Description

Technical Field

[0001] This utility model relates to the field of boiler cleaning technology, specifically to a steam boiler with a cleaning structure. Background Technology

[0002] A steam boiler is a device specifically designed to heat water and convert it into steam. It is widely used in power generation, heating, and industrial production. Its core function is to heat water into steam by burning fuel or other energy sources (such as electricity) at high temperatures, providing heat or power for various applications.

[0003] The patent document with announcement number CN219140752U describes a steam boiler with an internal wall cleaning structure. The described solution cleans the stains on the inner wall of the steam boiler by rotating a cleaning brush. By adjusting the position of the cleaning brush, the entire inner wall of the steam boiler can be cleaned, avoiding the need to disassemble the steam boiler and allow manual entry for cleaning. This makes the cleaning work simple and convenient, reduces the workload of workers, and further improves the cleaning effect by spraying a descaling agent on the inner wall of the boiler. The cleaned stains are easy to collect and discharge.

[0004] While the above-mentioned technology can spray descaling agent onto the inner wall of the boiler, it cannot change the spraying direction. Because the spraying direction is fixed, the descaling agent may not be able to evenly cover all areas of the inner wall of the boiler, and scale in some areas may not be removed, affecting the boiler's heat exchange efficiency. It may also lead to incomplete cleaning and waste of descaling agent. Utility Model Content

[0008] Boiler body;

[0009] A sealing sleeve; the sealing sleeve is located at one end of the boiler body;

[0010] It also includes a cleaning assembly for cleaning the inside of the boiler body. The cleaning assembly includes a hollow tube that passes through the inside of a sealing sleeve. One end of the hollow tube is equipped with a water spray head. A rotary joint is provided on the end of the hollow tube away from the boiler body. The other end of the rotary joint is connected to a water pipe. A moving assembly for moving the hollow tube is provided on the top of the boiler body.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-3 As shown, a steam boiler with a cleaning structure includes: a boiler body 100, a sealing sleeve 200, and a cleaning assembly. The sealing sleeve 200 is located at one end of the boiler body 100. The cleaning assembly includes a hollow tube 301, which passes through the sealing sleeve 200. A water spray head 302 is provided inside one end of the hollow tube 301. A rotary joint 303 is provided at the end of the hollow tube 301 away from the boiler body 100. A water pipe 304 is connected to the other end of the rotary joint 303. A moving assembly for moving the hollow tube 301 is provided on the top of the boiler body 100. A cleaning assembly for cleaning the inner wall of the boiler body 100 is provided at one end of the hollow tube 301. Cleaning liquid is connected to the water pipe 304, and then the cleaning liquid is delivered into the hollow tube 301 through the rotary joint 303. The cleaning liquid is then discharged through the water spray head 302.

[0028] In one embodiment, such as Figure 1 and Figure 2As shown, the moving component includes a support frame 401, which is located on the top of the boiler body 100. A slider 402 is slidably connected inside the support frame 401. A first motor 403 is provided at one end of the support frame 401. A threaded rod 404 is provided at the output end of the first motor 403. The threaded rod 404 is rotatably connected inside the support frame 401 and threadedly connected inside the slider 402. An L-shaped block 405 is fixedly connected to the upper part of the slider 402. The other end of the L-shaped block 405 is connected to the top of the rotary joint 303. A rotating component for rotating the hollow tube 301 is provided on the L-shaped block 405. By starting the first motor 403, it drives the threaded rod 404 to rotate, thereby driving the slider 402 to move inside the support frame 401. Subsequently, under the action of the L-shaped block 405, the movement of the slider 402 drives the rotary joint 303 to move, thereby driving the hollow tube 301 to move.

[0029] In one embodiment, such as Figure 2 and Figure 3 As shown, the cleaning assembly includes a support rod 501, which is fixedly connected to one end of the hollow tube 301. A slide rod 502 is slidably connected inside the support rod 501. A spring 503 is provided between the support rod 501 and the slide rod 502. A scraper 504 is provided on the end of the slide rod 502 away from the support rod 501. The scraper 504 contacts the inner wall of the boiler body 100, causing it to squeeze the slide rod 502. Then, under the action of the spring 503, it forms a counterforce against the slide rod 502, thereby allowing the scraper 504 to fit against the inner wall of the boiler body 100.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the rotating assembly includes a second motor 601, which is mounted on one end of the L-shaped block 405. The output end of the second motor 601 is provided with a first rotating gear 602, which meshes with a second rotating gear 603. The interior of the second rotating gear 603 is fixedly connected to the outer surface of the hollow tube 301. By starting the second motor 601, it drives the first rotating gear 602 to rotate, thereby driving the second rotating gear 603 to rotate, and thus driving the hollow tube 301 to rotate.

[0031] In one embodiment, such as Figure 2 As shown, the scraper 504 is in close contact with the inner wall of the boiler body 100, which facilitates the scraping of dirt from the inner wall of the boiler body 100.

[0032] In one embodiment, such as Figure 2As shown, a discharge pipe is provided on the end of the boiler body 100 away from the sealing sleeve 200, and a valve is provided on the discharge pipe to facilitate the discharge of dirt.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the sealing sleeve 200 has a sealing ring inside to increase the sealing performance.

[0034] In one embodiment, such as Figure 2 As shown, the spray head 302 is equipped with a one-way valve to prevent liquid or foreign objects from entering the spray head 302 when it is not in use.

[0035] The above embodiments disclose a steam boiler with a cleaning structure. When cleaning the interior of the boiler body 100 is required, cleaning fluid can be connected to a water pipe 304, and then the cleaning fluid is delivered into the hollow tube 301 through a rotary joint 303. The cleaning fluid is then discharged through a spray nozzle 302, thereby cleaning the interior of the boiler body 100. Subsequently, a scraper 504 contacts the inner wall of the boiler body 100, causing it to press against a slide rod 502. Under the action of a spring 503, a counterforce is generated on the slide rod 502, allowing the scraper 504 to adhere to the inner wall of the boiler body 100. Then, the first motor 403 is activated. This causes the threaded rod 404 to rotate, which in turn causes the slider 402 to move inside the support frame 401. Subsequently, under the action of the L-shaped block 405, the movement of the slider 402 causes the rotary joint 303 to move, which in turn causes the hollow tube 301 to move, which in turn causes the scraper 504 to move on the inner wall of the boiler body 100 for scraping and cleaning. Alternatively, the second motor 601 can be started to drive the first rotating gear 602 to rotate, which in turn drives the second rotating gear 603 to rotate, which in turn drives the hollow tube 301 to rotate, thus enabling it to clean the inner wall of the boiler body 100 from different directions.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
