Description
Technical field
The present invention relates to a kind of retracting device, relate in particular to a kind of liquid withdrawal system.
Background technology
Spraying paint, in cleaning process, spray liquid only has part to spray on workpiece, all the other are not sprayed onto that spray liquid on workpiece can spray other positions and the waste that causes spray liquid has improved production cost, and the spray liquid of this waste simultaneously also causes the pollution of environment.And a large amount of wastes of environmental pollution and resource are a key factor that hinders current social development, for guaranteeing social sustainable development, the theme advocate thriftiness, environmental protection being listed in society, therefore no matter be from saving cost or the aspect from environmental protection, or even from the viewpoint of social development, the spray liquid that this part is not obtained to rationally utilize is recycled and is seemed particularly important.
For this reason, the applicant is devoted to study the recovery method of spray liquid, and has carried out many experiments, to efficient, economy, environmental protection reclaim spray liquid.Recycle reclaiming liquid adjustment for ease of follow-up, in this experiment, the permission range of viscosities that reclaims liquid is former fluid viscosity～8.5 centipoises, and the viscosity that reclaims liquid is not too high.
Refer to Fig. 1, first, adopt the method directly reclaiming, use the retracting device 10 that comprises funnel 11 and be directly positioned over the liquid storage bottle 12 of funnel 11 belows.When collection, stoste 13, without the paint using, ejection from spray equipment 14, part is sprayed onto on workpiece 15, and part flows down and enters liquid storage bottle 12 from funnel 11, in liquid storage bottle 12, collects and is recycled liquid 16.Recovery liquid 16 in stoste 13 and liquid storage bottle 12 is carried out to sampling and measuring, and measurement data is the viscosity of paint, and unit is centipoise (CP), and specific experiment data are as shown in the table:
| The experiment date | Stoste (CP) | Reclaim liquid (CP) |
| On July 28th, 2009 | 4.14 | 7.65 |
| On July 29th, 2009 | 4.34 | 8.1 |
| On July 29th, 2009 | 4.34 | 7.8 |
From experimental data, the recovery fluid viscosity that the method reclaims all meets the requirements, and is applicable to follow-up recycling.In the method, reclaim that liquid 16 directly enters in liquid storage bottle 12 and only top layer liquid-to-air contact, solvent evaporates is less, thus viscosity in centipoise interval, former fluid viscosity～8.5, can be not too high.But, in this scheme, reclaiming liquid 16 and can only rely on self gravitation to enter liquid storage bottle 12 from funnel 11, flow velocity is slower.For avoiding large quantity of air to enter liquid storage bottle 12, the end opening that funnel 11 inserts liquid storage bottle 12 is less, one end of funnel 11 liquid storage bottles 12 can be stopped up when slower therefore reclaim liquid 16 flow velocitys, cause the paint that cannot continue not spraying on workpiece 15 to reclaim.Simultaneously, reclaiming liquid 16 from funnel 11 slowly dirty process, partially recycled liquid 16 may be air-dry, and then be bonded at funnel 11 inner sides, after long-time use, the recovery liquid 16 that the one deck that bonds on funnel 11 is air-dry, after need pulling down cleaning, can reuse, otherwise spray-painting plant 14 cannot work on, waste man-hour, further reduced organic efficiency.And be bonded at part on funnel 11 and reclaim liquid 16 and scatter and disappear because solvent is most of, cannot adjust rear re-using, increased production cost, caused environmental pollution and the wasting of resources.
If save funnel 11, and the collection of directly liquid storage bottle 12 alignment pieces 15 being reclaimed to liquid 16, in collection process, when the recovery liquid 16 in liquid storage bottle 12 is accumulated to when a certain amount of, liquid storage bottle 12 need be pulled down from retracting device 10, during this period, spray equipment 14 also cannot work on, waste man-hour, organic efficiency reduces.
Refer to Fig. 2, for addressing the above problem, applicant has further improved recovery method, use comprises funnel 31, disposable box 32, recovery pump 33, liquid storage bottle 34 and is communicated with successively the retracting device 30 of the pipeline 35 of disposable box 32, recovery pump 33 and liquid storage bottle 34, in spray equipment 36 spray processes, reclaim liquid 37 and flow into disposable box 32 from funnel 31, then extract through pipeline 35 and be collected into the liquid storage bottle 34 of sealing from disposable box 32 by the recovery pump 33 of continuous firing.The recovery liquid 37 of collecting in liquid storage bottle 34 can re-use through adding after the adjustments such as solvent are processed.Through measuring, obtain following experimental data:
| The experiment date | Stoste (CP) | Reclaim liquid (CP) |
| On July 28th, 2009 | 4.14 | 11.5 |
| On July 28th, 2009 | 4.45 | 12.6 |
From experimental data, the recovery fluid viscosity that the method reclaims all exceeds allowed band, is not suitable for follow-up recycling.Contrast two kinds of recovery methods and find, use recovery pump 33 is than the recovery fluid viscosity that does not use recovery pump 33 to obtain higher than former fluid viscosity～8.5 centipoise, and problem may be for the use of recovery pump 33.By analysis, the volatilization of solvent is the key factor that affects spray liquid viscosity, and use in the scheme of recovery pump recovery pump 33 in normally open, in the time of the recovery liquid 37 extracting in disposable box 32, can be by large quantity of air suction liquid storage bottle 34 together with reclaiming liquid 37, in the process extracting, form air and the compounding substances that reclaims liquid 37, make to reclaim liquid 37 and fully contact with air, solvent volatilizees in a large number, causes reclaiming liquid 37 viscosity and increases.And when a large amount of gas is drawn into after liquid storage bottle 34, contact with the recovery liquid 37 in liquid storage bottle 34 for a long time, make the recovery liquid 37 in liquid storage bottle 34 not only continue volatilization, and easily there is oxidation deterioration, cause the recovery liquid 37 being recovered to reuse, maybe need to carry out comparatively complicated adjustment and just can reuse, increased production cost, caused the pollution of environment and the waste of resource simultaneously.
From above-mentioned applicant's many experiments; how a kind of liquids recovery method is provided, uses this liquids recovery method both can guarantee organic efficiency, can ensure to reclaim again the quality of liquid; and then reduce environmental pollution and the wasting of resources, become a problem demanding prompt solution.
