Description
Technical field
The present invention relates to a kind of retracting device and use the recovery method of this retracting device, relate in particular to a kind of liquid withdrawal system and use the liquids recovery method of this retracting device.
Background technology
Spray paint, in the cleaning process, spray liquid has only part to spray on the workpiece, all the other are not sprayed onto that spray liquid on the workpiece then 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 for hindering a key factor of current social development, for guaranteeing the sustainable development of society, the theme that advocate thriftiness, environmental protection is listed in current society, so no matter be from saving cost or from the aspect of environmental protection, or even consider that from the aspect of social development the spray liquid that this part is rationally utilized is recycled and seemed particularly important.
For this reason, the applicant is devoted to study the recovery method of spray liquid, and has carried out repeatedly experiment, reclaims spray liquid in the hope of efficient, economy, environmental protection ground.Utilize reclaiming the 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 again, and the viscosity that promptly reclaims liquid is not too high.
See also Fig. 1, at first, adopt the method that directly reclaims, promptly use the retracting device 10 that comprises funnel 11 and directly be positioned over the liquid storage bottle 12 of funnel 11 belows.During collection, stoste 13, promptly without the paint that uses, ejection from spray equipment 14, part is sprayed onto on the workpiece 15, and part flows down from funnel 11 and enters the liquid storage bottle 12, collects in the liquid storage bottle 12 and obtains reclaiming liquid 16.Recovery liquid in stoste 13 and the liquid storage bottle 12 16 is carried out sampling and measuring, and measurement data is the viscosity of paint, and unit is centipoise (CP), and concrete experimental data is 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 this method reclaims all meets the requirements, and is fit to follow-up recycling.In the method, reclaim liquid 16 and directly enter in the liquid storage bottle 12 and only top layer liquid-to-air contact, solvent evaporates is less, thus viscosity be in former fluid viscosity～8.5 centipoise intervals, can be not too high.Yet, 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 a large amount of air to enter liquid storage bottle 12, an end opening of funnel 11 insertion liquid storage bottles 12 is less, so recovery liquid 16 flow velocitys can stop up an end of funnel 11 liquid storage bottles 12 when slow, the paint that causes can't continuing not spraying on the workpiece 15 reclaims.Simultaneously, reclaiming liquid 16 from the slowly dirty process of funnel 11, partially recycled liquid 16 may be air-dry, and then be bonded at funnel 11 inboards, after long-time the use, the air-dry recovery liquid 16 of bonding one deck on the funnel 11, can reuse after need pulling down cleaning, otherwise spray-painting plant 14 can't work on, waste man-hour, further reduced organic efficiency.And be bonded at that part of recovery liquid 16 on the funnel 11 because solvent is most of lost, utilization has again increased production cost, has caused the environmental pollution and the wasting of resources after can't adjusting.
If save funnel 11, and the collection of directly liquid storage bottle 12 alignment pieces 15 being reclaimed liquid 16, then in collection process, when the recovery liquid 16 in the liquid storage bottle 12 is accumulated to when a certain amount of, need liquid storage bottle 12 is pulled down from retracting device 10, during this period, spray equipment 14 also can't work on, waste man-hour, organic efficiency reduces.
See also Fig. 2, for addressing the above problem, the applicant has further improved recovery method, use comprises funnel 31, collection box 32, recovery pump 33, liquid storage bottle 34 and is communicated with the retracting device 30 of the pipeline 35 of collecting box 32, recovery pump 33 and liquid storage bottle 34 successively, in spray equipment 36 spray processes, reclaim liquid 37 and flow into collection box 32 from funnel 31, the recovery pump 33 by continuous firing is collected into the liquid storage bottle 34 of sealing through pipeline 35 from collecting box 32 extractions again.The recovery liquid of collecting in the liquid storage bottle 34 37 can utilize after adjustments such as solvent are handled again through adding.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 this method reclaims all exceeds allowed band, is not suitable for follow-up recycling.Contrast two kinds of recovery methods and find, use the recovery fluid viscosity that reclaims pump 33 than not using recovery pump 33 to obtain to be higher than former fluid viscosity～8.5 centipoises, problem may be for the use of reclaiming pump 33.By analysis, the volatilization of solvent is the key factor that influences spray liquid viscosity, recovery pump 33 is in normally open in the scheme that reclaims pump and use, when extracting the recovery liquid of collecting in the box 32 37, can and reclaim liquid 37 suction liquid storage bottle 34 together with a large amount of air, in the process that extracts, form air and the compounding substances that reclaims liquid 37, make that reclaiming liquid 37 fully contacts with air, solvent volatilizees in a large number, causes reclaiming liquid 37 viscosity and increases.And after a large amount of gases are drawn into liquid storage bottle 34, recovery liquid 37 long-time and in the liquid storage bottle 34 contacts, make the recovery liquid 37 in the liquid storage bottle 34 not only continue volatilization, and oxidation deterioration takes place easily, cause the recovery liquid 37 that is recovered to reuse, maybe need carry out comparatively complicated adjustment and just can reuse, increase production cost, cause the pollution of environment and the waste of resource simultaneously.
From above-mentioned applicant's repeatedly experiment as can be known; how a kind of liquids recovery method is provided, uses this liquids recovery method both can guarantee organic efficiency, can guarantee to reclaim the quality of liquid again; and then reduce the environmental pollution and the wasting of resources, become a problem demanding prompt solution.
