It is intended to provide a device.

(Means for Solving the Problems) A plurality of metalworking machines are arranged along the rotation direction of an endless chain conveyor suspended from a filtration device with a lid plate of a filtration tank as a tread plate to operate or operate each metalworking machine. A waste liquid containing chips (magnetic material) discharged during cleaning is introduced into the filtration tank.

A magnet is laid on the bottom of the filtration tank along the direction of rotation of the endless chain conveyor. The magnetic chips contained in the waste liquid are adsorbed on the bottom of the filtration tank on which a magnet is laid, the bottom is suspended on an endless chain conveyor and the moving flight bar is slid to collect the magnetic chips while scraping the magnetic chips. It is conveyed to the vicinity of the end portion and is accumulated and dropped in the vicinity of the end portion to the bottom of a crossing member that crosses the filter tank and the chip transport tank.

Inside the filtration tank, a liquid flow dividing guide is arranged which is directly connected to a metalworking machine arranged around the filtration tank. The bottom of the chip transport tank has the same surface position as the bottom of the intersecting member, and has a rising surface in the chip transport direction, and a magnet is also laid on the bottom. The chip transport tank has a configuration in which a flight bar suspended by the endless chain conveyor rotates along a rising surface extending from the bottom of the cross member in the chip transport direction. Therefore, chips that have accumulated and dropped on the bottom of the crossing member are also adsorbed on the bottom of the chip transport tank, and the chips adsorbed on the bottom of the chip transport tank are scraped off by the flight bar suspended on the endless chain conveyor and rise up. It is thrown from both ends of the rising surface through the surface and is accommodated in a bucket placed below the end of the rising surface.

And are connected. Regarding the crossover between the filter tank 1 and the chip transport tank 3, it is necessary to make the bottom of the chip transport tank 3 deeper than the bottom of the filter tank 1 so as to be crossed stepwise, but the crossover is not necessarily shown in the illustrated embodiment. Of course, it is not limited to such an orthogonal crossover.
Basically, it is supposed that a plurality of metal working machines 4 are installed on the left and right sides of the lid plate of the filtration tank 1, but in some cases, along the lid plate of the chip transport tank 3. May also place the machine 4. Further, the cover plate 1A of the filtration tank 1 can be used as a footboard for walking or as a scaffold for working.

A waste liquid containing chips discharged during operation or cleaning of the machine 4 arranged along the cover plate of the filtration tank 1 is introduced into the filtration tank 1 from the machine 4. A plurality of liquid diversion guides 5 that are directly connected to each machine 4 are installed in the filtration tank, and the liquid diversion guide guides the waste liquid from each machine 4 into the filtration tank 1 and the oil filtered by the filtration tank 1. Is fed back to the machine 4 arranged along the filtration tank.

The bottom of the filtration tank 1 has a bottom surface on which a magnet 6 is laid according to a conventional method. Therefore, the chips contained in the waste liquid introduced into the filtration tank 1 are adsorbed on the bottom surface. Filtration tank 1
The rotary shaft body 7 is mounted on a bearing provided on the chip transport start end side, and the rotary body 9 is mounted on a bearing 8 provided on the crossing member 2. Is an endless chain conveyor 10 that is rotated by the drive rotation of the rotating bodies 7 and 9,
A flight bar 11 is attached to the endless chain conveyor 10 so as to slide on the bottom surface of the filtration tank 1.

The drive device for rotating the rotating bodies 7 and 9 may be provided either on the side of the filtration tank 1 or on the side of the crossing member 2.

On the bottom of the filtration tank 1, the endless chain conveyor 10
The liquid flow dividing guide 5 is arranged and fixed to the filtration tank 1 by an appropriate means with an interval enough for the flight bar 11 attached to the slide bar to slide. It is submerged in the introduced waste liquid.

Further, oil filtered by a pump (not shown) is taken out from the liquid flow dividing guide 5 to the outside of the filtration tank 1 by a take-out pipe 5A and fed back as cutting oil for each machine.

The liquid flow dividing guide 5 referred to in the present specification is, in short, arranged inside the filtration tank 1, and forcibly lays the waste liquid introduced from each machine 4 into the filtration tank 1 with the magnet 6 of the filtration tank 1. A generic term for a device that has a part for approaching the bottom surface that allows the magnetic chips contained in the waste liquid to be adsorbed to the bottom surface of the filtration tank, promotes solid-liquid separation, and removes the solid-liquid separated oil from the filtration tank. Is.

It goes without saying that the non-magnetic foreign matter mixed in the waste liquid also mixes with the accumulated magnetic chips and sinks and accumulates on the bottom surface on which the magnet is laid due to its own weight.

The chips adsorbed and accumulated on the bottom surface of the filtration tank 1 formed by laying the magnets 6 are scraped off by the flight bar 11 and rotated by the endless chain conveyor 10 to the end of the transportation of the chips in the filtration tank 1 and the chips. It is put into the bottom of a crossing member 2 which connects the chip transporting start end side of the transporting tank 3 by intersecting them at right angles.
