摘要:
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.

A belt filter apparatus for treating material to separate solid and liquid components comprises an endless belt structure adapted to circulate around a path incorporating guide roller structures around which the belt structure passes. The endless belt structure comprises an elongate belt portion of water permeable material, and has two opposed longitudinal edges. A zipper releasably connects the two longitudinal edges together to form a tubular structure with a flexible sidewall. The circulating path includes an assembly zone where the longitudinal edges are brought together and connected by the zipper to form the tubular structure, and a disassembly zone at which the zipper is released to separate the longitudinal edges and open the tubular structure. Means are provided for compressing a portion of the tubular structure to express liquid from the material contained in the tubular structure. The liquid discharges from the tubular structure through the water permeable belt portion.

The invention relates to an apparatus for continuous separation of dry matter from a fluid, comprising an enclosed environment capable of being under vacuum or under positive pressure, in which enclosed environment a number of rollers (1, 3, 4, 4′, 6, 6′, 20, 21, 22, 23) form a chamber which is divided into two or more compartments (12, 13, 24, 27, 25, 26) by filtration means (7, 8, 16, 29, 36, 37, 38, 40), wherein one or more filtrated chambers (9, 10) are placed on the pure side of the filter means. In order to allow for cleaning and/or maintenance of the filtrate chambers, additional filtrate chambers are provided, which are separated from the first filtrate chambers by a wall. One of the filtrate chambers at any time is placed under the filter, while the other filtrate chambers are situated outside the enclosure for maintenance/cleaning.

The invention is relative to a device for dehydrating sludge such as occurs in sewage treatment plants in the form of dilute sludge. The receptacle for the sludge contains a sieve surface comprising openings for the passage of liquid. The sieve surface, for its part, is substantially circular can be rotated about an axis (21) running vertically to the sieve surface. The axis (21) of the sieve surface (2) is inclined relative to a horizontal line and is caused to rotate by a drive device (3). The disk-shaped sieve surface (2) is arranged in a container (11) comprising a bottom (13) and a side wall (12) through which side wall a supply line (4) for the sludge and an outlet (41) for the separated water run.

The present invention concerns a method and an apparatus for separating dry matter from liquid, comprising providing an enclosed separation environment capable of being pressure regulated, and in said enclosed separation environment contacting at least one filter with a suspension accumulating dry matter on the at least one filter and passing the at least one filter through at least one set of rollers, whereby liquid is removed from the at least one filter, followed by removing the substantially dry filter cake from the at least one filter, wherein the above is performed in the same enclosed separation environment either under vacuum or overpressure. The invention further relates to obtaining a dry filter cake and the use of said filter cake, method and apparatus in, for example the food industry.
摘要:
A belt press having a frame with a first belt and a second belt rotatably mounted on the frame. A curved inlet guide is movably carried on the frame. The inlet guide has a decreasing radius of curvature from an inlet end to an exit end. A positioning assembly is mounted on the frame and is attached to the inlet end of the inlet guide to raise and lower the inlet end of the inlet guide.

Apparatus and process for separating components of a treatment mixture from a waste treatment system comprises feeding the treatment mixture to an endless filtering belt. The filtering belt has a mesh size selected to permit liquid components of the mixture to filter down through the belt while retaining particulate components thereon. The belt is moved by a drive system generally in a circuit between upstream and downstream ends of the apparatus as liquid components are separated from the mixture by filtering through the filtering belt. Unfiltered mixture is passed beneath a press disposed in opposed relation with the belt generally between the upstream and downstream ends of the apparatus. The press is capable of applying a squeezing pressure against the mixture to squeeze the mixture between the press and the filtering belt to separate water and liquified fatty components from the mixture for filtering through the belt. The press is adapted for movement toward and away from the filtering belt to allow the mixture to pass downstream of the press substantially without particulate components of the mixture being mashed into and entrained in the filtering belt by the squeezing pressure of the press.

A dehydration machine includes a stuff tank, a stuff inlet provided at a lower portion of the stuff tank, a stuff outlet provided at an upper portion of the stuff tank, and a pair of drums each having a circumferential wall with a plurality of water passage apertures, the pair of drums being juxtaposed in the stuff tank. The pair of drums rotate adversely about its respective axis so as to introduce stuffs in the stuff tank therebetween from a lower side thereof. One of the drum is rotatable in an immovable manner, and the other of the drums is rotatable in an inclinable manner while being urged toward the one of the drums by an air spring. Each of the drums is provided with a metal net on an outer surface of the circumferential wall.

Apparatus comprising at least one rotatably driven drum having a circumferential filter medium adjacent which pressurized liquid suspension containing fibrous material is supplied in the rotary direction of the drum driven rotation. One or more baffles, having low friction material on their surfaces opposing the filter medium, are resiliently biased by pressurized liquid and/or mechanical biasing means to gradually converge towards the filter medium in the rotary direction of the drum driven rotation, and fibrous material collected on the filter medium may be washed by either the biasing liquid or separately supplied pressurized liquid. Also, a method for processing a suspension containing fibrous material through the employment of such an apparatus.
