Definitions

  • the bulk material passes through the conveyor line several times to Reaching the predefinable or desired degree of mixing.
  • Vibratory conveyors are known from the prior art, so far however, it was only used as a pure sponsor. With these The vibrating channel is promoted by rapid vibrations moving up and down with small amplitude, the back and forth movements being about the same amount of time to have. Through this ideally sinusoidal swinging motion the bulk particles experience a forward movement that from a throwing phase and a contact phase with the conveyor put together. In the contact phase, the material to be conveyed becomes transfer required speed. In the throwing phase due to its inertia, it continues to fly while the vibrating trough swings back in their starting position. Through the repeated periodic oscillating trough movement results in an essentially continuous, fluid movement of the conveyed goods.
  • the bulk material in view the conveyor line to take up as little space as possible selected helically, the bulk material preferably is promoted upwards.
  • a Mixing device with a bulk feed and a bulk discharge used in between the bulk feed and a vibratory conveyor is arranged in the bulk material discharge, in whose conveyor line protrudes at least one deflector who a part, preferably about half of the subsidized and separates premixed bulk material.
  • a portion of the bulk material is provided with which the separated bulk material returned to the beginning of the conveyor becomes.
  • the vibratory conveyor is preferably included as a spiral conveyor a conveyor trough formed in the at selected locations Conveyor section partially protrudes through which a Fraction of the bulk material branched off and only the remaining one Share is carried on.
  • the spiral conveyor can also have several Have conveyor troughs or as a double or multiple helix with several parallel spiral conveyor tracks be coupled with the single vibration exciter if necessary are.
  • the branched fraction arrives via a drop room the beginning of the conveyor.
  • the spiral conveyor used for mixing has the advantage of being staggered Deflectors, each part of the conveyor line cover, one and the same drop space for the branched off Bulk material is used that in the upward promotion operated vibratory conveyor falls due to gravity, so that no additional conveyor drive for the bulk material return is needed.
  • the or the deflectors are pivoted or designed as a slide, so that the bumpers by actuation from the conveyor path in or can be taken out of service.
  • a sufficient Degree of mixing can be achieved so that the bottom at the beginning of Spiral channel continuously fed unmixed bulk material is transported upwards to the bulk material discharge, where it is continuous can be carried out.
  • the floor can be used superimposed deflectors of the flow of goods in an inner or outer drop space for further promotion be directed.
  • the discharge flaps or Sliders there are only opened when, if necessary after multiple pass, the bulk quantity arriving there one has reached the desired degree of mixing.
  • a central support tube helically inside and / or outside the Conveyor trough or the conveyor troughs arranged so that this Support tube simultaneously creates an inner drop space into which via the existing deflector parts of the flow of goods to be conveyed can be directed.
  • the support tube has at the lower end a floor with an opening, through which the bulk material can reach the at the bottom of the conveyor and mixing section. The unmixed bulk solids can also be fed through the support tube be abandoned.
  • Screening device for separating oversize particles, such as, for example come about through agglomerate formation.
  • the sieve device is preferably of trough-shaped design and is swinging back and forth, causing the agglomerates can be ground again.
  • the screening device is preferably trough-shaped and at the upper end of the Support tube arranged.
  • the screening device consists of a Perforated sheet or a slotted grating with a perforated or slit width, the the grain diameter of the bulk material is adjusted.
  • drive units for the vibrating channel used two diametrically arranged vibration motors which then have an additional control with a Frequency converter the vibration frequency, conveying speed and thus influence the mixing intensity.
  • the vibrating trough can be equipped with magnetic drives, which are infinitely variable via thyristor control units. At Larger masses are basically the state of the art known thrust crank, unbalance or judge exciter drives used.
  • the basic structure of a vibratory conveyor is in principle according to the State of the art known.
  • Mixing devices consist consistently of a cylindrical Container as a central support tube 10 on which helical inside or outside a conveyor trough 11 is arranged, which a motor-driven vibration exciter 12 obliquely upwards or sinusoidal oscillatory movements directed obliquely downwards generated.
  • the container is over leaf springs 13 and / or Buffer legs 14, for example as hollow rubber springs or Helical compression springs can be designed, supported.
  • At larger machines can also have a (not shown) There is a locking mechanism for the installation.
  • an as is exemplary Slide-trained deflector 21 is drawn in, over the Partial stream is directed to a slide 24 there.
  • About one second slide 23 or a flap there at the upper end of the Vibrating channel can do this during the mixing and conveying process material to be conveyed there also via a slide 24 to be led back.
  • the deflector 21 and the slide 23 can, depending on the bulk material task and mixing process operated in a corresponding manner become.
  • these deflectors 21 be arranged one above the other, each deflector a partial flow leads into the interior of the support tube 10, from where it Partial flow or these partial flows at the beginning of the conveyor section 17 to be led back.
  • the device according to FIGS. 4 and 5 additionally has one the hopper 26 arranged in the device, its degree of filling is measurable with a capacitive level probe 27.
  • this mixing device also has a sieve 28 which is arranged in front of the discharge opening 18.
  • a trough-shaped vibrating screen 29 provided, the coarse filled material as well as arising from the funding Agglomerates. So much for this large piece of bulk material hand flaps are also not grated by sieving 30 are provided, which can be opened to about the vibrating screen 29 or a lecture floor 31 pieces lying to be able to remove.
  • 4 is an inclined plane or a conveyor chute used to feed bulk goods or returned bulk goods to the beginning of the conveyor line move.
  • the mixing device 6 and 7 is similar to that Mixing device according to Fig. 1 and 2a to c constructed, however the conveyor trough 11 formed as a double spiral, as follows works:
  • the goods entered in an upper opening at the beginning 171 is the one given by the inner spiral Conveyed route directed from where the mix to the top is transported from where it via a chute 37 to Beginning of 172 of the conveyor path of the outer coil. Possibly. can an additional feed device 38 for admixing further Bulk material may be provided. That at the beginning 172 of the The conveying path of the bulk material guided on the outer helix is then increased promoted to the end of discharge 18.
  • the mixing device 6 and 7 also has deflector 21 and slide or flaps 23 and finally screening devices for oversize separation or oversize grain.
  • variants are also possible in which three or more helical channels arranged in parallel and, if necessary, several additional bulk goods tasks 38 are provided. Possibly. can be operated such mixing devices that initially only a small proportion of the bulk goods mixed and is screened and only in the course of the mixing and conveying operation additional bulk components via corresponding tasks be added.
