Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a coolant purification device for removing sludge in a coolant used in a grinding machine.

[Prior art]

A conventionally used coolant purification device guides the coolant C flowing out from the grinding machine 1 to the magnetic separator 2, removes the sludge S from the coolant C, and then guides it to the water tank.
etc., to guide it to the grinding machine again.

However, in such a coolant purifying device, although magnetic powder can be removed from the sludge in the coolant, fine sludge such as abrasive grains that are not attracted to the magnet may not be completely removed.

If the coolant containing such fine sludge flows into the grinder again, the sludge will be caught between the object to be ground and the grindstone, resulting in a decrease in the surface accuracy of the product.

[Outline of the idea]

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a coolant purification device capable of removing fine sludge that cannot be removed even with a magnetic separator.

The present invention was devised to achieve such an objective, and is designed to guide the coolant flowing out from the grinding machine to a magnetic separator, remove the sludge in the coolant, and recirculate the purified coolant to the grinding machine. In the coolant purification device, a fibrous filter is provided downstream of the magnetic separator, the fibrous filter having both ends wound around rollers and movable by rotating the roller, and the coolant purified by the magnetic separator. The feature is that the remaining sludge inside can be removed.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic sectional view of an embodiment of the present invention;
FIG. 2 is a perspective view showing the main parts of FIG. 1.

This coolant purification device guides the coolant C flowing out from the grinding machine 1 to the magnetic separator 2, removes the sludge S in the coolant C, then guides it to the water tank, and returns it to the grinding machine using a pump 4 etc. I'm trying to guide you.

In particular, in this embodiment, the coolant C purified by the magnetic separator 2 is transferred to the water storage tank 3.
The fine sludge S contained in the coolant C is removed by this filter 5.

Since this filter 5 is designed to remove fine sludge S, there is a risk of clogging, but in order to prevent this clogging, this filter 5 is constructed of a fibrous filter such as a paper filter. , the paper roll 6 of this paper filter,
Roll it up by 7. In this way, once a predetermined amount of sludge S has been accumulated through filtration, the paper filter can be easily replaced with a new filter 5 by turning the handle 8 and winding up the paper filter little by little, eliminating the need for troublesome filter replacement work. do not have.

Note that the present invention is not limited to the above-described embodiments, and it goes without saying that the filter 5 may be made of a nonwoven fabric or the like in addition to a paper filter.

[Effect of idea]

As is clear from the above description, according to the present invention, the coolant flowing out from the grinding machine is guided to a magnetic separator, sludge in the coolant is removed, and the purified coolant is recirculated to the grinding machine. In the coolant purification device, the coolant purified by the magnetic separator is passed through a filter capable of removing the coolant,
By performing the above-mentioned recirculation, even minute sludge in the coolant can be removed, and purified and clean coolant is always applied to the grinding machine, eliminating the presence of sludge between the grinding wheel and the object to be ground. There is no reduction in surface accuracy due to grinding, which reduces the number of times the grindstone needs to be shaped using a dresser and improves the life of the diamond tool. Moreover, the filter is wound between rollers and can be moved by rotating the rollers, so when clogging occurs with sludge, simply rotating the rollers will remove the fibrous filter. It can be purified with a new part of. This also has the advantage of minimizing the need for troublesome filter replacement.
