摘要:
A recovery apparatus comprising a running member which runs between a first position where the member is immersed in the liquid stored in a reserve tank and a second position where the member projects upwards from a surface level of the liquid, and a bucket which is secured to the running member and which scoops the floating matter floating at the surface level of the liquid, while moving from the first position to the second position. The bucket comprises a bucket body which has an opening for allowing the liquid containing the floating matter to flow in, and which gradually narrows downwards from the opening, partition plates which extend downwards from the opening and face each other and which block the floating matter flowing from the opening, and discharge ports which are made in the bucket body and open at a position lower than the opening.

A cyclone-type separator comprises a hollow cylindrical main body in to which liquid containing foreign matter is introduced, a clean room provided in an upper end of the main body, a communication pipe which connects the clean room to an interior of the main body, and a porous separating pipe arranged in the clean room. As the liquid swirls in the main body, an eddy stream is generated. A columnar air layer and a clean liquid layer are formed, both aligned with the centerline of the eddy stream. The air layer and the liquid layer are guided via the communication pipe into the separating pipe. At the bottom of the clean room, there are provided a first reservoir for storing the liquid coming through the separating pipe, a second reservoir for storing the liquid flowing from the first reservoir, and a coolant outlet port for discharging the clean liquid.

A chip treatment device 100 includes a box-shaped housing 110, and an upper surface panel 112 of the housing is connected to a sloped portion 114. The interiors of the housing 110 is divided into upper and lower areas by a partition panel 130, and to the areas are provided a first cutting fluid bath 150 and a second cutting fluid bath 160. Chains 240 stretched between driving sprockets 210 and chain guide units 230 are equipped with scraper units 250 moving in the direction of the arrow. The chips coming in from an entrance opening 180 is separated from cutting fluid while being conveyed on the separation panel 130. First and second filter units 170, 300 filter said cutting fluid.

A filter apparatus includes a mesh filter consisting of a flexible sheet having a smooth surface and a multiplicity of through-holes and formed into a cylindrical configuration. The leading edge of a scraper is brought into abutting contact with the outer surface of the cylindrically formed mesh filter, or two scrapers can be provided on the inner and outer surfaces of the mesh filter with their leading edges abutted against these surfaces. Provided within the mesh filter is a support shaft serving also as a discharge pipe. The discharge pipe discharges clean oil filtered by the mesh filter, and the support shaft rotatably supports the mesh filter. The cylindrical mesh filter is disposed in a tank for accommodating cutting oil or abrasive oil containing solid foreign matter such as cutting chips or abrasive grains. The mesh filter is rotated on the discharge pipe/support shaft by a drive mechanism. The oil containing the solid foreign matter is passed through the cylindrical mesh filter from the outer to the inner side thereof so that the foreign matter in the oil is trapped by the through-holes. The foreign matter thus trapped is scraped off the mesh filter by the scraper or scrapers as the mesh filter rotates.

A contaminated fluid recovery apparatus includes a sludge removal mechanism having a dirty tank, a conveyor, and a magnetic drum which is arranged in the fluid circulating section. The contaminated fluid recovery apparatus is provided with an overflow tank. The overflow tank has a function to keep a fluid surface of the dirty tank in a position higher than the fluid circulating section and the magnetic drum. The magnetic drum is located horizontally between a lower portion and an upper portion of the conveyor. The conveyor scrapes out chips deposited on a bottom portion of the dirty tank toward an exit section. A scraping member, which is in contact with the magnetic drum, drops sludge attracted to the magnetic drum toward the lower portion of the conveyor.

A paint booth is provided with a purifier. The purifier includes a water tank, pump, water cord formation mechanism, sludge removal mechanism, exhaust mechanism, and barrier member. The water cord formation mechanism includes a water case located in an upper part of a spray chamber. A large number of nozzles are formed in a bottom wall of the water case. Each nozzle includes a tubular portion, the inside diameter of which is reduced downward from an inlet, and a circular outlet. Water falling in straight lines from the outlet forms a large number of parallel water cords. Paint mist is collected as air containing the paint mist contacts the water cords. An exhaust chamber is formed on the back side of the barrier member.

A filtration device is provided with a filter tank, filter media unit, and magnet. The filter media unit includes a filter media accommodation case and a large number of magnetic granular filter media. The magnet is movable between first and second positions. In the first position, a magnetic field is applied to the magnetic granular filter media, so that the magnetic granular filter media magnetically attract one another. In the second position, magnetic attraction between the magnetic granular filter media is canceled. The filter media accommodation case includes a nonmagnetic mesh member of a nonmagnetic material and magnetism intensification plate of a magnetic material. When the magnet is in the first position, the magnetic granular filter media and nonmagnetic mesh member are located between the magnetism intensification plate and the magnet.
