Example Embodiment

[0023] In order to make the content of the present invention more easily and clearly understood, the following further describes the present invention in detail based on specific embodiments in conjunction with the accompanying drawings.

[0024] The embodiment of the present invention provides an ultrasonic cleaning process for a waste engine, which includes the following steps:

[0025] Initially clean the engine with water and dry it on a dryer to ensure the surface and interior of the engine are dry;

[0026] The dried engine is immersed in the peeling paint. The temperature of the peeling paint is 55 degrees Celsius, so that the surface and the inside of the engine are covered with a film formed by the paint. The peeling paint uses metallocene catalyzed polyethylene and styrene-butadiene The block copolymer is mixed according to the weight ratio of 1:1.

[0027] Place the engine coated with peeling paint in a cold storage, and lower the temperature to -15 degrees Celsius, so that...

Abstract

The invention provides an ultrasonic cleaning technology for a waste engine. The ultrasonic cleaning technology comprises the following steps that the engine is primarily cleaned with water and then dried; the dried engine is immersed into a stripping coating, and the engine coated with the stripping coating is put into a refrigeration house; the refrigerated engine is put into a water tank of anultrasonic cleaning machine to be cleaned; rust removing operation and passivating operation are conducted on the cleaned engine, the engine is put into passivating liquid with the concentration of 15%-18% and then cleaned with passivating liquid diluted to 3%-5% after being passivated; and air drying and surface oil applying are conducted. According to the technology, the waste engine with the complex structure can be internally and externally cleaned, the perfect effects of oil removing, rust removing and dirt removing are achieved, the quality of an ultrasonically-cleaned product is improved, and subsequent manual labor operation is reduced.

Description

technical field [0001] The invention relates to the technical field of ultrasonic cleaning, in particular to an ultrasonic cleaning process for waste engines used in the engine recycling industry. Background technique [0002] Ultrasonic cleaning (ultrasonic cleaning) is to use the cavitation effect, acceleration effect and direct flow effect of ultrasonic waves in the liquid to directly and indirectly affect the liquid and dirt, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning. In the currently used ultrasonic cleaners, cavitation and direct flow are more widely used. [0003] Generally speaking, the cleaning process depends on the difficulty of cleaning the object to be cleaned and the cleaning quantity. The main cleaning process is as follows: hot dipping or spray washing: the purpose is to soften, separate and dissolve the pollutants on the workpiece, and reduce the load of the next cleaning process; ultrasonic cleaning: ...
