Abstract

DC60 The cleaning fluid flow path has been formed to provide the cleaning fluid The clean in the cleaning tank is vacuumed by a circulation pump. And has been circulating through the path Pre-set and then returned to the cleaning tank again, an air ejection device for dissolving air in the cleaning liquid, foaming by cavitation. Cleaning fluid has been placed on the path of the flow path to allow air Dissolved in the cleaning fluid that passes through the circulating path, the cleaning fluid forms a foam. By ejection device And the dissolved air that forms foaming will return to the tank of ready cleaning With the cleaning fluid so that the foaming dissolved air is expelled from the liquid surface. Of the cleaning tank to the outside of the tank.Furthermore, an impeller-type pump is used as a circulation pump and the dissolved air concentration of the cleaning liquid is regulated to the range of 2.5 to 3.5 mg / L. The cleaning fluid flow path has been formed to allow the cleaning fluid to The clean in the cleaning tank is vacuumed by a circulation pump. And has been circulating through the path Pre-set and then returned to the cleaning tank again, an air ejection device for dissolving air in the cleaning liquid, foaming by cavitation. Cleaning fluid has been placed on the path of the flow path to allow air Dissolved in the cleaning fluid that passes through the circulating path, the cleaning fluid forms a foam.

Disclaimer (all) which will not appear on the advertisement page: EDIT 10/7/58 1. Ultrasonic cleaning equipment incorporating a cleaning tank that It is fixed by an ultrasonic generator for the ultrasonic cleaning of the object that is Will be cleaned by submerging the object to be cleaned in the said cleaning tank at Has been contained with cleaning liquid And supersonic radiation from wave generators Above the sound, where the cleaning fluid flow path is formed in such a way that the liquid Cleaned in such cleaning tank was vacuumed by a distant recirculation pump and was made It circulates through a predetermined path and then it is fed back into the cleaning tank again and the ejection device is connected on the path of the fluid circulation path. Such cleaning and the air dissolve in the cleaning fluid that flows through the cleaning fluid circulation path. Such cleanliness has been foamed by the aeration device. And the air melted at The foaming will flow back into the cleaning tank with the cleaning liquid. Which makes air The foaming melt is excreted from the liquid surface of the cleaning tank to the outside of the tank. The aforementioned ejector devices are included as well. Flow channels with a constant internal cross-sectional area In which the cleaning fluid passes through it and a barrier arranged in such a flow channel with a constant internal cross-sectional area where turbulent flow is formed by resistance by such a barrier. Continued the flow of Cleaning fluid flowing through the flow channel And a hollow formation has been formed in the back of the obstruction. This causes the dissolved air in the cleaning liquid to be foaming. Impeller type pumps are used as such circulation pumps. And the dissolved air concentration of The cleaning fluid is regulated in the range of 2.5 to 3.5 mg / L and the foaming formed in the cavity is sheared by a rotating impeller. Of the circulation pump for micro-foaming in the cleaning fluid; 2. Supersonic cleaning equipment according to claim 1, where the barrier is placed in the center of the flow channel. 3. The ultrasonic cleaning device according to claim 1 or 2, where the air supply path with variable valve opening level is connected on the end. Drive device current Air out there To be able to supply air to the cleaning fluid flowing through the path. This means that the cleaning fluid can be circulated through such a supply path. 4. The ultraviolet cleaning device according to Clause 1 to 3, where the cleaning fluid inlet in the cleaning fluid circulation path. Such clean has been Make an opening on the upper part of the tank wall of the cleaning tank And the liquid discharge channel is made Cleanliness has been opened on the bottom part of the tank wall, on the opposite side of the suction hole. The cleaning fluid in the cleaning tank has been changed by The flow of cleaning fluid is changed by the control of the pump. It circulates in such a way that the dissolved air concentration in the cleaning tank is uniform. ------------------------------ --------------- 1.Ultrasonic cleaning equipment incorporating a cleaning tank that It is fixed by a supersonic wave generator for supersonic cleaning of objects that are Will be cleaned by submerging the object to be cleaned in the cleaning tank Has been contained with cleaning liquid And supersonic radiation from wave generators Above the sound, where the cleaning fluid flow path is formed in such a way that the liquid Cleaned in such a cleaning tank was vacuumed by a circulation pump and was It is circulated through a pre-defined path and then returned to the cleaning tank again and the ejector device is connected on the path of the fluid flow path. Such cleaning and the air dissolve in the cleaning fluid that flows through the cleaning fluid circulation path. The cleaner is foaming by the aeration device. And the air melted at The resulting foam will flow back into the cleaning tank with the cleaning liquid. Which makes air The foaming melt is excreted from the liquid surface of the cleaning tank to the outside of the tank. The aforementioned ejector devices are included as well. Flow channels with a constant internal cross-sectional area In which the cleaning fluid passes through it and a barrier arranged in such a flow channel with a constant internal cross-sectional area where turbulent flow is formed by resistance by such a barrier. Continued the flow of Cleaning fluid flowing through the flow channel And a hollow formation has been formed in the back of the obstruction. This causes the air to dissolve in the cleaning liquid to be foaming. The puck type pump is used as such a circulation pump. And the dissolved air concentration of The cleaning fluid is regulated in the range of 2.5 to 3.5 mg / L and the foaming formed in the cavity is sheared by a rotating impeller. Of the Kang-said circulation pump for micro-foaming in cleaning fluids. 2. Ultrasonic cleaning device according to claim 1, where such barrier is placed in the center of the flow channel with a fixed internal cross-sectional area. 3. An ultrasonic cleaning device in accordance with claim 1 or 2, where an air supply path with a variable valve opening level is connected on the current end of the drive device. Air out there To be able to supply air to the cleaning fluid flowing through the path. Circulates the cleaning fluid through the aforementioned air supply method. 4. Any of the supersonic cleaning devices in claim 1 to 3, where the suction inlet in the cleaning fluid flow path is Make an opening on the upper part of the tank wall of the cleaning tank And the liquid discharge channel is made Cleanliness has been made open on the lower part of the tank wall on the house in contrast to the suction hole. 5. Ultrasonic cleaning equipment according to any of Clause 1 to 4, where the flow of cleaning fluid in the cleaning tank is altered by: The flow of cleaning fluid is changed by the control of the pump.
