摘要： 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.

摘要： 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.

摘要： The disclosed technology regards a water/solids 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. The present invention also regards a method for separating filtrate water and cake residue from slurry, using the water/solids separator herein described, by continuously providing slurry through the inlet water manifold, while powering the gear motor to cause rotation of the drive roll, resulting in rotation of the filter media about the plurality of rollers. By this method and the disclosed technology, a portion of the water from the slurry is removed, through the filter media belt and the perforated panel.

摘要： A dewatering system for removing liquids from feed material comprises a pre-processing stage separator, an output roller press, and a control system. The pre-processing stage separator processes the feed material at a pre-processing rate to obtain a pre-processed mat, where the pre-processed mat contains less liquid than the feed material. The output roller press processes the pre-processed mat at an output rate to obtain an output mat, where the output mat contains less liquid than the pre-processed mat. The control system controls the pre-processing rate based on at least one characteristic of the output mat to maintain the at least one characteristic of the output mat within a predetermined range.

摘要： The present technology relates generally to fluid filtration systems. In particular, several embodiments are directed toward compartmentally expandable rotating belt filters and associated systems and methods. In some embodiments, for example, a filtering system for contaminated fluid includes a first fluid filtering chamber having a first filter belt movably positioned therein and a second fluid filtering chamber having a second filter belt movably positioned therein. The first filter belt can be operable in parallel with the second filter belt. The system can further include a sensor configured to sense a condition related a volume of the contaminated fluid, a speed of flow of the contaminated fluid, or a level of contaminants in the contaminated fluid. A controller can be configured to initiate, stop, or adjust fluid flow to the first fluid filtering chamber and second fluid filtering chamber individually in response to the sensed condition.

摘要： A method and device for drainage of a fibrous suspension where a converging drainage gap is formed between a first area and a second area. At least one of the first area or the second area is water permeable. A curved drainage zone is connected to the converging drainage gap. The first area moves relative to the second area. A fibrous suspension is introduced into the converging drainage gap. The fibrous suspension is transported by one of the first area and the second area as a layer. The first area and the second area are compressed closer together thereby causing drainage from the fibrous suspension through one of the first area or the second area.

摘要： A pulp-filter arrangement (1) comprises a rotatable drum (10) and a non-rotating valve arrangement (30). The rotatable drum (10) has a cylindrical water-permeable pulp-supporting shell (14), a plurality of drain pipes (16) and a rotating hollow shaft (18). The plurality of drainpipes (16) connects the rotating hollow shaft (18) with a collecting channel (22) situated radially directly inside the cylindrical water-permeable pulp-supporting shell (14). The non-rotating valve arrangement (30) is disposed within the rotating hollow shaft (18) for sealing off the rotating hollow shaft (18) from a radially inner outlet (24) of the drain pipes (16) when respective radially inner outlet (24) is situated within a sealed zone. The non-rotating valve arrangement (30) is further arranged to, in a transition zone immediately following the sealed zone, open a throttled passage between the rotating hollow shaft (18) and the radially inner outlet (24).

摘要： 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.
