Description

Technical Field

[0001] This utility model relates to the field of heating tube insulation and monitoring technology, and in particular to a heating tube insulation end cap and aging monitoring structure. Background Technology

[0002] In traditional heating equipment, the heating element is a core component, and its performance directly affects the heating efficiency and energy consumption of the equipment. However, after prolonged operation, the heating element gradually ages due to material fatigue, oxidation, and other reasons, leading to a decrease in thermal efficiency and even safety hazards. Simultaneously, the heat generated by the heating element is often directly transferred to the heating chamber or the surrounding environment through the end cap, causing unnecessary energy loss. Existing solutions mostly rely on complex intelligent control systems for monitoring and control, which not only increases equipment costs but may also affect monitoring accuracy due to system failures. Therefore, developing a simple, externally power-free, and automatically monitoring-the-aging state of the heating element with an insulated end cap structure is particularly important.

[0003] In existing technologies, the structural design of the heat insulation end cap for heating tubes is relatively simple, often using single-layer or simple multi-layer materials, resulting in limited heat insulation performance and difficulty in maintaining efficient heat insulation effects over a long period. Furthermore, there is a lack of effective real-time monitoring methods for the aging and deformation of the heat insulation end cap, making it difficult to promptly detect and address potential safety hazards, thus reducing its practicality. Therefore, this utility model discloses a heat insulation end cap for heating tubes and an aging monitoring structure to solve the problem of the difficulty in detecting aging and damage of the heat insulation end cap after long-term use, and the safety hazards caused by the failure to detect and replace it in a timely manner. Utility Model Content

A trigger cylinder is installed at the middle of the top end of the pressing plate, and a trigger plate is slidably installed on the inner top wall of the mounting ring. A limiting protrusion is installed on the side wall of the mounting ring located at the bottom wall position of the trigger plate.

[0009] Preferably, the triggering component includes a threaded sleeve, the bottom end of which is mounted on the upper end face of the triggering plate, and a threaded screw is mounted on the upper end of the threaded sleeve. The threads of the threaded sleeve and the threaded screw are engaged, and a drive gear is mounted on the top end of the threaded screw.

[0010] Preferably, multiple sets of mounting brackets are installed on the upper part of the driving gear, and a rotating shaft is installed on the bottom wall of the middle part of the multiple sets of mounting brackets.

[0012] The beneficial effects of this utility model are:

[0013] By employing a multi-layer composite material design, including a hydrophobic layer, a heat insulation layer, and a sealing layer, the thermal insulation performance of the heat-insulating end cap is effectively improved, reducing heat transfer to the surrounding environment, thereby increasing the thermal efficiency of the heating element and reducing energy consumption. This invention features a unique deformation monitoring mechanism that cleverly combines a compression spring, a transverse guide rod, and a trigger assembly to monitor the deformation state of the heat-insulating end cap in real time.

During maintenance, the condition of the heat-insulating end cap can be determined simply by observing changes in the observation slit, without disassembling the equipment, reducing maintenance difficulty and cost.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] This utility model provides, for example Figures 1 to 5The heating element insulation end cap and aging monitoring structure shown includes: a heating element 1, a fixing ring 2 installed on the top side wall of the heating element 1, and an insulation end cap 6 installed on the top of the heating element 1. An installation ring 5 is installed on the upper end of the insulation end cap 6, and a housing 7 is installed on the upper part of the installation ring 5. Two sets of fixing rods 4 are installed on the side wall of the housing 7. The lower end of the fixing rod 4 is installed on the fixing ring 2, and a limiting hole 3 is opened on the fixing ring 2 corresponding to the position of the fixing rod 4. The end of the fixing rod 4 is engaged in the limiting hole 3. Multiple sets of observation slits 8 are evenly opened on the top and side wall of the housing 7. Multiple sets of composite materials are installed inside the insulation end cap 6, and a triggering component is installed inside the housing 7. The triggering component is used to monitor the deformation state of the insulation end cap 6. By adopting a multi-layer composite material design, including a hydrophobic layer 10, a heat insulation layer 26, and a sealing layer 27, the heat insulation performance of the insulation end cap 6 is effectively improved, the heat transfer to the surrounding environment is reduced, thereby improving the thermal efficiency of the heating element 1 and reducing energy consumption. This invention features a unique deformation monitoring mechanism that cleverly combines a compression spring 11, a transverse guide rod 13, and a trigger assembly to monitor the deformation state of the heat insulation end cap 6 in real time. Once the heat insulation end cap 6 deforms due to aging, material fatigue, or other reasons, the monitoring structure will respond immediately, issuing a clear warning by observing changes in the seam 8. This facilitates timely detection and intervention by maintenance personnel, effectively preventing safety hazards caused by the failure of the heat insulation end cap 6. The use of a mechanical monitoring principle avoids the problem of monitoring accuracy being affected by system failures, thus improving practicality. The heat insulation end cap 6 of the heating element 1 and the aging monitoring structure are easy to install, requiring no complex debugging process. During maintenance, the condition of the heat insulation end cap 6 can be determined simply by observing changes in the seam 8, without disassembling the equipment, reducing maintenance difficulty and cost.

[0025] Furthermore, in this example, such as Figure 2 and Figure 4As shown, a hydrophobic layer 10 is installed on the inner wall of the top of the heat insulation end cap 6, a heat insulation layer 26 is installed at the lower end of the hydrophobic layer 10, and a sealing layer 27 is installed at the lower end of the heat insulation layer 26. The lower end of the sealing layer 27 is installed on the inner wall of the bottom of the heat insulation end cap 6. A compression spring 11 is installed in the middle of the top of the heat insulation end cap 6, and a pressing plate 12 is installed at the top of the compression spring 11. Transverse guide rods 13 are installed on the corresponding two side walls of the pressing plate 12. A sliding guide rod 28 is slidably inserted into the side wall of the transverse guide rod 13 away from the pressing plate 12. A telescopic spring 29 is sleeved on the sliding guide rod 28. A directional wheel assembly 30 is installed at the other end of the sliding guide rod 28, and a sliding groove 9 is opened on the inner wall of the mounting ring 5 corresponding to the position of the transverse guide rod 13. The top end of the telescopic spring 29 abuts against the side wall of the transverse guide rod 13, and the bottom end of the telescopic spring 29 abuts against the upper side wall of the directional wheel assembly 30. The pulley of the directional wheel assembly 30 abuts against the bottom wall of the sliding groove 9, and a limiting arc slope 31 is installed on the bottom wall of the sliding groove 9. The limiting arc slope 31 is located below the top end of the mounting ring 5 on the bottom wall of the sliding groove 9. A trigger cylinder 16 is installed at the middle of the top end of the pressing plate 12. A trigger plate 14 is slidably installed on the inner top wall of the mounting ring 5. A limiting protrusion is installed on the side wall of the mounting ring 5 at the position of the bottom wall of the trigger plate 14. When the heating tube is working, if the heat insulation end cap 6 deforms due to thermal expansion or other reasons, it will squeeze the compression spring 11 at its upper end. The compression spring 11 is compressed after being subjected to force, which at the same time drives the pressing plate 12 and the transverse guide rod 13 at its upper end to move upward. Because the directional wheel assembly 30 at the end of the transverse guide rod 13 is blocked by the limiting arc slope 31 of the inner wall of the mounting ring 5, when the heat insulation end cap 6 deforms to a certain extent, the compression spring 11, the pressing plate 12, and the transverse guide rod 13 will store a large amount of energy. Once the deformation exceeds the critical point, the compression spring 11 will rapidly release the energy, causing the pressing plate 12 and the transverse guide rod 13 to spring upwards instantaneously. At this time, the transverse guide rod 13 will impact and push the trigger plate 14 upwards, thereby triggering the subsequent monitoring and response mechanism.

[0026] Furthermore, in this example, such as Figure 2 , Figure 3 and Figure 5As shown, the trigger assembly includes a threaded sleeve 15. The bottom end of the threaded sleeve 15 is mounted on the upper surface of the trigger plate 14. A threaded screw 17 is mounted on the upper end of the threaded sleeve 15. The threads of the threaded sleeve 15 and the threaded screw 17 are engaged. A drive gear 18 is mounted on the top end of the threaded screw 17. Multiple sets of mounting brackets 20 are mounted on the upper part of the drive gear 18. A rotating shaft 25 is mounted on the bottom wall of the middle part of the multiple sets of mounting brackets 20. A driven gear 19 is mounted on the rotating shaft 25. The outer edge of the drive gear 18 is engaged with the outer edge of the driven gear 19. A groove is opened on the side wall of the multiple sets of mounting brackets 20 away from the rotating shaft 25. A sliding telescopic rod 21 is slidably inserted into the groove. An arc-shaped connecting plate is mounted on the other end of the sliding telescopic rod 21. 24. The outer walls of the arc-shaped connecting plates 24 are all installed on the inner walls of the housing 7. Multiple sets of arc-shaped guide rails 22 are provided at the upper and lower ends of the driven gear disk 19. The arc-shaped guide rails 22 are arranged obliquely from the middle of the driven gear disk 19 to the outer edge of the driven gear disk 19. Sliding rods are slidably inserted into each set of arc-shaped guide rails 22. A limit block 23 is installed at the end of the sliding rod away from the mounting bracket 20, and the end of the sliding rod close to the mounting bracket 20 is installed on a sliding telescopic rod 21 that is slidably inserted into the mounting bracket 20. The mounting bracket 20 has a through rectangular groove with the same width as the diameter of the sliding rod at the end of the sliding rod. When the trigger plate 14 is pushed upward by the transverse guide rod 13, the threaded sleeve 15 at its upper end also moves accordingly. Since the threaded sleeve 15 is engaged with the threaded screw 17, the threaded screw 17 will rotate as the threaded sleeve 15 moves. A drive gear 18 is mounted at the top of the threaded screw 17, and the drive gear 18 engages with the outer edge of the driven gear disk 19 on the mounting bracket 20. Therefore, when the drive gear 18 rotates, it will drive the driven gear disk 19 to rotate as well. Multiple sets of arc-shaped guide rails 22 are provided at both the upper and lower ends of the driven gear disk 19, and these arc-shaped guide rails 22 rotate with the rotation of the driven gear disk 19. The sliding rod slides within the arc-shaped guide rails 22, thereby pushing the sliding telescopic rod 21, mounted at the other end of the sliding rod, to expand outward within the groove of the mounting bracket 20. Since the other end of the sliding telescopic rod 21 is connected to the inner wall of the housing 7 through the arc-shaped connecting plate 24, when the sliding telescopic rod 21 expands outward, it will cause the housing 7 to deform, resulting in a larger gap in the observation slit 8. At this time, the observer can directly see the change in the observation slit 8, thereby determining the deformation state of the heat insulation end cover 6 and taking corresponding measures for monitoring and maintenance.
