Definitions

  • the present invention relates to a pumping device as well as to a pumping device containing system according to the independent claims.
  • Pumping devices for removing pasty media from storage containers are known in principle. For example, it is common to place a pasty material in a device for continuously conveying a pumpable material. In this case, the material is mixed regularly in a first chamber of this device and a downstream pump, the material pressed through a mortar tube.
  • a disadvantage of these complex devices according to the prior art is that in these expensive devices and the associated relatively long transport routes even the smallest leaks in the system leads to a loss of pump power and thus the material delivery is impossible.
  • First of all, in these complex devices there is a high outlay for troubleshooting, which results in the high number of individual components involved and a high cleaning effort after the end of the conveyance. This means on the one hand a high cost burden by these known devices and on the other hand a cumbersomeness, which makes it difficult to transport in particular to distant construction sites.
  • DE 195 42 527 A1 shows a conveyor device for conveying viscous flowing medium with a feed pump with all the technical features of the preamble of claim 1, which has a helical rotor inserted in a housing.
  • the rotor is connected via a cardan shaft with an associated gear.
  • a delivery pump is provided with a helical rotor which is movable in an inner rubber jacket. Subsequently, a pressure chamber for further conveying pasty medium is connected to this pump.
  • the present invention has for its object to provide a pumping device or a pumping device containing this system, which is physically small and ensures low cost reliable delivery of pasty products at a high pumping capacity.
  • Claim 1 claims a pumping device, in particular for sucking pasty media from storage containers such as disposable containers or the like, wherein the pumping device comprises a coupling for coupling a drive device, wherein the pumping device comprises a pump with a rotor connectable to the drive device and this pump is pressure-tightly connected to a pressure chamber, which in turn pressure-tight with a connection for a hose for conveying the pasty medium from the pressure chamber out, wherein the pump is a screw pump, which has a stator with an inner rubber jacket, wherein the rubber jacket to the pressure chamber toward enlarging the annulus for pasty medium has a discharge slope, which extends in the axial direction over at least 10 mm and the pumping device has a coupling for pressure-tight connection to the storage container and the pump is arranged downstream of the coupling for the pressure-tight connection to the storage container.
  • the pumping device comprises a coupling for coupling a drive device
  • the pumping device comprises a pump with a
  • pressure-tight in the present case is to be understood to mean a pressure-tightness which allows an unimpeded suction flow of the pasty medium to be conveyed out of the storage container, without the delivery being stopped or an air being introduced into the pasty medium.
  • the pressure tightness is at least 5 bar.
  • the pumping device has the advantage that it can be designed very compact and thus can be applied to distant construction sites with little effort.
  • the pump device can be coupled with a first coupling to a storage container, preferably a disposable container, and, on the other hand, can be coupled to a second coupling for coupling a drive device.
  • the flow of the pasty medium from the disposable container takes place through the region of the first clutch in a downstream pump whose rotor is driven by the drive device and wherein this pump is pressure-tight connected to a subsequent pressure chamber, which in turn connected pressure-tight with a connection for a hose for conveying the pasty fluid from the pressure chamber out is.
  • the structure of the system is particularly easy to ensure decentralized, since the pumping device is easily mounted between a disposable container to be emptied and a corresponding drive device and thus a system for providing pasty products is given.
  • flow cross-section in the pressure chamber from the end of the pump to the connection to a hose to be connected is always greater than the flow cross-section at the outlet of the terminal.
  • flow cross-section is understood to mean the free cross-sectional area through which, as seen from the pump, connection to actually paste-like medium is possible.
  • This flow cross-section is therefore conceivable as a surface which is perpendicular to an imaginary flow thread, which extends from the center of the pump outlet to the center of the terminal, the flow cross-sectional areas are always perpendicular to this imaginary flow thread.
  • the flow cross-section in the pressure chamber from the end of the pump to the connection in particular in the area before the connection significantly larger, for example, more than 10% larger than in the outflow cross-section of the terminal 9. It will, as in the entire present application, assumed that the diameter of the output cross-section of the terminal is at least equal to the diameter of the connected hoses or even larger.
  • the protruding head of the rotor which runs, for example, in a screw pump, be led out far enough from the screw pump or be beveled to the screw pump to ensure the largest possible annulus and the largest possible flow cross-section, so that it in this area does not come to blockages. It is particularly important that in this area always the flow cross-section is greater than the cross-section at the outlet of the terminal, for example by 10%, preferably by 20%, more preferably by 30% larger in cross-sectional area.
  • a screw pump which has a stator with an inner rubber jacket.
  • the rubber jacket to the pressure chamber towards a discharge slope which extends in the axial direction of the pump over at least 10 mm, preferably 15 mm, particularly preferably 20 mm. It is particularly advantageous in this case that the angle of this outlet bevel relative to the surrounding jacket of the stator forms an angle ⁇ (see FIG. Fig. 3b ) of 25-65 °, preferably 50-60 °.
  • the screw pump has a stator with an inner rubber jacket.
  • the first clutch with which the pump or the Pumping device is connected to a storage container can be carried out in several ways. It is crucial that this connection is pressure tight and easy coupling is possible. It is thus possible, for example, to design this first coupling as a screw thread, rotary quick-action coupling (such as in fire hose), as a lockable plug-in closure or as a simple plug-in closure.
  • a simple plug-in closure with a corresponding counter-lock is a particularly simple variant, since the suction pressure applied by the pump ensures that the pumping device is attracted to the container.
  • a non-return flap can be provided, which prevents a discharge of pasty medium from the container when the pump device is removed.
  • the pressure chamber arranged downstream of the pump has a corresponding pressure chamber housing.
  • This can be designed so that the stator of the screw pump in this pressure chamber housing can be inserted or with this (for example via a double thread) can be clamped.
  • the pump can be separated from the pressure housing.
  • the pressure chamber has a pressure chamber housing and that the stator of the pump (screw pump) in the pressure chamber housing can be inserted or clamped with this.
  • the stator of the pump screw pump
  • here offers a bracing means of, for example, two axially along the pump running tie rods. This makes it possible, on the one hand, a strong coupling and pressure tightness To achieve these elements, on the other hand, an easy interchangeability of the pump or easy cleaning is possible.
  • a particularly advantageous development provides that the rotor of the pump is connected via an adapter to the drive element of the drive device.
  • this adapter has driver connections on both sides, which on the one hand ensure the connection to a drive element of the drive device and on the other hand, the rotor drive of the pump is realized.
  • this adapter structure it is possible with this adapter structure to avoid a pressure loss in the region of the drive element of the drive device.
  • the adapter can be stored and sealed, for example, in the pressure chamber housing, even when uncoupling the drive element, this does not lead to a pressure drop in the pressure chamber.
  • the adapter is mounted in the pressure chamber housing via a double-sided rubber seal with an intermediate fat pad.
  • rotor to the pressure chamber housing out, ie drive side, eccentrically movable. That is, the end of the rotor protruding into the pressure chamber housing moves eccentrically due to the contour of the inner rubber sheath of the screw pump.
  • An adapter provides eccentric compensation for the purely axially rotating drive element. It comes here so to speak to a gimbal balance. This is preferably done by the adapter itself. However, it is also possible that on this adapter left and right in the axial direction then subsequently connecting parts are given, which then form a "bridging" on the one hand to the rotor and on the other hand to the drive element, for example, an external drill down.
  • the adapter is in the axial direction of the pumping device between the pump and the center of the terminal, i. offset relatively far to the pump. This causes the eccentric compensating movement of the adapter to result in a "push-in” of pasty medium towards the connection and thus towards the hose. It is particularly important for the present invention that the adapter is oriented relatively far to the pump and is not stored in the rear dead space of the pressure chamber housing. As the "center" of the terminal, in the present case, the middle point of the transition area from the pressure chamber housing to the terminal is seen, which is projected onto the central axis of the pressure chamber housing so that the projection line is perpendicular to the axial center line of the pressure chamber housing.
  • the bearing points of the adapter are preferably axes of rotation, which should therefore be accommodated in the region of the pressure chamber housing, which lie between the pump outlet on the one hand and the center of the above-described solder of the terminal.
  • the rear, i. directed away from the pump axis of the adapter is up to a diameter of the end cross-section of the port further away from the pump.
  • the adapter has an "H” shape, as a result of which, on the one hand, easy mountability and good storage are possible,
  • the "paddle-shaped" shape causes a particularly good promotion or a particularly good pushing of the pasty medium to the connection.
  • a coupling of the adapter or a subsequent to the adapter connection part to the rotor head of the protruding from the pump rotor is particularly recommended.
  • a "T" -shaped groove is specified. This makes it possible that the adapter or the adjoining thereto connecting part to the rotor head can be controlled in two directions with an angular offset and engages positively in each case in the end stops. In this case, it is possible to achieve at the high pressures, for example by an opposite rotation, that "pressure is taken out of the system".
  • the second clutch is a rotary quick-release coupling (this is particularly useful in the coupling of mobile electrical drives, such as drills, etc.) or a shell clutch (this is useful especially for larger engines).
  • the electric drive device may be, for example, a continuously variable drive or a hand drill, which has a power consumption of only 1.8 kW. This is advantageously connected via a floor stand with the ground, so that it does not have to be held by hand, but automatically is fixed and thus a fixed distance to the container is given.
  • the system according to the invention is particularly suitable for containing disposable containers filled with pasty media, such as ready-mixed mortar or paint.
  • the corresponding disposable container the characteristics of the disposable container after the DE 202 13 063 U1 , filed on August 21, 2002, assigned to the same assignee.
  • the pumping device according to the invention it is possible to transport ready-mixed mortar from the disposable container over distances of up to 60 m, preferably up to 100 m, by means of a hose to be connected to the pumping device.
  • the pump device is characterized in particular by an easy cleanability. For this purpose, after uncoupling the pumping device on the first clutch, the pump is plugged, for example, into a bucket of water and the drive device is switched on, so that self-cleaning is achieved by flushing through the pumping device.
  • Fig. 1 shows an inventive system 14 for providing pasty products, especially on construction sites.
  • This shows a pumping device 1 which is connected to a storage container 2 in the form of a disposable container.
  • the connection is made via a first, pressure-tight coupling 3, which is designed here as an external thread, which is screwed into the container 2.
