Definitions

  • the invention relates to a device for the on-site production of pumpable mortar compositions, consisting of a screw mixing device which can be supplied with a metered amount of water continuously via a filling hopper dry material and a connecting piece following the feeding hopper in the conveying direction, and from a screw pump connected downstream of the screw mixing device.
  • the screw mixing device comprises several mixing zones, namely a screw mixer arranged coaxially with the screw pump, which is driven together with the screw pump, and above and parallel to this unit, a screw conveyor working in opposite directions, between its inlet opening, which can be filled with dry mortar, and its one below arranged unit connected outlet opening has a worm member, which consists of the succession of a screw conveyor, a metering screw and a There is a premix screw on a common shaft.
  • the device described primarily provides liquid screed with a consistent consistency. If, however, plaster or masonry mortar, which is much thicker than liquid screed, is to be produced with this device, in addition to replacing the screw pump with a correspondingly more powerful unit, further conversions are required, namely an exchange of all upstream mixing elements for other types.
  • the invention has for its object to simplify the device of the type specified in the introduction and its conversion from the production of self-leveling screed to the production of plaster and masonry mortar and vice versa.
  • the screw mixing device and the screw pump are arranged coaxially one behind the other along an axis falling in the conveying direction, which includes an angle with the horizontal between 10 ° and 30 °, that the screw mixing device and the screw pump have a common drive unit and that the mixing element of the screw mixing device comprises only two sections, of which the first section is essentially designed for conveying the dry material added as dry mortar to the water connection piece and the second section for mixing the dry mortar with the water.
  • the proposed device is therefore much simpler in construction than the device of the type specified in the introduction.
  • a single (gear) drive motor is sufficient for mixing and pumping.
  • the retrofitting of the device from the production of self-leveling screed to the production of plaster and masonry mortar (and vice versa) is considerably simplified.
  • only the single mixing element needs to be replaced.
  • the proposed device is particularly easy to transport because of its simple structure.
  • the mixing element runs at a speed of 150 to 300 rpm and the screw pump delivers 70 to 100 liters of mortar mass per minute.
  • the embodiment according to claim 3 achieves a particularly uniform loading of the mixing element with the dry mortar and thereby improves the mixing quality.
  • the embodiment according to claim 4 relates to the design of the mixing element for the production of spray plaster (or masonry mortar).
  • the embodiment according to claim 5 relates to the design of the mixing element for the production of liquid screed which is considerably thinner in comparison to plaster or masonry mortar.
  • the device according to claims 1 to 5 requires ready-to-use dry material premixed with sand, which comes, for example, from a silo installed on the construction site, under the outlet of which the device with its filling funnel is positioned. Because of the transport costs, among other things, this is delivered ready-to-use, consisting of approximately 50% sand Dry material is more expensive than mortar masses produced on site in the same ratio of sand and binding agent (e.g. recipes based on cement and / or anhydrite).
  • the invention is therefore based on the further object of improving the proposed device to the effect that it can optionally also be used to produce pumpable mortar compositions, in particular liquid screed, from dry binder and sand added separately therefrom.
  • the screw mixing device and the screw pump are arranged coaxially one behind the other along an axis falling in the conveying direction, which includes an angle between 10 ° and 30 ° with the horizontal, that the screw mixing device and the screw pump have a common drive unit, that the mixing element of the screw mixing device comprises two sections, the first section of which is essentially designed for conveying the dry material added as a binder up to the water connection socket and the second section for mixing the binder with the water, and that the screw mixing device at the level of the second section of its mixing element has an opening on its upper side in its tubular jacket for loading with sand.
  • This device can be further configured in the same manner as indicated above with reference to claims 2 to 5 for the device according to claim 1.
  • the mixing device is particularly suitable for the production of self-leveling screed from binder, water and subsequently introduced into the mixing zone Sand is suitable. Accordingly, the mixing device according to claim 5 is preferred.
  • This inventive improvement of the device explained above, which works with dry material premixed with dry material, is based on the knowledge that when the throughput (the delivery rate) of the screw pump is greater than the delivery rate of the upstream mixing device, the mixing zone is only partially filled with material.
  • the mixing zone thus contains air-filled cavities, often in the form of separate air cushions, which can be filled to a certain extent with the required amount of sand. It is surprising that a homogeneous, pumpable mortar mass can be produced in this way despite the very short mixing section.
  • the air cavities required for feeding the sand can be created by replacing the worm pump produced from dry mortar and water with a given drive speed of the common shaft of the worm mixing device and the worm pump for such a higher delivery rate.
  • the above-mentioned effect occurs, for example, at a speed of 200 rpm, so that an increase in the speed above this value leads to the desired air cushions in the binder / water mixture.
  • a sand feed hopper is arranged above the sand loading opening provided in the casing of the screw mixing device.
  • the sand feed hopper has a tubular funnel neck and that a sand conveyor screw is provided in the funnel neck, which can be driven by means of a gear motor arranged above the sand feed hopper.
  • a sand scraper following the course of the inner wall of the funnel or another stirring element can be combined with the sand screw conveyor, which ensures that the possibly moist sand sags evenly.
  • the speed of the screw conveyor is determined so that it has the desired mixing ratio, e.g. 1: 1, from binder to sand.
  • the sand feed hopper can be used in any way, e.g. can also be kept automatically from a silo using fill level sensors known per se in the funnel filled with sand.
  • a simpler option is specified in claim 9 and provides that a metering conveyor belt for the sand ends at the inlet opening of the sand feed hopper. Suitable metering conveyor belts are known per se.
  • On the feed side you have a shaft into which the sand e.g. is shoveled. The amount of sand transported away from the belt running at a constant speed per unit of time can be adjusted via a gap which can be adjusted.
  • the discharge end of the metering conveyor belt connectable to the sand filling funnel.
  • the sand feed hopper is arranged with a vertical central axis is and carries a bracket rotatable about its central axis for the discharge end of the metering conveyor belt, on which the gear motor for the sand conveyor screw is also mounted. The holder can thus be brought into the position depending on the local conditions in which the metering conveyor belt is located.
  • the funnel-shaped outlet 1 of a dry mortar silo which is otherwise not shown, is connected via an elastic intermediate piece 2, for example a short hose section or an elastic bellows, to an opening in the lid 3a of a filling funnel 3, which opens into a screw mixing device 4 .
  • the screw mixing device 4 contains a mixing element 5, which is shown in FIG. 2, but is optional can also be exchanged for the mixing element 9 shown in FIG. 3.
  • the mixing element 5 can be driven by means of an electric motor 6, which is only indicated schematically, with a transmission 6a connected at a constant speed of a few hundred revolutions per minute.
  • a screw pump 7 of known type is flanged, the screw conveyor of which is non-rotatably connected to the mixing element 5.
  • the screw pump 7 conveys in the direction of a pipe or hose 8 leading to the place of use.
  • the screw mixing device 4 and the screw pump 7 are therefore arranged coaxially one behind the other along an axis falling in the conveying direction, which includes an angle ⁇ between 10 ° and 30 ° with the horizontal.
  • the device is mounted on a chassis 10, which is only indicated symbolically.
  • the elastic intermediate piece 2 is released either from the silo outlet 1 or from the shaft 3.
  • the hopper 3 has a wall 3b which acts as a slide.
  • This wall 3b which runs essentially transversely to the conveying direction and is adjacent to the motor 6, therefore encloses an angle ⁇ with the vertical, for example in the range from 30 ° to 50 °.
  • the filling opening in the lid 3a of the funnel 3 is located above the wall 3b, so that the dry mortar first meets the wall 3b from above and then slides downwards into the screw mixing device 4.
  • the mixing element 5 is first conveyed by the mixing element 5 in the direction of a water inlet symbolized by a connecting piece 11, then mixed thoroughly with water and supplied to the screw pump 7 partly under the influence of the mixing element 5 and partly under the influence of gravity. Meanwhile, over the water connection piece 11 and a symbolically illustrated line 12 water from a metering device 13 continuously fed in metered amount.
  • the metering device 13 which can be of any known type, is connected to the local water network via a solenoid valve 14, which can also be designed as a pressure reducing valve.
  • an electrical control cabinet 15 which controls the entire device, in particular as a function of the output signal of a level detector 16 arranged at or in the hopper 3 at a suitable location.
  • a level detector 16 arranged at or in the hopper 3 at a suitable location.
  • the level indicator 16 can e.g. trigger the activation of a vibrator in the silo above or the opening of a slide at the silo outlet if the specified fill level is undershot.
  • the device according to FIG. 1 can be used to produce plaster or masonry mortar as well as liquid screed. This is achieved through the use of specially designed mixing elements which are adapted to the respective material and which are very easily interchangeable, together with the replacement of the screw pump 7 which is necessary in any case and which, in the case of the production of plaster or masonry mortar, must be considerably more efficient than in the case of the production of self-leveling screed, since the latter has a thinner consistency than, for example, spray plaster.
  • the drive unit consisting of the electric motor 6 and the gear 6a is pivotally connected to the housing of the screw mixing device 4 (not shown).
  • the mixing element 5 shown in Figures 1 and 2 is used to produce plaster or masonry mortar.
  • it comprises a first section 51 made of a continuous screw 50 with approximately 31 ⁇ 2 turns and a second section 52 of approximately the same length made up of segments 53 of a screw with a larger pitch than the first mentioned screw.
  • a particularly good mixing effect is achieved due to the relatively large pitch of the screw segments 53 of the second section 52.
  • the preferably periodic gaps 54 prevent this large slope from causing a correspondingly high conveying speed in the axial direction. If the conveying speed is too high, the mixing time would be too short to achieve homogeneous mixing.
  • an axial web 55 which connects the peripheral edges of axially successive segments 53 and forms a wall scraper.
  • the first section 51 corresponds essentially to the dry area of the screw mixing device 4
  • the second section 52 corresponds to the wet area.
  • the mixing element 9 shown in FIG. 3, on the other hand, is used to produce liquid screed. It also includes two functionally different sections.
  • the first section 51 has individual, flat mixing vanes 90, which are each set against the radial plane around an angle (which, as in the case of FIG. 2, runs from right to left) and the desired conveying speed.
  • This is followed by the second section 92, which corresponds to the wet area and consists of similar mixing blades 93, each of which two adjacent mixing blades lying in the same axial plane form a pair, the peripheral areas thereof are connected via an axial web 95.
  • a total of four such webs 95 are provided, which are arranged distributed uniformly over the circumference of the mixing element 9 and are offset by one web length in the axial direction.
  • the function of the webs 95 corresponds to that of the web 55 in FIG. 2.
  • the intermediate spaces 94 between the mixing blades 90 to 93 which are large in comparison to FIG in Figure 1.
  • FIG. 4 shows a further development of the device according to FIG. 1.
  • This further developed device is used for the production of pumpable mortar from binder and sand, in particular for the production of liquid screed. Therefore, the screw mixing device 4 is equipped here with the mixing element 9 according to FIG. 3. All other parts of the device, already shown in FIG. 1, are provided with the same reference numerals as there.
  • the device according to FIG. 1 is charged with ready-to-use dry mortar via its filling shaft 3
  • the device according to FIG. 4 is primarily intended for the construction site-based production of a pumpable mortar mass, here liquid screed, from binder and sand.
  • the binder comes from a silo to be presented above the funnel-shaped outlet 1.
  • the sand comes from the construction site and is added via a sand feed hopper 20, the tubular neck 20a of which opens into the jacket of the screw mixing device 4 above an opening 4a.
  • the opening 4a is located downstream of the water connection piece in the conveying direction 11.
  • the funnel 20 is detachably mounted on a box-shaped attachment 21.
  • the sand is fed to the hopper 20 by means of a metering conveyor belt 22 which is known only as a symbol and which discharges sand from a generally funnel-shaped loading shaft 23 in an amount which can be adjusted via an orifice 23a which is adjustable in the direction of the double arrow shown.
  • the metering conveyor belt 22 is supported with its discharge end on a holder 24 which is rotatably arranged (not shown) on the upper edge of the hopper 20 and also carries a gear motor 25 which drives a sand screw conveyor 26 arranged in the funnel neck 20a.
  • This has a web 26a on its inlet side, which extends at a short distance parallel to the inner wall of the sand feed hopper 20 and, since it rotates with the sand conveyor screw 26, acts as a sand scraper.
  • the speed of the geared motor 25 and thus the screw conveyor 26 is selected so that the desired mixing ratio of e.g. 1: 1 from binder to sand. This speed can be 40 to 60 rpm, while the speed of the drive unit 6, 6a, which supplies the binder, can have a value of, for example, between 200 and 400 rpm.
  • the amount of sand supplied to the sand feed hopper 20 via the metering conveyor belt 22 is adjusted so that sufficient sand is constantly present in the latter.
  • the improved device according to FIG. 4 can of course also be loaded with ready-to-use pre-mixed dry mortar.
  • the parts described above for feeding sand are then inoperative.
  • the sand loading hopper 20 can remain in place or can be detached from the attachment 21 and closed by a corresponding cover.
