Abstract: Disclosed is an air filtration and filter mounting system. The system includes a clean air plenum having a wall with an inlet opening therein. A pair of substantially parallel tension bars are connected to and extend perpendicular to the plenum wall spaced on opposite sides of the plenum inlet. A gimbal plate is slidingly mounted on the tension bars. A filter element is positioned between the tension bars and between the gimbal plate and the plenum wall about the inlet opening. A clamping bar is fixedly connected to the tension bars outward of the gimbal plate and a screw is threadedly engaged with the clamping bar to urge the gimbal plate into clamping engagement with the filter element.

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: A backflushed panel type filtration system is positionable over the flow discharge opening in a dividing wall separating the material collection and clean air flow chamber portion of an air throughflow type particulate collecting device. The filtration system has a filter media section captively retained within an inner peripheral face frame which, in turn, is nested within an outer support frame, this dual frame structure being provided with upstream and downstream peripheral face sealing gaskets. An upstream side flange portion of the outer frame is insertable into the discharge opening and serves to automatically align the filter structure therewith. An internally partitioned clean air flow shroud is removably positionable atop the filter structure and has flange portions which engage the downstream seal gasket and cooperate with side wall portions of the outer filter frame to automatically align the shroud with the underlying filter structure. Front and rear clamping structures are operable to clamp the shroud downwardly against the filter to compress the sealing gaskets and form upstream and downstream peripheral face seals around the filter structure. Cooperating wall portions on the outer filter frame and the shroud prevent clamping over-compression of the inner filter frame. A series of multi-jet type flushing heads are positioned behind the open rear end of the shroud and are operable, via quick-opening valves and a stepper motor, to periodically flow bursts of pressurized air through the shroud and across the filter media to dislodge particulate matter adhering to the upstream face thereof.

Abstract: Pleated paper barrier type air filter elements are cleaned by a reverse air jet cleaning system which includes one or more specifically shaped cleaning air valves 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 elements to clean dust cake from the exterior surfaces thereof. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaning system and provides a larger mass flow of cleaning air. Multiple jet orifice valves may be configured in virtually any geometric shape to provide a desired jet pattern.

Abstract: Disclosed are a compressed air reversed flushing system and sequencing valve. The flushing system includes a compressed air reservoir that is supplied with compressed air by an air compressor. The system includes a plurality of flushing valves connected to the reservoir. The flushing valves are adapted to open sequentially at a selected reservoir pressure. The volume rate production of the compressor is adjustable so as to control the lapse time between flushing events. The sequencing valve includes a valve body having a cylindrical bore. A piston is slidingly disposed in the bore to divide the bore into first and second chambers. An inlet supplies fluid pressure to the first chamber to act on the piston and drive it toward the second chamber. A plurality of inlets to the second chamber receive pressure from the flushing valves. Each second chamber inlet is provided with a valve. The piston includes an operator pin that is operable to open one of the second chamber valves. Axial movement of the piston in the bore results in stepwise rotation of the piston, which in turn causes the operator pin to open the second chamber inlet valves sequentially.
