Abstract: A self-cleaning impingement type air filter unit is mounted on a flexible elastomeric support member comprising an end wall of a filter housing exposed to the pressure differential between the interior housing chamber and the ambient pressure of the clean air discharge conduit. A standard pleated paper type porous media filter element is mounted on the flexible wall member and includes a support plate on which a mechanical vibrator is mounted whereby the complete filter element is mechanically oscillated to dislodge accumulated material on the surface of the filter media. The filter support structure includes a mounting flange which is adapted to be supported on a filter housing by yieldable springs which permit movement of the entire filter element and support structure to function as a pressure relief valve to limit the pressure differential across the filter housing. The system is particularly adapted for use with bulk material conveying systems operating at relatively low conveying air pressures of approximately 15 psig.

Abstract: An improved rotary joint construction is produced by eliminating the external drive mechanism used for installing and removing such joints. An internal drive mechanism is provided within the bearing area of the stem which does not alter rated flow volume and which does not add to the length of the stem. The internal drive mechanism comprises a socket in the end of the stem which allows the joint to be installed or removed without using special tools. A more compact shorter joint can be produced without reducing the distance between the seals and without reduced rated flow volume and without reducing the contact area of the between the stem and barrel. Alternately, a joint with substantially increased bearing contact area and a longer barrel can be produced without increasing the stem installation clearance height and without reducing the interseal spacing flow passage geometry and subsequent rated flow volume. The longer bearing surface and a longer barrel provides longer life by reducing the maximum possible gap in the seal area as a result of misalignment caused by side loading of the barrel and reduces wear. The increased length of the bearings and barrel permit a substantial increase in operating pressure without undesirably extruding the seals.

Abstract: Disclosed is an air filter apparatus having a separator chamber formed by a housing in which a barrier type filter element is mounted to an annular backflushing air reservoir or manifold having a bore therethrough on a unitary support member which may be removed from the housing through the manifold bore. Reverse flow filter element flushing air discharge heads are mounted to the manifold and disposed over the filter element clean air discharge chambers and are movable away from the manifold bore so that the filter element may be inserted into and removed from the separator chamber. The filter element support member is secured to the manifold by pins which support a flange for movement relative to the housing to relieve pressure differentials across the filter element to prevent rupture of the element or minimize the hazard of failures elsewhere in the filter system.

Abstract: Single and multiple porous media impingement type air filter elements are disposed in filter housings which provide access to the filter elements from top opening doors or plenums in the housing for service or repair of the elements. Housing sections defining the plenums are provided with mechanism to lift and swing the housing sections clear of the filter opening, and the housing sections are movable to relieve excess working pressure differentials across the filter element. In two embodiments the filter elements are each in sealing engagement with a shield which is also sealingly engaged with a top wall or door of the filter housing to minimize contamination of personnel servicing or replacing the filter elements. Clean air is discharged through a downwardly extending clean air flow tube into a discharge plenum or chamber and particulate material separated from the air flow stream falls into a material collecting hopper portion which may be defined in part by a sloping wall separating the clean air flow chamber from the particulate material collection chamber. Filter element backflushing air control valves may be located in the bottom of the filter housing to enhance the accessibility of the filter elements from the top of the housing and to minimize overall height of the filter apparatus.

Abstract: A porous media air filter unit for a power sweeper includes an impingement or barrier type filter element mounted on a combination support plate and clean air discharge plenum which redirects the filtered air flow at right angles relative to the central axis of the filter element. Multiple reverse jet backflushing air discharge manifolds are mounted generally alongside the filter element and at the outlet of the clean air discharge plenum for directing plural jets of reverse flow filter cleaning air into the plenum for periodically cleaning the filter element. Reverse jet cleaning air is supplied to a supply manifold by a compressor onboard the power sweeper. The supply manifold forms a wall of a housing forming a clean air chamber and supports an array of reverse jet air discharge manifolds and pilot operated control valves. The clean air plenum may be provided with interior partitions to separate the plenum into a plurality of separate flow passages for conducting clean filtered air in one direction and reverse jet cleaning air in the other direction to maximize cleaning air energy for dislodging particulate material from the filter element. The filter element includes removable divider plates for dividing the element clean air chamber into plural chamber segments.

Abstract: A reverse air jet cleaning system for impingement or porous media type air filter elements includes one or more specifically shaped cleaning air manifolds or heads in which a plurality of jet nozzles or orifices are arranged in a predetermined pattern to provide a totally enveloping air jet which is discharged into a flow tube immediately downstream of the clean air flow chamber of a generally tubular filter element. The jet pattern provides a temporary pressure seal within the flow tube and entrains a substantial amount of ambient air into the reverse flow jet to thoroughly flush or flood the filter element to clean the dust cake from the exterior surface of the element. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaning system and provides a larger mass flow of cleaning air to thoroughly flush the surfaces of the filter element. The multiple jet orifice heads or manifolds may be configured in virtually any geometric shape to provide the desired jet pattern and are not limited to use in conjunction with cylindrical tubular type filter elements.

Abstract: An air filter unit has a housing including a plurality of separate filter element chambers disposed side by side and each including openings to an elongated air inlet chamber. Each of the filter element chambers includes a porous media filter element for receiving a portion of a material laden air flow stream entering the housing in such a way that the lower velocity portions of the flow stream are diverted into the respective filter element chambers and forced to flow in a vortical manner to provide inertial separation of material prior to flow of air through the filter elements. The inlet air flow is directed against a wall of the inlet chamber at the end opposite the inlet end of the inlet chamber so that higher velocity portions of the inlet air flow stream impinge the wall to separate particulate material entrained with the higher velocity portion of the flowstream. Separate hoppers in the inlet chamber and the filter element chambers are in communication with each other through a one way door which conducts separated material from the inlet chamber through one or more of the filter element chambers and through a second door for discharge to the exterior of the housing.

Abstract: A conveying and collection system adapted for drilling rigs for conveying drill cuttings entrained with a bailing air flow stream emanating from the drillhole includes a generally tubular head fitted around the drillhole having a flow deflecting surface portion adapted to deflect the flow stream of drill cuttings into a conveying enclosure whereby velocity reduction and change of direction of the flow stream will separate relatively coarse cuttings. A mechanical conveyor may be disposed in the enclosure to convey the cuttings to a point remote from the drillhole. The head may be extended and retracted with respect to the drill rig deck plate by actuators controlled in accordance with the conduction of bailing air to the drill stem. One embodiment of the head comprises an enclosure formed by overlapping helical convolutions of a flat spirally coiled band. The head may be provided with retractable gate members remotely actuated to move clear of an opening in the head which is of sufficient size to permit movement of drill stem coupling members and/or the drill bit through the head during drilling operations. A filter unit has a plurality of separate filter element chambers in which are disposed porous media filter elements arranged side by side along the flow path of a bailing air flow stream entering the filter unit housing so that the lower velocity portions of the flow stream are diverted into the filter element chambers and forced to flow in a vortical manner to provide inertial separation prior to flow through the filter elements. A suction pump on the filter unit is operable to vary its inlet volumetric capacity to provide a partial vacuum condition throughout the collection system to minimize leakage flow of dust laden bailing air out of the system.
