Definitions
- the invention relates to a flip-flop screening machine with cross members carrying the screen linings, which are positioned between
- Sieving machine side walls are arranged and of which at least every second cross member as a driven cross member vibrations and / or
- Flip-flow screening machines (DE 35 21 753 C2, EP 978 327 B1) can be divided into two groups: Forcibly driven flip-flow screening machines and unbalance-driven flip-flow screening machines.
- the movement In the case of the positively driven screening machines, the movement is usually positively forced by an eccentric shaft.
- the side walls of both systems carry out counter-rotating linear movements in the longitudinal axis.
- Unbalance-driven flip-wave screening machines are set in circular or linear vibrations by unbalance waves.
- An additional coupled mass-spring system oscillates with a greater amplitude, so that there is a relative movement between the systems, which can be used to tension the screen linings.
- the object of the invention is to improve an unbalanced fluted corrugated screening machine of the type mentioned at the outset so that it is easier to use
- the cross members attached to a side wall are made alternately rigid and movable.
- the movable cross members are not only used for
- This design causes the cross members to vibrate directly without any excitation via a large unbalance drive and the moving side walls.
- FIG. 1 is a perspective view of a flip-flop screening machine with two driven and three non-driven cross members without showing the screen linings / screen mats,
- Fig. 2 is an axial section through an unbalanced tubular motor between the
- Fig. 4 three different large screening machine modules.
- a flip-flop screening machine 1 has two parallel vertical machine side walls 2, 3, between which cross members 4a, 4b carrying screen linings, in particular screen mats, are mounted, the preferably horizontal longitudinal axes of which are perpendicular to the side walls.
- every second cross member 4a performs a circular or linear movement in particular vibration, whereas those in between
- Crossbeams 4b are not driven, so that during operation the distances between the crossbeams 4a, 4b are alternately larger and smaller and the screen linings attached between the crossbeams, in particular screen mats, are stretched and compressed so that the screen openings do not clog.
- each driven cross member 4a has its own separate drive, which is located within the cross member.
- all driven cross members each have an oscillation and / or vibration drive between the machine side walls over their own separate majority of their length or over their entire length.
- each driven cross member has an outer tubular casing 5 extending along the cross member, in the interior of which a drive generating the oscillations and / or vibrations, in particular an electric unbalance motor 6, is arranged, with a shaft 7, an eccentric 8, shaft bearing 9, lateral rubber elements 10 and lateral flange plates 12.
- the pipe casing 5 extends between the two side walls 2, 3 of the screening machine.
- the coupling to the side wall takes place either as a rigid element or by means of a flexible rubber coupling.
- each driven cross member has an unbalanced tubular motor or a vibrating tubular motor in its interior.
- the unbalanced tubular motor has a motor shaft 7 which is parallel to the longitudinal axis of the cross member and on which a
- the unbalance body is arranged as an eccentric 8 which extends over a large part of the cross member length.
- the unbalanced mass is integrated into the motor shaft due to the geometrical shape of the motor shaft and generates an unbalance / centrifugal force during operation.
- the driven cross members each have the oscillations or vibrations at their two ends generating electric motor, on whose single motor shaft located between the motors the unbalanced body / eccentric 8 is arranged.
- the unbalance body of a cross member extends over the space between the two motors of the cross member.
- cross members are spring-loaded
- Couplings connected to the side walls of the screening machine, so that additional circular / elliptical and / or linear vibrations are transmitted to the screen linings or to the screen linings and the machine side walls.
- the tensioning screening machine preferably has a modular design, the modules being coupled to form double or multi-deck machines.
- the modules each have two screening machine side walls, between which at least one driven and one non-driven cross member extends.
- the advantage here is that the screen machine side walls have a constant height over their length.
- longitudinal members with front and rear walls are used instead of the cross members and side walls, the
- transverse or longitudinal beams Carry out longitudinal beam vibrations across the direction of the sieve and material flow.
- the transverse or longitudinal beams can also execute different movements, in particular in opposite directions, due to operation that is not in phase. It is also advantageous if the transverse and / or longitudinal members with
- Vibration forms are set which influence the transport behavior of the material being screened on the machine.
