Detailed Embodiment

[0026] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, the orientation terms used generally refer to the orientation of the relevant components in the actual use state. "Inside and outside" can refer to the inside and outside of the contour of the corresponding component or its inside or outside the environment in which it is located according to the specific context. In addition, when the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another, and do not have sequentiality and importance.

[0028] As Figures 1 to 3 shown, the present disclosure provides a boiler, including a boiler body 100, a pH detection sensor 200, a cleaning component 300, and a water tank 400. The pH detection sensor 200 is used to detect the pH of the liquid in the boiler body 100; the cleaning component 300 is arranged in the boiler body 100 and is used to scrape the deposits on the inner wall of the boiler body 100; the water tank 400 is provided with a cleaning liquid and a neutralizing liquid that can enter the boiler body 100. The cleaning liquid is used to decompose the deposits on the inner wall of the boiler body 100, and the neutralizing liquid is used to neutralize the cleaning liquid.

[0029] Through the above technical solution, the cleaning liquid can decompose the sediment on the inner wall of the boiler body 100, making it easier for the sediment to detach from the inner wall of the boiler body 100. Then, the cleaning assembly 300 is used to scrape the sediment on the inner wall of the boiler body 100, ensuring the cleaning effect of the cleaning assembly 300 on the boiler. After cleaning the boiler body 100, there will still be residual cleaning liquid in the liquid in the boiler body 100, making the liquid in the boiler body 100 acidic or alkaline. If it is discharged without treatment, it will cause environmental pollution. The pH sensor 200 can detect the pH of the liquid in the boiler body 100, and the liquid in the boiler body 100 is neutralized by the neutralizing liquid. When the pH of the liquid in the boiler body 100 detected by the pH sensor 200 is neutral, the liquid is then discharged to avoid environmental pollution.

[0030] Generally speaking, taking hot water boilers and steam boilers as examples, the sediment on the inner wall of the boiler body 100 is usually alkaline. At this time, the cleaning liquid usually selected is acidic. The effect of the cleaning liquid decomposing the sediment on the inner wall of the boiler body 100 is ensured by acid-base neutralization. At the same time, in order to further ensure the decomposition of the sediment on the inner wall of the boiler body 100, the cleaning liquid is usually added in excess to the boiler body 100 so that the cleaning liquid can fully react with the sediment. This will result in the residual cleaning liquid in the boiler body 100, making the liquid in the boiler body 100 acidic. In some other boilers, the cleaning liquid is usually selected to be alkaline. At this time, the neutralizing liquid should be selected to be acidic.

[0031] Continuing to take hot water boilers and steam boilers as examples, generally speaking, when hot water boilers and steam boilers are in use, the temperature of the liquid in the boiler body 100 is relatively high. Therefore, the pH sensor 200 needs to be heat-resistant to prevent the pH sensor 200 from being damaged by heat during boiler use. In some embodiments, the detection end of the pH sensor 200 can adopt a glass composite electrode, and the glass composite electrode can withstand temperatures up to 130°C or even higher. In some other embodiments, the pH sensor 200 can also be a solid electrolyte sensor and an optical fiber sensor. The solid electrolyte sensor uses a solid electrolyte, ensuring its heat resistance and chemical corrosion resistance. The optical fiber sensor measures the pH value by using the characteristics of light and has no electronic components, so it can withstand extreme temperatures and electromagnetic interference.

[0032] A liquid inlet 401 may be provided on the water tank 400. The boiler may further include a first pipeline 500, with two ends respectively communicating with the inside of the water tank 400 and the inside of the boiler body 100. A pump body is provided on the first pipeline 500 for conveying the liquid in the water tank 400 into the boiler body 100. The cleaning liquid and the neutralizing liquid may enter the water tank 400 from the liquid inlet 401 on the water tank 400. The first pipeline 500 can connect the boiler body 100 and the water tank 400 to enable the cleaning liquid and the neutralizing liquid to communicate with the boiler body 100. The pump body is used to provide power so that the cleaning liquid and the neutralizing liquid can enter the boiler body 100. When cleaning the boiler body 100, the cleaning liquid can be first injected into the water tank 400, and after the body is cleaned, the neutralizing liquid can be injected into the water tank 400.

[0033] The cleaning assembly 300 may further include a spray pipe 301 rotatably arranged inside the boiler body 100. A plurality of nozzles 302 are provided on the spray pipe 301, and the spray pipe 301 communicates with the first pipeline 500. The nozzles 302 can increase the coverage range of the cleaning liquid and further ensure the cleaning effect of the cleaning liquid. At the same time, the nozzles 302 can increase the coverage range of the neutralizing liquid so that the neutralizing liquid can neutralize the liquid attached to the inner wall surface of the boiler body 100 and ensure the neutralizing effect of the neutralizing liquid.

[0034] The cleaning assembly 300 may further include a drive shaft 303 rotatably fixed on the boiler body 100. The boiler further includes a drive motor 600 for driving the drive shaft 303 to rotate. The spray pipe 301 is connected to the drive shaft 303 so that the drive shaft 303 drives the spray pipe 301 to rotate. The drive motor 600 drives the spray pipe 301 to rotate through the drive shaft 303, and the spray pipe 301 drives the nozzles 302 to rotate, and the range that the nozzles 302 can cover is further increased. When the nozzles 302 spray the cleaning liquid, the cleaning liquid can be sprayed onto every sediment inside the boiler body 100. When the nozzles 302 spray the neutralizing liquid, the neutralizing liquid can neutralize the liquid attached to the inner wall surface of the boiler body 100 as much as possible. At the same time, the operator can remotely control the start and stop of the drive motor 600, which is more convenient for the use of the cleaning assembly 300. The drive shaft 303 can be rotatably fixed on the boiler body 100 through bearings, and the output shaft of the drive motor 600 can be indirectly connected to the drive shaft 303 to drive the drive shaft 303. Refer to Figure 1 At this time, the output shaft of the drive motor 600 and the drive shaft 303 are connected by a belt. In some other embodiments, the output shaft of the drive motor 600 can also be connected to the drive shaft 303 by a chain. In the present disclosure, the connection manner between the drive motor 600 and the drive shaft 303 is not limited as long as it satisfies that the drive motor 600 can drive the drive shaft 303 to rotate. Continue to refer to Figure 1, the driving motor 600 can be fixed on the outer wall surface at the top of the boiler body 100, so that the driving shaft 303 can also be rotatably fixed at the top of the boiler body 100, and the liquid in the boiler body 100 will not leak out from the connection between the driving shaft 303 and the boiler body 100.

[0035] Referring to Figure 2 , in order to avoid interference with the transmission between the driving motor 600 and the driving shaft 303, the boiler may further include a protective cover 102, and the protective cover 102 covers both the driving motor 600 and the driving shaft 303 at the same time to protect the driving motor 600 and the driving shaft 303.

[0036] A channel 304 for liquid circulation may be provided in the driving shaft 303. One end of the first pipeline 500 is rotatably communicated with the channel 304, and the spray pipe 301 is communicated with the first pipeline 500 through the channel 304. In order to avoid the first pipeline 500 being wound when the driving shaft 303 drives the spray pipe 301 to rotate, one end of the first pipeline 500 can be rotatably communicated with the channel 304, and one end of the driving shaft 303 and one end of the first pipeline 500 can be connected to each other through a rotary joint to ensure that one end of the first pipeline 500 can be rotatably communicated with the channel 304. At the same time, the channel 304 is arranged in the driving shaft 303, so that no additional pipeline needs to be provided when the first pipeline 500 and the spray pipe 301 are connected, reasonably utilizing the space inside the driving shaft 303 and reducing the space occupied by the cleaning assembly 300.

[0037] The boiler body 100 can be configured in a cylindrical shape, the spray pipe 301 is coaxial with the boiler body 100, and the cleaning assembly 300 further includes a scraper 305 extending along the axis of the boiler body 100 in the same direction and connected to the spray pipe 301. An elastic contact member 306 for abutting against the inner wall surface of the boiler body 100 is provided on the surface of the scraper 305 facing the inner wall surface of the boiler body 100. The boiler body 100 can be configured in a cylindrical shape and the spray pipe 301 is coaxial with the boiler body 100. When the scraper 305 is connected to the spray pipe 301, the cleaning dead angle of the scraper 305 can be reduced, the cleaning efficiency of the scraper 305 and the cleanliness of the boiler body 100 can be improved. At the same time, the cooperation between the cleaning liquid sprayed by the nozzle 302 and the cleaning action of the scraper 305 further ensures the cleanliness of the boiler body 100. The close contact between the elastic contact member 306 and the inner wall of the boiler ensures that the scraper 305 can effectively remove the deposits and dirt on the inner wall surface during the movement, improving the cleaning efficiency. At the same time, the design of the elastic contact member 306 enables the scraper 305 to adapt to the possible slight unevenness of the inner wall surface of the boiler body 100, maintaining the balance of the contact pressure and reducing the scratches or damages caused by hard contact.

[0038] The cleaning assembly 300 may further include a connecting rod 307. The two ends of the connecting rod 307 are respectively connected to the spray pipe 301 and the scraper 305. The scraper 305 is connected to the spray pipe 301 through the connecting rod 307. As a bridge between the spray pipe 301 and the scraper 305, the connecting rod 307 can provide sufficient structural stability and mechanical strength to ensure that during the cleaning process, the scraper 305 and the spray pipe 301 can maintain the correct relative positions, avoiding displacement between the scraper 305 and the spray pipe 301 due to external forces. At the same time, the connecting rod 307 ensures the synchronous movement of the scraper 305 and the spray pipe 301, ensuring that while cleaning the boiler body 100, the scraper 305 can effectively remove the deposits on the inner wall of the boiler. This synchronous operation can greatly improve the cleaning efficiency and effect. The length of the connecting rod 307 can be adjusted according to the specific size and shape of the boiler body 100, enabling the cleaning assembly 300 to adapt to boilers of different sizes and shapes, increasing the flexibility and scope of operation.

[0039] A plurality of scrapers 305 may be arranged at intervals along the circumferential direction of the spray pipe 301. The plurality of scrapers 305 can repeatedly scrape the deposits on the inner wall of the boiler body 100, ensuring the cleaning effect on the inner wall surface of the boiler body 100 while significantly shortening the cleaning operation time and improving work efficiency.

[0040] An observation window 101 may be provided on the boiler body 100. Operators can observe the situation on the inner wall surface of the boiler body 100 through the observation window 101 to determine whether the deposits have been cleaned.

[0041] A second pipeline 700 for discharging liquid may also be provided on the boiler body 100, and a filter element is arranged in the second pipeline 700. In this way, the liquid in the boiler body 100 after being neutralized can be discharged from the second pipeline 700. During the discharging process, the deposits that have not been completely decomposed can be directly collected by the filter element and further processed to prevent environmental pollution by the deposits.

[0042] After the liquid in the boiler body 100 is discharged, clean water can be injected through the liquid inlet 401 on the water tank 400. The clean water enters the boiler body 100 through the first pipeline 500 and the spray pipe 301 to wash the boiler body 100. The scraper 305 can scrape the residues attached to the inner wall surface of the boiler body 100 to avoid the residues of the neutralizing liquid, cleaning liquid, and deposits in the boiler body 100.
