Definitions

  • the invention relates to a conveying device according to the preamble of claim 1.
  • the publication CH 580 229 discloses a conveying device for regulating the delivery rate of centrifugal pumps. This in itself very proven, reliable and inexpensive conveyor device has the disadvantage that it is more expensive to maintain and that it is limited in terms of arrangement options.
  • the object of the invention is to propose a more advantageous conveyor device.
  • a conveying device with automatic regulation of the delivery quantity comprising a pumping device, a suction container and a suction sump, the suction container having a suction space which is connected to the suction sump via an overflow edge and via a supply channel opening tangentially into the suction container, and wherein the pumping device comprises a suction tube and a fluidically connected to the suction tube centrifugal pump, and wherein the suction tube protrudes from above into the suction container, and wherein the Zuleitkanal aligned according to the direction of rotation of the centrifugal pump opens into the suction container, and wherein the suction tube via a connecting pipe is connected to the centrifugal pump, and wherein the connecting tube has a portion which extends with respect to the suction pipe at an angle ⁇ between 45 ° and 135 °.
  • the conveying device comprises a suction space which is designed as a container, in particular as a cylindrical or prismatic container, the upper edge of the container forming an overflow edge towards the suction sump.
  • the container is fluidly connected via a tangential supply fluid to the suction sump, wherein the supply line preferably extends from the bottom of the container to the overflow edge, and the supply line thus forms an open-topped channel between the suction sump and the container.
  • the liquid supply takes place exclusively through the Zuleitkanal, thanks to the tangential mouth with swirl generation, the twist is generated depending on the liquid level in the suction sump.
  • the supply channel is arranged such that the swirl generated in the container has the same direction of rotation as the centrifugal pump.
  • the conveyor device therefore has an automatic regulation in that the pump can preferably be operated at a constant speed, wherein the delivered amount of fluid automatically adapts depending on the liquid level in the suction sump. It has surprisingly been found that a reliable conveying of the liquid between the suction pipe and the centrifugal pump, especially at low flow rates, is still possible even if a connecting pipe is arranged between the suction pipe and the centrifugal pump.
  • the connecting tube may also have a portion which extends at an angle ⁇ between 45 ° and 135 ° with respect to the suction tube, in particular at an angle ⁇ of 90 ° or substantially 90 °.
  • the connecting tube has a partial section which extends horizontally or substantially horizontally.
  • the suction container and the centrifugal pump are arranged in two spaces separated by a wall, wherein the Connecting pipe passes through the wall.
  • This arrangement has the advantage that the space in which the suction sump and the suction tank are located is separated by a wall from the space in which the centrifugal pump is located.
  • the centrifugal pump can be placed in a separate and preferably dry room, so that the centrifugal pump is preferably easily accessible for maintenance.
  • the wall allows for more benefits.
  • the space in which the centrifugal pump is located be protected from odor emissions or pollutants.

  • the centrifugal pump can be easily mounted and optionally also dismantled.
  • the centrifugal pump is better protected against moisture and against aggressive substances. This allows in particular a more reliable operation and easier maintenance of the centrifugal pump or the entire conveyor.
  • the inventive conveyor device also has the advantage that the centrifugal pump can be arranged at a certain distance with respect to the suction tube, so that more degrees of freedom with respect to the arrangement of centrifugal pump and suction tube are possible, whereby more optimal arrangements of Centrifugal pump and suction tube are possible.
  • the inventive conveyor device also has the advantage that the suction sump and the suction can be arranged in an accessible but closed space, and that the centrifugal pump can be arranged in a separate, dry room.
  • the closed space, in which the suction sump and the suction tank are located in particular prevents odor emission to the outside, whereas the centrifugal pump is easily accessible, and the separate, dry space in which the centrifugal pump is located is preferably odorless.
  • the conveying device according to the invention thus has a low odor emission towards the outside, and preferably has a separate space for the centrifugal pump, which is preferably dry and preferably odorless.
  • the conveyor device also has the advantage that the centrifugal pump can be actuated with an on-off device. This means that it is sufficient to turn on and off the centrifugal pump to operate the entire conveyor, or in other words, there is no device for controlling the speed of the centrifugal pump required to operate the conveyor.
  • This provides the advantage that the drive device can be made very cost effective and very reliable.
  • a control or regulating device is used to control the centrifugal pump, which is at least one setpoint specified, wherein at least one actual value or a process value of the conveyor is measured, for example, the height of the liquid level in the intake or the flow rate.
  • the control or regulating device controls the centrifugal pump in a preferred Embodiment such that it is only switched on and off.

In a further possible arrangement could also be dispensed with the partition 6.
  • the partition wall 6 could also be formed from a plurality of juxtaposed partial walls, wherein the partial walls could also be mutually spaced, wherein the intermediate space designed as a cavity could be or could be filled with a means such as an insulating agent.

  • the suction tube 2c has in particular a suction height L3 between 0.5 meters and 8 meters.
  • FIG. 1 also shows possible levels of the fluid.
  • the fluid may have a maximum level 5c in the suction sump 4, the fluid usually having a lower level, for example the level 5a, so that the fluid flows via the supply channel 3b into the suction space 3h, so that, for example, the liquid surfaces 5b, 5d in the suction space 3h and 5e train.
  • FIG. 3 shows a further embodiment of a conveyor device 1.

  • the fact that the centrifugal pump 2a and the suction pipe 2c can be arranged at different locations results in particularly advantageous arrangement possibilities.
  • the swirl is maintained by the fact that on the one hand in the inlet region of the suction pipe 2c, that is, in the suction 2h a swirl S 1 is generated, and that on the other hand by the centrifugal pump 2a, a swirl S2 is generated, the forth of the centrifugal pump 2a on the in Connecting tube 2e located liquid acts.
