Rectifying tower capable of cleaning sieve plate in staggered manner

The invention discloses a rectifying tower capable of cleaning sieve plates in a staggered manner, and relates to the technical field of rectifying towers, the rectifying tower comprises a tower body and a liquid collector, and the top of the tower body is provided with an end socket. According to the rectifying tower capable of cleaning the sieve plate in the staggered mode, a driving motor is matched with an output shaft, a belt wheel and a transmission belt drive a lead screw to rotate, when the lead screw rotates, a thread sleeve on the outer side can be driven to slide, and then the thread sleeve drives a cleaning brush to clean the sieve plate; meanwhile, a thread sleeve pushes an elastic wheel to move through cooperation of a first wedge-shaped block and a second wedge-shaped block, then the elastic wheel enables a transmission belt on the top to be in a loose state, under cooperation of a first connecting rod and a movable block, the elastic wheel at the bottom moves, and at the moment, the transmissi
