Definitions

  • the invention relates to a device for removal of screenings and / or screenings from one with Solids contaminated liquid according to the generic term of claim 1.
  • Devices of the type mentioned here are known. They are used to remove solids from a liquid to carry out. For example, you will be in Channels used in which rainwater and / or waste water flows to a sewage treatment plant. From the liquid all suspended solids are discharged, that can affect the sewage treatment plant. It is also possible such devices in containers use in which a solid-liquid mixture is contained and from which the solids are discharged will.
  • the solids are discharged using a Conveyor partially into the liquid immersed and water permeable in some areas Covered, in which a rotating screw conveyor or spiral is arranged.
  • the screw conveyor / screw is made of solids the liquid is discharged and to a discharge opening transported. It is essential that the Solids before dropping into a suitable one Containers are compacted and drained. Within the jacket is a compacting or Compression zone in which the screw conveyor / screw does not interfere with the solids stands. The material feed within this Area only takes place here to the extent that Solids fed from the conveyor will.
  • the solids are in the compression area due to the friction effect of the inner surface of the coat with the solids into a plug condensed, which preferably not with the Conveyor screw / spiral turns.
  • a device with proposed the features mentioned in claim 1. This is characterized by the fact that one opposite the solids discharged from the liquid fixed transport resistance is provided is assigned to the inner surface of the jacket is. Such transport resistance is very easily realizable and causes that from the Liquid discharged solids held and thus be compacted, so that drainage the solids is possible.
  • the transport resistance comprises one or more ring segments, preferably on an imaginary circular line are arranged. It is also conceivable that To form transport resistance as a closed ring, so that a particularly large one, in the Any remaining solids discharged acting, resistance is realized.
  • An embodiment of the is also preferred Device which is characterized in that the Transport resistance at least one elongated Includes strips that are preferably parallel to the The axis of rotation of the screw conveyor / spiral runs and whose - seen in the direction of conveyance - rear end is displaceable so that its distance from the inner surface is variable.
  • the Transport resistance at least one elongated Includes strips that are preferably parallel to the The axis of rotation of the screw conveyor / spiral runs and whose - seen in the direction of conveyance - rear end is displaceable so that its distance from the inner surface is variable.
  • the removal device described below of screenings and / or screenings is in the following briefly referred to as screw conveyor 1.
  • the in Figure 1 includes screw conveyor 1 shown a conveyor 3 which engages in a channel 5, namely, in a sewer that runs from Liquid in the indicated by an arrow Direction, here from left to right, flows through becomes.
  • the conveyor 3 extends to Bottom 7 of the channel and is designed so that all of the liquid present in the channel 5 through the lower area of the conveyor 3, which here comprises a water-permeable jacket 9, must flow through.
  • To the left of the conveyor 3 is a mixture of liquid and solids. The solids arrive with the incoming liquid in the lower, counter the flow direction indicated by an arrow open coat and passes through the sieve area 11 of the coat. Solids get into and here the U-shaped jacket part from a conveyor helix or screw conveyor the sieve area 11 discharged upwards. Above of the screen area 11 is the jacket 9 essentially cylindrical.
  • the conveyor 3 is preferably in their lower area with a shaftless conveyor spiral formed by one opposite the screen area 11 Motor 13 via a transmission 15 in Rotation is set.
  • the torque of the engine 13 is introduced into the feed spiral via a shaft 17, the one in its top, that is, the engine 13 facing end, in a screw conveyor 19th transforms. That means the helix is on its top End penetrated by shaft 17.
  • the screw conveyor 1 with a self-supporting Conveying spiral provided at its lower end has no stock.
  • the funding spiral rests on at least one, preferably three, also as a bearing rail acting strips, one of which is here First strip 25 lying at the base of the jacket 9 and a second circumferentially spaced second strip 27 are shown.
  • the Stripes 25 and 27 extend to the discharge opening 21 and are therefore also in an area in which the screw conveyor 19 does not protrude.
  • a transport resistor 31 is provided here is assigned to the inner surface 33 of the jacket 9.
  • the transport resistance 31 directly on the inner surface 33 applied. He is here as a continuous, Ring arranged concentrically to the shaft 17 educated. However, it is possible to use one Ring on fastening rods also on the To attach end wall 35 of the conveyor 3.
  • the transport resistance can also be through a several ring segments can be realized on one imaginary circular line are arranged.
  • Figure 1 is a stripping device below the end wall 35 36 provided in one area - seen in the conveying direction - above the compression area 29 arranged and on a helical section 38 is attached, the opposite Inclines, like the screw conveyor 19th
  • the scraper is used in the compression area 29 condensed good from that material fed via the screw conveyor 19 is shifted upward along the shaft 17 to strip off, so that this through the discharge opening 21 are dropped into the collecting container 23 can.
  • the compressed material forms one around Shaft 17 plug around by the scraper 36 quasi peeled and from the Shaft is removed.
  • Through the spiral section 38 becomes existing above the stripping device 36 Material is conveyed back into the discharge opening 21, so that a material jam in the area of the front wall 35 is safely avoided.
  • FIG. 2 shows the compression range again 29 shown enlarged. It is clearly too recognize that the screw conveyor in front of this compression area ends so in this area no existing solids from the screw conveyor touched directly, but by those who are promoted Solids are advanced further.
  • the enlarged representation in FIG. 2 becomes once again seen that the transport resistance 31 formed here as a closed ring which rests on the inner surface 33 of the jacket 9 and attached in a suitable manner.
  • the cross section of the transport resistance is arched here trained, that is, the trained as a ring Transport resistance lies with a flat Base on the inner surface 33 and bulges towards the axis of rotation 37 of the screw conveyor 19.
  • the curvature can be semicircular be. It is also conceivable to unite the ring triangular, rectangular, square or trapezoidal To give cross section.
  • Figure 3 shows a modified embodiment of the Compaction area 29 of the screw conveyor 1.
  • the transport resistance 31 is here by elongated Resistance elements formed, one first resistance element through the first strip 25 and a second resistance element by a here diametrically opposite second stripes 25 'is formed, which extends over the compression range 29 to the top section of the screw conveyor 19 extends.
  • the seen in the conveying direction rear ends 39 and 39 'of strip 25 and 25 'are displaceable. Through the more or less far inside the Jacket 9 protruding ends 39 and 39 'of Strips 25 and 25 'will also rotate in the Compression area 29 existing solid graft prevented very effectively.
  • the free ends 39, 39 'of the strips 25, 25' can by an actuator 41 or 41 'more or less far inside the jacket 9 or more or less far to Axis of rotation 37 are pivoted.
  • the actuator 41 has an adjusting screw 43, which here attached to the jacket 9 via a mounting element 45 is and which reaches through the jacket 9 and on the End 39 of strip 25 acts. Will the set screw 43 more or less screwed in, so the end 39 will be more or less far towards pivoted to the axis of rotation 37. Because the End regions 39 and 39 'more or less far in the inside of the jacket 9 in the compression area 29 engage, a transport resistance 31 is realized, the one ramp 40 or 40 'for that delivered by the screw conveyor 19 Well trained.
  • the freedom within the Jacket 9 is due to the inwardly projecting strips 25 and 25 'so narrowed that the conveyed good braked and thus compressed and drained becomes.
  • the end region of the Stiffens 25 ' is like the strip 25 on suitable Attached to the inner surface 33 of the jacket 9.
  • the actuating device 41 ' is constructed identically, so that their structure is not discussed in detail becomes.
  • Figure 4 shows a cross section along the line IV-IV through the mantle 9. Concentric to that in particular preferably in the compression region 29 cylindrical jacket 9 is the Wave 17.
  • the screw conveyor 19 is through a Circle line indicated. It is clearly recognizable that the screw conveyor 19, as well as the further the conveyor spiral below rests on three strips, of which the underlying strip 25 with the actuator 41 cooperates. Symmetrical to the lower strip 25 there are two strips here 27 and 27 '. It is possible to do this Arrange strips also asymmetrically and also to provide more than three strips. It is essential that the strips as wear-reducing bearing strips serve, especially when the screw conveyor no storage in its lower area and, as indicated above, as shaftless Funding spiral is formed.
  • a conveyor 3 as based on of the figures was explained, also in a container, a basin or the like can be used can to remove solids from a liquid.
  • Such containers, basins or the like are used, for example, for cleaning solids used. So it is possible with a conveyor the solids of the type described here discharge from the liquid.
