Description

Volatile liquid gas burning oxygen welder

The utility model relates to gas welding, cutting mill, relates in particular to a kind of gas welding of combustion gas oxygen, cutting mill of volatilizable liquid.

Existing gas welding, cutting mill are made of gas welding, the cutting mill of combustion flame acetylene gas, oxygen mix, this kind gas welding, cutting mill are the very active gas of a kind of chemical property because of acetylene gas, it all easily mixes in wide range with air and may set off an explosion, so dangerous; And acetylene gas itself is to adopt calcium carbide to add water to generate, thus in the production process that produces acetylene gas always stink scatter and contaminated environment and injury health; In addition, the manufacturing of calcium carbide extremely takes.So, adopt acetylene gas do combustion gas no matter from making apparatus with energy consumption and becomes to see all very uneconomically and dangerous originally, when adopting acetylene generator to produce acetylene gas,, return carrying and bring difficulty, so press for improvement because of its volume is big, in light weight.

The purpose of this utility model be to design a kind of handling safety, easy, volume is little, in light weight harmless to health, cost is low, the novel gas welding of convenient in carrying, cutting mill.

The purpose of this utility model is achieved in that with a gas generator, replace original acetylene gas generator, described gas generator is made up of the temperature application cylinder in the hot water barrel and the hot water barrel that packs into, combustion gas generation tube, gas heat-exchange tube, be equiped with temperature controller and heater in the temperature application cylinder, the good liquid combustion body of the volatilizable performance of more than half tube takes place to place in the tube in combustion gas, and the bottom that tube takes place in combustion gas is provided with a gas sparge ring that links to each other with the pressurized hot gas pipe.The good liquid fuel (gasoline of volatility in the tube takes place in combustion gas, alcohol, kerosene, diesel oil etc.) under the heat effect of hot water, make liquid fuel gasification, and the effect of the hot gas that has certain pressure that ejects by gas sparge ring aperture, liquid fuel is seethed up and down, thereby quicken the gasification of volatilizable liquid, atomizing, these gasifications, the combustible gas of atomizing flow to the upper space that tube takes place in combustion gas fast with some hot-airs, and mix fully once more, the pipe joint of tube upper end then takes place by combustion gas, tube connector and valve cause the former acetylene joint of soldering set (cutter), are used for burning and a cutting with oxygen, the usefulness of welding.

This gas welding, cutting mill not only quicken volatilizable liquid gasification, but also can make the partially liq atomizing because of the sparge ring that has spray-hole that it adopted, so its mixed combustible gas calorific value is very high, can cut the thick steel plate of 100mm, and its otch is still very neat.As spray gas and adopt when the oxygen of pressure is arranged, then its fuel gas temperature higher, can cut that thickness is thicker, the advantage of this gas welding, cutting mill is: simple for production, volume is little, (being not more than 10 kilograms) in light weight, handling safety is used easy to carry, energy consumption is little, the flame temperature height can cut steel plate, thus be used for scrapping, the shipbuilding industry fitting and decoration of ship's space, house decoration and other need cut, the gas welding occasion.
