Definitions

  • the invention relates to a light material separator for fractionating a mixture of substances by means of swim-sink sifting, with a wash trough that can be filled with water, which has an entry opening for charging with a mixture of substances to be fractionated, with a screw conveyor that can be rotated inside the wash trough and that is used for charging a from the wash trough provided discharge opening is used with sinkings, and with a brush belt aligned transversely to the longitudinal extension of the screw conveyor, which serves to feed a discharge chute interacting with the brush belt with floating material.
  • a generic light material separator is from the DE 20 2009 004 788 U1 known.
  • the previously known light material separator has a washing trough.
  • a screw conveyor is rotatably arranged inside the washing trough. In normal operation, the wash trough is filled with water.
  • the sunk components i.e. the sediment
  • the sediment is conveyed to a discharge opening provided by the washing trough by means of the screw conveyor, which rotates during operation.
  • the sediment is discharged through this.
  • the light materials are skimmed off the surface of the water by means of the sweeper belt, which moves during operation, and discharged via a discharge chute that interacts with the sweeper belt.
  • the screw conveyor is not only used to transport the sediment to the discharge opening. It also requires mechanical force to be applied to the sediment, so that light materials adhering to the sediment may be separated from the sediment. A more effective fractionation of the substance mixture into sinkings on the one hand and floating material on the other hand is thus achieved in an advantageous manner.
  • the invention proposes a lightweight material separator of the generic type, which is characterized by its own running gear.
  • the light material separator has its own chassis.
  • the light material separator according to the invention is thus itself mobile. This advantageously allows the lightweight material separator to be used in a variable position at the place of use. This results in significantly simplified handling, because the light matter separator according to the invention can be positioned as desired by the user at the place of use and, if necessary, also repositioned. In addition, transport to the place of use or transport away from the place of use can be carried out in a simplified manner.
  • the one from the DE 20 2009 004 788 U1 previously known light material separator is designed as a purely stationary machine to be used.
  • the previously known light material separator has a transport device in the form of an eyelet, which is designed to match the standardized container hook system according to DIN.
  • a separate transport machine is required for transport, which lifts the light material separator by means of a crane device and jacks it up on a carriage.
  • the configuration according to the invention not only enables simplified transport, it also allows repositioning at the place of use itself, which is not possible with the stationary configuration according to the prior art. All in all, the design according to the invention proves to be particularly easy to handle.
  • the chassis Has chassis with two, preferably four wheel units. Accordingly, a chassis is used which has a chassis and wheel units arranged thereon. At least one wheel unit is provided on each longitudinal side of the chassis, which means that the chassis has a total of two wheel units. This embodiment is particularly manoeuvrable. Four wheel units can also be provided for an increased load capacity, in which case there are two wheel units per longitudinal side of the chassis.
  • a chassis that has a chassis with two caterpillar arrangements.
  • a caterpillar arrangement is provided on each longitudinal side of the chassis. This embodiment is particularly suitable for rough terrain.
  • the lightweight material separator can be operated like a trailer thanks to its running gear. For transport, it is easy to couple to a towing vehicle. A repositioning at the place of use can also be done by means of a towing vehicle or manually.
  • the light material separator is designed to be self-propelled and has a drive device for a wheel unit and/or a caterpillar arrangement.
  • the advantage of this embodiment is that it does not require a towing vehicle, in particular for transporting the light material separator.
  • the light material separator is equipped with a drive device that enables it to be driven by itself. This means that both transport and repositioning at the place of use can be carried out without additional tools or machines. The handling of the light material separator according to the invention is thus improved once again.
  • the drive device has an autonomous power supply.
  • This autonomous energy supply can be, for example, a diesel-powered generator, ie a diesel generator.
  • a connection to an external energy supply, for example by means of a power cable to the public power grid, is not required in this respect, so that the light material separator according to the invention can be operated completely independently. This is particularly advantageous when the light material separator is located at a remote location or places that are not further developed.
  • the screw conveyor and/or the brush belt can be driven by means of the drive device.
  • the drive device not only serves to drive the wheel units and/or the caterpillar arrangements, but also the conveyor screw and/or the brush belt.
  • Appropriate power transmission devices are provided for this purpose, which couple the drive device to the screw conveyor and/or the brush belt in a force-transmitting manner.
  • both the screw conveyor and the brush belt each have an electric drive motor. During operation, these draw their power from a diesel generator in the drive unit.
  • a conveyor belt is provided which cooperates with the discharge opening.
  • sediment conveyed by the screw conveyor is discharged through the discharge opening.
  • the optional conveyor belt is provided for removing the sinkage. In this way, it is possible in a targeted manner to form sediment heaps that are easier to transport away.
  • the conveyor belt can be transferred from a non-use position into a use position cooperating with the discharge opening and vice versa.
  • the conveyor belt can be brought into two positions, into the non-use position on the one hand and into the use position on the other hand.
  • the conveyor belt interacts with the discharge opening and can, in the already prescribed manner, transport away the sediment that has been discharged via the discharge opening and dump it away from the light material separator.
  • the conveyor belt is preferably accommodated in a space-saving manner, which is advantageous for transporting the light material separator to or from the place of use.
  • the conveyor belt is arranged on the washing trough so that it can be displaced in the longitudinal direction of the washing trough and is located at least partially below the washing trough when it is not in use.
  • the Conveyor belt can be shifted as an extension of the washing trough, whereby it is extended in the use position and retracted in the non-use position. In the non-use position, it is located at least partially below the washing trough to save space, which leads to a significant shortening of the lightweight material separator in the longitudinal direction compared to the use position.
  • the conveyor belt has a first section and a second section that is pivotably arranged on the first section.
  • the pivotable second section of the conveyor belt can be used for transport purposes, i.e. it can be given away in relation to the first section. This also allows the conveyor belt to be accommodated in a space-saving manner for transport.
  • the conveyor belt can also be driven by means of the drive device.
  • an electric drive motor can be provided for driving the conveyor belt, which is supplied with electrical energy by the diesel generator of the central drive device.
  • a further discharge chute interacting with the brush belt is provided, with the brush belt serving to feed one of the two discharge chutes with floating debris, depending on the running direction.
  • the broom belt has a circumferential band that is covered with broom bristles on the outside. In operation, these drive over the water surface of the water stored by the washing trough and take floating debris with them. The floating debris taken along in this way is conveyed to a discharge chute, via which it is then discharged.
  • By simply changing the discharge direction, ie changing the direction of rotation of the drive motor of the brush belt can be done on the one hand an adaptation to the respective spatial conditions.
  • the light matter separator according to the invention has a wind sifter in addition to the washing trough for carrying out a swim-sink sifting. It is thus permitted to carry out two consecutive sightings for fractionation, which yields an improved fractionation result.
  • the density of the components in the mixture of substances to be fractionated plays a decisive role.
  • the density alone is not always sufficient as a criterion for separation.
  • particles with a size of 10 cm to 20 cm in width or length or even larger i.e. particles with a size of 10 cm to 20 cm in width or length or even larger.
  • a combination of an existing separator with an air classifier can help here because not only the density alone but also the geometric shape of the particles plays a role.
  • using an air classifier comparatively small particles with a high density as well as comparatively large particles with small densities can be expelled, depending on the geometric shape. This relates in particular to wood particles, foils and/or packaging tapes present in mixed construction waste, for example.
  • the wind sifter is arranged upstream of the entry opening in the direction of entry of the mixture of substances. Accordingly, the wind sifter is used in front of the sink-float separator.
  • This constellation yields the benefit of increased throughput. Because the mixture of substances to be fractionated is first fed through the air separator, before the residual material not expelled by the air separator is fed to the sink-float separator. This led to the fact that, in contrast to the prior art, less material mixture to be fractionated is fed to the sink-float separator with the same amount of starting material. As a result, the throughput can be increased with the same amount of feed.
  • the wind sifter has a feed or inlet connection piece which is compatible with the entry opening and covers it in the final assembled state.
  • the wind sifter can therefore be mounted directly on the entry opening provided by the wash trough.
  • the mixture of substances to be fractionated is thus fed into the washing trough with the interposition of the air classifier.
  • the wind sifter has an outlet connection opening into an outlet opening.
  • the material fractionated by the wind sifter is discharged through this outlet connection.
  • the wind-sifted material is discharged via the outlet nozzle of the wind sifter, which enables stockpiling as well as catching in a container or bin provided for this purpose.
  • the wind sifter is downstream of the discharge opening in the discharge direction of the debris or that the wind sifter is downstream of the discharge chute in the discharge direction of the floating debris. According to this embodiment, therefore, a downstream air separation of either the debris and/or the floating debris can take place.
  • This variant of the invention is particularly advantageous in the case of mixtures of substances which have a comparatively high level of homogeneity with regard to the density of the individual components. Because in this case the error rate of the sink-float separator is comparatively high, so that with a downstream air separator, a significant improvement in the fractionation result can be achieved.
  • figure 1 shows the light material separator 1 according to the invention according to a first embodiment in a schematic perspective view.
  • the light material separator 1 has, in a manner known per se, a water trough 2 that can be filled with water figure 5 reveals.
  • the screw conveyor 4 is rotated by means of an electric drive motor 24.
  • a conveyor belt, a conveyor mat or the like can alternatively be provided for conveying out the sediment.
  • the washtub 2 provides an entry port 3 . Through this, the washing trough 2 is loaded with a mixture of substances to be fractionated.
  • the mixture of substances fed into the washing trough 2 consists of a fraction of comparatively heavy components and a fraction of comparatively light components.
  • the heavy components sink down as sediment in the water stored in the water trough 2 .
  • the comparatively light components i.e. the light materials, float as floating material, whereby the comparatively heavy components are separated from the light materials in a swim-sink classification.
  • the sediment is transported to a discharge opening 5 provided by the water trough 2 by means of the screw conveyor 4 .
  • the light material separator 1 has a conveyor belt 25 which is connected to the discharge opening 5 and interacts with it. About the discharge 5 delivered Sunk material thus reaches the conveyor belt 25 and can be transported away by means of it.
  • a brush belt 8 is used to remove the floating light materials.
  • the brush belt 8 is aligned transversely to the longitudinal extension 7 of the screw conveyor 4 and has a circumferential belt 9 that is covered with brush bristles 10 on the outside.
  • the broom belt 8 interacts with two discharge chutes 11 and 12 .
  • floating light materials are taken either to the discharge chute 11 or to the discharge chute 12 and are placed on them.
  • the rear view figure 4 reveals this connection.
  • the washing trough 2 and the broom belt 8 form a sink-swim separator 39 in functional combination.
  • the light material separator 1 is equipped with a chassis 14 .
  • the chassis 14 has a chassis 15 with two caterpillar arrangements 17 and 18.
  • the light material separator 1 is designed to be self-propelled and has a drive device 20 for the caterpillar arrangements 17 and 18 .
  • the drive device 20 has, among other things, a self-sufficient energy supply 21 in the form of a diesel generator. Furthermore, the drive device 20 has hydraulic motors which drive the caterpillar arrangements 17 and 18 hydraulically. A hydraulic pump 23 is provided for this purpose, which is supplied with electricity by the diesel generator 21 .
  • the electric drive motor 24 for the screw conveyor 4 and the electric drives for the brush belt 8 and the conveyor belt 25 are also supplied with electricity by means of the diesel generator 21 .
  • the Light material separator 1 energetically self-sufficient. This advantageously allows the light material separator 1 to be operated without an external energy supply, be it for transport or repositioning of the light material separator 1 or for carrying out a fractionation as intended.
  • an external power supply can also be provided via a power supply connection.
  • the switching and control technology for the diesel generator 21 and the other electric motor drives are housed in a switch box 22 .
  • the water trough 2 is inclined at an angle of 20° to 30° to the horizontal.
  • the water trough 2 in the operating position is filled with water, for which purpose the water trough 2 has a water inlet 28 .
  • a water drain 29 is provided for draining water.
  • the water level in the washing trough 2 is kept constant by means of an automatic level control in order to compensate for water losses that are essentially caused by the discharged sediment.
  • the conveyor belt 25 is arranged on the washing tub 2 in various ways in the longitudinal direction thereof. This allows the conveyor belt from the to the Figures 1 to 5 to spend the use position shown in a non-use position in which the conveyor belt 25 is arranged at least partially in the vertical direction 19 below the water trough 2.
  • the non-use position also called transport position, is in the Figures 6 to 9 shown.
  • the washing trough 2 is arranged on the chassis 14 such that it can be pivoted at one end.
  • the washing tub 2 is supported by supports 30 at the other end. These supports can be folded down by pivoting, which causes the washing trough 2 to pivot.
