Novel magnetic slag removing device

Abstract

The invention provides a novel magnetic slag removing device. The novel magnetic slag removing device comprises an adjustable snake-shaped pipe and a magnetic device which are connected through a thread, and detaching and replacing can be convenient. The adjustable snake-shaped pipe is a flexible pipe, can be freely bent on various joints of the full length, and can adapt to boiler pipelines in various complicated shapes, so that no dead corners exist during boiler pipeline clearing any more; and a ferromagnetic magnet is embedded in the magnetic device, and can attract welding slag and iron scraps remaining in a boiler pipeline. During removing, the magnetic device is firstly stuffed into the boiler pipeline; then by means of the adjustable snake-shaped pipe, the magnetic device is pokedinto the pipeline, the welding slag and the iron scraps remaining in the pipeline can be attracted by the magnetic device; and next, the snake-shaped pipe is drawn out, and it is only needed to clearway the welding slag and the iron scrap attracted on the magnetic device. The novel magnetic slag removing device can perform fast and efficient removing on the welding slag and the iron scraps remaining in the boiler pipelines in various complicated shapes, the removing effect and the work efficiency of overhauling personnel are greatly improved, and the removing time is shortened.

Description

technical field [0001] The invention relates to a slag removal device, in particular to a magnetic slag removal device for cleaning welding slag and iron filings in a boiler pipe of a thermal power plant, and belongs to the technical field of boiler maintenance. Background technique [0002] Boilers in thermal power plants contain a large number of pressure pipes. These pressure pipes must be clean, and iron impurities such as welding slag and iron filings are not allowed. Otherwise, the heating surface of the pressure pipes will be overheated and damaged, which will affect the entire generator set. of normal operation. [0003] Therefore, the welding slag and iron filings in the pressure pipeline must be cleaned up during boiler maintenance to avoid welding slag and iron filings remaining in the pipeline. In the past, this cleaning work was done manually. However, due to the complex and changeable shape of the boiler pipes, which are not straight pipes, there are many elbo...

Problems solved by technology

In the past, this cleaning work was done manually. However, due to the complex and changeable shape of the boiler pipes, which are not straight pipes, there are many elbows, and the space layout of the pipes is relatively compact, manual cleaning is not only difficult to operate, but also takes a long time. Moreover, many welding slag and iron filings at the dead corners of pipe elbows are difficult to clean up, leaving potential safety hazards easily
