Definitions

  • the invention relates to a method for recovering fine sand from a mining device as a floating grab or floating Bucket chain excavator, the excavated material being drained and over floating conveyor belts is brought ashore.
  • the invention further relates to a device for performing the Process in which the dredged material is a dewatering screen machine transferable with downstream material conveyor and swimming belt is, wherein the screening machine is a drainage deck with a Has drainage covering.
  • the invention has for its object a method or a To design the device of the type mentioned in such a way that the energy requirement is significantly reduced and the device a small Has weight and low wear costs.
  • this object is achieved by the method that under the drainage screen of a screening machine a blind floor installed, which collects the water-fine sand mixture, in Conveying direction and a washing trough as a separating bed Hydro belt separator gives up.
  • the task continues solved in that the screening machine under the drainage deck has a blind floor covering the entire surface, whereby in the conveying direction the end area is provided with a discharge that the discharge is directed to a hydraulic belt separator consisting of a revolving endless conveyor belt with a washing trough as Separating bed and a rising one leading away from the washing trough Part, with the direction of travel of the conveyor belt in the direction of the rise takes place and that the dredged material at the discharge of the screening machine Washing tray of the hydraulic belt separator is passed.
  • a hydraulic belt separator consisting of a revolving endless conveyor belt with a washing trough as Separating bed and a rising one leading away from the washing trough Part
  • the drainage deck is designed as a classifying deck. This makes it possible the complete sand fraction e.g. 0.2 mm separate and on the floating dredger the fine sand and organic parts cut off.
  • FIGS. 1 and 2 In the floating system shown in FIGS. 1 and 2 with A bucket chain excavator 22 is located on a floating body 19 a trestle frame 26 on which the bucket chain excavator 22 is arranged. There is a below the discharge of the bucket chain excavator 22 Horizontal screening machine 1 with a first upper deck 21 and one drainage deck 4 arranged below that with a drainage covering is provided. Located below the drainage deck 4 a blind floor 5, which extends over the entire width and length of the Screening machine 1 extends. The screening machine 1 has a motor 23 provided that a promotion of the drainage deck 4 Material in the conveying direction 6 causes. At the front of the Blind bottom 5 is a discharge opening 8, but instead such a discharge 8 also arranged small chutes on both sides could be.
  • a Hydro belt separator 9 i.e. a known device for Washing out and sorting of organic, loamy and other Impurities from continuously supplied coarse and fine-grained Solids as described in DE 38 39 666 C1.
  • This Device is modified so that an endless conveyor belt 10 runs over two deflection rollers 18 and the belt in the rest at different Support rollers 24 is supported.
  • the top of this conveyor belt is arranged in such a way that starting from the middle to the right a washing trough 11 is formed as a separating bed with a Overflow 16 for the finest material and in the opposite direction there is a rising part 12 with one at the end Fine sand discharge 20, with the conveyor belt 10 in the direction of arrow 13 is driven.
  • the material either arrives via the fine sand discharge 20 Drainage screen 14 or directly on a material conveyor 2 and then a swimming band 3. In case of using a such additional drainage sieve 14 is one Return line 15 with the separating bed 11 of the hydraulic belt separator 9 connected.
  • the installed blind base 5 causes collecting of the water-fine sand mixture, which via this blind floor 5 to Output 8 is carried.
  • This is the drive of the screening machine 1 for transporting the material for transfer to the hydraulic belt separator 9 used.
  • This ensures that a low overall height can be maintained and the sand-water mixture collected high is and thus allowed a downstream drying and Install drainage system. It is important with such floating systems that all superstructures are kept light in weight can be and also adapt to the swimming heel have to.
  • the hydraulic belt separator 9 classifies the water-sand mixture Sharp, with 16 drainage pipes running back into the lake at the overflow. The recyclable fine sand is discharged to the front and on hand over the conveying conveyor belt 2 or if there is more Fine sand over the drainage sieve 14.
  • Drainage deck 4 is designed as a classifying deck and the system so that it can be used for sand preparation.
  • a ball filter 17 can be arranged in the region of the separating bed 11, as described in the earlier patent application 197 38 674.1.
  • FIGS. 3 and 4 floating system differs from the embodiment 1 and 2 only by the arrangement of a floating gripper 25 as a extraction device, wherein between the gripper 25 and a funnel 27 with coarse grate is arranged in the screening machine 1.
