Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated。
Embodiment as shown in Figure 1 is known, the present embodiment includes cleaning still and being positioned at the separating still of its underpart, clean the cleaning closed chamber that still includes being made up of with the hermatic door 2 being arranged on housing 1 housing 1, housing 1 is provided with thermostat, being provided with bowl basket pallet 3 and a rinser cleaning in closed chamber, rinser includes spray thrower 4 and ultrasonic transducer 5;Spray thrower 4 and ultrasonic transducer 5 are all directed at the tableware in the bowl basket 6 that bowl basket pallet 3 is lifted, and the pipeline connectivity port 4-1 of spray equipment is positioned at the outside of housing 1;Separating still includes gas-tight silo 7, and the top of gas-tight silo 7 is provided with gas-tight silo water inlet 8, gaseous carbon dioxide outlet 15 and air bleeding valve 9, and the bottom of gas-tight silo 7 is provided with blowoff valve 10, and the bottom cleaning closed chamber connects through the top of counterbalance valve 11 with gas-tight silo 7。
Bowl basket pallet 3 present position can make the tableware in the bowl basket 6 that bowl basket pallet 3 is lifted be in the middle part of cleaning closed chamber space;The spray thrower 4 cleaned in closed chamber is two, is symmetrically arranged at the both sides up and down of bowl basket pallet 3。
Cleaning closed chamber for sleeping can-shaped structure, hermatic door 2 is positioned at the end cleaning closed chamber。
The thermostat that housing 1 is provided with is: housing 1 is provided with the chuck layer 12 for the insulation water that circulates, and is provided with chuck layer water inlet 13 on the top of chuck layer 12, is provided with chuck layer outlet 14 in the bottom of chuck layer 12。
The chuck layer outlet 14 of chuck layer 12 bottom being arranged on the housing 1 cleaning still is connected with the gas-tight silo water inlet 8 on gas-tight silo 7 top of separating still by valve。
The gas-tight silo 7 of separating still is combined by the bullet 7-2 of the cylinder 7-1 of upper end He its lower end。
Operation principle:
The pipeline connectivity port 4-1 of the spray equipment of this device and gaseous carbon dioxide are exported 15 connectivity ports corresponding to supercritical carbon dioxide blood circulation connect, will be equipped with the bowl basket of tableware and be placed on bowl basket pallet, close hermatic door, open supercritical carbon dioxide blood circulation, owing to supercritical carbon dioxide should control temperature more than 32 DEG C, therefore need to be circulated chuck layer 12 by chuck layer water inlet 13 and chuck layer outlet 14 recirculated water of relevant temperature, to keep the temperature cleaning closed chamber, open spray thrower 4 and ultrasonic transducer 5, the high-frequency oscillation signal sent by supersonic generator, convert high frequency mechanical oscillation to by ultrasonic transducer 5 and propagate medium--in cleaning solvent, ultrasound wave is the forward directed radiation of density interphase in cleanout fluid, liquid flowing is made to produce the micro-bubble that ten hundreds of diameters is 50-500 μm, it is present in the micro-bubble in liquid to vibrate under the effect of sound field。These bubbles are formed at the negative pressuren zone of ultrasound wave longitudinal propagation, grow, and at zone of positive pressure, when acoustic pressure reaches certain value, bubble increases rapidly, then closes suddenly。And shock wave is produced when bubble closes, producing thousands of atmospheric pressure about, destroy insoluble dirt and make them be scattered in supercritical carbon dioxide cleanout fluid, when group's particle is wrapped up in by greasy dirt and is attached on cleaning part surface, oil is emulsified, solids and disengaging, thus reaching the purpose of cleaning, after cleaning, undergoing phase transition through counterbalance valve 11 blood pressure lowering with the supercritical carbon dioxide of dirt and become gaseous carbon dioxide and enter gas-tight silo 7, dirt is then still fallen into bottom separating still can be discharged by blowoff valve 10 for solidliquid mixture。After cleaning process terminates, open air bleeding valve 9 and separating still and cleaning still are carried out pressure release。Pressure release can also be opened valve and the water in chuck layer 12 is flow to separating still be rinsed by chuck layer outlet 14 after completing, gaseous carbon dioxide in separating still is circulated among supercritical carbon dioxide blood circulation by gaseous carbon dioxide outlet 15, thus ensureing equipment work seriality。
