Technical Field
[0001] This utility model belongs to the field of leak-sealing structure technology, and relates to a prefabricated device for rapid leak sealing of boiler burners in thermal power plants. Background Technology
[0002] Boiler burners are devices in thermal power plants used to mix fuel and air for combustion. During boiler operation, burners are prone to leaks due to prolonged exposure to high temperatures, high-speed airflow, and the scouring and erosion of fuel particles. These leaks not only reduce boiler thermal efficiency and increase energy consumption but can also cause flue gas leaks, affecting the on-site environment and the health of operators. In severe cases, they can even threaten the safe and stable operation of the boiler.
[0003] Currently, the main methods for repairing leaks are to temporarily create leak-sealing molds or use on-site welding. These methods require a long preparation time and furnace shutdown time, resulting in a long operation time. Utility Model Content

[0023] 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.
[0024] Please see Figures 1-3 This utility model discloses a prefabricated device for rapid leak sealing of boiler burners in thermal power plants, including a side plate 1. The side plate 1 is rectangular and multiple side plates 1 are provided. A slide rail 2 is provided on the side of the side plate 1, and a slider 3 is fixedly installed at the end of the side plate 1. During installation, the slider 3 can be slidably installed in the slide rail 2 so that multiple side plates 1 are connected end to end in a ring. One of the side plates 1 is provided with a pouring port 4.
[0025] Specifically, during the combustion of fuel and air in the burner, the weight of the pulverized coal causes significant friction between the pulverized coal and the bottom of the casing, resulting in most leaks originating from the bottom. By installing a slide rail 2 and a slider 3, during installation, the slider 3 is inserted into the slide rail 2, causing multiple side plates 1 to connect end-to-end in a ring shape. The slide rail 2 is located on the inner side. The ring formed by the side plates 1 is placed at the leak location and fixed. High-molecular-weight polymer sealing material is then filled through the pouring port 4. After the sealing material solidifies, the leak is repaired.
[0026] In this way, by setting the slide rail 2 and the slider 3, the ring formed by the side plate 1 can be adjusted in size by sliding the slider 3, which is convenient for dealing with different leaks, simplifies the process of making molds when repairing leaks, and saves working time.
[0027] In some feasible configurations, side plate 1 is a rectangular thin plate, slide rail 2 can be a rectangular strip with T-slots, and slider 3 is a T-shaped block. In actual use, where there is ample operating space at some burner leak locations, pouring inlet 4 may not be required; filling can be done from above the annular structure formed by side plate 1. The ring formed by side plate 1 can be fixed to the leak location by welding or other methods. After adjusting the ring size, the excess portion of the side plate can be bent to the adjacent side.
[0028] As a specific embodiment of the prefabricated device for rapid leak sealing of boiler burners in thermal power plants provided in the application, the side plate 1 is an L-shaped bent piece, and the slide rail 2 and the slider 3 are respectively arranged on both sides of the bend of the side plate 1.
[0029] Overall, by setting the side plate 1 as an L-shaped bent piece, the slider 3 can be installed on a larger plane, simplifying the installation method of the slider 3.
[0030] Furthermore, the slide rail 2 includes two mirror-symmetrically arranged L-shaped plates 21, and the slider 3 includes a bolt 31 and a nut 32. The slider 3 can slide through the side plate 1, and the end of the bolt 31 can be slidably installed between the two L-shaped plates 21.
[0031] It should be understood that by setting bolts 31 and nuts 32, the two side plates 1 can be fixed together, which facilitates subsequent fixing work.
[0032] Furthermore, the end of bolt 31 is cylindrical, and when bolt 31 is installed on slide rail 2, the side of the end of bolt 31 fits against the inner side of slide rail 2.
[0033] It is understood that by setting the end of the bolt 31 to be cylindrical, the bolt 31 can rotate within the slide rail 2, thereby allowing the included angle between the two side plates 1 to be adjusted to accommodate the shape of the leak.
[0034] Furthermore, it also includes a support corner piece 22, which is a V-shaped bent piece, and rectangular grooves are provided on both sides of the support corner piece 22.
[0035] It should be understood that when the included angle between the two side plates 1 is less than 90 degrees, the side plates 1 are bent to form a suitable angle. When the included angle between the two side plates 1 is greater than 90 degrees, the two side plates 1 cannot support each other. The support corner piece 22 is set to support the two side plates 1 and stabilize the connection structure.
[0036] In some feasible methods, to reduce the possibility of bolt 31 coming loose, the diameter of the bolt 31 end is larger than the diameter of the shank. To reduce leakage when filling the sealing material, a plug 23 is provided on the outer side of the bend of the side plate 1. The plug 23 seals the gap between the outer side of the bend of the side plate 1 and the adjacent side plate 1 due to the slide rail 2.
[0037] As another specific embodiment of the prefabricated device for rapid leak sealing of boiler burners in thermal power plants provided in the application, it also includes a cover plate, which is installed on the side plate 1 away from the burner during installation.
[0038] It should be understood that by setting the cover plate, the side of the side plate 1 that is far from the leak point after forming a ring is sealed, which facilitates the sealing of leak points other than the bottom surface of the burner.
[0039] In some feasible methods, strong magnets are provided on the cover plate and side plate 1. This facilitates the removal of the cover plate after sealing is completed, saving materials.
[0040] 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.
