2 Solid-liquid separation of the two-stage dewatering system with an inclined drum screen and a double taper Screen

摘要

The present invention relates to a solid-liquid separator, and more particularly, to a slurry drum screen capable of improving the productivity as well as alleviating burden of livestock manure processing and subsequent processing by incorporating an inclined drum screen and an inclined drum screen, Stage dewatering type solid-liquid separator having a double-tapered screen.The present invention relates to an inclined drum screen, which is installed upward from one side to the other side, and which performs a primary dewatering while transferring the waste introduced into one side to the other side through a first conveying screw rotationally driven by a first motor; The first dehydrated waste falling from the inclined drum screen is installed at a lower portion of the other side of the inclined drum screen so as to be secondly dehydrated while being transferred from one side to the other side through a second conveying screw rotationally driven by the second motor, A double tapered screen comprising an inner screen having holes formed therein and an outer screen having a plurality of second holes each having a diameter larger tthat of the first hole and passing through the outer surface of the inner screen; A plurality of wire members provided in communication with the other end of the double tapered screen and provided adjacent to each other at a predetermined interval so as to form a cylindrical shape and a coupling member into which a wire member is inserted and fitted into the groove of the unevenness formed on one side, A wedge wire screen for transferring the remaining treatment water from one side to the other side; And a discharge port installed at the other end of the wedge wire screen for discharging waste that has been dewatered by the remaining treatment water,The elastic plate is provided with a hole through which the second conveying screw penetrates at the center, and a hole formed radially outward of the hole, so that the elastic plate is flexibly moved by self-elasticity. A plurality of blades are included,A pressure blocking plate for pressing the elastic plate by the elastic restoring force of the elastic member and a screw for controlling the pressing force of the pressure blocking plate by regulating the compression amount of the elastic member are provided at the end of the second conveying screw penetrating the elastic plate The present invention relates to a two-stage dewatering type solid-liquid separator having an inclined drum screen and a double tapered screen.;
