Abstract

The invention provides a smoke collection device for steel welding in a railway laboratory, comprising a smoke treatment box arranged above the steel to be welded, the upper part of the smoke treatment box communicates with a reaction liquid container on the steel to be welded, and the reaction liquid container The liquid is heated and vaporized during welding and enters the soot reaction component set on the upper part of the soot treatment box. A waste liquid collection and treatment component is provided, and the waste liquid collection and treatment component communicates with the dissolution collection structure and the outside world. The invention not only has the effect of absorbing the harmful substances in the smoke, but also avoids the factors unfavorable to welding caused by the rotation of the fan blades.

Description

technical field [0001] The invention relates to the technical field of smoke and dust cleaning, in particular to a smoke and dust collecting device used for steel welding in a railway laboratory. Background technique [0002] Due to the needs of experiments in the railway laboratory, it is sometimes necessary to weld short steel materials, including laboratory reaction frames such as rails and other appliances. Steel welding is the process of placing the ends of two steels opposite each other, heating or heating + pressurizing, so that the ends of the two steels achieve interatomic bonding and connect them into one steel. Specific methods include flash welding, gas pressure welding, thermite welding, and arc welding. [0003] At present, steel welding usually adopts manual operation, because the smoke generated by welding in the railway laboratory contains a large amount of harmful substances, mainly Fe 2 o 3 , SiO 2 and MnO, among which MnO is the most harmful, so it is...
