Abstract:
A self-cleaning assembly comprising an enclosed casing 1 with a movable piston 31 and filters 32,33 therein. The preferred assembly has a casing 1 with a dirty water inlet 5, a first outlet 6 for clean filtered water and a second outlet 7 for the removal of sludge from the casing. The filter assembly is constructed and arranged to provide, in its normal operating mode, a liquid flow path through the filter 32,33 in a first direction between the dirty water inlet 5 and the clean water outlet 6 and, in a cleaning mode, to provide a liquid flow path in a second direction between the dirty water inlet 5 and the sludge outlet 7. In the cleaning mode, the movable member 31 compresses the filters 32,33 during the liquid flow in the second direction and contaminant is released therefrom for removal from the filter assembly via the second outlet 7. In an alternative embodiment, the sludge outlet 7 is omitted and sludge is removed from the casing via the outlet 6.
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 (21a). 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 liquid filtration apparatus comprises a filter body (1) housing a filter module (3) and having an inlet port (6) for the liquid to be filtered and an outlet port (10) for the filtered liquid. The filter module (3) consists of a compact mass of substantially parallel elongate fibers (28) oriented axially in a cylindrical casing. An inflatable band surrounds the fiber mass and is located between the fiber mass and the inner wall of the cylindrical casing.
Abstract:
A filtering method and apparatus including a chamber having an inlet and an outlet and a mass of fibers interposed between the inlet and outlet and contained between a perforated base and piston. Structure is provided for reciprocating the piston relative to the base during backwash operation.
Abstract:
A tangential flow filtration module includes plural plate units connected in sequence. Each of the plate units includes a main body, a first combing portion, a second combing portion, a first flange and a second flange. The main body has a first side surface, a second side surface and a through hole. The first side surface is opposite to the second side surface, and the through hole extends from the first side surface to the second side surface. The first combing portion and the second combing portion are disposed on the first side surface and the second side surface respectively. The first flange and the second flange respectively protrude from the first side surface and the second side surface and respectively. The first combing portion of one of the plate units is combined with the second combing portion of another one of the plate units, so that a sieving structure.
Abstract:
Embodiments of the invention provide a filter for use in filtering a fluid slurry that includes particles of varying size, such as pool water including debris. The filter is in electrical communication with a sensor and includes a housing having an inlet to receive the fluid slurry, an outlet, and an internal chamber. An actuator can be coupled to the filter media to move at least a portion of the filter media to vary a dimension of the pores. The filter also includes a controller connected to the actuator that is capable of receiving a signal from the sensor and controls the actuator to change the dimension of the pores based on the signal.
Abstract:
Disclosed are a free-traction filtration device capable of carrying out a massive filtering process and continuous automatic operation, and a method of controlling the same. The free-traction filtration device includes a plurality of filter units each consisting of some sheets of stacked plate filters; top and bottom plates configured to support the filter units at upper and lower portions thereof so as to maintain positions of the filter units, the filter units being circumferentially arranged between the top and bottom plates; a spring configured to resiliently support the top and/or bottom plates in a horizontal state; and an operating unit configured to transmit vibration to the filter units arranged between the top and bottom plates.
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 by a cylinder, an endless track pin, and a support to be rotatable together with the cylinder; a fiber yarn bundle support rod inserted into the endless track to be connected to the endless track; a fiber yarn bundle, one end of which is fitted with and supported by the fiber yarn bundle support rod; a fiber yarn bundle support net for supporting the fiber yarn bundle while being attached to an outer peripheral surface of the fiber yarn bundle; a cleaning separator fixedly installed at an upper outer side of the cylinder; and an ejector installed on an upper outer side of the cylinder.
