Definitions

  • the invention relates to a device for cleaning a powder coating booth and a powder coating booth with cleaning device.
  • the object to be coated In the electrostatic coating of objects with powder this is sprayed on a powder spray gun on the object to be coated.
  • the objects to be coated are usually located within a booth during the coating process. Since during the coating process not all powder particles sprayed by the spray gun stick to the parts to be coated, the excess powder, which is also referred to as overspray, must be removed from the booth. This is necessary on the one hand because the environment outside the cabin is to be kept free of powder dust. On the other hand, the danger of explosion when exceeding a certain powder concentration by the powder dust cloud floating in the cabin increases. This should be avoided. Another reason for removing excess powder from the interior of the cabin during operation is that the additionally required cleaning measures during the color change take less time, if the cabin has already been largely freed of excess powder.
  • a paint spray booth for powder coating is known in which excess paint particles are conveyed into a centrally located at the bottom of the cabin suction, for which purpose two horizontally directed transverse air streams are provided.
  • the crossflow streams are created by blowing air into the cabin through horizontal slots in the sidewalls of the paint spray booth.
  • the paint spray booth has, on each outer side, a nozzle formed by a sheet-metal shaped part, through which the air flow generated by a fan is directed into the interior of the paint spray booth.
  • such an embodiment for cleaning the cabin floor has the disadvantage that the width of the cabin considerably increases due to the sheet-metal molded parts which are laterally attached outside to the paint spray booth.
  • the longitudinal sides of the cabin openings must have in the form of slots for the sheet metal parts. If it is not possible to suck sufficient secondary air from outside through these openings and to blow into the cabin, in addition, the openings must be sealed after installation of the sheet metal parts to prevent them from exiting through the powder from the cabin.
  • the powder spray coating booth has a Absaugkanalan whatsoever at the bottom of the cabin interior for the extraction of air and excess powder from the cabin interior.
  • the suction channel arrangement is designed so that at the lower end of the cabin interior along the object transport path results in a non-uniform distribution of the suction air flow. This is achieved by the fact that along the ptransportweges the majority of the exhaust air flow through exhaust passages, which are arranged close to the wall passages for the objects in the cabin space and thus at the two ends of the cabin, flows out of the cabin space.
  • the existing in the cabin suction is covered by two adjustable channel cover parts.
  • compressed air distribution lines are provided in the cabin, via which the excess powder is blown by means of compressed air in the direction of the suction channel.
  • such an embodiment has the disadvantage that mechanically moving parts are present, whereby the susceptibility is increased.
  • the interior of the cabin is difficult to walk on through the two movable channel cover parts and on the other hand due to the incline in the cabin floor.
  • An object of the invention is to provide a device for cleaning a powder coating booth and a powder coating booth with cleaning device, in which the cabin floor is easily accessible and also an efficient and extremely effective cabin cleaning is guaranteed.
  • the object is achieved by a device for cleaning a powder coating booth with the features according to claim 1.

  • a suction channel which has a suction slot, is provided to suck off excess powder, wherein the first and the second air-blowing strip are provided in order to blow excess powder in the direction of the suction slot.
  • the first and / or the second and / or the third air-blowing strip has a plurality of strip sections, via which air can be blown independently of one another. In this way, the entire area to be cleaned can be divided into individual segments, which are cleaned in due course. Thus, if the individual segments are cleaned one after the other, the total air consumption per unit of time can be reduced. Furthermore, this reduces the noise level.
  • the powder coating booth with cleaning device has a first air blow strip, which is arranged at the bottom of the powder coating booth, and a second air blow strip, which is arranged on one side of the powder coating booth.
  • the powder coating booth has a first suction channel, which has a suction slot, wherein the first and the second air strip are provided to blow excess powder in the direction of the suction slot.
  • a third air blowing strip is provided for a second side of the powder coating booth. Furthermore, a second suction channel, which has a suction slot, is provided, wherein the third air blowing strip is provided in order to blow excess powder in the direction of the suction slot of the second suction channel. This further increases the efficiency of cleaning and the cleanable area.

  • the first and / or the second and / or the third air blowing strip has a plurality of nozzles which are arranged such that the air flow generated by the nozzles propagates substantially transversely to the longitudinal axis of the air blowing strip. As a result, a sufficiently large and evenly distributed air flow can be generated.
  • the nozzles of the first air blast strip can be arranged such that the air flow that can be generated by the nozzles is aligned substantially parallel to the ground. This allows the soil to be rid of the excess powder evenly.

  • the first and / or the second and / or the third air blowing strip extends substantially over the length of the bottom of the powder coating booth. This allows the entire floor in the powder coating booth to be cleaned.
  • the first air bomber can be arranged in the middle of the floor. This has the advantage that a uniform cleaning of the soil is achieved with minimal compressed air demand.
  • the first and / or the second and / or the third air baffle can be made of plastic, preferably PVC, POM or Teflon® . This minimizes the adhesion of excess powder to the air blast bars.
  • the suction slot is located between the side and the bottom of the powder coating booth. This has the advantage that the bottom of the powder coating booth can be lowered further, without resulting in performance losses during cleaning.
  • a second suction channel having a suction slot is provided, wherein the first and the second suction channel extending along the longitudinal side of the powder coating booth.
  • a slope in the cabin forms the transition between the side and the floor.

This has the advantage that with the help of the second and / or the third air blow bar, the slope or bevels in the cabin and with the aid of the first air blow strip the floor in the cabin can be cleaned. Behind the slopes there is also sufficient space for the installation of both extraction channels.
  • the nozzles of the second and / or the third air blast strip are aligned such that the air flow that can be generated by the nozzles is aligned substantially parallel to the slope. This increases the efficiency of the airflow during cleaning.
  • the second air blast strip is integrated into the side wall of the powder coating booth and forms a flat surface therewith. This allows a deposit Avoid excess powder on the second breather.
