Abstract
In the process of in-situ uranium leaching from sandstone uranium mines,physical and chemical blockage of the extraction hole filter and surrounding strata can be caused,reducing the extraction amount and affecting normal production.This article introduces several common well washing methods in in-situ leaching uranium mines,with a focus on the structure,principle,and related parameter calculation of a hydraulic pulse self rotating well washing device used for high-pressure jet jet washing.This device utilizes the nonlinear working characteristics of the motor and mud pump,as well as the interaction between the disc spring reaction force,to periodically change the flow area and achieve instantaneous fluctuations in water pressure and flow rate.The water flow acts on the rotor to drive the nozzle to rotate.After multiple experiments and improve-ment,the device has pulse and self rotation functions,and has been applied in Xinjiang Ili Xinjiang CNNC Tianshan Uranium Industry Co.,Ltd.This device is used in combination with high-pressure jet washing and piston washing methods with better results,can increase the injection water pressure and pumping volume,and improve the cleaning efficiency.关键词
