Definitions
- the present invention relates to a screening device according to the preamble of patent claim 1.
- EP 1 454 679 A1 discloses a sieve-controlled screening machine with two frame-shaped oscillating bodies, each having transverse rigidities connected to the longitudinal frames, in which the second oscillating body is arranged within the first oscillating body.
- the first oscillating body is driven by a directly coupled to this drive unit, while the second oscillating body forcibly guided by an eccentric shaft of the first oscillating body, via an elastic
- Coupling element connected thereto and is elastically vibration coupled along at least two coupling axes. 1 Accordingly, the second oscillating body reaches larger as a spring-mass system
- the elastic screen coverings are each between the cross members of the first and the
- Clamped cross members of the second oscillating body so that they move during the screening process between a stretched and compressed position back and forth.
- a screening machine with a screen surface which comprises only a frame in which the cross members are alternately rigidly and resiliently mounted.
- the Siebbelagsetti are each attached to the rigid and the spring-mounted cross members.
- the frame is in turn driven swinging, so that the Siebbelags institute also alternately undergo an upsetting and stretching phase due to the different vibration behavior of the rigid and spring-mounted cross member.
- EP 0 218 575 A2 shows a screening device in which the elastic sieve elements are mounted on cross beams which are movably supported in two opposite directions, in a plane perpendicular to their longitudinal axes, and provided at both ends with a drive which sets them in motion ,
- the object of the present invention is to improve a screening device of the type mentioned by the structural design is simplified and increased variability is achieved. This object is achieved by a screening device with the features of

- an embodiment of the invention provides that the spring elements are arranged on the outside of the frame. This means that the attachment of the spring elements takes place outside of the screen space.
- the spring elements are removably attached to the frame.
- the second cross member also in the frame or screen box can be introduced, fastened, removed and / or interchangeable and / or connectable to the spring elements.
- Spring elements are received in the openings of the frame and have a connection point for the second cross member, which are located inside the screen box or frame. Because all the components of the second
- Movement system can be replaced very quickly from the outside of the screening device, the screening devices of the invention Extremely service-friendly, as longer downtimes for maintenance
- Another advantage in the interchangeability of the spring elements is that different operating parameters with respect to the vibration characteristic, in particular the resonance frequency, vibration amplitude and acceleration values are caused by different spring elements. Since with different geometries or dimensions of the screening device a vote of the overall system must be made, this can be easily achieved by changing and replacing the spring elements without having to make further structural changes to the frame or screen box.
- the vibration behavior of the second cross member is significantly influenced by the expression of the spring elements.
- An embodiment of the invention also provides that the openings are sealed dust-tight in the frame by the spring elements. This ensures that the environment around the screening device can be sealed against the screening room.
- the spring elements may essentially comprise a rigid connection element and an elastomer permanently connected thereto.
- This elastomer may be provided, for example, cylindrical, annular or in the form of a hollow profile.

- the spring element which may also be referred to as a damping element, preferably comprises a vulcanized between two coupling elements made of metal rubber element.
- two coupling elements made of metal rubber element are provided as a rigid connection elements coupling elements made of metal, which enter into a solid, in particular shear-resistant connection with the rubber after vulcanization of the rubber mixture.
- an embodiment of the invention provides that the elastomer or rubber element has a circumferential groove.
- This circumferential groove can in turn have a conical cross-sectional shape, wherein the groove is arranged on the screen material facing side of the elastomer.
- the groove with the inclined side walls accordingly causes screenings, which reaches into the region of the spring elements, can not settle, but is automatically transported out of the opening again by the design of the elastomer and the movement of the vibrating device.
- An advantageous embodiment of the invention also provides that the elastomer comprises a sealing lip.
- This integrally formed sealing lip serves to close the opening in the frame or in the side cheek of the screening device again dust-tight.
- the vibration behavior of the second Cross member is adjustable relative to the first cross members and the frame on the hardness of the elastomer. Furthermore, the oscillation behavior of the second cross member can be controlled via the spring characteristic of the spring element, in particular via the ratio of the spring characteristics in the vertical and horizontal directions of the spring element.
- FIG. 1 shows a screening device with a frame with first rigidly mounted cross members as the first oscillating mass in a perspective view.
- Figure 2 is a number of second cross members to be mounted as a single carrier and second oscillating mass in the frame of Figure 1.
- Fig. 3 is a perspective view of the overall vibration system of first and second oscillating mass with the resiliently mounted in the frame second

- Fig. 7 shows a section through the spring element of Fig. 6 along the line VII-VII.
- Fig. 1 shows a screening device according to the invention with a first
- the sieve device is a device with two sieve planes or two sieve trays arranged one above the other.
- the first oscillating mass comprises a frame 1 with two side cheeks 2, between which a number of first cross members 3 are arranged rigidly and parallel to each other.
- the side walls 2 thus form with the first Cross beams 3 a rigid box body, the so-called sieve box on which the drives or exciter (not shown) for generating the
- Swinging motion can be fixed.
- the frame 1 is mounted on supports 81, 82, which have different lengths, resulting in an inclined arrangement for the frame 1 and the plane of the sieve.

- FIG. 3 shows that the first cross member 3 and the second cross member 4 are arranged alternately in the frame 1 or swing box.
- Sieve-excited sieve devices are frequently used for screenings which have a high moisture content. With vibrating screens with rigid screen coverings, screenings with a high degree of moisture pose the risk that the screenings close the screen openings and the screening process is not efficient enough. Therefore, for sieved screen devices, elastic screen coverings (not shown) are used, which are alternately stretched and compressed during the screening process, so as to cause a vertical acceleration of the screenings. As a result, the closing or clogging of the screen openings is considerably reduced.
- the screen coverings are fastened with one side to a first cross member 3 and with the other side to a second cross member 4.

- the elastomer 51 is connected both via its inner jacket and over its outer jacket, each with a connection element. In addition to the coupling function, it also has a sealing function.
- Fig. 5 shows a perspective view of the spring element 5 of the frame 1 and the screen space facing side.
- Connection element comprises a first connection plate 52, with which the
- Spring element 5 rests against the side wall 2 of the frame 1.
- the first rigid connecting element comprises two angled flanges 521, via which the spring element 5 is bolted to arranged on the outside of the frame 1 stiffening angles 7.
- a second rigid connection element with a second connection plate 54 is provided in the middle of the spring element 5 and serves for fastening the second cross member 4.
- the second connection plate 54 has a number of boreholes 541, which are used for screwing the spring elements 5 on at the end sides of second cross member 4 arranged end plates are used.
- Both the first connection plate 52 and the second connection plate 54 are fixedly connected to the elastomer 51 via a respective coupling element 53, 56.
