Abstract
The utility model relates to the technical field of sludge drying devices, in particular to a sludge drying device for sewage treatment. According to the technical scheme, the cutting device comprises a machine body and further comprises two sets of sliding blocks installed in the machine body in a sliding mode, a first reset spring is fixedly installed between the two sets of sliding blocks, two sets of supporting plates are fixedly installed on the two sets of sliding blocks of the machine body, second reset springs are fixedly installed between the sliding blocks and the supporting plates, and cutting rollers are rotationally installed on the sliding blocks. A driving mechanism is installed on the machine body and drives the two cutting rollers to synchronously and reversely rotate. When broken stones appear between the two cutting rollers, the two cutting rollers are driven to be far away from each other by the counter-acting force of extruding the broken stones generated by the two cutting rollers, at the moment, a gap is formed between the two cutting rollers, and the broken stones fall below the two cutting rollers through the gap. Therefore, the cutting roller is prevented from being stuck, and the service life of the cutting roller can be effectively prolonged.
