Centrifugal discharging device for grouting equipment

Abstract

The invention relates to a centrifugal discharging device for grouting equipment. The centrifugal discharging device for the grouting equipment comprises a driving shaft, a screw pump rotor and a screw pump stator, the driving shaft is connected with the top end of the screw pump rotor, and the bottom end of the screw pump rotor extends into an inner cavity of a cylindrical groove and is connected with a centrifugal scraper. The bottom end of the screw pump rotor extends into the inner cavity of the cylindrical groove and is connected with the centrifugal scraper, the centrifugal scraper is driven to rotate through rotation of the screw pump rotor, the centrifugal scraper generates tangential thrust in the rotating process, wet mixed slurry deposited in the inner cavity of the cylindrical groove is conveyed to a discharging port, and then the wet mixed slurry is conveyed out through a connecting piece and a quick-connection male head, so that the wet mixed slurry is prevented from remaining at the bottom of the inner cavity of the cylindrical groove to cause blockage of a pipeline. The centrifugal discharging device for the grouting equipment is simple in structure and high in discharging efficiency, materials cannot be left and accumulated in the pipeline, and meanwhile, the pipeline is convenient to clean, so that the centrifugal discharging device has a certain application prospect in the field of centrifugal discharging of the grouting process.

Description

technical field [0001] The invention belongs to the technical field of centrifugal discharging equipment, and in particular relates to a centrifugal discharging device for grouting equipment. Background technique [0002] The solid radioactive waste of nuclear power plants mainly comes from the radioactive solid waste generated during the annual refueling overhaul and operational events of the unit in normal operation, such as spent filter elements and compressed barrel cakes, etc. All these radioactive wastes are collected by the solid waste treatment system (TES system) and its ancillary facilities. Through the operation steps of collecting, classifying, temporarily storing, compressing and barreling, barreling and solidifying solid radioactive waste, and barreling and fixing solid radioactive waste, the purpose of effectively containing solid radioactive waste is achieved, and a standard solid waste package is formed to meet the requirements of the state. Requirements fo...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a centrifugal discharge device for grouting equipment, and solve the problem of easy accumulation of wet mixed grout around the positioning shaft of the screw pump installed inside the discharge terminal due to the small internal space of the discharge terminal On the one hand, it is inconvenient to clean the pipeline, on the other hand, the internal blockage of the discharge terminal pipeline may occur after long-term use, reducing the grouting flow rate and reducing work efficiency; further, it also solves the problems of gas, liquid and solid in the mixing container The mixture of multiphase flow is easy to form small powder agglomerates during the mixing and stirring process, and too many small powder agglomerates will affect the performance of the final fixed body medium and other issues
