Definitions

  • the invention relates to a magnetic separator and a method for separating particles having ferromagnetic properties from a fluid.
  • the invention also relates to a magnetic separator for a fluid circulation system for circulating an amount of fluid, susceptible of containing suspended particles having ferromagnetic properties. More in particular the invention relates to a magnetic separator for a fluid circulation system for circulating an amount of fluid between heat exchangers, such as a heating or cooling system.
  • Fluid circulation systems with a magnetic separator to collect ferromagnetic particles from a fluid flow that is susceptible to contain such particles in suspension.
  • Fluid circulation systems especially heating and cooling systems, generally make use of large complex networks of pipes, valves, and heat exchangers. Incorporating magnetic separators into these complicated systems is not trivial, and typically leads to confined installations making operation of the magnetic separator difficult.
  • the invention provides a magnetic separator according to claim 1.
  • a magnetic separator is simple to operate, and owing to the flexible member, provides operational flexibility in what is typically a confined working environment.
  • a magnetic separator is known from Progalva catalogue "Catálogo 2010/2011”. Functioning of a magnetic separator with a movable magnet is shown in Progalva Iberica S.L. publication "Tratamiento Curativo de Circuitos, Filtro Magnetico”.
  • EP1445024A1 discloses a separator having a magnet, slidably housed in a sleeve inside a collection chamber.
  • the magnet can be positioned in a first position for collecting particles having ferromagnetic properties, and can be moved to a second position axially spaced from the first position for releasing collected particles having ferromagnetic properties.
  • a circulation system is simple to operate via the flexible member.
  • the flexible member provides operational flexibility in what is typically a confined working environment.
  • the fluid circulation system may be configured as a heating or cooling system.
  • the second path is substantially different from the first path.
  • the second path is substantially perpendicular to the first path.
  • the magnetic separator can be easily operated in an area not conflicting with ancillaries of the magnetic separator.
  • it may be advantageous that the second path is substantially perpendicular to the first path.
  • the second path is substantially parallel to and offset laterally from the first path.
  • the second sense is opposite to the first sense. This may be desirable for severely cramped installations.
  • the magnetic separator further comprises a redirecting element.
  • the redirecting element is adapted to transfer the flexible member and/or its movement from the first path to the second path at an intersection, or projected or virtual intersection, of the first path and the second path.
  • the redirecting element controls the transition of the flexible member or its movement from the first path to the second path and/or ensures that the transition occurs smoothly.
  • the redirecting element may be a pulley, a (metal) guide, a deflector, a crank, or like element.
  • the flexible member extends through a bottom wall of the magnetic separator. It is conceivable that the flexible member extends through a top wall or a side wall of the magnetic separator depending on the predefined first path and other features of the magnetic separator.
  • the magnetic device is movable from a first position for collecting particles having ferromagnetic properties to a second position axially spaced from the first position for releasing collected particles having ferromagnetic properties.
  • the magnet device is biased into the first position or the magnet device is biased into the second position.
  • the magnet device is further movable from the second position for releasing the particles having ferromagnetic properties to a third position axially spaced from the second position for discharging the particles having ferromagnetic properties.
  • the flexible member allows the magnetic separator to cycle through collecting, releasing, and discharging particles having ferromagnetic properties.
  • the flexible member is calibrated to provide an indication as to which position the magnet device is located in.
  • the indication is a marking on the flexible member.
  • the location of the magnet device may not be ascertainable from the outside of the magnetic separator. It is therefore desirable that the flexible member is calibrated to provide an indication as to which position the magnet device is located in.
  • the flexible member includes markings such as first position, second position, etc. It is also possible that sections of the flexible member are a different color in order to give an indication of the magnet device's location. For example red may indicate that the magnet device is in the second position.
  • the flexible member is arranged to provide sensory feedback when the magnet device is located in one of the first position, second position, and third position.
  • the flexible member includes protrusions arranged to provide sensory feedback in the form of resistance when the magnet device is located in one of the first position, second position, and third position. It is conceivable that the magnetic separator is installed in a dark environment where it would be difficult to interpret the calibrated flexible member. In such cases it is desirable to provide sensory feedback, such as a force, resistance, vibration, tactile information, sound or light. Providing alternative sensory feedback ensures that the magnetic separator can be operated effectively in a wide range of environments. Sensory feedback may also be used to control or for monitoring automated operation of the magnetic separator.
  • the first position is located in a middle region of the magnetic separator and the second position is located in a lower region of the magnetic separator.
  • the third position is located at a base of the magnetic separator.
  • the magnet device is biased by a resilient member.
  • the resilient member is a tension spring. It is also possible that the resilient member is one of a coil spring, compression spring, and a resilient plastic. Such resilient members are simple, cost effective, and robust.
  • the magnetic separator further comprises an actuating device adapted to actuate the flexible member.
  • the actuating device is a handle and the actuating device is driven manually by a pulling motion. This provides a simple and robust interface for operating the flexible member of the magnetic separator. It is also possible that the actuating device is one of a loop, a grip, and a hook.
  • the actuating device includes a motor adapted to drive the flexible member.
  • the actuating device is driven by a motor.
  • the motor may be controllable via a switch.
  • the actuating device comprises a controller adapted to drive the motor at predefined intervals. This is ideal when the magnetic separator is located in a remote or inaccessible location, and/or when the magnetic separator must be operated frequently owing to the inherent characteristics of the system in which it is applied.
  • the flexible member is one of a cable, a string, a chain, and a flexible rod.
  • the elongate flexible member is flexible in view of bending relative to a direction of elongation.
  • the elongate flexible member is resistant against extension in the direction of elongation.
  • the magnetic device includes at least one permanent magnet.
  • the at least one permanent magnet is one of a rare earth magnet, a ceramic magnet, a ferrite magnet, a neodymium magnet, a samarium cobalt magnet, and an alnico magnet.
  • Permanent magnets offer flexibility and allow the magnet separator to be easily adapted to a specific fluid circulation system. Furthermore, these magnets are commercially available in a multitude of shapes, sizes and strengths.
  • the magnetic separator includes a plurality of magnetic assemblies positioned in the fluid flow path interiorly of the collection chamber.
  • Each magnetic assembly of the plurality of magnetic assemblies includes a respective substantially tubular sleeve, a respective magnetic device, and a respective substantially elongate flexible member.
  • the respective flexible members of the plurality of magnetic assemblies are arranged to be actuated as a group. Actuating the flexible members as a group allows the respective magnetic separator to remain simple and easy to operate yet at the same time allows the efficient collection of particles having ferromagnetic properties in large systems and/or large magnetic separators.
  • the present invention also relates to a method for separating suspended particles having ferromagnetic properties from a fluid according to claim 12.
  • the method includes actuating the second end of the flexible member along the second path in the second sense so as to move the magnet device between a first position for collecting particles having ferromagnetic properties to a second position axially spaced from the first position for releasing collected particles having ferromagnetic properties.
  • the method includes actuating the second end of the flexible member along the second path in the second sense so as to further move the magnet device from the second position for releasing the particles having ferromagnetic properties to a third position axially spaced from the second position for discharging the particles having ferromagnetic properties.
  • a magnetic separator 1 is shown schematically.
  • the magnetic separator 1 is part of a fluid circulation system for circulating an amount of fluid between heat exchangers.
  • the fluid circulation system in as far as it is conventional, has been omitted from Figure 1 for clarity.
  • the amount of fluid that is in circulation between the heat exchangers such as a heating or cooling system, enters a collection chamber 3 through an inlet 5 and leaves the collection chamber 3 through an outlet 7.
  • the fluid flow path is indicated by arrows 5A and 7A.
  • the inflow of fluid through inlet 5 is a flow of fluid that is susceptible of containing suspended particles that have ferromagnetic properties. Such particles are often found in heating systems and may have originated from wear of parts, such as pumps and valves within the fluid circulation system.
  • the collection chamber 3 has a hollow interior 9 that is normally filled with the fluid that is in circulation. Also exposed to the fluid in circulation is a substantially tubular sleeve 11 that is accommodated within the hollow interior 9 of collection chamber 3. Contained for translatory movement in the substantially tubular sleeve 11 is a magnet device 13. Thus the substantially tubular sleeve 11 defines a predefined, in this example linear, first path indicated by dashed line 16A. In Figure 1 the magnet device 13 has its North pole N and south pole S aligned with a direction of the translatory movement of the magnet device 13 along the predefined first path 16A.
  • the tubular sleeve 11 is of substantially non-ferromagnetic material, so that in the position shown in Figure 1 the magnet device 13 has its magnetic field extending to the exterior of an upper portion of the tubular sleeve 11. Also positioned within the interior 12 of the substantially tubular sleeve 11 is an auxiliary sleeve 15 of ferromagnetic material. The interior 12 of the tubular sleeve 11 is fluid tight, so that the circulating fluid has no access to the magnet device 13.
  • the magnet device 13 as shown in Figure 1 is kept in its first position in the upper portion of the sleeve 11 against the action of a resilient member, in this example embodied as a compression spring 17, by means of an elongate flexible member, in this embodiment the elongate flexible member is cable 19.
  • the flexible member 19 is attached to the magnet device 13 at a first end 19A.
  • the flexible member 19 comprises a second end 19B which extends externally of the sleeve 11.
  • the magnetic separator 1 may also be provided with an inlet valve 23 associated with fluid inlet 5 and an outlet valve 25 associated with the fluid outlet 7. Further the sleeve 11 may be closed by a bottom 27 to ensure its fluid tightness independent of the collection chamber 3.
  • the collection chamber 3 may optionally also be provided with a discharge drain 29, which may have an associated drain valve 31.
  • the magnetic separator is shown with its magnet device 13 positioned at a second position, in a lower portion of the sleeve 11, in which its magnetic field is eliminated (or at least diminished) by the auxiliary sleeve 15 of ferromagnetic material that forms a short circuit for the magnetic field.
  • the elimination or diminishing of the magnetic field allows the collected ferromagnetic debris particles to be extracted from the collection chamber 3.
  • the magnet device 13 By actuating the second end 19B of the flexible member 19 so as to move along a second path, indicated by dashed line 16B, the magnet device 13 is caused to travel in a first sense from the first position in Figure 1 to the second position illustrated in Figure 2 .
  • the resilient member here compression spring 17, is released and the cable 19 moves along the first path 16A and along the second path in a second sense indicated by arrow 33.
  • the first path 16A is perpendicular to the second path 16B.
  • the magnet device is biased into the second position by the resilient member.
  • a redirecting element in this example embodied as pulley wheel 18, transfers the movement of the flexible member, cable 19, from the predefined first path 16A to the second path 16B.
  • the lower end of the substantially tubular sleeve 11 also has an enlarged diameter.
  • the enlarged lower sleeve diameter further reduces the magnetic field strength experienced by the collected ferromagnetic debris particles 21, allowing them to be extracted from the collection chamber 3 because there is no magnetic field strong enough to retain them.
  • the ferromagnetic debris particles can sink to the bottom of the collection chamber 3 due to gravity.
  • the drain valve 31 for flushing the collected particles 21 through the discharge drain 29. It will be clear that some of the circulating fluid will be discharged together with the particles 21. It will be appreciated that it is also possible to halt the circulation of the circulating fluid prior to opening of the discharge drain 29.
  • the inlet and outlet valves 23, 25 may be closed and a portion of the circulating fluid may be allowed to be drained off through the discharge drain 29 when the drain valve 31 is opened. This purging of magnetically collected contaminations needs only be performed periodically and at relatively large time intervals. To ensure proper draining and preventing the entrance of air, the closing of the outlet valve 25 may be timed to precede the closing of the inlet valve 23 in an amount sufficient to ensure replenishment of the interior 9 of the collection chamber 3.
  • the operation of the various valves can be entrusted to an automatic control device which may be triggered by programmable software.
  • the inlet and outlet valves 23, 25 may also be arranged to bypass the magnetic separator when the purging process is being carried out. It is also possible to use a separate flushing fluid to carry the collected particles from the collecting chamber 5 to the discharge drain 29.
  • the magnet device 13 is shown between the walls of auxiliary sleeve 15.
  • the magnet device 13 may suitably be a permanent magnet of, e.g. sintered, rare earth materials, ferrite, neodymium, alnico or samarium cobalt.
  • One particularity of magnets is that the magnetic field lines 35 at the opposite North and South poles N, S extend in an axial direction, from which these are gradually deflected radially outwardly.
  • caps 39 of ferromagnetic material such as iron or steel, the field lines 35 can be deflected in a radial direction at a shorter distance, as shown in Figure 4 and 5 .
  • Such ferromagnetic caps 39 not only improve the short cutting effect of the auxiliary sleeve 15, but also ensure an improved attraction of particles suspended in the circulating fluid, when the magnet device 13 is in its first position shown in Figure 1 .
  • magnetic separator 101 is also provided with a collection chamber 103 that has an inlet 105 and an outlet 107A.
  • a substantially tubular and fluid tight sleeve 111 is positioned within the flow path between the inlet 105 and the outlet 107.
  • a magnet device 113 of the kind described with respect to Figures 1-5 is again accommodated within the substantially tubular sleeve 111 for translatory movement therein.
  • the substantially tubular sleeve 111 defines a predefined, here linear, first path indicated by dashed line 116A.
  • the magnet device 113 can be moved along the predefined first path 116A in a first sense from a first position, located in a lower portion of the tubular sleeve 111, to a second position, located in an upper portion of the tubular sleeve, by a elongate flexible member.
  • the elongate flexible member is cable 119, which partly moves along a second path, indicated by dashed line 116B, in a second sense indicated by arrow 133.
  • the flexible member 119 is attached to the magnet device 113 at a first end 119A.
  • the flexible member 119 comprises a second end 119B which extends externally of the sleeve 111.
  • the first path 116A is perpendicular to the second path 116B.
  • a redirecting element, pulley wheel 118 transfers the flexible member, cable 119, from the predefined first path 116A to the second path 116B.
  • the magnet device 113 is positioned within an auxiliary sleeve 115 of ferromagnetic material against the action of a resilient member, here compression spring 117.
  • the resilient member, compression spring 117 in the second embodiment biases the magnet device 113 into the first position
  • An upper end of the substantially tubular sleeve 111 has a frustoconical shape with an upwardly increasing diameter.
  • the magnet device 113 In its first position, the lowermost position, the magnet device 113 attracts ferromagnetic particles that are in suspension in the circulating fluid.
  • the substantially tubular sleeve 111 is of a non-magnetic material, so that the magnetic flux lines of the magnet device 113 extend to the exterior of the tubular sleeve 111, which closely surrounds the magnet device 113.
  • the ferromagnetic particles 121 are collected around the lower part of the tubular sleeve 111.
  • the magnet device 113 When the magnet device 113 is retracted against compression spring 117 in its second position, the upper most position, as shown in Figure 7 the collected particles are no longer under the influence of a magnetic field and are released. The collected particles can now be drained through a discharge drain 129.
  • an outlet valve 125 will first have closed the outlet 107 so that the collected debris cannot continue in the fluid circulation system. Rinsing of the high concentration of debris 121 in the collection chamber 3 can be done by the circulation fluid by continuing allowing the fluid to enter through inlet 105. However a certain amount of fluid will be lost from the system through the discharge drain 129 for as long as the drain valve 131 is kept open and the outlet valve 125 closed. It may therefore be preferred to provide a bypass for the circulating fluid and execute the inlet valve 123 as a selector valve that redirects the circulating fluid into a bypass and at the same time connect to a rinsing fluid that is allowed to enter the collection chamber 3 through the same inlet 105.

  • ferromagnetic dirt particles can be discharged from the system while the system is in operation. Since discharging of the collected particles can be performed in a very short time, it is not necessary to shut down or bypass the fluid circulation.

  • An upper end of the tubular sleeve 211 is closed in a fluid tight manner by an end plug 227.
  • Attached to the end plug 227 in an interior 212 of the tubular sleeve 211 is a resilient member, tension spring 217, which has an opposite end thereof connected to a sliding magnet device 213.
