Filed:

Sep 3, 2003

Appl. No.:

10/654551

Inventors:

Raymond L. Anderson - Walled Lake MI, US
Jason L. Sisler - Cannonsberg PA, US

Assignee:

H.R. Black Co., Inc. - Sterling Heights MI

International Classification:

B01D035/06
B03C001/02

US Classification:

210222, 210396, 210400, 209213, 209226

Abstract:

The magnetic separator has a tank with a pair of dual conveyor chains, spaced apart, at opposite sides of the tank. A plurality of frames with spaced apart magnetic rods are suspended from the conveyor chains in a manner allowing the frames to swivel and always hang vertically as the chains traverse their endless path. The liquid in the tank flows through the frames and ferrous particles are attracted to the magnetic rods. The rods are cleaned and the ferrous particles removed at a wiping station. Each frame has a scraping edge which contacts the bottom of the tank and drags out the non-magnetic particulate which has separated from the liquid.

US Classification:

210297

Abstract:

An apparatus for filtering machine coolant which includes a filtering belt conveyor having a series of bars on the outer surface of the filtering belt conveyor. The filtering belt conveyor is located inside of a tank along with a separate drag conveyor which removes fines that are sprayed off the filtering belt conveyor. There is a partition in the tank between the filtering belt conveyor and the separate drag conveyor.

Raymond L. Anderson - Dearborn Heights MI

Assignee:

H. R. Black Company - Warren MI

International Classification:

B01D 3500
B01D 2902

US Classification:

210 86

Abstract:

In an industrial filter apparatus having a tank with an inlet receiving contaminated effluent from an industrial washing device and a discharge outlet connected to the washing device for recirculating washing fluids, a continuous filter spanning the tank interposed between the inlet and outlet, a continuous drive connected to the filter, a motor connected to the drive and a pump delivering filtered fluids from the outlet to the washing device, an automatic filter media indexer comprises a sensing arm rotatably journaled upon the tank having a contactor engagable with the filter on its downstream side connected by a link and a pull rod to a normally open switch connected to a power source and to the motor. A switch actuator on the pull rod is in registry with the switch, and an adjustable spring normally biases the pull rod. The differential between the liquid levels upon opposite sides of the filter increasing to a predetermined level as it becomes clogged, effecting a proportional deflection of the filter and causing movement of the sensing arm to close the switch.

Inventors:

Raymond L. Anderson - Walled Lake MI

Assignee:

H. R. Black Company, Inc. - Warren MI

International Classification:

B01D 33056

US Classification:

210387

Abstract:

An apparatus for filtering industrial processing liquids is disclosed which includes a tank, a continuous conveyor screen positioned in and defining a loop in the tank, and a continuous filter media placed on an outer surface of the conveyor. The apparatus includes a power operated tractor chain sludge elevator guidably mounted within the tank extending along and frictionally engaging an outer surface return portion of the filter media for effecting a positive upward lift movement of adjacent portions of the filter media with accumulated sludge thereon. The apparatus may also include an apertured horizontal partition in the tank, the filter media sealed over the aperture defining a filtered liquid reservoir chamber positioned below the partition and an unfiltered liquid chamber above the partition, an opened-top vacuum chamber sealed to the filter media and immersed within the filtered liquid chamber positioned within the aperture so as to form a peripheral channel between the aperture and vacuum chamber. An alternate embodiment of the invention includes an open top vacuum chamber with an unfiltered reservoir, a continuous sealing channel upon and surrounding the vacuum chamber, a filter media within the unfiltered reservoir and extending over and sealingly engaging the channel, the channel having a continuous slot in its top defining inner and outer sealing surfaces engaging the filter media. The channel in either embodiment may be connected to a positive or negative pressure source for discouraging the flow of unfiltered liquid into the vacuum chamber.

International Classification:

B01D 33056
B01D 2909
B23Q 1100

US Classification:

210297

Abstract:

A filtration apparatus designed to remove solid contaminants from a liquid includes an endless filtration belt located in a liquid tank, so that liquid flows through minute openings in the belt into a liquid collection box located within the belt envelope. Edge areas of the belt are engaged with annular support walls carried by the tank side walls, such that a continuous seal is provided against migration of contaminants around the belt side edges. Contaminants collecting on the belt surface can be periodically removed by moving the belt across a spray system that dislodges the contaminants from the belt into the tank. A drag conveyor removes contaminants from the tank.

International Classification:

B01D 2909
B01D 3304

US Classification:

210111

Abstract:

An apparatus for filtering industrial process liquids is disclosed herein. The apparatus includes a tank, a continuous conveyor screen mounted within the tank, a partition spanning the tank walls and having an elongated aperture therethrough, and media sealing means upon and surrounding the aperture. One side of the conveyor screen overlies the tank and is guidably retained for sealing engagment with the sealing means, and the other side of the conveyor screen operatively engages a continuous sheet of filter media. The conveyor screen and filter media span the aperture providing upon the underside of the partition an enclosed filtered liquid reservoir and upon its other side an open unfiltered reservoir. An elongated open-top vacuum chamber is supported within the filtered liquid reservoir with its peripheral edge in sealing registry with the conveyor screen and having a first outlet for delivering filtered liquid to a process area. The vacuum chamber also includes a second outlet communicating with the filtered liquid reservoir having a normally closed vacuum release valve.
