Description

Modular take-off device Field of the invention

The present invention relates to a modular extraction device, in particular for laboratory areas.

background

Discharge devices, especially for laboratories, have been known for a long time from the state of the art; these are dealt with in particular in the standard DIN EN 14175 (compare sections 1 - 7 there). Deduction devices are designed to provide a safe workplace environment for scientists, engineers and medical professionals working in dangerous / hazardous materials laboratories.

Usually deduction devices to existing

Venting units connected to suck air from an enclosed by the exhaust device interior. In addition, exhaust devices are provided with different ports, for example, to lead liquid and / or gaseous media to or in the trigger device. Known trigger devices are often more than 500 kg heavy and usually have a height of more than 2.7 m. According to the standard DIN EN 14175

Deduction devices doing a possibility of intervention (for example, by a vertically displaceable front window) with a

Minimum opening height of 1.8 m, this being

Intervention possibility in turn must be completely closed.

Deduction devices from the prior art are usually made of heavy plates (in particular chipboard), spent in individual parts to the appropriate locations and built there more or less one-time stationary. For construction and Connection of such exhaust device are usually required about ten hours of assembly on site. Typically, craftsmen of various disciplines, such as a carpenter, an electrician, an installer and a service technician, are needed to set up and connect known extraction devices. Here are the

Extractors usually in parts to the

Installation site supplied so that not only the assembly of known trigger devices is complex, but also their transport.

During use of the fume cupboard, these are operated either via controls (e.g., switches, sockets, fittings, media ducts, etc.) attached to the fume cupboard, or via controls provided beneath a tabletop on which the fume cupboard has been mounted. In this case, intermediate walls are often provided, in which the

Controls are arranged. This results in a juxtaposed arrangement of two exhaust devices between a relatively wide structure with four walls. Accordingly, such an arrangement of two or more exhaust device next to each other requires a correspondingly large footprint.

If, on the other hand, the operating elements are provided below a table on which the take-off device is often arranged, then both in the lower region of the take-off device and also at the upper part of the take-off device are usually corresponding

Installations arranged. Such installations make it difficult in particular the transport and installation of one of

Trigger mechanism.

In recent years, the work in laboratories has changed a lot, in particular, there are now a number of relatively short-term projects that make it necessary

Laboratory workstations quickly build up and dismantle, with a modification should be able to quickly. In addition, it will be on Modern exhaust devices worked both standing and sitting. In the light of these requirements, in the state of

Developed technology modular devices, which are disclosed for example in the publications US 5,487,768 A and DE 295 00 607 Ui. US Pat. No. 5,487,768 A relates to an isolator which is intended to enable work under clean room conditions. On the other hand, DE 295 00 607 Ui relates to a table deduction device which can be viewed and operated from several sides. However, the table top device does not include any fittings or other connections and is otherwise specially designed for use in schools or other

Designed training centers.

Based on this prior art, the present invention has the object to provide a modular extraction device that can be assembled and disassembled relatively quickly and, moreover, can also be easily modified. In particular, the present invention has the object, a modular extraction device

to provide a simple conversion or retrofitting of supply and discharge for process media. Furthermore, a

Deduction device are given, which has the largest possible interior space compared to their outer dimensions, in

Lightweight construction is provided, with further modular

Deduction devices is easy to combine and can be provided in numerous dimensions.

These and other objects, which will become apparent upon reading the following description or which will be recognized by those skilled in the art, are achieved by the subject-matter of the independent claims. The dependent claims further form the central idea of the present invention in a particularly advantageous manner.

Detailed description of the invention

A modular extraction device according to the invention, in particular for laboratory areas, comprises a (inner) space enclosing Housing with side walls and a ceiling wall, wherein at least one of the side walls comprises a window slider, wherein the walls comprise profile elements, between the plate elements are detachably arranged, and wherein at least one side wall is formed such that a further take-off device can be arranged thereon that a from the two drawers enclosed (interior) space results.

In other words, the present invention proposes, the walls of a take-off device according to the invention by means of

Profile elements, in particular by means of hollow profile elements (in particular with the aid of hollow aluminum profiles), the holding means (e.g., clamping connections, clip connections, etc.) for holding the arranged between the profile elements

Include plate elements.

The plate elements can be provided from glass, chip or sheet metal plates. The plate elements are thereby releasably arranged on the profile elements in order to easily allow a modular arrangement of at least two extraction devices, i. in an arrangement of at least two exhaust devices that located between the two exhaust devices

Plate element or the two plate elements are removed, so that there is a space enclosed by two exhaust devices.

The use of glass or transparent plates is thereby particularly preferred since this does not result in an "optical" division of the space, but rather an overall space which remains uniform in the overall impression, as is desired, in particular, in open-plan laboratories

Suction device used as a workplace for laboratories, the plate elements must also meet other requirements. When using chemically aggressive / corrosive substances in the extraction device, the plate elements must be correspondingly resistant to chemicals. When using combustible materials should the plate elements basically not or be difficult to burn and not splinter in a possible deflagration. In many experiments, it is also advantageous if the plates are transparent. In other experiments, intervention openings or cable bushings are advantageous.

In general, it is advantageous if the plate elements are formed as light as possible in order to keep the weight of the entire structure as low as possible. The plate elements of the extraction device should therefore not be considered constructive or structural components of the

Discharge device to be formed. For this reason, it is advantageous that the plate elements are easily interchangeable in operation, so that the plate elements or the extraction device to the respective

Operating situation can be adjusted or can. Incidentally, this will make repairs by replacing the

Simplified plate elements. Depending on the application or

In the operating situation, the plate elements can therefore be made of single or multi-pane safety glass, transparent or opaque plastic plates, aluminum or steel plates, multi-component or multilayer materials and / or ceramic plates.

Preferably, the extraction takes place completely or in the process

Essentially completely over the ceiling wall, so no

Suction plates or suction channels are needed.

In addition, more than two extraction devices can be arranged side by side or in succession, with corresponding intermediate plate elements can be removed, so that there is a correspondingly large enclosed space. Alternatively, there is also the possibility of releasable

Plate elements between two adjacent extraction devices not to remove, so that there is an overall arrangement with several enclosed spaces. Preferably, a multi-part profile arrangement is provided on at least one side wall in order to form at least one vertical channel, which is adapted to receive the operating elements of the

Deduction device is used. In this case, a multi-part profile arrangement is preferably provided on the right, left or both front sides of the trigger device.

The multi-part profile arrangement preferably comprises an outboard L-shaped profile and an internal hollow profile, which can be connected to corresponding cross-sections to form a channel. Depending on requirements, the transverse profiles can have different widths (for example 50, 100 or 150 mm), so that different widths, vertical channels can be provided depending on the application. The multi-part profile arrangement is preferably made available from aluminum profiles, for example by means of

Clamps, clips or can be connected to each other by means of screw.

In practice, vertical ducts with a width of approximately 50 mm are used, provided that no installations (for example, supply or discharge lines for media, fittings, valves, sockets, switches,

Securing devices, etc.) are provided in the vertical channels.

Vertical channels with a width of about 100 mm are used in practice, as far as controls in the vertical channel

to be included, with vertical channels with a width of about 150 mm for receiving larger mounting elements, such as fuse boxes, are used.

For example, if two draw-off devices are connected to each other, profile arrangements with a width of only 50 mm can be used in the connection area, so that a (in comparison to an arrangement with two independent draw-off devices) space-saving, inexpensive and simple construction of such a combined trigger system results.

The vertical channels, which are provided from multi-part profile arrangements and receive the operating elements, can thereby in a particularly advantageous manner as preassembled preforms

be provided so that they can be easily replaced on the one hand during operation or a mounting of such a modular extraction device done very time-saving

kann.Vorteilhafterweise a separate Vorstück is provided for each control. As a result, in each case the operating element can be easily replaced together with the profile element.

In the front region of the vertical channel can be done attachment of the controls, with sufficient space for appropriate cable and / or in the rear region of the channel

Wiring is available.

Preferably, the cables and lines in the vertical channel are guided upwards, so that they protrude from the top of the channel and can be connected there to corresponding terminals.

Advantageously, the lines and cables are equipped with standardized plugs or quick-release couplings, so that a modular extraction device according to the invention can also be constructed quickly in this regard and provided with the necessary supply. Further, in the vertical channels as well

Operating elements for the at least one window slider,

corresponding control devices and / or power supplies are arranged for the at least one window slider.

In addition, a fan arrangement can be provided in the upper area of the at least one vertical channel in order to be able to provide an air flow. In addition, vents can be provided in the vertical channel, which lead into the interior to for example, with the help of the arranged in the upper area

Fan arrangement to blow out air from the interior of the exhaust device, for example, to improve the air flow in the interior of the trigger device.

The incoming air prevents turbulence and

Return flows, which can otherwise form, in particular behind the vertical post elements.

As already noted, the multi-part profile arrangement is modular in such a way that the width of a vertical channel formed thereby can be easily changed, in particular by the

Cross profiles are exchanged, in practice, in particular the following widths of the cross profiles / channels are used:

a transverse profile width of 150 mm in order to be able to accommodate larger installations (for example a security device);

- a width of 100 mm, around fittings (e.g.

Sockets, etc.) to be able to record;

- a width of 50 mm, as far as a vertical channel no or only small installations must accommodate;

- A double post with a width of 50 mm to order

in particular to connect two extraction devices and as far as no or only small fixtures are to be included in the vertical channel;

- A double post with a width of 150 or 200 mm, so as to connect in particular two exhaust devices and as far as correspondingly large installations are to be included in the vertical channel.

The widths mentioned are common widths in practice, although other widths and combinations, depending on the application, are possible. In a particularly preferred embodiment, two vertical channels are formed by multi-part profile arrangements, which are preferably provided on a front side of a modular extraction device (ie left and right at the front, the

preferably also comprises the at least one window slider).

The vertical channels are preferably about 1.7 m long.

Typically, the trigger is placed on a table placed / fixed, which has approximately a height of 0.9 m, so that thus results in an installation height of the two vertical channels between a height of 0.9 to about 2.6 m. Advantageously, the

Itself a height of less than 2.0 m, so that when mounted on such a table frame, a

Total height between 2.5 and 2.8 preferably gives about 2.6 m.

Between the vertical channels in this case correspondingly adapted horizontal profile elements (preferably at least two per

Side wall) so that a stable sheet frame member can be provided by the profile members between which plate members (e.g., a glass sheet, chipboard and / or sheet metal plates, etc.) can be arranged to thereby form a corresponding wall of the extractor.

Preferably, the vertical channels are connected to at least two horizontally extending profile elements. The rear wall (i.e., one of the side walls) is preferably formed from at least four profile elements (preferably two horizontal and two vertically arranged profile elements), wherein in turn at least one plate element between the formed by the profile elements flat frame element (releasably) is arranged.

Advantageously, the at least one window slider (which is preferably provided in the front wall) by means of a

moved electrical device, these preferably in Ceiling area (in particular above the window slider) is arranged.

Usually, known extraction devices have a

Window slider arrangement, which are up to 30 kilograms, since the window gate valves are usually stabilized with corresponding counterweights. By operating the window slider by means of an electrical device, it is possible to dispense on the one hand heavy counterweights for the window slider and also on the usual stop means, as appropriate

Stop points can be provided by the electrical device.

Preferably, the window slider by means of a rope or

suspended belt so that the cable or the belt can be rolled up on a roll when raising the window slider. Preferably, the window slider is connected to two

Slices held by means of appropriate ropes and rollers, the rollers preferably by means of a stabilizing crossbar

connected to each other.

The extraction device preferably has at least two

Side panels open window. There is the possibility that two people can work in the interior at the same time.

Preferably, on the ceiling wall, a suction device

arranged, wherein the ceiling wall is formed largely as a perforated ceiling plate to allow air flow through the ceiling wall.

Preferably, the ceiling wall is formed in two parts, a rear portion of the ceiling wall is designed as a perforated plate, above which there is a Abluftverteilkammer, with a

corresponding venting system is connected. This space above the perforated plate serves to equalize the pressure to a even flow through the holes / perforations of the

Ceiling plate to allow. Preferably takes place above the

Exhaust air distribution chamber (in particular on the upper wall) of the connection to the ventilation system, wherein in this area beyond an exhaust air control device (for example in the form of a controllable

Flap arrangement) can be provided. The front portion of the ceiling wall is preferably designed as a transparent plate, which seals the trigger upwards against the room and above which a lighting device is arranged.

The extraction device advantageously has no baffles or other conventional air handling devices (e.g.

Nozzle devices) on the side walls, so that the only extraction advantageously takes place via the perforated ceiling plate. Advantageously, the ceiling slab is formed to a large extent as a perforated plate, so that there is a substantially in the entire cross section of the extraction device to the side walls parallel air flow (quasi as a kind

Piston flow). Such a parallel to the side walls extending air flow in this case has the particular advantage that the entire cross-sectional area of a suction device can be kept safe from pollutants, and it is irrelevant how many window sliders of the trigger device are open. As already noted, this can be done on the usual

Double wall constructions are dispensed by means of corresponding baffles, which are often provided in the region of the rear wall and in which an extraction of the air takes place via this baffle. In contrast, in the presently proposed arrangement of the suction device, each side wall with a corresponding

Window slider can be equipped (ie also the rear wall can be formed with a transparent plate member, so that the interior is also visible from the rear wall forth). This also makes it possible to provide this otherwise used as a rear wall side wall for connection to another exhaust device. In addition, the mean residence time of the pollutants in the interior is shortened by such a flow guide, compared to the usual cylindrical air flow guides.

Advantageously, the plate elements of all the side walls are made of transparent plates (for example made of safety glass or a corresponding plastic compound). This makes it possible to view the extraction device from all sides, it being possible to work from all sides in the interior of the extraction device by means of corresponding access openings (for example, further window slides or corresponding engagement devices).

Furthermore, it is preferred that at least gripping devices are provided on the extraction device, thereby carrying the

To facilitate extraction devices. The gripping areas can be provided for example by means of extendable rods or by means of appropriate handles.

Advantageously, the extraction device (in particular the lower region of the extraction device) is adapted to be mounted on a table or pedestal. This can be done, for example, by means of appropriate connection possibilities (e.g.

Screw connections), for example, to the multipart

Profile arrangements are provided.

Advantageously, connections, in particular electrical and / or mechanical above the ceiling wall are provided, which are preferably designed as plug-in connections.

Furthermore, it is advantageous if at least one media channel is provided in at least one side wall. Such media and removal channels include screwed aluminum profiles that can be arranged in the side walls. These channels usually have a removable front cover in which sockets and / or fittings can be provided. such

Additional channels facilitate the operation of larger units, such channels can also be used later. In this case, only the plate elements must be removed, adjusted accordingly and used together with the intervene can be re-used channels in the frame element.

The media channels can be provided both horizontally and vertically in the existing side walls. Preferably, the media channels are doing in the already existing

Profile elements or installed in the existing profile arrangements. If necessary, this can also be new

Profile elements or profile arrangements are provided.

The controls of the trigger device are preferably arranged in the multi-part profile assemblies on the front sides. It is also possible to install units for the automatic / remote-controlled removal of media or sockets in the media channels. In this way, larger units can be safely accessed and operated.

Advantageously, the extraction device is designed in such a way (i.e. in particular the individual lengths of the profile elements and the

Plate elements) that they can be arranged and transported in disassembled state on a Euro pallet.

With the present modular extraction device according to the invention, the following (main) assemblies can preferably be formed:

- A front part, comprising the multi-part mullions arrangements, for example, two vertical channels, a window slider with electric drive unit and corresponding pulleys, a lamp arranged in the upper region, an upper window and corresponding maintenance flaps, and arranged in the vertical channels controls; Advantageously, the front part is preassembled and has dimensions of about 1.5 m x 1.5 mx, 0.25 m (in order to be able to provide a draw-off device with a typical width of approx. 1.5 m);

- A ceiling unit with an exhaust device, comprising

corresponding connections and controller units;

- disassembled side walls, optional substructures, table racks and table tops.

The modular extraction device can thus be easily transported and mounted, it being particularly preferred that the above-mentioned parts or assemblies are dimensioned such that they can be transported on a Euro pallet. Due to the comparatively low height of the take-off device, a loaded with corresponding components of the trigger device

Europallet be transported well through conventional doors and in usual lifts. After the respective assemblies are not particularly difficult, these can optionally also be constructed by only one fitter.

During assembly, the trigger device with a

Lifting device (such as a cable) lifted so that a table placed or four feet can be arranged on the trigger device. Subsequently, the trigger device can be lowered and leveled accordingly. After connection to the technical supply facilities, optional installations can be provided.

During disassembly, the optional substructure is first removed, the corresponding supply connections dismantled, the upper part or the trigger devices raised and the feet or the

Table frame dismantled.

In addition, due to the modular design of the

Discharge device the possibility during laboratory operation to install further side channels and / or media channels, more To arrange controls in the vertical channels, more

Deduction devices to be mounted on existing exhaust devices etc.

A take-off device is provided with typical widths in practice between 1.2 and 2.4 m, and preferably in 0.3 m "jumps", ie in widths of 1.2 m, 1.5 m, 1.8 m, 2.1 m and 2.4 m, due to the modular design, other widths or dimensions can be easily provided by, for example, the profile elements or the plate elements are adapted or selected accordingly.
