Description

Technical Field

[0001] This utility model relates to the technical field of fire observation devices, and in particular to a fire observation device. Background Technology

[0002] A furnace observation device is used to observe the combustion situation inside a boiler furnace. It is typically installed on the boiler wall and extends into the furnace through an observation hole, allowing operators to observe the flame status from the outside. The device usually includes an observation channel extending into the boiler furnace through the observation hole in the boiler wall, and an observation hole door with a transparent industrial lens installed at the outer end of the observation channel, located outside the furnace.

[0003] In related technologies, most furnace observation devices rely on manual opening and closing of the observation hole. However, this method poses certain safety hazards. Under unstable furnace negative pressure, manually opening the observation hole may cause flames to erupt instantly, threatening the observer's safety. Furthermore, manual operation can be affected by factors such as the operator's experience and environmental conditions, limiting the accuracy and timeliness of the observation results.

[0005] To achieve the above objectives, this utility model proposes a fire observation device applied to the furnace wall. The fire observation device includes an observation port and an observation mirror. The observation port is located in the furnace. The fire observation device further includes:

[0006] The housing has an internal fire-observation channel, one end of which is connected to the fire-observation port, and the other end of which is equipped with the fire-observation mirror.

[0007] A fire baffle, which is movably disposed within the fire observation passage;

[0008] A first driving component is disposed inside the inner wall of the housing. The first driving component is connected to the fire baffle plate and can drive the fire baffle plate to open or close the fire viewing channel.

[0009] In one embodiment, the fire-observation device further includes a magnetic structure, which includes a first magnetic member and a second magnetic member that are magnetically connected.

[0010] In one embodiment, the fire baffle is rotatably disposed within the fire observation channel, the first driving member is located at one end of the fixed end of the fire baffle, and the housing has a first receiving portion, in which the first driving member is received.

[0011] In one embodiment, the fire observation device further includes an air blowing pipe, the inner cavity of which connects the fire observation channel to the outside. The air blowing pipe is located at the end of the fire observation channel away from the movable end of the fire baffle. The air blowing pipe has a nozzle, the opening of which is oriented toward the center of the fire observation mirror. The air blowing pipe is used to cool the fire observation mirror when the fire baffle is opened.

[0012] In one embodiment, a maintenance hole plate is provided at one end of the housing away from the fixed end of the fire baffle, and the maintenance hole plate is rotatably connected to the inner wall of the housing.

[0026] This utility model proposes a fire observation device 100.

[0027] Please see Figures 1 to 2 In one embodiment of this utility model, the fire observation device 100 is applied to the furnace wall of the furnace chamber. The fire observation device includes a fire observation port 5 and a fire observation mirror 2. The fire observation port 5 is located in the furnace chamber. The fire observation device also includes a housing 1, a fire baffle 3, and a first driving member 4. A fire observation channel 11 is opened inside the housing 1. One end of the fire observation channel 11 is open and connected to the fire observation port 5. The other end of the fire observation channel 11 is equipped with a fire observation mirror 2. The fire baffle 3 is movably located inside the fire observation channel 11. The first driving member 4 is located inside the inner wall of the housing 1. The first driving member 4 is connected to the fire baffle 3 and can drive the fire baffle 3 to open or close the fire observation channel 11.

[0028] In this embodiment, the fire observation device can be applied to equipment such as industrial boilers and smelting furnaces that require observation of the combustion inside the furnace. An industrial boiler is used as an example for illustration. It should be noted that the housing 1 provides a position for installation and fixation, ensuring the structural stability and integrity of the entire device, allowing it to be firmly installed on the furnace wall. The housing is made of alloy steel, stainless steel, etc. An observation channel 11 is formed inside the housing 1. This observation channel 11 has two interconnected openings, one of which connects to the observation port 5, and the other opening is equipped with an observation mirror 2. A fire baffle 3 is also provided inside the observation channel 11. The fire baffle 3 opens and closes the observation channel 11 under the action of a first driving member 4. The type of the first driving member 4 includes, but is not limited to, cylinders, drive motors, etc., with a drive motor being preferred here. It is understood that the fire baffle 3 performs the opening and closing operation of the observation channel 11. The fire baffle 3 can be opened and closed not only by moving up and down but also by rotating; this is not limited here. In one embodiment, the inner cavity of the housing 1 is provided with a guide rail, which is positioned perpendicularly to the observation channel 11, allowing the fire baffle 3 to move up and down along the guide rail, thereby enabling the opening and closing of the observation channel 11. Specifically, the fire baffle 3 exists in three states under the drive of the first driving member 4. The first state is the closed state, in which the fire baffle 3 completely blocks the extension direction of the observation channel 11, making it impossible to observe the flame inside the furnace. The second state is the half-open state, in which the fire baffle 3 is set at an angle to the extension direction of the observation channel 11, including but not limited to 30 degrees, 45 degrees, and 60 degrees. The third state is the fully open state, in which the fire baffle 3 is set parallel to the extension direction of the observation channel 11.

[0029] The technical solution of this utility model, through the configuration of a housing 1, a fire observation channel 11, a fire observation mirror 2, a movable fire baffle 3, and a first driving component 4, allows the fire observation channel 11 to be opened when observation of the furnace flame is needed and closed when observation is not required. This effectively prevents high-temperature flue gas or flames from being ejected and causing injury when the negative pressure in the furnace is unstable, ensuring the safety of operators. Simultaneously, the first driving component 4 can drive the fire baffle 3 to open or close the fire observation channel 11 as needed. The electric control operation is convenient and can meet the observation needs under different working conditions, preventing personnel injury.

[0030] In one embodiment of the present invention, the fire observation device further includes a magnetic structure 6, which includes a first magnetic member 61 and a second magnetic member 62 that are magnetically connected. The first magnetic member 61 is disposed at the movable end of the fire baffle plate 3, and the second magnetic member 62 is disposed on the inner wall of the housing 1.

[0031] In this embodiment, to enhance the closing stability of the fire baffle 3, a magnetic attractor is provided at the movable end of the fire baffle 3 and on the inner wall of the housing 1, respectively, to ensure the sealing of the fire viewing channel 11 and prevent leakage of flames and high-temperature smoke. It is understood that the first magnetic attractor 61 and the second magnetic attractor 62 need to be accurately aligned to achieve the best magnetic attraction effect. The type of magnetic structure 6 includes, but is not limited to, rare-earth permanent magnets, magnetic metals, and other high-temperature resistant magnetic materials, and is not limited here. It is understood that the number of the first magnetic attractor 61 and the second magnetic attractor 62 is not limited; it can be one, two, etc. The above arrangement simplifies operation and saves power.

[0032] In one embodiment of the present invention, the fire baffle 3 is rotatably disposed in the fire observation channel 11, the first driving member 4 is located at one end of the fixed end of the fire baffle 3, and the housing 1 is provided with a first receiving part, in which the first driving member 4 is received.

[0033] In this embodiment, to achieve a compact structure and optimized space, the fire baffle 3 is rotatably disposed within the fire observation channel 11. The fire baffle 3 is rotated by a first driving member 4 to open or close the fire observation channel 11. A receiving portion is provided within the housing 1, and the first driving member 4 is housed within this receiving portion. In one embodiment, the receiving portion can be a groove or a specific chamber. The first driving member is typically fixed to the receiving portion by bolts, clips, or other connection methods. It is understood that the fire baffle 3 can be installed within the fire observation channel 11 via a rotating component such as a shaft or hinge, allowing it to rotate around a fixed end. The first driving member 4 (such as a motor or cylinder) is installed at one end of the fixed end of the fire baffle 3 and is connected to the fire baffle 3 in a transmission manner. When the first driving member 4 operates, the force or torque it generates is transmitted to the shaft of the fire baffle 3, causing the fire baffle 3 to rotate around its fixed end, thereby opening or closing the fire observation channel 11.

[0034] In one embodiment of the present invention, the fire observation device further includes an air blowing pipe 13. The inner cavity of the air blowing pipe 13 is connected to the fire observation channel 11 and the outside. The air blowing pipe 13 is located at one end of the fire observation channel 11 away from the movable end of the fire baffle 3. The air blowing pipe 13 has a nozzle 131. The opening direction of the nozzle 131 is set towards the center of the fire observation mirror 2. The air blowing pipe 13 is used to cool the fire observation mirror 2 when the fire baffle 3 is opened.

[0035] In this embodiment, when the fire baffle 3 is opened, the observation mirror 2 is easily damaged or blurred due to thermal shock or smoke adhesion in a high-temperature environment. The air blowing pipe 13 connects to the outside environment (meaning the air source equipment). The outside gas connected to the air source equipment is used for cooling, thereby forming a protective film to prevent the high-temperature flames and smoke in the furnace from directly contacting the observation mirror 2, reducing thermal shock and high-temperature erosion, and extending the service life of the observation mirror 2. Combined with... Figure 1 and Figure 2 The air blowing pipe 13 can be installed on the inspection hole plate 12 or inside the inner wall of the housing 1, as long as it does not interfere with the movement of the fire baffle 3. Preferably, this application installs the air blowing pipe 13 on the inspection hole plate 12, making it easier for operators to access the air blowing pipe during internal equipment inspection or maintenance. This facilitates cleaning, inspection, repair, or replacement without the need to disassemble other components to access the air blowing pipe, saving time and labor costs. It is understood that the installation method of the air blowing pipe 13 on the inspection hole plate 12 includes, but is not limited to, using clamps to tightly press the air blowing pipe 13 and the inspection hole plate 12 together; or using flanges and bolts / nuts to tightly connect the air blowing pipe and the inspection hole plate, forming a firm connection through the pre-tightening force of the bolts; or connecting the air blowing pipe 13 and the inspection hole plate 12 together by welding. Figure 2 It should be noted that the opening of nozzle 131 is oriented towards the center of the observation mirror 2, that is... Figure 2 The direction indicated by the arrow next to the dotted line is designed to better cool the observation mirror 2 with gas. Gas flows out from nozzle 131 of the gas blowing pipe 13. When it contacts the central axis of the observation mirror 2, the gas flows up and down along the mirror 2, forming an air wall on its surface. This isolates the high-temperature flames and flue gas in the furnace from direct contact with the observation mirror 2, reducing thermal shock and high-temperature erosion, and extending the service life of the observation mirror 2. This design improves the clarity of fire observation and the accuracy of operators' monitoring of the furnace interior.

[0036] In one embodiment of this utility model, a maintenance hole plate 12 is provided at one end of the housing 1 away from the fixed end of the fire baffle plate 3, and the maintenance hole plate 12 is rotatably connected to the inner wall of the housing 1.

[0037] In this embodiment, for ease of maintenance and repair, the inspection hole plate 12 is connected to the inner wall of the housing 1 via a hinge and a rotating shaft, allowing it to rotate around a fixed axis. This connection method allows the inspection hole plate 12 to be opened when maintenance is needed, facilitating access for personnel to inspect the fire observation device; when maintenance is not required, the inspection hole plate 12 is closed, restoring the sealing and integrity of the fire observation device. It is understood that the connection between the inspection hole plate 12 and the inner wall of the housing 1 can be, but is not limited to, via a hinge or a rotating mechanism that allows for disassembly.

[0038] In one embodiment of this utility model, the fire observation device further includes a pressure relief valve 14, which is installed through the inspection hole plate 12 and connects the fire observation channel 11 to the outside.

[0039] In this embodiment, to protect the fire observation device, a pressure relief valve 14 is provided to promptly release pressure within the fire observation channel 11. The pressure relief valve 14 passes through the inspection orifice plate 12, allowing operators to easily perform maintenance, repair, or replacement of the valve through the orifice plate 12. It should be noted that "outside" here refers to the atmospheric environment. It is understood that the pressure relief valve 14 can relieve pressure in various ways, including but not limited to manual or electric methods, and is not limited here. The type of pressure relief valve 14 includes, but is not limited to, spring-loaded pressure relief valves 14, lever-type pressure relief valves 14, and electric pressure relief valves 14, etc., and is not limited here; it can be set according to specific needs.

[0040] In one embodiment of this utility model, the fire observation device further includes a pressure sensor and a controller. The pressure sensor is communicatively connected to the controller, and the controller is communicatively connected to the first drive component 4 and the pressure relief valve 14. The pressure sensor is located on the inner wall of the housing 1 and is positioned near the fire observation port 5. A shielding cover is provided on the outer side of the pressure sensor.

[0041] In this embodiment, to improve safety, a pressure sensor is provided. This sensor monitors the internal pressure of the observation device in real time. When the pressure inside the furnace exceeds a safety threshold (i.e., when the pressure inside the furnace is positive), the controller reacts quickly, controlling the first drive component 4 to open the observation channel via the fire baffle 3. The air pressure inside the observation channel is then released through the pressure relief valve 14, effectively preventing explosions or equipment damage caused by excessive pressure and protecting the safety of operators and equipment. Simultaneously, by automatically monitoring and adjusting the pressure, the observation device can maintain stable internal pressure under different operating conditions, ensuring normal operation. This automated pressure control mechanism reduces the uncertainty and error of manual intervention, improving the reliability and stability of the device. The pressure sensor used here includes, but is not limited to, strain gauge pressure sensors, piezoelectric pressure sensors, and capacitive pressure sensors.

[0042] In one embodiment of this utility model, the fire observation device further includes two fasteners. The outer walls of opposite sides of the housing 1 are respectively provided with a through hole 7, and each fastener passes through a through hole 7 and is fixedly connected to the furnace.

[0043] In this embodiment, in order to enhance the installation stability of the device, the fire observation device is fixed to the furnace by two fasteners. The fasteners pass through the through holes 7 on opposite sides of the outer wall of the housing 1 and are connected to the furnace. This design can provide a uniform and symmetrical fixing force, making the fire observation device more stable on the furnace and less likely to loosen or shift due to furnace vibration, high temperature or other external forces, thus ensuring the reliability of the device during operation.

[0044] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
