Problems solved by technology

Before the zirconium alloy pipe is polished, the inner surface is washed first, the two ends are plugged and sealed after air blowing, and then the abrasive belt polishing is performed. Since the polishing abrasive belt polishing material is composed of colloid containing sand grains and bonded sand grains, some of them will remain on the surface after polishing. The surface of the pipe, and the original online cleaning equipment cannot effectively remove the residual sticky dirt on the surface of the pipe. The polished pipe needs to be manually wiped the outer surface of the pipe one by one before packaging, and the production efficiency is low.

Embodiment 2

[0042] The invention also provides an ultrasonic cleaning method for the outer surface of the zirconium alloy pipe, such as Figure 2-3 shown, including the following steps:

[0043] In step S101, the zirconium alloy pipe is transported to a first cleaning tank containing a cleaning agent for the first ultrasonic cleaning.

[0044] Specifically, in this solution, the first cleaning tank is provided with a first ultrasonic generator for generating ultrasonic waves. Preferably, the vibration frequency of the first ultrasonic generator is set to 28KHz˜40KHz. The first cleaning tank is filled with a cleaning agent with a concentration of 1% to 5%. The cleaning agent is preferably Alconox powdered precision cleaning agent, which is used to clean the outer surface of the zirconium alloy pipe to be cleaned, and is mainly used to clean the residual adhesion dirt on the surface of the pipe. . In a specific embodiment, the zirconium alloy pipe can be controlled by the conveying system...

Abstract

The invention relates to an ultrasonic cleaning device and method for the outer surface of a zirconium alloy pipe, and the device comprises a first cleaning tank which is internally provided with a cleaning agent, and the bottom of the first cleaning tank is provided with a first ultrasonic generator; deionized water is contained in the second cleaning tank, and a second ultrasonic generator is arranged at the bottom of the second cleaning tank; the cleaning agent recycling tank is arranged between the first cleaning tank and the second cleaning tank and is used for recycling a cleaning agent; the first water return system is arranged on the cleaning agent recovery tank, and when the cleaning agent in the cleaning agent recovery tank reaches a preset water level, the first water return system conveys the cleaning agent in the cleaning agent recovery tank back into the first cleaning tank; after the zirconium alloy pipe enters the first cleaning tank to be subjected to ultrasonic cleaning, dropped cleaning agents are recycled through the cleaning agent recycling tank, and then the zirconium alloy pipe enters the second cleaning tank to be subjected to ultrasonic cleaning. The technical problems that in the prior art, residual adhering dirt on the surface of the zirconium alloy pipe cannot be effectively removed, and the production efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of cleaning the outer surface of a zirconium alloy pipe, in particular to an ultrasonic cleaning device and method for the outer surface of a zirconium alloy pipe. Background technique [0002] Nuclear grade zirconium alloy pipes are generally used as structural components of fuel assemblies, and are required to have good corrosion resistance in nuclear reactors, and their corrosion resistance is related to the safety performance of fuel assemblies in nuclear reactors. The corrosion resistance of zirconium alloy pipes has a great relationship with the surface condition. The finished zirconium alloy pipes need to be polished with abrasive belt to remove the pollution layer on the outer surface. Before polishing the zirconium alloy pipe, the inner surface is rinsed, the two ends are plugged and sealed after air blowing, and then the abrasive belt is polished. Since the polishing material of the polishing abras...
