DISCLOSURE OF THE INVENTION The present invention relates to a method for suppressing deterioration of water used by mixing or adding additives to a water-soluble cutting oil or a cooling machine. Use a filter to remove antibacterial ceramics (having copper and silver ions) and microorganisms (mucor, altanaria, Escherichia coli, Staphylococcus aureus, green bacterium, Bacillus, lactic acid bacteria, actinomycetes, etc.) General bacteria and fungi such as Legionella spp., Salmonella spp., Black mold, Blue mold, Cladoporium, Fusarium, White habit fungi, Candida, Ecchiara, Saccharomyces, Acanthanem, Nichea, Cladomonas, Hetmacox, Euratria, Folium, Ringbia, Croococcus) Used to control water spoilage.

It is preferable to use an antibacterial ceramic as a filter material capable of coping with the microorganisms described in 0015. In particular, a combination of silver and copper, which are antibacterial metals, as the best essential metals is used. These antibacterial ceramics are those which are improved from those used in Japanese Patent Application No. 8-270406 to improve the antibacterial power, durability and abrasion resistance and further reduce the filling amount. This antibacterial ceramic is disclosed in Japanese Patent Application No. 8-330154 (not disclosed) and in Japanese Patent Application No. 9-2433.
No. 18 (not disclosed) are preferable, and these have a far-infrared emissivity of 95%.
In particular, those having an OH group which generates high electromagnetic waves of 3μ, 6μ and 9μ and has good hydrophilicity are used.

The filter shown in the drawings is preferably a filter obtained by imparting an antibacterial property to an alumina-based or silicon-carbide-based ceramic having a strength for discharging contaminants such as metal pieces and dust. As a method for manufacturing a filter, it is preferable to use a filter that has been commercialized by applying the manufacturing and processing methods described in Japanese Patent Application Nos. 8-33154, 9-310154, and 9-31033 (not disclosed). Particularly preferably, abrasive particles used for the antibacterial whetstone described in Japanese Patent Application No. 9-31033 are carefully selected from # 24 to # 220 and processed into the shape shown in the drawings.

The filters described in FIGS. 2, 3, and 6 to 9 are used as filters other than the above-mentioned 0017. The common feature of the two types is that the metal mesh of # 40 to # 140 covers the antibacterial filter medium and has a filter layer integrated structure. It is possible to filter a small space by increasing the amount of the antibacterial filter material.

The device introduced into the filter layer shown in FIG. 8 is a device for stabilizing the contact surface of the filter medium. By introducing this device, it is possible to efficiently perform the entire surface of the filter medium, which has been unstable until now, with the contact surface of the filter medium.

The filtration contact area and contact time between these antibacterial filtration materials and the diluted aqueous solution to be filtered greatly depend on the circulation amount of the pump. An example is described in Practical Example 0031.

The magnet described in the above 0010 uses a strong magnetic force, and the iron dropped by the cutting or polishing work by this magnetic force takes a small amount of magnetic force and is circulated without being completely discharged, and the iron is again discharged from the instrument nozzle. It is released to the cutting or polishing work site and adheres to the product to cause a scratch. As a solution to the adverse effects of this magnetic force, how to remove dust and metal fragments in the structure of the filter is a method of utilizing a smaller amount of magnetic force.
800 gauss to 1000 gauss are used. In this installation method, the filter is installed on the outer periphery, upper part, and lower part (filter layer) of the filter tank part, and is made to face the same pole to secure a magnetic field region.

By suctioning the filter layer from a pump installed in the filter and rotating the filter in a certain direction, or by dispersing the filter on the upper part (top cover, plate) in the filter and sending a metal having a large specific gravity to the outer peripheral side of the tank. Remove by contact with magnetism.

By attaching iron or the like in the form of fine powder to the surface of the magnet, the iron in the state of the fine powder becomes an adsorption surface for removing iron or the like having a large particle size, and assists the action of sedimentation of the iron. It is effective. This auxiliary effect is achieved by providing a space in the outer tube and the inner tube in the tube structure of the filter and volume in this space.

The filter described in the above-mentioned item 0011 when used alone is the one shown in FIGS. In the factory line, it is possible to control by installing a liquid level gauge on the tank partially diluted aqueous solution of the equipment that is a single unit and adjusting the amount of the solution, making it possible to provide a gradient at the bottom and to remove iron in fine powder state or iron with large particles It serves as a water intake for removal and connects each pipe to supply water to a centralized circulation filter.

Each filter is connected to each other and collected as a centralized circulating filter to remove iron in the form of fine powder or iron having large particles. In addition, other than the filter shown in the drawings, it is preferable to use a rotary filter (for example, Miura Kogyo Z filter series) which has been conventionally used.

This rotary filter has a holding tank below a drum (filter part), and has a feature that this tank part can be filled with an antibacterial filter material and can be used from a small scale. .

In the case of this filter, the filling amount of the antibacterial filter material is large with respect to the amount of the diluted aqueous solution to be treated, and the surface area of the filter is sufficiently secured. It is also possible to add an antibacterial filtration layer to the amount of equipment held.

The antibacterial activity of the exchangeable filter described in Practical Example 0032, a continuous test in which the circulation time was set to 151 per minute and the use time was set to 9 hours a day, and the circulation time described in 0033 and the use time was set to 151 per minute 24 hours a day 2
The type was implemented.

As a result, the maximum circulation amount of filtration that can be performed at 151 per minute and the filling amount of the antibacterial filter material are carefully selected.

Antimicrobial treatment can be performed by increasing the amount of circulation by mixing microorganisms depending on the amount of water-soluble cutting oil released from a nozzle attached to a device such as cutting and polishing.

The three types of filter types (FIGS. 2, 4), filter types (FIGS. 2, 3), and filter types (FIGS. 2, 6, 7, 8, 9) described in the practical examples. Use an exchangeable filter that easily replaces the internal tube, and use it according to the purpose and purpose.

【The invention's effect】

Patent application Hei 8-3301 for antibacterial ceramic
No. 54 (unpublished) By using the product manufactured by the manufacturing method described in Japanese Patent Application No. 9-243318 (unpublished), generation of an unpleasant odor due to propagation of microorganisms was suppressed. This effect is as described in the practical example.

This effect is due to the layered effect by making use of the respective features of far infrared rays and the magnetic and antibacterial metals copper and silver.

Thermal energy is required as a mechanism for generating far-infrared rays, and this energy is considered to receive the thermal energy of a solution using water as a medium and further receive magnetic energy to obtain a layered effect.

The antibacterial metal, copper, has been used for a long time, unlike the rapid decrease in the antibacterial property of the copper ion generator used so far.

Discoloration of water used by mixing or adding additives to a water-soluble cutting oil or a cooler due to binding with other metal substances caused by ion elution by an ion generator or an eluting antibacterial filter material. , Degradation is minimized.

Three types of filter types described in practical examples (types in FIGS. 2 and 4), filter types (types in FIGS. 2 and 3), and filter types (types in FIGS. 2, 6, 7, and 8). The type of the result of the test which uses the exchange type filter which easily exchanges the inner tube of the product according to the purpose and the purpose was carried out, and the result was the viscosity of food oil, sugar liquid, (oil-based, water-soluble) cutting oil, etc. A type suitable for a liquid having a liquid is suitable for a water-soluble and low-viscosity liquid such as a water-soluble cutting oil, water, and a coolant. The type is also suitable for liquids that have viscosity and require antimicrobial activity.

The use of three types of filter types shown in the drawings makes it possible to reduce the installation space required for conventional filter systems.

By using the above three types, it is possible to carefully select the circulation amount, the antibacterial power, and the filtering power according to the processing application of the existing equipment (such as a cutting machine).

The filter (FIG. 8) installed inside the filter (FIG. 6) into which the antibacterial filter material shown in the drawing is charged, the filter of the conventional filter material to be charged and used includes a filter material and a filter material. The offset and partial contact of the contact area and contact time of the diluted aqueous solution were eliminated, and the effect of stabilizing and maintaining the antibacterial activity of the antibacterial filter material was exhibited.

The use of the antibacterial filter makes it possible to reduce the filling amount of the filter material. The cause is a difference in the surface area between the filter media and the particle size used for the filter, which is due to the improvement in the contact area and contact property of the diluted aqueous solution of the filter media. Depending on the amount of aqueous solution,
Only filters can be used.

[0048] The exchangeable filter of the present invention is enlarged or installed in a plurality of units to perform centralized circulation, thereby removing iron in the form of fine powder or iron having large particles in the existing tank installed in each device. It is possible to reduce the time required for work such as stopping the operation of the equipment.

The filter of the drum type filter described in 0025 is carefully selected according to the size of a metal piece or a fine powder discharged from an aqueous solution, and a filter cloth can be used from 5 μm. When the material is introduced, a contact time with the diluted aqueous solution can be obtained, and the antibacterial activity can be easily exhibited, and the auxiliary tank can be installed depending on the amount of the retained solution water. As a result, a result similar to that of the system of the exchange type filter can be obtained.
