The invention is related to a method and vibratory apparatus for the improved solid-liquid filtration of filter cakes, especially for dewatering finely divided thixotropic filter cakes, with the aid of a vibratory apparatus. Further, the invention relates to a filtration apparatus having a vibratory apparatus as described herein, and to the use of the vibratory apparatus for the solid-liquid filtration of filter cakes.

An apparatus for separating mixed together substances of different flowability has a frame structure and a hollow drum with a perforated circumferential surface driven in a revolving manner and mounted on the frame structure. A pressing element lies externally in the region of the circumferential surface of the drum and is driven in a revolving manner, such that the drum and the pressing element form a product intake wedge for the feeding in a product stream, of material to be pressed. The drum and pressing element also form a pressing region. A discharge element is associated with the pressing element downstream of the pressing region in the product stream conveying direction, for discharging residues that remain on the pressing element after pressing. The discharge element is an actively drivable, endless discharge belt for discharging the residues in a discharge direction. A corresponding method is also provided.

A solid-liquid separator for separating a solid phase from a liquid phase in a solid-liquid mixture is provided. The solid-liquid separator includes a basket and filter assembly housed coaxially within a tank such that when the basket and filter assembly rotates the liquid phase moves through the filter of the basket and filter assembly into the tank and is discharged from the solid-liquid separator. The solid phase is retained on the filter of the basket and filter assembly and travels vertically up the filter of the basket and filter assembly where it is discharged from the solid-liquid separator.

The present technology is directed generally to fluid treatment systems. In particular, several embodiments are directed toward filter supports configured to be positioned adjacent a filter belt within a filter belt filtration system. In one embodiment, the filter support can have a longitudinal axis generally parallel to the direction of movement of the filter belt. The filter support can include a plurality of struts spaced apart by a plurality of openings, and at least one of the plurality of struts extends across a portion of the filter support such that a longitudinal axis of the at least one strut is positioned at an angle with respect to the longitudinal axis of the filter support.

A rotary disc filter device includes a rotor rotatable about an axis of rotation, having a plurality of disc-shaped filter members. Each disc-shaped filter member has two walls extending outwardly form the axis of rotation. At least one of the walls has the form of a frustum.

A processing system for processing raw slurry material has a barrel member, at least one transport member, and at least one separator member. The barrel member defines a processing chamber and at least one intermediate opening. The processing chamber defines a pre-processing portion and a separator portion. The at least one transport member is arranged within the pre-processing portion of the processing chamber. The at least one separator member is arranged within the separator portion of the processing chamber and configured to define at least one separator gap. As the barrel member rotates about a longitudinal axis thereof, the at least one transport member transports at least a portion of the raw slurry material through the pre-processing portion of the processing chamber, and the at least one separator member transports at least a portion of the raw slurry material through the separator portion of the processing chamber.

The present invention provides a multi-structure filtration device for filtering, separating, and dehydrating foreign substances in water, the multi-structure filtration device comprising: a filtration tank filled with filtration target fluid inside; a filtration device unit having a cylindrical double drum structure, installed in the filtration tank so that a part of the filtration device unit is submerged in the filtration target fluid, and including two or more filters having different mesh sizes that are respectively wound on an inside and an outside of the filtration device unit, and one or more washing modules washing foreign substances attached to the filter wound on an outside of the filtration device unit. Accordingly, the multi-structure filtration device can have excellent filtration performance by double-filtering the target fluid using two or more filters, can operate in an eco-friendly manner by recycling filtered water and effectively washing the filters using the filtered water without separate chemicals, can increase the durability of the filters, and can reduce the washing and processing cost by reusing the filters.

A centrifugal filtering device includes a centrifugal drum and a rotary filter. The centrifugal drum has a receiving space for accommodating the source fluid. The rotary filter rotatably mounted in the receiving space includes a filter body and a filtrate discharge pipe. The filter body includes a filter cartridge defining a filtrate-collecting space. The filtrate discharge pipe connecting the filter body is communicative in space with the filtrate-collecting space. By rotating at least one of the centrifugal drum and the rotary filter, the source fluid is driven to generate a vortex by a centrifugal force. The centrifugal force drives the source fluid to form a heavy-phase fluid hitting the centrifugal drum and a light-phase fluid approaching the filter cartridge. The light-phase fluid passes the filter cartridge and then reaches the filtrate-collecting space as a filtrate, and the filtrate is exhausted via the filtrate discharge pipe of the centrifugal filtering device.
