Description

Technical Field

[0001] This utility model relates to the field of boiler safety monitoring technology, specifically to a wall temperature monitoring device for high-temperature tube panels in boilers. Background Technology

[0002] In industrial production, boilers, as crucial energy conversion equipment, directly impact the safety and economy of the entire production system through their operational status. During boiler operation, the high-temperature tube panel, as the core component carrying the heat exchange of high-temperature flue gas and working fluid, requires careful monitoring of its wall temperature to ensure safe and stable boiler operation. Because the boiler interior is constantly exposed to high temperatures and pressures, abnormal temperature fluctuations in the tube panel wall can indicate potential safety hazards. Overheating can lead to changes in the metallographic structure of the tubes, and long-term operation can cause creep damage. Severe burn-out can result in tube panel rupture, leading to leakage of high-temperature, high-pressure media. These problems not only reduce boiler thermal efficiency and shorten equipment lifespan but, in more serious cases, can even cause major safety accidents such as furnace explosions, resulting in incalculable casualties and property losses. Therefore, real-time monitoring of the boiler's high-temperature tube panel wall temperature is of paramount importance.

[0003] However, traditional wall temperature monitoring methods typically involve installing the temperature monitor in a threaded hole on the boiler surface. During the monitoring of the boiler's high-temperature tube panels, impurities generated inside the boiler can adhere to the surface of the temperature monitor's sensor probe. This necessitates periodically disassembling the temperature monitor to clean the sensor probe surface in order to maintain accurate temperature monitoring. However, the disassembly and installation process usually involves using tools such as wrenches to tighten and loosen bolts, which is time-consuming and labor-intensive, causing considerable inconvenience to the maintenance of the temperature monitor. Utility Model Content

[0004] The purpose of this utility model is to provide a wall temperature monitoring device for high-temperature tube panels in boilers, in order to solve the problem that in the existing technology, during the disassembly and installation process, tools such as wrenches are usually used to tighten and loosen bolts, which is time-consuming and laborious, and brings a lot of inconvenience to the maintenance of temperature monitoring instruments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wall temperature monitoring device for a boiler high-temperature tube panel, comprising:

[0006] The mounting mechanism and the temperature monitoring mechanism mounted on the mounting mechanism;

[0007] The installation mechanism includes a nut, a locking sleeve is fixedly connected to the top of the nut, a locking groove is provided inside the locking sleeve, an inlet and outlet communicating with the locking groove is provided on the top of the locking sleeve, a limit ring is installed on the top of the locking sleeve, and a locking block extending into the locking groove is fixedly installed at the bottom of the limit ring.

[0008] The temperature monitoring mechanism includes a mounting base inserted into the locking sleeve. A temperature monitoring instrument is fixedly installed on the top of the mounting base. A locking pin is fixedly connected to the periphery of the mounting base. The locking pin engages between the locking groove and the locking block. A temperature sensor probe is installed on the bottom of the mounting base via a fixed base.

[0009] Furthermore, a threaded seat is fixedly installed at the bottom of the nut, and the fixed seat extends into the interior of the threaded seat.

[0010] Furthermore, a sealing ring is installed on the periphery of the fixing seat to fit against the inner wall of the nut. The sealing ring is made of rubber material, and a swivel plate is fixedly installed on the periphery of the mounting seat.

[0011] Furthermore, a protective sleeve is fixedly connected to the bottom of the threaded seat, and the temperature sensor probe extends into the protective sleeve.

[0012] Furthermore, the top of the limiting ring has an opening, which corresponds to the inlet and outlet.

[0013] Furthermore, the top of the locking sleeve has a movable cavity, and an elastic element is fixedly connected between the movable cavity and the limiting ring.

[0014] Compared with existing technologies, this utility model provides a wall temperature monitoring device for high-temperature tube panels in boilers. By incorporating an installation mechanism, the device can be pre-installed on the temperature monitoring mounting holes on the boiler. When installation is required, simply insert the mounting base into the locking sleeve, allowing the locking pin to be inserted into the inlet / outlet. Rotating the mounting base moves the locking pin into the locking groove, where a locking block prevents it from detaching, thus allowing for quick installation. For disassembly, simply move the limit ring upwards, simultaneously moving the locking block upwards to separate it from the locking pin. Reverse rotation of the mounting base moves the locking pin to the inlet / outlet position, allowing it to be easily lifted out. This enables the mounting base to be quickly removed from the locking sleeve, facilitating rapid disassembly of the temperature monitoring device. The entire process eliminates the need for wrenches or other tools for tightening and loosening bolts, effectively saving installation and disassembly time and providing greater convenience for temperature monitoring device maintenance.

[0015] By installing a sealing ring around the fixed seat, it is possible to effectively prevent impurities and high-temperature gases from entering the threaded seat, thus avoiding leakage of these substances from the boiler. This also ensures the accuracy of temperature monitoring and extends the service life of the equipment. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] Example 1:

[0027] This utility model provides a wall temperature monitoring device for a boiler high-temperature tube panel, comprising:

[0028] Installation mechanism 2 and temperature monitoring mechanism 1 mounted on installation mechanism 2;

[0029] The mounting mechanism 2 includes a nut 21, a locking sleeve 24 fixedly connected to the top of the nut 21, a locking groove 28 is provided inside the locking sleeve 24, an inlet and outlet 27 communicating with the locking groove 28 is provided on the top of the locking sleeve 24, a limit ring 25 is installed on the top of the locking sleeve 24, and a locking block 26 extending into the locking groove 28 is fixedly installed at the bottom of the limit ring 25.

[0030] The temperature monitoring mechanism 1 includes a mounting base 12 inserted into the locking sleeve 24. A temperature monitoring instrument 11 is fixedly installed on the top of the mounting base 12. A locking pin 14 is fixedly connected to the periphery of the mounting base 12. The locking pin 14 engages between the locking groove 28 and the locking block 26. A temperature sensor probe 17 is installed on the bottom of the mounting base 12 through a fixing base 15.

[0031] As can be seen from the above, by fixing the nut 21 to the temperature monitoring mounting hole on the boiler during use, the mounting mechanism 2 can be pre-installed and fixed. During subsequent maintenance, there is no need to disassemble the mounting mechanism 2. When installing the temperature monitoring mechanism 1, the temperature sensor probe 17 is inserted into the nut 21, allowing the temperature sensor probe 17 to extend into the boiler. By aligning the locking pin 14 with the inlet / outlet 27, the locking pin 14 can be inserted into the inlet / outlet 27. Simultaneously, the mounting base 12 can be inserted into the locking sleeve 24. By rotating the mounting base 12, the locking pin 14 moves into the locking groove 28. The surface of the locking block 26 is inclined. When the locking pin 14 presses against the locking block 26, it can push the locking block 26 upward, allowing the locking pin 14 to move smoothly into the locking groove 28. When the locking pin 14 is separated from the locking block 26, the locking block 26 can move downward automatically, forming a blocking effect on the locking pin 14 and locking it in the locking groove 28. This prevents the mounting base 12 from coming off and allows for quick installation of the temperature monitoring mechanism 1. The temperature sensor probe 17 can be used to conveniently monitor the wall temperature of the high-temperature tube screen in the boiler. The monitored temperature data can be transmitted to the temperature monitoring instrument 11 for display, allowing staff to understand the wall temperature of the high-temperature tube screen in the boiler in a timely manner.

[0032] When disassembling the temperature monitoring mechanism 1, moving the limit ring 25 upwards will simultaneously move the locking block 26 upwards, releasing the blocking effect of the locking block 26 on the locking pin 14. By operating the mounting base 12 to rotate in the opposite direction, the locking pin 14 can be moved to the inlet / outlet 27 position, making it easy to lift the locking pin 14 upwards along the inlet / outlet 27. At the same time, the mounting base 12 can be quickly removed from the locking sleeve 24, allowing for rapid disassembly of the temperature monitoring mechanism 1. The entire process does not require the use of wrenches or other tools to tighten or loosen bolts, effectively saving installation and disassembly time. It also facilitates the cleaning of impurities adhering to the surface of the temperature sensor probe 17, bringing greater convenience to the maintenance of the temperature monitoring mechanism 1.

[0033] From the appendix Figure 1 and attached Figure 5 It can be seen that a threaded seat 22 is fixedly installed at the bottom of the nut 21, and the fixing seat 15 extends into the threaded seat 22.

[0034] As can be seen from the above, the threaded seat 22 can be conveniently installed on the temperature monitoring point on the boiler, and the installation mechanism 2 can be conveniently pre-installed and fixed without subsequent disassembly. When installing the temperature monitoring mechanism 1, the fixing seat 15 can extend into the interior of the threaded seat 22, which can make the temperature sensor probe 17 more securely installed on the boiler, avoiding the temperature sensor probe 17 from loosening or shifting due to vibration during boiler operation, thereby ensuring the accuracy and stability of temperature monitoring.

[0035] For details, please refer to the appendix. Figure 1 and attached Figure 5 As shown, a sealing ring 16 that fits against the inner wall of the nut 21 is installed on the periphery of the fixing base 15. The sealing ring 16 is made of rubber material. A swivel plate 13 is fixedly installed on the periphery of the mounting base 12.

[0036] As can be seen from the above, the sealing ring 16 made of rubber material can fit against the inner wall of the threaded seat 22. The double-layer sealing ring 16 can effectively improve the sealing effect and form an effective physical barrier layer to prevent the leakage of high-temperature flue gas and dust particles inside the boiler. At the same time, the elastic deformation characteristics of the rubber material can compensate for the small gaps that may occur during the installation process, ensuring the durability of the sealing effect. The plum blossom plate 13 allows the operator to easily rotate the mounting seat 12.

[0037] For details, please refer to the appendix. Figure 5 As shown, a protective sleeve 23 is fixedly connected to the bottom of the threaded seat 22, and the temperature sensor probe 17 extends into the protective sleeve 23.

[0038] As can be seen from the above, the protective sleeve 23 is made of high temperature and corrosion resistant alloy material, and its interior has a cavity that matches the shape of the temperature sensor probe 17. This provides all-round physical protection for the temperature sensor probe 17, effectively preventing molten slag or high temperature particles splashed inside the boiler from directly impacting the temperature sensor probe 17, and extending the service life of the temperature sensor probe 17 under harsh working conditions.

[0039] Working principle: By securely installing the nut 21 with the threaded seat 22 onto the pre-set temperature monitoring mounting hole on the boiler, the pre-fixation of the mounting mechanism 2 is completed. When the temperature monitoring mechanism 1 needs to be installed, the operator holds the mounting base 12, aligns the temperature sensor probe 17 with the inside of the nut 21, and simultaneously aligns the locking pin 14 with the inlet / outlet 27 at the top of the locking sleeve 24. The operator slowly inserts the mounting base 12 into the locking sleeve 24 until the temperature sensor probe 17 extends to a suitable position inside the boiler. By rotating the mounting base 12, the locking pin 14 is moved into the locking groove 28. The locking block 26 blocks the locking pin 14, locking it in the locking groove 28 and preventing the mounting base 12 from coming out. After the temperature monitoring mechanism 1 is quickly installed, the temperature sensor probe 17 is used to monitor the wall temperature of the high-temperature tube panel inside the boiler in real time. The monitored temperature data is transmitted to the temperature monitoring instrument 11 for clear display, so that the staff can check the wall temperature of the high-temperature tube panel inside the boiler at any time. When disassembling the temperature monitoring mechanism 1, the operator pushes the limit ring 25 upward. The limit ring 25 drives the locking block 26 to move upward, releasing the blocking effect of the locking block 26 on the locking post 14. By operating the rotating mounting base 12 to rotate in the opposite direction, the locking post 14 is moved to the position of the inlet / outlet 27 and moved upward, so that the mounting base 12 can be quickly removed from the locking sleeve 24, completing the quick disassembly of the temperature monitoring mechanism 1.

[0040] Example 2:

[0041] Reference Appendix Figure 4 As shown, the top of the limiting ring 25 has an opening 29, which corresponds to the inlet and outlet 27.

[0042] As can be seen from the above, the opening 29 allows the locking pin 14 to be smoothly inserted into the inlet / outlet 27 without affecting the upward movement of the locking pin 14 from the inlet / outlet 27.

[0043] Reference Appendix Figure 5 As shown, the top of the locking sleeve 24 has a movable cavity 210, and an elastic element 211 is fixedly connected between the movable cavity 210 and the limiting ring 25.

[0044] As can be seen from the above, the elastic element 211 acts as a tension spring, providing tension to the limiting ring 25. In its natural state, the elastic element 211 pulls the limiting ring 25 downward, keeping the locking block 26 within the locking groove 28. This allows the locking block 26 to maintain its blocking effect on the pin 14. When the temperature monitoring mechanism 1 needs to be disassembled, simply push the limiting ring 25 upward to overcome the elastic force of the elastic element 211, separating the locking block 26 from the pin 14 for disassembly. After the limiting ring 25 is released, the elastic element 211 will automatically reset the limiting ring 25, returning the locking block 26 to the locked position, preparing it for the next installation and providing greater convenience for use.

[0045] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
