Description

Rotary ultrasonic cleaner

Technical Field

The utility model relates to a rotary ultrasonic cleaner.

Background

The ultrasonic cleaner utilizes cavitation of ultrasonic wave in liquid to accelerate and directly flow in to disperse dirt layer directly or indirectly, and to emulsify and strip to clean. The ultrasonic cleaner has the following advantages: (1) No matter how complex the shape of the workpiece is, the ultrasonic cleaning effect can be achieved as long as the workpiece can be contacted with liquid; (2) The bubbles generated by the liquid during cleaning are very uniform, and the cleaning effect is very uniform;

(3) The cleaning effect is good. The cleaning methods of industrial cleaning are generally manual cleaning, organic solvent cleaning, vapor phase cleaning, high-pressure water jet cleaning and ultrasonic cleaning. Ultrasonic cleaning is internationally recognized as the most efficient and effective cleaning method at present. The cleaning efficiency reaches more than 98%, and the cleaning cleanliness reaches the highest level. The cleaning efficiency of the traditional manual cleaning and organic solvent cleaning is only 60% -70%, and even the gas phase cleaning and high-pressure water jet cleaning are also lower than 90%. No matter how complex the shape of the workpiece is, the ultrasonic cleaning effect can be achieved as long as the workpiece can be contacted with liquid. Particularly, the cleaning agent has remarkable cleaning effect on workpieces which cannot be cleaned completely and effectively by cleaning methods such as complicated shapes and structures, manual work and the like. The bubbles generated by the liquid in the cleaning process are very uniform, and the cleaning effect of the workpiece is very ideal. The ultrasonic cleaning can achieve different effects according to different solvents. Ultrasonic cleaning effects such as rust removal effects. The cleaning agent is used for accelerating the separation and dissolution of pollutants, so that the cleaning agent can be effectively prevented from corroding a workpiece;

(4) And (5) cleaning without damage. Ultrasonic cleaning belongs to non-contact cleaning, and secondary treatment is not needed to be carried out on a workpiece after cleaning, so that the surface of the workpiece is not damaged. Ultrasonic cleaning is particularly suitable for objects with complex, high-precision and high-surface-quality requirements.

When the ultrasonic cleaner in the existing market is used for cleaning, a workpiece (such as a cylinder body or a box body and the like) is placed into a cleaning tank filled with cleaning liquid, and an ultrasonic transducer in the cleaning tank is started to work so as to clean the workpiece; and fishing out the workpiece cleaning tank after the cleaning is completed. For example: the prior art discloses a novel ultrasonic cleaner (CN 112605053A), which comprises an acoustic cleaner body, a cleaning tank, a part placing basket for placing the part to be cleaned in, and a height adjusting mechanism for lifting or dropping the part placing basket. When the ultrasonic cleaning device is used, a workpiece is placed in the part placing basket, descends through the height adjusting mechanism and falls into the cleaning tank, then is cleaned by ultrasonic waves, and after cleaning, the part placing basket is lifted through the height adjusting mechanism, so that the workpiece is fished out of the cleaning tank. The above prior art also suffers from the following deficiencies and is analyzed as follows:

(1) Because all workpieces in the same batch in the part placement basket (cleaning tank) need to be put in and taken out simultaneously, the put-in and take-out operations occupy a lot of time, and during the operation, the cleaning discontinuity exists in the cleaning tank due to the absence of the workpieces, so that the problems of energy consumption waste and low working efficiency exist;

(2) Because the workpiece is put in and taken out of the cleaning tank and is operated near the cleaning tank, no protective measures exist, and the problems of unsafe conditions such as skin redness, eye penetration, high-temperature scalding and the like caused by the contact of the cleaning liquid with human bodies due to splashing (during putting the workpiece) and dripping and flying (during taking the workpiece) of the high-temperature cleaning liquid exist during ultrasonic cleaning under the heating state of the cleaning liquid;

(3) Because the workpiece is in a horizontal state in the part placing basket (cleaning tank), the problem that the workpiece (particularly similar to a cylinder body or a box body type hole is a plurality of parts) is unfavorable for cleaning and discharging impurities in the hole in the horizontal direction when the workpiece is stably placed;

(4) Because the existing plurality of workpieces are in the part placement basket, the hardness of the part placement basket (such as plastic material) is lower than that of the workpieces, and the workpieces cannot be damaged, but the part placement basket shakes, so that the workpieces are contacted or collided after mutually moving, and the precision surfaces and the precision parts of the workpieces are damaged.
