Abstract A method of draining parts emerging from hot galvanizing baths using a range of vibration excitation frequencies capable of covering the fundamental frequencies of the parts to be drained. Three different methods are disclosed. According to a first method the vibrations are obtaining by exciting with a narrow band white noise the support for the parts to be drained. According to a second method, the vibrations are produced from a single exciter fed with narrow band white noise and energizing vibrators through the medium of amplifiers. According to a third method, the vibrations are produced by a number of small vibrators each of which furnishes one of the frequencies of the chosen spectrum, whereby said vibrators jointly synthesize the narrow band white noise. Three different means are disclosed for producing vibrations, one where the vibrators are mounted on a false lifting beam, the second where the vibrators are mounted on the lifting beam, and the third where the vibrators are enclosed in a container placed between the lifting beam and the hoisting means.
A machine for draining parts emerging from a hot galvanizing bath comprising a support structure including an elastically suspended lifting-beam; means on said beam to rigidly link a plurality of parts to be drained; vibrator means constructed and arranged with said beam to vibrate said plurality of parts; energizer means for said vibrator means including means for controlling the vibrations of said plurality of parts within a frequency range of narrow-band "white noise," the said frequency range covering the natural fundamental frequencies of said parts.
