The industrial-scale use of ultrasonic cleaning equipment: the technology in action

Under the influence of ultrasound of a certain intensity cavitation occurs in the liquid (occurrence and further explosion of huge number of microscopic bubbles). With the explosion of bubbles on the surface of some object immersed in the treatment solution, an enormous amount energy is released at the micro level, that leads to rapid separation of different impurities. This technology allows achieving a high degree of purification and is implemented by means of ultrasonic baths with embedded or immersed emitters. The use of ultrasound in some cases eliminates the use of chemically aggressive and environmentally harmful solutions.

The serial production largely utilises complex ultrasound washing equipment. An average system consists of nodes mounted on the modular principle, the use of which provides a broad range of technological capabilities. The nodes are combined into a mechanised or automated line of surface cleaning products after manufacturing operations. The complex is generally composed of an ultrasonic bath for cleaning, rinsing bath to finalise washing, drying chamber for transportation of clean products, automatic control and management panels.

For continuous precision cleaning of rolled products (wire, sheet, wire) a specialised ultrasonic line can be used. Cleaning and rinsing modules are fed with the washing solution and along with washing an imposition of high-power ultrasonic vibrations takes place. After washing an object is moved to a drying chamber. At the exit line, if necessary, heating of the product prior to coating, can be initiated. The line is built directly at the exit of the rolling equipment, or put to a separate production area and equipped with their own supply arrangements.

Cleaning of metal pipes from various manufacturing and operational pollution by using two sets of ultrasonic tools equipped with two channels for supplying a washing solution. Purification of the outer surface is carried out with magnetostrictive transducer from mechanical acoustical transformer of appropriate design and reflective plate on the opposite side of the pipe. Cleaning the insides of the pipe is implemented by a shell composed of an ultrasonic transmitter and an acoustic transformer converting the vibrations of the front end of the radiator into radial ones. The feed mechanism allows movement of the pipe through the nodes of cleaning the external and internal surfaces at a speed which provides the desired level of purification. At the inlet an induction heater can be installed for softening the oil and wax deposition.

To maintain cost savings and environmental procession improvement such systems can carry a variety of filtration systems and regeneration of process solutions. To supply washing modules with distilled water an industrial distiller can be used. With the advent of the technology and emergence of such innovating companies as Hilsonic, focusing on ultrasonic cleaner equipment manufacturing, the cost-efficiency of the cleaning method is pushing the use of ultrasonic cleaning equipment closer to medium and small enterprises; an obvious economical feasibility is confirmed by leasing opportunities manufacturers have started to offer.
