Description

Collecting device for overspray, filter module and

Method for constructing a filter module

The invention relates to a collecting device for overspray, which has a liquid ^¬ keitsdichtes material.

The invention also relates to a filter module for separating overspray with a filter housing and with a catcher for overspray.

Furthermore, the invention relates to a method for constructing a filter module for a surface treatment system, wherein the filter module is provided with a collecting ^¬ device for overspray. In the manual or automatic application of paints on objects in a paint booth, a partial flow of the paint, which generally contains both solid and / or binder and solvent, not applied to the Ge ^¬ genstand. This partial flow is referred to in the art as Overspray ^¬ net. In the following, the terms overspray, overspray particles or overspray solids in the sense of a disperse system, such as an emulsion or Sus ^¬ pension or a combination thereof understood. The overspray is detected by the air flow in the spray booth and fed to a separation.

Basically, separation systems are known, which work with separation units, which are designed as exchangeable filter modules with at least one filter unit and with a filter housing. Such filter modules are replaced after reaching a limit loading with overspray and then disposed of or possibly recycled. The use of such filter modules can be energetic and in terms of the required resources of advantage.

Such filter modules are supplied with the cabin air laden with overspray, which flows through the filter modules and exits exhaust air largely freed from overspray. Hereinafter, also such exhaust air for the sake of simplicity is referred to as cabin air or as exempt from overspray cabin air. From DE 10 2013 004 082 A1 a separator is known, in the overspray particles in a flow-through of cabin air filter module abge ^¬ eliminated. The filter module described here has a lower collection area, which is liquid-tight and thus formed as a collection tray for overspray, which is deposited in the filter module, flowing down in this, and accumulates in the sump to a paint sump.

DE 10 201 1 108 631 A1 also describes a separating device which operates with filter modules through which cabin air laden with overspray can be conducted and in which overspray separates, in which case at least one lower collecting region of the filter modules is liquid-tight and in this way ^{sam ¬} melwanne is designed for overspray.

In order to form such a collecting trough for overspray, DE 10 201 1 108 631 A1 proposes injecting sealing compound into the bottom region of the filter housing and distributing it uniformly in the bottom region by means of a tumbling table. Furthermore, an alternative collection trough is shown in DE 10 201 1 108 631 A1, in which a peripheral trough frame is provided, the z. B. can be made of thin wooden boards, wherein in the Tannenrah- men a liquid-tight receiving bag is inserted, in which the filter housing can be placed, and the upper edge is slipped outwards over the tub frame.

Object of the present invention is to provide a comparison with the prior art improved collection and storage container for overspray.

This object is achieved by a device of the aforementioned type, wherein the material of the collecting device is a multilayer composite material having at least one liquid-tight layer, said layer and / or at least one further layer of the composite material resistant to overspray ^¬ formed, wherein the collecting device is formed into a usable state by folding from an initial state in which the collecting device is in a flat shape, wherein the collecting device in the state of use forms a trough. Such a collecting device can be easily transported and kept ready and can be set up ready for use within a short time and with little effort. At the same time a high density and reliability of the tray formed by the collecting device is ensured. For example, in order to further simplify the production of the collecting device, the collecting device may have one or more folding lines for the folding. This can also reduce the risk of the occurrence of errors in the structure. It may be expedient if the collecting device in the state of use at least substantially has the geometry of a cuboid and forms an upwardly open pan with a bottom and side walls. This form is particularly suitable when using the collecting device for a replaceable filter module of a surface treatment plant.

In an advantageous embodiment of the collecting device, the trough may have one or more sections, which are formed glued overlapping.

A technically favorable solution is given if at least one adhesive bead is provided to close the side walls and / or the bottom of the trough.

It may be advantageous if the at least one liquid-tight layer of the composite material is present only in one or more subsections of the collecting device.

The collecting device can preferably have a plurality of fastening ^elements .

Advantageously, the fasteners may be at least partially formed by at least one continuous layer of the composite material.

Furthermore, it may be expedient if one or more fastening elements are adhesively bonded to the trough on at least one side wall of the trough. - -

In order to increase the functionality and possible uses of the collecting device, the collecting device may have one or more cutouts for receiving at least one further component. The object of the invention is also achieved by a filter module for Abschei ^¬ the overspray, with a filter housing and with a collecting device for overspray, wherein the collecting device is formed according to the invention or one of its embodiments. Such a filter module can be constructed with little time and effort. At the same time, a particularly reliable and reliable collection of overspray is ensured.

It may be expedient for the folded collecting device to surround at least one bottom region of the filter housing. Preferably, the folded collecting device can be connected by means of laterally arranged fastening elements with the filter housing.

Advantageously, the filter housing can be formed by the folded collecting device. For example, a particularly simple and compact design of the filter module can be made possible.

To raised stabili ^¬ hen example, the stability and manageability of the filter module, the folded collecting device may be disposed on a bottom part and is connected thereto.

In an advantageous development, the folded collecting device can be connected to the bottom part by means of laterally arranged fastening elements.

The object of the invention is also achieved by a method of the type mentioned, in which a collecting device, which is designed according to the invention or one of its embodiments, starting from its initial state is folded so that it forms a pan for catching over ^¬ spray , The advantages of the method are analogous to the pre ^¬ share the filter module of the invention. It may be advantageous if the catcher is provided stacked for construction in a flat form.

In an alternative embodiment, the collecting device for the structure can be provided wound as a roll le.

Furthermore, it may be advantageous if a collecting device is withdrawn from a roll and cut to provide them in their initial state for the construction of the filter module.

Further advantageous embodiments of the invention will become apparent from the following description. Here, embodiments of the invention, without being limited thereto, explained in more detail with reference to the drawing. In a simplified, schematic representation:

FIG. 14 with a bottom part;

Fig. 1 shows a front view of a portion of a Oberflächenbehand ^¬ treatment plant with a treatment cabin, which may be for example a coating cabin for articles. In Fig. 1, a painting booth 2 is shown as an example of such a coating booth, in which vehicle body ^¬ rien 4 are painted. It is possible for the vehicle bodies 4 to have previously been cleaned and degreased, for example, in pretreatment stations not specifically shown, which may be located upstream of the paint booth 2. The La ^¬ ckierkabine 2 rests according to the example shown in a conventional manner and on a steel structure. 6

In an upper region of the painting booth 2 is a paint tunnel 8, which is bounded by side walls 10 and a cabin ceiling 12. The paint tunnel 8 is open at the bottom in such a way that cabin exhaust air laden with overspray can flow downwards out of the paint tunnel 8. The cabin ceiling 12 is formed as a filter cover and forms the lower boundary of an air supply space fourteenth

Above a lower opening 18 of the painting tunnel 8, a steel frame 20 is arranged, which carries a known per se conveyor 22, which will not be discussed here. With the help of the conveyor 22 to be painted vehicle bodies 4 can be moved through the paint tunnel 8. Inside the painting tunnel 8 are application devices, for example in the form of multi-axis application robots 24, by means of which the vehicle bodies 4 can be coated with lacquer.

The lower opening 18 of the painting 8 is abge ^¬ covered by a grid 26 below which a contact area 28 is located, in which the entrained air from the cabin overspray particles separated from the cabin air. Thus, air flows down from the air supply space 14 through the paint tunnel 8 to the system area 28, wherein the air in the paint tunnel 8 absorbs paint overspray and carries the overspray with it out of the paint tunnel 8.

The plant area 28 comprises a flow area 30 into which the cabin air laden with overspray first flows and which, for this purpose, is open towards the paint booth 2 upwards. In the flow region 30, the cabin air first passes into a guide channel 36 of an air guiding device 38, which is formed by guide plates 40. The guide channel 36 opens into one or more connection channels 42, which lead the cabin air into a separation region 44 of the system region 28. In the separation zone 44, the connecting channels 42 are fluidly coupled to a filter module 48, for example through the intermediary of a discharge port 46, that the cabin air into the can flow in one or more modules Filtermo ^¬ 48th A filter module 48 can be configured as Abschei ^¬ Defilter or inertial filter or as a combination thereof, in and of itself known manner. Preferably, each filter module 48 forms one of several Abscheideein ^¬ units, with which a modular trap device 52 operates, which is arranged in the separation region 44 of the spray booth 2. Fig. 2 shows an example of the configuration of a filter module 48. It can be seen in the drawing, that the filter module 48 has a filter housing 56 with a filter inlet 58 and a filter outlet 60, wherein the filter ^¬ housing 56 shown has a rectangular cross-section , The filter inlet 58 is bounded by an upper inlet region 56e of the filter housing 56 while the filter outlet 60 is provided in a housing wall 56b. The housing walls 56a, 56b, 56c and 56d form the side walls of the filter module 48.

In the example shown, a passage depression 62 is formed on the housing wall 56b at the upper inlet region 56e of the housing 56. Due to the Through passage 62 is formed at the inlet portion 56e of the housing 56 on three sides of a collar 64 which projects with respect to the passage lowering 62 upwards. In the present embodiments, the filter outlet 60 includes two outlet windows 60a and 60b superimposed in the operating orientation of the filter module 48.

The cabin air laden with overspray flows through the filter inlet 58 into the filter module 48, is deflected in the filter module 48, flows through a filter unit 48 arranged inside the filter unit 66, the details of which are not shown here and on which the overspray separates, and leaves the filter module 48 through the filter outlet 60 as largely exempt from overspray cabin air.

Preferably, a bottom part 68 may be provided for the filter module 48, wel ^¬ ches as in the present embodiment, at least substantially in its geometry and its dimensions as a standardized support structure and, for example, according to the specification of a so-called Euro-pallet is formed. A Euro pallet has an extension with side lengths of 800 mm x 1200 mm.

FIG. 1 illustrates, by way of example, that a filter module 48, when using such a bottom part 68, can be moved with a conveyor system 70 adapted to such standard structures. In the exemplary embodiment shown here, such a conveyor system 70 comprises, for example, a conveyor truck 72 that can be manually operated by a worker 54, for example.

According to the example shown in FIG. 1, the exhaust air, which is now largely freed from overspray, flows out of the filter outlet 60 of the filter module 48 through a docking unit 74 with a branch channel 78 into a collecting channel 76. The exhaust air can, via the collecting channel 76, possibly be further conditioned and conditioned are fed and subsequently passed in a not shown here ^¬ ge circuit again in the air supply chamber 14, from which it flows again from above into the paint tunnel 8. - -

The louver 38, the one or more filter modules 48 of the separator 52, the one or more branch channels 78 and the collection channel 76 thus define a cabin air flow system in which the filter modules 48 each form an exchangeable section. Even if individual filter modules are 48 away from the flow system Strö ^¬ tion system as such remains operational.

The filter modules 48 formed as replaceable units can be supplied to the ge ^¬ called flow system and thereby moved in a feeding movement in the operating position or are separated from the operating position of the flow system and moved away.

The movement of the filter modules 48 can take place at least in sections with the aid of the conveyor 70. To move a filter module 48 relative to the docking unit 74 toward or away from it, a bottom guide 80 may be provided. In the example shown in Fig. 1 embodiment, this Bo ^¬ denführung 80 is formed as a roller conveyor 82, and therefore part of the conveyor system 70. A component, a plurality of components or all the components of the filter module 48 shown as an example in Fig. 2, for example, from materials ge ^¬ manufactures be , such as As cellulose-based materials such as optionally behan ^¬ delte paper and / or cardboard materials, corrugated cardboard, cartons with standing Wel ^¬ le, honeycomb cartons, wrapping cartons, and / or other materials such as MDF materials. The filter module 48 itself can be delivered in günsti ^¬ ger configuration as a modular kit in pieces and assembled on site.

The overspray which separates during operation of the separation device 52 in a filter module 48 flows at least partially downwards within the filter ^housing 56 and accumulates in a bottom region 56f of the filter ^housing 56. The accumulated in the bottom portion 56f of the filter housing 56 Over ^¬ spray can form a paint sump there. - -

Fig. 3 shows an example of a catcher 90 for overspray, which is in an initial state and is in the form of a flat shape. The collecting device 90 shown in the example is ausgebil ^¬ det as a flat panel.

The collecting device 90 consists of a multi-layer composite material, preferably a hybrid material, the more layers may preferably below ^¬ schiedliche properties. The collecting device 90 shown by way of example has on its upper side a plurality of fastening elements, which are designed in the form of tabs 84. Before ^¬ Preferably, these flaps may be integrally formed together with the actual collection device 90 84th In the example shown, the layer structure of the composite material in the area of the tabs 84 corresponds to the layer structure in other areas of the catching device 90. For better clarity, such tabs are shown in FIGS. 4A to 4E, 6, 11, 12 , Figs. 13A and 13B and Fig. 15 are not provided with reference numerals.

In order to provide the collecting device 90 in its initial state, it can be produced, for example, as a flat shape by punching. Preferably, the collecting device 90 can be punched together with the fastening elements. It is also possible the collecting device 90 in its initial state, possibly together with the fasteners to produce by cutting. The collecting device 90 shown by way of example has an upper portion 90d and a lower portion 90c. To assist in folding the catcher 90, it may be provided with stamping lines 92a, 92b. Shown in the example are a horizontally arranged stamping line 92a, which runs between the upper subarea 90d and the lower subarea 90c, and a plurality of vertically arranged stamping lines 92b. The stamping lines 92b may assist in folding the catcher 90 when the catcher 90 is converted to a use condition (see FIG. 5) by folding from the initial condition shown in FIG. - -

Is illustrated in FIG. 4A and FIG. 4B, it is initially recommended that the Auffangvor ^¬ direction 90 along the vertical crease lines 92b to fold so that the folded edges 94 are formed. A possible procedure for folding the collecting device 90 is initially to move the two lateral end regions 90a of the collecting device 90 towards one another, for example by folding the two lateral end regions 90a, as indicated by the arrows 100 in FIG. 3 and in FIG. 4A.

In a modification not specifically shown, the catcher 90 may also be prefabricated as a ring closed in the direction of rotation, so that this step, in which lateral end areas are moved toward one another, is eliminated. For example, the collecting device can also be ^{ausgebil ¬} det as a tube section. According to the intermediate state shown in Fig. 4B, the catcher 90 has six fold edges 94 and forms a laterally closed hexagonal shape which is open upwards and downwards. The end portions 90a be ^¬ stir thereby located in a lateral portion 96 of the collecting device 90. Preferably, the end portions 90a mitei- by means of an adhesive bond Nander, wherein z. B. in the side portion 96, a bead can be applied. It is also possible for the end regions 90a to be glued overlappingly together in the region of the lateral section 96 and / or otherwise sealed. In the course of the collecting device 90 along the horizontal score line 92a is folded on the one hand, as is ^¬ indicated in Fig. 4C by means of the arrows 101, the lower portion is folded 90c of the collecting device 90 down and also, as shown in Fig. 4D is indicated by means of arrows 102, part ^¬ portions of the lower portion are moved 90c of the catcher 90 outwardly such that two opposing triangular flaps are formed 88, which project beyond the side walls 106 of the shape of the collecting device 90 shown. The material forming the catcher 90 is folded in two layers in the region of the triangular flaps 88. - -

For better clarity not provided with reference numerals end portions of the lower portion 90c of the catcher 90 touch, such. As can be seen in Fig. 4D, in a lower portion 98 of the catcher 90. Preferably, these end portions are connected to each other by means of an adhesive bond, wherein z. B. in the lower portion 98, a bead can be introduced ^¬ . It is also possible for these end regions to be glued together overlappingly in the region of the lower section 98 and / or otherwise sealed. In the further course, as indicated in FIG. 4E with the aid of the arrows 103, the two triangular tabs 88 are folded under a bottom 108 of the shown shape of the catching device 90, so that the catching device 90 finally becomes in its use state (see FIG. 5). located. Fig. 5 shows the folded catcher 90 in its use state. The collecting device 90 forms a trough with a closed bottom 108 and closed side walls 106. This basic form of closed-bottomed tub 108 and closed sidewalls 106 is already given in the intermediate states shown in FIGS. 4D and 4E. According to the example shown, the folded triangular tabs 88 are in the use state of the catcher 90 under the bottom 108th

FIG. 7 shows a filter module 48, which is received by the collecting device 90. The collecting device 90 is shown here in the form of a trough, which has been folded, for example, as described above. The tub is arranged as a collecting container for overspray in the lower region of the housing 56 of the filter module 48. The side walls 106 and the bottom 108 (see FIG. 6) of the tub enclose the bottom portion 58f (see FIG. 2) of the filter module 48 at least up to a certain height. - -

As illustrated in FIG. 7, the side walls 106 of the tub have fastening ^elements on their upper side, which may be designed, for example, as tabs 84. These tabs 84 may be used to attach the trough to the filter housing 56 and may be glued thereto, for example. Since tabs 84 are located at a height where they are not expected to be exposed to liquid or overspray, tabs 84 may alternatively or additionally be riveted or stapled to filter housing 56, for example.

According to the example shown in Fig. 7, the trough is located on a bottom portion 68. In this case, the bottom 108 (see Fig. 6) of the tub with the bottom part 68 may be ver ^¬ glued and / or z. B. by means of the triangular tabs 88 (see FIG. 6) may be attached to the bottom part 68.

Fig. 8 differs from Fig. 7 in that lateral fastening elements are provided in a lower portion of the tub, which are formed in gezeig ^¬ th sample as holding elements 1 10 and may preferably be bonded to the side walls 106 of the tub. These holding elements 110 are used for fastening the trough, which is formed by the catching device 90, to the bottom part 68. The holding elements 110 can be glued, riveted and / or stapled to the bottom part 68, for example.

In the examples shown in FIGS. 7 and 8, the folded collecting device 90 forms a collecting trough which receives the housing of the filter module 48.

Fig. 9 shows a filter module 48 with a filter housing 56 and with a bottom ^¬ part 68. In the interior of the filter housing 56 is in the example shown, a filter inlet 66 ^¬ integrated recognizable. According to the exemplary embodiment shown here, the folded collecting device 90 forms the housing of the filter module 48. The fil ^¬ ter housing 56 shown is produced by folding the collecting device 90, wherein the collecting device 90 from an initial state (see FIG. 10) in the Ge ^{¬ used} state is transferred according to FIG. 9. - -

One or more arranged inside the filter module 48 components, eg. B. the indicated in Fig. 9 filter unit 66, by means of the cutouts 1 12 of the collecting device 90, which also forms the filter housing 56, are held. In the example shown, the cutouts 1 12 for holding the filter unit 66 of the filter module 48 are arranged in the side walls 106 of the catching device 90 and penetrate them.

Fig. 10 shows the catcher 90, which is shown in Fig. 9 in use as part of the filter module 49, in its initial state. The collecting device shown is provided with cutouts 1 12 in the form of openings which can receive components in a state of use, for example, components which are arranged in the interior of the filter module 48 (see FIG. 9). In the illustrated case ^¬ play the cutouts are constructed as slot-like openings 1 12, which penetrate the material of the collecting device 90th The cutouts 1 12 can be made together with the catcher 90, z. B. by punching or cutting, or even be attached later. The number, position and shape of the one or more cutouts 1 12 can be adapted to the use of the catching device 90 if necessary. The cutouts 1 12 can be mounted on site or even before a transport.

The collecting device 90 according to the example shown in Fig. 10 embodiment includes a horizontally disposed crease line 92a and a plurality of vertically angeord ^¬ designated embossing lines 92b. The folding of this collection device 90 shown by way of example from its shape in the initial state (see FIG. 10) to its shape in the use state (see FIG. B. analogous to the folding, which has been described for ^¬ before for another embodiment of a collecting device 90 in connection with Fig. 3, Fig. 4A to 4E and Fig. 5.

FIGS. 9 and 10 show a collecting device 90 which is provided with a filter outlet 60 and with a through-passage depression 62, wherein the filter outlet 60 has, for example, two outlet windows 60a and 60b. The collecting device 90 preferably has ^¬ already in its initial state to a Derar ^¬ term expedient embodiment to be used in their folded state of use as the filter housing 56 to be able to. - -

Fig. 1 1 shows an example of a multi-layered flat-folded collecting device 90, as z. B. may be formed in a transport state. The collecting device 90 shown here corresponds to the embodiment of the collecting device 90 already described in connection with FIG. 3. In the example shown, the collecting device 90 is folded into a plate with a first layer 141 and with a second layer 142. The transport state shown is characterized by compactness and good handling. The Auffangvorrich ^¬ tion shown can be performed in an advantageous training at three edges tightly connected.

As illustrated in Figure 12, the containment devices 90 may be stacked for storage and / or transportation. The exemplary gezeig ^¬ th in Fig.12 collecting devices 90 for this purpose have the convolution shown in FIG. 1 1, wherein also otherwise flat folded collecting devices 90 and in principle also lent unfolded collecting devices 90, z. B. catching devices 90 in their initial state (see FIG. 3), can be stacked.

Alternatively, with appropriate material quality on ^¬ catch devices 90 for storage and / or can be rolled up for transport. When storing and / or transporting the catching devices 90 in a roll shape, a plurality of catching devices 90 can form a material strip. If necessary, individual catching devices 90 can then optionally be withdrawn from a roll and cut off by cutting. In FIGS. 13A and 13B, as well as in FIG. 14, there is shown a catcher 90 which is similar in construction and functionality to the catcher 90 already described in connection with FIGS. 3, 4A-4E, and 5 has been. In this case, the intermediate state shown in FIG. 13A corresponds to the intermediate state according to FIG. 4B and the intermediate state shown in FIG. 13B corresponds to the intermediate state according to FIG. 4C.

In the case of the collecting device 90 shown in FIG. 13A, a plurality of cuts 16 in the material of the collecting device 90 can be seen in a lower partial region 90c. These incisions 1 16 are arranged directly adjacent to the upper portion 90 d of the collecting device 90. In the example shown are - -

the incisions 1 16 below the horizontally arranged embossing line 92a arranged ^¬ , wherein an incision 1 16 defines a planar area in each case together with a portion of the pre ^¬ gel line 92a. The cuts 16 cut through only one or more outer layers of the composite material of the catcher 90, wherein at least one inner layer of the composite material is not cut. If, starting from the intermediate state shown in FIG. 13A, the lower part region 90c of the catching device 90 is folded inwards, ie moved in the direction of the arrow 101 in the example shown, then they come loose in the region of the cuts the one or more cut outer layers of the composite material from the at least one uncut lower layer of the composite material. In this way, the one-piece connected to the rest of the collecting device 90 mounting tabs 1 14 can be formed, as they are already visible in Fig. 13B and finally in use (see Fig. 14) of the catcher 90 are present.

Analogous to the procedure described above with reference to FIGS. 13A and 13B, one or more similar or different types of tabs can also be attached to the catching device 90. The fold line used to form such flaps can be arranged as the pre ^¬ gelinie 92a exemplarily shown in Fig. 13A in a different region of the collecting device 90. Fig. 14 shows the catcher 90 in use with lateral fasteners on its top and on its underside. In this case, the fastening elements 1 14 formed as fastening elements, which have been prepared, for example, as described in connection with FIGS. 13A and 13B, arranged on the underside of the trough, which is formed by the collecting device 90. Further formed as tabs 84 fasteners are disposed at the top of this tub.

FIG. 15 shows the collecting device 90 according to FIG. 14 with a bottom part 68, which may be designed, for example, according to a so-called Euro pallet. In the illustrated embodiment, the catcher 90 rests on the - -
