Title:
SLUDGE RECOVERY DEVICE
Document Type and Number:
Japanese Patent JP2015231644
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sludge recovery device capable of efficiently separating-removing sludge, by taking out a mixed fluid recovered in a tank to the outside of the tank from a required position of a bottom wall, by avoiding deposition of the sludge in a bottom part of a mixed fluid recovery tank.SOLUTION: A used working liquid discharged from a machine tool 5 is recovered to a mixed fluid recovery tank 1, but in the mixed fluid recovery tank 1, a recovered mixed fluid F flows by imparting turning directivity in one direction by a discharge flow discharged from a sludge separator 2. Thus, sludge mixedly existing in the mixed fluid is avoided in stagnating and depositing in a corner part of the bottom part periphery by forming a corner part of the bottom wall periphery of the mixed fluid recovery tank 1 as a gently continuing continuous surface, and by a turning flow of the mixed fluid F in this tank. Since a bottom wall surface becomes a downward pitch toward a current collection part from its periphery, the sludge is sucked from a fluid suction port 22 without precipitating-depositing on a tank inner bottom surface, and is filtered by the sludge separator 2, and the sludge mixedly existing in the mixed fluid F is separated-removed.
