Nuclear power plant blender cleaning decontamination device

Abstract

The invention provides a nuclear power plant blender cleaning decontamination device which comprises a gantry support. A lifting system and a flushing system are arranged on the gantry support. The lifting system comprises two lead screws which are vertically arranged on the gantry support. Each lead screw is provided with a nut used in cooperation with the lead screw. The lifting system further comprises a supporting plate. The supporting plate penetrates through the two lead screws and is connected with the lower surfaces of the two nuts. The supporting plate can be driven by the nuts to move up and down along the two lead screws. The flushing system comprises a flushing pipe assembly. The flushing pipe assembly comprises a flushing pipe, wherein the upper end of the flushing pipe is connected with the supporting plate through a flange, the lower end of the flushing pipe is provided with a sprayer assembly capable of rotating, and the flushing pipe can move up and down along with the supporting plate. According to the decontamination device, a blender barrel and a stirring paddle can be cleaned in real time by means of remote control, and materials remaining on the blender barrel and the stirring paddle can be removed quickly and effectively; consumed time is short, and the effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of cleaning, and in particular relates to a cleaning and decontamination device for a nuclear power plant. The decontamination device realizes real-time cleaning of a mixer barrel and stirring paddles in the barrel through remote control. Background technique [0002] At present, most of the radioactive concentrates and waste resins produced in domestic nuclear power plants and nuclear fields are solidified with cement. In the mixer, the stirring paddle installed at the bottom of the bucket is used to rotate the materials quickly and evenly to form cement solidification for permanent treatment. disposal. After the mixing and feeding are completed, a large amount of material will adhere to the mixer barrel and the stirring paddle, which will affect the next stirring. It is necessary to clean the materials remaining on the barrel and the stirring paddle. Because the stirred material is radioactive, it cannot ...
