Problems solved by technology

During the maintenance of nuclear power plants, it was found that the main bolt holes of the reactor pressure vessel were cleaned with artificial wire brushes, which took a long time to clean, and the labor intensity was high. The close-range operation had a greater impact on the radiation dose of the workers, and at the same time caused a certain degree of damage to the surface of the workpiece. damage

Abstract

The invention discloses a main-screw-hole ultrasonic cleaner for reactor pressure vessel. The main-screw-hole ultrasonic cleaner comprises a bearing rotation tool platform, ultrasonic vibrating boxes, a first cleanout liquid storage tank, a first waste liquid storage tank, a second cleanout liquid storage tank, a second waste liquid storage tank, lifting devices and an air blower. A first gear and a servo motor are mounted on the bearing rotation tool platform, a speed reducer is mounted at the front end of the servo motor, a second gear is mounted below the speed reducer, and the first gear and the second gear are meshed. The main-screw-hole ultrasonic cleaner for a reactor pressure vessel is capable of ultrasonically cleaning, automatically feeding and discharging water and automatically shearing by wind, so that the entire cleaning process is fully automatic, more convenient and safer to operate.

Description

【Technical field】 [0001] The invention relates to the technical field of ultrasonic cleaning machines, in particular to the technical field of an ultrasonic cleaning machine for main screw holes of reactor pressure vessels. 【Background technique】 [0002] The reactor pressure vessel is a closed container that houses the nuclear reactor and withstands its huge operating pressure, also known as the reactor pressure vessel. Reactors used in nuclear power plants mainly include light water reactors (pressurized water reactors and boiling water reactors), heavy water reactors, gas-cooled reactors, and fast reactors. Since the pressure vessel contains the active area of ​​the reactor and other necessary equipment, its structural form varies with different reactor types. During the maintenance of nuclear power plants, it was found that the main bolt holes of the reactor pressure vessel were cleaned with artificial wire brushes, which took a long time to clean, and the labor intensi...
