Definitions
- the invention relates to a device for generating vibrations, with a base on which a support device is held by means of a resilient connection and can oscillate relative to the base, wherein the support device is connected to a drive device and driven by this oscillating, and with a holding device, which is coupled via elongated spring elements with the support device and can swing relative to the support device.
- WO 2011/083148 A1 is a drive device for a
- Membrane filtration device known in which a membrane package is suspended in a frame vibrationally.
- the frame stands with rubber-elastic vibration elements on a base plate and is provided at the level of the membrane package with a vibration drive, which includes a motor with imbalance.
- the membrane pack is connected to the frame via horizontally oriented springs.
- the lateral dimensions of the membrane package are limited by the frame.
- the height of the frame must be matched to the height of the membrane package.
- the object of the present invention is to provide a device for generating vibrations, wherein the device does not limit the design of the width of the objects to be picked up (and to be vibrated) from the outset.
- the device according to the invention has the features of claim 1.
- the holding device is arranged above the support device, and that the spring elements extend in an upright direction between the holding device and the support device.
- the holding device absorbs the object to be vibrated or the device to be vibrated. Due to the arrangement of the holding device above the carrying device, the carrying device does not limit the space above the holding device.
- the device is significantly more flexible than the known device with regard to the height and width of the objects to be picked up.
- the object to be vibrated relatively wide ie relatively large in the horizontal direction, and relatively small in the vertical direction. The ease of use can be improved.
- the carrying device and holding device oscillate essentially in horizontal planes.
- the resonant frequency of the holding device (and the objects located thereon) is used, so that the highest possible oscillation amplitude is achieved with the lowest possible expenditure of energy.
- the holding device oscillates in a linear, translatory or rotational manner. Also combinations are possible, such as a linear oscillation in one direction and a torsional vibration in another direction. By the spring elements and torsional forces can be transmitted. By rotational movement of the support device - triggered by the drive device - may lead to a torsional vibration of the holding device relative to the support device.
- the carrying device can be driven in a swinging manner about a central axis by the drive device. The support device then oscillates about the central axis and can transmit this vibration to the holding device.
- the holding device oscillates about a central axis.
- the vibration of the supporting device is transferred to the holding device in such a way that the latter vibrates about the central axis.
- the vibration path of the holding device is preferably at least about +/- 7mm (total 14mm) at a distance of 250mm to the central axis.
- the holding device is supported by the spring elements.
- the holding device When the drive device is stationary, the holding device rests on the upright spring elements or, in operation, the holding device rests on the spring elements.

- the spring elements are upright and are connected at one end to the support device and at the other end to the holding device, in particular clamped in this.
- the ends are fixed and non-hinged to the support device and holding device.
- the ends are nevertheless preferably solvable.
- the ends can be inserted into matching recesses in the holding device and supporting device and fixed there. This simplifies the overall construction.
- retaining elements may be provided for clamping the ends.
- the spring elements are not yielding in their longitudinal direction, so that the length remains constant. Upon bending of the spring elements, this results in a slightly variable distance between the support device and the holding device, with a maximum distance with elongated spring elements and a smaller distance with bent spring elements. As a result, in addition to the described oscillation, the holding device can be excited to a vertically directed vertical oscillation.
- the spring elements are bars or plates, which are preferably flexible in one direction yielding elastic.
- it is elongated plates, round or flat rods.
- the spring elements are bending elements. "Bend-elastic in one direction" means that the spring elements can swing back and forth substantially in one plane, but can perform no or non-functionally relevant movements in a plane aligned transversely thereto. As a result, the direction of movement of the vibrations can be influenced by targeted arrangement of the spring elements.
- the spring elements form the function of a central torsion spring. That is, a plurality of spring elements cooperate and allow a torsional vibration of the holding device.
- the spring elements for simulating the function of a torsion spring are arranged as upright bending elements along a circle.
- the spring elements in the circumferential direction or tangential to the circumferential direction of the circle are flexurally elastic and relatively rigid in the radial direction.
- the holding device oscillates substantially in the horizontal direction in the circumferential direction back and forth. Since the spring elements can have a clear distance to the center of the circle, results in a much more stable arrangement together with the attachments or structures on the plate than in a single torsion bar.
- a plurality of groups of spring elements may be provided, for example, successive groups in the circumferential direction.
- a plurality of spring elements are preferably arranged next to one another in the radial direction.

- the vibration of the support device relative to the base may be damped by the bearings, such as visco-elastic bearings, pneumatic bearings or coil springs.
- Drive device, support device, spring elements, holding device with male object or overlying device are coordinated so that the holding device oscillates with the object held thereon or the device with its resonance oscillation.
- the drive device is an unbalance motor, in particular with an upright axis of rotation.
- a forming plane of rotation then runs horizontally, in particular parallel to the vibration plane of the support device or in the same.
- the term "unbalance motor” is to be understood in the broadest sense. It is preferably a rotating machine with an eccentric counterweight. Alternatively, however, a linear or translational reciprocating drive can be provided, which generates a swinging movement of the T jagvorraum.
- the drive device is connected away from a central axis with the carrying device.
- the drive device is in particular connected to an edge of the carrying device, flanged to the edge or screwed to the edge.
- a further drive device or a counterweight are provided on the carrying device, opposite the drive device, in particular on the edge of the carrying device.

- support device and holding device are connected to each other via tension members.
- the traction elements act only in the upright direction, while transversely to no or only lower forces are transmitted.
- the task of the tension members is primarily to secure a maximum distance between the support device and the holding device to each other.
- the holding device has a receptacle for connection to objects to be vibrated, in particular for connection to a housing for a membrane packet.
- the membrane packet should be held securely on or on the holding device and swing together with the holding device.
- the receptacle is provided in particular on the upper side or underside on the holding device. But it can also be provided on both sides recordings on the holding device.
- a downwardly directed axis can be held on the holding device on the underside, for connection to objects to be vibrated, in particular for connection to a screening device.
- support means and optionally also the base are provided with openings for passing the axle. That's the way it is possible to hold an object to be vibrated below the base.
- the axis may be formed as a tube, in particular for sucking liquid from a lower sieve device, such as a sieve basket in a tank.
- the tube is torsionally stiff to perform the vibration of the holding device with.
- the sieve device stays longer for the liquid. Dirt particles do not accumulate as quickly as a static sieve.
- the invention also provides a device for filtering liquids, in particular for ultrafiltration, nanofiltration and / or reverse osmosis, with a device as described above, and either with a membrane packet connected to the holding device or with a lower sieve device.
- the membrane packet preferably has horizontal membrane planes.
- the device should be provided for filtering solids from liquids, such as waste water from agriculture or industry or in drinking water treatment.
