Definitions

  • the invention relates to a device for dust separation in the Roh Kunststoff Quarry an engine air intake of a vehicle, in particular a commercial vehicle, according to the preamble of claim 1. Furthermore, the invention relates to a method for actuating a device for dust separation in the raw air region of an engine air intake of a vehicle, in particular a commercial vehicle according to the preamble of claim 12 and a vehicle, in particular a commercial vehicle, according to claim 13.
  • the sucked for operating an internal combustion engine of a vehicle fresh air is usually cleaned with a dust filter.
  • a dust filter In particular, in commercial vehicles for a dust-intensive use complex devices are used as so-called Grobstaubvorabscheider.
  • Such a well-known coarse dust pre-separator as a multi-cyclone has at its input a plurality of swirl elements which set incoming fresh air into rotation. Due to the resulting centrifugal forces dust particles are deposited on surrounding walls. The separated dust particles fall down into a dust bin, which has a dust discharge valve on its underside.
  • the pre-cleaned engine fresh air is passed through dip tubes in a common intake and fed as pre-cleaned, dedusted fresh engine air via the dust or main filter of the engine.
  • the fresh air sucked in by the dust pre-separator can also contain water in addition to the dust, which is separated together with the dust. This can lead to sticking of the separated water-dust mixture, whereby the dust discharge valve is bonded and deactivated. This leads to a steady filling of the dust bunker and after reaching the full capacity, the degree of separation is reduced inadmissibly to zero.
  • the object of the invention is therefore to ensure the function of the device for dust separation in the raw air of the engine air intake with simple and inexpensive measures.
  • the dust discharge valve has an outlet opening and the operationally separated dust is at least partially collected in a dust collecting area in front of the outlet opening. Furthermore, the dust discharge valve has a closing element, which is arranged in the outlet direction openable at the outlet opening and keeps it closed during engine operation by a closing force.
  • the dust discharge valve is also controlled by means of an opening and / or free-blowing device and / or opened automatically and / or freely rotatable, so that no cumbersome manual operation of the Staubaustragsventils is required.
  • the dust discharge valve is preferably equipped with a controllable blow-out device directed towards the outlet opening as an opening and / or blow-out device, with the blow-off pressure of which the closure element can be opened and dust collected in the dust collection area can be blown out of the dust discharge valve at suitable time intervals.
  • the dust discharge valve is automatically opened and blown open at defined times and / or at defined time intervals.
  • the blow-off pressure, the blow-out time and the amount of air used must be adapted to the prevailing circumstances to ensure safe opening and blowing out of accumulated dust from the dust discharge valve even in critical conditions of high dust and water.
  • the blow-out device has an outlet nozzle, which is arranged in front of the outlet opening in front of the dust-collecting area and directed towards the latter.
  • the exhaust nozzle can be approximately centrally in a tubular valve body be arranged.
  • Such a blow-off nozzle is preferably connected to a blow-out or pneumatic line with a controllable, preferably pneumatic, pressure source.
  • pneumatic pressure sources as pressure accumulators are regularly present anyway in vehicles, and in particular in commercial vehicles, so that such a blow-off device can be realized simply and inexpensively.
  • such a blow-out or pneumatic line is connected via a control valve to the, for example pneumatic, pressure source of the vehicle.
  • a control valve can be actuated for a blow-out process for predetermined time cycles and / or given operating conditions and opened briefly.
  • the control valve can be opened for a short time once or several times a day or with ignition lock control for each start-up procedure for the blow-out function.
  • blow-off or pneumatic power is a vent line of a hand brake control valve, which blows off each time you insert a pneumatic parking brake air.
  • the above Staubaustragventil with the automated dust discharge function can be advantageously used in conjunction with known, built-in dust collectors, without that changes must be made there.
  • a dust discharge valve can still be seen vertically below the dust bin as seen in the vertical axis direction, in which case preferably the dust body connected to the bunker body region merges with a defined predetermined curvature in the discharge opening having dust collection area.
  • the tubular valve body can here run obliquely downward, in particular at an angle of approximately 120 °, towards the outlet opening. With such a sloping area, the dust accumulation for the blow-out function can be promoted there.
  • dust from the upstream dust bin can also fall behind during the blow-out process and be blown out with it.
  • closing element different, known per se elements, such as lips made of elastomeric material can be used.
  • a well-suited and simple closing element is proposed hingedly hinged at an edge of the outlet opening and openable in the outlet direction flap.
  • the closing force for this flap can be given, for example, by an operational negative pressure in the dust separation before the dust discharge valve.
  • a biasing force for example by a film hinge, can be applied to the flap for an airtight closure during engine operation.
  • such a closing force is to be set in conjunction with the dimensioning of the blow-out device that the closing force can be over-pushed by the blow-off pressure and the flap can be opened.
  • Fig. 1 a Grobstaubvorabscheider 1 is shown in a vertical section, as used in commercial vehicles for dust-intensive operations.
  • This coarse dust pre-separator 1 is equipped with an automatic dust discharge valve 2 according to the invention.
  • the coarse dust pre-separator 1 has at inlet openings 3 for the intake dust-laden fresh air (arrows 4) each swirl elements 5, which in the stacked intake pipes 6, the dust-displaced incoming fresh air in rotation offset (shown by arrows 7). Due to the centrifugal force thus generated, the dust particles contained in the fresh air 8 are deposited on the inner wall of the intake 6 and from there down into a dust bunker 9.
  • the pre-cleaned dedusted fresh engine air (arrows 10) passes through the rear with smaller outer diameter in the intake 6th inserted dip tubes 11 in a common fresh air duct 12, where a common pre-cleaned and dedusted engine fresh air flow (arrow 13) is sucked by the internal combustion engine.
  • the outlet opening 16 is here formed by a horizontally extending flat, firmly connected to the valve body 15 lip portion 19 and a folding axis 20 hinged (arrow 21) flap 22, wherein the flap 22 also has a flat front lip portion 23.
  • the two lip portions 19 and 23 are close to each other, wherein the closed state is kept operationally by a Ansaugunterdruck in Grobstaubvorabscheider 1.
  • the dust discharge valve 2 also centrally on a discharge nozzle 24 which is arranged centrally in the valve body 15 in front of the dust collection area 18 and the outlet opening 16 and directed with its nozzle opening to the outlet opening 16.
  • the exhaust nozzle 24 is connected to a pneumatic line 25 as a vent line to a (not shown) hand brake control valve of a pneumatic parking brake on each of the engagement of the parking brake briefly bleed air for venting and pressure reduction in the spring accumulator of the control valve.
  • a pneumatic line 25 as a vent line to a (not shown) hand brake control valve of a pneumatic parking brake on each of the engagement of the parking brake briefly bleed air for venting and pressure reduction in the spring accumulator of the control valve.
  • 3 and 4 connecting nipple 26 are shown for the pneumatic line 25.
  • the illustrated device for dust separation has the following function: each time the parking brake is engaged, a short burst of air is generated in the pneumatic line 25 and the discharge nozzle 24, through which the flap 22 is opened and dust is blown out of the dust collection area 18.
  • the so-designed blower works safely and easily without additional solenoid valves and controls.
