Definitions

  • the present invention pertains to a filter.
  • the invention is intended for an air filter, for example, but its application is not limited to that.
  • filters such as air filters and oil filters, are used in compressors, among other equipment, to clean the air or oil from any impurities.
  • Such filters encompass a housing with a replaceable filter cartridge.
  • the fluid that is to be cleaned passes through the filter cartridge.
  • the filter cartridge stops the impurities, and the cleaned fluid flows out.
  • the filter cartridge becomes saturated with impurities and needs to be replaced.
  • This replacement procedure entails opening the filter housing and removing the filter cartridge, after which a new filter cartridge is inserted.
  • Such data include, for example : the type of filter cartridge that is used, the usage time or time passed since the installation of the filter cartridge, and the total number of operating hours of the filter cartridge.
  • This data can be collected by the machine operator, but this method would be subject to errors and error margins. It is, therefore, preferable to collect this information automatically.
  • This invention aims at solving at least one of the aforementioned and other disadvantages, as it provides a filter that allows for the automatic collection of the data mentioned above.
  • the invention concerns a filter with a housing in which a filter cartridge can be provided, with the characteristic that the filter is provided with an RFID reader with an antenna, whereby this antenna forms a loop, at least once, around the filter cartridge installed in the housing, or around, or mostly around, a geometrical axial extension along of the filter cartridge.
  • a 'geometrical axial extension of the filter cartridge 7 refers to a fictitious extension of the filter cartridge in its axial direction.
  • the phrase 'around, or mostly around 7 is meant to imply that it is not impossible that the antenna, for a part of the circumference of the loop, overlaps with the geometric extension of the filter cartridge. For example, it is not impossible that the loop, for a limited segment of the circumference, will be indented in such a way that it will intersect with the geometric extension of the filter cartridge .
  • One advantage is that the use of the RFID reader with the antenna allows for the reading of a so-called RFID tag, which can be attached on or in the filter cartridge.
  • RFID tags can contain a variety of data, such as the type of filter cartridge. This can, for example, be a unique identification code that contains this information.
  • the RFID reader can read this information using the antenna. In this way, it is possible to determine which filter cartridge is installed in the filter.
  • the usage duration of the corresponding filter cartridge in the filter can be ascertained.
  • the actual number of operating hours of the filter cartridge in these specific circumstances can also be determined.
  • Another significant benefit is that, with the above- mentioned orientation of the antenna, whereby it is looped at least once around the filter cartridge or its geometric extension, it is always possible to have the antenna read the RFID tag, regardless of the position and orientation of the RFID tag on the filter cartridge.
  • the antenna is ideally placed on a plane perpendicular, or virtually perpendicular, to the symmetry axis of an installed filter cartridge.
  • the expression 'virtually perpendicular' means a maximum deviation of 15° from the perpendicular direction referred to, preferably a maximum deviation of 10°, or rather 5°, from the perpendicular direction. This will optimize the reception of the antenna.
  • FIG. 1 is a schematic representation, in perspective, of the filter in accordance with the invention.
  • Figure 2 shows the cross section of Figure 1 with the Plane 11-11;
  • FIG. 3 shows the section indicated as F3 in Figure 2 in more detail
  • Figure 4 shows a cross section of Figure 1 with the Plane IV-IV;
  • Figure 5 shows an alternative version of Figure 1.
  • the filter 1 represented schematically and in perspective of the in accordance with the invention in figure 1, concerns an air filter.
  • the invention is not limited to this application. It can, for example, also be applied to an oil filter.
  • the depicted filter 1 is typically used as an inlet filter for a compressor. Again, this is not the only application of the invention. It could also be used for an outlet filter or a filter for an expander, a vacuum pump, et cetera.
  • filter 1 mainly consists of a housing 2.
  • housing 2 contains a pot 3, that can be closed off with lid 4.
  • Lid 4 is equipped with air outlet 5, which is connected to the inlet of a compressor.
  • a sensor 6 is attached to housing 2 - to be specific, to lid
  • This sensor 6 can determine or measure one or more parameters of the fluid (in this example: air) that passes through filter 1.
  • sensor 6 has been equipped with one or more of the following elements:
  • sensor 6 may contain other elements to measure physical parameters.
  • a sensor like sensor 6 is also referred to as an 'Inlet
  • FIG. 1 shows a cross section of filter
  • This figure shows a filter cartridge 7 being provided inside the housing 2.
  • This filter cartridge 7 consists of filter medium 8 and is provided with an RFID tag 9.
  • This RFID tag 9 contains information about the filter cartridge 7, for example, its identification code.
  • the filter 1 is equipped with an RFID reader 10 and an antenna 11.
  • the antenna 11 forms a loop that runs around the filter cartridge 7 at least once.
  • the antenna 11 consists of one or more circular loops of a conductor, such as a cable or etched conductor paths on a circuit board.
  • the exact location of the antenna 11 does not limit the invention, as long as the antenna 11 extends around the filter cartridge 7 or a geometric axial extension of filter cartridge 7.
  • antenna 11 is positioned on a plane perpendicular or virtually perpendicular to symmetry axis 12 of filter cartridge 7.
  • the antenna 11 extends inside housing 2, where antenna 11 is attached to lid 4. It is attached to lid 4 using cover ring 13.
  • Figure 4 shows the bottom side of lid 4 and displays the position of antenna 11.
  • lid 4 It would also be possible to install antenna 11 between lid 4 and pot 3, for example on a flange of pot 3 on which lid 4 is mounted.
  • antenna 11 it is also possible for antenna 11 to be integrated into housing 2. If housing 2 were to be manufactured out of cast plastic, antenna 11 could be cast inside lid 4 or pot 3.
  • the electronic components would not be mounted to a traditional circuit board but glued on a plastic foil with printed conductor paths, which then would also be cast in the mold for lid 4 and/or pot 3.
  • An advantage of such an integration is that the total costs are lower than those of the sum of the separate parts, that is of lid 4 and/or pot 3 of filter housing 2, antenna 11 and sensor 6.
  • antenna 11 is mounted coaxially with filter cartridge 7.
  • RFID reader 10 contains antenna 11, as well as matching circuit 14. A suitable connector is used to connect RFID reader 10 to a computer or a similar device, to read the collected data from RFID reader 10.
  • RFID reader 10 will be connected to the above-mentioned sensor 6, but it is also possible that RFID reader 10 is part of sensor 6.
  • filter 1 The operation of filter 1 is very simple and as follows.
  • RFID reader 10 can read RFID tag 9 of filter cartridge 7 and identify filter cartridge 7.
  • RFID reader 10 When RFID reader 10 is connected to or makes up part of the above-mentioned sensor 6, this information from RFID reader 10 can be read and processed along with the data from sensor
  • Figure 5 shows a variant according to figure 1, whereby antenna 11 is placed around housing 2.
  • antenna 11 in figure 1 is placed inside housing 2
  • antenna 11 in figure 5 is placed outside of filter 1.
  • Antenna 11 is simply placed in the form of a ring around housing 2, more specifically, around air outlet 5 on lid 4, where the above-mentioned sensor 6 is also placed.
  • filter 1 Other elements of filter 1 are identical to the previously described version as represented in figures 1 to 4. Its functioning is also identical.
