Definitions

  • the present invention relates to a pumping and mixing device for powdered or free-flowing media and a system for providing pasty media for construction purposes.
  • the conveyor shaft is adapted to be inserted or introduced into the storage container, thus promoting powdered or free-flowing medium as continuously as possible from this closed container out. This then optionally passes into a flow chamber, whereby a certain homogenization of the delivery process can be achieved.
  • the repellent from the pumping and mixing device according to the invention free end of the conveyor shaft is preferably carried out cantilevered into the storage container.
  • a common drive for the mixing and conveying shaft mounted at the opposite end of the mixing chamber effects the drive. This is advantageous over "on both sides suspended" conveyor shafts, which are difficult to fix in the storage container (especially if it is a disposable container) or where the conveyor shaft must necessarily be part of the container.
  • a projecting end of the conveyor shaft Taken individually, they are inserted into a storage container such as a disposable container or the like, the corresponding drive being made from the "back" of the device.
  • the housing of the pumping and mixing device has a flow chamber, wherein this flow chamber downstream of the metering chamber is arranged and the metering chamber is compared to the flow chamber at least partially reduced in cross-section.
  • this flow chamber is not absolutely necessary, especially if other characteristics are given for it.
  • a separate flow chamber is not necessary. This is because a corresponding cross-sectional widening is already given in the storage container itself. It is then spoken of a "flow area", which replaces the flow chamber. From the flow area, which is housed in the storage container, there is naturally a cross-sectional reduction to the interior of the dosing out.
  • the metering chamber at the end facing away from the mixing chamber projects beyond the flange of the pumping and mixing device to the storage container. In other words, it projects beyond, for example, the screw thread or the quick-action closure, so that it is ensured that the foremost end of the metering chamber likewise extends or projects into the storage container itself, so as to achieve a flow area according to the invention.
  • a metering chamber Downstream of the flow area or the flow chamber is then a metering chamber, which at least partially reduced cross-section is compared to the flow chamber or the flow area. It has been shown that a further equalization of the promotion is achieved by this intermediate chamber.
  • a mixing chamber Downstream of the metering chamber is then given a mixing chamber, which is open cross-sectionally reduced towards the metering chamber.
  • the conveyor shaft which extends into or through the metering chamber, is connected to transmit power to a mixing shaft.
  • This mixing shaft ensures in the mixing chamber that from a water connection, which opens into the mixing chamber, water is provided for mixing the powdered or free-flowing medium with water to a pasty mass.
  • a connection for conveying the pasty mass is finally given, so that the mass pressure can be further promoted to higher floors of a building and thus can be brought directly to the processor out.
  • This pumping and mixing device is particularly interesting in connection with a disposable container for providing powdered and free-flowing media, as disclosed for example in DE 20 2004 010 486 of the same applicant.
  • a disposable container for providing powdered and free-flowing media, as disclosed for example in DE 20 2004 010 486 of the same applicant.
  • Such a container is preferably constructed of materials such as corrugated cardboard and thus has a very low weight.
  • the container is in this case designed in particular for receiving the conveyor shaft, so that here results in a continuous flow of powder and a good emptying.
  • further disposable containers originating from the applicant For example, according to DE 103 14 146 A1, DE 202 13 063 U1 or EP 03 09 0261 A1 are used. All features of these applications are (to avoid repetition) here by reference in the present application as recorded, in particular the features relating to the connection of devices to the outlet opening of the disposable container.
  • the pumping and mixing device provides that the front part of the housing is substantially pressure-tight to the storage container / the disposable container by means of a screw thread, a quick release or the like can be connected. This results in a standardized connection point, the provision of powdered material is continuously given by this secure connection.
  • the conveyor shaft is designed as a screw conveyor.
  • the conveyor shaft can also be designed as a spiral.
  • This spiral shape is extremely advantageous for loosening up the powdery and free-flowing material in the container. Since the spiral engages relatively far down in the storage container / disposable container, the pressure by the material itself is very high, it usually comes to compression due to self-weight compaction. Here is ensured by the spiral, that it comes here to a loosening, by the given in the one-way container slope (s., Applicant's applications referred to in the introduction), it comes to a assisted by the spiral lead out of the powdery material from the disposable container.
  • This spiral can be made in various ways.
  • additional baffles for powdery material may be present, which may also cause (not necessarily desired) stiffening of the spiral.
  • Also advantageous is a decreasing spiral distance of the spiral in the direction of the storage container, which also reduces the risk of blockages.
  • the free end of the conveyor shaft (preferably when this is designed as a spiral) is cantilevered in the storage container. This results in a "self-centering" of the screw, even if this has a certain bending elasticity, a very good function is given.
  • a further advantageous embodiment provides that the flow chamber has a control and metering window. This makes it possible to check the powder flow at any time during operation.
  • a further advantageous embodiment provides that the region-wise reduction in cross-section of the metering chamber is designed as a partition wall separating the flow chamber, in whose center the conveyor shaft is freely rotatable.
  • the conveyor shaft thus passes through the inlet chamber and the adjoining metering chamber, the intervening (belonging to the metering chamber) bulkhead in this case causes a homogenization the promotion, in the central region of the dosing a passage is provided in which the conveyor shaft / spiral is freely rotatable.
  • the ratio of the narrowest cross-sectional area in the metering chamber (that is, for example, the narrowest cross section of the abovementioned bulkhead) of the largest cross-sectional area in the flow chamber is between 0.01 and 0.5.
  • a further advantageous embodiment provides that in the region of the end of the metering chamber, a gap for the passage of medium from the metering chamber is provided in the mixing chamber.
  • a gap for the passage of medium from the metering chamber is provided in the mixing chamber. This can be carried out in various ways, it is crucial that here an attachment of the conveyor shaft is made possible to the subsequent mixing shaft and at the same time a continuous flow of powder through this gap space.
  • the gap is designed, for example, as a drum with axial recesses, which is supported on a side facing away from the flow chamber of the metering chamber and preferably protrudes into the mixing chamber.
  • the ratio of length of the flow chamber to the length of the metering chamber is between 1 and 2.
  • the ratio of the length of the flow chamber to the length of the mixing chamber is preferably between 0.3 and 0.7.
  • a further advantageous development provides that in the end region of the conveyor shaft, which is repelled by the supply chamber, there is a driver connection to the mixing shaft.
  • a driver connection is also possible within the conveyor shaft, in particular in the region of the flow chamber.
  • a mixing shaft is preferably provided centrally, which has radial arms. These can be designed as a radially outwardly aspirant to the mixture of medium (ie powder and water) or as a spiral boom for conveying medium from the storage container on the one hand. Due to the corresponding adaptation of mixing and delivery jibs, a tuning according to the desired conditions (granulation of the powder, of which pasty medium, etc.) is possible. A corresponding adjustment by replacing the mixing shaft is also possible.
  • a particularly advantageous embodiment provides that at the end of the mixing chamber, on the side facing away from the flow chamber of the device, a common drive for mixing and conveying shaft is mounted.
  • a common drive for mixing and conveying shaft is mounted at the end of the mixing chamber, on the side facing away from the flow chamber of the device.
  • the arrangement of the drive on the conveyor shaft repellent side also offers the advantage that a self-centering of the conveyor shaft (especially if this is designed as a spiral) is easily possible.
  • Another advantage is that at this point a drive is easy to install, this case no fixed mounted drive must be provided, it can also be common on the construction existing drives (even drills) can be connected.
  • a further advantageous development provides that a pumping device, for example according to EP 1 445 490 A1 of the same Applicant, is possible at the outlet for connecting a conveying device for conveying pasty masses. This makes it possible that the freshly mixed pasty medium over 30 m, for example, can reach the worker.
  • the modular design also offers the advantage here that the pumping device can alternatively also be connected directly to the disposable container, which already contains pre-mixed pasty medium.
  • the pumping and mixing device has a housing which is divisible into at least two longitudinal sections. This makes it possible, for example, a "metering unit” (consisting of a housing part, which contains the metering chamber and flow chamber) and a “mixing unit” (which contains the mixing chamber) to separate. These longitudinal sections can also be quickly connected to each other again, for example by a clamping device in the form of a quick-release device or a bolt-tensioned clamping device.
  • the inventive system for providing pasty media for construction purposes comprising a pumping and mixing device according to the invention and a correspondingly matched disposable container or a storage container, which or has a connection for introducing the conveyor shaft, also has advantageous developments.
  • the container shape of the pumping and mixing device according to the invention in particular in the region of the conveying shaft or the connecting flange of the pumping and mixing device, follows the disposable container or the storage container. It is particularly advantageous here that the disposable container has a collecting channel in alignment with the conveying shaft.
  • This collecting channel may be made of an extra plastic material, for example, be designed as a plastic injection molded part, or even consist of plain cardboard or optionally be plastic coated or be provided with an applied inliner.
  • the shape of the channel can be conical or flat, both are possible in coordination with the conveyor shaft according to the invention. It is only important that within the container a slope (pyramidal in polygonal cross-sections, essentially conical in circular cross-sections of the container) is given. It is particularly advantageous that the corresponding channel extends to full width or full diameter of the container.
  • the width of the gutter has to be relatively small.
  • the ratio of the largest width of the channel to the largest diameter of the conveyor shaft (within the one-way container) is normally between 0.8 and 2.5, preferably between 0.9 and 1.5.

  • the container has an inner funnel, which opens into a channel, which occupies substantially the full width of the disposable container. At the end of this channel the connection 16 is given. That in the container stored powdery medium is pressed by the weight itself in the direction of the gutter, which can certainly lead to compaction in the gutter.
  • the channel itself may have different cross-sectional shapes, for example, the substantially semicircular cross-sectional shape 20a or the flat or planar cross-sectional shape 20b.
  • a pioneer of the disposable container is that it can be made of a disposable material such as cardboard and therefore is correspondingly lightweight.
  • the construction of the disposable container is possible in various ways, for example by prefabricated plastic parts or by support structures, which may be made of coated cardboard or (if necessary) may be coated with an inliner.

  • Both channels can be mounted in a corresponding disposable container. It is only important here that the disposable container drops to the collection trough, which is executed linear.
  • the channel may extend over the entire width or the entire diameter of the disposable container.
  • the outer shape of the disposable container may be polygonal or round.
  • FIGS. FIGS. 7a to 10 show a further embodiment of the pumping and mixing device according to the invention. All of the above information also applies to this pumping and mixing device, unless otherwise stated below.
  • the pumping and mixing device shown in FIG. 7a (there without drive) is one for powdered or free-flowing media, in particular for connection to a storage container such as a disposable container 2, comprising: a conveyor shaft 3 for insertion into the container Storage container, wherein the repellent of the pumping and mixing device end 3a of the conveyor shaft is cantilevered into the storage container, a surrounding at least a portion of the conveyor shaft housing 4, which has a metering chamber 6 and encloses the metering chamber downstream of a mixing chamber 7, which with a the conveying shaft 3 accommodates force-transmitting connected mixing shaft 8 and a water connection 9 for mixing the medium with water to form a pasty mass, and a at the end of the mixing chamber 7 on the side facing away from the supply chamber 6 side of the device mounted common drive for the mixing and conveying shaft (shown in Fig. 9), and finally an outlet 11 for connection of a conveying device for conveying the pasty mass or for filling into buckets or the like.
  • FIG. 7b shows how the metering chamber 6 with its front end projects beyond the housing 4 or the quick-action closure / screw-type closure over the pumping and mixing device or protrudes out of it.
  • the conveyor shaft 3 projects into the storage container or the disposable container 2, but also the front end of the metering chamber 6. This results in a corresponding cross-sectional reduction already within the container, so that then no additional flow chamber within the housing necessary becomes.
  • Fig. 7c shows a (more to scale) drawing of the article of Fig. 7b.
  • Fig. 7d for this purpose a corresponding lateral section.
  • the Fign. 7a and 7b to remove the mixing shaft 8, which at its end pointing to the dosing chamber has a spiral mixer and otherwise attached to struts 8a "hammer-shaped" cross struts for better mixing.
  • FIG. 8 shows the pumping and mixing device according to FIG. 7a with a stand foot 18, which is provided for adjusting the inclination or height in the rear area with a Steckarretmaschine.
  • Fig. 9 shows the corresponding arrangement, but this time with a flanged drive 21, which has been attached via the flange 22 to the pumping and mixing device.
  • Fig. 10 again shows the complete pumping and mixing device with coupled drive and stand base in a plan view. This is also good to see the clamping device 19 on the housing exterior.
  • the pumping and mixing device according to the invention is characterized in particular by the fact that it can be expanded to a system according to the invention in interaction with a corresponding disposable container.
  • the corresponding disposable container contains here in alignment with the conveyor shaft 3, a collecting channel 20a and 20b, which has a curved, see Fig. 6a or planar, see Fig. 6b, bottom.
  • the ratio of the largest width of the channel b (see Figures 6a and 6b) to the largest diameter (d) of the conveyor shaft within the disposable container between 0.8 and 2.5, preferably between 0.9 and 1, 5 (see in particular Fig. 7b).
