Description

Technical Field

[0001] The utility model belongs to the field of aluminum silicon carbide carbon brick baking devices, and in particular relates to a uniformly heated aluminum silicon carbide carbon brick baking device. Background Art

[0002] Aluminum silicon carbide carbon brick is a high-temperature ceramic material prepared by mixing, pressing and high-temperature sintering aluminum silicon carbide and silicon carbide powders. It has good thermal conductivity, electrical insulation, chemical stability and high-temperature stability. It is widely used in semiconductor manufacturing, laser devices, high-power electronic devices, microwave devices, thermal management systems and other fields. During the sintering process, a ring-shaped electric heating tube is often used to heat the aluminum silicon carbide carbon brick in the center of the ring to ensure uniform heating during sintering.

[0003] The existing aluminum silicon carbide carbon brick baking device often sets the cavity of the sintering furnace into a cylindrical shape that is compatible with the annular electric heating tube, and fixes the annular electric heating tube on the curved wall of the cylinder to set the heating source. Since sufficient operating space needs to be left in the furnace for workers to stack and fix, the internal space of the sintering furnace is relatively large, resulting in the electric heating tube on the inner wall of the sintering furnace being far away from the aluminum silicon carbide carbon brick, and the heat utilization efficiency during sintering is not high.

[0004] Therefore, in view of the problem that the above-mentioned aluminum silicon carbide carbon brick baking device fixes the annular heating tube on the cylindrical inner wall curved surface, and the heat pipe is far away from the brick body due to the need to reserve sufficient space for loading and unloading bricks, resulting in poor heat utilization efficiency, a uniformly heated aluminum silicon carbide carbon brick baking device is developed. By reducing the inner space of the aluminum silicon carbide carbon brick baking device, the heating tube is closer to the brick body, and a movable slide rail is added to the brick fixing structure, which facilitates the loading and unloading of the brick body while improving the heat utilization efficiency. Utility Model Content

[0005] In order to overcome the problem that the aluminum silicon carbide carbon brick baking device adopts the method of fixing the annular heating pipe on the cylindrical inner wall curved surface, the heat pipe is far away from the brick body due to the reserved space for loading and unloading the brick body, resulting in poor heat utilization efficiency.

[0006] The technical solution of the utility model is: a uniformly heated aluminum silicon carbide carbon brick baking device, including a furnace body, a pull-out base assembly, a movable support structure, an angle locking assembly, a brick body fixing structure, a flip assembly, and a heating structure. A pull-out base assembly that moves through a slide groove and a slider is arranged inside the furnace body, a movable support structure is arranged on the upper surface of the pull-out base assembly, an angle locking assembly is arranged on the side of the movable support structure, a brick body fixing structure is arranged at one end of the movable support structure, a flip assembly is arranged at the other end of the movable support structure, and a heating structure composed of a plurality of heating elements is arranged on the top surface of the furnace body.

[0007] Preferably, by pulling out the base assembly through the form of a slide groove and a slider, it is convenient for the user to drag the base to load and unload the brick body, thus saving the space inside the baking device for loading and unloading the brick body, shortening the distance between the heating device and the brick body, and improving the baking efficiency. The movable supporting structure locks the position of the connecting rod through the limiting structure to prevent the brick body from shifting and causing the flipping assembly to fail. The angle locking assembly locks the angle of the connecting rod through a pin connection to fix the position of the fixed frame, reducing the difficulty of loading and unloading the brick body. The brick body fixing structure fixes the brick body by screwing the frame cover with bolts to prevent the brick body from falling off during rotation baking. The flipping assembly flips the brick body through the transmission element of the high-temperature motor, making the baking more uniform. The heating structure is more cost-effective by splitting the size of the resistance heating device, saving economic costs and facilitating replacement.

[0008] Preferably, the pull-out base assembly includes a guide groove, a pull-out base, a guide block, and a handle. The furnace bottom plate is provided with a guide groove, a pull-out base is arranged above the furnace bottom plate, a guide block matched with the guide groove is arranged on the lower surface of the pull-out base, the guide block is slidably connected to the inner side of the guide groove, a handle is installed on the upper surface of the pull-out base, and small holes of the same size are provided on the pull-out base and the furnace bottom plate. The lower end of the handle is plugged and connected to the inner side of the small holes on the upper surface of the pull-out base and the bottom plate of the furnace body. The guide block slides in the guide groove, and the pull-out base is driven to move together, which is convenient for the user to drag the base to load and unload the brick body. There is no need to reserve loading and unloading space inside the baking device, so that the distance between the resistance heating device and the brick body is shortened, thereby improving the heating efficiency.

[0009] Preferably, the movable supporting structure includes a supporting column, a limiting ring, a connecting shaft and a limiting plate. Two supporting columns are fixedly connected to the upper surface of the pull-out base. The upper ends of the supporting columns are fixedly connected to the limiting rings. The connecting shaft is rotatably connected to the inner side of the hole in the center of the limiting ring. Two semicircular limiting plates are fixedly connected to the side of the connecting shaft. The horizontal position of the connecting shaft is limited by the limiting ring to prevent the connecting shaft from shifting and falling off when the transmission shaft rotates, causing failure of the flip assembly.

[0010] Preferably, the angle locking assembly includes a fixing plate, a fixing pin and a fixing bolt. A fixing plate is fixedly connected to the side of the limit plate close to the handle. A matching fixing pin is plugged in and connected to the hole opened on the side of the limit ring. Circular holes corresponding to the positions are opened on the surfaces of the fixing plate and the fixing pin. The fixing bolt is plugged in and connected to the circular holes of the fixing plate and the fixing pin. The angle of the connecting shaft is locked by the fixing bolt passing through the holes of the fixing plate and the fixing pin from top to bottom, so as to prevent the connecting shaft from deflecting when loading and unloading the brick body, thereby reducing the difficulty of loading and unloading.

[0011] Preferably, the brick body fixing structure includes a fixing frame and a fixing cover. The end of the connecting shaft is fixedly connected to the fixing frame. The upper surface of the fixing frame is screwed with a fixing cover by bolts. The fixing frame and the fixing cover are both hollow structures composed of grilles. The fixing frame and the fixing cover are screwed and installed by bolts to clamp the brick body therein to prevent the brick body from falling off during the rotation baking process.

[0012] Preferably, the flipping assembly includes a transmission block, a transmission shaft, and a transmission groove. Two transmission blocks are fixedly connected to the end of the connecting shaft. One end of the transmission shaft is connected to the transmission element of the high-temperature motor passing through the back plate of the furnace body. The other end of the transmission shaft is provided with a transmission groove that matches the transmission block. The transmission shaft is driven to rotate by the transmission element of the high-temperature motor, and the transmission block is driven to rotate together through the transmission groove on the transmission shaft, so that the rotation of the connecting shaft causes the fixed frame to drive the bricks to rotate, so that the bricks are heated more evenly during baking.

[0013] Preferably, the heating structure includes a heating bracket and a resistance heating device. A plurality of hollow heating brackets made of heat-resistant ceramics are fixedly connected to the top of the furnace body, and an arc-shaped resistance heating device is fixedly connected to the lower end of the heating bracket. By splitting the conventional large-volume resistance heating device into a combination of small-volume resistance heating devices, the additional economic cost due to the particularity of the production materials and production process of the large-volume heating device is saved. At the same time, it is more flexible to replace the damaged heating device, saving the economic cost of replacement and maintenance.

[0014] Beneficial effects of the utility model:

[0015] 1. The pull-out base assembly is in the form of a slide groove and a slider, which makes it easy for users to drag the base to load and unload bricks, saving space inside the baking device for loading and unloading bricks, shortening the distance between the heating device and the bricks, and improving baking efficiency. The movable support structure locks the position of the connecting rod through a limiting structure to prevent the bricks from shifting and causing the flip assembly to fail. The angle locking assembly locks the angle of the connecting rod through a pin connection to fix the position of the fixed frame, reducing the difficulty of loading and unloading the bricks. The brick fixing structure fixes the bricks by screwing the frame cover with bolts to prevent the bricks from falling during rotation baking. The flip assembly flips the bricks through the transmission element of the high-temperature motor, making the baking more uniform. Compared with the traditional large-scale integral heating structure, the detachable resistance heating device has smaller heating blocks, simpler manufacturing process, higher cost performance, saves economic costs and is easy to replace.

[0016] 2. The use of a retractable pull-out base saves the brick loading and unloading space inside the baking device, making the heating device closer to the brick body and improving the heating efficiency.

[0017] 3. By disassembling a large resistance heating device into small pieces for assembly, the economic cost of the large heating device due to the particularity of the production process and production materials is saved.

[0018] 4. The use of semi-enclosed heat pipes and high-temperature motors to rotate the bricks replaces the fully enclosed baking method, which allows the bricks to be heated evenly while also reducing the energy cost during baking. BRIEF DESCRIPTION OF THE DRAWINGS

By reducing the inner space of the aluminum silicon carbide carbon brick baking device, the heating tube is closer to the brick body, and a movable slide rail is added to the brick fixing structure, which facilitates the loading and unloading of the brick body and improves the heat utilization efficiency.

The horizontal position of the connecting shaft 303 is limited by the limit ring 302 to prevent the connecting shaft 303 from shifting and falling off when rotating with the transmission shaft 602, resulting in failure of the flip assembly 6.

[0029] See also Figure 4-5In this embodiment, the angle locking assembly 4 includes a fixing plate 401, a fixing pin 402, and a fixing bolt 403. A fixing plate 401 is fixedly connected to the side of the limit plate 304 near the handle 204.

The other end of the transmission shaft 602 is provided with a transmission groove 603 adapted to the transmission block 601. The heating structure 7 includes a heating bracket 701 and a resistance heating device 702. A plurality of hollow heating brackets 701 made of heat-resistant ceramics are fixedly connected to the top of the furnace body 1.
