Description

Technical Field

[0001] This utility model belongs to the field of burner technology, specifically relating to a burner ignition sensing installation device. Background Technology

[0002] In the field of gas combustion equipment, ignition sensing devices are one of the core components that ensure the safe and stable operation of the combustion system. Their main function is to accurately detect the ignition status and feed it back to the control system to ensure the reliability of the ignition process and timely protection after flameout. Among them, the ignition sensing needle, as a key actuator of the device, needs to be fixed in the preset position of the burner through a specific installation structure to ensure the accuracy and stability of the sensing signal.

[0003] Currently, to ensure secure fixing and precise positioning of the ignition needle and sensing needle within the burner, existing installation structures generally employ a multi-step installation method using screws and springs. First, the sensing needle must be passed through a pre-drilled hole in the burner. Then, a spring applies pre-tightening force to the sensing needle to eliminate assembly gaps. Finally, a screw is threaded through the spring and connected to the mounting base to complete the fixation. This process involves multiple assembly steps, increasing the complexity of manual operation, resulting in low installation efficiency and making it difficult to meet the needs of large-scale production. Furthermore, the screw and spring require high precision in their fit. If uneven spring compression or deviations in screw tightening occur during assembly, the sensing needle may tilt or loosen, affecting the detection accuracy of the sensing signal and even posing safety hazards, making the process quite inconvenient.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] This utility model provides, for example Figure 1-4 A burner ignition sensor mounting device is shown, which is applied to a burner 1 and includes: a base 2, which is adapted to be installed at the bottom of the burner 1 and screwed to the burner 1;

[0025] Mounting slot 3, the mounting slot 3 is provided in two sets and both sets of mounting slot 3 are located in the base 2, the base 2 is provided with an ignition needle 4 and a sensing needle 5 integrally formed on the two sets of mounting slot 3 respectively;

[0026] Sleeve 6, which has two sets and is respectively sleeved on ignition needle 4 and sensing needle 5, is used to protect ignition needle 4 and sensing needle 5.

[0027] The mounting groove 3 is provided with an annular groove 7, and an arc-shaped retaining ring 8 is fixedly fitted at the bottom of the sleeve 6. After the bottom of the sleeve 6 is inserted into the mounting groove 3, the arc-shaped retaining ring 8 is engaged in the annular groove 7.

[0028] The burner 1 has two sets of openings, and the top end of the sleeve 6 is inserted into the openings. The bottom ends of the base 2 are connected to mounting feet 9. The mounting feet 9 at the bottom ends of the base 2 provide additional support and fixing points for the device. In actual installation, the mounting feet 9 can be fixed to the bottom support structure of the burner 1 or the equipment frame by bolts, and fixed to the top of the base 2 by screws to form a stable support system that corresponds to the top and bottom, effectively dispersing the vibration load generated when the device is working, and preventing the base 2 from deforming or loosening due to excessive force at a single point.

[0029] The base 2 is connected to a plurality of fixing ears 10 and the fixing ears 10 are provided with mounting holes 11. The base 2 is screwed to the burner 1 by bolts passing through the mounting holes 11.

[0030] Two sets of first nozzles 12 are connected to the base 2. A gas connector 13 is provided at the bottom of the base 2 and is connected to the two sets of first nozzles 12. A second nozzle 14 is connected to one end of the top of the base 2, and the bottom of the second nozzle 14 is also connected to the gas connector 13. Multiple sets of nozzles are connected to the gas connectors 13 respectively, and the gas supply can be adjusted according to the different working requirements of the burner 1, such as the firepower. When a high firepower is required, the two sets of first nozzles 12 and the second nozzle 14 can supply gas simultaneously, thereby increasing the combustion power by increasing the gas output. When a low firepower is required, the gas supply to some nozzles can be shut off, leaving only one or two sets of nozzles working, thus adjusting the firepower.

[0031] In the manufacturing process of the base 2, the ignition needle 4 and the sensing needle 5 are connected to the base 2 using an integrated injection molding process. First, the lower ends of the ignition needle 4 and the sensing needle 5 that meet the specifications are fixed in the preset position of the injection mold to ensure that the verticality and spacing of the needles meet the design standards. Then, high-temperature molten plastic material (such as high-temperature resistant PBT or nylon material) is injected into the mold. The plastic material flows in the mold and wraps around the lower ends of the ignition needle 4 and the sensing needle 5. After the plastic cools and solidifies, the ignition needle 4 and the sensing needle 5 are tightly integrated with the base 2 into a whole. This process avoids errors in later assembly and ensures the accuracy of the needle position and the stability of the structure. The device is based on the burner 1. The base 2 is fixed to the bottom of the burner 1 by screws. The mounting holes 11 on the fixing ears 10 are used with bolts to tightly connect the base 2 and the burner 1 to prevent relative displacement during operation. The mounting feet 9 cooperate with the support structure of the burner 1 to further enhance the stability of the overall device.

[0032] The inner diameter of the sleeve 6 is slightly larger than the outer diameter of the ignition needle 4 and the sensing needle 5, ensuring that the needle body can be smoothly inserted into the sleeve 6. An arc-shaped retaining ring 8 is provided on the lower outer side of the sleeve 6, and a corresponding annular retaining groove 7 is provided on the inner wall of the mounting groove 3. The arc-shaped retaining ring 8 is made of stainless steel or alloy steel with a certain degree of elasticity and high strength. When the sleeve 6 is placed on the needle body and pressed down, the arc-shaped retaining ring 8 made of stainless steel or alloy steel will deform slightly due to the force and smoothly enter the mounting groove 3. When it reaches the position of the annular retaining groove 7, the arc-shaped retaining ring 8 returns to its original shape and is locked into the groove. This design achieves a secure connection between the sleeve 6 and the mounting groove 3, thereby stably mounting the sleeve 6 onto the ignition needle 4 and the sensing needle 5. This snap-fit ​​structure is not only easy to install but also reliable, and will not easily fall off during the operation of the burner 1. The sleeve 6 is made of high-temperature resistant and aging-resistant ceramic material or modified PPS plastic. The ceramic material has excellent high-temperature resistance (can withstand temperatures above 800℃) and insulation, which can effectively block the high-temperature radiation of the flame, protect the ignition needle 4 and the sensing needle 5 from high-temperature damage, and ensure the long-term stable use of the sleeve 6.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
