Definitions
- the invention relates to a device for sucking and filtering fine dust polluted air with at least one arranged in a filter chamber
- Filter cartridge having an inner cartridge cavity surrounding
- Filter wall outer surface is blown off, so that the blown fine dust in at least one particulate matter collection chamber comes down to be removed from there.
- the object of the invention is to improve a device of the type mentioned above so that in a simple, easy to handle, space-saving and mobile construction safe disposal of particulate matter is given without fine particulate matter can escape to the outside. It is also the task of
- CONFIRMATION COPY Invention to achieve a safe internal disposal of particulate matter within the device.
- Fine dust collecting chamber is guided by the fine dust in the
- Substantially freed air in the circuit returns to the particulate matter collection chamber.
- Locking system is connected, after the decrease of the
- Fine dust container / the cartridge from the fine dust automatically closes the opening of the fine dust container.
- the air loaded with fine dust above the filter cartridge is rotated by a tangential feed and / or by a slanted wing having rotary encoder in rotation, so that the loaded air encircles the filter cartridge outside helically.
- Annular space in the particulate matter collecting chamber is improved when in the bottom of the filter cartridge surrounding annular space in particular radially arranged openings are arranged as particulate traps through which the particulate matter in the arranged underneath fine particulate collection chamber passes.
- the openings acting as fine dust traps should have sloping inflow surfaces.
- a safe emptying of the particulate matter collecting chamber is achieved when in the annular particulate matter collecting nozzle obliquely oblique, in particular tangentially open so that blown through the blowing nozzles air in the
- Particulate dust collecting air is stirred up together with the fine dust collected there to be transported by the dust line. This ensures that the opening (s) are closed.
- Fine dust receptacle in particular in the form of a replaceable
- Cartridge be attached, so that an easily manageable mobile device of small external dimensions is created.
- wheels may be attached to the process on the underside of the device.
- the device / device has a
- FIG. 1 shows a first embodiment with an arrangement of filter cartridge
- Particulate matter collection chamber and fans among each other in a housing or frame and a particulate matter separator with detachable receptacle attached to the back of the housing, 2 shows a horizontal section according to AA in Fig. 1,
- Fig. 3 shows a second embodiment with safe emptying of
- Fig. 4 is an enlarged view of the particulate matter collecting chamber
- the device (the device) for sucking and filtering air contaminated with fine dust is preferably a movable unit with a housing 1 or frame, which has three to four wheels 2 on its underside.
- Housing surrounds at least one filter cartridge 3, which has a cylindrical, vertical filter wall 6 made of folded filter material. Between the housing wall and the filter wall 6 there is an annular space 4, in which sucked on the top of the housing, loaded with particulate air 5 passes to pass from the outside in through the filter wall 6 into the cylindrical, closed at the top of the interior 8 of the filter cartridge , Here, the fine dust deposits on the outside of the filter cartridge.
- a bow-shaped, compressed air leading pipe 9 is rotatably mounted about a vertical axis coaxial with the filter cartridge axis, wherein the tube parallel to the axis, the
- Filter cartridge inner wall has close pipe section 9a, which has on its side facing the pipe wall outside a series of mutually arranged outlet openings in particular nozzles 10.
- Tube section 9a penetrates the compressed air emerging from the nozzle from the inside to the outside of the filter wall and thereby dissolves the fine dust which has settled on the outside of the filter wall 6, in particular in its folds.
- the thereby separated from the filter outer wall fine dust reaches down to the bottom 11 of the annular space 4 and passes through radial, slit-shaped
- Openings 12 of the bottom 11 pass into a particulate matter collection chamber 13 located below the bottom which annularly surrounds a central vertical channel 14 extending downwardly from the cartridge interior 8 to a fan 15 located below the particulate matter collection chamber.
- the fan sucks the air 5 through the filter cartridge 3 through and blows them cleaned outward into the room in which the device / device is.
- the openings 12 in the bottom 11 each have an oblique inflow surface 16 at the radial opening edge, whereby the openings form dust traps, is intercepted by the circulating around the filter cartridge 3 fine dust and fed into the fine dust collection chamber 13.
- a dust line 17 is connected, through which the particulate matter accumulated in the particulate matter collecting chamber is transported to a fine dust separator 18.
- Fine dust is introduced and swirled in the fine dust to a cyclone 9, whereby the fine dust particles secrete to the outside of the air and reach down into a particulate matter receptacle 20 and accumulate there.
- the fine dust receiving container 20 is detachably attached to the fine dust separator 18 and is disposed of after complete filling, in particular burned in a waste incineration plant. For this purpose exists the
- Fine dust container preferably from a cartridge made of combustible material, in particular cardboard.
- the particulate matter storage container is closed at its top by a film or membrane 21, of a on the
- the opening in the film / membrane 21 is such elastic and / or designed so that after removing the
- Fine dust receptacle closes the opening on its own and one
- the bottom of the particulate matter collection chamber forms a funnel that enters the
- Dust-discharge pipe 22 opens. On the outside of the
- Particulate matter receiving container 20 is a level sensor 23, which is attached to the back of the device / the device.
- the beginning of an air return line 24 emerges, which returns the air in the interior of the cyclone, less polluted by fine dust to the particulate matter collection chamber 13.
- the dust line 17 thus forms, together with the return line 24, an air circuit for transporting the fine dust from the fine dust collecting chamber 13 to the fine dust separator 18.
- the drive of this cycle is effected by a vacuum conveyor 25, which preferably has a Venturi nozzle with a compressed air connection.
- the fine dust is an integral part of the movable device and the particulate matter receptacle is particularly easy to reach as a cartridge.
- Return line 24 does not open into the particulate matter collection chamber 13, but in the annular space 4, which surrounds the filter cartridge 3 and forms the Rohluftseite.
- the particulate matter collection chamber 13 is designed as follows:
- the opening or openings 2 are in the first embodiment as
- Fine dust traps designed radially.
- these openings 12 may also be radial, but preferably there is an annular opening 12 coaxial with the filter cartridge axis and closable.
- the opening 12 is closed by an inflatable tube seal 27 having a hose, a hose sector 26 or a membrane which is loaded by air pressure on the back, thereby closing the opening 12.
- both the closed and the open position is shown.
- annular particulate matter collecting chamber 13 not shown compressed air nozzles or nozzles that open obliquely, in particular tangentially into the annular chamber 13 and thereby raise the collected dust in the chamber 13 to one and put the other in a rotating movement along the annular chamber.
- the particulate matter that is thereby whirled up is transported almost completely through the fine dust line 7 to the fine dust separator 18.
- This construction is preferably operated in such a manner that, after sufficient particulate matter has entered the chamber 13, air is not injected through the blast nozzles into the chamber 13 until after the opening (s) 12 have been closed. As long as the opening (s) 12 are opened, the falling of the outside of the filter cartridge 3 particulate enters the
- the particulate matter collection chamber 13 thus operates alternately with the opening or openings 12 open to receive particulate matter from the annular space 4, (This particulate matter is particularly incurred when is blown through the compressed air nozzles 10 from the inside out through the filter cartridge 3 to blow out of the filter cartridge deposited fine dust) and then at
