Definitions
- the invention relates to a retention device for cleaning a flowing medium as described in the preamble of claim 1.
- retention devices in flowing waters for cleaning particles are generally known as obliquely inserted, flat bar rakes which are provided with a discharge device for discharging the particles retained by the rake, which periodically remove the particles from the inlet or along of the rake to the surface and then a discharge device is available, such as Screw conveyors, spiral conveyors, belt conveyors to deposit the particles in landfills.
- a disadvantage of such systems is the high space requirement in order to achieve corresponding throughputs.
- the object of the invention is to provide a retention device which can be mounted as a compact unit in an existing channel and ensures a high throughput for the medium to be cleaned.
- the inflow of the liquid medium determining the channel feed is predetermined.
- a compact unit for medium to high throughputs is provided for the medium to be cleaned.
- a further advantage is, as stated in claim 6, that the large effective surface of the rake, with a comparatively small overall size, allows an increased throughput of liquid medium, the risk of laying on the rake surface being reduced.
- an embodiment according to claims 7 and 8 is also advantageous, as a result of which there is increased stability and robustness against vibrations, starting from the drive of the rake.
- a collection of the screenings pushed off the rake into the screenings chamber is collected for the discharge.
- an embodiment according to claim 12 is also advantageous in that the mixture of solid particles and liquid medium pushed into the screenings chamber is separated by the downstream screen.
- the tapering of the cross-section in the direction of the channel drain creates a pressure difference and the resulting suction effect in the area of the screenings chamber and on the rake, thus allowing good particle discharge with a high throughput.
- the setting of the inlet cross-sectional area can be changed.
- the configuration according to claim 19 specifies the direction of flow, which is guided in such a way that solid particles are prevented from being laid or accumulated in the edge region.
- devices of this size are particularly suitable for medium to large throughputs, but possibly also for smaller throughputs.
- a storage volume is formed which can also accommodate flow fluctuations, in particular a maximum flow.
- an embodiment according to claim 22 is also advantageous, as a result of which a flexible connection possibility is given.
- an embodiment according to claim 24 is also advantageous, as a result of which a simple adaptation of the drive is possible and no additional assembly effort is required.
- the advantageous development according to claim 25 forms a compact assembly.
- an embodiment according to claim 26 is also advantageous, whereby through such an arrangement the throughput can be increased n-fold and can thus be adapted to the corresponding field of application.
- FIG. 1 shows a cleaning device according to the invention and a discharge device necessary for the discharge of the retained particles, partially in side views;
- FIG. 3 the pot rake according to FIG. 2, cut in a side view and in an enlarged view; 4 shows a further embodiment variant of the cleaning device according to the invention;
- Fig. 5 shows an embodiment variant for the multiple arrangement of cleaning devices, in a highly simplified, schematic representation.
- the retention device 4 is a cleaning system for a flowing medium that flows in one direction - according to arrow 5 - and contaminants, in particular solid ones
- the retention device 4 is formed by a semi-tubular casing 7 inclined in the direction of the channel inlet 2, a cleaning device 8 and the in
- the retention device 4 consists of the throughflow openings 9 and the rake-shaped rolled-in rake bars 12, which run concentrically to one another at a distance 13 and form an approximately funnel-shaped imaginary surface 14.
- the funnel-shaped imaginary surface 14 results from the coordination of a continuously decreasing or increasing diameter 15 for the tire-shaped Chenre 12 and by the arrangement of the concentrically extending rake bars 12 with an offset 16 in the direction of a height 17 of the funnel-shaped arrangement.
- the number of rake bars 12 required for the retaining device 4 results from the main dimensions required for a specific throughput of the medium, in particular an inlet cross-sectional area 18, the height 17 and the cross-sectional dimensions of the rake bars 12 and the selected distances 13 between the rake bars 12 which determines the order of magnitude of the retained particles 6.
- the semi-tubular casing 7 for receiving the funnel-shaped retaining device 4 faces the channel drain 3, an inlet skirt 19 projecting above the height 17 and encompassing approximately half the circumference, which defines a maximum height 21 for the channel inlet 2 with an upper edge 20.
- the retaining device 4 facing the channel inlet 2 of the cleaning device 1 is operated by a drive 23 by an inner surface 22 which sweeps over it
- the rake 24 is formed, for example, by a sheet-metal cutting part 27, which is symmetrical to a central axis 28 of the drive shaft 25, which abuts the inner surface 22 of the retaining device 4, to retain particles 6 in a reversible rotational movement of a slot-shaped inlet opening 29 of the retaining device 4 in the direction of the channel drain 3 downstream tubular screenings 30 to feed.
- the C-shaped rake bars 12 with mutually facing end faces 31 are arranged at a distance 32 for receiving a cylindrical housing part 33, which forms the screenings chamber 30.
- the screened material chamber 30 projects with an as
- Sieve 34 in particular designed as a perforated plate - formed area in the jacket housing 7 and continues in the direction of the surface 22 with a guide tube 35 which, for discharging the retained particles 6 from the sieve chamber 30 e.g. a screw conveyor 36 of a helical conveyor 38 provided with a drive 37.
- a pipe drain 39 attaches to the jacket housing 7 to discharge the cleaned medium and is connected to the jacket housing 7 in a liquid-tight manner. eg welded to it.
- a diameter 40 of the flow cross section of the pipe outlet 39 is to be determined as a function of the inlet cross sectional area 18 of the cleaning device 8 for a maximum suction effect.
- the retention device 4 with the screenings chamber 30 and the casing 7 is shown.
- the jacket housing 7 located at a certain height 41 carries the retaining device 4 and the cleaning device 8. According to the throughput - depending on the field of application - the jacket housing 7 has a specific accumulation height 42.
- the liquid medium flows at a certain angle 43 in the direction of arrow 5
- Retention device 4 and generates an optimal flow in the cleaning device 1.
- An inclination angle 44 formed between the casing 7 and the upper edge 20 generates pressure minimization in the downstream area of the restraint device 4.
- the suction effect thereby triggered in the screenings chamber 30 enables the optimal separation of the particles 6 on the retaining device 4.
- the particles 6 are held in the screenings chamber 30 upstream of the channel drain 3 and are e.g. transported via the screw conveyor 36 to a downstream area, not shown.
