Abstract: An externally powered, self cleaning strainer incorporating a projectile shield, which is capable of operating for an extended period of time. A suitably shaped, motor, driven, impeller creates a localized, radially outward flow of fluid in the vicinity of the strainer inlet. The projectile shield has a lower surface shaped to deflect fluid to the strainer at a constant velocity, enabling the impeller to eject debris more efficiently. Maintaining a constant flow through the strainer also avoids additional head loss associated with accelerating flow. The self cleaning strainer may also include a brush attached diametrically opposite to the impeller to aid in removing debris from the inlet side of the strainer. The impeller may also be shaped so that when it is swept past the inlet side of the strainer, it causes a localized, reverse flow through the strainer, thereby removing debris particles from within the strainer.
Abstract translation: 一个外部供电的自清洁过滤器，包括一个能够长时间运行的射弹屏蔽。 适当形状的电动机驱动的叶轮在过滤器入口附近产生局部的径向向外的流体流。 抛射体屏蔽具有较低的表面形状以使流体以恒定的速度偏转到过滤器，使得叶轮更有效地喷射碎片。 维持恒定流量通过过滤器也避免了与加速流相关的额外的头部损失。 自清洁过滤器还可以包括与叶轮直径相对的刷子，以帮助从过滤器的入口侧去除碎屑。 叶轮也可以被成形为使得当其被扫过过滤器的入口侧时，其引起局部的反向流过过滤器，从而从过滤器内除去碎屑颗粒。

Abstract: A filter cartridge includes a substantially cylindrical filter media and a pressure relieving structure. The filter media is adapted to allow fluid to pass from an exterior of the filter media to an interior space of the filter media. The pressure relieving structure is disposed at an upper end of the filter media, and the pressure relieving structure opens when a predetermined pressure level is established across the filter media to maintain the predetermined pressure across the filter media.

Abstract: A filter includes filter media and a housing surrounding the media. The housing has an outlet and is sealed such that all fluid flow out of the outlet must first enter the cartridge and pass through the media. The housing has multiple inlet flow paths configured so that fluid impinging on the housing is diffused as it enters the cartridge and is prevented from flowing directly towards the filter media.

Abstract: The invention relates to a filter device with a filter housing (10) and a first filter element (12), arranged therein through which a medium may flow in a given direction and with a bypass device (22). Along with the first filter element (12), a further second filter element (32) is provided, said filter elements (32) are arranged in series, one behind the other, in the direction of flow and, on the bypass device (22) being activated, the further filter element (32), immediately following in the direction of flow, carries out a filtration of the medium. The further filter element thus takes over the main filtration of the medium on actuation and operation of the bypass device as the first filter element is essentially no longer available for a filtration process due to the bypass device.

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 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: A granular bed filter device comprising two gas-permeable walls bounding an annular filter bed disposed in a housing. The walls extend downwardly in a taper together and are inclined upwardly toward the central axis of the filter bed. A nozzle tube projects from above into the housing and has nozzles which are directed against the inner wall of the filter bed. In order to regenerate the dust-laden filter bed, compressed air is blown intermittently through the nozzle tube while at the same time the nozzle tube is set in motion by a motor. The accumulations of dust contained in the filter bed are ejected in agglomerated form through the outer wall and fall down into the region of a discharging conveyor.

A gas deflector and boundary wall between a raw gas duct and a dust chamber upstream from the filter cells form a tapering duct having an outlet passage for coarse dust particles at its narrow end. Either the deflector or the boundary wall is pivoted so that the size of the outlet passage can vary so as to remove coarse dust from the outlet passage. A gas blast for cleaning the filter cells in a direction to move the pivoted element so that the outlet passage is varied and cleaned.
