step c: putting a workpiece 100 containing a plurality of pollution layers such as paint, oil stain, oil sludge, carbon deposit and the like into a first tank 1, and starting molten salt ultrasonic composite cleaning;
step d: after the reaction of the pollution layer on the surface of the workpiece 100 is finished, the workpiece is lifted out, cooled and then lifted into the second tank 2 for rinsing; when the rinsing is completed, the workpiece 100 is transferred to the next process;
step e: and (d) repeating the steps c and d, and along with the increase of the number of the cleaning workpieces and the service time, the cleaning liquids in the first tank 1 and the second tank 2 are gradually turbid, and the cleaning liquids need to be regularly treated with high efficiency and low cost.
Step f: when the turbidity of the rinsing liquid in the second tank 2 exceeds a preset turbidity value, automatically starting a rinsing liquid recycling system to remove impurities in the rinsing liquid; when the pH value of the rinsing liquid in the second tank 2 is more than or equal to 9, the pH adjusting medium storage 4 is opened, and CO is introduced into the second tank through the conveying pipeline 4012A gas or an acid liquid,neutralizing the alkalinity of the rinsing liquid in the second tank 2 to produce carbonate; when the pH value of the rinsing liquid in the second tank 2 is approximately equal to 7, the introduction of CO is stopped2The gas or the acid liquid realizes zero emission of the rinsing liquid in the second tank 2, and low cost and recycling of the cleaning liquid are achieved.
Step g: when the turbidity of the molten salt in the first tank 1 exceeds a preset turbidity value, the high-temperature molten salt bath recycling system is lifted from the first tank 1 by 20cm high from the molten salt liquid level through the iron sling chains and stays in the air for 1min to 2min, so that the molten salt liquid in the collecting tray 3 flows out and is drained, and then the molten salt liquid is lifted out and placed in the salt deposition tray, so that the high-temperature molten salt bath in the first tank 1 is efficiently, low-cost and continuously recycled, namely, the high-temperature molten salt is nearly subjected to zero emission.
Step h: the collecting plate 3 is detached from the high-temperature molten salt bath recycling system, internal sediments are cleaned, the sediments are delivered to a third party with professional qualifications for resource treatment, then industrial salt is supplemented into the first tank 1, the high-temperature molten salt bath recycling system is hung into the first tank 1 again, and continuous work of the first tank 1 without stopping is achieved.
Based on the description of the above embodiments, the molten salt ultrasonic cleaning device and the operation method thereof provided by the embodiments of the present disclosure have at least the following beneficial effects:
1) recycling the high-temperature molten salt bath: along with going on in batches work piece cleaning process continuously, impurity such as remaining sand after the reaction of work piece surface pollutant, dirt, metal oxide constantly sinks into the tank bottom of first groove 1 by gravity, cause the fused salt in first groove 1 to be turbid, work piece cleaning quality descends, through the high temperature molten salt bath cyclic utilization system that this disclosed embodiment provided, utilize collecting tray 3 to regularly collect fast on line and clear up the precipitate of the tank bottom of first groove 1, in time ensure the cleanness of high temperature fused salt, need not to carry out secondary complex processing through the extra-tank emission, the cyclic utilization of high temperature fused salt has been realized.
2) Zero discharge of neutral rinsing liquid: because the workpiece to be cleaned is continuously taken out of the high-temperature molten salt alkaline oxide and impurities from the first tank 1, the neutral rinsing liquid in the second tank 2 is turbid and alkaline, the cleaning quality of subsequent working procedures of the workpiece is influenced, and the rinsing waste liquid is environment-friendly after being dischargedThe treatment cost is high, and the rinsing liquid recycling system provided by the embodiment of the disclosure utilizes the filter 6 and fills CO2The gas neutralizes the alkaline rinsing liquid, so that the rinsing liquid can be washed and recycled, and the effects of zero discharge of the rinsing liquid and carbon utilization are achieved.
3) The service life of the molten salt heating pipe is greatly prolonged: because treat impurity such as cleaning workpiece surface paint, heavy greasy dirt and silt are thick and heavy, the tank bottom precipitate of first groove 1 gathers rapidly, very easily covers the heating pipe, leads to the heating pipe dry combustion fragile, influences belt cleaning device heating effect and reliability, through the high temperature molten salt bath cyclic utilization system that this disclosed embodiment provided, can reduce heating pipe surface silt coverage degree, prevents that the heating pipe from dry combustion, promotes heating pipe life.
4) The cleaning device has high reliability: the bottom of the first tank 1 is designed into a totally-enclosed structure, and complex structural designs such as a salt discharge valve, a stirrer and a condenser are not needed, so that the risk of leakage of high-temperature molten salt is reduced, and the reliability of the cleaning device is improved.
Based on the embodiments of the invention described above, the technical features of one of the embodiments can be advantageously combined with one or more other embodiments without explicit negatives.
