Definitions
- the invention relates to a device for cleaning wastewater according to the preamble of claim 1.
- Such a device is known from DE-OS-1 932 640.
- a horizontal agitator is arranged in a circulation tank, the propeller is surrounded by a piece of pipe.
- the diameter of the propeller corresponds approximately to the diameter of the pipe section, so that swirl losses are kept low ⁇ who and the flow generated by the propeller is directed.
- DE-OS-2 147 080 describes a similar Horizon ⁇ talrrocktechnik, in which the propeller is in turn surrounded by a piece of pipe.
- the generation of a circulating flow by means of conventional horizontal agitators requires a re ⁇ relatively high energy consumption.
- the object of the invention is to eliminate the disadvantages of the prior art.
- a device is to be specified with which a circulating flow in a treatment basin for purifying wastewater can be generated with reduced energy expenditure.
- the device should be as simple and inexpensive to produce.
- the size and depth of the forming depression depend on the geometry of the flow channel as well as the rotational speed of Hori ⁇ zontalrrockwerks.
- a suitable taper can of
- Cross-sectional area in the region of the horizontal agitator ⁇ be adjusted.
- the rejuvenation is relatively low and results arising from the volume of the trough to be avoided on the surface of the wastewater.
- the predetermined distance up to which the curvature extends upstream and downstream of the horizontal agitator is expediently the same.
- the distance results from the longitudinal extension of the trough.
- the cross-sectional area in the flow channel remain constant in a conventional manner.
- the two walls opposite each other expediently have a curvature in symmetrical design.
- at least one of the two walls bounded by the flow channel is a flow guide wall provided within the treatment tank.
- the flow channel can be defined by a treatment tank zende longitudinal wall and a provided within the treatment basin Strömungsleitwand be limited.
- a ⁇ Strö ⁇ flow duct having at least one agitator arranged therein horizontal is provided on both sides of the flow guide.
- each of the flow channels on the inventive design of the cross- sectional area .
- the proposed buckles / the wall / walls and / or floor may be prepared for example, by suitably shaped embarkop ⁇ as combinations or inserts in / on the wall / walls and / or floor of the flow channel.
- Such doublings or inserts can be made, for example, of fiber-reinforced plastic, stainless steel sheets or the like. be prepared. With the doublings or inserts, the first volume is provided.
- the flow channel during manufacture can also be designed so that therein the inventively proposed cross-sectional rejuvenation ⁇ is provided from the outset.
- its walls can be designed from the outset so that the tapering of the cross-sectional area according to the invention results.
- Fig. 1 is a plan view of a first arrangement
- FIG. 2 shows a partial plan view of a second arrangement.
- a rectangular treatment basin B is made up of two mutually opposite ones. ing longitudinal walls 1 and two transverse walls 2 formed.
- treatment tank B is a substantially parallel to the longitudinal walls 1 extending first Strömungsleitwand 3, as well as in the region of the ends of the first Strömungsleitwand 3 arranged second curved Strömungsleitassi 4.
- first Strömungsleitwand 3 and each of the longitudinal walls 1 je ⁇ Weils one Flow channel S formed in each of which Hori ⁇ zontalrrockwerk 5 is added.
- a flow direction SR generated by a propeller of the horizontal agitator 5 runs approximately parallel to the longitudinal extent of the flow channel S.
- a cross-sectional area of the flow channel S indicated by the reference Q decreases continuously from a distance A in the direction of the horizontal agitator 5.
- a minimum cross-sectional area Q is in the area of the horizontal agitator 5. More specifically, the propeller of the horizontal ⁇ agitator 5 in the area of the minimum cross-sectional area Q is arranged.
- the Verminde ⁇ tion of the cross-sectional area Q is formed by a directed towards the flow channel S buckle 6, which extends in each of the longitudinal walls 1 and the first flow guide. 3
- the bulges 6 are formed here symmetrically with respect to a median plane of the flow channel S.
- the curvatures 6 can be produced, for example, by means of suitably designed doublings, which are applied to the
- Inserts may also be provided which are inserted into recesses provided in the region of the longitudinal walls 1 and / or the flow guide wall 13.
- Such false edges or inserts for example, of glass ⁇ fiber reinforced plastic, stainless steel sheets or the like. be prepared.
- the function of the first arrangement is as follows:
- two horizontal agitators 5 are provided in a flow channel S formed between the first flow guide wall 3 and the first longitudinal ⁇ wall.
- Reference numeral 7 designates a further flow guide wall which divides the flow channel S into two further flow channels S1, S2. In this case, the further flow guide 7 is substantially parallel to
