Abstract

An Axial Depth Filter device is a multipurpose process designed to separate water during the filtering process of oils and fuels as it removes contaminants and impurities.

Description

AXIAL DEPTH FILTER

This invention relates to improvements to filtering devices designed to extend the vivacity of all types of liquids such as Diesel and other motor fuels, motor oils, hydraulic fluids, paint thinners, specialty oils; such as essential oils and emulsions, organically grown oils et cetera by removing harmful substances from such liquids, including the removal of emulsified water commonly present in most oil based fluids.

The AXIAL DEPTH FILTER, puts forward an advanced method of filtering, removing a vast diversity from, to be filtered solutions. Despite its immense proficiency it is uniquely positioned environmentally. It is entirely self sufficient and does not rely on any type of propulsion or power and all of its component metal parts are recyclable.

Hereto employed, similarly aimed, filtering devices and/or methods do improve the quality of the here addressed liquids but do so at a much lower grade than the Axial Depth Filter by not totally eliminating these potentially damaging elements and substances; including emulsified water.

Motorized transport such as heavy duty trucks, busses, marine and earthmoving machines, for instance, usually rely on the filters supplied, and usually recommended, by manufacturer of the equipment. Although considered to be satisfactory, many of these filtering devices fail their purpose for various reasons. Chiefly because most fail to remove solid particles under 10 microns, which correspond to ca. 95% of contamination as well as the removal of moisture (free water) from oils, to acceptable levels.

Where heavy plant and machinery is required to work in extreme conditions i.e. long distance haulage and earthworks fine dust and other air-borne particles do enter otherwise sealed systems without being readily noticed. Suspended water, typically found in fuels is not removed entirely. Mining, marine, earthmoving and construction work, requires additional filtering devices. Some such secondary filters are commercially available, however, these are typically technically complex and therefore expensive with a question on their ability to perform as to their claim.

These problems are overcome with this invention.

The AXIAL DEPTH FILTER is a multi purpose filtering device that will remove water and other impurities, which adversely affect otherwise typical performance and life span of machinery, during normal filtering operation before contaminants are introduced or re-circulated in machinery and ancillary systems.

The AXIAL DEPTH FILTER is compact and the utilization of basic, relatively inexpensive components and, by employing a unique manufacturing method achieve unique function by design. The AXIAL DEPTH FILTER far exceeds the efficiency of presently available commercial devices, yet does this at very low initial price and at considerably reduced operating cost.

The AXIAL DEPTH FILTER can be manufactured for, and used on, any type of engine, motor or machine driven equipment that normally benefits from the use of oil and/or fuel filters by improving the varying functions of such equipment and, at the same time, increasing the overall operational efficiency.

Function and use.

The AXIAL DEPTH (Diesel OH / fuel) FILTER, in practical use, will separate and remove free water from fuel and eliminate other impurities and contaminants. The filter is capable of separating water from fuel at ca. 40 PPM. The removal of other particle contaminants is lower than 1 micron.

Fuel economy, power output and general engine efficiency is noticeably increased and exhaust emissions are substantially reduced extending fuel injector's life. Specific pressure and flow rates are dependant on the filter medium used in a particular filter but generally must not exceed 650KPA or equivalent to 18 liters of fuel flow per minute. Additional banking will be required if the pressure exceeds these limitations. All fittings are standard fittings. The period of useful operation of each filter is dependent on use and application such as fuel quality (water and contaminants). The typical life expectancy of a filter will be in the region of 30,000 liters.

The basic AXIAL DEPTH (oil) FILTER unit consists of a shaped 'cylindrical seamless metal primary module' which can be manufactured to any given size depending on its application and purpose. It features an outlet connection fitting at the bottom of the unit and an inlet connection fitting at the top of the unit.

AXIAL DEPTH (Hydraulic fluid) FILTER.

Used as a hydraulic oil filter, the AXIAL DEPTH FILTER works broadly in the same manner as that described for a fuel filter with the difference that it assists to keep fluid acid levels at acceptable levels. This promotes system longevity by reducing equipment wear.

The AXIAL DEPTH FILTER has its own pressure reduction system and can be fed from the most suitable pressure point of the hydraulic system. If the pressure is higher than 1000KPA a pressure reduction valve must be used but not lowered beyond 100KPA. unlike the fuel filter, the outlet is returned to the hydraulic fluid reservoir for recirculation. A typical filter change should take place after ca. every 500 hours of system operation. Manufactures oil analysis procedures must be adhere to and oil should be monitored and changed when indicated by such analysis.

The AXIAL DEPTH (fuel) FILTER unit consists of a shaped 'cylindrical seamless metal primary module' which can be manufactured to any given size depending on its application and purpose. It features an inlet connection fitting at the lower half side of the unit and an outlet connection fitting at the top of the unit. A reusable-bleeding valve is positioned at the lowest point of the filter .An inspection glass bowl is available. The AXIAL DEPTH FILTER and its variants are maintenance free and are not re-usable. When a filter has reached its maximum operational life it must be disposed of and a new filter installed, however, the savings in fuel, machine operational performance, reduced emissions and other benefits far outweigh the basic cost of a filter.

Basic Configuration and Components of the fuel filter

The actual AXIAL DEPTH (fuel) FILTER component is encased in a METAL HOUSING (Page C). This outer casing is formed from aluminum (metal spun) to precise specifications and can be made from other suitably strong material e.g. new generation industrial polymers. External service fittings are purpose positioned and vary dependent on the purpose to which a filter is put. The main fuel filter the INLET and locking disc (Page D fig. 10) and OUTLET (Page D fιg.3) are positioned differently to these of an oil filter. A PERFORATED LOCATION DISC (Page D fi .6) is positioned below the fuel outlet fitting (Page D fig. 3) and LOCKING RING (Fig. 1) encased in the SHAPING CONTROL DOME (Page D fig. 4) covering the top of the filter module.

The centre CORE (Page D fig.17) is held in the outer casing surrounded by the FILTER ELEMENT (Page D fig.8). The filter element and core assembly are seated firmly on the lower rim inside the outer casing shore up by a PERFORATED LOCATION DISC (Page D fig.6). and DISC SPACER (Page D fig.9) assembly. Below, and separated by the DISC SPACER is a specifically perforated WATER SEPARATOR DISC (Page D fig. 6a). The center core features CORE PLUGS (Page D fig.7) on both ends of the filter core to prevent fluid bypassing the filter. The WATER SEPARATOR ASSEMBLY (Page D fig.12) is positioned at the lowest point of the fuel filter casing ending with the Bleed VALVE (Fig. 13). Various smaller components such as O- rings, circlips and fittings complete the assembly. Although similar, OIL FILTERS (Page A fig. 2 & E) have fewer components are do not require the Water Separator (illuminator) feature. Basic Components of the Water Catchment Bowl The WATER CATCHMENT BOWL assembly fits onto the bleed valve fitting at the lowest part of the fuel filter (Page D fig 11). The BOWL ASSEMBLY (Page F) shows the Bowl Location Plate (fig. 1) with a seal and threaded spigot . The Transparent Glass Inspection Bowl (fig. 3) is held in place by the Location Stem (fig. 4). The Location Stem has a number of orifices which permits the collection and disposal of accumulated water when the Bleed Valve (fig.5) is opened.

Basic Configuration and Components of the oil filter The actual AXIAL DEPTH (oil) FILTER component is encased in a METAL HOUSING (Page E). This outer casing is also formed from aluminum (metal spun) to precise specifications and can be made from other suitably strong material e.g. new generation industrial polymers.

The main oil filter INLET FITTING (Page E fig. 3) and OUTLET FITTING and locking disc (Page E fig.9) are positioned differently to these of an fuel filter.

A PERFORATED LOCATION DISC (Page E fig.6) is positioned below the oil inlet fitting (Page E fig. 3) and LOCKING DISC (Page E fig. 1) encased in the

SHAPING CONTROL DOME (Page E fig. 4) covering the top of the filter module. The FILTER CORE (Page E fig.δa) is held in the outer casing surrounded by the FILTER ELEMENT (Page E fig.8). The filter element and core assembly are seated firmly on the lower rim inside the outer casing shored up by a PERFORATED LOCATION DISC (Page E fig.6). The center core features CORE PLUGS (Page E fig.7) on both ends of the filter core to prevent oil bypassing the filter. Various smaller components such as O-rings, circlips and fittings complete the assembly.

AXIAL DEPTH FILTER dimensions are dependent on filter demands and are relative to other mechanisms such as engine size, pressure, load and output. Diameters, height and weight will vary according to designs and fitting particular applications. Units from as small as a few centimeters across to large units with great capacity can be constructed.

Water, purged during the filtering cycle, can be drained periodically from the drain-cock, positioned at the bottom of the filter when deposited water is seen in the Catchment Bowl assembly (Page D fig.12 & Page F)

The AXIAL DEPTH FILTER can be manufactured to any specifications and any size depending on its final application. Materials used may vary depending on the final utilization and intention, i.e. AXIAL DEPTH FILTER used on land (Trucks and machinery) or at sea (boats and ships).

Installation.

The installation and use an AXIAL DEPTH FILTER is uncomplicated. The filter is designed to attach perpendicular, to any suitable flat, vertical surface. A specially designed filter clamp holder (Page A ) secures the filter firmly in an equipped position. These holding clamps or brackets are adapted to suit varying applications in case of vibration or difficulty in positioning.

Because of its compactness the AXIAL DEPTH FILTER can be fitted wherever sufficient, suitable space is available. After the filter is securely positioned, the various pipeline and pressure hose connection can be made.

The length of the 'hose or pipe-line' depends on the AXIAL DEPTH Filter's designed purpose (distance between engine, fuel-tank, reservoir etc. and filter). In essence all hose connections vary considerably and are dependant upon use and application. A filter used on a semi trailer will need different connections, and pipe lengths, to that of a tractor or a motor yacht / boat.

The AXIAL DEPTH FILTER module is commonly used as a secondary 'in-line' filter before the manufacturers primary filter. It can be installed on the pressure or vacuum side of the fuel supplies line. The AXIAL DEPTH FILTER are commonly fastened by the use of a filter strap assembly (Page A), or similar fastening method suitable for the intended application. If used on a truck, it may be positioned behind the driver's cab.

On machinery, tractors and the like, it may be best positioned where the operator can get best access to the unit.

When the AXIAL DEPTH FILTER has expired (satiated) and is exchanged with a new filter module the low point filter drain plug can be removed and reinstalled on the replacement AXIAL DEPTH FILTER.

Unique Manufacturing technique. Although the filter outer casing can be made from several different metals or other suitable materials the method described herein is that for aluminum metal spinning.

The outer casing (Pages A & G) is spun in the customary manner incorporating the pre-installed, necessary fittings (Page D). The walls extend beyond the height of the filter component inserts beyond the stepped section (Page H fig.1). After all Component items (Pages D & E) Are 'loaded' into the outer casing the Shaping Control Dome with fittings fitted (Page H fig.2) is firmly positioned onto the stepped section (Page H fig.3). The Shaping Control Dome becomes a permanently 'sealed-in-template' when the rest of the material is formed around the Shaping Control Dome into the final shape. By closely following the template shape, the fitting at the top of the filter is sealed permanently into the AXIAL DEPTH FILTER To assist with understanding this invention reference will now be made to the accompanying drawings which depict one typical example of the invention:
