Degassing apparatus and ultrasonic wave washing apparatus using the same

Abstract

A cleaning-liquid circulation path (7) is formed so that cleaning liquid in a cleaning tank (1) is suctioned by a circulating pump (8) and circulated through a predetermined path and then, returned to the cleaning tank again. A deaeration device (9) for bubbling dissolved air in the cleaning liquid by cavitation is connected on the way of the cleaning-liquid circulation path so as to bubble the dissolved air in the cleaning liquid flowing through the cleaning-liquid circulation path by the deaeration device, and the bubbled dissolved air flows back to the cleaning tank together with the cleaning liquid so that the bubbled dissolved air is ejected from the liquid surface of the cleaning tank to the outside of the tank. Moreover, a propeller-type pump is used as the circulating pump, and the dissolved air concentration of the cleaning liquid is controlled within a range of 2.5 to 3.5 mg/l.

Description

technical field [0001] The present invention relates to a degassing device for removing dissolved air in cleaning liquid and an ultrasonic cleaning device using the degassing device. Background technique [0002] In industrial cleaning equipment, how to cleanly remove stains, burrs, etc. adhering to parts or parts for processing is an important issue. Conventionally, an ultrasonic cleaning device has been used as one of such cleaning devices. [0003] The ultrasonic cleaning device is to install an ultrasonic generator in a cleaning tank filled with cleaning liquid, and radiate ultrasonic waves to the object to be cleaned immersed in the cleaning liquid, and the vibration energy of the ultrasonic wave will remove the stains or stains attached to the surface of the object to be cleaned. Glitch etc. [0004] However, in the case of this ultrasonic cleaning device, it is known that the sound pressure of ultrasonic waves, that is, the vibration energy of ultrasonic waves, is g...

Problems solved by technology

[0007] However, the above-mentioned conventional membrane degassing device has the following disadvantages: the degassing membrane is expensive, so the cost of the device is relatively high. In addition, the degassing membrane is replaced at regular intervals, or backwashing requires maintenance and management of the device. cost and labor

However, each of these devices has its own advantages and disadvantages, and it is not a device that can satisfy degassing efficiency, cost, and device maintenance and management at the same time.
