[0001] This utility model relates to the field of heating structure technology, and in particular to an improved heating structure. Background Technology

[0002] Among the many devices that require heating, the performance and adaptability of the heating structure have a significant impact on the device's operational efficiency.

[0003] Traditional heating structures often suffer from problems such as fixed heating areas and insufficient heating stability. For example, in some industrial production processes, different processes may require heating different areas, but existing heating structures are unable to flexibly adjust the heating area to meet diverse needs. At the same time, during high-temperature heating, the stability and fixing method of the heating wire also affect the uniformity of heating and the service life of the equipment. Therefore, we propose an improved heating structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an improved heating structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An improved heating structure includes a ceramic main heat insulation plate, a ceramic secondary heat insulation plate slidably sleeved on the outer side of the ceramic main heat insulation plate, an annular plate fixedly installed on the inner wall of the ceramic secondary heat insulation plate, and fixing seats installed on the inner walls of both the annular plate and the ceramic main heat insulation plate. A high-temperature resistant alloy heating wire arranged in a spiral pattern is installed between the two fixing seats. Multiple T-shaped grooves with open tops are opened on the inner wall of the ceramic main heat insulation plate. T-shaped seats are slidably installed in the T-shaped grooves. A guide seat is fixedly installed on one side of the T-shaped seat. A guide hole is opened on the guide seat, and the alloy heating wire passes through the corresponding guide hole.

[0007] Preferably, the T-shaped seat has bolt holes, and the bolt holes are threaded with locking bolts for fixing the T-shaped seat.

[0008] Preferably, multiple horizontal plates are fixedly installed on the outer side of the main ceramic heat insulation plate, and a limiting mechanism is provided between the horizontal plates and the secondary ceramic heat insulation plate.

[0009] Preferably, the limiting mechanism includes a limiting groove and a limiting seat. The limiting groove is formed on the bottom of the ceramic secondary heat insulation plate, and the limiting seat is fixedly installed on the top of the horizontal plate, and the limiting seat is slidably connected to the corresponding limiting groove.

[0010] Preferably, a threaded rod is fixedly installed on the top of the horizontal plate, and multiple lifting plates are fixedly installed on the outer side of the ceramic auxiliary heat insulation plate, with the lifting plates sleeved on the threaded rod.

[0011] Preferably, the lifting plate has mounting holes, and the threaded rod passes through the corresponding mounting holes, with a limit plate installed at the top of the threaded rod.

[0012] Preferably, the threaded rod is provided with two threaded sleeves for fixing the lifting plate, and the lifting plate is located between the two corresponding threaded sleeves.

[0013] Preferably, the number of guide seats is set to four to six, and the four to six guide seats are arranged in a ring with equal spacing.

[0014] The beneficial effects of this utility model are:

[0015] 1. The high-temperature resistant alloy heating wire can be fixedly installed between the ceramic main heat insulation plate and the ceramic secondary heat insulation plate through the fixing base. The high-temperature alloy heating wire can heat the equipment to 750 degrees Celsius.

[0016] 2. By moving the lifting plate, the lifting plate is stretched upwards through the ring plate and fixed seat to the top of the alloy heating wire, thereby increasing the pitch of the alloy heating wire and thus increasing the heating area of ​​the equipment. The lifting plate can be fixed by the threaded sleeve.

[0017] 3. When the alloy heating wire is stretched upward, the guide seat can guide the alloy heating wire upward, which can increase the stability of the alloy heating wire extension.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses an improved heating structure.

[0026] Reference Figure 1-5 An improved heating structure includes a ceramic main heat insulation plate 101. A ceramic secondary heat insulation plate 102 is slidably sleeved on the outer side of the ceramic main heat insulation plate 101. An annular plate 103 is fixedly installed on the inner wall of the ceramic secondary heat insulation plate 102. Fixing seats 104 are installed on the inner walls of both the annular plate 103 and the ceramic main heat insulation plate 101. A high-temperature resistant alloy heating wire 105 arranged in a spiral is installed between the two fixing seats 104. Multiple T-shaped grooves 202 with open tops are opened on the inner wall of the ceramic main heat insulation plate 101. T-shaped seats 203 are slidably installed in the T-shaped grooves 202. A guide seat 201 is fixedly installed on one side of the T-shaped seat 203. A guide hole 204 is opened on the guide seat 201, and the alloy heating wire 105 passes through the corresponding guide hole 204.

[0027] In this embodiment, the T-shaped seat 203 has bolt holes 205, and locking bolts 206 for fixing the T-shaped seat 203 are installed in the internal threads of the bolt holes 205. This design allows the T-shaped seat 203 to be stably fixed in the T-groove 202 of the ceramic main heat insulation plate 101. After the alloy heating wire 105 is adjusted, the guide seat 201 and the T-shaped seat 203 can be tightened by the locking bolts 206 to prevent the position of the alloy heating wire 105 from changing due to equipment vibration or other external forces, which greatly improves the stability of the heating structure during operation.

[0028] In this embodiment, multiple horizontal plates 301 are fixedly installed on the outer side of the main ceramic heat insulation plate 101. A limiting mechanism is provided between the horizontal plates 301 and the secondary ceramic heat insulation plate 102. The limiting mechanism includes a limiting groove 302 and a limiting seat 303. The limiting groove 302 is formed on the bottom of the secondary ceramic heat insulation plate 102, and the limiting seat 303 is fixedly installed on the top of the horizontal plate 301. The limiting seat 303 is slidably connected to the corresponding limiting groove 302. This limiting mechanism effectively restricts the movement trajectory of the secondary ceramic heat insulation plate 102, ensuring that it remains stable during sliding and preventing the secondary ceramic heat insulation plate 102 from shifting or shaking. This, in turn, ensures that the alloy heating wire 105 installed between it and the main ceramic heat insulation plate 101 can be accurately positioned, improving the precision of the heating structure adjustment.

[0029] In this embodiment, a threaded rod 401 is fixedly installed on the top of the horizontal plate 301, and multiple lifting plates 402 are fixedly installed on the outer side of the ceramic auxiliary heat insulation plate 102. The lifting plates 402 are sleeved on the threaded rod 401, and the lifting plates 402 have mounting holes 403. The threaded rod 401 passes through the corresponding mounting holes 403. A limit plate 405 is installed at the top of the threaded rod 401. The threaded sleeve 404 on the threaded rod 401 has two threaded sleeves 404 for fixing the lifting plates 402, and the lifting plates 402 are located between the two corresponding threaded sleeves 404. This structure not only facilitates the operator to flexibly adjust the height of the lifting plates 402 by rotating the threaded sleeves 404, thereby precisely controlling the stretching degree of the alloy heating wire 105 and achieving precise adjustment of the heating area, but also ensures that the lifting plates 402 are firmly fixed by the threaded sleeves 404 after adjustment, thus improving the stability of the heating area after adjustment and enhancing the practicality and reliability of the heating structure.

[0030] In this embodiment, the number of guide seats 201 is set to four to six, and the four to six guide seats 201 are arranged in a ring with equal spacing. The multiple guide seats 201 are distributed in a ring with equal spacing, which can provide stable guidance to the alloy heating wire 105 from multiple directions. During the stretching of the alloy heating wire 105 or the operation of the equipment, it can effectively prevent the alloy heating wire 105 from twisting, bending unevenly, etc., and ensure that the alloy heating wire 105 remains stable during the extension process, further ensuring the uniformity and stability of heating and extending the service life of the alloy heating wire 105.

[0031] In this invention, a high-temperature resistant alloy heating wire 105 is fixedly installed between the ceramic main heat insulation plate 101 and the ceramic secondary heat insulation plate 102 via a fixing base 104. The high-temperature alloy heating wire 105 can heat the equipment to 750 degrees Celsius. When different areas need to be heated, the lifting plate 402 is moved. The lifting plate 402, via the annular plate 103 and the fixing base 104, pulls the top of the alloy heating wire 105 upwards, thereby increasing the pitch of the alloy heating wire 105 and thus increasing the heating area of ​​the equipment. By rotating the threaded sleeve 404, the threaded sleeve 40... 4. While rotating and moving on the threaded rod 401, when the corresponding two threaded sleeves 404 move towards the lifting plate 402, the lifting plate 402 can be fixed by the two threaded sleeves 404. When the alloy heating wire 105 is stretched upward, the guide seat 201 can guide the alloy heating wire 105 upward, which can increase the stability of the extension of the alloy heating wire 105. By rotating the locking bolt 206, the locking bolt 206 can be in close contact with the ceramic main heat insulation plate 101, which can fix the guide seat 201 and strengthen the extended alloy heating wire 105.

[0032] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
