Description
Technical field
The utility model belongs to metal working technical area, and in particular to a kind of overcritical titanium dioxide for intermetallic composite coating
Carbon compound atomizing jet.
Background technology
In various metals process, (some non-limiting examples of process of metal working include metal working fluid (MWF)
Working angles, forming process etc.) during lubrication and cooling metal and useful to appropriate machining function.Specifically, MWF increases
Life tools, appropriate surface smoothness is ensured significantly, it is allowed to the faster manufacture rate and energy during reducing machining disappears
Consumption.Metal working fluid is typically water-in-oil emulsion, wherein oil lubrication cutting band, and water cooling cutting band.However, oil and water
Mixture is there is a possibility that MWF causes environmental problem and occupational health problem.This may be attributed to (at least partly so) can be
Metal, organic principle and the microorganism of aggregation in these fluids, and these liquid are excessively sprayed in pole in mechanical processing process
When the aerosol that is likely to form.The air quality in workshop can be reduced by the aerosol that these oil solutions are formed and some
In the case of may potentially cause that acute and/or chronic skin influences and lung influences on worker.Water-in-oil emulsion is easily because micro-
Biological attack and hard water ion accumulation and there is Quality Down with the time, this may cause waste disposal issues, especially when mixed
When compound contains poisonous additive.Therefore when MEF reaches final service life, they can become bazardous waste.If
Other solvents than water can be used to provide the lubrication of minimum, then can be substantially eliminated relevant with MWF many
Environmental problem and health problem.
Therefore, it is desirable that the metal working lubricant that minimum necessary amounts are provided using nonaqueous solvents is acted on.Such replacement
Property solvent can advantageously reduce or eliminate the problem of relevant with water base MWF, and therefore reduce or eliminate to traditional MWF safeguard
The needs of system or processing system such as pump and piece-rate system.In addition, sending the lubrication for passing minimum to protect resource, more one is maintained
The high quality process operation of cause, and reduce service life cycle emissions, at the same time go far towards to eliminate potentially with tradition
Health risk relevant water base MWF and spoilage problems.
The beneficial effects of the utility model be that it is possible to improve intermetallic composite coating efficiency and recovery, be reduced to manufacture product
The amount of required raw material；The intermetallic composite coating solution additive such as chelating agent using auxiliary can be avoided, these additives can band
Carry out process problem；It is compatible with a variety of traditional and unconventional base oil, can if any high oxidation stability, durability and recycling
The fluorinated oil and surfactant of energy property, the service life cycle bears less vegetable oil and tool for oil replacement thing
There is the petroleum based oil of surfactant.
Utility model content
In view of this, the utility model provides a kind of supercritical carbon dioxide compound atomizing jet for intermetallic composite coating,
The efficiency and recovery, the amount for being reduced to manufacture raw material required for product of intermetallic composite coating can be improved, it is and a variety of traditional and non-
Traditional base oil is compatible, is the effective means of metal working lubricant.
The technical solution of the utility model is：A kind of supercritical carbon dioxide compound atomizing jet for intermetallic composite coating,
It is characterised in that it includes atomizer, the atomizer inside is provided with water inlet pipe, oil inlet pipe, carbon dioxide conduit, compressed air hose
Road, the atomizer are connected with tracheae, and the tracheae connects with compressed air piping, the water inlet pipe, oil inlet pipe, carbon dioxide
Pipeline is parallel to be located at the pipe, and the tracheae end is provided with nozzle, the water inlet pipe, oil inlet pipe, carbon dioxide conduit
End at the nozzle.
Further, the horizontal cross-section of the nozzle is the combination of rectangle and isosceles trapezoid.
Further, the front end injection diameter of the nozzle is 0.1-0.25mm.Preferably, the spray orifice of tracheae front end nozzle
Diameter is to preferably keep pipeline pressure in 0.15mm.
Further, the compressed air piping is connected with pulse valve.
Further, it is provided with heat-insulation layer outside the compressed air piping.
Further, the heat-insulation layer is provided with heating wire.The heater strip set in the utility model, it is to add to pipeline
Heat insulation, to reach supercritical carbon dioxide state.
Further, the carbon dioxide conduit is connected with high-pressure carbon dioxide source.
Further, the water inlet pipe is provided with water regulating valve.
Further, the oil inlet pipe is provided with director valve, and the oil inlet pipe is connected with oil pump.
In the utility model, atomizer has four entrances, and water, oil, supercritical carbon dioxide, gas, one functions as
Fixed block, which is fixed, gathers these pipelines, and another effect is that have water regulating valve on atomizer, in that context it may be convenient to the flow of water is adjusted,
Because wanting the effect for reaching Oil on Water Water-In-Oils, the flow of water will control, and this water regulating valve is near from spray outlet,
Can be while adjusting, while the effect of droplet is observed, to be transferred to proper ratio.
Particularly, in the utility model, when oil is come in, it is atomized by oil pump, there is a regulating valve on oil pump, can be with
The size of adjusting oil mass.
Compressed air divides two-way to come in, and one is to blow always, water is dispelled into atomization, and profit mist is blown into cutter
On；Another way is controlled by a time pulse valve, and big air-blowing once in a while once, can be by the ice of supercritical carbon dioxide jet pipe front end
Block is blown off, in case ice cube stops supercritical carbon dioxide outlet.
Lubricant is for example pure oily (straight oil), i.e., does not add the oil of water, be for most process most
Known lubricant.And the utility model people also found supercritical CO2Combination with water-in-oil emulsion lubricant has favourable
Concertedness, i.e., measured lubricating ability is substantially more preferable during by the lubricating ability that the combination measures than alone any of which.Also
It was found that when oil is in supercritical CO2When being inside delivered, even if applying less oil to system, above-mentioned concertedness is also showed that.When with
Same supercritical CO2When sending the delivery system to be used together, with lesser amount of identical oil, it has been found that the result of these improvement.
Although supercritical CO2Extraction process, etching just as pharmaceuticals industry and in semi-conductor industry and Chemical Engineering
The important composition of process and cleaning process, but supercritical CO2The advantageous use in metal-processing industry is not shown so far.
The utility model people has found, by controlling supercritical CO2, compressed air, water, atomization oil be added to cutting zone amount ratio,
So as to improve efficiency and recovery, and reduce manufacture the fluid required for raw material amount.Therefore supercritical CO2Use can quilt
