Definitions

  • the invention relates to a method and a vibratory conveyor for treating items to be cleaned according to the generic term of claim 1 and claim 4.
  • the raiding weirs are intended to ensure that Sand accumulated and this creates additional pressure that pushes the residual water out of the mixture.
  • the Sand that has passed over the raid weirs then becomes seamless conveyed in the longitudinal direction of the channel to the reclassification section, in the wide-meshed sieves are provided, which is another Separate the grains of sand.
  • the uniform Vibrating screen section with different screen sizes and additional hold-up weirs is only for drainage and separation of a water-gravel mixture is suitable because the treatment consequences are only intended for this. In particular is the cleaning of a dry material to be treated with it Combined vibratory conveyor not possible.
  • DE 38 25 223 A1 describes an oscillation system for separating one Mixture of sand, water and contaminants known.
  • This system consists of a vibrating box, which is a setting zone in the discharge area of the mixture, at which a drainage zone connects in the direction of the vibratory feed.
  • the setting zone consists of the sand-water mixture of sand off the ground while the light impurities float up and sorted out via an overflow.
  • a baffle is arranged, a passage gap to the bottom of the swinging box leaves free. Through the running in the longitudinal direction of the swinging box The deposited sand in the Drainage area promoted in the bottom area Sieve is provided.
  • the sieve bottom serves for drainage and for fines screening through above the drainage section provided washing nozzles is improved.
  • This plant too is for separation and dehumidification only water-containing sand mixture suitable because the treatment sequence by the linearly running in the swinging box longitudinal direction Vibration and seamless transfer in the vibrating box can only be tuned to a water-sand mixture.
  • this screening plant is insufficient for cleaning of dry raw materials, because only a washing stage for the treatment of raw materials is provided is in which by the linear direction of vibration in Swing box longitudinal direction only easily removable impurities are removable.
  • the invention is therefore based on the object of a method and a device for cleaning raw materials create, in which all necessary treatment stages with be carried out with the least possible expenditure on equipment can.
  • the inventive solution to the task is based largely to train a vibrating conveyor trough and in the screw-like movement of the conveyed material transversely to the conveying direction to provide at least one or more partition walls, the necessary treatment processes when cleaning the raw materials functionally in a vibrating conveyor trough separate, so that several in a vibrating conveyor independently treatment stages that can be carried out from one another become.
  • the invention has the advantage that by the separation by one or more partitions a variety of treatment processes within a single vibrating trough become.
  • this not only means the expenditure on equipment to be kept low, but this is also a shortening the processing time and the processing route possible.
  • partitions can also be retrofitted and changed are such a vibrating trough with partitions to the most diverse cleaning processes and the most varied Cleaning goods are adjusted.
  • these partitions both vertically and inclined in the conveying direction, triangular, be trapezoidal or round, so that this advantageously the transition to the next treatment stage is influenced favorably. Furthermore, by the height and location of the partition walls not only the intensity the treatment stages influenced in an advantageous manner but also the conveying speed.
  • Vibrating conveyor trough in which the Vibrating conveyor trough is tubular, can be advantageous Way the noise level generated and in particular the energy expenditure during the drying process as well as the machine room pollution be kept low.
  • a treatment section additionally inside the Vibrating drum also helical guide body be provided, even with largely symmetrical raw materials like round stones or sugar beets and the like the self-cleaning effect and mixing of each Improve the treatment process in an advantageous manner, since this largely causes the tendency to curl to the inside of the roll can be prevented.
  • Fig. 1 of the drawing shows a schematic vibrating trough 2, the three separate treatment areas 6,8,16 for one item to be cleaned which is separated by two partitions 12, 13 are separated.
  • 2 of the drawing shows a cross section through such a channel 2.
  • the vibrating channel 2 is tubular and provides one closed vibrating drum.
  • the tubular vibrating trough 2 is on bearings 11 and spring elements 15 on a foundation 18th or supported a frame.
  • the vibrating channel 2 is through two vibration exciters 20 with the aid of a drive device driven.
  • linear vibration exciters are preferred or judge exciter used.
  • the vibration exciter generate vibration or force components vertically and transversely to the conveying direction 7 and thus to the channel longitudinal direction.
  • In the Channel 2 results in an asymmetrical distribution of goods with a good surface that runs obliquely to the horizontal 23.
  • Fig. 2 is the good layer or which is in the vibrating trough the setting of the distribution of the conveyed goods.
  • the items to be treated are at an entry area 1 21 fed to the vibratory conveyor trough 2 and arrives first into a washing area 10.
  • the items to be cleaned 21 broken stones, for example, from adhering Dirt and dust components should be cleaned.
  • the broken stones are polygonal and have a diameter up to approx. 30 cm.
  • In the vibrating drum 2 can also other raw materials are cleaned, including semi-finished parts and organic raw materials or coarse-grained bulk goods would be conceivable.
  • the washing area 10 comprises a conveyor line up to one first partition 12, for example about 1/3 of the length of the vibrating trough includes.

  • the partition 12 is watertight and sealed from the vibrating drum. With special treatment methods, openings or passages could also be provided in the partition wall 12.
  • the height of the partition is dependent on an optimal degree of filling of the vibrating drum and is advantageously about a quarter of the drum height, but can also be made higher or lower if there are special requirements for the cleaning effect or the throughput.
  • An example of a flat design of the partition 12 can also be installed inclined in the conveying direction 7 in order to achieve a gentler or faster material transfer to the subsequent treatment stage.
  • the vibration excitation results in the washing area 10 the vibrating drum has a helical circulation of the items to be cleaned 21, reducing the cleaning effect and promoting is achieved.
  • the vibrating conveyor trough 2 can in the longitudinal direction of the trough 7 roughly horizontal, but also falling or rising be arranged. With a horizontal arrangement, the vibration exciter 20 also power or excitation components in the Generate main conveying direction 7. This is in a falling order not necessary, since the material to be treated 21 is thereby the gravity component is transported in the main conveying direction 7 becomes. When the channel arrangement increases, the excitation component must be be so large in the slope direction that the gravity component overcome and at the same time still a funding movement is achieved in the main conveying direction 7.
