Embodiment Construction

[0081] figure 1 It is a schematic diagram of the slurry regeneration apparatus of this invention.

[0082] As shown in the figure, the slurry regeneration device 1 of the present invention is equipped with: a centrifugal separator 2, a first recovery tank 3 for recovering abrasive grains (primary separation), and a second recovery tank 3 for recovering cutting chips (secondary separation). Recovery tank 4, third recovery tank 5 for recovering dispersion medium, fourth recovery tank 6 for recovery of mixed liquid, blending tank 7 for blending regenerated slurry, branch tank 8, switching device 9. Each of the centrifugal separators 2 includes two motors (first motor 10 and second motor 11 ) capable of generating a centrifugal force different from low-G or high-G.

[0083] The waste slurry to be separated consists of abrasive grains, cutting chips (sludge), and dispersion medium (oil). Cutting chips are generated when a not-shown brittle material is cut and processed by a wire ...

Abstract

A slurry regenerating device provided with a centrifugal separator (2) for allowing waste slurry to be inserted therein, a discharge opening (12) for discharging a primarily separated substance and a secondarily separated substance from the centrifugal separator (2), a first collecting vessel (3) communicating with the discharge opening (12) through a route (8a) for the primarily separated substance, a second collecting vessel (4) communicating with the discharge opening (12) through a route (8b) for the secondarily separated substance, a liquid discharge opening (13) for discharging dispersed soot or a mixed liquid of the dispersed soot and the secondarily separated substance, a third collecting vessel (5) and a fourth collecting vessel (6) which communicate with the liquid discharge opening (13), a blending vessel (7) for generating regenerated slurry, and a switching means (9) for connecting either the route (8a) for the primarily separated substance or the route (8b) for the secondarily separated substance to the discharge opening (12).

Description

technical field [0001] The present invention relates to a regeneration device and method of slurry, in particular to a regeneration device and method of waste slurry after cutting of a wire saw device. Background technique [0002] Currently, in order to reduce costs, waste slurry discharged from processing equipment (for example, wire saw equipment, etc.) using slurry is recycled. The waste slurry of such a wire saw device consists of a dispersion medium, abrasive grains and cutting chips mixed therein. Such separation uses two centrifugal separators to separate abrasive grains and cutting chips from the dispersion medium. Specifically, the waste slurry is put into the first centrifugal separator, and abrasive grains having a specific gravity larger than cutting chips are first separated by a low centrifugal force of less than 1500G. Afterwards, the mixed liquid composed of dispersion medium and cutting chips is poured into the second centrifugal separator, and the cuttin...
