Definitions

  • the invention relates to a device for separating particles from a fluid.
  • the device is suitable for removing even the smallest particles from air and is suitable for use in a vacuum cleaner.
  • Cyclones can be mentioned as an example of devices in which particles are separated from air without being deposited on a filter element. Cyclones have an essentially cylindrical housing that tapers in the lower area. The air laden with particles is supplied tangentially at a high speed in the upper area of the housing. With that Air-dust mixture flowing in at very high speed induces a vortex flow inside the cyclone, through which heavier dust particles are pressed against the housing wall and slowed down there. Due to gravity, they sink down into the funnel-shaped area of the housing. The separated particles are collected there and removed from the housing from time to time. Fine particles are difficult to separate with a cyclone because the centrifugal force acting on them is not large enough.
  • the fine particles are therefore dragged along by the exiting fluid through the exit pipe arranged in the upper region of the cyclone.
  • two cyclones are often connected in series. Even in this case, however, it is hardly possible to reliably separate particles with a particle size of less than 5 ⁇ m.
  • a dust cleaner which is based on the principle of a cyclone, is described, for example, in WO-A-98/10691.
  • a double cyclone is used to separate the dust from the air, in which a cyclone for separating small particles is arranged concentrically within a cyclone for separating coarse particles.
  • the double cyclone is relatively space-saving and is still suitable for use in a vacuum cleaner. Since no filter element is used in this vacuum cleaner, which is clogged by particles, the suction power of this vacuum cleaner remains practically constant over time. However, it is disadvantageous that the vacuum cleaner is still relatively large despite the use of the concentrically arranged cyclones.
  • the funnel-shaped collecting area for the separated particles In order to prevent the particles which have collected in the funnel-shaped region from being whirled up again by the vortex flow inside the housing and from reaching the outside through the air outlet, the funnel-shaped collecting area for the separated particles must be made relatively long. However, the entrainment of particles with the exhaust air cannot be completely avoided. Even the separation of very fine particles is not completely successful for the reasons described above. Therefore, downstream fleece filters must also be used, which are blocked by the deposited particles and must therefore be replaced from time to time.
  • the object of the invention is to provide a device for separating particles from a fluid, which has a constantly high separation effect even for very small particles with a particle size of up to less than 1 ⁇ m.
  • the device should also be built as small as possible and be maintenance-free over a long period of time.
  • the particles should be easy to remove and the device should be suitable for use in a vacuum cleaner.
  • the invention also relates to a vacuum cleaner which comprises the device according to the invention for separating particles from a fluid.
  • the invention thus relates to a device for separating particles from a fluid, the fluid being either gaseous or liquid.
  • the device according to the invention is particularly suitable for removing solid particles such as dust from air.
  • a filter element is arranged in a separation chamber with a side boundary and a base plate in an upper region located away from the base plate at a distance from the side boundary and the base plate.
  • the filter element serves to remove the particles from the fluid to be cleaned.
  • the fluid freed from the particles passes through the filter element to a fluid outlet opening located in the upper region of the separation chamber.
  • the device also has an inlet opening for the particle-laden fluid outside the filter element, which is inside the separation chamber by a fan, which on the side of the filter plate facing away from the base plate.
  • the inflow speed of the fluid can therefore be relatively low, since the fluid is conveyed in the separation chamber with the aid of the fan and is set into a rotational flow.
  • the device in addition to the separation chamber, which is also referred to below as the swirl chamber, the device has a collecting chamber for the particles separated in the separation chamber.
  • the separation chamber and the collecting chamber are connected to one another via at least one particle outlet opening.
  • the separation of the vortex chamber and the collecting chamber prevents particles which have been separated from being whirled up again by the vortex flow within the separation chamber, accumulating in large concentration in the separation chamber and finally passing through the filter element with the fluid and back through the fluid outlet opening into the Surrounding area.
  • the collecting chamber separated from the swirl chamber facilitates the emptying of the separated particles.
  • the vortex chamber with the actual separating device does not have to be opened when the separated particles are removed.
  • the base plate of the separation chamber is either flat or curved from the side boundary in the direction of the filter element.
  • the device according to the invention thus differs significantly from cyclone separating devices or comparable separating devices in which the bottom region of the housing runs downwards in a funnel shape. On the one hand, this has the advantage that the The inventive device can be made significantly smaller than was previously possible with cyclones.
  • the special design of the base plate has a favorable influence on the flow conditions within the swirl chamber in such a way that the separated particles are very quickly guided in the direction of the at least one particle outlet opening.
  • the special design of the device according to the invention means that the particles to be separated are quickly separated from the fluid and immediately get into the collecting chamber. The particles to be separated are therefore very quickly removed from the swirl chamber and cannot accumulate in it. The risk that particles which have been separated off are repeatedly whirled up, their concentration in the separation chamber increases greatly and ultimately particles with the fluid return to the environment is avoided.
  • the at least one particle outlet opening can be arranged, for example, in the region of the swirl chamber in which the side boundary and base plate adjoin one another.
  • the at least one particle outlet opening can be arranged, for example, in the region of the swirl chamber in which the side boundary and base plate adjoin one another.
  • the separation chamber itself can for example be essentially rotationally symmetrical. It is expedient that the swirl chamber has an essentially cylindrical outer contour. On the other hand, in some cases be favorable to give the separation chamber an asymmetrical cross section and to design it, for example, with an oval or helical cross section. In such a case, it is particularly preferred to arrange the at least one particle outlet opening as far as possible from the filter element. Due to the asymmetrical design of the separation chamber, the separated particles are accumulated due to the flow conditions in the separation chamber in the area of the chamber which is particularly far away from the filter element. They can therefore be fed to a particle outlet opening there in a particularly targeted manner.
  • the filter element which is used to separate the particles from the fluid, can, for example, have an essentially rotationally symmetrical outer peripheral surface. It is preferred if the filter element has the shape of a cylinder jacket.
  • the filter element can have the shape of an immersion tube.
  • the filter element is thus a cylinder tube which projects into the separation chamber from above and is at a distance from the base plate with its end which is open at the bottom.
  • the fluid loaded with particles in the vortex chamber is swirled by the fan in the chamber. Heavy particles are pressed outwards against the wall of the vortex chamber by the centrifugal force acting on them and sink to the bottom here. Lighter particles bounce off the outer wall of the cylinder tube and in this way also sink down towards the base plate. There the separated particles are moved by the vortex flow towards the particle driven openings and fall from there into the particle collection chamber.
  • the fluid freed from the particles enters the filter element through the lower open end of the tube, passes through this to the fluid outlet opening and leaves the separating device from there.
  • the filter element In order to achieve a uniform flow within the swirl chamber, it is expedient to arrange the filter element in the center of the separation chamber as far as possible.
  • the axis of rotation of the filter element and the central axis of the separation chamber therefore preferably coincide.
  • the rotationally symmetrical filter element need not have a constant diameter over its entire length. Rather, the diameter can change over the length of the filter element in order to specifically influence the flow in the swirl chamber. For example, it can be expedient to increase or to reduce the diameter of the filter element in the direction of the base plate.
  • the filter element has through openings in the area of its outer peripheral surface, while the end face facing the base plate is closed.
  • a multiplicity of parallel longitudinal bars can be arranged on the outer peripheral surface.
  • the filter elements are described in EP 0 748 645 A2.
  • the filter elements are used in a housing which corresponds to a cyclone housing and has a particle outlet tapering downwards in a funnel shape.
  • the filter elements are rotatably mounted. It is expedient to have the filter element and fan driven by the same drive device and to arrange all three components of the device according to the invention on one axis. In this way, the device according to the invention can be built in a particularly space-saving and economical manner.
  • the separation of particles and fluid is based on the fact that the particles that get into the area of the filter element either collide with it and are knocked away by it or get into the eddies generated by the rotating filter element and in this way from the filter element be pushed off.
  • the position of the collecting chamber for receiving the separated particles depends primarily on the planned application of the device according to the invention and on the position of the particle outlet opening (s) in the vortex chamber.
  • the separation chamber is arranged in the collecting chamber. This can be useful, for example, if there are a large number of particle outlet openings along the bottom plate of the separation chamber.
  • the separation of the vortex chamber and the collecting chamber has the advantage that once particles have entered the collecting chamber, they cannot be whirled up again by the flow in the separation chamber and carried away with the fluid through the fluid outlet opening.
  • Another advantage is that the separated particles can be removed from the separate collecting chamber much more easily than would be possible from the separation chamber. Damage to the separator during the removal of the particles is practically impossible.
  • Another advantage is that a collection bag for the particles can be attached in the collection chamber. This has the advantage that the operator of the device according to the invention does not come into contact with the loose dust. The particles can be disposed of together with the collection bag, which not only simplifies the disposal itself, but also significantly reduces the risk of allergies.
  • the collecting bags can be very simple and, for example, only consist of a thin paper or plastic bag. In terms of price, they are therefore considerably cheaper than conventional vacuum cleaner bags.
  • the collecting bag can have a self-closing opening in the region which is adjacent to the particle outlet opening of the separation chamber.
  • a movable flap for example, as is known from conventional vacuum cleaner bags, can serve as a closure.
  • the collecting chamber is expediently accessible from the outside of the device. The removal of the captured particles is particularly easy if the collecting chamber is provided with a removable drawer.
  • the described device according to the invention is extremely suitable for use in a vacuum cleaner.
  • Conventional house vacuum cleaners can be mentioned as examples.

Abstract

Dispositif permettant de séparer des particules d'un fluide, ainsi qu'aspirateur dans lequel ledit dispositif est utilisé. Ce dispositif (1) comporte une chambre de séparation (2) dotée d'un orifice d'entrée (9) et d'un orifice de sortie (11) de fluide, ainsi qu'un filtre (5) qui est placé dans une partie supérieure de la chambre de séparation (2) et qui sépare les particules et le fluide l'un de l'autre. Les particules séparées sont acheminées vers un orifice de sortie de particules (10) par lequel elles parviennent dans une chambre de collecte (13) par ailleurs séparée de la chambre de séparation (2). Le fond (41) de la chambre de séparation est plan ou bombé en direction du filtre (5). On obtient ainsi un très petit dispositif dans lequel les particules et le fluide peuvent être effectivement séparés l'un de l'autre. En outre, lesdites particules sont très faciles à enlever du dispositif.
