体５から取出し、開口49より排出する。Since the sedimentation tank body 5 has a shape that becomes narrower downward, the sediment concentrates on the take-out screw conveyor 44 and precipitates in the spiral blade 46 at a high concentration.
The precipitate is taken out of the sedimentation tank body 5 by the screw conveyor 44 for taking out, and discharged through the opening 49.

The liquid separated from the bottom by its own weight, and the sediment moves upward as it moves upward.Then, the dried state progresses, and finally, the sufficiently dried sediment precipitates from the opening 57 at the upper end of the screw conveyor 51 for removing the liquid. The sediment is collected in the sediment storage container 60 through the object falling guide cylinder 58. Since this precipitate is a metal powder of a processing material, it is reused.

The invention described in claim 1 does not have the screw conveyor 51 for removing the liquid component, and may directly discharge the precipitate into the container 60 from the tip opening 49 of the screw conveyor 44 for taking out the liquid.

ことができる。 According to the first aspect of the present invention, the used cutting fluid in the machine tool main body is supplied to the sedimentation / separation device through the used liquid extraction pipe, and the sedimentation / separation device removes the surface of the coagulated plate. Impurity fine particles in the liquid are made large by interference coagulation and separated and settled from the cleaning liquid. On the other hand, the cleaning liquid purified by the sedimentation / separation device is taken out from the upper part of the main body container, and the machine tool body is processed by the cleaning liquid return pipe. The sediment deposited in the sedimentation tank at the bottom of the sedimentation separation device is taken out to the outside by a screw conveyor for extraction. Various fine impurity particles to be mixed can be efficiently separated and settled by the sedimentation / separation device, and can be continuously taken out and collected from the sedimentation tank by the takeout screw conveyor. Further, since there is no need to use special components, the apparatus for cleaning a cutting fluid for a machine tool can be provided at low cost. Also,
It is carried out of the sedimentation tank by the take-out screw conveyor.

利点もある。According to the second aspect of the present invention, there is provided a main body container having a special shape formed by the main body upper conical portion, the main body intermediate cylindrical portion, and the main body lower conical portion, and the coagulation plate provided therein. As a result, a conical flow passage whose cross-sectional area gradually expands downward is formed, so that the descent speed of the cutting fluid is remarkably slowed down in this part, and fine particles due to the interference of the surface of the coagulated plate and the inner wall surface of the main body container The mutual agglomeration action is performed effectively, and fine particles such as fine magnetic and non-magnetic metal powders generated during processing such as cutting and polishing can be efficiently aggregated and separated, resulting in excellent processing ability and recovery efficiency. can get. Since the sedimentation / separation device has a high removal rate for removing impurity fine particles from the liquid, there is also an advantage that the machined surface can be finely finished by the cleaning liquid circulated and reused.
