Abstract
The invention relates to a protective atmosphere generating device, which comprises an air filter, a raw material gas inlet, a mixer, a flame arrester, a combustion furnace, a water tank, a gas outlet filter, a cooler, a cold drying device and a gas outlet, wherein a resistor-type igniter is employed in the combustion furnace. A blower is arranged on the air filter, a flame observation hole is arranged on the combustion furnace. When the protective atmosphere generating device operates, air is introduced from the air filter, the combustion gas is introduced from the raw material gas inlet, air and the combustion gas are mixed through the mixer and introduced in the combustion furnace through the flame retardation device, after completely combusting, the mixture is output to the cooler through the gas out filter, then is cooled through the cooler, moisture is removed through the cold drying device, and gas is supplied from the gas outlet on the cold drying device finally. The protective atmosphere generating device has light volume, and can be externally connected to gas or natural gas. The protective atmosphere generating device has the advantages of simple structure, low cost and convenient usage.
Description
Technical field
The present invention relates to production unit field, specifically protective atmosphere generating unit, is applicable to all kinds of occasions that need to use protective atmosphere.
Background technology
Controlled atmosphere English is controlled atmosphere, is the gas that a kind of composition using in order to protect metallic surface and adjusting metallic surface chemical composition when heating of metal can be controlled.When metal (being mainly steel) heats in controlled atmosphere, surface oxidation or decarburization can be avoided, also surperficial carburetting can be made as requested.Controlled atmosphere is generally mixed by two or more gas, when when avoiding surface oxidation, also can adopt single gas as shielding gas, such as hydrogen, argon or nitrogen etc.Controlled atmosphere is mainly used in metal heat treatmet, also for forging stock less, nonoxidizing heating (see forging stock heating).Protective atmosphere is topmost part in controlled atmosphere, and for generation of the confining gas environment with corrosion protection component, wherein, exothermic atmosphere is a kind of as protective atmosphere, with its super quality and competitive price, liked by client.Exothermic atmosphere is divided into two kinds of dense type heat release atmosphere, light type heat release atmosphere.Dense type heat release atmosphere is mainly used in annealing, the normalizing of foundry goods, forging; soft steel, medium carbon steel light annealing, quenching; the heated protective of steel part tempering etc.; the conventional light of doing copper and copper alloy of light type exothermic atmosphere is processed; the annealing heating protection of malleable iron, and workpiece send out the processing such as orchid, blackout.
Traditional protective atmosphere source is mainly large-scale gas base station occurs, and for the less occasion of gas consumption, also there is no the protective atmosphere generating unit that a kind of volume is light and handy, simple in structure, raw material is common at present.
Summary of the invention
The present invention, just for above technical problem, provides the protective atmosphere that a kind of volume is light and handy, simple in structure, raw material is common generating unit.
The present invention is achieved through the following technical solutions:
Protective atmosphere generating unit, comprise air filter, raw material gas inlet, mixing tank, spark arrester, roasting kiln, water tank, go out air filter, water cooler, cold dry device, air outlet, it is characterized in that, between mixing tank and roasting kiln, spark arrester is set, air filter, raw material gas inlet is connected with mixing tank respectively, roasting kiln is connected with water cooler by going out air filter, water cooler outlet side connects cold dry device, air outlet is arranged on cold dry device, water cooler roasting kiln furnace shell is water-cooling sandwich, water outlet in roasting kiln, the water-cooling sandwich water outlet of roasting kiln furnace shell, water outlet on water cooler is all connected in water tank.In roasting kiln, adopt resistance-type lighter for ignition.On air filter, can install gas blower additional.On roasting kiln, be provided with glory hole.
When the present invention works, air enters from air filter, combustion gases enter from raw material gas inlet, after mixing tank mixes, by flame-retardant device, enter roasting kiln, after perfect combustion, through going out air filter, output to water cooler, after water cooler is cooling, by cold dry device, dehumidify, last by the external air feed in air outlet on cold dry device, this device volume is light and handy, can external coal gas or Sweet natural gas.
The present invention is simple in structure, with low cost, easy to use.
