ス型脱水機の改良に関するものである。[Detailed description of the invention] The present invention uses sludge generated during the clarification of water, wastewater, and other liquids, or flocculated sludge obtained by adding an organic polymer flocculant or other flocculant to this sludge and flocculating it. Regarding improvements to a screw press type dehydrator consisting of an outer cylinder of cylindrical furnace material, which is capable of continuously compressing and dehydrating the furnace liquid using a screw shaft with screw blades, and converting the dehydrated cake into raw skin with extremely low moisture content. It is something.

出し順次圧搾し、汚泥より絞り出された炉液を外筒２３
より排出させ脱水ケーキを脱水ケーキ排出口２６より取
り出すようにした構造、機能を有している。For example, as shown in FIG. 1, a conventional screw press has an outer cylinder 23 of a cylindrical furnace material provided between a sludge supply port 21 and a dewatered cake discharge port 26 of a sludge hopper 22, and screw blades 24 on the outer periphery. Furthermore, the annular gap volume between the outer cylinder 23, the screw shaft 25, and the screw blades 24 is appropriately reduced, and the sludge introduced into the sludge supply port 21 is transferred to the shaft by the rotation of the screw shaft 25. The sludge is extruded and squeezed sequentially in the direction of the dewatered cake discharge port 26, and the furnace liquid squeezed out from the sludge is transferred to the outer cylinder 23.
It has a structure and function that allows the dehydrated cake to be discharged further and taken out from the dehydrated cake discharge port 26.
