Description
Technical Field
The invention belongs to the field of clothes cleaning, and relates to a clothes cleaning device based on an ultrasonic cavitation effect.
Background
The ultrasonic washing work is mainly completed by cavitation bubbles on the surface and nearby the clothes. The physical mechanism can be attributed to ultrasonic cavitation, shock waves, micro-acoustic flow, micro-jet flow generated along with the cavitation and the mechanical effect of ultrasonic vibration of the cleaning liquid. On one hand, the washing effect of the micro-acoustic flow generated by ultrasonic cavitation and the impact effect of high-speed micro-jet generated on a solid-liquid interface destroy the adsorption of dirt to clothes; on the other hand, ultrasonic cleaning provides a new dissolution mechanism on the surface of clothes, so that grease is emulsified and dirt is dissolved. Mainly expressed by the following four points:
1) micro bubbles (cavitation core) in the cleaning liquid (such as water) vibrate under the action of a sound field, when sound pressure reaches a certain value, the bubbles rapidly grow and then suddenly close, and shock waves generated by closing the bubbles can instantly form pressure reaching thousands of atmospheric pressures around, so that stubborn stains on the clothes are destroyed, and the stubborn stains are separated from the clothes and dispersed in water. Repeated impact of the steam type cavitation on the dirt layer not only destroys the adsorption of the dirt layer on the clothes, but also causes fatigue damage of the dirt layer to make the dirt layer separate from the surface of the clothes. For solid particles wrapped by oil stains, the oil and water are quickly dispersed and emulsified at an interface under the action of ultrasonic cavitation, and the solid particles are separated immediately. The air type air bubble vibration cleans the surface of the clothes, once the dirt layer has gaps, the air bubbles can penetrate into the dirt layer to vibrate, and the dirt layer falls off.
2) Cavitation bubbles will accompany a series of second order phenomena, such as radiation twisting, during oscillation. In a homogeneous liquid, the circular flow caused by the radiation torsion acting on the liquid itself is called acoustic flow. The sound stream of the mum level is the micro sound stream. The micro-acoustic flow can cause high speed gradient and viscous stress to exist on the surface of the pulsating bubble, and the high speed gradient and the viscous stress are enough to destroy dirt on the surface of the clothes to enable the dirt to be removed.
3) The high-speed micro-jet generated by ultrasonic cavitation on the solid-liquid interface can remove or weaken the boundary dirt layer, enhance the stirring effect, accelerate the dissolution of soluble dirt and strengthen the cleaning effect of the chemical cleaning agent.
4) The ultrasonic vibration of the cleaning fluid itself does not contribute negligibly to the cleaning. Such as 20kHz, 2W/cm2When the ultrasonic wave of (2) is propagated in the cleaning liquid, it will cause the vibration displacement amplitude of the mass point to be 1.32 μm, the speed to be 0.16m/s, and the acceleration to be 2.04 x 104m/s2Sound pressure of 2.45 x 105Pa. This indicates that the soil layer on the surface of the laundry will be subjected to 2 ten thousand violent impacts of the cleaning liquid from positive 2.45 atmospheres to negative 2.45 atmospheres per second. This is the result of the traveling field calculation, and in fact, the closer to the reverberant field in the cleaning tank, may make this process more drastic.
However, the existing ultrasonic cleaning device has the problems of small coverage after ultrasonic emission, small water flow mixing capability, low intensity of cavitation effect, unsatisfactory cleaning effect and the like.

In the scheme, a rubber sealing gasket, a top cover 1 corrosion lining for corrosion prevention of the container, a container corrosion-resistant lining and a bottom corrosion-resistant lining are arranged in the cleaning device based on the ultrasonic cavitation effect. These liners may be constructed using weld overlay. These liners are primarily water resistant and also provide the benefit of reflecting as much ultrasound as possible.

The main container 2 can be made of common corrosion-resistant materials, such as austenitic stainless steel 316 and the like, so that the cost of the device is effectively reduced. In order to enhance the washing effect, the helical blades 11 of the device drive the fluid to circularly flow when the device is in operation. Meanwhile, in order to save water, the flow does not need to add extra water repeatedly like a common washing machine, and the clothes can be washed circularly only by circulating the water added at the beginning between the circulating water inlet 12 and the circulating water outlet 13. When the water-saving washing machine works, water flow passes through the small holes 8 of the screen plate, and can generate mixing at the small holes 8 of the screen plate, so that the washing effect is enhanced, and certain insoluble particles are not easy to deposit.

Meanwhile, the arrangement of the ultrasonic waves in 2 × 2 also enables the ultrasonic waves to cover the cleaning portion in the entire container.
The working flow of the device of the invention is as follows:
firstly, the objects to be cleaned are arranged in the main container 2, the water required is injected from the water injection port 14, a certain amount of washing powder or washing liquid is poured in, the top cover 1 is closed, and the power supply is turned on. Then, the helical blades 11 in the cladding 3 on the two side surfaces of the main container 2 will start to rotate first, so as to drive the water originally standing in the main container 2 to circulate the water flow. At the same time, the ultrasonic transducers 5 on both sides start to operate to emit ultrasonic waves. The molecules and insoluble particles of the dirt originally attached to the surface of the cleaned object can be separated from the surface of the cleaned object under the action of the ultrasonic waves and the flowing water and flow together with the water flow. After the cleaning operation is finished, the power supply is turned off, the spiral blade 11 stops rotating, the water outlet 15 is opened, and the sewage in the container can automatically flow out from the water outlet 15.
After accounting, the power consumption of the device of the invention is about 70% of that of the conventional washing machine under the same condition, and the water consumption of unit cloth is about 63% of that of the conventional washing machine.
