Definitions
- the invention relates to a surface cleaning device for dedusting solid bodies, in particular for pre-cleaning surfaces before painting.
- the object of the invention is to provide a surface cleaning device which allows rapid, thorough dedusting of different solid bodies with little effort and largely eliminates the disadvantages mentioned above.
- This object is achieved by a surface cleaning device with the features according to the patent claims.
- the surface cleaning device according to the invention essentially comprises a blowing air nozzle with a narrow, obliquely arranged linear blowing slot, which is operatively connected to an ionizing device, a suction air nozzle with a linear suction slot and a baffle in such a way that it has a thin, flat, laminar one Emits air jet at high speed, which can brush the surface to be cleaned vigorously and is then sucked off through the linear suction slot.
- This brush is preferably a toothed strip brush and, according to the invention, fulfills various tasks: firstly, it serves as a baffle and a spacer in order to limit the laminar air jet and thus to ensure an optimal cleaning effect while largely avoiding the extraction of ambient air. Secondly, it serves as a protective brush to prevent any damage to the surface to be cleaned or the device. With this brush, adhesive and slurry dust can also be mechanically detached from the surface to be cleaned and then vacuumed off.
- the blowing air nozzle is dimensioned accordingly, adapted to the desired air speed and advantageously provided with internal guide surfaces so that the blowing air is evenly distributed and directed obliquely so that no turbulence occurs in the air jet.
- the blowing air can flow through the linear blowing slot in the form of a flat, very thin laminar air jet over the entire slot length with a slight excess pressure of less than 1 bar, preferably less than 0.5 bar, with a relatively short jet length and are fed obliquely to the surface to be cleaned in order to ensure a laminar flow along this surface.
- the blown air can be generated in a ring compressor located outside the cleaning device and fed to the blown air nozzle via a low-pressure hose, the suction air being discharged from the suction air nozzle through a suction hose.
- the length and shape of the suction slot are adapted to the blow slot and designed so that the suction air nozzle can suck off a somewhat larger amount of suction air than the amount of blow air emitted without considerable pressure loss.
- the suction air is preferably fed to a high-performance filter, wherein cleaned air is fed to the suction side of the compressor and is returned to the blower air nozzle via this.
- FIG. 1 schematically shows a portable surface cleaning device according to the invention in section, through a vertical central plane.
- FIG. 3 schematically shows a partial view of the floor plan of the industrial cleaning device according to FIG. 2.
- the portable cleaning device comprises a housing 14 with a handle 15 for carrying and guiding the device, a built-in blow air nozzle 1 with an obliquely arranged, linear blow slot 2 on the underside of the device, and an ionizing device 7 also built into the device , which is in operative connection with the blowing air nozzle 1, a suction air nozzle 3 with a suction slot 4, which is arranged at a short distance X from the blowing slot 2 on the underside of the device, and a flat brush 5, preferably a toothed strip brush, which is located next to the suction slot 4 is arranged and protrudes at a height H in relation to the outlet of the blow slot 2 from the underside of the device.
- the brush 5 is attached to the device by suitable means, not shown, which allow it to be replaced and its height H to be set as desired.
- the blow air nozzle 1 and the blow slot 2 are dimensioned and designed such that a flat, laminar air jet is emitted through the blow slot 2 at high speed.
- the blow slot 2 is arranged obliquely with respect to the suction slot 4 and on the underside of the device, so that it can direct a laminar air jet at a small acute angle onto the surface to be cleaned, which is in contact with the lower surface free end of the brush 5 at height H will limit the cleaning gap parallel to the bottom of the device.
- the mode of operation of the described portable cleaning device according to FIG. 1 can be explained as follows:
- the portable cleaning device is worn on the handle 15 and guided along the surface to be cleaned in such a way that the free end of the brush 5 is always kept in contact with this surface.
- the brush 5 should be perpendicular to this surface, so that the underside of the device is parallel to the surface to be cleaned.
- the height H of the brush 5 thus determines the desired distance between the underside of the portable device and the surface to be cleaned and limits this with a narrow cleaning gap which includes the laminar air jet emitted by the blow slot 2.
- the air jet can be maintained with a laminar flow at high speed along the surface to be cleaned through the cleaning gap, the brush 5 laterally delimiting this cleaning gap, determining its gap width and largely preventing unwanted suction of ambient air.
- This laminar flow of high speed can thus brush the surface to be cleaned vigorously, detach or entrain dust particles located on it, immediately afterwards by the suction device and suck it off with the detached dust particles.
- the built-in ionizing device 7 makes it possible to continuously generate positive or negative ions in the blown air stream.
- electrostatically charged particles on the surface to be cleaned can be neutralized, detached and removed by the ionized blown air stream.
- the blowing air nozzle and the suction nozzle of the portable cleaning device according to the invention can have a variable width, which by appropriate mechanical adjusting means, for. B. with the help of articulated arms and toothed drive either by hand or with a motor to adjust the width of the two nozzles individually or together as desired.
- the blow slot or the suction slot of these nozzles can also be equipped with adjustable guide lips or other suitable means in order to vary their gap width as desired.
- a mechanical fine adjustment of the gap width can optionally be provided.
- additional brushes can be provided on the cleaning device, for example to limit the laminar flow of the air jet laterally, so that lateral suction of ambient air is avoided.
- sensors and display means can be assigned to the portable cleaning device according to the invention, for example to allow a display of the back pressure on the brush, an air pressure display for the purpose of optimizing the blown air / suction air household or a display of the positive or negative charge on the surface.
- the cleaning device can be made of any suitable metal.
- the portable cleaning device according to the invention has numerous advantages, for example simple handling, versatile uses with relatively low purchase costs, minimal weight and very small space requirements. It also allows a significant simplification and labor savings in cleaning work while avoiding the aforementioned finishing work on painting. It is also particularly environmentally friendly.
- the industrial surface cleaning device comprises * a connection 20 with a receiving center 21 for storing and rotating the device.
- the industrial cleaning device according to FIG. 2 comprises a built-in blowing air nozzle 1 with an obliquely arranged blowing slot 2 on the underside of the device, an ionizing device 7, which is in operative connection with the blowing air nozzle 1, a two-piece toothed strip brush 25, which are at a distance Z and Z.
- Blowing air nozzle 1 stands, divided and offset in the middle and an obliquely arranged suction air nozzle 3 with a suction slot 4, which is at a short distance X from the strip brush 25, this in front of the suction air nozzle 3 with a height H with respect to the leading edge of the Suction slot 4 protrudes from the underside of the device.
- the strip brush 25 is attached to the device by suitable means, not shown, which allow it to give an oscillating movement on the one hand and to replace it on the other hand and to adjust its height H as desired.
- the blown air nozzle 1 is connected to an attached blown air duct 29 which has an inlet 30 with a protruding part 31 for connection to a blown air hose 16 shown in dashed lines, this serving for supplying compressed air.
- the suction nozzle 3 is also connected to an attached suction air duct 32, which is connected to connecting pieces 33 which lead to a central tube 34.
- This pipe 34 has an outlet 35 with a protruding end part 36 for connection to a suction air hose 18 shown in dashed lines, this serving for suctioning the cleaning air at a corresponding negative pressure.
- the blow air nozzle 1 and the blow slot 2 are dimensioned and designed in such a way that a flat, laminar air jet is emitted through the blow slot 2 at high speed, corresponding pressure and a suitable range.
- the blow slot 2 is arranged obliquely so that it can direct the laminar air jet onto the surface to be cleaned with the appropriate acute angle.
- the obliquely arranged linear blow slot of the blowing air nozzle provided according to the invention is achieved with an acute angle of attack of e.g. B. directed 25 ° to 60 ° to the surface to be cleaned so that a laminar flow of the air jet emitted by the blow slot on the surface to be cleaned can be ensured.
- the blow slot is arranged at an appropriate angle with the underside of the device and with the central plane of the suction slot and is dimensioned accordingly.
- the laminar flow is also ensured by the height of the chicane or the strip brush, in that it limits the narrowest possible cleaning gap between the blow slot or the underside of the device and the surface to be cleaned.
