Technical Field
[0001] This utility model relates to the field of hot water boilers, and more particularly to a water-saving device for hot water boilers. Background Technology
[0002] A hot water boiler is a device that heats water by burning fuel or using electricity to produce stable hot water. Its core function is to provide heat energy for heating systems or domestic water use. The boiler transfers heat to circulating water through heat exchange. After the water temperature rises, it is transported through pipes to radiators, underfloor heating systems, or water storage tanks to meet the building's heating or hot water needs.
[0003] Before a traditional hot water boiler is started from a cold state, in order to ensure that the water entering the boiler is hot, the cold water in the pipes and boiler body needs to be drained until hot water flows out. This part of the cold water is directly discharged into the sewer, resulting in a large waste of water resources. At the same time, when adding water to the boiler, the huge temperature difference caused by directly adding cold water will cause the boiler's metal parts to contract rapidly, generating huge thermal stress. Repeated thermal stress cycles will accelerate metal fatigue, leading to cracks, leaks, or even tube rupture. Utility Model Content

[0028] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a water-saving device for a hot water boiler, comprising: a bottom support plate 1 for bottom support; a heating boiler 2 fixedly connected to the top center of the bottom support plate 1; a water storage tank 10 fixedly connected to the rear left side of the top of the bottom support plate 1; a preheating water tank 5 fixedly connected to the front left side of the top of the bottom support plate 1; an external discharge frame 14 fixedly connected to the bottom end of the heating boiler 2; a water outlet pipe at the bottom end of the heating boiler 2 penetrating into the interior of the external discharge frame 14; and an internal device installed inside the external discharge frame 14. An adjustment and control assembly is used to achieve cold water recirculation and collection inside the boiler. A return water pipe 15 is fixedly connected to the left rear end of the external discharge frame 14. The outside of the return water pipe 15 penetrates into the interior of the water storage tank 10. A delivery water pipe 7 is fixedly connected to the front end of the water storage tank 10. The front end of the delivery water pipe 7 penetrates into the interior of the preheating water tank 5. A water supply pipe 3 is fixedly connected to the right side of the preheating water tank 5. The right side of the water supply pipe 3 penetrates into the interior of the heating boiler 2. The adjustment and control assembly includes a movable plate 21 that slides inside the external discharge frame 14. (Refer to...) Figure 5 A pull rod 25 is fixedly connected to the left side of the movable plate 21, and a sealing plate 26 is fixedly connected to the rear side of the pull rod 25. A sealing block 23 is fixedly connected to the right rear end of the movable plate 21. The sealing block 23 is nested in the right side slot of the outer drainage frame 14. An adjusting push rod 24 is fixedly connected to the right side of the outer drainage frame 14. The output end of the adjusting push rod 24 passes through the interior of the outer drainage frame 14 and is fixedly connected to the right side of the movable plate 21. A temperature sensor 20 is fixedly connected to the bottom end of the outer drainage frame 14. The temperature sensor 20 is electrically connected to the adjusting push rod 24. (Refer to...) Figure 6 A sealing ring 22 is fixedly connected inside the left slot of the outer discharge frame 14, and a density pad 27 is fixedly connected inside the sealing ring 22. A traction cover 12 is fixedly connected to the top of the heating boiler 2, and a steam transmission pipe 11 is fixedly connected to the top of the traction cover 12. The outer side of the steam transmission pipe 11 is fixedly connected to the top of the water storage tank 10. Multiple exhaust slots 9 are opened on the upper side of the outer side of the water storage tank 10. A second water pump 8 is fixedly connected to the outside of the water delivery pipe 7. A first water pump 4 is fixedly connected to the outside of the water supply pipe 3. An outer drain pipe 13 is fixedly connected to the right side of the rear end of the outer discharge frame 14.
[0029] The cooling water inside the heating boiler 2 is transferred to the external discharge frame 14 through the water outlet pipe at the bottom of the traction cover 12. The water, blocked by the moving plate 21, enters the water storage tank 10 through the left slot of the external discharge frame 14. Then, the second water pump 8 transports the water from the water storage tank 10 to the preheating water tank 5, and then back to the heating boiler 2 via the water inlet pipe 3 through the first water pump 4 for circulating heating. During this process, the drain valve of the heating boiler 2 remains closed, and the generated steam is transferred through the steam transfer... Pipe 11 leads into water storage tank 10 to realize heat energy recovery and utilization. After heating is completed, the water flows back into the external discharge frame 14. When the temperature sensor 20 detects that the temperature has reached the threshold, it triggers the adjustment push rod 24 to push the moving plate 21, so that the sealing block 23 is disengaged from the right slot. At the same time, the sealing sheet 26 and the density pad 27 are tightly attached. The high temperature water then flows out through the right slot of the external discharge frame 14 and is discharged through the external drain pipe 13. The entire system continuously replenishes water to the preheating water tank 5 through the water delivery pipe 7, forming a closed-loop water circulation system, which significantly improves the efficiency of water resource utilization and effectively reduces water waste.
[0030] Reference Figure 1 , Figure 2 and Figure 3 A support column 18 is used for the bottom of the preheating water tank 5. A heating rod 19 is fixedly connected inside the support column 18. A flipping and stirring assembly is installed on the outside of the support column 18 to achieve uniform heating of the water flow inside the preheating water tank 5. The flipping and stirring assembly includes a rotating sleeve 16 located outside the support column 18 and rotating around the outside of the rotating sleeve 16. Multiple stirring plates 17 are fixedly connected around the outside of the rotating sleeve 16 and rotating around the outside of the rotating sleeve 16 and inside the preheating water tank 5. A drive motor 6 is fixedly connected to the top center of the preheating water tank 5. The drive end of the drive motor 6 is fixedly connected to the top of the rotating sleeve 16. Multiple slots are opened on the lower side of the outside of the rotating sleeve 16. Multiple through slots are opened around the outside of the support column 18 to achieve better heat discharge from the heating rod 19.
[0031] During the heating process, the water supply pipe 7 continuously injects water into the preheating water tank 5. At this time, the system starts the drive motor 6 and the heating rod 19. The heating rod 19 radiates high temperature to preheat the water in the preheating water tank 5. The drive motor 6 drives the rotating sleeve 16 to rotate, causing multiple external stirring plates 17 to rotate synchronously, fully agitating the water in the tank. At the same time, the slots opened on the outside of the support column 18 ensure that the water comes into full contact with the heating rod 19, enhancing the heat transfer efficiency. This preheating system effectively increases the initial temperature of the water, which not only significantly improves the heating efficiency of the heating boiler 2, but also ensures the safety and stability of the boiler heating process through preheating control.
[0032] Working Principle: The cooling water inside the heating boiler 2 is transferred to the outer discharge frame 14 via the outlet pipe at the bottom of the traction cover 12. Due to the obstruction of the moving plate 21, the water entering the outer discharge frame 14 flows through the slot on the left side of the outer discharge frame 14 into the water storage tank 10. At this time, the second water pump 8 transfers the water from the water storage tank 10 to the preheating water tank 5, and then the first water pump 4 transfers the water through the water inlet pipe 3 back to the heating boiler 2 to heat the water inside. Simultaneously, the valve of the next water pipe in the heating boiler 2 is closed. The generated steam is drawn upwards and transferred to the water storage tank 10 through the steam transmission pipe 11, improving water conservation. When the water inside the heating boiler 2 has finished heating, the water pipe discharges the water back into the outer discharge frame 14. The temperature sensor 20 detects that the internal temperature of the outer discharge frame 14 has risen to a threshold, and adjusts the pressure accordingly. Rod 24 sends a signal, thereby generating a forward thrust on the moving plate 21. The sealing block 23 disengages from the slot on the right side inside the outer drain frame 14, while the sealing sheet 26 adheres to the outside of the density pad 27. The high-temperature water flows out through the slot on the right side of the outer drain frame 14 to the outer drain pipe 13. During the heating process, the water flow transmitted to the preheating water tank 5 by the water delivery pipe 7 is activated. At this time, the drive motor 6 and the heating rod 19 are started. The heating rod 19 generates high temperature to the outside, thereby heating the water flow inside the preheating water tank 5. The drive motor 6 drives the rotating sleeve 16 to rotate, thereby agitating the water flow inside the preheating water tank 5 by rotating multiple external stirring plates 17. The slot opened on the outside of the support column 18 allows the water flow to contact the outside of the heating rod 19, thereby improving the contact heat effect, improving the preheating effect of the device, ensuring that the water flow transmitted to the heating boiler 2 has a certain temperature, improving the heating efficiency of the boiler, and ensuring the safety of boiler heating.
