  • Patent number: 5165432
    Abstract: Scrap metal chips, which may be oily, wet and dirty and which may be of varying lengths and widths, twisted, curled and cracked, resulting from machining metal articles, are cleaned and dried by passing them sequentially through a washer cylinder, a rinse cylinder and a dryer cylinder. A thread formed of a plate-like metal strip is secured within the interior surface of each cylinder to provide a deep, spiral trough within each cylinder. Each cylinder is rotated so that the chips are moved, in a tumbling motion, along the troughs due to the auger-like thread, from one end to the opposite end. A hot, aqueous washing solution is flowed through the washer cylinder in a direction opposite to the movement of the chips. Similarly, a hot rinse water is flowed through the rinse cylinder in a direction opposite to the movement of the chips therethrough.

  • Patent number: 4988391
    Abstract: A process for treating oil-contaminated debris or like material in particular material to be washed such as mill scale, which is produced in industrial processes, as well as a plant and an apparatus for carrying out the process, are to be improved in such a way as to permit oil to be removed from the industrial material to be washed, in particular mill scale. For that purpose it is proposed that the oil-contaminated material, in particular the mill scale, be introduced into a washing drum and there washed in counter-flow mode in a washing lye with a pH-value of from 12 to 14, preferably 10 to 14, with the material to be washed being lifted at the wall of the drum by means of support surfaces. The washing lye is preferably mixed with about 2% of caustic soda and/or washing is at about 50.degree. C. or a higher temperature.

  • Patent number: 4966177
    Abstract: A system for ultrasonically cleaning tubes includes an elongated cleaning tank adapted to hold a quantity of detergent-containing water and a series of transducers mounted on the bottom wall of the tank in a generally linear arrangement extending between opposite end walls of the tank. The transducers generate ultrasonic cavitational energy within the water in the tank. An inclined upper tube entry ramp supported above the tank guides delivery of tubes in single file fashion into the tank to a reversely inclined middle tube transfer ramp. The inclined middle ramp guides transfer of tubes in single file fashion into the water in the tank and to a lower tube soak ramp having a tube accumulating terminal end. The lower ramp feeds the tubes across the tank within the water and above the transducers therein to its tube accumulating end such that each tube will pass through and be cleaned by the cavitation energy in the water.

  • Patent number: 4062437
    Abstract: An arrangement for surface treating workpieces has a pair of rotary conveyors each rotatable about a respective vertical rotation axis and provided with a plurality of angularly spaced holders each of which can grip a respective workpiece and advance it angularly stepwise through a plurality of respective working stations. In addition each of these holders can be rotated about an axis generally radial of the respective rotation axis for the rotary conveyor for treatment on all sides of each workpiece as it is stepped through the various surface treatment stations. A line conveyor extends tangentially passed the two conveyors and is of the walking-beam type. This line conveyor feeds workpieces to the upstream conveyor so that they then move around the working stations of this upstream rotary conveyor, then takes them off the upstream rotary conveyor and feeds them to the downstream rotary conveyor where they are stepped through the respective working stations of this conveyor.

  • Patent number: 4055246
    Abstract: A ferris wheel type parts washer has its ferris wheel driven by a rotary fluid pressure motor under the control of a variable rate fluid flow control mechanism with means provided for sensing approaching registry of a parts supporting station on the ferris wheel with the parts transfer conveyor for slowing the rotation of the ferris wheel and with means sensing substantial registry of the parts supporting station and the parts transfer conveyor for stopping the fluid pressure motor and locking the ferris wheel in parts transfer registry with the conveyor, such locking means capable of camming the ferris wheel into parts transfer registry should it be slightly out of transfer registry when its movement is arrested. The disclosure shows mechanism for unlocking the ferris wheel and quickly accelerating it to maximum speed.

  • Patent number: 4051805
    Abstract: A system for cleaning, rinsing, coating and drying cans having a circular side wall and a closed end wall at a high rate of speed as the cans emerge from the apparatus by which they are formed. The system basically comprises a washing stage, at least one rinsing stage and a drying stage, with one or more coating stages provided if desired. Each stage is housed in its respective housing and having a can entrance location and a can exit location, with the exit location of one stage being connected to the entrance location of the next succeeding stage by conveyor means. The stages are of a generally similar construction and basically comprise a carrier assembly disposed within the housing for receipt of the formed cans. The carrier rotates about a main longitudinal axis for carrying the cans from the entrance location to the exit location through a circular orbit and in planetary motion, wherein the cans are rotated about their own longitudinal axis as they orbit about the main longitudinal axis of the housing.

  • Patent number: 4009050
    Abstract: An improved transfer device comprised of powered endless surface elements for supporting and moving coated articles in an upright position, such as coated can bodies, from one treatment station, e.g. a coating station to a further treatment station, such as a coating/curing oven. Various parts of the endless surface elements are arranged at selected levels in a trough through which a suitable aqueous medium, e.g. deionized water, is substantially continuously circulated. The height within the trough of this aqueous medium is advantageously controlled relative to the top surface portions of the endless surface elements so that there will be a substantially continuous cleaning of the endless surface elements as excess coating material moves towards and drains from the lower portions of the article being transported while the article is moved through the trough by way of the endless surface elements.
