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 A1.
  • Mortar mixing pumps of the type mentioned serve for the fully automatic mixing of dry material such as ready-mixed mortar, cement and similar material, which is supplied primarily as bagged or in silos and must be mixed for use with water and optionally other additives. Mortar mixing pumps are used, for example, in tunneling.
  • the invention is therefore based on the object to provide a mortar mixing pump, which is less susceptible to deposits, therefore less cleaning effort requires and is generally easier to clean.
  • the screw conveyor which is to promote the material to be mixed in the mixing chamber, no longer arranged in a mixing tube, but in the lower part of a funnel for filling the material to be mixed.
  • the continuation of the funnel into the area around and under the auger improves its conveying capacity, in particular by equalizing the flow of material, because in this critical area now no disturbing edges and transitions between metal parts and a lining exist anymore. Dead zones and the resulting risk of formation of deposits, which could occur in the prior art mainly at the transition points between a hopper and the liner of a mixing tube, are on this Way avoided.
  • the funnel can be made in one piece or else in two parts, in particular with a transverse distribution.
  • the adjoining the hopper mixing chamber is ertindungsgemäfi a separate from the hopper and the pump flange, connected to the hopper component which is provided over its entire length with a lining of preferably polyurethane, polyethylene or silicone.
  • the lining can be produced by spraying the cylindrical mixing chamber or by inserting a corresponding, prefabricated molding. Such a molded part may also have on its side to be joined to metal a rubber layer which forms a composite with the polyurethane, polyethylene or silicone material and which is glued to the metal, for example.
  • the liner provides a very smooth and robust inner surface to which the material to be mixed practically does not adhere.
  • the lining is designed so that there is a smooth transition in the transition from the hopper to the mixing chamber.
  • the pump flange delimiting the mixing chamber at the pump end is preferably provided, on its side facing the mixing chamber, with a cover of polyurethane, polyethylene or silicone in the entire mortar-conducting region, 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 passage opening of the pump flange.
  • a plurality of liquid injection nozzles is further accommodated in a nozzle carrier, which is arranged in a recess of the lining at least approximately flush with the inner surface of the lining and releasably secured by fastening means accessible from outside the mixing chamber.
  • the mentioned features of the mortar mixing pump according to the invention significantly improve the operating behavior and maintainability.
  • the inventive arrangement of the liquid injection nozzles in a nozzle carrier allows in a simple manner to realize different injection angles.
  • Any desired configuration can be illustrated, for example, all fluid injectors may have different injection angles, as well as some of the fluid injectors may have the same injection angle, and of course all the fluid injectors may have the same injection angle. However, it will usually be preferred to provide at least two different injection angles in order to achieve a faster and more uniform moisture penetration of the material to be mixed.
  • the liquid injection nozzles may according to the invention be formed in the nozzle carrier itself, e.g. by a Senkerodiermaschine or by means of a laser, when the nozzle carrier is made of metal, or for example by molding when the nozzle carrier made of plastic, in particular polyurethane, polyethylene or silicone.
  • the liquid injection nozzles may be in the form of separate inserts carried by the nozzle carrier.
  • the nozzle carrier is preferably made of metal, in particular of stainless stainless steel, and the inserts are made 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 an embodiment the liquid injection nozzles of an insert each have the same injection angle. It is advantageous if the inserts are designed so that they can be used in two positions, which differ from each other by 180 ° in the nozzle carrier. It can then be realized with the same applications two different injection angle by an insert in one position and another use in the other position is inserted into the nozzle carrier.
  • a common feed line preferably supplies all liquid nozzle nozzles assigned to a nozzle carrier with liquid.
  • a distributor element is preferably connected between the end of the feed line and the nozzle carrier, which takes over the supply of liquid from the feed line to the individual liquid injection nozzles.
  • This distribution element may be, for example, a plastic molding whose material is chosen is that it also ensures a seal between the feed line and the outside of the mixing chamber.
  • the screw conveyor is provided with a sheath made of polyurethane, polyethylene or silicone in preferred embodiments.
  • the design can be such that the screw conveyor has only an inner shaft made of steel and the individual screw threads are completely formed of polyurethane, polyethylene or silicone.
  • a motor flange adjacent to the mixing chamber distal end of the screw conveyor is preferably provided on its side facing the funnel with a lining made of polyurethane, polyethylene or silicone.
  • This cladding has according to a preferred embodiment, a molded sealing lip for sealing against a screw driving the auger.
  • Figure 1 shows in a spatial representation obliquely from above a generally designated 10 mortar mixing pump, whose main components arranged in a hopper 12 screw conveyor 14, arranged on one side of the hopper 12 electric motor 16 for driving the screw conveyor 14, one on the opposite side of the hopper 12 arranged mixing chamber 18, a mixing chamber 18 at the funnel distal end limiting pump flange 20, and connected by means of the pump flange 20 with the mixing chamber 18 eccentric screw pump 22 are.
  • the funnel 12 is formed in two parts in the illustrated embodiment and comprises a reproduced in the figures, lower part and not shown in the figures, the upper part, which is opposite to the lower part and which serves to fill the mixing material to be mixed in the mortar mixing pump 10 ,
  • the upper hopper part can be removed for transporting the mortar mixing pump 10 to facilitate their handling.
  • a closure slide 30 is arranged in the upper region of the lower funnel part, with which the funnel-filling opening, in particular when the funnel upper part is removed during transport, can be closed.
  • the here two-part funnel 12 is preferably made of stainless steel.
  • the screw conveyor 14 is disposed in the lower part of the hopper 12 near the bottom thereof so as to convey the building material filled in the hopper 12 to the right as it turns out of the hopper into the mixing chamber 18.
  • the worm threads of the screw conveyor 14 are formed in the embodiment shown completely made of polyurethane and are part of a prefabricated polyurethane sheath 32, which is inserted or pressed into the steel shaft 26. As shown, the auger 14 does not only pass axially through the entire lower part of the funnel 12, but continues to settle into the mixing chamber 18.
  • the engine-end of the steel shaft 26 of the screw conveyor 14 is connected by a coupling 34 with a mixing member 36 which is rotationally driven by the screw conveyor 14 and for mixing the conveyed into the mixing chamber 18 building material with one or more liquids, eg with water, serves, which is supplied by means of a still to be described in more detail liquid injection device 38 of the mixing chamber 18 or become.
  • the mixing member 36 is provided with a series of circumferentially and axially spaced apart wings 40, which are mounted on a hollow cylindrical body 42 which is rotatably connected to a steel shaft 44 passing through it.
  • a stub 46 of a rotor 48 of the eccentric screw pump 22 extends into the mixing chamber 18 into it.
  • This stub 46 is rotatably connected by means of another coupling 50 with the adjacent end of the mixing member 36, so that upon rotation of the screw conveyor 14 and the mixing member 36 and the rotor 48 is set in rotational motion.
  • the two clutches 34 and 50 not only transmit said rotational movement but also act as hinges capable of absorbing the eccentricity occurring when the rotor 48 of the eccentric screw pump 22 rotates.
  • the eccentric screw pump 22 fastened to the pump flange 20 is of conventional construction and known function and will therefore not be explained further here. It also refrains from further describing the filling, conveying and mixing process taking place in the mortar mixing pump 10, since this is known to a person skilled in the art, e.g. from DE 38 09 661 A1.
  • the polyurethane lining 52 has a smooth inner surface and is provided on its outer side with a series of circumferential grooves 56, which for improved longitudinal elasticity of the Polyurethane lining 52 provide. As can be seen in particular from FIGS.
  • the polyurethane lining 52 is guided radially out of the mixing chamber 18 at the ends of the hollow cylinder 54 in order to achieve an improved sealing of the mixing chamber 18 both with respect to the funnel 12 and with respect to the pump flange 20.
  • the polyurethane liner 52 is provided on the end face of the radially extended portion facing the pump flange 20 with two integral annular sealing lips 58, 59 which further increase the quality of the seal to the pump flange 20.
  • the liquid injection device 38 is also constructed so that deposits in the mixing chamber 18 are avoided as far as possible in their area.
  • the liquid injection device 38 has a nozzle carrier 60, which in the exemplary embodiment shown is of elongate shape and is arranged in a corresponding recess 62 of the polyurethane lining 52 flush or at least approximately flush with the inner surface of the polyurethane lining 52.
  • the nozzle carrier 60 is in the described embodiment of stainless steel and has, as can be seen well in particular from Figure 3 and Figure 4, two inserts 64, in each of which two liquid injection nozzles 66 are formed, i. the liquid injection device 38 has four injection nozzles 66 in the illustrated embodiment.
  • the inserts 64 are made of polyurethane in the described embodiment, but may also be made of another suitable plastic or metal. According to a modified embodiment, not shown, the injection nozzles 66 may also be formed in the nozzle carrier 60 itself.
  • All injectors 66 may have the same injection angle. Preferably, however, the liquid injection nozzles 66 have different injection angles, in particular pairs of different injection angles, in order to achieve a more even and faster through-wetting of the material to be mixed in the mixing chamber 18.
  • the nozzle carrier 60 may include more than two inserts 64, that each insert 64 may include one or more injectors 66, that the injectors 66 of an insert 64 may have equal or different injection angles, and that if desired or required, even more nozzle carrier 60 may be provided.
  • the nozzle carrier 60 is held in the example shown by two countersunk screws 68, the shaft extends radially outwardly through the nozzle carrier 60, the polyurethane lining 52, the hollow cylinder 54, a distributor element 70 and a mounting flange 72.
  • corresponding thread bolts can be firmly attached to the nozzle carrier 60.
  • the mounting flange 72 is connected to the end of a feed line 74, is passed through the liquid to the liquid injection device 38.
  • the end of the feed line 74 opens into the distributor element 70 arranged between the fastening flange 72 and the hollow cylinder 54, which is formed inside, e.g. by appropriate channels or suitable recesses, that the liquid from the feed line 74 to the individual liquid injection nozzles 66 is fed through corresponding openings in the hollow cylinder 54 and the polyurethane liner 52.
  • the distributor element 70 provides a seal between the feed line 74 and the outside of the mixing chamber 18, more precisely its hollow cylinder 54.
  • the distributor element 70 is preferably made of a material such as rubber or plastic, e.g. Polyurethane, which is sufficiently elastic to ensure a good seal, and in which the required channels or recesses can be easily introduced.
  • the distributor element 70 is braced between the fastening flange 72 and the outside of the hollow cylinder 54.
  • the inserts 64 are to be removed, for example, to clean or replace them, only the nuts 76 need to be loosened, and then the nozzle carrier 60 with the inserts 64 can be removed inwardly.
  • the pump flange 20 is provided on its side facing the mixing chamber 18 throughout the material-carrying area with a cover 78 made of polyurethane, which is formed in the illustrated embodiment by a polyurethane molding 80, which in a central through hole the pump flange 20 is buttoned, through which also the stub 46 of the rotor 48 projects into the mixing chamber 18.
  • the polyurethane molding 80 is adapted to the shape of the through hole and designed so that it remains securely attached to the pump flange 20 after the Einknöpfvorgang. As can be seen in particular from FIG.
  • the polyurethane molded part 80 is pulled radially on both sides of the pump flange 20 so far outward in each case, that it comes into contact with the radially inner sealing lip 58 on the side facing the mixing chamber 18 and can serve as a seal between a stator 82 of the eccentric screw pump 22 and the pump flange 20 on the side facing the eccentric screw pump 22. As shown in FIG.
  • an annular section 84 of the polyurethane molded part 80 is received in the mixing chamber side in a corresponding recess of the pump flange 20, this recess extending radially outwardly only to the extent that the radially outer sealing lip 59 of the polyurethane lining 52 no longer engages with the annular section 84 but comes into contact with the metal of the pump flange 20.
  • the cover 78 can also be achieved by spraying PU material onto the pump flange 20 (not shown).
  • the area of the motor flange 28 is still protected in a special way against deposits.
  • the side of the motor flange 28 facing the funnel 12 is provided with a polyurethane covering 86, which on the one hand seals the motor flange 28 with respect to the outside of the funnel 12 and on the other hand by means of an integrally formed, obliquely inside the direction of the funnel 12 projecting annular sealing lip 88 provides a seal to the rotating engine clutch 24.
  • the polyurethane covering 86 is, apart from the molded-on sealing lip 88, an annular disc-shaped part, which is fastened for example in the manner of a bayonet lock on the motor flange 28. It provides an effective seal between the interior of the funnel 12 and the electric motor 16 and at the same time prevents unwanted material deposits from forming in this area.
