Definitions

  • the invention relates to filter cleaning for vacuum cleaners by means of pressure surge according to the preamble of claim 1.
  • Filter cleanings for vacuum cleaners of the type mentioned at the outset are known become where the cleaning by means of externally generated and the Vacuum cleaner of compressed air is carried out. In some use cases but an external, high-tension compressed air is not available and it has to go after Replacement solutions are sought. It is mechanical cleaning known, but the efficiency of cleaning with compressed air inferior.
  • the invention is therefore based on the object, a method and a Device for filter cleaning for vacuum cleaners by means of pressure surge to further develop the cleaning of the filter without the addition of external Compressed air can be done.
  • An essential feature of the invention is that the filter cleaning for Vacuum cleaner is done by pressure surge and that the pressure surge is either inside a container from / in the vacuum cleaner via a pyrotechnic propellant or from a prestressed gas, which is in a container on / in the vacuum cleaner is arranged, is removed.
  • the strength of the cleaning can be quite accurate according to the propellant charge be dosed.
  • the quantities required for this are proportional low.
  • the control for cleaning can be according to the contamination of the filter be made electrically or electronically. After the corresponding The filter's contamination indicator could then be the pressure surge Cleaning can be triggered automatically.
  • Magazines with corresponding propellant charges are also for propellant charges
  • Refillable pressure vessels are provided, which are preferably in the one-way system be used. The number and size depends on the Operating conditions.
  • a is used as a pyrotechnic propellant Blank cartridge or a number of blank cartridges preferred over a corresponding mechanical or electrical detonator each ignited become.
  • the blank cartridge can be conveyed from an existing magazine and transported into an appropriate pressure chamber, where they can be ignited mechanically, electrically or electronically.
  • this gas is stored in a corresponding pressure vessel, which gas can be, for example, air, carbon dioxide (CO 2 ) or nitrogen (N 2 ). Of course, all other gases can also be used. Likewise, the development of a gas can also be provided in the pressure vessel. Such gas developers are known, for example, on the basis of carbide gas and can be used advantageously here.
  • Carbon dioxide cartridges known per se can also be used, such as it for some applications (e.g. for beverage preparation or Whipped cream preparation) are known. Also contain these carbon dioxide containers on a small volume a high proportion of air that is suitable, the filter jerkily of the vacuum cleaner.
  • a dirt suction container 1 is generally shown, which in itself known manner has a connecting flange 2 through which the suction air in Arrow direction 25 is sucked into the container 1.
  • the one with dirt Suction air is deposited on the outside 10 of a filter 3, so that on this filter 3 forms a dirt coating 11.
  • the filter 3 is otherwise sealed with its bottom 4 below.
  • a pressure vessel 8 is used for cleaning provided with a high-tension gas, such as. B. air, carbon dioxide or nitrogen.
  • a high-tension gas such as. B. air, carbon dioxide or nitrogen.
  • the pressure in this pressure vessel 8 can be in the range be from 1 to 150 bar and the container 8 is closed by a valve 9, which can be opened suddenly, for example, electromagnetically or electrically is.
  • a supply line 16 attaches to the pressure vessel 8 and leads to the clean air side of the filter 3 opens into a pressure tube 17 which has openings 18.
  • valve 9 If the valve 9 is suddenly opened for a specific, very short time, then the gaseous pressure medium flows suddenly out of the pressure vessel 8 via the feed line 16 in the pressure pipe 17, and this pressure surge of Print medium is passed in the arrow directions 19 on the filter 3, so that the Pressure surge penetrates the filter 3 and the adhering to the outside 10 Debris 11 separates, which then in the direction of arrow 12 to the bottom of the Vacuum cleaner container 1 falls.
  • a Check valve 13 is arranged, which itself when the pressure surge unfolds closes automatically, but is otherwise open so that the pressure surge does not can escape to the outside via the exhaust port 7.
  • a check valve 14 is provided to also prevent the escape of the Avoid pressure surge on the connection flange 2.
  • the invention is of course not based on the arrangement of a pressure pipe 17th limited on the clean air side of the filter 3.
  • the filter 3 themselves have corresponding compressed air bores, so that the pressure pipe 17th is formed by parts of the filter 3 itself.
  • the pressure surge also occurs via a propellant charge 21 can be triggered, e.g. is designed as a blank cartridge.
  • This propellant 21 is arranged in a pressure vessel 20, which in turn via the feed line 16 is connected to the pressure pipe 17 or the pressure pipe arrangement 27 according to FIG. 3.
  • the propellant charge 21 is triggered via the primer 22, which for example mechanically ignited by a spring-loaded pin 23 and thus triggers propellant 21.
  • the pressure surge is then in the direction of arrow 24 into the pressure pipe 17 or 27 initiated.
  • Figure 3 shows another and modified embodiment, where inside of the filter 3, a pressure pipe arrangement 27 is arranged, which via distribution pipes 28 is centrally connected to a feed line.
  • the pressure surge is thus given in the center of the distribution pipes 28 and goes then radially outward into the radially outer pressure tubes 27, where he is evenly distributed on the inside of the filter 3.
  • the pressure pipe 17 is eccentric with respect to the central axis of the filter 3 is arranged and is rotatable. It can therefore be on the inside the filter 3 can be moved step by step, and with each step can then a corresponding pressure surge can be input to the pressure pipe 17 to clean the corresponding sector section of the filter 3.
  • a distributor arrangement of the shape can be provided in FIG. that stepwise onto the respective radially arranged distributor pipes 28 is switched that only a single distributor pipe 28 with the attached connected pressure pipe 17 is in operation and only the filter 3 by sector is cleaned.
