Definitions

  • the present invention relates to a suction system for powdery material, in particular for powder coating booths with at least one moving suction nozzle, at least one suction air duct with a suction blower that is operatively connected to the suction nozzle, and a powder coating booth with floor filter and movable suction nozzle, floor pan and suction fan, which according to the European patent application No. O 141 778 is suitable for transporting sprayed powder back into the dispensing container in the shortest possible way.
  • the cabin described in this application has certain problems with the transition from the longitudinally moving nozzle to the suction system.
  • the filter belt is stationary during the coating.
  • a nozzle travels back and forth along the entire length of the belt, with the powder that has fallen down being collected through slots.
  • a connection by means of a hose from this nozzle to the outside has the disadvantage that the hose is always in the area of the coating, which can lead to faults.
  • the invention offers an optimal solution for the airway of the suction and cleaning as well as further advantageous technical solutions that simplify the color change.
  • the known electrostatic powder coating system 1 shown in FIG. 1 is provided with a cabin 2 in which a device 3 for dispensing electrostatically charged powder is arranged.
  • a filter belt 5 movable through the cabin 2 is provided on the bottom side 10.
  • a first suction fan 35 is connected over a large area in the area of the floor 10 of the cabin 2. It creates a suction field with negative pressure through the filter belt 5 in the cabin 2.
  • a cleaning device 13 assigned to the filter belt 5 serves to remove the excess powder lying on the filter belt 5.
  • actuating means 6, 7 enable the filter band 5 to be retightened by at least one cabin length and thus to assign each filter color to its filter band zone.
  • This multicolor booth represents an optimum in terms of expenditure and time.
  • the powder recovery system is also shown for the sake of completeness, although it does not affect the present invention.
  • Fig. 2 shows the side view of the cabin 2. Its coating space 51 is surrounded by sheet metal walls. A band-shaped bottom filter 52 is fixed on rollers 53 at both ends. The exhaust air is led into the open via a floor pan 58 and an exhaust air duct 59 via a fan, corresponding to the fan 35 in FIG. 1.
  • a suction nozzle 56 is provided, which is driven by a drive with one or two drive belts 54 and a motor 55 via the bottom filter 52 is moved back and forth.
  • the two opposing belts 54 designed as toothed belts, are coupled by a connecting shaft (not shown) in order to obtain synchronous running.
  • FIG. 4 shows the construction of the bottom filter 52 and the bottom pan 58. It is important for such a system that the air distribution at the bottom filter 52 for the suction is uniform in order to prevent overloading of the individual filter belt segments.
  • the cabin floor When cleaning and changing the color, the cabin floor must be accessible. All of these requirements can best be achieved by covering the floor pan 58 with a perforated plate 61 of approximately 5-20 mm in diameter.
  • a plastic band 60 with, e.g. round or rectangular, openings of 3 - 10 mm in diameter or side length, so that the air flow is further improved and no damage occurs when changing color by rotating the rollers 53.
  • the nozzle 56 is placed in a so-called guide frame 63 (FIGS. 4, 5).
  • This guide frame 63 is firmly connected on both sides to the drive of the toothed belt 54.
  • the belt 54 is interrupted here and these free ends are connected via the guide frame 63 (Fig. 6).
  • the guide frame 63 is designed in such a way that a transition of the air to a longitudinal channel 57 via a guide frame end profile 65 is possible at the ends. This profile 65 extends to the beginning of the filter belt. Thereafter, the guide frame 63 consists of two parallel webs, into which nozzle elements 73 forming the nozzle 56 are inserted.
  • the suction nozzle 56 is constructed such that, depending on the bandwidth, it consists of one or more of these elements 73.
  • the reason for this measure is that the individual elements 73 optimally compensate for any unevenness and inaccuracies in the floor filter 52, e.g. of the edition, can adjust.
  • the elements 73 are provided with rubber lips 67 at the top and sides in order to obtain a better seal.
  • the nozzle elements 73 are made of e.g. round or square, made of profiles. Teflon pads 68 are attached to the underside so that the band abrasion and the friction remain as low as possible.
  • Longitudinal slots 64 for suction are either provided continuously with a width of approximately 2 to 10 mm, or in two rows, mutually offset, which results in improved cleaning.
  • the powder-air mixture is guided from the reciprocating suction nozzle 56 via the guide frame end profiles 65 into the longitudinal channel 57.
  • This consists of, for example, round or square profiles with a longitudinal slot 64 on the top.
  • the longitudinal slot 64 is also covered by the drive belt 54, which is sucked in by the negative pressure prevailing in the longitudinal channel 66 and thus seals.
  • the air-powder mixture is then brought into a recovery system (FIG. 1) via a suction nozzle 71.
  • a plurality of suction nozzles 71 are preferably attached to the longitudinal channel 57, since this allows the position of the suction system to be optimally selected.
  • a suction nozzle for the walls etc. can be connected to one of the supports 71.
  • a longitudinal channel 66 can be attached to both sides of the cabin (FIG. 3). When changing colors, it is then necessary to clean the nozzle elements and to switch from one longitudinal channel 66 to the other.
  • the suction unit can then be connected to the second longitudinal channel 66 or even be available as a second unit for the next color. This saves time when changing colors because the cleaning effort is reduced.
  • the longitudinal channels 57 are provided with lids 72 at the ends, so that the channel can be quickly cleaned by means of a brush if necessary.
  • Such covers 72 are also attached to the profiles 65 of the guide frame 63.
