Definitions

  • the invention relates to a tank system for storing a fluid that can be drained by pumps or gravity according to the preamble of claim 1 and to the use of a vortex breaker according to the preamble of claim 8.
  • a fluid stored in a tank In order to remove a fluid stored in a tank, it is drained or pumped out through a tank opening provided for this purpose.
  • the flow towards the tank opening is generated either by simply using gravity or with the help of a suitable pump.
  • flow effects can occur that can lead to the formation of a vortex or whirlpool in the area of the tank opening.
  • Vortex breakers Devices already exist to counteract the formation of such vortices. These devices are also referred to as vortex breakers. However, the vortex breakers that already exist have several disadvantages.
  • the tanks are often under high pressure and must therefore be subjected to a special pressure test before they are used to ensure that they are sufficiently pressure-resistant. If a tank is modified by attaching a whirlpool breaker to prevent the formation of a vortex, this may - depending on the type of installation - require another pressure test. This is particularly true if the structure of the tank is changed (for example by welding) to attach the whirlpool breaker.
  • whirlpool breakers that can be attached to the tank in such a way that a new pressure test is not necessary.
  • the device is typically not attached to the tank itself, but to a section of pipe adjacent to the tank opening.
  • a swirl breaker that extends into the interior of the tank can, under certain circumstances, impair the even mixing.
  • a swirl breaker that extends into the interior of the tank can, under certain circumstances, disrupt the filling process of the tank by obstructing the flow into the tank.
  • the tank system for storing a fluid that can be removed by pumps or gravity.
  • the tank system consists of a tank with at least one tank outlet and a fluid discharge pipe connected to it.
  • the tank system includes a vortex breaker that counteracts the formation of vortices in the area of the tank outlet when fluid is removed from the tank, which usually extends from the outlet into the tank.
  • the tank system is characterized by the fact that the vortex breaker in question is housed completely within the fluid discharge pipe.
  • a vortex can form in the tank above the tank outlet, i.e. in terms of flow, upstream of the tank outlet.
  • the vortex breaker counteracts the formation of this vortex.
  • the vortex breaker is installed completely inside the fluid discharge pipe so that it does not protrude into the interior of the tank - and surprisingly still achieves the desired effectiveness.
  • the turbulence breaker does not interfere with the mixing of the fluid in the tank. Even during the filling process, the inflow is not significantly impeded by the turbulence breaker.
  • the tank system comprises in any case a tank with at least one tank outlet and a fluid discharge pipe connected to it, in which a vortex breaker is accommodated.
  • the tank system can also comprise further elements, such as further tanks, further fluid discharge pipes and additional lines.
  • the tank outlet is the opening in the tank wall through which the fluid is drained.
  • the fluid drain pipe is a line that is directly connected to the tank outlet and through which the fluid flows out of the tank.
  • the fluid drain pipe can also be made up of several parts.
  • the task is to create a possibility to use a known vortex breaker more advantageously.
  • the solution to the above problem is achieved by using a vortex breaker, which preferably consists of several radial fins that form fluid discharge channels between them and meet radially in the middle of the pipe. Ideally, the fins become wider radially outwards in the circumferential direction.
  • the vortex breaker is installed completely in a fluid discharge pipe of a tank system.
  • the vortex breaker is installed in the area of the fluid discharge pipe that ends at a maximum distance of 20 cm, ideally at a maximum distance of 10 cm, from the tank outlet.
  • the use of such a vortex breaker counteracts the vortex that forms at the tank outlet when fluid is drawn out of a tank. Since the vortex breaker does not extend into the interior of the tank, the vortex breaker does not hinder any mixing of the fluid in the tank that takes place at a time when the fluid is not yet to be drained from the tank. The vortex breaker is also Inflow from the whirlpool breaker is not significantly impeded. Furthermore, fittings in the tank/container can continue to be used in accordance with their function, since the whirlpool breaker does not protrude into the tank/container.
  • the fluid flowing through the tank outlet would move both in a direction parallel to the longitudinal axis of the tank outlet and in a rotational movement around the longitudinal axis of the tank outlet.
  • the two overlapping flow directions would lead to the formation of the vortex described above.
  • the radial fins of the vortex breaker therefore serve to stop or at least slow down the rotational movement of the fluid around the longitudinal axis of the tank outlet.
  • the radial fins form the fluid drainage channels between them. These are separated from each other in the circumferential direction by the fins, so that several chambers are created through which the fluid can flow in the longitudinal direction of the axis, but not in the circumferential direction. As soon as the fluid flowing out of the tank through the tank outlet has flowed into the area of the fluid drainage channels, the rotational movement of the fluid in the fluid drainage channels in the direction around the longitudinal axis of the tank outlet is stopped at the fins. This means that a vortex cannot form in the first place.
  • each fin becomes wider "outwards in the circumferential direction". This means that each fin has a smaller thickness in the area where it meets the other fins, viewed in the circumferential direction, than in the area facing away from it in the radial direction.
  • the width preferably increases continuously.
  • a "fin” is therefore a section of the whirlpool breaker that has at least two parallel has flow guide surfaces along which the fluid can flow but not through.
  • Radial fins describes the orientation of the fins. Radial fins are arranged in the vortex breaker in such a way that the fluid flows along the flow guide surfaces of a fin in the longitudinal direction of the axis and the flow guide surfaces block a flow in the circumferential direction, i.e. a circular flow around the longitudinal axis.
  • the vortex breaker is accommodated partially or completely downstream of the tank outlet in a section of the fluid discharge pipe which forms an integral part of the tank at the factory, is molded onto the tank or is welded to the tank.
  • the tank manufacturer can specify a sufficiently large installation space for a turbulence breaker at the factory, which may fit a turbulence breaker supplied by the tank manufacturer and which can be installed if required.
  • the tank manufacturer can then carry out a pressure test, if required, to determine the pressure resistance of the tank after the section of the fluid discharge pipe has been welded or molded onto the tank.
  • the turbulence breaker can therefore be installed if required without the tank having to be pressure tested again.
  • factor in this context means that the section of the fluid drain pipe is already connected to the tank welded or formed before the tank is handed over to the end customer.
  • downstream of the tank outlet describes a position that is located after the tank outlet in the direction of flow of the fluid exiting the tank.
  • the vortex breaker is accommodated in the region of a pipe connection of the fluid discharge pipe and is held in position by the pipe connections.
  • the vortex breaker can be easily removed from the fluid discharge pipe, for example for cleaning. Because the vortex breaker is easy to install, different specially adapted vortex breakers can be installed as required for different types of fluids, so that ideal results can always be achieved.
  • the turbulence breaker is connected to a pipe connection seal that seals the two adjacent pipe connections.
  • the turbulence breaker can be fitted with a separate seal between the two pipe connections before assembly.
  • the turbulence breaker is completely downstream of the tank outlet in a completely
  • the fluid discharge line is housed in a part of the tank that is separate and can be removed from it.
  • the section of the fluid discharge line in which the swirl breaker is installed is therefore not a permanent part of the tank, but is only detachably connected to the tank when the tank is in use.
  • the tank system can easily be retrofitted with a swirl breaker as required, without the tank having to undergo another pressure test.
  • fluid discharge line is used synonymously with the term “fluid discharge pipe”.
  • the vortex breaker is housed within a portion of the fluid discharge pipe which is not more than 20 cm, preferably not more than 10 cm, from the tank outlet.
  • the vortex breaker is held in a seal or integrally connected to it.
  • the seal is used to connect two pipe connections of the multi-part fluid discharge pipe.
  • a "one-piece connection" is given when the swirl breaker merges into the seal in a material-locking manner or the seal forms a section of the swirl breaker that is made of a corresponding sealing material.
  • the turbulence breaker is used to retrofit existing tank systems that are already in regular operation with a turbulence breaker.
  • a vortex breaker adapted to the respective requirements can be retrofitted as required. This means that a tank system can be used to store various fluids or suspensions without causing undesirable vortex formation.
  • the swirl breaker can be manufactured using various manufacturing processes such as injection molding or 3D printing. This offers a wide range of design options.
  • the swirl breaker can also be made from a sealing material. so that it can simultaneously serve as a seal between the fluid discharge pipe and the tank or between two sections of the fluid discharge pipe.
  • FIG. 1 a tank system 1 according to the invention is shown schematically.
  • the tank system 1 comprises a tank 2 in which a fluid can be stored.
  • a first section 16 of the fluid discharge pipe 4 composed of several detachably connected sections 16, 17 is mounted on the outlet 3 of the tank 2.
  • the type of connection can either be designed such that the fluid discharge pipe 4 is detachably connected to a connecting element permanently provided on the tank 2, such as a thread.
  • the first section 16 of the fluid discharge pipe 4 itself can be permanently connected to the tank 2, for example by being welded to the tank 2.
  • the fluid discharge pipe is attached to the tank 2 before any pressure test is carried out to determine the pressure resistance of the tank 2.
  • a throttle valve 13 is provided in the second section 17 of the fluid discharge pipe 4. As long as the throttle valve 13 is closed, the fluid in the tank 2 can only flow out of the tank 2 as far as the valve 13. As soon as the fluid discharge pipe 4 is completely filled with the fluid in the area between the valve 13 and the tank outlet 3, no further fluid can flow out through the tank outlet 3 in the direction of the valve 13. If the valve 13 is opened, the fluid 2 flows out of the tank 2 via the tank outlet 3 and the fluid discharge pipe 4.
  • the tank system 1 has a pump 14, via which a negative pressure is generated on the line 15, which is a continuation of the fluid discharge pipe 4.
  • the valve 13 When the valve 13 is open, the fluid in the tank 2 can thus be pumped out of the tank 2.
  • the tank system 1 is equipped with a vortex breaker 9.
  • the functionality of the vortex breaker 9 and a possible way of installing the vortex breaker 9 in the tank system 1 is explained using the Fig. 2 and 3 explained.
  • Fig. 3 the tank 2 and the shown section of the fluid discharge pipe 4 are shown in the sectional view, while the vortex breaker is not shown in section.
  • the vortex breaker 9 consists of a sealing section 12, which also represents a flat or pipe connection seal 8.
  • the vortex breaker 9 has three fins 10.
  • the three fins 10 meet in the area of the longitudinal axis of the sealing section 12 (or of the vortex breaker 9) and merge into one another in one piece.
  • the extent of the three fins 10 in the direction parallel to the longitudinal axis of the vortex breaker 9 is significantly greater than the thickness of the sealing section 12 measured in the longitudinal axis direction.
  • Each of the three fins 10 has two surfaces 18 which run parallel to the longitudinal axis of the vortex breaker 9 and are also referred to as flow guide surfaces 18.
  • the Trombenbrecher 9 is mounted as Fig. 3
  • the sealing section 12 of the swirl breaker 9 is clamped between the two pipe connections 6 and 7 of the sections 16 and 17 of the fluid discharge pipe 4.
  • the sealing section 12 thus also serves as a pipe connection seal 8.
  • the fins 10 of the swirl breaker 9 extend from the pipe connections 6 and 7 in the direction of the tank opening 3. However, the fins 10 do not protrude into the interior of the tank 2.
  • Fig. 3 It can also be seen that the surfaces running orthogonally to the flow guide surfaces 18 of the individual fins 10 have a slight inclination, so that the vortex breaker 9 forms a point in the side view.
  • the fluid in the tank 2 flows through the outlet 3 in the direction of the fluid discharge pipe 4. In doing so, the fluid passes the swirl breaker 9. Without the swirl breaker 9, the fluid would not only flow in the direction parallel to the longitudinal axis of the tank outlet 3, due to various fluid mechanics phenomena. but also flow in a circle around them, so that a vortex is created. With the help of the vortex breaker 9, however, the circular flow of the fluid around the longitudinal axis of the outlet 3 is slowed down or largely stopped.
  • the vortex breaker according to the invention can not only be installed in tank outlets, it can also be used beneficially in any other pipe connection, especially if it is (optionally) a clamp or clamp connection.
