Description

An ultrasonic hair washing device and its application

technical field

The invention relates to a treatment device and application for washing wool by ultrasonic technology. It is mainly used for the cleaning of raw animal wool such as wool.

Background technique

Ultrasonic cleaning is a method of applying ultrasonic vibration to the cleaning liquid to cause the liquid to produce a "cavitation effect", and a large number of tiny bubbles generated will generate mechanical impact on the surroundings to remove impurities, dirt or greasy on the surface of the object. Therefore, ultrasonic waves have been widely used in the cleaning of mechanical parts. Ultrasonic cleaners have been used in industry for many years as a powerful means of cleaning containers, dispersing substances in liquids, promoting chemical reactions, etc. Because currently wool spinning mills need to use multiple washing tanks for multiple washings to complete the washing process of wool raw wool, the energy consumption and water consumption are particularly large, which does not meet the requirements of energy saving and water saving. Ultrasonic vibration can promote the separation and shedding of impurities in raw wool, improve cleaning efficiency, reduce energy consumption and water consumption, and is a new type of wool washing technology that saves energy and reduces emissions.

Preliminary research has found that ultrasonic waves can be used to increase the reaction rate, reduce the scouring time and dyeing time in the dyeing and finishing process, and improve the whiteness of the fabric. Ultrasound can also improve a variety of textile processing processes and has the ability to affect a variety of wet processes. Ultrasound can alter the desizing, scouring, bleaching, dyeing, finishing and washing processes. Its use in wet processing can reduce processing time, reduce chemical consumption and energy and water consumption, and improve product quality. However, due to the influence of the standing wave field when single-frequency ultrasound is used in the water tank, the ultrasonic field in the water tank is very uneven. The ultrasonic wave is easily absorbed by the fiber due to its short wavelength, so the ultrasonic attenuation is large, which makes the fiber not clean. However, high-frequency ultrasound has certain advantages in cleaning the surface of fibers due to its high vibration frequency.

specific embodiment

Embodiment 1 Ultrasonic wool washing device

Figure 2 is a schematic diagram of an ultrasonic hair washing device in a typical embodiment. Including multi-frequency ultrasonic vibrating box 4, mesh plate 3, washing tank 2 and a wool guide device in the water tank, multi-frequency ultrasonic vibrating boxes are installed evenly at intervals of 20cm on the mesh plate of the water tank, and multi-frequency ultrasonic vibrating box 4 is pressed They are fixed in the lower part of the water tank in a certain order and at a certain distance, and the upper surface of the vibrating box is flush with the sand leakage screen 3 . The radiating surface of the ultrasonic box is facing the raw wool in the washing tank, and the ultrasonic box radiates a certain power of ultrasonic waves in the water tank, so that an ultrasonic wave with uniform intensity is formed in the water tank. The ultrasonic wave acts on the raw wool, so that the mechanical effect of the ultrasonic wave (such as the particle vibration displacement, velocity, acceleration, sound pressure, etc. It works simultaneously with the cavitation effect. Under the action of these three effects, the liquid gas nucleus in the tank expands and grows up, and is filled with the surrounding liquid vapor or gas. The energy is released in a very short time and in a very small space, making the medium locally form a high temperature of hundreds to thousands of K and a high pressure environment exceeding hundreds of atmospheres, and generate a strong impact force, bringing the wool on the raw wool. Some impurities are separated from the fibers to achieve the purpose of cleaning, and then the cleaned raw wool is transported to the next washing tank by the wool guide device 1.
