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 vibration unit assembly for a belt conveyor has a vibration element, and vibration generator and a connection assembly. The vibration generator is operatively connected to the vibration element for inducing vibrations in the vibration element. The connection assembly connects the vibration element to the belt conveyor so that the vibration element may move relative to the belt conveyor. A contact surface of the vibration element engages a material to vibrate and compress the material as it is transported on the belt conveyor. The vibration element may include a plate or a roller. A method for treating a material involves applying a vibration force and applying a compressive force to compact the material. A method for drying a material involves applying a vibration force to the material to release fluid and applying a compressive force to compact the material.

An apparatus for the separation of dry matter and liquid from a medium includes: a plurality of press rollers and at least one pore roller, at least one separation chamber for receiving the medium, and at least one filtrate chamber defined in cross section by press rollers and the at least one pore roller. The apparatus is configured for establishing a relative negative pressure inside the pore roller interior, such that liquid in the medium is sucked into the pore roller interior, and for roller rotation such that during separation operation dry matter of the medium initially passes between the pore roller and a press roller when transferring from the separation chamber to the filtrate chamber, and subsequently passes between two press rollers, when exiting from the filtrate chamber.

The present invention relates to the field of filtering, more precisely the present invention concerns an apparatus and a method for the separation of dry matter from a medium and the use of said apparatus. One embodiment discloses an apparatus for the separation of dry matter and liquid from a medium, comprising a plurality of press rollers, a separation chamber for receiving the medium and defined, in cross section, by the press rollers, and at least one chamber filter located inside and enclosed by the separation chamber. The apparatus is preferably configured such that a negative pressure can be established in said chamber filter(s) relative to the separation chamber such that liquid in the medium can be sucked into the chamber filter(s) and dry matter in the medium can pass between corresponding press roller.

A sludge dewatering system includes: a concentration apparatus that concentrates sludge while conveying the sludge on a top surface of a filter body; and a dewatering apparatus that subjects the sludge discharged from the concentration apparatus to pressure dewatering. The concentration apparatus includes: a filtering unit that subjects the sludge, which has been added with a first chemical agent, to gravity filtration; a chemical feeder that adds a second chemical agent to the sludge conveyed in the filtering unit; and a moving mechanism that moves the sludge, which has been added with the second chemical agent, in a direction intersecting a conveyance direction of the filter body.

A pair of filter cloths is wound around a first roll a plurality of times by being wound around the first roll, then being wound around a second roll to return to a space between the first roll and the pair of filter cloths wound around the first roll, and being wound around the first roll again. The pair of filter cloths wound around the first roll the plurality of times applies a pressing force to the first roll.

The disclosed technology regards a wet dust extractor system with a water/solids separator for filtering slurry from the extractor into residue cakes and filtrate water, and related methods of removing dust from an industrial environment and dewatering resulting sludge. The wet dust extractor system has an air inlet, an impeller fan, and an extraction panel. Water is injected at the inlet of the fan impeller, where it is spun with the incoming dust laden air; the resulting slurry then passes to the extraction panel, which removes the slurry from the system by means of a discharge sump. The slurry then is pumped or otherwise delivered to the separator for filtering slurry into residue cakes and filtrate water. The separator includes a frame supporting a plurality of rollers supporting a filter media belt, a plurality of blades and wipers for cleaning the rollers and removing excess filtrate water and cake material, and an inlet water manifold to distribute slurry water uniformly on the filter media belt. The frame supports a filter bed, with a slurry receiving area having a perforated panel at its base, for receiving, pre-filtering and moving the slurry through the separator, and a filter bed collection tub with an exit aperture for collecting and delivering filtrate to a water holding tank. The filter media belt traverses the plurality of rollers, through and about the filter bed, supported along a portion of its path by the perforated panel. Both a residue cake bin and a clean water holding tank may be provided with the system to collect residue and filtrate water, respectively, for re-use or disposal.

An apparatus for performing an operation on a fluid material to separate liquid from solid matter within the fluid material The apparatus comprises a belt structure movable along a path. The belt structure comprises a belt portion adapted to be assembled into a movable tubular structure within which at least part of the operation is to be performed. The tubular structure is permeable to liquid for separation of liquid from solid matter within the fluid material. The tubular structure is continuously assembled at one end thereof and continuously disassembled at another end thereof during movement of the belt structure. The path includes a descending portion along which the assembled tubular structure passes, the descending portion being inclined whereby at least some of the solid matter within fluid material in the tubular structure is caused to move downwardly along the descending portion under the influence of gravity to facilitate cleaning of the permeable tubular structure.
