Definitions
- the present invention relates to a channel washer with a collecting space for Flushing liquid, which has a flushing opening towards the channel to be flushed, one Flood space, which is connected to the collecting space via a flood space opening, and a closure body, the flush opening and the Closes the flood space opening and the two openings when the flood space floods releases.
- sewer flushers are usually used for sanitary or sewerage automatically, preferably using collected surface water, to wash.
- the sewer networks in settlement areas are increasing geared towards separation drainage. Be through the sewage network only the heavily polluted waste water is sent to the sewage treatment plant. The rain water should seep away as possible or be fed directly to the natural river become.
- the sewer network is flushed mainly with mobile cleaning devices performed and is therefore expensive and unsanitary.
- direct connection of a gutter drain or one Street drain on the sewage channel does not bring the desired Success because of the rainwater inflow that occurs through the precipitation there is no strong washing power.
- Such small flushing drains which in particular with the frequently occurring small rains with low intensity, distribute act quickly and - if at all - only over a short distance.
- the washing liquid can first be in one Collection space can be collected until a larger amount of flushing fluid has accumulated which is then gushing into the channel to be rinsed with great washing power is drained.
- DE-PS-21 81 85 is a channel washer of the aforementioned Kind known.
- this well-known channel washer is in several ways insufficient, in particular the washing power is due to the limited cross-sectional area inhibited the flushing opening. In addition, there is a risk that can contaminate and clog the flushing opening or the flood chamber opening and as a result, the safe functioning of the sewer cleaner is no longer guaranteed.
- the present invention is therefore based on the object of improving To create channel washer of the type mentioned that of the prior art avoids known disadvantages.
- a channel washer should be created which is safe with little maintenance and the hydraulically more effective is.
- the flushing opening is arranged in the flood space.
- the collecting space is connected to the flushing opening through the flood space opening.
- the outflowing rinsing liquid flows out of the Collecting space through the flood space opening and a section of the flood space, to flow through the flushing opening into the channel to be flushed.
- the rinsing opening is preferably in a bottom region at the lowest point of the Flood area arranged. This can cause contaminants that occur during a flushing liquid supply in the form of rainwater inevitably in the collection room of the sewer washer and deposited there on the sole, be flushed out into the dirty water channel via the rinsing process. At the same time, the flushing power is due to the hydraulically favorable arrangement of the Rinsing opening in the bottom area of the sewer washer increased.
- the flood space has Rinse opening towards a continuous gradient.
- the flood area has none knee-like or U-shaped sections in which rinsing liquid remains would and get contaminants, dirt or solids and the like could deposit.
- the flood space is thus towards the flush opening without a low point flushed freely.
- the collecting space and the flood space towards the flushing opening are preferably funnel-shaped educated.
- the Flood space, the collecting space and the arrangement of the flood space opening and the Flush opening be designed such that the outlet flows of the flood space and the collecting space after the openings have been opened by the closure body are essentially rectified. Through the rectified outlet flows a particularly powerful flushing surge is created, which Deposits and dirt on the channels to be rinsed away.
- the valve seat of the closure body i.e. the corresponding areas in the area the flushing opening and the flood space opening, against which the closure body rests, is freely consistent according to the invention and does not form any resistance to adhesion of contaminants.
- the flushing opening and the flood chamber opening free of edges and walls directed against the discharge flow.
- the edges and walls in the area of the flushing opening and flood chamber opening or tangents to these are designed and aligned such that the impinging Flushing flow always has a component pointing to the drain. hereby a computational effect, as is the case with known channel flushers, is eliminated.
- the outlet flow is not directed against edges and walls, so that in particular fiber-containing impurities do not get stuck anywhere can interfere with the breech valve seat, resulting in failure the device would lead.
- the invention provides an overflow from the collecting space into the flood space.
- the incoming rinsing liquid runs into the flood area over and floods this, thereby also on the closure body from the flood space a water pressure acts here, which floats it, so that the flushing opening is released.
- the control of the rinsing process works automatically and automatically.
- the rinsing process is triggered without external energy.
- the flood area be separated from the collecting space by a barrier wall open at the top, so that the rinsing liquid at the appropriate liquid level in the collecting space overflows over the barrier wall and floods the flood space.
- the overflow can also have a closure that is dependent on the flushing liquid level is controlled in the collection room.
- a closure that is dependent on the flushing liquid level is controlled in the collection room.
- the channel washer shown in Figures 1 and 2 has a collecting space 1, the Can be filled with rinsing liquid via at least one inlet opening 2 and via one Rinsing opening 3 can be emptied through which the rinsing liquid into the channel to be rinsed or flows into the sewer system to be flushed
- the flood space opening 5 is substantially above that in the bottom area or in Bottom 9 of the collecting space 1 or the flood space 6 arranged rinsing opening 3.
- the flood space opening 5 is arranged obliquely according to FIG. 1. 1 shows the flood space opening 5 in a plane that slopes over in the manner of a roof the rinsing opening 3 extends.
- the flood space opening 5 is arranged such that the flushing liquid flowing down through the flood space opening 5 directly into the rinsing opening 3 flows.
- the flood space opening 5 is several times larger than the flushing opening 3, so that a streamlined transition from the collecting room 1 to flood space 6 and so that arises towards the rinsing opening 3.
- the walls of the sole area 9 are around the rinsing opening 3 around it in a funnel shape, inclined towards it, in order to allow it to flow away more easily the washing liquid and to achieve a strong washing power.
- the flood space 6 is completely above, i.e. at a higher level than the flush opening 3, i.e. the the walls delimiting the flood space 6 have a continuous gradient the flushing opening 3 so that the accumulated therein after flooding the flood space 6 Flushing liquid entirely from the flood space through the flushing opening 3 expires.
- the flood space 6 and the collecting space 1 with the respective Openings designed such that the outflow flows from both rooms are directed essentially the same. In contrast to the state of the art known solutions, the flow from the flood space 6 does not hinder the discharge flow from the collecting room 1.
- a floating closure body closes 7 due to its own weight with its contour fluid-tight on the one hand the flushing opening 3 and on the other hand the flood chamber opening 5 in the barrier wall 4, so that during the filling of the collecting space 1 with rinsing fluid no liquid from the Collecting space 1 can penetrate into the flood space 6 or into the flushing opening 3.
- the closure body 7 is preferably designed as a ball, the rinsing opening 3 and the flood space opening 5 are correspondingly circular, so that they rest on a spherical segment of the closure body 7 and sealed by this can be. 1 shows, the flood space opening 5 is dimensioned such that the spherical closure body 7 up to close to its maximum Diameter can dip into the flood space opening 5 and closes it. In contrast, the rinsing opening 3 is made smaller, so that it is one smaller spherical segment of the closure body 7 can be closed.
- the rinsing liquid collected in the collecting space 1 rises above a defined liquid level 8
- the rinsing liquid passes through an overflow 10, i.e. in the example shown via the barrier wall 4 open at the top, in the initially empty Flood space 6, floods it and washed around the closure body 7 in the lateral surfaces between the upper sealing seat of the flood space opening 5 and the lower Sealing seat of the flushing opening 3.
- the liquid collected in the collecting space 1 and in the flood space 6 can thus suddenly escape into the sewage system via the flushing opening 3, thereby an abrupt rinse with high rinsing power is automatically brought about.
- the dashed representation of the closure body 7 according to Figures 1 and 2 shows this in the floating state.
- the closure body 7 is freely movable in the collecting space 1. hereby can achieve a particularly compact design of the channel washer and This can also be used in confined spaces.
- Fig. 3 shows a further embodiment of the channel washer, which differs from the Channel washer described above according to Figures 1 and 2 mainly by the design of the closure body 7 differs.
- the closure body 7 measured Figure 3 has a generally spherical purging port seal 7A and a separate flood space shutter 7B, which is in the form of a polyhedron has, wherein it widens from its side facing the rinsing opening 3 Has flanks so that it plunge into the flood space opening 5 in the manner of a cone and can seal them with the inclined flank surfaces (see Fig. 3).
- the purge opening seal 7A and the flood space opening seal 7B are together coupled, as Fig. 3 shows rigidly connected to each other via a rod.
- the multi-part closure body 7 is overall, i.e. its two sections 7A and 7B together, in contrast to the embodiment according to FIGS. 1 and 2 in the collecting space 1 not freely movable, but along a guide 11 guided.
- the guide 11 is designed as a swivel guide and has one Swivel arm 19, at one end of the closure body 7, in particular the Flood space opening closure 7B is attached. With its other end is the arm 19 pivotally hinged, and preferably about an axis in the plane lies in which the flood space opening 5 also lies. As shown in Fig.
- the closure body 7 can be between its closed position, in which both the flood space opening 5 and the flushing opening 3 are closed and an open position in which the two openings are released, be pivoted.
- the flood space closure 7B serves as a float, so that the closure body 7 when the flood space 6 floods, as described above, floats (dashed position in Fig. 3) and releases the openings.
- the barrier wall 4 or the flood space opening 5 With the guided in the collecting room 1 and formed as shown multi-part Closure body 7, it is possible to the barrier wall 4 or the flood space opening 5 to be arranged at a greater distance from the rinsing opening 3. In addition, through the guide 11 of the closure body always securely and precisely in its openings 3 and 5 closing position moved back when the rinsing process takes place and the collecting room 1 is empty.
- Figures 4 and 5 show a further embodiment of an inventive Sewer cleaner installed in a sewer shaft.
- the flood space 6 is formed by a curved overflow pipe, the wall of which 4 serves as a barrier to the collecting space 1.
- the closure body 7 is similar to the embodiment according to Figures 1 and 2 spherical. in the In contrast to the first embodiment, the flood space opening 5 is horizontal arranged and runs at a defined distance parallel to the flushing opening 3. As Fig. 4 shows, the flood space opening 5 is immediately perpendicular above the flushing opening 3, see above that the rinsing liquid stored in the collecting space 1 is vertical with maximum Acceleration can flow through the flush opening.
- the flood space 6 is sufficient in the area of the flushing opening 3 and the flood space opening 5 large that the flushing liquid penetrating into the flood chamber 6 Closure body 7 in the area between the seats, which are from the edges of the Flushing opening 3 and the flood chamber opening 5 are formed completely by the Flushing liquid can be washed around (see. Fig. 4).
- the flood space 6 surrounds the closure body 7, when it is in its closed position, annular.
