The invention discloses an efficient press block pulverizing device for sludge treatment, and belongs to the field of environment protection equipment. The efficient press block pulverizing device comprises a shell. A pulverizing cavity and a discharging cavity are formed in the shell. The feeding port is formed in the bottom of the shell, and the feeding port communicates with the pulverizing cavity. A pulverizing device, a protruding block, an arc filter net, pulverizing blocks, a second connecting rod, a filter net plate, pulverizing teeth and fixing blocks are arranged in the pulverizing cavity. The two fixing blocks are arranged and symmetrically arranged on the left inner wall and the right inner wall of the bottom of the pulverizing cavity and correspond to the pulverizing blocks. The efficient press block pulverizing device is reasonable in structural design, solid garbage in sludge can be pulverized through a driven pulverizing wheel and a drive pulverizing wheel, the pulverizing blocks can be made to pulverize and grind the sludge through the pulverizing teeth via a circular reciprocating device, and the sludge pulverizing quality is improved. A spiral blade arranged in the discharging cavity can convey pulverized sludge to a discharging port to be discharged, sludge accumulation in the discharging cavity is avoided, and time and labor are saved.
