Definitions

  • the invention relates to a method for processing a material mixture, in particular for processing a material mixture that contains at least one lumpy coarse component and a sticky component, and an apparatus for performing the method according to the invention.
  • blade separators for material separation. These are designed in the manner of an excavator bucket, in the bottom of which at least two driven rollers are arranged. Disks and chisels are arranged on these. For material preparation, the material mixture is picked up with this shovel and the shovel is pivoted in such a way that the material contained on the rollers overloaded. The rotations of the rollers let the fine fraction fall between them downwards, while the coarse component remains in the blade separator and can then be tipped out.
  • DE 199 25 502 Cl discloses a method for extracting oil from drilling mud and / or oil-containing drilling mud fractions.
  • coal dust is added to the drilling mud.
  • the resulting suspension is then mixed, after which the mixture is separated into a light and a heavy coal dust oil fraction.
  • the coal dust-oil fraction is then separated off by desorption or extraction.
  • the method according to the invention continuously prepares the material mixture.
  • both the material mixture to be processed and an additive are each fed to a homogenizing and separating device as a continuous stream of material.
  • a water-binding additive can be added to reduce the stickiness of the binding component.
  • the uniform distribution of the aggregate in the material mixture is therefore essential for good separability of the entire coarse component from the entire fine component.
  • the coarse component obtained as a usable product in this way but also the fine component provided with the additive in a sufficient degree of homogenization, so that post-treatment of the fine component can be omitted.
  • a flow equilibrium is established in the homogenizing and separating device between supplied material flows and discharged material flows.
  • the conditions in the homogenizing and separating device can thus be set essentially constant during the operation of the system.
  • the conditions include those present in the homogenizing and separating device Amount of substance, its composition, its speed and direction of movement, the moisture content of the mixture and the composition thereof.
  • the material components forming the mixture can be separated from one another in a single pass through the plant and converted into separately usable products.
  • non-recyclable waste such as sludge or the like.
  • the homogenizing and separating device has a homogenizing section which extends from an input to an output.
  • the material mixture and the aggregate pass through the homogenizing section in the same direction. Separation outputs branch off down the entire length of the homogenization section, which e.g. are formed by gaps between rotating shafts.
  • a moisture-regulating substance is preferably used as the additive, such as, for example, quicklime as powder or as granules, cement, ash, stone powder, granules, fibers (cellulose fibers or others), wood shavings, wood flour, suspensions such as lime sludge bentonite or sealing suspensions e.g. on a plastic basis.
  • the additives are preferably selected such that the cohesive and the lumpy component can be separated better from one another and that the cohesive component, after it has been separated from the lumpy component, has the required or desired physical properties, such as load-bearing capacity or tightness.
  • the amount of the additive supplied per unit of time is measured continuously or from time to time using the Water content of the mixture of materials to be processed.
  • a moisture probe connected to a central controller can be used for this.
  • the moisture can be determined by taking a sample and subsequent testing. On the basis of the physical properties of the sample (formability or directly measured moisture content) it is possible to determine the suitable amount of the additive, for example using a table, and to enter it via an input device in the central control of the processing plant.
  • the system can be designed such that the determined moisture content of the material mixture is entered, after which the central control device determines the required amount of aggregate on the basis of internal calculation rules or tables.
  • the size of the material mixture material flow fed in is regulated, for example, by means of the layer height on a feeding conveyor belt.
  • the layer height is made approximately as large as the largest diameter of the chunks forming the lumpy material component. This represents the lowest possible layer thickness for an undisturbed process.
  • a material mixture feed is preferably used in which the layer height of the material mixture lying, for example, on a conveyor belt and fed in this way is set as low as possible.
  • the width of the conveyor belt can be significantly larger. It is possible to apply the aggregate only as a narrow strip on the material mixture. However, it is preferred to apply it over the entire width, so that within the limits of the accuracy of this technical process, the same uniform layer height of the material mixture with uniform coverage (layer height) of the additive is obtained over the entire width of the feeding conveyor belt. This gives the best prerequisites for good homogenization and thus also for a good separation effect of the homogenization and separation device.

  • the belt conveyor can also be designed as a weighing conveyor.
  • a feed hopper is preferably arranged above the conveyor belt. If it is to be expected that the material mixture contains components that are too coarse, it is considered advantageous to arrange a roller grate in or above the feed hopper for the lateral discharge of excessively coarse components. This prevents very coarse components from interfering with the conveying process when feeding the material mixture.
  • the roller grate arranged above the belt conveyor acts as a material buffer. Discontinuous and abundant material is fed onto the roller grate from the roller grate in a relatively uniform manner to the belt conveyor of the material feeder.
