Definitions

  • the present invention relates to a pump device and one containing this pumping device System according to the independent patent claims.
  • the present invention is therefore the object based on a pumping device or a pumping device to create containing system which is small and reliable at low cost Promotion of pasty products with a high Ensures pump performance.
  • Claim 1 claims a pump device, in particular for suctioning pasty media from storage containers, such as disposable containers or the like, where the pump device a first clutch for pressure-tight Connection to the storage tank as well as a second clutch for coupling a drive device has, the pumping device of the first Coupled downstream of a pump with one with the Includes drive device connectable rotor and this pump is pressure-tightly connected to a pressure chamber which is in turn pressure-tight with a connection for a hose for conveying the pasty Fluid is connected out of the pressure chamber.
  • pressure-tight is one in the present case Understand pressure tightness, which is an unhindered Suction flow of the pasty medium to be conveyed out of the storage container without it here the delivery rate comes to a standstill or for an air entry into the pasty medium.
  • pressure tightness is at least 5 bar.
  • the pump device has the advantage that it can be made very small and thus also with little effort on distant Construction sites can be applied.
  • the pumping device is here with a first clutch to one Storage container, preferably a disposable container can be coupled and on the other hand to a second clutch can be coupled for coupling a drive device.
  • the flow of the pasty medium from the disposable container takes place through the area of the first clutch in a downstream pump, the rotor of the drive device is driven and this Pump pressure-tight with a subsequent pressure chamber is connected, which in turn is pressure-tight with one Connection for a hose to convey the pasty Fluid is connected out of the pressure chamber.
  • the structure of a system according to the invention particularly easy to ensure locally, because the pumping device according to the invention simply between a disposable container to be emptied and a corresponding one Drive device is mounted and thus a system for the provision of pasty products given is.
  • a particularly advantageous further training provides that the flow cross section in the pressure chamber from End of the pump up to the connection to one to be connected Hose is always larger than the flow cross-section at the outlet of the connection.
  • Flow cross-section is the free cross-sectional area understood through which seen from the pump towards connecting actually pasty medium is possible. So this flow cross section is conceivable as a surface that is perpendicular to a imaginary flow thread which is from the center the pump outlet to the center of the connection runs, with the flow cross-sectional areas always perpendicular to this imaginary flow thread lie.
  • the protruding head of the rotor which is used, for example, in a screw pump runs, correspondingly far from the screw pump be led out or bevelled to the screw pump to be as large as possible and to ensure the largest possible flow cross-section, so it's not going to be in this area Constipation is coming. It is particularly important that the flow cross-section is always in this area is larger than the cross-section at the outlet of the connection, for example by 10%, preferably by 20 %, particularly preferably 30% larger in cross-sectional area.
  • a screw pump is provided as the pump which is a stator with an inner rubber jacket having.
  • the rubber jacket to the pressure chamber an outlet slope has, which is in the axial direction of Pump over at least 10 mm, preferably 15 mm, especially preferably extends 20 mm.
  • the angle of this discharge slope opposite the surrounding jacket of the stator an angle ⁇ (see FIG. 3b) of 25-65 °, preferably 50 - 60 °.

  • This screw pump preferably has one Stator with an inner rubber jacket. Through this The pressure builds up on the pump Pressure chamber of up to 60 bar, preferably up to 80 cash possible. Here it is possible that to be funded pasty material through hoses over 60 m long (which for example has an inner diameter of 25 mm) to promote.
  • the first coupling with which the pump or the Pump device connected to a storage container can be implemented in several ways. critical is that this connection is pressure tight and easy coupling is possible. So it is for Example possible, this first coupling as a screw thread, Rotary quick coupling (such as fire hoses), as a lockable plug or to be designed as a simple plug closure.
  • An easy one Buckle with a corresponding counter is a particularly simple variant because the suction pressure exerted by the pump "pulling up" the pumping device to the container becomes.
  • a check valve may be provided which has a discharge when the pump device is removed prevented from pasty medium from the container.
  • the pressure chamber downstream of the pump has a corresponding one Has pressure chamber housing.
  • This can be designed so that the stator of the screw pump insertable into this pressure chamber housing or with this (for example via a double thread) can be clamped is. So in a simple way, for cleaning or maintenance purposes, the pump be separated from the pressure housing.

Offers for storage it is particularly important that the adapter in the pressure chamber housing via a double-sided rubber seal stored with an intermediate fat pad is.
  • the rotor towards the pressure chamber housing i.e. drive side, eccentrically movable. That is, that in the End of the rotor protruding from the pressure chamber housing the contour of the inner rubber jacket of the screw pump moved eccentrically.
  • An adapter ensures this for an eccentric compensation to the purely axial rotating drive element. So it comes here quasi a gimbal compensation. this happens preferably through the adapter itself. However, it is also possible that on this adapter left and connecting parts on the right in the axial direction are given, which are then a "bridging" on the one hand towards the rotor and on the other hand to the drive element, for example an external one Drill, form.
  • the adapter in the axial direction of the pump device between the pump and the center of the connection i.e. offset relatively far from the pump. This will causes by the eccentric compensatory movement the adapter a "push in” of pasty Medium to the connection and thus to the hose there happens. It is particularly important for the present Invention that the adapter is relatively far Pump is oriented towards and not in the rear Dead space of the pressure chamber housing is stored. As In the present case, the "middle" of the connection becomes the middle Point of the transition area from the pressure chamber housing seen towards the connection, which on the Projected central axis of the pressure chamber housing is that the projection line is perpendicular to the axial Center line of the pressure chamber housing.
  • the mounting points of the adapter are always assumed, these are preferably axes of rotation, which thus housed in the area of the pressure chamber housing should be which between the pump outlet on the one hand and the middle of the solder described above of the connection.
  • the adapter has an "H” shape, this means on the one hand easy assembly and good storage possible, in addition, the "paddle-shaped" shape causes one particularly good funding or a particularly good one Pushing in the pasty medium to the connection out.
  • Coupling the adapter is also advantageous or a connecting part connected to the adapter to the rotor head of the protruding from the pump Rotors. It is recommended here in particular that a "T" shaped groove is given is. While in systems according to the prior art only one groove common in a circumferential direction is, according to the invention, a groove is also in the opposite Direction (so that the shape of a "T" results) provided. This makes it possible for the adapter or the connecting part connected to it towards the rotor head in two directions can be controlled by an angular offset and each in engages the end stops positively. in this connection it is possible at the high pressures according to the invention for example by an opposite rotation to achieve that "pressure removed from the system" becomes.
