Definitions

  • the present invention relates to a device for constructing a liquid-permeable floor covering plate, manhole cover or the like.
  • Such devices are known in the form of manhole covers, perforated base plates, even special filter plates.
  • EP 0 651 835 by the same author discloses a multilayer filter element in which the free flow cross sections of each filter layer increase from layer to layer in the flow direction.
  • the filter layers are formed from porous, firmly bonded materials such as porous concrete or asphalt layers that adjoin one another.
  • the aim of the invention is to further develop the known filter elements in such a way that they are extremely easy to manufacture, attachable and frost-resistant and have an improved self-cleaning effect.
  • This goal is achieved with a device which is characterized by two spaced-apart, perforated plates which are connected to one another by a peripheral wall and form a receiving space between them, the clear width of the perforations of the upper plate being substantially smaller than that of the lower plate.
  • the filter element according to the invention can be manufactured in the form of a round, angular or arbitrarily shaped cassette, cartridge or plate and, for example, inserted into the inlet of a waste water or exhaust air shaft or simply as a liquid permeable floor surface fastenings are placed on a draining surface.
  • the known sequence of increasing flow cross sections increases in principle that solids contained in the liquid to be filtered or to be removed can only penetrate into the first plate up to a certain grain size. Grain sizes that are equal to or smaller than the perforations of the upper plate are not retained in the filter device, but emerge through the lower plate.
  • the receiving space provided between the two plates allows the solids that have entered to move freely, so that they flow around the downstream drainage water and are reoriented until they emerge through the lower plate. The receiving space between the plates therefore decisively improves the discharge of any washed-in solids from the filter element.
  • the receiving space can in a particularly advantageous manner with a filter layer made of crushed stone, gravel, concrete granules or the like. be filled, the clear width of the flow cross-sections remaining between the granules of the filter layer between that of the upper and that of the lower plate.
  • the filter device according to the invention can be used both without and with filling.
  • a filter body can alternatively be inserted into the receiving space, preferably made of metal or plastic honeycombs or perforated knobbed panels, the clear width of its flow cross-sections being between that of the upper and that of the lower panel.
  • the filter layer or the filter body per se can already be filled in during the manufacture of the device and permanently absorbed in the device.
  • a closable opening for filling the receiving space is provided in the peripheral wall.
  • at least one of the plates can preferably be pivotably mounted on the peripheral wall into an open position.
  • at least one of the plates is connected to the peripheral wall via a detachable plug connection.
  • a particularly wear-resistant, robust and easy to manufacture embodiment of the invention consists in that the plates and the peripheral wall are made of sheet metal. Alternatively, production from wear-resistant plastic plates or elements is also conceivable.
  • FIGS. 5 and 6 show cross sections through two alternative embodiments of the invention.
  • the filter device shown in FIGS. 1 to 4 consists essentially of two square, perforated Plates 1, 2, which are connected to one another at their periphery via a peripheral circumferential wall 3 and form a receiving space 4 between them.
  • the clear width of the perforations 5 of the upper plate 1 is smaller than the clear width of the perforations 6 of the lower plate 2.
  • the plates 1, 2 can be made from any materials, but they are preferably formed from perforated sheets.
  • the peripheral wall 3 can also be made of sheet metal and welded to the plates 1, 2, riveted, screwed, glued, cast or the like. become.
  • the plates 1, 2 and the peripheral wall 3 can also be made of wear-resistant plastic plates or ducks.
  • the receiving space 4 can remain free or, as shown in Fig. 2, with a filter layer 7 made of granular material such as gravel, gravel, granular concrete or the like. be filled.
  • a filter body e.g. made of porous concrete, porous plastics, a grid, metal or plastic honeycomb, perforated studded panels, nonwovens or the like.
  • Such a filter body can be prefabricated inserted or inserted into the receiving space 4. In any case, it is essential that the clear width of the flow cross-sections remaining between the granules, pores, meshes etc. of the filter layer 7 or the filter body lies between that of the upper plate 1 and that of the lower plate 2, or is at all greater than that of the upper plate 5 is.
  • the filter layer 7 or the filter body can be introduced into the receiving space 4 during manufacture. However, it is better to provide an opening option through which the Filter layer or the filter body can be introduced later or inspected, cleaned or replaced if necessary.
  • an opening 8 is recessed in the peripheral wall 3 for this purpose, which here occupies the entire right side of the filter element and can be closed with the aid of a slide 9 which slides in corresponding guides 10, 11 .
  • FIG. 5 and 6 show alternative embodiments in order to create an opening possibility for the receiving space 4.
  • the upper plate 1 is pivotally supported by a hinge 12 on one side of the peripheral wall 3 in an open position (not shown).
  • the upper plate 1 is detachably connected to the peripheral wall 3 via a plug connection 13.
  • the opening can also be provided on the underside of the filter device.
  • additional support ribs 14 can be provided on the underside of plate 1 (FIG. 6) or plate 2 (FIG. 5).
  • peripheral shape of the plates 1, 2 can be round, oval, polygonal or irregular, as can the shape of the perforations 5, 6.
