Abstract:
A filament filter for water treatment or air cleaners and a filtering apparatus mounted with the same. In particular, a filter having a filament as a filtering material and a filtering apparatus mounted with the same. A filter, which is totally different from a membrane filter or a filter having a net-like construction, is provided in which filaments comprising a synthetic resin material, metallic material or wood material are integrally formed with upper and lower frames of the filter, and a filtering apparatus using the filter is also provided. With the filter of the present invention used in a water treatment device or air cleaner, easier, less expensive and more efficient treatment can be achieved than with a conventional filter. In addition, the filter is easy to clean and replace, and is economical.
Abstract:
A lift type pore-controllable fiber filter includes a filter tank, a strainer coaxially formed as a porous tub in the filter tank, extending to an outside of the filter tank at a bottom thereof to communicate with a treated water drain pipe, and having a piston guide recessed in an axial direction at an upper portion thereof, a lifting driver including a cylinder and a piston, an upper filter material fixing plate having fixing means, fixed to the piston above the strainer, and working in collaboration with reciprocation of the piston, a lower filter material fixing plate having fixing means and fixed below the strainer, and at least one fiber filter material fixed to the fixing means of the upper and lower filter material fixing plates at upper and lower ends thereof respectively, and forming filtering pore layers on an outer circumference of the strainer.
Abstract:
PROBLEM TO BE SOLVED: To provide a filter capable of suppressing push-out from being generated by forming a density inclination in the filter without decreasing a cross-section in a high-density portion of the filter. SOLUTION: A cylindrical hard spot 21 is provided at the outer periphery of a filter element 20 to regulate the deformation of a fuel flowing direction in the filter element 20, and press compression is performed from a downstream side end 24 to an upstream side end 23 of the filter element 20 with a retainer 40. This allows a density inclination to be formed in the filter element 20 to equalize a collected foreign matter distribution in the filter element 20, thereby enabling the system to minimize an increase in pressure drop and collection efficiency deterioration caused by an increase in a collected amount of the foreign matter without decreasing the path cross-section of the fuel that is the cross-section of the filter element 20. Therefore, the filter capable of suppressing the generation of the push out may be provided by forming the density inclination in the filter without decreasing the cross-section of the high density portion in the filter.

Abstract:
Disclosed is a pore adjusting filtering apparatus including: a cylinder having a plurality of holes and in which a screw is rotatably installed; an endless track coupled to an outer peripheral surface of the cylinder; a fiber yarn bundle support rod inserted into the endless track; a fiber yarn bundle fitted with and supported by the fiber yarn bundle support rod; a fiber yarn bundle support net for supporting the fiber yarn bundle; a cleaning separator fixedly installed at an upper outer side of the cylinder, for supporting the fiber yarn bundle support net; and an ejector installed on an upper outer side of the cylinder, for removing contaminants by ejecting water to the fiber yarn bundle while the fiber yarn bundle and the fiber yarn bundle support net are separated from each other.
Abstract:
A filter device includes a casing having an inlet for introducing fluid and an outlet for discharging fluid, and a filtering element disposed between the inlet and the outlet. The filtering element has an outer circumference face restricted from being deformed in a fluid flowing direction. The filtering element has an upstream end face on an upstream side in the fluid flowing direction, and a downstream end face on a downstream side in the fluid flowing direction. The filtering element is configured to be compressed toward the upstream end face by pressing the downstream end face.
Abstract:
A high rate, upflow filtration system is described in which a compressible, fibrous lump filtration media is compressed to adjust the porosity and collector size of the media in the bed and to provide a porosity gradient within the bed proceeding from more porous to less porous in a direction opposite to the flow of fluid so that filtration proceeds in a direction from a more porous to a less porous filter bed. Larger particles are removed by the more porous media and successively smaller particles are removed as the filter bed becomes less porous. The system is capable of reducing the turbidity of influent municipal wastewater from about 8 NTU to about 2 NTU at a wastewater flow rate of from about 820 to 1230 L/m2·min (20 to 30 gal/ft2·min), at a bed compression ration of from about 15 to 40 percent, and at a backwash rate of from about 1 to 6 percent based on the total wastewater passing through the filter.
