Abstract:
The present invention provides a gravity fiber filter, comprising: a filter tank placed in a portion of a large amount of running water; at least one unit filter disposed in the filter tank; a filtered water collecting tank disposed in a lower portion of the filter tank; a discharging pipe extended from the filtered water collecting tank to the height lower than a influent inlet of the filter tank, so that the height of the extended discharging pipe is defined as a height of starting filtration; a sensor; a air inflow pipe through which a backwash air flows in from outside to a lower portion of the filter tank; a control means controlling the operation of filtering and backwashing; and backwash water discharging pipe.
Abstract:
In a high speed upward flow filtration apparatus, an upper perforated panel for receiving a fibrous lump is secured to a circumferential side plate for receiving the fibrous lump. A lower movable perforated panel for receiving the fibrous lump is vertically moved by a vertical motion cylinder, and fitted into the circumferential side plate for receiving the fibrous lump under the upper perforated panel for receiving the fibrous lump. A filter layer is formed by filling the fibrous lump between the upper perforated panel for receiving the fibrous lump and the lower movable perforated panel for receiving the fibrous lump. An unfiltered water supply diffuser is provided under the lower movable perforated panel for receiving the fibrous lump. The lower movable perforated panel is raised by the vertical moving cylinder to form a dense and uniform filter layer and to implement a high performance filtration.
Abstract:
Ein Filter 2, das insbesondere für wasserführende Haushaltsgeräte dient, weist eine elastisch verformbare Filterschicht 20 auf. Die elastisch verformbare Filterschicht 20 umfasst mehrere offene Ausnehmungen 22. Hierbei ist die elastisch verformbare Filterschicht streck- und/oder stauchbar. Ferner ist ein wasserführendes Haushaltsgerät 1 mit solch einem Filter 2 angegeben. Durch das Strecken oder Stauchen der elastisch verformbaren Filterschicht 20 ist eine Durchlässigkeit des Filters 2 veränderbar. Dabei ist die elastisch verformbare Filterschicht 20 mittels einer Betätigungseinrichtung 10 mit einer Kraft beziehungsweise einer mechanischen Spannung beaufschlagbar, um die elastisch verformbare Filterschicht 20 zu strecken und/oder zu stauchen.
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:
The pore size controllable filter can separate and remove effectively the suspended solid and eliminate rapidly it captured by the device. The filtering materials ( 21 ) are built on the upper filtering material holder ( 23 ) and the lower filtering material holder ( 24 ) of radial type facing each other at a certain distance in the filtering tub ( 2 ), forming a filtering layer ( 21 a). According to the direction and the degree of rotation of the upper handle ( 28 ) connected to the upper rotation axis, the filtering materials ( 21 ) come together to the center along the upper filtering material holder ( 23 ) and the lower filtering material holder ( 24 ). Then one side or both sides are twisted in opposite directions and concentrated around the perforated pipe ( 22 ) located at the central axis or restored to the original state. Accordingly, the size of the pore created between the filtering materials ( 21 ) can be adjusted, enabling to conduct filtering and washing operations at a proper level.
Abstract:
A cartridge (7) for removing contaminants from a liquid comprises (a) a central inlet or outlet, (b) a circumferential outlet or inlet for radial flow through the cartridge and (c) a resilient, helically coiled plate (8) permeable to liquid. One edge of the plate is secured at or near the central inlet or outlet, the other edge is secured at or near the circumferential outlet or inlet and means is provided for tensioning the plate. The cartridge may be used in a filter. It may be modified by adding a fibrous layer to the coiled plate. This renders it suitable for use as a coalescer.
