Sludge drying equipment and method

The invention relates to sludge drying equipment and method.The sludge drying equipment comprises a drying box, a crushing and feeding device, an upper belt conveyor, a lower belt conveyor and a discharging part, agglomerated sludge is crushed through the crushing and feeding device and then falls into a storage port, and a rotating shaft drives the sludge in the storage port through a rotating disc to rotate to be aligned with a discharging port; after sludge is discharged to the upper belt conveyor, the sludge is conveyed to the lower belt conveyor through the upper belt conveyor and then conveyed into the discharge hopper through the lower belt conveyor, the rotating ball is driven by the electric shaft to rotate in the discharge pipe, the storage tank is made to alternately turn to the upper side and the lower side of the discharge pipe, and the sludge on the upper side of the discharge pipe is transferred to the lower side of the discharge pipe. According to the sludge drying device, the sludge can be co
