Definitions

  • the invention relates to a tumbler screening machine with a stationary Underframe and a sieve structure supported by the underframe.
  • tumble screening machines There are numerous tumble screening machines have become known from the literature, see for example DE 33 43 615, DE 42 36 349, DE 299 01 833 U1.
  • the sieve structure makes a wobbling movement during operation. It embraces a floor pan, one or more sieve inserts, a corresponding one Number of intermediate cylinders between two adjacent ones Sieve inserts and a hood. The number of sieve inserts and the Intermediate cylinder depends on the fractions that you use with such Machine wants to achieve.
  • the sieve inserts comprise sieves in a known manner with different mesh sizes.
  • the vibrating part has a modular structure.
  • the items must be Purposes of inspection, cleaning or changing the screen from time to time be dismantled.
  • the disassembly is that the individual parts connecting tie rod solved and the individual parts of the vibrating sieve structure can be lifted by hand.
  • the vibrating part has the Switch off the machine from case to case in a different position within the levels mentioned.
  • the hitch is in one and the same place, with respect to the vertical axis of the stationary base covered. This means the following: if a Lift off the vibrating part after a certain period of time is intended, the vibrating part must be repeated by hand again and again be aligned with the hitch.
  • the invention has for its object a tumble screening machine specify which avoids these disadvantages.
  • the tumbler screening machine according to the invention has a Lifting device on the vibrating part of the machine if necessary is dockable.
  • the lifting device is therefore not always with vibrating part of the machine firmly connected, but is only when necessary attached to this vibrating part, that is when maintenance repair or exchange work, of course in the Standstill.
  • the main lifting device is a pneumatic or hydraulic unit into consideration, but also an electromotive unit.
  • lifting devices for example one telescopic unit. It is also possible to arrange the arrangement in this way the screen decks are selectively lifted off. For example, has one Tumbler five screen decks, so the three lower ones in their Normal position remain, and only the top two are lifted off.
  • the invention achieves the following in detail: Since the lifting device is normally not attached to the vibrating part, that is to say during operation, the above-mentioned problem of increasing the flywheel mass does not occur at all. It follows that the individual components of the machine do not have to be reinforced.
  • Another advantage is that the lifting device with a plurality of Tumbler screening machines can be used. In other words: for multiple tumbler screens only need a single lifting device to stand by.
  • the lifting device can also be used on existing machines without them Change can be docked.
  • the docking points are the ones Fastening points of the existing tie rods.
  • the tumbler screening machine shown in FIG. 1 has a rigid base frame 1 on and one carried by it and vibrating during operation Sieve structure 2.
  • the base frame includes a base 1.1, a motor 1.2 and rubber rods 1.3, on the one hand on the base 1.1 and on the other hand on Attack sieve assembly 2.
  • the screen structure 2 comprises a floor pan 2.1, a first screen insert 2.2, an intermediate cylinder 2.3, another sieve insert 2.4, and so on, and finally a hood 2.5.
  • a lifting device 3 is provided. This is in Normal state - that is, during the operation of the tumbler screening machine - removed from the machine.
  • the lifting device 3 comprises a lifting cylinder 3.1 as essential components and a lifting rod 3.2.
  • a holder 4 is provided. This is on the one hand attached to the tub floor 2.1, on the other hand to the lifting cylinder 3.1.
  • the holder 4 comprises a socket 4.1 through which the Lift rod 3.2 is passed.
  • the lifting rod 3.2 is at its upper end with a tab 5.1 Pin 5.2 fixed to the hood 2.5 - mind you, only if the Lifting device 3 is needed. Usually, that is during the Operation of the machine, are the connections between Lifting rod 3.2 on the one hand as well as bracket 4 and bracket 5.1 with plug pins 5.2 solved.
  • Each swivel device comprises a clamp which the lifting rod 3.2 encloses, also a swivel arm, for example the swivel arm 6.1.1 of swivel device 6.1 and a set screw 6.1.2 for fixing the Swivel device in a certain angular position.
  • the pivoting device 6.1 is pivoted such that it is on the intermediate cylinder 2.3 attacks. If the lifting rod 3.2 is extended from the lifting cylinder 3.1, this leads to entrainment of intermediate cylinder 2.3 and all of it stationary components of the sieve structure up to the hood 2.5.
  • the wobble screening machine shown in FIG. 2 is constructed in principle in the same way as that shown in FIG. 1.
  • the distances between the individual swivel devices 6.1 to 6.4 are of different sizes - see dimensions a 1 to a 3 .
  • This has the following effect: if, for example, the lower swivel device 6.1 engages the lower intermediate cylinder 2.3, the swivel devices 6.2, 6.3 and 6.4 above it are also raised, but initially do not yet attack the modules located above them. This is due to the fact that the distances between the upper edge of the individual pivoting device and the lower edge of the subsequent sieve insert increase from bottom to top. See the dimensions b1, b2, b3, b4.
  • the lifting devices are diagonal to each other to be arranged opposite, so that the corresponding sieve insert after two sides between the lifting rods can be pulled out. How one see, the individual lifting devices can also be used on any other Dock the circumference of the tie rods depending on the position of the outlets or other structural conditions. The expansion direction of the Sieve inserts can therefore be freely selected as required.
  • the lifting cylinder 3.1 is on the floor pan 2.1 docked.
  • the lifting cylinder with clamps 3.1.2, 3.1.3 provided by means of screws on the floor pan quickly and easily or screwed to a corresponding tab can.
  • a swivel device 6.1 can be seen, which acts on a module.
  • the Swivel device 6.1 rests on a cross pin 3.2.1, which extends when extending the lifting rod 3.2, the swivel device 6.1 and therefore also that associated module. See arrow A.
