Abstract: In-situ leaching uranium is a advanced mining technology, which is widely used by most uranium mining countries.A uranium deposit in ordos basin, uranium ion exchange tower filtration unit operation in the process of filter blockage, breakage, etc., leading to the tower of ion exchange resin and sediment can't effective separation, thus affecting ion exchange column fluid saturation capacity problem of ability and the resin, introduction of self-cleaning filter technology concept and brush cleaning method, tower filters is proposed to improve technical scheme, in 316L outer lining reinforcement skeleton type articles around the coil bracket welded filtering device, based on the research to form the suitable filtering precision, high crushing strength, simple operation, easy to tear open outfit, low input, can be a new type of self-cleaning automatic cleaning tower filter device, the effects of the resin and the sediment separation.And the automatic cleaning of the filter device after plugging, the recoil flow rate after cleaning is restored to more than 96% of the initial flow rate, reaching the continuous filtration and automatic cleaning of the filter device at the top of the ground leaching uranium mining tower, and improving the continuity and stability of the ion exchange process.The application of the device reduces the labor intensity of employees, improves the working environment, and has good economic benefits and safety and environmental protection benefits.
