Description

Technical Field

[0001] This utility model relates to the field of boiler descaling technology, and in particular to a descaling device for heating boilers. Background Technology

[0002] During long-term operation, minerals such as calcium and magnesium in the water gradually deposit on the inner wall of the boiler and the surface of the heat exchange tubes, forming scale. Scale is a substance with extremely poor thermal conductivity, which reduces the boiler's thermal efficiency, increases energy consumption, and may even damage the boiler due to localized overheating, affecting the safe and stable operation of the heating system.

[0003] In practical use, existing descaling devices have some shortcomings:

[0004] Because the heat exchange tubes inside the boiler have small apertures and the scale adheres strongly to the inner wall of the tubes, traditional descaling methods that rely solely on water rinsing are insufficient to completely remove the scale, resulting in only average cleaning effectiveness.

[0005] Meanwhile, some devices lack a buffer structure during operation, which can easily cause damage to the boiler inner wall or heat exchange tubes due to rigid contact. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a descaling device for heating boilers, which overcomes the shortcomings of the existing technology and effectively solves the problems of mediocre cleaning effect and easy damage.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A descaling device for a heating boiler includes a housing. A servo motor is fixedly connected to the top of one outer wall of the housing by screws. The output shaft of the servo motor is fixedly connected to a drive gear via a coupling. A driven gear meshes on the outer wall of the drive gear, and a water inlet pipe is fixedly connected to the inner wall of the driven gear. A buffer assembly is provided on the outer wall of one end of the water inlet pipe, a water spray pipe is provided on the outer wall of one end of the buffer assembly, and a descaling assembly is provided on the outer wall of one end of the water spray pipe.

[0009] Preferably, the buffer assembly includes a connecting sleeve, a guide tube, and a spring, wherein the connecting sleeve is welded to the outer wall of one end of the water inlet pipe, the guide tube is slidably connected to the inner wall of one end of the connecting sleeve, and the spring is fixedly connected between the connecting sleeve and the guide tube.

[0010] Preferably, the spring is located inside the connecting sleeve, and the guide tube is welded to the outer wall of the other end of the water spray pipe.

[0011] Preferably, the descaling assembly includes a frame, a front scraper, a side scraper, and a nozzle. The frame is fixedly connected to the outer wall of one end of the water spray pipe via a flange. The front scraper is welded to the periphery of one side of the outer wall of the frame. The side scraper is welded to the periphery of the side wall of the frame. The nozzle is located at the center of one side of the outer wall of the frame.

[0012] Preferably, the outer wall of the other end of the water inlet pipe is rotatably connected to a water supply hose via a rotary joint.

[0013] Preferably, an installation sleeve is welded to the bottom of one side of the outer wall of the housing, and a handle is installed on the bottom outer wall of both the housing and the installation sleeve, and the water inlet pipe is installed through the inner wall of the installation sleeve.

[0014] Preferably, a switch is installed on one outer wall of the housing, and the switch is connected to the servo motor via a signal line.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The descaling device for heating boilers designed in this paper solves the problem of easy damage to boiler components during the descaling process by using a buffer component.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4 Example 1: A descaling device for a heating boiler includes a housing 1. A servo motor 2 is fixedly connected to the top of one side of the outer wall of the housing 1 by screws. The output shaft of the servo motor 2 is fixedly connected to a drive gear 3 via a coupling. A driven gear 4 meshes on the outer wall of the drive gear 3, and a water inlet pipe 12 is fixedly connected to the inner wall of the driven gear 4. A buffer assembly 5 is provided on the outer wall of one end of the water inlet pipe 12. The buffer assembly 5 includes a connecting sleeve 51, a guide tube 52, and a spring 53. The connecting sleeve 51 is welded to the outer wall of one end of the water inlet pipe 12. The guide tube 52 is slidably connected to the inner wall of one end of the connecting sleeve 51. The spring 53 is fixedly connected between the connecting sleeve 51 and the guide tube 52 and is located inside the connecting sleeve 51. The guide tube 52 is welded to the outer wall of the other end of the water spray pipe 6. A water supply hose 8 is rotatably connected to the outer wall of the other end of the water inlet pipe 12 via a rotary joint.

[0025] When the servo motor 2 starts, it drives the inlet pipe 12 to rotate via gear transmission, enabling multi-angle descaling of the descaling component 7. The water supply hose 8 can be flexibly bent for easy connection to an external water source, while the rotary joint ensures that the rotation of the inlet pipe 12 does not affect the water supply. When the descaling component 7 comes into contact with the boiler components, the guide tube 52 slides into the connecting sleeve 51, and the compression spring 53 generates elastic force to form a buffer, preventing hard contact damage to the components. The guide tube 52 is welded to the other end of the spray pipe 6 to ensure that the buffering force can be effectively transmitted to the descaling component 7.

[0026] In this embodiment, the front scraper 72 and the side scraper 73 in the descaling component 7 can directly contact the scale and remove stubborn scale through physical scraping. Combined with the high-pressure water flow sprayed from the nozzle 74, the scraped scale can be rinsed in time, which significantly improves the descaling efficiency. It is especially suitable for removing scale from areas with small pore diameters, such as heat exchange tubes.

[0027] Example 2: A descaling device for a heating boiler. A water spray pipe 6 is provided on the outer wall of one end of the buffer component 5, and a descaling component 7 is provided on the outer wall of one end of the water spray pipe 6. The descaling component 7 includes a frame 71, a front scraper 72, a side scraper 73, and a nozzle 74. The frame 71 is fixedly connected to the outer wall of one end of the water spray pipe 6 by a flange. The front scraper 72 is welded to the periphery of one side of the outer wall of the frame 71. The side scraper 73 is welded to the periphery of the side wall of the frame 71. The nozzle 74 is located at the center of one side of the outer wall of the frame 71.

[0028] The frame 71 of the descaling component 7 is fixed to one end of the spray pipe 6 via a flange. The flange connection facilitates the disassembly and replacement of the descaling component 7. The front scraper 72 can scrape off the scale in front, and the side scraper 73 can clean the scale on the side. The two work together to expand the scraping range. The nozzle 74 is located at the center of the outer wall on one side of the frame 71 and is connected to the spray pipe 6. It can spray high-pressure water to wash away the scale scraped off by the front scraper 72 and the side scraper 73, achieving a synergistic descaling effect of scraping and rinsing.

[0029] In this embodiment, the design of the buffer component 5 solves the problem of easy damage to boiler components during the descaling process. The buffer structure composed of the connecting sleeve 51, the guide tube 52 and the spring 53 can provide elastic buffer when the descaling component 7 comes into contact with the inner wall of the boiler or the heat exchange tube, thus avoiding damage caused by rigid collision.

[0030] A mounting sleeve 9 is welded to the bottom of one side of the outer wall of the housing 1, and a handle 10 is installed on the bottom outer wall of both the housing 1 and the mounting sleeve 9. The water inlet pipe 12 is installed through the inner wall of the mounting sleeve 9. A switch 11 is installed on one side of the outer wall of the housing 1, and the switch 11 is connected to the servo motor 2 through a signal line.

[0031] The mounting sleeve 9 supports and guides the inlet pipe 12, preventing it from shaking during rotation and operation. The handle 10 at the bottom of the housing 1 and the mounting sleeve 9 facilitates handheld operation, improving stability and convenience. The operator can control the start / stop and speed of the servo motor 2 via the switch 11, thereby adjusting the rotation speed of the descaling component 7 to adapt to different descaling scenarios.

[0032] Working principle: When in use, the operator holds the handle 10 and inserts the descaling component 7 into the area to be descaled inside the boiler. The servo motor 2 is started by the switch 11. The servo motor 2 drives the drive gear 3 to rotate. The drive gear 3 meshes with the driven gear 4, which drives the water inlet pipe 12 to rotate. The water inlet pipe 12 drives the spray pipe 6 and the descaling component 7 to rotate synchronously through the buffer component 5.

[0033] External water enters the inlet pipe 12 through the water supply hose 8 and a rotary joint. The water flows through the inlet pipe 12 into the connecting sleeve 51 of the buffer assembly 5, then through the guide pipe 52 into the spray pipe 6, and finally out of the nozzle 74 of the descaling assembly 7 with high pressure. When the descaling assembly 7 comes into contact with scale, the front scraper 72 and the side scraper 73 rotate to scrape the scale, and the peeled scale is washed away by the water sprayed from the nozzle 74.

[0034] When the descaling component 7 comes into contact with the boiler inner wall or heat exchange tube under excessive pressure, the guide tube 52 slides into the connecting sleeve 51, compressing the spring 53. The elastic force of the spring 53 forms a buffer to prevent damage to the components.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
