SCREW PRESS EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide screw press equipment which contrives improvement of treating ability without causing a huge size and prevents the clogging accompanying an increase in the treating ability. SOLUTION: This screw press equipment 20 is constituted in such a manner that a filtration cylinder 21 of which the side edge plate 21c on a feeding port 21a and the peripheral side surface 21d are formed by a filtration member having a large number of pores such as punching metal and a screw shaft 22 having screw vanes 22b on the central shaft is freely rotatably arranged on the central shaft. As a result, filtration can be performed even in the part of side edge plate which is closed in the conventional technique and the treating ability is increased without causing a huge size of apparatus.
