Description

Metalworking fluid refine device

The present invention relates to a metal processing fluid purification apparatus that enables purification of a processing fluid, cutting oil, cooling water, etc. used in metal processing or non-metal precision grinding processing.

In general, metal processing fluids are used when cutting or grinding metal. Metal processing fluids include processing fluid, cutting oil, and cooling water.

There are machine tools and electric discharge machines as machines that process metal, and any type of machine uses metal processing fluids to protect cutting tools or grinding tools and increase processing efficiency.

The metal processing fluid may include metal fragments, metal powder, and other impurities generated by processing metal.

The used metal processing fluid can be reused through the refining process, and liquid and solid components can be separated during the refining process. The solid content may be metal chips, metal powder, other impurities, and the like described above.

The larger the metal processing scale is, the greater the capacity of the metal processing fluid is, so there is a problem that the size of a purification apparatus for purifying a large amount of metal processing fluid must be increased.

In addition, since the solid content is very heavy, a screw conveyor or the like is used or a magnetic chip conveyor is used to transport the solid content.

However, such a screw conveyor or a magnetic chip conveyor has a problem of occupying an excessive amount of space because the external size is very large.

On the other hand, a drum filter may be used. In general, when the drum filter is filled with solid content, the weight may be 45kg to 50kg or more, which makes handling difficult.

On the other hand, the metalworking fluid used may have a very high temperature, and the metalworking fluid of high temperature may damage the filter, so appropriate measures are required. However, in the related art, the cooling device is provided as a separate device from the purification device, and thus occupies an excessive amount of space in the facility configuration, and management is inconvenient.

In addition, a purification device using a filter or the like can be used when performing non-metal precision grinding. For example, when a product made of ceramic is really grinding, the processing liquid may contain solids, and in order to reuse the processing liquid, the used processing liquid must be refined, and the resulting solid is very heavy.
