Definitions

• the present invention relates to a mortar mixing pump according to the preamble of claim 1.
• a mortar mixing pump is known from DE 38 09 661 AI.
• Mortar mixing pumps of the type mentioned are used for the fully automatic mixing of dry material such as ready-mixed mortar, cement and similar material, which is mainly supplied as sacked goods or in silos and must be mixed with water and, if necessary, other additives. Mortar mixing pumps are used, for example, in tunnel construction.
• the invention is therefore based on the object of specifying a mortar mixing pump which is less susceptible to deposits, therefore requires less cleaning effort and is overall easier to clean.
• the screw conveyor which is intended to convey the material to be mixed into the mixing chamber, is no longer arranged in a mixing tube, but in the lower part of a funnel for filling in the material to be mixed.
• the continuation of the funnel into the area around and below the screw conveyor improves its conveying capacity, in particular by making the material flow more uniform, because in this critical area there are no longer any disruptive edges and transitions between metal parts and a lining. Dead zones and the resulting danger of the formation of deposits, which could occur in the state of the art mainly at the transition points between a filling funnel and the lining of a mixing tube, are attributed to these Avoided way.
• the funnel can be made in one piece or in two parts, in particular with a transverse division.
• the mixing chamber adjoining the funnel is a component which is separate from the funnel and also from the pump flange and is connected to the funnel and is provided with a lining of preferably polyurethane, polyethylene or silicone over its entire length.
• the lining can be produced by spraying out the cylindrical mixing chamber or by inserting a corresponding, prefabricated molded part.
• Such a molded part can also have a rubber layer on its side to be connected to metal, which forms a composite with the polyurethane, polyethylene or silicone material and which is bonded, for example, to the metal.
• the lining provides a very smooth and robust inner surface to which the material to be mixed practically does not stick.
• the lining is preferably designed such that there is a stepless transition during the transition from the funnel to the mixing chamber.
• the pump flange delimiting the mixing chamber at the pump-side end is preferably provided on its side facing the mixing chamber with a cover made of polyurethane, polyethylene or silicone in the entire mortar-carrying area, which is in direct contact with the lining of the mixing chamber.
• the cover of the pump flange can also be produced, for example, by spraying polyurethane material onto the desired surfaces of the pump flange. Another possibility is to button a prefabricated molded part into a through opening of the pump flange.
• a plurality of liquid injection nozzles is furthermore accommodated in a nozzle carrier which is arranged in a recess in the lining at least approximately flush with the inner surface of the lining and is detachably fastened by fastening means accessible from outside the mixing chamber.
• this type of design considerably reduces the risk of deposits forming in the area of the liquid injection nozzles and, on the other hand, enables the liquid injection nozzles to be cleaned more easily by loosening the attachment of the nozzle holder from the outside and then removing the nozzle holder from the inside of the mixing chamber.
• the features mentioned of the mortar mixing pump according to the invention significantly improve the operating behavior and maintainability.
• the arrangement according to the invention of the liquid injection nozzles in a nozzle carrier makes it possible to implement different injection angles in a simple manner. Any desired configuration can be represented, for example, all liquid injection nozzles can have different injection angles, likewise some of the liquid injection nozzles can have the same injection angle and, of course, all liquid injection nozzles can also have the same injection angle. However, it will generally be preferred to provide at least two different injection angles in order to achieve a faster and more uniform wetting of the material to be mixed.
• the liquid injection nozzles can be formed in the nozzle carrier itself, e.g. by a die-sinking EDM process or by means of a laser if the nozzle holder is made of metal, or for example by molding if the nozzle holder is made of plastic, in particular polyurethane, polyethylene or silicone.
• the liquid injection nozzles can be designed in the form of separate inserts carried by the nozzle carrier.
• the nozzle carrier is preferably made of metal, in particular stainless steel, and the inserts consist of a plastic, in particular polyurethane, polyethylene or silicone.
• the inserts can also be made of metal.
• Each insert preferably comprises a plurality of liquid injection nozzles, wherein according to one embodiment the liquid injection nozzles of an insert each have the same injection angle. It is advantageous if the inserts are designed in such a way that they can be inserted into the nozzle holder in two positions that differ from one another by 180 °. It is then possible to implement two different injection angles with inserts of the same design, by inserting one insert in one position and a further insert in the other position in the nozzle holder.
• a common feed line supplies all liquid injection nozzles assigned to a nozzle holder with liquid.
• a distributor element is preferably connected between the end of the feed line and the nozzle carrier and takes over the supply of liquid from the feed line to the individual liquid injection nozzles.
• This distributor element can be, for example, a molded plastic part, the material of which is is chosen that it also provides a seal between the feed line and the outside of the mixing chamber.
• the screw conveyor is also provided with a coating made of polyurethane, polyethylene or silicone.
• the design can be such that the screw conveyor only has an inner shaft made of steel and the individual screw flights are made entirely of polyurethane, polyethylene or silicone.
• a motor flange adjacent to the end of the screw conveyor remote from the mixing chamber is preferably provided on its side facing the funnel with a covering made of polyurethane, polyethylene or silicone.
• this cladding has an integrally formed sealing lip for sealing against a shaft driving the screw conveyor.

• a stub 46 of a rotor 48 of the eccentric screw pump 22 extends into the mixing chamber 18 through the pump flange 20 delimiting the end of the mixing chamber 18 remote from the funnel.
• This stub 46 is connected in a rotationally fixed manner to the adjacent end of the mixing element 36 by means of a further coupling 50, so that when the screw conveyor 14 and the mixing element 36 are rotated, the rotor 48 is also set in rotation.
• the two clutches 34 and 50 not only transmit the aforementioned rotational movement, but also act as joints which are able to absorb the eccentricity that occurs when the rotor 48 of the eccentric screw pump 22 rotates.
• the eccentric screw pump 22 attached to the pump flange 20 is of conventional construction and has a known function and is therefore not explained further here. Likewise, there is no further description of the filling, conveying and mixing process taking place in the mortar mixing pump 10, since this is known to experts, e.g. from DE 38 09 661 AI.
