A continuous disc filter device including a slurry containing bath, and a disc filter assembly comprising a rotor assembly supported to turn on a horizontal axis and having a filtrate outlet end, a plurality of filter discs spaced apart along the length of the rotor assembly horizontal axis, a plurality of spaced apart discharge conduits, and a plurality of disc filter section support and filtrate channel arms. Each disc filter section has a disc filter section filtrate outlet therein for filtrate to leave the disc filter section. A plurality of spaced apart discharge conduits each includes a discharge conduit housing extending along the rotor assembly horizontal axis and having a longitudinally extending discharge conduit filtrate passageway therein. Each discharge conduit is connected at one end to the rotor assembly filtrate outlet end and connected to respective disc filter section filtrate outlets, and each discharge conduit filtrate passageway is positioned between adjacent filter sections.

Continuous disc filter device

A disc segment adapted to be attached to other disc segments to form a disc assembly, the disc segment being in the form of a frame, the frame comprising a left side rail and a right side rail, and a plurality of spaced apart parallel horizontally extending ribs, each disc side including a corrugated wire mesh supported by the frame ribs, the corrugated wire mesh including crisscrossing wire strands, the strands crossing perpendicularly to each other, and the wire strands extend at an angle of 45 degrees relative to its frame rib.

Filter segment with a light weight frame

A disc segment adapted to be attached to other disc segments to form a disc assembly, the disc segment including an isosceles trapezoid frame. The frame comprises a left side rail and a right side rail, and a plurality of spaced apart parallel horizontally extending ribs connected between the side rails. The frame defines a first disc side and an opposite second disc side, each disc side including a corrugated left bottom clamp list adjacent the left side rail and supported by the ribs, and a corrugated right bottom clamp list adjacent the right side rail and supported by the ribs. Each disc side also includes a corrugated wire mesh supported by the left and right clamp lists, and supported by the frame ribs.

A disc filter sector comprising a trapezium tubular support frame, and a trapezium screen frame supporting a screen cloth, the trapezium filter medium element being connected to the trapezium tubular support structure. More particularly, there is a pair of such filter sectors, and the sectors are connected together by an overlying cap.

Disc filter and a method of constructing a disc filter sector

An assembly with hydrocyclones comprising: multiple hydrocyclones having a inlet chamber with two side openings positioned on opposite sides of the inlet chamber and a overflow chamber having two side openings positioned on opposite sides of the overflow chamber. The hydrocyclones are arranged at a support structure, comprising a support bar for support of the hydrocyclones. The hydrocyclones being arranged side by side with their side openings adjacent each other thus forming an inlet pipe by means of the inlet chambers and an overflow pipe by means of the overflow chambers. The inlet chambers and the overflow chambers are adapted to be pressed against each other respectively. The hydrocyclones being arranged in pairs with one of the two hydrocyclones arranged on one side of the support bar and the other on the opposite sides thereof. A method assembling multiple hydrocyclones, wherein hydrocyclones are hung on a support bar at a base end or a head portion and are pressed together, is provided, and a support structure for an assembly of hydrocyclones, comprising a support bar, an end bar and one or two underflow pipes.
