Abstract:
The present invention provides a high-performance, economically advantageous filter device of a simple, rational construction capable of easily removing foreign matters deposited on a screen and discharging the foreign matters removed from the screen by either manual operation or automatic operation using actuators A self-gush-cleaning filter device comprises a filter casing (1) provided with an inlet passage (a) and an outlet passage (d), a screen (11) disposed within the filter casing (1) so as to slide along the inner surface of the filter casing (1) in the flowing direction of a fluid, a foreign matter ejecting opening (15) being formed between the screen (11) and the inlet passage (a), a drive shaft (4) for driving the screen (11), a screen driving unit (3) for driving the drive shaft (4) so as to move the screen (11) quickly in a downstream direction in which the fluid flows from the inlet passage (a) toward the outlet passage (d) and to move the same slowly in an upstream direction opposite the downstream direction, and an outlet shutoff valve (14) disposed in the outlet passage (d) of the filter casing (1). The screen driving unit (3) is actuated after closing the outlet shutoff valve (14) to move the screen (11). When the screen (11) is moved quickly in the downstream direction, the fluid gushes from the downstream side through the screen (11) into the upstream side, and the foreign matters deposited on the screen (11) are removed from the screen (11) by the force of the gushing fluid.

PURPOSE: To provide an inexpensive fuel filter by forming a filter medium from nonwoven fabric comprising raw material fibers and adhesive fibers, and reducing the number of parts to reduce the number of assembling processes. CONSTITUTION: In the fuel filter comprising a filter medium forming at least two opposed surfaces, an internal space surrounded by the filter medium and storing a liquid and a connection member enabling the internal space to connect with the outside to send the liquid in the internal space to the outside, the filter medium is the nonwoven fabric comprising raw material fibers and adhesive fibers, and the adhesive fibers bond the raw material fibers by melting.
Abstract:
A particle control screen assembly for a perforated pipe used in a well. The particle control screen assembly includes a screen with a first end and a second end. The screen includes a first and a second unsintered woven mesh layer, each layer having a first longitudinal edge and a second longitudinal edge. The cylindrical screen also includes openings sized to prevent passage of particulate material and a longitudinal metal weld adjacent the first and second longitudinal edges of the first and second unsintered woven mesh layers. The longitudinal metal weld secures the edges of the unsintered woven mesh layers together. The particle control screen assembly also includes a weld-compatible metal structure adjacent the first end of the cylindrical screen. A circumferential metal weld between the cylindrical screen and the metal structure bonds a portion of the metal structure and a portion of the cylindrical screen.

PROBLEM TO BE SOLVED: To provide a disposable integrated filter unit 10 suitable for primary and/or secondary purification of medicine fluid. SOLUTION: The disposable integrated filter unit has an inlet 40 and an outlet 60, and is provided with a plurality of filter plates 20n that are inserted into a pair of end plates 24, 26. The filter plates 20n are each provided with a polymer frame structure 28, and a deep inclined filter packet 35 is embedded in the structure 28. The filter plate and end plates form a substantially stationary integrated laminate as a whole, and the fluid flowing in the unit 10 through the inlet 40 passes through the deep inclined packet 35 in each plate 20n substantially simultaneously (namely, parallely) before going out of the unit 10 through the outlet 60.

Abstract:
PROBLEM TO BE SOLVED: To provide a filtering method which can be suitably used for removing cleaned wax from a reactor, while minimizing the adverse effect to the steady-state of the reactor. SOLUTION: In this separation method of a liquid from a mixture of a liquid and a solid, a synthetic hydrocarbon product 6, which is formed by supplying a synthesis gas in a Fischer-Tropsch reactor 4 and reacting it in the presence of a catalyst, is separated from the catalyst particles by a plurality of cylindrical filter 12 having closed edges, for example, passing the synthetic hydrocarbon product 6 through a porous metal cylinder on reactor side (outside), a porous metal cylinder on product side (in side), etc. then the synthetic hydrocarbon product 6 is passed through a filter and the catalyst particles are aggregated outside the filter, and a method of manufacturing the filter 12 is also disclosed.

Abstract:
PROBLEM TO BE SOLVED: To enhance filtering efficiency without the upsizing of the whole device, complicating structure and lowering assemblability, and to keep the filtering efficiency. SOLUTION: A filter element contained in a cylindrical housing 102 with one side opened, and held in the housing with a flow-in side of liquid separated from a flow-out side, is formed by keeping a shape of a filter body 109 formed by stacking and disposing multiple sheet-like filter media 117a, 117b with clearances in a corrugated shape. The filtering efficiency is enhanced by the multiple sheet-like filter media 117a, 117b. The filtering efficiency enhanced by promoting formation of cake layers on the respective filter media 117a, 117b is made to be maintainable. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PURPOSE: To obtain the title filter which is small-sized, inexpensive, and easy to fit by collecting the function of a flow divider, a main filter, and an auxiliary filter into one unit. CONSTITUTION: Lubricating oil flowing in from an inflow port 31 is mostly passed through a clearance between the wall surface of a case 11 and an auxilia ry filtration part 13, and passed into a filter medium 16 from the periphery of a low-density main filtration part 12. Meanwhile, most of the coarse of for eign matter is removed. The oil then passes through the through-hole of a cylindrical body 15, flows into a flow passage 20, and flows out from an outflow port 30. When the lubricating oil after passing through the main filtration part 12 passes through the throttled part 26 of the flow passage 20, a part of the oil is forcibly passed through a high-density filter medium 25 due to the pressure difference from a space part 24 provided at the outside of the auxiliary filtration part 13, and then joined to the flow in the side passage 20. Consequently, the fine foreign matter in the lubricating oil can be efficiently removed, and the space is also reduced. Moreover, the filter can be conveniently fitted into an internal combustion engine without any further working. COPYRIGHT: (C)1986,JPO&Japio
