Description

Technical Field

[0001] This application relates to the technical field of burner auxiliary equipment, and in particular to a burner flame detection connector and sight glass connector assembly structure. Background Technology

[0002] During the operation of the burner, the combustion status of the flame needs to be monitored in real time through a flame detection device to ensure the safe and stable operation of the burner. At the same time, a sight glass device is also needed to allow staff to directly observe the combustion situation inside the burner.

[0003] In the prior art, the flame detection device and the sight glass device are connected to the burner through the flame detection pipe and the sight glass pipe on the burner, respectively; however, the flame detection pipe and the sight glass pipe occupy a large space, which is not conducive to the compact layout of the overall structure of the burner, and the convenience of use is greatly reduced, especially in scenarios with limited installation space. Utility Model Content

[0004] This application proposes a burner flame detection connector and sight glass connector assembly structure that integrates the flame detection connector and sight glass connector together, thereby reducing the space occupied by the flame detection connector and sight glass connector.

[0005] This application provides a burner flame detection connector and sight glass connector assembly structure, which adopts the following technical solution: A burner flame detection connector and sight glass connector assembly structure includes: Install the connecting pipe to connect to the inside of the burner; The fire detection pipe is connected to the installation pipe; The sight glass connector is connected to the installation connector. Flame detector mounting connector assembly, which is installed on the flame detector connector for subsequent installation of the flame detector device; The sight glass assembly, installed on the sight glass connector, is used to observe the combustion process inside the burner.

[0006] By adopting the above technical solution, the installation pipe connected to the burner is used as the basic carrier to integrate the flame detection pipe and the sight glass pipe, and to match the corresponding functional components. The traditional separate flame detection pipe and sight glass pipe are integrated into a single structure. This retains the dual core functions of flame monitoring and internal observation, and reduces the space occupied by the two when they are set up separately through centralized layout, making it suitable for scenarios with limited installation space.

[0007] Preferably, the flame detection connector and the sight glass connector are integrally formed, the flame detection connector and the installation connector are coaxially arranged, and the flame detection connector is located at the end of the installation connector away from the burner; the axis of the sight glass connector is perpendicular to the flame detection connector and is connected to the flame detection connector, and the sight glass connector is located on the side wall of the flame detection connector; a reflector is provided at the end of the installation connector away from the burner, the reflector is located at the connection position of the flame detection connector and the sight glass connector, and the reflector is tilted to reflect the light in the burner so that it passes through the sight glass connector; the reflector has a clearance hole to leave detection space after the flame detector is installed.

[0008] By adopting the above technical solutions, the integrated design of the flame detection connector and the sight glass connector enhances the integrity and connection stability of the connector structure and reduces the risk of leakage. The coaxial arrangement of the flame detection connector and the installation connector ensures that the flame detector can be directly facing the area of ​​the combustion flame during subsequent installation, ensuring that the detection effect is not affected. The tilted reflector can reflect the light inside the burner and pass through the sight glass connector to be captured by the sight glass assembly, realizing the function of observing the inside of the burner. The avoidance hole on the reflector can prevent the reflector from blocking the detection path of the flame detection device, realizing the compatibility of monitoring and observation functions.

[0009] Preferably, the flame detector mounting connector assembly includes a flame detector mounting connector and a sealing ring for mounting the flame detector. The flame detector mounting connector is fixed to the end of the flame detector connector away from the mounting connector by screwing on a thread. The sealing ring is located at the contact surface between the flame detector mounting connector and the mounting connector.

[0010] By adopting the above technical solutions, the threaded tightening method makes the installation and disassembly of the flame detector joint more convenient, facilitating the subsequent installation, maintenance and replacement of the flame detector device; the sealing ring enhances the sealing performance of the contact surface between the flame detector joint and the installation pipe, effectively preventing gas leakage inside the burner and ensuring the safe operation of the equipment.

[0011] Preferably, the sight glass assembly includes a pressure cap, a sight glass, and a sealing gasket. The pressure cap is sleeved on the sight glass guide tube, the sight glass is clamped between the pressure cap and the sight glass guide tube, and the sealing gasket is disposed on the contact surface between the sight glass and the sight glass guide tube.

[0012] By adopting the above technical solution, the clamping structure of the gland and the sight glass connector can firmly fix the sight glass and prevent it from loosening during equipment operation; the sealing gasket fills the gap between the sight glass and the sight glass connector, improves the sealing performance, prevents gas leakage, and ensures the safe operation of the equipment.

[0013] Preferably, the flame detector mounting connector is provided with a reflector fixing sleeve, which is provided through at both ends. The end face of the reflector fixing sleeve near the sight glass connector is inclined and forms an acute angle with the end face of the sight glass connector. An annular protrusion is provided on the edge of the end face of the reflector fixing sleeve near the sight glass connector, and the reflector contacts the annular protrusion and is blocked and limited by the annular protrusion.

[0014] By adopting the above technical solution, when installing the reflector, the reflector is inserted axially from the end of the reflector fixing sleeve away from the burner; the reflector is slowly pushed into the reflector fixing sleeve until its edge contacts the annular protrusion and is blocked, and cannot be pushed further; at this time, the reflector and the end face of the sight glass connector form an acute angle, ensuring that the light reflected by the reflector passes through the sight glass connector and is captured by the sight glass assembly; the annular protrusion enables the rapid installation and replacement of the reflector.

[0015] Preferably, it also includes a switching valve, which is installed at the connection between the installation pipe and the flame detection pipe. The switching valve connects the installation pipe and the flame detection pipe in series and is used to isolate toxic and harmful flue gas in the burner during maintenance.

[0016] By adopting the above technical solution, the switch valve is set at the connection between the installation pipe and the flame detection pipe. Utilizing the valve's on / off function, the valve is closed when the component needs maintenance, directly isolating the passage between the installation pipe and the inside of the burner. This prevents toxic and harmful fumes from entering the pipe and maintenance area, avoiding contact with harmful gases for maintenance personnel and providing safety assurance for maintenance operations.

[0017] Preferably, the side wall of the mounting pipe is connected to a cooling air duct, and the end of the cooling air duct away from the mounting pipe is connected to a compressed air source. The cooling air duct is used to introduce compressed air into the mounting pipe to absorb heat.

[0018] By adopting the above technical solution, compressed air is introduced into the installation pipe through the cooling air pipe. The compressed air absorbs the heat of the entire component, eliminating the need to supply cooling air to the phase detection component and the sight glass component separately, thus saving cooling air consumption.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. By using the installation pipe connected to the burner as the basic carrier, the flame detection pipe and sight glass pipe are integrated and equipped with corresponding functional components, the traditional separate flame detection pipe and sight glass pipe are integrated into a single structure; it retains the dual core functions of flame monitoring and internal observation, and reduces the space occupied by the two when set up separately through centralized layout, making it suitable for scenarios with limited installation space. 2. The integrated design of the flame detection connector and sight glass connector enhances the overall integrity and connection stability of the connector structure, reducing the risk of leakage. The coaxial arrangement of the flame detection connector and the installation connector ensures that the flame detector can be directly facing the area of ​​the combustion flame during subsequent installation, ensuring that the detection effect is not affected. The tilted reflector reflects the light inside the burner and passes through the sight glass connector to be captured by the sight glass assembly, enabling observation of the burner's interior. The clearance holes on the reflector prevent the reflector from obstructing the detection path of the flame detection device, achieving compatibility between monitoring and observation functions. 3. The switch valve is installed at the connection between the installation pipe and the flame detector pipe. Utilizing the valve's on / off function, the valve is closed when the component needs maintenance, directly isolating the passage between the installation pipe and the inside of the burner. This prevents toxic and harmful fumes from entering the pipe and maintenance area, avoiding contact with harmful gases for maintenance personnel and providing safety assurance for maintenance operations.

[0022] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0023] This application discloses a burner flame detection connector and sight glass connector assembly structure.

[0024] refer to Figure 1 and Figure 2A burner flame detection connector and sight glass connector assembly structure includes an installation connector 1, a flame detection connector 2, a sight glass connector 3, a flame detection installation connector assembly 4, a sight glass assembly 5, and a reflector 6. The installation connector 1 is connected to the inside of the burner, and the flame detection connector 2 is connected to the installation connector 1, with the flame detection connector 2 and the installation connector 1 being coaxially arranged. The sight glass connector 3 is integrally formed with the flame detection connector 2, and is located on the side wall of the flame detection connector 2 and connected to the flame detection connector 2, with the axis of the sight glass connector 3 perpendicular to the flame detection connector 2. The flame detection installation connector assembly 4 is installed at the end of the flame detection connector 2 away from the installation connector 1. The sight glass assembly 5 is installed at the end of the sight glass connector 3 away from the flame detection connector 2. The reflector 6 is located at the connection position between the flame detection installation steel pipe and the sight glass connector 3, and the reflector 6 is tilted to reflect light from inside the burner so that it passes through the sight glass connector 3. The reflector 6 has a clearance hole 61 to leave detection space after the flame detector is installed.

[0025] It also includes a switching valve 7 and a cooling air pipe 8. The switching valve 7 is located at the connection between the installation pipe 1 and the flame detection pipe 2. The two ends of the switching valve 7 are welded and fixed to the installation pipe 1 and the flame detection pipe 2 respectively, connecting them in series. When the component needs maintenance, the valve is closed to directly isolate the passage between the installation pipe 1 and the inside of the burner, preventing toxic and harmful flue gas in the burner from entering the pipe and maintenance area, avoiding contact with harmful gases by maintenance personnel, and providing safety for maintenance operations.

[0026] The cooling air duct 8 is connected to the side wall of the mounting duct 1. The axis of the cooling air duct 8 is perpendicular to the axis of the mounting duct 1. The end of the cooling air duct 8 away from the mounting duct 1 is connected to a compressed air source. Compressed air is introduced into the mounting duct 1 through the cooling air duct 8. The compressed air absorbs the heat of the entire component. There is no need to supply cooling air to the phase detection component and the sight glass component separately, thus saving the consumption of cooling air.

[0027] refer to Figure 1 and Figure 2 The fire detector connector 2 is fitted with a reflector fixing sleeve 9, which is a tube that runs through both ends. The end face of the reflector fixing sleeve 9 near the sight glass connector 3 is inclined and forms an acute angle with the end face of the sight glass connector 3. An annular protrusion 10 is integrally formed on the edge of the end face of the reflector fixing sleeve 9 near the sight glass connector 3. The reflector 6 contacts the annular protrusion 10 and is blocked and limited by the annular protrusion 10.

[0028] When installing the reflector 6, insert the reflector 6 axially from the end of the reflector fixing sleeve 9 away from the burner; slowly push the reflector 6 into the reflector fixing sleeve 9 until its edge contacts the annular protrusion 10 and is blocked, and cannot be pushed further; at this time, the reflector 6 and the end face of the sight glass connector 3 form an acute angle, ensuring that the light reflected by the reflector 6 passes through the sight glass connector 3 and is captured by the sight glass assembly 5; the annular protrusion 10 enables the quick installation and replacement of the reflector 6.

[0029] refer to Figure 1 and Figure 2 The flame detector mounting connector assembly 4 includes a flame detector mounting connector 41 and a sealing ring 42 for mounting the flame detector. The flame detector mounting connector 41 is fixed to the end of the flame detector connecting pipe 2 away from the mounting pipe 1 by screwing on it, which facilitates quick assembly and disassembly. The sealing ring 42 is located at the contact surface between the flame detector mounting connector 41 and the mounting pipe 1. The sealing ring 42 enhances the sealing performance of the contact surface between the flame detector mounting connector 41 and the mounting pipe 1, effectively preventing gas leakage inside the burner and ensuring safe operation of the equipment.

[0030] refer to Figure 1 and Figure 2 The sight glass assembly 5 includes a pressure cap 51, a sight glass 52, and a sealing gasket 53. The pressure cap 51 is sleeved on the sight glass connector 3. The sight glass 52 is clamped between the pressure cap 51 and the sight glass connector 3. The sealing gasket 53 is disposed on the contact surface between the sight glass 52 and the sight glass connector 3. The sealing gasket 53 fills the gap between the contact surface between the sight glass 52 and the sight glass connector 3, improves the sealing performance, prevents gas leakage, and ensures the safe operation of the equipment.

[0031] The implementation principle of this application embodiment is as follows: by integrating the flame detection function and the sight glass function on the same mounting pipe 1, a compact assembly structure is formed; the mounting pipe 1 serves as a basic channel communicating with the inside of the burner, and the flame detection pipe 2 extends coaxially to directly install the flame detector, ensuring that the detection path reaches the combustion area directly; the sight glass pipe 3 reflects the light of the combustion status inside the burner to the sight glass observation end through the tilted reflector 6, realizing internal visual monitoring; an avoidance hole 61 is opened in the center of the reflector 6 to ensure that the detection field of the flame detector is not obstructed, thereby realizing that the monitoring and observation functions do not interfere with each other.

[0032] The added on / off valve 7 can isolate harmful gases inside the burner during maintenance, improving operational safety; the cooling air pipe 8 introduces compressed air to uniformly cool the entire component, simplifying the cooling structure and reducing compressed air loss.

[0033] In summary, this application integrates the dual functions of flame detection and sight glass observation, and has the advantages of compact structure, convenient installation, safe operation and easy maintenance.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
