Definitions

  • the invention relates to a device for removing and / or screening material from liquid flowing in a channel, with a screw conveying device with a drive, which extends obliquely upwards at an installation angle, extends approximately to the bottom of the channel and, if necessary, partially dips into the liquid.
  • Housing and conveyor spiral conveyor section for the screenings which leads to a discharge point above the channel, where a separator in the form of a grate, sieve or the like is provided.
  • Such a device can be used in particular in sewage treatment plants, but can also be used advantageously for other areas of technology, for example in the textile industry, the plastics industry and the like. the like
  • a device of the type described in the opening paragraph is known from DE-37 16 434 C1.
  • this device has a separator in the form of a cylindrical jacket-shaped grate.
  • the central area of the conveying helix in the area of the separator is shaftless and continuous in the axial direction.
  • the conveyor spiral can be supported at its lower end.
  • Devices of this type in which the separator can be provided either in the form of a grate or else in the form of a sieve, are usually installed in the channel with an inclination angle of 30 to 35 °, in exceptional cases even up to 40 °. ie the axis of the screw conveyor forms this angle of inclination with the horizontal. The smaller this angle of inclination, the better the conveying effect of the screw conveyor. In the specified upper limit range, however, there is a risk that the screenings will rest on the conveyor helix and is conveyed by the rotating conveyor spiral on the spot in a circle without being lifted.
  • the slope of the conveying helix is also important.
  • the inclination of surface areas of the conveying helix located on different radii to a reference plane, for example the horizontal plane differs in such a way that they are further radially inward lying surface areas are steeper than the radially outer surface areas. Due to the angle of inclination with which the device is installed inclined in the channel, these angles are superimposed and there are different relationships depending on the radius.
  • the conveyor spiral can easily have surface areas on a relatively small radius, on which the screenings rests and are conveyed in a circle, while it slips further away on regions of the conveyor spiral in the direction of the inner wall of the housing.
  • the invention is based on the problem described and it aims to provide devices of the type described at the outset with standardized separator lengths and / or lengths which can optionally also be used at different channel depths and / or delivery heights.
  • the conveying helix is provided at least with a substantially radially inner region at an oblique angle to its axis in the region> 90 ° to 135 °.
  • the conveyor helix no longer extends - as seen in a cut through its axis - at an angle of 90 ° to its axis, but at a larger oblique angle in the specified range.
  • the conveyor helix is, as it were, arranged obliquely relative to its axis downwards or backwards, so that the individual surface areas of the conveyor helix which come into contact with the screenings assume a different position relative to the horizontal plane and thus to the direction of the action of gravity compared to the prior art.
  • This helix angle has the effect on the conveyor helix that the screenings slide more easily on the surface areas as a result of the other skew position with an unchanged angle of inclination or with an enlarged angle of inclination just slipped down and in both cases got more into the area of the inner wall of the housing.
  • the stationary wall of the housing can have a more proportional effect on the screenings compared to the rotating conveyor helix, whereby the conveying effect of the screw conveyor device is promoted or improved.
  • the comparatively improved or increased displacement of the screenings to a large radius that is to say in the vicinity of the inner wall of the housing, causes the screenings to come into frictional contact with the inner wall of the housing and is therefore prevented from spinning.
  • the screenings increasingly radially outwards, i.e. to a larger radius and thus in surface areas of the conveyor helix, which have a greater inclination than surface areas of the conveyor helix lying further inwards, so that the screenings do not remain on the conveyor helix, but in the direction of the Inner wall of the housing slides down on the conveyor spiral.
  • This makes it possible to be able to install the device into the channel with a steeper angle of inclination, with angles of inclination of up to 50 or 60 ° being achievable.
  • the same device can of course also be installed with an angle of inclination of approximately 30 to 35 ° and in all intermediate angles. This makes it possible to standardize the devices.
  • the device is installed with a larger angle of inclination than previously, the overall length of the screw conveyor device is advantageously shortened with the same channel depth and head.
  • the possibility of choosing a larger angle of inclination reduces the horizontal space requirement for the device.
  • Such devices are often surrounded by a housing, which of course is then also smaller and therefore less expensive to manufacture. there is even the possibility of being able to accommodate the device within a shaft with a large angle of inclination, that is to say particularly steep installation. In any case, the application range of the device is considerably improved.
  • the separator can still be designed unchanged in the form of a sieve or a grate.
  • the bearing area for the conveyor helix adjoining the separator, the conical transition area and the riser pipe area of the screw conveyor device can also be made unchanged in terms of their essential characteristics. It is possible to use the helix angle for the conveyor helix in the area of each inclined conveyor section, regardless of whether a separator is provided and how it is designed.
  • the invention can be applied not only to a separator and moreover not only in the area of the separator, but also continuously over the adjoining areas.
  • the critical area with regard to the conveying action in the area of the separator on the conveying helix is present at large angles of inclination, the application of the invention in this area is most important.
  • the helix angle to be selected depends on the angle of inclination to be used, in such a way that a larger helix angle must also be selected with a larger angle of inclination.
  • standardizations can be carried out and applied in the resulting areas.
  • the conveying helix can be provided, in particular in the area of the separator, with a slope of the order of magnitude of approximately 50 to 80 mm, whereas slopes of the order of 150 to 200 mm have previously been used.
  • a slope of the order of magnitude of approximately 50 to 80 mm
  • slopes of the order of 150 to 200 mm have previously been used.
  • the conveyor spiral can be arranged at an oblique angle of approximately 100 to 120 ° - in particular 115 °. Inclined angles that are too small, i.e. slightly larger than 90 °, only produce a relatively little improved conveying effect. If the oblique angles are too large, a wedge-shaped gap is created between the inner wall of the housing and the conveyor spiral, so that disadvantageous pinching of the screenings can occur.
  • the conveying helix can be designed without a shaft, in particular in the area of the separator, and continuously in the middle in the axial direction. This not only improves the hydraulic resistance in the area of the separator, it also removes the critical, internal areas of the shaft, thereby eliminating the risk of screenings rotating in these areas.
  • the conveyor helix can also be provided over its entire axial length with the oblique angle to its axis. This will be the case in particular when using large angles of inclination.
  • the screw conveyor device with its helical conveyor helix.
  • the shaping of the conveyor spiral in one gear while maintaining the oblique angle is comparatively complicated. But it has the advantage that there is no dead space and, in this respect, particularly small pitch angles can be applied.
  • the conveyor helix consists at least in some areas of a support helix and an obliquely placed filler plate. The support helix is arranged as it was previously the conveyor helix in the prior art, ie with an oblique angle of 90 °.
  • This second possibility also opens up the advantage of not arranging the filler plate continuously as far as the inner wall of the housing, but rather allowing it to end at a distance from the inner wall of the housing on the supporting spiral so that the end region of the effective conveying spiral forms a 90 ° angle on the Connects inner wall of the housing and thereby pinching the screenings in this area can be avoided.
  • the conveying spiral can have an outer region facing the inner wall of the housing with little or no inclined position.
  • the areas mentioned will generally have different extents, ie the outer area will extend over a much smaller diameter piece than the inner area. With this design, however, pockets are created, as it were, in the outer edge region of the conveyor helix, the screenings on the one hand finding sufficient steepness in the inner region for slipping, but jamming phenomena in the edge region of the conveyor helix are avoided.
  • a brush strip or a spray nozzle strip can be provided in the exposed area of the conveyor helix, which is set against the conveyor helix from the outside inwards at least over the range between the maximum and minimum water levels.
  • This brush strip or spray nozzle strip preferably extends axially over the separator, is arranged outside the circulation of the conveying spiral and extends with its bristles over with those emitted by the spray nozzles Water jets down to the surface of the conveyor spiral with which the screenings come into contact.
  • the brush strip or the spray nozzle strip have the function of preventing the screenings from being deposited on the conveyor spiral and from rotating. A certain build-up of dust or a wash-off effect occurs, as a result of which the screenings are in turn increasingly transferred to radially outer areas on the conveyor helix.
  • the outside area can be made substantially smaller than the obliquely arranged inside area. It is also possible to produce the conveying helix from a strip of material which has been bent in this regard and to work without a supporting helix.
  • the outside area can have a radial width of about 10 to 20 mm, while the inside area - depending on the size of the device - can have a radial width of 65 to 90 mm.
  • the conveying spiral In its lower region, the conveying spiral can be immersed in the liquid, exposed on the side facing the outflowing liquid and on the opposite side the cylindrical jacket-shaped separator in the form of a grate, sieve or the like, which extends to the bottom of the channel and is arranged parallel to the conveying spiral. be provided, along which the conveying helix removes the screenings, conveys them upwards and thus cleans the separator again and again.
  • the invention is applied throughout in the area of the separator and the subsequent conveyor line.
  • the invention can also be used only in the area of a conveyor line, the separator being designed according to DE-PS 30 19 127 or DE-PS 34 20 157 or DE-PS 36 30 755.
  • a channel 1 shown schematically in FIG. 1 the device is arranged with its axis 2 inclined. Axis 2 forms the angle of inclination ⁇ with the horizontal plane (FIG. 2).
  • the channel 1 has side walls 3, of which only one side is shown for reasons of clarity.
  • the device which is set obliquely into the channel, connects to the side walls 3 in the lower region with a separator 4. Possibly. there are corresponding transition covers (not shown).
  • the separator 4 can be designed as a grate (FIG. 1) or as a sieve (FIG. 2). In the area of the device there is a water level 5 which is due to the accumulation effect the separator 4 in front of the device is slightly higher than behind the device.
  • the channel 1 is flowed through in the direction of an arrow 6.
  • the separator 4 designed as a grate extends at least over such a height parallel to the axis 2 of the device that it can reliably perform its separating action even with changing water levels.
  • the separator 4 here consists essentially of grate bars 7, which are arranged parallel to the axis 2 on the surface line of a cylinder, and of support bars 8, which extend tangentially to the circumference of the cylinder of the grate bars and thus perpendicular to the axis 2 over a cylinder segment.
  • the separator 4 is open in the flow direction according to arrow 6. It is exposed on this side, so that the screenings and screenings separate out on the inner surface of the separator 4.
  • the separator 4 is, as it were, part of a housing 9 of a screw conveyor device 10.
  • the separator 4 is followed by a conical transition part 11 and then a riser pipe 12.
  • the screw conveyor device 10 has a shaft 13 which is equipped with a conveyor helix 14.
  • the conveying helix 14 also extends in the area of the separator 4. In this area, however, it is shaftless and has a continuous central passage in the axial direction in order to reduce the hydraulic resistance.
  • the conveyor helix 14 can be mounted with a bearing 15 in an end plate 16. However, it is also possible to dispense with the lower mounting of the conveyor helix 14 and to provide storage in the area of the housing 9 or the transition part 11.
  • the outer diameter and the inner diameter of the conveying helix 14 are adapted to the respective sections, that is to say to the separator 4, the transition part 11 and the riser pipe 12 and the shaft 13.
  • At the upper end of the housing 9 is another bearing, not shown here, for the shaft 13 or the conveyor helix 14 is provided.
  • a motor 17 and a transmission 18 are also arranged there, via which the shaft 13 and thus also the feed spiral 14 are driven.
  • the conveying helix 14 can have a constant or a variable slope over its axial length, so that, as shown, a compacting zone 19 is formed at the upper end of the conveying path, in the area of which the conveying helix 14 has a smaller slope than in the lower area.
  • the slope of the conveyor helix 14 is selected to be comparatively smaller, in particular in the area of the separator 4, than has been customary in the prior art.
  • the housing 9 is double-walled, the inner wall part having openings so that when compacting or compressing the screenings separated liquid can be directed back into the channel 1 via a pipe 20, while the compacted screenings 21 via a chute 22 is dropped into a container 23.
  • the essential peculiarity of the new device is that the conveyor helix 14 is arranged at an oblique angle ⁇ to its axis 2, as can be seen most clearly from FIGS. 3 and 4. These two representations show sections through the axis 2 and in the area of the separator 4, in which the screw conveyor 10 is designed to be shaft-free and axially continuous in the middle.
  • the helix angle ⁇ can also be used in other devices or device parts that form an upward conveying path, that is, for. B. the screw conveyor 10 can be applied.
  • the conveyor helix 14 is arranged in the prior art so that the cut cross section extends comparatively at an oblique angle of 90 ° to the axis 2, the conveyor helix 14 is now bent downwards so to speak that the helix angle ⁇ > 90 ° and in a range up to about 135 °, in particular in the range between 100 and 120 °, emotional.
  • the conditions in the area of the scraper 4 which can be designed as a sieve or as a grate, are shown here, the same conditions also apply in the other areas of the screw conveyor device, for example in the riser pipe 12.
  • the conveyor helix 14 only connects to the shaft 13 , but is otherwise identical, ie the helix angle ⁇ is also advantageously implemented in these areas.
  • the conveyor helix 14 consists of a passage which is shaped and arranged accordingly.
  • a support spiral 24 is provided.
  • This support helix 24 corresponds to the conveyor helix in the prior art, so that it can also be seen that the helix angle is 90 ° there.
  • a filler plate 25 is placed on this support spiral 24, specifically in an inclined position, that is to say at an oblique angle, this filler plate 25 essentially forming the effective surface which comes into contact with the screenings.
  • the outer edge of the filler plate 25 does not extend to the inner wall of the separator 4, but ends at a certain distance therefrom on the support helix 24.
  • the attachment can be carried out by a welding process at this point, which also creates a transition.
  • a dead space 26 which has no function and which is completely closed when a shaft 13 is arranged. But even in the case of a shaftless design, this dead space 26 can expediently be closed by tubular cut-out cladding parts (not shown), so that the filler plate 25 is supported at two points on the support spiral 24.
  • tubular cut-out cladding parts not shown
  • the effective surface areas of the conveyor helix 14 are positioned in such a position relative to the direction of gravity that the screenings on the conveyor helix 14 in the direction of the stripper 4 or the housing 9 slides down and thus does not rest on the conveyor helix 14, so that a rotation of the Screenings in a circular movement around axis 2 is avoided.
  • This is only possible up to a certain limit angle or limit range, depending on the inclined angle and also the slope of the conveying helix.
  • the angle of inclination ⁇ is chosen to be larger, that is to say the axis 2 of the device is installed even more steeply in the channel 1, the conveying effect disappears and the screenings also rotate without a conveying effect. This condition must be avoided under all circumstances. This is done by using the helix angle ⁇ , a small slope of the conveying helix 14, in particular in the range between 50 and 80 mm, being very beneficial. Through the additional use of this small slope, the usable angle of inclination ⁇ can be selected to be a few degrees larger than when using a slope in the order of 150 to 200 mm previously considered normal.
  • FIG. 1 show the conditions of examples of right-handed conveying coils 14, which also rotate clockwise, that is to say clockwise, from the side of their drive, that is to say the motor 17, so that the desired upward conveyance of the screenings occurs. It goes without saying that a left-handed feed screw 14 would have to be driven counterclockwise.
  • Figure 2 illustrates the essential advantage of the new device. While the devices with their axes 2 were previously installed at an angle of inclination ⁇ of the order of 35 ° in order to bridge the depth of the channel and the head with sufficient conveying effect, the new device can be at an angle of inclination ⁇ of up to approximately 50 to 60 °, that is to say essentially steeper, to be installed. It can be seen from the comparison of the two representations in FIG. 2 that the riser pipe length can now be chosen to be smaller, which results in considerable material savings. Furthermore, while maintaining the axial length of the separator 4, the maximum permissible water level increases, ie the The device can also be used when higher water levels have to be achieved.
  • the new device can not only be installed with the increased angle of inclination ⁇ in the order of 50 to 60 °, but of course also with smaller angles of inclination ⁇ .
  • the entire spanning area can thus be bridged and it is possible to standardize the devices in order to enable series production and not to redefine the axial length of the separator 4 on the one hand and the axial length in particular of the riser pipe 12 on the other hand for each individual application to have to.
  • FIG. 2 also shows that, following the separator 4, a storage area 27 for the conveying helix 14 can first be realized, to which the conical transition part 11 and then the riser pipe 12 are connected.
  • the bearing area 27 replaces a bearing 15 at the lower end of the device.
  • FIG. 5 shows a schematic representation of the new device with the helix angle ⁇ and the inclination angle ⁇ .
  • the separator is designed here as a sieve, which extends only over part of the circumference.
  • the conveyor helix 14 is exposed in the area of the separator 4.
  • the separator 4 merges with its wall here in funnel plates 28, which are provided so as to protrude radially outwards and connect to the side walls 3 of the channel 1.
  • An opening 29 is thus formed between the two funnel sheets 28.
  • a brush strip 30 is arranged outside the circumference of the conveyor helix 14 and can be supported on the one funnel plate 28.
  • the brush strip 30 has bristles 31, which are expediently arranged approximately radially inward from the axis 2 and thus protrude into the peripheral region of the conveyor helix 14. These bristles 31 have the task in the case of a clockwise driven conveyor helix 14 according to arrow 23 (FIG. 6), to stop or accumulate the screenings so that it does not rest on the conveyor helix 14 and is only conveyed in a circle. As a result of this accumulation, the screenings are released from the conveyor helix 14 and thus have the opportunity to slide down on the conveyor helix 14 in accordance with the respective inclination and in any case to get closer to the separator 4. This improves the funding effect.
  • a spray nozzle strip 33 which is indicated by dashed lines in FIG. 6, could also be provided in order to spray water jets onto the effective surfaces of the conveyor spiral 14 and thus to cause the screenings to move in the direction to move radially further outward areas of the conveyor helix 14 and thus in the direction of the separator 4. This can also support the funding effect. It goes without saying that it is important to arrange the brush strip 30 and / or the spray nozzle strip 33 at least axially in the area of the separator 4 in which the water level can move. This supports the particularly critical areas of the device with regard to a conveying effect.
  • FIG. 5 also shows that shear and guide strips 34 can be arranged on the inner wall of the housing 9 at least in the region of the riser pipe 12 and / or the compacting zone 19 in order to increase the friction on the inner wall of the closed housing by this additional measure and thereby favor the promotional effect on the screenings.
  • FIG. 7 shows a further device for removing screenings and / or screenings from liquid flowing in a channel, in which the invention is used in the area of the screw conveyor device 10, while the separator 4 is designed in another way independently of this is.
  • the screw conveyor device 10 extends into the interior of the separator 4 in order to take over the screenings separated and detached from the separator 4.
  • the shaft 13 of the screw conveyor device 10 also extends down into this area. It merges into a drive arm 35, via which the drive of the motor 17 is ultimately transmitted via the shaft 13 to a sieve grate 36, which is thus driven in rotation.
  • the sieve grid 36 can have a slot perforation 37. However, it is also possible to arrange grate bars driven in a rotating manner parallel to one another.
  • Baffles 38 can be provided on the inside of the sieve grate 36, which serve to convey the screenings or screenings deposited on the inner circumference of the sieve grate 36 upwards.
  • a detachment device 39 is provided, the wear-resistant brushes 40, for. B. in roll form, and / or spray water nozzles 41.
  • the detaching device 39 serves to release such screenings or screenings which do not fall off the inner circumference of the screen grid 36 solely due to gravity and to avoid clogging of the screen grid.
  • the separated material then falls into an insertion funnel 42 and is thus taken over by the screw conveyor device 10.
  • the conveyor helix 14 can have a different gradient over its length. In any case, it is provided with the helix angle ⁇ in the area of the separator 4, but preferably over its entire axial extent.
