Definitions
- the invention relates to a method for ventilating a treatment booth, in particular a painting or spray booth for painting objects such as vehicle bodies, in which the fresh air to be fed into the booth is supplied via an air-permeable blanket, an air supply chamber being arranged above the blanket and having a at a fresh air supply system connected supply air chamber is connected via at least one passage opening and in which the amount of fresh air flowing into the air supply chamber flows in controllably by changing the passage opening.
- the invention relates to a processing booth, in particular a painting and spray booth for painting objects such as vehicle bodies, with an air supply chamber arranged over an air-permeable ceiling, which extends essentially over the entire ceiling length of the cabin, and with one with the air supply chamber over at least an adjustable passage opening connected air chamber, which is connected to a fresh air supply system.
- a processing booth of the type mentioned is known from DE 29 32 392 C3.
- fresh air or processed exhaust air is guided into one or more supply air chambers via vertical supply air lines, which in turn are via horizontally arranged, adjustable flaps in through openings with an underlying one
- Air inlet chamber are connected.
- the air inlet chamber is arranged above an air-permeable ceiling of the spray booth.
- the desired amount of fresh air is supplied in a controlled manner via horizontally arranged flaps which are arranged in the through openings from the supply air chamber to the individual sections of the air supply chamber.
- exhaust air fans are arranged in the floor area of the treatment cabin, which extract the cabin air via a paint mist separator.
- a technical problem on which the invention is based is to provide a method for ventilating a treatment cabin, in which the amount of fresh air to be fed into the treatment cabin can be exactly determined.
- Fresh air supply system connected supply air chamber is connected via at least one passage opening and in which the amount of fresh air flowing into the air supply chamber is regulated by changing the passage opening by at least a part of the fresh air amount fed into the supply air chamber in the supply air chamber is forcibly guided parallel to the ceiling before a predetermined length the forced fresh air flows through the passage opening into the air supply chamber, and by measuring the parameters necessary for the determination of the fresh air volume flowing through in the end region of the forced guidance.
- Another technical problem on which the invention is based is to create a treatment booth in which limited height, the amount of fresh air flowing into the treatment cabin can be determined very precisely.
- a processing cabin with an air supply chamber arranged above an air-permeable ceiling, which extends essentially over the entire length of the cabin and which is connected via at least one adjustable passage opening to an air supply chamber connected to a fresh air supply system, in that at least one duct connected to the passage opening extends parallel to the ceiling over a predetermined length such that an inlet opening of the duct, through which the fresh air introduced into the supply air chamber flows into the duct, extends partly or entirely over the entire width and partly over the height of the supply air chamber extends, and that at least one measuring device is arranged in the end region of the channel, with which the fresh air volume flowing through can be determined.
- the invention is based on the idea that the distribution of the fresh air to be fed into the processing cabin is now not, as in the known prior art, via vertically arranged air distribution pipes or channels in the for
- Air supply chamber of fresh air is sufficient Measuring section made available without increasing the overall height.
- the predetermined length of the forced guidance of the fresh air is advantageously determined in such a way that an essentially constant speed profile of the air flow can form in the forced guidance, so that the exact determination of the fresh air volume passing through the cross section of the forced guidance or of the duct is made possible.
- the parameters necessary for calculating the exact air flow volume are determined at the end of the forced guidance of the fresh air supplied by suitable measuring devices and then the passage opening is changed to a predetermined value in accordance with the calculated controlled variable .
- the amount of fresh air supplied and thus the rate of descent can be automatically and exactly maintained for one or more sections in the treatment booth, by precisely determining the inflowing amount of fresh air and, for example, by changing flaps in the area of the respective associated one Through openings are arranged, the flow cross section is changed so that a predetermined value for the inflowing amount of fresh air is always maintained.
- the air supply chamber is divided into individual sections by partition walls and the fresh air supplied to the supply air chamber is viewed in the inflow direction next to each other or one after the other, divided into different partial air flows and in each case forcibly guided over a suitable length parallel to the ceiling and only then flow into the individual sections of the air supply chamber through associated passage openings. This ensures that the fresh air volume can be exactly determined for each section of the air supply chamber and can be set independently of one another by regulating the associated passage openings to a predetermined value.
- predetermined values can be set for each section of the air supply chamber or the underlying sections of the treatment booth, such as air sinking speed, air volume supply, air humidity and air temperature or the like can be defined exactly in the desired manner independently of one another.
- a duct connected to the passage opening extends over a predetermined length parallel to the ceiling and the inlet opening of the duct, through which the fresh air introduced into the supply air chamber flows into the duct, is partially or entirely over the
- the entire height and width of the supply air chamber extends at least one control flap at the end region of the duct arranged parallel to the ceiling, as seen in the direction of flow of the fresh air, so that the volume of fresh air flowing through the cross section of the duct is constantly adjusted to the fresh air volume flowing into the air supply chamber based on the control variable measured by the measuring device set a predetermined value.
- the inflowing fresh air volume can be regulated exactly for the sections of the treatment cabin underneath, for example by the adjustable flaps in the area in front of the respective passage openings
- Dependence on the individually measured air flow volumes are set automatically so that the predetermined value for the respectively assigned section in the treatment booth or the sections in the air supply chamber is always maintained.
- an air humidification and / or heating device is assigned in each of the channels, as a result of which, for each individual section in the treatment cabin or for each section of the divided air supply chamber, the air sink rate, the fresh air volume supplied and whose moisture content and / or its temperature can be set independently of one another with optimal use of the overall height.
- the air volume for each section can be achieved by the measuring devices arranged at the end can be determined exactly and - as already mentioned - the associated passage opening or openings can be changed in such a way, for example, by adjustable flaps, so that the value once specified can be adhered to exactly for each section in the treatment cabin below.
- the air supply chamber is divided by partition walls that form an angle of less than 90 ° with the direction of flow of the fresh air in the supply air chamber, the fresh air in the individual sections of the divided air supply chamber is deflected evenly approximately parallel to the ceiling and only then flows through at a constant rate of descent the air-permeable ceiling in the treatment cabin.
- the partitions are advantageously in the air supply chamber and the end walls directed towards the through opening at the end of the parallel channels in the supply air chamber are arranged parallel to one another, so that the air flow is deflected evenly.
- the supply air quantity can be set very precisely over the entire cabin area by entering the desired air quantity or the air sinking speed as a default and the volume measuring device with the individual measuring devices in connection with a control device for each control flap accordingly set to the required value.
- this specification can be entered, checked and documented when using a recording device. The accuracy of the setting options increases with an increasing number of sections per cabin area.
- the economic outlay for finishing work is reduced and the rate of workpieces which are properly coated in the first painting process is increased.
- the device according to the invention and the method according to the invention can be used both for wet painting and for powder coating booths.
- Fig. 1 shows a longitudinal section through an inventive
- Paint booth in a schematic representation, which is equipped with a number of series-connected channels arranged parallel to the cabin ceiling for the supply of fresh air, and
- an air supply chamber 2 which is divided into different sections by inclined partition walls 8, is arranged above an air-permeable ceiling 1.
- a supply air chamber 3 runs above the air supply chamber 2 and is separated from the air supply chamber 2 by an intermediate ceiling 31.
- the supply air chamber 3 is connected to a fresh air supply system, not shown, which ensures the supply of fresh air into the supply air chamber 3.
- the intermediate ceiling 31 has a number of through openings 4 located one behind the other in the flow direction of the fresh air introduced into the supply air chamber 3, as a result of which the supply air chamber 3 is connected to individual sections of the air supply chamber 2.
- Air supply chamber 2 are formed by the partitions 8 connected to the ceiling 1 and the intermediate ceiling 31; advantageously, as in this embodiment the dividing walls 8 are each connected to the front edge of a passage opening 4 and then run inclined in the flow direction up to the ceiling 1.
- adjustable flaps 5 are each rotatably fastened, as a result of which the flow cross section towards the passage opening 4 or the passage opening 4 itself is controllably changeable, ie the flow rate of the fresh air into the individual sections of the air supply chamber 2 can be regulated.
- a paint mist separator and suction device 10 are arranged below the cabin or the application area.
- a plurality of channels 6 running parallel to the ceiling 1 are arranged one behind the other in the flow direction in the supply air chamber 3, so that their respective inlet openings 7 are perpendicular to the inflow of fresh air from the fresh air supply system connected to the supply air chamber 3.
- the respective inlet openings 7 extend in their height and width over part of the cross section through the supply air chamber 3, so that in each case part of the fresh air supplied flows into a channel 6 and a further part above and / or next to it can flow further into the channels 6 behind .
- a channel 6 is simply formed by the intermediate ceiling 31 and a wall, which is arranged parallel to it and is spaced apart from it and extends over the entire width of the supply air chamber 3.
- heating and / or humidifying devices are provided at the beginning of each channel 6, so that the air can be humidified or warmed in the desired manner individually for the individual sections of the treatment booth or the individual sections in the air supply chamber 2. Then at the end of the channel 6, the incoming fresh air volume is precisely determined by the measuring devices and the flap 5 in each passage opening 4 is adjusted by a suitable drive such as an electric motor so that a predetermined value for the incoming air volume is exactly maintained.
- the individual air channels extend over a portion of the height of the supply air chamber 3, so that only a portion of the incoming fresh air volume is branched off into the supply air chamber 3 into the individual sections of the air supply chamber 2.
- the partial air flow is then brought individually for each section of the treatment cabin to the intended temperature, the desired air humidity content and also the amount of fresh air to be supplied.
