Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a tool for cleaning the interior of a boiler heating surface header. Background Art

[0002] Power plant boilers, also known as "power plant boilers", refer to medium and large boilers in power plants that provide a specified amount and quality of steam to steam turbines. They are one of the main thermal equipment in thermal power plants and are often matched with steam turbine generator sets of a certain capacity. They are mainly used for power generation, but in some special occasions they can also be used for external heating. Everyone knows that during the use of power plant boilers, it is easy for a large amount of oxide scale to adhere to the inner wall of the boiler, usually called "slagging". Once the inner wall of the boiler is slagging, if it is not cleaned in time, the effect of the boiler will definitely be reduced;

[0003] At present, the internal cleaning of the header is mainly done by hand, using clamps, using a vacuum cleaner, etc. When water accumulates inside the header, the above methods cannot be effectively cleaned. If the debris in the header is not thoroughly cleaned, the debris can easily enter the heating surface tubes after the unit is running, resulting in insufficient cooling of the tube wall and overheating and tube bursting. Therefore, a tool for cleaning the internal of the boiler heating surface header is proposed. Utility Model Content

[0036] Example 2

[0037] like Figure 1-Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the observation mechanism 3 includes a slide rail 301 and a reciprocating threaded rod 302, the back of the slide rail 301 is fixedly connected to the front of the fixed block 1, the sliding sleeve 305 is provided on the surface of the slide rail 301, a fixed plate 308 is fixedly provided on the top surface of the sliding sleeve 305, a camera 303 is fixedly provided on the inner top surface of the fixed plate 308, a fixed plate 308 is fixedly provided on the front of the fixed block 1, a motor 307 is fixedly provided on the right side of the fixed plate 308, the right side of the output end of the motor 307 is fixedly connected to the left side of the reciprocating threaded rod 302, a moving block 304 is provided on the surface of the reciprocating threaded rod 302, and the top surface of the moving block 304 is fixedly connected to the bottom surface of the sliding sleeve 305.

[0038] In this embodiment, by providing an observation mechanism 3, the internal situation of the coupling box can be viewed in real time during the cleaning process, avoiding the use of special instruments for inspection, thereby making the cleaning efficiency higher. During the observation process, by controlling the camera 303 to move back and forth left and right, the observation range can be wider, thereby making the observation effect better.

[0039] When in use, the two hand holes of the header are cut open during maintenance, and the two threaded rods 207 are manually controlled to rotate. When the two threaded rods 207 rotate, the two adjustment plates 202 can be adjusted through the two control blocks 206. After the length adjustment of the two adjustment plates 202 is completed, the fixed block 1 is placed inside the boiler through the hand hole. After the fixed block 1 enters the boiler heating surface header, the two extrusion plates 226 will move upward. When the two extrusion plates 226 move upward, the first extrusion block 221 can be driven to move upward through the two connecting rods 222. When the two baffles 221 move upward, the two second extrusion blocks 223 can make the two sliding plates 218 move backward. When the two sliding plates 218 move backward, the two inclined blocks 220 will be driven to move backward. When the two inclined blocks 220 move backward, the baffle 211 can be moved upward through the two elastic members 208. When the two baffles 221 move upward, the two sliding frames 215 can be extended to both sides through the two sets of springs 213. When the two sliding frames 215 extend to the left and right sides, they can adapt to different sizes of boiler heating surfaces. When the two pull rings 203 are manually pulled, the cleaning The pad 216 reciprocates back and forth on the boiler heating surface header, so that the boiler heating surface header can be cleaned. When the cleaning pad 216 moves back and forth, the oxide scale on the surface of the boiler heating surface can be pushed to the two hand holes. During the cleaning process, the motor 307 and the camera 303 are turned on. After the camera 303 is turned on, the cleaning situation inside the boiler heating surface header can be observed. After the motor 307 is turned on, the reciprocating threaded rod 302 can be driven to rotate. When the reciprocating threaded rod 302 rotates, the sliding sleeve 305 can be driven to reciprocate left and right through the moving block 304. When the sleeve 305 moves back and forth left and right, it can drive the camera 303 to move synchronously. After cleaning the contact, the fixed block 1 is moved to the hand hole, and the two sliding frames 215 are manually controlled to the middle side. After the two sliding frames 215 move to the middle, the two extrusion plates 226 will move downward. When the two extrusion plates 226 move downward, the two sliding plates 218 can be moved forward through the two elastic sheets 225. When the two sliding plates 218 move forward, the two baffles 211 can be moved downward through the two inclined blocks 220, thereby blocking the two sliding frames 215.

[0040] The above are only specific embodiments of the utility model, but the technical features of the utility model are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the utility model to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the utility model.
