Description

Technical Field

[0001] This utility model relates to the field of boiler water supply technology, and in particular to an environmentally friendly boiler water supply device. Background Technology

[0002] In industrial production, district heating, and residential heating, boilers, as core heat energy conversion equipment, are highly dependent on water quality for their operational efficiency, safety, and lifespan. In boiler water supply systems, impurities such as silt, rust, scale crystals, and microbial flocs, if not effectively treated before entering the boiler, will gradually deposit on heating surfaces, pipe walls, and heat transfer elements. This leads to a significant decrease in heat exchange efficiency and increased fuel consumption. Furthermore, the accumulation of impurities can cause pipe blockages, localized overheating, and even boiler tube ruptures, seriously threatening production and environmental safety. Therefore, deep filtration of boiler water to remove impurities is crucial for ensuring efficient, safe, and environmentally friendly boiler operation.

[0003] Currently, impurity filtration in boiler water supply systems mainly relies on devices such as fixed filter screens, filter cartridges, or sedimentation tanks. Fixed filter screens intercept impurities through their pore size; however, over time, impurities accumulate on the screen surface, forming a clogging layer. This increases water flow resistance and reduces water supply pressure, affecting not only the stability of boiler feedwater but also requiring frequent shutdowns for disassembly and cleaning, severely impacting production continuity. For water sources with high impurity content, the filter screen may even become completely clogged in a short period, forcing the system to shut down. Therefore, this invention proposes a novel solution. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an environmentally friendly boiler water supply device that can solve the problem that the filter screen may even be completely blocked in a short time for water sources with high impurity content, forcing the system to shut down.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly boiler water supply device, including a boiler inlet pipe and a fixing frame installed on the boiler, with a water tank installed at the upper end of the fixing frame; The filter assembly is installed on the water tank. The filter assembly includes a filter box, which is fixedly connected to the upper left side of the water tank. The filter box contains a filter frame and an inlet pipe. The lower end of the inlet pipe is fixedly connected to a connecting cover, and a nozzle is rotatably connected to the inner side of the connecting cover. The nozzle has multiple first drainage channels near its axis and multiple curved second drainage channels near its edge. The outlet of the second drainage channels is inclined downward and forms an angle with the tangent of the nozzle edge.

[0006] Preferably, the upper end of the filter box is fixedly connected to the filter box cover by bolts, and the water inlet pipe is fixedly connected to the filter box cover.

[0007] Preferably, a flow guide frame is fixedly connected to the inner wall of the filter box, the filter frame is disposed inside the flow guide frame, and the flow guide frame and the filter frame are fixed together by bolts.

[0008] Preferably, a sealing gasket is provided between the flow guide frame and the filter frame.

[0009] Preferably, the lower end of the fixing frame is arc-shaped and fits against the surface of the boiler.

[0010] Preferably, a water pump is fixedly connected to the upper end of the water tank, and a first water pipe is fixedly connected to the water inlet end of the water pump.

[0011] Preferably, the first water pipe extends into the interior of the water tank. Preferably, an activated carbon filter box is fixedly connected to the outlet end of the water pump, and a second water pipe is fixedly connected to the end of the activated carbon filter box away from the water pump. Preferably, the upper end of the boiler inlet pipe is fixedly connected to a sealing flange by bolts. Preferably, the second water pipe is fixed to the sealing flange and extends into the interior of the boiler. Compared with the prior art, the beneficial effects of this utility model are: 1. This environmentally friendly boiler water supply device features a curved second drainage channel at the edge of the nozzle, with the outlet end angled to the tangent. When the water is sprayed out, the reaction force drives the nozzle to rotate autonomously. Combined with the direct water flow from the first drainage channel in the middle, it forms an all-round, dead-angle-free flushing effect. This design can continuously clean impurities on the surface of the filter frame, avoiding the clogging problem caused by the accumulation of impurities in traditional fixed filters, maintaining a stable water flow rate, and ensuring stable water supply pressure.

[0012] 2. This environmentally friendly boiler water supply device uses a primary filtration system to intercept solid impurities such as silt and rust through a filter frame, and a secondary filtration system to adsorb odors, organic pollutants, and fine particles through an activated carbon filter box. The two-stage filtration works synergistically to significantly improve water purification and effectively prevent impurities from entering the boiler, which could lead to a decrease in heat exchange efficiency and safety hazards.

[0019] Please see Figure 1-6This utility model provides a technical solution: an environmentally friendly boiler water supply device, including a boiler inlet pipe 2 and a fixing frame 3 installed on a boiler 1. A water tank 4 and a filter assembly are installed on the upper end of the fixing frame 3. The filter assembly is set on the water tank 4 and includes a filter box 5. The filter box 5 is fixedly connected to the upper left side of the water tank 4. A filter frame 18 is set inside the filter box 5. A water inlet pipe 12 is set inside the filter box 5. A connecting cover 13 is fixedly connected to the lower end of the water inlet pipe 12. A nozzle 14 is rotatably connected to the inner side of the connecting cover 13. Multiple first drainage channels 15 are opened near the axis of the nozzle 14. Multiple curved second drainage channels 16 are opened near the edge of the nozzle 14. The water outlet of the second drainage channel 16 is inclined downward and forms an angle with the tangent of the edge of the nozzle 14.

[0020] The upper end of the filter box 5 is fixedly connected to the filter box cover 11 by bolts, and the water inlet pipe 12 is fixedly connected to the filter box cover 11.

[0021] A flow guide frame 17 is fixedly connected to the inner wall of the filter box 5, and a filter frame 18 is set inside the flow guide frame 17. The flow guide frame 17 and the filter frame 18 are fixed together by bolts.

[0022] A sealing gasket 19 is provided between the flow guide frame 17 and the filter frame 18.

[0023] The lower end of the fixing frame 3 is arc-shaped and fits against the surface of the boiler 1.

[0024] A water pump 6 is fixedly connected to the upper end of the water tank 4, and a first water pipe 7 is fixedly connected to the water inlet end of the water pump 6.

[0025] The first water pipe 7 extends into the interior of the water tank 4.

[0026] An activated carbon filter box 8 is fixedly connected to the outlet end of the water pump 6, and a second water pipe 9 is fixedly connected to the end of the activated carbon filter box 8 away from the water pump 6.

[0027] The upper end of the boiler inlet pipe 2 is fixedly connected to a sealing flange 10 by bolts.

[0028] The second water pipe 9 is fixed to the sealing flange 10, and the second water pipe 9 extends into the interior of the boiler 1.

[0029] When using the device, an external water pump injects the water to be treated into the filter box 5 through the inlet pipe 12. The water flows through the connecting cover 13 at the lower end of the inlet pipe 12 and enters the nozzle 14. Since the second drainage channel 16 at the edge of the nozzle 14 is curved and the outlet end is tilted downward and forms an angle with the tangential direction of the nozzle edge, the water flow generates a tangential reaction force when it is sprayed out, which drives the nozzle 14 to rotate autonomously inside the connecting cover 13.

[0030] The nozzle 14 sprays a straight stream of water from the first drainage channel 15 near the axis, which vertically impacts the filter frame 18 below, thus concentrating the rinsing of the filter screen surface and preventing impurities from adhering and accumulating.

[0031] The second drainage channel 16, which rotates with the nozzle 14, sprays out a ring-shaped diffusion water flow, covering the edge area of ​​the filter frame 18, achieving thorough rinsing; the filter frame 18 intercepts solid impurities such as mud, sand, and rust in the water through its mesh, completing the first-stage filtration.

[0032] The filtered water flows into the water tank 4; the sealing gasket 19 between the guide frame 17 and the filter frame 18 ensures that the water flow is leak-free and all water passes through the filter frame 18; the filter box cover 11 is fixed with bolts to ensure the airtightness of the filter box 5 and prevent impurities from being mixed in again.

[0033] Start the water pump 6 at the top of the water tank 4 to draw water that has passed the first stage of filtration from the water tank through the first water pipe 7, pressurize it and send it to the activated carbon filter box 8; the activated carbon filter box 8 uses the adsorption properties of activated carbon to remove odors, organic pollutants and fine suspended particles from the water, and complete the second stage of deep filtration.

[0034] After secondary filtration, the clean water enters the boiler inlet pipe 2 through the second water pipe 9 and the sealing flange 10, and is finally injected into the boiler 1. The sealing flange 10 ensures the sealing of the pipe connection, avoids water leakage and loss, and ensures the stability and safety of the boiler water supply.

[0035] The lower end of the mounting bracket 3 is arc-shaped and fits tightly against the surface of the boiler 1, providing stable support for the water tank 4, filter components, etc., and preventing vibration from affecting the filtration effect during operation.

[0036] The filter box cover 11 and filter frame 18 are both fixed with bolts, which can be easily disassembled, making it convenient to regularly clean the impurities inside the filter box 5 or replace the filter media of the filter frame 18 and activated carbon filter box 8, ensuring long-term filtration efficiency.

[0037] Furthermore, the water outlet of the curved second drainage channel 16 at the edge of the nozzle 14 is at an angle to the tangent. When the water is sprayed out, the reaction force drives the nozzle to rotate autonomously. Combined with the direct water flow from the first drainage channel 15 in the middle, it forms an all-round, dead-angle-free rinsing effect. This design can continuously clean the impurities on the surface of the filter frame 18, avoid the clogging problem caused by the accumulation of impurities in traditional fixed filters, maintain a stable water flow rate, and ensure stable water supply pressure.

[0038] The primary filtration system intercepts solid impurities such as silt and rust through the filter frame 18, while the secondary filtration system adsorbs odors, organic pollutants, and fine particles through the activated carbon filter box 8. The two-stage filtration works synergistically to significantly improve water purification and effectively prevent impurities from entering the boiler, which could lead to a decrease in heat exchange efficiency and safety hazards.
