Stainless steel and cast iron oxy-acetylene cutter

Abstract

The invention relates to an oxy-acetylene cutter, in particular to a stainless steel and cast iron oxy-acetylene cutter and solves the problems of powder blockage, lower service efficiency and only horizontal cutting of the traditional stainless steel and cast iron oxy-acetylene cutter. The stainless steel and cast iron oxy-acetylene cutter comprises a pure oxygen jet pipe, wherein a powder blowing device comprising a pipe body is arranged on the pure oxygen jet pipe, a by-pass pipe is arranged on the pipe body, and a powder bucket is connected with and fixed on the by-pass pipe; the pipe body is internally provided with a jet and absorption pipe, and the jet and absorption pipe is provided with a hole; the by-pass pipe on the pipe body is internally provided with an oxygen blowing channel; the cavity of the jet and absorption pipe is communicated with the powder bucket through the hole on the jet and absorption pipe and the oxygen blowing channel in the by-pass channel; and the end part of the oxygen blowing channel is connected with a metal bellows capable of being bent and deformed. The stainless steel and cast iron oxy-acetylene cutter increases the capacity of mixing or sucking iron powder and quartz sand by using high pressure oxygen, has smooth powder outlet and improves the cutting efficiency of the cutter, and meanwhile, the application scope of the cutter is enlarged, thus the cutter can be used for omnibearing cutting operations and has safe and reliable work.

Description

technical field [0001] The invention relates to an oxy-acetylene torch, in particular to a stainless steel or cast iron oxy-acetylene torch. Background technique [0002] Cutting steel structures with an oxyacetylene torch is the most basic and commonly used maintenance method in maintenance work. However, the traditional oxy-acetylene torch can only cut ordinary carbon steel, and it is helpless if it encounters materials such as stainless steel or cast iron. The method generally adopted now for materials such as stainless steel or cast iron is to cut with equipment such as plasma cutting machine, but like this not only has increased equipment cost, also is inconvenient to use in the maintenance process. Some improved oxyacetylene torches can cut stainless steel and cast iron. The principle is to blow quartz sand and iron powder into the oxyacetylene cutting, release a large amount of heat energy through intense oxidation and combustion, and form a high-temperature fluid t...
