Wherein, the air knife water blowing device is arranged on the water blowing tank 7; the air knife water blowing device comprises an air knife K-3 and a high-pressure fan. In this embodiment, preferably, two air knives K-3 are symmetrically disposed at two sides in the water blowing tank 7 and are used for simultaneously blowing water to two sides of the workpiece in the water blowing tank 7, and the air knives K-3 are connected with the air outlet pipeline of the high-pressure fan, so that the water blowing efficiency and effect can be improved by times due to the symmetrical arrangement. The specific structure of the air knife K-3 can adopt the prior art, so that the detailed description is omitted.

Specifically, the wind pressure of the high-pressure fan is 30kPa-100Kpa.

Wherein, the hot air drying groove 8 is provided with a hot air blower K-4. In this embodiment, four air blowing openings 8-1 are uniformly arranged in the hot air drying groove 8 along the circumferential direction; the outlet of the air heater K-4 is connected with the four air blowing openings 8-1 through an annular pipeline 8-2.

Preferably, the annular duct 8-2 is made of a heat insulating material.

Specifically, the specific structure of the air heater K-4 may be a related art, so that details are not repeated.

The utility model can complete the following new cleaning procedures of the workpiece (box-type workpiece): ultrasonic degreasing, ultrasonic washing, heating washing I (70-80 ℃), heating passivation (35 ℃), normal temperature washing II, heating washing III (70-80 ℃), water blowing and hot air drying.

In the ultrasonic degreasing process, the degreasing cleaning solution (for example, a certain proportion of degreasing cleaning solution is heated in clear water) is arranged in the ultrasonic degreasing tank 1, and a workpiece is placed in the ultrasonic degreasing tank 1, and the liquid level of the degreasing cleaning solution needs to be above the workpiece. The cavitation of the ultrasonic wave is physical, while the ultrasonic wave degreasing combines chemical action and physical action. Firstly, the oil removing cleaning liquid is used for penetrating and dissolving dirt, and then the dirt layer on the surface of the object is peeled, dispersed and emulsified by the impact force generated by the cavitation of ultrasonic waves, so that the dirt separated from the surface of the object is prevented from being reattached to the object.

In the ultrasonic washing process, clean water is arranged in the ultrasonic washing tank 2, and because the ultrasonic wave has a strong effect of penetrating through solids, the ultrasonic wave can penetrate through the other side surface of the washed object, and all inner cavities, blind holes and slits immersed in a medium, dirt attached to the surface of the washed object is peeled off, so that a perfect washing effect is achieved. Because the ultrasonic vibration propagates in the liquid, when the sound wave pressure reaches one atmosphere, the power density of the ultrasonic wave is about 0.35W/cm < 2 >, and the peak value of the sound wave pressure of the ultrasonic wave propagating in the liquid can easily reach vacuum or negative pressure; however, there is virtually no negative pressure, and thus a large force is generated in the liquid, pulling the liquid molecules apart into a cavity (cavitation nucleus), which is a vacuum or very near vacuum, which is at its maximum at the next half cycle of the signal voltage (or ultrasonic pressure). The liquid molecules are crushed due to the increase of the ambient pressure, and the liquid molecules are strongly collided to generate very strong impact force, so that dirt on the surface of the cleaned object is impacted, and the phenomenon that impact waves are generated when countless tiny and dense bubbles break is called cavitation. This cavitation is very likely to occur at the interface of the solid and liquid and thus has an extraordinary cleaning effect on objects immersed in the liquid under ultrasonic action. In addition, because the ultrasonic wave has a strong effect of penetrating through the solid, the ultrasonic wave can penetrate through the other side surface of the cleaned object, and all the inner cavities, blind holes and slits immersed in the medium, the dirt attached to the surface of the cleaned object is peeled off, and a perfect cleaning effect is achieved. Meanwhile, the ultrasonic wave has the emulsification and neutralization effects, so that the cleaned oil stains can be more effectively prevented from being reattached to the cleaned object. Therefore, the cavitation can clean the inner and outer surfaces (such as the box body) of the object immersed in the liquid under the ultrasonic wave action, which is an important aspect of ultrasonic cleaning over other cleaning means.

In the step of heating and washing I (70-80 ℃), clean water is arranged in the first heating and washing tank 3 and heated to 70-80 ℃ and the temperature is kept stable; the degreasing cleaning agent can be removed, and impurities are further cleaned, so that the surface of a workpiece is clean after cleaning, and preparation is made for subsequent high-quality passivation;

in the heating passivation (35 ℃) process, the passivation solution is arranged in the heating passivation tank 4 and heated to 35 ℃ and the temperature is kept stable; the surface of the workpiece is clean after cleaning, is very activated and is easy to be corroded, and the cleaned metal surface can be provided with a protective film by passivation immediately, so that the corrosion is slowed down. The passivation is set at the optimal temperature of 35 ℃, so that the solution temperature is slightly increased to reduce the passivation time, and the problems of blacking, incapacitation, mist display and the like of the passivation film caused by overhigh temperature are avoided.

In the normal temperature water washing step II, clear water is arranged in the normal temperature water washing tank 5, so that passivation solution on the workpiece can be removed;

in the step of heating and washing III (70-80 ℃), the second heating and washing tank 6 is provided with clean water and is heated to 70-85 ℃ and the temperature is kept stable; the refractory passivation solution components possibly remained on the workpiece can be completely removed, and the complete absence of residues can be ensured;

during the water blowing process, the workpiece in the second heating water washing tank is subjected to air cutting and water blowing through the air knife water blowing device K-3, so that the cleaning water of the workpiece can be blown off, and the cleaning cleanliness is improved; the workpiece surface is only left with a thin layer of residual water, and the subsequent hot air drying process can effectively shorten the drying time, improve the drying efficiency, reduce the drying energy consumption, improve the cleanliness, improve the cleaning efficiency and reduce the running cost.

During the hot air drying process, the hot air blower K-4 simultaneously performs hot air drying on the workpiece in the hot air drying groove 8 in four directions through the four air blowing openings 8-1, so that high-efficiency omnibearing circumferential drying can be realized, and the workpiece is not required to be overturned. Since the outlet of the air heater K-4 is connected with the four air blowing openings 8-1 through the annular pipeline 8-2. Compared with the four air heaters K-4, the scheme only needs a single air heater K-4 to realize the hot air drying of the workpiece in the hot air drying groove 8 in four directions, so that the energy is saved, the efficiency is improved, the equipment and the use cost are reduced, in addition, the annular pipeline 8-2 is made of heat insulation materials, the heat loss can be reduced, the scalding prevention is realized, the safety is realized, and the energy is saved.

Preferably, the air blowing opening is horn-shaped, so that the diffusion area of air can be enlarged, the quick drying of workpieces with larger shapes is facilitated, and the phenomenon that dead areas cannot be blown is reduced.

Therefore, the utility model can integrate multiple processes into a whole, so as to meet the requirement of utilizing limited cleaning space, completing multiple stations and multiple-process cleaning in turn in the shortest cleaning time, and achieving the combined effects of more reasonable process, better cleaning effect, very stable cleaning degree, shorter period, lower cost and the like;

In operation, since the hanging basket 11 is suspended on the hanging conveyor and the workpieces are placed in the hanging basket 11, the hanging basket 11 and the workpieces therein can be driven by the lifting driving cylinder 10 to descend and enter the working tank (namely, any one of the ultrasonic wave oil removal tank 1, the ultrasonic wave water washing tank 2, the first heating water washing tank 3, the heating passivation tank 4, the normal temperature water washing tank 5, the second heating water washing tank 6, the blowing water tank 7 or the hot air drying tank 8) (see fig. 5), meanwhile, the hanging basket 11 and the workpieces therein can be driven by the lifting driving cylinder 10 to ascend and then leave the working tank and reach a high position, and then can be driven by the hanging conveyor to be conveyed to the working tank of the next adjacent process (namely, any one of the ultrasonic wave oil removal tank 1, the ultrasonic wave water washing tank 2, the first heating water washing tank 3, the heating passivation tank 4, the normal temperature water washing tank 5, the second heating water washing tank 6, the blowing water tank 7 or the hot air drying tank 8) (see fig. 4), and then, and circulate.
