  • Publication number: 20110023279
    Abstract: The present disclosure relates generally to a movable aqueous- and solvent-based parts washer used to wash grease, oil, dirt, and other debris from mechanical parts using an cleaning solution, and more particularly, to a parts washer with a movable sink and movable lid pivotally connected to a hollow housing for facilitating the access within the housing for the replacement and maintenance of a cleaning solution reservoir. The third-generation washer is made of molded reinforced polymer in a shell configuration around a tilting reservoir. A pump is also pivotally connected below the sink to retract the pump during change operations of the cleaning solution reservoir. The device includes a molded sink with basin and reinforced pan with an interface to control the release of fumes between the sink and the pivoting lid.

  • Patent number: 7740711
    Abstract: A parts washer including magnets located near a pump inlet to collect metallic particles suspended in the cleaning fluid; a casing to protect the pump mechanism from impact during handling; the pump oriented horizontally to take advantage of the separation of the cleaning fluid in successive vertical layers; two liquid level sensors to measure the level of the cleaning fluid in the reservoir; an evaporation control plate located at the interface between the reservoir and the receptacle of the reservoir to confine the vapor portion of the cleaning solution; protective handlebars placed next to the controls of a control module to protect the device from impact; and a pump motor control to provide a low flow rate of cleaning fluid using a pump without a variable regulator.

  • Publication number: 20080210260
    Abstract: The present disclosure relates generally to a multipurpose parts washer used to remove grease, oil, and dirt from mechanical parts, and more particularly, to an apparatus for washing parts within a single housing having an automatic cleaning portion, with a first cleaning chamber for spraying parts, a second cleaning chamber for soaking and agitating parts, and a manual cleaning portion. The multipurpose parts washer includes three cleaning portions. All portions use cleaning solution from a single pump, a reservoir portion to collect and store the important volume of cleaning solution and debris from the washing process, a single controller interface operated from a display, and a thermal energy source for heating the cleaning solution.

  • Patent number: 7368054
    Abstract: A separator to separate oil and debris from an aqueous fluid includes a container with a cover, the top portion of which includes a control panel access door. The separator draws an aqueous fluid with one or a plurality of skimmers that float on the aqueous fluid inside one or a plurality of corresponding reservoirs. When the separator is operating, the surface portion of the aqueous fluid is drawn into each corresponding skimmer hose and transferred to the separator by a pickup hose. The separator separates oil, debris and any sludge that may be in the aqueous fluid to provide a substantially filtered aqueous fluid. The substantially filtered aqueous fluid is then returned to the reservoirs through an exit hose.

  • Publication number: 20070181472
    Abstract: Separating apparatus, for separating a substance from a liquid on which the substance can float, comprises: a separation chamber; an inlet adapted to convey a supply comprising the substance and the liquid into the separation chamber; and an outlet adapted to convey liquid collected in the separation chamber out of the separation chamber. The inlet is arranged such that, in use, the supply emerging from the inlet into the chamber is directed upwardly into the chamber, and the apparatus further comprises venting means arranged to convey gas out of the chamber. The apparatus may further comprise a floating pick up connected to a pump for pumping the supply to the separation chamber. In certain examples a non-floating pick up is used, comprising an elongate hollow body with a pick up inlet mouth in the form of a vertical slot extending along a length of the body.

  • Patent number: 7128075
    Abstract: An apparatus for washing parts includes a cleaning chamber including a spray portion and a reservoir portion. The spray portion includes a support for the parts and a spray bar having at least one orifice for distributing a cleaning solution. The reservoir portion stores and collects the cleaning fluid. A thermal energy source adjusts and maintains the operating temperature of the cleaning solution in the reservoir portion. The thermal energy source retains a transfer fluid and includes a heater for adjusting a temperature of the transfer fluid. A conduit extends through the thermal energy source and defines a passageway for the cleaning fluid. A pump draws the cleaning fluid through the passageway and discharges the cleaning solution through the spray bar, such that the operating temperature of the cleaning solution is increased.

  • Patent number: 7040161
    Abstract: A parts washer including a receptacle positioned on a reservoir for cleaning liquid having a drain opening and a module which engages a portion of the reservoir in the cleaning liquid for adjusting the temperature of the cleaning liquid and circulating the cleaning liquid into the receptacle. The module includes a heating element, a sensor and pump. An enclosure houses a temperature controller which displays the temperature of the cleaning liquid and a low liquid level condition. A bridge thermally links the heating element to the sensor so that the sensor normally generates a signal representative of the temperature of the cleaning fluid unless the level of the cleaning fluid is disposed below the sensor.
