Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler igniter support technology, and more specifically, to a support frame for a boiler oil gun igniter. Background Technology
[0002] As the most crucial component of the entire BMS combustion system, the quality of combustion directly or indirectly affects the stability of the boiler's main control system. In emergencies, when all coal feeders stop operating, the stable engagement of the oil gun serves as the last line of defense, playing a vital role. However, due to the furnace structure design of some units, where the oil gun and burner are installed in the same hole, the entire internal length of the burner is very long. This results in the oil gun and igniter requiring a long stroke of four to five meters to complete normal ignition. Such a long igniter structure can easily lead to an excessively heavy center of gravity or sagging, preventing smooth ignition and potentially causing unstable combustion or furnace MFT (Main Furnace Trip) protection activation.
[0003] Upon investigation, Chinese utility model patent CN217928867U discloses an oil gun igniter support frame, including an oil gun igniter and an igniter support body. The igniter support body is located in the middle of the outer wall of one side of the oil gun igniter. The igniter support body includes a first support block and a second support block. Addressing the problem of igniters frequently getting stuck inside long burners in partially counter-current furnace designs, this utility model designs a graphite block support block for the first support block and an aluminum alloy support block fixed to the cylinder body for the second support block. This provides support for the long-rod burner, ensuring that the igniter's control logic functions correctly each time the oil gun is ignited, thus providing protection. The support frame is fixed by a first support block and a second support block fixing plate. The fixing plate is set on the igniter, thus providing support in the middle section of the igniter. However, many oil gun igniters have a telescopic ignition gun, which can be accurately positioned during ignition and safely withdrawn after ignition. This method can be used to protect the ignition gun from damage during combustion in some large boilers. The fixing plate in this support frame is fixed on the first support block and the second support block. The fixing plate is set on the igniter and cannot be adapted to telescopic igniters.
[0004] Therefore, this utility model provides a support frame for a boiler oil gun igniter to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a support frame for boiler oil gun igniter, which has the advantage of wider applicability.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a support frame for a boiler oil gun igniter, comprising a support base fixedly mounted on the ignition electrode assembly at the mounting end and a support ring sleeved on an ignition gun at one end of the igniter. The support base is sleeved on the ignition gun. A telescopic rod is provided between the support ring and the support base. The support ring has several receiving grooves, one end of which faces the inner ring ignition gun. The receiving grooves are arranged in a circular array. A rotating rod is rotatably mounted in the receiving groove. A kit is fixedly sleeved on the rotating rod, and the kit abuts against the ignition gun.
[0007] As a preferred embodiment of this utility model, the sidewall of the kit is an inwardly concave arc shape.
[0008] As a preferred technical solution of this utility model, the arc-shaped sidewall of the kit fits into the sidewall of the ignition gun.
[0009] As a preferred embodiment of this invention, a gap is left between the inner wall of the support ring and the outer wall of the ignition gun.
[0010] As a preferred embodiment of this utility model, a gap is left between the inner wall of the support base and the outer wall of the ignition gun.
[0011] As a preferred technical solution of this utility model, multiple support rings are provided on the ignition gun, and the support rings are fixedly connected to each other.
[0012] As a preferred technical solution of this utility model, the telescopic rods are arranged in a ring array around the ignition gun. The telescopic rods include an inner rod rotatably connected to the side of the support ring near the support base, and an outer rod sleeved on the inner rod. The end of the outer rod away from the inner rod is fixedly connected to the support base. The inner rod and the outer rod are connected by threads.
[0013] As a preferred embodiment of this utility model, a reinforcing plate is fixedly sleeved on the support base, and the reinforcing plate is fixedly connected to the ignition electrode assembly.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model sets up a support base, which is fixed to the ignition electrode assembly at the installation end of the boiler oil gun igniter by bolts and sleeved around the ignition gun. The support ring is sleeved on the ignition gun. The telescopic rod between the support base and the support ring is used to fix the support ring. The support ring is set in the middle section of the ignition gun, which can prevent it from being too close to the cavity where the combustion reaction occurs in the boiler and being damaged during long-term use. It can also support the ignition gun and prevent the end of the ignition gun from drooping due to being too long and deviating from the original ignition position.
[0016] 2. By setting up a kit, the rotating rod in the accommodating groove is used to support the kit. During the process of the ignition gun extending and retracting, the outer wall of the ignition gun drives the kit and the rotating rod to rotate, which can reduce the friction between the kit and the support ring. While the bracket supports the ignition gun, it also reduces the wear of the ignition gun, which is beneficial to the long-term use of the support frame for the boiler oil gun igniter.
[0017] 3. This utility model, by setting a telescopic rod, allows the inner rod to be rotated to adjust the positional relationship between the inner and outer rods, thereby adjusting the length of the telescopic rod. This, in turn, allows the position of the support ring to be adjusted according to the length and telescopic movement of the ignition gun, thus providing better support. Attached Figure Description

[0025] 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.
[0026] like Figures 1 to 6As shown, this utility model provides a support frame for a boiler oil gun igniter, including a support base 1 fixedly mounted on the ignition electrode assembly at the mounting end and a support ring 2 sleeved on the ignition gun at one end of the igniter. The support base 1 is sleeved on the ignition gun. A telescopic rod 3 is provided between the support ring 2 and the support base 1. The support ring 2 has a plurality of receiving grooves 21. One end of the opening of the receiving groove 21 faces the direction of the inner ring ignition gun. The receiving grooves 21 are arranged in a circular array. A rotating rod 5 is rotatably mounted in the receiving groove 21. A fitting 51 is fixedly sleeved on the rotating rod 5. The fitting 51 abuts against the ignition gun.
[0027] Specifically, in use, the support base 1 is bolted to the ignition electrode assembly at the boiler oil gun igniter mounting end and fitted around the ignition gun. The support ring 2 is fitted onto the ignition gun. The telescopic rod 3 between the support base 1 and the support ring 2 is used to fix the support ring 2. The support ring 2 is located in the middle section of the ignition gun, which can prevent it from being too close to the combustion reaction chamber in the boiler and being damaged during long-term use. It can also support the ignition gun and prevent the end of the ignition gun from drooping due to excessive length and deviating from the original ignition position. The rotating rod 5 in the receiving groove 21 is used to support the kit 51. During the extension and retraction of the ignition gun, the outer wall of the ignition gun drives the abutting kit 51 and the rotating rod 5 to rotate. The support ring 2 and the support base 1 do not contact the outer wall of the ignition gun, which can reduce the friction between them. This bracket supports the ignition gun while reducing the wear of the ignition gun, which is beneficial to the long-term use of the support frame for the boiler oil gun igniter.
[0028] Furthermore, the sidewall of the kit 51 is an inwardly concave arc shape, which can increase the contact area with the outer wall of the ignition gun.
[0029] Furthermore, the arc-shaped sidewall of the kit 51 fits into the sidewall of the ignition gun, thereby increasing the contact area between the kit 51 and the outer wall of the ignition gun and maintaining stability.
[0030] It is worth noting that a gap is left between the inner wall of the support ring 2 and the outer wall of the ignition gun. This is to prevent the support ring 2 from rubbing against the ignition gun and causing wear.
[0031] It should be noted that a gap is left between the inner wall of the support base 1 and the outer wall of the ignition gun. This is to prevent the support base 1 from rubbing against the ignition gun and causing wear and tear.
[0032] Furthermore, multiple support rings 2 are provided on the ignition gun, and all support rings 2 are fixedly connected to each other. The number of support rings 2 can be appropriately increased according to the length of the ignition gun, so that the support frame can provide more stable support for the ignition gun.
[0033] Furthermore, the telescopic rods 3 are arranged in a ring array around the ignition gun. The telescopic rods 3 include an inner rod 31 rotatably connected to the side of the support ring 2 near the support base 1, and an outer rod 32 sleeved on the inner rod 31. The end of the outer rod 32 away from the inner rod 31 is fixedly connected to the support base 1. The inner rod 31 and the outer rod 32 are connected by threads.
[0034] Specifically, rotating the inner rod 31 of the telescopic rod 3 can adjust the positional relationship between the inner rod 31 and the outer rod 32, thereby adjusting the length of the telescopic rod 3. This allows the position of the support ring 2 to be adjusted according to the length and telescopic movement of the ignition gun, thus providing better support.
[0035] It should be noted that a reinforcing plate 4 is fixedly sleeved on the support base 1, and the reinforcing plate 4 is fixedly connected to the ignition electrode assembly. The reinforcing plate 4 can maximize the contact area with the ignition electrode assembly, thereby increasing the stability of the support base 1.
[0036] Working principle and usage process of this utility model:
[0037] In use, the support base 1 is bolted to the ignition electrode assembly at the boiler oil gun igniter mounting end and fitted around the ignition gun. The support ring 2 is fitted onto the ignition gun. The telescopic rod 3 between the support base 1 and the support ring 2 is used to fix the support ring 2. The support ring 2 is located in the middle section of the ignition gun, which can prevent it from being too close to the combustion reaction chamber in the boiler and being damaged during long-term use. It can also support the ignition gun and prevent the end of the ignition gun from drooping due to excessive length and deviating from the original ignition position. The rotating rod 5 in the receiving groove 21 is used to support the kit 51. During the extension and retraction of the ignition gun, the outer wall of the ignition gun drives the kit 51 and the rotating rod 5 to rotate. The support ring 2 and the support base 1 do not contact the outer wall of the ignition gun, which can reduce the friction between them. This bracket supports the ignition gun while reducing the wear of the ignition gun, which is beneficial to the long-term use of the support frame for the boiler oil gun igniter. The rotating rod 5 and the kit 51 are arranged in a ring array, so that the support around the ignition rod is relatively balanced. Rotating the inner rod 31 of the telescopic rod 3 adjusts the positional relationship between the inner rod 31 and the outer rod 32, thereby adjusting the length of the telescopic rod 3. This allows the position of the support ring 2 to be adjusted according to the length and telescopic movement of the ignition gun, thus providing better support. The reinforcing plate 4 maximizes the contact area with the igniter electrode assembly, increasing the stability of the support base 1.
