Definitions

  • the invention relates to a device for removing separating material from liquid flowing in a channel, with an inclined, partially immersed in the liquid separating surface of a separating device and with a conveying device leading to a dispensing point outside the liquid for the separated material, which has a tubular housing a receiving opening for the material to be separated, has at least one driven screw conveyor and two adjoining conveying sections, one of which is arranged in the interior of the separating surface and merges into the other conveying section which transports the separating material out of the channel to the delivery point, the separating device and the Conveyor in a spatial assignment to each other.
  • This device is particularly in Sewage treatment plants can be used, but can also be used in other areas, for example in the textile industry, in slaughterhouses, poultry farms, tanneries, etc.
  • a device of the type described in the opening paragraph is known from DE 42 13 847 A1.
  • the screw conveyor fulfills a double function.
  • the screw conveyor is on the one hand part of the separation device and detaches the material to be separated separated on the separation surface.
  • the screw conveyor is part of the conveyor device by fulfilling the conveyor function.
  • the housing of the conveying device is firmly connected to parts of the separating device and is used, for example, to support a common drive for the separating device and the conveying device.
  • the axis of the separating device is arranged offset parallel to the axis of the conveying device.
  • the axis of the conveyor is arranged below the axis of the separator.
  • a common drive for the separating device and the conveying device is also provided, which makes a gear necessary if different speeds and / or directions of rotation are to be used.
  • there is also a structural connection between the separating device and the conveying device in that elements of the separating device are mounted on the housing of the conveying device.
  • DE 36 30 755 C2 shows a device in which the separating surface is formed as a collecting grate from a large number of ring disks, which is driven in rotation.
  • the separation surface is flowed through by the open end face facing the flow direction in the channel.
  • the material to be separated is deposited on the inside of the cylinder-shaped separation surface and is conveyed upwards as the separation surface rotates.
  • a clearing wiper is provided as a detaching device from the separating surface of the separating device, which at least partially engages in slots between the ring disks.
  • a conveyor for the material to be separated is provided with its axis, which is designed as a screw conveyor device and receives the separation material detached from the separation surface and conveys it diagonally upward in the direction of flow of the liquid in the channel.
  • the material to be separated is thrown off by the conveyor in the area of a delivery point.
  • the cylindrical jacket-shaped separation surface can be mounted on or on the housing of the conveyor.
  • a structural unit is formed from the separating surface or separating device and conveying device. This unit is installed at an angle in the channel, whereby the angle of inclination of the common axis to the horizontal can be varied within a certain range.
  • the separating surface which is designed here as a sieve grate, forms a structural unit with the conveyor device with a coaxial axis arrangement.
  • the separating surface is connected to the shaft of the screw conveyor device and is driven indirectly via it, so that only a single motor is required to drive the screen grate and the screw conveyor.
  • the previously known devices for removing material to be separated from liquid flowing in a channel are designed either with a stationary separating surface or with a rotating driven separating surface.
  • the separating surface does not have to extend in the shape of a cylinder jacket over the circumference, but it can also have an interruption point in the upper region.
  • the development direction in this field of devices is always based on the fact that the separating device with the separating surface on the one hand and the conveying device on the other hand is created as a related structural unit, whereby there is not only a spatial assignment of the parts, but the Individual parts are functionally and structurally connected. This is particularly the case with a coaxial design.
  • the conveying device is always arranged in such a way that it conveys the separated and absorbed material to be separated upwards in the direction of flow of the liquid and transfers it, for example, to a discharge point.
  • This has the advantage that the inflow surface of the cylindrical jacket-shaped separating surface is affected or blocked as little as possible by the conveying device.
  • the beginning of the conveyor with the opening for the material to be separated is at least large Part already arranged above the liquid level in the channel.
  • the disadvantage of these known devices is that there is a separate adaptation and design dependency of the individual parts with each other, whereby serial production is hindered. Even if devices are to be created for the same channel widths and different angles of attack and the same discharge height, the length of the conveyor necessarily varies.
  • the invention has for its object to provide a device of the type described in the introduction, in which the separating device with the separating surface on the one hand and the conveying device on the other hand are less dependent on one another, so that one and the same device with its individual structural units also in different inclined positions of the axes of the Separator and the conveyor and / or is largely universally applicable with regard to structural conditions.
  • this is achieved in a device of the type described in the introduction in that the separating device with the separating surface and the conveying device are two separate structural units which are also independent of one another in terms of drive.
  • the invention is based on the idea of at least constructively separating the separating surface or the separating device on the one hand and the conveying device on the other hand and only maintaining the spatial assignment between these two parts, as is the case for transferring or dropping off the separating material from the separating surface in the receiving opening of the conveyor is required.
  • the receiving opening of the conveying device which is often designed as an insertion funnel, only has to be arranged in spatial association with the separation surface in such a way that the material to be separated also comes into the funnel after it has been detached from the separation surface. This also eliminates the need for a coaxial design two separate units, and it suddenly becomes possible to separate the separator on the one hand and the conveyor on the other hand z. B. in series, produce and combine different units.
  • the inclined position of the axis of the separating device can be chosen completely freely from the inclined position of the axis of the conveying device, wherein in particular the advantages of an axial offset can also be used.
  • the new device is not only contrary to the well-established development path of such known devices. Different delivery heights can be bridged using the same units by changing the axis of the inclined position of the conveyor accordingly. This possibility of variation is of course limited by the geometry and inclined arrangement of the axis of the separating device. Since the arrangement of a driven screw conveyor can be omitted in the other, essentially upward conveying path, this part of the conveying device can consist of a simple pipeline, so that the discharge height can also be varied in a very simple manner here by extending or attaching a flange piece. This other conveyor line can lead approximately vertically upwards or inclined in a vertical arrangement to the axis of the one conveyor line.
  • the conveying section passing through the interior of the separating surface is arranged to convey the separating material in the channel against the direction of flow of the liquid.
  • This also creates a new generation of such devices, which differs from the previously known devices in that the conveying direction of the conveying device is, as it were, reversed; the conveying direction of the conveying device is no longer directed in the flow direction of the liquid in the channel, but in the opposite direction.
  • the conveyor must of course consist of two conveyor lines arranged at an angle to one another. Doing so one conveyor line essentially the horizontal transport of the material to be separated, while the other conveyor line is essentially assigned to the vertical transport.
  • Such a conveyor advantageously has a short radius in the direction of flow of the liquid in the channel. This also advantageously shortens the overall length of the device. This means that the new device can still be used in confined spaces.
  • the conveyor lines of the conveyor device can also be separate structural units, which, however, can be connected to one another.
  • the conveyor sections can be flanged to one another, in particular with the interposition of a pipe bend.
  • differently designed and prefabricated conveyor lines can be combined.
  • the spatial association between the separating device and the conveying device consists in that the receiving opening for the material to be separated is arranged below the separation area of the material to be separated from the separating surface in such a way that the material to be separated falls into the receiving opening. This avoids multiple deposition of parts of the material to be separated.
  • the housings of the two conveying sections of the conveying device can connect to one another at an angle of approximately 60 ° up to and including 90 °, a pipe bend, a T-piece, a branch or the like being provided between the housings of the two conveying sections. It is particularly easy to choose this angle at 90 °. It is even possible to arrange the one conveyor line not horizontally, but aligned horizontally, so that the other conveyor line then z. B. vertically upwards or can be arranged inclined to the side.
  • the assembly of the conveyor can also be installed with different inclinations relative to the separation device, depending on the inclination with which the axis of the separation device itself is to be arranged.
  • the Intermediate piece between the conveyor lines only requires a diameter adjustment to the housing of the two conveyor lines. Appropriate standardization is readily possible, so that the parts can be connected to one another via flanges.
  • the screw conveyor is provided at least in the area of the one conveyor section, i.e. in the part that essentially extends through the interior of the e.g. cylinder-shaped separation surface extends.
  • the conveying pressure on the material to be separated can be used to press the material to be separated upwards and to convey it in the other conveying section. There is a highly desirable compression effect of the material to be separated, and the residence time of the material to be separated is increased in the other conveyor section.
  • the axis of the one conveying path of the conveying device makes it possible for the axis of the one conveying path of the conveying device to be arranged eccentrically and / or at an angle to the axis of the separating surface.
  • the first conveying path of the conveying device can also be arranged, in particular, in an area above the axis of the separating device - in particular with a parallel axis arrangement - so that there is a comparatively lower discharge height for the material to be separated.
  • the conveying path extends deeper into the separating device, so that the overall length of the device in the direction of flow is shorter.
  • the possible inclined position of the conveying device - due to the angular axis arrangement - provides the additional advantage that the motor required for driving the screw conveyor is relatively above the liquid level can be arranged closer to the separator.
  • the conveying device extends forward against the direction of flow in the channel and through the liquid level. However, this only affects an insignificant part of the inflow surface of the separating device, so that there are no disadvantages for the separating function on the separating surface.
  • the motor for driving the screw conveyor of the one conveyor section can be placed on the end of the housing pointing in the flow direction in the channel, whereby a short construction in the flow direction can be realized.
  • a washing device can be provided for the discharged material to be separated, which has spray nozzles.
  • the spray nozzles for washing water can be arranged in the region of the insertion funnel of the receiving opening and also in the region of the bottom of the housing of the first conveyor line. This makes it possible to set the thrown-off material in motion and whirl it up, and thus to detach and shred organic substances from it, so that these organic substances remain in the liquid.
  • the material to be separated discharged by the conveyor is thus cleaner and can be further processed, for example deposited, more easily and without any unpleasant odors.
  • the housing of the first conveyor section which is required anyway, thus simultaneously forms the housing of the washing device.
  • the separation area also be driven in a rotating manner, in which case a stationary device for removing and transferring the material to be separated is provided to the conveying device.
  • the driven separating surface of the separating device can be cylindrical in shape, for example as a strainer basket or composed of rake bars.
  • the separating surface can also be formed by a link belt, sieve belt or the like, which is driven in rotation.
  • Such a polygonal separation surface can be advantageously adapted to the cross section of the channel, so that, for. B. with V-shaped channel cross-section so that the flow velocities at different water levels can be influenced.
  • the all-round driven separation surface with a polygonal cross section can have a plurality of links pivotably articulated to one another and can be guided over several rollers or rollers, it being sensible to design the links to be self-cleaning.
  • the links can have a hook shape and can have a self-cleaning effect due to the deflection on a roller or roller.
  • the other conveying section of the conveying device namely the conveying section, which essentially takes over the vertical transport of the material to be separated, can have an end region with a reduced diameter. In this way, a compression or compression point for the material to be separated is realized on the conveyor.
  • the screw conveyor In general, it is sufficient to provide the screw conveyor only for horizontal transport in the area of one conveyor line.
  • a conveyor screw is also provided in the other conveyor section of the conveyor device, which is driven by a motor arranged in the region of the delivery point.
  • the conveyor has two motors.
  • these can advantageously also be coordinated with one another at different time intervals are operated so that a targeted temporal drainage or compression of the material to be separated is possible.
  • the device according to FIGS. 1 and 2 has a separating surface 1 which is in the form of a cylinder jacket and which can be designed as a circumferential screen basket.
  • the separation surface 1 is arranged with its axis 2 inclined at an angle of approximately 25 ° in a channel 3.
  • the width of the channel 3 corresponds to the diameter of the separating surface 1.
  • the separating surface 1 can have at its upper end an at least partially closed end surface 4 and at its lower end an open end surface 5 through which the liquid loaded with the separable material flows in accordance with arrow 6.
  • the separating face 1 has an extension 7 which serves for the mounting and the attack of a drive with a motor 8.
  • the details of this drive with motor 8 are not shown here.
  • the training in detail is also of minor importance. It is important to recognize that a separator 9 is created as a separate structural unit with these parts, which can also be arranged with its axis 2 in the channel 3 at a different angle than shown.
  • a conveying device 10 is provided as a separate structural unit that is not structurally connected to the separator 9.
  • the conveyor device 10 has a first conveyor section 11 and a second conveyor section 12.
  • the conveyor section 11 has a housing 13 in which a screw conveyor 14 is provided on a shaft 15.
  • the shaft 15 or the screw conveyor 14 is driven by a motor 16 and possibly an intermediate reduction gear.
  • the motor 16 is placed on the housing 13 at the end of the conveying path 11 pointing in the direction of flow according to arrow 6 or flanged to the housing 13.
  • the housing 13 of this one conveying path 11 extends through the interior space 17 enclosed by the separating surface 1, facing forward in the channel 3 against the direction of flow of the liquid according to arrow 6.
  • the housing 13 has a receiving opening 18, which is usually funnel-shaped.
  • the material to be separated which is detached from the separation surface 1, is thrown into this receiving opening 18.
  • the conveying path 11 of the conveying device 10 with its receiving opening 18 must therefore be arranged relative to the separation point of the material to be separated on the separating surface 1 such that the material to be separated falls into the receiving opening 18.
  • openings, holes or the like are expediently provided above the water level, as is indicated in the drawing in FIG. 1.
  • the one conveyor line 11 with its axis 19 is so eccentrically displaced parallel to the axis 2 upwards that on the one hand a low discharge height of the material to be separated is achieved above the receiving opening and on the other hand the motor 16 is arranged short.
  • the conveyor section 11 thus has a small overall length in the direction of flow according to arrow 6. It essentially serves for the horizontal transport of the separated material to be separated.
  • the conveyor path 11 can also be arranged inclined.
  • the axes 2 and 19 can be provided concentrically, eccentrically or at an angle to one another. This leaves great variation possibilities.
  • the other conveyor section 12 is essentially intended for the vertical transport of the separated material to be separated. It has a housing 20 which is designed as a tube.
  • the housing 13 of the conveyor line 11 is connected to the housing 20 of the conveyor line 12 via a pipe bend 21, which here bridges an angle of 65 °.
  • the housing 20 merges into an ejection sheet 22, via which the material to be separated is dropped into a container 23.
  • the exemplary embodiment of the device according to FIGS. 3 and 4 is fundamentally similar to the exemplary embodiment of FIGS. 1 and 2, which is why reference can be made to the description in this regard.
  • Only the pipe bend 21 spans an angle of 90 ° here, so that the two conveyor lines 11 and 12 are provided at a mutual angle of 90 °.
  • the housing 20 of the conveyor section 12 can be arranged vertically or, as shown in FIG. 4, inclined laterally, depending on which discharge height is to be bridged for the material to be separated and which other conditions prevail. It can be seen in particular that axes 2 and 19 can be arranged at an angle to one another.
  • the separator 9 can also be designed in a completely different way.
  • the separating surface 1 can be driven circumferentially or arranged to be stationary. A circumferential detachment device would then have to be provided if necessary. If the separating surface 1 is driven in a rotating manner, a device 24 for removing and transferring the material to be separated to the conveying device 11 can be arranged to be stationary.
  • a device 24 can consist, for example, of a spray bar 25, which is indicated in FIG.
  • the conveyor section 12 can have a cone piece with reduced diameter, as a result of which a Compacting zone 26 is created. An additional compaction effect of the material to be separated can thus be achieved.
  • the embodiment of the device according to FIGS. 5 and 6 has the special feature that the conveyor sections 11 and 12 of the conveyor device 10 are connected to one another via a branch 27.
  • a shaft 28 with a screw conveyor 29 is also accommodated in the housing 20 of the second conveyor section 12.
  • the drive takes place via a motor 30 which is placed on top of the housing 20 of the second conveyor section 12. It is understood that the motors 16 and 30 can be operated in different, but coordinated time intervals.
  • the material to be separated is dropped here via a chute 31 (FIG. 6). It can be seen that the axes 2 and 19 are arranged offset parallel to one another. It can be seen from a comparison with the arrangement according to FIGS. 3 and 4 that, however, any other relative position between separator 9 or separating surface 1 on the one hand and conveying device 10 on the other can also be assumed within certain limits.
  • a pipe bend 21 is used which bridges an angle of 90 °. If the first conveying path 11 of the conveying device 10 is arranged with its axis 19 parallel to the axis 2 of the separator 9, the housing 20 of the conveying path 12 gets into a forward inclined position, which, however, only slightly reduces the discharge height in comparison to a vertical arrangement . If the discharge height is to be higher, then only the conveyor device 10 is erected comparatively more so that the axis 19 extends at an angle to the axis 2. A design change of the conveyor 10 is not necessary.

  • the polygonal shape of the separator 9 can be adapted to the cross-sectional shape of the channel 3 or vice versa. Due to the V-shaped design of the bottom of the channel 3 and the separator 9 in the lower region (not shown), a higher flow rate than in a channel 3 with a rectangular cross-section can be achieved even at low water levels.
  • a remaining cross section in the channel 3 can be closed on the inflow side into the separator 9 by means of sheets 34, the flow through the separator 9 from the inside to the outside.
