Abstract:
A filter bag assembly for a juice press is assembled from a unitary sheet of fabric and at least one coupling member and/or belt. The fabric sheet is foldable along a transverse fold line and then along left and right fold lines to form a seamless bag having left and right side margins each having four sheet layers. A left coupling member may be arranged to gather at least two of the four sheet layers of the left side margin, and a right coupling member may be arranged to gather at least two of the four sheet layers of the right side margin. Each belt connects the left side margin to the right side margin. Preformed holes in the fabric sheet are positioned to allow the coupling members and belt(s) to be installed to retain the folded bag. The assembled bag is inexpensive and the fabric sheet is replaceable.
Abstract:
A vertically elongate and orientated container (1) of wire cloth material contains a vertically orientated nozzle assembly (2), which against the inner wall of the container sprays a fibre suspension. The nozzle assembly is revolved around the axis of the container and is displaced backwards and forwards vertically so that the suspension sprays, which in the direction radially outward widen against the shell wall of the container (1) afford a cleaning effect in respect of deposited fibres on the inner wall of the container (1) at the same time as the liquid of the suspension efficiently is separated through the container wall in order to then be collected in a housing (9) surrounding the container (1). The device as well as the method are claimed (Fig. 1).
Abstract:
A filter assembly for a fuel delivery system for actuators and fuel control system of an aircraft engine includes a wash flow filter. Fuel flow velocity is increased through the filter through use of a recirculating passage that is effectively achieved through use of an ejector pump. A portion of the pressurized fuel delivered by the main fuel pump is diverted and serves as a motive fluid that scavenges unfiltered flow from downstream of the filter and recirculates or discharges the recirculated flow to an inlet of the filter. This provides increased velocity to maintain sufficient washing of the filter openings.
Abstract:
The invention concerns a device for filtering water of a swimming pool with at least one filtering bag characterized in that the inside of the filtering bag(s) (1) comprises arrangements for generating, under the effect of suction, a whirling movement by vortex effect, to suck up again and channel the particles in the suction axis of said bag, so as to delay or prevent particles or impurities from being deposited on said bag.
Abstract:
The invention relates to a device for thickening or dewatering sludge, watery sediments or the like, especially surplus sludge in sewage treatment plants. Said device is characterised in that it comprises a double-threaded or multi-threaded eccentric screw pump (10) having a shaft (14) on one end and a suction connection for fluid sludge (28) at the other end, a drive device which is coupled to the drive shaft (14, 18), and a transporting means which is arranged between the eccentric screw pump and the drive device, is driven by the drive device and is arranged in a longitudinal housing (16) through which the shaft (14) extends. A separating device in the form of a perforated cylinder (22) is arranged in said housing and is used to separate the sludge and the liquid. The inventive device also comprises a filtrate outlet (26) which is situated on the upstream side of the perforated cylinder, a thick sludge outlet (26a) which is situated on the downstream side of the perforated cylinder, and a supply device for a flocculent, said supply device being connected to the suction connection (28) of the eccentric screw pump and/or to the connecting region between the eccentric screw pump (10) and the perforated cylinder (22). The perforated cylinder (22) is rotatably positioned about its axis and can be rotatably driven by the drive device. The perforated cylinder comprises transporting elements on the inner wall, for transporting the sludge to the thick sludge outlet.
Abstract:
The invention relates to a device (1) for separating a substance into two phases, which device (1) comprises a screw conveyor (5) including a shaft and at least one screw (5) which is mounted on said shaft, which screw conveyor extends between an intake opening (9) for the substance and an outlet opening (16) for one of said two phases, as well as a cylindrical screen (10) provided with screen openings (11), within the screw conveyor (5) is rotatably disposed for conveying the substance in a direction of transport from said intake opening (9) to said outlet opening (16) via flow surfaces lying in a radial plane between said shaft, two successive screw threads in said radial plane and the screen, and for discharging the other one of said two phases via said screen openings (11), wherein the screw length of the screw conveyor (5) is determined by the length of the screen within which the screw extends, and wherein the flow surface area increases along the entire screw lenth, seen in the direction of transport.
Abstract:
A distillation system (10) is provided for recovering water from sea water and other polluted water source. The system (10) has a heat engine (12) embodying Carnot cycle and a Rankine cycle formed by heat exchangers (16 and 24), flash evaporator (26) and condenser (32). Burnt gases from the engine (12) such as a jet engine no longer fit for flying are directed into a duct (14) where the exchangers (16) and (24) are located. Sea water is pumped into the heat exchanger (24) for preheating by residue heat in the duct (14) and then into the exchanger (16) for further heating. A recirculating pump (20) raises water pressure in the exchanger (16) for increasing boiling point to about 165 DEG C. The heated water is fed into the evaporator (26) where it changes into vapour and the condensed into water by the condenser (32). The jet air stream is used to create Venturi effect for maintaining sub-atmospheric pressure in the evaporator (26). Any solid left in the evaporator (26) is removed by a transfer mechanism (50).
