Abstract:
PURPOSE: A pressure swing adsorption(PSA) oxygen generator for direct current(DC) is provided to stably self-generate pure oxygen in a transporting unit and to prevent the occurrence of an oxygen supplying stopping phenomenon by detecting the insufficient supply of electricity capacity. CONSTITUTION: An air compressor(2) drives the driving electricity of an air compressing unit based on the using voltage of DC12V to DC30V at 40A or less of capacity. The voltage value of used DC electricity is recognized by a voltage sensor(16). A first pressure sensor(5) detects the change of pressure values in an air pressure line before compressed air is introduced into an oxygen separating adsorption column. A second pressure sensor(14) detects the pressure value when the high purity oxygen from the oxygen separating adsorption column is adjusted using a pressure adjuster. An alarming unit generates an alarm by comparing the detected voltage values with a programmed value.

Abstract:
There is disclosed a liquid filter system that includes a liquid filter apparatus configured to self-clean without removal of the filter apparatus from the filter system. The filter apparatus uses both a filter media for filtering solids as well as a spin motion imparted to fluid being filtered so that centrifugal force can remove solids from the liquid being filtered. The liquid filter system also includes a gas pulse nozzle in fluid communication with the liquid filter apparatus and is configured to flow gas into the filter media to expel water and debris trapped in the filter media without removing the filter media from the filter system.
Abstract:
Fluid processing apparatuses and systems are disclosed. In some embodiments the fluid processing apparatuses include a movable enclosure (38), a plurality of filter housings (30) disposed substantially within the movable enclosure (38), and a stand (36) disposed within the enclosure (38). The filter housings (46a; 47a; 48a) are in fluid communication with one another. Each filter housing (46a; 47a; 48a) defines an elongate path and is configured to support a respective filter (49) along the elongate flow path to filter a substantially continuous flow of fluid. The stand (36) supports each filter housing (46a; 47a; 48a) such that the elongate flow path of each filter housing (46a; 47a; 48a) is substantially parallel to a vertical axis, wherein each filter housing (46a; 47a; 48a) is independently rotatable, relative to the stand (36).
Abstract:
A system and method for dewatering a continuous stream of slurry at high flow rates demonstrates enhanced efficiency, economy and ease of operation. A stream of slurry is subject to continuous or continual measurement of flow rate and pulp density and the measurements are used to control the rate of addition of a flocculating agent to the slurry. The flocculated slurry is delivered to a dewatering unit (20) where it is passed through a diffuser (46) and evenly delivered to a tracking screen (44) for filtering solids from a liquid filtrate. The pulp density of the filtrate may also be measured and used to control addition of a flocculating agent. The tracking screen is adjusted to achieve an angle of repose suited to the particular composition of the filter cake. The diffuser has a base (126) having a horizontal section aspect ratio of from about 1:1 to about 4:1 and continuously changing vertically into an upper portion (130) having a horizontal section whith an aspect ratio of from about 40:1 to about 100:1. The ratio of the horizontal sectional areas at the upper portion with respect to the base is from about 1:1 to about 3:1. The dewatering unit (20) of the invention may be adjustable mounted on a transport means (40) for deployment of the high speed dewatering system and method at any convenient location.
Abstract:
The invention relates to a device for maintaining and cleaning a working medium (3), especially coolants, oils, grinding water, vehicle washing water and washing baths, which can be delivered to at least one filter by at least one line, especially a flexible tube (6). According to the invention, a vacuum and/or pressure-generating device is allocated to the filter (13) or to a filter pad (41, 41.1) and the filter can be approached from several sides. The working medium (3) enters the filter pad and passes from the inside of said filter pad (41, 41.1) to a transfer section (12).

Abstract:
A process delivery reservoir (10) and method is disclosed for continuously filtering particulate matter and oils from industrial fluids, such as coolants, oils, aqueous emulsions, etc., which are necessary in the operation of machine tools. The reservoir (10) utilizes a primary containment area (24) with a primary chip screen (18) and a first baffle (26) to trap much of the particulate matter and to contain tramp oil. The reservoir (10) also contains secondary and tertiary containment areas (28, 34) which utilize upper and lower baffles (32, 30) to further trap particulate matter and tramp oils, when said reservoir (10) is utilized with an aqueous emulsion. The industrial fluid remaining in the tertiary containment area (34) is ready to be delivered to the machine tool for reuse.
Abstract:
A device for dewatering sludge comprises a plurality of screening means (11) that are located at different levels, said screening means comprising hole-provided tube pieces which communicate with a common manifold (12) and through which water may pass in a direction from the outside and inwards, without the solid constituents of the sludge being carried along by the water. When necessary, the screening means may be back-flushed in order to keep them clean, shut-off valves (24) acting between the differently high situated screening means with the purpose of individually interrupting the communication between the manifold (12) and the screening means (11) that land(s) up above the surface (9) of the slurry (8), according as its level sinks during a dewatering operation.
