摘要： A filtration device can be configured to form filter cakes and filtrate by filtering solid particulates from a slurry. Some embodiments of the filtration device can utilize a mechanism that is configured to separate the formed filter cake from a disc sector for subsequent processing of the solid particulates of the filter cake and/or the formed filtrate. Embodiments of the filter device and/or mechanisms of the filter device as well as methods of making and using the same can help provide improvements in operational efficiency for processing operations in which solids are to be filtered from a slurry.

摘要： The present invention relates to a fabric disc filter having a structure for preventing damage to a filter panel. In this regard, an object of the present invention is to provide a fabric disc filter having a structure for preventing damage to filter panel, being capable of preventing the filter panel attached to the filter panel from being torn or being disconnected from the filter frame in the washing process of suctioning and removing foreign matter. To accomplish this object, the present invention provides a fabric disc filter having a structure for preventing damage to filter panel, the fabric disc filter including: a rotary drum; and a plurality of filter segments arranged on an outer circumferential surface of the rotary drum, wherein each of the filter segments includes: a segment frame that is partially open so as to enable inlet of a fluid therethrough, and being configured to discharge the inlet fluid to the rotary drum; a filter frame assembled to the segment frame so as to be positioned on the fluid inlet side of the segment frame; a filter panel provided in the filter frame so as to filter foreign matter in the fluid flowing therethrough; and a rod-shaped stopper provided in the filter panel so as to distribute a load applied to the filter panel in a washing process of the filter panel and couple the filter panel to the filter frame or the segment frame.

摘要： The present invention relates to a filtering panel (100) for a disk filter and a disk filter for water purification, comprising a metal filter cloth (16, 116) such as a stainless steel filter cloth, pre-tensioned in both warp and weft directions and fastened to a frame (10, 110) comprising a peripheral portion (11, 111), which is integral with an inner grillwork (12) and which divides the inner area of the peripheral portion (11, 111) into fields (15, 115). The frame (10, 110) comprises a plastic material reinforced with glass fibers or carbon fibres such as polypropylene loaded with fibreglass in an amount of at least 20 weight percent. Each field of the grillwork (12, 112) has an area not exceeding 10% of the inner area of the peripheral portion (11, 111). The pre-tensioning of the filter cloth (16, 116) in both directions is from at least 20% of the yield stress of the cloth (16, 116). Further the present invention relates to a disk filter comprising said filtering panels (100) and method of making said filtering panel (100).

摘要： The invention relates to a device for the microfiltration, ultrafiltration, or nanofiltration and/or the emulsification of liquids. The device has at least one rotatable membrane medium, which has a filtrate/permeate side or a side facing a dispersed phase and a concentrate/retentate side or a side facing a coherent phase and which can be rotated in a container in order to produce a vacuum on an unfiltered liquid side or the side facing the coherent phase on partial regions of the at least one rotatable membrane medium in the container in small time segments at a frequency of 1-100 Hz. Said container has at least one feed for an unfiltered liquid or the coherent phase, at least one overflow for an unfiltered liquid or an emulsion, and at least one rotatable channel for filtrate/permeate drainage or feed of the dispersed phase, and a suction device, in particular in the manner of a suction strip or nozzle plate. The suction device has at least one suction strip or nozzle plate arranged parallel to the rotatable membrane medium or is such a suction strip or nozzle plate, which is attached at a distance of less than 0.1 to 10 mm from the membrane medium, and thus cleans non-permeating materials collected on the unfiltered liquid side during a filtration process from a surface of the membrane medium, or promotes drop formation of the dispersed phase exiting from a membrane surface on the side facing the coherent phase during an emulsification process. The invention further relates to uses of the device.
