The specific embodiment
As shown in Figure 1, a kind of steam washer, comprise the sealing rinse bath 110 that is cleaned workpiece 2 be used to taking up, for generation of and to the steam generator 120 of sealing rinse bath 110 delivery solvent heating steams, be used for the decompressor 130 to 110 decompressions of sealing rinse bath, for detection of the temperature-detecting device 140 of the temperature data in the sealing rinse bath 110, for detection of the pressure-detecting device 150 of the pressure data in the sealing rinse bath 110, and control device 160.The data that control device 160 detects according to temperature-detecting device 140 and pressure-detecting device 150, control is to the conveying of the solvent heating steam of sealing rinse bath 110 and to the discontinuity decompression of sealing rinse bath 110.
After steam clean begins, because the liquefaction of can condensing at once after being cleaned workpiece 2 and coming in contact of solvent vapo(u)r and low temperature seals the phenomenon that rinse bath 110 internal pressures rise rapidly so can not produce because the solvent vapo(u)r importing makes.But along with the surface temperature that is cleaned workpiece 2 rises, until when being close with the temperature of solvent vapo(u)r, the condensation number of solvent reduces, the pressure that seal in the rinse bath 110 this moment also can begin to rise gradually.Along with the pressure rise in the sealing rinse bath 110, the boiling point of solvent will raise, thus cause solvent vapo(u)r with generation liquefaction phenomenon before cleaned material contact, cause the solvent vapo(u)r cleaning efficiency low.In order to prevent that above-mentioned situation from occuring, the utility model reduces pressure to sealing rinse bath 110 interior enforcement discontinuity after steam clean begins.After being depressurized in the sealing rinse bath 110, temperature can temporarily descend in the groove, as long as but stop decompression, because the steam of solvent, the temperature in the sealing rinse bath 110 can rise again.So, after steam clean begins, on one side the temperature in the rinse bath can produce cyclically-varying, Yi Bian rise.And, along with being cleaned the heat exchange of workpiece 2 with solvent vapo(u)r, when being heated near the center that is cleaned workpiece 2, the amplitude of variation of temperature will diminish gradually in the groove that is caused by discontinuity decompression, according to above-mentioned decision procedure, when this range of temperature reaches below the predetermined value, and the temperature in the above-mentioned sealing rinse bath 110 reach predetermined critical above that time, judge that steam clean finishes.
As shown in Figure 1, in order to input instruction and setting from the outside, this equipment also is provided with operating means 170, and operating means 170 is connected with control device 160.
As shown in Figure 1, sealing rinse bath 110 comprises cell body 111 and seal cover board 112, and seal cover board 112 is located on the cell body 111, particularly, cell body 111 tops are provided with opening, and opening is by cover plate 112 sealings, cover plate 112 is provided with air admission valve V1 and atmospheric open valve 113, and both are connected.
As shown in Figure 1, particularly, steam generator 120 is carried pipe arrangement 3 by steam and is returned liquid pipe arrangement 4 and is connected with sealing rinse bath 110, dispose heater 121 in the steam generator 120, be used for cleaning solvent is heated into steam, steam carries pipe arrangement 3 to be provided with steam transfer valve V3, returns liquid pipe arrangement 4 and is provided with back liquid valve V4.
Be depressurized the rinse bath 110 in the gas that device 130 attracts from sealing and contain fine droplet, go in order to prevent liquid to invade in the decompressor 130, is furnished with drop heater 180 at decompression pipe arrangement 5, this drop heater 180 encases part decompression pipe arrangement 5, fine droplet is gasified totally after being heated by drop heater 180 time.
Pressure-detecting device 150 can use the absolute vacuum gauge that numerical value change can not occur because of atmospheric pressure, i.e. hot-wire manometer.
When sealing rinse bath 110 was reduced pressure, if seal rinse bath 110 internal pressures less than or equal to preset pressure Pa, then instruction control unit 161 stopped decompression.
To sealing rinse bath 110 delivery solvent heating steams, when workpiece 2 is cleaned, if sealing rinse bath 110 internal pressures more than or equal to preset pressure Pb, then instruction control unit 161 stops delivery solvent heating steam, and sealing rinse bath 110 is reduced pressure.
It is to be noted, implementing decompression, ideal situation is to stop steam generator 120 to sealing rinse bath 110 interior delivering vapors, but because the enforcement of decompression, the velocity of discharge of steam is very fast in the rinse bath, in this case, also can not stop steam generator 120 to sealing rinse bath 110 interior delivering vapors, namely when sealing rinse bath 110 internal pressures more than or equal to preset pressure Pb, do not need to stop 120 work of steam generator, directly sealing rinse bath 110 being reduced pressure gets final product.
If the range of temperature in the sealing rinse bath 110 is less than or equal to preset temperature amplitude of variation △ Ta, and the temperature in the sealing rinse bath is then cleaned and is finished during more than or equal to preset temperature Tb.
As shown in Figure 2, cleaning process of the present utility model is as follows:
S110, with workpiece 2 put into the sealing rinse bath: the user opens seal cover board 112, workpiece 2 put into the sealing rinse bath 110, close cover plate 112.
S120, generation steam: (for example put into solvent 120 li of steam generators, common hydrocarbon solvent NS100), the user assigns the indication of processing beginning by 170 pairs of control device 160 of operating means, this timed unit 160 is closed steam transfer valve V3 and time liquid valve V4, and begins heater 121 is switched on.According to above-mentioned action, solvent is heated rear generation solvent vapo(u)r.
S130, the sealing rinse bath is reduced pressure: control device 160 cuts out air admission valve V1, and opens air bleeding valve V2, and decompressor 130 is brought into operation, and sealing is carried out vacuum in the rinse bath 110 and imported.Owing to being in decompression state in the cleaning-drying groove, when steam clean, the solvent vapo(u)r in the sealing rinse bath 110 is promoted diffusion, thereby makes cleaning efficiency higher.In addition, when sealing was in decompression in the rinse bath 110, the boiling point of solvent was lower than the boiling point under the standard state, even therefore high boiling solvent also can be kept gaseous state when temperature is low.
S140, control device 160 monitor the output data of pressure-detecting device 150, when sealing rinse bath 110 internal pressures drop to less than or equal to preset pressure Pa(such as Pa=7300 handkerchief), then close air bleeding valve V2, stop decompression;
S150, to sealing rinse bath 110 delivery solvent heating steams, workpiece 2 is cleaned: control device 160 is opened steam transfer valve V3, and the solvent vapo(u)r that the steam generator is 120 li carries pipe arrangement 3 to provide in sealing rinse bath 110 with certain speed by steam.At this moment, because the temperature of solvent vapo(u)r is higher than the temperature of workpiece 2, solvent vapo(u)r carries out heat exchange in workpiece 2 surface condensations when cleaning this workpiece 2 surface, and workpiece 2 is heated.
Clean the moment after engineering begins, after the workpiece 2 of solvent vapo(u)r and low temperature comes in contact, owing to liquefying immediately, therefore can not produce the situation that the groove internal pressure is risen rapidly because of the importing of solvent vapo(u)r.But along with the surface temperature of workpiece 2 raises gradually, when close to the temperature of solvent vapo(u)r, the condensation number of solvent is fewer and feweri, and the pressure in the groove also can rise gradually.
In the time of the pressure rise (that is to say under the low vacuum) in the sealing rinse bath 110, solvent boiling point rises, and solvent vapo(u)r before contact workpiece 2 liquefaction phenomenon occurs, and therefore can cause the steam clean decrease in efficiency.For fear of this situation, when implementing to clean engineering, be necessary to make the pressure in the sealing rinse bath 110 to keep within the specific limits.
At this moment, S160, control device 160 monitor the output data of pressure-detecting device 150, as shown in Figure 3, along with the importing of solvent vapo(u)r, the pressure in sealing rinse bath 110 is more than or equal to preset pressure Pb(Pb〉Pa, Pb=11300Pa for example) time, steam off transfer valve V3 within this time when steam supply temporarily stops, opening air bleeding valve V2, and by decompressor 130 beginning vacuum importings, namely return step S130.
It is to be noted, implementing decompression, ideal situation is to stop steam generator 120 to sealing rinse bath 110 interior delivering vapors, but because the enforcement of decompression, the velocity of discharge of steam is very fast in the rinse bath, in this case, also can not stop steam supply, namely the pressure in sealing rinse bath 110 is more than or equal to preset pressure Pb(Pb〉Pa, Pb=11300Pa for example) time, do not need to stop steam supply, directly open air bleeding valve V2, and got final product by decompressor 130 beginning vacuum importings.
Afterwards, when the pressure drop in the groove time the above-mentioned pressure value P a, close air bleeding valve V2, stop to import vacuum, open steam transfer valve V3, steam imports and restarts.
Because vacuum imports, and the temperature in the sealing rinse bath 110 temporarily reduces, afterwards along with stopping of vacuum importing and restarting that steam imports, the temperature in the sealing rinse bath 110 will rise again like this.In implementing cleaning process, to be interrupted like this and to carry out vacuum and import (that is to say vacuum import and stop to repeat), the temperature that the sealing rinse bath is 110 li rises gradually in the periodically variable while as Fig. 4 and Fig. 5 are represented.
Afterwards, along with workpiece 2 and solvent vapo(u)r carry out heat exchange, when near the center that is heated to workpiece 2, import even carry out vacuum, the temperature in the groove also can become and be difficult for descending again.Thus, along with the vacuum importing of above-mentioned discontinuity, the amplitude △ t that temperature changes up and down in the groove can diminish gradually.
At this moment, S170, control device 160 continue to monitor the output data of temperature-detecting device 140, said temperature amplitude of variation △ t drops to the Ta less than or equal to preset temperature amplitude of variation △, when sealing simultaneously temperature t in the rinse bath 110 more than or equal to preset temperature Tb, can judge that steam clean finishes.
In addition, △ Ta and Tb can draw exact numerical values recited by test.Above-mentioned every numerical value can be set storage by storage element 162 when the equipment shipment, also can carry out arbitrary value by operating means 170 by operating personnel and set, and then be stored by storage element 162.
Temperature determination flow as shown in Figure 6.Here, at first judging unit 163 detects temperature t (S2I0 stage) in the present groove by temperature-detecting device 140.Compare with temperature in the groove that approaches the front detection of measurement, can judge whether temperature descends (S220 stage) in the groove.Till drawing result of determination and be YES to S220, can repeat to implement in the fixed time interval at S210 and S220.
Along with the beginning that vacuum imports, the drop in temperature in the sealing rinse bath 110, if judge it is YES in the S220 stage, judging unit 163 can again be measured the temperature t in this time slot and obtain numerical information (S230 stage) after setting the time.Compare with temperature information in the groove of obtaining before approaching the measurement, can judge whether temperature rises (S240 stage) in the groove.Till drawing result of determination and be YES to S240, can in S230 and interval that S240 fixes time, repeat to implement.
Along with stopping of vacuum importing and restarting that steam imports, temperature will rise again in the groove, in the situation that the S240 phase judgement is YES, judging unit 163 is measured minimum of a value Tmin and the maximum of T max of temperature in the groove in the time before judging, and, calculate the difference between this minimum of a value Tmin and the maximum of T max, as the amplitude of variation △ t(S250 stage of temperature in the groove), and judge for example 4 ℃ of this amplitude of variation △ t and the definite value △ of institute Ta(in advance) compare and whether reduce (S260 stage).At this moment, if when range of temperature △ t surpasses the situation of institute's definite value in advance (result of S260 is NO), return the S2I0 stage, repeat the action between S2I0～S260.
If, range of temperature △ t is when the definite value △ Ta of institute is following (S260 is YES), then, judge temperature t (or above-mentioned maximum tmax in this time slot, or above-mentioned minimum of a value tmin) whether have for example 95 ℃ of critical value Tb() above (S270 stage), if do not reach in the situation of critical value Tb (S270 is NO), return S210, carry out to repeating between the S270 at S2I0.
When range of temperature △ t in the groove (S270 is YES) when critical value Tb is above, finish (S280) by judging unit 163 judgement steam clean.Control module 161 receives the rear steam off transfer valve V3 of this indication and air bleeding valve V2, and the cleaning engineering is finished.
S180, drying: after cleaning is finished, control device 160 open air admission valve VI destroy the vacuum of sealing rinse bath 110, the solvent vapo(u)r that is full of in the groove is liquefied, then, the solvent of opening back after liquid valve V4 will liquefy is recovered in the steam generator 120 by returning liquid pipe arrangement 4; Then, close back liquid valve V4 and air admission valve VI, open air bleeding valve V2, make decompressor 130 entrys into service, with the pressure explosive decompression in the sealing rinse bath 110 to can be with till sticking to the degree of the solvent generating gasification on the workpiece 2.At this moment, because the boiling point of solvent descends rapidly, stick to workpiece 2 lip-deep solvent generation bumpings and be vaporized, reach thus the dry tack free of workpiece 2.
S190, pickup: after drying was finished, decompressor 130 stopped, and also was stopped toward the energising of heater 121, closed back liquid valve V4 and air bleeding valve V2, then opened air admission valve VI, and the pressure that sealing rinse bath 110 is interior is for returning back to atmospheric pressure.After the temperature of rinse bath to be sealed 110 inside fully descends, open cover plate 112 and take out workpiece 2.
