Definitions
- This invention relates generally to tanks for ultrasonic processing, and relates more particularly to a reflective structure added to a tank to improve reflection and decrease absorption of ultrasonic energy by the tank.
- Ultrasonic cleaning processes typically use metal tanks that contain a liquid and parts to be cleaned. Ultrasonic energy is supplied to the tank by ultrasonic transducers, which may be attached to or immersed in the tank.
- the walls and floor of the tank are typically 0.25 inch or 8 gauge or 10 gauge stainless steel. The walls and floor of the tank absorb some of the ultrasonic energy produced by the ultrasonic transducers, which decreases the amount of ultrasonic energy that can be employed in the cleaning processes.
- ultrasonic vibrations used to excite liquids bounce off metal if there is air on the other side of the metal and the metal is relatively thin. For example with air on the other side of 14 gauge steel, ultrasonic activity has been measured to bounce off nine times more effectively than with 0.25 inch steel. The ultrasonic vibrations are reflected rather than absorbed by a thin metal panel backed with air. However, it is not practical to fabricate tanks out of 14 gauge metal because relatively thicker materials are needed for structural integrity and durability.
- the present invention is an air blanket reflector that is placed inside an ultrasonic tank, at or near the walls of the tank, for reflecting ultrasonic energy.
- the air blanket reflector has a relatively thin metal plate, such as 14 gauge stainless steel, facing the interior of the tank and an air-filled cavity on the opposite side of the thin metal plate.
- the invention is a processing apparatus that includes (1) a tank for containing a liquid and one or more parts to be processed, where the tank has one or more walls; (2) one or more ultrasonic transducers for providing ultrasonic energy to the interior of the tank; and (3) an air blanket reflector located adjacent to one or more walls of the tank.
- the air blanket reflector includes a face panel oriented toward the interior of the tank and a cavity containing no liquid located between the face panel and the wall of the tank. The thickness of the face panel is less than the thickness of the walls of the tank.
- Figure 1 is a sectional view of a corner of a tank with a fixed air blanket reflector according to the invention.
- Figure 2 is a perspective view of a tank with air blanket reflectors attached to or mounted at the walls of the tank.
- Figure 3 is a sectional view of a corner of a tank with a removable air blanket reflector according to the invention.
- Figure 4 is a sectional view of the removable air blanket reflector.
- Figure 5 is a perspective view of the removable air blanket reflector.
- Figure 6 is a perspective view of the removable air blank reflector shown in section.
- An air blanket reflector is a structure that is placed inside an ultrasonic tank, at or near the walls of the tank.
- the air blanket reflector has a relatively thin metal panel, such as 14 gauge (0.0781 inch) stainless steel, facing the interior of the tank and a cavity or pockets filled with air on the opposite side of the thin metal panel.
- the air blanket reflector 14 is attached to a wall 10 of a tank 12 under the surface 20 of liquid in the tank.
- the air blanket reflector 14 has a metal panel 16, preferably composed of 14 gauge stainless steel.
- the edges of the metal panel 16 have flanges 18 that are attached to the tank wall 10, forming a cavity 22 between the metal panel 16 and the tank wall 10.
- the cavity is preferably about 0.25 to 0.375 inch in depth between the inside of the metal panel 16 and the tank wall 10.
- the flanges 18 of the air blanket reflector 14 are preferably welded to the tank wall 10 around all sides of the reflector.
- the metal panel 16 of the air blanket reflector 14 reflects ultrasonic vibrations back into the interior of the tank better than the thicker tank wall, which tends to absorb the ultrasonic vibrations.
- the tank walls are preferably 0.25 inch or 8 gauge (0.1719 inch) or 10 gauge (0.1406 inch) stainless steel.
- the air blanket reflector should cover a significant portion of the side walls of the tank in order to efficiently reflect ultrasonic vibrations that would otherwise be absorbed by the tank walls.
- the air blanket reflector may also be used near the bottom of the tank to reflect ultrasonic vibrations that would otherwise be absorbed by the bottom.
- the air blanket reflector is most useful when the ultrasonic vibrations are generated inside the tank, such as with rod type transducers that are immersed inside the tank.
- the air blanket reflector can also be used with transducers mounted on a surface of the tank, such as the bottom or a side wall, in which case an air blanket reflector would not be mounted adjacent to that surface.
- the cavity behind the metal panel of the air blanket reflector is preferably filled with unpressurized air and is sealed so that the liquid inside the tank does not enter the cavity.
- gases such as nitrogen, for example, could be used instead to fill the cavity.
- the illustrated embodiments of the air blanket reflector show the reflector to be under the surface of the liquid, the reflector could extend upward above the level of the liquid and could provide venting at the top of the cavity. What is important is that there is air or another gas inside the cavity. Since the cavity needs to be filled with a gas for the reflector to operate properly, any liquid inside will reduce the effectiveness of the reflector and should be avoided.
- FIG. 3-6 Another embodiment of the air blanket reflector, as shown in Figures 3-6, is an air blanket reflector 30 that hangs inside the tank 12 near the tank wall 10 under the surface 20 of liquid in the tank.
- the air blanket reflector 30 has two metal panels, 32 and 34, and perimeter walls 36 that form a sealed cavity 38, preferably containing air.
- Preferably at least the outer metal panel 32 of the air blanket reflector 30 is composed of 14 gauge stainless steel.
- the cavity 38 is preferably about 0.25 to 0.375 inch in depth between the inside surfaces of the metal panels 32 and 34.
- Internal ribs 40 may be used inside the cavity 38 for supporting the metal panels.
- the internal ribs 40 are spaced apart, preferably by about 12 inches, and divide the cavity 38 into several pockets 42, as shown in Figure 4.
- the air blanket reflector can be fabricated from flat plates by welding.
- Mounting brackets 44 are used to mount the air blanket reflector 30 inside a tank.
- Preferably, four brackets 44 are used at the corners of the air blanket reflector 30 to anchor it to the bottom or wall of the tank.
- Figure 6 is a perspective view of the air blanket reflector 30 similar to Figure 5, but the metal faces 32 and 34 are shown in section. Since this embodiment of the air blanket reflector is mounted with brackets, it is easier to remove from the tank than the embodiment shown in Figures 1 and 2, which is welded to the tank.
- the ultrasonic air blanket reflector In applications using rod-type ultrasonic transducers with powerful low frequency thickness mode ultrasonics, use of the ultrasonic air blanket reflector has the advantage of 14 gauge metal for reflecting sound but the strength of thicker metals, e.g., 10 and 8 gauge stainless steel or even stronger 0.25 inch stainless steel, for an effective tank.
- the air blanket reflector is useful for ultrasonic applications such as cleaning heat exchangers in refineries, cleaning dairy equipment, cleaning pulp processing equipment, and for pharmaceutical applications. Additionally the same technology can be used for cleaning automobile and truck frames, large motors, oil and gas drilling tools and other large objects.
- the invention is relatively inexpensive and simple to manufacture.
