Definitions

  • the invention relates to a separating device for separating contaminants from fluid to be cleaned, having at least one separating body with at least one collection area in which contaminants can collect, and with at least one load determination device, with which a contamination load state of at least part of at least one collection area can be determined.
  • the invention also relates to a load determination device for a separating device for separating contaminants from fluid to be cleaned, with which a contaminant load state of at least part of at least one collection area of at least one separating body of the separating device, in which contaminants can collect, can be determined.
  • the invention relates to a method for determining a contamination load state of at least part of at least one collecting area of at least one separating body of at least one separating device for separating contamination from a fluid to be cleaned.
  • an indicator device for providing information, in particular for outputting a signal, about the contamination load status of a separating device, in particular a fluid centrifuge, for separating contaminants, in particular particles, from a fluid, in particular oil, in particular an internal combustion engine, in particular a motor vehicle Separator and rotor of a fluid centrifuge known.
  • the indicator device has at least one in its shape and / or its position at least partially variable working part, which is at least partially in a collection area of the separating device, in particular a rotor of Fluid centrifuge, for separated contamination is or can be arranged so that it can be at least partially covered by separated contaminants depending on the contaminant loading condition.
  • the invention is based on the object of designing a separating device, a load determination device and a method of the type mentioned at the outset, in which a contamination load state of the at least one separating body can be determined more reliably.
  • the at least one load determination device has at least one transmitter for electromagnetic waves and at least one receiver for electromagnetic waves emitted by the at least one transmitter, the at least one transmitter and the at least one receiver being on opposite sides sides of at least one collection area for separated impurities of the at least one separating body, the at least one separating body being at least partially permeable at least in sections to the electromagnetic waves transmitted by the at least one transmitter, and the at least one transmitter and the at least one receiver are connected to at least one evaluation device, with which, from the electromagnetic waves received by the at least one receiver, the contamination load status of the at least one S collection area can be determined.
  • At least one transmitter and at least one receiver for electromagnetic waves are arranged on opposite sides of a collecting area for impurities. Electromagnetic waves are sent through the collection area with the at least one transmitter and received with the at least one receiver. In the collection area, the electromagnetic waves are attenuated depending on the amount of contamination deposited there, i.e. the contamination load status. The attenuation experienced by the electromagnetic waves as they pass through the collection area is therefore related to the contamination loading condition. From the attenuation of the received electromagnetic waves compared to the transmitted electromagnetic waves, the contamination loading state of the at least one collection area is determined.
  • the contaminant loading status of a collection area can characterize a degree of contaminant loading of the collection area.
  • the contamination load state can be given in the form of a degree of attenuation of the electromagnetic waves, as the thickness of a so-called cake formed from impurities, or in the form of some other type of quantitative and/or qualitative indication.
  • the contamination load status can be determined without contact. No mechanical connection is required between the load determination device and the at least one separating body. In this way, in the case of a moving separating body, in particular a rotor of a centrifugal separator, the movement of the separating body is not impaired by the determination of the load. In this way, the load can also be determined during ongoing operation of a separating device with a moving separating body.
  • Various materials can affect the signal distribution of electromagnetic waves.
  • the invention uses this damping property of different materials on electromagnetic waves.
  • an attenuation of electromagnetic waves as they pass through the collection area, in particular due to contamination with which the collection area is loaded, can be determined.
  • a correlation of the attenuation of the electromagnetic waves and the loading of the at least one collection area can be used to determine a maintenance interval for maintenance of the separating device.
  • a maintenance indicator can be implemented which displays the contamination loading status of the separating device. It can be indicated when the level of contamination has reached such a level that maintenance, in particular cleaning or replacement of the at least one separating body, is required. In this way, the operating time of the separating device can be extended overall. Further the quality of the fluid to be cleaned can be improved. In this way, devices, in particular engines, in which the cleaned fluid is used can be better protected.
  • the information about the contamination loading state is determined with at least one evaluation device.
  • the at least one evaluation device can advantageously be connected to a control device and/or an output device, which can be arranged remotely from the separating device, in particular in a control stand or a dashboard of a motor vehicle or the like.
  • the contamination loading status can thus also be monitored remotely from the separating device.
  • At least one evaluation device can advantageously be an electronic evaluation device.
  • the contamination loading state can be determined, in particular calculated, by software and/or hardware.
  • the at least one evaluation device can be connected to a corresponding electric/electronic control device of a machine, in particular a motor, in particular an internal combustion engine, and/or a vehicle. Appropriate information about the impurity loading status of the separating device can thus be transmitted to the control device and appropriate measures can be initiated.
  • the at least one evaluation device and/or at least one control device can be used to initiate the output of instructions, in particular acoustic and/or visual signals, or control functions for a machine.
  • the load determination device can advantageously be part of an oil centrifuge of an internal combustion engine.
  • the separating device in particular the oil centrifuge, can advantageously be part of an engine oil circuit of an internal combustion engine. It can be used to clean engine oil, which the Internal combustion engine is supplied.
  • the invention is not limited to a separating device of an engine oil circuit of an internal combustion engine. Rather, it can also be used in other types of separating devices and/or other types of liquid systems, in particular fuel systems or hydraulic systems, of vehicles, in particular motor vehicles, or other machines.
  • the separating device can be used in motor vehicle technology, in industrial engines or the like.
  • the separating device can be a separating device for separating impurities from liquid and/or gaseous fluid.
  • soot particles can be removed from engine oil with the separating device.
  • the at least one separating device can be a centrifugal separator which has at least one rotor which can be rotated about a rotor axis and which has a separating wall which surrounds the circumference of the rotor axis and on the radially inner circumferential side of which a collection area for separated impurities is implemented , wherein at least the separating wall is at least partially permeable at least in sections for the electromagnetic waves.
  • fluid to be cleaned can be brought into the interior of the at least one rotor.
  • impurities in the fluid to be cleaned in particular soot particles or the like, can be transported radially outwards due to the centrifugal force.
  • the impurities can be separated in the collection area on the radially inner peripheral side of the at least one rotor.
  • the load determination device works without contact. In this way, a contamination loading state can be determined during operation, ie when the rotor is rotating. It is not necessary to stop the separator while the contaminant load condition is being determined.
  • the at least one separating wall can be at least partially transparent to the electromagnetic waves, at least in sections. "Partially permeable" means that the at least one separating wall without electromagnetic waves Attenuation or with a this low attenuation passes. In this way, the electromagnetic waves can pass through the at least one separating wall. Thus, the electromagnetic waves can propagate with respect to the rotor axis from radially inside to radially outside or vice versa through the at least one separating wall and optionally the separated impurities. In this way, a contamination load state can be determined in connection with a thickness of the separated contaminants that is radial with respect to the rotor axis.
  • the separating wall can be at least partially made of non-metallic material, in particular a plastic composite material, GRP or the like.
  • the separating wall can be at least partially permeable to electromagnetic waves.
  • At least one transmitter can be arranged radially outside the circumferential separating wall with respect to the rotor axis and/or at least one receiver can be arranged radially outside the circumferential separating wall with respect to the rotor axis.
  • a space inside the separating wall can thus be used as a separating space for separating the impurity.
  • the at least one transmitter and/or the at least one receiver can be arranged outside the separating space loaded with impurities. In this way, contamination of the at least one transmitter and/or the at least one receiver by impurities can be avoided. Soiling of the transmitter and/or receiver can impair the function of the load determination device.
  • the at least one transmitter and/or the at least one receiver can be installed more easily outside the separating wall, in particular the rotor.
  • the at least one rotor can have a spindle which can be rotated about the rotor axis and on which the separating wall is rotatably held, and an imaginary connecting line between at least one transmitter and at least one receiver can run outside the spindle.
  • the spindle itself can thus be made of a material that is not or only slightly permeable to electromagnetic waves.
  • an imaginary connecting line between the at least one transmitter and the at least one receiver can run tangentially to an imaginary circular cylinder shell coaxial with the rotor axis.
  • the contamination loading state of the collection area can be determined at an axial height that is constant with respect to the rotor axis.
  • the centrifugal separator can have at least one speed determination device for determining the speed of the at least one rotor. By considering the speed, the contamination load condition can be more accurately determined.
  • At least one electronic evaluation device can be connected to the at least one rotational speed determination device and have means for determining a contamination load state from the received electromagnetic waves and the rotational speed of the rotor.
  • the contamination load status can be determined electronically from the rotational speed of the rotor and the electromagnetic waves received, or the attenuation of the electromagnetic waves received.
  • the electromagnetic waves can be radio waves.
  • Simple, inexpensive and reliable transmitters and receivers can be used to generate and receive radio waves.
  • Radio waves are known to be electromagnetic waves with a frequency below 3000 GHz.
  • the electromagnetic waves can be directed.
  • the electromagnetic waves can be directed towards the at least one collection area.
  • the monitoring of the impurity load state can be performed more efficiently.
  • the energy is spatially concentrated, particularly in the cross-section. The energy can be concentrated on the collection area. Energy losses in areas of no interest outside the collection area can be reduced will. Overall, a lower transmission energy can be used than with non-directional electromagnetic waves.
  • At least some of the electromagnetic waves can be continuous signals and/or at least some of the electromagnetic waves can be pulsed signals.
  • Continuous signals have the advantage that the contamination load status can be continuously monitored.
  • Pulse signals have the advantage that, given the same transmission power, the total transmission energy required can be reduced overall, since transmission pauses are inserted between the pulses. Alternatively, a correspondingly larger transmission power per signal pulse can be used without having to increase the total transmission energy as a result.
  • At least one transmitter and/or at least one receiver can be arranged on a housing inside of a housing of the separating device. In this way, the at least one transmitter and/or the at least one receiver can be fixedly mounted on the housing. The at least one transmitter and/or the at least one receiver do not have to be removed for maintenance of the separating device, in particular for cleaning and/or for replacing the at least one separating body.
  • the housing of the separating device can advantageously be openable. In this way, the at least one separating body can be made freely accessible for maintenance purposes.
  • the at least one transmitter and the at least one receiver can be arranged fixed to the housing and do not have to be moved with the at least one separating body.
  • At least one transmitter and/or at least one receiver can be encapsulated in a fluid-tight manner. In this way, the at least one transmitter and/or at least one receiver can be protected from fluid and/or contamination.
  • the at least one transmitter and/or the at least one receiver can advantageously be arranged in a fluid-tight encapsulated manner in a fluid-carrying area of the separating device, in particular within the housing.
