Tertiary filtration-circulation system for cutting fluid of machine tool during machining

Abstract

The invention discloses a tertiary filtration-circulation system for a cutting fluid of a machine tool during machining. The tertiary filtration-circulation system comprises an engine body, wherein adirty fluid bath is arranged on the front side of the machine body; a scraper chip-removal device is arranged in the dirty fluid bath; a backflush drum filter is arranged on the rear side of the dirtyfluid bath; a buffer box is arranged on the side of the filtration water outlet of the backflush drum filter; a backflush pump is arranged on the side, close to the backflush drum filter, of the buffer box; the water outlet of the backflush pump is arranged on the side of the drum of the backflush drum filter; a lift pump is also arranged on the buffer box; a series vortex device is connected with the lift pump through a pipeline I; a dirt collection box is arranged at the bottom of the series vortex device; a fluid purification box is connected with the water outlet of the series vortex device through a pipeline II; an internal cooling pump is arranged on the fluid purification box; and a double-bucket pipeline filter is connected with the water outlet of the internal cooling pump through a pipeline III. Compared with a conventional chip removal machine, a chip removal machine tertiary filtration system, namely the tertiary filtration-circulation system disclosed by the invention, has the advantages that fine particles in the cutting fluid can be further filtered out; furthermore, the continuous filtration can be achieved without halting the machine tool and cleaning the filters,and accordingly, the production efficiency of the machine tool can be improved.

Description

technical field [0001] The invention relates to a cutting fluid filtering system, in particular to a three-stage filtering circulation system for cutting fluid of a processing machine tool. Background technique [0002] During the machining process, the machine tool needs to use cutting fluid to lubricate and cool the cutting tool and workpiece. Since a large amount of cutting chips will be mixed into the cutting fluid during the machining process of the machine tool, the cutting fluid must be filtered before it can be recycled. In the past, the chip removal and filtration cycle of the machine tool can only achieve two-level filtration, and usually the first-level filtration can only reach a filtration accuracy of 1000μ, and the second-level filter is forced to achieve a filtration accuracy of 40-50μ through a single-barrel pipeline filter, which leads to The result is that the pipeline filter of a single barrel is cleaned frequently, and the operation of the entire system ...
