Definitions

  • Rotary peristaltic pumps for conveying pasty masses are known.
  • the promotion takes place with an essentially two-armed rotor, at the ends of which rollers are rotatably mounted.
  • the rollers run over a hose, which is supported on the side opposite the rollers on the cylindrical inside of the pump housing.
  • the hose ends are connected to the pump inlet and the pump outlet.
  • the hose is filled with the mass to be conveyed.
  • the tube is pressed onto the housing in such a way that the tube sections in front of and behind each roller are separated from one another during a certain operating range and the tube sections thus created contain parts of the mass to be conveyed which are separate from one another.
  • the mass in the hose area between the two rollers is shifted between the inlet and outlet in the hose with the rotor rotating, the mass located between the first roller in the direction of rotation and the outlet is conveyed out of the pump outlet.
  • the mass to be conveyed is introduced into the hose from a storage container.
  • the invention relates to such a pump when it is to be used in particular as a concrete delivery pump in the processing of so-called ready-mixed concrete, and in particular it is concerned with the drive of the rotor and the consequent arrangement of the inlet and the outlet of the pump.
  • a pump according to the invention is shown in the drawing as a central longitudinal section.
  • a hose 2 lies against the cylindrical inner wall of the pump housing 1.
  • the pump housing 1 is evacuated.
  • the inlet end 3 of the hose 2 is connected to a reservoir 4 for ready-mixed concrete to be processed.
  • Its outlet end 5 is connected to a distribution pipe system 6.
  • a rotor 7 rotates in the housing 1, the conveying direction of which is indicated by the arrow 8. 180 offset from one another, 7 rollers 9, 10 are rotatably mounted on the rotor. If the rotor 7 rotates in the direction of the arrow 8, the rollers 9, 10 rotate in the direction of the arrows 11 because they run over the hose 2 with the rotor 7 rotating.
  • the distance between the rollers 9, 10 and the inner wall of the housing is dimensioned such that, in the region of the rollers 9, 10, the tube 2 is placed on the wall of the wall lying on the wall, and so in the operating position shown there are three separate chamber sections: the first section 12 between the front roller 9 in the direction of rotation and the pump outlet 5, the second section 13 between the two rollers 9, 10 and the third section 14 between the rear roller 10 in the direction of rotation and the pump inlet 3.
  • the concrete in the first section 12 is conveyed in the direction of arrow 15 into the pipe system 6 and therein to the processing point, the concrete in the second section 13 is conveyed in the direction of arrow 16 to the outlet 5 pushed and in the third section 14 concrete is sucked out of the reservoir 4 into the hose 2 in the direction of arrow 17 or pushed in with a feed wheel 4a.
  • Inlet and outlet have parallel axes, ie they are offset by 180 °.
  • rollers 18 of the rotor 7 are arranged between the two rollers in both circumferential directions, although only half of them are shown, while from the other half of the rollers 18 only the bearing holes of the rotor 7 are shown, which are arranged in the front of the rotor consisting of two shields, which in the left area of the drawing has broken away (breaking edge 19).
  • a rotor system with a so-called 173 ° housing is known. If the lower pressure roller 9 has squeezed the pump hose 2 tightly and wants to start the conveying process, the upper pressure roller 10 has already released 50% of the compressed pump hose, so that the pump hose, which is now half open, causes a setback due to the concrete column to be conveyed can, which must be caught by the pump tubing 2.
