Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply device technology, and in particular to a steam boiler water supply device. Background Technology
[0002] A steam boiler is a device that heats water and converts it into steam by burning fuels such as coal, natural gas, and oil. Types include fire-tube boilers and water-tube boilers. The former heats water through flue gas, while the latter heats water as it flows through tubes. However, regardless of the type, scale will inevitably form on the inner wall of the boiler.
[0003] Scale buildup in steam boilers is caused by minerals in the water being produced at high temperatures and deposited on the inner wall of the boiler. Scale not only reduces heat transfer efficiency but can also cause the boiler to overheat and be damaged. Therefore, it needs to be cleaned and treated regularly to avoid energy loss.
[0004] When scale forms in a steam boiler, a cleaning agent needs to be sprayed inside the boiler. Once the scale can be scraped off, it can be manually removed with a brush or steel wool to achieve the cleaning purpose. This manual process is not only time-consuming and labor-intensive, but may also result in incomplete cleaning. Therefore, in order to improve the cleaning effect, a steam boiler water supply device is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0033] Reference Figure 3 , Figure 4 and Figure 6 This utility model provides an embodiment of a steam boiler water supply device, including a top cover 1 for fixing the equipment. A housing 3 is fixedly connected to the bottom end of the top cover 1. A motor 4 is fixedly connected to the bottom end of the inner wall of the top cover 1. A gear 5 is fixedly connected to the output end of the motor 4. Gears 6 are provided on both the left and right ends of the gear 6. The outer walls of the two gears 6 mesh with the outer walls of the gear 6. A splined rod 7 is threadedly connected to the inner wall of the left gear 6. A rotating block 18 is rotatably connected to the top end of the splined rod 7. The rotating block 18 is rotatably connected to the splined rod 7. An electric telescopic rod 19 is fixedly connected to the top end of the rotating block 18. A fixing plate 8 is threadedly connected to the outer middle of the splined rod 7. The outer wall of the fixing plate 8 is... The machine housing 3 is connected to a nozzle 9, which is used to spray cleaning agent. A connecting block 10 is fixedly connected to the bottom end of the spline rod 7. Scrapers 11 are fixedly connected to all four sides of the connecting block 10. A connecting rod 12 is fixedly connected to the bottom end of the right gear 6. A stirring blade 13 is fixedly connected to all four sides of the connecting rod 12. A stirring box 14 is fixedly connected to the top of the machine housing 3. The stirring box 14 is used to stir and mix the cleaning agent. A water inlet 15 is fixedly connected to the right side of the stirring box 14. A water outlet pipe 16 is connected to the left side of the stirring box 14. The water outlet pipe 16 is used to transport the cleaning agent into the nozzle 9. A steam pipe 17 is connected to the left side of the machine housing 3. A recovery mechanism 2 is provided on the outer wall of the steam pipe 17. The recovery mechanism 2 is used to recover the steam from the steam pipe 17.
[0034] Specifically, a motor 4 is fixedly connected to the bottom of the inner wall of the top cover 1. The output end of the motor 4 drives the gear 5 to rotate. Since the gear 5 meshes with the gears 6 on the left and right ends, the gears 6 are rotated. To clean the scale inside the casing 3, a spline rod 7 is threadedly connected inside the gear 6 on the left side. When the spline rod 7 rotates with the gear 6, it drives the connecting block 10 at the bottom of the spline rod 7 to rotate, causing the scrapers 11 fixedly connected around the connecting block 10 to rotate. However, since the fixing plate 8 is fixed to the top of the casing 3, the spline rod 7 is restricted from shifting during rotation, thus achieving the rotation of the spline rod 7. The fixing plate 8 is internally threaded. When the right gear 6 rotates, the connecting rod 12 at its bottom rotates, which in turn causes the stirring blades 13 fixedly connected around the connecting rod 12 to rotate. This causes the stirring box 14 fixedly connected to the top of the housing 3 to stir, so that the cleaning agent passing through the water inlet 15 on the right side of the stirring box 14 is mixed evenly, thereby improving the cleaning effect. Then, the water is injected into the nozzle 9 through the water outlet pipe 16 connected to the left side of the stirring box 14. Because the water outlet of the nozzle 9 is offset inward, the water can be sprayed evenly onto the inner wall of the housing 3, thereby corroding the scale on the inner wall of the housing 3. This can be linked with the scraper 11 to improve the cleaning efficiency.
[0035] Reference Figure 2 , Figure 3 and Figure 5 The recycling mechanism 2 includes a condenser pipe 201, the inner wall of which is fixedly connected to the outer wall of the steam pipe 17. Water flows inside the condenser pipe 201. The rear end of the condenser pipe 201 is connected to a conveying pipe 202. The bottom end of the conveying pipe 202 is fixedly connected to a recycling box 203. The recycling box 203 is used to recycle condensate. The left side of the recycling box 203 is connected to a drain pipe 204. The top end of the drain pipe 204 is connected to the inside of the condenser pipe 201. The right side of the recycling box 203 is connected to a pumping pipe 205. The front end of the pumping pipe 205 is connected to a water pump 206. The water pump 206 is used to extract condensate from the recycling box 203. The left side of the water pump 206 is connected to a water injection pipe 207. The rear side of the recycling box 203 is fixedly connected to a valve 208.
[0036] Specifically, steam is recovered through a condenser pipe 201 fixedly connected to the outer wall of the steam pipe 17. Water flows inside the condenser pipe 201, cooling the steam in the steam pipe 17 and turning the gas into a liquid. Due to the inclination of the condenser pipe 201, the water on its inner wall flows into a conveying pipe 202 connected to the left end of the condenser pipe 201, and is then transported by the conveying pipe 202 to the recovery box 203, thus recovering the steam for reuse in the steam boiler. To avoid long-term use of the condenser pipe 201... Intermittent use weakens the steam condensation effect. By starting the water pump 206, the water pump 206 draws water from the recovery tank 203 connected to the left end through the water pumping pipe 205. This causes the water in the recovery tank 203 to be input into the water pump 206 through the water pumping pipe 205, and then transported to the condenser tube 201 through the water injection pipe 207 connected to the front end of the water pump 206. At the same time, the original cooling water inside the condenser tube 201 is injected into the recovery tank 203 through the drain pipe 204 under the pressure of the water pump 206, thereby replacing the cooling water inside the condenser tube 201.
[0037] Reference Figure 1 A fixed switch 20 is fixedly connected to the front side of the housing 3. The fixed switch 20 is electrically connected to the motor 4 and the water pump 206 respectively. Support columns 27 are fixedly connected to the front and rear sides of the bottom of the housing 3. The support columns 27 are used to support the housing 3. A bottom pad 28 is fixedly connected to the bottom of the support column 27. An observation window 21 is fixedly connected to the middle right side of the housing 3. The observation window 21 is used to observe the internal condition of the housing 3. Rivets 22 are threaded around the observation window 21.
[0038] Specifically, a fixed switch 20 is fixedly connected to the front side of the housing 3. The fixed switch 20 controls the motor 4 and the water pump 206. Support columns 27 are fixedly connected to the front and rear sides of the bottom of the housing 3. A bottom pad 28 is fixedly connected to the bottom of the support column 27. The bottom pad 28 is used to prevent the housing 3 from shaking. Rivets 22 are threaded around the observation window 21. The rivets 22 are used to fix the observation window 21.
[0039] Reference Figure 1 , Figure 4 and Figure 5 A thermometer 23 is fixedly connected to the front right side of the housing 3. The thermometer 23 is used to observe the water temperature inside the housing 3. A pressure gauge 24 is fixedly connected to the top of the thermometer 23. A dustproof box 25 is rotatably connected to the outer wall of the water inlet 15. The dustproof box 25 prevents dust from entering the mixing box 14. The inner wall of the dustproof box 25 is matched in size. The recycling mechanism 2 also includes a rubber ring 26. The right end of the rubber ring 26 is fixedly connected to the left end of the condenser tube 201.
[0040] Specifically, a thermometer 23 is fixedly connected to the front right side of the housing 3, and a pressure gauge 24 is fixedly connected to the top of the thermometer 23. The pressure gauge 24 is used to observe the internal pressure of the housing 3 to avoid excessive pressure. The recovery mechanism 2 also includes a rubber ring 26 to prevent leakage from the condenser tube 201.
[0041] Working principle: Start motor 4, motor 4 drives gear 5 to rotate, which in turn drives gear 6 on the left and right sides to rotate. Gear 6 on the left side drives spline rod 7 threaded connection. However, since the top of spline rod 7 is connected to rotating block 18, and the top of rotating block 18 is fixedly connected to electric telescopic rod 19, spline rod 7 can rotate while being displaced under the drive of electric telescopic rod 19. This causes connecting block 10 fixedly connected to the bottom of electric telescopic rod 19 to drive scraper 11 to scrape the inner wall of the housing 3. At the same time, gear 6 on the right side rotates, causing connecting rod 12 and stirring blade 13 to rotate in the stirring box 14. Due to the multiple stirring blades 13, the cleaning agent and water are better mixed during the stirring process, thereby improving the cleaning effect. Then the mixed cleaning agent is injected into nozzle 9 through water outlet pipe 16, and then sprayed onto the inner wall of housing 3 by nozzle 9, thereby cleaning the inner wall of housing 3. This works in conjunction with scraper 11 to improve cleaning efficiency.
[0042] The steam discharged from the steam pipe 17 is condensed by the condenser tube 201, thereby realizing the transformation of gas into liquid. The water produced by condensation is guided to the recovery tank 203 for storage through the delivery pipe 202, so as to recycle and reuse it. In order to avoid the cooling water inside the condenser tube 201 from decreasing its condensation effect during use, the water pump 206 is started. The water pump 206 draws cooling water from the recovery tank 203 through the water pumping pipe 205, and then injects it back into the condenser tube 201 through the water injection pipe 207. Under the pressure of the water pump 206, the cooling water that needs to be replaced is injected back into the recovery tank 203 through the drain pipe 204, so as to realize the recycling of the cooling water inside the condenser tube 201 and thus achieve the purpose of recovering and reusing the steam in the steam pipe 17.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
