Definitions

  • the invention relates to a setting machine, in particular a compression setting machine, for the pre-separation of mountains, with a vibrating movable bed in a settling tank filled with separating liquid and with mountains and recyclable material discharge devices arranged therein, and with a vibrating drive.
  • typesetting machines in particular upsetting typesetting machines, are preferably used for coal preparation.
  • These known typesetting machines which are housed in special processing plants, as close as possible to the shaft of the respective mines are dimensioned very large, especially with respect to their height and width, so that they take up a relatively large space.
  • the object of the invention is to improve the known setting machine in its construction so that it can be used in the underground mining area in the route.
  • the setting machine in terms of its height and width, is made smaller than the cross-section of a section of an underground mining area.
  • a setting machine designed in this way has the advantage that it can be used in the underground mining area at the site of material mining to pre-separate the mountains from the valuable materials, for example coal.
  • the particular advantage of using the setting machine according to the invention in the underground mining area is that the mountains mined with the valuable materials directly at the mining site within the respective mining route or in the vicinity of the Mining site can be separated from the valuable materials and therefore only have to be transported over short distances and do not have to be brought to light. By reducing the amount of mountain ballast that can be extracted with raw coal, this results in considerable energy and cost savings.
  • the mining dump site is very advantageously significantly reduced during the day because the previously recovered mining parts are moved directly underground.
  • the setting machine is provided with a movable base in a further embodiment of the invention.
  • the setting machine according to the invention can thus be moved very advantageously as the so-called semi-mobile, for example on rollers or on a sled, into the progressive underground mining area. This also advantageously shortens the distances or distances for the transport of the remaining salvage portions underground, which are returned as filler to areas that have already been mined.
  • the setting machine has an oscillating drive of the setting bed with a horizontally arranged piston-cylinder unit. This enables a particularly low construction or setting machine due to the oscillating drive that engages flat on the setting bed frame.
  • a particularly preferred construction of the S flacne etzmaschine is achieved, when the Setzflub to B ergeaustragsseite back configured as a flat trough and a Bergeaustrag, that is substantially parallel to the flat trough bottom ascending conveying member is flat in its orbital plane.
  • the setting bed which can be rotated on the discharge side, enables a very large stroke and very large pieces can be processed on this setting machine and discharged via the conveying elements.
  • the B ergeaustrag advantageously takes place via a mlaufebene in its U rising substantially parallel to the flat trough bottom conveying member, which is usually Bergeaustrag against the material feed.
  • a conveyor element attached above the conveyor element for the discharge preferably parallel to it
  • the setting machine consists of a setting barrel 1 with a setting bed 2 which is arranged so as to be capable of swinging therein.
  • the setting bed 2 is rotatably mounted on an axle 3 mounted in the side walls of the setting barrel 1.
  • a piston-cylinder unit 4 which is arranged approximately horizontally to the setting bed and whose piston rod 5 is articulated on the frame 6 of the setting bed 2, serves as the oscillating drive.
  • the bottom of the barrel set 1 consists of two inclined parts 7 and 8, wherein according to the invention, the rise of the bottom part 8 out to the horizontal is about 20 0 to Feststoffaustragsende. In this way, the solids discharge is very advantageously facilitated, with a low overall height of the setting machine.
  • two spaced-apart conveying elements 9 and 10 for the lower mountains and upper material discharge which enables a particularly narrow construction of the setting machine.
  • the conveying members 9 and 10 are equipped with drive units 11 and 12 and can be designed, for example, as simple chain conveyors or as double-strand chain conveyors. Chain conveyors enable good dewatering of the solids in the area of the rising bottom part 8 with a high conveying capacity.
  • the reusable materials are discharged from the side of the barrel and the mountains above the front wall by means of chutes or slides.
  • the setting barrel 1 On the left side in the drawing in FIG. 1, the setting barrel 1 has a vertical wall 13, on the outside of which a drive unit 14 is arranged, which is connected via a drive shaft 15 to a solid transport screw 16 arranged flatly over the bottom part 7.
  • a lower sump 20 is arranged directly in front of the vertical wall 13, into which the bulk material sinking to the bottom 7 is transported by the solids transport screw 16.
  • a conveyor element 21, for example a solids pump, is very advantageously connected to the sump 20 for a hydraulic discharge of the cask material.
  • the cask material is conveyed by the conveying element 21 via a pipeline, which is not shown in detail in the drawing, to the conveying element 10 arranged in part 8 of the setting drum 1 for the discharge of valuable material.
  • the setting machine Since the setting machine is made smaller in its external dimensions with respect to its height and width than the cross section of the section 17 shown in FIG. 1, it can be very advantageous in the underground mining operation for the preliminary separation of the mountains that occur during mining with the valuable materials, for example coal be used.
  • the setting machine according to the invention is very advantageously equipped with a movable base 19, consisting for example of a frame and rollers or chains or a slide with slide rails, so that they are connected directly to the respective mining conveyor and, if necessary, a primary crusher and are moved with it can.
  • the mineral-mineral mixture that arises during mining for example the coal obtained during mining
  • a conveyor unit 18, for example a flat conveyor belt of the setting machine on the left in the drawing in FIG. 1 fed and given in the setting bed 2, which is set with the help of the piston-cylinder unit 4 on the axis of rotation 3 in up and down swinging movements.
  • the separating liquid in the settling drum for example water, which pulsates through the openings of the bottom of the bottom of the bed, equipped with a sieve or perforated plate, loosens up the mountains-coal mixture on the bottom of the bed, thus doing so according to different weights stratified that the coal comes to lie on the mountains.
  • the mountains are dammed up by a discharge roller 22 arranged at the end of the setting bed 1, for example a spiked roller, so that a sufficient layer thickness of recovery particles is formed on the setting bed.
  • the discharge roller 22 is fastened in the frame or the raised side walls of the setting bed 2 and is driven by a mechanical drive, not shown in the drawing, for example by means of a chain.
  • the coal lying on the rock layer is also dammed up by a height-adjustable storage wall 23 attached to the riser bed frame. Due to the constant feeding of the raw coal-mountain mixture obtained during mining with the conveyor belt 18 into the setting machine, the sorted raw coal is conveyed via the baffle wall 23 to the upper conveyor unit 10.
  • the setting bed 2 is provided on the solids discharge side in front of the spiked roller 22 with an elastically displaced pressure measuring frame 24.
  • This pressure measuring frame 24 contains several pressure cells which are connected to a regulator via electrical lines. If a freely selectable pressure of recovery parts on the pressure measuring frame 24, for example a setpoint of 300 kg, is exceeded, the drive of the discharge roller 22 is controlled or switched on and the pent-up recovery particles are fed to the lower conveyor unit 9 via the spiked roller 22. It is very advantageously achieved that always sufficient Layer thickness of salvage particles remains on the setting bed 2, so that it is reliably prevented that raw coal pieces get into the salvage discharge and can lead to loss of valuable material.
  • the sorted raw coal is discharged with the upper conveyor unit 10 via a slide from the setting drum 1, while the mountains below it leave the setting bed 2 via the discharge roller 22 and reach the double-strand chain conveyor 9 and are separated therefrom from the raw coal from the setting machine be discharged outside.
  • the cask material that passes down through the openings of the placement bed 2 is very advantageously captured by the solids transport screw 16, which is arranged approximately horizontally in the cask 1 according to the invention, transported into the sump 20, from the solids pump 21 via a pipeline to the delivery unit 10, for example fed to a double-strand chain conveyor and discharged from it together with the rest of the raw coal.
  • the raw coal falling over the baffle wall 23 is transferred to one side or half of the rising bottom part 8 of the setting drum 1 and discharged from there with a chain strand conveyor 27 from the setting drum 1.
  • the recovery particles are guided through a guide plate 29 to the other side or half of the rising bottom part 8 of the setting barrel 1 and discharged from the setting barrel 1 with a further, parallel chain strand conveyor 28.
  • the line at which the conveyed solids emerge from the separating liquid is identified by 30.
  • the distance or the distance 31 between the line 30 or the emergence of the solids from the separating liquid and the discharge of the solids via the front upper edge 32 of the rising bottom part 8 of the setting barrel 1 must be long enough to convey the solids from the setting barrel 1 to achieve adequate drainage of the solids by means of the chain conveyors 27, 28 shown in FIG. 2, for example.
  • the fact that the water in the setting machine does not have a transport function (only when conveying the cask goods from the sump 20 by means of the solids pump 21 to the material discharge device 10 or 27), but rather only serves as a separating function, can be very advantageous due to the sufficient dewatering of the solids wastewater treatment can be dispensed with.
  • the setting machine according to the invention is also particularly suitable for the preparation of coarse-grained feed material, for example from 30 to 400 mm piece size.
  • the water does not need to be kept clean be, so that the setting machine only works with a filling of separation liquid or water. It is only necessary to replace or supplement the surface water adhering to the discharged sorted mountain and raw coal material.
  • suitable conveying means 35, 36 for example belt conveyors (or vibratory conveyors when the conveying direction changes), and are used according to their further use transported away.
  • the mountains remain as a filler for removed sections or struts underground, the sorted raw coal can be fed to further underground processing stages (e.g. crushing, screening, sorting of heavy sludge) or brought to light with reduced lifting capacity.
  • this setting machine designed according to the invention can be used in the underground mining operation for pre-separating the mountains from the valuable materials, such as coal, ores or other minerals obtained by mining (for example bauxite), and due to the movability of the setting machine Moving up is made possible as the route is progressively reduced.
  • the mountains resulting from the preliminary separation can very advantageously remain in the underground mining as a mountain offset, that is to say as filling material, or the like and do not need to be brought to light. By sorting out the mountain ballast, this relieves the burden on the route and shaft mining and thus saves a great deal of energy and costs.
  • FIGS. 3 and 4 Another advantageous embodiment of a compression setting machine is shown in FIGS. 3 and 4.
  • the setting barrel 1 there is a setting bed 2 which is rotatably displaceable about the axis 3 on the discharge side.
  • the piston-cylinder unit for driving the setting bed 2 is not shown; it is attached in such a way that it does not protrude beyond the minimum height due to the size of the setting barrel and the mountains discharge device 9.
  • the setting barrel 1 is also designed as a flat trough towards the mountain discharge side. Uer rise of the floor 8 is also 20 ° here. At the same time, the conveyor belt 9 for the recovery is running.
  • the coal is discharged laterally through the screw 40 above the setting bed 2.
  • This discharge enables a rather narrow construction of the typesetting machine.
  • it can also be designed as a semi-mobile and moved with the mining conveyor.
  • FIG. 4 A cross section through this setting machine at the level of the discharge screw is shown in FIG. 4.
