Description

Input type ultrasonic cleaning system

Technical Field

The invention relates to the technical field of cleaning equipment, in particular to a throw-in vibration plate type ultrasonic cleaning system comprising a sewage treatment system.

Background

Ultrasonic cleaning is a process in which ultrasonic waves are converted into high-frequency mechanical oscillations (ultrasonic waves) by an ultrasonic transducer and transmitted into a medium (cleaning liquid), the radiation of the ultrasonic waves in the cleaning liquid vibrates the liquid to generate tens of thousands of micro-bubbles, the micro-bubbles are generated and grow in a negative pressure region formed by the longitudinal transmission of the ultrasonic waves and are rapidly closed in a positive pressure region, and in the process called cavitation effect, instantaneous high pressure exceeding 1000 atmospheres is generated when the micro-bubbles are closed. The continuous instantaneous high pressure impacts the article like a series of small bombs to make the dirt on the surface and in the gap of the article fall off quickly, so as to clean the article. If the cleaning agent is added into the cleaning liquid, under the vibration action of ultrasonic waves and chemical reaction, oil stains and dust inside and outside the workpiece (radiator) can be rapidly and thoroughly cleaned.

Ultrasonic cleaning has many advantages, for example, ultrasonic cleaning machines are particularly suitable for workpieces 4 with complex shapes and structures; no matter how complex the shape of the workpiece is, the ultrasonic cleaning effect can be achieved as long as the workpiece is placed in the cleaning liquid and can contact with the liquid. The ultrasonic cleaning machine has remarkable cleaning effect on workpieces which cannot be cleaned completely and effectively by manual cleaning and other cleaning modes, can thoroughly meet the cleaning requirement and remove stains at dead angles of complex workpieces. Based on the above advantages, ultrasonic cleaning apparatuses are widely used.

However, in the ultrasonic cleaning apparatus for industrial production in the prior art, the cleaning tank is generally small in size, the amount of workpieces to be processed at one time is limited, and meanwhile, workpieces with the length of five meters cannot be cleaned basically. The size of the cleaning tank is enlarged blindly, which causes the problem that the local cleaning effect is not ideal. In addition, the waste liquid treatment that ultrasonic cleaning equipment among the prior art produced is puzzled the vast user all the time, because the waste liquid that produces can't in time effectively handle, very big restriction ultrasonic cleaning's application popularization.
