Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of coal-water slurry boilers, specifically a coal-water slurry boiler overheat monitoring device. Background Technology
[0002] With the increasing demands for efficient energy utilization and safe operation in industrial production, coal-water slurry, as an environmentally friendly coal-based fluid fuel, is being used more and more widely in the boiler field. However, during the operation of coal-water slurry boilers, local overheating is prone to occur due to factors such as fuel characteristics and changes in combustion conditions. This not only reduces boiler thermal efficiency and increases energy consumption, but may also lead to serious safety accidents such as damage to heating surfaces and tube rupture, threatening the stable operation of equipment and personnel safety. Therefore, to ensure the safe, efficient, and stable operation of coal-water slurry boilers, overheat monitoring devices have emerged to monitor boiler temperature changes in real time and promptly detect and warn of overheating risks.
[0003] Existing technology uses a traditional fixed installation method, which uses bolts to fix the monitoring device in a specific position. Once the monitoring point is determined, if the monitoring position needs to be adjusted later, the bolts need to be removed with tools. The process is cumbersome and time-consuming, making it difficult to effectively meet the monitoring needs for the safe and stable operation of boilers.
[0004] Therefore, a superheat monitoring device for coal-water slurry boilers is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a superheat monitoring device for coal-water slurry boilers.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The superheat monitoring device for a coal-water slurry boiler of this utility model includes a U-shaped plate; a slot is provided on the inner wall of the U-shaped plate; a slide rail is fixedly connected to the outer wall of the U-shaped plate; a U-shaped block is slidably connected to the outer wall of the slide rail; a rectangular groove is provided on the outer wall of the U-shaped block; a fixing block is fixedly connected to the inner wall of the U-shaped block; a sliding groove is provided inside the fixing block; one end of a spring is fixedly connected to the outer wall of the fixing block; a pressing block is fixedly connected to the other end of the spring; the outer wall of the pressing block is slidably connected to the inner wall of the rectangular groove; a locking block is fixedly connected to the outer wall of the pressing block; the outer wall of the locking block is slidably connected to the inner wall of the slot; a limiting post is fixedly connected to the outer wall of the pressing block; the outer wall of the limiting post is slidably connected to the inner wall of the sliding groove; the outer wall of the limiting post is slidably connected to the inner wall of the spring; and a monitoring component is provided on the outer wall of the U-shaped block.
[0007] Preferably, the monitoring component includes a second fixing block, the outer wall of which is fixedly connected to the outer wall of the U-shaped block, and a monitoring instrument is fixedly connected to the outer wall of the second fixing block, with a wire provided on the outer wall of the monitoring instrument.
[0008] Preferably, a connecting rod is fixedly connected to the lower surface of the U-shaped block, and a wire fixing block is fixedly connected to the lower surface of the connecting rod.
[0009] Preferably, a connecting rod two is fixedly connected to the lower surface of the U-shaped block, and one end of a spring two is fixedly connected to the outer wall of the connecting rod two.
[0010] Preferably, the other end of the second spring is fixedly connected to a second wire fixing block, and the inner wall of the second wire fixing block is connected to the outer wall of the wire.
[0011] Preferably, the inner wall of the fixing block is connected to the outer wall of the conductor.
[0012] The beneficial effects of this utility model are:
[0013] 1. This utility model provides a water-coal slurry boiler overheat monitoring device. When the card block slides out from the inner wall of the card slot, the U-shaped block is moved to make the inside of the U-shaped block slide on the outer wall of the slide rail. This causes the monitor to move along with the U-shaped block to adjust the monitoring position. It can flexibly adjust and capture key monitoring points according to the actual temperature distribution, flame shape changes and other dynamic conditions of the boiler during operation, and obtain accurate temperature data in real time.
[0014] 2. This utility model provides a water-coal slurry boiler overheat monitoring device. By allowing the U-shaped block to slide completely out of the outer wall of the slide rail, the monitoring instrument can be quickly disassembled. This allows for rapid disassembly and relocation during boiler shutdown for maintenance or adjustment of operating conditions, reducing downtime and improving maintenance efficiency.
[0015] 3. This utility model provides a water-coal slurry boiler overheat monitoring device. By using a spring in a contracted state to push the wire fixing block to reset, the wire is misaligned. During device installation, disassembly, or boiler operation vibration, the misaligned distribution of each section of the wire naturally buffers the stress, avoiding wire wear, breakage, or poor contact caused by straight pulling or excessive tension. This improves the reliability of the wire connection, reduces the risk of abnormal monitoring data or device failure caused by wire faults, and enhances the device's anti-interference ability and service life under complex operating conditions.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figures 1-3This utility model provides a water-coal slurry boiler overheat monitoring device, which includes a U-shaped plate 1; a groove 3 is formed on the inner wall of the U-shaped plate 1; a slide rail 2 is fixedly connected to the outer wall of the U-shaped plate 1; a U-shaped block 4 is slidably connected to the outer wall of the slide rail 2; a rectangular groove 7 is formed on the outer wall of the U-shaped block 4; a fixing block 5 is fixedly connected to the inner wall of the U-shaped block 4; a sliding groove 6 is formed inside the fixing block 5; one end of a spring 8 is fixedly connected to the outer wall of the fixing block 5; a pressing block 10 is fixedly connected to the other end of the spring 8; the outer wall of the pressing block 10 is slidably connected to the inner wall of the rectangular groove 7; a locking block 11 is fixedly connected to the outer wall of the pressing block 10; the outer wall of the locking block 11 is slidably connected to the inner wall of the groove 3; and a limiting post 9 is fixedly connected to the outer wall of the pressing block 10. The wall is slidably connected to the inner wall of the slide groove 6, and the outer wall of the limiting post 9 is slidably connected to the inner wall of the spring 8. The outer wall of the U-shaped block 4 is equipped with a monitoring component. The U-shaped plate 1 serves as a basic support structure, and the slot 3 on its inner wall cooperates with the locking block 11 to fix the position of the U-shaped block 4. The slide rail 2 on the outer wall provides a sliding track for the U-shaped block 4 to realize the position adjustment of the monitoring component. When the pressing block 10 is pressed, the locking block 11 slides out from the slot 3, releasing the fixed state, so that the U-shaped block 4 can move along the slide rail 2, thereby adjusting the position of the monitoring component. The spring 8 provides a reset elastic force to ensure that the locking block 11 can be stably locked into the slot 3 to fix the monitoring component. The limiting post 9 restricts the movement trajectory of the pressing block 10 to ensure the precise cooperation between the locking block 11 and the slot 3. The monitoring component is installed on the outer wall of the U-shaped block 4 for real-time monitoring of the boiler temperature.
[0027] Furthermore, such as Figure 1 , Figure 2 and Figure 3 As shown, the monitoring component includes a second fixing block 12, the outer wall of which is fixedly connected to the outer wall of the U-shaped block 4. A monitoring instrument 13 is fixedly connected to the outer wall of the second fixing block 12, and a wire 14 is provided on the outer wall of the monitoring instrument 13. In the monitoring component, the second fixing block 12 serves as a connecting carrier, fixing the monitoring instrument 13 to the outer wall of the U-shaped block 4, so that the monitoring instrument 13 can move and adjust its position along the slide rail 2 with the U-shaped block 4. The monitoring instrument 13 is the core monitoring component, used to collect temperature data in real time during boiler operation, providing a basis for overheat risk warning. The wire 14 is responsible for transmitting the temperature signal acquired by the monitoring instrument 13, realizing real-time data output and feedback.
[0028] Furthermore, such as Figure 2 and Figure 4As shown, a connecting rod 15 is fixedly connected to the lower surface of the U-shaped block 4, and a wire fixing block 16 is fixedly connected to the lower surface of the connecting rod 15. The connecting rod 15 on the lower surface of the U-shaped block 4 is used to connect the wire fixing block 16, extending the wire fixing block 16 to the vicinity of the wire 14 below the monitor 13. The wire fixing block 16 forms a limiting fixation on the wire 14 through its inner wall. In conjunction with the movement of the U-shaped block 4, it adjusts the fixed position of the wire 14 below the monitoring component, disperses the force on the wire 14 when the device moves or the boiler vibrates, and avoids the wire 14 from affecting the position adjustment and signal transmission stability of the monitor 13 due to excessive slack or tightness.
[0029] Furthermore, such as Figure 2 and Figure 4 As shown, a connecting rod 17 is fixedly connected to the lower surface of the U-shaped block 4. One end of a spring 18 is fixedly connected to the outer wall of the connecting rod 17. The connecting rod 17 on the lower surface of the U-shaped block 4 is used to fix one end of the spring 18, so that the spring 18 can extend vertically to the vicinity of the conductor 14. The spring 18 provides dynamic support force for the wire fixing block 19 through its elastic deformation characteristics. When the wire fixing block 19 is pressed, it contracts under force and rebounds after release, causing the wire fixing block 19 to move. This causes the conductor 14 to form a staggered layout, buffering the tensile force on the conductor 14 during device installation, disassembly, or boiler vibration, and preventing the conductor 14 from wearing or breaking due to linear force. At the same time, the elastic buffering characteristics of the spring 18 enhance the stability of the conductor 14 connection.
[0030] Furthermore, such as Figure 2 and Figure 4 As shown, the other end of the second spring 18 is fixedly connected to the second wire fixing block 19. The inner wall of the second wire fixing block 19 is connected to the outer wall of the wire 14. The other end of the second spring 18 is connected to the wire 14 through the second wire fixing block 19. The inner wall of the second wire fixing block 19 clamps and fixes the wire 14. When the second wire fixing block 19 is pressed, the second spring 18 is compressed by force, which drives the second wire fixing block 19 to move down, and the wire 14 is pulled down and bends.
[0031] Furthermore, such as Figure 2 and Figure 4 As shown, the inner wall of the first fixing block 16 is connected to the outer wall of the conductor 14. The inner wall of the first fixing block 16 is connected to the outer wall of the conductor 14. By limiting the conductor 14, a fixed fulcrum is formed, which constrains the conductor 14 at a specific position below the monitor 13. With the dynamic adjustment of the second fixing block 19, the conductor 14 forms a segmented fixed layout between the two.
[0032] Working principle: During use, the monitoring instrument 13 is activated to monitor the overheating of the coal-water slurry boiler. When it is necessary to adjust the monitoring position of the monitoring instrument 13, simply press the actuating block 10 to make it slide in the inner wall of the rectangular groove 7 opened on the outer wall of the U-shaped block 4. As the actuating block 10 slides in the inner wall of the rectangular groove 7, it will move inward and drive the locking block 11 to move inward and slide out from the inner wall of the current position of the locking groove 3. During this process, it will cause the limiting post 9 to move inward and slide in the inner wall of the sliding groove 6 opened inside the fixed block 5. At the same time, it will cause the spring 8 to be compressed and slide in the outer wall of the limiting post 9. When the locking block When the U11 slides out from the inner wall of the slot 3, the U-shaped block 4 is moved to slide inside the slide rail 2, thereby moving the monitor 13 to adjust its monitoring position. It can flexibly adjust and capture key monitoring points according to the actual temperature distribution and flame shape changes during boiler operation, and obtain accurate temperature data in real time. At the same time, the U-shaped block 4 can slide completely out from the outer wall of the slide rail 2, achieving the effect of quick disassembly of the monitor 13. It can be disassembled and redeployed in a short time when the boiler is shut down for maintenance or when the operating conditions are adjusted, reducing downtime and improving maintenance efficiency.
[0033] During use, pressing the second fixing block 19 causes it to compress the second spring 18. Then, the wire 14 is passed through the inner walls of the first fixing block 16 and the second fixing block 19. After the wire 14 passes through, the second fixing block 19 is no longer pressed, causing the spring 18, which is in a compressed state, to spring back and reset, pushing the second fixing block 19 to reset. This causes the wire 14 to become misaligned, so that during the installation, disassembly, or vibration of the boiler during operation, the different sections of the wire 14 are naturally buffered by the misaligned distribution, avoiding wear, breakage, or poor contact of the wire 14 due to straight pulling or excessive tension. This improves the reliability of the wire 14 connection, reduces the risk of abnormal monitoring data or device failure caused by wire 14 failure, and enhances the device's anti-interference ability and service life under complex working conditions.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
