  • an oil filter cleaning system for cleaning a used oil filter with a cleaning fluid, said cleaning system comprising: means for forcing the cleaning fluid through the used oil filter under pressure in a reverse flow direction thereby dislodging debris trapped within the used oil filter in a discharge mixture; a particle sensor for detecting metallic particles in the discharge mixture; and means for straining the discharge mixture to remove and collect dislodged debris such that the strained discharge mixture is re-usable as the cleaning fluid.
  • an oil filter cleaning method for cleaning a used oil filter with a cleaning fluid comprising: forcing the cleaning fluid through the used oil filter in a reverse flow direction dislodging debris trapped in the used oil filter in a discharge mixture; detecting metallic particles in the discharge mixture; and straining the discharge mixture to remove and collect the debris therefrom such that the strained discharge mixture may be reused as cleaning fluid.
  • Fig. 1 is a schematic diagram illustrating an oil filter debris recovery and analysis system according to an embodiment of the present invention
  • Fig. 2 is a schematic diagrams illustrating a magnetic separator of the oil filter debris and recovery system illustrated in Fig. 1
  • Fig. 3 is a flow diagram of a method of removing debris from a used oil filter according to an embodiment of the present invention.
  • FIG. 1 shows an oil filter debris recovery and analysis system 50 according to an embodiment of the present invention.
  • the oil filter debris recovery and analysis system 50 cleans used oil filters 1 and recovers debris by pumping fluid, though one of the apertures where oil normally exits the filter and out the sides where oil normally enters the filter. That is, the fluid is pumped from the clean side to the dirty side of the used oil filter 1.
  • Fluid is pumped from a reservoir 6 to the used oil filter 1 , held in filter housing 2 at the top of the system 50, where the fluid is used to clean the used oil filter 1.
  • the pump 15, used for bringing the fluid from the reservoir 6 to the used oil filter 1 is located at the bottom of the system 50.
  • the outlet flow of the pump 15 can be controlled by a throttle valve or by a speed control device to accommodate washing different sizes of used oil filters 1.
  • An air supply fitting 16 is located at the side of the system 50 for allowing bursts of air to enter the system 50.
  • An air pressure regulator 17 located at the air inlet governs the supply pressure for the system 50.
  • the air pressure regulator 17 provides a compressed air supply to the system 50.
  • the air valve 18 regulates the introduction of timed compressed air pulses into the inlet pipe 4. These pressurized air pulses are introduced at regular intervals in order to assist in dislodging debris from the filter, allowing it to be washed away by the fluid.
  • the air pulses are introduced at timed intervals such that the used oil filter 1 is full of fluid and the burst of air helps speed the fluid through the filter 1.
  • the pump 15 and air valve 18 are electrically connected to the timing device 21 which is in turn connected to a power supply 22 via a switch.
  • Fluid pumped into the filter housing 2 via the inlet 4 passes through the used oil filter 1 and drains out through the bottom of the filter housing 2.
  • a vent 5, located at the side of the filter housing 2, is connected to a line leading down to the reservoir 6, which is at atmospheric pressure to prevent fluid mist from being sprayed out of the unit during the wash cycle.
  • a funnel 35 is attached to the bottom of the oil filter housing 2 to direct oil and debris toward a housing outlet 3. If the valve 29 is closed, then the housing vent 5 is sealed off and the compressed air flowing in through the filter 1 pressurizes the housing 2, forcing fluid through the outlet 3 at a higher flow rate. When the fluid level drops the float valve 29 opens, thereby venting the housing 2.
  • a magnetic separator 31 is located directly downstream of the filter housing 2. Fluid and debris that flow out of the filter housing 2 pass through an internal cavity 34 of the magnetic separator 31. The fluid and debris exit the magnetic separator 31 and enter a metal particle sensor 7 that detects and counts both ferromagnetic and non-ferromagnetic metal particles present in the fluid/debris mixture. The particle count data is output to a display at the front of the oil filter and debris recovery and analysis system 50. The display provides a visible indication of the number of metallic particles that have been detected.
  • the fluid passes from the metal particle sensor 7 into a fine mesh screen 9 in a screen housing 8 where debris from the used oil filter 1 is trapped.
  • the screen housing 8 consists of a funnel shaped container suspended inside a lid 12 of the reservoir 6.
  • the screen housing 8 is lined with a coarse wire mesh 11 to support the fine mesh screen 9.
  • An annular clamping mechanism 10 is located at the top edge of the screen housing 8 to secure the fine mesh screen 9 against the screen housing 8 during operation.
  • the fluid passes through the fine mesh screen 9 and the coarse wire mesh 11 and is sucked out of the screen housing 8 by the pump 15.
  • the cover 12 of the reservoir 6 is tray shaped with an outer lip and is perforated to allow fluid that overflows the screen housing 8 to drain into the reservoir 6.
  • the reservoir 6 itself has a funnel shaped bottom end.
  • the reservoir 6 is joined to the outlet at the bottom of the screen housing 8.
  • the pump 15 inlet is connected to a joining line 52 that joins the reservoir 6 and the outlet of the screen housing 8 such that fluid is pumped from the reservoir 6 and the screen housing 8 simultaneously.
  • a fine in-line filter 14 Directly downstream of the joining line 52 is a fine in-line filter 14 to filter out very fine debris that has been extracted from the used oil filter 1 and has not been trapped in the fine mesh screen 9. This ensures that the washing fluid remains clean as it is reused.
  • the debris extracted from the used oil filter 1 is contained in the fine mesh screen 9, which can be removed and replaced with a new screen element.
  • the used oil filter 1 is placed over an adapter fitting 23 that screws into the filter support 24.
  • the adapter fitting 23 creates a seal at the bottom end of the used oil filter 1.
  • a second adapter fitting 32 is attached to a turn screw 33 that is threaded through a housing lid 25. The purpose of the second adapter fitting 32 is to seal off the top aperture of the used oil filter 1. Pressure is applied by the turn screw 33 to ensure a tight seal at both ends of the filter 1.
  • Different top and bottom adapters 23, 32 could be used to accommodate different filter designs.
  • the filter housing lid 25 threads into the top of the housing 2.
  • a filter support 24 is suspended in the center of the filter housing 2 by four spokes, two of which are hollow.
  • the filter support 24 has four holes into which the spokes are inserted, one of which 26 extends up through the top meeting up with a threaded hole into which the adapter 23 is inserted.
  • One hollow spoke 26, extends into this hole and provides an inlet for fluid and air.
  • Another spoke 27 inserted in the filter support 24 connects to the vent line 5 and a vent hole 28 on the bottom surface of the filter support 24.
  • the tapered entrance of the vent hole 28 serves as a seat for the float valve 29.
  • Fig. 2 illustrates in detail the magnetic separator 31 shown in Fig. 1.
  • the magnetic separator 31 consists of an internal cavity 36 with the flow diffuser 34 that spreads the fluid and debris over a large flat area.
  • One of the flat walls of the cavity 36 is made of a thin non-magnetic material 37 against which a flat powerful magnet 38 is placed.
  • the magnet 38 can be turned on or off or be of the permanent type attached to a hinge 39 so that it can be placed against the flow cavity 36 to trap ferromagnetic particles and then pulled away to release them using an actuator 40.
  • the magnetic separator 31 traps and holds all ferromagnetic particles that pass through the cavity 36 until the wash cycle is complete and all non-ferromagnetic debris has been captured in the screen 9.
  • Fig.3 illustrates a method of removing and recovering debris from a used oil filter 60 according to an embodiment of the present invention.
  • a cleaning solution is forced through a used oil filter 62 in a reverse flow direction. This dislodges debris trapped within the used oil filter and creates a discharge mixture.
  • Air pulses at predetermined intervals are forced through the used oil filter 64 in a reverse flow direction. This speeds the flow of cleaning fluid through the used oil filter.
  • An enclosed housing covering the used oil filter is pressurized to increase flow of the discharge fluid that leaves the enclosed housing 66.
  • Ferromagnetic metallic particles are separated from the discharge mixture 68. This allows a count of both ferromagnetic metallic particles and non-ferromagnetic metallic particles to be performed when metallic particles are sensed in the discharge mixture 70.
  • the results of the particle count are output to a display 72.
  • the debris is then removed from the discharge mixture and collected by straining the discharge mixture 74.
  • the collected debris can be further analyzed 76 by other laboratory instruments external to the used
  • the cleaning fluid used in the oil filter debris and recovery system can be either oil or some solvent. Any used oil brought into the system will be mixed with the oil used to clean the filter. Oil is used because it is one of the least hazardous fluids that can be used to clean a filter and can be easily disposed of when it is too dirty to use.
  • the present invention as described above in the exemplary embodiments applies to the industrial field of cleaning used oil filters.

Abstract

Appareil pour nettoyer les filtres usagés, détecter les particules métalliques et collecter les débris de filtre. Le fluide et l'air sont chassés du filtre par pression, dans une direction contraire au sens de l'écoulement du filtre; ainsi les débris piégés dans le filtre à huile sont-ils évacués du filtre à huile. Ces débris s'écoulent à travers une sortie dans le boîtier du filtre à huile par gravité à travers un capteur de particules métalliques qui détecte et compte toutes les particules métalliques. Le fluide s'écoule ensuite dans un tamis à débris dans lequel toutes les particules dépassant une taille donnée sont retenues. Les débris solides sont retenus dans ce tamis, et le fluide passe à travers, en direction d'un réservoir. Une pompe assure la recirculation du fluide depuis le réservoir et depuis la grille.
