Design of an Ultrasonic Cleaner

Project Overview

Ultrasonic cleaning is used to clean submerged items (into water or special solvent) restore the items back into their original state by using ultrasound. The frequency used in ultrasound varies between 20 to 400 kHz. The duration of the cleaning process is usually between three and six minutes but could take up to 20 minutes depending on the item to be cleaned. This ultrasonic method can be used to clean in various items like tools, jewelry and industrial parts such as pipes, heat exchangers, valves and filters or even in dental cleaning. The estimated components needed for the project should be power source, signal generator (possible with amplifier), transducer and mechanical set-up. In ultrasonic cleaning there is no need to disassemble the part to be cleaned. Ultrasonic cleaning uses cavitation bubbles induced by high frequency pressure (sound) waves to agitate a liquid. It can remove dust, dirt, oil, pigments, rust, grease, algae, fungus, bacteria, polishing compounds, fingerprints, soot wax and mold release agents, and so on.
The practical goal of this project is the design and the manufacture of a working prototype of an ultrasonic cleaner. Also the project envisage the testing of the prototype for different tasks such as cleaning of car parts, jewelry and corrosion.

Project Objectives

  • Design an ultrasonic cleaning machine that can clean items in an efficient way.
  • Design a prototype ultrasonic cleaner.
  • The machine can save time and money also easy to move and carry.
