Deep dehydration mechanism and belt type dehydrator with same

Abstract

The utility model discloses a deep dehydration mechanism and a belt type dehydrator with the deep dehydration mechanism, and the deep dehydration mechanism comprises a driving dehydration roller which is rotatably arranged on a rack; the plurality of grinding rollers are annularly wound on the outer side of the driving dewatering roller, a squeezing passage is formed by the grinding rollers and the outer surface of the driving dewatering roller, and the upper filter cloth and the lower filter cloth penetrate through the squeezing passage in a transmission manner; the tensioning assembly is connected with the plurality of grinding rollers and applies tensioning force to the plurality of grinding rollers; the high-frequency vibrator is arranged on the tensioning assembly and transmits high-frequency vibration waves to the grinding rollers so that the high-frequency vibration waves can act on the cenobium in the sludge and wall breaking of the cenobium can be achieved. The large-diameter driving dewatering roller is adopted and combined with high-frequency vibration tensioning, the filter cloth has a larger wrap angle and a larger squeezing dewatering area during deep dewatering, cenobium in sludge generates a wall breaking effect under the rolling pressing force of the grinding roller and the high-frequency vibration effect, so that water wrapped in the cenobium is separated out, and the dewatering effect is greatly improved. The dewatering efficiency is high, the structure is simple and the practicability is strong.
