Definitions

  • the invention relates to a device for conveying flowable materials, in particular mixtures composed of a liquid or liquids and a solid or solids, by means of a flexible, tubular line provided with an inlet connection and an outlet connection, which with its outer line wall forming the outer circumference of the line a cylindrical bearing surface is supported and, with its inner line wall forming the inner circumference of the line, forms the running surface for at least one press roller rotating from the inlet connection piece to the outlet connection piece.
  • the conveyance of flowable materials, in particular aggressive substances, by means of a displacement pump called a peristaltic pump is generally known.
  • the peristaltic pump usually has a small delivery rate and is used primarily in smaller systems, for example in pilot and experimental systems.
  • a hose made of elastic material is passed around the inner circumference of a cylindrical housing revolving rollers pressed together in such a way that the hose volume between two rollers is separated from the suction side and conveyed to the pressure side. Since, apart from the hose, no other parts come into contact with the conveyed material, such pumps can advantageously be used to convey aggressive media, although there are limits to the hose material, which must be flexible but wear-resistant.
  • Another disadvantage is that the continuous squeezing of the hose requires relatively large outputs, which is why the efficiency of such a hose pump is low. For this reason, peristaltic pumps with high performance cannot be economically manufactured.
  • the device shown in FIGS. 1 and 2 is used to convey flowable materials, which means any number of flowable mixtures, but there is also the possibility of conveying liquids with this device that have no solid content.
  • the device has a cylindrical bearing surface 1, which extends over a circumference of 270 0 and has one leg 2, 3 at each end.
  • the legs 2, 3 collide at right angles and are connected to one another at their joint 4, for example by welding.
  • the bearing surface 1 forms, together with the legs 2, 3, an annular frame which, see FIG. 2, is supported on a support groove 6 by two arms 5.
  • the support groove 6 has a hub 7 on its axis 8 coincides with the axis of the cylindrical bearing surface.
  • a flexible, tubular line 9 which also extends along the legs 2, 3 and which is provided at its ends with an inlet connection 10 and an outlet connection 11. If the device runs in the opposite direction to that indicated by the arrow in FIG. 1, the connector 10 becomes the outlet connector and Port 11 inlet port.
  • rollers 12 which are rotatably mounted on a rotating disc 13. According to FIG. 1, four rollers 12 are provided, but a different number of rollers can also be selected. A conveying effect would already be achieved with a roller 12, but the arrangement of at least two rollers 12 is recommended in order to increase the conveying effect on the one hand and to achieve a force balance on the support column 6 on the other.
  • the rollers 12 can be fixed on the support disk 13 at a fixed distance from the axis of rotation 8. In view of the conveyance of very different materials, however, it is expedient to be able to fasten the press rollers 12 at an adjustable distance, which can be achieved in a simple manner, for example by an eccentric. It is also possible to provide the rollers 12 with a safeguard, which can deflect against the center when a certain pressing force is exceeded.
  • the cylindrical bearing surface 1 is open on both sides. So that the tubular line 9 is aligned with the rollers 12, it is attached to the cylindrical bearing surface 1.
  • the fastening is carried out by means of bolts 14 which are inserted through a bore 15 in the tubular line and a bore 16 in the cylindrical bearing surface 1 and are fastened with a nut which is supported on a disk 18.
  • the bolt 14 has a flat head 19, so that the compression of the tubular line according to the dash-dotted position in FIG. 3 can proceed without hindrance when a disc 12 rolls over this point.
  • the number of bolts 14 is adjusted according to the size of the device.
  • the bolt 14 can be embedded and vulcanized into the material of the line 9 with its head 19.
  • the number of fastening points can also be chosen arbitrarily.
  • a continuous fastening of the outer pipe wall 20 to the inner wall of the bearing surface 1 is also conceivable, but adequate guiding of the pipe 9 is also achieved by a discontinuous fastening by means of bolts 14.
  • the distance of the roller 12 on the support disk 13 is adjusted such that the tubular line 9 is compressed to a greater or lesser extent.
  • the device maintains its conveying effect, in particular in that in the case of viscous materials there is a coherent material flow which flows in or flows in on the suction side.
  • the support disk 13 is used for the rollers 12 as a driven wheel of a toothed or an enveloping drive.
  • a corresponding profiling is arranged on the circumference of the disk 13, e.g. a gearing.
  • the drive of the support disk 13 is carried out by an enveloping drive 22, e.g. by a chain drive, the pinion 23 on the shaft of a motor 24, e.g. an electric motor is arranged.
  • the motor 24 is attached to a bracket 25, which in turn is attached to the leg 2 of the frame.
  • the driven wheel 13, which is also a supporting disc, is mounted in the hub 7 by means of a shaft 26.
  • the inlet-side and outlet-side parts of the line 9 are guided close to one another in the region of the joint 4, so that the inlet connection 10 lies directly on the line part leading to the outlet connection 11. It would also be possible to choose a cylindrical bearing surface larger than 270 °, e.g. between 300 and 360 °. In this case, the corresponding parts of the line 9 have to be routed side by side so that they can be pressed by the rollers 12 without mutual interference.
  • the simple structure of the device described makes it possible to convey materials of the most varied types without difficulty under difficult conditions. Since the frame 1, 2, 3 is open on both sides, the support disk 13 can also be driven by arranging blades between the rollers 12 and the entire device by simply immersing it in a flowing one Water is driven. The maintenance effort is also small. It is possible that, due to the material being conveyed, the tubular line 9 has to be replaced over time. As can be seen from FIG. 1, it is then sufficient to loosen the nuts 17 of the connections of the line 9 to the frame 1, 2, 3 and connecting means, for example hose clips 27, on the connecting pieces 10, 11, to remove the line 9 and install a new line 9 and fasten it in the same way to the frame 1, 2, 3 and to the connecting piece 10, 11.
  • the relatively low power requirement of the device described allows such devices to be produced with a large conveying capacity, frame diameters of 1-2 m and line diameters of up to 200 mm being possible.
  • the device described can also be used as a juicer.
  • the tubular line 9 is to be provided with screen openings or to be made from screen material.
  • the device can then expediently be horizontal, i.e. with a vertical axis of rotation 8.
