Square wave driving magnetic lifting device

The invention relates to the technical field of granular material transportation devices applied to an accelerator driven subcritical system (ADS), in particular to a square wave driving magnetic lifting device. The square wave driving magnetic lifting device is characterized by comprising a supporting mechanism, wherein a fixing support is arranged on the supporting mechanism, a solenoid array is mounted in the fixing support, a plurality of solenoids are arranged in a lifting direction to form the solenoid array, each solenoid comprises a bus bar wire for winding a solenoid, an iron yoke is arranged on the periphery of the bus bar wire, a fixing end plate is arranged on the iron yoke, electrifying terminals and cooling water nozzles are arranged on the fixing end plate, the cooling water nozzles are used for charging water to dissipate heat, fixed threaded holes are formed in the fixing end plate, the solenoid array is connected with the fixing support through the fixing end plate, and a grain injecting mechanism is connected with the lower end of the fixing support and is also connected with a conveyance pipeline. The square wave driving magnetic lifting device has the advantages that a conveyance channel is easy to close, the safety is high, the operation is stable, the fault rate is low, the system structure is simpler, and the operation environment for ADS targets can be met.
