Mobile grouting device for fixing radioactive waste

Abstract

The invention relates to the technical field of treatment of medium-and-low-level radioactive waste in the nuclear industry, in particular to a mobile grouting device for fixing radioactive waste. Themobile grouting device comprises a control unit, a metering device and a stirring grouting device, the stirring grouting device comprises a stirrer, a screw pump and a post-mixer, the stirrer comprises a stirring rod and a stirring motor, and the stirring motor simultaneously drives the stirring rod, the screw pump and the post-mixer to operate. According to the mobile grouting device for fixingthe radioactive waste, mixing, outputting and grinding are achieved at the same time through the stirring motor, the size is small, movement is achieved, continuous feeding and continuous stirring ofwater, additives and cement and continuous discharging of cement paste can be achieved, and the grouting efficiency is greatly improved; dry powder agglomerates are secondarily crushed by using the post-mixer, so that the uniformity and performance of wet mixed materials are improved; and the equipment is not provided with an independent cleaning pipeline any more, and the mixer can be thoroughlycleaned by replacing the stirring rod with a cleaning rod.

Description

technical field [0001] The invention relates to the technical field of processing low and medium radioactive waste in the nuclear industry, in particular to a mobile grouting device for fixing radioactive waste. Background technique [0002] Nuclear power plants, nuclear technology applications or military industries will produce a certain amount of radioactive solid waste. Reflective waste is divided into different types according to different standards. and high-level radioactive waste. With the rapid development of nuclear energy, the production and accumulation of radioactive waste have also increased. At this time, the disposal of radioactive waste has become an important issue facing the development of nuclear energy. If effective measures cannot be taken to dispose of these wastes, the radioactive waste caused Environmental and personal safety issues will become more and more prominent, and will also hinder the healthy development of the nuclear power industry.
