摘要： A filter system (10) comprising a filter medium (11) for filtering contaminants from a process fluid, having a filtration side on which contaminants collect and a filtrate side from which filtrate flows; a counter-flow generator (20) located on the filtrate side that directs a localized stream of counter-flow fluid (23) from the filtrate side to the filtration side of the filter medium (11) to thereby dislodge the contaminants from the filtration side of the filter medium (11), wherein the localized stream (23) traverses a substantial proportion of the filter medium (11). The filter system (10) optionally further comprises a clearing-flow generator (30) or like means located on the filtration side of the filter medium (11) which clears contaminants from the filter medium (11).

摘要： To separate solid particles from liquids or gas, the liquid or the gas is passed through a coil, formed from one or more threads wound on a carrier. After subsequent washing and drying, the solid which has been filtered out during the filtration process is removed by unwinding the coil from the carrier, the latter consisting of a permeable hollow cylinder closed at both end faces by means of end plates, and provided with a feed orifice.

摘要： A screening system for solid removal includes a housing and a screen positioned within the housing. A flow inlet is operatively connected to an interior chamber defined by the screen. A sump is downstream from the flow inlet for capturing solids that do not pass through the screen. A flow outlet is downstream from the screen in fluid communication with the flow inlet. A moveable cleaning assembly may be positioned either within a perimeter of the screen, around the perimeter of the screen or both. The moveable cleaning assembly is moveable with respect to the screen.

摘要： The present invention discloses a method for self-cleaning filters without having to open the filter housing. Wash nozzles are integrated with the filter housings such that when the filters are clogged, both back-wash and regular washing can be performed with practically no down time. Moreover, without opening the filter housing, the hazardous components of the fluid to be filtered can be contained and dealt with before they escape the filter housing, thereby significantly reduces the environmental impact and harm to the working crew.

摘要： A cleaning device for removing solid impurities from viscous material, in particular molten plastics material, comprising, inside a housing (1), a filter band (5) for separating out solid impurities which can be moved in the longitudinal direction of the housing. The filter band (5) is wrapped around a curved supporting area (7) of a fixed supporting member (3) at an angle of wrap of preferably approximately 180°, and is guided on both sides of the curved supporting area (7) in planar supporting areas (15, 17) which lie tangentially and flush against the curved supporting area (7). To reduce the kinetic resistance of the filter band (5), the curved supporting area (7) and at least partly the planar supporting areas (15, 17) are provided with channels (25) extending in the direction of transport of the filter band (5). The plastic material to be cleaned is supplied via a feeding chamber (23) surrounding the supporting area, and after it has been cleaned, is removed via connecting ducts (27, 35) extending from the channels (25). On the outlet side of the cleaning device the filter band (5) passes through a cleaning solution (67). In this way, the filter band can be reused. The proposed cleaning device is compact and allows for relatively large effective filtering surfaces.
