Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of boiler superheaters, specifically a boiler superheater that is easy to clean. Background Technology
[0002] Boiler superheaters recover energy from boiler flue gas, heating the steam exiting the boiler into dry steam, which improves boiler thermal efficiency and helps prevent water hammer in the steam turbine. Regenerators recover energy from the exhaust steam of the steam turbine to heat the circulating water entering the boiler. The function of superheaters is to heat saturated steam to superheated steam at a certain temperature, thereby improving power plant efficiency.
[0003] The existing boiler superheater has a fixed structure. After long-term use, dust will accumulate inside the boiler superheater, making it difficult to clean. This will reduce the working efficiency of the boiler superheater during use, shorten its service life, and fail to meet the usage requirements of the boiler superheater.
[0004] Therefore, this utility model provides a boiler superheater that is easy to clean. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A boiler superheater that is easy to clean internally, comprising an air inlet pipe; a bottom pipe is connected to the top of the air inlet pipe, multiple guide pipes are connected to the top of the bottom pipe, a top pipe is connected to the top of the guide pipes, and an air outlet pipe is connected to the top of the top pipe; a scraper is slidably connected to the middle of the guide pipes, and a pull rope is fixedly connected to the top of the scraper; the pull rope is slidably connected to the top pipe; a movable plate is hinged to the front side of the bottom pipe. During operation, the air inlet pipe is first connected to the boiler, and gas enters the bottom pipe through the air inlet pipe, then passes through the guide pipes, the top pipe, and the air outlet pipe. After prolonged use, the inside of the conduit will accumulate a lot of impurities and dust. At this time, loosen the pull rope and let the scraper slide down the conduit. The scraper will scrape off the impurities attached to the inside of the conduit, and the dust and debris will fall to the bottom of the conduit. Open the movable plate to clean the dust and debris inside. After cleaning, pull the pull rope to return the scraper to the top of the conduit and keep it inside the top pipe. This will not block the conduit and affect the gas transmission. By setting up the scraper, pull rope, and movable plate, the inside of the conduit can be cleaned, and the fallen dust and debris will be cleaned out by the movable plate, thus ensuring that the inside of the conduit is clean and tidy.
[0007] Preferably, fixed plates are fixedly connected to both sides of the top tube, a rotating shaft is rotatably connected to the middle of the fixed plates, a winding drum is fixedly connected to the outside of the rotating shaft, the pull rope is fixedly connected to the winding drum, and a handle is fixedly connected to one end of the rotating shaft. The handle is rotatably connected to the fixed plates. During operation, each pull rope is connected to the winding drum. Rotating the handle can control multiple scrapers to clean the ducts simultaneously, scraping away the dirt attached inside the ducts. The scrapers can also be reset at the same time, thus reducing the operation of cleaning the ducts one by one, saving cleaning time and speeding up cleaning efficiency. By setting the rotating shaft, winding drum, and handle, the pull ropes and scrapers are controlled synchronously to clean each duct of the air intake pipe at the same time, reducing the tedious operation caused by cleaning the ducts one by one and improving the efficiency of duct cleaning.
[0008] Preferably, a turntable is fixedly connected to the outside of the handle, and a positioning pin is slidably connected to the middle of the turntable. The positioning pin is threadedly connected to the fixing plate. During operation, when the scraper is placed at the top of the conduit, in order to reduce the scraper from slipping, the positioning pin is engaged in the hole on the turntable and threadedly connected to the fixing plate. This can fix the handle and the shaft, reduce the handle or shaft from sliding on its own, which would cause the scraper to block the conduit and thus affect the gas conduction of the conduit.
[0009] Preferably, sliders are fixedly connected to both sides of the scraper, and grooves are provided on both sides of the conduit. The sliders are slidably connected to the grooves. During operation, the scraper can slide smoothly in and out of the conduit through the cooperation of the sliders and grooves. The linkage between the sliders and grooves can realize the positioning of the scraper in the conduit, reduce the phenomenon of the scraper tilting and getting stuck in the conduit, thereby blocking the conduit, causing the cleaning process to be stuck, or even affecting the gas conduction of the conduit.
[0010] Preferably, a screen is fixedly connected to the middle of the bottom pipe. The screen is inclined and during operation, the screen separates the bottom pipe. One side of the screen is the air inlet pipe, and the other side is the conduit pipe. This arrangement can reduce the dust and impurities falling from the conduit pipe and separate them from the air inlet pipe, thus reducing the impact of these dust and impurities on the air inlet pipe's gas transmission. The dust and impurities accumulate on one side of the screen, making it easy to clean them with the movable plate.
[0011] Preferably, the screen is provided with electromagnetic strips at both ends, and the electromagnetic strips are fixedly connected to the screen. When the screen is energized, the electromagnetic strips can guide the iron filings inside down, making the internal cleaning more thorough.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The boiler superheater described in this utility model is easy to clean. By setting up scrapers, pull ropes, and movable plates, the inside of the duct can be cleaned, and the fallen dust and debris are cleaned out by the movable plates, thus ensuring that the inside of the duct is clean and tidy.
[0014] 2. The boiler superheater described in this utility model is easy to clean internally. By setting a rotating shaft, a reel, and a handle, the pull rope and scraper are controlled simultaneously to clean each duct of the air inlet pipe at the same time, reducing the tedious operation caused by cleaning each duct individually and improving the efficiency of duct cleaning.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] like Figures 1 to 3As shown in the embodiment of this utility model, a boiler superheater that is easy to clean includes an air inlet pipe 1; the top of the air inlet pipe 1 is connected to a bottom pipe 11, the top of the bottom pipe 11 is connected to a plurality of conduits 12, the top of the conduits 12 is connected to a top pipe 13, the top of the top pipe 13 is connected to an air outlet pipe 14, a scraper 15 is slidably connected to the middle of the conduits 12, a pull rope 16 is fixedly connected to the top of the scraper 15, the pull rope 16 is slidably connected to the top pipe 13, and a movable plate 17 is hinged to the front side of the bottom pipe 11. During operation, the air inlet pipe 1 is first connected to the boiler, and the gas enters the bottom pipe 11 through the air inlet pipe 1, and then is conducted out through the conduits 12, the top pipe 13, and the air outlet pipe 14. The inside of the conduit 12 will accumulate a lot of impurities and dust. At this time, loosen the pull rope 16 and let the scraper 15 slide down the conduit 12. The scraper 15 scrapes away the impurities attached to the inside of the conduit 12, and the dust and debris fall to the bottom of the bottom tube 11. Open the movable plate 17 to clean the dust and debris inside. After cleaning, pull the pull rope 16 to return the scraper 15 to the top of the conduit 12 and stop it in the top tube 13. This will not block the conduit 12 and affect the gas transmission of the conduit 12. By setting up the scraper 15, pull rope 16, and movable plate 17, the inside of the conduit 12 can be cleaned, and the fallen dust and debris are cleaned out by the movable plate 17, thus ensuring that the inside of the conduit 12 is clean and tidy.
[0024] like Figures 1 to 3 As shown, a fixing plate 2 is fixedly connected to both sides of the top pipe 13. A rotating shaft 21 is rotatably connected to the middle of the fixing plate 2. A winding drum 22 is fixedly connected to the outside of the rotating shaft 21. The pull rope 16 is fixedly connected to the winding drum 22. A handle 23 is fixedly connected to one end of the rotating shaft 21. The handle 23 is rotatably connected to the fixing plate 2. During operation, each pull rope 16 is connected to the winding drum 22. Rotating the handle 23 can control multiple scrapers 15 to clean the duct 12 simultaneously, scraping away the dirt attached inside the duct 12. The scrapers 15 can also be reset at the same time. This reduces the operation of cleaning the duct 12 one by one, saves the cleaning time, and speeds up the cleaning efficiency. By setting the rotating shaft 21, winding drum 22, and handle 23, the pull ropes 16 and scrapers 15 are controlled synchronously to clean each duct 12 of the air intake pipe 1 at the same time, reducing the tedious operation caused by cleaning the duct 12 one by one and improving the cleaning efficiency of the duct 12.
[0025] like Figures 1 to 3As shown, a turntable 3 is fixedly connected to the outside of the handle 23, and a positioning pin 31 is slidably connected to the middle of the turntable 3. The positioning pin 31 is threadedly connected to the fixing plate 2. During operation, when the scraper 15 is placed on top of the guide tube 12, in order to reduce the scraper 15 from slipping, the positioning pin 31 is engaged in the hole on the turntable 3 and threadedly connected to the fixing plate 2. This can fix the handle 23 and the rotating shaft 21, reducing the self-slipping of the handle 23 or the rotating shaft 21, which would cause the scraper 15 to block the guide tube 12 and thus affect the gas conduction of the guide tube 12.
[0026] like Figures 1 to 4 As shown, sliders 4 are fixedly connected to both sides of the scraper 15, and grooves 41 are provided on both sides of the conduit 12. The sliders 4 and the grooves 41 are slidably connected. During operation, the scraper 15 can slide smoothly in and out of the conduit 12 through the cooperation of the sliders 4 and the grooves 41. The linkage between the sliders 4 and the grooves 41 can realize the positioning of the scraper 15 on the conduit 12, reduce the phenomenon of the scraper 15 tilting and getting stuck in the conduit 12, thereby blocking the conduit 12, causing the cleaning process to be stuck, or even affecting the conduction of gas in the conduit 12.
[0027] like Figures 1 to 5 As shown, a screen 5 is fixedly connected to the middle of the bottom pipe 11. The screen 5 is set at an angle. During operation, the screen 5 separates the bottom pipe 11. One side of the screen 5 is the air inlet pipe 1, and the other side is the conduit 12. This arrangement can reduce the dust and impurities that fall off the conduit 12 and separate them from the air inlet pipe 1, thus reducing the impact of these dust and impurities on the air inlet pipe 1 in transmitting gas. The dust and impurities accumulate on one side of the screen 5, making it easy to clean them through the movable plate 17.
[0028] like Figures 1 to 5 As shown, the screen 5 is provided with electromagnetic strips 6 at both ends. The electromagnetic strips 6 are fixedly connected to the screen 5. When working, after the electromagnetic strips 6 are energized, they can guide the iron filings inside down, making the internal cleaning more thorough.
[0029] Working principle: First, connect the air inlet pipe 1 to the boiler. Gas enters the bottom pipe 11 through the air inlet pipe 1, and then is conducted out through the conduit 12, top pipe 13, and outlet pipe 14. After long-term use, a lot of impurities and dust will accumulate inside the conduit 12. At this time, loosen the pull rope 16 to allow the scraper 15 to slide down the conduit 12. The scraper 15 scrapes away the impurities attached to the inside of the conduit 12, and the dust and debris fall to the bottom of the bottom pipe 11. Open the movable plate 17 to clean the dust and debris inside. After cleaning, pull the pull rope 16 to return the scraper 15 to the top of the conduit 12 and stop it in the top pipe 13. This will not block the conduit 12 and affect the transmission of gas. Gas is used to clean the inside of the conduit 12 by means of scrapers 15, pull ropes 16, and movable plates 17. Fallen dust and debris are removed by the movable plates 17, ensuring the conduit 12 remains clean. Each pull rope 16 is connected to a reel 22. Rotating the handle 23 controls multiple scrapers 15 to clean the conduit 12 simultaneously, removing adhering dirt. The scrapers 15 can also be reset simultaneously, reducing the need to clean each conduit individually, saving time and increasing cleaning efficiency. The rotating shaft 21, reel 22, and handle 23 synchronously control the pull ropes 16. 6. The scraper 15 cleans each conduit 12 of the intake pipe 1 simultaneously, reducing the tedious operation of cleaning each conduit 12 individually and improving the efficiency of cleaning the conduits 12. When the scraper 15 is placed on top of the conduit 12, to prevent the scraper 15 from slipping, the positioning pin 31 is engaged in the hole on the turntable 3 and threadedly connected to the fixing plate 2. This fixes the handle 23 and the rotating shaft 21, reducing the possibility of the handle 23 or the rotating shaft 21 sliding on its own, which could cause the scraper 15 to block the conduit 12 and thus affect the gas conduction of the conduit 12. The scraper 15 slides smoothly in and out of the conduit 12 through the cooperation of the slider 4 and the slide groove 41. The slider 4 and the slide groove 41 are linked together, which can... The scraper 15 is positioned to guide the conduit 12, reducing the possibility of the scraper 15 tilting and getting stuck inside the conduit 12, which could block the conduit 12, cause the cleaning process to stall, or even affect the gas transmission of the conduit 12. The screen 5 separates the bottom pipe 11, with the air inlet pipe 1 on one side of the screen 5 and the conduit 12 on the other side. This arrangement can reduce the amount of dust and impurities that fall off the conduit 12 and separate them from the air inlet pipe 1, thus reducing the impact of these dust and impurities on the gas transmission of the air inlet pipe 1. The dust and impurities accumulate on one side of the screen 5, making it easier to clean them by the movable plate 17. When the electromagnetic strip 6 is energized, it can guide the iron filings inside down, making the internal cleaning more thorough.
