Description

Technical Field

[0001] The present disclosure relates to the technical field of boilers, and in particular, to a monitoring device for a boiler. Background Art

[0002] A boiler is an energy conversion device that outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy by inputting chemical energy or electrical energy in the fuel. The outer wall of the boiler, as a key component of the boiler structure, not only bears the overall structural stability of the boiler, but also directly contacts the flame or high-temperature flue gas in the furnace. As the main heating surface, it continuously absorbs huge heat from the combustion process and efficiently transfers it to the water or steam inside, thereby driving the entire thermal energy conversion process. The heating surface of the boiler is a key part of the boiler for heat exchange. Real-time monitoring of the boiler heating surface is crucial, which can help to promptly discover and solve problems such as ash accumulation and coking. These problems will seriously affect the heat exchange effect of the heating surface, resulting in reduced boiler efficiency, increased energy consumption, and even damage to the boiler equipment.

DETAILED DESCRIPTION

[0036] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0037] In the present disclosure, unless otherwise stated, directional words such as "upper" and "lower" are defined for the arrangement direction of the monitoring device when it is actually used, and directional words such as "inner" and "outer" are defined for the outline of the corresponding component. The terms "first" and "second" are used to distinguish different components and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements.

[0038] According to one embodiment of the present disclosure, Figures 1 to 6 As shown, a monitoring device for a boiler is provided, including a base 1, two sliders 2, an arc plate 3, a power assembly 4 and a plurality of first temperature detection elements 51. The base 1 can be used to place the boiler 7. The sliders 2 can be arranged on the base 1 and are arranged at intervals on both sides of the boiler 7. The ends of the arc plate 3 can be fixedly connected to the two sliders 2 respectively, and the arc plate 3 is arranged circumferentially on the outside of the boiler 7. The power assembly 4 can be arranged on the base 1 and connected to at least one slider 2, and is used to drive the slider 2 to reciprocate along the length direction of the boiler 7. A plurality of first temperature detection elements 51 are arranged at intervals on the arc plate 3 and are arranged circumferentially along the outside of the boiler 7, and are used to obtain the temperature information of the boiler 7. The temperature information here can be a specific temperature value, or it can be image information formed by infrared imaging according to the temperature value, which is not limited in the present disclosure.

[0039] Through the above technical scheme, the arc plate 3 is arranged circumferentially along the outer surface of the boiler 7, and a plurality of first temperature detection elements 51 are provided on the arc plate 3. At the same time, the arc plate 3 can be moved along the length direction of the boiler 7 driven by the power assembly 4 through the connected slider 2. The device has a simple structure and is easy to operate. It can effectively monitor the temperature of the outer surface of the boiler 7, timely discover and solve problems such as dust accumulation and coking, ensure the heat exchange effect of the boiler heating surface, ensure the safety of the boiler 7, improve the operating efficiency and energy utilization efficiency of the boiler 7, and extend the service life of the equipment.

[0040] It should be noted that the power assembly 4 can be one and connected to only one slider 2, or the number of power assemblies 4 can be two and connected to two sliders 2 respectively, which can make the slider 2 and the arc plate 3 more stable when moving, and prevent the arc plate 3 from shaking during the movement, resulting in the first temperature detection element 51 and the second temperature detection element 52 described below from being inaccurately detected. Two chutes 11 extending in the same direction as the boiler 7 can also be provided on the base 1, and the two chutes 11 are respectively located on both sides of the boiler 7, and the two sliders 2 are movably arranged in the two chutes 11. In this way, when the power assembly 4 drives the two sliders 2 to move, the two sliders 2 move along the two chutes 11 respectively, which can also make the slider 2 and the arc plate 3 move more stably, and prevent the arc plate 3 from shaking during the movement, resulting in the first temperature detection element 51 and the second temperature detection element 52 described below from being inaccurately detected, thereby improving the accuracy of temperature detection.

[0041] Furthermore, if Figure 5 and Figure 6 As shown, the first temperature detection element 51 is connected to the plug block 511, the plug block 511 is provided with a first groove 512, the first groove 512 is provided with an elastic member 6, one end of the elastic member 6 is connected to the bottom wall of the first groove 512, the side of the elastic member 6 away from the bottom wall of the first groove 512 is connected to a fixed block 61, and the fixed block 61 can be moved relative to the plug block 511, and the arc plate 3 is provided with a plurality of second grooves 30 that cooperate with the plug block 511 at intervals, and the side wall of the second groove 30 is provided with a third groove 31 that cooperates with the fixed block 61. The elastic member 6 can be a spring or an elastic rubber, which is not limited in the present disclosure. When the first temperature detection element 51 needs to be installed on the arc plate 3, it is only necessary to align the plug block 511 with the second groove 30, press the fixing block 61, compress the elastic member 6 so that the fixing block 61 is flush with the plug block 511, and then the plug block 511 can be inserted into the second groove 30. When the fixing block 61 is located at the position of the third groove 31, the elastic member 6 releases the elastic force to insert the fixing block 61 into the third groove 31, thereby realizing the rapid installation of the first temperature detection element 51 and the arc plate 3. When the first temperature detection element 51 needs to be removed, since the elastic member 6 has elastic force and is connected to the bottom wall of the first groove 512, it is only necessary to pull the first temperature detection element 51. Under the action of the elastic force, the elastic member 6 can pull the fixing block 61 away from the third groove 31, thereby completing the removal of the first temperature detection element 51. It should be noted that the number of second grooves 30 can be greater than the number of first temperature detection elements 51, that is, the first temperature detection elements 51 can be arranged one-to-one with the second grooves 30, and the interval between adjacent first temperature detection elements 51 can also be increased, that is, adjacent first temperature detection elements 51 can be arranged with one or two second grooves 30 apart, and the present disclosure does not limit this.

[0042] Furthermore, if Figure 5 and Figure 6 As shown, the fixing block 61 may be a hemispherical body, and the third groove 31 may be a curved groove that matches the fixing block 61. The structure of the hemispherical body and the curved groove matching can facilitate the insertion and removal of the fixing block 61 from the third groove 31, saving installation time. The fixing block 61 may be a cone, and the third groove 31 may be a matching conical groove structure, which is not limited in the present disclosure.

[0043] According to one embodiment of the present disclosure, Figures 1 to 4 As shown, the monitoring device may further include two second temperature detection elements 52, which are arranged one by one on the side of the two sliders 2 close to the boiler 7. Since the sliders 2 are located below the arc plate 3, the second temperature detection elements 52 are also located near the bottom of the boiler 7. The second temperature detection elements 52 detect the bottom temperature of the boiler 7, and cooperate with the first temperature detection element 51 to detect the temperature of the outer surface of the boiler 7 (i.e., the heating surface of the boiler), so that the temperature of different positions of the boiler 7 can be more comprehensively monitored to improve the safety of the operation of the boiler 7.

[0044] Furthermore, the first temperature detection element 51 and the second temperature detection element 52 can both be thermal imagers, which can display different colors on the screen according to the temperature value feedback of the corresponding position detected, so as to more intuitively display the temperature conditions of different positions of the boiler 7, and facilitate the monitoring personnel to make judgments based on the temperature images fed back by the thermal imager. When there are abnormal temperature points in the boiler 7, it can also be more intuitively found to facilitate the investigation of the abnormal position of the boiler 7. The thermal imager can be connected to the controller. As the core component of the real-time monitoring structure of the boiler heating surface, the controller is responsible for receiving and processing the data signal from the thermal imager. It can analyze the collected temperature information in real time according to the preset algorithm to determine whether the state of the heating surface and the bottom of the boiler 7 is normal. Once an abnormality is found, such as local overheating or uneven temperature distribution, the controller will immediately send out an alarm signal, and can adjust the position and angle of the monitoring equipment by controlling the drive motor 41 and the regulating motor to ensure continuous monitoring of the problem area. In addition, the controller can also record historical data to provide reference for subsequent troubleshooting and system optimization. Through this intelligent control method, the safety and efficiency of boiler operation are ensured. The first temperature detection element 51 and the second temperature detection element 52 may also be thermocouples or temperature sensors, which is not limited in the present disclosure.

[0045] According to one embodiment of the present disclosure, Figures 1 to 4As shown, the side of the slider 2 close to the boiler 7 can also be provided with an adjustment part, which is connected to the second temperature detection element 52 and is used to adjust the angle of the second temperature detection element 52. Since the bottom of the boiler 7 is a rectangular parallelepiped and the upper part is a cylinder, the first temperature detection element 51 is distributed in the cylindrical part, and the second temperature detection element 52 is distributed in the rectangular parallelepiped part. The width of the rectangular parallelepiped is smaller than the diameter of the cylinder. Therefore, the surface of the cylinder near the junction of the rectangular parallelepiped and the cylinder faces downward. The temperature at this position is located on the arc plate 3 on the side, and the first temperature detection element 51 is prone to insensitive detection. Therefore, the second temperature detection element 52 is connected to the slider 2 through the adjustment part. By adjusting the angle of the second temperature detection element 52 through the adjustment part, the detection part of the second temperature detection element 52 can correspond to the position of the dead angle of the boiler 7, so as to monitor the temperature of the boiler 7 more comprehensively to ensure the safety and efficiency of the boiler operation.

[0046] Furthermore, if Figure 3 and Figure 4 As shown, the adjustment part may include a fixed seat 21, an adjustment rod 22 and an adjustment motor. Among them, the fixed seat 21 can be set on the slider 2. The adjustment rod 22 can be rotatably installed on the fixed seat 21, and the second temperature detection element 52 is connected to the adjustment rod 22. The output end of the adjustment motor is connected to the adjustment rod 22, which is used to drive the adjustment rod 22 to rotate. The adjustment rod 22 is driven to rotate by the adjustment motor to drive the second temperature detection element 52 to rotate, so as to adjust the angle of the second temperature detection element 52, so as to monitor the temperature of the boiler 7 more comprehensively to ensure the safety and efficiency of the boiler operation.

[0047] According to one embodiment of the present disclosure, Figures 1 to 3As shown, the power assembly 4 may include a driving motor 41, a screw rod 42 and a magnet 43. The screw rod 42 is connected to the output end of the driving motor 41, and the screw rod 42 extends in the same direction as the boiler 7. The magnet 43 is movably arranged on the screw rod 42, and the magnet 43 is magnetically connected to the slider 2. The driving motor 41 drives the screw rod 42 to rotate, and the rotation of the screw rod 42 drives the magnet 43 to produce displacement, and the magnet 43 drives the slider 2 magnetically connected thereto to move, thereby driving the arc plate 3 connected to the slider 2 to move, so that the first temperature detection element 51 and the second temperature detection element 52 move along the extension direction of the boiler 7, so as to detect the temperature at different positions of the outer surface of the boiler 7. Here, a placement groove may also be provided on the side wall of the base 1, and the driving motor 41 and the screw rod 42 may be located in the placement groove, and the magnet 43 may also be grooved to cooperate with the upper and lower surfaces of the placement groove, so that the moving trajectory of the magnet 43 can be limited to prevent the magnet 43 from producing other displacements not along the extension direction of the boiler 7, and the present disclosure does not limit this. The power component 4 can also be a mechanism in which a cylinder or a hydraulic cylinder drives a magnetic block. The cylinder body of the cylinder or the hydraulic cylinder is fixed on the base 1, and the piston rod is arranged in the cylinder body for reciprocating motion. The magnetic block is fixed at one end of the piston rod away from the cylinder body. In this way, the reciprocating motion of the piston rod can drive the magnetic block to reciprocate. The present disclosure does not limit this.

[0048] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0050] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
