Definitions

  • the invention relates to a filter module for liquids.
  • Such liquid filters are known from DE-PS 32 09 216, in which a hollow cylindrical filter element is provided. This separates a filtrate space from a dirty liquid space within a filter housing.
  • the liquid filter also contains a dirt drainage channel, which is arranged parallel to the axis of the filter element and has a U-shaped cross section. To clean the surface of the liquid filter, the latter is rotated about its axis and the dirt discharge channel is opened, so that liquid flows through the filter fabric arranged on the surface of the filter element due to the pressure prevailing inside the hollow cylindrical filter element. The particles adhering to the filter fabric are carried along by the flow and discharged via a dirt drainage channel.
  • the size of the particles contained in the liquid to be cleaned cannot be defined exactly, so that under certain circumstances particles are also washed up which have a multiple of the filter gap.
  • the cleaning of such particles with the known backwashing device is made more difficult by the fact that this backwashing device on the one hand has a U-shaped cross section that is as closed as possible and only open to the filter area, but on the other hand larger particles on the circumference of the filter element should also get into the dirt drainage channel. This results in a not inconsiderable gap at the front edge of the dirt drainage channel, through which liquid enters the dirt drainage channel from the dirty liquid space. This significantly reduces the backwashing action on the filter element.
  • a gap filter for lubricating oil which is provided with a cleaning element.
  • the cleaning element has a rinsing channel and on the one hand has openings facing the filter surface for backwashing the gap filter and an inlet gap for pre-cleaning the filter surface.
  • coarse dirt is to be removed on the one hand by means of the inlet slit, and the dirt accumulated in the filter slits via the backwashing openings.
  • a disadvantage of this system is that the backwashing effect is greatly reduced by the arrangement of the inlet gap for coarse dirt.
  • the cleaning element which has a compact combination, has the disadvantage that dirt of different compositions cannot be removed effectively.
  • the inlet gap should be kept as small as possible so as not to unnecessarily influence the backwashing effect.
  • a smaller inlet gap has the disadvantage that coarse dirt is deposited in front of the cleaning gap and cannot be removed with it.
  • the low backwashing effect of the cleaning element is further reduced by backwashing a very wide circumferential area of the filter and thus greatly reducing the speed of the backwashing flow.
  • a backflushable liquid filter is known from DE 28 52 611 A1, which has a conical filter cage which is flowed through from the outside inwards and is firmly anchored in a housing provided with an inlet and an outlet.
  • the disadvantage here is that the conical arrangement of the filter cage in particular means that the filter can be adapted to changing boundary conditions, e.g. B. by an extended centerpiece, or by a centerpiece with a changed radius is not feasible.
  • the invention has for its object to provide a filter that avoids the disadvantages mentioned and with the dirty liquid, which is loaded with particles of different sizes, is always optimally filtered and an effective cleaning of the filter element takes place, the assembly being highly adaptable per se should have changing boundary conditions.
  • This object is achieved in that components are combined to form a module and in that means are provided with which the components are connected to one another, the module having an upper part and a lower part and at least one central part, the module having at least one raw liquid inlet and has a clean liquid outlet and at least one dirt retention device.
  • any number of middle parts in particular with different lengths and / or diameters, can be arranged in particular along the longitudinal axis, so that the assembly can be adapted very flexibly to changed operating parameters or can be extended as desired.
  • connection flanges to be positioned as required. Only the connection module is varied accordingly. It is also possible to use welded versions. Compared to the designs carried out by casting, these have the advantage that even small quantities can be easily realized.
  • connection flanges can be positioned just as flexibly since they can be arranged between zero and three hundred and sixty degrees and are therefore easily adaptable to existing systems. It is also conceivable to weld the various components together.
  • the assembly has at least one backwashing inlet and / or outlet and the filter backwashing device corresponding therewith. Furthermore, it can be provided according to the invention that the assembly has at least one cyclone, with the aid of which the coarser part of the dirt load can be separated out.
  • the assembly has at least one flow guide with which, depending on z. B. geometric sizes, such as the radius and the type of dirt, or their shape, weight or size, different flow profiles can be realized.
  • the possibility of designing the flow guiding device with a profile in which the flow velocity is maintained in the lower region is advantageous to design the flow control device in such a way that turbulent areas are avoided, which may adversely affect pre-separation. It has proven to be expedient to design the flow guide with a long length. This achieves an optimal cyclone effect. Especially in the lower area, a high degree of separation can be achieved due to the cyclone effect.
  • the assembly has at least one flow guide that is adjustable in height and thus can actively influence the flow guidance.
  • the assembly has at least one sludge trap with which the separation behavior, in particular of the coarse dirt, can be influenced or improved.
  • the dirt retention device has a gap filter insert.
  • Gap filters in particular when separating sludge, have excellent separating and backwashing properties, which come into their own in this modular arrangement.
  • filter stars in alternative developments, it is provided to use so-called filter stars, sheaths, or pockets.
  • screen, paper, foil, plate gap, wire gap or canned filter inserts in other alternative ven configurations conceivable to use screen, paper, foil, plate gap, wire gap or canned filter inserts.
  • a gap filter for the dirt retention device instead of a gap filter for the dirt retention device, other filter inserts can also be used.
  • screen cloth, foils or paper as a dirt retention device.
  • an adaptation of this device is conceivable.
  • the assembly has at least one dirt outlet.
  • the filter backwashing device of the assembly has at least one scraper which mechanically supports the backwashing process, reduces the backwashing phase and improves the result.
  • the assembly has a high degree of adaptability to changing boundary conditions.

  • the raw liquid then flows into the opening 30 and, according to the arrow 31, past the valve 32 into the raw liquid chamber, to the filter candle 33.
  • the cleaned liquid leaves the system via the pure liquid outlet 5.
  • Such a filter system has, for example, six or more filter cartridges, so that six or more valve systems are also provided. Each valve system controls the inflow or outflow to a filter candle or to a gap filter insert.
