Embodiment Construction

[0036] A fuel rod cladding nozzle automatic spraying device of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] Such as figure 1 As shown, the fuel rod cladding tube nozzle automatic spraying device of the present invention includes: a workbench support 1, an axial conveying device 2, a radial conveying device 3, a material ejecting mechanism 4, a feeding mechanism 5, and a rotating clamping mechanism 6. Wet wiping mechanism 7, dry wiping mechanism 8, loading rack 9, unloading rack 10 and purging device 17.

[0038] The workbench support 1 is used to support and install various components. There are multiple axial conveying devices 2, which are fixed on the upper end surface of the workbench support 1 and arranged in two straight lines on the workbench support 1 to form the axial conveying devices 2 for each straight line. the same amount. There are also multiple radial conveying devices 3, which...

Abstract

The invention belongs to the technical field of fuel assemblies and particularly relates to an automatic spraying and wiping device for a fuel bar cladding pipe opening. The automatic spraying and wiping device for the fuel bar cladding pipe opening comprises a worktable support, an axial conveying device, a radial conveying device, a material jacking mechanism, a feeding mechanism, a rotary clamping mechanism, a wet wiping mechanism, a dry wiping mechanism, a feeding frame, a discharging frame and a purging device. By means of the automatic spraying and wiping device for the fuel bar cladding pipe opening, the technical problems that in the current stage, a pipe opening of a fuel bar cladding pipe is completely operated through manual work, a large amount of labor force is wasted, and the cleaning quality is not stable need to be solved, the automatic spraying and wiping device is used for spraying and wiping the cladding pipe, the cleaning degree of the interior and the exterior of the pipe opening of the cladding pipe is ensured, the spraying and wiping quality is stable, and the welding quality defects generated due to uncleanness of spraying and wiping are reduced; and in addition, by the adoption of the device, automatic spraying and wiping of the cladding pipe is achieved, an original manual spraying and wiping manner is replaced, post persons are reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of fuel assemblies, and in particular relates to an automatic spraying and wiping device for fuel rod cladding pipe nozzles. Background technique [0002] The cladding tube is a protective barrier for the safe operation of nuclear power plants and plays a vital role in the safe operation of the reactor. The cleanliness of the cladding tube orifice directly affects the welding quality. In the production process of nuclear fuel rods, in order to ensure the welding quality, before pressing the upper and lower end plugs, the nozzle of the cladding tube must be sprayed and wiped with silk cloth dipped in acetone, so that the cleanliness of the nozzle of the cladding tube can meet the welding requirements. The wiping work is completely manual. Contents of the invention [0003] The technical problem to be solved by the present invention is: at present, the nozzle cleaning of fuel rod cladding tubes is complete...
