Composite bar energy converter cleaning machine

Abstract

A compound bar transducer cleaning machine belongs to cleaning machinery. The compound bar transducer is provided with a vessel for holding liquid. The compound bar transducer and a power amplifier are connected by a conductor. The power amplifier and a signal source are connected by the conductor. The compound bar transducer consists of a duralumin front cover plate, a piezoelectric ceramics heap and a steel back cover plate. The conductor is connected with a positive electric contact and a negative electric contact of the piezoelectric ceramics heap. The utility model is able to turn electric energy into acoustic energy, thus, producing cavitation effect in water to finish clean-out operation. The utility model has advantages of simple structure, broad range of working frequency, wide application and good operation, which is especially suitable for washing the parts with gaps that are difficult to clean.

Description

technical field [0001] The invention belongs to a cleaning machine, and mainly relates to a cleaning machine for cleaning parts with a transducer converted from electrical energy into sound energy. Background technique [0002] At present, cleaning equipment that uses transducers that convert electrical energy into sound energy to clean parts with oil stains, dirt and dust has been applied in practical operations, and has brought positive effects to parts cleaning. However, due to the defects in the structural design of the transducer, the existing electric and acoustic transducer can only have a fixed operating frequency, and the frequency bandwidth is small, so the frequency cannot be changed. Oil stains, dirt and dust in the grooves and other depths are not easy to remove, which reduces the quality of work. Otherwise, multiple transducers in different frequency bands must be prepared, which increases the purchase cost and tedious cleaning operations. SUMMARY OF THE INVE...
