A continuous filtration and reuse system for cutting fluid

Abstract

The invention discloses a cutting fluid continuous filtering and recycling system, belongs to the field of machining devices, and aims to solve the problems that a cutting fluid filtering system needsto frequently replace / clean a filtering screen, and filtration purification efficiency is low in the prior art. The technical scheme includes that grading filtration is implemented by the aid of a primary filtering unit and a secondary filtering unit, thoroughly filtering is ensured, the secondary filtering unit comprises a filtering film, a supporting component and a driving mechanism, the supporting component drives the filtering film to move under driving of the driving mechanism, parts of filtering films adhered with cutting scraps are led out from a first clamping groove, clean parts ofthe filtering films are moved to the communication position of the primary filtering unit and the secondary filtering unit, cutting fluid is continuously filtered, manual frequent replacing and replacing of the filtering film is omitted, and the system is simple in structure, low in machining cost and simple and convenient to use as compared with an existing cutting fluid filtering system.

Description

technical field [0001] The invention relates to the field of machining equipment, more specifically, it relates to a cutting fluid continuous filtration recycling system. Background technique [0002] In the field of machining, cutting fluid is often reused in order to reduce production costs. However, due to the different materials and processing methods of various manufacturers, the size of the processing debris is also different. In the process of cutting fluid circulation, there will inevitably be Part of the fine iron filings are mixed into the cutting fluid, and at the same time, the oil stains generated during machining will be mixed into the cutting fluid, so that the oil stains and powdery debris are mixed together. As the circulating cutting fluid is mixed into the oil cooling system, it will cause system failure. Even damage, thus affecting the normal operation of the equipment. [0003] The Chinese patent with the existing application notification number CN10835...

AI Technical Summary

Problems solved by technology

[0004] However, the filter boxes of this filter system all use filter screens to filter, and when filtering cutting fluids with a large amount of impurities, there will be the following problems: 1. The utilization efficiency of the filter boxes at each level is different, and often the previous level The filter in the filter box is blocked by cutting chips, and the filtration is slowed down, and the filter box of the next stage has not fully exerted its filtering effect, which seriously affects the filtration and recycling efficiency of cutting fluid; If the screen is clogged, the filter box needs to be cleaned frequently or the filter screen needs to be replaced
