Description

Technical Field

[0001] This utility model relates to the field of nozzle slag removal technology, specifically a slag removal device for gasifier burner nozzles. Background Technology

[0002] The slag removal tool for gasifier burners is used to clean the slag buildup at the burner inlet of the gasifier, ensuring unobstructed and normal operation of the burner. As the combustion process proceeds, the high temperature inside the furnace causes deposits and residues to form in the furnace chamber. These residues can clog the burner inlet, affecting the efficiency and safety of the gasifier. The slag removal tool removes these slags mechanically or by spraying, ensuring smooth airflow, preventing equipment malfunctions and incomplete combustion, thereby improving the working efficiency of the gasifier and extending its service life.

[0003] Existing ash removal tools for gasifier burners have significant drawbacks. Their structural design lacks adjustability, failing to adapt to the diameter, depth, and other dimensional parameters of burners of different sizes. This makes it difficult for the tools to precisely fit the inner wall of the burner when dealing with equipment of varying sizes, easily resulting in blind spots during cleaning. Furthermore, the lack of a universal adaptation mechanism necessitates frequent replacement of specialized tools, increasing operating costs and impacting work efficiency due to time-consuming tool switching. In addition, non-targeted cleaning may damage the inner wall of the equipment, posing safety hazards. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a gasifier burner nozzle slag removal device that can adapt to burner nozzles of different specifications, so as to accurately fit the inner wall to remove slag accumulation, reduce blind spots in cleaning, avoid frequent tool changes, reduce operating costs and improve operational safety and efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a gasifier burner slag removal device, including a connecting ring and a cleaning component. The cleaning component includes a handle set inside the connecting ring, a connecting rod set at one end of the handle, a squeezing plate set at the end of the connecting rod away from the handle, multiple first expansion plates set around the periphery of the squeezing plate, and guide grooves that cooperate with the protruding parts of the side wall of the squeezing plate are opened inside the multiple first expansion plates. A cleaning tooth is set at one end of the first expansion plate, and a fixing component is set on the other side of the connecting ring.

[0006] In a preferred embodiment, one side of the connecting ring is provided with multiple second expansion plates, which are located around the multiple first expansion plates. A fixing component is provided at the end of the second expansion plate away from the connecting ring.

[0007] In a preferred embodiment, the fixing component includes an arc-shaped connecting plate disposed at the other end of the second expansion plate away from the connecting ring, and multiple connecting plates are provided with expansion grooves located on the same annular trajectory, with a sliding plate slidably disposed in the expansion groove.

[0008] In a preferred embodiment, the sliding plate is disposed between two adjacent connecting plates, with both ends of a single sliding plate extending into the outer expansion grooves of the two adjacent connecting plates, respectively.

[0009] In a preferred embodiment, the top surface of the connecting plate is provided with an adjustment groove located in the radial direction of the connecting plate, and the end of the sliding plate extending into the expansion groove is provided with a sliding knob, which passes through the adjustment groove.

[0010] In a preferred embodiment, the outer arc surface of the connecting plate is provided with a fixing plate, and the fixing plate has a connection port.

[0011] In a preferred embodiment, a support ring is provided at the end of the first outer expansion plate away from the cleaning teeth, and the support ring is rotatably disposed on the inner wall of the connecting ring.

[0012] The slag removal device at the burner inlet of a gasifier provided by this utility model, by adopting the above-described structure, has the following beneficial effects: (1) By using the inclined surface matching structure of the inner extrusion plate of the connecting ring and the first outer expansion plate, the opening range of the first outer expansion plate can be flexibly adjusted by the push force of the handle, so that the cleaning teeth can accurately fit the inner wall of the burner orifice of different diameters. This solves the problem that existing tools need to be frequently replaced due to the lack of adjustability, greatly reduces tool switching time and cost, and avoids the risk of damage to the inner wall of the equipment by incompatible cleaning. (2) When the first expansion plate opens radially along the guide groove, its end cleaning teeth can evenly fit the inner wall of the burner mouth with the expansion amplitude. With the push-pull or rotation action of the handle, it can scrape off the slag at different depths in all directions. At the same time, the rotational cooperation structure of the support ring and the connecting ring ensures that the first expansion plate always fits the inner wall stably during the cleaning process, effectively solving the problem of blind spots in cleaning caused by the inaccurate fit of existing tools and improving the thoroughness of slag removal. (3) The sliding groove of the sliding plate and the connecting plate in the fixed component is designed to slide together. The diameter of the overall fixed structure can be adjusted by moving the sliding knob along the adjustment groove. This forms a coordinated adaptation mechanism with the expansion adjustment of the cleaning component, enabling the device to quickly complete the fixing and cleaning switching of different specifications of burner openings, reducing operation steps. The entire cleaning process can be completed by simply pushing, pulling or rotating the handle, reducing the complexity of operation and significantly improving the efficiency of slag removal.

[0015] like Figure 1-4 In a gasifier burner slag removal device, there is a connecting ring 1 and a cleaning component 2. The cleaning component 2 includes a handle 21 disposed inside the connecting ring 1. One end of the handle 21 is provided with a connecting rod 22. The end of the connecting rod 22 away from the handle 21 is provided with a pressing plate 23. Multiple first expansion plates 24 are provided around the pressing plate 23. The interior of each of the multiple first expansion plates 24 is provided with a guide groove 26 that cooperates with the protruding part of the side wall of the pressing plate 23. One end of the first expansion plate 24 is provided with a cleaning tooth 27. A fixing component 4 is provided on the other side of the connecting ring 1.

[0016] When the cleaning component 2 is working, the operator pushes the handle 21 inside the connecting ring 1. The force is transmitted to the squeezing plate 23 through the connecting rod 22. The squeezing plate 23 moves forward and pushes the first outer expansion plate 24 with the help of the inclined surface. The latter opens radially along the internal guide groove 26, so that the end cleaning teeth 27 are close to the inner wall of the pipe. By pushing, pulling or rotating the handle 21, the cleaning teeth 27 scrape off the accumulated slag. The opening range of the outer expansion plate is adjusted with the thrust to adapt to slag removal scenarios of different pipe diameters.

[0017] In a preferred embodiment, a plurality of second expansion plates 3 are provided on one side of the connecting ring 1. The plurality of second expansion plates 3 are located around the plurality of first expansion plates 24. A fixing component 4 is provided at the end of the second expansion plate 3 away from the connecting ring 1. The second expansion plate 3 in the connecting ring 1 is connected to the fixing component 4, and the fixing is assisted by structural support, thereby improving adaptability and stability.

[0018] In a preferred embodiment, the fixing component 4 includes an arc-shaped connecting plate 41 disposed at the other end of the second expansion plate 3 away from the connecting ring 1. Multiple connecting plates 41 are provided with expansion grooves 42 located on the same annular trajectory, and a sliding plate 43 is slidably disposed in the expansion grooves 42.

[0019] In a preferred embodiment, the sliding plate 43 is disposed between two adjacent connecting plates 41, and both ends of a single sliding plate 43 extend into the outer expansion grooves 42 on the two adjacent connecting plates 41 respectively.

[0020] When the fixed component 4 is in use, the connecting plate 41 is positioned by relying on the second outer expansion plate 3, and the sliding plate 43 in the outer expansion groove 42 can slide along the groove. By adjusting the extension length of the sliding plate 43, the width of the component can be changed, thereby adapting to flanges of different sizes and fixing the tool.

[0021] In a preferred embodiment, the top surface of the connecting plate 41 is provided with an adjustment groove 44 located in the radial direction of the connecting plate 41, and the end of the sliding plate 43 extending into the outer expansion groove 42 is provided with a sliding knob 45, which passes through the adjustment groove 44.

[0022] In a preferred embodiment, the outer arc surface of the connecting plate 41 is provided with a fixing plate 46, and the fixing plate 46 is provided with a connection port 47.

[0023] In a preferred embodiment, a support ring 25 is provided at the other end of the first outer expansion plate 24 away from the cleaning teeth 27, and the support ring 25 is rotatably disposed on the inner wall of the connecting ring 1.

[0024] The working principle of the slag removal device at the burner inlet of the gasifier disclosed in this utility model is as follows: like Figures 1-4 As shown, when the cleaning component 2 is working, the operator pushes the handle 21 inside the connecting ring 1. The force is transmitted to the squeezing plate 23 through the connecting rod 22. When the squeezing plate 23 moves forward, it pushes the first outward expansion plate 24 with the help of the inclined surface, causing it to open radially along the internal guide groove 26. The end cleaning teeth 27 then stick to the inner wall of the pipe. By pushing, pulling or rotating the handle 21, the cleaning teeth 27 can scrape off the accumulated slag. The opening range of the outward expansion plate is adjusted with the size of the pushing force, thus adapting to slag removal scenarios of different pipe diameters. The second outward expansion plate 3 on one side of the connecting ring 1 is connected to the fixing component 4 and fixed by structural support, which effectively improves the adaptability of the tool to different installation environments and the stability during operation. When the fixing component 4 is in use, the connecting plate 41 is positioned based on the second outward expansion plate 3 and expands outward. The sliding plate 43 inside the groove 42 can slide along the groove. By adjusting the extension length of the sliding plate 43, the width of the component can be changed to adapt to flanges of different sizes. The adjustment groove 44 of the connecting plate 41 allows the sliding knobs 45 at both ends of the sliding plate 43 to be inserted. The operator can turn the knob to make the sliding plate 43 slide precisely along the groove, thereby achieving fine adjustment of the component width and thus completing the adaptation and fixation of flanges of different sizes. The fixing plate 46 on the outside of the connecting plate 41 is connected to bolts and other fasteners through the connection port 47 to achieve a stable connection between the tool and the flange, meeting the installation needs of multiple scenarios. In addition, the support ring 25 at the end of the first expansion plate 24 is rotatably connected to the inner wall of the connecting ring 1, which can help adjust the length of the cleaning teeth 27 to better fit the irregular inner wall.
