Die erfindungsgemäße Vorrichtung zur Reinigung einer Pulverbeschichtungskabine weist eine erste Luftblasleiste (9) auf, die am Boden (4) der Pulverbeschichtungskabine (1) angeordnet ist. Zudem sind eine zweite Luftblasleiste (13), die an einer Seite (3) der Pulverbeschichtungskabine (1) angeordnet ist, und ein Absaugkanal (7), der einen Absaugschlitz (7.1) aufweist, um überschüssiges Pulver abzusaugen, vorgesehen. Die erste und die zweite Luftblasleiste (9, 13) sind vorgesehen, um überschüssiges Pulver in Richtung des Absaugschlitzes (7.1) zu blasen.
摘要:
First divided booths 2 and 3 are moved to coating positions P to form a coating booth and an article to be coated carried by a carrying device is coated in the coating booth. Second divided booths 5 and 6 are retracted to cleaning positions C and cleaning booths 8 and 9 are moved from retracted positions T to operating positions S5 and S6 to cover the openings of the divided booths 5 and 6, and then cleaning is performed in this state. After the cleaning is completed, the cleaning booths 8 and 9 are returned to the retracted positions T, and the second divided booths 5 and 6 are moved to the coating positions P to form a second coating booth. After the coating by the first divided booths 2 and 3 is completed, the first divided booths 2 and 3 are retracted from the coating positions P to the cleaning positions C, the cleaning booths 8 and 9 are moved from the retracted positions T to the operating positions S2 and S3, and the cleaning is performed to ready for a next color change.
摘要:
Powder overspray that is extracted from a spray booth is recovered back to a powder supply that is used to supply powder to the spray guns inside the spray booth. The powder overspray extracted from the booth is separated from the high flow air stream by a separator such as a cyclone separator. The powder falls into a transfer pan and a vacuum is used to convey the powder from the transfer pan to a vacuum receiver. The powder is then discharged to the feed hopper in the feed center. The use of a vacuum to convey powder from the cyclone to the feed center in effect permits substantially all of the powder overspray to be recovered from the spray booth directly to the feed hopper with minimal dwell or residence time within the cyclone or vacuum receiver subsystems during a spraying operation. The receiver can be rotated for easy cleaning, and the vacuum line cleaned by one or more cleaning elements drawn through the vacuum line.
摘要:
A powder coating system is provided comprising a powder spray booth (2) with a powder recovery system having an overspray intake (18) communicating with the interior of the booth. A diverter plate (26) may be held within the booth (2) to define with the booth floor (10), a duct leading to an overspray intake (18) of the powder recovery system. Alternatively or additionally, the coating system may include an air assist which provides jets of air across a portion of the interior surface of the booth. The surface may be one or more sloped portions (22) of the floor. The air supply may be pulsed to produce periodic bursts of air across the interior surface.

A spray coating booth (1) has a column-shaped design with a lid (4), a substantially flat bottom (2) and a cleaning device (15; 15'; 15''; 15''', 15'''') which can move in the vertical direction of the booth for automatically cleaning up at least the inner wall surfaces of the booth. The booth (1) may if required have door-shaped flaps (8) for pre- and post-coating areas (44, 45) and if required a closable slot for inserting spray coating devices (43). The spray coating booth (1) has a bottom (2) that can be opened and the cleaning device (15; 15'; 15''; 15'''; 15'''') is arranged at least partially below the bottom (2) in the standby position. The bottom (2) may be designed as a subdivided bottom (20, 21) or may be removable as a whole, or it may be designed as a swivelling bottom (40, 40'). More advantageously, the space below the bottom (2) in which the cleaning device (15; 15'; 15''; 15'''; 15'''') is kept in the standby position is designed as a closed cleaning chamber (29, 29'), and so the cleaning device (15; 15'; 15''; 15'''; 15'''') may be automatically cleaned up after the inside o f the booth has been cleaned. Also disclosed are corresponding designs and arrangements of the vertical displacement means (17; 17'; 17''; 17'''; 17'''') for the cleaning device (15; 15'; 15''; 15'''; 15'''').
摘要:
Von den Oberflächen einer Pulversprühbeschichtungskabine werden Beschichtungspulverpartikel abgesaugt (8, 9, 14). In der Luft auf der zu reinigenden Oberfläche (1) werden mittels einer Hochspannungs-Ionisiervorrichtung (20) Ionen erzeugt, welche von Pulverpartikeln und der zu reinigenden Oberfläche (1), wenn sie ein anderes elektrisches Ladungspotential haben, elektrisch angezogen werden. Damit werden die Pulverpartikel elektrisch neutralisiert und die Anziehung zwischen den Pulverpartikeln und der zu reinigenden Oberfläche (1) wird eliminiert. Dadurch können mehr Pulverpartikel von einem Saugluftstrom (14) auf der zu reinigenden Oberfläche (1) erfaßt und abgesaugt werden.
摘要:
A spraying device, in particular for spray-painting objects (4), has a conveyor (1) for transporting the objects and a collector (5) for collecting the medium sprayed past the objects and the conveyor. The collector has an endless circulating belt (5) independent from the conveyor (1) and a device (7, 8) which rests on the belt (5) for removing the medium sprayed thereon.
摘要:
Cabine (11) de revêtement d'objets par projection de matériau pulvérulent, du type dans laquelle les objets sont assujettis à traverser un espace de projection défini par un plafond (15), des parois (17) et un plancher (24), ladite cabine comportant des moyens d'évacuation (30) du matériau pulvérulent déposé dans ladite cabine vers des trémies (31) de récupération, caractérisée en ce qu'elle comprend au moins une barre de raclage (40,50) susceptible d'être montée contre ledit plafond ou au moins l'une desdites parois. Chaque barre (40,50) est couplé magnétiquement avec son système d'entraînement (43,53). Le procédé consiste à nettoyer par raclage le plafond (15) et les parois (17) avant de nettoyer le plancher (24) en installant au moins une barre de raclage (40,50) amovible.
