Sewage lifting device

The invention relates to a sewage lifting device, containing a device used for receiving the sewage Collecting space, at least one pump and connecting and connecting pipes -

In known sewage lifting devices, it is necessary to first place a concrete tub in the floor of the installation site to manufacture. A container serving as a waste water collection space and at least one are then placed in this concrete tub a pump to suck in and discharge the accumulated Built-in sewage. These built-in parts must generally be delivered individually and on site be mounted, which is very cumbersome and time-consuming and costly in general.

The invention is therefore based on the object of providing a sewage lifting device of the type mentioned at the beginning create through which assembly times and costs in particular can be reduced.

This object is achieved according to the invention in that the sewage lifting device is a prefabricated kit is designed, the waste water collection space and a pump space serving to accommodate the pump in one joint Plastic containers, separated from one another by a partition, are arranged next to one another.

This embodiment of the invention can the concrete tub, which was previously produced with relatively great effort, is completely eliminated and the entire sewage lifting device can be prefabricated as a ready-to-assemble kit in the factory, so that this kit only needs to be inserted into a correspondingly large excavated pit; a fitter then needs only the wastewater inlet to the wastewater collection room, the pressure line (for conveying the wastewater) and the ventilation and to connect the electrical lines, which in a relatively short time and thus with relatively little Assembly costs can be carried out.

A particular advantage of this sewage lifting device according to the invention can also be seen in the design of the container made of plastic. On the one hand, such a design has a relatively low overall weight _/ and the container can also be designed to be relatively weatherproof and acid-proof.

Further details of the invention emerge from the subclaims and from the following description some embodiments illustrated in the drawing. Show it

Fig. 4 is a similar plan view of the device

As in FIG. 2, but in an embodiment with two pumps arranged in the pump chamber.

With reference to Figures 1 and 2, a first embodiment of the invention will first be explained in its overall structure. The illustrated sewage lifting device 1 includes a container 2, which is essentially made of plastic, preferably glass fiber reinforced plastic is made. This container 2 is surrounded by a partition 3 (preferably made of the same plastic material) into a collecting space 4 serving to receive wastewater and a next to it arranged pump chamber 5 divided. This one for sewage collection room 4 and pump chamber 5 is common plastic container 2 - as in the consideration of Figures 1 and 2 becomes clear - cylindrical, so that it is particularly dimensionally stable, including the one provided at the upper end Container ceiling 2a contributes through its arched design.

In this first exemplary embodiment according to FIGS. 1 and 2, only one pump 6 (for example a centrifugal pump) is provided. This pump 6 is arranged in the vicinity of the container bottom 2b so that they with its longitudinal axis 7 is aligned approximately horizontally and approximately parallel to the partition 3, which in this case arranged as a flat wall approximately perpendicular in the container 2 and approximately parallel to the vertical central axis 8 of the container 2 is. In this way, the pump 6 can be accommodated in the pump chamber 5 in a very space-saving manner.

(§ ι II 1

From the intermediate wall 3, there is an inlet channel 9 in the lower container part and along the container circumferential wall 2c brought up to the suction opening 10 of the pump 6.

The pump 6 itself can be designed in the usual way and directly behind its suction opening 10 as well as immediately behind their pressure port each have a ball valve 11 of known design, wherein on the pressure-side ball valve 11 is connected to a conventional non-return valve 12 and a pressure pipe 13 to it can.

In the pump chamber 5, a diaphragm hand pump 14 is also arranged in a manner known per se, with the help of which in the If necessary, the pump chamber 5 can be pumped empty.

As can be seen from FIG. 1, a float device 15 can also be arranged in the waste water collecting space 4 be, via which, for example, the pump 6 can be switched on and off.

At the upper end of the container 2, i.e. on the container top 2a, an attachment is provided which is in the form of a Manhole is formed. This manhole

16 has a frame-like upper edge 17, which -

as is particularly clear in the detailed sectional view of FIG. 3 is expressed - designed to accommodate a cover grating 18 and designed to be adjustable in height (double arrow 19) is. This height adjustability of the upper edge

17 of the manhole 16 is through a telescopic The upper end of the manhole can be displaced in the direction of the double arrow 19. In this way there is a simplification in the assembly of the finished kit of the sewage lifting device in such a way, that the upper level of the manhole 16 by a simple height adjustment of the upper edge 17 to the

Floor level (e.g. concrete floor with screed) can be adjusted without making the container 2 cumbersome would have to be placed higher or lower.

Regarding the execution of the cylindrical container 2, it should also be said that it is made in one piece with its partition 3 can be and that the partition 3 has an access opening 20 approximately in the area of the upper end of the container (see e.g. Fig. 1) through which the sewage collecting space 4 can be climbed from the pump chamber 5, for example, for cleaning purposes. This entry opening 20 is with Sealed liquid-tight with the aid of a conventional cover 21 including a clamp and sealing elements. In the container circumferential wall 2c is also a wastewater inlet in the upper area and in the area of the wastewater collection space 4 22 is provided (see FIGS. 1 and 2); In addition, there is a conventional venting nozzle in the container top 2a 23 is provided for venting the waste water collection room 4. Finally, a lead-through nozzle can also be provided in the container top 2a 24 be arranged for electrical lines.

4 shows an embodiment of the sewage lifting device 1 'according to the invention, designed as a prefabricated kit, in which, in contrast to the first embodiment, two pumps 26 are provided in the pump chamber 5 ^{1 of} the container 2 ¹ are. The container 2 ¹ is generally again designed as a plastic container (in particular made of glass fiber reinforced plastic) and divided into a waste water collection space 4 'and the already mentioned pump space 5' by an intermediate wall 3 'which is arranged approximately vertically in the container and is integral with its side edges the container peripheral ^{wall 2c 1 is} connected.

9098 * 0/005 $

The two pumps 26 are located in a manner similar to the example in FIG. 1, just above the bottom of the container 2 'and symmetrically to one another. Here, the longitudinal axes 27 of the two pumps 26 are approximately horizontal and parallel to the container bottom, but aligned to one another at an angle ic £ which is slightly smaller than 90 ° in the example of FIG. In any case, the two pumps 26 are arranged in the container 2 'so that they are relatively close with their one long side on the peripheral wall 2c ^{1 of} the container 2', so that their longitudinal axes 27 - seen in the top view, that is, in the container cross-section - Form tendons to the container circumferential wall 2c ¹ , which is circular in cross section.

With the chosen, space-saving arrangement of the two pumps 26, it is then also expedient if the partition 3 ¹ - as can be clearly seen from the top view of FIG Is angled in the direction of the pump chamber 5 ', the suction openings 3O of the pumps 26 being flush with these angled intermediate wall edge regions 3'a and 3'b; In this way, the pumps 26 are aligned with their longitudinal axes 27 perpendicular to the associated angled partition wall edge regions 3'a and 3'b, and there is no need to provide a separate "inlet channel as in the first embodiment.

The other equipment parts of this second exemplary embodiment can be provided in exactly the same way as in the case of the reference 1 to 3 described embodiment, which is why some essential parts of the device in FIG with the same reference numerals as in Figures 1 to 3, but with the addition of a prime.
