Recycling method for machining cutting fluid

Abstract

The invention relates to a recycling method for machining cutting fluid. The recycling method for the machining cutting fluid adopts the following cutting fluid recycling device; the cutting fluid recycling device comprises a box body and supporting legs; the supporting legs are fixedly installed at the lower surface of the box body; a bottom liquid outlet is fixedly installed at the bottom end ofthe left side of the box body; a U-shaped communicating vessel structure is arranged at one end of the left side of the device, so that large-particle impurities in the device are filtered out through a first filter plate and a second filter plate which are arranged in the device; afterwards, through a first turbulent flow plate and a second turbulent flow plate, the preliminarily filtered liquidreaches a laminar-flow-like state, and the flow resistance of the cutting fluid in the liquid is increased, so that the flow speed of the cutting fluid at the bottom of the U-shaped communicating vessel structure is reduced, and then impurities can be settled again in a slow flowing process of the waste cutting fluid; and thus, relatively large impurities in the cutting fluid are removed to guarantee the subsequent filtration quality of the cutting fluid.

Description

technical field [0001] The invention relates to the technical field of recycling cutting fluid, in particular to a method for recycling cutting fluid in machining. Background technique [0002] Cutting fluid is an industrial liquid used for cooling and lubricating cutting tools and workpieces during the grinding process of metal chips. down, to prevent contamination of the machine tool, workpiece, and cutting tool, to ensure that the cutting edge of the cutting tool or grinding wheel remains sharp without affecting the cutting effect, and the used cutting fluid will be recycled and reused through the recycling device, but the existing recycling device There are some problems: [0003] The existing recovery device needs to filter the chips, small iron pieces and sand particles in the cutting fluid before they can be reused. However, when the existing recovery device is used, the used cutting fluid is generally poured into the device. In the recovery device, iron filings, sm...

Problems solved by technology

[0003] The existing recovery device needs to filter the chips, small iron pieces and sand particles in the cutting fluid before they can be reused. However, when the existing recovery device is used, the used cutting fluid is generally poured into the device. In the recovery device, iron filings, small iron nuggets and other impurities in the cutting fluid are removed by sedimentation and insertion of electromagnetic rods. However, large particles of impurities must be removed by sedimentation. This method of removing impurities is not only inefficient, but also For the method of inserting electromagnetic rods into it to absorb small iron filings and other impurities, due to the size limitation of the electromagnetic rods, for a recovery device with a large amount of used cutting fluid, the amount of impurities that can be adsorbed on each electromagnetic rod If the mass is too small and the adsorption range is very limited, if the internal liquid flow is not increased by agitation, the internal impurities cannot be removed more completely, but if agitation will affect the large particles of impurities precipitated at the bottom, It is remixed in the cutting fluid, so multiple equipment processes are needed to complete the recovery effect of the cutting fluid, so the existing recovery devices are not very ideal in terms of recovery efficiency and effect
