ABSTRACT:
A belt press type dehydration device of improved efficiency includes upper and lower pressing belts of dual layer construction. A first mesh member layer is made of Z-shaped interlocked wire members, and to this is fastened the filter sheet layer. The meshed member layer is designed to provide support for the filter sheet layer and to engage sprocket teeth driven by a motor to advance the belts. Since high tensile strength is no longer required of the filter sheet, it can be thinner and coarser than before, leading to increased dehydration efficiency. Also, the number of pressing drums can be reduced due to the increased efficiency. The upper belt mash layer is made of two separate mesh loops attached to each edge of the filter sheet layer. Sprockets adjacent the pressing drums are spaced near the edges of the belts, to reduce or eliminate leakage over the edges during pressing.
