[0001] The present invention relates to the technical field of coke removal for observation holes of power plant boilers, and particularly to a cleaning device for power plant boilers. Background Art

[0002] The observation hole of a power plant boiler is a special window provided on the boiler wall for observing the combustion condition of the internal flame of the boiler and the operating state of related equipment. Through the observation window, the operating personnel can directly see the flame shape, color, brightness, etc. inside the boiler, so as to judge whether the combustion is sufficient and stable, whether the position of the flame center is normal, and whether there are abnormal phenomena such as local overheating and flameout.

[0003] Most of the existing coke removal for the observation holes of power plant boilers is carried out manually. However, such a coke removal method not only takes time and effort, but also cannot clearly see the internal coke removal situation and requires a fire detection device for observation, and cannot clean it thoroughly, resulting in low efficiency. Therefore, an automatic coke removal device for the observation holes of power plant boilers is needed. The existing coke removal method for the observation holes of power plant boilers not only takes time and effort, but also cannot clearly see the internal coke removal situation and requires a fire detection device for observation, and cannot clean it thoroughly. At the same time, there is also the problem of low coke removal efficiency.

[0043] Specifically, the movable slot 201 is a rectangular slot opened on the upper end surface of the decoking device main body 1, as Figure 1 shown.

[0044] Specifically, the installation slot 202 is a rectangular slot opened on the side wall of the movable slot 201, and the length of the installation slot 202 is equal to the length of the movable slot 201.

[0045] Furthermore, a connecting block 206 is fixedly installed on the side surface of the moving block 205, and the roller 204 is in rolling contact with the connecting block 206. The moving block 205 and the connecting block 206 together form an L-shaped component.

[0046] Furthermore, the pushing assembly 2 further includes: an adapter block 213 and a pushing block 214; the pushing block 214 is fixedly connected to the moving block 205 through the adapter block 213; the pushing block 214 can be used as a force-applying component for pushing the moving block 205 to displace. As Figure 2 shown, one side of the moving block 205 is fixedly connected with an adapter block 213, and the other side of the adapter block 213 is fixedly connected with a pushing block 214. After placing the device at the designated position, pushing the pushing block 214 drives the connecting block 206 and the moving block 205 to move on the roller 204, and the rack 209 at the bottom drives the gear 210 to move, so that the cylinder 207 on one side of the connecting block 206 is pushed forward, and the front-end decoking cylinder 208 extends out of the cylinder 3 for decoking.

The other end of the rotating column 211 extends out of the outer surface of the main body 1 of the descaling device and is fixedly connected to a rotating disk 212. When the gear 210 rotates, the rotating disk 212 rotates synchronously with the gear 210.

[0050] In another specific embodiment of the present invention, a driving motor is fixedly installed outside the main body 1 of the descaling device. The output shaft of the driving motor passes through the side wall plate of the main body 1 of the descaling device and is fixedly connected to the gear 210. Further, it can drive the gear 210 to rotate. When the gear 210 rotates, it can drive the rack 209 and the connecting block 206 to displace, and finally realize the displacement drive of the descaling cylinder 208.

[0051] In this embodiment, as shown in Figure 1 , Figure 3 and Figure 4 shown, a limiting component 5 is arranged on one side of the main body 1 of the descaling device. The limiting component 5 includes: a position block 501, a fixing column 502, a cover plate 503, a clamping block 504 and a limiting hole 505.

[0052] Specifically, the position block 501 is fixedly connected to one side of the main body 1 of the descaling device, and there are two position blocks 501. A fixing column 502 is fixedly connected between the two position blocks 501. The outer part of the fixing column 502 is rotatably connected to a cover plate 503. A clamping block 504 is fixedly connected to the side surface of the cover plate 503. A limiting hole 505 is formed on the side surface of the rotating disk 212. When the cover plate 503 rotates, the clamping block 504 can be inserted into the limiting hole 505.

[0053] In this embodiment, after moving the connecting block 206 back to the end of the movable groove 201 of the main body 1 of the descaling device, rotate and press down the cover plate 503 to make the cover plate 503 rotate around the fixing column 502, and then embed the clamping block 504 into the limiting hole 505, which can limit the rotation of the rotating disk 212 and fix the rotating disk 212. Further, it can maintain the limiting and fixing of the connecting block 206 through the gear 210, and can prevent the end descaling cylinder 208 from protruding from the cylinder 3 when descaling is not carried out.

[0054] Further, a camera 7 is embedded at the front end of the descaling cylinder 208. Specifically, a concave groove 216 is provided at the front end of the descaling cylinder 208, and the camera 7 is installed in the groove 216.

[0055] Further, lead holes 215 for leading out cables are provided inside the descaling cylinder 208 and the cylinder 207.

[0056] Further, a detection module 8 and a display screen 9 are fixedly installed at the other end of the main body 1 of the defocusing device.

[0057] Further, the detection module 8 is built with a processor for converting the data collected by the camera 7 into a video signal and capable of being displayed through the display screen 9. In the present invention, the internal state information of the boiler is collected by the camera 7 and whether the defocusing of the fire viewing hole is completed is detected;

[0058] In this embodiment, as Figure 1 、 Figure 3 shown, a protective frame 6 is provided on one side of the main body 1 of the defocusing device, and the protective frame 6 is arranged outside the display screen 9. A camera 7 is fixedly connected inside the defocusing cylinder 208; the other end of the main body 1 of the defocusing device is fixedly connected with a detection module 8, and the display screen 9 is fixedly connected to the top of the detection module 8.

[0059] In a specific embodiment of the present invention, as Figure 1 、 Figure 3 shown, one end of the main body 1 of the defocusing device is fixedly connected with a cylinder 3, and a protective ring 4 is fixedly connected to the side surface of the cylinder 3. Preferably, the aperture of the cylinder 3 is the same as the aperture of the fire viewing hole; further, the diameter of the protective ring 4 is larger than the diameter of the cylinder 3. The protective ring 4 can cover the outside of the fire viewing hole to prevent the splashing of coke chips during defocusing from damaging the operator.

[0060] The cleaning method of the automatic cleaning equipment for the fire viewing hole of the power plant boiler of the present invention is as follows:

[0061] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, after the cylinder 3 is placed in alignment with the fire viewing hole, the push block 214 is pushed to displace, thereby driving the connecting block 206 and the moving block 205 to move on a row of rollers 204. The rack 209 at the bottom drives the gear 210 to rotate. At the same time, the connecting block 206 drives the cylinder 207 on one side to push forward, and the front defocusing cylinder 208 extends from the cylinder 3 to perform defocusing; after defocusing is completed, the connecting block 206 is moved back to the end of the main body 1 of the defocusing device, and then the cover plate 503 is pressed down so that the cover plate 503 rotates on the fixed column 502. By inserting the clamping block 504 into the limiting hole 505, the rotating disk 212 is fixed, and the gear 210 is kept fixed to limit the connecting block 206 and the defocusing cylinder 208.

[0062] In the present invention, by providing a pushing component 2, after placing the cleaning device at the position of the viewing hole, the pushing block 214 is pushed to drive the connecting block 206 and the moving block 205 to move on the roller 204. The rack 209 at the bottom drives the gear 210 to rotate. At the same time, the connecting block 206 drives the cylinder 207 to push forward, and the defocusing cylinder 208 at the front end extends out of the cylinder 3 to remove coke from the viewing hole, effectively improving the efficiency of coke removal and reducing the inconvenience of manual coke removal, enabling more efficient coke removal and improving the overall flexibility for easy operation. Moreover, in the present invention, by providing the roller 204 and the gear-rack mechanism, rolling friction occurs during the displacement of the connecting block 206, facilitating the application of the coke removal force.

[0063] In the present invention, by providing a limiting component 5, after moving the connecting block 206 back to the end of the coke removal device main body 1, the cover plate 503 is pressed down so that the cover plate 503 rotates on the fixed column 502. By inserting the clamping block 504 into the limiting hole 505 to fix the rotating disk 212, the gear 210 can be fixed, thereby realizing the limitation of the connecting block 206 and effectively fixing the pushing component 2 of the device to prevent the pushing component 2 from sliding out when coke removal is not performed.

[0064] Embodiment 2

[0065] In a specific embodiment of the present invention, an improved design is made for the defocusing cylinder 208 in Embodiment 1:

[0066] As Figure 5 、 Figure 6 shown, the defocusing cylinder 208 includes: a defocusing cylinder main body 2081, defocusing convex ridges 2082, and a coke scraping ring 2083; specifically, the defocusing convex ridges 2082 are strip-shaped convex ridges provided on the surface of the defocusing cylinder main body 2081; the coke scraping ring 2083 is rotatably installed on the surface of the defocusing cylinder main body 2081, and multiple arc-shaped coke scraping blades 2087 are provided on the surface of the coke scraping ring 2083.

[0067] Specifically, as Figure 5 、 Figure 6 shown, the defocusing convex ridges 2082 are strip-shaped convex ridges extending along the axial direction of the defocusing cylinder main body 2081, and the defocusing convex ridges 2082 extend to one end of the defocusing cylinder main body 2081.

[0068] Specifically, as Figure 5As shown, a plurality of defocusing ridges 2082 are equidistantly arranged on the circumferential surface of the defocusing cylinder main body 2081. When the pushing assembly 2 drives the defocusing cylinder 208 to linearly displace, that is, when the defocusing cylinder 208 extends from the cylinder 3 into the boiler viewing hole for defocusing, the plurality of defocusing ridges 2082 can divide the coke layer on the inner wall of the boiler viewing hole into multiple coke strips. In this embodiment, by arranging a plurality of equidistantly distributed defocusing ridges 2082, the coke layer on the inner wall of the boiler viewing hole can be divided, making it divided from the whole into multiple discontinuous local coke bodies, which is convenient for subsequent defocusing work and improves the defocusing efficiency.

[0069] Further, as Figure 8 , Figure 9 shown, a plurality of arc-shaped coke scraping blades 2087 are equidistantly arranged on the circumferential surface of the coke scraping ring 2083; preferably, the arc-shaped coke scraping blade 2087 is an S-shaped blade.

[0070] Further, as Figure 5 , Figure 6 shown, at least two coke scraping rings 2083 are arranged on the surface of the defocusing cylinder main body 2081. Preferably, three coke scraping rings 2083 are arranged.

[0071] In a specific embodiment of the present invention, the spacing between the arc-shaped coke scraping blades 2087 on the plurality of coke scraping rings 2083 is unequal (not shown in the figure). Preferably, the arrangement density of the arc-shaped coke scraping blades 2087 on the coke scraping ring 2083 closer to the defocusing ridge 2082 is smaller.

[0072] In a specific embodiment of the present invention, as Figure 5 shown, a plurality of arc-shaped rolling grooves 2086 are formed on the surface of the defocusing cylinder main body 2081, and the arc-shaped rolling grooves 2086 are spiral grooves.

[0073] Preferably, the plurality of arc-shaped rolling grooves 2086 are equidistantly distributed along the surface of the defocusing cylinder main body 2081.

[0074] Further, one end of the arc-shaped rolling groove 2086 extends to the end face of the defocusing cylinder main body 2081 close to the cylinder 207; in this embodiment, setting the port of the arc-shaped rolling groove 2086 on the end face of the defocusing cylinder main body 2081 can, on the one hand, facilitate the installation of the coke scraping ring 2083, and on the other hand, be conducive to the discharge of the debris generated by coke scraping from the port of the arc-shaped rolling groove 2086.

[0075] Further, as Figure 7As shown, a plurality of rolling balls 2085 are embedded and installed on the inner wall surface of the coking scraping ring 2083, and the rolling balls 2085 are in rolling fit with the arc-shaped rolling grooves 2086; when the rolling balls 2085 roll along the arc-shaped rolling grooves 2086, the coking scraping ring 2083 can roll circumferentially relative to the main body 2081 of the coke removal cylinder.

[0076] Further, the number of the rolling balls 2085 on the coking scraping ring 2083 is equal to the number of the arc-shaped rolling grooves 2086.

[0077] Further, a limiting ring 2084 is welded and fixed at the end of the main body 2081 of the coke removal cylinder; the limiting ring 2084 is used to prevent the coking scraping ring 2083 from detaching from the main body 2081 of the coke removal cylinder.

[0078] During installation, align the rolling balls 2085 on the coking scraping ring 2083 with the arc-shaped rolling grooves 2086, and push the coking scraping ring 2083 so that the rolling balls 2085 roll / slide along the arc-shaped rolling grooves 2086, and then the coking scraping ring 2083 is sleeved on the main body 2081 of the coke removal cylinder; install a plurality of coking scraping rings 2083 in the same way in sequence. After the installation of the plurality of coking scraping rings 2083 is completed, weld and fix the limiting ring 2084 at the end of the main body 2081 of the coke removal cylinder, so that the coking scraping ring 2083 can roll and displace along the main body 2081 of the coke removal cylinder and will not detach from the main body 2081 of the coke removal cylinder.

[0079] In a specific embodiment of the present invention, as Figure 6 、 Figure 7 shown, a material guiding outlet hole 2089 extending along the axial direction of the main body 2081 of the coke removal cylinder is provided on the main body 2081 of the coke removal cylinder; correspondingly, a plurality of radially extending material guiding channels 2088 are opened on the annular side surface of the main body 2081 of the coke removal cylinder; the material guiding channels 2088 are communicated with the material guiding outlet hole 2089, so as to be able to discharge the coke chips scraped off by the arc-shaped coking scraping edge 2087.

[0080] During use, by pushing component 2, the whole descaling cylinder 208 is driven to move back and forth, and then the main body 2081 of the descaling cylinder can be driven to reciprocate in the boiler viewing hole. When the main body 2081 of the descaling cylinder moves in the boiler viewing hole, the coke layer can be scraped off by the descaling ridges 2082 and the arc-shaped coke scraping blades 2087; during coke scraping, the descaling ridges 2082 can divide the coke layer into multiple coke layers, and then as the descaling cylinder 208 continues to move, when the arc-shaped coke scraping blades 2087 scrape the coke layer, they will be laterally offset under the action of the resistance of the coke layer, and the lateral offset force will push the scraping ring 2083 to rotate circumferentially to scrape the coke layer in the circumferential direction; finally, in order to prevent coke chips from clogging between the various components of the descaling cylinder 208, the scraped coke chips can enter the material guiding outlet hole 2089 through the material guiding channel 2088, and then be exported from the material guiding outlet hole 2089 to avoid descaling jams.

[0081] Preferably, as Figure 6 shown, the connection between the material guiding channel 2088 and the material guiding outlet hole 2089 adopts an arc transition.

[0082] Furthermore, in another specific embodiment of the present invention, the material guiding outlet hole 2089 can also be used as an air inlet. Specifically, an internal thread is provided at the end of the material guiding outlet hole 2089; the internal thread can be connected to the cold air blowing pipe; and then cold air can be blown into the material guiding outlet hole 2089, the material guiding channel 2088 and the gap between the descaling cylinder 208 and the boiler viewing hole, so as to cool the area of the boiler viewing hole and blow the coke chips generated by descaling into the boiler furnace cavity.

[0083] Preferably, the diameter of the limit ring 2084 is matched with the inner diameter of the boiler viewing hole, so that the coke chips will not be blown out in the reverse direction.

[0084] During implementation, when the push rod cold air blowing pipe blows air into the material guiding outlet hole 2089, the cold air can be blown into the material guiding channel 2088 from the material guiding outlet hole 2089, and then blown out from the material guiding channel 2088. Since gaps are left between the descaling ridges 2082 and between the arc-shaped coke scraping blades 2087, the coke chips accumulated between the descaling cylinder 208 and the boiler viewing hole can be blown into the boiler furnace cavity through the gaps between the adjacent descaling ridges 2082 and the gaps between the adjacent arc-shaped coke scraping blades 2087.

[0085] In this embodiment, the camera 7 can be installed using existing products, and a display screen is configured to display the internal state of the boiler; the use and connection of the camera and the display screen and the supply of cold air are all contents that can be achieved by those skilled in the art, and will not be elaborated in the present invention.

[0086] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
