A multi-stage step-by-step renewable resource recycling sorting method

Abstract

The present application relates to solid waste resource processing technology field, especially to a kind of multistage stepwise recycling resource circulation sorting method, the method includes: after being pretreated, uniform feeding of recycling resource raw materials;Central control unit is preset for each step sorting range and step threshold, material is sequentially entered each sorting level, real-time detection of material characteristics by sensor detection unit, and according to the detection result, material is separated to corresponding product branch or imported into circulating return material unit;When instantaneous material thickness is over limit during sorting process, at least one adjusting operation of reducing linear velocity, adjusting range parameter and importing into circulating return material is executed;Circulating material is sent back in proportion after buffering, and material that is still not captured after preset step number or cycle number is discharged as final tailings;The present application realizes multistage stepwise recycling resource circulation sorting, with the advantages of high sorting precision, high resource recovery rate, high equipment utilization, strong adaptability and the like.
