Embodiment Construction

[0056] exist Figures 1 to 7 The device shown in , denoted as a whole by 100 , comprises a purely schematically shown conveying device 104 for painting a motor vehicle body 102 , by means of which the motor vehicle body 102 can be conveyed along a conveying direction 106 The movement passes through the painting area 108 of the spray booth indicated as a whole by 110 .

[0057] The painting area 108 is the interior of a paint spray booth 110 which is delimited by a chamber wall 114 towards both sides of the conveying device 104 in a horizontal transverse direction 112 extending perpendicularly to the conveying direction 106 corresponding to The longitudinal direction of the spray booth 110 .

[0058] Arranged in the paint booth 110 facing both sides of the conveying device 104 is a painting device 116 , for example in the form of a painting robot.

[0059] By means of a (only partly shown) circulating air circuit, an airflow is generated which passes substantially vertically ...

Abstract

The invention relates to an apparatus for separating wet paint overspray from a stream of untreated gas containing overspray particles, comprising at least two filter devices which respectively comprise an inlet opening, through which a partial stream of the untreated gas enters the filter device concerned, and in each case at least one filter element for separating the overspray from the partial stream of untreated gas. To provide such an apparatus which makes it possible to maintain the flowability of the mixture of filter-aiding material and wet-paint overspray, cleaned off from the filter elements, easily and efficiently in the containers for receiving filter-aiding material, it is proposed that the apparatus comprises at least one receiving container for receiving a material cleaned off from filter elements of a number of filter devices and a mixing device for mechanically mixing the cleaned-off material from a number of filter devices.

Description

technical field [0001] The invention relates to a device for separating wet paint overspray from an untreated air stream containing overspray particles, the device comprising at least two filter devices, each of which comprises an air inlet, respectively The treated air flow enters the associated filter devices via the air inlet, and these filter devices each comprise at least one filter element for separating the overspray from the partly untreated air flow. Background technique [0002] After first adding a flowable, granular filter auxiliary material called "Precoat" material to the untreated air stream, in this device, from the corresponding untreated Dry separation of wet paint overspray in process air. [0003] The auxiliary filter material is used as a barrier layer to be deposited on the surfaces of the filter elements in order to prevent these surfaces from being bound by adherent overspray particles. By periodically cleaning the filter elements, the mixture of au...
