The embodiments described below with reference to the accompanying drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1, an embodiment of the present invention provides an ultrasonic film washing machine, which comprises a washing water tank 1, a washing water pump, and a film washing drum 8, which are connected in sequence; the membrane cleaning cylinder 8 is internally provided with a membrane component 10 to be cleaned and an ultrasonic generator 7, the membrane component 10 to be cleaned is detachably arranged in the membrane cleaning cylinder 8, and the ultrasonic generator 7 controls the wavelength of ultrasonic waves through an adjustable frequency controller so as to send the ultrasonic waves to clean the membrane component 10 to be cleaned of impurities.
In practical use, the ultrasonic film washing machine comprises a washing water tank 1 which can contain a certain amount of washing solution, and the washing solution in the water tank is conveyed out by the outlet water of the washing water tank 1 through a washing water pump; the solution filtered by the precision filter 5 enters a membrane cleaning cylinder 8 with a detachable membrane; an ultrasonic generator 7 is arranged in the cleaning cylinder, and the ultrasonic generator 7 is controlled by an adjustable frequency controller to adjust the wavelength of ultrasonic waves.

Cleaning liquid is prepared in a cleaning water tank 1, and a membrane component (namely a membrane component 10 to be cleaned) arranged in a membrane shell is cleaned after being filtered by a precision filter 5 under the action of 1-4Mpa working pressure (pressure is adjustable) through a cleaning water pump 2.

Furthermore, a 50Hz alternating current power supply is arranged in the electric control cabinet.
In practical operation, the cleaning steps can be divided into two types: 1. and 2, common cleaning and ultrasonic cleaning.

After the ultrasonic cleaning is started, the ultrasonic generator 7 converts 50Hz alternating current into an ultrasonic frequency electric oscillation signal through electrical control, and then the ultrasonic frequency electric oscillation signal is transmitted to the ultrasonic transducer through a cable. During cleaning, cavitation (namely the phenomenon that countless bubbles are quickly formed and quickly implode in the cleaning liquid) during ultrasonic cleaning is utilized, the generated impact peels off dirt on the surface of the membrane immersed in the cleaning liquid, the dirt is discharged along with the scouring action of water flow, and finally the dirt is filtered by a filter.
