Definitions

  • the invention relates to a device for washing and sorting from organic, clay-like and other impurities continuously supplied coarse and fine-grained solids, such as fresh excavated and prepared gravel, with the material one Feeding slide and showers for the washing trough Washing liquid, consisting of an endless, on support rollers and Belt tensioners supported on the machine frame are supported, the conveyor belt forming the washing trough and one adjoining the washing trough, rising in the direction of belt travel Has part.
  • a device with these features is known (DE 38 39 666.C1), in which the material of a washing trough with the help of a feed chute and showers is fed, the conveyor belt below the Feed chute and against the flow direction of the abandoned Material is arranged increasing.
  • the conveyor belt Knock roller which is coupled to the drive of the conveyor belt.
  • the invention has for its object a device trained in such a way that the separation effect by other feed devices is significantly improved.
  • the Feed chute is arranged such that the flow direction of the fed material is carried out vertically or in the direction of belt travel, the material in the area of the washing trough on the conveyor belt arrives and that before and in the area of the washing trough against the showers acting in the direction of tape travel are provided.
  • feed slide is formed in one or more stages, with a gap at each stage is provided, which is opposite a shower.
  • stages of the feed slide inclined to the conveyor belt, inclined and to the longitudinal direction of the conveyor belt have adjustable sheets, being on the front edge and adjustable baffles can be attached to the rear edge.
  • the top sheet of the Feed slide with a storage section that extends across the entire width is provided.
  • the showers are advantageously arranged so that they can be adjusted in position and pressure.
  • An advantageous embodiment provides that in the area of Washing trough at least one tap roll with its own and controllable drive is provided.
  • the procedure is such that the The machine frame is adjustable in inclination.
  • the invention has the particular advantage that the degree of cleaning of the supplied material is significantly improved and also a higher separation density is achievable. Another major advantage is that the device is very simple to the respective Pollution degree of the material abandoned can be adjusted and differences in density of the material can be taken into account can. There is also the advantage of a lower overall height.
  • the device shown in Figures 1 and 2 has in essentially a conveyor belt 2, the two pulleys 10 and Support rollers 9 is guided, the tape running direction by the arrow 11 is marked.
  • the upper run of the conveyor belt 2 forms approximately starting from the right pulley up to the rising part 3 a washing trough 8.
  • the Drive of the conveyor belt 2 is adjustable.
  • a feed chute 4 with an upper one serves to feed the material Filling opening 26, the direction of flow 12 of the material in The belt running direction 11 is directed and this via the feed chute 4 supplied material reaches the washing trough 8 of the device.
  • an adjustable shower 27 may be provided for the material can be flushed in in the region of the filling opening 26 .
  • the feed slide is designed in several stages so that the material to be cleaned is cascaded the washing trough 8 is fed. In the embodiment shown two stages 14 are provided. Starting from the rising Part 3 of the conveyor belt 2 into the washing trough 8 are individual showers 6 attached, in their inclination, location and Height and pressure are adjustable, with the beam in question is directed against the tape running direction 11. against the right-hand side At the end of the washing trough 8 there are further showers 7, which are also are directed against the tape running direction 11.
  • showers 5, 6, 7 heads are used which have a surface jet produce.
  • the shower 5 is in the area of the feed chute 4 the beam across the entire width and the fall height.
  • the jet extends across the entire width of the Conveyor belt 2. This makes light and unfavorably shaped parts carried out completely.
  • the feed chute 4 is shown in an enlarged view and in the embodiment of Figures 1 and 2 as Dynamic slide formed, a vibrating motor 15 is provided is.
  • An upper, inclined downward adjoins the filling opening 26 Sheet 25 on that with a stowage part going over the entire width 22 is provided.
  • This sheet 18 at the rear edge with a Guide plate 20 and on the front edge 21 with a guide plate 19 is provided.
  • the baffle 20 runs vertically and at the rear edge it remains between the upper plate 25 and the guide plate 20 Gap 17. According to a further stage 14 is below this Sheets 18 another sheet 18 with baffles 19, 20.
  • the baffle 20 on the rear edge 28 can be used for enlargement and reduction of the gap 17 can be adjusted in height. Furthermore, that front baffle 19 adjusted in the longitudinal direction of the plate 18 or 25 and in addition, the sheet can be in total in its longitudinal direction and tilt are shifted. Against the leading edge 21 the sheets 25 and 18 are directed to showers 5, which accordingly in Pressure and inclination can be adjusted. This will in particular ensures that the solids supplied are pre-separated, by deflecting the light parts through the gap 17 to the washing trough 8 while the heavy parts are cascaded over the individual Sheets at the front step 14 get into the washing trough 8.
  • the slide 4 shown in this embodiment is with a Vibration motor 15 designed as a dynamic slide. Also located there is a knocking roller 13 in the area of the washing trough 8 on the conveyor belt 2. Such knocking rollers 13 can also be used in other places of the conveyor belt 2 may be arranged.
  • the knocking roller 13 has its own controllable drive 37 and is arranged laterally on eccentrics 36 (Fig. 9). It is also height and longitudinally adjustable.
  • the Machine frame 1 Subsequent to the rising part 3 of the conveyor belt 2 is on the Machine frame 1 has a drainage device 23 attached in the embodiment shown in Figure 1 as static Drainage device is formed.
  • the one to be drained Material passes through the rising part 3, a feed opening 29 and a drainage channel 30 to an opening 31 for removal of the material, for example on conveyor belts.
