Figure 1 shows a diagram of a machine 1 for picking up aluminum dust, with a pneumatic system and a separating system. In the pneumatic system, there is a main blower 3 with an outlet pipe 4, which is divided into a main duct 6 and an auxiliary duct 7. The division of the conveying air is effected by means of a flap 8, which is pivotable about an axis 5 by hand through a linkage or by means of an adjustment motor.
The main passage 6 opens into a main mouthpiece 9 and feeds a lateral annular nozzle 10, which can alter-nately be a plurality of nozzles extending over at least a part of the periphery, with compressed air, which blows the dust towards the centre of the main mouthpiece 9. The air, charged with aluminum dust, is there sucked up through a suction nozzle 13 (arranged centrally or eccentrically) into a main pipe 12.
Adjacent the main mouthpiece 9, there is provided an
- 2 -auxiliary nozzle 15 having a funnel 16 and a suction duct 17, which is constructed so as to be movable, e.g. in the form of a hose pipe. The suction duct 17 and the main suction pipe 12 converge into a common passage 19, an adjustment flap 20 being arranged at the conjunction in order to enable the air flows through the suction duct 17 and the main suction pipe 12 to be adjustable.
The common passage 19 extends into a cyclone inlet 22, in which there is located a movable, e.g. motor-driven, separating vane wheel 23. This wheel 23 slows down coarse pieces such as paper, parts of protective masks etc., while the conveying air, hardly hindered by the perforated sheet metal vanes 21 and carrying the aluminum dust, is distri-buted to three cyclones 24, 25 and 26. The coarse parts pass through the passage 27 for emptying, while the fine parts, which are separated in the multi-cyclone, are col-lected in a collecting hopper 26 and can be discharged therefrom. The three cyclones extend into a collecting hopper 28. The central suction pipes 30, 31 and 32 of the cyclones 24, 25 and 26 open into a cyclone outlet 34, which extends into a blower inlet duct 35, which leads to the inlet of the blower 3. No details of the manner of operation of this multi-cyclone are herein described, such as the division of the air, the spiral supply into the cyclones, the depth of the immersion tubes, referred to as discharge pipes, and the like, since these are well known to those skilled in the art.
The auxiliary duct 7 leads to a bag filter 38 having a chamber 39 and an outlet 40. In the chamber 39, filter bags 41 are suspended, in knpwn manner, adjacent one an-other, and, if required, one beyond the other. The fine powder is removable through the outlet 40, while the -exhaust air is guided through an exhaust air duct 43 into an exhaust air blower 45, which discharges the air, substantially purified of aluminum dust, into the atmosphere. Also, no further details are given herein with respect to the bag filter 38, such as for example the automatic cleaning by agitation of the filter bags, the replacement thereof, the use of corresponding fabrics etc., since these are also known to those skilled in the art.
In Figures 2 to 5, in which parts the same as those already described are indicated by the same reference numerals, can be seen a four-wheeled vehicle 50 having a driver's cab 52 and a chassis 53, on which the blower 3, the main mouthpiece 9 and the auxiliary nozzle 15 can be seen. Also, the collecting hopper 28 with the cyclones are schematically illustrated, as are also the bag filter 38 with the interior filter bags. Also, a drive assembly 55, which can also be seen in Figures 2 to 4, is shown with auxiliary assemblies 57.
The auxiliary nozzle 55 is arrangèd to be displaceable, by means of the movable suction duct 17, which e.g. is in the form of a hose pipe, the normal operating posi-tion being shown in full lines in Figure 5, that for the suction cleaning of recesses being shown in broken lines and that for the cleaning of raised ledges, e.g. oven surroundings, being shown in dot-dash lines.
A suction cleaning machine constructed as described above is capable of picking up fine aluminum dust, sep-arating it and thereby trapping it without discharging it again into the atmosphere at a different position.
However, it can also pick up other fine dusts, such as cement.
The common passage 19 extends into a cyclone inlet 22, in which there is located a movable, e.g. motor-driven, separating vane wheel 23. This wheel 23 slows down coarse pieces such as paper, parts of protective masks etc., while the conveying air, hardly hindered by the perforated sheet metal vanes 21 and carrying the aluminum dust, is distri-buted to three cyclones 24, 25 and 26. The coarse parts pass through the passage 27 for emptying, while the fine parts, which are separated in the multi-cyclone, are col-lected in a collecting hopper 26 and can be discharged therefrom. The three cyclones extend into a collecting hopper 28. The central suction pipes 30, 31 and 32 of the cyclones 24, 25 and 26 open into a cyclone outlet 34, which extends into a blower inlet duct 35, which leads to the inlet of the blower 3. No details of the manner of operation of this multi-cyclone are herein described, such as the division of the air, the spiral supply into the cyclones, the depth of the immersion tubes, referred to as discharge pipes, and the like, since these are well known to those skilled in the art.
The auxiliary duct 7 leads to a bag filter 38 having a chamber 39 and an outlet 40. In the chamber 39, filter bags 41 are suspended, in knpwn manner, adjacent one an-other, and, if required, one beyond the other. The fine powder is removable through the outlet 40, while the -exhaust air is guided through an exhaust air duct 43 into an exhaust air blower 45, which discharges the air, substantially purified of aluminum dust, into the atmosphere. Also, no further details are given herein with respect to the bag filter 38, such as for example the automatic cleaning by agitation of the filter bags, the replacement thereof, the use of corresponding fabrics etc., since these are also known to those skilled in the art.
In Figures 2 to 5, in which parts the same as those already described are indicated by the same reference numerals, can be seen a four-wheeled vehicle 50 having a driver's cab 52 and a chassis 53, on which the blower 3, the main mouthpiece 9 and the auxiliary nozzle 15 can be seen. Also, the collecting hopper 28 with the cyclones are schematically illustrated, as are also the bag filter 38 with the interior filter bags. Also, a drive assembly 55, which can also be seen in Figures 2 to 4, is shown with auxiliary assemblies 57.
The auxiliary nozzle 55 is arrangèd to be displaceable, by means of the movable suction duct 17, which e.g. is in the form of a hose pipe, the normal operating posi-tion being shown in full lines in Figure 5, that for the suction cleaning of recesses being shown in broken lines and that for the cleaning of raised ledges, e.g. oven surroundings, being shown in dot-dash lines.
A suction cleaning machine constructed as described above is capable of picking up fine aluminum dust, sep-arating it and thereby trapping it without discharging it again into the atmosphere at a different position.
However, it can also pick up other fine dusts, such as cement.
