Description of the Related Art In a cutting oil filtering device having the above-mentioned structure disclosed in Japanese Utility Model Laid-Open Publication No. 64-4540, a plurality of air streams are provided above a filter net portion of a rotary cylinder relative to the filter net portion. A pipe with an outlet opening is arranged in parallel with the center line of the rotary cylinder, and compressed air blown out from the air outlet is blown against the filter net to prevent the filter net from being clogged by chips. However, if a large number of cutting oil filtration devices are used in one factory, a large amount of compressed air will be used, and the pressure in the factory air line will decrease. There is a problem that the equipment is hindered.

As a result, a large amount of air is consumed, but if a part of the cutting oil in the storage tank that has been filtered by the cutting oil filtration device is pumped up and blown against the filter net, the cutting oil that is liquid Since the density of the air is higher than the density of air, the momentum is large and not only can clogging be prevented effectively, but also there is an advantage that it does not hinder the equipment using the air line, but the cutting oil is sufficient. However, there is a problem that chips that are not removed are removed from the filtration device.

It adheres and rises with rotation, and the other part falls near the lowest position of the circular cross-section of the rotating cylinder due to gravity, moves along the spiral guide blade toward the open end, and in the meantime chips The cutting oil adhering to the filter net passes through the filter net in the filter net area and flows down into the storage tank, or the cutting oil that could not pass through the filter net due to clogging is the slope formed by the lowest position of the circular cross section In the filter net region where the cutting oil is blown, the cutting oil is transmitted through the filter net together with the cutting oil blown into the filter net and entering the inside of the rotary cylinder into the storage tank. The cutting oil remaining in the chips sent to the non-filter net region flows down toward the filter net region along the slope formed by the lowest position of the circular cross section.
