Technical Field
[0001] This utility model relates to the field of ceramic fiber resistance furnaces, specifically a ceramic fiber resistance furnace. Background Technology
[0002] Ceramic fiber resistance furnaces are high-temperature heating devices made of ceramic fiber as the insulation material. They possess excellent heat insulation and high-temperature resistance, effectively reducing heat loss within the furnace and improving its thermal efficiency. They typically consist of a furnace body, heating elements, and a temperature control system. The heating elements, usually made of resistance wire or similar materials, convert electrical energy into heat energy, raising the temperature inside the furnace to achieve the heating purpose. The temperature control system comprises a temperature sensor, a temperature controller, and heating elements. The temperature sensor detects the temperature inside the furnace, the temperature controller regulates the temperature, and the heating elements raise the temperature within the furnace. They are widely used in production and experimentation in fields such as ceramics, metallurgy, electronics, glass, chemicals, machinery, refractory materials, new material development, special materials, and building materials.
[0003] The existing equipment has the following shortcomings when in use: the placement plates in the furnace cavity are mostly fixedly installed, or the adjustment of the placement plates is fixed at fixed points and layers, which makes it inconvenient to accurately adjust the position of the placement plates according to the size of different workpieces, affecting the utilization efficiency of the space in the furnace cavity and reducing the practicality of the resistance furnace. Utility Model Content
[0004] The purpose of this invention is to provide a ceramic fiber resistance furnace to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a ceramic fiber resistance furnace, comprising a furnace shell, a base, a door, an adjusting rod, a placement plate, and a moving ring. The furnace shell has a furnace cavity, in which an adjusting rod is installed. A moving ring is slidably fitted onto the adjusting rod. A slider is installed on the inner wall of the moving ring. A groove is formed on the outer wall of the adjusting rod, and the slider is slidably connected to the groove. A lead screw is threaded onto the moving ring, and a fixing block is rotatably mounted at one end of the lead screw. The fixing block is located inside the inner ring of the moving ring. A connecting plate is installed on the moving ring, and a placement plate is placed on the connecting plate. The placement plate is fixedly connected to the connecting plate via a fixing rod.
[0006] By adopting the above technical solution, the slider installed on the inner wall of the moving ring slides in conjunction with the groove opened on the outer wall of the adjusting rod. The moving ring is then placed on the adjusting rod. After adjusting the position of the moving ring on the adjusting rod, the screw threaded on the moving ring is rotated, causing the fixed block installed at the other end of the screw to move and abut against the adjusting rod, thus limiting and fixing the moving ring. Then, the placement plate is placed on the connecting plate installed on the moving ring, and a fixing rod is used to fix the placement plate through the connecting plate, which facilitates the installation and disassembly of the placement plate. This allows the position of the placement plate to be precisely adjusted according to the size of the workpiece, improving the utilization efficiency of the furnace cavity space and enhancing the practicality of the resistance furnace.
[0007] Preferably, a base is installed at the bottom of the resistance furnace box shell, a threaded rod is threaded onto the base, a handle is installed at the top of the threaded rod, and a caster wheel is rotatably installed at the bottom of the threaded rod.
[0008] By adopting the above technical solution, rotating the handle on the threaded rod causes the threaded rod, which is threaded onto the base, to rotate. This causes the threaded rod to move up and down on the base, which in turn moves the caster at the bottom of the threaded rod up and down. When the caster at the bottom of the threaded rod contacts the ground, the resistance furnace box can be moved. This allows for easy movement of the resistance furnace box according to usage needs, increasing its flexibility. Once the resistance furnace box is in the appropriate position, rotating the handle on the threaded rod in the opposite direction causes the threaded rod to move the caster at the bottom upwards until the caster is fully retracted into the base. This prevents the resistance furnace box from moving during use and increases its stability when placed.
[0009] Preferably, a fixed shaft is installed on the outer shell of the resistance furnace box, an mounting plate is installed on the box door, the mounting plate is rotatably connected to the fixed shaft, an insert is installed on the box door, a door lock block is installed on the outer shell of the resistance furnace box, a slot is opened on the door lock block, the insert is fitted into the slot, and a plug is inserted into the door lock block and the insert.
[0010] By adopting the above technical solution, the door can rotate around the fixed shaft through the rotatable connection between the fixed shaft and the mounting plate, which facilitates the opening and closing of the door. When the door is closed, the plug on the door will be inserted into the slot on the door lock block. Then, the plug rod is inserted into the door lock block and the plug block to fix the door to the outer shell of the resistance furnace, which prevents the door from being accidentally opened during the operation of the resistance furnace and improves the safety of the resistance furnace during use.
[0011] Preferably, the inner wall of the furnace cavity is provided with heating pipes, the outer wall of the furnace cavity is provided with a ceramic fiber layer, and a heat insulation layer is provided between the ceramic fiber layer and the outer shell of the resistance furnace box.
[0012] Using the above technical solution, the heating tubes are used to provide the heating energy required by the resistance furnace, ensuring that the temperature inside the furnace cavity can reach the predetermined process requirements. The ceramic fiber layer has good high temperature resistance and heat insulation effect, which can effectively reduce heat loss inside the furnace cavity, improve heating efficiency and save energy. At the same time, the setting of the insulation layer further enhances the heat insulation performance of the furnace cavity, enabling the resistance furnace to maintain a stable temperature environment during operation, which is conducive to improving the heat treatment quality of the workpiece and production efficiency.
[0013] Preferably, the material of the placement plate adjustment structure in the outer shell of the resistance furnace box is a nickel-based alloy.
[0014] By employing the above technical solution, the nickel-based alloy exhibits excellent high-temperature resistance, corrosion resistance, and high strength, enabling the placement plate adjustment structure to maintain stable performance under the high-temperature operating environment of the resistance furnace, and preventing deformation or damage. This improves the reliability and durability of the resistance furnace.
[0015] Preferably, a control panel and a temperature control system are installed on the outer shell of the resistance furnace.
[0016] Using the above technical solution, the control panel is used to operate the various functions of the resistance furnace, while the temperature control system is responsible for controlling the temperature inside the furnace cavity to ensure the stability and accuracy of the furnace cavity temperature.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. Place the moving ring on the adjusting rod. After adjusting the position of the moving ring, rotate the screw threaded on the moving ring to move the fixed block at the other end of the screw to abut against the adjusting rod, thus limiting and fixing the moving ring. Then place the placement plate on the connecting plate installed on the moving ring. This allows the position of the placement plate to be precisely adjusted according to the size of the workpiece, improving the utilization efficiency of the furnace cavity space and enhancing the practicality of the resistance furnace.
[0019] 2. By rotating the handle on the threaded rod, the universal wheel at the bottom of the threaded rod moves up and down. When the universal wheel at the bottom of the threaded rod contacts the ground, the resistance furnace box can be moved, making it easy for people to move the resistance furnace box according to their needs, increasing the flexibility of the resistance furnace box. After the resistance furnace box is moved to a suitable position, rotate the handle on the threaded rod in the opposite direction, causing the threaded rod to move the universal wheel at the bottom upward until the universal wheel is completely retracted into the base, preventing the resistance furnace box from moving during use and increasing the stability of the resistance furnace box when placed.

[0025] 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.
[0026] Please see Figure 1-4This utility model provides an embodiment of a ceramic fiber resistance furnace, comprising a furnace shell 1, a base 2, a door 6, an adjusting rod 15, a placement plate 16, and a moving ring 17. The furnace shell 1 has a furnace cavity 12, in which the adjusting rod 15 is installed. The moving ring 17 is slidably fitted onto the adjusting rod 15. A slider 23 is installed on the inner ring wall of the moving ring 17. A groove 22 is formed on the outer wall of the adjusting rod 15, and the slider 23 is slidably connected to the groove 22. A lead screw 18 is threaded onto the moving ring 17, and a fixing block 19 is rotatably installed at one end of the lead screw 18. The fixing block 19 is located inside the inner ring of the moving ring 17. A connecting plate 20 is installed on the moving ring 17, and the placement plate 16 is placed on the connecting plate 20. The placement plate 16 is fixedly connected to the connecting plate 20 via a fixing rod 21. The slider 23 installed on the inner ring wall of the moving ring 17 slides in conjunction with the groove 22 opened on the outer wall of the adjusting rod 15. The moving ring 17 is then placed on the adjusting rod 15. After adjusting the position of the moving ring 17 on the adjusting rod 15, the screw 18 threaded on the moving ring 17 is rotated, causing the fixing block 19 installed at the other end of the screw 18 to move and abut against the adjusting rod 15, thus limiting and fixing the moving ring 17. Then, the placement plate 16 is placed on the connecting plate 20 installed on the moving ring 17. The fixing rod 21 passes through the placement plate 16 and the connecting plate 20 to fix it, which facilitates the installation and disassembly of the placement plate 16. The position of the placement plate 16 can be precisely adjusted according to the size of the workpiece, improving the utilization efficiency of the furnace cavity space and enhancing the practicality of the resistance furnace.
[0027] The bottom of the resistance furnace box shell 1 is equipped with a base 2. A threaded rod 3 is threaded onto the base 2. A handle 4 is installed at the top of the threaded rod 3, and a caster wheel 5 is rotatably installed at the bottom of the threaded rod 3. By rotating the handle 4 on the threaded rod 3, the threaded rod 3 on the base 2 rotates, causing the threaded rod 3 to move up and down on the base 2. This moves the caster wheel 5 at the bottom of the threaded rod 3 up and down. When the caster wheel 5 at the bottom of the threaded rod 3 contacts the ground, the resistance furnace box can be moved. This allows for easy movement of the resistance furnace box according to usage needs, increasing its flexibility. After the resistance furnace box is moved to a suitable position, the handle 4 on the threaded rod 3 is rotated in the opposite direction, causing the threaded rod 3 to move the caster wheel 5 upwards until the caster wheel 5 is completely retracted into the base 2. This prevents the resistance furnace box from moving during use and increases its stability when placed.
[0028] A fixed shaft 7 is installed on the outer shell 1 of the resistance furnace box, and an mounting plate 8 is installed on the door 6. The mounting plate 8 is rotatably connected to the fixed shaft 7. A plug 9 is installed on the door 6, and a door lock block 10 is installed on the outer shell 1 of the resistance furnace box. The door lock block 10 has a slot 24, and the plug 9 fits into the slot 24. A plug rod 11 is inserted into the door lock block 10 and the plug 9. The rotatable connection between the fixed shaft 7 and the mounting plate 8 allows the door 6 to rotate around the fixed shaft 7, facilitating the opening and closing of the door 6. When the door 6 is closed, the plug 9 on the door 6 is inserted into the slot 24 on the door lock block 10, and then the plug rod 11 is inserted into the door lock block 10 and the plug 9, fixing the door 6 to the outer shell 1 of the resistance furnace box. This prevents the door 6 from accidentally opening during the operation of the resistance furnace box and improves the safety of the resistance furnace during use.
[0029] Heating tubes 13 are installed on the inner wall of the furnace cavity 12, and a ceramic fiber layer 14 is installed on the outer wall of the furnace cavity 12. An insulation layer is installed between the ceramic fiber layer 14 and the outer shell 1 of the resistance furnace. The heating tubes 13 provide the heating energy required by the resistance furnace, ensuring that the temperature inside the furnace cavity 12 can reach the predetermined process requirements. The ceramic fiber layer 14 has good high-temperature resistance and heat insulation effect, which can effectively reduce heat loss inside the furnace cavity 12, improve heating efficiency and save energy. At the same time, the insulation layer further enhances the heat insulation performance of the furnace cavity 12, enabling the resistance furnace to maintain a stable temperature environment during operation, which is beneficial to improving the heat treatment quality of the workpiece and production efficiency.
[0030] The placement plate adjustment structure in the outer shell 1 of the resistance furnace is made of a nickel-based alloy. Nickel-based alloys possess excellent high-temperature resistance, corrosion resistance, and high strength, enabling the placement plate adjustment structure to maintain stable performance under the high-temperature operating environment of the resistance furnace, preventing deformation or damage. This improves the reliability and durability of the resistance furnace.
[0031] The resistance furnace housing 1 is equipped with a control panel and a temperature control system. The control panel is used to operate various functions of the resistance furnace, while the temperature control system is responsible for controlling the temperature inside the furnace cavity to ensure the stability and accuracy of the furnace cavity temperature.
[0032] The control system and heating components involved in this application are all existing mature technologies, and there are many products on the market. They are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or through routine use. The protection content of this application does not involve improvements to the control system and heating components, so the model of the heating components and the control process of the control system will not be described in detail here.
[0033] Working principle: The slider 23 installed on the inner ring wall of the moving ring 17 slides and engages with the groove 22 on the outer wall of the adjusting rod 15, so that the moving ring 17 is fitted onto the adjusting rod 15. After adjusting the position of the moving ring 17 on the adjusting rod 15, the screw 18 threaded on the moving ring 17 is rotated, causing the fixing block 19 installed at the other end of the screw 18 to move and abut against the adjusting rod 15, thus limiting and fixing the moving ring 17. Then, the placement plate 16 is placed on the connecting plate 20 installed on the moving ring 17, and the fixing rod 21 passes through the placement plate 16 and the connecting plate 20 to fix it, which facilitates the installation and removal of the placement plate 16. The position of the placement plate 16 can be precisely adjusted according to the size of the workpiece, which improves the utilization efficiency of the furnace cavity space and enhances the practicality of the resistance furnace. The workpiece to be heated is placed on the adjusted placement plate 16, and then the box door 6 is closed, so that the insert block 9 on the box door 6 is inserted into the door lock block 10. The door 6 is inserted into the slot 24 on the upper part of the furnace, and then the plug rod 11 is inserted into the door lock block 10 and the plug block 9 to fix the door 6 to the outer shell 1 of the resistance furnace box. This prevents the door 6 from being accidentally opened during the operation of the resistance furnace box and improves the safety of the resistance furnace during use. By turning the handle 4 on the threaded rod 3, the threaded rod 3 installed on the base 2 is rotated, so that the threaded rod 3 moves up and down on the base 2, driving the universal wheel 5 at the bottom of the threaded rod 3 to move up and down. When the universal wheel 5 at the bottom of the threaded rod 3 contacts the ground, the resistance furnace box can be moved, which is convenient for people to move the resistance furnace box according to the needs of use and increases the flexibility of the resistance furnace box. When the resistance furnace box is moved to a suitable position, the handle 4 on the threaded rod 3 is turned in the opposite direction, so that the threaded rod 3 drives the universal wheel 5 at the bottom to move up until the universal wheel 5 is completely retracted into the base 2, preventing the resistance furnace box from moving during use and increasing the stability of the resistance furnace box when placed.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
