Continuous dewatering method and continuous dewatering device such as sludge, excess body and their processing residue

摘要

A continuous dewatering apparatus comprises left and right dewatering drum gears meshing with each other and disposed in a frame. Each of the drum gears is formed of a hollow cylindrical drum having many teeth formed on the periphery thereof. Many water passage holes are formed through the tooth crests and bottom lands of the teeth of the hollow drum. Left and right endless filter cloth belts are stretched around the drum gears and left and right roller groups disposed in the vicinity of the drum gears. The filter cloth belts may directly be adhered to the drum gears. The left and right drum gears and cloth belts are rotated together by a driving unit to mesh with each other. Objects such as sludge, fruits and vegetables and wastes of processed fruits and vegetables are continuously charged onto a meshing location of the drum gears and cloth belts to dewater the objects by pressing force of the meshing drum gears. As a result, the objects are continuously dewatered at a high dewatering rate.
