing components;

[0008] The inner side of the tray is fitted with symmetrically arranged meshing racks, and the surfaces of the two meshing racks are meshed with meshing gears.

[0009] Preferably, a symmetrically distributed slider is snapped onto one side of the tray, and a sliding groove is provided on the inner side of the furnace body, with the slider and the sliding groove used in sliding cooperation.

[0010] Preferably, a rotating rod is fixedly inserted at the axis of both meshing gears, and the rotating rod is rotatably connected to the inner side of the furnace body through a bearing. The end of the rotating rod away from the support plate is coaxially fitted with a transmission gear, and the transmission gear is located inside the furnace body.

[0011] Preferably, a second transmission gear meshes with the surface of the first transmission gear, a second rotating rod is fixedly inserted into the shaft of the second transmission gear, and the second rotating rod is rotatably connected to the furnace body component through a bearing.

[0012] Preferably, the door component is fitted with symmetrically arranged connectors on the side near the furnace component, and both ends of the connectors are fitted with symmetrically distributed mounting components. The inner sides of the two mounting components are respectively rotatably connected to connecting plate one and connecting plate two.

[0013] Preferably, the ends of connecting plates one and two away from the door component extend into the inner side of the furnace body component, and connecting plates one and two are rotatably connected to a connecting plate three via a rotating shaft. Support rod one and support rod two are fixedly inserted into the ends of connecting plates one and two away from the door component, and there are two support rods one and two support rods two in total, which are symmetrically arranged on both sides of the inner side of the furnace body component.

[0014] Preferably, a support rod three is provided between support rod one and support rod two on one side of the rotating rod two, and a rotating gear is coaxially fixedly sleeved on the surfaces of support rod one, support rod two and support rod three on one side of the rotating rod two.

[0015] Preferably, one end of the second support rod and the first rotating rod located inside the rotating gear extends to the outside of the furnace body, and one end of the second support rod and the second rotating rod located outside the furnace body are coaxially fixedly fitted with a synchronous pulley, and the two synchronous pulleys are connected by a synchronous belt for transmission.

[0016] Preferably, one end of the rotating rod is provided with a drive motor that is connected to the furnace body component by a mounting bracket, and the output end of the drive motor is fixedly connected to the rotating rod through a coupling.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. When internal crystals form and material needs to be unloaded or retrieved, the drive motor can be operated to synchronously rotate the second rotating rod and the second support rod under the action of a series of transmission structures. During the rotation of the second support rod, the position parameters and attitude of the connecting parts are precisely controlled through the connecting plates one and two. The entire operating state of the door component driven by the connecting parts smoothly transitions from a lateral movement mode to a longitudinal movement mode, allowing the door component connected to it to expose one side of the furnace body for easy material retrieval. With the rotation of the second support rod, the tray containing the processed material will ultimately be pushed outwards towards the outside of the furnace body, facilitating material retrieval for the operator.

[0019] 2. During the lateral movement of the door component, the connection with the furnace body is switched from a sealed, fitted state to a gapped state. The high temperature inside the furnace body component will instantly rise from this gap. This opening method effectively reduces the risk of burns to personnel under existing door opening modes. By utilizing the natural rising characteristic of high-temperature gas with a density lower than air, direct contact with workers is reduced, thus effectively avoiding safety hazards. Finally, the door component moves longitudinally away from the support plate, changing the horizontal relative position between the door component and the furnace body component, thereby expanding the operable space inside the furnace body component and facilitating subsequent operations.

[0020] 3. During equipment operation, the pallet and door components move synchronously through a high-temperature resistant transmission structure. During the material unloading phase of the muffle furnace, the drive motor rotates the second rotating rod clockwise, which opens the door component. During this process, the meshing of transmission gear one and transmission gear two, utilizing the design characteristics of large and small gears, amplifies the rotation of the second rotating rod to the first rotating rod, providing the necessary power for the stable extension of the pallet. When the drive motor rotates the second rotating rod counterclockwise, the pallet gradually retracts into the furnace body, and the door component simultaneously resets to its initial sealing position, providing a reliable sealing environment for the storage or subsequent processing of materials inside the muffle furnace.

[0021] 4. During the movement of the pallet, the movement is guided primarily by the slider and the groove, and the engagement relationship between the side strip and the side slot further provides stability and guidance for the movement of the pallet. Finally, at the end of the pallet's movement to the feasible position, its limiting and fixing parts abut against each other, providing limiting and stability for the movement and anti-detachment of the pallet.

[0038] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0039] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0040] Example:

[0041] refer to Figures 1-6 A feeding structure for use in a high-temperature furnace includes a muffle furnace body 1. The muffle furnace body 1 includes a furnace body component 101 and a door component 102, with the door component 102 located on one side of the muffle furnace body 1. A support plate 2 is provided on the inner side of the furnace body component 101, and side strips 201 are snapped onto both sides of the support plate 2. The inner wall of the furnace body component 101 has symmetrically distributed side slots 202, and the side slots 202 and the side strips 201 are slidably engaged. A fixing member 203 is snapped onto the end of the side strip 201 away from the door component 102. Limiting members 204 located on one side of the side slots 202 are snapped onto both sides inside the furnace body component 101, and the limiting members 204 and the fixing members 203 are abutted together.

[0042] The inner side of the tray 2 is fitted with symmetrically arranged meshing racks 3, and the surfaces of the two meshing racks 3 are meshed with meshing gears 301.

[0043] Specifically, during the movement of the pallet 2, the movement is guided primarily by the slider 205 and the groove 206, and the engagement relationship between the side strip 201 and the side slot 202 further provides stability and guidance for the movement of the pallet 2. Finally, at the end of the pallet 2 when it moves to the feasible position, its limiting member 204 and fixing member 203 abut against each other, providing limiting and stability for the movement and anti-detachment of the pallet 2.

[0044] The pallet 2 has a symmetrically distributed slider 205 snapped onto one side, and the furnace body 101 has a groove 206 on the inner side, and the slider 205 and the groove 206 are used in sliding cooperation.

[0045] Specifically, the sliding connection between slider 205 and slide groove 206 enables the pallet 2 to move and guide within the furnace body 101, providing reliable support for the smooth movement of pallet 2 and ensuring that pallet 2 always operates stably within the preset trajectory and range. In response to the actual working requirements of the muffle furnace body 1, high-temperature alloys will be selected as the base material for slider 205 and slide groove 206 as needed, and a special solid lubricating coating will be used to ensure smooth sliding performance between slider 205 and slide groove 206.

[0046] A rotating rod 302 is fixedly inserted at the axis of both meshing gears 301, and the rotating rod 302 is rotatably connected to the inner side of the furnace body 101 through a bearing. A transmission gear 4 is coaxially engaged at the end of the rotating rod 302 away from the support plate 2, and the transmission gear 4 is located inside the furnace body 101. A transmission gear 401 meshes with the surface of the transmission gear 401, and a rotating rod 402 is fixedly inserted at the axis of the transmission gear 401, and the rotating rod 402 is rotatably connected to the furnace body 101 through a bearing.

[0047] Specifically, when the rotating rod 402 rotates, it will drive the transmission gear 401 to rotate synchronously through the fixed assembly; with the help of the meshing transmission mechanism between the gears, the synchronous linkage rotation of the transmission gear 4 and the rotating rod 302 can be realized, thereby enabling the two meshing gears 301 to form a stable state of coordinated meshing rotation.

[0048] A symmetrically arranged connector 5 is snapped onto the side of the door component 102 near the furnace component 101, and both ends of the connector 5 are snapped onto symmetrically distributed mounting components 501. The inner sides of the two mounting components 501 are respectively rotatably connected to connecting plate 1 6 and connecting plate 2 601. The ends of connecting plate 1 6 and connecting plate 2 601 away from the door component 102 extend into the inner side of the furnace component 101, and connecting plate 1 6 and connecting plate 2 601 are rotatably connected to connecting plate 3 602 through a rotating shaft. The ends of connecting plate 1 6 and connecting plate 2 601 away from the door component 102 are respectively fixedly inserted with support rod 1 7 and support rod 2 701, and there are two of each of support rod 1 7 and support rod 2 701, which are symmetrically arranged on both sides of the inner side of the furnace component 101.

[0049] Specifically, when support rod 1 7 and support rod 2 701 rotate, they will drive connecting plate 1 6 and connecting plate 2 601 to rotate around the axis of support rod 1 7 and support rod 2 701 respectively. Furthermore, the rotation angle adjustment and attitude adjustment of connecting plate 1 6 and connecting plate 2 601 are further synchronized by the presence of connecting plate 3 602. Thus, through the coordinated rotation of connecting plate 1 6 and connecting plate 2 601, the position parameters and attitude state of connecting part 5 can be precisely controlled.

[0050] During the adjustment process of connecting plate 1 6 and connecting plate 2 601 from the initial state to the final stroke limit position, the operating state of connecting piece 5 will smoothly transition from the horizontal movement mode to the vertical movement mode, so that the door piece 102 connected to it can expose one side of the furnace piece 101 for easy material handling.

[0051] A support rod 702, rotatably connected to the furnace body 101, is provided between support rod 7 and support rod 701 on one side of the rotating rod 402. A rotating gear 703 is coaxially fixedly sleeved on the surfaces of support rod 7, support rod 701 and support rod 702 on one side of the rotating rod 402. One end of support rod 701 and rotating rod 302 located inside the rotating gear 703 extends to the outside of the furnace body 101. A synchronous pulley 8 is coaxially fixedly sleeved on one end of support rod 701 and rotating rod 402 located outside the furnace body 101. A synchronous belt 801 is connected between the two synchronous pulleys 8 for transmission. A drive motor 9 is provided at one end of rotating rod 402 and is installed in connection with the furnace body 101 by a mounting bracket. The output end of the drive motor 9 is fixedly sleeved between rotating rod 402 and rotating rod 402 by a coupling.

[0052] Specifically, when the drive motor 9 is running, it will drive the rotating rod 402 and the transmission gear 401 on its surface to rotate synchronously. At the same time, the rotational power is effectively transmitted to the support rod 701 through the transmission mechanism of the synchronous pulley 8 and the synchronous belt 801.

[0053] Support rod 2 701 drives the rotating gear 703 on its surface to rotate synchronously. Through the meshing transmission between the gears, the three rotating gears 703 achieve coordinated meshing transmission. Simultaneously, based on the directional characteristics of the meshing transmission, support rod 1 7 rotates in the same direction as support rod 2 701, while support rod 3 702 rotates in the opposite direction to support rod 1 7 and support rod 2 701, thus achieving synchronous linkage between support rod 1 7 and support rod 2 701 and providing a stable transmission path for their power transmission. Each gear is made of nickel-based high-temperature alloy, and the bearings are silicon nitride ceramic bearings, specifically adapted to the high-temperature working environment of the muffle furnace body 1, ensuring reliable operation of the components under extreme temperature conditions.

[0054] The working principle of this utility model:

[0055] In the use of this high-temperature furnace, when the internal crystals are formed and it is necessary to feed or unload them, the drive motor 9 can be run to drive the rotating rod 402 and the transmission gear 401 on its surface to rotate synchronously. At the same time, the synchronous rotation of the rotating rod 402 and the support rod 701 can be achieved by means of the transmission mechanism of the synchronous pulley 8 and the synchronous belt 801.

[0056] During the rotation of support rod 2 701, the rotating gear 703 on its surface will rotate synchronously. Through the meshing transmission between the gears, the three rotating gears 703 will achieve coordinated meshing transmission. At the same time, based on the directional characteristics of the meshing transmission, support rod 1 7 and support rod 2 701 will rotate in the same direction. When support rod 1 7 and support rod 2 701 rotate, they will drive connecting plate 1 6 and connecting plate 2 601 to form a rotational tendency. Furthermore, the rotation angle adjustment and attitude adjustment of connecting plate 1 6 and connecting plate 2 601 are further synchronized and linked by the presence of connecting plate 3 602, thereby enabling precise control of the position parameters and attitude state of the connecting piece 5.

[0057] During the adjustment process of connecting plate 1 6 and connecting plate 2 601 from the initial state to the final stroke limit position, the operating state of connecting piece 5 will smoothly transition from the horizontal movement mode to the vertical movement mode, so that the door piece 102 connected to it can expose one side of the furnace piece 101 for easy material handling.

[0058] During the rotation of support rod 2 701, rotating rod 2 402 synchronously drives transmission gear 2 401 to rotate. At this time, with the help of the meshing transmission mechanism between gears, the synchronous linkage rotation of transmission gear 1 4 and rotating rod 1 302 can be achieved, thereby enabling the two meshing gears 301 to form a stable state of coordinated meshing rotation. Rotating rod 1 302 will drive the two meshing gears 301 to rotate, thereby realizing the movement of meshing rack 3 and pallet 2. At this time, the movement of pallet 2 will be guided primarily by slider 205 and slide groove 206, and the engagement relationship between side strip 201 and side slot 202 further provides stability and guidance for the movement of pallet 2. Finally, at the end of the pallet 2 when it moves to the workable position, its limiting member 204 and fixing member 203 abut against each other, providing limiting and stability for the movement and anti-disengagement of pallet 2.

[0059] During equipment operation, the pallet 2 and the door component 102 achieve coordinated and synchronous operation through a high-temperature resistant transmission structure. During the material unloading stage of the muffle furnace body 1, the drive motor 9 drives the rotating rod 402 to rotate clockwise, which drives the door component 102 to open; when the drive motor 9 drives the rotating rod 402 to rotate counterclockwise, the pallet 2 will gradually retract to the inside of the furnace body 101, and at the same time, the door component 102 will synchronously reset to the initial sealing position, providing a reliable sealing environment for the storage or subsequent processing of materials inside the muffle furnace body 1.
