- the required medium passes through a pressure pipe 20 through a fitting 21 m, the waste water discharge pipe 19.
- a mud slide 22 is arranged at the bottom of the container 17, this makes it easier for the deposited substances to be stirred up and kept in a swirling motion
- This arrangement has the advantage that it can be operated with very little switching on and off, ie the difference between the maximum (max) and the minimum (min 2) liquid level can be comparatively large. This is important in places where the primary aspect the fearful energy consumption is of course the system can also be operated with a low level difference (max - min 1) and frequent switching
- the solution shown in FIG. 3 is similar to that shown in FIG. 2, the difference is that the machine unit 1 is set upside down, ie the stirrer 4 is at the bottom and the pump 3 is at the top.
- This arrangement has the advantage that the stirrer is at the bottom. while suction is being carried out at the top. This means that the substances in the shaft that are dangerous for the pump, such as rubber, razor blades, rags, etc., cannot cause any damage to the pump.
- the part that contains the most fat is always extracted
- a further advantage of the arrangement is that the medium can also be stirred without the promotion of liquids.
- the solution shown enables the machine unit to be switched on at certain time intervals without wastewater being pumped out of the system dry state, and the periodic stirring up significantly speeds up the wastewater treatment process
- FIG. 4 shows a configuration of the machine unit according to the invention which differs from the conventional one
- FIG. 5 shows a fundamentally new form of the Ube ⁇ ump shaft, realized with the aid of this machine unit.
- FIG. 4 shows the machine unit 1 already shown in FIG. 1 in a horizontal arrangement, ie Sole 15 is installed parallel to the axis of rotation of machine unit 1.

- min 1 liquid level
- part of the blades of the stirrer 4 move in the air , and as a result, an intensive mixing of the wastewater with air is also achieved with this arrangement, it is possible to switch on and off at regular intervals regardless of the liquid level, which not only ensures that the medium is stirred, but at the same time that it is aerated In comparison with the previous systems, this is a fundamental novelty and an extraordinary advantage because the Ube ⁇ umpsystem already performs part of the wastewater treatment.
- the cleaning effect can be further increased by the injector 24 shown in FIG. 4.
- the injector 24 sucks in the medium on its widening side and prints it, accelerated by the Ruhrer 4, out on its narrower end and in this way produces, in addition to the ventilation, an extremely intensive flow of liquid.
- the ventilation effect can be increased even more when the injector 24 is turned on
- Air inlet pipe 25 is connected. This ensures that ventilation also takes place when the liquid is at the highest (max 2) level shown in FIG. 5, because the air inlet pipe 25 always protrudes beyond the liquid level and the introduction of air at every liquid level. ie an intensive mixing of waste water and air is guaranteed

- the stirring in this embodiment is generally softer and more uniform than in the other variants.
- FIG. 7 Also shown in FIG. 7 is an embodiment in which the shaft of the motor 2 is only extended in one direction, here the pump 3 is closer to the motor 2 and the stirrer 4 is attached to the stub shaft 7 further away from it.
- the stirrer 4 is a rotating basket 28, on the jacket and base of which there are ribs 29.
- the openings 30 formed in the jacket which at the same time form the feeding opening of the pump, filter the inflowing medium, so that the rotating basket 28 performs two functions at the same time: it stirs and filters the medium surrounding the machine unit 1.
- a further advantage is that the stirrer 4 keeps the lumpy material away from the baby's mouth, i. H. reduces the size of the particles flowing into the pump. This effect can be further enhanced by attaching 30 guide elements, for example inclined plates, to the front side of the openings when viewed in rotation.
- the casing of the rotating basket 28 can be cylindrical, but can also have a different, for example polygonal, cross-section.
- the machine unit is arranged in the shaft in the position reversed with respect to FIG. 7, pumping and stirring also take place here in the upper region of the medium and prevent the formation and adhesion of the fat layer to an increased extent.

- the pump 3 is not arranged directly on the base plate 31, but on an insert located on the base of the container 17. This insert is shown in Fig. 9.
- the insert 32 is essentially a container 33 provided with a cylindrical jacket, the inclined bottom plate of which is adapted to the bottom plate 31 of the container 17.
- the container 33 is provided with a handle 34, by means of which it can be inserted and removed.
- the base plate of the container 33 is provided with a cutout corresponding to the shape of the pump 3, so that the container 33 can be removed without having to move the pump 3.
- the inside of the jacket is provided with a roughened surface 35.
- the roughened surface can be of any design. Some examples are shown in Figures 10-14. Fig. 10 shows a file-like rough surface in section, Fig. 1 1 shows a sawtooth-like roughness. 12a, 12b and 13 illustrate surfaces roughened by perforation. The area depicted in FIG. 12 resembles a vegetable slicer in which the perforations are provided with cutting edges.
- FIG. 14 shows a surface roughened by hooks, the hooks having the same shape as the hooks of the so-called Velcro fasteners.
- the roughened surface can optionally be directly the inner surface of the container 17, but it is also possible to attach the roughened surfaces to special guide elements. It is apparent that the system shown in Figs. 8-14 other than those shown
- the pump used can be a simple liquid pump, a slurry pump or a grinding pump.
- a pump with a stirring disk is particularly preferably used in sewage shafts (FIG. 8). In this case, it is advisable to arrange the pump horizontally or on an inclined plane, the stirring disk pointing downwards in the latter case. However, it is also possible to arrange a pump of this type vertically, with the stirring disk located at the bottom.
- numerous other solutions can be used, depending on the local conditions and requirements
- the roughened surfaces can be attached to the container walls that delimit the water space, but also to guide elements or other elements or to the outer surfaces of the pump
- the system according to the invention works as follows
- the liquid to be treated or to be pumped generally enters the container discontinuously through the inflow opening.
- the pump between the maximum and the minimum level is actuated by a float switch.
- the one in the container is activated
- Liquid from the agitation disk is stirred intensively, and the stucco materials and impurities in the liquid are constantly crushed on the roughened surfaces. This leads to a homogenization of the liquid, a comminution of the coarse impurities, while the pump removes the liquid from the container
- the combinable device according to the invention guarantees numerous advantages in comparison with the conventional solutions.
- the stirring, pumping and, if appropriate, also the aeration of the medium can be carried out simultaneously any arrangement can be used, ie can be attached at one end of the motor or at both ends according to the requirements, and the entire machine unit can be operated with optimum efficiency both in the vertical and in the horizontal position
- the solution according to the invention thus ensures a machine unit or system which can be essentially assembled from module elements and which at the same time provides several functions with very good efficiency.
- the machine unit and the system containing it are self-cleaning, require practically no human intervention, are reliable, and their investment and operating costs are relatively small
- Use in wastewater treatment and drainage systems enables the wastewater to be pumped, over-pumped and partially cleaned at the same time. Stirring of the multi-phase medium in the collecting shaft prevents one of the phases from accumulating to an undesirable extent
- the machine unit containing the pump is not only put into operation when the specified level is reached, but the Ruhrer located in the machine unit can be switched on at regular intervals without the pump becoming defective the treatment of the wastewater in the shaft is decisively improved, since in this way the frequency of stirring and aeration does not depend on the speed of the wastewater supply, but can be stirred and aerated at regular intervals
- the solution according to the invention makes it possible for the first time that the wastewater is additionally intensively aerated during the regular or regular stirring and pumping For all these reasons, the machine unit according to the invention or the systems containing them is significantly more effective than the previous solutions of a similar character and ensures that economically operable systems are scanned.
