Definitions
- the invention relates to a method for operating an electrostatic
- Particulate collector an electrostatic particle collector according to the preamble of claim 13 and a particle collection system.
- the particles according to the invention are in particular dust, e.g. House dust, and any other electrostatically collectable particles, e.g. those typically found in areas inhabited or occupied by industry, such as human or animal hair, particles of clothing, soil particles, pollen, and the like.
- dust e.g. House dust
- any other electrostatically collectable particles e.g. those typically found in areas inhabited or occupied by industry, such as human or animal hair, particles of clothing, soil particles, pollen, and the like.
- Electrostatic particle collectors have compared to the long-known
- Vacuum cleaners a low power consumption, lower noise and do not whirl up the particles, especially house dust, pollen and possible other allergy-relevant substances, which is particularly advantageous for allergy sufferers.
- Particle collector of the type mentioned which has arranged in a wiping area within a flat tail electrode, whose
- a voltage can be applied to the electrodes by means of a battery, and thus an electrostatic field can be built up in the wiping area.
- the electrostatic field creates a polarization in particles that are within range of the field, resulting in an electrical force of attraction between the particles and the particle collector.
- Around the electrodes is laid a cloth or paper to which the polarized particles adhere.
- the electrostatic field is turned off. To dispose of the collected particles is provided to remove the cloth or the paper from the particle collector and throw away together with the particles. Without the cloth or paper, the particles would adhere directly to the electrodes. These would each have to be cleaned consuming. The latter would be problematic, since even with separation of the battery from the electrodes, the polarization the particle and thus the attraction between the particles and the
- Particle collector is retained for a long time.
- an electrostatic dust collector is disclosed as a particle collector with two electrodes, which are supplied with voltage by means of a high voltage source arranged in the particle collector.
- a duster can be disposed of with the electrostatically adhering dust.
- cover the electrodes with a smooth, electrically non-conductive material, to which the dust is fixed during collection. In this case, the collected dust by stripping or after discharge of the electrodes by simple
- Tapping can be removed from the dust collector. Since, as stated above, the polarization of the particles is retained for a long time, it is to be expected, however, that during stripping or tapping a considerable part of the particles remains on the coated electrodes or is attracted to the particle collector again. In any case, the removal of the dust has to be done manually both when removing a duster and when washing or tapping. The dust carrying capacity of the described device is limited, so that a disposal of the
- Particle system results from the features of claim 23.
- the method according to the invention is characterized in particular by the fact that the collected particles are first of all introduced into at least one particle
- Particle collectors arranged particle catcher are stored and the particle catcher is emptied in a disposal process.
- Collecting segment can put the collected particles into the particle catcher until it is filled.
- the collection process does not need to be interrupted in order to dispose of a duster around the electrodes with the adhering particles each time or to clean the electrodes manually when the
- the inventive method is characterized by a special procedure during the Operachenablegevorgangs. Accordingly, the absolute value of the potential difference between the electrodes is reduced and the sign of the potential difference is changed at least once.
- Procedure can cause a significantly improved deposition behavior.
- the change of the sign of the potential difference counteracts the tendency, after switching off the potential difference to obtain a residual polarization in the particles, which persist over a longer period of time and thus for a
- the electrodes Since the electrostatic field generally reaches maximum values in the area of the electrodes, the adhesion capacity for polarized particles increases with proximity to the electrodes. It may therefore be advantageous for the electrodes to be as dense as possible
- Each electrode may be e.g. branch into multiple electrode arms, e.g. Electrode arms of the first electrode of a pair of electrodes in between electrode arms of the second electrode of the pair can grip.
- Electrodes It is also advantageous to protect the electrodes from direct contact with the particles or other foreign bodies to be collected by means of a coating, a foil or other delimitation. As a result, electrical short circuits can be avoided. In particular, the cleaning of damp dirt is possible and the contact of the particle collector with befindlichem on the surface to be cleaned water harmless.
- Another demarcation can also be realized by a matrix material, for example of insulating plastic, which surrounds the electrodes. It may also be advantageous to carry out the method according to the invention in such a way that at least one further electrode pair is used to generate the electrostatic attraction in the same collecting segment. This allows the

- a disposal device at which the at least one particle collecting container is emptied.
- This can be done pneumatically, for example by a suction device.
- the pneumatic emptying can be carried out fully automatically, for example by a precise docking of the particle collector to the
- the deposition takes place, for example, at an access to
- the particle collector is driven in a reverse operation.
- the above-described method for lowering the potential difference is preferably carried out, namely a lowering of the absolute value of the potential difference when changing its sign.
- the particle collecting container avoids whirling up of the particles. If necessary, a mechanical scraper can also be used.
- Part of the bottom of the particle catcher at least partially mechanically rid of particles. This can also be done by a scraper. The particles are thus pushed together and can then be easily sucked off. It is also conceivable to push the particles by means of the scraper in the direction of an opening in the particle collecting container, through which the particles then pass into the disposal device. Such an opening may be closable for the collection operation, e.g. a closed in the collection process by spring force or by other mechanisms flap in a side wall of the particle collecting container, which is automatically opened by the movement of the scraper or when entering the disposal facility.
- the particle collecting container can also be moved.
- At least two collection segments each having at least one pair of electrodes.
- at least one of the collecting segments is in the particle collecting process, while at least one other of the collecting segments in the
- Particle laying process is located. In this way, a continuous collection process is possible, since one of the collection segments can always be located in the particle collection process.
- the particle collector as a self-propelled device, in particular as a robot.
- the collection segments may be part of an endless belt which runs continuously through a collection area and through a deposit area. In the collection area The particles are absorbed by the collecting segments of the surface to be cleaned and stored in the depositing area in the particle collecting container.
- the collecting segments may be part of a circular disc which rotates about an axis perpendicular to the disc and to the surface to be cleaned.
- Rotational motion may be continuous with constant direction of rotation or discontinuous with direction of rotation reversed. In the case of continuous
- At least one collecting segment which has a front angle in the direction of travel of the particle collector, which is preferably pointed or rectangular. This makes it possible to clean the surfaces in the region corresponding to angled corners of a room in a particularly advantageous manner. It is important to ensure that any existing, the collecting segment or the collecting segments overlapping housing is shaped accordingly, so that the relevant collection segment and the tip of the corner at least almost reached.
- an angle adjustment unit with which the orientation of the front angle relative to the travel direction or relative to the chassis is variable, e.g. by a rotational or pivoting movement of the relevant collecting segment about an axis perpendicular to its collecting surface. The orientation of the angle can vary depending on the direction of travel of the
- Particle collectors relative to the orientation of the corner to be cleaned are made such that the orientation of the front angle of the collecting segment for aligning the corner fits, the corner is thus completely covered by the collecting segment.
- any geometry of the collection segments are conceivable. It is also conceivable that the collecting segment or the collecting segments in their geometry
- the collecting segment can consist, for example, of a plastically deformable matrix material with incorporated electrodes.
- a variability can be realized, for example, via one or more expansion regions, which can be stretched or compressed analogously to a bellows.
- the collecting surface provided collecting surface of the collecting element is located in at least two mutually parallel planes.
- the quilt could thus be e.g. be bent to a right angle, for example, to clean stairs.
- the electrodes can also be made hinged in parts.
- the collection segment can also be designed such that the line of the folding runs solely through electrode-free regions of the collection segment.

- the particles 24 contained in the particle collecting container 50 can be electrostatically absorbed and outside the particle collecting container 50 after a corresponding change in the position of the collecting collecting segment 47 or 48 via a disposal container, not shown here, of the type described above and way of lowering the potential of the electrodes not shown here are stored.
- the particles collected in the Pumbleauffangbehalter 50 particles 24 can be pushed together by means of a sliding element in a disposal position and sucked there or via a not shown here closable opening in the
- Particle catcher 50 are emptied into a disposal container.
- the particle collector 46 can also be connected to a suction station 58, which covers the Prismauffangbehalter 50 with its front piece 59 and the Prismauffangbehalter emptied pneumatically in this way.
