Hearth welding flaw detection device and method for soot blower

Abstract

The invention discloses a hearth welding flaw detection device and method for a soot blower, and belongs to the technical field of hearth welding. The hearth welding flaw detection device comprises a first sleeve frame and a second sleeve frame, wherein the first sleeve frame and the second sleeve frame have the same structure and are horizontally and correspondingly distributed, a connecting assembly is fixedly mounted between the first sleeve frame and the second sleeve frame, clamping frames are fixedly arranged at the opposite ends of the first sleeve frame and the second sleeve frame in a clamped mode, a driving mechanism is arranged between the two clamping frames, a flaw detector and a cleaning assembly are arranged in the driving mechanism, guiding assemblies are fixedly installed on the outer walls of the first sleeve frame and the second sleeve frame, and moving assemblies are fixedly mounted on the outer walls of the first sleeve frame and the second sleeve frame. According to the flaw detection device, a cleaning assembly is arranged at the position adjacent to the flaw detector, debris cleaning can be carried out on a welding part before flaw detection is carried out on the welding part, therefore the debris is prevented from influencing flaw detection on the welding part, and the flaw detection effect of the whole device is improved.

Description

technical field [0001] The invention relates to the technical field of furnace welding, in particular to a furnace welding flaw detection device and method for a sootblower. Background technique [0002] Soot blower is a device used to remove soot on the heating surface of the boiler. It is usually composed of soot blowing pipes and operating valves. It is often used in industrial boilers and is generally installed in the boiler furnace, horizontal flue and tail flue, etc. The furnace wall of the sootblower needs to be welded to the furnace wall of the sootblower when it is used. After welding, it is necessary to perform flaw detection on the welded part of the furnace to prevent the water-cooled wall from bursting when the sootblower is used. [0003] However, most of the existing furnace welding flaw detection devices have relatively simple structures. When performing flaw detection on the welded part of the inner wall of the furnace tube, the flaw detector needs to be tra...

Problems solved by technology

[0003] However, most of the existing furnace welding flaw detection devices have relatively simple structures. When performing flaw detection on the welded part of the inner wall of the furnace tube, the flaw detector needs to be transported to the furnace tube, and the flaw detector needs to be manually rotated to adjust the position of the flaw detector. It is troublesome to perform flaw detection on the furnace tube, and if debris appears in the welding part, it will easily affect the effect of flaw detection if there is no effective cleaning. Therefore, we propose a furnace welding flaw detection device for soot blowers and method to solve the above problems
