Definitions
- the invention relates to a method for separating bulk goods with first and second components of different structure.
- the first component can be light and fine-grained, the other component, however, consist of coarse and relatively heavy parts.
- the task may be, sand or crushed organic material (wood) first
- Free part of stones, metal parts or coarse pieces of wood as a second component It may also be necessary to separate material of smaller specific weight from material with larger specific weight.
- the invention has for its object to provide a method and an apparatus which enables a separation of such different components of a bulk material in a simple manner and with high throughput.
- An inventive method for solving this problem is that the bulk material is placed on an inclined, obliquely upward conveying conveyor belt, the components differ in their adhesion to the conveyor belt and the conveyor belt is arranged so that the first components on the upper end and and the second components are discharged at the lower end of the conveyor belt.
- the invention is based on the knowledge that different components of a bulk material - for example, in the extreme case crushed organic waste as the first component and pebbles as the second component - generally also show different adhesion on the conveyor belt. According to the invention, these different properties are used to separate the components: if the conveyor belt runs exactly horizontally, then both components are taken to the discharge end, the "upper end" when the conveyor belt is inclined. If the conveyor belt is set very steeply, then both components slide down even when the conveyor belt is running. The conveyor belt does not take the components at all. In between there is an inclination of the
- Conveyor belt in which the one component, which has greater adhesion to the conveyor belt, is carried along by the conveyor belt, while the other component slides or rolls down against the conveying direction of the conveyor belt.
- the entrained component is carried out at the upper end of the conveyor belt. This can simply be that this component over the top of the
- Conveyor belt is dropped.
- the component that is not taken away is discharged at the lower end.
- a different inclination of the conveyor belt may be required to achieve this effect.
- Bulk goods with first and second components of different structure contain an inclined conveyor belt with a lower and an upper end, means for feeding the bulk material onto the conveyor belt, first means for discharging the first components of the bulk material at the upper end of the conveyor belt and second means for discharging the second one Components of the bulk material at the lower end of the conveyor belt, the components differing in their adhesion to the conveyor belt and the conveyor belt is arranged so that the first components are discharged at the upper end and the second components at the lower end of the conveyor belt .
- Embodiments of the invention are the subject of the dependent claims.
- An exemplary embodiment of the invention is explained in more detail below with reference to the accompanying drawing, which shows the structure of a device for separating bulk materials in a highly schematic manner.
- a conveyor belt is designated.
- the conveyor belt is inclined from the bottom right to the top left in the figure.
- the conveyor belt 10 is driven counterclockwise in the figure and accordingly demands from bottom right to top left.
- Conveyor belt 10 forms an upper end 12 with a deflection roller 14 and a lower end 16 with a deflection roller 18.
- the conveyor belt 10 consists e.g. made of rubber and has a smooth surface 20, i.e. does not carry carrier strips or the like.
- the conveyor belt 10 can be pivoted as a whole about a pivot axis 22 relative to the structure 24.
- the pivot axis 22 coincides with the axis of the deflection roller 18.
- the conveyor belt 10 is pivoted by an actuator 26 in the form of a hydraulic actuating cylinder.
- Means 28 for feeding bulk material onto the conveyor belt 10 are arranged above the conveyor belt 10.
- Conveyor belt 10 contains a vibrating trough 30.
- the vibrating trough 30 is set in motion by a drive 32 and an eccentric gear 34 in such a way that it conveys the bulk material to the left in the figure.
- a filling funnel 36 is attached above the vibrating trough 30.
- the vibrating trough is arranged so that the bulk material is fed in between the upper and lower ends 12 and 16 of the conveyor belt at a longitudinal distance.
- a second conveyor belt 38 is arranged below the lower end 16 of the conveyor belt 10. This second conveyor belt 38 extends perpendicular to the conveying direction of the conveyor belt 10 perpendicularly out of the paper plane of the figure.
- the conveyor belt 38 represents "second means for discharging the second components of the bulk material at the lower end of the conveyor belt 10".
- the entire arrangement with the conveyor belt 10, the means 28 for feeding the bulk material onto the conveyor belt 10, the means for discharging the first component of the bulk material at the upper end 12 of the conveyor belt 10, which here practically extends from the freely projecting upper end 12 are formed themselves, and the means for discharging the second component of the bulk material at the lower end of the conveyor belt 10, here the second conveyor belt, are arranged together with the drive means (not shown) on a mobile chassis 40.
- the method consists in that first the inclination of the conveyor belt 10 after
- the components of the conveyor belt to be separated is set. So e.g. starting from a horizontal position of the conveyor belt 10 bulk material with the two components to be separated via the shaking channel on the conveyor belt 10. Both components initially run to the left in the figure. Then the inclination of the conveyor trough 10 is increased until the first component with higher adhesion is taken to the upper end 12 of the conveyor belt, but the second component slides or rolls down to the right in the figure to the lower end of the conveyor belt.
- the first component of the bulk material is taken to the upper left end 12 of the conveyor belt 10 and falls beyond this end onto a rent to be created or a transport vehicle.
- the second component of the bulk material slides or rolls to the lower left end 16 of the
- Conveyor belt 10 and falls on the second conveyor belt 38. There, the second component is discharged to the side.
- the structural differences of the components can be that the first components are smaller than the second components. However, instead of or in addition, the first components can also be lighter than the second components.
- the second component can be stones or metal parts.
- the second components can also be rough pieces of organic material (wood).
- the first component can be sand.
- the first component can also be shredded, organic material.
