Description

Technical Field

[0001] The invention belongs to the technical field of boiler equipment, and in particular relates to a natural gas boiler cleaning device. Background Art

[0002] A natural gas boiler is a device that uses natural gas as fuel to generate hot water or steam. It is widely used in residential heating, commercial buildings, industrial production and other fields. Natural gas is mixed with air in the combustion chamber and ignited to produce a high-temperature flame. The heat generated by the combustion is transferred to the water through the heat exchanger, which increases the water temperature or turns it into steam. The heated water or steam is transported through pipes to places where heating is required, such as radiators or hot water supply systems. The exhaust gas after combustion is discharged outdoors through chimneys or other exhaust systems.

[0003] Over time, scale and sediment will accumulate inside the boiler, which will form an insulating layer that hinders the effective transfer of heat. At the same time, the exhaust gas after natural gas combustion needs to be filtered before it can be discharged outdoors, and the filtration system needs to be cleaned regularly to ensure the normal discharge of exhaust gas. Traditional natural gas boilers usually require professionals to conduct comprehensive inspections and cleaning of the boiler after a period of use, which not only requires high costs, but also requires downtime and delays in production. However, if the boiler is not cleaned regularly, the internal pipes will be blocked, and serious production accidents are likely to occur. Summary of the invention

The tempering chamber 15 is provided at a side of the furnace body 1 close to the burner 6, and the smoke exhaust chamber 16 is provided at a side of the furnace body 1 close to the smoke exhaust port 41. The tempering chamber 15 is communicated with the furnace 13, and the smoke exhaust chamber 16 is communicated with the smoke exhaust port 41. A plurality of heat conducting pipes 14 are distributed in an array around the furnace 13, and the tempering chamber 15 is communicated with the smoke exhaust chamber 16 through the heat conducting pipes 14. A water inlet 11 and a steam outlet 12 are provided on the top of the furnace body 1; The electric push rod 7 can drive the cleaning mechanism 2 to slide horizontally in the furnace body 1 .

[0030] In this embodiment, water is introduced into the furnace body 1 through the water inlet 11, and the water is between the furnace 13 and the inner wall of the furnace body 1. Then the burner 6 introduces natural gas into the furnace 13 for combustion. The flue gas generated by the combustion first enters the tempering chamber 15, then enters the exhaust chamber 16 through the heat pipe 14, and is finally discharged through the exhaust port 41. The heat generated by the combustion of natural gas heats the water in the furnace body 1. At the same time, the high-temperature flue gas generated by the combustion of natural gas will also heat the water in the furnace body 1 during the process of passing to the exhaust chamber 16. The water vapor generated by the heated water is discharged through the steam outlet 12. When the furnace body 1 is heating the water, starting the electric push rod 7 can drive the cleaning mechanism 2 to slide horizontally in the furnace body 1, clean the surfaces of the inner wall of the furnace body 1, the outer wall of the furnace 13 and the outer wall of the heat pipe 14 that are in contact with water, remove scale, and delay the accumulation of scale, thereby reducing the frequency of boiler shutdown for comprehensive inspection and cleaning, and effectively improving production efficiency.

[0031] like Figure 2 - Figure 6 As shown, a filter cartridge 4 is fixedly connected to the inner side of the smoke exhaust port 41, and the filter cartridge 4 is fixedly arranged in the smoke exhaust chamber 16; A filter cartridge cleaning component 3 is rotatably connected in the smoke exhaust chamber 16.

One end of the guide elbow 141 is fixedly connected to the heat conducting pipe 14 , and the other end of the guide elbow 141 opens toward the fan blades 31 .

[0032] In this embodiment, the exhaust gas generated by the combustion of natural gas entering the smoke exhaust chamber 16 needs to pass through the filter cartridge 4 before being discharged through the smoke exhaust port 41. The filter cartridge 4 is filtered for a long time, and dust will accumulate on the surface of the filter cartridge 4, affecting the passability of the filter cartridge 4. The exhaust gas generated by the combustion of natural gas entering the smoke exhaust chamber 16 is blown toward the fan blades 31 through the guide bend 141, thereby driving the filter cartridge cleaning component 3 to rotate, and the dust-push plate 32 can move the filter cartridge 4, and the dust filtered and adsorbed on the filter cartridge 4 is pushed off by the dust-push plate 32, thereby reducing the dust accumulated on the filter cartridge 4, keeping the exhaust of the combustion exhaust gas unobstructed, and increasing the service life of the filter cartridge 4.

[0033] like Figure 2 as well as Figure 7 - Fig.14 As shown, the cleaning mechanism 2 includes a base plate 21, a transmission ring 22, a first cleaning ring 23 and a second cleaning ring 24.

There are multiple first cleaning rings 23, and the first cleaning rings 23 are sleeved on the heat pipe 14. The position and number of the first cleaning rings 23 correspond to the heat pipe 14 one by one. The second cleaning rings 24 are sleeved on the furnace 13. A helical gear ring 221 is disposed on the outer side of the transmission ring 22, a transmission gear ring 222 is disposed on the inner side of the transmission ring 22, a first driven gear ring 233 is disposed on the outer side of the first cleaning ring 23, and a second driven gear ring 243 is disposed on the outer side of the second cleaning ring 24. One side of the first driven gear ring 233 is meshed with the transmission gear ring 222, and the other side of the first driven gear ring 233 is meshed with the second driven gear ring 243; A first brush 231 is fixedly disposed at one end of the inner side of the first cleaning ring 23, a first scraper 232 is fixedly disposed at the other end of the inner side of the first cleaning ring 23, a second brush 241 is fixedly disposed at one end of the inner side of the second cleaning ring 24, and a second scraper 242 is fixedly disposed at the other end of the inner side of the second cleaning ring 24; A transmission assembly 5 is provided at the top of the furnace body 1. The transmission assembly 5 includes a rack 52 and a transmission rod 51. The rack 52 is fixedly connected to the top of the furnace body 1. The transmission rod 51 is rotatably connected to the base plate 21. One end of the transmission rod 51 is fixedly connected to a transmission gear 512. The other end of the transmission rod 51 is fixedly connected to a bevel gear 511. The transmission gear 512 meshes with the rack 52. The bevel gear 511 meshes with the bevel gear ring 221. The top of the electric push rod 7 is fixedly connected to the base plate 21. A bracket 211 and an escape groove 213 are provided on the top of the base plate 21 . The transmission rod 51 is rotatably connected to the bracket 211 . The escape groove 213 allows the rack 52 to pass through. A side scraper 212 is provided on the side of the base plate 21 .

[0034] In this embodiment, when the electric push rod 7 drives the substrate 21 to slide horizontally in the furnace body 1, the rack 52 drives the transmission rod 51 to rotate, the rotation of the transmission rod 51 drives the bevel gear 511 to rotate, the rotation of the bevel gear 511 drives the transmission ring 22 to rotate, thereby driving the first cleaning ring 23 and the second cleaning ring 24 to rotate; When the first cleaning ring 23 slides horizontally with the cleaning mechanism 2, the first scraper 232 can scrape the outer wall of the heat conducting tube 14, and when the first cleaning ring 23 rotates, the first brush 231 can clean the outer wall of the heat conducting tube 14, and when the second cleaning ring 24 slides horizontally with the cleaning mechanism 2, the second scraper 242 can scrape the outer wall of the furnace 13, and when the second cleaning ring 24 rotates, the second brush 241 can clean the outer wall of the furnace 13; When the substrate 21 slides horizontally in the furnace body 1, the side scraper 212 can scrape the inner wall of the furnace body 1, cooperate with the first cleaning ring 23 to clean the outer wall of the heat pipe 14, and the second cleaning ring 24 to clean the outer wall of the furnace chamber 13, so that all surfaces in contact with water in the furnace body 1 can be fully cleaned.

[0035] like Figure 2 as well as Figure 7 - Fig.14 As shown, both the base plate 21 and the second cleaning ring 24 are provided with through grooves.

[0036] In this embodiment, the provision of the through groove effectively reduces the resistance of the cleaning mechanism 2 in the water when the cleaning mechanism 2 slides horizontally in the furnace body 1, thereby reducing energy waste. At the same time, when the cleaning mechanism 2 slides horizontally in the furnace body 1 to clean the furnace body 1, the cleaning mechanism 2 can disturb the water in the furnace body 1, and a descaling agent can be added to the water while the cleaning mechanism 2 is cleaning. The disturbance of the water body by the cleaning mechanism 2 can accelerate the diffusion of the descaling agent in the water body, thereby effectively improving the cleaning efficiency.

[0037] Working principle: During operation, water is introduced into the furnace body 1 through the water inlet 11, and the water is between the furnace 13 and the inner wall of the furnace body 1. Then the burner 6 introduces natural gas into the furnace 13 for combustion. The smoke generated by the combustion first enters the tempering chamber 15, and then enters the exhaust chamber 16 through the heat pipe 14. The heat generated by the combustion of natural gas heats the water in the furnace body 1. At the same time, the high-temperature smoke generated by the combustion of natural gas will heat the water in the furnace body 1 during the process of entering the exhaust chamber 16. The water vapor generated by the heated water is discharged through the steam outlet 12. The exhaust gas generated by the combustion of natural gas entering the smoke exhaust chamber 16 needs to pass through the filter cartridge 4 before being discharged through the smoke exhaust port 41. The filter cartridge 4 is filtered for a long time, and dust will accumulate on the surface of the filter cartridge 4, affecting the passability of the filter cartridge 4. The exhaust gas generated by the combustion of natural gas entering the smoke exhaust chamber 16 is blown toward the fan blades 31 through the guide elbow 141, thereby driving the filter cartridge cleaning component 3 to rotate, and the dust-push plate 32 can poke the filter cartridge 4, and the dust filtered and adsorbed on the filter cartridge 4 is pushed off by the dust-push plate 32, thereby reducing the dust accumulated on the filter cartridge 4, maintaining the unobstructed exhaust of the combustion exhaust gas, and increasing the service life of the filter cartridge 4. When the furnace body 1 needs to be cleaned during the operation of the boiler, a descaling agent is added to the water, and then the electric push rod 7 is started. The electric push rod 7 drives the cleaning mechanism 2 to slide back and forth horizontally in the furnace body 1. The disturbance of the water body by the cleaning mechanism 2 can accelerate the diffusion of the descaling agent in the water body, effectively improving the cleaning efficiency; At this time, the rack 52 drives the transmission rod 51 to rotate, the rotation of the transmission rod 51 drives the bevel gear 511 to rotate, the rotation of the bevel gear 511 drives the transmission ring 22 to rotate, thereby driving the first cleaning ring 23 and the second cleaning ring 24 to rotate; When the first cleaning ring 23 slides horizontally with the cleaning mechanism 2, the first scraper 232 can scrape the outer wall of the heat conducting tube 14, and when the first cleaning ring 23 rotates, the first brush 231 can clean the outer wall of the heat conducting tube 14, and when the second cleaning ring 24 slides horizontally with the cleaning mechanism 2, the second scraper 242 can scrape the outer wall of the furnace 13, and when the second cleaning ring 24 rotates, the second brush 241 can clean the outer wall of the furnace 13; When the substrate 21 slides horizontally in the furnace body 1, the side scraper 212 can scrape the inner wall of the furnace body 1, cooperate with the first cleaning ring 23 to clean the outer wall of the heat pipe 14, and the second cleaning ring 24 to clean the outer wall of the furnace 13, so as to achieve comprehensive cleaning of the surfaces in contact with water in the furnace body 1, effectively remove scale, and delay the accumulation of scale, thereby reducing the frequency of boiler shutdown for comprehensive inspection and cleaning, and effectively improving production efficiency.
