Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for cleaning boiler observation holes, and in particular to a spray cleaning device for boiler observation holes. Background Technology

[0002] A viewing plate 3 is typically installed at the boiler observation port via a steel pipe 4. The viewing plate 3 is connected to the opening of the steel pipe 4 via an outer cover 1 and a gasket 2. A manual cantilever 7 is rotatably fitted onto the steel pipe 4. A circular baffle 14 for sealing the steel pipe 4 is fixedly connected to the end of the manual cantilever 7 located on the inner side of the steel pipe 4. A handle 15 is fixedly connected to the end of the manual cantilever 7 located on the outer side of the steel pipe 4. Rotating the manual cantilever 7 allows the circular baffle 14 to switch between a vertical and a horizontal state. When the circular baffle 14 is in a vertical state, it is perpendicular to the axis of the steel pipe 4, and it can seal the steel pipe 4 and also protect the viewing plate 3. When the circular baffle 14 is in a horizontal state, it is parallel to the axis of the steel pipe 4, and the steel pipe 4 is in a transparent state, making it easy for operators to observe the internal conditions of the boiler. Under normal circumstances, due to gravity, the handle 15 connected to the manual cantilever 7 is in a natural vertical downward state. At this time, the circular baffle 14 is in a vertical state and blocks the steel pipe 4.

[0003] The viewing plate 3 is made of high-temperature resistant material. Operators can directly monitor the combustion state inside the furnace by looking through the viewing plate 3 and steel pipe 4. The observation port channel provides a clear view of the flame pattern, fuel distribution, ash accumulation, and ash discharge port status, which is crucial for ensuring safe boiler operation and production efficiency. However, during long-term boiler operation, the inner surface of the viewing plate 3 is easily contaminated by soot, coke, and oil, causing it to become blurred. This severely affects the operator's real-time judgment of the furnace conditions, thus threatening equipment safety. Traditional cleaning methods mainly rely on manual operation, requiring workers to use physical wiping or simple washing tools to clean the boiler while it is shut down. This is costly, time-consuming, labor-intensive, and inconvenient. Utility Model Content

[0004] To overcome the technical shortcomings of existing manual cleaning of viewing plates, which is costly, time-consuming, labor-intensive, and inconvenient, this utility model provides a spray cleaning device for boiler viewing holes.

[0005] This utility model provides a spray cleaning device for boiler observation holes, including a water pump, a fan, a cleaning liquid tank, and a spray interface. The spray interface includes a funnel-shaped cylinder with a baffle fixedly connected to the large opening of the funnel-shaped cylinder. The baffle has multiple spray holes. A water inlet pipe and an air inlet pipe are sealed and connected to the small opening of the funnel-shaped cylinder. The other end of the water inlet pipe is connected to the cleaning liquid tank, and the other end of the air inlet pipe is connected to the fan. The water pump is connected to the water inlet pipe. The cleaning liquid tank contains cleaning liquid. The spray interface and the water inlet pipe and air inlet pipe are matched with an inlet and outlet located on the side wall of the boiler. The bottom of the steel pipe on which the viewing plate is installed at the observation hole has a drain and exhaust port that matches the spray cleaning device.

[0006] When cleaning the inside of the viewing plate, the entire assembly, including the spray nozzle, water inlet pipe, and air inlet pipe, extends from the inlet / outlet on the boiler side wall to the observation hole. The spray nozzle is then moved to align with the opening of the steel pipe (no connection is required, just contact). The water pump, fan, and cleaning fluid tank are located outside the boiler. Power is supplied to the water pump and fan. First, the water pump pressurizes the cleaning agent in the cleaning fluid tank and sprays it onto the steel pipe and viewing plate. The cleaning agent removes soot, slag, and oil from the inside of the viewing plate. Then, the water pump is turned off and the fan is turned on. Air passes through the air inlet pipe, spray nozzle, and spray holes, and is blown into the steel pipe, drying the moisture on the inside of the viewing plate. The air and cleaning fluid are promptly discharged from the drain and exhaust ports at the bottom of the steel pipe. When cleaning the viewing plate using the spray cleaning device described in this invention, the boiler does not need to be shut down. The viewing plate can be cleaned while the boiler is burning through the inlet / outlet on the boiler side wall. It is convenient to operate, saves time and effort, and reduces costs.

[0007] Preferably, the water pump is fixed to the top of the cleaning fluid tank. This ensures that the water pump can be moved simultaneously when the cleaning tank is moved, improving the overall ease of use of the device.

[0008] Preferably, the device also includes a lifting platform, with the bottom of the cleaning fluid tank flush with the bottom of the blower, for fixed connection to the top of the lifting platform. The lifting platform allows the entire spray cleaning device to be moved up, down, left, and right, so that the spray interface entering the boiler from the inlet / outlet on the boiler side wall can be aligned with the observation hole. The lifting platform ensures the stability of the entire device when moving it, saving time and effort. Precise positioning is achieved through the lifting platform, avoiding manual approach to the high-temperature observation hole, thus reducing the accident rate; the standardized interface design adapts to various boiler observation hole types, improving installation and commissioning efficiency.

[0009] Preferably, the spray holes are evenly distributed on the baffle, or the spray holes are arranged in a divergent pattern on the baffle. This arrangement is to ensure more uniform water or air intake.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following technical effects: the directional spray mode of the spray interface can achieve periodic rinsing of the fluoroscopic film, which greatly improves the cleaning efficiency compared with the traditional manual method, saves time and labor, saves costs, and has a high dust removal rate and low residue of coke on the surface of the high-temperature resistant fluoroscopic film, significantly improving the observation clarity of the fluoroscopic film; the fan can achieve rapid drying function, reduce the corrosion of the high-temperature resistant fluoroscopic film by the residual cleaning fluid, and ensure the service life of the fluoroscopic film.

[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] In one embodiment, such as Figure 1 As shown, a spray cleaning device for boiler observation holes is disclosed, including a water pump 12, a fan 10, a cleaning liquid tank 13, and a spray interface 8. The spray interface 8 includes a trumpet-shaped cylinder, with a baffle 6 fixedly connected to the large opening of the trumpet-shaped cylinder. The baffle 6 has multiple spray holes 801. A water inlet pipe 11 and an air inlet pipe 9 are sealed and connected to the small opening of the trumpet-shaped cylinder. The other end of the water inlet pipe 11 is connected to the cleaning liquid tank 13, and the other end of the air inlet pipe 9 is connected to the fan 10. The water pump 12 is connected to the pipeline of the water inlet pipe 11. The cleaning liquid tank 13 contains cleaning liquid. The spray interface 8 and the water inlet pipe 11 and air inlet pipe 9 are matched with an inlet and outlet located on the side wall of the boiler. The bottom of the steel pipe 4, on which the viewing plate 3 is installed at the observation hole, has a drain and exhaust port 5 that matches the spray cleaning device.

[0023] When it is necessary to clean the inside of the viewing plate 3, extend the entire assembly of the spray interface 8, water inlet pipe 11, and air inlet pipe 9 from the inlet / outlet on the side wall of the boiler to the observation hole, and move the spray interface 8 to align it with the opening of the steel pipe 4 (no connection is required, just contact is sufficient). The water pump 12, blower 10, and cleaning fluid tank 13 are located outside the boiler. Turn on the power to the water pump 12 and blower 10. First, the water pump 12 pressurizes the cleaning agent in the cleaning fluid tank 13 and sprays it onto the steel pipe 4 and the viewing plate 3. The cleaning agent can remove the soot, coke residue, and oil stains on the inside of the viewing plate 3. Then, turn off the water pump 12 and turn on the blower 10.

Moreover, it is convenient to operate, saves time and effort, and saves costs.

[0024] Based on the above embodiments, in a preferred embodiment, the water pump 12 is fixed to the top of the cleaning fluid tank 13. This ensures that the water pump 12 can be moved simultaneously when the cleaning fluid tank 13 is moved, improving the overall ease of use of the device.

[0025] Based on the above embodiments, in a preferred embodiment, a lifting platform is further included. The bottom of the cleaning fluid tank 13 is flush with the bottom of the blower 10, and is fixedly connected to the top of the lifting platform. The lifting platform allows the spray cleaning device of this invention to be moved up and down, and left and right, so that the spray interface 8, which enters the boiler from the inlet / outlet on the boiler side wall, can be aligned with the observation hole. The lifting platform ensures the stability of the entire device when moving the spray cleaning device of this invention, and saves time and effort. The lifting platform enables precise positioning, avoiding manual approach to the high-temperature observation hole, thus reducing the accident rate; the standardized interface design adapts to various types of observation holes in boilers, improving installation and commissioning efficiency.

[0026] Based on the above embodiments, in a preferred embodiment, the spray holes 801 are evenly distributed on the baffle 6, or the spray holes 801 are arranged in a divergent pattern on the baffle 6. This arrangement is for more uniform water or air intake.
