Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to a stretching type boiler header cleaning device, belonging to the technical field of boiler header device cleaning. Background Art

[0002] As an important working fluid collection, mixing and distribution equipment for boiler pipelines, headers are one of the important components of boilers. At present, in the production process of headers, drilling, welding and heat treatment processes are used, and rust, burrs, welding slag and other debris are inevitably present, which affects the cleanliness of the inside of the header and poses a safety hazard to the operation of the boiler.

[0003] Due to the long length and small holes of the header, it is difficult to clean the inside of the header. In addition, the construction site is in a messy processing environment. The conventional operation in the existing technology is to place the header vertically and knock it from the outside to make the debris fall out. This still affects the cleanliness of the inside of the header and poses a safety hazard to the operation of the boiler. Utility Model Content

[0004] The technical problem to be solved by the utility model is: to overcome the drawbacks of the prior art due to the long length of the header, the small holes and the great difficulty in cleaning the inside of the header, and to provide a stretchable boiler header cleaning device which can be easily manufactured on site. The iron wire is pulled back and forth by the pull ring and the pull ear to prompt the grinding element to grind the inner wall of the header, thereby achieving the cleaning of the inner surface of the header and ensuring its cleanliness.

[0005] The technical solutions adopted by the utility model to solve the technical problems are as follows:

[0006] A stretching type boiler header purification cleaning device comprises a pull ring, a pull ring buckle, an iron wire, a grinding element, a clamp and a pull ear. The pull ring is fixedly connected to the pull ring buckle and is arranged at one end of the iron wire. The other end of the iron wire is provided with a pull ear. A grinding element is fixed on the iron wire, and a clamp is arranged outside the grinding element.

[0007] The grinding element comprises a fixing clip, a spring and an arc-shaped grinding sheet. The fixing clip is fixed on the iron wire. A spring is arranged on the outside of the fixing clip. An arc-shaped grinding sheet is arranged on the outside of the spring. The outer surface of the arc-shaped grinding sheet is provided with a grinding-resistant rough layer.

[0008] The grinding element is one or more than one and is fixed on the iron wire at equal intervals.

[0009] A pair of mutually symmetrical springs are arranged on the outer side of the fixing clamp, and an arc-shaped grinding sheet is arranged on the outer side of each spring.

[0010] The clamp is a structure of two semicircular rings, which are fixed together by connecting bolts to facilitate the free opening and closing of the clamp.

[0011] The other end of the pull ear is movably connected to a pull ring, or a traction rope of matching length is set according to the length of the polished component.

[0012] When in use, the pulling ear is sent into the header from the pipe opening at the head of the header, and the pulling ear is pulled out after reaching the pipe opening at the tail of the header. When the device is sent into the header, the bolts on the clamp are simultaneously opened to remove the clamp. After the clamp is removed, the springs on the grinding element are fully expanded to push the arc-shaped grinding sheet to move to the inner wall of the header. By pulling the pull ring and the pulling ear back and forth, the arc-shaped grinding sheet grinds and cleans the inner wall of the header, thereby cleaning the inner surface of the header and ensuring its cleanliness.

[0013] If the header pipe is relatively long and the length of the utility model is limited, a traction rope is set at one end of the pull ear, one end pulls the pull ring, and the other end pulls the traction rope. By stretching the iron wire back and forth, the grinding element grinds the inner wall of the header, thereby cleaning the inner surfaces of different headers.

[0014] The positive and beneficial effects of the utility model are as follows:

[0015] 1. The utility model has a simple structure, is easy to be processed and manufactured on site, and has a high cleaning effect.

[0016] 2. The utility model can improve the cleaning efficiency and cleanliness of the header, ensure the safe operation of the boiler equipment, and eliminate potential safety hazards.

[0017] 3. The utility model is easy to operate. By pulling the pull ring and the pull ear to stretch the iron wire back and forth, the grinding element grinds the inner wall of the header, thereby cleaning the inner surfaces of different headers and ensuring their cleanliness.
