Abstract

In a narrow used paper processing space of a used paper recycling apparatus of furniture size, this is a dewatering device for executing smoothly and efficiently a dewatering process as a principal component of a paper making process for manufacturing used paper pulp. Being disposed in a linkage location between a mesh belt and a smooth surface belt, and configured to roll and squeeze the mesh belt and the smooth surface belt from the upper and lower sides in a compressed state, the apparatus includes a preliminary dewatering roll unit for squeezing and dewatering preliminarily the wet paper on the mesh belt, and a final dewatering roll unit for squeezing and dewatering the wet paper on the mesh belt preliminarily dewatered in the preliminary dewatering roll unit to obtain dry paper of specified water content. Therefore, in a very narrow used paper processing space of a used paper recycling apparatus of furniture size, the dewatering process in the paper making process for manufacturing used paper pulp can be executed smoothly and very efficiently.
