Several Common Sludge Dewatering Equipment

There are three main types of sewage desliming equipment: first, spiral sewage desliming equipment compresses sludge through spiral extrusion; Secondly, the sludge dewatering equipment of dewatering centrifuge uses centrifugal force to dewater sludge; Thirdly, vacuum filtration sludge dewatering equipment continuously operates to dewater sludge through automatic control. First of all, the cascade spiral equipment can well separate the solid phase from the liquid phase in the sludge, and unclean water will flow out through the filter screen and the sludge will be squeezed by the spiral. Secondly, in the dewatering centrifuge equipment, the sludge enters the rotating drum with rotating shaft, and keeps half rotation, and the speed increases. Under the action of centrifugal force, sludge and water are polarized due to different specific gravity, and finally sludge is left and water is discharged from the equipment. Thirdly, vacuum filtration equipment can be automatically controlled and run continuously, with high efficiency, but it also has the disadvantage of frequent cleaning. This machine is bulky, troublesome to clean and complicated to operate.
