Definitions

  • the present invention relates to a device for cleaning an air filter of a vehicle, a cooler device for a vehicle and a method for cleaning an air filter of a vehicle.
  • a device or cooler device presented here can be used, for example, in a rail vehicle for cleaning plant fibers from a cooler grille.
  • the fine-meshed grille With a high air throughput and at the same time a high proportion of light vegetable fibers in the cooling air, the fine-meshed grille can clog over the course of a day, which significantly reduces the amount of cooling air and cooling capacity. Under certain circumstances, reliable operation of the vehicle can then only be guaranteed through daily maintenance, ie cleaning the filter or grille.
  • a harvesting machine which has a drive motor with a cooling circuit.
  • the cooling circuit comprises a cooler, followed by a fan and a filter upstream.
  • a vacuum chamber is assigned to a segment of the screen on the upstream side. Sieve and vacuum chamber can be rotated relative to each other, so that a continuous and segmental cleaning of the sieve is possible by suction of contaminants attached to it.
  • the cooling circuit comprises a cooler, followed by a fan and a filter upstream.
  • the backwash tube is connected to the fan via an inlet funnel in order to use part of the air drawn in by the fan to backwash the screen through the backwash openings.
  • the backwash tube is arranged on a rotatably mounted shaft so that by rotating the backwash tube a permanent segment-wise backwashing of the sieve is possible.
  • two blades are connected in a rotationally fixed manner to the shaft, which are arranged downstream of the sieve in the suction air flow of the fan and thereby drive the shaft in rotation.
  • two cover blades are rotatably connected to the shaft, which are arranged upstream of the sieve and run after the backwash tube in order to prevent the backwashed impurities from being sucked in again immediately.
  • a construction vehicle with a motor is known, the cooler of which is associated with a cleaning device.
  • the cleaning device works with compressed air, which acts on the cooler via stationary or adjustable distributor strips arranged upstream of the cooler with outlet openings, in order to blow away any impurities attached thereto or away from the cooler to blow through the radiator.
  • the outlet openings can be designed in such a way that the compressed air exits perpendicularly or at an angle to the plane of the cooler.
  • the air inlet grate is arranged horizontally, that is, lying, while the cooler is arranged vertically, that is, standing.
  • a blowing device is assigned to the air inlet grate, which works with compressed air and is arranged on the upstream side.
  • the air inlet grate has a corrugated structure and the blower device has an air supply bar which is arranged on an edge of the air inlet grate running transversely to the longitudinal direction of the corrugations of the corrugated structure so that the compressed air flows through nozzles into the valleys of the corrugated structure parallel to the longitudinal direction of the corrugations.
  • the blowing device is always activated when a reverse gear is engaged, since then a fan that intakes the cooling air inevitably has a reduced speed, at least temporarily.
  • the cleaning device for a cooler of an internal combustion engine, which acts on the cooler on the outflow side with a backwashing flow of compressed air.
  • the cleaning device comprises a stationary or adjustable, rust-like or lattice-like tubular structure with outlet openings for the compressed air.
  • the approach according to the invention is based on the knowledge that if compressed air is used to clean the air filter, a maintenance interval can be extended to several days until the radiator is next cleaned, even at times with a high proportion of fibers in the cooling air.
  • a device according to the approach presented here can be operated with energy sources present on the vehicle and can be constructed simply and robustly, so that it does not itself have to be the subject of intensive maintenance work.
  • the approach according to the invention offers the advantage that compressed air is already available, since it is used in almost all rail vehicles in the braking system. It can be controlled via low-maintenance solenoid valves.
  • the streamlined shape and the preferably small diameter of the tubes allow a small overall depth, since the cooling air flow is only slightly obstructed. Furthermore, excessive contamination cannot lead to clogging, damage or other failure of the devices according to the invention. These can be manufactured cost-effectively even with small quantities and can also be retrofitted to existing vehicles.
  • the approach according to the invention takes into account the problem that modern electric and diesel-powered multiple units are characterized by increasing performance and a high air requirement for cooling the drive components, while at the same time there is a desire by the operator of the multiple units for the longest possible maintenance intervals.
  • the approach presented here can help to ensure that these two issues no longer regularly lead to a conflict of objectives, e.g. when in summer the cooling air in some areas has a high proportion of light plant fibers such as poplar, dandelion, etc.
  • underfloor cooling systems which are arranged under the car floor, the fibers are deposited at the radiator inlet and can significantly hinder the air throughput through the radiator.
  • the required cooling capacity can be restored without having to manually vacuum the fiber residues on the air inlet side of the cooler up to once a day depending on the weather and application.
  • the approach presented here corresponds to the requirements of economical operation of the vehicles, which provide minimum intervals for the maintenance of several days.
  • the invention is based on the general idea of coupling the air filter to a vibrating device which vibrates the air filter for cleaning.
  • the impurities attached to the air filter can be loosened by a correspondingly higher-frequency vibration, so that they can fall due to gravity.
  • the air filter can expediently be held on a corresponding frame with vibration-capable fastening points.
  • elastomer bearings are suitable for attaching the air filter to the frame.
  • the air filter lies in an air filter plane, whose normal direction is inclined with respect to the main direction of the cooling air flow, for example in an angular range from 15 ° to 60 °, preferably from 15 ° to 30 °.
  • a solution in which the air filter is cleaned by means of the above-described compressed air backwashing in conjunction with the vibration described above is particularly advantageous.
  • the present invention thus provides, in particular, a device for cleaning an air filter of a vehicle, having the following features: a backwashing device comprising a pipe device with a connection for supplying compressed air and a plurality of nozzles for ejecting the compressed air in the direction of the air filter in order to clean the air filter , and a vibration device for vibrating the air filter to clean the air filter.
  • a backwashing device comprising a pipe device with a connection for supplying compressed air and a plurality of nozzles for ejecting the compressed air in the direction of the air filter in order to clean the air filter
  • a vibration device for vibrating the air filter to clean the air filter.
  • the respective device for cleaning can be arranged, for example, on a multiple unit of a rail vehicle or on a wagon of a rail vehicle.
  • the device can be used to cool a drive of the rail vehicle and, alternatively or in addition, to cool the interior of the rail vehicle.
  • the compressed air can be applied through the nozzles to a side of the air filter facing the nozzles, so that, for example, plant fibers on the side facing away from the nozzles can be lifted off and fall to the ground.
  • the air filter can be supplied with outside air, for example, by airflow.
  • the air filter can be a fine-meshed fleece or grid that is suitable, for example, to filter out fibrous materials of different sizes from the outside air.
  • the device can be arranged behind the air filter in the flow direction of the air flow to be cleaned by the air filter.
  • the compressed air escaping from the nozzles can thus flow in the direction of flow the opposite of the air flow.
  • the pipe device can have, for example, one or more interconnected round pipes through which the compressed air can flow.
  • the nozzles can be formed by openings in the pipe device, so that the compressed air flowing through the pipe device can be released through the nozzles in order to act on the air filter.
  • the connection for supplying the compressed air to the pipe device can be arranged in the one round pipe or one of the plurality of round pipes.
  • the connection can be, for example, a valve, in particular a pulse valve, via which the time and the duration of the drainage process can be controlled.
  • the connection can be connected directly or indirectly via a further connection to a compressed air line of the vehicle.
  • the device can have a frame element with a compressed air connection for connecting the frame element to a compressed air line.
  • the frame element can be designed to receive the pipe device in such a way that the compressed air connection can be connected to the connection of the pipe device.
  • the frame element can e.g. are a stable rectangular construction that is designed to accommodate the frame element and the air filter.
  • the frame element can advantageously be designed as a sealing frame which can accommodate the air filter in such a way that no plant fibers can penetrate past the edges of the air filter into the device and the interior of the vehicle and, for example, can impair the function of the radiator.
  • the tube device can have a plurality of tubes arranged adjacent to one another and two distributor tubes for receiving opposite ends of the plurality of tubes.
  • the plurality of tubes can have the plurality of nozzles.
  • the tubes can be arranged parallel to one another.
  • the nozzles can be evenly distributed over an entire length of the pipes.
  • the distribution pipes can have a larger diameter than the pipes, so that the compressed air can be distributed easily and quickly to the pipes.
  • Such a configuration of the pipe device has the advantage that the compressed air can be applied uniformly and over the entire area to the air filter and this can be cleaned uniformly.
  • the plurality of nozzles can each be arranged on a side of the plurality of pipes facing the air filter.
  • the nozzles are thus directed against the air flow coming from the outside, so that an efficiency of cleaning by means of compressed air is optimal.
  • a nozzle jet direction of the nozzles with which the nozzles emit the compressed air in the direction of the air filter is inclined with respect to a normal direction of a plane in which the air filter extends, e.g. in an angular range from 15 ° to 75 °. If the nozzle direction is not arranged at right angles to the filter grille, compressed air can be applied to a large area with just a few nozzles. Due to the angle of the nozzles, a greater distance from the filter grille can be achieved, the conical air jet generated then covering a substantially larger area than in the case of a right-angled arrangement.
  • At least one of the nozzles can be designed in such a way that it generates a nozzle jet rotating about a main emission direction. This can be achieved by rotating the respective nozzle itself or by arranging a rotating element in the stationary nozzle which generates the rotating nozzle jet. It is also possible to move a tube which has a plurality of nozzles in a circle, so that the individual nozzles each revolve around their main emission direction. The rotation can be generated by the connected compressed air or a separate additional drive. Such a rotation of the nozzles or of the jet stream can further improve the cleaning process, since with fewer nozzles a larger area can be acted upon with a high impulse and the dirt can be loosened more easily from the filter grille.
  • the cleaning performance is very good.
  • the number of nozzles can be kept very low, which has a positive effect on air pressure and air consumption.
  • the compressed air supply to the pipe device can be controlled with the aid of a pulse valve, such that the backwashing takes place with the aid of pulse-like backwashing pulses.
  • Short, impulsive compressed air blasts have a particularly high cleaning effect with a comparatively low air consumption. It is clear that multiple pressure surges can also be generated to intensify cleaning.
  • the air filter can be designed as a grid.
  • the grid can be designed as a fine-mesh stainless steel grid.
  • the use of a grating has the advantage that, due to its smooth surface properties, it can be cleaned of fibers well by means of air conveyed at high pressure.
  • a metal grille has the advantage of a long service life and is also dimensionally stable even with high air pressure.
  • the filter grille can be inclined, with the result that the dirt particles may already fall off the grating due to the force of gravity. At least it supports cleaning.
  • the air filter can be designed as a cooler.
  • an additional air filter can be used to increase the filter effect.
  • an additional air filter can be dispensed with, so that fewer components are required for the device presented here, as a result of which a maintenance effort can advantageously be reduced.
  • the present invention further provides a radiator device for a vehicle, having the following features: a device for cleaning according to one of the preceding claims; the air filter for filtering the cooling air; and a cooler for cooling the cooling air, the device, the air filter and the cooler being arranged adjacent to one another in a flow direction of the cooling air such that the air filter and / or the cooler can be cleaned by the device.
  • the cooler device can be used, for example, to cool a drive of a railcar of a rail vehicle.
  • the cooling air can be outside air that can flow through the air filter into the cooler device when the rail vehicle is moved.
  • the cooler can be designed so that the cooling air can flow through it.
  • the device can be arranged in the flow direction of the cooling air in a second position behind the air filter or alternatively in a second position behind the cooler or alternatively in a third position behind the air filter and the cooler.
  • the cooler device can have a fan for conveying the cooling air in the flow direction.
  • the fan can be a fan, which can be arranged in the last position in the cooling device in the flow direction of the cooling air.
  • the use of the fan in the cooler device has the advantage that the cooling air can reach the cooler faster and in larger quantities.
  • the device can be arranged in the flow direction of the cooling air in front of the cooler.
  • Such an arrangement of the device offers the advantage that the cooling air striking the cooler is already filtered.
  • An alternative arrangement of the device in the flow direction of the cooling air after the cooler can make the use of the air filter superfluous if the cooler is also used as an air filter.
  • the cooler can be cleaned by the device. If an air filter is arranged in front of the cooler, as seen in the direction of flow, the air filter can be cleaned by the compressed air of the device which flows through the cooler.
  • the more suitable of the two designs of the cooler device presented can be used.
  • the cooler device presented here can be part of an underfloor cooling system of a rail vehicle. Underfloor cooling systems of this type are frequently used to cool propellant drives. Due to the proximity of such systems to the ground and the associated high degree of contamination of the filter component, the approach presented here of efficient and economical filter cleaning is of particular importance.
  • the present invention furthermore provides a method for cleaning an air filter of a vehicle by means of a device for cleaning the air filter, which has a backwash device and / or a vibration device, the method comprising the following steps: detecting a state of motion of the vehicle and / or an operating state of a vehicle Fans for generating and / or supporting a cooling air flow; Actuating the backwashing device and / or the vibration device depending on the state of movement and / or operating state in order to clean the air filter by means of compressed air and / or by means of vibration.
  • the state of motion can relate to an acceleration or a speed of the vehicle.
  • the compressed air and / or vibration can be applied to the device at the end of an acceleration process.
  • the end of the acceleration process can be provided, for example, by means of a corresponding signal to a control device of the cleaning device.
  • the control unit can e.g. control a vibration generator and / or a valve of the connection in order to supply compressed air from a compressed air line of the vehicle to the pipe device.
  • the cleaning can be triggered, for example, when the vehicle is outside a town.
  • the operating status of the respective fan can be taken into account.
  • the respective fan generates or intensifies the cooling air flow, which creates the accumulation of contaminants on the air filter. If there is little or no cooling requirement, the fan can be switched off or only generate a comparatively weak cooling air flow. As a result, the cleaning effect can be improved if the cleaning takes place in operating phases in which the fan is not operating or is operating only with reduced power.
  • a corresponding control can monitor the power consumption of the fan or a signal correlated therewith in order to carry out the cleaning of the air filter preferably when the power of the fan is below a predetermined limit value.
