According to the present invention, the case having an internal space; A cylindrical case which is installed in the interior of the bowl; Rotatably installed in the interior of the bowl, the screw conveyor is provided in the hollow interior such that the sludge is supplied from the outside; Installed respectively coupled to said ball-and screw conveyors, the power supply unit for generating a driving force to rotate the bowl and the screw conveyor; Air supply section which causes the first power upon which the ball-and screw conveyors rotate by the study, while the air jet in the bowl and the lower end of the screw conveyor, the bowl and the screw conveyor is rotated in the state of floating upward; Is installed and connected to the bottom of the case to support the case, a screw-decane ether type centrifuge comprising a support part for holding a vertical or horizontal position is provided for selectively the bottom of the case.
Decanoic ether type screw centrifuge according to the invention, by improving the structure of a horizontal to a vertical structure, it is possible and installation work in a small space. Therefore, it is excellent in space efficiency, when moving it is possible to secure the stability and ease of movement by switching to the horizontal structure. In addition to the release of existing vertical structures rotated by the mechanical mechanism bearing by the drive motor, the air (air) to thereby by rotation and to support the bowl and the screw conveyor, a high speed of more to minimize the rotational load in the direction of gravity the noise and vibration are reduced, not only can be obtained to improve the working efficiency, and reliability.
