Abstract:
A spray ring is cycled back and forth along the longitudinal axis of a finisher to allow a high pressure cleaning stream of water or solvent to be directed against the surface of the finisher. A linear rodless cylinder is attached to the spray ring and is sequenced to move the spray ring, responsive to, among other possible inputs, flow measured by a flow switch or flow sensor as a control input to the device.
Abstract:
An improved method for separating solid particles from liquids, such as dewatering and thickening of sludge collected in a container (1), involves the use of at least one drainage unit (9) having doubled screened jacket walls (25, 26) defining a dewatering chamber (10). The liquid relieved of solids within the chamber is subjected to a turbulent motion acting against said screened jacket walls for obstruction of the solids deposition at the wall surfaces of the chamber facing the sludge in the container. The turbulent motion is obtained by a forced fluid F introduced in the chamber through one or more tubes (30, 31). The fluid may favorably be in form of compressed air or water returned from the reject system (14, 16).
Abstract:
A disk-type filter comprising a housing having an inlet connectable to an upstream pipe and an outlet connectable to a downstream pipe and a stack of filter units disposed within the housing for separating solid particles from a fluid flowing between filter units in the stack of filter units from an upstream side of the stack of filter units to a downstream side thereof, characterized in that the stack of filter units includes a plurality of co-operating filter units defining a plurality of paired co-operating filter surfaces, including first and second surfaces each defining a plurality of fingers, the fingers defined by the first surface being arranged in registration with the fingers defined by the second surface, the exteriors of the fingers defined by the first and second surfaces communicating with either one of an upstream side and a downstream side and the interiors of the fingers communicating with the other one of the upstream side or downstream side, spaces being defined in association with the fingers defined by the first and second surfaces and being disposed in registration so as to define channels, which permit particulate matter to become disengaged with the upstream side of the fingers defined by the first and second surfaces, the fingers of each disk being joined.
Abstract:
In a system for separating solids from a liquid in a slurry, a filter apparatus is cleaned by a jet and a removal device. The filter is generally flat and has an inflow side on which the solids are deposited and an outflow side supported by a grid. The grid subdivides the outflow side into a plurality of separate injection chambers and defines a plurality of separate small regions of the filter. The jet directs a stream of liquid through one of the injection chambers and against one of the small regions of the filter defined by the injection chamber. A cover plate is provided on the jet for engaging the grid to close one injection chamber opposite the filter. The removal device is located on the inflow side of the filter and is aligned with the jet to receive solids dislodged from the filter. The jet and removal device move simultaneously and in alignment to close selectively and to direct a stream of liquid through each of the injection chambers.
Abstract:
The sifting device consists of a chamber with an opening for feeding pulp to be sifted; a cylinder plate installed in the chamber so that it can be rotated around its axis; at least one fixed sieve cleaner with an outlet pipe open toward the sieve surface for removing reject pulp, a lower pressure prevailing in the outlet pipe than on the sieve surface; a detachment organ for reject installed in connection with the outlet pipe; and a blocking piece on the side opposite to the open part of the outlet pipe.
Abstract:
The present invention relates to a laundry machine, comprising: a tub (120) for receiving wash water; a drum (130) rotatably provided in the tub (120); an air supply device (160) provided at an upper part of the tub (120) for heating air discharged from the tub (120) and introducing the heated air into the tub (120); and a cooling water supply device (300) to supply cooling water to a rear inner surface of the tub (120) such that the rear inner surface of the tub (120) forms a condensing surface to generate condensed water.
Abstract:
A screen intake apparatus for a water intake system uses a cleaning system to clean one or more screen intakes. To clean debris from a screen, pipes in the interior of the screen receive pumped liquid ( e.g ., water or incompressible liquid) from a pump. Outlets, such as apertures or nozzles, on the pipes then direct the pumped liquid into the interior of the screen. One or more valves can vary, agitate, or pulse the flow of pumped fluid and/or can selectively deliver the pumped liquid to the pipes to remove collected debris from the exterior of the screen. A heater of the system can also heat the pumped liquid for delivery to the pipes to remove or prevent ice formation on the screen.
Abstract:
A system (1) for static filtration of liquids, having a tank (10) with at least one closed circular structure (20) therein, whose bottom is closed by a base (20a), the base (20a) being supported in a raised position with respect to the base (10a) of the tank (10); said structure (20) containing a series of concentric circular filter panels, each having two walls formed of filter cloths in spaced relationship to form filtering chambers (3) and (4) through which the filtered fluid flows out and chambers (5, 6, 7) for introduction of the liquid to be filtered.
