[0002] During boiler burner operation, the flame detection sleeve is easily clogged by dust, carbon deposits, and other impurities. Clogged sleeves prevent the flame detection probe from accurately detecting the flame signal, leading to misjudgments by the control system and affecting the safe and stable operation of the boiler. Currently, the common method for addressing clogged flame detection sleeves is manual disassembly and cleaning. This method is cumbersome, requires significant manpower and time, and can easily damage the flame detection sleeve and probe during cleaning, reducing the equipment's lifespan.

[0003] The flame detection sleeve is a tubular component installed on the boiler burner to protect the flame detection probe and ensure its accurate detection of flame signals. Dust, carbon deposits, and other impurities generated during combustion can easily accumulate inside the flame detection sleeve, affecting the flame detection performance.

[0004] Manually disassembling and cleaning flame detector sleeves is inefficient, labor-intensive, and prone to damaging the equipment. Therefore, a simple and efficient boiler burner flame detector sleeve cleaner is needed to quickly clear blockages from the sleeves, reduce manual operation, and ensure the normal operation of the boiler flame detection system.

[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] The following is in conjunction with the appendix Figures 1 to 3 The specific embodiments of this utility model will be described in further detail.

[0027] Depend on Figures 1 to 3 As shown, this utility model includes a cleaner and a trolley 1 for assisting the movement of the cleaner. In order to facilitate gas impact unblocking of the flame detector sleeve, the cleaner includes a gas tank 2 for providing high-pressure gas. A connecting pipe 3 is connected to the upper side of the gas tank 2, and a unblocking pipe 4 is connected to the end of the connecting pipe 3 away from the gas tank 2. The gas tank 2 is detachably connected to the upper side of the trolley 1. A limiting mechanism 5 for limiting the gas tank 2 is provided on the upper side of the trolley 1. A rotatable moving mechanism 6 is provided on each of the left and right sides of the lower end of the trolley 1. Two buckles 21 for fixing the unblocking pipe 4 are provided on the rear side of the trolley 1. The buckles 21 are U-shaped, made of plastic, and have a certain elasticity. They can fit and limit cylindrical objects, such as plastic fixing buckles 21 or mop clips, which will not be described in detail here.

[0028] It should be noted that the gas tank 2 is a pressure vessel, and in this embodiment it is a high-pressure air tank 2, which is existing technology, such as the air tank 2 with model number LS-60-100. When using it, its specific model and volume can be determined according to actual needs, which will not be described in detail here.

[0029] When in use, the gas cylinder 2 can be limited on the trolley 1 by the limiting mechanism 5. At this time, the gas cylinder 2 can be moved by the moving mechanism 6 and the trolley 1, and then the gas cylinder 2 can be moved to a suitable position and the fire detection sleeve can be cleared by the unblocking pipe 4.

[0030] In addition, the limiting mechanism 5 can be adapted to different models of gas tanks 2, so that the trolley 1 can move different models of gas tanks 2.

[0031] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the adjustment of the unblocking air pressure, a first air valve 7 is provided on the upper side of the air tank 2. The air outlet of the first air valve 7 is connected to the connecting pipe 3. The connection between the first air valve 7 and the connecting pipe 3 is connected by a hose clamp. A second air valve 8 is provided in the middle of the unblocking pipe 4.

[0032] It should be noted that both the first air valve 7 and the second air valve 8 are straight-through ball valves, such as the KH model straight-through ball valve, which is existing technology and will not be described in detail here; the hose clamp is also existing technology and will not be described in detail here.

[0033] In use, the first air valve 7 is used to control the gas output switch of the gas tank 2, and the second air valve 8 is used to adjust the gas pressure of the gas sprayed from the unblocking pipe 4.

[0034] Furthermore, by Figures 1 to 3 As shown, in order to facilitate cleaning by staff, a bend 9 is provided on the side of the unblocking pipe 4 away from the connecting pipe 3;

[0035] When in use, the elbow 9 makes it easier for staff to clean the inner wall of the flame detector sleeve. An air nozzle, such as the MISUMI cone jet air nozzle, is also provided at the end of the elbow 9 away from the unblocking pipe 4. This is existing technology and will not be described in detail here.

[0036] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the detection of the air pressure inside the air tank 2, a pressure gauge 10 for detecting the internal pressure of the air tank 2 is provided on the upper side of the air pipe; the pressure gauge 10 is existing technology, such as a diaphragm pressure gauge, and the specific model and type can be determined according to the site conditions during actual use, which will not be described in detail here.

[0037] Furthermore, by Figures 1 to 3 As shown, in order to limit the different types of gas tanks 2, the limiting mechanism 5 includes multiple elastic bands 11, and the left and right sides of each elastic band 11 are fixedly connected to the trolley 1.

[0038] In use, by setting the deformation of the elastic band 11, a force can always be provided to the gas tank 2 in the direction of the trolley 1. When replacing the gas tank 2, the deformation of the elastic band 11 can also be adapted to limit the position of different models of gas tank 2.

[0039] Furthermore, by Figures 1 to 3As shown, in order to facilitate the replacement of gas cylinder 2 by staff, a fixing block 12 is fixedly connected to the middle of each elastic band 11, and an auxiliary opening 13 is opened in the middle of the upper side of each fixing block 12. Multiple extension rods 14 are fixedly connected to the front side of the lower part of the trolley 1, and an auxiliary groove 15 that matches the auxiliary opening 13 is opened on the lower side of each extension rod 14.

[0040] When in use, the extension rod 14 can increase the front-to-back distance of the bottom of the cart 1, reducing the probability of the gas tank 2 being unstable and shaking. When it is necessary to replace the air tube, each elastic band 11 can be pulled forward and downward so that the auxiliary opening 13 or the elastic band 11 can cooperate with the auxiliary slot 15. At this time, it is more convenient for one person to replace the gas tank 2.

[0041] Furthermore, by Figures 1 to 3 As shown, in order to achieve better transportation of gas tank 2, multiple flexible belts 16 are provided on the rear side of gas tank 2, and the left and right sides of each flexible belt 16 are fixedly connected to the trolley 1.

[0042] During use, depending on the model of the gas tank 2, the flexible belt 16 can always maintain a large contact surface with the gas tank 2, thereby reducing the risk of the gas tank 2 being bumped or knocked.

[0043] Furthermore, by Figures 1 to 3 As shown, in order to facilitate the transport of gas cylinder 2 by going up and down steps between different work areas, the moving mechanism 6 includes a rotating frame 17 and multiple rotating wheels 18. The rotating wheels 18 are evenly distributed on the outer side of the rotating frame 17, and each rotating wheel 18 is rotatably connected to the rotating frame 17.

[0044] The outer side of the rotating frame 17 is fixedly connected with auxiliary wheels 19 that correspond one-to-one with the rotating wheel 18, and the outer sides of multiple auxiliary wheels 19 are engaged with a belt 20.

[0045] When in use, the trolley 1 can move directly on a flat surface by means of the rotating wheels 18 that are in contact with the ground. When it is necessary to go up or down steps, due to the presence of the rotating frame 17, the rotating frame 17 will revolve under its own weight or pulling force when going up or down steps. At this time, the belt 20 will contact the end of the step tread, reducing the impact of the step on the rotating frame 17, thereby enabling the moving mechanism 6 to go up or down steps. It should be noted that the belt 20 does not rotate relative to the rotating frame 17; it is used to reduce the impact.

[0046] When using this utility model, the gas cylinder 2 is first limited on the trolley 1 by the limiting mechanism 5. At this time, the gas cylinder 2 can be moved by the moving mechanism 6 and the trolley 1, and then the gas cylinder 2 is moved to a suitable position and cleared by the unclog pipe 4 through the flame detector sleeve. In addition, the limiting mechanism 5 can be adapted to different models of gas cylinder 2, so that the trolley 1 can move different models of gas cylinder 2. The first gas valve 7 is used to control the gas output switch of the gas cylinder 2, and the second gas valve 8 is used to adjust the gas pressure of the gas sprayed from the unclog pipe 4.

[0047] This utility model features a novel structure, ingenious design, and simple and convenient operation. This design effectively facilitates gas impact unblocking of the flame detector sleeve, allows for easy adjustment of the unblocking gas pressure, facilitates cleaning by staff, and enables pressure monitoring inside the gas tank 2. It also achieves the purpose of limiting different models of gas tank 2, facilitates the replacement of gas tank 2 by staff, and achieves better transportation of gas tank 2. Furthermore, it adds the function of transporting gas tank 2 up and down steps between different work areas.

[0048] Although the present invention 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 invention should be included within the protection scope of the present invention.
