Definitions

  • Modern electric traction vehicles require large amounts of cooling air to cool the electrical and electronic apparatus installed on the traction vehicle and to cool the traction motors.
  • This cooling air is drawn in via ventilation grilles or blinds using axial or radial fans. After flowing through the various coolers or traction motors, the heated air exits outside.
  • suction paths must be designed so that entrained dust, snow and rain are largely separated from the components to be cooled.
  • Previously used separators either require large suction areas (e.g. grilles with mat filters) and periodic maintenance or considerable installation volumes (e.g. acceleration filters) with the installation of additional flushing devices.
  • a centrifugal separator for separating dust, snow and water drops from the cooling air for an electrical machine consisting of a cylindrical housing, an air flow guide body and a collecting container for dust, snow and water drops, which is circular in cross section and attached to the cylindrical housing.
  • an axial counterflow fan consisting of two fans rotating against each other; an axial air flow guide body is provided on the air outlet side of the counterflow blower, which on the one hand has radially three-dimensionally curved guide vanes on the air outlet side of the counterflow fan, which are fastened in the cylindrical housing and deflect the air flow spirally around the air flow guide body and on the other hand has radially three-dimensionally oppositely curved guide vanes at its end, which are attached to the inside of the cylindrical collecting container, which is connected to the cylindrical housing and has an annular opening in the direction of the counterflow fan.
  • the collecting container is designed in the shape of a screw and has a nozzle-shaped outlet opening, the screw being designed to fall in the direction of this outlet opening. Apart from the rather complex design of such a combination, the noise generated by the axial fans used is considerable or disruptive at the necessary high speed.
  • GB-PS 821,574 The subject of GB-PS 821,574 is a dust separator. Dust-laden air arrives laterally from below or below into an antechamber, where it is set into an upward helical movement by fixed guide vanes, which is caused by a fan at the outlet of a separation chamber. All of the air supplied to the dust collector must be passed through an annular gap between the fan and the fins.
  • screens are installed in the wall of the separator housing, which guide part of the dust into a dust outlet.
  • the invention has for its object to provide a radial fan with integrated dust or dirt separator for electric traction vehicles, which is characterized by a small footprint, acceptable noise and high separation efficiency.
  • it should also offer the possibility of easily changing operating conditions, e.g. Winter use to be customizable.
  • the guide devices are preferably formed in one piece with the housing wall and are formed by wall parts bent out of the wall by a few angular degrees. In this way, they act as baffle plates, on which dirt can settle, but which is entrained in the outflow channel due to the high flow velocity.
  • the amount of purging air flowing through these channels can be adapted to the respective operating conditions, purging air amounts between 10 and 15% of the total amount of air conveyed by the radial fan proving to be expedient.
  • control devices can be configured as adjustable slats, e.g. be activated by a common adjustment and locking means, be formed, which e.g. is important for winter use where large amounts of flying snow have to be separated.
  • a radial fan wheel 3 driven by a motor 2 is arranged concentrically in a cylindrical air guide housing 1 and held by a motor mount 4.
  • the motor mount 4 is supported on the air duct housing 1 via radial webs 5.
  • the air duct housing 1 continues on the outflow side via a flange connection 6 in an outflow pipe 7.
  • the air conveyed by the centrifugal fan is fed from there to the individual machine and system parts to be cooled, such as air / oil coolers, traction motors, etc.
  • the inflow end of the air guide housing 1 is also connected via a flange connection 8 to an inflow pipe 9, which leads to the air inflow openings on the upper part of the locomotive box (see top side view in Figure 10, op. Cit.).
  • the wall of the air duct housing 1 is provided with guide devices.
  • these consist of lamellae 10 which are made in one piece with the wall and are bent outwards therefrom and which extend uniformly over the entire wall circumference.
  • a separating space 11 designed as an annular channel with a cross section widening in the direction of rotation of the fan surrounds the wall zone formed by the bent-out slats 10.
  • the separating space 11 is connected via a flange connection 12 to a pipe 13, which preferably leads to the underside of the locomotive box.
  • the amount of purge air can be increased by increasing the Aperture or adjustment of the slats 10 are enlarged. This is shown schematically in the development of the subject of the invention according to FIG. 3.
  • the connection between the outflow space 14 of the fan and the separating space 11 is made through openings 15 in the wall of the ventilation housing 1.
  • slats 16 serving as guide devices can be pivoted, e.g. attached via a self-locking hinge 17.
  • the opening angle of the slats 16 determines the amount of purge air through the openings 15.
