Abstract

The invention discloses a screw-rod-driven and piston-pressurized sludge pelletizer, and belongs to mechanical equipment. The pelletizer consists of a bracket, a main working cylinder, a screw rod, a gear, a column sleeve piston, a motor and a cutter. The pelletizer adopts the mechanical transmission manner of gear transmission and screw rod pressurization, has the advantages of simple structure,low construction cost, high continuous operation efficiency, large extrusion force, high pellet molding stability, pelletizing strength and yield, and the like, and is suitable for the pelletizing treatment of any kind of sludge so as to improve the working efficiency and solve the problems of high cost and working efficiency of special sludge pelletizing equipment.

Description

technical field [0001] The invention discloses a lead screw driven piston pressurized sludge granulator, which belongs to the category of mechanical equipment. Background technique [0002] With the gradual acceleration of the construction of urban sewage treatment facilities and the increasing rate of centralized sewage treatment, the amount of sludge produced by sewage treatment plants has increased dramatically. According to relevant predictions, the amount of urban sewage in my country will increase substantially in the next two decades, and the amount of sewage discharged in 2010 will reach 440×10 8 m 3 / d; In 2020, the sewage discharge will reach 536×10 8 m 3 / d; The amount of sludge usually accounts for 0.3% to 0.5% (volume) of the sewage volume or about 1% to 2% (mass) of the sewage treatment volume. Moreover, if the sewage is further treated, the amount of sludge will increase by 0.5 to 1 times. At present, my country's sewage treatment capacity and treatment r...
